1.0 INTRODUCTION

TerranearPMC, LLC (TPMC) has been contracted by the United States Army Corps of Engineers, Sacramento District (USACE) to conduct an environmental remediation project at the former Almaden Air Force Station (AAFS) in Los Gatos, California. This project provides remediation services to remove and dispose of hazardous materials in the buildings at the site and will be performed under contract W91238-06-D-0007. This work is the first phase of a multi-phase project to dismantle the existing facility and return the site to its original natural state.

This Work Plan (WP) describes the activities required to complete the environmental remediation tasks discussed in the USACE Performance Work Statement (PWS) dated 4 September 2010, Revision 15. The documents intent is to describe the physical setting and historical use of the parcel, summarizes previous investigations, reviews the project scope, performance objectives, designates key TPMC personnel who will participate in the project, and summarizes their responsibilities.


2.0 PROPERTY HISTORY AND DESCRIPTION

The following sections present information regarding the history and physical setting of the former AAFS. The data was primarily derived from the Initial Study/Mitigated Negative Declaration for the Almaden Air Force Station Structure Abatement Project (Ascent Environmental, July 2010)

2.1 HISTORY OF PROPERTY

The former AAFS is located on the summits of Mt. Umunhum and Mount Thayer in the Santa Cruz mountains in unincorporated Santa Clara County, approximately 12 miles south of San Jose, California. The AAFS was established in July 1957 as a U.S. Air Force early warning radar base and became fully operational in March 1958 as part of the North American Aerospace Defense Command (NORAD) to monitor Northern California’s airspace during the Cold War. The AAFS was part of the San Francisco Air Defense Sector and was operated by the 682nd Aircraft and Warning Squadron. The site was officially inactivated in 1980. In 1986 the Midpeninsula Regional Open Space District (MROSD) purchased the AAFS. The property is currently part of the Sierra Azul Open Space Preserve.

2.2 DESCRIPTION OF PROPERTY

The former AAFS consists of a complex of former military buildings and facilities. Lacks of use over the last 30 years, exposure to the elements and vandalism have left the structures in a severely dilapidated condition. Most structures on the site contain asbestos building materials, lead-based paints, asbestos containing paint and PCB-containing light fixture ballasts. In some locations, paint and insulation containing hazardous materials have fallen to the ground from the exteriors of the buildings. Hazardous materials identified in buildings are summarized in Table 1.

The Mount Umunhum portion of the site consists of four distinct areas:

Operations area with underground bunker, prefabricated metal building, concrete monolith (support for former radar dish), and steel observation tower;

Cantonment (support area) with garage, clubs, hobby shops at a higher elevation;

Family housing area at the lowest elevation; and

Sewage treatment area.

The Mount Thayer portion of the site has one area:

3.0 ENVIRONMENTAL SETTING

3.1 SURFACE FEATURES AND TOPOGRAPHY

The former AAFS occupies 43.72 acres on the summits of Mt. Umunhum and Mount Thayer in the Santa Cruz mountains near Los Gatos, California. Both summits are approximately 3,480 feet above sea level. The land surface at the former AAFS has been significantly altered from its natural state by DoD occupation of the area: Buildings, roads, paved areas, and other structures dominate the landscape at the former AAFS. The radar tower (Bldg. 102) is located immediately adjacent to a steep slope which is apparently subject to rockslides.

3.2 GEOLOGY AND SEISMICITY

The former AAFS lies within the Sierra Azul Open Space Preserve. The Preserve is underlain by Franciscan Formation and Coast range Ophiolite basement rocks, consisting of sheared and deformed sandstone, shale and volcanic units. The project site itself is composed of sedimentary and igneous rocks. The entire area is highly active geologically. The local faults- San Andreas, Hayward, Calaveras, Sargent, Shannon, and Monte Vista – are considered to be moderately to highly active. No active faults are in the immediate site vicinity.

