i. 2017 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

1. INTRODUCTION

The Armstrong/Spallumcheen Recycling and Disposal Facility (ASRDF) is located within the District of Spallumcheen in the Regional District of North Okanagan (RDNO) at 3367 Powerhouse Road, approximately 2.0 km north of the center of the City of Armstrong.

The legal description of the properties on which the ASRDF is situated is Lots 4 and 5, Plan 2997; Lot 6, Plan 1847; Lot A, Plan 17833; Lot B Plan 1825 except Plan 17833; all of Section 4, Township 35; and that part of Lot 6 on Plan B1525, Plan 185; Section 5 Township 35; Kamloops (formerly Osoyoos) Division Yale District. The RDNO also owns adjacent properties: Lot 2, Plan 21202 (1901 Stardel Drive), Lot 3, Plan 21202 (1872 Stardel Drive), and Lot 1, Plan 12928 (3651 Powerhouse Road) which serve as landfill buffer.

The site, owned by the RDNO, is approximately 17.6 hectares including all nine lots and serves the communities of Armstrong, Spallumcheen, Enderby, Splatsin and Okanagan Indian Reserve, and the surrounding Electoral Area (F). The location plan is presented as part of the 2017 Environmental Monitoring Report.

The ASRDF was operated by GFL Environmental Inc. under a contract with the RDNO during 2018. The Scale Attendant and Inspector positions at the ASRDF were filled by RDNO staff.

The ASRDF has a maximum permitted filling rate of 80 cubic meters per day. The works authorized are a sanitary landfill and related appurtenances.

2. BACKGROUND

The ASRDF operated under “Summer Hours” from March 1, 2018 to November 30, 2018. Under Summer Hours, the facility was open Monday to Friday from 8:00 a.m. to 4:30 p.m. and Saturday and Sunday from 8:30 a.m. to 4:00 p.m. “Winter Hours” were in effect from January 1, 2018 to February 29, 2018 and from December 1, 2018 to December 31, 2018. Under Winter Hours, the facility was open Monday to Friday from 8:00 a.m. to 4:00 p.m. and Saturday 9:30 a.m. to 3:30 p.m.

The ASRDF includes lockable entrance gates, scale house, one vehicle scale (for both inbound and outbound traffic), and electronic weighing and reporting software (Auto Scale 2000). Customers using the facility, with the exception of customers dropping off Blue Bag Recyclables only, are required to stop at the scale house and pay the specified disposal fee based on the type and weight of material disposed. All site visitors, suppliers, consultants and contractors are required to check in and out of the site at the scale house to ensure they are familiar with the emergency, health and safety protocols and so that they are all accounted for at the end of the day.

2017 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

The Regional District of North Okanagan Municipal Solid Waste Management Bylaw No. 2659, 2014, establishes fees and sets standards for the use of recycling and disposal facilities owned and operated by the regional district. The Bylaw was originally adopted in April 2010 and took effect July 5, 2010. The bylaw has been amended on a number of occasions since 2010. A copy of the version of the Bylaw that took effect on January 1, 2016 and was in effect during 2018 is provided as Attachment B.

Prior to 2012, the RDNO solid waste management program operated on a 100 percent user pay system, with no financial contribution from taxation. However, in 2012 the RDNO implemented a region wide tax levy in the amount of $400,000 to provide additional funding for solid waste management. The annual region wide tax levy was $420,000 in 2018.

3. FACILITY OPERATIONS: 2018

This section describes on-site activities during 2018 including disposal methods and recycling initiatives.

3.1 DISPOSAL METHOD

The filling method used at the ASRDF is area fill. The site has two tipping areas, one for residential self-haulers (transfer station area or Residential Drop Off [RDO] facility) with four lock block bays (40 cubic yard containers) and one for commercial haulers (landfill face). At the landfill face, the ASRDF operator pushes the refuse into small lifts and compacts the material according to RDNO operational requirements. The operator uses a steel wheel loader to push and compact the refuse on a daily basis.

Since mid-January 2012, the RDF Operations Contractor (GFL Environmental Inc.) has used an alternate daily cover system at the ASRDF. At the end of each operating day, after the days refuse is compacted, large steel plates are placed over the active face. The steel plates take the place of daily cover. The steel plate system, known as the ‘Revelstoke Iron Grizzly”, has significantly decreased the need for cover soil at the ASRDF, has decreased the rate at which airspace is being consumed and has increased operational efficiency.

The availability of good cover material for intermediate or side cover is an ongoing challenge at the ASRDF, however stockpiled clay material from excavating cells 5 to 7 is available but difficult to dig and haul to the face. Chipped wood waste mixed with soil is often used for cover at the ASRDF. Soil is accepted at the ASRDF at no charge or at a nominal charge and managed according to RDNO policy and procedures and the OC.

3.2 RECYCLING

The following commodities are segregated at the ASRDF and shipped off-site for recycling or are reused on-site:

• Batteries: all types of batteries (household and automotive) were accepted and stored in secure containers (to prevent theft) and sold to recyclers (not necessarily under the Provincial EPR programs). NOTE: Batteries were no longer accepted as of November 21, 2018. • Tires: passenger and truck tires with and without rims were accepted near the RDO and recycled under the Provincial Tire Recycling Program. • Yard and Garden Waste: yard and garden waste was stockpiled and ground by the RDNO’s grinding contractor. Ground yard and garden waste was mixed with soil and used for cover. • Wood Waste: dimensional wood waste (clean and dirty) was stockpiled at the site and ground by RDNO’s grinding contractor on a regular basis prior to being used on site for cover, bio-filtration and aesthetics on finished slopes. • Propane Tanks: various sizes of tanks (1lb to 40lb) were received and stockpiled. The tanks were removed by a contractor for recertification or recycling. • White Goods and Other Metals: refrigeration units were decommissioned and refrigerant removed by a qualified contractor under contract before being added to the scrap metal stockpile. Scrap metal was sold to a recycling contractor. • Blue Bag Materials: Collected at a location adjacent to the scale house at a Recyclable Materials Drop Center. Blue Bag materials and OCC were transported to a materials recovery facility (MRF) for processing and marketing. • Glass Jars and Bottles: glass jars and bottles were collected in a small roll off container situated near the Recyclable Materials Drop Centre. This material was added to the crushable material pile, crushed and used onsite for roads and tipping pads. • Concrete and other Crushable Material: crushable material was stockpiled and crushed for use onsite for roads and tipping pads. • Styrofoam: waste Styrofoam was accepted from residents and businesses at a nominal charge and transferred to the GVRDF where it was densified using a RecycleTech XT- 200. The ‘ingots’ (blocks of dense Styrofoam) were shipped to market.

3.3 QUANTITIES AND SITE LIFE

The quantity of Municipal Solid Waste (MSW) disposed at the ASRDF in 2017 was 13,035 tonnes, an increase of approximately 0.57% from 2016. This includes the small quantity of refuse transferred from the Kingfisher Transfer Station. There has been a significant increase in disposed tonnage at the ASRDF since 2015 which can be attributed almost entirely to a change in ownership of a local waste management company. MSW from the Electoral Areas B and C which had previously been disposed at the Greater Vernon Recycling and Disposal Facility (GVRDF) by the previous owner prior to 2015 has been disposed at the ASRDF since 2015.

According to 2016 census data, the population in the service area for the ASRDF (Armstrong, Spallumcheen, Enderby, Splatsin First Nation, parts of Rural Enderby (Electoral Area F), parts of the lands is estimated at 17,184. The per capita disposal rate in 2018 was 0.76 tonnes, a slight increase from 2017 but significantly higher than in recent years. The likely reason for this increase is explained in the previous paragraph. It is difficult to determine the number residents in Electoral Areas B and C whose MSW was disposed at the ASRDF starting in 2015 that has previously been disposed at the GVRDF. The per capita disposal rate in this area had been relatively stable for a number of years. When compared with the 1991 estimated per capita disposal rate of 1.06 tonnes per capita per year, the 2017 per capita disposal of 0.75 tonnes per capita per year represents an improvement, but indicates that there is room for increased waste diversion in the Greater Armstrong area are effective.

The most recent evaluation of the remaining site life was completed as part of the 2017 update of the Design, Operations and Closure Plan (DOCP) by GHD Consultants (GHD). In the updated DOCP, GHD re-evaluated the parameters (compaction, cover ratio, etc.) and as of 2018, the facility is estimated to reach design capacity in 2025.

3.4 FACILITY OPERATION AND MAINTENANCE EXPENDITURES

Total operation and maintenance expenditures at the ASRDF during 2018 were $912,144.05.

4. OPERATIONAL MONITORING/INSPECTIONS

RDNO staff closely monitored all aspects of ASRDF operations during 2018 to ensure that operations were carried out in compliance with all Ministry of Environment and Regional District of North Okanagan requirements. Any operational issues noted were addressed as necessary.

