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 followingstructures:
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;

14458 (24) 2 CONESTOGA-ROVERS & ASSOCIATES
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 thesoutheast 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.

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.

14458 (24) 8 CONESTOGA-ROVERS & ASSOCIATES
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.
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 14/104
14458 (24) 9 CONESTOGA-ROVERS & ASSOCIATES
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 – CONTROLMEASURES
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 onareas 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 15/104
14458 (24) 10 CONESTOGA-ROVERS & ASSOCIATES
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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 16/104
14458 (24) 11 CONESTOGA-ROVERS & ASSOCIATES
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 suspendedshould 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,
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 17/104
14458 (24) 12 CONESTOGA-ROVERS & ASSOCIATES
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), ambientair 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 18/104
14458 (24) 13 CONESTOGA-ROVERS & ASSOCIATES
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.
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 19/104
14458 (24) 14 CONESTOGA-ROVERS & ASSOCIATES
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 willbe 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 – CONTROLMEASURES
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
7/27/2019 CRA-19

14458 (24) 15 CONESTOGA-ROVERS & ASSOCIATES
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 beingremoved 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 ANDBENZOL 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. TankContents 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,
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 22/104
14458 (24) 17 CONESTOGA-ROVERS & ASSOCIATES
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 treatmentsystem 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 thefresh 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.
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 23/104
14458 (24) 18 CONESTOGA-ROVERS & ASSOCIATES
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 ofvehicle 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 beingdischarged 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 24/104
14458 (24) 19 CONESTOGA-ROVERS & ASSOCIATES
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 hourlyduring 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.

http://slidepdf.com/reader/full/cra-19 25/104
14458 (24) 20 CONESTOGA-ROVERS & ASSOCIATES
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 bedetermined 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 26/104
14458 (24) 21 CONESTOGA-ROVERS & ASSOCIATES
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. Atemporary 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 theprocedures 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 27/104
14458 (24) 22 CONESTOGA-ROVERS & ASSOCIATES
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 OFSTRUCTURES 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 toNSTPW 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.
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 28/104
14458 (24) 23 CONESTOGA-ROVERS & ASSOCIATES
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 sealedtarpaulin. 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 29/104
14458 (24) 24 CONESTOGA-ROVERS & ASSOCIATES
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). Fourbuilding 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:

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 notificationand 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 ofactual 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 ContractManager 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.

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

http://slidepdf.com/reader/full/cra-19 38/104
14458 (24) 33 CONESTOGA-ROVERS & ASSOCIATES
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 areasremote 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.

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 InterimSeparation 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 thesequence 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 59/104
14458 (24) Appendix A 6 CONESTOGA-ROVERS & ASSOCIATES
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 itscapacity 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)
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 60/104
14458 (24) Appendix A 7 CONESTOGA-ROVERS & ASSOCIATES
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 boththe 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 61/104
14458 (24) Appendix A 8 CONESTOGA-ROVERS & ASSOCIATES
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 theMAAC.
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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 62/104
14458 (24) Appendix A 9 CONESTOGA-ROVERS & ASSOCIATES
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 totwo 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.

http://slidepdf.com/reader/full/cra-19 63/104
14458 (24) Appendix A 10 CONESTOGA-ROVERS & ASSOCIATES
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 than500 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);
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 64/104
14458 (24) Appendix A 11 CONESTOGA-ROVERS & ASSOCIATES
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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 65/104
14458 (24) Appendix A 12 CONESTOGA-ROVERS & ASSOCIATES
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.
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 66/104
14458 (24) Appendix A 13 CONESTOGA-ROVERS & ASSOCIATES
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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 67/104
14458 (24) Appendix A 14 CONESTOGA-ROVERS & ASSOCIATES
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.
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 68/104
14458 (24) Appendix A 15 CONESTOGA-ROVERS & ASSOCIATES
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).

14458 (24) Appendix A 17 CONESTOGA-ROVERS & ASSOCIATES
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.

14458 (24) Appendix A 18 CONESTOGA-ROVERS & ASSOCIATES
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. TargetedDetection 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

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 includereanalyses 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.

QUALITY CONTROL/QUALITY ASSURANCE
A. FIELD QA/QC
The QA/QC requirements for TSP, PM-10, PM-2.5 and metals sampling and analyses
are as specified below:
1) PM-10 - USEPA's Reference Method for the Determination of Particulate Matter as
PM-10 in the Atmosphere (40 CFR Subchapter C Part 50 Appendix M).
2) TSP and Metals – USEPA's Reference Method for the Determination of Particulate
Matter in the Atmosphere (High-Volume Method) (40 CFR Subchapter C Part 50
Appendix B).
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.

http://slidepdf.com/reader/full/cra-19 88/104
14458(24) Appendix A (Att.A) A-2 CONESTOGA-ROVERS & ASSOCIATES
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 Met al s - 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 powerinterruption. 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 M et al s – 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
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 89/104
14458(24) Appendix A (Att.A) A-3 CONESTOGA-ROVERS & ASSOCIATES
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 M et al s - 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.
VO C –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 willenhance the probability that the analysis of the sample reflects only the composition of
that sample and not any previous injection.

14458(24) Appendix A (Att.A) A-4 CONESTOGA-ROVERS & ASSOCIATES
A.4 FLOW MEASUREMENTS
TSP, PM -10, PM -2.5 and Met al s - 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 willnot 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:
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 91/104
14458(24) Appendix A (Att.A) A-5 CONESTOGA-ROVERS & ASSOCIATES
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 couldcontaminate 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.

14458(24) Appendix A (Att.A) A-6 CONESTOGA-ROVERS & ASSOCIATES
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 polyestergloves 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 reagentsolvent blank should be processed as a safeguard against chronic laboratory
contamination.

14458(24) Appendix A (Att.A) A-9 CONESTOGA-ROVERS & ASSOCIATES
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
M etal s - 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 samplecomprised 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.
7/27/2019 CRA-19
http://slidepdf.com/reader/full/cra-19 96/104
14458(24) Appendix A (Att.A) A-10 CONESTOGA-ROVERS & ASSOCIATES
Metals and VOCs should be addressed - one per every batch of 20 or fewer samples.
Meta ls – 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.
