1.0 INTRODUCTION

Conestoga-Rovers & Associates, as the Project Management Consultants (PMC) for the Muggah Creek Remediation Project, has prepared this Environmental Management Plan (EMP) for the Demolition of Above Ground Structures and Removal of Residual Material – Former Coke Oven Site, Sydney, Nova Scotia (Project), to outline measures to be undertaken for the protection and enhancement of the environment.

The EMP is intended to be a dynamic document that will evolve and be updated to meet the changing needs of the Project as it proceeds through each element. The EMP includes environmental protection, air quality monitoring, emergency response and contingency plans.

1.1 BACKGROUND

The Joint Action Group (JAG) recommended that the government parties implement a project to demolish the above ground structures and remove the residual materials presently located at the Coke Ovens Site (Site). The goals of the project are to remove physical hazards, reduce the potential for human contact with the site materials, prevent the spread of contaminated materials away from the site and to stabilize the site prior to further studies and remediation.

1.2 PROJECT ACTIVITIES

Despite previous decommissioning and demolition efforts the Site remains host to several derelict structures, much surface debris, and an unknown array of subsurface infrastructure. The purpose of this project is to demolish all of the remaining aboveground structures and to remove most demolition debris and residual surface materials from the Site. To facilitate the demolition activities, a new access road to the Site will be constructed. Site support infrastructure for future remedial efforts will be established along this new access road. The Project work will include the demolition, removal and disposal of the following structures: ��No. 5 and No. 6 Battery Stacks: two reinforced concrete stacks that are 69 metres and

61 metres tall, respectively; ��No. 6 Coke Oven Battery: the remains of concrete, brick, and steel structures

reduced to mounds of rubble;


��the By-Products Building: a partially demolished structure of approximately 1520 square meters area;

��the Sulphur Building: remnants of a highly deteriorated concrete walled building located at the eastern extremity of the site;

��the Domtar Tank: an open top, 6 metres high, steel tank, 28 metres in diameter, that contains a consolidation of materials from previous decommissioning activities at the Site;

��the Benzol Tank: a large closed top, steel bottom tank of 23 metres diameter and 16 metres height (removal of contents only). Depending upon the condition of the tank and possible future needs, the Benzol Tank may remain on-site; and,

��the Benzol Plant Area Tank: a 3 metre diameter, 12.6 metre long steel tank lying horizontally on the ground.

In addition to demolition and disposal of the above structures, the Project will also include removal and disposal of the following materials:

��a stockpile of approximately 473 tonnes of elemental sulphur located within the

remains of and adjacent to the Sulphur Building; ��Domtar Tank contents: approximately 1355 cubic metres of liquid, 92 cubic metres

of sludge, and 2247 cubic metres of solid material; ��the Benzol Plant Area Tank contents: reported to be equal depths (~ 0.1 metres ) of

sediment, water and oil; ��the Benzol Tank contents: approximately 21 cubic metres of petroleum hydrocarbon

sludge (contaminated with benzene, toluene, xylenes and naphthalene); ��a stockpile of wood Cooling Grid debris; ��a quantity of unprocessed coal from the Coal Storage area, the quantity is estimated

to be between 8,000 to 29,000 tonnes (quantity to be surveyed in Spring 2001) ; ��a stockpile of coke breeze, estimated quantity 9,000 cubic metres (quantity to be

surveyed in Spring 2001); ��miscellaneous surface debris including wood and scrap steel. A new access road will extend from the end of Teak Street to the southeast corner of the Coke Ovens Site. Site support facilities including a vehicle wash pad, wastewater treatment facility, personnel wash house and other site offices will be located at the southeast corner of the Site.

Figure 1.1 provides an aerial view of the site showing the location of the various structures and materials and their proximity to the surrounding community. Figure 1.2 provides general details regarding the new access road and site support facilities.


The Project does not include demolition and/or removal of underground structures remaining on the Site, the removal/remediation of the tar cell, or final site reclamation. The nature of these projects will be evaluated along with the Site’s overall remediation program.

1.3 PURPOSE/OBJECTIVES OF EMP

The EMP provides details regarding measures to be undertaken during the implementation of the Project to ensure the protection and enhancement of the environment and human health.

Specific objectives of the EMP are as follows: ��Define activities which may have an impact; ��Define mitigation and control measures; ��Identify responsibilities; ��Development and implementation of an air monitoring plan; ��Establish decision making processes; ��Emergency response planning including procedures, response actions and

responsibilities; ��Development of contingency plans; ��Verification of accuracy of selected environmental assessment predictions; and ��Assessment of the effectiveness of measures taken to mitigate the adverse effects of

the project.

Each of these objectives is described within the balance of this EMP report. Although careful consideration is always given to the completion schedule and cost, these two items will not necessarily be used to limit the types and frequency of control and contingency measures to be implemented. Imposition of a control or contingency measure will always be followed by a review of the effectiveness and appropriateness of the control measure. For all planned activities, stopping of an activity is an available measure that will be implemented when other control and contingency methods are not effective. Resumption of the activity is always of paramount importance (the project needs to be completed) however, resumption will not occur unless effective control measures have been implemented to the satisfaction of the PMC.


1.4 PROJECT ORGANIZATION

A project organization chart is presented on Figure 1.3.


2.0 PROJECT SCHEDULE

The sequence of project activities as of the date of this document is presented on Figure 2.1. This arrangement of activities is based on all activities having undergone a Canadian Environmental Assessment Act (CEAA) screening. Activities have been scheduled so that the potential impact of overlapping activities does not result in the deterioration of air quality to unacceptable levels in residential areas.


3.0 WEATHER MONITORING AND WEATHER FORECASTING

A weather station has been located at the Site to enable monitoring of precipitation barometric pressure, temperature, wind velocity, and wind direction. The data will be automatically logged and recorded for retrieval as necessary. In addition to monitoring ambient conditions at the Site, the local weather forecast, as broadcast by Environment Canada, will be monitored by the PMC and contractors throughout the day. Changes to planned activities may be made when unfavourable weather is forecast. For example, if high wind speed is forecasted, planned Site activities for a given day will be restricted to those activities that do not generate dust. Additional information regarding this item is provided below in Section 4.1.1. A summary tabulation of the on-site weather conditions will be made daily, and will be included as part of the daily air monitoring report.


4.0 ENVIRONMENTAL CONTROL MEASURES

The projects included in the Above Ground Structures and Removal of Residual Materials at the Coke Ovens Site will be sub-divided into five separate contracts as follows: 1. Infrastructure: Includes the construction of a new access road from the

southeast corner of the fenced portion of the Coke Ovens Site to Teak Street and construction of a Site Support Area which will include:

i) a personal hygiene facility; ii) office trailers; iii) a vehicle wash pad; and iv) wastewater treatment facility.

2. Tank Contents Removal: Includes the removal, transportation and disposal and

treatment (if necessary) of the contents remaining within the Domtar Tank, Benzol Tank and Benzol Area Tank. The Contract will also include the cleaning of the tanks and the dismantling of the Domtar Tank and Benzol Area Tank. The Benzol Tank condition will be evaluated for and considered for use in future projects.

3. Stacks Demolition: Includes the demolition of the Battery Nos. 5 and 6 stacks.

4. By-Products Building Demolition: Includes the demolition of the building and

disposal of the sulphur pile and cooling grids.

5. Bulk Material Removal: Includes the removal and salvage/disposal of the remaining piles of coal, and coke.

6. Above Ground Structures: Includes the demolition of above ground structures including Battery No. 6 foundation, coal conveyor structure and sulphur building. Also includes the removal and disposal of miscellaneous building debris scattered across the Coke Ovens Site.

Controls will be placed on each contractor to ensure that Site activities do not cause unacceptable on or off-Site impact. These controls are in addition to monitoring conducted by the PMC and others during the construction activities. A summary of the mitigation and/or control measures is presented in Table 4.1.


4.1 GENERAL CONTROLS

Controls that will be placed on all work include the following: ��Dust particulate control;

��Erosion and sediment control;

��Weather and wind speed controls;

��Restrictions of working hours from 7:00 a.m. to 7:00 p.m.;

��Air quality controls;

��Development and implementation of Site-specific Health and Safety Plan;

��Implementation of a Environmental Management Plan;

��Implementation of a Contingency and Emergency Response Plan;

��Equipment and personnel decontamination.

The specific requirement of each of the above are outlined in the following paragraphs and in Section 4.2. 4.1.1 DUST AND PARTICULATE CONTROL

All contractors will be contractually required to control the creation of dust.

4.1.1.1 DUST AND PARTICULATE CONTROL – CONTROL MEASURES

Controls will include but not be limited to: ��Restricting vehicle speeds while on Site;

��Wetting traveled areas;

��Wetting removal operations;

��Restricting rate of work activities.

Should perimeter air monitoring for PM10 indicate exceedances of 43 ug/m3 then additional control measure will be implemented by the Contractor to attempt to reduce the value. Should perimeter air monitoring for PM10 exceed 86 ug/m3 then all activities will be stopped until an effective control can be implemented.


4.1.1.2 DUST AND PARTICULATE CONTROL - RESPONSIBILITIES

The contractors will be required to implement dust and particulate control measures. The PMC and others will be responsible for monitoring perimeter dust and particulate levels and directing the contractor to implement any necessary controls to maintain dust and particulate levels below the established criteria. 4.1.1.3 DUST AND PARTICULATE CONTROL - MONITORING

Dust and particulate matter will be monitored at the perimeter of the Site by an independent air monitoring consultant in accordance with the Air Monitoring Plan provided in Appendix A. 4.1.2 EROSION AND SEDIMENTATION CONTROL

Measures to control erosion and sedimentation during the course of the Project will be implemented at the start of each Site activity, and will be maintained until each Site activity is complete. Objectives of erosion and sedimentation control will include the minimization of surface soil erosion and sedimentation of waterways at the Site. 4.1.2.1 EROSION AND SEDIMENTATION CONTROLS – CONTROL

MEASURES

Erosion control measures will include the installation of silt fences along all down gradient sides of work areas and around areas of disturbed adjacent surface such that the drainage channel does not erode the sediments. Erosion and sediment control measures will be consistent with the Nova Scotia Department of the Environment publications entitled “Erosion and Sediment Control: Handbook for Constructions Sites” (1998). Erosion control measures will be inspected daily and after each rainfall. Maintenance of the silt fences, straw bales, stockpile covers etc. will be performed at least monthly, and after heavy rains (rainfall greater than 25 mm in 24 hours) or as required. Long term erosion control measures include the installation of a temporary soil cover on areas of the Site where coal, coke, sulphur and cooling grids are removed. This temporary soil cover will reduce the potential for erosion and migration from the site of remaining coal, coke, sulphur and site contaminants. The temporary soil cover will be seeded and mulched. The growth of vegetation will serve as a wind buffer to reduce wind scouring and to control run-off from rainfall. The Site grades will be adjusted in


the areas of coal, coke, and sulphur removal such that minimal slopes are maintained. This will keep surface scouring and channeling of the soil cover to a minimum. 4.1.2.2 EROSION AND SEDIMENTATION CONTROLS - RESPONSIBILITIES