5. ENVIRONMENTAL MONITORING

5.1 2018 ANNUAL ENVIRONMENTAL MONITORING REPORT

The Armstrong/Spallumcheen Recycling and Disposal Facility, 2018 Environmental Monitoring Report, April 2019, prepared by Regional District of North Okanagan staff, is provided as Attachment A. The monitoring program is described and monitoring results are provided including the status of sampling points and recommendations for monitoring program improvements, where necessary.

5.2 GROUND AND SURFACE WATER MONITORING RECOMMENDATIONS

a) Continue with the currently established sampling program, and assess trends of exceedances and property boundary conditions.

b) Evaluate potential trends in 2019 for Boron, Cadmium, Chloride, Conductivity, Iron, Magnesium, Manganese, Nitrate, Selenium, Sodium, Sulphate, TDS, and Uranium.

c) Assess and report on the options for resolving leachate migration issues and leachate plume changes around the ASRDF.

5.3 LANDFILL GAS MANAGEMENT

In accordance with the OC and the Landfill Gas Mitigation Plan all probes at the ASRDF were sampled and results recorded. For a summary of 2018 methane readings for the compliance wells see Table 1, and for a site map of the Landfill Gas monitoring wells see Figure 1. Table 1 shows the results of the compliance monitoring wells quarterly in percent methane. Wells shown without data had water levels that were too high for gas sampling, or were damaged, at time of monitoring. The monitoring wells with methane detected continue to show similar levels to the previous year.

In late 2018, six landfill gas passive vents (GW18-01, GW18-02, GW18-03, GW18-04, GW18- 05, and GW18-06) were installed to mitigate the lateral movement of landfill gas by passively venting gas and relieving pressure in the waste. These passive wells are also monitored monthly. The results of the first monitoring event in December 2018 are included in Table 2 below. Monitoring was not completed for GW18-04 as the sampling port on this vent had not been installed yet.

During the June 2018 monitoring event, 0.9% methane was detected in compliance well VP11- 16A. The methane level in this well was tested again the following day, after a re-calibration of the monitoring equipment, and the methane level detected was 0.3%. One week later, the

5.4 EROSION

No erosion was detected on-site in 2018.

5.5 LITTER, DUST AND VECTOR CONTROL

Dust was not a problem at the facility in 2018 except when wood waste was ground. To control dust from the wood grinding process, the wood grinding contractor used water from an on-site hydrant. Litter was collected by the ASRDF contractor when necessary especially after wind events at least within 100 m radius from the site (as per contract requirements). The operator is required to collect litter on a regular and frequent basis. Birds and other vectors were not a problem in 2018.

5.6 LEACHATE MANAGEMENT

As decided in 2016 a combination of evaporation and phytoremediation has been chosen as the best method to manage leachate generated at the ASRDF due to its low long-term capital and operational costs and its sustainability for both the active and post-closure life of the landfill. Also, the RDNO has experience for the last 10 years with managing a phytoremediation program at the site. The development of a new evaporation pond is underway. A new phytoremediation plantation was planted in early 2017.

A Sure pump was used to maintain an operational depth of 0.3 m above the top of the sump elevation in Cell 5. The amount of leachate pumped from the base of the landfill in 2018 was 492,861 USG (1,865 m3).

The leachate storage pond has a finite storage capacity and fills with precipitation as well as leachate. In order to manage the level in the leachate pond, the leachate has been used to water a plantation of hybrid poplars. Irrigation with leachate is authorized in the OC. The new hybrid poplar plantation was planted in 2017 to evapotranspirate the leachate and to store any contaminants in the root nodules. The plantation consists of almost 500 trees, over an area of 7,500 m2. A total of approximately 1,393,032 litres of leachate was applied to the hybrid poplar plantation through individual emitters in 2018.

For the annual monitoring report for the plantation soils please see Attachment B.

The following 2019 recommendations are provided for the watering and monitoring of the Poplar Tree Plantation.

1. Continue the currently established soil monitoring program at the new plantation in 2019, as follows: 2. Soil monitoring should be conducted twice during the irrigation season – prior to startup in the spring and after shutdown in the fall.

8

2017 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

3. Spring soil monitoring in 2019 should be done at the 0-15 cm depth only and in the irrigated area of the site only. 4. Soil monitoring in fall 2019 should be done at 0-15 cm, 15-45 cm and 45-90 cm depths on irrigated and non-irrigated areas of the property. It should be done as 8 subsamples at the 0-15 cm depth and 4 subsamples at the 15-45 and 45-90 cm depths. 5. Analyze the shallow soil samples (0-15 cm depth) in spring and fall for Nitrate-N, ammonium-N, P, K, Ca, Mg, S, Na, Cl, B, Mn, Zn, Cu and Fe, CSR trace elements, and quality parameters: Sodium Absorption Ratio (SAR), pH and conductivity (same parameters as in 2018). 6. Analyze the deep soil samples (15-45 and 45-90 cm depths) for nitrate-N, sulphate-S, conductivity, pH, chloride and SAR (same parameters as in 2018).

5.7 TOPOGRAPHICAL SURVEY

Over the past few years, a number of different aerial and ground surveys of the ASRDF have been undertaken. In the spring of 2018, Aero Geometrics completed an aerial survey of the ASRDF. Aero Geometrics also completed an aerial survey of the ASRDF in the spring of 2017. Based on these two surveys, the airspace consumed between May 21, 2017 and May 12, 2018 was 31,290 m3. The actual airspace consumed by the landfilling of Municipal Solid Waste may vary somewhat from this number as the aerial survey also calculates the volume of other commodities present at the facility at the time the aerial survey is completed. The RDNO plans to undertake another aerial survey of the ASRDF in the spring/summer of 2019.

6. FINANCIAL

Approximately $11,954 was spent on environmental monitoring at the Armstrong/Spallumcheen Recycling and Disposal Facility in 2018.

A Statutory Closure Reserve was established in 2010 for closure and post closure costs at all RDNO Recycling and Disposal Facilities. The balance in the Statutory Closure Reserve at the end of 2018 was approximately $7,036,000. The annual contribution to the Statutory Closure Reserve for 2018 will be $17/tonne of material disposed at all RDNO Recycling and Disposal Facilities in 2018. It is estimated that this amount will be approximately $711,000 which will bring the reserve balance to approximately $7,747,000.

It is estimated that the annual contribution to the Statutory Closure Reserve for 2019 will be close to $768,000 based on current and projected disposed tonnages.

7. DESIGN, OPERATIONS AND CLOSURE PLAN

9

2017 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

An updated Design, Operations and Closure Plan (DOCP) for the Armstrong Spallumcheen Recycling and Disposal Facility was completed by GHD Consultants in 2017 and was submitted.

The DOCP update includes early closure of the northern unlined portion of the Landfill that will allow the RDNO to maximize the landfill capacity and will reduce the long-term leachate generation in the unlined portion of the landfill. This document provides an update to the Operations and Closure Plan prepared by XCG Consultants Ltd. and dated December 20, 2012 (2012 O&C Plan) and has been based on recent and planned site developments and remediation activities. The specific updates in the DOCP include the following: 1. Recent waste tonnages 2. Updated apparent density calculations 3. Updated climate data 4. Updated final contours 5. Updated fill plan sequencing 6. Revised Site lifespan analysis 7. Revised final cover design 8. Updated surface water management plan 9. Revised leachate generation estimates to support revised final cover design and contours 10. Updated landfill gas (LFG) generation assessment.

The updates included have taken into consideration, where possible, the guidelines of the recently finalized Landfill Criteria for Municipal Solid Waste, Second Edition (MOE, 2016). Where specific updates were not required, the 2012 O&C Plan remains current.

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

1. INTRODUCTION

The Regional District of North Okanagan (RDNO) conducted the Environmental Monitoring Program (the “Program”) at the Armstrong/Spallumcheen Recycling and Disposal Facility (ASRDF) since 2012. This report summarizes the results of the 2018 Program. Summit Environmental Consultants Inc. (Summit) previously reported on the 2008 to 2012 Programs (Summit 2009, 2010, 2011, 2012, 2013). From 2012 to 2017, water quality samples were analyzed by AGAT Laboratories (AGAT). In 2018, water quality samples were analyzed by ALS Laboratories (ALS).

1.1 SITE LOCATION The ASRDF is located approximately 2 km east of downtown Armstrong on the west side of Powerhouse Road (Figure 1-1). The latitude/longitude of the site is 50°26'49" N and 119°10'6" W and the elevation is approximately 385 meters (m) above sea level (masl) at the scale house. Fortune Creek flows from south to north approximately 150 m to the east of the ASRDF, Deep Creek flows north to south approximately 1000 m to the northwest of the ASRDF, and Meighan Creek is located approximately 1000m to the southwest (Figure 1-1).

