3 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA Executive Summary This Noise Existing Conditions Report was prepared to identify and describe the existing noise conditions associated with the Clean Harbors Lambton Landfill Expansion Environmental Assessment Study Area in accordance with the Air Quality, Odour and Noise Work Plan. As per the approved Terms of Reference, the Study Area includes the existing site as well as potentially affected surrounding areas. The Study Area for the noise discipline was defined by the area extending 1 kilometre from the existing Clean Harbors Canada Inc. property boundary and the proposed south expansion alternative. The noise impact beyond 1 kilometre is environmentally insignificant. The noise existing baseline conditions were determined using the framework provided in the approved Terms of Reference. The noise existing conditions were evaluated using predictive modeling and the predominant off-site environmental noise sources were identified. Vehicular road traffic was determined to be the predominant background noise in the Study Area. Field observations were used to confirm the on and off-site baseline conditions as well as the locations of the residential dwellings subject of analysis. The traffic volumes and corresponding traffic-generated sound levels demonstrate that a portion of the Study Area can be classified as Class 2 Urban for those residences located along Petrolia Line and Brigden Road (adjacent to Plank Road). The Study Area can be classified as Class 3 Rural for those residences located along Telfer Road and Rokeby Line due to the absence of significant road traffic volumes. Vibration was observed to be environmentally insignificant. The facility s existing noise levels meet the Ministry of the Environment noise limits at all residential receptors with the exception of one residential property. Noise control measures are necessary to achieve the minimum MOE noise limits at the residence identified as point-of-reception 1. This residence is located immediately west of the Clean Harbors facility main gate on the opposite side of Telfer Road. There are 15 existing one-storey (1.5 m above grade) and two-storey (4.5 m above grade) residential dwellings within the Study Area of interest. D06 - Noise Existing Conditions Report.Docx

6 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA 1.0 Introduction This report identifies and describes the existing noise conditions associated with the proposed expansion of the Clean Harbors Lambton Landfill Expansion Environmental Assessment Study Area (see Section 2.0) in accordance with the approved Terms of Reference (ToR) (Appendix A) and the Air Quality, Odour and Noise Work Plan (Appendix B). The ToR included a preliminary description of the existing environmental conditions in the Study Area with the commitment that the description would be expanded upon in the Environmental Assessment (EA). In accordance with the ToR, investigative studies of the following environmental components were carried out for the purposes of generating a more detailed description and understanding of the existing environment for use in the assessment and evaluation of the two alternative landfill expansion options during the EA: Atmospheric Environment Geology and Hydrogeology Surface Water Natural Environment Agriculture Archaeological and Cultural Heritage Technical Socio-economic Upon completion, each report will be made available during the EA to St. Clair Township and appropriate review agencies, First Nations and Métis organizations, and the public for their information via the project website and upon request and will become either a reference or supporting document to the submitted EA Report.

7 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA 2.0 Clean Harbors Lambton Landfill Expansion Study Area The existing approved landfill operation, including all historical fill areas, has a footprint of 56 hectares out of the entire 121 hectare licensed property (see Figure 2.1). As documented in the ToR, two landfill expansion options for the existing Lambton Landfill have been identified: A vertical expansion of the existing landfill site Expansion of the site to the south of the existing landfill (i.e., shallow entombment off site) As per the ToR, the study areas include the existing Lambton Landfill Facility as well as potentially affected surrounding areas. (See Figure 2.1). The Study Area for the noise discipline was defined by the area extending 1 kilometre (km) from the existing Clean Harbors Canada Inc. (Clean Harbors) property boundary and the proposed south expansion alternative. The Ministry of the Environment (MOE) Noise Screening Process Questionnaire requires that industries with significant noise sources or equipment with significant noise emissions evaluate the off-site environmental noise impact within 1 km from the site; the noise impact beyond 1 km is expected to be environmentally insignificant. Five roadways are located within the Study Area including: 1. Petrolia Line is a two-lane roadway with significant 24-hour road traffic 2. Plank Road (Country Road 20) is a two-lane arterial road to Sarnia with significant 24-hour road traffic north of Petrolia Line 3. Brigden Road is a two-lane road providing access to Country Road 20 with significant 24-hour road traffic 4. Rokeby Line is a two-lane rural road with local traffic only 5. Telfer Road is a two-lane rural road primarily used by Clean Harbors The rationale for the Study Area for the noise discipline is that the off-site environmental noise impact from the existing Clean Harbors Lambton facility (Facility) or the development of either of the two proposed landfill expansion alternatives will be defined by the sound power generated by the equipment on-site and the proximity and line-of-sight exposure to the off-site receiver locations. In the absence of other developments and built structures, such as businesses or institutions, the residential dwellings within the Study Area represent the receiver locations subject of the assessment. The net change to the noise impact predicted at these residences based on the design of the two landfill expansion alternatives will be directly compared to the Noise Existing Conditions Report.