Installation, monitoring and maintenance of erosion control features will be the responsibilities of the contractors selected for the various aspects of the works. Weekly inspections as described in section 4.1.2.3 below, will also be performed by the PMC to ensure that the objectives of soil erosion control are being met. An evaluation of the control measures will be provided to the Nova Scotia Department of Transportation and Public Works (NSTPW). 4.1.2.3 EROSION AND SEDIMENTATION CONTROLS - MONITORING

Monitoring of erosion control measures will be conducted daily by the contractors, weekly by the PMC and after heavy rain events (rainfall greater than 25 mm in 24 hours). Monitoring will include the visual inspection and evaluation of all erosion control features, with recommendations for replacement or additional measures to be taken. The visual inspection of the erosion control features will be made during a rainfall event so that the effectiveness of surface water control features can be reviewed. Localized discharge points of channeled surface flow will be monitored such that sediment carryover can be evaluated. The upstream and downstream flow of brooks passing through the Site (Coke Oven Brook and Cagney Brook) will be visually compared to determine whether Site activities are causing degradation of these streams during rain events. 4.1.3 WEATHER AND WIND IMPOSED CONTROLS

Although the actual weather cannot be controlled, Site activities can be controlled during periods of unfavourable weather conditions. Unfavourable weather conditions can cause excessive dust to be created at the Site as well as poor dispersion of emissions generated during work activities. 4.1.3.1 WEATHER AND WIND IMPOSED CONTROLS – CONTROL

MEASURES

Weather imposed restrictions will be imposed during work activities as follows: 1. Where running average wind speeds during any previous hour exceeds 35 km/hr

and where there is no trend toward diminishing wind speed as measured during the


previous half hour, the work activity will be suspended until the average one-hour wind speed is below 35 km/hr.

2. Wind gust speeds exceeding 70 km/hr with a trend towards repeated similar gusts

would result in similar temporary suspension of activities until the frequency and speed of gusts decrease. Occasional (one or less per hour) gusts greater than 70 km/hr would not require suspension of activities unless indicated by air monitoring (i.e. frequent exceedances of the air quality criteria).

3. When handling volatile materials, stable wind conditions may result in a need to

shut down operations; the need for this will be assessed based on air monitoring results.

4. Severe weather conditions such as heavy rainfall or thunderstorms may cause work

activities to be temporarily ceased. Work activities will be temporarily suspended should severe weather conditions have the potential to cause harm to the workers, the public, or the environment if work activities were to continue.

Wind speed and direction will be monitored and recorded, with the average and gust speeds being continuously determined and displayed at the weather monitoring station.

An exception to the above controls will be work activities conducted within the temporary enclosure for the Domtar Tank contents removal or indoor, no-intrusive activities such as plumbing, electrical, etc. As this activity will be protected from weather conditions such as wind or rain the controls will not apply to work activities conducted within the enclosures. Air quality controls outside of the enclosure will still be imposed. 4.1.3.2 WEATHER AND WIND IMPOSED CONTROLS - RESPONSIBILITIES

Weather and wind conditions will be monitored by the PMC. The PMC will be responsible for evaluating weather conditions and determining when work activities will be temporarily suspended. 4.1.3.3 WEATHER AND WIND IMPOSED CONTROLS - MONITORING

As discussed previously in Section 3.0, a weather station has been established adjacent to the Site Support Area. The weather station will be capable of monitoring precipitation, wind velocity and direction, ambient temperature and barometric pressure. The data will be automatically logged and recorded for retrieval. In addition,


weather forecasts will be evaluated daily and planned work activities coordinated with contractors as necessary. 4.1.4 RESTRICTION OF WORKING HOURS

All contractors working hours will be restricted to 7:00 a.m. to 7:00 p.m. Exceptions will be the operation and maintenance of the following: 1. Temporary Enclosure and Ventilation System for the Domtar Tank Enclosure;

2. Temporary Wastewater Treatment System.

4.1.5 AIR QUALITY CONTROL

As part of the determination of the interim separation zones as described in the Development of Interim Separation Zones Report (Separation Zones Report), ambient air criteria (AAC) have been established that are considered to be conservatively protective of human health. These AAC were developed specifically for the demolition and removal activities described in Section 1.2 of this EMP. A summary listing of the AAC is presented in Table 2.1 of the Air Monitoring Plan (AMP presented in Appendix A). 4.1.5.1 AIR QUALITY CONTROL - CONTROL MEASURES

The control measures described in the Separation Zones Report are focussed on ambient air quality since AGRA Earth & Environmental Limited (AGRA) identified that migration of substances via air was the most critical route of exposure to the environment and human population. Air quality control will be maintained by general controls described in section 4.1 and by activity specific controls described in Section 4.2. 4.1.5.2 AIR QUALITY - RESPONSIBILITIES

A summary of mitigation control measures, action items and monitoring responsibilities is provided in Table 4.1. The selected contractor(s) responsible for performing the various items of the work will each be responsible for maintaining control of their work, for making adjustments, including implementation of controls and or contingency measures to their work based on monitoring results. An air monitoring consultant will be performing the perimeter monitoring described in the AMP included in Appendix A. Communication at the Site between the PMC, air monitoring personnel and remedial activity personnel will be


maintained to ensure that all Site personnel are aware of the site activities and air monitoring results. As it is most likely that different contractors will be employed at the Site with different responsibilities, the PMC will ensure that all Site contractors contractually have programs in place that allow for communication between personnel of different employers, so that important information regarding monitoring results are communicated to all personnel in a timely manner. The PMC will advise NSTPW of Site activities, air monitoring results and invoked control or contingency measures. Site personnel will be informed of any changes or enhancements that are adapted to the EMP or to the AMP. The communication of these requirements to all Site personnel is of paramount importance to ensure that the EMP and AMP are successfully implemented. 4.1.5.3 AIR QUALITY CONTROL - MONITORING

The procedures to be implemented for real time, and long term (collection of samples for laboratory analyses) air monitoring are described in the AMP. 4.1.5.4 LONG TERM AIR MONITORING PROGRAM

During the implementation of this project a separate long-term air monitoring program will be ongoing. The long-term air monitoring program will be conducted external of this program by the Air Monitoring Consultant. 4.1.6 HEALTH AND SAFETY

4.1.6.1 HEALTH AND SAFETY – CONTROL MEASURES

Work on the Site will be conducted in accordance with the Master Health and Safety Plan. Each selected contractor and/or consultant will be required to submit to the PMC for acceptance a Project-specific Health and Safety Plan (HASP) for its workers. 4.1.6.2 HEALTH AND SAFETY – RESPONSIBILITIES

Each contractor and consultant will be responsible for implementing their Project-specific Health and Safety Plan.


4.1.6.3 HEALTH AND SAFETY – MONITORING

Each contractor and consultant will be responsible for monitoring their respective personnel for health and safety. The PMC will monitor the contractor and consultants implementation of the Project-specific Health and Safety Plan. 4.1.7 CONTINGENCY AND EMERGENCY RESPONSE

Each contractor will be required to prepare and implement a Project-specific Contingency and Emergency Response plan that will be specific to the work activity being performed or met the requirements of the Emergency Response Plan developed by the PMC. The Project-specific Contingency and Emergency Response Plan will be consistent with the Emergency Response Plan prepared for the Muggah Creek Remediation Project and provide more specific details regarding the work the contractors completing. The decision whether a “Site-Specific” Emergency Response Plan is required by certain contractors will be made by the PMC based upon the complexity of the work being conducted by the individual contractor.

4.1.7.1 CONTINGENCY AND EMERGENCY RESPONSE – CONTROL MEASURES

1. The Emergency Response Plans will cover topics such as:

Preventative Measures such as training, site security, waste management, storage of machinery, equipment and materials.

2. Emergency notification procedures including emergency definition, storms, spills, releases, vehicle accidents, personal injury, crime activity, fire emergency, notification and investigation, and documentation.

3. Response procedures including: site evaluation, response procedures in the event of fire, personal injury, spills/releases, and responsibilities

4.1.7.2 CONTINGENCY AND EMERGENCY RESPONSE – RESPONSIBILITIES

As part of the review of the Emergency Response Plan, all personnel and agencies potentially involved in responding to a non-routine event will attend an emergency response coordination meeting, prior to the start of each individual demolition contract, hosted by the PMC. Meeting participants will include representatives from local emergency responders (fire, police, paramedics), CBRM Emergency Measures Coordinator, emergency room coordinator from the local hospital, Coast Guard, Environment Canada, Transport Canada and Nova Scotia Department of the


Environment and Labour, as well as the contractor, the PMC, representatives from NSTPW, and JAG. At this meeting, planned site activities and routine operations will be discussed. Each type of non-routine situation will be reviewed, with duties assigned to appropriate personnel and designated alternates. The Emergency Response Plan will include a listing of the potential non-routine events, along with the assigned duties and responsibilities. All Project team members will have a specific responsibility during a non-routine event. The roles and responsibilities of the organization and agency involved in the emergency response are presented on Table 4.2. 4.1.7.3 NOTIFICATION OF INCIDENTS

Depending on the nature of a non-routine event or of an incident, the PMC will notify interested and responsible parties. Such notification will be in writing, with a copy provided to NSTPW. 4.1.8 EQUIPMENT AND PERSONNEL DECONTAMINATION

Off-Site contamination migration will be controlled primarily through equipment decontamination at the work zone, and of the vehicle wash pad for all vehicles leaving the Site. Wastewaters from the equipment decontamination and vehicle wash pad will be handed as described in Section 4.2.1. Initial equipment cleaning will comprise bulk material removal by scraping with a shovel or other suitable tool. The equipment will then be washed with high pressure, high temperature water amended with detergent or solvent as required. Following washing, the equipment will then be rinsed with clean water. The contractor and the PMC will inspect the equipment prior to equipment being removed from the Site. Re-cleaning will be conducted, as necessary until the equipment is visually clean. Although worker protection will be described in the Site-specific Health and Safety Plan (HASP), procedures for removal and proper containerization of soiled personal protective equipment (PPE) will be followed to prevent contamination migration from the Site via Site workers. All workers in contact with Site contaminants will be required to wear disposable PPE. Once soiled, the outer layer of PPE will be removed and containerized at the exclusion or work zone boundary. Workers will then proceed to the wash house located at the Site support area for showering prior to leaving the Site.


