Q:\DOCS\28431_1\TMN 1-5


1.8 Hazard Group Description

The scheduled project tasks have been evaluated for hazards associated with those activities andhave been assigned a particular Hazard Group. Table 1-2 describes these Hazard Groups. EachHazard Group represents a different potential for exposure and consequently has a correspondinglevel of personal protective equipment assigned to it. Each Hazard Group is described in detail inAPPENDIX A: STANDARD OPERATING PROCEDURES of this PHASP.

Work activities assigned to the same Hazard Group have similar exposure potentials, even if thework activities are different. In this way, the work activity and its exposure potential prescribesthe personal protective level, rather than the type of site or portion of the site where a workactivity is performed.

Q:\DOCS\28431_1\LAH 2-1

• Emergency Action PlanI

I should be advised to shut down and all personnel should evacuate to a safe area, as determined: by the Barr Project Health and Safety Team Leader. The signal method and possible safe area

. location(s) may vary depending on the type of emergency, size of site, and number of employees.'• This signal and location(s) to be used as a safe area should be discussed at the pre-construction

safety meeting and at daily "tool-box" meetings, if it has changed.

2.6 Emergency Evacuation Routes

Emergency evacuation routes should be identified prior to the beginning of site activities for eacharea in which work is performed. This evacuation route should be communicated to all Barremployees and Barr's subcontractors at the pre-construction safety meeting and at daily"tool-box" safety meetings, if it has changed.

In the event that an evacuation route has not yet been established for a work area and anemergency occurs, all Barr employees and Barr's subcontractors should attempt to evacuate to anarea of at least 100 feet upwind; 200 feet perpendicular to wind direction; or other areadesignated as safe by the Project Health and Safety Team Leader. Evacuation routes should beestablished to prevent isolation of personnel from other portions of the site. Barr employeesshould not risk personal safety, to save or salvage equipment in use at the time of evacuation.Emergency service providers should be contacted immediately and the Project Manager should benotified as soon as it is feasible.

2.7 Reporting Fires and Other Emergencies

When Ban* is primarily responsible for site activities, the Barr Project Health and Safety TeamLeader is responsible for contacting emergency service providers in the event of a fire or otheremergency. The Barr Project Health and Safety Team Leader should notify the Barr Health andSafety Manager and the Project Manager upon attainment of nonemergency conditions. TheProject Manager should make a recommendation to the owner's representative for notification oflocal, state, and federal governmental agencies.

2.8 Emergency Notification Procedures

The following course of action should be taken if an emergency situation develops:

a) Evacuate as necessary. Maintain site security and control as described in Section 1.6ofthisPHASP.

Q:\DOCS\28431_1\LAH 2-3

Emergency Action Plan

2.11 Decontamination Procedures

In the event of emergencies involving serious or potentially serious injuries, contact emergencyservice providers immediately. Decontaminate injured person(s) as much as possible prior totransport to a medical facility. Where hazardous substances cannot be removed at the site,consider use of clean tyvek to line the stretcher under the injured. Decontamination proceduresdescribed in FIGURE D-l of SECTION 4 and in APPENDIX D should be followed wheneverpossible.

2.12 PPE and Emergency Equipment

In the event of an emergency requiring emergency service providers, those providers should beproviding their own personal protective equipment and emergency equipment. Protectiveequipment used for this evacuation should be consistent with levels of protection and action levelsas determined in this PHASP.

2.13 Pre-Emergency Planning

Prior to the commencement of site activities, a hazard assessment will be made by the ProjectIndustrial Hygienists on the potential for emergencies occurring at the site. Based on this hazardassessment, the local emergency service providers will be contacted to determine their ability torespond to anticipated emergencies on-site. This contact is made so that this Emergency ActionPlan is compatible and integrated with the disaster, fire, and/or emergency response plansrequired by the local emergency service providers. Documentation of this written or telephonecontact and the hazard assessment will be kept in the project file.

As part of this pre-emergency planning, all Barr employees and flair's subcontractors shouldreview and become familiar with the hospital location map prior to the commencement of siteoperations to be used in the event of minor injuries such as splinters, stepping on nails, broken orcut fingers, etc. A map of the route to the hospital has been provided in SECTION 4 (FIGURE 3-HOSPITAL LOCATION MAP) of this PHASP.

Q:\DOCS\28431_1\LAH 2-5

Section 3: Record Keeping/Forms

3.1 Purpose

This section provides guidance for documenting field safety operations.

3.2 Project Health and Safety Plan

A field copy of this PHASP will be present at the site whenever operations are being conducted.All on-site Barr employees and all on-site personnel of Barr's subcontractors should review thePHASP. At the completion of the project, the field copy will be placed in the project safety file.

3.3 Safety Meetings

• Pre-cntry Safety Meeting: Prior to initiating site activities, the Project Health and SafetyTeam Leader should attend a pre-entry safety briefing with the Project Industrial Hygienist.

• Pre-construction Safety Meeting: The Barr Project Health and Safety Team Leader shouldhold a pre-construction safety meeting with Barr employees and Barr's other subcontractorson the first day of site activities, reviewing appropriate elements of this PHASP.

• Daily Tool-Box" Safety Meeting: Each morning a short "tool-box" safety meeting should beheld, which can be combined with other site-specific meeting topics.

Any Barr employee or on-site personnel of Barr's subcontractor joining the fieldinvestigation/remediation team will be required to go through a pre-construction safety meetingbefore participating in any field activities at the site.

CHAPTER 7: WATER AND ICE SAFETY

1.0 POLICY

The nature of Bait's work requires that, from time-to-time, Barr employees willhave to work in and near lakes, streams, and wetlands. Work during wintermonths may also require mat employees work on frozen water bodies. It is thepolicy of the company to provide for the safety of its employees who must workin such conditions through training, reference materials, careful project planning,providing proper equipment, and empowering its employees to make personaldecisions regarding the safety of any specific work site. No Barr employee isexpected to place him/herself or another person in an unsafe situation or asituation where they are unsure as to their safety regardless of the perceivedimportance of the work. Employees are expected to withdraw from any unsafe oruncertain circumstances and to contact the PM, PIC, and/or the Company Healthand Safety Manager to request assistance before proceeding further with the work.

2.0 WORK NEAR OR OVER DEEP WATER

Barr staff working on dams, bridges or other structures over water, where theymay be exposed to the risk of falling into the water, shall be provided with anduse US. Coast Guard approved Type I, n or in personal floatation devices (PFDs).Selection of appropriate PFD will depend on specific circumstances; if uncertain,contact Health & Safety staff. Ring buoys should be available at the site,positioned no more than 100 feet from the work area. At least one life-savingboat shall be available at locations where employees are working near or overwater in the event that rescue is needed (see Chapter 8, Boat Safety).

3.0 BUDDY SYSTEM RELATED TO WATER AND ICE SAFETY

A "Buddy System" for purposes of water and ice safety means having anotherperson nearby who can see you working, who is capable of and equipped to helpyou, and who has agreed to do so in an emergency. The person need notnecessarily be another Barr employee. The need for a "Buddy" is determined bythe specific site conditions and the nature of the work. Knowledge of conditionsat the worksite is important in making such decisions.

Project managers are expected to obtain sufficient information to make decisionsregarding the need for a "buddy" on a field assignment Such information mightbe obtained from an initial field visit to the site, from calling the client to requesttheir input or from sending an experienced Barr staff member to view the site as apart of planning the work. To avoid budget problems, such decisions ideally

7-1

Barr Health & Safety Policy Manual

need to be made in the proposal and project scoping stage of the work. Barr staffresponsible for carrying out the field assignment should request guidance on thisissue from the project manager. If, when they arrive at the site, conditions do notmatch what was anticipated, and if they believe mere is the need for a "buddy" toassist them, they are expected to call the project manager to request assistance inarranging for such help. They are not to proceed with such work until theyreceive proper assistance.

Use of the "Buddy System" also requires planning in terms of the skills andequipment needed to safely provide assistance. The "Buddy" is not expected toplace him/herself in danger to provide such assistance. Preparing a plan of actionahead of time for addressing different potential emergency situations shouldenable him/her to provide such assistance safely. However, it is also important tohave a backup strategy available including knowledge of emergency telephonenumbers, locations for medical assistance, etc.

4.0 WORKING ALONE IN OR NEAR SHALLOW WATER

When project circumstances require a Barr employee to work in or near shallowwater without a "buddy", (see Section 3.0, Buddy System Related to Water and IceSafety), other safety procedures should be followed. First, the site conditions mustbe known to the person performing the work. The initial site visit should bemade in the company of a "buddy" if the employee must enter the water to verifysite conditions. Secondly, Barr staff are encouraged to prepare a work itineraryand arrange a call-in schedule with the project manager or another Barr employeewhen working in these situations. If the person does not call-in within a pre-arranged window of time, a procedure will be implemented to find out what hashappened. While this cannot likely summon help for a short-term emergency, theprocedure can bring help in other situations.

Loud horns or alarms can also be used to summon help in areas where they canbe heard by other people. The Company has such horns available. They arelight-weight and can be attached to a belt If a person will be working in aremote area, having a portable phone nearby is also advisable.

Barr staff who will be working alone in or near shallow water must havecompleted a training course in water safety. The Company will rely on thetraining, experience, and judgement of such staff members to prepare to do suchwork safely and to avoid situations mat they regard to be unsafe.

) they may encounter on such worksites and bring appropriate equipment withthem to work safely. If site conditions are unknown, check with the project

• manager or PIC If site information is not available, a reconnaissance visit to the' site may be needed to properly plan the work. (See Section 3.0, Buddy System

Related to Water and Ice Safety.)

In still waters like lakes/ the condition of the bottom will likely be the determiningfactor regarding a hazard. An uneven bottom or a bottom with slippery rocks ordrop offs can cause falls. A soft and muddy bottom/ particularly with denseweeds, can also cause falls. Such hazards are also compounded by the need tocarry equipment With a solid bottom, waders may be appropriate. However,with a soft and weedy bottom, waders can be a hazard if the person falls.Weather permitting/ a swimming suit or old pair of jeans along with someinexpensive tennis shoes may be a better choice. In colder weather, a wetsuit ordrysuit may be needed. The same may apply to uneven or slippery areas. Inmany cases, a life jacket may be appropriate.

Moving water adds to the potential hazards described above. Streamflow, cross-currents and undertows can make work in even shallow water potentiallydangerous. Work near culverts and storm drains can potentially be dangeroussince vortex and other rotational flows near such structures can carry a personinto areas where they can become trapped due to the forces involved. Areasdownstream of dams and spillways can be particularly dangerous due to suchrotational flows and undercurrents. Barr employees are not to work in suchpotentially hazardous areas without a special safety plan addressing the hazardsand without prior approval by the PIC responsible for the work.

Water VelocitvFor work in shallow streams in areas that are free of the above described hazards,Figure 7-1 is presented as a guide to staff in deciding whether to enter a stream.As noted, this figure was obtained from a publication of the US. Department ofInterior Bureau of Reclamation addressing concerns related to dam breaks. Acurve has also been added to the figure representing the often referred to "rule of9" (a rule of thumb indicating it is dangerous to be in water where the product ofthe depth times velocity equals 9). Note that this curve falls into what is calledthe "High Danger Zone". It should be viewed as a limit above which a person

i —————-—————————————————————————————————_————————7-3

cannot reasonably stand in a stream and not as a guide for safety in working inthe stream. As indicated, the middle shaded area refers to die 'Judgement Zone".Barr staff are expected to use caution and good judgement in deciding to enter anarea of a stream with depth and velocity in this zone. Again, bottom conditionsand the amount of equipment to be carried will be a determining factor. Barrstaff are expected to avoid working in portions of a stream with depth andvelocity in the "High Danger zone" without preparation of a plan for safely doingso and prior discussion and approval of the PIC responsible for the work

Personal Floatation Devices (PFDs)US. Coast Guard approved PFDs may be required in certain cases of working inshallow water. PFD use should be addressed on a site-specific basis with theproject manager.

9.0 WORK ON FROZEN BODIES OF WATER

Barr staff may periodically have to work on a frozen-lake/ marsh or stream. Hiestrength or load bearing capacity of ice is quite variable and, therefore, caution isrequired to prevent accidents.

The Minnesota Department of Natural Resources (MDNR) has developedinformation concerning safety on frozen lakes and streams. Referencing researchby the US. Army Cold Regions Research and Engineering Laboratory, the MDNRindicates that the following factors each influence the strength of ice:

• ice thickness • how ice was formed• daily temperature • distribution of loading• snow cover • water chemistry• water depth under ice • presence of decaying vegetation• size of water body • water current• age of ice

Therefore, it is difficult to predict the strength of ice/ particularly over a large area.Ice thickness can vary, due to site-specific conditions. Work on rivers and streamsrequires special attention to safety. Localized flows near bridges and otherstructures, around trees and "deadheads", and near streams or springs can causethin ice. There is also concern related to falling through the ice in areas withunder-ice currents. A copy of an MDNR brochure is available from the Healthand Safety staff which provides more detailed information concerning iceproperties and recommended procedures in the event of breaking through the ice.

7-4

W«t»r and lc« Safety

The following guidelines and practices apply to Barr employees who must workon frozen water bodies:

1. Use the "Buddy System" whenever required to work on ice unless the"known" water depth is less than four feet Also use buddy system ifworking on ice over a stream with significant under ice current (1 fps ormore). If working alone, follow the procedure described in Section 4.0above.

2. Before heading out onto ice/ check with local people who are familiar withthe water body (bait shop owners, ice fishermen, the local sheriff, police orfire department etc.) Ask about any known hazards or areas to avoid.

3. When entering onto a frozen water body/ check the ice depth as youproceed, using an ice chisel or ke auger. Do not proceed if:

- the ice is less than three inches thick when walking alone on foot- the ice is less than five inches thick when using a snowmobile- there is standing water on the ice- the ice is visibly cracked, thawing or breaking up

4. It is the policy of the Company that staff not drive cars or trucks onto frozenwater bodies.

5. If you must carry a significant amount of equipment with you, considerpulling a toboggan. If walking to the work site is not practical, considerrenting a snowmobile with an accompanying sled or toboggan. Check theice carefully along the planned route, and operate the snowmobile inaccordance with all state and local laws. Snowmobile speed affects icesafety.

6. Anticipate the worst case (breaking through the ice)/ and bring alongequipment blankets and dry clothing to meet such emergencies. Theseitems should not be brought out onto the water body/ but rather left in thecar or truck, assuming it is reasonably nearby in the event of an emergency.If working on ice over water deeper than four feet, wear a Coast Guardapproved personal floatation device (FED) under your outer clothing. TheMDNR also recommends that people carry two short lengths of sawed-offbroom handle with sharpened nails on the ends, connected by a piece ofnylon string. If a person falls through the ice, the handles can be driveninto the ice and used to pull him/herself forward and up onto safe ice.