1.2 BACKGROUND The ASRDF is a municipal solid waste recycling and disposal facility that serves the City of Armstrong, the Township of Spallumcheen, the Okanagan and Splatsin Indian Bands, the City of Enderby, and Electoral Areas B, C and F. The site has served as the local waste disposal facility for nearly a century. The RDNO obtained ownership and management of the site in 2000 and currently the ASRDF operates under Ministry of Environment (MoE) Operational Certificate (OC) MR15284, issued May 10, 2001 (MoE 2001). Filling at the ASRDF is planned to continue until 2034. The Design, Operations and Closure Plan (DOCP) was updated by GHD Consultants in 2017/18.

The triangular site has a footprint of approximately five hectares. There are seven compacted clay lined landfill cells (Cells 1 - 7) at the facility and three unlined filling areas in the oldest part of the landfill (Areas 8 – 11). The unlined areas are slated for closure in 2018. Leachate generated in the lined cells is directed to a sump in Cell 5 via spine drains at the base of each Cell. The leachate is pumped out of the sump and into a leachate storage pond southwest of the landfill footprint with a storage volume of 4,700 m3 using a SurePump (installed in November 2013) at a rate of about 0.63 L/sec.

A 250 tree hybrid poplar tree plantation (the Lower Powerhouse Road Poplar Plantation) was established on the west side of the site in 2005 and was irrigated by leachate pond water mixed with domestic water from approximately April to August for twelve years, until it was harvested in 2017. A new plantation was planted in early 2017, on the south-west side of the site. This new plantation has almost 500 hybrid poplar trees, and was irrigated with leachate pond water and

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility freshwater from May to September in 2018 with a total leachate application volume of approximately 1,393,032 litres over 120 days. The soil was sampled before and after the irrigation season and these results are available as Attachment B to the Cover Report of this Annual Report.

Currently, environmental monitoring is conducted at the site three times annually and consists of groundwater sampling and analysis from fourteen monitoring wells, one leachate storage pond, and one domestic well.

1.3 OBJECTIVES AND SCOPE The objective of conducting the Program for the ASRDF is to provide consistent and accurate long-term monitoring of potential environmental impacts from landfill operations at the site. These monitoring and reporting activities were planned in accordance with OC MR 15284 (MoE 2001). In meeting these objectives, the RDNO’s scope of work included the following activities:

• Water sampling performed by RDNO’s Engineering Technician, as scheduled for the year • Tabulating the 2018 water quality data (prepared with the assistance of Wireless WaterTM data management services) • Summarizing water quality guideline exceedances from the 2018 results • Analyzing temporal and spatial data trends • Preparing an annual Environmental Monitoring Report.

1.4 CLIMATE Climate data is available for Vernon (Climate STN ID 1128583) and this data is used as an approximation to the site as the station is located in the same geographic area (approximately 14 km to the southwest) with an elevation of 512 m. The average annual temperature and total precipitation is 8.8°C and 487 mm/year respectively (Environment 2018). Mean monthly temperatures range from -2.8°C in January to 21.0°C in July. The mean monthly total precipitation rates range from 25.2 mm in February to 57.5 mm in November. Values are based on data from 1981 to 2010, and are shown in Table 1-1.

1.5 GEOLOGIC AND HYDROGEOLOGIC SETTING The geology of the North Okanagan consists of a deep bedrock valley overlain by sedimentary deposits laid down prior to and during the last glacial period. At the ASRDF, the bedrock geology is comprised of granite and alkali feldspar of the Mesozoic to Cenozoic Era (MoE 2011). The Okanagan fault is located 160 m north of the site and runs southwest to northeast. The bedrock geology north of the fault is greenstone metamorphic rock of the Paleozoic Era. The bedrock at the site is overlain by approximately 400 m of sediment comprised of various layers.

The Fortune Creek alluvial fan aquifer that underlies the site consists of up to 30 m of sand and gravel. The ASRDF is located on a slightly elevated lacustrine silt bench that has been eroded on all sides by various paleo-versions of Fortune Creek. This creek’s fan sand and gravel deposits are therefore found overlying the glacio-lacustrine silts and clay surrounding the elevated bench. The bench silts contain varying amounts of clay and fine sand. Fine sand lenses in the silt deposit facilitate groundwater flow, possibly resulting in flow velocities that are faster than normally found in lacustrine silts. Deeper layers of interbedded sands and silts of the Okanagan Valley Fill Complex are present below the Fortune Creek alluvial aquifer, in the upper unit Bessette sediments called the Spallumcheen Aquifer.

1.6 REGULATORY FRAMEWORK As per the requirements of the OC MR 15284 (MoE 2001):

“landfills must be operated in a manner such that ground or surface water quality does not decrease beyond that allowed by the Water Quality Guidelines (Criteria) and A Compendium of Working Water Quality Guidelines for British Columbia: 1998 Edition…If excursions result to the specified water quality criteria, the Regional Waste Manager may require that leachate management control measures or works be undertaken.”

The water quality data have been compared to the following BC drinking water, aquatic life, livestock, and irrigation guidelines, due to the proximity of domestic wells, surface waters, and surrounding farms to the ASRDF and because accumulated leachate is used in spray irrigation at the onsite poplar tree plantation:

• British Columbia Approved Water Quality Guidelines for freshwater aquatic life (BCAWQG AL) • British Columbia Working Water Quality Guidelines for freshwater aquatic life (BCWWQG AL) • British Columbia Approved Water Quality Guidelines for irrigation (BCAWQG I) • British Columbia Working Water Quality Guidelines for irrigation (BCWWQG I) • British Columbia Approved Water Quality Guidelines for livestock (BCAWQG L) • British Columbia Working Water Quality Guidelines for livestock (BCWWQG L) • British Columbia Source Drinking Water Quality Guidelines Maximum Acceptable Concentrations (BC SDWQG MAC)

2. FIELD INVESTIGATION METHODS

2.1 MONITORING NETWORK The 2018 Program consisted of sampling fourteen groundwater monitoring well locations (Dinwoodie Well, MW03-7A, MW04-12A, MW-12B, MW06-14, MW06-15B, MW06-16, MW06-19, MW-5, MW10-01, MW10-02, MW10-03, MW13-01, and MW16-01). Figure 1-1 shows the well locations. Leachate samples were also collected from the Leachate Pond (Figure 1-1) during the spring sampling event. The history of the monitoring program at the ASRDF is as follows:

• Six monitoring points were specified for the ASRDF according to the OC. These were monitoring wells MW-1, MW-3, MW-4 and MW-5, domestic well DMW-1, and a surface water sample from the Leachate Pond (SW-1). In 2003, additional monitoring wells (MW- 6, MW03-7A, MW-7B, MW-8, MW-9, MW-10 and MW-11) were installed at locations around the ASRDF by BGC Engineering Inc. (BGC 2004). • In 2004, up-gradient monitoring wells MW-10A (shallow) and MW-10B (deep) (replacement wells for MW-10) and down-gradient wells MW04-12A (shallow) and MW- 12B (deep) were installed and added to the 2005 monitoring program. • Domestic well DMW-1 was removed from the monitoring program beginning in 2004 at the request of RDNO and was decommissioned when Cell 7 was constructed. • Monitoring wells MW-6, MW-8, MW-10 and MW-11 were removed from the sampling program in 2005. In 2006, down-gradient wells MW-13, MW06-14, MW06-15A, MW06- 15B, MW06-16, MW06-17, MW06-18 and MW06-19 were installed around the ASRDF by BGC Engineering Inc. (BGC 2006). • Down-gradient wells MW-3 and MW-5 were removed from the 2006 sampling program. • In 2007, 2008, and 2009 the monitoring program was reduced to a limited number of sampling points as requested by RDNO. Monitoring wells MW-1, MW-4, MW-10A, MW10- B, MW-12B, MW-13, MW06-15A, and MW06-17 were discontinued beginning in 2007. In 2008, sampling of MW-7B and MW-9 was discontinued. In 2009, MW-5 was added back into the program. • In 2010, samples were collected from three domestic water supply wells (the Dinwoodie well, the Ambrosi well, and the RDNO well). Late in 2010, Golder Associates installed three new monitoring wells (MW10-1, MW10-2, MW10-3), as well as multiple in-situ gas sampling wells. • In 2011, the newly installed wells were included in the monitoring program (MW10-1, MW10-2, MW10-3), while the Dinwoodie well, the Ambrosi well, the RDNO well, and MW06-18 (replaced by MW10-3) were discontinued as sampling locations. • In 2012, monitoring of gas wells was conducted by the RDNO. In July 2012, two additional leachate samples, LEW04-1 and LEW04-2, were collected as one-time samples. • In 2013, MW13-01 (Figure 1-1) was drilled in October to determine if there was leachate running laterally below the poplar plantation. This well was included in the fall 2013 monitoring program and will continue to remain in the program.