9 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA 3.0 Methodology The Noise Existing Conditions Report was developed based on the evaluation criteria, indicators and data sources included in the approved ToR (refer to Appendix A), which were developed in consultation with government agencies and other stakeholders, and is based on the activities described in the Air Quality, Odour and Noise Work Plan (March, 2011) (refer to Appendix B). In addition, input and comments were solicited from St. Clair Township and First Nations with respect to the Air Quality, Odour and Noise Work Plan. Comments that resulted in revisions to the work plan have been integrated in the description of the existing noise conditions. 3.1 Available Secondary Source Information Collection and Review Available secondary sources of information were collected and reviewed by the Noise Study Team to determine the noise existing conditions within the Study Area. The following sources of information were collected and reviewed: Review of Historic Noise Complaints Review of current zoning plans, definitions and land use designations MOE technical guidelines and standards Road traffic volumes Site visit, field observations and updated noise measurements 3.2 Process Undertaken Information was compiled and interpreted from the secondary source information. The following section outlines the process followed to determine the existing noise conditions Review of Available Information Historic noise complaints, zoning information and road traffic data were collected and reviewed by the project team. The zoning information is summarized in Figure 3.1 and road traffic data is provided in Appendix C. D06 - Noise Existing Conditions Report.Docx - 4 -

11 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA Site Visit & Field Investigations A site visit was necessary to conduct sound level measurements both on and off-site. Field observations were used to confirm the baseline or ambient background noise conditions, the locations and character of the off-site sensitive and/or historic buildings and structures subject of the analysis, and to determine the predominant on-site environmental noise sources Road Traffic Modelling Road traffic volumes for the roads of interest were obtained from the Township of St. Clair and the County of Lambton and input into an industry standard acoustic model. The road traffic noise model was used to approximate the existing baseline or background noise conditions within the Study Area Noise Modelling of the Existing Site Conditions The existing noise conditions at the Clean Harbors Lambton Landfill Facility were evaluated using both direct measurements and predictive modelling. For the purposes of the Noise Existing Conditions Report, the Clean Harbors Lambton Landfill Facility on-site noise sources were measured during worst-case operations and the source parameters were documented including: Type (point or area) Geometry (location, height above grade) Acoustic character (steady state, impulse, tonal) The existing noise sources at the Clean Harbors Lambton Landfill Facility were input into an industry standard acoustic model that included all significant on-site structures (buildings, equipment, storage tanks and silos). The off-site environmental noise from the existing site conditions was predicted based on the measured sound pressure levels and reference distances and representative noise specifications for standard mobile equipment such as trucks and bulldozers. Computer Aided Noise Abatement Acoustical Modeling Software (CADNA A), version 4.3, calculates sound level emissions based on the ISO standard "Acoustics Attenuation of Sound During Propagation Outdoors Part 2: General Method of Calculation". The CADNA model is the industry standard for environmental noise modeling in Ontario. The Ministry s Ontario Road Noise Analysis Method for Environment and Transportation (ORNAMENT) software is the approved road traffic model that is currently used in the province of Ontario to evaluate noise generated from road traffic. However, the model does not graphically generate contours and cannot be used to evaluate large areas and multiple road corridors simultaneously. ORNAMENT modeling predictions are also limited to noise predictions less than 500 metres from the source and a minimum traffic volume of 40 vehicles per hour is required to evaluate an individual roadway. Due to these limitations, CADNA was selected for the purposes of this study as the preferred modeling software for analysis of road traffic generated background noise existing conditions. In D06 - Noise Existing Conditions Report.Docx - 6 -

12 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA addition, the CADNA modeling software is better suited to handle multiple noise sources and can generate contour plots with imported base maps. CRA completed a sensitivity analysis comparing ORNAMENT to CADNA results and concluded that the results obtained using CADNA are more conservative (lower) even when the impact from multiple road segments is modelled. In addition, CADNA can better calculate sound propagation based on surface reflection and ground absorption qualities, changes due to posted speed limits and road geometry. To illustrate this, CRA completed an ORNAMENT model for select receptors that are within 500 m of the major roads within the Study Area. Only roads with traffic volumes over 40 vehicles per hour were modelled due to this minimum traffic volume limitation of the ORNAMENT model. The following table summarizes the CADNA and ORNAMENT model results to illustrate the noise impact comparison: Receptor ORNAMENT Impact CADNA Impact (dba) (dba) POR POR For both receptors, only the impacts from Petrolia Line were estimated. All other roads are located beyond ORNAMENT s 500 m maximum distance limitation and could not be modelled. In addition, traffic along the smaller connecting roads is below ORNAMENT s 40 vehicles per hour limitation and as such their impacts could not be modelled. However, CRA created an illustrative model where the road segments of interest (Petrolia Line, Plank Road and Rokeby Line) were within the 500 m ORNAMENT limit and the traffic volumes were also above the 40 vehicles per hour limit. This hypothetical scenario was created to support the sensitivity analysis and the results are not representative of the ambient conditions but provided for information purposes only. The following model inputs were used: Petrolia Line o Total hourly traffic volume 150 vehicles/hour o Traffic breakdown percentage (auto/medium/heavy) 55/35/10 o Speed Limit 80 km/h o Distance from receptor 300 m Plank Road o Total hourly traffic volume 200 vehicles/hour o Traffic breakdown percentage (auto/medium/heavy) 55/35/10 o Speed Limit 80 km/h o Distance from receptor 250 m Rokeby Line o Total hourly traffic volume 100 vehicles/hour o Traffic breakdown percentage (auto/medium/heavy) 55/35/10 o Speed Limit 80 km/h o Distance from receptor 250 m D06 - Noise Existing Conditions Report.Docx - 7 -