7-5

Barr Health & Safaty Policy Manual

Rather than stand up at this point, the person is advised to roll away fromthe broken ice.

7. If a person falls through the ice, after assisting them to safety, help them toa warm dry place. Depending on the period of time they have been in thewater, emergency medical care may be needed. Hypothermia is adangerous and potentially life threatening condition. Additionalinformation concerning hypothermia, expected survival times for differentwater temperatures, and related first aid is available from the Health andSafety staff.

CHAPTERS: BOAT SAFETY

1.0 POLICY

The nature of Ban's business requires that Company employees periodically workon rivers/ lakes, and wetlands in boats and other watercraft It is the policy of theCompany to provide for the safety of employees who work on such projectsthrough training, careful planning, providing equipment, and throughempowering employees to make personal judgements as to the safety of theirwork situations. Barr staff working in boats and other watercraft must havecompleted a training course in boating safety. Employees are also expected toperform all such work in accordance with state and federal requirements relatedto boating. A boat safety checklist should be completed and reviewed with theproject team prior to performing this work activity. No Barr employee is expectedto place him/herself, or another person/ in an unsafe situation or a situationwhere they are unsure as to their safety/ regardless of the perceived importance ofthe work

2.0 BOAT SAFETY CHECKLIST

The Boat Safety Checklist (Form 8-1) identifies a number of potential site hazardsassociated with working in watercraft The checklist also asks an employee toidentify ahead of time (to the best of his/her ability) the action to be taken inseveral potential emergency situations. The purpose of the checklist is to promptthe employee(s) involved in working on water to anticipate hazardous situationsthat could be encountered and to have an emergency response in mind if thecondition develops. Individual copies of the Boat Safety Checklist are availablefrom the Health and Safety Staff for use on individual projects.

Barr staff are encouraged to prepare a work itinerary and arrange a call-inschedule with the project manager or another Barr employee.

3.0 BUDDY SYSTEM RELATED TO BOAT SAFETY

A "Buddy System" for purposes of boat safety means having another personnearby who can see you working/ who is capable of and equipped to help you,and who has agreed to do so in an emergency. The second person or "buddy" caneither be in the boat or on shore. However/ if the second person is to be on shore,he/she must have continuous communication with the person in the boat (e.g.,walkie-talkie or dose enough to talk and hear), and he/she must also have a dearview of the person, the boat, and the area around the boat (approximately 200yards). The purpose is to enable the person on shore to keep the person in the

8-1

Ban- Health & Safety Policy Manual

boat informed as to what is occurring around him/her and warn them of anyhazards. Depending upon the specific river environment and the potentialhazards nearby, a third person may also be needed. The person need notnecessarily by another Barr employee. The need for a "Buddy" is determined bythe specific site conditions and the nature of the work. Knowledge of conditionsat the worksite is important in making such decisions.

Project managers are expected to obtain sufficient information to make decisionsregarding die need for a "buddy" on a field assignment Such information mightbe obtained from an initial field visit to the site, from railing the client to requesttheir input or from sending an experienced Barr staff member to view the site as apart of planning the work. To avoid budget problems/ such decisions ideallyneed to be made in the proposal and project scoping stage of the work. Barr staffresponsible for carrying out the field assignment should request guidance on thisissue from the project manager. If, when they arrive at the site, conditions do notmatch what was anticipated, and if they believe there is the need for a "buddy" toassist them, they are expected to call the project manager to request assistance inarranging for such help. They are not to proceed with such work until theyreceive proper assistance.

Use of the "Buddy System" also requires planning in terms of the skills andequipment needed to safely provide assistance. The "Buddy" is not expected toplace him/herself in danger to provide such assistance. Preparing a plan of actionahead of time for addressing different potential emergency situations shouldenable him/her to provide such assistance safely. However, it is also important tohave a backup strategy available including knowledge of emergency telephonenumbers, locations for medical assistance, etc.

Boat Safety

I Lights' Tail lights are required. Signal and brake lamps are recommended on all trailers

| and required if the hand signals of the driver of the signals of tile towing vehicle' are not visible to the following driver.

DrivingThe driver towing a trailer must maintain a distance of 500 feet between his or hervehicle and the vehicle ahead.

Brakes, Hitch and CouplingThe brakes must be in good condition. The hitch and coupling of the trailer mustmeet state standards. Safety chains are required.

Eurasian Water Milfoil (EWM) Other Weeds and OrganismsRemember to remove all weeds (particularly Eurasian Water Milfoil) from trailerand boat prior to exiting boat ramp. There are substantial fines for transportingEWM from a water body. There are also fines for transporting other types ofnoxious weeds and organisms as well Information concerning these other speciesis available from tile Health and Safety staff.

12.0 WEATHER

Summer StormsWeather is a major safety concern of boaters, and it can change suddenly. Noboater should start out in a storm. There are a number of good sources ofweather information. Before setting out, check local television and radio stations,call the Weather Forecast (612/375-0830), read the forecast in the newspaper, orcall the nearest National Weather Service office (612/725-6090).

Spring and Fall ConditionsWork in a boat or other watercraft during spring and fall conditions introducestile potential risks associated with hypothermia if a person falls into the water.The Health and Safety staff have information available, developed by theMinnesota Department of Natural Resources, which presents facts relating to"hypothermia" (the loss of enough body heat to lower the body temperature to adangerous level). The risk varies with water and air temperature, as well as withtile time spent in the water and/or cold air. Survival times can range from afraction of an hour to several hours, depending on water temperature, a person'sactivities in the water and the clothing or special equipment they are wearing.Employees who find it necessary to work in boats and other watercraft duringcold weather (cold water) conditions should obtain copies of the information

I ————————————————————————8-5

BarrH0arth& Safoty Policy Manual

available concerning hypothermia and incorporate appropriate procedures andequipment into their boating safety plan.

13.0 WORK ON RIVERS AND STREAMS

Normal Flow ConditionsBarr employees may periodically have to work in boats and other watercraft onrivers and streams. Moving water introduces the potential for a variety of boatinghazards that might not exist on still waters. A stream current carries the boat andits occupants toward continuously changing conditions, some of which could behazardous. Therefore, such work requires continuous attention to surroundingconditions, and a second person or buddy is required (see Section 3.0, BuddySystem Related to Boat Safety). Depending upon the specific river environment andthe potential hazards nearby, a third person may also be needed. Helmets mayalso be required for certain flowing water conditions.

Flood ConditionsPeriodically, Ban's projects may require working on or near a river or streamduring flood stage. Such conditions can produce potentially serious hazards.Higher flow velocities occur along with turbulence, the presence of logs, ice andother debris. The combination could potentially capsize and sink smallerwatercraft There is also the potential for the boat to get caught in debris,particularly around bridge piers and other structures, which could make itdifficult to escape. A buddy is required for work on or near a river or streamduring flood stage (see Section 3.0, Buddy System Related to Boat Safety). Helmetsmay also be required during flood stage.

Barr employees should first investigate alternative methods for accomplishing thework before proceeding to work in a boat during flood conditions. If noreasonable alternative is available, including postponing the work, Barr employeesare to proceed only after preparing a boat safety checklist mat addresses thepotential flood safety hazards and after receiving approval of the plan by the PICresponsible for the project The PIC may delegate such review and approval toanother Barr employee who has the required experience in working on andaround flood waters. Even with such pre-approval, employees are expected toevaluate the safety of the stream at the work site and, if safety conditions appearquestionable or different from those anticipated in preparation of the safety plan,they should not proceed. They should telephone the project manager/ the PIC orthe person who reviewed and approved the boat safety checklist to discuss thenext course of action. No Barr employee is expected to place himself, herself or

I _________________________________________________Boat Safety

fj another person in a dangerous situation, regardless of the perceived importance

of the work.

1 High Velocity FlowsThe forces associated with flowing water are proportional to the stream velocity.Water flowing in rivers and streams at velocities in the range of 5 to 6 feet persecond or faster should be regarded as potentially dangerous, even if it occurswithout flooding conditions. If the boafs motor fails and the boat becomes turnedsideways in the flow, it has the potential to be capsized if it strikes a fixed objectAn anchor line might be used in such a situation to try to keep the boat headedinto the current However, working in a boat in such stream velocities should beavoided, and a special safety plan and approval of the PIC responsible for theproject is required similar to work during flood conditions.

TugboatsWhen encountering a tugboat, remember the following:

• Stay dear of tugboats! They usually have the right-of-way over recreationalboats, and they create strong waves.

• Never anchor (without the engine running) in their course, they may require ahalf-mile or more to stop.

• At night their lights appear far apart compared to small boats.

• They have a "blind area" directly in front of the barges.

• Stay dear of the stern of tugboats. They may suddenly turn on a burst ofpower that could potentially overturn a small boat

• Turn your bow into the wake of barges and boats.

• When meeting a tugboat and barge at a bend in the river, move to theinside of me bend where possible.

Ban* Health & Safety Policy Manual

Wine DamsTo help improve the navigability of the Mississippi and other rivers by controllingthe direction of channel flow, the US. Army Corps of Engineers has placednumerous wing dams in navigable rivers.

A wing dam is an elongated pile of rocks, concrete, or other materials extendingout from the shore, often perpendicular to the flow, and typically submerged andnot marked They are often placed along a river on the outside of river bends forthe purpose of keeping the major portions of the flow in a main navigationchannel They can extend to 100 feet or more into the river. Because wing damsoften lie just below the water surface, they typically cannot be visually detectedand can pose a danger to the unwary boater. If these boating practices arefollowed, submerged wing dams may be avoided.

• When moving, stay within the main channel, indicated by buoys andmarkers. The main channel is regularly dredged and maintained to providerelatively hazard-free boating.

• If approaching shore, proceed slowly from a perpendicular angle.

• Navigation charts showing approximate locations of wing dams may beavailable for the area from the Corps of Engineers and can sometimes bepurchased at map stores.

• Stay clear of ripples in the water surface, these are tell-tale signs of a wingdam or other obstruction lying just below.

_ /Locks and Dams - Restricted AreasThere are certain restricted areas to protect boaters in the vicinity of locks anddams. Boats may not enter the following areas without preparation of a specialsafety plan. If it is necessary to be closer, special safety measures may need to betaken.

• the area 600 feet upstream and 150 feet downstream from a dam (includingauxiliary locks not in service);

• the area 600 feet upstream from a spillway.

Additional restrictions may be posted at each dam or spillway. Obey all signs.

APPBDOC A: MM STANDARD OPEMTMO PROCEDURES

1.0 PURPOSE

The Project Health and Safety Plan (PHASP) is aimed specifically at protecting workers from health and safety hazardsarising from hazardous substances and/or physical hazards known or suspected to be present at this site. The PHASPincludes safety procedures to be followed during anticipated site operations and emergency procedures to beimplemented in the event of an injury, fire, accident, or hazardous substance release on site.

The PHASP has been developed based on the guidance contained in the following regulations and guidance documents:

Occupational Safety and Health Administration COSHA) Standards, 29 CFR 1910 and 1926.U.S. Environmental Protection Agency (USEPA) "Standard Operating Safety Guides.* Noveaber 1986.NIOSH/OSHA/USCG/EPA •Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities.*October 1985.

• Barr Corporate Health and Safety Policy Manual, March 1992.American Conference of Governmental Industrial Hygienists (ACCIH); Threshold Liaiit Values* for ChemicalSubstances in the Work Environment/ 1991-1992.

The PHASP is beted upon information available at the time of preparation and is subject to revision or modificationas new data and information become available. The revision dates, if applicable, are listed on the title page, andw i l t be included in the next PHASP update.

Specific questions regarding the PHASP should be addressed to the Project Manager or the Project IndustrialHygienist. Questions that cannot be adequately addressed by either the Project Manager or the Project IndustrialHygienist will be referred to the Barr Health and Safety Manager or the Principal-in-Charge. The PHASP w i l l bereviewed annually and updated, if necessary, at that time. The PHASP may be modified between annual update periodsby amendment. A field copy of the PHASP should remain on-site to be made available to all on-site project personneland subcontractors.

2.0 APPLICABILITY

The PHASP applies to all on-site Barr employees and Barr's subcontractors who participate in investigation, remedialaction, construction activity, or other field activities. The formal adaption procedure of a PHASP is part of thecontract documents. Subcontractors should write their own PHASP. and it should include all requirements listed inSECTIONS 1, 2, and 3 of Barr's PHASP. which addresses project health and safety information, emergency action plan,and recordkecping procedures. The subcontractors PHASP should be reviewed by Barr's health and safety staff.Subcontractors may adopt, in writing, Barr's PHASP, by using the PHASP Adoption Form.

3.0 SITE SECURITY AID CONTROL ' .

The purpose of sit* security and site control is to protect the public fro* a site's chemical and physical hazardsand to Ua)it access to the site by the general public and unauthorized persons when necessary. The site perimeterMy be delineated by an existing fence I ins, boundary Barkings, or through the use of a security patrol. Individualsite work zones May be delineated within this boundary. If necessary, signs may be posted to prevent unauthorizedentry onto the site. Specific site control measures are described in SECTION 1: PROJECT HEALTH AND SAFETYINFORMATION of the PHASP.

4.0 HAZARD GROUPS

4.1 Hazard Croup Analysis for Project Tasks

A Hazard Group analysis assesses the hazards associated with a particular task on a project site and Batchesthat task to a Hazard Croup. There are five hazard groups, and each has been described in Table A-1, HazardCroup Description. Each hazard group represents a different potential for exposure and consequently has beenassigned a corresponding level of personal protective equipment (PPC).

The Hazard Croups are differentiated by anticipated concentrations of hazardous substances which may beencountered during work activities. 'Low*, *msdiua' and 'high* classifications differentiate Hazard Croups2, 3 and 4. A qualitative description of these concentrations of hazardous substances follows:

'Low' • No pure-phase product containing a hazardous substance expected in either groundweter orsoils. Work activity say require sew contact, principally walking over soil or contactingsoil or groundwater known or suspected to contain hazardous substances with the hands.Previous evaluation of site work has determined that akin contact does not present asignificant exposure pethwey. The primary purpose of PPE is to prevent hand to southcontaminant transfer.

*Moderate* « Pure-phase product containing a hazardous substance Bay be present. Work activity involveshandling contaminated soils or groundweter but contact with the torso is expected to beminimal (i.e. prolonged or frequent body contact is not expected and no splash potentialexiats).

