3. TECHNICAL DEFINITIONS

"Ambient sound level"

means Background sound level;

"Background sound level"

is the sound level that is present in the environment, produced by noise sources other than the source under impact assessment. Highly intrusive short duration noise caused by sources such as an aircraft fly-over or a train pass-by is excluded from the determination of the background sound level;

"Construction Equipment"

means any equipment or device designed and intended for use in construction, or material handling including but not limited to, air compressors, pile drivers, pneumatic or hydraulic tools, bulldozers, tractors, excavators, trenchers, cranes, derricks, loaders, scrapers, pavers, generators, off-highway haulers or trucks, ditches, compactors and rollers, pumps, concrete mixers, graders, or other material handling equipment;

"Conveyance"

includes a vehicle and any other device employed to transport a person or persons or goods from place to place but does not include any such device or vehicle if operated only within the premises of a person;

"Point of Reception"

means any point on the premises of a person where sound or vibration originating from other than those premises is received. For the purpose of noise impact assessment of a proposed landfill operation, or an expansion to an existing landfill operation, the point of reception may be located within 30 m of a dwelling or a camping area on any of the following existing or zoned for future use premises: permanent or seasonal residences, hotel/motels, nursing/retirement homes, rental residence, hospitals, camp grounds, and noise sensitive buildings such as schools and places of worship.

Other technical terms used in this publication are defined in Reference [1] .

4. MEASUREMENTS, STANDARDS AND PROCEDURES

For the purpose of this Publication, all measurements shall be made in accordance with References [2], [3] and [4].



s. SOUND LEVEL LIMITS

(1) Landfill Site

(a) General Limits

The limits for sound levels due to the landfill site operation at a Point of Reception are 45dBA in any hour of the night, 7:00 PM - 7:00 AM, and 55 dBA in any hour of the day, 7:00 AM - 7:00 PM. These levels are expressed in terms of the One Hour Equivalent Sound Level (Leq).

The above limits are applicable under the following conditions:

~ the existing ambient noise climate is assumed to be rural, i.e. the daytime and nighttime environmental noise level is normally below the stated limitation. Should the environment be dominated by noise sources of man-made activity, such as industry, commerce or road transportation, which produce sound in excess of the above limits, the higher sound levels may be used as the limit, provided that the noise sources are not under consideration for noise abatement by the Municipality or the Ministry of the Environment.

~ landfill site operation involves only "construction equipment" or "conveyances", as defined in Section 3. In this case, the landfill site itself is not considered a stationary noise source, and will not be governed by the limitations set out in References [5] or [7] .

(b) Specific Limit - Impulsive Sounds

For impulsive sound from a pest control device employed in the operation of the landfill site, the sound level limit at a Point of Reception expressed in terms of the Logarithmic Mean Impulse Sound Level (LLM) is 70 dBAI.

(2) Facilities for Reception, Storage and Mixing

A landfill site utilizing equipment that does not fall under the definition of "construction equipment" or "conveyance", as defined in Section 3 is considered a stationary noise source. The applicable sound level limits are those established for the assessment of stationary sources of sound given in References [5] and [7].

6. OFF-SITE SOURCE VEHICLES

For a landfill site employing off-site source vehicles which constitute a predominant component of the background noise, an access rout shall be selected which will result in a minimum noise impact. The selection process shall be based on a detailed quantitative assessment of noise impact on individual receptors and the number of affected receptors along the alternative routes. The municipality and the affected residents must be clearly informed of any potential noise impact.



SCHEDULE "C"

This Schedule "C" forms part of Provisional Certificate of Approval No. A 420009. It describes groundwater monitoring program referred to in Condition 39.

1. OBJECTIVES

The objectives for the groundwater monitoring program are:

• to monitor groundwater quality in the overburden and bedrock aquifers;

• to identify and characterize movement of leachate-related contaminants in the overburden and bedrock aquifers within and at the site boundary;

• to evaluate the efficiency of the cut-off wall and the leachate collection system; and

• to determine the need for contingency implementation.

2 • MONITORING PLAN

The groundwater monitoring plan shall be carried out by the Corporation to address the stated objectives and will include the following:

2.1 Monitoring Locations

• Existing Monitors:

The existing groundwater monitors to be sampled are shown on Fig. C.1 of Item 4, Schedule "A" and listed in Table C.1.

• Additional Monitoring Wells:

To supplement the data collected from the existing groundwater monitoring wells, additional facilities will need to be constructed. Specifically, additional monitoring wells are proposed around the inside and outside perimeter of the cutoff wall.