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

• In 2015, MW-12B and the Dinwoodie well were added back into the program due to the leachate outbreak in the area of MW04-12A and MW-12B. These two wells will continue in the program. • In June 2016, MW16-01 was drilled to confirm groundwater flow direction and property boundary conditions. A landfill gas monitoring well, VP11-14B, was sampled for groundwater in November of 2016 to determine groundwater conditions in the southeast corner of the site. Water quality results from this well were reported as VP11-14B (W). This well was damaged in the spring of 2018 and will no longer be sampled.

A list of wells that are currently being used for the Program and wells that have been removed from the Program over time is provided in Appendix A. Wells that are not to be sampled have a strikethrough.

2.2 MONITORING DATES In 2018, samples were collected in May, August, and October. In November 2009 Summit performed a statistical Analysis of Variance (ANOVA) test on the water quality data set from the ASRDF. The analysis demonstrated there was no significant difference in the water chemistry when samples were taken quarterly versus tri-annually. The results of the ANOVA test were accepted by the MoE to reduce the overall sampling events from quarterly to tri-annually, beginning in 2011.

2.3 SAMPLING METHODS This year sampling was completed by Ms. Jamie Jaffary, RDNO Engineering Technician. The same sampling protocols have been completed by the RDNO technicians since 2012. The sampling protocols followed provincial standards (MoE 2013) and meet the intent of the OC.

Static groundwater levels were taken at all monitoring wells using a water-level meter. RDNO sampling techniques utilize low flow methods which include: a peristaltic or bladder pump, a bailer, or waterra with a foot valve, or running tap water from a domestic well. The low flow method is used, where possible, to minimize disturbance and sample turbidity. Dedicated or one-time usage low density polyethylene (LDPE) tubing was used during sampling. The surface water leachate pond sample was obtained using a sampling arm to obtain a dip sample from the pond.

The 2018 sampling procedure used to sample groundwater from monitoring wells involved purging the well, while monitoring and recording field parameters (groundwater level, Electrical Conductivity (EC), Dissolved Oxygen, pH, and Temperature), until consistent water chemistry was obtained, at least three well volumes had been purged, or the well went dry. The depths to water measurements were recorded during the purging process to ensure water was being drawn from the aquifer rather than the water column.

Once the equilibrium of the field parameters stabilized, or at least three well volumes had been purged from the well, groundwater samples were collected. Samples were collected in laboratory-

8

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility supplied sampling bottles, and preserved as required. Samples were stored in ice-filled coolers to maintain the temperature below an average of 10°C and submitted to ALS Laboratories in Burnaby, B.C for analysis within the required holding times. Samples collected for dissolved metals analysis were field-filtered using single-use Henke Sass Wolf Syringes and 0.45 micrometre (µm) Sartorius filters at the time of sampling.

Quality assurance and quality control (QA/QC) field measures implemented during the sampling event include: using site-specific field forms, wearing nitrile gloves, and using either sampling supplies that are dedicated to the well, or cleaning the equipment between wells with Liquinox and rinsing with de-ionized water thereafter. Properly completed chain-of-custody forms accompanied each sample sent to the lab. In addition to field QA/QC, an internal laboratory QA/QC program was followed which included analysis of reference samples, blanks, matrix spikes and laboratory duplicates. ALS Laboratories performed analysis for the groundwater samples submitted for testing and they have achieved certification by the Canadian Association for Laboratory Accreditation Inc. (CALA) for the analyses conducted.

2.4 SAMPLING PARAMETERS The 2018 analytical program included the following:

• Field parameters (pH, Conductivity (EC), Temperature, Dissolved Oxygen) • Routine laboratory parameters (pH, Conductivity (EC), Hardness, and Turbidity) • Dissolved anions and cations (Alkalinity, Chloride, Fluoride, and Sulfate) • Nutrients (Ammonia, Nitrate, Nitrite, Total Kjeldahl Nitrogen (TKN), Total Phosphorus) • True Colour • Dissolved metals (groundwater samples only) and total metals (leachate sample only) • Chemical Oxygen Demand (COD) • VHw (6-10) and VPHw • Benzene, Ethylbenzene, Toluene, and Xylene (BTEX) and Methyl Tert-Butyl Ether (MTBE) • Fecal Coliforms.

This is the same suite of parameters analyzed during previous monitoring programs. Total Dissolved Solids (TDS) was not analyzed in 2018, due to a mistake in the requested analysis during the change in laboratories that occurred in 2018. TDS will continue to be analyzed in 2019.

2.5 FIELD OBSERVATIONS During field visits, vegetation around the ASRDF was observed for signs of stress and/or mortality. Examples of such signs include discolouration and plant mortality. The area is also observed for signs of liquid flowing from or along the surface which could indicate leachate breakout.

3. MONITORING RESULTS

3.1 VEGETATION AND EROSION No indications of erosion or stressed vegetation on the landfill footprint were observed during the 2018 site visits.

Following the leachate outbreak in spring of 2015 (RDNO 2016), the newly constructed collection pond (Lower Powerhouse Road Pond or LPR Pond) has been monitored weekly by site staff. The LPR Pond level is recorded weekly and approximately 465,000 L was removed in 2018 and disposed on site in the vicinity of the Cell 5 sump using a septage pumping and hauling truck (Le Pew Septic Services, or Affirmative Contracting Inc.). When the road to the Leachate Storage Pond is trafficable, the hauling truck disposes directly into this pond.

Two geotechnical wells (BH18-01 and BH18-02) and one borehole (BH18-03) were drilled in November/December of 2018 as part of the slope stability project for the embankment on the north tip of the site. Slope inclinometer readings were taken at BH18-01 and BH18-02 at the top of the slope, and this measurement will set a benchmark for future ground movement. The slope will be repaired as part of the Phase 1 Landfill Closure project in 2019. This will entail a ditch network on top of the landfill and a swale to a manhole on the lower road, with an overflow to a shallow unlined pond in the adjacent field (buffer owned by RDNO) for clean storm water only.

3.2 MONITORING WELL STATUS All of the monitoring stations were accessible in 2018 and are considered adequate to meet the objectives of the monitoring program, except VP11-14B (W). VP11-14B (W) was filled with sand from the surrounding well pack from a loose connection in the PVC pipe and was therefore not able to be sampled. All wells had good recharge and sufficient water to sample with the exception of MW13-1. MW13-1 was dry at the August and October sampling event. For select wells, odours and/or turbid water were reported. The following list highlights observations in 2018:

• MW03-7A was slightly silty during the August sampling event. • MW04-12A had a slight to moderate garbage/sulphur odour and yellow colouring during purging and sampling at all sampling events. Some suspended solids and were observed during purging and slightly silty water at sampling in May. • MW-12B had a moderate garbage odour and yellow colouring during purging and sampling at all sampling events. Some suspended solids were observed during purging and sampling in August and October. • MW-5 had slightly silty water during purging and sampling in May, August, and October and a slight Sulphur odour at sampling in May. • MW10-01 had some suspended solids and slightly turbid water during sampling in August and October, and a moderate to strong sulphur odour in October. • MW10-02 was moderately silty during purging in May, but cleared by sample time. During sampling, there was a slight sulphur odour. In August, the water was slightly silty and had

10

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

an earthy odour during sampling. In October, the water was slightly silty during sampling with no odour. • MW10-03 was slightly silty with a slight sulphur odour during sampling in May. In August, the water was slightly silty and had a moderate sulphur odour during purging and sampling. In October, the water was very silty during purging, and cleared to moderately silty by sampling. There was a slight garbage odour observed in October. • MW16-01 had some suspended solids in August and was slightly silty in October during purging.

3.3 WATER LEVELS Groundwater elevations were calculated by subtracting the field measured depth to water from the surveyed elevation at the top of casing. Table 3-1 presents the top of casing elevation, the measured depth to water, and the calculated groundwater elevation for wells sampled in 2018. Figure 3-1 shows the change in groundwater elevation from 2013 to 2018.

Groundwater levels appear to be stable over time, with minor seasonal fluctuations within wells, and MW10-03 showing a slight decreasing trend over time (Figure 3-1). Most wells show a decrease from spring to fall. Water levels observed in 2018 were consistent with previous years. Based on these groundwater elevations, groundwater flow is generally toward the northwest.

3.4 QUALITY ASSURANCE/QUALITY CONTROL To assess the quality of the sampling and analytical results, field duplicates were analyzed for the Program at a rate of approximately 10% of the total number of samples collected. A duplicate sample is where a field sample of water is collected, and split into two equal samples. One of these samples is the duplicate sample and is submitted to the analytical laboratory under a separate label so the laboratory has no knowledge of the site the sample came from. The collection and analysis of the duplicate samples provides information on the combined (field and analytical) precision of the sampling and analytical program. The individual analytical results of each of the samples of the duplicate pair were compared and the relative percent difference (RPD) was calculated for each analyte pair. RPDs were calculated using the following formula,

Where a and b are duplicate pair values in identical units.

