Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment 1. INTRODUCTION The 121-hectare is owned and operated by Clean Harbors Canada, Inc. and is located at 4090 Telfer Road in Lambton County. The facility is bounded by Petrolia Line to the north, Telfer Road to the west and agricultural lands to the south and east. The location of the is illustrated in Exhibit 1. The was initially opened in 1962 as a landfill. Currently in addition to the secure landfill disposal facilities, the site contains offices, an analytical laboratory, a transportation terminal, and also operates a high-temperature liquid incinerator. Clean Harbors has initiated an Environmental Assessment (EA) process to examine the possibility of continuing the operations of the Lambton landfill for a further 25 years with an average annual landfill waste receipt of 170,000 tonnes per annum. As part of this process, Clean Harbors has retained itrans Consulting Inc. (itrans) to undertake a transportation assessment to examine the current and forecasted impact of the traffic generated by the landfill operations on the study area road network. The projected traffic volumes and access arrangements will not vary between the two alternatives proposed for consideration in the Environmental Assessment. Therefore, this assessment can be considered to be common to both alternatives. 1.1 Purpose and Scope The purpose of this assessment is to assess the traffic impacts of the Lambton landfill operations of the facility on the study area road network intersections during the weekday AM and PM peak hours of operation; identify future road network deficiencies; and where necessary, recommend road network improvements to accommodate the future traffic associated with the ongoing operation of the Lambton landfill. The traffic assessment contained herein has been completed for both the existing traffic conditions inclusive of: the landfill operations; the incinerator; the laboratory; the transportation terminal and the supporting employee traffic (herein referred to as Lambton Facility traffic), and for a forecast 25-year time horizon. Through discussions with Clean Harbors, it has been forecast that the 2009 intake for the Lambton landfill will be in the order of 180,000 tonnes; slightly higher than the projected average annual intake of 170,000 tonnes over the next 25 years being considered for the environmental assessment process. As such, the assessment of the existing conditions, inclusive of the Lambton landfill traffic, is considered to be representative of future traffic volumes. September 2009 1 itrans Project # 4411

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment Although the continued operation of the Lambton landfill is not anticipated to increase the current site generated traffic volumes, a high-volume waste-intake sensitivity analysis has been completed as part of this assessment. The high-volume waste-intake analysis takes into account the potential for a significant increase in the waste-intake to the facility over a period of time to determine what; if any, impacts the Lambton landfill site traffic at the higher level of waste intake would have on the operations of the study area intersections. Historical waste receipts for the Lambton landfill from 1986 to 2006 were reviewed to identify the historical peak annual intake of the landfill operations. The maximum annual waste intake of the landfill operations occurred in 1999 with approximately 380,000 tonnes of waste intake. As such, the sensitivity analysis has projected the peak hour Lambton landfill truck volumes that are commensurate with an annual intake of 380,000 tonnes to determine the relative traffic impacts associated with the annual fluctuations of waste intake at the Lambton landfill. It should be noted the sensitivity analysis has been undertaken for annual intake estimates that are over 220 percent (224%) higher than the estimated average annual intake and therefore should be considered as a worst-case scenario. The approved haul routes between Highway 402 and the are illustrated in Exhibit 2. 1.2 Study Methodology The study methodology for the transportation assessment for the continued operation of the Lambton landfill is as follows: A site meeting was held with all consultants for the environmental assessment process to discuss the requirements of the study and data available. A site visit was undertaken to familiarize staff with the study area road network including the approved haul routes and study area intersections between Highway 402 and the. A video log of the study area road network and detailed information about the study area intersections was recorded. Existing traffic counts were obtained from the Ministry of Transportation of Ontario (MTO) and Lambton County. Where current traffic data was not available, updated weekday AM and PM peak period turning movement counts were undertaken by Pyramid Traffic Information Services (Pyramid Traffic) on behalf of itrans. In order to complete the high-volume waste intake traffic assessment, the existing Lambton landfill traffic volumes needed to be isolated from the other site traffic (i.e. incinerator traffic) so that growth rates could be applied to the landfill traffic volumes to reflect an increase in annual waste intake. This was accomplished by recording the liquid transports (destined to the incinerator) and the non-liquid transports (to the landfill) at the intersection of Petrolia Line at Telfer Road. Existing intersection operations were analyzed to determine the baseline conditions. September 2009 3 itrans Project # 4411