® Ontario

Ministry Ministere PROVISIONAL CERTIFICATE OF APPROVAL of the de FOR A WASTE DISPOSAL SITE Environment !'Environnement NO. A 420009

Page 19of42

Additional monitoring wells BH23, BH24, BH25, BH26 and BH27 will be installed in the Surficial Sand Unit between the perimeter cut-off wall and the landfilling area. These additional installations will allow evaluation of the cut-off wall performance in the immediate proximity of the landfilling area. The water table elevations around the landfilling area must be kept lower than those in the Shallow Aquifer outside the cut-off wall, and also lower than the hydraulic head in the Lower Aquifer to ensure groundwater inflow into the Landfill.

Proposed wells BH23 through BH27 will be installed after construction of the cut-off wall and prior to placement of any waste.

Additional monitoring wells BH17, BH18, BH19, BH20, BH21 and BH22 will need to be installed outside of the perimeter cutoff wall and screened in the Surficial Sand Unit, the Silt and Clay Unit and the Lower Aquifer. These wells will be used for both monitoring the direction of groundwater flow beneath the Landfill and for identifying any potential leachate impacts to the groundwater. These installations should be placed close to the perimeter cut-off wall so that any impacts to the groundwater beyond the wall can be detected as soon as possible. Early detection is critical to the implementation of effective mitigation strategies to prevent groundwater impacts from exceeding RUP criteria at the property boundary . . Porposed wells BHl 7, BH18, BH19. BH20 and BH21 will be installed prior to commencing the landfilling operations.

The proposed monitoring wells are summarized in Table C.1 and their locations are shown on Fig. C .1 of Item 4, Schedule "A".

3. TRIGGERS AND CONTINGENCIES

There are two potential pathways for contaminants to migrate from the Landfill in the groundwater. These pathways are as follows:

• Pathway 1 - Horizontal movement of contaminated groundwater through the Surficial Sand Unit (Shallow Aquifer), Silt & Sand Unit and the top of the Silt & Clay Unit where fractures or more permeable zones exist. Once in the surficial deposits, contaminants may impact surface waters and will move according to the localized flow system. Water level maps indicate that the direction of contaminant migration will be northeast in all hydrolithological units.

• Pathway 2 - Vertical movement of contaminated groundwater through the Silt & Clay Unit to the Lower Aquifer. Should contaminants reach this aquifer, then contaminant movement within the Lower Aquifer is expected to be laterally to the northeast and east of the landfilling area.

There are four possible failure scenarios leading to unacceptable groundwater impacts:

• premature failure of the leachate collection system (LCS);

• failure of the perimeter cut-off wall;

• failure of both the LCS and the perimeter cut-off wall; and

• different movement of contaminants than predicted with the current understanding of the hydrogeological regime.

The first three failure scenarios are applicable to Pathway 1 in which the movement of contaminated groundwater is horizontal and there are potential impacts on the Shallow Aquifer and surface water. The first and last failure scenarios are applicable to Pathway 2 in which the movement of contaminated groundwater is vertical (downwards) and there are potential impacts on the Lower Aquifer. For each of the failure scenarios associated with the two contaminant pathways, contingency measures have been identified.

The implementation of contingency measures is based on the monitoring of the performance of the engineered systems and~,the natural conditions, including:

• groundwater quality outside the cut-off wall and below the Landfill;



• groundwater levels on either side of the cut-off wall;

• leachate quality (to identify whether the Landfill of contaminants measured in groundwater);

is the source

• leachate levels in the LCS and in the waste; and

• leachate quantities removed from the LCS.

Potential failure scenarios, proposed contingency measures, trigger criteria, and the nature of investigations initiated by the trigger criteria are discussed below for the two contaminant pathways.

3.1 Pathway 1 Contingency

~ Premature Failure of the Leachate Collection System (LCS)

The LCS has a design service life of 30 years. When the LCS can no longer control leachate elevations within the waste and leachate mounding cannot be prevented, a perimeter drain system will be installed. The perimeter drain will be installed below the water table elevation in the Surficial Sand Unit so that the groundwater flow direction remains inwards, towards the Landfill.

If the LCS fails prematurely, leachate mounding will occur. If leachate mounding is not arrested, it may lead to a reversal groundwater flow direction. The flow direction may become outwards, away from the Landfill. The discharge of leachate to ground surface could occur.