13 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA The results from the noise model are summarized in the table below: ORNAMENT CADNA (dba) (dba) As shown, the road traffic noise impacts estimated by the CADNA software are consistently more conservative. Therefore the use of the CADNA model with the TNM module is considered to be representative of the typical ambient conditions within the Study Area. The road traffic data and modelling methodology is explained in Section Review of Noise Work Plan Comments were solicited from St. Clair Township, First Nations, and the Ministry of the Environment on the Noise Existing Conditions Work Plan. A copy of the Work Plan is included in Appendix B. Comments that resulted in revisions to the Noise Existing Conditions Work Plan have been integrated in this report and are outlined in Table To review all comments received on the various Work Plans and associated Clean Harbors responses, please refer to the Clean Harbors Work Plan Comment Response Summary Report. Note that this Report will also be documented in the Environmental Assessment Record of Consultation. Table Work Plan Revisions Based on Comments Received Reviewer Comments Clean Harbors Response Existing Conditions Report Reference St. Clair Township It appears that very little will be done as part of the existing noise conditions evaluation. Some measurements may be undertaken to fill in the gaps in the information already on hand or contained within previously prepared Acoustic Assessment Reports (AAR). As noted in PRT Comment #1, the information that is already on hand and what the gaps are must be clearly outlined. The current TDU AAR reflects the existing conditions and measurements are not necessary to update the AAR detailing the stationary noise sources. Updated sound level measurements were conducted in October See Section 4.6. D06 - Noise Existing Conditions Report.Docx - 8 -

14 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA 4.0 Existing Noise Conditions 4.1 Historic Noise Complaints Clean Harbors has not received any noise complaints for the existing operations. Additionally, members of the surrounding community were surveyed on a number of issues, including concerns related to noise. When asked if there are any concerns related to dust, odour or noise from the facility, a greater number of respondents stated that they have these types of concerns than the number of people that have filed complaints about the existing site. These responses are summarized in Table 4.1 below. Table 4.1 Summary of Residents and Business Survey Responses Regarding Concerns about the Clean Harbors Lambton Facility Type of Concern Yes No Total Number of Responses Dust from the Air Odour Noise When asked to explain these concerns in more detail, residents gave a range of answers including health concerns, general unpleasant nuisance effects and concerns from the noise of Clean Harbors operations and from truck traffic. This suggests that while fewer respondents stated that they have filed complaints about the site, a greater number of respondents do have concerns about the existing facility, when specifically asked. This is particularly the case with respect to odour. This information is also available in more detail in the Socio-Economic Existing Conditions Report. 4.2 Review of Zoning The Clean Harbors Facility is located on Industrial zoned land (M4-1) and is surrounded by land that is zoned for Agricultural use (A1) and Environmental Protection Woodlot (EP-WD) zones. The Study Area is rural in character and surrounded by agricultural fields. There are no existing industries within the Study Area other than the existing Clean Harbors Facility that contribute to the background noise levels. 4.3 Site Visit and Field Investigation Site visits and field investigations were conducted on October 4, 2012, and October 27, The purpose of the field investigations were to: 1) identify the predominant background ambient noise source(s) 2) confirm the character of existing buildings and off-site receiver locations subject of the noise impact assessment 3) classify the acoustic character of the Study Area D06 - Noise Existing Conditions Report.Docx - 9 -

15 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA 4) conduct updated sound level measurements for, and to identify, the predominant on-site environmental noise source(s) Road traffic noise was the predominant source of ambient noise in the Study Area based on a review of the available secondary information and observations during the site visits and field observations. Road traffic noise impacting the receptors within the identified Study Area is generated by vehicles travelling along the following corridors: Petrolia Line Plank Road Brigden Road Telfer Road Rokeby Line The background noise generated from vehicles travelling these five roads of interest was evaluated. There are both one and two-storey residential dwellings of varied construction (siding, brick) located along these roads. Aside from outbuildings servicing farm equipment and related storage, there are no other significant developments or businesses located within the Study Area. The acoustical character of the Study Area was evidently a mixed rural and suburban environment. The background noise or ambient sound is dominated by road traffic or natural sounds depending on proximity to the adjacent road corridors and the extent of their use as defined by the 24-hour traffic volume. A detailed description of the Study Area is provided in the following Section 4.5. The noise measurements and the predominant on-site environmental noise sources are discussed in Section MOE Technical Guidelines and Standards The acoustic character of the Study Area will be defined in accordance with the MOE guidelines NPC Stationary and Transportation Sources Approval and Planning, October As stated in the guidelines: A "Class 1 Area" means an area with an acoustical environment typical of a major population centre, where the background noise is dominated by the urban hum. "Class 2 Area" means an area with an acoustical environment that has qualities representative of both Class 1 and Class 3 Areas, and in which a low ambient sound level, normally occurring only between 23:00 and 07:00 hours in Class 1 Areas, will typically be realized as early as 19:00 hours. D06 - Noise Existing Conditions Report.Docx