4.2 PROJECT-SPECIFIC CONTROLS

Section 4.2 describes controls to be imposed on specific activities in addition to those described in Section 4.1. 4.2.1 WASTEWATER DISCHARGE AND DISPOSAL

Wastewater generated during the course of project activities at the Site will be handled in several manners depending on the source and nature of the wastewater. Overall objectives of wastewater discharge and disposal are to ensure that wastewater generated at the Site is handled in an environmentally sound manner that is reliable and cost-effective. Different wastewater streams anticipated at the Site include: ��Standing water in Domtar Tank, Benzol Tank and Benzol Area tank; ��Sanitary wastewater from site support facilities; ��Vehicle wash pad wastewater; ��Equipment decontamination wastewater; and ��Potentially waters currently within foundations of structures and/or excess waters

generated from wetting operations (if required). A flow chart illustrating the wastewater streams and treatment process is presented on Figure 4.1 4.2.1.1 WASTEWATER DISCHARGE AND DISPOSAL- CONTROL MEASURES

AND MONITORING

Control measures and objectives for each wastewater stream are described in the following subsections. 4.2.1.2 STANDING WATER IN DOMTAR TANK, BENZOL TANK AND

BENZOL AREA TANK

At present, there is approximately 1,355,000 litres of water above the sludge and solid layers in the Domtar Tank. This water was characterized during the Material Sampling Program – Coke Ovens by Cape Breton Environmental Group (CBEG) in 1997. Tank Contents Removal and Disposal Contractor will remove and treat the water from the Domtar Tank and discharge the treated water to the municipal sanitary sewer. The treatment system will include, at a minimum, the following process steps: ��Dual bag filtration, operated in series for suspended solids removal; and,


��Dual aqueous phase activated carbon units operated in series, for removal of organic compounds and final polishing.

The discharge from this treatment process will be required to meet the criteria presented in Table 4.3. The contractor will be required to initially demonstrate that the treatment system can and has been able to achieve the discharge criteria. Accordingly, the selected Contractor will be required to treat and then containerize a minimum of 40,000 litres of treated wastewater, sample and analyze the treated wastewater, and confirm that the discharge criteria has indeed been met. Once the selected contractor has demonstrated that the discharge criteria has been achieved, the selected contractor will be allowed to directly discharge treated wastewater that has been processed by the prescribed treatment system to the municipal sanitary sewer via a temporary forcemain. Samples of treated wastewater will be collected and analyzed for the discharge criteria daily, with analytical results available from the analytical laboratory, within 48 hours after sample collection. These samples will be collected after the second carbon unit in the treatment series. As well, breakthough after the first (primary) carbon unit a selected “compound of concern” after the first (primary) carbon unit will be monitored daily, utilizing a field kit. The selected “compound of concern” will be determined based on relative abundance in the influent concentration and ease and reliability of the field test for the compound. This compound will be determined at the onset of treatment operations. Once breakthrough of the selected compound has occurred, the contractor will be required to discontinue treatment and then replace the second (secondary) carbon unit with a fresh carbon unit, and replace the primary carbon unit with the secondary carbon unit (i.e. the secondary unit becomes the new primary unit, and the fresh unit becomes the new secondary unit). The spent carbon will be characterized and disposed of in a manner consistent with its characterization. Similarly, should the discharge criteria be found to be exceeded, then the carbon units will also be replaced as described above. The selected contractor will also be given the option to either treat on the Site any waters present within the other tanks (i.e. Benzol Tank and Benzol Area Tank) or transport and dispose of the waters at a permitted off-site facility. Should the selected contractor elect to treat on the Site the water present within the other tanks, then the procedures and limits described above would be required for each tank. Influent water quality will be monitored through a visual opacity test. When influent water becomes very murky removal and treatment will be suspended, and solid/sludge removal activity will commence.


Pressures across each of the bag filter units will be measured and monitored each hour of operation. Should the pressure drop across a bag filter suddenly decrease, the treatment system influent will be turned off, the bag filter will be replaced, and the system will be placed back into operation. Should the pressure drop across a bag filter become too great, then the bag filter will be replaced. All piping in the system will be surficial. Piping will be fabricated from the longest continuous lengths feasible so as to minimize the number of connections. As the work will be conducted in non-freezing conditions, frozen pipes are not considered to be an issue. However, as freezing weather can be encountered in early spring or late fall, the temporary water treatment system will be housed in an enclosure that can be heated, to protect the carbon units from freezing. All piping will be visibly inspected at least twice per shift for leaks, kinks and other deleterious conditions. If any leakage is observed, then the discharge will be suspended until the leaks are repaired. The forcemain will be direct laid on the surface, and will be provided with a steel containment at locations of vehicle traffic. All pipes will be emptied and drained at the end of each working day. The influent piping will be removed to prevent back-siphoning. 4.2.1.3 SANITARY WASTEWATERS

Wastewater generated at the site support area will include both sanitary wastes and wash water from the worker wash house (worker showers). This flow will be piped through piping to a holding tank, in which a submersible sewage grinder pump operating on a level switch control, will transfer the wastewater to the existing municipal sanitary sewer system through a new buried forcemain. No discharge criteria will be applied to this wastewater stream. As an additional control measure a high level alarm within the tank that will be interlocked with the portable water supply. When the tank level becomes higher than normal, the water supply to the wash house and the sanitary facility will be automatically turned off. The pressure on the discharge forcemain will also be monitored weekly. Pressure rise could indicate a blockage and lower than normal pressure could indicate a line break. The discharge point of the sanitary forcemain will be visually inspected weekly to confirm that the sanitary flow is indeed being discharged into the municipal sewer system. 4.2.1.4 VEHICLE WASH WASTEWATER

The concrete vehicle wash pad will be used to wash the exterior of vehicles prior to leaving the site to ensure that no site materials are transferred and deposited off the site


from vehicles. The vehicle wash pad will be of concrete construction, with sumps being an integral cast-in feature. Wash waters will be transferred from each sump into a wash water holding tank. From the wash water holding tank, the wash waters will be treated in a wastewater treatment system. The wastewater treatment system will include: 1. Grit and oil water separation within the sumps; 2. Dual bag filtration, operated in series for suspended solids removal; and, 3. Dual aqueous phase activated carbon units operated in series, for removal of organic

compounds and final polishing. The treatment system will be housed within a heated structure to protect the treatment components. The treatment system will be located on a concrete pad that will be provided with continuous perimeter curbing. The pad will be sloped such that any spills or overflows will be directed to the concrete vehicle wash pad. Adjacent to the wash pad and to the treatment housing will be a wash water storage tank. The tank will be of polyethylene construction with a closed top and will be situated on a concrete pad that has continuous curbing and is sloped such that water will drain to the concrete vehicle wash pad. The concrete of the containment will be coated with an epoxy coating that will protect the concrete. A series of baffles within each sump of the wash pad will provide for oil-water separation and heavy sediment removal. The water will be transferred from the overflow side of the baffles to the wash water storage tank. The storage tank will be equipped with a high water level alarm interlocked with the wash pad sump pumps to prevent the pumps from operating when the storage tank is full. Water from the storage tank will be passed through a series of bag filter units with progressively smaller mesh size, followed by passing the water through dual activated carbon units operating in series. Treated wastewater will than be discharged through a forcemain to the sanitary sewer. The inlet to the treatment system will be a submersible pump suspended from the top of the storage tank. The treatment system will be manually operated in a batch mode whenever sufficient water quantity accumulates. Pressures on each side of the bag filter units will be measured and monitored hourly during operation. Should the pressure drop across a bag filter suddenly decrease, the treatment system influent will be turned off, the bag filter will be replaced, and the system will be placed back into operation. Should the pressure drop across a bag filter become to great, then the bag filter will be replaced. Similarly, pressure drop across the carbon units will be monitored.


This wastewater is anticipated to contain only low levels of contaminants and as such will be subject to the discharge criteria presented in Table 4.4. The criteria are the same as those presented in Table 4.3 however, considering the smaller volume of water and the lower level of contamination, a shorter list of contaminants for routine monitoring is proposed. The first 10,000 litres of treated wastewater will be containerized, sampled and analyzed for the discharge criteria presented in Table 4.4 prior to discharge. Upon confirmation that the treated wastewater meets the discharge criteria, wastewater treated in the prescribed treatment system will then be directly discharged via a pressure sewer to the sanitary sewer. The discharge will then be tested bi-weekly (i.e. every two weeks), for verification that the discharge criteria presented in Table 4.4 is being met. Analytical results will be provided to the PMC within 48 hours from the project analytical laboratory and to NSDEL with an additional 24-hours. Breakthough of a selected compound of concern after the first (primary) carbon bed will be monitored daily, utilizing a field kit. The selected compound of concern will be determined based on relative abundance in the influent concentration and ease and reliability of the field test for the compound. This will be determined at the onset of treatment operations. Once breakthough of the selected compound has occurred, operation of the treatment system will be discontinued and the secondary carbon unit will be replaced with a fresh carbon unit, and the first (primary) carbon unit will be replaced by the second carbon unit (i.e. the secondary unit becomes the new primary unit, and the fresh unit becomes the new secondary unit). The spent carbon will be characterized and disposed of in a manner consistent with its characterization. Similarly, should the discharge criteria be found to be exceeded, then the carbon units will also be replaced with fresh carbon units. Satisfactorily treated effluent will be discharged to the sanitary sewer system through a buried forcemain. The forcemain will be constructed to the municipal standards and will be buried below the frost line. A pressure gauge will be located on the discharge pipe. The pressure gauge will be monitored hourly to confirm that the forcemain is operating under pressure and that no leaks are occurring. The forcemain effluent at the manhole will be monitored for apparent changes in water quality and for flow verification twice per shift when wastewater treatment operations are occurring. 4.2.1.5 TANK CLEANING WASTEWATER

The contractor will give the option to either treat on-site any wastewater generated from the tank cleanings or to transport and dispose of the generated tank cleaning wastewaters at an approved and permitted off-site facility. Should the Contractor elect


to treat the tank cleaning wastewater on the site, then the procedures prescribed for Section 4.2.1.2 above would be required for each tank. Tank cleaning wastewater will be generated after all of the solid materials have been removed from the tank. This wastewater will be transferred to a temporary holding tank. The holding tank will be provided with secondary containment. Wastewater from the holding tank will be processed through the treatment system described in Section 4.2.1.2 above, and will then be transferred to the effluent holding tank. 4.2.1.6 EQUIPMENT DECONTAMINATION WASTEWATER

Removal and disposal of tank contents wastewater generated during cleaning of equipment that has had direct contact with Site contaminants will be containerized and characterized. The equipment will be cleaned at the location where it was being used. The following procedure will be used to containerize decontamination wastewaters. A temporary cleaning station will be set up adjacent to the work area. This station will include a bermed and HDPE lined cleaning pad setup with a sump. The equipment will be power washed utilizing a high-pressure, low flow steam cleaner. Wash waters accumulated in the sump will be transferred into a suitable container using either a vacuum truck or a sump pump. Wastewaters will be characterized using either analytical means, or if associated with a specific activity, will be characterized similar to the waste of that activity. Should the analytical results indicate that the equipment wash water is amenable to on-site treatment and the contractor elect to do so, then the wastewater will be transferred to the vehicle wash water holding tank described in Section 4.2.1.2 above for treatment and disposal. If the wastewaters are not amenable to on-site treatment, then the wastewater will be directly transferred into a permitted wastewater haulage vehicle that will transport the wastewater to a licensed and permitted industrial wastewater treatment facility. The contractor for the Removal and Disposal of Tank Contents will be given the option to either treat on the site any wastewater generated from the equipment decontamination process or to transport and dispose of the decontamination process wastewater off the site at an approved and permitted facility. Should this Contractor elect to treat the equipment decontamination wastewater on the site, then the procedures prescribed for Section 4.2.1.2 above would be required for each tank of equipment decontamination wastewater generated and stored on-site. The contractors for all other projects will be permitted to process equipment decontamination wastewater through the Vehicle Wash Pad Treatment System. The


procedures described in Section 4.2.1.4 will be then be applied for each tank of equipment decontamination wastewater. 4.2.1.7 POTENTIAL WATERS CURRENTLY WITHIN FOUNDATIONS OF