The contingency measure for premature failure of the LCS is the early installation of the perimeter drain system. This will protect the Shallow Aquifer and surface water.

Investigations will be initiated if the leachate level measured in any riser pipe of the LCS exceeds one metre above the invert of the corresponding collection pipe. The investigation will consist of a detailed review of the LCS performance such as leachate levels in riser pipes over time, and of records of pipe inspections. If an isolated failure of a collection pipe or pipes is indicated, remedial action such as the cleaning or rehabilitation of individual collection pipes may be undertaken. If progressive deterioration of the collection system is indicated that is beyond repair or maintenance, then the implementation of contingency measures will be initiated.



~ Failure of Perimeter Cut-off Wall

Failure of the perimeter cut-off wall would cause an increase in groundwater flow towards the Landfill. Providing the LCS could handle the increased groundwater flow, impacts to the Shallow Aquifer should not occur but the volume of leachate to be managed would increase. A failure of the cut-off wall may, however, cause a failure of the LCS by overloading the system with groundwater flow. This would result in the first failure scenario in which the direction of groundwater movement is outward.

The contingency measure for failure of the cut-off wall will be to renovate the existing cut-off wall or install a new cut-off wall. The need to implement the contingency measure will be based on the degree of failure of the cut-off wall.

Investigation will be initiated if the difference in water level elevations in monitoring wells installed on either side of the cut-off wall decreases to 50% or less of the historical differences.

A number of proposed wells (BH23 to BH27) will be established on the landfill side of the cut-off wall and immediately outside of the cut-off wall (BH17 to BH22).

The investigation triggered will involve a detailed review of historical data and, probably, additional piezometer installations on either side of the cut-off wall in the vicinity of the suspected failure area for intensified water level monitoring. If failure of part or all of the wall is confirmed and if the increased flows to the LCS cannot be tolerated, then the contingency measure of renovation or replacement of the wall will be implemented.

Combined Failure of both LCS and Perimeter Cut-off Wall

A combined failure of the perimeter cut-off wall and the LCS would likely cause impacts to the Shallow Aquifer and, possibly, to surface water. Leachate levels in the Landfill would mound causing groundwater flow to be directed outward into the Shallow Aquifer and surface water.

The contingency measure for this failure scenario would be the construction of a groundwater interceptor trench downgradient of the Landfill or the re-establishment of a perimeter cut-off wall combined with a perimeter drain system.

The trigger criteria associated with this combined failure scenario and the initiated investigations would be the same as for the individual failure scenarios described above.


Page 27 o/42 Ontario

With regard to potential deterioration of groundwater quality in the Shallow Aquifer, the compliance locations are as follows: BH17c, BH18c, BH19c, BH20c, BH21a, and BH 22c.

Trigger concentrations for these monitors are given in Table C.3.

Dichloromethane (µg/L) 50 03 12.5

Benzene (µg/L) 5 03 1. 25

Vinyl Chloride (µg/L) 2 03 0.5

Notes: 1 - for the Lower Aquifer 2 - for the Shallow Aquifer 3 - for both the Lower and Shallow Aquifers 4 - trigger concentrations are set at the corresponding

RUPO 5 - the list of trigger parameters could be revised in

the future subject to the Regional Director's approval.

Exceedances of any of trigger levels at any of compliance locations during two consecutive sampling rounds will initiate investigations similar to those as for the individual failure scenarios.



3.2 Pathway 2 Contingency

~ Premature Failure of the Leachate Collection System (LCS)

A premature failure of the LCS will result in increased mounding of leachate in the waste sooner than anticipated. The increased mounding may result in downward groundwater flow. Contaminant transport modelling predicts that, if the LCS fails prematurely (i.e., before 30 years), concentration increases will not rise substantially and impacts would still be below that allowed by the Reasonable Use Guideline. This analysis is conservative in that concentrations are predicted 5 metres below the landfilling area when in reality there is significantly more silt and clay present above the Lower Aquifer. Furthermore, impacts to the Lower Aquifer may not be detectable because of a diluting effect that the Lower Aquifer would have on any contaminant entering the aquifer system.

Because compliance with the Reasonable Use Guideline is predicted for the Lower Aquifer under this failure scenario, a contingency measure to protect the Lower Aquifer is not required. However, confirmation of such a failure by investigations initiated by Pathway 1 trigger criteria may lead to the early installation of the perimeter drain, as discussed previously.