16 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA Other characteristics which may indicate the presence of a Class 2 Area include: Absence of urban hum between 19:00 and 23:00 hours Evening background sound level defined by natural environment and infrequent human activity No clearly audible sound from stationary sources other than from those under impact assessment "Class 3 Area" means a rural area with an acoustical environment that is dominated by natural sounds having little or no road traffic, such as the following: A small community with less than 1000 population Agricultural area A rural recreational area such as a cottage or a resort area A wilderness area The urban sound level limits are 5 dba greater in comparison to the rural limits to account for the elevated background sound level or the urban hum due to road traffic or adjacent industrial/commercial activities. 4.5 Road Traffic Data and Modelling Road Traffic Volumes The most current road traffic volumes were provided by the following authorities: Township of St. Clair The County of Lambton The road traffic data provided by the Township of St. Clair included actual daily counts for the following roads within the Study Area: Rokeby Line (2009) Plank Road (south of Petrolia Line) (2009/2011) Brigden Road (2002) The road traffic data that was provided by the County of Lambton was inclusive of the existing site truck traffic and included an hourly breakdown, as well as traffic distribution, for the following roads within the Study Area: Petrolia Line (2011) Plank Road (north of Petrolia Line) (2011) The traffic volume data discussed above was the only available data for the Study Area. Telfer Road traffic was not available. The Noise Study Team has observed that the road is used primarily for access to the Clean Harbors site. D06 - Noise Existing Conditions Report.Docx

17 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA Annual Average Daily Traffic (AADT) values are the only reported data for less travelled roads, which presents a problem when estimating daytime and nighttime background noise levels as the values do not provide a distribution for the two time periods. Detailed information was provided for the two major roads Petrolia Line and Plank Road (north of Petrolia Line). This information included a detailed traffic breakdown for each hour of the day as well as traffic distribution, which provides information on the types of vehicles. The AADT provided for each road was: Petrolia Line (west of Plank Road) 2,340 Plank Road (north of Petrolia) 4,029 Rokeby Line 214 Plank Road (between Petrolia and Waterworks) 425 Brigden Road 1,998 To estimate the daytime and nighttime road traffic volumes for the less travelled roads, the 24-hour traffic pattern for the two major roads was used. The 24-hour traffic pattern was determined by calculating the average hourly traffic volumes for the daytime and nighttime periods along Petrolia and Plank Road as well as calculating the average breakdown of automobiles, medium trucks and heavy trucks for each time period. The pattern was then converted to a percentage, which allowed for the direct conversion of the AADT values to estimate the average hourly volumes for those roads where 24-hour detailed traffic data was not available. This was considered to be the most representative approach to evaluate the typical traffic noise exposure for the Study Area. The following hourly traffic composition (rounded to the nearest full number) was estimated: Petrolia Line: o Hourly Daytime Automobile Percentage of traffic 53% o Hourly Daytime Medium Truck Percentage of traffic 38% o Hourly Daytime Heavy Truck Percentage of traffic 10% o Hourly Nighttime Automobile Percentage of traffic 47% o Hourly Nighttime Medium Truck Percentage of traffic 47% o Hourly Nighttime Heavy Truck Percentage of traffic 6% Plank Road o Hourly Daytime Automobile Percentage of traffic 67% o Hourly Daytime Medium Truck Percentage of traffic 30% o Hourly Daytime Heavy Truck Percentage of traffic 3% o Hourly Nighttime Automobile Percentage of traffic 62% o Hourly Nighttime Medium Truck Percentage of traffic 35% o Hourly Nighttime Heavy Truck Percentage of traffic 3% Again, the percentages were then applied to the calculated average daytime and nighttime volumes for the smaller, connecting roads. The resulting numbers allowed CRA to estimate the road traffic noise impacts on an hourly basis for a direct comparison to Facility-generated noise impacts. Traffic distribution plays a vital role in estimating the background noise levels due to traffic. Larger vehicles, such as buses and tractor trailers are noisier than passenger vehicles due to the use of larger engines, reduced aerodynamics associated with frontal surface area, and tire noise associated with larger tires with deeper treads and a heavier load. D06 - Noise Existing Conditions Report.Docx

18 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA CRA reviewed the itrans Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment, dated September 2009 (itrans Report), however, did not use the presented traffic data to evaluate the ambient noise due to road traffic within the Study Area. The itrans Report focused on evaluating only the peak hourly traffic volumes during the daytime and evening, which if used will result in higher ambient noise and not representative of typical traffic noise exposure for the Study Area. In addition, as outlined above, CRA obtained more up-to-date traffic data from the local traffic authorities and did not apply a growth factor to be conservative. CRA did use the on-site truck traffic counts from the itrans Report to model a typical truck traffic conditions model for comparison to the worst-case existing conditions, which is discussed in Section 4.6. The existing noise conditions within the Study Area were quantified using the industry standard CADNA software and the road traffic data provided by the regulatory authorities. The US Department of Transportation Federal Highway Administration Traffic Noise Model (TNM) calculation standard was used in CADNA to quantify the noise levels. Vehicular road traffic generates noise that consists of mechanical noise from the engine and brakes, friction noise created from wheel contacting the road surface, and aerodynamic wind noise. Traffic volume, speed, road composition, gradient and surface type will affect the overall traffic noise that can be generated. Proximity and line-of-sight to the road corridor are most consequential for quantifying the off-site noise exposure conditions. The model calculates the predicted equivalent sound level (Leq) respective of the defined daytime (7 am to 11 pm) and nighttime (11 pm to 7 am) periods Model Input Parameters Site-specific conditions were input, including the width of each road segment, the road surface composition type, the basic site topography, the ground surface type, road traffic volumes and composition, and the posted speed limits. Satellite imagery was obtained and input to the model. The files included major topographic features such as roads, intersections, and lots, which were necessary to establish basic site geometry for modeling purposes. The following critical road traffic noise modeling parameters were identified for the Study Area: 1. Traffic Volumes 2. Road Conditions 3. Vehicle Distribution Traffic Volumes Hourly traffic patterns for the two main roads were used to estimate the daytime and nighttime traffic volumes for less travelled roads, for which only AADT values were provided. D06 - Noise Existing Conditions Report.Docx