An RPD of 25% or less is generally considered acceptable while an RPD of greater than the 25% limit may indicate a problem in either sampling or analysis (MoE 1998). This limit may vary somewhat depending on the analysis involved and the concentration of the analyte. The RPD also tends to increase as the result approaches the detection limit. Therefore, use of this threshold is restricted to values that are over five times their detection limit.

Caro Analytical Laboratories completed analysis on samples from 2008 to 2011. AGAT Laboratories completed analysis on samples from 2012 to 2017. ALS Laboratories completed analysis on samples in 2018.

Duplicate samples collected from the ASRDF were used to assess the quality of the sampling and analytical results. For the ASRDF, a total of three samples were submitted for duplicate analysis from Dinwoodie, MW03-7A, and MW-5 in May, August and October. The calculated RPD for Nitrite was greater than the 25% threshold in October. The normal and duplicate values for Nitrite are within an order of magnitude of each other; therefore it is not a concern. Sample heterogeneity is considered a possible cause of the high RPDs.

3.5 EXCEEDANCE SUMMARY The water quality results from 2016 to 2018 were compared with the guidelines and are presented in Appendix B. All historical data is available if needed. The original laboratory reports are included in Appendix C.

Ammonia. Ammonia exceeded the BCAWQG AL and the BC CSR AW in 2018 in the Leachate Pond, MW04-12A, and MW-12B. Due to no apparent aquatic habitat being influenced by the landfill, these exceedances are not a concern at this time.

Arsenic (Dissolved). Arsenic in MW-5, MW03-7A, MW04-12A, and MW10-03 exceeded the BCAWQG AL in 2018. Arsenic in MW-12B exceeded the BCAWQG AL, the BC SDWQG MAC, and the BC CSR DW in 2018. Due to no apparent aquatic habitat being influenced by the landfill, these aquatic life exceedances are not a concern at this time. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for human-use or crops (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for livestock watering and irrigating is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer). The Arsenic concentration in MW-5 (background well) suggests Arsenic could be naturally occurring in the surrounding soils.

Arsenic (Total). Total Arsenic in the Leachate Pond in 2018 exceeded the BCAWQG AL, the BC SDWQG MAC, and the BC CSR DW. As the pond is not used for drinking water purposes and no apparent aquatic habitat is being influenced down-gradient of the landfill, these exceedances are not a concern at this time.

Boron (Dissolved). Boron concentrations remained elevated and exceeded the BCAWQG AL, the BCAWQG I, and the BC CSR IW in MW04-12A and MW06-16 in 2018. MW06-16 exceeded only the BCAWQG I and the BC CSR IW in 2018. Due to no apparent aquatic habitat being influenced down-gradient of the landfill, the aquatic life exceedances are not a concern at this time. As groundwater is not used for irrigation in the ASRDF northwest buffer (northwest plume area), the irrigation exceedances are also not a concern at this time.

Boron (Total). Total Boron in the Leachate Pond in 2018 exceeded the BCAWQG AL, the BCAWQG I, and the BC CSR IW. Due to no apparent aquatic habitat being influenced down- gradient of the Leachate Pond, the aquatic life exceedance is not a concern at this time. No livestock or human use crops are irrigated with the Leachate Pond water, therefore, the irrigation guideline exceedance is also not a concern at this time.

Chloride. Chloride concentrations in wells MW04-12A, MW06-14, MW06-15B, MW06-16, MW16- 01, MW10-01, MW13-01, and the Leachate Pond exceeded at least one applicable guideline for aesthetic objective, aquatic life, irrigation, livestock, and drinking water in 2018. Most of these wells are located down-gradient of the landfill. The highest concentrations of Chloride were found within MW06-16, MW04-12A, and the Leachate Pond. Chloride concentrations are generally greater in wells located down-gradient of the unclosed and unlined portion of the landfill (migration through the thalweg). Based on available information to date, these exceedances appear to be landfill related. Due to no apparent aquatic habitat being influenced down-gradient of the landfill, the aquatic life exceedances are not a concern at this time. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking, livestock watering or for irrigation of livestock or human use crops (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for livestock watering and irrigating is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer).

Chromium (Dissolved). In 2018, Chromium concentrations exceeded the BCWWQG AL in MW06-14, MW06-19, MW10-02, and MW13-01. Due to no apparent aquatic habitat being influenced by the landfill, the aquatic life exceedances are not a concern at this time. Groundwater from the aquifer of the up-gradient well, VP11-14B (W), is not used for irrigation or drinking water and is therefore not a concern at this time.

Chromium (Total). The Leachate Pond exceeded the BCWWQG AL, the BCWWQG I, the BC CSR AW, and the BCC CSR IW for Total Chromium in 2018. As no livestock or human-use crops are irrigated with Leachate Pond water and no apparent aquatic habitat is being influenced down- gradient of the Leachate Pond, these exceedances are not a concern at this time.

Cobalt (Dissolved). Cobalt concentrations in MW04-12A, MW-12B, MW06-16, and MW10-02 exceeded the BC CSR DW in 2018. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for drinking is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer), therefore these exceedances are not a concern at this time.

Cobalt (Total). The Leachate Pond exceeded the BCC CSR DW for Total Cobalt in 2018. As the pond is not used for drinking water purposes, these exceedances are not a concern at this time.

Colour. Colour exceeded the BC SDWQ AO in the Leachate Pond, MW04-12A, and MW-12B in 2018. This is not considered a concern as the exceeded guideline is intended for aesthetic considerations and the groundwater in the northwest plume area and the Leachate Pond water is not being treated for use as a drinking water supply.

Conductivity. Laboratory and field Conductivity concentrations exceeded the BCWWQG I in the Leachate Pond and all monitoring wells, except the Dinwoodie Well, MW-5, MW03-7A, and MW12B in 2018. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for livestock watering or for irrigation of livestock or human use crops (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for livestock watering and irrigating is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer), therefore these exceedances are not a concern at this time.

Dissolved Oxygen. Field measurements of Dissolved Oxygen exceeded the BCAWQG AL in all monitoring wells except MW10-03 in 2018. This parameter is a field measured parameter and is highly variable. The exceeded guideline is designed for surface water bodies and not groundwater, and due to no aquatic life being influenced by the landfill, these exceedances are not a concern.

Fecal Coliforms (Counts). The Leachate Pond, and MW06-19 exceeded the BC SDWQG MAC for Fecal Coliforms in 2018. The Leachate Pond is considered an open surface water body, and in turn is susceptible to influence from external sources other than those observed from landfill operations. During the sampling events of previous years, birds were observed to be in and/or near the Leachate Pond and surrounding area, which could potentially be the point source of the Fecal counts. Since the pond water is not used for drinking purposes, this exceedance is not a

17

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

concern. MW06-19 exceeded a guideline for the first time in 2018. As groundwater at or near this groundwater well is not used for drinking water or livestock purposes, this exceedance is not a concern at this time, but will be closely monitored in the future.

Iron (Dissolved). In 2018, Iron concentrations exceeded the BCAWQG AL and the BC SDWQG AO in MW04-12A, MW-12B, MW10-01, MW10-02, and MW10-03. As the drinking water guideline is designed for aesthetic considerations and the groundwater does not influence aquatic habitat, these exceedances are not a concern at this time.

Lithium (Dissolved). Lithium concentrations exceeded the BC CSR DW in MW04-12A, MW06- 16, and MW10-03 in 2018. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for drinking is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer), therefore these exceedances are not a concern at this time.

Lithium (Total). The Leachate Pond exceeded the BCC CSR DW for Total Lithium in 2018. As the pond is not used for drinking water purposes, this exceedance is not a concern.

Manganese (Dissolved). Manganese concentrations exceeded at least one applicable guideline in all wells except MW06-14, MW06-19, and MW13-01 in 2018. MW-5, MW06-15B, and MW16- 01 exceeded just the BC SDWQ AO. MW04-12A, MW-12B, MW06-16, MW10-01, and MW10-03 exceeded the BC SDWQG AO, the BCWWQG I, and the BC CSR IW. MW10-02 exceeded the above listed guidelines as well as the BC CSR DW. There does not appear to be any correlation between the well exceedances and landfill activity, as the Leachate Pond has relatively low levels of Manganese and the background well (MW-5) and the deep aquifer well (Dinwoodie Well) are showing exceedances. Therefore, it is assumed that Manganese is naturally occurring in the area.

Manganese (Total). The concentration of Total Manganese from the grab sample at the Leachate Pond exceeded the BCWWQG I, the BC CSR IW, and the BC SDWQG AO in 2018. The pond water is only used to irrigate poplar trees and it is not used for drinking water, therefore, these exceedances are not a concern.