3.3 HYDROLOGY

There are no seasonal or perennial waterways on the project site. Storm water runoff from the site is received by Rincon Creek to the north, Guadalupe Creek to the northeast, and Hebert creek to the east. Given its mountaintop location, the site is not subject to flooding.

3.4 METEOROLOGY AND CLIMATE

The site is subject to extreme temperatures and high winds (up to 100 miles per hour), particularly during the winter. Work practices, primarily on building exteriors, will take these potential high winds into account.

3.5 ECOLOGY

A variety of locally common wildlife species occupy the site. Rodent droppings have been observed in many of the site structures. Rough skinned newts have been observed in the swimming pool. Some of the vacant buildings may provide roosting areas for several bat species. Common bats known to inhabit the general area are Yuma myotis, free-tailed bat, California myotis, big brown and little brown bats. Pallid bats, a special-status bat, have been documented in the project vicinity. TPMC will provide a minimum 48-hour notification for bat survey, prior to commencement of remedial activities in a building.

Further, all noise emitting equipment shall comply with Santa Clara County Noise Ordinance, as indicated in the CEQA document. Equipment used during activities at Mount Thayer that exceed noise ordinances shall be outfitted with sound enclosures if they cannot be contained in Building 700.

5.2 EQUIPMENT STAGING AND MUSTER LOCATION

The staging of equipment, waste containers, and lay down areas will be located at various locations throughout the Site at the different work areas as shown on Figures 1 through 5. Following remediation and abatement, building 211 will be utilized to store expendable supplies, materials, and small equipment/tools. Additional equipment such as bobcats, forklifts and man lifts will be stored in the main equipment staging area shown in Figure 2. Temporary equipment and waste staging areas will be set up outside of each building as necessary. All lay down and storage areas will be located and setup to minimize the likelihood of disturbance by heavy winds or storms.

Building 211 will also act as the project field office once remediation of this building is complete. All visitors will need to check in to this office to announce their presence and be given a briefing on the Site activities. Portable restrooms will be located here and at additional locations as needed to accommodate active work areas. A minimum of one portable restroom per every ten workers will be provided, with a minimum of one designated female restroom.

The emergency muster location will be located in the large parking lot that acts as the main equipment staging area located near Building 207 as shown on Figure 2. All emergencies will be mustered to this location to await further instruction based on the emergency perceived. Emergencies will be indicated by the repeating three short blasts from an air horn.

Revisions to the staging and muster points based on the work to be performed may be made in the field. The staging locations shall be determined by the FM and muster location shall be discussed daily at tailgate meetings and documented in field logs. If


the SSHO determines that the muster location should be revised, due to the proximity of the activities, existing site conditions, etc, the SSHO shall notify all staff of the change during the tailgate meeting, and briefings to site visitors.

5.3 SITE ACCESS AND SECURITY

Mt. Umunhum and Mt. Thayer are accessed by private roads only. Activities at the Site will be accessed exclusively via Mt. Umunhum Road, a private road with a partial easement by MROSD. TPMC shall comply with waste transport requirements, as noted in the CEQA document. All traffic shall adhere to the requirements of the owners (inclusive of MROSD). All personnel shall adhere to the precautions due to road conditions and be informed of road conditions prior to reaching the site.

Site entry and egress shall be subject to the traffic/security regulations as follows:

All workers shall ensure all locks on the daisy chain locks are locked for each of the five gates on the road to the Site prior to leaving the gate;

All personnel shall be made aware of and abide with applicable posted speed limits; Parking allowed in designated areas only; and Any traffic accidents shall be reported immediately.

Mount Umunhum and Mount Thayer have been subject to vandalism and trespassing in the past. On a daily basis, all on-site structures will be returned to original secured state prior to daily site departure. No site perimeter fencing will be removed during the performance of the scope of work. If the scope changes, or the perimeter fencing is damaged, it will be immediately reported and repaired following the incident reporting procedures outlined in APP

5.3.1 Mount Umunhum Road Access

Activities involving road access via Mt. Umunhum Road shall abide by the following access requirements, at a minimum:

All gates into and out of the site shall be maintained in their closed and secure condition.

