2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

Executive Summary The Glamorgan waste disposal site operates as a waste transfer station under the Ministry of the Environment, Conservation and Park Provisional Certificate of Approval No. A330401, most recently amended April 5, 2011. The Glamorgan landfilling operation was officially closed in July 2002, with final capping of the mound having occurred in 2006, and now operates as a transfer station.

The Glamorgan waste disposal site is on Lot 30, Concession V, in the geographic township of Glamorgan, in the Municipality of Highlands East, County of Haliburton, approximately 3.0 km east of the Hamlet of Gooderham, south of Highway 503, at 1070 McColls Road.

Groundwater elevations recorded in 2018 indicated that the overburden groundwater flow was to the south-southwest in the shallow overburden layer and to the south in the deep overburden, towards the Irondale River.

Based on the water quality results from 2018 there was a dilute leachate plume emanating from the waste mound towards the south. Due to site closure and natural attenuation, the leachate plume was weak and did not extend laterally much beyond the actual waste pile.

The 2018 water quality data confirmed that the surface water quality in the Irondale River downstream of the Glamorgan waste disposal site is similar to background surface water conditions and was not adversely impacted from the waste disposal site.

The site compliance was determined in 2018 by completing an assessment of the water quality at groundwater monitoring wells OW8, OW8B, OW9, and OW9B using the Provincial Water Quality Objectives and the Ministry of the Environment, Conservation and Park Guideline B-7 Reasonable Use Concept. Based on the assessment completed to date, the Glamorgan waste disposal site was interpreted to be in compliance with both the Reasonable Use Policy and the site-specific Trigger Mechanism.

It was estimated by the Municipality of Highlands East that 111.84 tonnes of blue box materials and waste electrical and electronic equipment were diverted from the site. In addition,

2.0 Methodology

This section provides a brief description of the methodology followed to complete the 2018 monitoring program.

The work program completed in 2018 was to maintain compliance with the Site PC of A and the Ministry. As such, the environmental monitoring work program was completed in accordance with the reports entitled Guidance Manual for Landfill Sites Receiving Municipal Waste (MOEE, 1993) and Monitoring and Reporting for Waste Disposal Sites, Groundwater and Surface Water, Technical Guidance Document (MOE, 2010).

Field tasks were completed following Cambium’s Standard Operating Procedures developed from recognized standard procedures such as those listed above and the Ministry document Guidance on Sampling and Analytical Methods for use at Contaminated Sites in Ontario (MOEE, 1996). A health and safety program was developed for Site specific conditions and all Cambium personnel working on the project were familiarized and required to follow the identified protocol.

All collected groundwater samples were stored in coolers with freezer packs and maintained less than 10C during transport to the SGS Environmental Analytical Laboratory in Lakefield, Ontario (SGS). SGS is accredited by the Canadian Association for Laboratory Accreditation Inc. (CALA), for specific environmental tests listed in the scope of accreditation approved by CALA.

2.1 Groundwater Monitoring Program

Groundwater sampling and monitoring was completed on-site on June 12, 2018, as outlined on Table 1. Static water levels and groundwater samples were collected by Cambium staff from the following monitoring wells in the established groundwater monitoring network (Figure 3).

 OW5  OW8  OW8B  OW9  OW9B  OW10

Cambium Inc. Page 3 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

The following monitoring wells were measured for static water levels only:

 OW1  OW2A  OW2B  OW3  OW4A

 OW4B  OW7A  OW7B  OW11

There were no deviations from the approved groundwater monitoring program as outlined in Table 1 in 2018.

The following tasks were completed as part of the monitoring program:

 Prior to sampling, water levels were measured at each monitoring well using an electronic water level tape.

 Each groundwater monitoring well to be sampled was purged of approximately three well bore volumes. Where wells were observed to go dry, only one well volume was purged. The volume of groundwater to be purged was calculated on-site during each monitoring event using the measured water level and the well diameter. Purge water was disposed of on-site, down-gradient of each respective monitor.

 Samples were collected using dedicated polyethylene tubing equipped with inertial-lift footvalves.

 Where required (i.e., groundwater for metals analysis), samples were field filtered.

 Field measurements were collected including: pH, conductivity, temperature, dissolved oxygen (DO), and oxygen reduction potential (ORP).

Groundwater elevations and UTM locations are presented in Table 2. The results of the 2018 monitoring program are discussed in Section 3.2.3 and 4.1 and analytical results are summarized in Table 3.

The location of each monitoring well is shown on Figure 3. The groundwater field data sheets are provided in Appendix B, the Certificates of Analysis received from SGS are in Appendix C, and photographs of the groundwater monitoring wells are in Appendix D.

Cambium Inc. Page 4 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

A blind duplicate groundwater sample was collected from monitoring well OW9B as part of the Quality Assurance/Quality Control (QA/QC) program. In addition to this sample, the laboratory completes an internal QA/QC. As this represents 10 percent of the samples taken, this program is considered sufficient. The results of the QA/QC program are presented in Section 4.1.

2.2 Surface Water Monitoring Program

On June 12 and November 7, 2018, surface water samples were collected by Cambium staff from surface water monitoring stations SP1 and SP2 (Figure 2). There were no deviations from the approved surface water monitoring program outlined in Table 1 in 2018.

The following tasks were completed as part of the monitoring program:

 Surface water samples were collected by immersing the sample container into the water body.

 Where sample bottles were prefilled with preservatives, a clean bottle was used to collect and decant the water directly into the sample bottle.

 Field measurements were collected including: pH, conductivity, temperature, DO, and ORP.

 Where possible, the following measurements were collected at each surface water location: depth, width, and flow velocity measurements.

The results of the surface water monitoring program are discussed in Section 4.2 and analytical results are summarized in Table 4.

The surface water field data sheets are provided in Appendix B, the laboratory Certificates of Analysis as received from SGS are in Appendix C, and photographs of the surface water monitoring stations are in Appendix D.

The following blind duplicate surface water samples were collected as part of the QA/QC program. In addition to these samples, the laboratory completes internal QA/QC. As this represents 10 percent of the samples taken, this program is considered sufficient. The results of the QA/QC program are presented in Section 4.2.

 November: SP1

2.3 Landfill Gas Monitoring Program

Currently, landfill gas is not actively managed at the Glamorgan waste disposal site. The large, open site area and isolated location from the public supports a passive landfill gas management process, which allows generated landfill gas to naturally disperse through the waste and naturally-permeable cover soil to the atmosphere. In addition, as described in the report entitled Site Development and Operations Report (Robinson, 1999), the sandy soil will adequately vent the waste mound from any gas generated.