PROTOTYP\PHASPAPP.93A A-2 Edited: Nay 7. 1W5


'Hioh" • Pure-phase product containing a hazardous substance is known to be present during workactivity and the potential for whole-tody contact ranges from possible to unavoidable (i.e.prolonged or frequent body contact Js, expected and/or splash potential exists).

5.0 ON-SITE WORK ZONES

On-site control minimizes potential contamination to other cite areas and facilitates safe work activities. Sitecontrol Mthods include the designation of site work zone* at the project site, and decontamination of fieldpersonnel and equipment.

Five work zones My be established on a site: the hot zone, the exclusion zone, the contamination reduction zone(DECON), the Mork area, and the support zone. On a complex site all five work zones My be established. On a simplesite there Bay only be three work zones (exclusion zone, DECON zone, and support zone). On a site involvingactivities which do not involve hazardous substances, there mey only be one work zone (work area).

These zones My be defined by physical or visual segregation of work activities, terrier tape, spray painted lines,traffic cones or other physical Mrkers Mill be used to delineate a nork zone area if it is unclear.

These five work zones are defined es follows:

5.1 Hot Zone

A hot zone is contained within the exclusion zone (see 5.2 below) and is an area where hazardous substancesere known to be present and a high potential for exposure exists. A hot zone is used to delineate testtrenching end contaminated soil excavation activities. Work activities in a hot zone usually are designatedas Hazard Group 4.

5.2 Exclusion Zone

An exclusion zone is defined as the area where hazardous substances are expected to be present, or whereselected physical hazards may be present because of site activities. All personnel entering the exclusionzone oust wear the appropriate protective equipment and coaply with appropriate procedures to work in thatzone. The purpose of an exclusion zone is to control access into an area where hazardous substances arepresent and to minimize cross-contamination to the noncontamineted portions of the site.

An exclusion zone designation is required when any of the following conditions exist:

• The site activity is a cleanup operation on a hazardous waste site.• The site activity is an initial investigation at a gonrnmsnt identified site before the presence or

absence of hazardous substances has been ascertained and there is a reasonable possibility forexposure.

• hazardous substances are present at the ground surface.

•»OTOTYP\Wtt$»A»*.93A A-S tditad: My 7. 1W3


• An intrusive activity will be conducted and there is a possibility for exposure through skin absorptionor irritation, or eye irritation.An intrusive activity will be conducted and there may be a possibility for exposure which may exceede work place exposure standard or IDLH concentrations.An intrusive activity will ba conducted and there may ba a possibility for fire or explosion.

5.3 Contamination Berhtrtien fDECOJO Zone

A contamination reduction (OECON) zone is the area which all iarr employees and iarr's subcontractors aust passthrough to enter or exit an exclusion zone. A DCCON zone is an area suspected to be clean (uncontaminated).

• It is located adjacent to an exclusion zone as a buffer between: (1) the area where hazardous substances areknown or suspected to be present; and (2) the area known or suspected to ba clean. Personnel and monitoringequipment decontamination activities occur In this zone.

Supplemental personal protective equipment (such as surgical gloves, chemical apron, face shield, etc.) maybe required for the performance of selected tasks in this zone. Sample handling and examination and thepacking of sample containers into transporting containers, where the only potential for cross-contaminationis from the sample container, may occur in a DECQN zone. Decontamination of heavy equipment (e.g. drill rigsand drain hole equipment, backhoes, etc.) should be conducted in this zone.

5.« Work Area

The work aree is thst portion of a site where work activities are being performed, and where no hazardoussubstances ere expected to be encountered. The work area is generally not included in another designated zone(i.e., hot zones, exclusion zones. DECOM zones, or support zones). The purpose of a work area is to controlaccess due to physical hazards. Basic ssfety equipment such as hard hat, steel-toed work boots/insulatedsteel-toed boots, and sefety glasses (Level 01) ere required in the work area unless otherwise specified inPMASP. Portions of the work area may be subject to the provisions and requirements of safety plans or healthand ssfety plans of other employers performing activities in the work area.

5.S Support Zone

A support zone is located in an aree thet is not known or expected to contain hazardous substances. Thephysical hazards that are common to the site ere generally not present. Support materials (clean protectiveequipment, supplies, etc.) will generally be located in this zone. Personal use articles, such as vehicles,telephones, office trailers, and sanitation facilities can be located in this zone. Basic personal safetyequipment (hard hat, steel-toed work boots/insulated steel-toed boots, and safety glasses) are generally notrequired in this zone.

PtOTOTYPVPllASPAPP.WA A-e Edited: Nay 7. 1993


A support zone may be established at a site based on the following considerations:

• The support zone area is not suspected to be contaminated.• The location of a contamination reduction (DECON) zone is adjacent to support zone.• The availability of services or ability to provide aervices, such as electric power, telephone, water,

roads, etc. are convenient to the support zone.• The support zone is upwind of site activities.

Eating, drinking, and smoking may be permitted in selected portions of a support zone or a work area.

6.0 BUDDY SYSTEM

The buddy system is a system whereby each member of a project field team has a specific agreement with at least oneother member of the field team to mutually maintain line-of-aite communication and provide rapid assistance in theevent of an emergency.

Entry into the exclusion zone or hot zone requires implementation of the buddy system. The only work zones thatdo not require the use of the buddy system are the DECON zone, the work area, and the aupport zone.

To properly utilize the buddy system, all applicable Mrr employees and Mrr's subcontractors are assigned at leastone buddy while working in the exclusion zone or hot zone. Mien it is not feaaible for two Mrr employees to actas each others buddy, the buddy may be a client (owner's representative), an assigned employee of Mrr'ssubcontractor, an assigned employee of the owner's contractor, preferably but not necessarily a safety trained (24or 40 hours hazardous waste training) person on site, as long as both buddies agree to act as each other's buddyprior to entry to the exclusion or hot zones. Buddies must remain in each other's line-of-sight at all times in Iessboth buddies are in possession of operating walkie-talkies. Mrr's subcontractor will be required to provide a buddywhenever necessary when a Mrr employee is working in the exclusion or hot zones.

A buddy is not required within the same exclusion or hot zone, as long as (1) communication equipment (such aswalkie-talkies) or line-of-sight are used and (2) the buddy can render amsrginc) care if nisdsd. This requires thatthe buddy be prepared (wearing proper personal protective attire) to promptly enter the exclusion/hot zone to renderemergency care if necessary.

7.0 SITE COMMUNICATIONS

11.0 OSHA INSPECTIONS

The following procedures discuss iarr's response to OSHA inspections when: 1) iarr is pria» contractor, or 2) whenanother party including the owner serves as prism) contractor.

11.1 Procedures to be Followed when aarr is Prime Contractor

The procedures listed below are to be followed in the event that an OSNA inspector visits the site, and iarris the prime contractor. The procedures are consistent with iarr's rights and the requirement* for OSHA't

• performance of an inapection.

a) Introduce yourself with your name and title. Titles to choose from include field geologist, fieldengineer, field observer, resident project representative, iarr Project Health and Safety Team Leader,etc. In these first Minutes of orientation, try to ask all the questions. Hold off answering enyadditional questions until you have contacted the Project Manager (see below). If there is More thanone iarr employee on-site, the Most senior iarr employee should act as iarr's en-site representativeuntil the Project Manager is contacted.

b) Ask the OSHA inspector to show you their credentials. Inspect the credentials; the credential! shouldhave a picture of the OSHA inspector. If necessary, ask for the phone number of the OSHA inspector'soffice to confine that this is an OSNA inspector.

c) Ask the OSNA inspector for certification of 40 hour training, and the east recant 8 hour refresher.The OSHA inspector Mav net enter the hot zone, exclusion zone, or DECON area (according to 1910.120)without this training. In addition, the OSNA inspector is required to have the appropriate PPE, asspecified in the PNASP for work zone entry, and the OSHA inspector Mav net enter those work zoneswithout the appropriate PPE. Certification of participation in a Medical surveillance prograei May beoptional for OSHA inspectors, if they don't routinely work on hazardous waste sites.

d) Ask the OSHA inspector what is the purpose of their site visit.

• What type of inspection is this? Coapleint? Follow-up? General Schedule?• What ere the ereec of the site thet the inspector hes come to the site to inspect?• If there was a complaint, ask to see a written copy of the complaint.• what type of monitoring, if any, does the inspector expect to conduct?• If the site is More than a one-hour drive/air flight from iarr's office, ask the OSHA inspector

if they would come back tomorrow to telk to the Project Manager.e) Infer* the OSHA inspector thet you will need to contact the Project Manager since you do not hove the

authority to either grant or limit the inspection. If iarr is the prime contractor, ask the OSHAinspector to weit off-site and not to take any pictures while you are Making this phone call. If iarris not the prime contractor, see paragraph 11.2 below.

f) Call the Project Manager and indicate what you have learned about this OSHA inspection. You hove theright to Make this phone call in private.Since iarr is the prime contractor, the Project Manager should tell you to ask the OSNA inspector toweit off-site, until the Principel-ln-Cherge arrives. Until that time, inform the OSNA inspector thetyou cannot give the inspector pemission to begin the inspection, take any pictures or interview iarremployees. Such permistion can only be granted by the Principal-ln-Charge.

PtOTOTTP\PHASPAPP.93A A-11 Edited: Nay 7, 1993

OPERATING PROCEDURES

g) The Project Manager should in turn try to locate the Principal-ln-Charge, othtr designated Principal^Allan Gebhsrd, larry Nolaather, John Oickson, or Karen Stoller to diaeuas what tarr's response to thisinspection Mill be. Additionally, the Project Manager Mill inform the site owner and if different,our client.

h) Generally, if the site ia within a 1 hour drive or air flight fro* the office, infer* the OSHAinspector that the Principal-In-Charge ia on their way to the site. This is a reasonably tie* periodfor the OSHA inspector to wait, and ask the OSHA inspector to wait off •site. Do not talk unnecessarilyto the OSHA inapactor until the Principal-In-Charge arrives.

<) If the OSHA inspector will not wait for the arrival of the Principal-IrfCharge, call the ProjectManager again and explain the predicament. A conference call should be set up st this tie* for theOpening Conference. The Opening Conference is the first stage of an OSHA inspection.

j) Sooner or later the OSHA inspector will perform) their inspection. Continue site operations so thatOSHA inspector say observe health and safety procedures. It ia net necessary to shut-down operetions,however, all site personnel should be informed that an OSHA Inspection is In progress. Operations e»ybe shut down if participation in the inspection ispedes the progress of the project work. If the OSHAinspector perform air eanitoring, be sure to conduct air Monitoring side-by-side with the OSHAinspector.

k) le courteous, answer the OSHA inspector's questions, and take careful notes.

11.2 Procedures to be Followed when other parties are Prime Contractor.

If another party has responsibility for site control such as the owner or the owner* or client's contractorand they hove granted access to the DMA inspector to conduct the inspection of their employee*, call theProject Manager and explein that the inspection is in process. The guidelines listed above (a through k) stillgenerally apply. The exceptions ere that since site control concerns are the responsibility of the primecontractor, we say not be able to ask the OSHA inspector to weit off-site or deny entry to the site if theydo not have appropriate training docuMntation. There are usually several concurrent inspections conductedby OSHA on a construction site. The OSHA inspector should be asked to wait before alerting the inspectionof sarr's activities until the Principal-In-Charge determines the appropriate course of action.

2.0 CHEMICAL HAZARDS

Site operations My involve handling Materials which are known or suspected to contain hazardous substances.Exposure to these Materials may occur through one or wore of the following routes.

2.1 inhalation; Substances that priMerUy pose an inhalation hazard are those that volatilize easily at aabienttemperatures (20-Z9*C). A rule of tbuab is that substances with vapor pressures greater than that ofnaphthalene (0.06 •» Hg) at ambient temperatures May be considered volatile. Inhalation hazards my existwhen perticulates containing hazardous substances became airborne.

2-2 Sic in/Eve Contact: lam hazardous substances May be absorbed through the skin and be transported to thebloodstream. Many other substances are not absorbed but react with the skin surface causing irritation orburns. Absorption occurs Most readily through open wounds, inflated skin, or through eye contact. Hazardoussubstances noted with the 'skin* notation in TABLE 5-2 (SECTION 5: TOXICITT PROFILE of the PNASP) are knownto be absorbed through the skin.

3.0 SAFETY PROCEDURES ft* PHYSICAL HAZARDS•

Site operations and tasks may involve inherent physical safety hazards. The aafaty procedures for these hazardsare described in the following paragraphs. Site-specific hazards may be discussed in SECTION 1: PROJECT HEALTHAND SAFETY INFORMATION of the »HASP.

3.1 Utilities

Overhead and underground utilities (e.g., electric, gas, telephone. Meter, sewer, drainage, etc.) andassociated pipes in the project work areas oust be located. Underground utilities should be located and a»rkedby the utility owners or site owners before the atart of any intrusive activity. Overhead utilities shouldbe located and where appropriate, protected before the set-up and operation of heavy equipment, such as a drillrigs, cranes, loaders, menlifts, etc.

3.2 Hesw Equipment Operations

Site operations My involve the use of heavy equipment such as drill rigs, backhoes, dozers, loaders, scrapers,trucks, etc. by Barr's subcontractor* or the site owner's contractors. The following information describesadditional safety procedures while working around heevy equipment.

a) Stay within the line-of-sight of the operator at all tie** while working near the equipment. Normaloperation of heevy equipment affects the operator's ability to hoar and to aae all areas around theequipment.

b) Keep a aafe observation distance of at laaat the reach of the backhoe bucket plus 5 feet except whenworking directly with the backhoe operator. If working within roach of operating equipment alwaysalert operator of your position.

c) Avoid walking directly in back or to the side of heavy equipment. Avoid operator blind areas.Understand the direction the equipment is likely to move and how quickly it may make the amneuver.

d) Verify that underground and overhead utilities have bean identified and located.e) le aware of footing and surroundings at all times.f) Do ngj work near equipment that My appear obviously unsafe because of deterioration, missing parts,

obvious defects, or iaproper operation. Do not permit use of such equipment by any of aarr'ssubcontractors if equipment appears to be unsafe.

*«OTOTY»\MU»A»f .93A a-3 Edited: May 7, 1993

HAZARD EVALUATION

g) If heavy equipment and other vehicles share a common roadway, Mrr employees and Mrr's subcontractorsahould be alert to this traffic and yield right-of-way. If working in an ares with congested heavyequipment operations, wear an orange vast. Park in a clear area, not in an area obstructed fromoperator's view.

h) Oo not operate heavy equipment.i) Stay out of reach of cable* or chains which might break while lifting or pulling objects.