No gate will be left open unless the gate is manned. All gates required to access the work areas of the Site will be supplied with a project

specific combination lock. In addition, a limited number of keys (2-3) to existing “Planning Department” locks

will be provided to select project personnel. TPMC shall not lock out any other road user. If TPMC locks out other road users,

TPMC shall be accountable for costs related to replacement of locks. Mt. Umunhum Road runs through the project site, and is the only access for

properties located northwest of the site. Therefore, Mount Umunhum Road, even when on the project site, shall not, at any time, be blocked by project activities.

Mount Umunhum Road is steep, narrow and winding. Winter conditions (rain, ice, snow) can increase these hazards. TPMC shall inform personnel of hazards and reinforce safe driving practices reminding all workers regularly to use heightened caution when driving along the road, to maintain low, safe speeds.


There are numerous residents and business entities that must have open and safe access along Mount Umunhum Road. TPMC shall not at any time obstruct access along any portion of the road. If a lane is blocked, flagmen shall be in place to safely route traffic around obstruction.

5.3.2 Mount Thayer Road Access

Mount Thayer is accessed via a private road. Third party affiliates do not have easements to this road, therefore pre-approved access is required. The PM shall provide 70 hour advanced notification request to the USACE Contracting Officer’s Representative for all road access to Mount Thayer.

5.3.3 Emergency Response Access

All Site logistics plans and operations will take into account the need for emergency response access both on site and along Mount Umunhum Road, and the road to Mt. Thayer. Access will be available on all roads and will not be fully obstructed, except for very limited activities, wherein flagmen will be present to direct traffic. At no time shall all lanes of any road be completely obstructed.

5.3.4 Work Access- Area near Buildings 512 &513

A minimal gravel road with filter fabric may be installed to provide access to the area around Buildings 512 and 513 (Figure 3). The extent of the road will be determined once field work starts to determine the best approach to gain all required access to the work areas. Prior to installation, the area extent and location will be discussed with applicable parties. The gravel road can remain in place following project completion, as per MROSD approval, to allow access for the demolition phase of the project performed under a different project and fire protection access. Alternatively, at project completion, the road can be removed and vegetation restored following project completion.

5.4 ONSITE STRUCTURES

The scope of this project includes the remediation of lead hazards, abatement of asbestos, and the removal of universal wastes in 39 on-site structures, identified in the Performance Work Statement (PWS). Building-specific asbestos removal activities are tabulated in Table 1. It is assumed that all buildings identified in Table 1 contain Lead Based Pain (LBP) and will be remediated as per the PWS. Any buildings requiring remediation, not listed in PWS Table 1, shall adhere to costing and estimating per PWS Task 44 - Reimbursable Structures. The negotiated cost shall be approved by the USACE prior to commencing work. Remediation methods are detailed in Section 6. The SSHO will be responsible for identifying structure-specific hazards (uneven flooring, unsafe entry ways, unprotected holes in flooring, etc.) prior to commencing remediation activities.


5.5 UTILITIES

5.5.1 Power and Water Supply

Limited power and water supply are available at the site. Pacific Gas and Electric (PG&E) supplies power to Building 207. Metered power shall be used where available; all other work areas will use generators.

Water will be hauled to the site via truck and stored in temporary holding containers at the work areas. The frequency and methodology of water distribution will be determined at a later date when the team has mobilized to the Site.

5.5.2 Existing Abandoned Power Lines

If downed power lines are still present once mobilization begins, a utility locator will confirm and mark all potentially live downed power lines prior to the start of work near these lines. Should an unmarked power line be encountered during remediation activities, the line will be treated as live until a qualified entity can confirm the line is not energized.

5.6 MITIGATION PLANS FOR ADVERSE CONDITIONS

High winds, precipitation (snow, rain, and hail), extreme temperatures, fires and earthquakes may be encountered during the remediation services outlined in this Work Plan. This section discusses mitigation measures that will be followed to overcome these obstacles that may be present at the Site.