2.4 Site Inspection and Operations Overview

Site operations were observed during the visits conducted by Cambium staff in June and November 2018. During these visits the following items were inspected on accessed areas of the Site and observations noted in the field file:

final cover integrity condition and layout of  litter control   access roads, access gates condition and layout of  status of monitoring  well security recycling bins

In January 2019, the Municipality provided additional 2018 site maintenance information. The results of the site inspections conducted are presented in Section 5.0.

3.0 Geological and Hydrogeological Context

3.1 Topography and Drainage

According to the report entitled 1994 Monitoring Report (CRA, 1995), the Site is in a bedrock rift valley adjacent to the flood plain of the Irondale River. A thick sequence (greater than 17 m) of silty sands and sandy silt underlie the Site. The depth to bedrock is undetermined. The relatively permeable soils at the Site permit rapid infiltration resulting in little or no surface ponding; however, in times of high runoff (i.e., spring and autumn) the water level of the Irondale River rises and water ponds in the low areas surrounding the Site indicating a hydraulic connection between the shallow unconfined aquifer and the Irondale River.

The Irondale River is in the Gull River watershed (2HF-05), which is in the Trent River and Lake Ontario drainage basins. This tertiary watershed spans from southern Algonquin Provincial Park and drains to Balsam Lake and the Trent-Severn Waterway. As documented by Parks Canada (2011), the Gull River watershed is an integral part of the Trent-Severn Waterway. The water levels of the lakes in the drainage basin are closely monitored in order to preserve the reservoir year-round. Lake levels generally swell during the spring thaw and late autumn, and settle back to normal by mid-June. The lowest water levels are in late winter. The watershed is used primarily for recreational uses, such as seasonal residents, whitewater kayaking, and fishing. No significant wetlands have been identified within 500 m of the Site.

The local topography generally slopes from north to south towards the Irondale River. The Irondale River, which flows in a northeast to southwest direction, is sampled upstream of the Site at surface water monitoring station SP1 (17T 708666 4976061) located at the bridge southeast of the Site. Surface water monitoring station SP2 (17T 7083245 4975881) is on the Irondale River approximately 480 m downstream from station SP1 and monitors potential landfill impacts on surface water quality downstream of the Site. Refer to Appendix D for photographs of the surface water monitoring stations and to Figure 2 for sampling locations.

Flow and discharge rates are not able to be accurately determined during the sample events due to the width of the channel; however, it is estimated that the flow of the river is greater than

Cambium Inc. Page 7 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

2 m³/s. There was no staining observed at the surface water monitoring locations that would be indicative of groundwater leachate discharge in 2018.

A review of the 2018 precipitation data in comparison to the average precipitation for Haliburton County (1981 to 2010; (Government of Canada, 2015)) indicated average precipitation was consistent with the climate normal. The months corresponding with the sampling events, June and November received 75% and 92% of the precipitation normally received, as outlined in Embedded Table 2. Notably, March was the only month that received significantly less than the historic normal, which was 53% of the precipitation observed. Refer to Appendix B for the June and November monthly precipitation data (Government of Canada, 2018).

Embedded Table 2 Historical and 2018 Precipitation Data Average Monthly Precipitation During 2018 Total Monthly Sampling Date Precipitation (mm) and Prior to Sampling Precipitation (mm) (1981-2010) (mm) June 12, 2018 81.2 61.0 Trace November 7, 2018 116.4 107.0 16.2

3.2 Hydrogeology

Based on the borehole logs and hydrogeologic cross-sections provided in Appendix E, the hydrogeology of the Site is summarized below and included in Table 6. Borehole logs for monitoring wells OW7, OW8, OW9, OW10, OW11, and OW12 are not available.

3.2.1 Overburden Aquifer

The Site is underlain by an unconfined overburden aquifer having an estimated total thickness greater than 17 m as indicated by the measured depth at monitoring well OW11. The overburden aquifer consists of glacial outwash sediments that vary from ‘silty sand’ to ‘silt with some sand’ to ‘well graded and poorly graded sands’. The aquifer is generally comprised of two distinguishable layers:

The “Shallow” Overburden Layer is comprised of:

Cambium Inc. Page 8 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

 upper well graded sand (monitoring well OW4B)

 lower silty sand (monitoring wells OW1, OW2B, OW3, OW5, OW7A, OW8B, and OW9B) overlying

The “Deeper” Overburden Layer is comprised of:

 silt with some sand (monitoring wells OW2A, OW4A, OW7B, OW8, OW9, OW10, OW11, and OW12)

These stratigraphic layers, illustrated on the cross sections in Appendix E, are believed to be interconnected. The uppermost ‘well graded sand’ layer is minimal and extends to depths of approximately 3.5 m from surface. The ‘silty sand’ portion of the shallow overburden layer comprises the majority of the identified overburden aquifer ranging from approximately 7.0 to 11.0 m in thickness. The deeper ‘silt with some sand’ layer is at least 6.0 m in thickness or greater. The deeper, ‘poorly graded sand’ was encountered at monitoring well OW4A; however, drilling ceased at that point and the extent of this layer is unknown.

Single well response tests (slug tests) were performed at monitoring wells OW1, OW2A, OW2B, OW4A, OW4B, and OW5 (CRA, 1994) and determined that the ‘silty sand’ (shallow) layer and the ‘silt with some sand’ (deep) layer of the aquifer yielded similar hydraulic conductivity values ranging from 1.01 x 10-3 to 1.48 x 10-3 cm/s. Monitoring well OW4A yielded a hydraulic conductivity of 2.75 x 10-3 cm/s, indicating a similarly permeable deposit, possibly indicative of the ‘poorly graded sands’ located at the bottom of this monitoring well. The uppermost ‘well-graded sand’ layer yielded a hydraulic conductivity of 1.18 x 10-2 cm/s, indicating the more permeable nature of this uppermost layer.

Historically, groundwater flow within the shallow overburden layer has been observed to be directed to the Irondale River which acts as a groundwater discharge zone. There has been a slight southwest component that is believed to discharge in a small tributary which traverses adjacent the western property boundary and discharges into the Irondale River. The primarily upward hydraulic gradient (discussed in Section 3.2.3) observed at monitoring wells OW4A/OW4B, OW8/OW8B, and OW9/OW9B, closest to the Irondale River, and at monitoring wells OW7A/OW7B adjacent the western property boundary and in vicinity of the small

Cambium Inc. Page 9 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019 tributary, verify that the low-lying areas adjacent the Irondale River act as local groundwater discharge zones, observed by ponded water during wet periods of the year. The Irondale River is the receiving surface water course for the discharged groundwater.