3.3 Excavation Entry Procedure

Any entry to an excavation or trench ahould be performed in accordance with the Mrr excavation entryprocedure. All excavation entry should be cleared with an appropriately trained Mrr employee. For excavationentry procedures, please see APPENDIX 6: EXCAVATION ENTRY. If soil samples are required from excavationmaterials, samples should be taken from the backhoe bucket or from the spoils pile, or other nonentry methods,whenever possible.

3.A Lighting

work areas must have adequate lighting for employees to see to work and identify hazards, work should belimited to daylight hours unless artificial lighting is providjd. Mrr employees ahould carry flashlightsin all normally dark areas, such aa confined space*.

3.5 Lifting

Heavy objects, such as pumps and generators, should be lifted with proper lifting techniques, such as usingone's legs to lift rather than one's beck, and preferably by at least two persons. Material handling equipmentto move the object should be used when an object is either too heavy or bulky to move normally without riskof injury.

3.6 Pet

Abandoned buildings on site may be structurally unstable. Roof, ceiling, floors, walkways, and doors may bedamsaid. Hard hats, steel-toed boots and safety glaaaes should always be used when entering those buildings.An initial walk through with a buddy should be conducted in or near any abandoned facility to identify physicalhazards. These types of buildings should be entered only if necessary and may be considered a confined space.

PMTOTTP\PtU$PAPP.9SA

HAZARD EVALUATION

3.7 Electrical Power Hazards

Electrical equipment suit be properly grounded or double insulated and should be inspected prior to uae. Anyelectrical equipment in questionable condition should not be used. Operation of electrical equipment in Metconditions oust be avoided unless equipment and electric service are specifically designed for Mater immersion.

3.8 Energized Equipment

Work on or near energized equipment should not be conducted until the equipment is appropriately locked-out.Appropriate lock-out procedures prevent the equipment from being turned on while a person is working on ornear the equipment.

3.9 Slipping

Slipping on wet, muddy surfaces can be minimized by diverting Hater away from work area, avoiding slipperysurfaces, or by providing a better surface to walk on. such as laying boards on the muddy surface, loots withgood treads or boot covers should be worn if the area is wet or Buddy. Walking in puddles, drilling aud anddrilling additives should be avoided. Clipping on snowy or icy surfaces should be sriniaizad by evoidinj thesesurfaces whenever possible.

3.10 Limitations Pue To Personal Protective Equipment

The use of personal protective equipment s»y limit visibility, hearing, or manual dexterity. In addition,wearing personal protective equipment mey require additional physical exertion of the wearer. Thestlimitations are evaluated during the preparation of the PHASP and should be re-addreesed, as appropriate, priorto performing a particular task.

3.11 Hoise Extremes

Noise exposure mey occur en site from heavy equipment operation, especially while working in the area ofoperating equipment. A general rule of thumb to determine if noise levels are high enough to require hearingprotection is to observe if two persons standing approximately 2 feet apart have to raise their voices toconverse. If conversation cannot occur without shouting, noise levels probably exceed 85 dsA and hearingprotection should be utilized. Hearing protection is available, in the fora of ear plugs, eer muffs, or both,and should be used when working eround heavy equipment.

Thasa materials my ba found in druac. including lab packs, as aithar a solid orliquid. Tha bast pracaution for individuals working at thaw typas of landfills is constant monitoring forionizing radiation using a geiger countar or similar monitoring instruaant. Initial monitoring should baconducted to datact high lavals of radiation where radiation is suspected to ba present. Exposure monitoringis continuously conducted for tarr eaployeea Mhan their TLO badge is worn. If radioactive Mterials arasuspected on sits, protective wasuras will ba discussed in SECTION 1: PROJECT NEALTN AND SAFETY INFORMATIONof the PMASP.

3.13 Momoniiina Kadiation

•arr occasionally uses ground conductivity Mters, such as a Seonics ENS1. The frequency this device generatesis 9.8 kHz. A comparison to the ACS IN TLV indicates that this frequency ia not contained within the frequencyranges of concern.

3.U Heet ttress

Heat-induced occupational illnesses, injuries and reduced productivity occur in situations in which the totalheat load (environa*ntal plus metabolic) exceeds the body's capacities to maintain nonaal body functionswithout excessive (train. Heat stress is defined as the SUB of the heat generated in the booy plus the heatgained fro* the environment Minus the heat loat from the body to the environment. The body's response to heatstress is called heat strain. Tha level of heat stress at which excessive heat strain will result dependson the heat-tolerance of the individual. Certain predisposing factors may reduce an individual's ability totolerate heat stress and ara addressed in SECTION 3.K.I.

Using personal protective equipment may put a worker at increased risk of developing heat stress. Healtheffects may range from heat rash or heat fatigue to serious illness or death. Neat strew is caused by anumber of interacting factors, including environmental conditions, such aa temperature and relative humidity,protective clothing which limits natural heat loss through perspiration, workload, and the individualcharacteristics of the worker.

It is the responsibility of the project team miatiiri to infora the •reject Nwlth and Safety Team Leader ifany of the predisposing factors listed below apply to that individual. This enables the Project Health andSafety Team Leader to monitor the individual if necessary, or use other means of preventing/reducing theindividual's likelihood of experiencing a heat-related illness/disorder.

3.14.2 Prevention of Heat Stress

Prevention of heat-related illness begins with a recognition that hot and/or humid environment* canhave serious iapect on both project personnel end the project itself. In particular, it aust berecognized that work in hot environments can reduce both the quantity and quality of work that fieldteeas can deliver. »y planning for heat-related effect* and building prevent*tive measures into theproject schedule and budget, the iapact of heat on the project end personnel can be minimized.

HAZARD EVALUATION

There are a variety of measures that can be isplesMnted to prevent or reduce the likelihood of,eaployees developing heat stress related illness/disorders. These include fluid and electrolytereplenishment, the provision of shelter froB the sun and heat. Mork schedule adjustment, the use ofcooling devices, acclimatization, heat stress Monitoring, and eepleyee education, as discussed below.

• Fluid and Electrolyte Reeleniahaant; Personnel should drink about 16 ounces of Mater beforestarting work and drink Mater at every break. To encourage Mater consumption, cool Mater anddisposable cups should be made available. The nonaal thirst mechanism is not sensitive enough toensure that enough Mater Hill be drunk to replace lost sweat. When heavy tweeting occurs,personnel should be encouraged to drink awe. Replacing body fluids with an electrolytereplacement such as Gatorade is an option. It is advisable to have Gatorade on site if the airtaapirature is 7D*F or acre and the workers are performing tasks with a moderate to heavy workload in chemical resistant clothing.

• Shelter From The Sun end Heat; Air-conditioned (if possible) or shaded ereas should beavailable for reet periods. Sitting in an air-conditioned truck is an acceptable option. Shadingof work areas is often e practical and economical option.

• work Schedule Adjustment; Scheduling work for oarly mornings and/or late afternoons will avoidthe hottest parts of the day, and reduce the heat stress placed on personnel; rotation ofpersonnel will help reduce overexertion of workers; end, adjusting the work-rest schedule willhelp personnel recover from the effects of heat stress periodically. Frequent short breaks aremore effective in preventing heat Illness than one or two long breaks.

• Use of Coolino Devices! The use of cooling devices like field showers, hose-dawn areas, orcooling vests should be considered for project tasks that involve heavy work loads in chemical-reaistant clothing. Contact the Rarr Safety Staff for information on cooling vests.Acclimatization: Acclimatization is the gradual introduction of workers into a hot environmentto allow their body to physiologically adjust to hot working conditions. Acclimatized individuelsgenerally have lower heart rates and lower body temperatures. In addition, they sweat sooner andmore profusely end even have more dilute sweat (thereby loosing lees electrolytes) thannonacclimatized individuals.Heat Stress Moniterine: Monitoring of the environment or personnel for potential heat stressshould be initiated when the ambient air temperature is 70*F. There ere several Mays to monitorheat stress; measuring heart rete, oral temperature, loss of body weight, and the wet Rulb GlobeTemperature using e Reuter-Stokes RSS 217 or a Queatemp IS Heat Stresa Monitor. Rarr employeesare advised to measure their heart rates as a primary means of heat atress monitoring whanimpermeable protective clothing is worn.

• Eaplovee Education: workers have already been trained to recognize end treat the effects of hoststress during the *0 hour training. Signs, symptoms and treatment of heat stress should bediscussed in project safety meetings. The Ruddy System Mill help in preventing heet stress oncethe employees are trained to recognize the signs end symptoms of heat stress.

3.15 Cold Stress

Fatal exposures to cold have been reported Mhan persons fail to escape from low environmental air temperaturesor from immersion in low temperature water. Hypothermia, a condition in which the body's deep core temperaturefalls significantly below 9B.6*F, can be life threatening. A drop in core temperature to 95*F or lower mustbe prevented.

Air temperature is not sufficient to determine the cold hazard of the work environment. The windchill mustbe considered as it contributes to the effective temperature. The body's physiologic defense against coldincludes constriction of the blood vessels, inhibition of the awaat glands to prevent loss of heat viaevaporation, glucose (fuel) production, and involuntary shivering uTproduce heat by rapid muscle contraction.

•ROTOTYP\F-NAf»AW>.93A B-11 Edited: Nay 7. 1993

HAZARD EVALUATION

The frequency of accidents increases with cold exposures as the body's nerve impulse* slow down, individualsreset sluggishly snd numb extremities make for increased clumsiness. Additional safaty hszsrds include ice,snow blindness, reflections from the snow, and possible skin burns from contact with cold mstsl.

There sre certsin predisposing factors that make en individual sore susceptible to cold stress. It is theresponsibility of the project teem aimtiin to infer* the Project Health and Safety Teem Leader if any of thepredisposing factors listed below apply to that individual. This enables the Project Health and Safety TeemLeader to monitor the individual if necessary, or use ether means of preventing/reducing the individual'slikelihood of experiencing a cold-related illness/disorder.

3.15.1 Predisposina Factors

Predisposing factors that will increase an individual's susceptibility to cold stress sre listed below.

Dehydration - The use of diuretics and alcohol, and diarrhea can cause dehydration. Dehydrationreduces blood circulation to the extremities.

• Fstigus during physical activity - Exhaustion reduces the body's ability to contract blood vessels.This results in the blood circulation occurring closer to the surface of the skin and the rapidlose of body heat.

• Age • Some elderly end very young individuals say have en impaired ability to sense cold.Alcohol consumption - Alcohol dilates the blood vessels near the skin surface resulting in bodyheat loss.Sedative drugs - Sedatives may interfere with the transmission of impulses to the orein therebyinterfering with the body's physiological defense against cold.

• Poor circulation • Vasoconstriction of peripheral vessels reduces blood flow to skin surface.• Heavy work load - Heavy work loads generate metabolic heat end make en individual perspire. If

perspirstion is absorbed by the individual's clothing end is in contact with skin, cooling ef thebody will occur.

• The use of PPC • PPC usage which traps swast inside the PPC may increase en individuel'ssusceptibility to cold strass.

• Lack of acclimatizstion - Acclimatization, the gradual introduction of workers into a coldenvironment ellows the body to physiologically adjust to cold working conditions.

• History of cold injury - Previous injury due to cold exposures may result in increased coldsensitivity.

3.15.2 Prevention of Cold Stress

There sre s variety of measures that can be implemented to prevent or reduce the likelihood ofemployees developing cold related illness/disorders. These include acclimatization, fluid andelectrolyte replenishment, eating a well •balanced diet, weer ing wens clothing, the provision of shelterfrom the cold, thermal insulation of metal surfaces, adjusting work schedules, and employee education.

Acclimatization; Acclimatization is tha gradual introduction of werkars into a cold environmentto allow their body to physiologically adjust to cold working conditions. However, thephysiologic changes are usually Minor and require repeated uncomfortably cold exposures to induce

Fluid and Electrolyte Replenishment: Cold, dry air can cause employees to lose significantamounts of Meter through the akin and lungs. Dehydration affects the flow of blood to theextremities and increases the risk of cold injury. Wans, sweet, caffeine-free, nonalcoholicdrinks and soup are good sources to replenish body fluids,Eating a well-Balanced Diet; lestrictad diets including lew-salt diets can deprive the body ofelement* needed to withstand cold stress. Eat high energy food throughout the day.ware. Clothing; It is beneficial to maintain air apace between the body and outer leyers ofclothing in order to retain body haat. However, the insulating effect provided by such air spacesis lost when the skin or clothing is wet.Work Schedule Adjustment; Schedule work during the warmest part of the dey if possible; rotatepersonnel; and, adjust the work schedule to enable employees to recover from the effects of coldstress.

The parts of the body most iaportant to keep warm are the feet, hands, head and face. As much ss 40Xof body hest can be lost when the head is exposed.

• Hecommended Clothing includes;

Inner layers (t-shirt, shorts, socks) should be of thin, thermal insulating, nonmoistureabsorbent materiel, moisture Kicking, such as polypropylene.wool or thermal trousers. Denim is not a good protective fabric since it absorbs moisturevery Met I.

Felt-lined, rubber-bottomed, leather-topped boots with a removable felt insole is preferred,wool socks with polypropylene inner socks. Consider winter boots one half size larger thanregular size to acconmodate thick socks.wool shirts/sweaters should be worn over inner lever.A wool cap is good head protection. Use e liner under s hard hat.Mittens are better insulators than gloves, wool liners for either mittens or gloves.Face masks or scarves are good protection against wind.Tyvek/polycoated tyvek provide good wind protection.wear loose fitting clothing, especially footwear. Consider winter boots s half size largerthan regular shoes to accommodate thick socks.Carry extre clothing in vehicle. Change out of wet clothes or socks.

Provision of Shelter freai the Cold; Shelters with heaters should be previdad for the employees'rest periods if possible. Sitting in e heated vehicle is a viable option. Care should be takenthat the exhaust is not blocked and that windows are partially open to provide ventilation.Thermal Insulation of Metsi Surfaces; At temperatures of 30*F or lower, cover metal tool handleswith thermal insulating material if possible.

PROTOTYP\PNASPAPP.93A C-7 Edited: Mey 7, 1993

PPB PROGRAM

11.0 PPE LIMITATIONS

Selection of chemical-resistant clothing should be performed by personnel trained in evaluation of the clothing andits limitations. Consideration of the following factors and limitations is generally considered in the selectionof PPE described in the PNASP.

• Not all materials protect egeinst all chemicals and chemical combinations, and not all materials provide ebarrier for prolonged exposure periods. Since moat contaminated soils/water are mixtures of hazardoussubstances, there is limited permeation data available for those mixtures. Selection should be meow forclothing offering the widest range of protection against the chemicals expected on site.