Molybdenum (Dissolved). Molybdenum concentrations exceeded the BC CSR IW in MW03-7A, MW06-15B, MW06-16, MW16-01, and MW10-03 in 2018. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for irrigation of livestock or human-use crops (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for irrigating is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer), therefore these exceedances are not a concern.

Nitrate (as N). Nitrate concentrations in MW06-14, MW06-19, and MW13-01 exceeded the BC SDWQG MAC and the BC CSR DW in 2018. These wells are located on the west side of the landfill, near the poplar tree plantations. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for drinking is considered developed in the lower aquifer that is

18

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

separated from the upper aquifer by a confining layer), therefore these exceedances are not a concern.

Nitrate + Nitrite (as N) (calculated). This parameter exceeded the BC CSR DW in MW06-14, MW06-19, and MW13-01 in 2018. Nitrite concentrations alone did not exceed any guidelines in these wells in 2018, however, with the addition of Nitrate, the same wells exceeding the Nitrate guidelines exceeded this calculated parameter.Nitrite (as N). Nitrite concentrations exceeded the BC AWQG AL in MW-5 in 2018. Due to no apparent aquatic habitat being influenced by the landfill, this exceedance is not a concern at this time. As MW-5 is a background well, Nitrite may be a naturally occurring nutrient in the groundwater.

Selenium (Dissolved). Selenium concentrations exceeded one or more guidelines for aquatic life, drinking water, irrigation, and maximum acceptable concentrations in MW06-14, MW06-15B, MW06-16, MW06-19, MW10-02, and MW13-01 in 2018. MW06-15B also exceeded the BC CSR L and the BCAWQG L. The Selenium exceedances are probably not caused by naturally occurring concentrations in the area as MW-5 (background well) is not showing any Selenium exceedances. The Selenium exceedances are likely caused by landfill activities and will continue to be monitored. One of the exceeded guidelines is for aquatic life and due to no apparent aquatic life habitat being influenced down-gradient, this exceedance is not a concern at this time. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking or irrigation of livestock or human-use crops, therefore, the other guideline exceedances are not a concern at this time (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for irrigating is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer).

Sodium (Dissolved). In 2018, Sodium concentrations exceeded the BC CSR DW in MW04-12A, MW06-15B, MW06-16, and MW10-03. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for drinking is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer), therefore these exceedances are not a concern.

Sodium (Total). The concentration of Total Sodium from the grab sample at the Leachate Pond exceeded the BC CSR DW in 2018. The pond water is not used for drinking, therefore, this exceedance is not a concern.

Strontium (Dissolved). Strontium concentrations exceeded the BC CSR DW in MW06-16 and MW10-03 in 2018. Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for drinking is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer), therefore these exceedances are not a concern.

Sulphate. Sulphate concentrations exceeded one or more guidelines for aquatic life, aesthetic objectives, drinking water, and livestock at MW04-12A, MW06-14, MW06-15B, MW06-16, MW06- 19, MW10-03, MW13-01, and MW16-01 in 2018. Due to no apparent aquatic habitat being influenced by the landfill, the aquatic life guideline exceedances are not a concern at this time.

19

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

Groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking or livestock watering, therefore these exceedances are also not a concern at this time (the down- gradient and cross-gradient domestic well that may be used by Dinwoodie for drinking and livestock watering is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer).

Temperature (Field). In 2018, field measurements of Temperature exceeded the BC SDWQG AO in the Leachate Pond. This parameter is a field measured parameter and is highly variable. The exceeded guideline is for aesthetic considerations and as the pond water is not used for drinking, this guideline exceedance is not a concern.

Uranium (Dissolved). In 2018, Uranium concentrations exceeded two or more applicable guidelines for aquatic life, irrigation, and drinking water in MW06-14, MW06-15B, MW06-16, MW06-19, MW10-01, MW10-02, MW13-01, and MW16-01. All wells continue to vary both spatially and temporally across the site which could indicate that Uranium concentrations are a natural property of the aquifer. Also, groundwater from the upper aquifer in the buffer areas around the ASRDF is not used for drinking or irrigation of crops for human or livestock consumption (the down-gradient and cross-gradient domestic well that may be used by Dinwoodie for drinking and livestock watering is considered developed in the lower aquifer that is separated from the upper aquifer by a confining layer).

Vanadium (Total). The Leachate Pond exceeded the BCC CSR DW for Total Vanadium in 2018. As the pond is not used for drinking water purposes, this exceedance is not a concern.

3.6 TREND ANALYSIS The potential for landfill leachate to affect groundwater is typically assessed by comparing the concentrations of landfill leachate indicators relative to background groundwater concentrations. Typical leachate indicators may include but are not limited to: Ammonia, Chloride, Alkalinity, Sulphate, Manganese, Iron, Calcium, Magnesium and heavy metals including Cadmium, Chromium, Copper, Nickel and Zinc (Christensen et al. 2001).

Graphs of selected leachate-associated parameters and parameters exceeding guidelines were plotted to illustrate temporal and spatial trends (Figures 3-2 to 3-13). On these plots, results that were below detection are circled and plotted as half the detection limit. The order of plots is not significant.

Boron concentrations in MW04-12A, MW06-15B, and MW06-16 have shown high fluctuations over time. MW04-12A is showing a relatively steep increasing trend since 2011. MW06-16 was showing a slight upward trend since approximately 2010, but appears to be leveling off or decreasing in Boron concentration since 2015. The increasing trends noted in these wells in the northwest buffer plume area may be a result of covering the old unlined portion of the landfill with a clay stockpile thereby allowing less infiltration of precipitation and resulting in more concentrated groundwater down-gradient. As the final cover for this area is applied, trending may change again. MW06-15B is showing a decreasing trend since 2013. MW-12B is showing a decreasing trend of Boron concentration since the 2015 sampling. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015. No trends are noted in any of the other sample sites.

The BCAWQG AL and BC CSR AW for Cadmium cannot be depicted on the figure as it is individually calculated for each well based on the water hardness (CaCO3). None of the wells exceeded these guidelines, or any applicable guidelines for Cadmium, in 2018.

Historically, Cadmium concentrations in MW06-16 have been elevated in comparison to other wells in the Program. However, since 2010, values in this well appear to be leveling off with large fluctuations throughout the years. MW06-15B has shown increased concentrations since 2013. Further years of data are needed to determine a trend. MW04-12A showed a sharp decrease in concentration in 2015 and has remained near detection limit since. There appears to be increasing Cadmium concentrations in MW16-01, however, seasonal fluctuation is also apparent. Concentrations in most other wells have remained relatively stable.

The Chloride concentration in MW06-15B is showing a decreasing trend since 2014. MW06-16 had elevated Chloride concentrations in 2013 and 2014, but has been decreasing since and has reached historically low levels in 2018. MW04-12A is showing a decreasing trend since 2012. The previously increasing trends in these wells in the northwest buffer plume were likely a result of covering the old unlined portion of the landfill with a clay stockpile, which allowed less infiltration of precipitation and caused concentrations of some landfill related parameters to increase in the plume area. In 2015, filling began in this area which utilized the clay stockpile, thereby allowing more infiltration of precipitation. This may be causing the decrease in Chloride concentration, and other landfill related parameters, in the northwest buffer plume since 2015. As the final cover for this area is applied in the near future, trending may change again. Since Chloride moves the most quickly of the leachate indicator parameters, it will be the most responsive to changes in landfill operations. MW-12B is showing a decreasing trend in Chloride concentration since the 2015 sampling. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015.

Conductivity in the wells in the northwest buffer area appears to be decreasing since around 2015. These wells include MW04-12A, MW06-16, and MW06-15B. The previously increasing trends in these wells in the northwest buffer plume were likely a result of covering the old unlined portion of the landfill with a clay stockpile, which allowed less infiltration of precipitation and caused concentrations of some landfill related parameters to increase in the plume area. In 2015, filling began in this area which utilized the clay stockpile, thereby allowing more infiltration of precipitation. This may be causing the decrease in landfill related parameters in the northwest buffer plume that we are seeing since 2015. As the final cover for this area is applied in the near future, trending may change again. MW06-14 had a notable increase in Conductivity in 2012, however, the concentration appears to be on a decreasing trend since. MW10-03 has shown a steadily increasing trend since sampling began at this well. MW13-01 has had a decreasing trend in Conductivity since sampling began at this well. Though MW16-01 has only been sampled for three years, it appears to have decreasing Conductivity. Successive years of data are needed to determine whether a trend is present. MW-12B is showing a decreasing trend of Conductivity since the 2015 sampling. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015.

Iron concentrations have remained relatively stable in most wells. Down-gradient wells MW06-16 and MW06-15B have decreased from the elevated concentrations observed when sampling began and have remained below guidelines since 2011. MW04-12A has shown fluctuations in Iron concentration since sampling began but appears to be decreasing since a spike in concentration in 2015. MW10-03 appears to have a slight increasing trend of Iron concentration since sampling began. None of the other monitoring wells have shown an increasing trend. MW- 12B is showing a decreasing trend of Iron concentration since the 2015 sampling. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015.