3.2.2 Bedrock Aquifer

According to the report entitled Landfill Impact Assessment Report (CRA, 1994), the bedrock in the area is described as carbonate metasedimentary rocks of the Grenville Province of the Canadian Shield. This includes marble, calc-silicate rocks, skarn, and tectonic breccias. Bedrock is located in excess of 17 m below surface. The bedrock contains a deeper aquifer that is utilized by a majority of the local water well users. As bedrock was not encountered during the installation of monitoring wells on the Site, no detailed information of this aquifer is available.

As the overburden aquifer is hydraulically connected to the Irondale River and the river is located directly down-gradient of the Site, any leachate impacts to the groundwater systems beneath the Site are expected to be confined to the upper aquifer discharging to the Irondale River.

3.2.3 Groundwater Flow Direction

In order to determine the groundwater elevation, water table gradients, and groundwater flow direction, water level measurements were collected on June 12, 2018. A summary of the groundwater elevation data is presented in Table 2 and groundwater elevations are shown on Figure 4. Water levels recorded in June were typically lower than what has been observed in recent years. This was attributed to a drier than normal May and June prior to the sampling event. Nonetheless, the water level were observed to be within their historic ranges in 2018.

Historically, the direction of groundwater flow was interpreted to be towards the south and southwest within the shallow overburden layer and interpreted to be towards the south within the deeper overburden layer. Figure 5 and Figure 6 show the shallow and the deep overburden layer groundwater configurations, respectively, as generated from the 2018 water elevation data. In the shallow overburden, the groundwater flow was calculated to be towards

Cambium Inc. Page 10 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019 the south-southwest at an average hydraulic gradient of 0.003 m/m. In the deep aquifer, the groundwater flow was calculated to be towards the south at an average hydraulic gradient of 0.002 m/m.

3.2.3.1 Vertical Gradients

Vertical hydraulic gradients were calculated at the multi-level monitoring wells. The water elevation data from June 2018 indicated an upward hydraulic gradient existed between the deeper overburden layer and the shallow overburden layer at monitors OW2A/OW2B, OW7A/OW7B, and OW8/OW8B. A downward vertical gradient was observed at monitors OW4A/OW4B and OW9A/OW9B. Vertical gradients are summarized in Table 7.

Where downward gradients were observed, these were attributed to the area temporarily acting as a recharge versus a discharge zone. This typically occurs when the water levels are lower and/or ponded water is not observed in the area adjacent the Irondale River (i.e., summer or early autumn).

The primarily upward vertical gradients observed confirm the hydrogeological characteristics of the Site. It has historically been interpreted any impacted groundwater at the Site would be restricted vertically to the shallow overburden aquifer and travel south from the waste mound to either the unnamed tributary or the Irondale River, where it discharges to the surface. Regardless of the downward gradients observed in 2018, it was inferred the Irondale River was still the ultimate receiver of impacted groundwater at the Site.

Cambium Inc. Page 11 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

3.2.4 Groundwater Flux and Velocity

Groundwater flux, or specific discharge, q, is the discharge of groundwater per unit of time and is calculated from Darcy’s equation. As the groundwater flux has the dimensions of a velocity, it is sometimes known as the Darcy velocity or Darcy Flux (Freeze & Cherry, 1979). The Darcy velocity is calculated from the following equation:

푞 = 퐾푖

Where: q= Groundwater flux (units of length per time) K= Horizontal hydraulic conductivity (units of length per time) i= Horizontal hydraulic gradient in direction of vs (dimensionless)

Using the average horizontal hydraulic gradient determined for the shallow and deep overburden (Section 3.2.3) and the hydraulic conductivities determined historically (Section 3.2.1), the corresponding Darcy velocity within the overburden units was calculated. As noted in Section 3.2.1, both the shallow and deep overburden units exhibited similar hydraulic conductivities, with only the shallow well graded sands exhibiting a slightly faster conductivity. Without considering the spatial variations in calculated conductivities, the Darcy velocities were determined to be between 3.5 x10-7 and 3.0 x 10-8 m/s, with an average velocity of 1.1 x 10-7 m/s.

The average linear groundwater velocity or seepage velocity can be calculated for a water bearing unit or aquifer using the horizontal hydraulic gradient, the hydraulic conductivity, and the porosity of the unit using the following equation:

퐾푖 푣̅ = 푛

Where: 푣̅= average linear groundwater velocity in units of length per time n = dimensionless formation porosity (usually sourced from literature) K = horizontal hydraulic conductivity in units of length per time i = dimension horizontal hydraulic gradient

Cambium Inc. Page 12 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

For unconsolidated deposits such as silts and sands, typical porosity values can range from 25 to 50 percent (Freeze & Cherry, 1979). Using the hydraulic conductivities determined for the overburden, the hydraulic gradients calculated in 2018, and an assumed porosity of 30 percent, the linear groundwater velocity for the overburden unit at the Site was estimated to be between 3 and 37 m/yr and an estimated average of 11 m/yr.

3.3 Groundwater/Surface Water Interaction

The overall conceptual model for the Site indicates that the leachate generated below the waste mound is restricted vertically to the overburden materials. As the leachate plume moves south of the waste footprint, the impacted waters discharge to the large area of peat soils in the low lying wet area north of the Irondale River. As there are no down-gradient water well users within 500 m of the Site and the groundwater is observed to discharge to surface at least part of the year, the primary potential receiver of impacted waters from the Site is the low lying wet area north of the Irondale River and the Irondale River itself.

Based on the hydrogeological conceptual model for the Site, the water quality at the monitors located in the peat area (i.e., OW8, OW8B, OW9, and OW9B) should be compared to the Provincial Water Quality Objectives (PWQO; (MOEE, July 1994)). This will aid in predicting any potential adverse impacts to the surface water down-gradient of the Site, as a result of leachate impacted groundwater discharging to surface. Refer to Section 4.3 for this discussion and assessment and to Table 5 for the analytical data.

4.0 Results and Discussion

Water quality results from the monitoring program are used to assess the existence, extent, and magnitude of impacts to the surface water and groundwater environments related to waste disposal site activities. The groundwater from the Site is interpreted to discharge to the low- lying areas north of the Irondale River; therefore, the groundwater nearest the Irondale River and the surface water systems should be monitored closely. To ensure appropriate responses exist to address any potential degradation in surface water or groundwater quality beyond an acceptable concentration, Site-specific trigger values and contingency plans have been developed for the Site to be used in the assessment of impacts.