19 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA The traffic volumes input determine the potential sound energy generated by each road corridor Road Conditions Road conditions are necessary to accurately model the noise propagation from the vehicles travelling along the defined corridors. The following information was input: 1. Width of Road establishes source geometry and that the sound propagation begins over a reflective pavement surface. 2. Surface Type reflective or porous ground was established for both the road and non-road surfaces, respectively. 3. Speed Limit the posted speed limit was input for each roadway. The posted speed limit of each road plays a vital role in determining the noise dispersion due to the effects of the engine, tire noise and aerodynamic noise generated at different speeds. The Township of St. Clair provided average recorded speeds which were higher than the posted speed limits. The posted speed limits throughout the Study Area were used for the CADNA model results as the average recorded speed may differ between different sampling periods Road Traffic Modelling Results The CADNA modelling software was used to predict the road traffic generated ambient sound levels within the Study Area. The sound level contours provide a visual representation of the traffic generated noise and how it propagates with greater distance from the road corridor. As expected, major roads, such as Brigden Road, Petrolia Line and Plank Road experience greater 24-hour road traffic volumes and are the predominant contributors to the background noise levels within the Study Area. The nighttime noise levels are lower than the daytime levels due to the significantly lower traffic volumes. Figures 4.1 and 4.2 present the road traffic sound level contours within the Study Area for the daytime and nighttime periods, respectively. Daytime noise impacts at the off-site residences varied from 29 dba to 52 dba and from 24 dba to 48 dba during the nighttime, depending on their proximity to the modelled roads. The noise modelling results were verified through field observations conducted on October 4, The traffic generated sound levels demonstrate that a portion of the Study Area can be classified as Class 2 Urban for those residences located along Petrolia Line and Brigden Road (adjacent to Plank Road). The Study Area can be classified as Class 3 Rural for those residences located along Telfer Road and Rokeby Line due to the absence of significant road traffic volumes. This classification was previously agreed to by the MOE in 2010, including the analysis of independent consultants, and was further confirmed during the preparation of this report.

22 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA 4.6 Noise Model of the Existing Facility Conditions Field Investigations The off-site environmental noise impact from the Facility was previously documented in a December 2009 Acoustic Assessment Report (AAR) that was submitted and approved by the MOE in support of a Certificate of Approval (Air) Application, now termed an Environmental Compliance Approval (ECA). Updated sound level measurements were obtained for the environmental noise sources during the field investigations that were conducted on October 4th, and 12th, All noise measurements were conducted in accordance with good acoustic engineering methods and in consideration of the MOE equipment and procedural requirements as defined in NPC-103 Procedures Predominant Noise Sources The model included all environmental or outdoor noise sources that were identified at the Facility. The significant environmental noise sources are summarized in Table 1 in Appendix D. The predominant off-site environmental noise sources are summarized as follows: Incineration and Disposal Facility 1) Incinerator Stack 2) Landfill Disposal Regulation (LDR) Stack 3) Incinerator Primary Combustion Air Blower and Fan Assembly Landfill Operations 4) Main On-site Truck Route The environmental noise sources generate continuous steady state mechanical noise. There are no ground-borne vibration sources at the Facility. As stated in the approved ToR, there are no anticipated effects to warrant noise model analysis of the off-site haul route, which will be unchanged from the existing conditions to the proposed alternatives. A traffic impact study was completed as part of the approved ToR. The study concluded that the existing study area road network and intersections have sufficient reserve capacity to accommodate the projected growth in background traffic along with the truck traffic associated with the continued operation of the landfill operations at the Lambton Facility. The projected traffic volumes and access arrangements will not vary between the two alternative landfill expansion alternatives under consideration and thus traffic would not be used as a criterion in the comparative evaluation of alternatives. D06 - Noise Existing Conditions Report.Docx