STRUCTURES OR GENERATED FROM WETTING OPERATIONS

During the demolition of the above ground structures water within the foundations may be encountered and in order to effectively demolish the structures it may be necessary to attempt to remove these waters. If deemed necessary, the waters will first be tested to characterize the water. In addition, water will be used through the Project for the control of dust and particulate and excess water may be generated. If treatment is determined to be necessary then the water will be treated through a wastewater treatment system similar to the one discussed in Section 4.2.1.4 and discharged to the sanitary sewer. The discharge will be required to achieve the criteria presented on Table 4.5. The treated wastewater will be tested daily while in operation. 4.2.1.8 WASTEWATER DISCHARGE AND DISPOSAL – RESPONSIBILITIES

Responsibility for the wastewater treatment system operation will rest with the selected contractor performing the work. In addition to routine operation of the systems, these responsibilities will include ensuring system(s) integrity, immediate repair of any leaks, immediate clean up of any spills or leaks, and reporting findings of routine system operational checks and discharge flows. The PMC will collect and have analyzed treatment system influent and effluent samples as described in the above sections. The PMC will prepare operational and analytical summary reports for submission to NSTPW on a monthly basis. 4.2.2 SOLID WASTE DISPOSAL

As part of each activity of the project, solid waste material will require disposal. A flow chart illustrating material disposal is presented in Figure 4.2. Anticipated waste streams include non-hazardous, non-dangerous waste such as wood, bricks and other debris; hazardous waste material; coal; coke; sulphur; and steel. The measures for tracking all waste materials at the Site will be similar. Objectives of the solid waste management program are to ensure that non-hazardous wastes are not needlessly added to the hazardous waste stream, and more importantly, to ensure that hazardous wastes are not inadvertently added to the non-hazardous waste stream.


4.2.2.1 SOLID WASTE DISPOSAL – CONTROL MEASURES

Control measures to prevent the cross-contamination of waste streams will include the identification and delineation of the various waste materials at the Site. Materials that have not been previously characterized will be sampled and analyzed for waste characterization parameters. Non-hazardous wastes will be either loaded directly into waste haul trucks at the location of the waste, or will be transferred to a staging area adjacent to the access roadway. All non-hazardous waste, coal, coke, sulphur and steel will be covered with a sealed tarpaulin. All waste loading and transfer operations will be monitored in accordance with the AMP. Hazardous waste materials will, to the extent possible, be loaded directly into waste haul units. Solid waste haul units will be licensed and permitted for hauling the type of material to be loaded. Furthermore, all hazardous waste loads will be lined with polyethylene sheathing and will be covered with a sealed tarpaulin. All trucks leaving the Site will be cleaned and inspected at the vehicle wash pad. Appropriate shipping papers, including waste manifests, bill of lading and inspection forms will be completed prior to a waste load leaving the Site. Each load of waste will be given a unique identification number for tracking purposes. Each type of waste stream will have a unique numerical prefix that will allow for distinction of the type of waste. Only those trucks that have been pre-authorized will be allowed on the Site. To avoid congestion at the loading areas and at the vehicle wash pad, trucks will be scheduled for arrival at the Site. Trucks that are not ready to be loaded, either due to early arrival at the Site or if loading of previous trucks takes longer than anticipated, will not be allowed to wait on Site, but will be staged at a marshalling area near the Site support area. Prior to recommending approval and acceptance of a contractor’s selected waste disposal facility, the PMC may conduct a facility audit to ensure that the selected facility is not only operating in compliance with their operating permit, but also is appropriate for the disposal of a given type of waste. The facility audit will be documented and provided to NSTPW. 4.2.2.2 SOLID WASTE DISPOSAL – RESPONSIBILITIES

The PMC will be responsible for providing initial waste profiling results. The selected contractor will be responsible for ensuring that all waste materials are handled in a proper manner that is consistent with all applicable regulations. The selected contractor


will be required to provide sufficient liability insurance to protect all parties in the event of a mishap. The PMC will inspect each vehicle prior to the vehicle leaving the Site. The selected contractor will be responsible for providing the correct forms for each waste shipment. 4.2.2.3 SOLID WASTE DISPOSAL - MONITORING

Monitoring of solid waste will include the continuous verification that waste materials are being handled and/or loaded with similar waste materials. Tracking of waste loads will be performed for each waste load: from the setting up of an appointment for loading a truck on Site, to the verification of what is being loaded in a truck, to inspecting the loaded and cleaned truck, to obtaining weigh scale receipts and disposal facility receipts. A monthly summary providing a status report of volumes of waste transported from the Site will be provided to NSTPW. 4.2.3 REMOVAL AND DISPOSAL OF TANK CONTENTS

4.2.3.1 DOMTAR TANK ENCLOSURE

The Domtar Tank will be enclosed during the removal of contents. An induction fan will be used to maintain a negative pressure in the building. Air ventilated by the fan will be passed through a series of two granular activated carbon vessels to ensure removal of at least 90 percent of organic contaminants in the evacuated air through each carbon vessel (i.e. 90 percent in the first followed by 90 percent removal in second). Four building volumes will be ventilated per hour. Air quality in the building may still exceed acceptable work place levels requiring use of respirators or self contained breathing apparatus. Air emitted from the granular activated carbon vessels will be periodically checked with a Photoionization Detector (PID) to ensure that organic concentrations are not more than 10 percent of the concentrations within the building. A continuous logging PID will be installed at both the influent and effluent air streams of the first carbon unit and on the effluent air stream of the second carbon unit. The logging device will record the 15-minute rolling average of the total concentration of VOC in the air streams. The logging device will be equipped with an alarm to notify project personnel when the VOC concentration has exceeded allowable limits. The 15-minute rolling average VOC concentration of the air emitted from the first granular activated carbon unit will not be permitted to exceed the lower concentrations of:


1. 10 percent of the influent concentration to the first carbon unit; or

2. 10 ppm

for 15 continuous minutes, and the 15-minute rolling average VOC concentration of the air emitted from the second granular activated carbon unit will not be permitted to exceed the lower concentration of: 1. 10 percent of the influent concentration to the second carbon unit; or

2. 1 ppm for 15 continuous minutes. 4.2.3.2 CONTROLS SPECIFIC TO REMOVAL AND DISPOSAL OF TANK

5.0 MONITORING DATA REPORTING AND EVALUATION

5.1 RESPONSE LEVELS

Within the AMP are action levels that will be used during routine and enhanced monitoring of Site activities. As described in the AMP, routine air monitoring will be conducted during all Site activities. Enhanced air monitoring will be initiated when a routine work zone action level is exceeded. Enhanced air monitoring will be continued until the conditions have returned to below routine action levels. Should Site conditions be such that enhanced air monitoring indicates the continued non-attainment of AAC due to Site activities, appropriate site activities will be suspended. NSTPW will be notified when changes to the level of air monitoring are required. A follow up notification will be provided after the first round of enhanced monitoring. The notification will include a description of site activities, the real-time air monitoring results, the control measures implemented, along with the timing of the next notification and what information will be available at that time. 5.2 REPORTING

The results of routine and enhanced air monitoring results will be collated and assembled in a report by the consultant responsible for implementing the AMP and will be provided to NSTPW and the PMC daily, for the previous day’s air monitoring. The daily air monitoring report will include a summation of all air monitoring conducted, a summation of the air monitoring results for short term air monitoring, a description of actual daily activities and a copy of the weather station report. Also included will be a description of control and contingency measures that were invoked and an evaluation of their short-term effectiveness, together with what notifications of action level exceedences were given. The report will also include results of the long term monitoring that was conducted. If the turn around time to obtain the long term monitoring results is several days, the reported long term monitoring results will be for activities conducted a few days earlier. An evaluation of the long-term results compared with the short-term results will be included with the long-term results.


6.0 ENSURING COMPLIANCE

The key to ensuring compliance with municipal, provincial and federal regulations is to clearly identify those regulations that will apply and regulations that may apply early in the design process. Identification will ensure that any and all regulatory requirements can be resolved and incorporated into the design of the project such that they are a specific requirement of the contract. All regulators will be consulted to identify potential regulatory issues prior to the final design of the Project. Once issues are identified, enforcement of the regulatory requirements must become a contractual obligation. Failure to perform could be grounds for termination of a contract. A resident engineer retained during the course of the project who will be responsible for quality control and will inspect of regulated work activities and who will report accordingly. 6.1 INSPECTION

A resident engineer will be retained to conduct full time engineering oversight of the Project during its implementation. The role of the resident engineer will be to ensure that the contractors initiate and complete work activities in accordance with contract documents, specifications, drawings, site specific EMP, Project-specific HASP, Project-specific Contingency and Emergency Response Plan, and all municipal, provincial and federal regulations. Through the use of a resident engineer, any changes required to the work methods as a result of regulatory issues can be identified and implemented, in the form of a field order or change order to the contract.

6.2 REPORTING

To provide effective reporting of routine project activities and results, reports will be made periodically of timely and relevant information as each activity progresses.

6.2.1 WEEKLY PROGRESS REPORTING

The PMC will prepare a weekly summary report that will be submitted to the Contract Manager and will summarize progress to date, quality control/quality assurance documentation and documentation which ensures compliance with all regulations (i.e. manifests, permits, approvals, authorizations, etc.)


7.0 PUBLIC PARTICIPATION

Throughout the entire project, public participation in the decision-making process has been encouraged and supported. Opportunities for public participation and input to the project activities have included information sessions, presentations to JAG, and public open houses. JAG has made a commitment to notify residents adjacent to the Site prior to the start of on-site activities. Data generated during Site activities will be available to the public through JAG. Consistent with the open philosophy of JAG, continued public participation in an open forum that will address legitimate questions and concerns will be established and maintained throughout the project activities. This forum will include a review of the activities conducted as well as planned, along with monitoring results.


8.0 REGULATORY AND OTHER APPROVALS

PROVINCIAL

• = Dangerous Goods Transportation Regulations • = Activities Designation Regulations – NSDOE has indicated that work conducted on

the site requires approval by NSDOE under the Activities Designation Regulations. • = Air Quality Regulations – these should be addressed by the AGRA Site Separation

Zone Report and/or by the Air Monitoring Plan. • = Dangerous Goods Management Regulations – Will require authorization for the

temporary storage of dangerous goods at the site. These will include decontamination water, construction-derived waste such as solids from the decontamination process.

• = Asbestos Waste Management Regulations – All asbestos-containing materials will be handled in accordance with this regulation.