This section presents the results of the 2018 monitoring program completed at the Site as compared to the historic results and discusses observed trends in the groundwater and surface water quality.

4.1 Groundwater Quality

The groundwater chemistry obtained from the analysis of groundwater samples collected from the monitoring wells at the Site from 2010 to 2018 is presented in Table 3. Historical groundwater quality data (2002 to 2016 for all sampled locations) are included digitally with the report package (SGS, 2006), (Cambium, 2017).

The groundwater quality has been compared with historic results and background water quality data. Compliance of the Site is evaluated using the Ministry Guideline B-7, Reasonable Use Concept (MOEE, 1994); refer to Section 4.1.5. Additional discussion related to groundwater/surface water interaction and compliance with the PWQO is included in 4.3.

Results from the analyses completed on the blind duplicate groundwater samples obtained from monitoring well OW9B in June as part of the QA/QC program were evaluated. Parameter concentrations were considered to be significantly different if the relative percent difference (RPD) between the duplicate and the original samples was greater than 30RPD when both analytical results were greater than five times the reported detection limit (RDL).

Cambium Inc. Page 14 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

In 2018, the results for the duplicate groundwater sample were similar to the parent sample collected. This included a review of the parent/duplicate samples with only one measurable concentration. If the measurable concentration was close to the detection limit, the sample results were considered valid and the measurable concentration was accepted. Evaluation of these parent/duplicate samples did not identify significant data quality issues.

Overall, the groundwater quality was interpreted with confidence and was considered suitable for its intended use, which was to identify changes in water quality and analyzed parameters present at concentrations that did not meet the compliance criteria.

4.1.1 Background Monitors

Monitoring well OW1 is up-gradient of the waste mound, samples the shallow overburden layer, and has historically been considered to be representative of background water quality for the Site. Most parameter concentrations at this location have been observed to be low, with the exception of manganese and dissolved organic carbon (DOC). Due to the location of this monitor, elevated concentrations at this location have been interpreted to be naturally occurring or attributed to non-waste related sources. Caution is used when assessing these parameters in the down-gradient monitoring wells.

This monitor is only sampled once every three years; the next sampling event at this monitor will occur in 2019.

4.1.2 Leachate Characteristics

Monitoring well OW3 is approximately 35 m immediately down-gradient of the waste mound in the underlying silty sand (shallow) layer of the overburden aquifer. Historically, there was a monitoring well located in the waste pile; monitoring well OW6. This well was damaged and decommissioned; therefore, monitoring well OW3 was established as the well most characteristic of leachate quality.

Based on the historical observations at monitors OW3 and OW6, in conjunction with the background water quality concentrations for the Site, leachate indicator parameters (LIPs) were identified for the Site and are outlined in Embedded Table 3.

Cambium Inc. Page 15 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

Embedded Table 3 Leachate Indicator Parameters total dissolved chemical oxygen boron sulphate hardness solids (TDS) demand (COD) DOC barium calcium total phosphorus potassium

These LIPs are used for the groundwater and surface water compliance assessments to ensure that the waste disposal site is not adversely impacting the Irondale River, the down-gradient receiver of the Site.

Monitoring well OW3 was removed from the monitoring program in 2016, with the exception of volatile organic compound (VOC) sampling to be conducted every five years, next in 2021 (Table 1). The historical water quality will continue to assess the down-gradient impacts at the Site. A review of the water quality from 2002 to 2016 indicated a general decrease in the LIP concentrations, as expected since the Site has been closed since 2002.

4.1.3 Western Cross-Gradient Monitors

Monitoring wells OW7A, OW7B, OW10, and OW11 are adjacent the western property boundary, cross-gradient of the waste mound; only monitoring well OW10 which samples the deep overburden layer remains in the monitoring program.

Groundwater monitoring well OW10 is approximately 120 m west of the edge of the waste mound. In 2018, elevated LIP concentrations for TDS, sulphate, hardness, barium, and calcium remained stable. A decreasing trend was evident for potassium concentrations. The impact observed at this location is at least in part related to the non-waste related source that historically was observed to impact monitors OW11 and OW7B (Cambium, 2017).

There is a Municipal works yard located northeast of the Site (Figure 2). Previous annual reports (CRA, 1995) identified a water well at the works yard up-gradient of the Site that supplies water for equipment washing. The water quality in the well was reported to be impacted by elevated concentrations of many parameters compared to the background water quality at the Site; therefore, this may be an indicator of an alternative up-gradient non-waste related source for the noted impacts at cross-gradient monitoring well OW10. The alternative source is likely impacting the deep monitoring wells only, as the water quality at monitoring

Cambium Inc. Page 16 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019 well OW1 samples the shallow overburden (un-impacted by the Site, located between the works yard and wells OW11 and OW7B) and does not reflect the elevated parameter concentrations observed at monitor OW10.

4.1.4 Southern Down-gradient Monitors

Shallow monitors OW4B, OW5, OW8B, and OW9B and deep monitors OW4A, OW8, and OW9 are down-gradient of the waste mound (Figure 3) and monitor potential impacts to water quality down-gradient of the Site. Monitors OW4A and OW4B were removed from the analytical program in 2016 (Cambium, 2017).

4.1.4.1 Shallow Overburden Monitoring Wells

Monitoring well OW5 is approximately 130 m southwest of the waste mound and samples the shallow overburden layer. Water quality at this location is characterized by moderately low concentrations of most parameters; typically similar or often less than concentrations observed in the background water quality.

Monitoring well OW8B samples the shallow overburden aquifer and is the nearest monitor to the southern property boundary, approximately 25 m north of the Irondale River (Figure 5). The monitor is installed in an area observed to be wet part of the year (Appendix E). Water quality data at monitoring well OW8B has been observed to have elevated concentrations of the following LIPs: TDS, sulphate, hardness, barium, calcium, and potassium. These elevated parameter concentrations have indicated impact at this location from the waste disposal site. Monitor OW8B has also been observed to have elevated concentrations of iron, manganese, and DOC attributed to the wetland-type environment and saturated soils (Bendell-Young, 2003).

Monitoring well OW9B samples the shallow overburden aquifer and is approximately 120 m south of monitoring well OW5, adjacent the southwest property corner, and approximately 55 m north of the Irondale River. Water quality at OW9B is characterized by moderately low concentrations of most parameters, typically similar to or often less than concentrations observed in the background water. Nonetheless, monitor OW9B has been observed to have

Cambium Inc. Page 17 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019 some elevated parameter concentrations such as iron, manganese, and DOC, attributed to the wetland-type environment, similar to monitor OW8B. This monitor was also observed to be wet from surface and is located in an area of peat.