23 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA Modelled Noise Contours The environmental noise model in support of the Facility s AAR was based on the principal of the predictable worst-case, meaning the model evaluates the on-site activities that generate the maximum noise level in terms of the 1-hour equivalent sound level (1-hour Leq). The Facility will not be operating continuously under a worst-case scenario. Therefore, CRA developed a second typical noise model based on the on-site truck traffic data as provided in the itrans 2009 Report. The difference between the two scenarios is the number of trucks entering, leaving and driving within the Facility boundary. The results of the worst-case and typical scenarios represent the existing conditions noise exposure range. As per the itrans Report, the peak AM truck traffic is 2 trucks entering the site and 1 truck leaving the site. To model this typical scenario, CRA assumed that the only trucks entering and leaving the site are landfill trucks. All other truck routes, such as incinerator and fly ash routes were not included in the model because the traffic on-site did not permit their inclusion. The noise model included attenuation affects due to geometric divergence, atmospheric attenuation, barriers/berms, ground absorption and directivity, as applicable for all significant noise sources. The on-site buildings were input as intervening and reflective structures at the appropriate height. Ground contours were also input to the model. The existing unattenuated steady state noise levels for the worst-case and typical scenarios are presented as contours, which propagate and decay with increased distance from the source and are presented on Figure 4.3A to Figure 4.4B for the day and night, respectively. The modelled noise exposure range based on the two scenarios is 0.7 db at POR1, which is the receptor most impacted by truck traffic due to line-of-sight noise exposure. The reason for the small difference is that the unattenuated stationary noise sources are the compliance drivers and as such, a reduction in the truck traffic has little environmental effect. The attenuated steady state noise levels (post 2020 Phase 3 abatement completion) are presented for both the worst-case and typical scenarios on Figures 4.5A to Figure 4.6B for the daytime and nighttime, respectively. The modelled noise exposure range for the attenuated steady state noise levels is 4.7 db for POR1, which is the receptor most heavily impacted by truck traffic. Once attenuated, the off-site stationary noise source impacts are lower and therefore, truck traffic has a higher impact at this receiver only. D06 - Noise Existing Conditions Report.Docx

32 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA Off-site Noise Impact at Existing Receivers There are 14 existing one-storey (1.5 m above grade) and two-storey (4.5 m above grade) residential dwellings within the Study Area of interest. The December 2009 AAR documented the off-site impact at four of the immediately adjacent and most exposed sensitive point(s)-of-reception(pors). A "POR" is any point on the premises of a person where sound, originating from other than those premises, is received. The POR may be located on permanent or seasonal residences, hotels/motels, nursing/retirement homes, rental residences, hospitals, campgrounds, parks, schools, or places of worship. The off-site environmental noise impacts from all the steady state sources and impulse noise sources are summarized in Table 2 and Table 3, respectively, in Appendix D. The off-site noise impacts are summarized against the applicable MOE criteria in Table 4 (Appendix D). The attenuated off-site impacts confirm that the receptors located beyond the Study Area will experience insignificant environmental impacts to justify the 1 km Study Area radius. The Facility attenuated noise impacts were compared against the higher of the minimum exclusionary MOE noise limits or site-specific sound level limits established in accordance with NPC-300. The Landfill operations are compared against the daytime limit of 55 dba with operations limited to 7 a.m. to 7 p.m. under the Noise Guidelines for Landfill Sites (N-1). The Facility s noise levels meet the MOE NPC-300 noise limits at all receptors pending the completion of the 2020 Phase 3 Noise Abatement Plan (NAP). The updated AAR and NAP are subject of MOE review and approval. Implementing the noise control measures is intended to achieve the minimum MOE noise limits at POR1.

33 Noise Existing Conditions Report Clean Harbors Lambton Landfill Expansion EA 5.0 Summary The traffic volumes and corresponding traffic-generated sound levels demonstrate that a portion of the Study Area can be classified as Class 2 Urban for those residences located along Petrolia Line and Brigden Road (adjacent to Plank Road). The Study Area can be classified as Class 3 Rural for those residences located along Telfer Road and Rokeby Line due to the absence of significant road traffic volumes. There are 14 existing one-storey (1.5 m above grade) and two-storey (4.5 m above grade) residential dwellings within the Study Area of interest. The facility s existing noise levels meet the MOE noise limits at all residential receptors with the exception of one residential property. Noise control measures are necessary to achieve the minimum MOE noise limits at the residence identified as POR1. The noise existing conditions for the Study Area are summarized as follows: Steady state noise from the existing Clean Harbors Lambton Landfill Facility Impulse noise generated from the baghouse controls Road traffic noise from Petrolia Line, Bridgden Road, Plank Road, Rokeby Line The existing noise conditions including the steady state noise contribution from the Facility and background road traffic noise are presented on Figure 5.1 below.

48 1.0 INTRODUCTION Conestoga-Rovers & Associates (CRA) has been retained by Clean Harbors to conduct the Air Quality (Air Emissions, Odour and Noise) studies required as part of the Environmental Assessment (EA) for the proposed expansion of the hazardous waste landfill at the Clean Harbors Canada, Inc. Facility (Facility) located in St. Clair Township, Lambton County, Ontario. CRA is intimately familiar with the Facility's air and noise emissions. During the past three years, CRA has successfully completed the following air and noise projects for the Facility: Prepared an Application for Certificate of Approval (C of A) (Air) for the laboratory operation Prepared an Application for C of A (Air) for the proposed SPL waste processing unit Prepared an Application for C of A (Air) for the proposed Thermal Desorber Unit (TDU) Updated the site-wide Emissions Summary and Dispersion Modeling (ESDM) Report, including all air emissions sources at the Facility Prepared a site-wide air dispersion model using the USEPA AERMOD Dispersion model, including fugitive sources Completed a stack testing program for a baghouse emission control system for the pretreatment operation Updated the site s Fugitive Dust Best Management Practices Plan (FDBMPP) Prepared a Compliance Verification Plan (CVP) for the TDU Prepared a Site-wide Additional Noise Assessment and Acoustic Audit Report The following is a detailed work plan for the Air Quality Studies (7) 1 CONESTOGA-ROVERS &ASSOCIATES