5.6.1 High Winds

Internet monitoring will be implemented for weather forecasting, and a portable wind monitoring device, will be used to monitor current wind conditions. Exterior remediation activities will be planned in accordance with daily weather forecasts and current conditions. Exterior remediation activities will stop if the site experiences wind gusts exceeding 40 mph or sustained winds exceeding 20 mph for five minutes, or any other unsatisfactory conditions prohibiting progress. All exterior remediation operations will be suspended at any time when satisfactory control of the overall operation cannot be maintained on account of rain, wind, or other unsatisfactory weather or ground conditions. The following additional precautions will be implemented:

Dumpsters, trash containers, will be kept covered and placed in areas protected from prevailing winds;

Whenever possible, when exterior abatement or remediation activities are to be performed, the use of mini-containments will be employed to allow for quick clean-up if conditions change rapidly; and

All scaffolding, if used, will be secured to the structure. Specifically, scaffolding erected for work at the Radar Tower (102) shall be engineered by the third party scaffolding installation company. Due to the seasonal fluctuation of winds, the development of the scaffolding and containment for Building 102 shall be


provided in an addendum to this work plan, two weeks prior to the commencement of activities at the Radar Tower exterior.

5.6.2 Precipitation

As above, exterior remediation activities will be planned in accordance with weather forecasts. Remediation activities will be limited to interior locations when significant precipitation is expected, and will be stopped if unexpected precipitation is encountered that makes the remediation activities difficult.

5.6.3 Extreme Temperatures

Mitigation methods for extreme temperatures are not expected, but procedures are outlined in SSHP.

5.6.4 Fires

The site is surrounded by open space lands that have the potential to be a wildfire hazard. Fire extinguishers shall be visible and accessible at all times in all work areas. When performing activities requiring fire watch, separate safety personnel will be on hand with fire extinguishers or other fire suppressant device. No activities will be performed that pose a fire threat without a proper hot work permit being completed and reviewed. In addition, the following safe work practices will be employed:

Trucks or equipment will not be parked in areas where tall grass is present. Personnel will cut any brush to ground level where necessary to gain access to the

structures and prevent fire dangers. Smoking will be limited to designated areas only. Smoking areas will be properly

marked and designated in an area that is brush free, and will provide for proper fire-safe disposal of smoking products.

In case of a fire, the fire department will be notified via 911. If the fire is small and controllable; fire extinguishers and water will be deployed and the fire department will still be called. In case of any fire, all personnel will mobilize to the established muster location.

Prior to the start of field activities, the Field Manager will schedule an on-site meeting with proper fire control agencies (including CAL FIRE) to confirm that remediation activities are in compliance with local fire prevention and emergency response requirements.

5.6.5 Earthquakes

In the event of an earthquake during remediation operations, personnel shall exit the regulated areas and buildings immediately. All personnel shall follow all instructions as per the pre-project safety meeting and muster at the identified muster point in Figure 2.

5.7 MITIGATION PLANS FOR BIOLOGICAL RESOURCES

MROSD will make separate arrangements to identify specific structures where bats are likely to be encountered (or have already been encountered). USACE will provide this


list to the PM within 2 weeks of mobilizing to the site. A one week notification will be given prior to starting a building which has been included on the list in order the get the bats removed. For all other buildings not likely to house bats, the buildings will be surveyed to look for signs of bat presence at least three days prior to remediation. If bats are encountered where not expected, all mitigation measures discussed in the Mitigated Negative Declaration (Ascent Environmental, July 2010) will be followed. Specifically, notifications will be made immediately, and no work will occur in that building until the bats are removed.

Impacts to nesting birds will be mitigated by limiting pruning of trees and shrubs to the non-breeding/nesting season (October through February).