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment Annual growth rates determined through discussion with the County of Lambton were applied to the existing traffic volumes (inclusive of the existing Lambton landfill truck traffic) to forecast the 25-year horizon traffic volumes at the study area intersections. Forecasted future intersection operations were analyzed to identify the projected study area road network deficiencies, if any. Historical Lambton landfill truck volumes and landfill waste receipt volumes were analyzed to determine annual, monthly, and day-of-week variations and trends. Distribution of the Lambton landfill truck traffic onto the study area road network was derived based on the observed turning movements at the intersection of Petrolia Line at Telfer Road and carried through the study area road network using first principles based on the approved haul routes to/from Highway 402. A waste intake sensitivity analysis was completed to account for the potential for annual fluctuations in the waste intake of the landfill operations. The sensitivity analysis utilized an annual intake equal to the historical maximum annual intake of 380,000 tonnes, an increase of more than 220 percent of the projected average annual waste intake. The sensitivity analysis of the study area intersection operations can be considered a conservative projection based on peak year, peak month, and peak day-of-week trends to determine a worst-case scenario. Recommendations where necessary to accommodate the future Lambton landfill traffic volumes on the study area road network have been identified. 1.3 Intersection Operations Methodology Intersection operations at the study area intersections noted in Section 2 of this report were assessed using the software program Synchro 6, Traffic Signal Coordination Software ( Synchro 6 ), which employs methodology from the Highway Capacity Manual (HCM 2000) published by the Transportation Research Board National Research Council. Synchro 6 can analyze both signalized and unsignalized intersections in a road corridor or network, taking into account the spacing, interaction, queues, and operations between intersections. The signalized intersection analysis considers two separate measures of performance: The capacity of the intersection movements, which is based on a volume to capacity ratio; and The level of service, indicated by a letter, which is based on the control delay per vehicle for the various movements through the intersection and overall. The unsignalized intersection analysis considers two separate measures of performance: The capacity of the critical intersection movements, which is based on a volume to capacity ratio; and The level of service for the critical movements, indicated by a letter, which is based on the average control delay per vehicle for the various critical movements within the intersection.

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment 2. EXISTING CONDITIONS As previously noted, the 2009 estimated landfill waste intake is 180,000 tonnes, slightly higher than the projected 25-year average annual intake of 170,000 tonnes being assessed as part of this environmental assessment process. Thus, current conditions are representative of projected annual average waste receipts 2.1 Study Area Road Network The Clean Harbors is located in the southeast corner of the intersection of Petrolia Line at Telfer Road. Access to the facility is via Telfer Road. A summary of the study area road network is as follows: Highway 402 is a four-lane divided highway under jurisdiction of MTO. The posted speed limit is 100 km/h; however, in the westbound direction, the speed limit on Highway 402 is reduced to 80 km/h east of the Airport Road interchange with a further speed reduction to 70 km/h east of the Highway 40/Modeland Road interchange to account for the approaching international border and the potential for traffic queues on the mainline highway. Modeland Road/Highway 40 is a provincial highway with a posted speed limit of 80 km/h under the jurisdiction of MTO. It is a four lane divided highway from Highway 402 to London Line. South of London Line, the highway narrows to a two-lane undivided cross-section. Kimball Road is a two-lane undivided road with a rural cross-section and a posted speed limit of 90 km/h under the jurisdiction of the County of Lambton. There are approximately 1-metre gravel shoulders and drainage ditches on both sides of the road. Mandaumin Road is a two-lane undivided road with a rural cross-section and a posted speed limit of 90 km/h under the jurisdiction of the County of Lambton. The speed limit is reduced to 50 km/h through the residential community of Mandaumin. There are gravel shoulders and drainage ditches on both sides of the road. Plank Road is a two-lane undivided road with a rural cross-section and a posted speed limit of 60 km/h in the vicinity of Modeland Road and Kimball Road under the jurisdiction of the County of Lambton. Southeast of the intersection of Plank Road at Kimball Road/Churchill Line the speed limit increases to 90 km/h. There are gravel shoulders and drainage ditches on both sides of the road. Petrolia Line is a two-lane undivided road with a rural cross-section and a posted speed limit of 90 km/h under the jurisdiction of the County of Lambton. There are gravel shoulders and drainage ditches on both sides of the road. September 2009 6 itrans Project # 4411