In 2018, the water quality data at the shallow down-gradient locations were generally observed to be consistent with historical results.

4.1.4.2 Deep Overburden Monitoring Wells

Monitoring well OW8 samples the deep layer of the overburden aquifer and is adjacent monitor OW8B, near the southern property boundary. The LIP concentrations at this location have generally been observed to be slightly greater than background water quality parameter concentrations. Monitoring wells OW8 and OW8B are located adjacent the Irondale River, in an area observed to be wet part of the year, creating a wetland-type environment. Elevated concentrations of parameters such as alkalinity, iron, manganese, magnesium, calcium, and DOC are often observed in these types of environments; therefore, may attribute to some of the elevated concentrations observed at this location (Bendell-Young, 2003).

Monitoring well OW9 samples the deep portion of the overburden aquifer and is adjacent monitor OW9B, approximately 120 m south of monitoring well OW5. This monitor is adjacent the southwest property boundary and approximately 55 m north of the Irondale River. Historically, water quality observed at this location has been observed to have elevated concentrations of many LIPs when compared to the background groundwater quality at the Site. Due to the groundwater flow direction and the location of the waste mound in reference to this monitor, an assessment was completed of the water quality at monitor OW9 and compared to water quality at monitor OW11 cross-gradient of the waste mound interpreted to be impacted by a non-waste related source and the leachate monitor OW3 (Cambium, 2014). This assessment revealed that the water quality signature at monitor OW9 more closely resembled that of monitor OW11 than that of the leachate impacted well on-site (e.g., OW3). Based on this assessment, although increasing parameter concentrations have been observed at this location historically, the impact was not attributed to increased impact from the Site (Cambium, 2014).

Cambium Inc. Page 18 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

Water quality in 2018 was observed to be consistent with historical results at all down-gradient deep monitors, with stable or decreasing trends observed for most elevated LIP concentrations.

4.1.5 RUC Compliance Assessment

To ensure appropriate recognition and response to potential degradation in groundwater quality beyond an acceptable concentration, Site specific triggers and contingency plans have been developed for the Site. These are based on the Ministry’s Reasonable Use Concept (RUC) values for groundwater (MOEE, 1994). The Ministry’s Reasonable Use Policy states that, in accordance with the appropriate criteria for particular uses, a change in quality of the groundwater on an adjacent property will be accepted only as follows:

The quality cannot be degraded by an amount in excess of 50% of the difference between background and the Ontario Drinking Water Standards (ODWQS) for non- health related parameters and in excess of 25% of the difference between background and the ODWQS for health related parameters. Background is considered to be the quality of the groundwater prior to any man made contamination.

Ministry Procedure B-7-1.

The maximum concentration of a particular contaminant that is considered acceptable in the groundwater beneath an adjacent property is calculated in accordance with the following relationship:

퐶푚 = 퐶푏 + 푥 ∙ (퐶푟 − 퐶푏)

Where: Cm = maximum concentration accepted

Cb = background concentration

Cr = Maximum concentration permitted in accordance with the Ontario Drinking Water Standards x = a constant that reduces the contamination to a level that is considered by the Ministry to have a negligible effect on water use. i.e. 0.5 for non-health related parameters 0.25 for health related parameters.

Cambium Inc. Page 19 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

In 2018, the RUC values were calculated for all LIPs (Embedded Table 3) using the median value of the background concentration (Cb) from a minimum of the previous five sampling events. The maximum allowable concentration (Cm) of any particular parameter may be calculated using the background concentration of that parameter from a monitor up-gradient of the Site, the designated ODWQS value for that parameter, and a constant that reflects whether the parameter is health or aesthetic-related as defined by the ODWQS. Where background concentrations were less than the RDL, the RDL was used as the background value. The calculated Cm values for the site were set as the RUC values. Where a background value exceeded the ODWQS value, the Cb value was set as the RUC value.

In 2018, the RUC values were calculated for the Site using background water quality data from monitoring well OW1, between May 2002 and May 2016, for the LIPs included in Embedded Table 3. The down-gradient monitoring wells included in the approved monitoring program (OW5, OW8/OW8B, OW9/OW9B, and OW10), located in closest proximity to the property/river’s edge boundary, were used for the RUC evaluation as presented in Table 3. The RUC exceedances observed in 2018 are summarized in Embedded Table 4.

Embedded Table 4 RUC Exceedances, June 2018 Monitoring Parameter (s) Well Shallow OW5 none observed OW8B DOC OW9B none observed Deep OW8 TDS OW9 TDS OW10 none observed

As prescribed in the report entitled Site Development and Operations Report (Robinson, 1999), the groundwater trigger mechanism for the Site is based on the RUC.

Cambium Inc. Page 20 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

The trigger mechanism is as follows:

If continued exceedances of the RUC persist at the furthest down-gradient monitor over a period of three consecutive monitoring events, the contingency plan would be implemented. Immediate steps would include increased monitoring frequency of key tracer parameters, or the installation of additional monitoring station. Subsequent to this, a more detailed assessment to define the problem would be completed, and then corrective measures implemented.

Typical corrective measures would be the acquisition of an attenuation zone south of the existing landfill area. Current flow paths have determined that the direction of groundwater flow is south from the Site, and consequently, there is no anticipated impact in other directions. Should hydraulic gradients change additional monitors may be required to assess potential off-site migration. Remediation measures would be the acquisition of attenuation properties in those directions.

Based on the above, the trigger was initiated at monitor OW8B for DOC in 2018. Concentrations for this parameter have been graphed; refer to Figure 7.

As documented in the article entitled Peatland Interstitial Water Chemistry in Relation to that of Surface Pools along a Peatland Mineral Gradient (Bendell-Young, 2003), which discusses the water chemistry associated with peatlands in the Muskoka-Haliburton region, concentrations of DOC, iron, and manganese were observed to be as great as 16.8 mg/L, 2.17 mg/L and 0.09 mg/L, respectively. The average concentrations of DOC, iron, and manganese observed since installation of monitor OW8B in early 2015 are 7.4 mg/L, 1.5 mg/L, and 0.41 mg/L, respectively. As such, the elevated concentrations of these parameters, and DOC at monitor OW8B in particular, have not been attributed to the Site. It is further noted, that the concentrations of DOC at monitor OW8B were observed to be within concentration ranges observed at background monitor OW1, further indicating adverse impact from the Site is unlikely; refer to Figure 7.