• = Emergency Spill Regulations – Covered by the Emergency Response and Preparedness Plan and Site-specific HASP

• = Nova Scotia Occupational Health and Safety Regulations FEDERAL

• = Dangerous Goods Transportation Regulations. All waste material transported from the Site will be managed and handled as required to comply with the Federal Dangerous Goods Transportation Act.

• = Migratory Bird Convention Act (1994) • = Fisheries Act • = Canadian Environmental Protection Act.

MUNICIPAL

• = Noise • = Land-use restrictions • = Building Permits • = Sewer By-Laws


9.0 SUMMARY REPORTS

Following the completion of each Project, the resident engineer will be required to submit to NSTPW an overall summary report which will document the quantity of materials removed and disposed, ultimate disposal type and location, all manifests, bills of lading, approvals, permits, and authorizations. The Summary Report will also document the condition of the site at the completion of the project. The Summary Report will evaluate the effectiveness of the mitigation measures and if required suggest recommended modifications. The Summary Report will also assess the accuracy of the environmental assessment predictions for the Project.

The Summary Report will also consider such issues as:

��Was the selected contract process the right method?

��Adequacy of the design, plans and specifications

��Communication issues

��Health and safety issues

��Review of remediation processes, products and equipment

9.1 EVALUATION OF EFFECTIVENESS OF MITIGATION (CONTROL) MEASURES

Control measures will be monitored for effectiveness and appropriateness. If a control measure is found to be ineffective, then the control measure will be evaluated for future use. It is anticipated that an ineffective control measure would be modified, or other types of control measures will be utilized, based on the cause of the control measure being ineffective. For control measures that are invoked as a part of a response to real-time air monitoring, a real-time determination of their effectiveness can be made, resulting in essentially a real-time evaluation. This type of evaluation is included in the AMP. Other control measures will be evaluated as they are invoked. For example, containment booms and erosion control features can be visually inspected after a rain event to check for continued containment and for erosion protection, with repairs, including upgrading of features, made to each if found to be ineffective. For each planned activity, a checklist


of control measures will be prepared that will include prescribed frequencies for control measure evaluation. A copy of completed checklists will be provided to NSTPW.

9.2 ACCURACY OF ENVIRONMENTAL ASSESSMENT PREDICTIONS

Consistent with the modeling completed for the Separation Zones Report, Site activities have been carefully planned to control the expected impact to the environment. By only monitoring and measuring singular activities, actual outcomes should be consistent with predicted outcomes. The effect that control measures will have on a given activity can be effectively evaluated as part of the AMP.


10.0 MODIFICATIONS TO THE ENVIRONMENTAL MANAGEMENT PLAN

As indicated in the introduction section of this EMP report, the EMP is intended to be a dynamic document that will evolve and be updated to meet the changing needs of the Project as it proceeds through each element. Modifications to the EMP may arise from either a result of Site activities, or from external concerns. For example, should a non-routine event that requires the implementation of contingency measures occur as a result of following routine procedures, then the routine procedures will be evaluated and modified. Such modification will be made to the appropriate part of the EMP, or to the attached AMP, with consultation with NSTPW, Nova Scotia Department of Environment and Labour and Environment Canada. The modifications, once adapted, will also be monitored to ensure continued effectiveness. External influences to the EMP might include changes to legislation that require specific evaluations or modifications to procedures being utilized. Externally driven changes will also be reviewed with NSTPW prior to being implemented. Modifications to procedures will be communicated to all Site personnel, as well as to external personnel involved in emergency response. The revised EMP will be distributed along with instructions to discard the previous version of the EMP.

1.0 INTRODUCTION

This Air Monitoring Program (AMP) and Quality Assurance/Quality Control Plan (QA/QC Plan) included in Attachment A has been developed by Conestoga-Rovers & Associates (CRA) for the surface cleanup activities at the Former Coke Ovens Site (the Site) in Sydney, Nova Scotia. The surface cleanup activities include the following: • Construction of Infrastructure • Removal of the Domtar tank contents, cleaning the tank and demolishing the tank;

• Removing the benzol tank contents and cleaning tank;

• Demolition/disposal of two stacks

• Demolition/disposal of by-products building;

• Removing contents from sulphur building and demolition/disposal of remains of sulphur building;

• Removal and disposal of above grade coal and coke piles;

• Demolition/disposal of remains of coke batteries;

• Demolition/disposal of cooling tower grids;

• Demolition/disposal of benzol plant area tank; and

• General surface clean-up.

This AMP supplements a broader community monitoring program which includes sampling not only at the perimeter of the Site but at the Tar Ponds and urban areas remote from the Site, by including sampling specific to individual activities on the Site. The sampling stations for the broader community program are shown in Figure 1.1 and parameters to be monitored at each station are provided in Table 1.1. The air quality criteria for the AMP are the health-based criteria set forth in the "Development of Interim Separation Zones, Former Coke Ovens Site, Sydney, Nova Scotia" (AGRA Earth & Environmental, November 2000) (Development of Interim Separation Zones Report). These criteria are based on 24-hour average concentrations that are conservatively protective of health. The AMP, once implemented, has been designed such that on-Site activities can be modified should 24-hour average (long-term) and real-time (short-term) monitoring indicate that the ambient air criteria (AAC) established in the Development of Interim Separation Zones Report are approached or exceeded.


The QA/QC Plan has been developed to provide a description of the field and laboratory protocols that will be implemented and the quality control and quality assurance required to provide reliable data. This AMP has been organized as follows: Section 1 - Introduction Section 2 - The Air Monitoring Program - includes both short term and long

term monitoring activities Section 3 - Sampling Program – provides a description of the methods that will

be used for the parameters that are being monitored. Section 4 - Reporting Section 5 - Analytical Protocols – description of field and laboratory

procedures Section 6 - Quality Assurance and Quality Control measures Section 7 - Quality Assurance Report -A description of the Quality Assurance

Report that will be provided at the conclusion of the various air-monitoring activities.

Attachment A - Quality Assurance and Quality Control Plan


2.0 AIR MONITORING PROGRAM

2.1 OVERVIEW

During the surface clean-up activities, the potential exists for the emission of air-borne contaminants to the environment that have the potential to create an impact to the workers on the Site and to residents off the Site if at high enough concentrations. The Development of Interim Separation Zones Report indicated that provided controls were imposed during demolition and removal activities, there would be no adverse impact to the community outside of the Site. Air contaminants will be monitored at the Site perimeter and the health-based criteria established in the Development of Interim Separation Zones Report will be used as the comparative criteria. The health-based criteria that will be used are based on a 24-hour average concentration. Table 2.1 provides the health-based ambient air quality criteria from the Development of Interim Separation Zones Report. The table presents criteria presented in the Development of Interim Separation Zones Report for both less than (LT14) and more than 14 days (MT14) exposures appropriate for areas occupied by the public. The LT14 criteria (benzene and methylene chloride only) are based on exposures of less than 14 days, and the MT14 criteria are based on running 24-hour averages greater than 14 days. The interim separation zones were developed within the Development of Interim Separation Zones Report using the MT14 criteria, which are lower than the LT14 criteria. MT14 criteria were used within the Development of Interim Separation Zones Report since the computer modelling used to predict the interim separation zones could only identify highest concentrations over the 5-year modelling period and could not predict the sequence of these concentrations necessary to determine if the exposures would be more or less than 14 days in a row. Both the MT14 and LT14 criteria are based on published information developed by independent health organizations (e.g. United States Environmental Protection Agency (USEPA), Health Canada, Agency of Toxic Substances and Disease Registry (ATSDR)) and are conservative since they incorporate significant factors of safety. As well occupational limits suitable for workers on the Site are presented in Table 2.1. Occupational limits are established at higher concentration than those for the public since workers are typically exposed for shorter periods of time per day than the public, and since workers are assumed to be healthier than potentially sensitive members of the public. To minimize the risk that exceedances of the AAC are encountered, action levels (referred to as “modified ambient air criteria” (MAAC”)) which are criteria based on 1-hour averages are developed. The MAACs will be used to trigger corrective measures along with additional monitoring and frequencies. MAACs for both the MT14 and LT14


criteria are developed. Action levels have been selected for each monitoring parameter to provide assurance that the concentrations of compounds of potential concern (COPC) are not exceeded beyond the Site boundary. Corrective measures will include modification of Site activities and monitoring parameters as appropriate to reduce the risk of exceedances of the health-based air quality criteria. MAACs are presented in Table 2.1 and the method by which they have been calculated are presented in Section 2.3. A weather station has been located on Site to enable monitoring of precipitation, wind velocity, and direction. Ambient temperature will also be monitored during the course of the project. The following air quality parameters will be monitored to assist in controlling Site activities: • volatile organic compounds (VOCs) (total and/or specific compounds);

• polycyclic aromatic hydrocarbons (PAHs);

• particulate matter less than 10 microns in size (PM-10); and

• selected metals.

The monitoring program presented in this AMP consists of two general types of monitoring, as follows: • Short-term (real-time monitoring) which provides for instantaneous or quick turn

around sampling and analysis • Long-term which provides for sampling and laboratory analysis to confirm and

support the results of the short-term program 2.2 RESPONSIBILITY

Overall responsibility for the program during Site activities will be with the Project Management Consultant (PMC) represented by Conestoga-Rovers & Associates, in its capacity as construction oversight managers. An air monitoring consultant (Consultant) will be retained to perform the perimeter air monitoring described in Sections 2.3 and 2.4 which includes real-time dust and gas chromatography (GC) monitoring and the collection of samples for laboratory analyses. Work zone monitoring will be performed by the construction contractor (Contractor)


retained to implement the Site activities. The Contractor will make use of real-time dust and VOC monitoring equipment. Both will report to the PMC’s on-site personnel who will direct the program described in this AMP. The PMC’s Health and Safety officer will supplement the monitoring of the Consultant and Contractor using real-time dust and VOC monitoring equipment. Responsibility for reporting results to health authorities will be with the PMC. 2.3 SHORT-TERM (REAL-TIME) MONITORING

Direct reading instruments will be used to provide short-term (real-time) measurements of the following air quality parameters: • PM-10 (using a "DustTrak", or equivalent equipment);

• total volatiles [using a photoionization detector (PID)];

• Portable GC calibrated for benzene, toluene, ethylbenzene, xylene, and napthalene; and

• Asbestos.