There are no applicable BC guidelines for Magnesium. Magnesium concentrations in MW04-12A have shown high fluctuations over time with a moderate increasing trend observed from 2006 until 2014. Since 2015, this well has shown decreased Magnesium concentrations. MW06-15B is also showing a decreasing trend since 2015. The removal of the clay stockpile on the north corner of the site in 2015 may be the cause for the decrease in concentrations in these wells in the northwest buffer area, as there will have been more precipitation infiltration and greater dilution of some parameters. MW10-03 is showing a decreasing trend since 2016. An increase in Magnesium concentration was observed in MW06-14 in 2012 and 2013, and the concentration remained slightly elevated until 2017, when it appears to have begun decreasing. More years of data are needed to determine a trend. MW06-16 appears to be on a slight decreasing trend of Magnesium concentration since 2014. MW-12B is showing a decreasing trend of Magnesium concentration since the 2015 sampling. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015.

The BCAWQG AL for Dissolved Manganese cannot be depicted on the figure as it is individually calculated for each well based on water hardness (CaCO3). None of the sample sites exceeded this guideline for Manganese in 2018.

Manganese concentrations in MW04-12A have shown high fluctuations over time with an overall decreasing trend since sampling began. After 2013, the concentration in this well has increased slightly but appears to be stabilizing around the drinking water guideline of 1.5 mg/L. Manganese concentrations in MW10-02 had increasing concentrations in the fall of 2017 and 2018. Further years of data are needed to determine these increases continue. None of the other monitoring wells show an increasing trend. MW-12B is showing a decreasing trend of Manganese concentration since the 2015 sampling. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015.

MW04-12A has remained below detection point since 2015, after having elevated Nitrate concentrations from 2011 to 2014. Nitrate in MW06-19 has decreased since the elevated level seen in 2015, and appears to be slightly increasing. MW06-14 appears to be sharply increasing in Nitrate concentration since 2014, but has not surpassed historical concentrations. Nitrate in MW10-02 has fluctuated between 0 and 10 mg/L but has not exceeded the drinking water guideline. MW13-01 also fluctuates largely year to year, but has exceeded the drinking water guideline for the past two years. Further monitoring is required to determine if a trend is present. These wells showing elevated Nitrate concentrations are located near the leachate pond and the poplar tree plantation that is irrigated with leachate. As the leachate has high concentrations of Ammonia, the groundwater in this area may be affected by the conversion of Ammonia to Nitrate as a product of oxidation. MW06-14, MW13-01 and MW10-02 are located closest to the old poplar plantation that is no longer receiving leachate irrigation as of 2017. Therefore, the Nitrate concentration in these wells may decrease as this site is naturally flushed.

Selenium concentrations have been highly variable throughout the years of sampling. MW06-15B showed a significant increase in 2017 and remained elevated in 2018. More years of data are needed to determine if these increases will become a trend. None of the other monitoring wells show an increasing trend in Selenium. MW04-12A has remained below guidelines since 2014. MW06-14 appears to be decreasing in Selenium concentration since 2012. MW13-01 remained at a decreased Selenium concentration again in 2018, indicating a decreasing trend is occurring since the spike in concentration in 2014, which may have been an anomaly.

MW04-12A has had a decreasing trend in Sodium concentration since 2013, after having a moderate increasing trend since sampling began. MW06-15B also has had a decreasing trend in Sodium concentration since 2013, after showing an increasing trend since 2009. MW06-16 was showing a moderate increasing trend since sampling began, but has shown decreasing concentrations since 2015. As previously mentioned, these wells in the northwest buffer plume are likely showing the results of the removal of the clay stockpile on the north corner of the site, which was previously preventing a portion of precipitation infiltration and increasing the concentration of some parameters in the plume area. The removal of the clay stockpile beginning in 2015 appears to have allowed more precipitation infiltration and therefore diluted the concentration of some landfill related parameters, like Sodium, in the groundwater. MW10-03 has shown a slight increasing trend in Sodium since sampling began at this well. MW13-01 has shown a decreasing trend since sampling began at this well. MW06-14 has shown a slight increasing trend since 2012, but has shown decreased Sodium concentrations in the last three years. None of the other monitoring wells show an increasing trend. MW-12B is showing a decreasing trend of Sodium concentration since the 2015 sampling. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015.

Monitoring of Sulphate began in 2011. MW10-03 has shown a slight increasing trend in Sulphate concentration since sampling began. Sulphate concentrations in MW04-12A have remained around 1500 mg/L since 2015, following an increase in concentration from 2013 to 2015. MW06- 14 has shown a decreasing trend in Sulphate concentrations since 2015, following the increasing trend observed from 2012 to 2015.MW13-01 has decreased significantly since sampling began. MW06-15B is showing a decreasing trend in Sulphate concentration since 2014. The Leachate Pond has also been decreasing since 2012.

Uranium concentrations continue to vary both spatially and temporally across the site. Concentrations in MW06-16 and MW06-15B have typically been elevated, but have remained relatively stable with a maximum range of approximately 0.05 mg/L. Uranium concentrations in these wells have shown decreased concentrations in the last four years, comparative to historical lows in these wells. Successive years of data are needed to determine whether a decreasing trend will continue. Conversely, concentrations in MW04-12A have shown fluctuations greater than 0.2 mg/L, with a decreasing trend observed since 2011. Uranium concentrations in this well have not exceeded any guidelines since 2016. MW06-19 has shown significant fluctuations and elevated concentrations in the last four years. Concentrations in MW06-14 were originally showing a decreasing trend since sampling began, which was followed by an increasing trend from 2011 to 2015. Since 2015, MW06-14 is showing decreasing concentrations in Uranium. Trends cannot be established on these changes in concentration until successive years are evaluated. MW10-01 and MW10-02 are showing slight increasing trends but remain low in comparison the other wells.

4. CONCLUSIONS AND RECOMMENDATIONS

4.1 CONCLUSIONS The following conclusions have been drawn from the results of the 2018 Environmental Monitoring Program at the ASRDF:

1. Samples from the Leachate Pond exceeded the applicable guidelines for Ammonia, Arsenic, Boron, Chloride, Chromium, Cobalt, Colour, Conductivity, Fecal Coliforms, Lithium, Temperature (Field), Manganese, Sodium, and Vanadium. This is consistent with previous years.

2. The 2018 groundwater level measurements show that groundwater generally flows northwest and this is consistent.

3. MW10-03 has continued to identify parameters that are inconsistent with the chemistry in other monitoring wells in the program and may not accurately represent background conditions. MW10-03 is showing increasing trends of some parameters, including Conductivity, Magnesium, Sodium, Sulphate, and TDS. MW-5 has been used as a well to indicate non-influenced groundwater, but is also being re-evaluated as a background well. There have been exceedances for some leachate indicating parameters noted in MW-5 that indicate MW-5 might not be a good location for a background well. A different location for a background well will be explored in 2019.

4. Similar to the results of previous years, exceedances of the applicable BC guidelines were found in the monitoring wells near the landfill boundary.

a) Exceedances of the applicable guidelines for Ammonia, Chloride, Colour, Conductivity, Dissolved Oxygen, Fecal Coliforms, Nitrate, Sulphate, and select dissolved metals (Arsenic, Boron, Chromium, Cobalt, Iron, Lithium, Manganese, Molybdenum, Selenium, Sodium, Strontium, and Uranium) occurred in at least one monitoring well in 2018.

b) Monitoring wells MW04-12A, MW06-14, MW06-15B, MW06-16, MW06-19, and MW10-03 had the most exceedances, and generally show elevated concentrations of many parameters over the other monitoring wells.