Based on this assessment, no actions were warranted and the Site was interpreted to be in compliance with the Ministry’s Reasonable Use policy in 2018.

Cambium Inc. Page 21 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

4.2 Surface Water Quality

Surface water samples were collected from surface water monitoring stations SP1 and SP2 in June and November 2018. The water quality data from 2010 to 2018 is presented in Table 4. Historical water quality from 2005 to 2010 is included digitally with this report package. The surface water data have been compared to historical background concentrations and the PWQO (MOEE, July 1994).

Results from the analyses completed on the blind duplicate surface water samples obtained from sampling stations SP2 and SP1 in June and November, respectively, as part of the 2018 QA/QC program were evaluated. Parameter concentrations were considered to be significantly different if the RPD between the duplicate and the original samples was greater than 30RPD when both analytical results were greater than five times the RDL.

In 2018, the data for duplicate surface water samples were similar to the parent samples collected for all parameters. This included a review of the parent/duplicate samples with only one measurable concentration. If the measurable concentration was close to the detection limit, the sample results were considered valid and the measurable concentration was accepted. Evaluation of these parent/duplicate samples did not identify significant data quality issues.

Overall, the surface water quality was interpreted with confidence and was considered suitable for its intended use, which was to identify changes in water quality and analyzed parameters present at concentrations that did not meet the compliance criteria.

4.2.1 Background Quality

In order to assess the potential impact of the Site on the Irondale River, water quality data from the downstream station were compared to that from the upstream station. Historically, the surface water quality at station SP1 has been considered representative of background conditions as it is located upstream of the waste disposal site (Figure 2). The water quality at this location has been characterized as having: low concentrations of total suspended solids

Cambium Inc. Page 22 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

(TSS), DOC, COD, sulphate, barium, boron, calcium, and potassium, and slightly elevated concentrations of hardness and total phosphorus.

Generally, the water quality data observed in 2018 was consistent with historical results including the exceedance of the PWQO criteria for total phenols in June and November.

4.2.2 Down-gradient Surface Water Quality

Historically, no impact has been observed at downstream location SP2; this remained the case in 2018. Similar to the upstream monitoring station SP1, total phenols exceeded the PWQO criteria in June and November 2018.

4.3 Groundwater/Surface Water Interaction

Since 2008, a groundwater monitoring based trigger mechanism has been used at the Site (Cambium, 2014). The shallow aquifer at the Site discharges groundwater to the Irondale River; therefore, the down-gradient monitoring wells OW8, OW8B, OW9, and OW9B located adjacent the Irondale River are used for the compliance assessment. These wells are assessed using Guideline B-7 (as outlined in Section 4.1.5), the PWQO, and the LIPs outlined in Embedded Table 3.

4.3.1 Trigger Mechanism

A three tier system is employed to ensure the Irondale River is not adversely impacted by the waste disposal site. The three tier trigger mechanism consists of ‘Alert’, ‘Confirmation’, and ‘Compliance’ level monitoring tiers. These three tiers are defined as follows:

Tier I: ‘Alert’ The ‘Alert’ tier considers the list of LIP (Embedded Table 3) in comparison to the PWQO and Guideline B-7. If a parameter concentration exceeds a Tier I trigger value (Guideline B-7 RUC criteria and/or PWQO criteria) on three consecutive sampling events or significantly exceeds the PWQO at any one monitoring event, then the Tier II trigger is initiated within 30 days of receipt of analytical results.

Cambium Inc. Page 23 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

Tier II: ‘Confirmation” The ‘Confirmation’ tier includes the review of all available data and the evaluation of whether a trigger is partly or wholly explained by other factors. Contingent to this review, Tier II includes an increased sampling frequency and/or an increased parameter suite. This is completed to determine whether or not leachate from the waste disposal site is having an adverse impact on surface water quality, or if the elevated concentrations are occurring due to a non-related waste disposal site source(s). Upon this review, an evaluation of subsequent analytical results and discussion with concerned parties must occur.

The first step in Tier II will be achieved by considering trends in trigger parameter concentrations at the trigger locations in the context of: trigger parameter concentrations at non-trigger locations (i.e. up-gradient surface water monitoring station SP1) and non-trigger leachate indicator parameter concentrations at trigger and non-trigger locations. If this review confirms concentrations are most likely related to an increasing trend and discernible impact at the trigger location, the Ministry will be notified and collection and analysis of samples would be required on a monthly basis for a period of three months from both the background water quality monitoring well (OW1), the leachate monitoring well (OW3), and the four trigger mechanism monitoring locations (monitoring wells OW8, OW8B, OW9, and OW9B). This increased sampling should also include the two surface water monitoring locations to monitor the direct impact on the Irondale River.

If the exceedance is confirmed after Tier II monitoring, discussions will be held between the Municipality, the Municipality’s consultant, and the Ministry to determine whether the implementation of remedial measures are warranted. The scheduling of these discussions will occur within six months from the activation of the Tier II trigger. The discussions will define the optimum course of action and review the remedial measure alternatives available to the Municipality at that time.

If the Ministry confirms that the Tier II monitoring indicates an unacceptable threat to the surface water regime, then the remedial measures identified and agreed to during the above noted discussions will be implemented in concurrence with the Tier III Compliance

Cambium Inc. Page 24 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019 performance monitoring program within a maximum of 30 days of contingency plan implementation.

Tier III: ‘Compliance’ The ‘Compliance’ tier is to confirm if the implementation of the remedial measures is having a positive effect on the adversely impacted groundwater quality. The detailed scope of Tier III will be established following the definition of the proposed remedial measures.

Monitoring wells OW8, OW8B, OW9, and OW9B are used as the trigger locations. The water quality data obtained from these locations are used in the trigger assessment completed at each sampling event on an annual basis. The trigger parameters to be used are outlined in Embedded Table 3 and the calculated trigger values are summarized in Table 5.

Contingency Plan In the event that the Irondale River is adversely impacted by leachate from the waste disposal site, the closed waste mound will be covered with additional low permeable cover. In the event that the trigger mechanism proceeds to Tier II, then this option will be reviewed during discussions with the Municipality, the Municipality’s consultants, and the Ministry, as part of Tier II compliance.

4.3.2 Trigger Compliance Assessment

A review of the 2018 groundwater quality with respect to trigger parameters was completed. Table 5 provides a summary of the trigger mechanism water quality data. The exceedances observed for three consecutive events in 2018 for the Site LIPs are summarized in Embedded Table 5.