The PMC’s site manager will select specific short-term air monitoring locations on a daily basis according to an evaluation of the weather conditions, primarily wind direction, and the Site activity. A. Routine PM-10 Monitoring A flowchart presenting the real-time PM-10 monitoring program is presented in Figure 2.1. The program can be summarized as follows: Five-minute rolling average of real-time ambient air concentrations of PM-10 particulate is monitored by the Contractor at the downwind side of the work zone. The parameter will be monitored using a DustTrak aerosol particulate monitor, calibrated using a comparison with the gravimetric method (high vol sampler). This comparison will be done by operating both the gravimetric method and DustTrak beside each other for 8 to 24 hours at the start of the project and once every five gravimetric sampling events. In addition to the work zone monitoring performed by the Contractor, PM-10 measurements will be taken at 100-meter intervals generally upwind and downwind of the work activities at the Site boundary every 1.5 hours by the Consultant. At least three locations upwind and three locations downwind of the activity will be monitored for five minutes each. More


upwind and downwind locations will be selected if the size of the activity is large. The upwind perimeter monitoring will provide a general indication of background levels and the downwind perimeter monitoring will provide a general indication of the effectiveness of the work zone monitoring. Should either the work zone activity, or the perimeter boundary measurement indicate an exceedance of the MAAC for PM-10, then the PMC’s Site manager will be notified and additional monitoring will be conducted by the Contractor and Consultant by immediately and simultaneously taking 1-hour rolling average readings upwind and downwind of the activity. The PMC’s Health and Safety Officer will assist with these efforts if necessary. Corrective actions will be implemented at the end of one hour of sampling when either: (a) the downwind measurement exceeds the MAAC for PM-10, and the upwind

measurement is below the MAAC, or

(b) the downwind measurement exceeds 110 percent of the upwind measurement, and the upwind measurement exceeds the MAAC. The allowance of 10 percent accounts for instrument variability, normal variability between locations in an unimpacted air shed and the large factors of safety inherent in each of the action levels.

The corrective actions are described in Section 2.5. Enhanced monitoring at the perimeter will continue to be performed until the corrective actions successfully demonstrate that the Site perimeter PM-10 concentration is below either the MAAC, or below 110 percent of the upwind concentration, if the upwind concentration is above the MAAC. B. Routine VOC Monitoring Using PID Real time monitoring of VOC concentrations during Site activities will be conducted by the Contractor using a PID along the downwind side of the work zone in accordance with Figure 2.2. Only the Domtar Tank emptying and coal removal operations require this monitoring. Generally speaking, the monitoring location will be about 15 meters from the work activity. This monitoring is in addition to the breathing zone monitoring being performed by the Contractor to verify that appropriate levels of worker protection are being implemented. PID measurements are used as an indicator of total volatiles in the air. Since there are no ambient air criteria for total hydrocarbons and since the action levels for the Site-specific VOCs (benzene, toluene, xylene, ethyl benzene, and naptyhalene) are small and less


than the sensitivity of the PID, the implementation of control measures will be based on a comparison of downwind measurements close to the activity (15 m downwind will be used initially, but may be changed depending on a comparison of the PID with the GC) exceeding upwind measurements. The work zone action level 15 m from the activity will be 0.1 ppm. This level is based on computer modeling which indicates a reduction in concentrations from a source approximately 10 m in size, by a factor of 100 between 15m and 500m distance, which is the closest distance between activities and residences. Should this level be exceeded, then the portable GC monitoring program described below will be implemented. C. VOC Monitoring Using GC A portable GC will be used daily to verify that the established work zone action level is effective in maintaining the Site perimeter ambient air concentration below the AAC for the VOC parameters. This verification will only be conducted daily for the first one to two weeks of removal activities for the Coal Pile Runway and Domtar Tank. This sampling may be extended beyond the first weeks should the sampling indicate that results routinely approach or exceed the MAACs. Additional long-term stations may be required based on the portable GC results. Should the portable GC be retained on the site, as described above, and should the Contractor’s PID monitoring indicate that a work zone action level has been exceeded, then the Consultant’s portable GC will be used to determine the actual concentrations of benzene, toluene, ethylbenze, xylene, and napthalene at the Site perimeter at the most downwind perimeter stations. The upwind concentration will be measured at frequent intervals throughout the day, allowing an immediate comparison to be made to the downwind concentration. A comparison of upwind and downwind concentrations will be made, and corrective actions will be implemented when: (a) either the downwind perimeter concentrations exceeds the MAAC for any

parameter, and the upwind concentration is below the MAAC; or

(b) either one of the downwind perimeter concentrations exceeds 110 percent of the upwind measurement, and the upwind measurement exceeds the MAAC.

The corrective actions are described in Section 2.5. GC monitoring at the perimeter as described above will continue to be performed until the corrective actions successfully demonstrate that the Site perimeter VOC concentration is below either the MAAC, or below 110 percent of the upwind concentration, if the upwind concentration is above the AAC.


GC results will be available to the PMC within 45 minutes of sampling. D. Asbestos Asbestos monitoring will be conducted in the breathing zone of workers to confirm that it does not exceed the NIOSH standard of 0.1 fibres per millilitre. This monitoring will be performed for the first week of the demolition of the stacks to confirm that work practices do not result in an exceedance. The sampling and analysis of asbestos will be done using NIOSH method 7400. The analysis will be performed in the field by a technician certified in the identification of asbestos fibres. Provided that there are no exceedances of the NIOSH level in the work zone, there will be no need to perform additional monitoring since dispersion to public area more than 500 m away will result in a reduction of concentration by more than a factor of 20. E. Short-term Monitoring of Metals and PAHs It is not possible to perform real-time measurement of metals or PAHs. It is also not necessary to perform such monitoring since the Development of Interim Separation Zones Report determined that provided PM-10 requirements were met, there is no possibility that metals or PAHs would approach their AAC. In any case, the permanent monitoring stations at Victoria Road (Station 1) and Fredrick Street (Station 2) will be used to confirm this understanding, since both parameters will be monitored at these locations. F. Development of MAACs Short-term monitoring levels (real-time) cannot be compared against the 24-hour criteria in the Development of Interim Separation Zones Report, since the 24-hour value is a time-weighted average concentration. A short-term (1-hour) criteria is required. The 24-hour average concentration is converted to a 1-hour average by using the following equation: MAAC= AAC x (time(lt)/time(st))^p MAAC = Concentration for short-term averaging period (1-hour) AAC = Concentration for long-term averaging period (24-hours) time(lt) = long-term time in hours (24-hours);


time(st) = short-term time in hours (1-hour); and p = stability constant for E and F meteorological classification (stable (0.167). This equation is taken from the Ontario Ministry of Environment's (MOE’s) document entitled “STB Technical Bulletin No. EES-1, Odour Impacts – An Overview” (Science and Technology Branch, February 1996) and is considered conservative. Thus, for example, the PM-10 24-hour average criteria of 25 µg/m3 is converted to a short-term 1-hour average criteria (MAAC) of 43 µg/m3. Corrective actions, as described in Section 2.6 will be required if short term monitoring results indicate PM-10 greater than 43 µg/m3. Table 2.1 provides the MAACs for each compound as converted from 24-hour to 1-hour average ambient air criteria. G. Work Zone Air Monitoring Table 2.1 also presents Occupational Safety and Health Administration (OSHA) levels. These levels will be used during the short-term monitoring program as levels for which donning respirators or self-contained breathing apparatuses would be necessary. 2.4 LONG-TERM MONITORING

The results of the short-term monitoring discussed in the above section will be confirmed by the long-term monitoring performed by the Consultant discussed below. Decisions regarding activities on the Site will be based on the short-term (real-time) monitoring since it provides immediate results that can be used to temporarily halt and/or modify Site activities. However the long-term data provides information necessary to confirm the short-term results or if necessary modify the interpretation of the short-term results. The community ambient air monitoring program presented in Table 1.1 and Figure 1.1 includes two permanent monitoring stations next to the Site which monitor for PM-10, VOCs, PAHs, and metals every 6 days during site demolition activities and every 12 days during periods of inactivity. These will be used to supplement the Site monitoring described in Section 2.3. Additionally, four permanent locations remote from the Site, as shown on Figure 1.1, are monitored for the parameters in Table 1.1 every 6 days during Site activities and every 12 days during periods of inactivity. The permanent monitoring station locations near to the site are shown on Figure 1.1. This monitoring program will


continue during the remedial work at the Coke Ovens Site and will provide ambient air data to evaluate the effects of Site activities to the surrounding area. The two permanent locations near to the Site are appropriate for monitoring the surface cleanup activities for the following reasons: 1) Frederick St. Monitoring Station (PM-10, VOCs., metals and PAHs):

• located between the Coke Ovens Site and the residents to the north;

• previous monitoring at this station will provide good baseline;

• located close to an on-site area where PM-10 VOCs was modelled to potentially exceed health-based criteria in the Development of Interim Separation Zones Report during remediation of the coal pile; and

• close to possible on-Site PM-10, metals and PAHs emissions for Coal Pile, and Domtar Tank remedial activities.

2) Victoria Rd Monitoring Station (PM-10 (to be added) VOCs, metals and PAHs):

• located between the Coke Ovens Site and the residents to the west;

• previous monitoring at this station will provide good baseline; and

• located in an area close to stacks removal activity ; and

• close to possible on-Site PM-10 VOCs, metals and PAHs emissions for Coal Pile, Coke Pile, Benzol Tank, Domtar Tank, Sulphur Pile, Coke Batteries, and Stacks remedial activities.

A mobile monitoring station will also be used which will be equipped with long-term monitoring units for PM-2.5, PM-10, PAHs, metals and VOC sampling. The mobile monitoring station will be located as shown on Figure 1.1 or at other locations as determined appropriate. The location for this station is flexible and will be located based on wind direction, Site activities and previous sampling results. This mobile station can also be used to provide duplicate sampling for quality assurance/quality control. The mobile station will be established north of the Domtar Tank and north of the Coal Pile Runway when removal of these materials is underway. These locations were selected because VOC emissions for the Domtar tank (benzene) and the Coal Pile Runway (benzene) emissions has the potential to go off the Site, although the modelling in the Development of Interim Separation Zones report showed the concentrations of VOCs would not exceed AAC.


This monitoring north of the Domtar Tank and Coal Pile Runway will be conducted on a daily basis for at least the first week during the Domtar tank contents and coal pile removal. Following the first week, will be monitored once every 6 days. Should any long-term results indicate an exceedance of an AAC, the real-time action levels will be revised. Based on the results on the above described monitoring frequencies and locations may be modified to better address work activities and analytes identified. All long-term samples taken adjacent to the Site during Site activities will analyzed and reported within four days of sampling. Otherwise analyses will only be completed and reported within 14 days. 2.5 CORRECTIVE MEASURES FOR THE WORK

2.5.1 WORKER PROTECTION

Corrective measures for the work will not be necessary if elevated levels are detected in the work area. Workers in this area will be protected in accordance with the Site-specific Health and Safety Plan. Provisions in the health and safety plan will require that workers use personal protective equipment (PPE) if specific monitoring results indicate that this is necessary. 2.5.2 OFF-SITE PROTECTION

Should elevated perimeter short-term monitoring results indicate a potential exceedances of the 24-hour AAC, and it is determined that these exceedances are a result of the activities at the Site, activities at the Site will be immediately evaluated and changes will be made to the work until such time that the measured concentrations are below the 1-hour MAAC. The concentrations of the specific parameters at the off-Site locations will be monitored during this period until the concentrations fall below the MAAC criteria. For parameters with LT14 MAACs (benzene) corrective measures will be imposed when the long-term MAAC is exceeded. However provided that no more than 5 consecutive days of readings are between the MT14 and LT14 MAAC and provided that readings for the previous 14 days did not exceed the MT14 AAC, the readings greater than the LT14


AAC or MAAC would not be regarded as exceedances. This is consistent with and more conservative than the ATSDR definition of allowable acute and intermediate exposure.