5.8 MANPOWER REQUIREMENTS

The number of personnel required at the site will vary based on level of activities on a weekly and/or daily basis. A typical crew assigned to each building will vary between 2-5 personnel, but could be larger, depending on the size of the building and the intensity of activities in each building. TPMC shall comply with the manpower limitations described in Acent Environmental Initial Study/Mitigated Negative Declaration for the Almaden Air Force Station Structure Abatement Program dated 26 July 2010 (CEQA document).

5.9 REGULATORY COORDINATION AND COMPLIANCE

In accordance with National Emissions Standards for Hazardous Air Pollutants (NESHAP), written notification will be provided to the Bay Area Air Quality Management District (BAAQMD) ten working days prior to commencement of regulated asbestos-containing material (RACM) activity.

CAL-OSHA notifications will be sent by facsimile 24 hours prior to commencement of lead remediation and asbestos abatement activities.

High efficiency particulate air (HEPA) filtered equipment will be dioctyl phthalate (DOP) tested on-site prior to commencement of activities.


6.0 REMEDIATION METHODS

The methods of remediation of ACM, LBP and Universal Wastes are outlined below. The methods described below and in Table 1 represent the standards of operation based on the predominant conditions presented in the plans and specifications. In minor cases these conditions/, methods will vary. In all cases, the implementation of this project will conform to all applicable laws and regulations.

6.1 ASBESTOS CONTAINING MATERIAL (ACM) ABATEMENT METHODS

All asbestos and asbestos-containing materials, (including asbestos containing materials with content less than one percent), shall be handled as RACM, unless stated or proved otherwise. Class II materials will be removed substantially intact to maintain Class II handling requirements. All asbestos removal will be accomplished in accordance with applicable rules and regulations. Disposal shall be segregated where applicable, as discussed in Section 6.6.

6.1.1 Preparation

The asbestos abatement preparation shall follow the specifications outlined in Attachment 5 of the PWS including the following general guidelines:

All buildings undergoing interior abatement will have critical barriers on the exterior windows and doorways and HEPA filtration will be installed in order to maintain a minimum pressure of -0.02 inches of water at all times.

For exterior abatement activities where full containment is not applicable, additional

means will be implemented such as mini containments will be used, including mini-containments installed on platforms and scaffoldings to work at heights.

6.1.2 General Asbestos Abatement Techniques

The section below describes the general removal techniques that will be utilized on this project. Specific procedures that will be followed for each building and each material are presented on Table 1.

6.1.2.1 Manual Removal

Exterior asbestos containing debris on the ground or loose on/in buildings will be manually removed using wet methods by hand, shovel, or scraper and placed in properly labeled bags and containers. Bags will be goose necked, duct taped closed and loaded into a lined, roll-top dumpster. Larger debris shall be handled by direct load to the lined, roll-top dumpster. The dumpster will be connected to and as part of the containment when debris is directly loaded.

In many cases, the removal of the asbestos containing material that is attached to a structure such as the silver painted metal roofing/siding, mastic on a pipe, and tape at drywall seams, will be accomplished by removing and disposing the component in


whole pieces, rather than just removing the ACM from the component. This will largely be accomplished through the use of manual wet means by removing screws and other tie down material with hand tools and hand-held power tools, and direct loading to a pre-lined roll-top dumpster. Small debris will be placed into proper disposal bags. Large non-friable debris like intact metal roof panels/components will be placed into pre-lined disposal bins and burrito-wrapped. If power tools are used to remove asbestos material, they will have HEPA attachments.

Generally, roof mastics will be removed from substrates wet using hand scrapers and non-powered cutting tools. The debris will be placed into proper clear plastic disposal bags.

Asbestos containing stucco will be removed by manual wet means within containment by scraping, hammering and chipping the asbestos containing plaster/stucco from the structure.

If it appears that stucco, or any other material can be proved to be less than one-percent asbestos, a third party consultant may be hired to perform a 400 point count analysis of the material to prove that it contains less than one-percent asbestos. If this turns out to be the case, this will allow the material to be removed as non-hazardous asbestos containing material. The material will be removed using wet mechanical and hand methods without containment. This will be completed once the interior abatement is complete. Removal will be accomplished with employees wearing proper PPE. Two 6-mil drop sheets will be placed on the ground extending 20-feet away from the building to capture all waste. The resulting waste will be disposed of in 20-yard non-hazardous dumpsters.