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment Telfer Road is a two-lane municipal road under the jurisdiction of St. Clair Township. North of Petrolia Line, Telfer Road has a gravel surface with a posted speed limit of 80 km/h. A paved portion of Telfer Road extends from Petrolia Line to south of the Clean Harbors entrances. South of the Clean Harbors entrances, Telfer Road reverts back to a gravel surface. The road has a rural cross-section throughout and drainage ditches on both sides of the road. 2.2 Study Area Intersections The unsignalized study area intersections assessed are: Highway 402 Westbound exit ramp at Modeland Road Highway 402 Eastbound exit ramp at Highway 40 Highway 402 Westbound exit ramp at Mandaumin Road Highway 402 Eastbound exit ramp at Mandaumin Road Petrolia Line at Kimball Road Petrolia Line at Telfer Road Petrolia Line at Mandaumin Road Telfer Road at Clean Harbors site access driveway Mandaumin Road at London Line Mandaumin Road at Churchill Line The signalized study area intersections assessed are: Highway 40 at Plank Road Highway 40 at Confederation Street/Confederation Line Kimball Road/Churchill Line at Plank Road The study area road network and existing lane configurations at the above-noted study area intersections are illustrated in Exhibit 3. 2.3 Existing Traffic Volumes Turning movement counts for the weekday AM and PM peak periods at the study area intersections were obtained from MTO and Lambton County. For intersections where current turning movement count data was not available, weekday AM and PM peak period counts were completed by Pyramid Traffic on behalf of itrans. The traffic count dates and sources for the study area intersections are summarized in Table 1. September 2009 7 itrans Project # 4411

Based upon the review of the daily intake log, it was determined that a total of 39 Lambton landfill trucks entered the facility on April 6, 2009 and 30 Lambton landfill trucks exited the site. During the weekday AM peak hour, a total of 2 trucks, or 5 percent of the daily inbound Lambton landfill truck traffic entered the site and 1 truck, or 3 percent of the daily outbound Lambton landfill truck traffic exited the site. During the weekday PM peak hour, a total of 8 trucks or 21 percent of the daily inbound Lambton landfill truck traffic entered the site and 6 trucks or 20 percent of the daily outbound Lambton landfill truck traffic exited the site. For the purposes of this assessment, it has been assumed that Lambton landfill trucks arriving and departing the utilized the approved haul routes. Therefore, observed inbound and outbound Lambton landfill truck movements recorded at the intersection of Petrolia Line at Telfer Road have been tracked through the study area intersections based on the approved haul routes. The resulting existing site generated weekday AM and PM peak hour Lambton landfill truck traffic volumes are illustrated in Exhibit 4. September 2009 9 itrans Project # 4411

Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment 2.5 Existing Intersection Operations To develop the 2009 baseline traffic condition it was necessary to grow the traffic counts completed in previous years to the base year 2009. Through discussions with the County of Lambton, a simple growth rate of 0.5% per annum was applied to all individual movements at intersections to form the 2009 baseline traffic conditions for assessment. The resulting existing traffic volumes at the study area intersections are illustrated in Exhibit 5. Based on the traffic volumes identified in Exhibit 5 and existing signal timing plans obtained from MTO and Lambton County, the existing traffic conditions at the study area intersections are summarized in Table 2 for the unsignalized intersection operations and Table 3 for signalized intersection operations.