49 2.0 OVERVIEW The primary air and noise emission sources at the Facility include: An active landfill area on the north side of the Facility containing working cells A liquid industrial waste incinerator near the centre of the Facility A pretreatment facility near the centre of the Facility A laboratory building near the west side of the Facility A thermal desorber unit (TDU) and associated sources Several fugitive emission sources at various locations There are two designs for the proposed landfill expansion currently under consideration. This proposal is based on the assumption that two "Alternative Methods" (Alternatives) identified in the Terms of Reference (ToR) will be evaluated in the EA: Alternative Method 1 - Vertical Expansion Alternative Method 2 - Shallow Entombment (Southern Expansion) The air quality and noise studies will evaluate both alternatives and will include evaluations of compliance with applicable air quality and noise regulations. The air quality component will evaluate all of the air contaminants emitted from the Facility, including odour. The MOE requires site-wide assessments for the air and noise impacts. Therefore, the air and noise sources associated with activities other than the landfill operations will also be included in the studies. Other sources will include, for example, the incinerator, the TDU, the pretreatment operations and the laboratory. The ToR requires an assessment of cumulative effects for air emissions from other offsite sources. This will be assessed using background air quality data. The ToR contemplates description of existing environmental conditions (including existing/baseline air and noise quality). CRA will build on existing air and noise studies and reports completed for the Facility in the past few years. The air quality and noise studies will require the identification of potential effects by the proposed expansion on those existing environmental (i.e. air and noise) conditions. An evaluation of the potential environmental effects (after mitigation) with regard to air quality, odour and noise impacts will be provided for each of the expansion options and (7) 2 CONESTOGA-ROVERS &ASSOCIATES

50 a technical memo comparing the two options from an air quality, odour, and noise perspective will be provided. 2.1 ESTABLISH EXISTING CONDITIONS The detailed work plan for Establishing Existing Conditions is discussed below: DATA COLLECTION AND ANALYSIS CRA's air quality and noise experts will collect and analyze the necessary background information as per Appendix B of the ToR, including, but not limited to: Environment Canada Sarnia Airport meteorological data MOE meteorological data Sarnia Lambton Environmental Association meteorological data and background air quality Waste materials and leachate characterization and sampling data Noise and odour complaint history Site-specific monitoring data FIELDWORK CRA will conduct some additional fieldwork to fill any gaps in the available air, noise, and odour data. The contemplated fieldwork includes: Noise Data Collection Fieldwork - The noise measurements will evaluate the noise impact and compliance with NPC-232 noise limits by conducting short-term and direct audit sound level measurements. Measurements will be conducted when the Facility is operating under normal conditions. The selected measurement period will be respective of the predictable worst-case when the difference between the Facility noise emissions and background noise conditions are at a maximum, which may require that the audit measurements are conducted during the late nighttime period when human and commercial generated noise is minimized. Odour Fieldwork The odour data collection will involve the use of a Nasal Ranger Field Olfactometer to measure and quantify odor strength in the ambient air (7) 3 CONESTOGA-ROVERS &ASSOCIATES

51 Measurement of odour units will be conducted for the primary fugitive emission sources, including the landfill working face, leachate ponds, and TDU process. Air Fieldwork CRA field staff will collect total hydrocarbon (THC) data using a photoionization detector (PID) to assess the potential fugitive emissions of organic compounds from the landfill working face, leachate ponds and TDU process. Chemicalspecific sampling is not included in this air quality data collection SUMMARY OF EXISTING CONDITIONS To summarize the existing conditions for air, noise, and odour at the site, CRA will provide the 2010 Emission Summary and Dispersion Modelling (ESDM) Report and Acoustic Assessment Report (AAR), prepared in support of an Application for C of A (Air) for the Thermal Desorber Unit (TDU) in addition to the 2010 Annual Report, and supplemental technical memorandums describing the results of the field work outlined above. 2.2 CONDUCT COMPARATIVE EVALUATION OF THE ALTERNATIVES This section provides a description of the detailed work plan involved in the detailed air quality and noise studies that will be required for the evaluation of the two alternatives during the EA AIR QUALITY STUDY The Air Quality Study includes the following three main components: Air emissions estimates for the two options Air dispersion modeling for the two options Reporting, including the estimated air quality and odour impacts from the expansion options at off-site, sensitive receptors (7) 4 CONESTOGA-ROVERS &ASSOCIATES