• Protective clothing is generally nonporous and is designed to prevent skin exposure to hazardous substances.Consequently, the nonporous nature does not allow for sufficient cooling of the body through sweating and otherheat release body functions. Temperature extremes will be considered in the PHASP when selection of PPE ismade, and suggestions will be made on duration of use of PPC, and rirnmmendad break schedule es appropriateto weather conditions. Guidelines for working in PPE during temperature extremes is discussed inAPPENDIX •: HAZARD EVALUATION.

• In cold weather, the polymer coating on some disposable clothing may become inflexible and teer more eesily.• The use of boot covers to protect footwear from contamination may increase the potential for slipping hazards.

Other limitation* to consider are:

Ability of material to withstand the physical stress of tasks (e.g., boot covers torn by walking on sharpobjects).

• Degree to which protective clothing may interfere with a worker's ability to perform tasks (e.g., full*facepiece respirator interferes with ability to read survey scope).

1.0 SCOPE

•err has established this personal protective equipment (PPE) program for hazardous Haste operations to provideguidelines and procedures that enable employees to moat effectively use the PPE provided to them. Discussion ofprotective equipment normally used by tarr personnel, except respiratory protection, is provided in this section.Respiratory protection is described in APPENDIX E: RESPIRATOR PROGRAM.

2.0 PPE SELECTION

Levels of personal protection vary according to the activity being conducted and the hazards that may be encountered.Personal protective equipment selection is made on the basis of site-specific chemical and physical hazards. TheU.S. EPA terminology for protective equipment trill be used: Levels A, 1, C and D. Within each level, there mey bevariations on the specific PPE used and are designated as 01, 02, 03, 04. C1, C2, C3, C4, etc. A brief descriptionof the levels of protection that may be required is provided below. Levels of protection for a particular projectwill be specified in SECTION 1 of the PNASP.

2.1 Level 0

Level D protection should be used when e hazardous atmosphere is not present nor is expected based on plannedwork ectivities. Level D protection is designed to offer eye and akin protection. Level 0 does not provideprotection from inhalation exposure to hazardous substances. Sub-levels within Level 0 (01, 02, 03, W) aredesigned to adjust the level of skin and body protection to the appropriate site conditions.

2.2 Level C

Level C protection is designed to offer eir purifying respiratory protection in addition to bodyprotection to a comparable sublevel in Level 0, and will be used when:

• the types of air contaminants have been identified, an air-purifying respirator (APR) that can removethe contaminants is available, the air contaminants have adequate warning properties, oxygen levelsare sufficient, and the criteria for the use of an APR have been met (APPENDIX E: RESPIRATOR PROGRAM);

• concentrations of airborne organic compounds in the breathing zone ere 5 ppm (benzene equivalent) abovebackground for a period of 10 minutes with a ceiling of SO ppm (benzene equivalent), or above projectspecific action levels; or

• concentrations of contaminate particulates which may become airborne fn the breathing zone are greaterthan established action level for those contaminates.

PPS PROGRAM

Sublevels within Level C (C1, C2. C3, C4) art designed to adjust the loval of skin and body protectionappropriate to *ite conditions with a particular laval of respiratory protoction. Respirator saloctionis basod on the typas of inhalation hazards prosant on tha sita. When Level C rospiratory protectionis required, a full face or hatf-Bask air-purifying respirator with Nigh Efficient Paniculate Air(HEPA) filters, or organic vapor/acid gas cartridges, or chemical specific cartridges, or a coatoinationof both filters and cartridges, or a canister will be used. The PNA*P designates the appropriatecombination in SECTION 1: PROJECT HEALTH AND SAFETY INFORMATION. APPENDIX E: RESPIRATOR PROGRAM

describes respirator usage guidelines in greater detail.

2.3 Level i

Level • protection is designed to offer supplied air respiratory protection in the fona of a self-contained breathing apparatus (SCM) or supplied air (SA) through an air line and Mill be used when:

• concentrations of total airborne organic coapounds exceed 50 ppa of unknown organic* in the breathingzone, or project specific action levels; orconcentrations of hazardous substances in the air are iaMdiately dangerous to life and health (IDLN)or above the sax i BUM use liaiit of an APR with full-face eask; or

• oxygen deficient or potentially oxygen deficient atsnspneres {19.S percent or leaa) are possible; orconfined space entry requires Level • protection.

Level B protective equipment Mill consist of all equipment specified for Level C protection except thefull-face APR equipment Mill be replaced Mith self-contained breathing apparatus (SBA), or a suppliedair (SA) systeai Mith an egress bottle, if IDLH conditions are possible.

Use of Level I requires that buddies actually acccapany each other and, in addition, at least one otherperson mat be at Level • and available as back**?, ready to provide eaarusncy assistance.

2.4 Level A

Level A protective equipatent should be Morn Mhen the highest level of respiratory, akin, and ayeprotection is nssdsd. larr does not expect to Mork on projects involving this level of protection.

Personal protective equipaent (PPC) selected to protect against potential hazards is described in TABLE C-1 •PERSONAL PROTECTION LEVELS. These protection levels e»y be Modified (upgraded or downgraded) by the iarrProject Health and Safety Tea* Leader depending on specific sita conditions, equipment configuration, statusor phase of site activities, air Monitoring results and previous experience. The level of PPC used shouldbe reevaluated for appropriateness upon the first indication of suspected hazardous substances through thedetection of odors fro* exposed soils/fluids, appearance of oiliness in soils, or unnatural soil discoloration.

They mey also be worn inside outer gloves when there is e greater likelihood of contactwith Mterials known or suspected to contain hazardous substances to provide protection againstdegradation/leakage of the outer gloves.

Outer gloves of nitrile, vinyl, neoprene, butyl, or viton (11-14 mil thickness) will be worn whenhandling materials known or suspected to contain hazardous substances or when a serious dermal (skin)hazard exists. Selection of glove type is based on degradation and permeability of glove Mterial toexpected contaminants on the site. In cold weather, insulated orange vinyl-coated gloves (monkey-grips) My be worn as outer gloves.

One pair of surgical gloves (nitrile, letex) is required when handling containers that contain samplesknown or suspected to contain hazardous substances. A second peir of eurgical gloves is required whencollecting the sample known or suspected to contain hazardous substances from split spoon sampler orbailer or when performing headspsce analysis. This second pair (outer layer) should be replacedimmediately after handing or collecting the seaple. This outer lever should consist of s thickerMterial (nitrile, neoprene) when handling high concentrations of hazardous substances or Mterialsknown or suspected to contain coal tar or PM or when collecting a sample from the beckhoe bucket.

4.0 WORK TASK DURATION

In selecting personal protective equipment, the estiMted duration of job tasks and project duration is considered,in addition to other considerstions. Protective equipment is chosen that will provide protection for s full workshift, or for the duration of the task to be accomplished. If site conditions are such that protective equipment

PPS PROGRAM

cannot provide adaquatt protection for tho duration of the task, several factors are considered to determineappropriate work task duration, including:

Clothing/glove penssation and penetration rates for cheatcaIs• Respirator/filter cartridge capacity and In eatthrough tie*• Aabient tospersture and weather conditions• Integrity of the tyvek, boot covers, and gloves.

These factors are incorporated into the selection of personal protective equipasnt, and will be addressed asappropriate in the PHASP. In addition, as soon as the integrity of any PPE is coaproaisad, the work task shouldstop until the PPE can be replaced.

5.0 MAINTENANCE AND STORAGE

Nondisposable protective equipasnt such as hard hats, boots, and safety glasses will be decontaainated, if necessary,prior to leaving the project site. Respirators will be decontaainated after each use. Most disposable clothingsuch as tyvek. boot covers and outer gloves are discarded at the and of a work shift. If, after inspection, anddecontaaination procedures, it has bean determined that the clothing aay be reused, these itaas aay be storedappropriately until re-used. All used disposable clothing will be discarded upon daaabiliution froa a site.

6.0 DECONTAMINATION AND DISPOSAL

Decontaaination and disposal procedures for personal protective equipasnt are covered inAPPENDIX 0: DECONTAMINATION.

7.0 TRAINING AND FITTING

All Mrr eaployees with 24- and 40-hour training have been trained in the use and selection of.personal protectiveequipasnt, and have been provided hands-on training on using PPC. Cadi iarr eaployee tilth 40-hour training has beanfit-tested with a respirator according to the procedures outlined in APPENDIX Is RESPIRATOR PROGRAM. All iarr fieldeaployees (regardless of training level) will be fitted far and provided with steal-toad boats, hard hat, and safetyglasses with side shields (and safety sunglasses, if necessary). A large inventory of protective clothing, gloves,and boot covers is aaintainad in various sixes. Each saployee is encouraged to try on the various sixes to determinethe best fitting sixe of all personal protective equipasnt.

8.0 DRESSING/REMOVAL PROCEDURES FOR PERSONAL PROTECTIVE EQUIPMENT

Clothing required as protection froa exposure to hazardous substances will be put en at the site before entry intothe exclusion xons. If protective outer garaants are necessary, the suit (tyvek, poly-coated tyvek, saranex, etc.)will be put on first, followed by boots, boot covers and gloves.

1.0 SCOPE

Personal protective equipment (PPE) and Monitoring aquip«ant aust either be decontaminated or properly discardedupon exiting from the exclusion zone. This practice prevents cross-cantaaination to claan araas. All larr aaployeesand Barr's subcontractors aust enter and axit the exclusion zone through the decontamination (DECON) zone.

2.0 DECONTAMINATION METHODS

Decontamination a»thods should involve: physically removing contaminants, neutralizing contaaiinants, or removingcontaminants through a combination of both physical and chemical means. The types, physical states, andconcentrations of contamination present Mill determine the feasibility of DECON and appropriate method ofdecontamination.

3.0 PROCEDURES

A step-by-ctep representation of decontamination procedures and ninmmenJiJ locations for decontamination stationsfor Levels D, C, and I is provided in FIOURE D-1: DECONTAMINATION PROCEDURES in this section and in SECTION 4 ofthe PNASP. The Project Health and Safety Team Leader will ami tor decontamination procedures and may modify. Ifappropriate, to suit site conditions and specific protective levels in use. General standard operating proceduresto be followed are:

Minimize contact with contaminants in order to minimize the need for extensive decontamination.• Sanpling/monitoring equipment, when feasible, should be enclosed in plastic bags to prevent contamination and

the need for DECON.Decontamination solution of soap on other detergent, such as trisodiun phosphate (TSP) end water should beused.

• Cloves, boot covers, and disposable outer clothing should be rolled down with the insides out and discardedin appropriate containers.

4.0 EQUIPMENT DECONTAMINATION

Air monitoring equipment will be decontaminated before leaving the site. Mile the decontamination procedures shouldbe appropriate for the type and concentration of site contaminants expected, the selected procedure should not bedamaging to the monitoring equipment. Generally, wiping the equipment with a damp cloth or cloth soaked in a mildsoap solution is sufficient to remove most contaminants. If solvent cleaning or more rigorous cleaning techniquesere required, the Equipment Maintenance Technician should be consulted.

PROTOTYP\PHASPAPP.93A D-1 Edited: Nay 7. 1993

DfCONTMtlHATION

Other site equipment such as vehicles, soil, or other sampling equipment should be decontaminated prior to leavingthe site. Vehicle decontamination at minimum should consist of steam or pressure washing tires. Depending uponsite conditions, the use of solvents or more extensive pressure washing may be necessary. Site-specific equipmentdecontamination procedures, if required, are discussed in the Nealth and Safety Plan.

5.0 WASTE DISPOSAL

•err personnel on site Mill determine whether protective clothing is contaminated, in which case it Mill remain onsite for future disposal by the owner. Personal protective clothing may be considered contaminated when the levelof contamination present meets hazardous waste criteria. Clothing which does not carry levels of contaminationsufficient to warrant this categorization may be disposed of as garbage. ATTACHMENT D-1 should be consulted forfurther guic

It is unlikely thet any nonvisible residue adhering to disposable protective clothing would be present at the levelsrequired to meet hazardous waste criteria. Protective clothing that is not visibly dirty Mill therefore be placedin garbage begs to be disposed of as garbage. All visibly dirty protective clothing Mill be placed in drums orsecured plastic begs to remain on site or otherwise disposed of as determined in the work scope of the project.

6.0 MANAGEMENT AND DISPOSAL OF DECONTAMINATION SOLUTIONS AND OTHER INVESTIGATION-DERIVED HASTES

Decontamination solutions and other investigation-derived wastes must be decontaminated or be properly disposed.In determining if a particular management disposal option is appropriate, the following should be considered:

• the contaminants, their concentretions, and the total volume of decontamination solution;• media potentially affected (e.g., groundwater, soil) under management options;• location of the nearest population(s) and the likelihood and/or degree of site access;• potential exposure to workers; end• potential for environmental impacts.

The U.S. EPA has releaaad a fact sheet (January 1992) summerizing appropriate methods for managing decontaminationsolutions and other investigation-derived waste. ATTAOMENT D-1: GUIDE TO MANAGEMENT OF INVESTIGATION-DERIVEDWASTES contains the information in the U.S. EPA fact sheet which has bean retyped to improve its legibility.

7.0 SHOWERS AND CHANGE ROOMS

CERCLA field investigation activities (e.g., remedial investigation/feasibility studies and remedial designs) may result inthe generation of waste materials that may pose a risk to human health and the environment. These investigation-derived wastes(IDW) may include drilling muds, cuttings, and purge water from test pit and well installation; purge water, soil, and othermaterials from collection of samples; residues (e.g., ash, spent cartoon, well development purge water) from testing of treatmenttechnologies and punp and treat systems; contaminated personal protective equipment (PPE); and solutions (aqueous or otherwise)used to decontaminate nondisposable protective clothing and equipment. The management of IDW must ensure protection of hunan healthand the environment and comply with (or waive) regulatory requirements that are applicable or relevant and appropriate requirements(ARAR). This fact sheet presents an overview of possible IDW management options, discusses the protectiveness requirements andARARs associated with these options, and outlines general objectives established for IDW management under Superfund.'

The general options for managing IOU (see Highlight 1)are collection and either (1) immediate disposal or (2) sometype of interim management. Interim management may includestorege or other temporary measures. As discussed below, thespecific option selected wi l l depend on the type of wasteproduced, its relative threat to human health and theenvironment, and other site-specific conditions.

IDW MANAGEMENT REQUIREMENTS

When managing IDW, site managers are required to choosean option that: (1) is protective of human health and theenvironment and (2) complies with (or waives) ARARs, asdescribed below.

Protectiveness

In determining if a particular management/disposal optionis protective, site managers should consider the following:

The contaminants, their concentrations, and total volumeof IDW;

• Media potentially affected (e.g., ground water, soil)under management options;

• Location of the nearest population(s) and the likelihoodand/or degree of site access;

• Potential exposures to workers; end

• Potential for environmental impacts.