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment 3. 25-YEAR HORIZON TRAFFIC CONDITIONS 3.1 Future Background Traffic Growth In order to assess the 25-year horizon intersection operations, the background traffic growth that is anticipated on the study area road network must be calculated. This growth in traffic is representative of traffic-generating development over the next 25 years that can be reasonably expected although is not presently known. In discussions with Lambton County staff, it was agreed that a simple growth rate of 0.5% per annum was appropriate for a 25 year horizon. This equates to a 12.5% increase in traffic volumes at all study area intersections with the exception of traffic movements to/from Telfer Road (at Petrolia Line). For the purposes of this assessment, it has been assumed that all traffic on the south approach of Telfer Road is traffic and as such, will not increase over this time period. 3.2 Future Lambton Landfill Truck Traffic Given that the Lambton landfill is currently in operation and the current annual waste intake is representative of the forecasted ongoing annual intake of waste, there is not anticipated to be any additional Lambton landfill traffic on the study area intersections beyond that which has been observed during the 2009 turning movement counts. As such, no additional site traffic has been forecast for the 25-year horizon conditions. 3.3 25-year Horizon Intersection Operations The resulting 25-year horizon traffic volumes at the study area intersections are shown in Exhibit 6. The 25-year horizon traffic operations at the study area intersections were analyzed based on the traffic volumes illustrated in Exhibit 6 and with the existing road network as shown in Exhibit 3. The existing signal timings have been adjusted where necessary to optimize intersection operations at the study area intersections. The 25-year horizon traffic conditions at the study area intersections are summarized in Table 4 for unsignalized intersection operations and in Table 5 for signalized intersection operations. Level of Service definitions for both signalized and unsignalized intersection operations can be found in Appendix A, while detailed Synchro output reports are provided in Appendix C of this report.

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment 4. WASTE INTAKE SENSITIVITY ANALYSIS As previously noted, the 2009 estimated landfill waste intake is 180,000 tonnes, slightly higher than the projected 25-year average annual intake of 170,000 tonnes being assessed as part of this environmental assessment process. Thus, current conditions are representative of projected annual average waste receipts. Nevertheless, a sensitivity analysis has been completed to assess the impact of annual variations of waste intake to the landfill and to determine whether this increased Lambton landfill traffic could be accommodated on the existing road network over the next 25 years, should it occur. In order to assess the potential impacts on the study area intersections associated with increased activities to the landfill, it is necessary to establish a reasonable upper limit of intake that could potentially be accepted by the facility. Based upon a review of the historical landfill waste receipts at the facility during the 20-year period of 1987 to 2006, the average annual landfill waste receipt is approximately 170,000 (170,282) tonnes although there have been significant variations in the annual landfill waste receipts through this 20-year period. During a three-year period from 1998 to 2000, the landfill waste receipts of the site were significantly increased with 1999 being the peak year of annual intake with approximately 380,000 tonnes. For the purposes of assessing the transportation impacts associated with a high volume intake scenario, an annual intake of 380,000 tonnes has been utilized. Furthermore, utilizing historical waste receipts of the facility, a monthly intake adjustment and a daily intake adjustment was applied to the weekday AM and PM peak hour Lambton landfill truck traffic collected at the intersection of Petrolia Line at Telfer Road on Monday, April 6, 2009. The resulting peak hour site traffic can be considered a conservative projection based on the peak year, peak month, and peak day-of-week waste intake trends to determine a worst-case scenario of the potential impacts of Lambton landfill traffic on the study area intersections. The results of this assessment scenario are detailed herein. 4.1 High Volume Waste Intake Site Trip Distribution The high volume waste intake Lambton landfill truck traffic distribution has been developed using the existing directional movements observed at the intersection of Telfer Road at Petrolia Line. This location provided opportunity to isolate the Lambton landfill truck traffic from other truck traffic on the study area road network as it is reasonable to assume that the truck movements to and from the south approach of Telfer Road were associated with the. Furthermore, observations at this location were able to further categorize the truck traffic as being Lambton landfill truck traffic or incinerator truck traffic as the incinerator-related truck traffic use liquid container trucks. For the inbound daily Lambton landfill truck traffic distribution, it is evident that the majority of haulers respect Clean Harbors request that inbound loaded trucks utilize Highway 40 as 95 percent of all inbound trips are from the west. The outbound daily Lambton landfill truck traffic distribution, based on the 8-hour observed turning movement September 2009 20 itrans Project # 4411