If point counting does not conclusively prove that the stucco contains less than one-percent asbestos, then the stucco will be handled as hazardous and will be abated as discussed in this WP as RACM in full containment and disposed accordingly.

6.1.2.2 Wrap and Chop

Thermal systems insulation (TSI) piping will be removed by utilizing the wrap & chop method. This method includes wrapping the entire piping system in plastic, then using glove bags to remove small sections of the TSI to allow the pipe to be cut into manageable sections without disturbing the ACM. Hand tools or handheld power tools will be used to cut the piping. Once the wrapped pipes are cut and lowered to the ground, each pipe section will be properly labeled and placed into a pre-lined dumpster for disposal

6.1.2.3 Self-contained Water Blasting Method

The self-contained water blasting method is one of the methods that may be utilized to remove asbestos containing paint from interior or exterior walls of concrete buildings. This work would be performed under containment or mini-containment. This method uses a truck mounted self-contained pressurized water and vacuum system, piped from the truck to a nozzle attachment. The water levels and pressure are monitored by personnel at the truck, while the nozzle attachment is maintained by separate personnel. The nozzle attachment is pressed directly to the surface of the wall and


wheels on the unit allow it to be rolled along the wall surface. The vacuum inside the nozzle attachment captures the waste water and solids released from the wall. These are accumulated in a separate sealed tank on the truck. The sludge is separated, removed and stored in 55 gallons drums. The water will be filtered and reused. No water used in the abatement process will be allowed to enter the ground. Any residual water will be collected on plastic sheeting and placed in holding containers. Wastes generated in this manner when used on lead and asbestos paint will be profiled for both wastes.

6.1.2.4 Abrasive Wet Blast Method

Abrasive wet blasting is another method that may be utilized to remove ACM containing paint from interior or exterior walls. This method uses an abrasive media with water to scrub wall surfaces. Containment will be built around the abatement area whenever abrasive wet blasting is performed. Standard wet media-blasting equipment is comprised of an air compressor a media pod, and a pressurized water system.

Removal of residual blast media from wall shall be HEPA vacuumed, scraped or washed with airless sprayers and maintained in containment. No water used in the abatement process will be allowed to enter the ground surface. Any residual water will be collected on plastic sheeting. Abrasive media will be collected in plastic bags and placed in properly labeled drums. The abrasive media will be disposed of as ACM waste and also profiled for lead content.

6.1.2.5 Pressure Washing

Pressure Washing may be utilized to assist with final cleaning following complete removal. Pressure washing will always be conducted within full containment. No water used in the abatement process will be allowed to enter the ground surface. Any residual water will be collected on plastic sheeting and filtered/disposed properly.

Following all regulated interior asbestos removal has passed final inspection; the areas will be encapsulated with a lockdown encapsulant such as Fiberset PM, or Foster.

6.2 LEAD BASED PAINT (LBP) REMEDIATION METHODS

6.2.1 Preparation

Barriers and signage will be installed prior to any LBP remediation activities to clearly identify work areas. All LBP activities will be performed using lead safe practices. All lead work areas that occur on the exterior of the buildings will utilize wet methods, HEPA vacuums, scrapers, over plastic drop sheets. All interior remediation activities shall occur within the more stringently controlled asbestos containments with the same engineering controls.

6.2.2 General Lead Based Paint Remediation Methods

Loose and peeling paint will be abated by hand scraping or wet blasting. Once the loose or peeling paint has been removed, the surface will be coated with a lock-down


product to help stabilize the surface and prevent near term future peeling to allow for demolition later with minimal to no additional stabilization

6.2.2.1 Manual Scraping Loose & Peeling LBP

Traditional paint scrapers or razor blade scrapers will be used remove loose or peeling paint. Existing paint chip debris lying on the ground will be collected using manual methods (yard/garden rake, small shovels) and HEPA vacuums. All paint chip debris will be placed into 55-gallon disposal drums and appropriately disposed of.