As a general rule, it will be necessary to use bestprofessional judgment, in light of the site-specificconditions, to determine whether an option is protective ofhuaan health and the environment, for example, a site managermay determine that storing IDW temporarily until the finalaction or returning IDW to its source is protective, based onknowledge that the meterial poses low risk and/or that thefinal action will address any risks posed by the wastes andthere will be no unacceptable risks in the interim.

Alternatively, If the site includes or is nearresidential areas, the site is unsecured, and/or contaminantsappear to be present at unacceptable levels, it may not beprotective to return excavated sail to the source. StoringIDW in containers in an en-site, secure location, or sendingit off site immediately may be more appropriate.

Site managers also need to consider the potential effectsof IDW management-related activities on environmental media.For example, pouring contaminated purge water on the groundaround a well may not be prudent, because such an action couldmobilise any hazardous constituents present in the soil orintroduce contaminants into clean soil.Compliance with ARARs

Remedial Investigation/Feasibility study (RI/FS) andRemedial Design (RD) actions must comply with ARARs 'to theextent practicable, considering the exigencies of thesituation* (MB, 55 FR «756, emphasis added); therefore, ftgenerally Mill not be necessary to obtain a waiver if an ARARcannot be attained during these actions. If a site managerdetermines that, based on site-specific factors, compliancewith an ARAR is practicable but an ARAR waiver is warrantedfor an RI/FS or RD action, an interim action waiver may beavailable if the final rsmei*> will attain the ARAR. An actionmemorandum should be prepared for the waiver, the state givenan opportunity to comment, and the decision document placedin the administrative record.

Potential ARARs for IDU at CERCU aitaa includeregulations under the Resource Conservation and Recovery Act'RCRA) (including both Federal and State underground fnjaction

itrol (UIC) regulations), the Clean Water Act COM), the,.««n Air Act (CAA). the Toxic Substances Control Act (TSCA).and other State environmental laws. MOM these variousrequirement* may direct or influence IOW management decisionsis described below.Resource Conservation and Recovery Act (RCRA). Certainsection* of the RCRA Subtitle C hazardous waste regulations(e.g., land disposal restrictions and storage restrictions)My be ARARs for IDU should RCRA hazardous waste be identifiedat a site. (Note that RCRA may be relevant and appropriateeven if the IDW is not a RCRA hazardous waste.) A waste Ishazardous under RCRA if it is listed as such in 40 CFR 261.31• 261.33 or if it exhibits one of four characteristics!fgnitability, corrosivity, reactivity, or toxicity.

Site Managers should not SSSUM that a waste consideredto pose a potential risk at a CERCU site is a listed orcharacteristic RCRA hazardous waste. Until there is positiveevidence (records, test results, other knowledge of wasteproperties) that the IOW is a RCRA hazardous waste, site•onagers should manege it in e protective earner (but notnecessarily in accordance with Subtitle C requirements).•usine** records or facility processes should be examined todetermine whether RCRA listed wastes were generated and arepresent in the IOW. For characteristic wastes, site managersshould rely on testing results or on knowledge of thematerial's properties. If best professional judgment andavailable information indicate that, for protectivenessreasons (or because RCRA requirements are relevant andappropriate). IOW is best mensgid as a "hazardous waste*menigimint in accordance with Subtitle C requirements isprudent, regardless of whether it is known to be a RCRA waste.

If aqueous liquid IOW is considered a RCRA hazardous^ate, the site manager should determine whether the DomesticSewage Exclusion (DSE) applies to the discharge of that IOWto a POTW. The RCRA DSE exempts deem tic sewage and anymixture of domestic sewage and other wastes that passesthrough e sewer system to a fOTW for treatment fromclassificstion a* s solid waste and, therefore, as e RCRAhazardous waste (40 CFR 261.4).

• Land Disoosel Restrictions

If IDU is determined to be a RCRA hazardous waste andsubject to the land disposal restrictions (LORs), 'landdisposal' of the IDW will be prohibited unless specifiedtreatment standards are met (see Superfund LOR Guides *5 and•7, Determining When LDRs Are Applicable to CERCLA ResponseActions and Determinina When LDRs Are Relevant and Appropriate

9347.3-«to CERCLA Rest OSWER Directive •OSFS9347.3-OBFS, June 1989 and December 1989 and the K». 55 FR8759, March 8. 1990). 'Land disposal* occurs when wastes fromdifferent AOCs are consolidated into one AOC; when wastes aremoved outside en AOC (for treatment or storage) and returnedto the same or a different AOC; or when wastes ere excavated,placed in e separate hazardous waste management unit such asan incinerator or tank within the AOC, and then redepositedinto the AOC.

Storing IDW in a container (*a portable device in whicha material is stored, transported, treated, disposed of, orotherwise handled* (40 CFR 260.10)) within the AOC and thenreturning it to its source, however, jj allowable withoutmeeting the specified LOR treatment standards. Under thedefinition of "hazardous waste management unit* (40 CFR260.10). EPA states that *a container alone does notinstitute e unit; the unit includes the containers and theand or pad upon which they are pieced.* Therefore, returningIOW that has been stored in containers (not tanks or otherRCRA- regulated units) within the AOC to its source does not

constitute land disposal, as long as container* are notmanaged in such a manner as to constitute a RCRA storage unitas defined in 40 CFR 260.10. In addition, saneling ano directreplacement of wastes within an AOC do not constitute landdisposal.• Storage

Subtitle C outlines the storage requirements for RCRAhazardous wastes. Under RCRA. "storage" is defined as "theholding of hazardous waste for a temporary period, at the endof which the hazardous waste is treated, disposed of, orstored elsewhere" (40 CFR 260.10).

On-aite Superfund actions are only required to complywith the substantive standards of other laws (see 40 CFR300.5, definitions of applicable or relevant and appropriaterequirements). Superfund sites are also exempt from permitrequirements under CERCU 1121 (e). Therefore, site managers•re not required to comply with administrative requirementstriggered by RCRA aterage deadline* (e.g., contingencyplanning, inspections, recordkeeping). Generally equivalentadministrative activities are undertaken at Superfund site*,however, under existing Superfund managmeent practices.

Site managers storing known RCRA hazardous waste mustcomply with the substantive, technical requirements of 40 CFRParts 264 and 265 Subparts I (containers), J (tanks), and L(waste piles), to the extent practicable. (See Highlight 2for a sumsery of theae technical requirements for eech typeof unit). In addition, the ground-water monitoringrequirements of 40 CFR Ports 264 and 265 Subpart F arepotential ARARs, and to the extent they are determined to beARARs at a site, they should be attained to the, extentpracticable (or waived). (In many cases, ground-watermonitoring conducted during the RI/FS will provide protectionequivalent to the Subpart F requirements.)

(NOTE: under the LORs, restricted RCRA hazardous wastemay not be stored at a aite unless the storage is solely forthe purpose of accumulating sufficient quantities of the wasteto facilitate proper disposal, treatment, or recovery (see 40CFR 268.50). generally, storing IOW until a final disposaloption is selected in a Record of Decision (ROD) andimplemented during the remedial action is allowable storageunder the RCRA LOR storage prohibition.]

• Recerdkeeeina and Manjf«ttino

If hazardous wastes are sent off site, the site managermust comply with both administrative and substantive elementsof the RCRA generator requirement* of 40 CFR tort 262 and LORnotification and certification requirements of »art 268. (Forexample, a site manager must prepare an LOR notification andcertification when restricted waatea are sent off site to aland disposal facility.) These standards include requirementssuch as manifests for shipping waste that liat all hazardouswaste listings and characteristics applicable to the waate(aee 40 CFR 262.11). packaging and transport requirements, andrecordkeeping requirements.

If the LORs ere applicable, the following informationshould be collected and available before the removal of wastesto an off-aite disposal facility: EPA hazardous wsste number,COR treatment standards, manifest number for the westeshipment, and waste analysis data.• undereround Injection Control (UIC) Program

under the UIC regulations, RCRA hazardous wastes may beinjected into Claaa I permitted wells. In somehazardous liquids, such es extracted ground water fnand treat operations, may be injected into a Class IV UICwell. For example, ground water contaminated with RCRAhazardous wastes may be injected into Claas IV permitted

In addition, EPA hasadopted e policy for Superfund wastes shipped out of Statethat written notification should be provided to receivingStates (OSWER Directive 9330.2-07, September 14, 1989).

GENERAL OBJECTIVES FOR IDW MANAGEMENT

In addition to tho two requirements of protect {venose andalienee with ARARs u tho extant practicable (on aite) oralienee with applicable law (off aite), CM has identified

two general objectives that Superfund site Managers shouldconsider when managing IDW: (1) ainiaization of IOWgeneration; and (2) amnsgmeant of IDW consistent with thefinal rsaidy for the site. The extent to which themeobjectives can be achieved is highly dependent on site-specific circumstances.IDW Minimization

Site aanagsri should strive to ainiaita the generation ofIDW to reduce the need for special storage or diapoaalrequirements that aay result in substantial additional costsyet provide little or no reduction in aite risks relative totho final reaadiel action. Generetion of IDW eon be ainiaizedthrough proper planning of all remedial activities that aaygenerate IDW. aa well as through use of screening Informationfrom the site Inspection. The potential problems of emnegln, -IDW ahould be a factor in choosing an investigativeSite asnegers aay wish to consider techniques

Attachamnt D-1

replacing solvent-based cleaners with aqueous-based cleaners•for decontamination of equipment, reuse ef equipment (utter*it can be decontaminated), limitation ef traffic between clean4 hot zone*, and drilling Methods and aaapling techniquesjt generate little waste. Examples of such techniques

include using gridding techniques to Minimize the number oftest pits or using soil borings instead of test pits.Alternative drilling and subsurface stapling wthods mayinclude the use of small diameter boreholes, aa wall asborehole testing Mthods such as a core panetroMtar insteadof coring. Site Managers should also be careful to keephazardous wastes separate fro* nonhazardous wastes.Haneeement Consistent with final Remedy

Most IOW (with the exception of nonindigenous IDW)generated during the course of an investigation are intrinsic•learnt* of the site. If possible, IDW should be consideredpart of the site and should be Managed with other wastes fro»the site, consistent with the final roMedy. This will avoidthe need for separate traatMent and/or disposal arrangeMants.

Because early planning for IDW ManageMant can preventunnecessary costs and the use of treatment or disposalcapacity, IDW ManagaMent should be considered as early aspossible during the reMedial process. A key decision to beMade is whether the weste will best be treated/disposed ofiMMdiately or addressed with the final reMedy. If addressedwith the final remedy, IDW voluaes should be considered in thefS. In addition, when IDW is stored on site, it should beManaged as part of the first reMedial action/operable unitthat addresses the affected Media.

SELECTION OF IDW DISPOSAL OPTIONS

The following sections present the Agency's prasuBptionsfor IDW amnagsmint that have been established based on thewe considerations. The actual option selected should bej*ed upon best professional judgment and should take into

account the following factors:

• The type end quantity of IDW generated (sludge/soil.aqueous liquid, nonindigenous IDW);

• Risk posed by Menaging the IDW on site (e.g., based onsite access controls, contaminant concentrations);

• Compliance with ARARs, to the extent practicable (onsite;;

• IDW Minimization; and

• Whether the final reMedy is anticipated to be an off-siteor on-tit* reMedy (or this information is unknown) andwhether tow can be Managed consistent with the final

Off-site Final Remedies

If a site manager believes that the final rmmsay willinvolve off-site disposal of wastes, EPA's presumption is toMenage the low as part of the remedial action addressing thewaste/medium. Thus, until the final action, the IDW may bestored (e.g., drvmmmd, covered weste pile) or returned to itssource. However, the Management option selected should alsotake into account any protectiveness concerns, ARARs, andother relevant site-specific factors (e.g.. weather, storagespace, and public concern/perceptions).

There are several potential reasons why it May beadvisable to store IDW until the final action. First, because•stes at the site will be shipped off site eventually.•turning IOU (especially sludges and soil) to its sourcejuld require that it be excavated again. Thus, site Managers

amy consider it practical to containerize IDW as soon as it

la generated. Second, storing IDW in containers May be moreprotective than returning it to its source. Third, becauseoff-site actions may trigger such requirements as the LDRs.temporary atorage will eliminate the need to meet tneseadditional requirements until the final remedy.

In seme cases, circumstances may lead site managers tochoose to return the IOW to Its source. This amy beappropriate If it is determined that returning IDW to thesource is protective and that storage at the site is notpossible or practicable (i.e., given State or communityconcerns). In other cases, long-term storage may not beprotective, and immediate off-site disposal may be a betteroption.

Example; A aite involves volatile organic «CRAhazardous wastes that will likely be sent off sitefor final treatment and disposal. Site conditionsare such that temporary storage of IDW is consideredprotective until the remedial action begins.••cause off-site disposal will trigger ROM disposalrequircMants such as the LDRs and immediatecontainarization would be More protective thanradapositing into the source area at the time ofsampling, the site Manager decides to containerizethe IOW (and comply with ICXA substantive technicaltank and container standards) until the final actionfa initiatad.

On-siteLocation)

of waatee is likely to occur onpresumptions vary depending on the type

finalsite, theof IOU produced.Sludge/soil

Generally, the Agency expects sludge or soil IOW will bereturned to its source if short-term protect iveness is not anissue. The reason behind this presumption is that IDW thatmay pose a risk to human health and the environment in thelong term will be addressed by the final action. Storage ofICXA hazardous IDW in containers within the AOC prior toreturning it to the source will not trigger the LDRs, as longas the containers are not amnagsrt in such a way as toconstitute a ROM storage unit as defined in 40 CFR 260.10.Therefore, it may be possible to store IDW temporarily beforeredisposing of it. However, EPA believes that, in many cases,returning sludges and soils to their source immediately willbe protective and will avoid potentially increased costs andrequirements associated with storage. Site-specif ic decisionson how to manage sludge and soil tow may ultimately vary fromthe presumption based on protectiveness, ARARs, and/or

3.0 RESPIRATOR SELECTION

Respirators w i l l be selected based on the types of hazards present on sites covered by the aarr Health and SafetyPolicy Manual. Factors considered when determining Mhich type of respirator to use are:

• Conteminent level: Mhen the suspected exposure level e»y be greater than the action level determined in thePHASP. The contaminant level must be known if air-purifying respirators are to be used.

• Toxicity of hazardous substance. The identity of the hazardous substance must be known if air-purifyingrespirators are to be used.

• Length of enticipsted exposure to hazardous substance.• Potential for increase in exposure levels.• Presence of other hazardous substances.• When hazardous substances cannot be identified.