Embedded Table 5 Trigger Exceedances Monitor Parameter OW8 none observed OW8B DOC OW9 none observed OW9B total phosphorus

Cambium Inc. Page 25 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

Based on the above, the Tier II was initiated due to continued exceedances of the RUC criteria at monitor OW8B and the PWQO at monitoring well OW9B. As discussed in Section 4.1.5, elevated concentrations of DOC observed at monitor OW8B were not attributed to Site impacts and were considered to be reflective of the surrounding peatland environment.

Total phosphorus exceeded the trigger value on three consecutive occasions; however, the concentrations observed were within the range observed in the background water quality historically (OW1). This, and consideration that no other LIPs were observed to be elevated at this monitor and no impacts have occurred at the nearest surface water monitoring station SP2, the Site was considered in compliance with the trigger mechanism in 2018.

Based on the assessments outlined in Sections 4.2 and 4.3, the Irondale River continues to be un-impacted by the Site.

4.4 Adequacy of Monitoring Program

The monitoring program continues to effectively characterize site conditions, groundwater and surface water conditions, and includes data that relates to upstream/background and downstream receiving water conditions. At the Site, in whole or in part:

 All monitoring wells are confirmed to be in good condition and secure.

 All fieldwork for groundwater investigations was done in accordance with the standard operating procedures as established/outlined per the standard operating procedures (including internal/external QA/QC).

 All field work for the surface water investigations was done in accordance with standard operating procedures including internal/external QA/QC requirements.

 All groundwater and surface water sampling for the monitoring period was successfully completed in accordance with the PC of A.

 The Site has an adequate buffer, contaminant attenuation zone (CAZ), and contingency plan in place.

Cambium Inc. Page 26 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

 Design and operational measures, including size and configuration of any CAZ are adequate to prevent potential human health impacts and impairments of the environment.

 The Site meets compliance and assessment criteria.

Cambium Inc. Page 27 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

5.0 Site Operations

The Site operates under a PC of A No. A330401, amended April 5, 2011. The waste disposal site opened in 1969 and was officially closed to landfilling in July 2001. At the time of closure a transfer station was established at the Site; details of the transfer station operation were included in the document entitled Glamorgan Landfill, Revised Closure Plan (CCTA, 2003).

This section presents a summary of the 2018 operations at the Site.

5.1 Site Access and Security

The Site is accessed from 1070 McColls Road. A lockable gate controls vehicular access to the Site (Figure 3). Topography and dense vegetation control access to the remainder of the Site. Signage is posted at the gate, which lists the Site PC of A number, tipping fees, emergency contacts, acceptable wastes, hours of operation, and directions to donation centres for materials that remain in good condition. The entrance sign was replaced in November 2018 as it was in poor condition.

Following a Ministry Site inspection in 2017, the Municipality installed a lock on the gate dividing the transfer station and the closed waste disposal area. Furthermore, “No Trespassing” signs were installed at the entrance and along the northwest border of the Site (Cambium, 2018).

The hours of operation for the Site are:

Winter (Commencing the Saturday following Thanksgiving) Monday, Wednesday, Saturday & Sunday ...... 10:00 AM to 4:30 PM (Statutory) Holiday Mondays ...... 10:00 AM to 4:30 PM Summer (Commencing the last Saturday prior to Victoria Day) Monday, Wednesday, Saturday & Sunday ...... 10:00 AM to 6:00 PM (Statutory) Holiday Mondays ...... 10:00 AM to 6:00 PM

The Site is closed on January 1, December 25, and 26.

Cambium Inc. Page 28 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

In 2018, all waste disposal and transfer operations were conducted under the supervision and direction of the site attendant, employed by the Municipality. The site attendant was responsible for ensuring that the safe and orderly operation and maintenance of the Site complied with the requirements of the PC of A and the Environmental Protection Act (EPA) and its Regulations as administered by the Ministry. The site attendant’s responsibilities included, but were not limited to the following:

 controlling admission of authorized vehicles with acceptable wastes

 ensuring proper daily litter control

 controlling collection and haulage of materials by a licensed hauler

 maintaining a daily record of all operations which are available for inspection by the Ministry

5.2 Training

The Municipality provided in-house training for regular staff in December 2018. Training included information updates on general landfill operations procedures, ECA requirements (i.e., acceptable and non-acceptable materials, material tracking), and health and safety policies (i.e. nuisance bear). A brief test was completed by all staff who attended training and certificates of completion were issued for each individual.

5.3 Drainage

In times of high runoff (i.e., spring and autumn) the water level of the Irondale River rises and water ponds in the low areas surrounding the waste mound indicating a hydraulic connection between the shallow unconfined aquifer and the Irondale River. During visits by Cambium in 2018 no flooding or ponding was observed.

The waste mound was observed to be well vegetated with no signs of erosion noted by Cambium staff in 2018. In addition, the transfer station was observed to be well drained with no ponded areas or signs of depressions which could collect water during precipitation events.

Cambium Inc. Page 29 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

5.4 Roads

The Site access road was observed to be of an adequate width to provide good traffic flow for regular Site users, maintenance equipment and snow removal equipment. During Site visits by Cambium in 2018, the road was in good condition and no erosion or surface drainage ponding was observed.

5.5 Aesthetics

As noted by Cambium, the Site was observed to be in excellent condition; no evidence of blown litter was observed during any of the site visits in 2018.

5.6 Complaints and Incidents

Municipal records indicated that no complaints regarding site operations were received in 2018. Furthermore, the Municipality reported that there were no incidents at the Site in 2018.

5.7 Monitoring Well Security

As part of the 2018 groundwater monitoring program, each monitoring well listed in Table 1 was inspected for compliance with Ontario Regulation (O. Reg.) 903 and Section 39 Condition B of the Site PC of A (Appendix A). The following work was completed in 2018:

 The stick-up on monitoring well MW9B was shortened allowing the monitor to be properly locked.

The following work should be completed in 2019:

 The stick-up on monitoring well OW7A should be shortened to allow the monitor to be properly secured and locked.

Refer to Appendix D for photographs of the wells.

5.8 Materials Summary

The following waste types are accepted at the Site; refer to Figure 3 for the collection locations of each material.

 Household Waste  Blue Box Recyclables  Scrap Metal  Tires

 Waste Electrical and  CFC Appliances  Leaf and Yard  Automotive Electronic Equipment Waste Materials (WEEE)

Waste management information pamphlets have been prepared by the Municipality and are available to all rate payers at the Municipal offices and distributed at the waste disposal site. The information pamphlet provides an update to the waste management system in the Municipality, the status of each waste disposal site in the Municipality, and contains details regarding location, hours of operation, and types of waste accepted, including recyclable materials.