52 Air Emission Estimates CRA will calculate the air emissions from the two landfill design options. The existing air emissions from other sources at the Facility will also be included. The existing ESDM report will be used for the existing air emissions sources. The potential air emissions from the Facility that will be assessed include: particulate matter (TSP, PM10, PM2.5); combustion by-products including CO, NOx, and SOx; volatile organic compounds (VOCs); polycyclic aromatic compounds (PAHs); carbonyl compounds; dioxins/furans; metals; and odour. Odour will be addressed by modelling odour unit emissions. The Facility's complaint response procedure records include useful qualitative information about the potential for odour impacts from the existing operations. A quantitative odour assessment in terms of odour units (OU) will be conducted based on the field sampling data. The Facility's fugitive dust management plan (FDMP) will be updated to address fugitive dust from the new landfill configuration, once the preferred alternative is identified and has EA approval. Fugitive particulate and odour emissions will continue to be addressed by an effective fugitive dust and odour management program and are not expected to be an issue. There will be one round of Facility-wide emissions estimates for each landfill expansion option. Air Dispersion Modelling The estimated emissions from the Facility will be used as input in an approved air dispersion model to predict off-site concentrations of potential air contaminants. These off-site concentration predictions will be used to compare against the Ontario Regulation 419 air quality standards. CRA will use the USEPA AERMOD dispersion model. AERMOD is an advanced steady-state plume model that has the ability to incorporate building cavity downwash, actual source parameters, emission rates, terrain, and historical meteorological information to predict ground level concentrations (GLCs) at specified locations. Short-term (1-hour average) and long-term (24-hour and annual averages) concentration predictions will be calculated for comparison with the Regulation 419 air quality criteria as applicable (7) 5 CONESTOGA-ROVERS &ASSOCIATES

53 It has been assumed that there will be one round of dispersion modeling for each landfill expansion option. ESDM Reports Updated ESDM Reports will be prepared for both options and will include: A description of the site and the proposed expansion options An assessment of existing background air quality based on existing data Air emissions estimates (including odour) for the landfill expansion options Air emissions estimates (including odour) for the other sources (e.g., TDU) at the Facility Dispersion modelling results, including contour plots Identification of nearby sensitive receptors Assessment of off-site air quality impacts, including odour impacts Conclusions ESDM Reports will be prepared in accordance with the following MOE guidance documents: Procedure for Preparing an Emission Summary and Dispersion Modelling Report (March 2009) Air Dispersion Modelling Guideline for Ontario (March 2009) NOISE STUDY The objective of the Noise Study will be to document and assess the potential noise impact of the Facility's noise sources at the nearest sensitive points-of-reception for the two landfill expansion options. The study will demonstrate that the sound emissions comply with the MOE's applicable sound level limits for the off-site receptors. The Noise Study includes the following three main components: Noise source emission estimates including reference sound level specifications Noise modeling to predict noise levels at off-site sensitive receptors (7) 6 CONESTOGA-ROVERS &ASSOCIATES

54 Reporting, including background sound levels and the estimated noise impacts at the nearest sensitive receptors Noise Emission Estimates The Noise Study will utilize the Facility's AAR. It will include a description of the noise sources, a description of assessment methods, the details of source and background sound level measurements, an assessment of line-of-sight exposure of nearby sensitive point(s)-of-reception to the primary noise sources, and an assessment of compliance with applicable noise criteria. Noise Modelling The Cadna A acoustic software model will be used to predict the off-site noise levels at the nearest sensitive receptors. Cadna is an accepted software by the MOE and it utilizes the standard ISO 9613 calculation procedures for environmental noise impacts. Noise source specifications, building parameters and digital terrain data will be used as inputs to the model. Noise contour plots will be produced and predictions at specific sensitive receptors will be made. One-hour equivalent sound levels (1-hour Leq) will be made for different time periods to compare with applicable noise criteria. The time periods are daytime (7:00 a.m. to 7:00 p.m.), evening (7:00 p.m. to 11:00 p.m.) and nighttime (11:00 p.m. to 7:00 a.m.). To assess compliance of noise source emissions, the noise levels estimated at sensitive points of reception will be compared with MOE applicable sound level criteria. The MOE sound level limits will be used for the determination of compliance. Based on CRA's review of the Facility, the NPC-205 Class 2 criteria should be applicable. If noise abatement is required to meet the MOE's noise criteria, CRA will identify the significant noise source(s) that require mitigation and the required noise attenuation in decibels (dba). AAR An AAR will be prepared for each alternative and will include: A description of the site and the proposed expansion options An assessment of existing background and on-site noise levels (e.g., TDU) (7) 7 CONESTOGA-ROVERS &ASSOCIATES

55 Identification of nearby sensitive receptors Assessment of off-site noise impacts based on the landfill expansion options Conclusions The AAR will be prepared in accordance with the following MOE guidance documentation: "Appendix A Supporting Information for an Acoustic Assessment Report or Vibration Assessment Report Required by a Basic Comprehensive C of A", April 2004" NPC-233, "Information to be Submitted for Approval of Stationary Sources of Sound, October 1995" NPC-103, "Procedures, August 1978" PREPARATION OF TECHNICAL MEMORANDUM CRA will prepare a technical memorandum, summarizing the air quality and noise studies and ranking the alternatives CUMULATIVE EFFECTS ASSESSMENT Using the background air quality data, CRA will conduct a cumulative effects assessment for any contaminants present in significant amounts that are emitted from the facility. The cumulative effects of the facility emissions and background concentrations will be compared against MOE criteria. A technical memorandum will be prepared to discuss the conclusions of the cumulative effects assessment (7) 8 CONESTOGA-ROVERS &ASSOCIATES