• Monitoring method used to determine hazardous substance.

The following limitations apply to use of air-purifying respirators:

• Contaminants must be known.• There must be et least 19.5 percent oxygen.• The atmosphere must not be immediately dangerous to'life or health (IDLN).• Contaminants must have good warning properties.• Atmosphere must be monitored continuously.• Filter/cartridge media must be appropriate for contaminants.

3.1 Respiratory Level of Protection

The PMASP will describe the level of respiratory protection that Mill be necessary for work on sites coveredby the Barr Health and Safety Policy Manual. These levels are:

Level D; No respirator required. Emergency life support apparatus (ELM) optional.Level C; Full face or half face air-purifying respirator with • fitter/cartridge ia required. A full face

air-purifying respirator with a canister may be substituted. ELM may be required.Level B; Self-contained breathing apparatus (SCSA)/supplied air respirator is required.Level A; In the event that Barr employees are required to work at Level A protection, additional special

training and equipment Mill be required. ELM may be required.

4.0 PROJECT SITE SURVEILLANCE

Personal and area air monitoring is done to determine the level of hazardous substances to which personnel may beexposed. Monitoring is continued on a regular basis to determine if an upgrade to Level C or Level B respiratoryprotection is necessary. Monitoring frequency is specified in SECTION 1 of the PNASP.

5.0 TRAINING

All employees covered by the Barr Health and Safety Policy Manual are trained in the proper use of respirators andtheir limitations during the initial (40 hour) training program. Additionally, they are trained on an individualbasis when they are fit tested in the Barr safety equipment room. This training may be reviewed as necessary.Training provides the user the opportunity to:

• Handle the respirator.

Have the respirator fit properly (qualitative fit-teat). Conditions such aa baard growth, sideburns and templepieces on glasses may prevent a good face aeal and cannot be worn by Barr employees using a respirator.

• Test the fscepiece-to-face aeal with a negative and positive pressure fit test.• wear the respirator in normal air for a familiarity period.• Wear the respirator in a teat atmosphere that contains nontaxic irritant smoke.• Be challenged while wearing the respirator, with a test atmosphere by performing simple exercises and reciting

the **ainoow Passage*.

This training also covers proper use of a respirator, assembly and breakdown of respirator psrts. maintenance andrepair, and proper atorage procedures.

RSSPIRATOR PROGKAH

6.0 nan* USE OF RESPIRATORS

There is a specific sequence of procedures that must be followed to ensure a good respirator fit. The procedurefor putting • respirator on, as noil as the i sinmasnnert removal procedure for each respirator type, is listed below.

Putting on the Respirator

• Visually inspect respirator for defects.• Release straps to full open position.• . Holding respirstor in one hand, place respirator to face so that the chin is inserted into chin cup of

respirator.• Push respirator up to face end hold it to face while each strap is pulled to tighten respirstor.• Pull loner straps reasonably tight. Try to pulF both sides of loner straps simultaneously.• Pull top straps until snug.• Straps should hold facepiece securely to face but should not be overly tight.• Adjust facepiece for ceerfort and fit.• Perform negative pressure test by placing hands over the intake valves end inhaling to determine whether air

is leaking in.• Perform positive pressure test by rowing exhalation valve cap (MM respirator only) and placing a hand over

the exhalation valve and exhaling to determine if air is leaking out.• Readjust facepiece, if necessary, until a good fit is tads.

Removal of the Respirstor

• The respirator exterior eey be canteennatod, so care eust be exercised in removing it. A clean pair ofsurgical gloves should be worn while removing the respirator.

• The respirator is one of the last things to be removed when leeving the contaminated erea.• Releese straps and pull respirator over head.• Pull straps over respirator faceshield to protect the lens (full facepiece only).• Lay respirator so that it Mill not become contaminated inside and Hill not contaminate other things.

Follow the cleaning/disinfecting procedure in SECTION 9.0 of this Appendix.If the respirator is not cleaned et this time, it is pieced in the designated 'dirty* plastic beg, kept in thestorege box. to be cleaned at a later time. After it is cleaned, it is placed in the designated 'clean*plastic bee. • —— - -- - - - ••- •-

Alcohol wipes ere included in the respirstor boxes to cleen the inside of the respirator, the sealing flange,end the outside of the respirator (in that order) between uses throughout the day.

Respiretor filters or cartridges should be discarded sfter 8 hours of use or when breathing difficulty orbreakthrough occurs.

RESPIRATOR PROGRAM

7.0 RESPIRATOR FIT TESTS

A qualitative respirator fit test, using irritant aanke to detect leaks in the facepiece-to-face seat is given toassure a good fit. The fit test procedure description follows.

Respirator Fit Tests

• The respirator is put en.• Negative and positive pressure teats are performed.• A 3M Qualitative Fit Test Hood (FT-10) is placed ever the employee's head.• irritant smoke is directed toward the faceseal surfaces, constantly challenging the facapiece to face seal.

Irritant smoke is generated fro* a Ventilation Smoke Tube (NSA Part Ho. 5M5).• Exercises performed by the employee are: head side to aide, head up and down, deep breathing, running in

place, normal breathing, recitation of "Rainbow Passage". Reciting the "Rainbow Passage" out loud causes themouth to move in a variety of contortions and serves as a good tool to test respirator fit. Smoke is directedtoward the stressed faceseal surface.

• If there are no signs of leakage (i.e., throat irritation), the respirator is considered to fit that aaployee.• The employee signs the Respirator Fit-Test Record Fora, and the person conducting the respirator fit-test also

signs the record form, indicating that the aaployee successfully passed the fit-test. The aaployee say beassigned a respirator of the sajat style and site along with a storage box with the appropriate accessories.

8.0 RESPIRATOR MAINTENANCE/REPAIR

Employees should perform emergency respirator repair (e.g., valves, gaskets, etc.) as nssdad while working on sitescovered by the Birr Health and Safety Policy Manual. An Equipment Maintenance Technician is available fornonenergency repairs.

9.0 RESPIRATOR CLEANING/SANITIZING PROCEDURE

•err employees are responsible for cleaning/sanitizing their respirator facapieces after each use. Thecleaning/sanitizing procedure is suaiarized below:

• (reek down the respirator into its component parts.• Discard the expended filters or cartridges.• Discard head straps and valves if they are too contaminated to be cleaned or are no longer functional.

Wash res»ining parts in war*, water with a Mild detergent (USA Cleaner-Sanitizar II or similar). Scrub partswith a soft brush.

• Rinse.• Air dry respirator in a clean area.

• Place respirator in "clean* plastic bag, seal, and place in storage box.

APfEHDOC F: AIR HOBTOM6

1.0 OVERVIEW

Air monitoring is conducted to help verify that the level of protection selected is appropriate for different phasesof the field operations. Heel -tie* air emit or ing using direct reading instruments is conducted based on the natureof site activities. Consideration for reel-tie* air monitor ing should be conducted Nhen:

• site remediation begins,• operations change,• work begins on a different portion of the site,• eny intrusive site activity begins,• contaminants other than those previously identified are being handled, or• when obviously contaminated materials, leaking druss or containers are handled.

•

Air monitoring efforts ere focused on those Barr employees conducting tasks representative of potential maxisu*exposure and on ell employees likely to be exposed to any substance above the OSHA-Permfssible Exposure Limit (PEL)or other published exposure level.

2.0 MONITORING PROCEDURES

Two types of sir monitoring ere conducted, rest-time end personal exposure monitoring. Real-tie* monitoring provides

instsnt readout end is conducted for on- site screening for exposures to airborne levels of hazardous substances todetermine the appropriate level of employee protection. Personal exposure monitoring involves collecting s samplefor subsequent analysis and is conducted to quantify specific airborne concentrations of hazardous substances.

Monitoring is primarily conducted in the breathing zone. Monitoring also may be conducted at the source of potentialcontamination or at the point of intrusive activity. The breathing zone is an arms within a 2-foot radius aroundthe heed. Information obtained from air monitoring is used to assure proper ee lection of engineering controls,person* I protective levels, work zones, work practices, and to assure compliance with OSHA PELS and other publishedexposure levels.

3.0 INITIAL ENTRY

Prior to initisl entry, a site history is obtained to determine potential contaminants that may be encountered endto assist in personal protective equipment end eir monitoring equipment selection. During initial entry, real-tie*instruments msy be used to monitor for those IOLH conditions that could potentially be encountered such as toxic,explosive, combustible and oxygen deficient atmospheres. When the site history indicates that ionizing radiation

PtOTOTTP\PHASPAPP.93A F-1 Edited: may 7, 1«3

AIR MONITORING

is suspected to be present, real-time instrumentation for determining levels of radiation ere used, elong with HObadges to confirm personnel exposure. Additionally, visual observations are made continuously during the initialentry so that actual or potential IDLN conditions or other dangerous conditions can be noted for present and futureuse.

4.0 SITE CHARACTERIZATION

During site characterization, real-time monitoring is conducted where there is a reasonable possibility for exposure.Reel-time monitoring is continued if the possibility of an IOLN or flammable atmosphere condition exists, or if thereis en indication, besed on initiel entry monitoring, that exposures may approach action levels determined in thePHASP. Additionally, personal exposure monitoring ia conducted when there Is no suitable reel-time instrument tomonitor airborne levels of any of the hazardous substances anticipated.

During site characterization, periodic monitoring is conducted when:

• intrusive activities ere conducted,• work begins on a different portion of the eite,• when hazardous substances other than those identified during initial entry are being handled,• e different type of operetion is initiated, or• when work is conducted in arees where hazardous substances are obviously present.

5.0 SITE REMEDIATION

Periodic reel-time and/or personal exposure monitoring is conducted throughout the remedial investigation phase andduring the actual site remediation phase of s hazardous waste operation, when soil, water, waste, or containers whichcontain or ere suspected to contain hazardous substances sre moved or disturbed. The need for periodic real-timemonitoring is listed in SECTION 1.0 of this Appendix. Personal exposure monitoring is conducted for iarr employeeswho are likely to have the highest exposures to hazardous substances. Personal exposure monitoring is also conductedwhen there is no suitable real-time instrument to monitor airborne levels of any of the hazardous substancesanticipated.

The frequency of personal exposure monitoring will be sufficient to characterize employee exposure and to confirmselection of personal protective levels.

If the eir monitoring results indicate airborne hazardous substances above the action levels established in thePHASP, the personal protective level will be upgraded to the indicated level and afr monitoring continued. If theeir monitoring results indicate that levels are below the action levels established in the PHASP, it may bedetermined that subsequent personal exposure monitoring is not required, and that the current personal employee

• Monitoring Frequency:Periodic: when organic vapors/gases suspected to be present.Continuous: (1) instrument registers above background levels. (2) unusual or unidentified newodors are encountered and instrument registers above background, or (3) discolored soils ereencountered.

7.2 Combustible aas indicator mev be required when;

• Confined space entry.• Excevation/trench entry.• Intrusive activity et s landfill, intrusive activity when neture of hazardous substances present at

site is unknown, and any intrusive activity when combustible gas mmy potentially have eccunulated.• Monitoring Frequency:

Periodic: (1) when organic vapor monitor registers sustained readings above backgrocnd levels or(2) unusual or unidentified new odors are encountered and the organic vapor monitor registersabove background levels.

Continuous: (1) intrusive activity when the neture of the hazardous substances present at siteis unknown, (2) intrusive activity when combustible geses may have potentially accumulated, or (3)the potential exists for a combustible emneftisrs to develop.

7.3 Psrticulate Ceeroaol) Trtr*>itorine mev be required when:

• Hazardous substances ere present at the ground surface and mmy become airborne as dust containing orsuspected to contain hazardous substances.An intrusive activity will be conducted where there is e reasonable possibility for skin absorption,skin irritation, or eye irritation from airborne dust containing or suspected to contain hazardoussubstances.

• An intrusive activity will be conducted where there is a reasonable possibility for exposure topaniculate* which mey exceed a workplace exposure standard or IDLN concent ret ions.

• Monitoring Frequency:

Continuous: when large eree(s) of material containing or suspected to contain hazardoussubstances may become airborne.

7.4 Detector tubes mev be required when:

7.5 Action level determination!

A standard action level has been determined to protect against over exposure to organic vapors and airbornedust containing hazardous substances.

7.5.1 Organic Vapors

An action level of 5 ppm total organic vapors for 10 minutes is generally considered adequate tomaintain exposure levels lower than 50 percent of most TLVs, PELs or STELs (including benzene) ofhazardous substances, whether monitoring with the NNU. OVA, or OVN. The specific action level for siteoperations is described in the PHASP.

7.5.2 Combustible Gases

An action level of 10 percent of the Lower Explosive Limit (LED is generally considered to beprotective for exposure to a flammable atmosphere.

7.5.3 Total Dust

An action level of 5 mg/m' total dust (50 percent of nuisance dust TLV} will generally be moreconservative than an action level determined for specific paniculate compounds.

To determine if 5 mg/m* total dust is protective enough for the hazardous substance of concern, followthe procedure provided below:

1. Multiply the known fraction of the hazardous substance in the soil by the action level for totaldust to determine what the airborne concentration of the hazardous substance would be at the dustaction level assuming that all dust generated contains hazardous substances at that concent ration.Compare with 50 percent of the TLV. PEL, or STEL (whichever is lowest). If the airborneconcentration is lower, the action limit should remain 5 mg/«*.

Example;

The PEL for lead is 0.05 mgV. Fifty percent of the PEL is 0.025 mg/m*. If the concentration ofthe lead in the soil is 1,000 mg/kg (or ppa):

Calibrate at altitude in which the instrument will be used.

For Low Ranoe Operation; The instrument contains a catalyticplatinum filament which comprises one -arm of a bridge circuit.When combustible gas in the atmosphere enters the catalyticfilament well and maker contact with the catalyst on the surfaceof ttw filament, a combustible gas-oxygon reaction occurs,increasing ttw temperature of the filament. This increase intemperature causes an increase In filament resistance whichunbalances the bridge. The resultant bridge signal voltage isread out on the meter as the X of the LEL.

For Hi ah Ranee Operation: To measure the concentration ofcombustible gas above the LEL of the mixture, a heated thermalconductivity (TO filament, which comprises one arm of a secondbridge circuit, is used. When combustible gas in ttw atmosphereenters the TC filament wall and passes over ttw filament, itlowers the temperature of the filament. This decrease intemperature causes a decrease in filament resistance whichunbalances the bridge. The resultant bridge signal is read outon the mater as ttw X of gas in the atmosphere.