6.2.2.2 Vacuum Remediation

A final clean will be performed in all areas using a HEPA vacuum. The HEPA filters and vacuumed materials will be properly profiled for disposal.

6.2.2.3 Wet Blasting Peeling LBP

Wet blasting may be chosen to remove the loose coatings inside contained work areas, only. Paint chips will be collected on plastic sheeting, then placed in 55-gallon disposal drums and disposed of as appropriate. Water generated from wet blasting will be captured and filtered and reused or disposed as appropriate.

6.2.2.4 Paint lock-down coating- stabilization

A lock-down coating will be applied to surfaces with remaining stabilized lead based paint. The lock-down coating will be sprayed on using an airless sprayer, roller, or hand pump sprayers. Application of the lock-down layer will only be applied after the applicable QC personnel have inspected the stabilized area.

6.3 DECONTAMINATION PROGRAM

Personnel and equipment decontamination stations will be set up to mitigate the potential for hazardous materials being transported outside of the containment areas. For all Class I and Class II operations where materials are not removed substantially intact, a three-stage decontamination area will be set up attached to each respective building where the activities are occurring.

Lead remediation decontamination requires a wash station for workers to clean and wash their faces. However, as asbestos abatement will be carried out concurrently with the lead remediation, most of the lead areas will have one of the asbestos decontamination setups described below. At a minimum, a wash station will be set up in the vicinity of the lead remediation areas.

6.3.1 Three-Stage Decontamination Area

A three stage decontamination area will be set up for all Class I abatement activities. The three-stage decontamination area will be attached directly to the buildings.

A temporary negative pressure decontamination unit that is adjacent and attached in a leak-tight manner to the regulated area will be provided. The decontamination unit shall


have an equipment room and a clean room, separated by a shower, which complies with 29 CFR 1910.141, unless it can be demonstrated that such facilities are not feasible. Equipment and surfaces of containers filled with ACM will be cleaned prior to removing them from the equipment room or area. At least one shower will be provided for every ten workers (or portion thereof) conducting work in any given containment.

All wastewater shall be collected and filtered to remove asbestos and lead materials. Filters and residue shall be profiled prior to disposal. The filters and residue will be disposed of as asbestos and/or lead contaminated material. Filtered water shall be collected into holding totes and reused as wetting agents, but never applied to the site natural ground surface. Any remaining recycled water will be profiled and disposed of offsite. Wastewater filters shall be installed in series with the first stage pore size of 20 microns and the second stage pore size of 0.5 microns. The floor of the decontamination unit's clean room shall be kept dry and clean at all times. Proper housekeeping and hygiene requirements shall be maintained. Soap and towels shall be provided for showering, washing and drying. Any cloth towels provided shall be disposed of as ACM waste or shall be laundered in accordance with 29 CFR 1926.1101.

6.3.2 Two-Stage Decontamination Area

A two-stage decontamination area will be set up for Class II abatement work, keeping material intact, if a three-stage decontamination area is not already set up for the building. The two-stage decontamination area will consist of two connected plastic cubes. The first cube operates as a dirty room where workers remove their outer layers and use a HEPA vacuum to remove residual debris. The second cube operates as the clean room where workers change into clean clothes.

6.3.3 Single Stage Decontamination Area

A single stage decontamination area will be set up for small projects that do not involve Class I abatement, such as the removal techniques used for the abatement of silver painted metal roofing and mastic as described above.

A single stage decontamination area (equipment room/area) shall be provided for Class III work involving less than three linear or square feet of TSI/surfacing ACM, and for Class II and Class III asbestos work below thresholds where exposures exceed the PELs or where there is a negative exposure assessment. The equipment room or area shall be adjacent to the regulated area for the decontamination of employees, material, and their equipment which could be contaminated with asbestos. The area shall be covered by an impermeable drop cloth on the floor or horizontal working surface. The area must be of sufficient size to accommodate cleaning of equipment and removing personal protective equipment without spreading contamination beyond the area.