3.0 REPORTING

Real-time (DustTrak, PID and GC) results will be reported to the PMC a minimum of every four hours. Any exceedance as described in the AMP will be reported immediately to the PMC. Draft long-term results for sampling next to the Site during Site activities will be provided to the PMC within 24 hours of receipt of the result by the Consultant performing the sampling. All records will indicate the time, date and location of sampling, and weather conditions including wind, temperature, precipitation, and barometric pressure. This information will be available from the on-Site weather station. Where there is an exceedance of a MAAC, the sampler will be required to immediately report the results to the PMC. This will allow for the coordination of additional sampling as described in the previous section. Where there is an exceedance of a MAAC for more than four hours, or of an AAC, the sampler or Consultant, as appropriate, will also immediately notify the PMC, who will report such to the Medical Officer of Health and those persons listed on Table 2.3. The same group will also be notified of any reading that causes site activities to shut down. All long-term sampling results will be documented once per month in a formal report. The Report will present the validated results, weather information, Site activities associated with readings and a discussion of the results with respect to sources.


4. 0 SAMPLING PROGRAM

The groups of parameters selected for analysis are based on the chemicals of potential concern (COPCs) identified in the Development of Interim Separation Zones Report. Ambient air sampling will be conducted for the compounds detailed in Table 3.1. The sampling for the long-term air monitoring will be completed over a 24-hour duration, starting at 12 midnight, so the sampling results can be readily compared against the 24-hour AAC in the Development of Interim Separation Zones Report. The general air sample collection protocols are summarised in Table 3.2 and are discussed further below. These methods may be revised following finalisation of the ambient air monitoring program being completed by AGRA. 4.1 VOCS

VOCs will be collected using a 1.7 litre SUMMA® canister or equivalent. The canisters are pre-evacuated in the laboratory and are typically a stainless steel canister. A 24-hour sample will be collected using a flow regulator. The samples will be collected in accordance with Method TO-14A as published by the United States Environmental Protection Agency (USEPA) in the document entitled "Compendium of Methods TO-14A, Determination of Volatile Organic Compounds (VOCs) in Ambient Air using Specially Prepared Canisters with Subsequent Analysis by Gas Chromatography" (USEPA, January 1999). Portable GC samples will be collected using Tedlar bags. 4.2 PAHS

PAHs will be collected using a Graseby-Anderson PS-1 sampler fitted with a PUF/XAD-2 cartridge and a 4-inch diameter particulate filter. The cartridge and filter will be solvent extracted in the laboratory and individual aliquots will be analysed for PAHs. The samples will be collected in accordance with Method TO-13 as published by the USEPA in the Document entitled "Compendium Method 13 Determination of Benzol (a) Pyrene and Other Polynuclear Aromatic Hydrocarbons (PAHs) in Ambient Air using Gas Chromatographic (GC) and High Performance Liquid Chromatographic (HPLC) Analysis" (May 1988).


4.3 PM-10/METALS

Ambient air will be sampled for PM-10 and metals by means of Hi-Volume (Hi-Vol) sampling. PM-10 is determined by the use of glass-fibre filters and uses a collection mechanism that removes particulate larger than 10 microns and deposits only particulate 10 microns and less on the filter. The method of sample collection for PM-10 is USEPA's "Reference Method for the Determination of Particulate Matter as PM-10 in the Atmosphere" (40 CFR Part 50 Appendix M). 4.4 FIELD PROTOCOLS

Attachment A describes the required field considerations to ensure that data of known quality is produced for the ambient air monitoring program. The detailed sampling procedures are provided in the reference methods referred to above.


5.0 ANALYTICAL PROTOCOLS

The analytical methods to be used for analysis of air samples are listed in Table 4.1. A discussion of the methods is found below. 5.1 AMBIENT AIR SAMPLING- VOCs

Collection of samples will be conducted using Method TO-14A from the USEPA document entitled "Compendium of Methods TO-14A Determination of Volatile Organic Compounds (VOCs) in Ambient Air using Specialized Prepared Canisters with Subsequent Analysis by Gas Chromatography" (USEPA, January 1999). VOCs are separated in the air stream by gas chromatography and measured by mass selective detector or multi-detector techniques. The canisters are pre-cleaned in the laboratory. Targeted detection limits are detailed in Table 4.2 5.2 AMBIENT AIR SAMPLING - PAHS

Samples to be analysed for PAHs will require an Anderson (GMW) PS-1 air sampler to collect particulate fractions on glass fibre filters (4 inch diameter) and vapour phase fractions on polyurethane foam (PUF) and XAD-2 resin. Sample collection will follow techniques as they are outlined in Method TO-131. Extraction procedures include overnight Soxhlet extraction, column chromatographic cleanup and evaporative concentration using either a Kuderna-Danish or a rotary evaporator. The sample extracts are then analysed in accordance with USEPA SW-846 Method 82702. Targeted Detection limits are detailed in Table 4.2. Sample trains for PAHs analysis are pre-cleaned and proofed in the laboratory. Exposed cartridges and filters are wrapped in solvent rinsed aluminium foil and are prevented from excess exposure to heat or light. 5.3 AMBIENT AIR SAMPLING –PM-10/METALS

PM-10 will be analysed using USEPA' Reference Method for the Determination of Particulate Matter as PM-10 in the Atmosphere (40 CFR Part 50 Appendix M). The

1 Method from USEPA Document entitled "Compendium of Methods for the Determination of

Toxic Organic Compounds in Ambient Air". 600/4-84-081 (1984) and supplement (1986). 2 Method from United States Environmental Protection Agency (USEPA). Document entitled "Test

Methods for Evaluating Solid Waste," SW-846, November 1986.


methods consists of desiccating and weighing the glass fibre filters prior to sending the filter to the field in a special manila envelope. The sample is returned to the laboratory and the filter is desiccated and weighed again. The difference in weight is the total amount of PM-10 collected during the sampling period. The analytical method for metals is based on digestion of the PM-10 filter. A small portion of the filter and particulate on the filter are digested in an acidic solution. The solution is then analysed by Inductively Coupled Plasma (ICP).


6.0 QA/QC CORRECTIVE ACTION

Field QA/QC requirements are as outlined in Attachment A. These methods may be revised following finalisation of the ambient air monitoring program being completed by AMEC. The need for corrective action may be identified by system or performance audits or by standard QC procedures. The essential steps in the corrective action system will be: i) checking the predetermined limits for data acceptability beyond which corrective

action is required;

ii) identifying and defining problems;

iii) assigning responsibility for investigating the problem;

iv) investigating and determining the cause of the problem;

v) determination of a corrective action to eliminate the problem (this may include reanalyses or resampling and analyses);

vi) assigning and accepting responsibility for implementing the corrective action;

vii) implementing the corrective action and evaluating the effectiveness;

viii) verifying that the corrective action has eliminated the problem; and

ix) documenting the corrective action taken. For each measurement system, the QA/QC Officer will be responsible for initiating the corrective action or the laboratory supervisor, if appropriate, will be responsible for implementing the corrective action. The corrective action taken will depend upon the QA/QC results that did not meet the necessary criteria, and may include qualifying the data


7.0 QUALITY ASSURANCE REPORT

Reports will be prepared on the performance of the measurement system and data quality following each long-term sampling round. Sample results, which are reported prior to completion of data validation, will be labelled as draft. Validated reports will include: i) assessment of measurement quality indicators, i.e., data accuracy, precision and

completeness;

ii) results of system audits; and

iii) QA problems and recommended solutions. The QA/QC Officer will be responsible within the organizational structure for preparing these reports. The final report for the project will also include a separate QA section which will summarise data quality information contained in the QA/QC reports to management, and details an overall data assessment and validation in accordance with the data quality objectives outlined in this SAP, and in accordance with generally accepted data validation criteria.

3) PM-2.5 - USEPA's Reference Method for the Determination of Fine Particulate Matter as PM-2.5 in the Atmosphere (40 CFR Subchapter C Part 50 Appendix L)

QA/QC requirements for the methods above are also detailed in 40 CFR Part 58 Appendix A – Quality Assurance Requirements for State and Local Air Monitoring Stations (SLAMS) and Appendix B – Quality Assurance Requirements for Prevention of Significant Deterioration. The QA/QC requirements for PAHs sampling and analyses are as specified in USEPA's method entitled "Compendium Method TO-13 Determination of Benzo(a)Pyrene (B(a)P) and Other Polynuclear Aromatic Hydrocarbons (PAHs) in Ambient Air Using Gas Chromatographic (GC) and High Performance Liquid Chromatographic (HPLC) Analysis". The QA/QC requirements for VOC sampling and analyses (24-hour sampling) are as specified in USEPA's method entitled "Compendium Method TO-14A Determination of Volatile Organic Compounds (VOCs) in Ambient Air Using Specially Prepared Canisters with Subsequent Analysis by Gas Chromatography". Since this method is an alternative to Compendium Methods TO-1 and TO-2, the QA/QC requirements of these methods are also appropriate. The QA/QC requirements for VOC sampling and analyses (real-time) using portable gas chromatography (GC) is as specified in Appendix B of the above USEPA method. General requirements from these sources are outlined below. Refer to the above documents for full details of the requirements.