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment counts at the intersection of Telfer Road at Petrolia Line, is 54 percent of outbound trips to the west and 46 percent of outbound trips to the east. 4.2 High Volume Site Traffic Projections Turning movement counts at the intersection of Petrolia Line at Telfer Road were undertaken on Monday April 6, 2009 to capture the Lambton landfill traffic to the. The Lambton landfill truck traffic was distinguishable from the incinerator truck traffic as incinerator-related trucks are liquid container trucks. For the purposes of this assessment, all non-liquid container trucks observed were considered to be associated with the landfill operations of the facility. Based on the annual landfill truck volumes between 1987 and 1992, and the annual waste intake of the landfill during this same period, an average waste per truck was established to be approximately 19 tonnes per truck. A review of the daily waste receipts for the facility between January 2007 and March 2009 calculates the average waste per truck to be 15.35 tonnes and the average waste per truck during the traffic data collection on April 6, 2009 was calculated to be 26.36 tonnes. Based on the data provided and through discussions with Clean Harbors, it was determined that the historical average of 19.06 tonnes per truck would be representative of the long-term operations for the landfill. The high volume annual waste intake of 380,000 tonnes is 211 percent more than the projected landfill waste receipts of 180,000 tonnes for 2009, and 224 percent more than the annual landfill waste receipts of 170,000 tonnes proposed for the next 25 years. For conservative purposes, an adjustment factor of 2.24 was applied to the April 6, 2009 peak hour Lambton landfill truck turning movements to and from Telfer Road to represent the increased traffic associated with the high volume waste intake. A review of the Lambton landfill daily truck volumes between January 2007 and March 2009 indicates that the landfill has two peak months of operation, those being April and October. A summary of the monthly variation of the truck volumes is summarized in Table 6. Since the field data collected for this assessment was obtained in April 2009, no adjustment factor needs to be applied to the represent peak month conditions.

An adjustment factor of 1.24 was applied to the Monday peak hour turning movement counts to and from Telfer Road to represent peak day of the week operations. To be conservative, it was also assumed that the peak hour employee traffic would increase proportionately to the peak hour Lambton landfill truck traffic.

The existing signal timings have been adjusted where necessary to optimize intersection operations. The high volume waste intake traffic conditions at the study area intersections are summarized in Table 8 and in Table 9 for signalized intersection operations.

Clean Harbors Canada, Inc. Proposed Lambton Landfill Expansion Environmental Assessment Terms of Reference Transportation Assessment 5. SUMMARY AND CONCLUSIONS Clean Harbors has initiated an Environmental Assessment (EA) process to examine the possibility of continuing the operations of the Lambton landfill for a further 25 years with an average annual landfill waste receipt of 170,000 tonnes per annum. The 121-hectare is owned and operated by Clean Harbors Canada, Inc. and is located at 4090 Telfer Road in Lambton County. The facility is bounded by Petrolia Line to the north, Telfer Road to the west and agricultural lands to the south and east. The projected traffic volumes and access arrangements will not vary between the two alternatives proposed for consideration in the Environmental Assessment. Therefore, this assessment can be considered to be common to both alternatives. Based on the assessment completed herein, 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. Furthermore, the existing study area road network and intersections have sufficient reserve capacity to accommodate the additional Lambton landfill truck volumes associated with the High Volume Waste Intake scenario, equivalent to an annual waste intake of 380,000 tonnes, should it occur.