6.3.4 Decontamination Area Exit Procedures

The decontamination area exit procedures are as follows:

1. Before leaving the regulated area, remove all gross contamination and debris from work clothing using a HEPA vacuum.


2. Employees shall remove their protective clothing in the equipment room and deposit the clothing in labeled impermeable bags or containers for disposal and/or laundering.

3. Employees shall not remove their respirators until showering.

4. Employees shall shower prior to entering the clean room. If a shower has not been located between the equipment room and the clean room or the work is performed outdoors, ensure that employees engaged in Class I asbestos jobs: a) Remove asbestos contamination from their work suits in the equipment room or decontamination area using a HEPA vacuum before proceeding to a shower that is not adjacent to the work area; or b) Remove their contaminated work suits in the equipment room, and proceed to a shower that is not adjacent to the work area.

6.4 PROJECT COMPLETION/QUALITY CONTROL PLAN

All remediation activities shall be confirmed as complete on a building by building basis by the field manager, and verified by the PM or his designee. All remediation activities will be deemed complete once all asbestos materials and loose and flakey paint has been visually confirmed as removed.

All final clearance and confirmation inspections, if required are provided by the independent third party designee under contract with MROSD.

6.5 HEALTH AND SAFETY

Health and safety requirements are addressed in the APP and SSHP submitted under separate cover for this project.

6.6 WASTE MANAGEMENT

All waste removed from the site will be documented and maintained by the FM. TPMC shall adhere to the maximum allowable number of eight trucks per week, off-hauling waste for disposal as per CEQA documents.

6.6.1 Asbestos Containing Waste

During removal activities, all ACM shall be handled in accordance with OSHA. These materials will be collected in pre-lined, roll-top bins, or drums. The containers will be properly labeled, including the appropriate DOT and OSHA placards. Disposal of asbestos waste will follow EPA guidelines and segregated per EPA standards as RACM and non-friable (CAT I, CAT II) asbestos. UNI Waste Inc. will be contracted to transport and dispose of the ACM.

6.6.2 Lead Containing Waste

All lead waste resulting from scraping LBP shall be off hauled in 55-gallon drums or lined waste bins and disposed of as hazardous materials. After the lead waste profile results are available Allied will determine the transporter of the waste, pending


quantities. Large loads (bins) will be handled by UNI Waste Inc. Smaller loads (drums) will be handled by Future Environmental Services.

Waste that contains both asbestos and lead will be handled separately.

6.6.3 Universal Waste and General Waste

Future Environmental Services will be contracted to transport the universal waste to the disposal facility. Universal wastes, such as PCB containing ballasts, non PCB containing ballasts, mercury-containing waste such as fluorescent light tubes and thermostats, and batteries will be collected in metal drums or in cardboard boxes per requirements. Future Environmental Services will be contracted to transport universal wastes to the disposal and recycling facilities. General waste and construction debris will be collected in roll-off bins and disposed by UNI Waste Inc.

6.6.4 Wastewater

Wastewater accumulated from remediation activities and decontamination activities shall be filtered through a five micron filtration system and recycled for continued remediation activities. Water resulting from activities that disturb both lead and asbestos materials will be filtered through a 0.5 micron filter also. Excess wastewater, not absorbed by wetted material, shall be hauled off site for proper disposal.

6.6.5 Waste Manifests

Copies of waste manifests issued prior to departure from the site shall be maintained in a file onsite. Final waste manifests shall be produced by waste collection facility and returned to the signing generator. All waste manifests will be signed by a direct employee of MROSD or their designated representative. Copies of all waste manifests shall be submitted to MROSD, along with copies of the land ban certification notice, at the construction meetings. All manifests used since the prior construction meeting shall be submitted to MROSD and/or third party monitor at each construction meetings, if not before.