A.1 GENERAL QA/QC

All samplers should be located at least 2 meters from any obstruction. The samplers should also be placed under a shelter to protect the equipment and sampling activity from rain. TSP, PM-10, PM-2.5 and Metals - Careful handling of the filter between the presampling and post sampling weighings will be exercised to avoid errors due to loss of fibres or particles from the filter. Filters will be covered during non-sampling periods. Only the outer edges of the filter will be handled. The filter will be folded in half lengthwise so that only surfaces with collected particulate matter are in contact. Non-Powder nitrile gloves will be used. Continuous flow recorder or elapsed time meter will be used to provide total sampler running time and indication of power interruption. Sampler exhaust will be directed via appropriately sized tubing downwind of sampler. PAHs –Use only clean teflon coated forceps while inserting the filter in the filter holder. Use non-fibre producing cotton or polyester gloves when removing the sorbent cartridge from the sampler and retain original aluminium foil in which the sample was originally wrapped. After filter is removed from the filter holder, fold the filter in half twice with sample side inside and place in glass sample container. Sampler exhaust will be directed via appropriately sized tubing downwind of sampler. VOCs – All canisters are to be pressure tested to 207 kPa +/- 14 kPa over a period of 24 hours. All canisters are to be certified clean (<0.2 ppbv of target VOCs) through humid zero air certification program. When field pressure is checked after the sampling period, a vacuum in the canister should be observed. This will ensure the sample was collected over a 24-hour period and that the regulator functioned satisfactorily. A.2 FIELD BLANKS

Table D.1 provides the number of field blanks required for the AMP. TSP, PM-10, PM-2.5 or Metals – The field blank will consist of a glass filter which will be dried, weighed and placed carefully in a sealed manila envelope. The filter will then be sent to the field with sampling personnel, but the filter will not be exposed. Upon submission of the other filter samples, the field blank will also be submitted to test the


accuracy of the weighing scale. One field blank (for each parameter) will be collected and submitted blind to the laboratory for each sampling episode. PAHs - The field blank will be a PUF/XAD cartridge that is shipped to the field and returned, without drawing air through the sampler. During each sampling episode a field blank will be submitted blind to the laboratory. VOCs – For the 24-hour sampling method, the field blank will be an evacuated canister that is shipped to the field and returned, without drawing air through the sampler. During each sampling episode a field blank will be submitted blind to the laboratory. For the portable GC method, 10% of all injections will be field blanks. The field blank will be nitrogen gas and is the second injection in each sample location. A.3 FIELD DUPLICATES

Table D.1 provides the number of field duplicates required for the AMP. TSP, PM-10, PM-2.5 or Metals - a collocated (or duplicate) sample (each parameter) is required to assess precision for 10 percent of all samples taken from the permanent stations. A mobile monitoring station will be used as the collocated station at one of the existing monitoring stations which is expected to have the highest 24 hour concentration. The collocated sampler will collect the samples in the same manner as and concurrently with the existing (primary) sampler. The samplers will be located within 4 meters of each other, but not closer than 2 meters. PAHs – Duplicate samples will be collected at the same frequency as the TSP, PM-10, PM-2.5 and metals methods, above. VOC – The 24-hour sampling method requires the collection of a parallel sample for each sampling event at different flow rates. If the results between the parallel samples are not within 25 percent, then other parallel samples may also be required. If decreasing concentrations are observed for higher flowrates, lower flowrates should be used. For the portable GC method, 10% of the injections must be duplicates. This will enhance the probability that the analysis of the sample reflects only the composition of that sample and not any previous injection.


A.4 FLOW MEASUREMENTS

TSP, PM-10, PM-2.5 and Metals - The flow rate transfer standard will be certified according the method requirements (40 CFR Part 50 Appendix B, L and M). The certified transfer standard will be used to calibrate the sampler flow indicator. The calibration data will be recorded on a calibration data form. Calibration will be conducted prior to commencement of field activities using an orifice calibration unit. Calibration will be based on at least five separate air flows within the specifed range, which will be used to develop a calibration curve. The calibration curve produced from the five point test will be attached to each Hi-Vol unit for use in the field. The sampler flow rates must be audited for accuracy once each calendar quarter for one quarter of the samplers such that each sampler is audited once per year. A random audit is required for less than four samplers such that one of the samplers is selected each quarter. The flow rate check of each sampler will be at its normal operating flow rate using a flow rate transfer standard which is certified. The flow rate standard used for auditing will not be the same used to calibrate the sampler. PAHs – Calibration of the PS-1 air sampler in the field is performed using a calibrated orifice flow rate transfer standard. The flow rate transfer standard will be certified in the laboratory against a positive displacement rootsmeter. Recertification of the orifice flow rate transfer standards is performed once per year. VOC – To verify correct sample flow for the 24-hour sampling method, a "practice" (evacuated) canister is used. A certified mass flow meter is attached to the regulator which is connected to the sample canister. The canister is opened, and the flow regulator is adjusted to the desired flow and recorded. The "Practice" canister, the flow regulator and the certified mass flow meter are disconnected and the flow regulator is attached to a clean certified canister. For the portable GC flows, flows of 60 and 30 ml/min are adjusted by means of a calibrated rotameter. A.5 SAMPLE LABELLING

A unique numbering system will be used to identify each collected sample. This system will provide a tracking number to allow retrieval and class referencing of sample information. Field personnel will maintain a listing of the sample identification numbers with written descriptions of sample location, type, and date. The sample numbering system to be used is described as follows:


Example: A-1597004-140800-AB-001 Where: A = designates sample type (A = air)

1597004 = project number (last 2 digits is the subcode)

140800 = date of collection (day, month, year)

AB = sampler's initials

001 = sequential number designating sampling location The total volume of air sampled, calculated using the average flow rate and the total sampling time will be noted in the field notebook, the chain-of-custody, and the air sampling data sheet. All sample labels will be firmly affixed to the sample containers they identify. Labels will be written using a ball-point pen never permanent marker as the marker could contaminate VOC and PAHs samples. Table D.2 details the types of shipping containers to be used and the labelling protocols. A.6 FIELD LOG AND RECORD KEEPING

The field logbook will be a bound document with consecutively numbered pages. The entries for each day commence on a new page, which will be dated. Corrections will be made by marking through the error with a single line, so as to remain legible, and initialling this action followed by writing the correction. The following information will be recorded in the field log book for each sample collected: i) site location identification;

ii) unique sample identification number;

iii) date and time interval (in 2400-hour time format) of sample collection;

iv) weather conditions at the time of collection;

v) calibration data;

vi) flow rate of each sampling device;

vii) calculation of total volume sampled using average flowrate and sampling time;

viii) any relevant remarks; and

ix) name of sampler.


Additionally, Figures D.1, D.2 and D.3 are the data sheets which will be filled out for each sample to record the flow rates, sampling conditions, and other site specific data. A.7 CHAIN-OF-CUSTODY FORMS

Chain-of-custody forms will be used to track all samples from the time of sampling to the arrival of the sample at the laboratory. Each sample cooler being shipped to the laboratory will contain a chain-of-custody form. Each sample will be identified on a chain-of-custody form and the total volume sampled (calculated using average flow rate and sampling time) will be indicated in the comments field. As well, temperature and barometric pressure will also be denoted in the comments field. The chain-of-custody form consists of three copies, which are distributed to the sampler (pink), and two copies to the laboratory. The laboratory, upon receiving the samples, will complete the two copies. The laboratory will maintain one copy for its records (white). The remaining copy will be returned to the sampler with the data package (yellow). A.8 FIELD EQUIPMENT CLEANING,

SAMPLE CONTAINERS, AND HANDLING

Cleaning of field sampling equipment will be performed by field staff wearing polyester gloves using a stiff-bristled brush and/or laboratory-supplied analyte-free water. Drying of equipment, if required, should employ new unbleached paper towels. Samplers will handle PAH and VOC samples only while wearing non-fibre producing polyester gloves. PM-10 samples will be handled only with non-powder nitrile gloves. Smoking will not be permitted and sampling will not be conducted during precipitation events including rain, sleet, hail and snow. Samplers will not use perfumes, colognes, or other potential VOC-containing substances during sampling events to avoid contamination of sample media. Sample media will not be stored in vehicle trunks or automobile garages during sampling events. Samples will be transported using shipping media detailed in Table A.2 and will be maintained at a temperature of 4°C or less during transport to the laboratory.


Chain-of-custody forms will be completed and placed in a waterproof envelope and shipped with the samples. Chain-of-custody tape will be placed over the lid at the front and back of each shipping cooler to monitor sample integrity en route to the laboratory. The sample custodian will then check the contents of the cooler with those samples listed on the chain-of-custody form. If damage or discrepancies are noted, they will be recorded in the remarks column provided, dated, and signed. They will be reported to the laboratory supervisor who will inform the laboratory manager and QA officer.


B. LABORATORY QA/QC

B.1 ANALYTICAL METHODS

Analytical methods and associated QA/QC used for the determination of target compounds will be consistent with the analytical methods. Some general requirements are outlined below. Refer to the methods for full details on the laboratory QA/QC requirements. B.2 PROOFING OF SAMPLING MEDIA

The laboratory should clean and proof all sampling media prior to the commencement of the field sampling program. As a minimum, the following should be analysed and confirmed to have less-than-detectable concentrations of the target parameters: i) PUF/XAD Plugs: One plug from each batch cleaned will be extracted and

analysed for PAHs;

i) Glass Fibre Filters: One filter from each batch will be cleaned, extracted and analysed for particulate; and

ii) Canister for VOCs: Each canister must be certified clean.

B.3 SURROGATE STANDARDS

PAHs - Surrogate standards will be added to each sample, blank, and spike just prior to extraction and/or processing as a means of monitoring the effectiveness of the analytical method. The recovery of all surrogates together with the laboratory's associated control limits must be included in the analytical report. B.4 REAGENT BLANK

PAHs – Each time a set of samples is extracted or there is a change in reagents, a reagent solvent blank should be processed as a safeguard against chronic laboratory contamination.


B.5 LABORATORY (PROCESS) BLANKS

PAHs – One PUF/XAD filter from every 20 will be analysed prior to shipment to the field. The laboratory blank is a sample generated by the laboratory designed to monitor the introduction of artifacts into the process. The blank level must be less than 10 ng/cartridge/filter assembly for a single PAHs component. B.6 MATRIX SPIKE

Metals - Audit strips for lead will be used to check the analytical method. Glass fibre filter strips containing a known quantity of lead will be tested in the laboratory consistent with the testing procedure for normal testing procedures. Three audit samples in each of two known concentration ranges will be tested each quarter. Each analytical batch (a minimum frequency of one in 20) will contain a check sample comprised of a subset of the analytes to be determined on media matched to the field investigative sample. The laboratory's associated control limits must be included in the analytical report. PAHs - The laboratory must assess the efficiency of the analytical and sampling methods by means of matrix spiking activities. The matrix spiking study will involve spiking the sampling media with the target analytes (or surrogates) in the lab, extracting and analysing the samples in the laboratory. The matrix spike will be performed once per 20 samples. VOCs – Accuracy is determined by injecting VOC standards from an audit cylinder into a sampler. The contents are analysed for the components contained in the audit canister. Percent relative accuracy is calculated by the difference between the target and measured concentrations. The accuracy must fall within 90 to 110 percent for the canister to be deemed acceptable. If it does not fall within this range, the canister must be cleaned and certified again. Although frequency is not provided in the method, an evacuated canister will be charged with a known concentration of contaminant once every 20 samples. B.7 SOLVENT PROCESS BLANK/METHOD BLANK SAMPLES

PAHs – For each batch of samples (every 20 samples), at least one solvent process blank (no cartridge or filter included) will be analysed. Blank levels should be less than 10 ng/sample.


Metals and VOCs should be addressed - one per every batch of 20 or fewer samples. Metals – For each batch of samples (every 20 samples), at least one method blank (no filter included) will be analysed. Metals should not be detected in the sample. VOCs – For every batch of samples, at least one method blank (humidified zero – grade air or nitrogen) will be analysed. VOCs should not be detected above the detection limits. B.8 LABORATORY REPORTS AND TURNAROUND TIME

In addition to the results for the QC samples detailed above, all laboratory results must include the following: i) date received, extracted, and/or analysed;

ii) method detection limits for each parameter;

iii) all associated quality control limits;

iv) analytical results for all samples in units of both ppbv and µg/m3 (any samples containing levels of target analytes near collection media saturation levels will be clearly identified);

v) case narrative detailing any irregularities associated with samples;

vi) surrogate recoveries;

vii) unique report identifier; and

viii) copy of chain of custody.