In 2017, the Site received new waste collection bins (Cambium, 2018). In the summer of 2018, two new cement pads were poured under the recycling and waste bins creating easier access for the waste haulers.

5.8.1 Site Usage

Site usage, as documented by the Municipality, is summarized in Embedded Table 6. Waste is collected in bins on-site and then transferred to the Municipality’s Bicroft waste disposal site located near Cardiff for disposal.

Embedded Table 6 Summary of Site Usage 2018 2017 2016 Vehicles – Private 21,161 20,891 21,663 Bags of Garbage1 64,303 56,671 47,243 Notes: 1. 46 bins (1,400 m³) were reported by the Township to be transferred to the Bicroft waste disposal site.

Cambium Inc. Page 31 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

Using the number of garbage bags, it is possible to determine the tonnage of residential waste deposited at the Site. Assuming each bag weighs 14 kg, 900 tonnes of residential waste was disposed of at the Site in 2018.

5.8.2 Site Diversion

Embedded Table 7 provides a summary of the materials diverted from the Glamorgan waste disposal site in 2018, as provided by the Municipality. The 111.84 tonnes of materials in 2018 was significantly greater than the five year average diversion weight of 92 tonnes.

In addition to the above, scrap metal is collected and removed from the Site. The amount of scrap metal transferred from the Glamorgan and Monmouth sites in 2018 was 94 tonnes.

5.8.3 Municipal Wide Diversion

The Municipality has entered into an agreement with the Raw Materials Company to provide battery recycling to the residents of the Municipality. There are centres provided at the Municipal offices and at all landfill sites. In total, 34 – 20 L pails of batteries were recycled in 2018 from the Municipality.

In addition to the above, the Municipality estimates that a total of 1,400 backyard compost units have been purchased by residents since 2003. There was no updated total for backyard compost units purchased for 2018. Assuming a diversion rate of 100 kg per unit per year

Cambium Inc. Page 32 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

(RPRA, 2018), an additional total of 140 tonnes of organic materials have potentially been diverted from Municipal landfills in 2018 through backyard composting participation.

Due to a high volume of seasonal residents, the Municipality has created cottage kits to simplify the management of garbage and recycling. Cottage kits can be purchased at any Municipal office in Wilberforce, Cardiff, or Gooderham. The cottage kits includes a map showing the location of municipal-run landfill locations, Site hours, disposal fees, and recycling guidelines. Additionally, the kits include a landfill pass for a one time admission to any of the landfill sites and includes one clear bag for garbage disposal, two clear blue bags for recycling, and one sturdy bag for fibres. A total of 254 cottage kits were sold in 2018.

In 2010, the Municipality joined together with the other municipalities of the County of Haliburton to receive funding through the Continuous Improvement Fund (CIF) program. The joint venture was initiated such that a Municipal Waste Recycling Strategy could be created in order to improve the efficiency and effectiveness of recycling methods in Haliburton County. The Municipal Waste Recycling Strategy was completed December 31, 2010. The Municipalities within the County are working toward implementing the recommendations outlined in the Strategy.

In 2018, the Municipality held three Municipal Hazardous and Special Waste (MHSW) events with assistance from Drain All Limited. Two full day events were held at the Monmouth Site on June 23, and October 27 and one half day event was held at the Glamorgan Site on August 11. Embedded Table 8 provides a breakdown of the MHSW collected in 2018:

Cambium Inc. Page 33 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

In addition to the MHSW collection events held within the Municipality, there were three MHSW collection days held at the Faraday Public Works Yard in Bancroft which residents of the Municipality could participate in. The three events were attended by 440 residents and it was estimated that the following materials were diverted by Municipality:

 31,590 L  2000 kg  54 car batteries

 107 large propane tanks  800 small propane tanks

5.9 Final Cover Integrity

As required by Condition 23 of the PC of A, and amended by correspondence received from the District Manager in Peterborough on December 10, 2009, the final cover integrity is required to be inspected semi-annually. During the site visit conducted in June and November 2018, Cambium staff noted from the areas observed that the integrity of the final cover was compact, well-graded, and vegetated with no erosion or leachate seeps.

5.10 Compliance with Provisional Certificate of Approval

As stated in Section 39 Condition (B) of the PC of A, all groundwater monitoring wells listed in the monitoring program shall be properly protected from damages. During the 2018 sampling events Cambium field staff noted that monitor OW7A requires minor repair, refer to Section 5.7 for further details.

Other than the minor non-compliance noted above, the Site is being operated in compliance with the PC of A.

6.0 Conclusions and Recommendations

Based on the 2018 monitoring program, Cambium makes the following conclusions regarding the Site:

 Groundwater elevations recorded in 2018 indicated that shallow overburden groundwater flowed to the south-southwest, towards the Irondale River. Groundwater in the deep overburden layer flowed to the south.

 Based on the water quality results from 2018 there was a dilute leachate plume emanating from the waste mound towards the south. It is evident that natural attenuation is occurring at the Site as the leachate plume was weak and did not extend laterally much beyond the actual waste pile.

 The water quality at several wells cross-gradient (OW10, OW7B, and OW9) and up-gradient (OW11) of the waste mound were historically observed to be impacted by (a) non-waste related source(s), particularly the deeper portion of the overburden aquifer.

 The 2018 water quality data confirmed that the surface water quality at the downstream monitoring station SP2 was consistent with the background surface water conditions and was not adversely impacted by the waste disposal site.

 The Site was interpreted to be in compliance with Guideline B-7 and the Site-specific trigger mechanisms.

 Approximately 64,303 bags of residential waste (900 tonnes) were transferred from the Site to the Township’s Bicroft waste disposal site in 2018.

 Approximately 111.84 tonnes of blue box materials and WEEE were collected at the Site in 2018.

 As noted by Cambium staff during the 2018 sampling events, a minor repair is required at monitor OW7A to maintain compliance with O. Reg. 903 and the Site PC of A.

Cambium Inc. Page 35 2018 Annual Report, Glamorgan Waste Disposal Site The Corporation of the Municipality of Highlands East Cambium Ref. No.: 7210-003 March 26, 2019

Based on the 2018 monitoring program, the following recommendations were made:

 The monitoring program should be continued in 2018 in accordance with the program outlined in Table 1.

 Monitors OW7A should be repaired in 2018 to maintain compliance with O. Reg. 903 and the Site PC of A.