1.0 POLICY

It is tarr's policy that aaployoas shall not antar any axcavation for the purposas of investigation or constructionobservation without a claarly defined need and without specific authorization. Specific authorization for entryonto an excavation requires an evaluation, prior to each and every entry, by a tarr aaployee designated to be aCompetent Person or an appropriately trained Mrr aaployee to determine if the excavation is safe for entry.

2.0 DEFINITIONS

2.1 Excavation; An excavation is any •en-Bade cut, cavity, trench, or depression that ia foraed in the earth'ssurface by an earth removal or earth Moving process. Any such cut, cavity, trench, or depression that isless than four feet in depth or has side slopes of epproxiwtely 4M.-1V or flatter shall not be consideredan excavation regardless of depth.

2.2 Control of the Site; That entity that has control of the site has the authority to direct the activitiesof the workers that are perforating the earth raanvsl or earth Moving operations. During typical siteinvestigation activities involving one or acre iarr subcontractors, tarr would be in control of the site.During typical construction observation activities involving one or apre of the Owner's contractors, thecontractor or Owner would be in control of the site. However, atypical contractual situations occur that•ay aodify the control of the site for either investigation or construction observation activities.

2.3 Competent Person; Competent Person Beans one who has experience and ia capable of identifying existingand predictable hazards in the surroundings, or working conditions which are unsanitary, hazardous, ordangerous to employees, and has the authority to take prompt corrective •eaauras, or to direct that promptcorrective •sasuras be iapleaanted, to eliminate the unsanitary, hazardous, or dangerous conditions. Whentarr has control of the site, the Competent Person will be s designated tarr aaployee who Beets the abovecriterie and has also received the training set forth in appropriately trained tarr eaployee. When tarrdoes not control the Competent Person will be an designated Owner's aaployee or daaignetad employee ofOwner's contractor.

2.4 Appropriately Trafnad tarr JBOlovee: An appropriately trained tarr aaployee ia that aaployee designatedon project specific basis that has received training that includes

• The requirements of these axcavation entry procedures;

The requirements of the OSHA Excavation Entry Standard (29 CFR 1926.650);

. Properties of soils and method* to classify soils in accordance Mith the requirements of 29 CFR1926.650;

. Construction methods including determination of inclination of side slopes and comaon uses ofshoring, sheeting, trench boxes, benched excevatlone, and excevation machinery; and

• Construction site health and safety end the use of personal protective equipment and clothing.

An appropriately trained Barr employee is not, by definition, e Competent Person as defined previously.

2.5 Side Slopes; Side slopes ere those vertical or inclined eerth surfaces formed es s result of theexcavation work.

2.6 Slopes 1.5H:1V or Flatter; Side slopes thst are sloped at an angle not steeper than one end one-half unitshorizontally to one unit vertically (34 degrees from horizontal).

2.7 Slopes 4H;1V or Flatter; Side elopes that are sloped at an engle not steeper then four units horizon tellyto one unit vertically (U degrees from the horizontel).

3.0 REPORTING OF EXCAVATION ENTRY DEFICIENCIES

3.1 Control of the Site bv Barr; Barr employee* Marking Mith any Barr subcontractor conducting obviouslydeficient excavation entry prectices should Immedietely direct the subcontractor's site eupervisor orforemen to comply Mith the requirements of their contract and correct their excavation entry precticeawithout delay and before proceeding Mith the work. Barr employees and Barr's subcontractor Mill not beauthorized entry into the excavation until the Identified deficiencies are corrected. After directing thesubcontractor, Barr's employees shall alee immediately report all deficient excavation entry practices byBarr's subcontractor to the Project Manegsr or Princtpal-In-Charge. Prior to going into the field eachBarr employee oho 11 obtain from the Project Manager (PN) or Principal-In-Cherge (PIC) a Hat of alternatePN'a and PIC'* to be contacted in the event that neither the Project Manager or Principal-In-Cherge areavelleble. The Barr employee ahall also obtain a list of office and home phone mmtiiri for the PN, PIC.and their eltematee from the Health and Safety staff prior to leaving the office.

The Project Manager, Principal -In-Cherge, or their designated alternates ahall determine wjwther thesubcontractor'* response to the Barr employee'a direction has been adequate to correct the deficient

excavation entry practices, or the subcontractor's work should be suspended until the subcontractor agrees,in writing, to correct the deficient conditions and acts to correct those conditions.

3.2 Control of the tite bv Otfterst Mrr employees, serving as construction observers, should report anyobviously deficient excavation antry practices immediately to the Project Manager, Principal-In-Charge,or their designated alternates. Prior to going into the field each Mrr employee shall obtain fron theProject Manager (PM) or Principal-ln-Cherge (PIC) a list of alternate PM's and PIC's to be contscted inthe event that neither the Project Manager or Principal-ln-Charge are available. The Mrr employee shsllalso obtain a list of office and home phone numbers for the PM, PIC, and their alternate* from the Healthand Mfety staff prior to leaving the office. The Principal-ln-Charge, or the designated alternate, ofterappropriate consultation with the Project Manger, will determine whether to call it to the attention ofthe owner's contractor, the owner, or both the owner and the owner's contractor.

3.3 unauthorized Excevation Entry by ftp- Employees; Any Mrr employee observing another Mrr employeeentering an excavation without the authorization required by these Excavation Entry Procedures shall1} immedistely inform the other Mrr employee that further antry should not occur until authorized and2) immediately notify the Project Manager or Principal-ln-Charge of the circumstances and identity of theemployee involved. Repeated excavation antry, without the required authorization, by a Mrr employee willbe cause for appropriate disciplinary action by Mrr.

4.0 EXCAVATION ENTRY PROCEDURES

No Mrr employee shall consider entry into e excavation unless it has been clearly demonstrated that entry isnecessary to perform e work task. Careful consideration and discussion should be given to developing alternativemethods of accomplishing the work task without having to enter the excavation. Excavation entry should beconsidered to be the method of last choice for the performance of any specific work task. When and only when itis demonstrated that entry into an excavation ia necessary to perform a work task, and either the Project Managerand/or the Principal-ln-Charge. or Mrr's Competent Person en-site, agree that it is necessary to perform thatwork task, will the excavation entry procedures described below be implemented to authorize such excavation antry.

*-1 Control of the tite bv Mrr; The Competent Person may authorize excavation antry, whether by Mrremployees, the employees of Mrr's subcontractors, or anyone elae including the Owner and representativesof any regulatory agency, only when:

It has been demonstrated that excavation entry is necessary to perform a specific work task;

The Competent Person performs an inspection of the excavation;

No iarr employee may be authorized to enter the excavation until theaxcavation entry procedure described in paragraph 4.2 has bean completed by the appropriatelytrained iarr employee on the aite.

6.0 EXCAVATION ENTRY CHECKLIST

In addition to other requirements an Excavation Entry Checklist must be completed prior to excavation entry. TheExcavation Entry Checklist is presented in decision tree form in Figure 6-1. An actual Excavation Entry Checklistwill be of a fora similar to Figure 6-2. To aasist in using the Excavation Entry Checklist when making thedeterainstion of whether to enter an excavation, the various elements of the checklist (and decision tree) aredescribed in the following paragraphs.

6.1 Side Slopes 4H;1V or Flatter; If any cut, cavity, trench, or depression formed in the earth's surface hasside slopes of approximately 4H:1V or flatter it is not an axcavation and the excavation entry checklistdoes not have to be completed before entry.

6.2 less Than 4 Feet Deep; If any cut, cavity, trench, or depression formed in the earth's surface hes a depthof less then 4 feet it is not an excavation and the axcavation antry checklist does not have to becompleted before entry.

6.3 Hazardous Atmosphere; Monitoring for toxic substances, oxygen content, and combustible gases will beconducted if a hazardous atmosphere is suspected.

6.4 Complete CSE Permit: A Confined Space Entry Permit is required for antry. if there is a reasonablepossibility that hazardous substances may be encountered during antry.

6.5 Control of the Site; iarr personnel should obtain this information from tha PM or PIC before going to thesite. Control of the site does not affect only axcavation antry.

6.6 Confer Mitf* CBIBI?*"* Poison; The appropriately trained iarr employee has met with the Competent Personrepresenting the entity that has control of the site and aaid Competent Person has confirmed that in

6.9 Desien bv P.E.; Sloping, shielding, benching, or shoring systems for excavations greater than 20 feet deepshall be designed by s Registered Professional Engineer (P.E.) in that atate in which the excavation islocated.

6.10 Slopes 1.SH:1V or Flatter: The side slopes of the excavation have to ba slopad at an angle that is flattarthan one and one-half horiiontal to one vertical (34 degrees from horizontal).

6.11 Soil Classified t Allowable Slope Documented; Soils may ba classified using the visual and manual soilclassification methods described in the OSHA Excavation Entry Standard to determine the maximum allowableslope. Results of this classification and the allowable slope shall be documented in the Project SafetyDiary or on the Daily Safety Report fora.

6.12 Inspect Sloping. Shielding. Shorina. and/or Benehina; Verify thet sloped portions of the excavation are:

• 1.5H:1V or flattar; or• flatter than the maximum allowable elope; or

>ly with the requirements of the Ragiatarad Professional Engineer's cartifiad daaign.

For those axcavations that include shielding, shoring, and/or banching systaaa. verify that tha ahialding,shoring, and/or banching systaaa ara In good atata of repair and comply with tha relevant drawings(cartifiad by Ragiatarad Professional Engineer for excavations awe than 20 feet daap).

1.0 POLICY

Confined spaces are any excavation, trench, msnhole(s). vessel, or other enclosed apace where there may be a

potential for dengerous eir concentrations (defined In 2.2.1.1 below), limited egress, or engulfment. Barr has

establiahed confinad apace antry procedures that comply with Minnesota OSNA Regulation 5205 • Confined Spaces.

These regulations require Barr to establish training programs and procedures for Issuing permits for employees

who must work in confined spaces.

All Isrr employees ere required to follow the larr Confined Space Entry Program. Entry to confined spec**

generally requires permitting, eir monitoring, and ventilating. The Karr Confinad Space Entry Permit Form must

be completed prior to any confined apace entry and followed during the confinad apace antry.

2.0 DEFINITION OF CONFINED SPACE

2.1 Minnesota Occupational Safety and Health Standard 5205-Confinad Spaces mandates minimus requirements for

confined space entry. The following definitions hove been excerpted from this stendard.

2.1.1 Confinad Space Entry is any action resulting in any part of a person's face breaking the plane of

any opening of the confined apace, and includes any work activities inside the confined apace.

2.2 Confined spaces are defined as a speciel configuration that could reault In any of the following:

2.2.1 Atmospheric Condition - a condition in which a dangerous air contamination, oxygen deficiency, or

oxygen enrichment may exist or develop; where

PtOTOTTP\PNA8PAPP.93A N-1 Edited: Nay 7, 1993

CONFINED SPACE

2.2.1.1 Dangerous Air contamination ia defined aa:

a) an atmosphere containing gas or vapor at a concentration greater than 10 percent of itslower expletive liait (LED,

b) an atmosphere containing particulataa at a concentration greater than 10 percent of theminimum explosive concentration, or

c) an atmosphere containing'a toxic, corroaive, or asphyxiant aubstance in excess of the OSHApenaiaaibla exposure liait (PEL), or abort-tana exposure Unit (STEL);

d) an atmosphere containing a toxic, corrosive, or asphyxiant substance in excess ofiBMdiately Dangerous to Life or Health (IOLH) level.

2.2.1.2 Oxveen Deficiency is dafinad aa an atmosphere containing leas than 19.5 percent oxygen byvolume; and

2.2.1.3 Oxvaen Enrichment is dafinad as an atmosphere containing greater than 23 percent oxygen byvolume;

2.2.2 Entry/Exit Access - s condition where the mmsrgsnry removal of a suddenly disabled person is difficultdue to the location or aize of the access opening; or

2.2.3 Enoulfmmnt Condition - e condition where the risk of enaulfaant exists or could develop.

3.0 ATMOSPHERIC CONDITIONS

Examples of conditions potentially leading to Dangerous Air contamination or Oxygen Deficiency/Enrichmant:

• Organic decay depleting oxygen and generating Methane (combustible and asphyxiant); and hydrogen sulflde(combustible and toxic);

• Rust formation consuming oxygen; or• Other known, suspected, or unidentified chemical reactions specific to the confined apace.

4.0 CONFINED SPACE CLASSIFICATION

There are three classea of confined apace - Claaa IA and Ii, Claaa II, and Claaa III. Each of those types aredescribed below and summarized in TABLE N-1: EXAMPLES OF CONFINED SPACE CLASSIFICATIONS. Theae confined spaces havebaan claaaifiad according to the classification schema described in the Minnesota Confined Spaces standard.

Air is nontoxic and necessary to support life. Inhalation of air in a high pressureenvironment such as underwater diving, caissons or hyperbaric chambers can result insymptoms similar to overexposure to pure oxygen. These Include tingling of fingers andtoes, abnormal sensations, impaired coordination and confusion. Decompressionsickness pains or "bends" are possible following rapid decompression.

TOUCOL06ICAL PROPERTIES

High pressure effects (greater than two atmospheres of oxygen) are on the centralnervous system. Improper decompression results in the accumulation of nitrogen in theblood.

SPECIAL MANDUMC ftCCOMMKMDAnOMi

Valve protection caps must remain in place unless container 1s secured with valveoutlet piped to use point. Do not drag, slide or roll cylinders. Use a suitablehand truck for cylinder movement. Use a pressure reducing regulator when connectingcylinder to lower pressure (C3,000 pslg) piping or systems. Do not heat cylinder byany means to increase the discharge rate of product from the cylinder. Use a checkvalve or trap in the discharge line to prevent hazardous back flow into the cylinder.

For additional handling i I Oas AaaoctoMn P*mpn*t P. v

Protect cylinders from physical damage. Store 1n cool, dry, well-vent Hated areaaway from heavily trafficked areas and emergency exits. Do not allow the temperaturewhere cylinders are stored to exceed 130F (54C). Cylinders should be stored uprightand firmly secured to prevent falling.or being knocked over. Full and empty cylindersshould be segregated. Use a "first In-first out" inventory system to prevent fullcylinders being stored for excessive periods of time.

UVUr UpuMa't •1.

Dry air is noncorrosive and may be used with all materials of construction. Moisturecauses metal oxides which are formed with air to be hydrated so that they increasein volume and lose their protective'role (rust formation). Concentrations of S02»Cl?. salt, etc. 1n the moisture enhances the rusting of metals In air.

Compressed gas cylinders should not be refilled except by qualified producers ofcompressed gases. Shipment of a compressed gas cylinder which has not been filledby the owner or with his (written) consent 1s a violation of Federal Law (49CFR).