~ Different Movement of Contaminants Than Predicted

The prediction of contaminant movement is based on the current understanding of the hydrogeological regime, as developed by site investigations. The Silt & Clay Unit is expected to play a major role in the protection of the Lower Aquifer. Downward contaminant movement from the Landfill is affected by the hydraulic conductivity of this unit. Impact predictions by contaminant transport modelling are based on a hydraulic conductivity value of 5 x 10-0 cm/s for the Silt & Clay Unit determined from testing.

If the actual vertical hydraulic conductivity of the Silt &

Clay Unit is higher than anticipated, the impacts below the Landfill while the LCS is operating, would actually be less than predicted, as the upward groundwater flow velocity will be higher.

Higher than anticipated vertical hydraulic conductivity values will eventually result in higher impacts below the Landfill once the LCS has failed.


Page 29of42 Ontario

The Lower Aquifer's compliance locations are as follows: BH17a, BH18a, BH19a, BH20a, and BH22a. Trigger concentrations are given in Table C.3. Exceedances of any of trigger levels at any of compliance locations during two consecutive sampling rounds will initiate consideration for the necessary contingency measure implementation(s).

There are two possible contingency measures for this failure scenario. The preferred measure at this time is the installation of the perimeter drain at a lower elevation than would otherwise be the case. The elevation would be established to prevent or reduce a downward hydraulic gradient as opposed to preventing an outward hydraulic gradient. This would reduce the potential for impact on the Lower Aquifer. Alternatively, a purge well system could be installed in the Lower Aquifer, downgradient of the site. This contingency measure should not be implemented unless impacts are actually detected in the Lower Aquifer. Premature contingency pumping from the Lower Aquifer would increase the downward gradient.

3.3 Contingency Implementation

Prior to implementation, any contingency measure(s) shall be discussed with and approved by the Director.

TRIGGER AND CONTINGENCY

Station Bat the outlet of the surface water management pond will be the trigger location for surface water.

Any parameter of Table E.1 with the established PWQO will be used as a trigger parameter. The list of trigger parameters could be revised in the future subject to the Regional Director's approval.

For parameters with background concentrations below the PWQO, trigger levels will be set at the corresponding PWQO. For parameters with background concentrations above the PWQO, trigger levels will be set at the corresponding background concentrations.

If the trigger concentration of any parameter is exceeded at Station B on two consecutive sampling events, an additional sample will be taken to confirm the analysis. If it is determined, based on a review of all of the surface water and groundwater quality data, that the exceedance is related to the Landfill, then contingency measures will be implemented. The nature of the contingency measures will depend on the cause of the problem. For example, if the exceedance results from leachate seeps through the cover, then the contingency measure will be the repair of the cover. If the source of the problem is discharge of contaminated groundwater to surface water, then the appropriate contingency measure for leachate control will be implemented.

CONTINGENCY IMPLEMENTATION

Prior to implementation, the appropriate contingency measure(s) shall be discussed with and approved by the Director.

SUBSEQUENT MODIFICATIONS

If there is any future need to modify the surface water monitoring plan and/or trigger mechanism, a formal application shall be made by the Corporation to the Regional Director requesting his/her approval of the necessary changes and these changes may not be made without such approval.



SCHEDULE "F"

This Schedule "F" forms part of Provisional Certificate of Approval No. A 420,009. It describes the landfill gas monitoring program referred to in Condition 42.

• to monitor combustible gas concentration in on-site buildings.

2 . MONITORING PLAN

The landfill gas monitoring plan shall be carried out by the Corporation to address the stated objectives and shall include the following:

,, 2.1 Gas Monitors

Gas monitors to be sampled are shown on Drawing C.2 of Item 4, Schedule "A".


Gas probes referred to in 2.1, shall be sampled semi-annually, in January and July, using a portable combustible gas detector.

2.3 Sample Analysis

The collected samples shall be analyzed for combustible gas concentration (field instrument calibrated to methane).



3. TRIGGERS AND CONTINGENCIES

At this concentration level, further investigations will be performed to determine cause of exceedance and determine potential impacts to on and off site properties. For example, a possible cause for an exceedance could be a defect in the cut-off wall allowing the passage of landfill gas. At the 20% LEL level, any necessary remedial measures will be undertaken. In the case of the cut-off wall with a defect, repairs to the cut-off wall will be made, if needed.

Prior to implementation, the appropriate contingency measure(s) shall be discussed with and approved by the Director.

4. ADDITIONAL MONITORING

Landfill gas monitoring in on-site buildings shall be carried out by the Corporation in accordance with the procedures outlined in Item 2, Schedule "A".