5. Leachate-indicating parameters in the groundwater in the buffer areas of the landfill remained generally consistent with 2017 concentrations in most wells. The areas in the northwest (MW04-12A, MW06-15B, and MW06-16) and the southwest (MW06-19, MW10- 02 and MW13-01) of the ASRDF are considered to represent impacts from landfill activities, with the following highlights:

a) Dissolved metals concentrations remained elevated in the northwest down-gradient sampling locations. However, wells in the northwest buffer area showed a decrease in concentration of many parameters since 2015. Many of these parameters were

34

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

previously increasing, suggesting the groundwater in this buffer area was affected by the clay stockpile in the north corner of the site which prevented precipitation infiltration. Since the stockpile was removed in 2015, these parameters appear to be decreasing, as more precipitation is infiltrating and more flushing is occurring. These parameters include Chloride, Conductivity, Magnesium, Sodium, and Uranium. Despite decreases in the last three years, MW04-12A and MW06-16 have overall increasing trends of Boron, Sodium, and Conductivity. Further monitoring will determine whether the concentrations will continue to trend downward. MW06-15B is showing several distinct decreasing trends since 2013 or 2014, including Boron, Chloride, Conductivity, Magnesium, Sodium, and Sulphate. Increasing trends have been noted in MW06-15B in Cadmium and Selenium.

b) Wells in the southwest buffer area showed generally consistent concentrations in 2018, with decreases in some parameters. MW06-14 has shown decreasing concentrations in several parameters in the last three years, which had previously been showing increasing trends. These parameters include Conductivity, Magnesium, Sodium, Sulphate, and TDS. MW13-01 is showing decreasing trends since sampling began at this well in Cadmium, Conductivity, Selenium, Sodium, Sulphate, and Uranium. The RDNO will pay close attention to these trends in the future and continue to monitor possible impacts from irrigation of the poplar plantation in the south buffer.

c) Nitrate concentrations are elevated in sampling locations located cross-gradient from site operations (MW06-14, MW06-19, MW13-01, and MW10-02). This indicates that ammonia, which is typically high in the Leachate Pond samples, may be converted to nitrate as a product of oxidation as the groundwater meets and mixes with ambient oxygenated groundwater.

6. After the 2015 leachate outbreak and well damage, MW-12B showed significantly elevated concentrations of certain parameters. These parameters included Conductivity, Chloride, Boron, Iron, Magnesium, Manganese, Sodium, and TDS. Since 2015 these parameters have all shown significant decreases, typically returning to values seen in 2006. This is an indication that the elevated parameters seen in 2015 were a result of the leachate outbreak and damage to this well that occurred just before sampling in 2015. More years of data will help determine trends and groundwater conditions at this well.

7. Monitoring well MW13-01 was dry at the August and October sampling events in 2018.

8. MW16-01 was drilled in June 2016, approximately 80 m north of MW10-01 on the northwest edge of the site, in order to confirm groundwater flow direction and property boundary conditions. This well has exceedances in some parameters of concern including Chloride, Conductivity, Manganese, Molybdenum, Sulphate, and Uranium. Most of these parameters have been decreasing in concentration each year since installation, however, they are still exceeding applicable guidelines. Concentrations in MW16-01 are lower than up-gradient wells MW06-16, MW06-15B, and MW04-12A for most parameters. Groundwater conditions and possible trends cannot be determined until successive years

35

2018 Annual Report: Armstrong/Spallumcheen Recycling and Disposal Facility

of data are evaluated and this plume edge will continue to be assessed with respect to potential impacts on neighboring properties and changes in landfill operations.

9. VP11-14B (W) was sampled for the first time in the fall of 2016. In 2018, VP11-14B (W) was damaged and not able to be repaired. This well will no longer be sampled as part of the program.

10. Additional groundwater monitoring wells are being considered for the east and south sides of the landfill. There are no wells being sampled along Powerhouse Road nor along the south boundary of the site. One or two wells will be considered for each side.

4.2 RECOMMENDATIONS a) Continue with the currently established sampling program, and assess trends of exceedances and property boundary conditions.

b) Evaluate potential trends in 2019 for Boron, Cadmium, Chloride, Conductivity, Iron, Magnesium, Manganese, Nitrate, Selenium, Sodium, Sulphate, TDS, and Uranium.

c) Assess and report on the options for resolving leachate migration issues and leachate plume changes around the ASRDF.

Guideline Notes for Reports for RDNO Recycling and Disposal Facilities Water Quality Results

1. Notes for BC Approved Water Quality Guidelines for freshwater aquatic life (BCAWQG AL) General Notes: The Water Quality Guidelines (Criteria) Reports by BC Ministry of Environment were used as references for the guidelines. (Internet address: http://www.env.gov.bc.ca/wat/wq/wq_guidelines.html ). Overview Reports (BC MOE) were used as the references for the guidelines unless the note for specific analyte indicates that the Technical Appendix (BC MOE) was used. / For some parameters, guidelines are specified as two values: the maximum value or the acute criterion, and the 30-day average value or the chronic criterion. The maximum value was used in this report for parameters that have both guideline values. Note 1.1 for Dissolved oxygen: The instantaneous minimum guideline for dissolved oxygen is 5 mg/L for all life stages other than buried embryo/alevin. The instantaneous minimum guideline for dissolved oxygen in the water column is 9 mg/L for buried embryo/alevin. The instantaneous minimum guideline for dissolved oxygen in interstitial water is 6 mg/L for buried embryo/alevin. The 30-day mean guideline (minimum) for dissolved oxygen is 8 mg/L for all life stages other than buried embryo/alevin. The 30-day mean guideline (minimum) for dissolved oxygen in the water column is 11 mg/L for buried embryo/alevin. The 30-day mean guideline (minimum) for dissolved oxygen in interstitial water is 8 mg/L for buried embryo/alevin. Note 1.2 for pH: pH less than 6.5: No statistically significant decrease in pH from background. pH from 6.5 to 9.0: Unrestricted change permitted within this range. pH over 9.0: No statistically significant increase in pH from background. See BC MOE Overview Report for additional details. Note 1.3 for Temperature: The maximum daily temperature of 19 degrees Celsius is for streams with unknown fish distribution. See BC MOE Overview Report for additional details for streams with unknown fish distribution, and specific guidelines for streams with known fish distribution, and guideline for lakes and impoundments. Note 1.4 for Chloride: To protect freshwater aquatic life from acute and lethal effects, the maximum concentration of chloride (mg/L as NaCl) at any time should not exceed 600 mg/L. To protect freshwater aquatic life from chronic effects, the average (arithmetic mean computed from five weekly samples collected over a 30-day period) concentration of chloride (mg/L as NaCl) should not exceed 150 mg/L. Note 1.5 for Colour: 30-day average true colour of filtered water samples shall not exceed background levels by more than 5 colour units in clearwater systems or 20% in coloured systems. See BC MOE Overview Report for additional details. Note 1.6 for Fluoride: Correction by BC MOE Sept. 2011: The criteria for Fluoride (total) in mg/L is 0.4 as a maximum where the water hardness (as CaCO3) is less than or equal to 10 mg/L. Otherwise use the equation: LC50 fluoride = -51.73 + 92.57 log10 (Hardness) and multiply by 0.01. Hardness is as CaCO3 in units mg/L. Note 1.7 for pH: pH less than 6.5: No statistically significant decrease in pH from background. pH from 6.5 to 9.0: Unrestricted change permitted within this range. pH over 9.0: No statistically significant increase in pH from background. See BC MOE Overview Report for additional details. Note 1.8 for Sulphate:

2016-2018_ASRDF_Results Guideline Notes Page 108 of 131 Armstrong/ Spallumcheen Recycling and Disposal Facility Water Quality Results

The approved 30-day average (minimum of 5 evenly-spaced samples collected in 30 days) water quality guidelines to protect aquatic life in BC for sulphate are: 128 mg/L at hardness of 0 to 30 mg/L as CaCO3 218 mg/L at hardness of 31 to 75 mg/L as CaCO3 309 mg/L at hardness of 76 to 180mg/L as CaCO3 429 mg/L at hardness 181 to 250 mg/L as CaCO3 Need to determine guideline based on site water for hardness greater than 250 mg/L as CaCO3. For screening purposes in this report, exceedance were flagged for sulphate greater than 429 mg/L at hardness greater than 250 mg/L as CaCO3. Note 1.9 for Total suspended solids: Maximum Induced Suspended Sediments - mg/L or % of background: - 25 mg/L in 24 hours when background is less than or equal to 25; - Mean of 5 mg/L in 30 days when background is less than or equal to 25; - 25 mg/L when background is between 25 and 250; - 10% when background is greater than or equal to 250. / There are no Recycling and Disposal Facilities where up-gradient and down-gradient samples have been collected in one water body; therefore this guideline does not apply to any of RDNO's Recycling and Disposal Facility sites. Note 1.10 for Turbidity: When background is less than or equal to 8 NTU: - Maximum Induced Turbidity of 8 NTU in 24 hours. - For sediment inputs that last between 24 hours and 30 days (daily sampling preferred) the mean turbidity should not exceed background by more than 2 NTU. Maximum Induced Turbidity of 5 NTU when background is between 8 and 50 NTU. Maximum Induced Turbidity of 10% when background is greater than 50 NTU. / There are no Recycling and Disposal Facilities where up-gradient and down-gradient samples have been collected in one water body; therefore this guideline does not apply to any of RDNO's Recycling and Disposal Facility sites. Note 1.11 for Aluminum (dissolved): The maximum concentration of dissolved aluminum at any time should not exceed: 1. 0.10 mg/L when the pH is greater than or equal to 6.5 2. The value (in mg/L) determined by the following relationship if pH less than 6.5 Dissolved Aluminum = e (1.209-2.426 (pH) + 0.286 (pH)²) The 30-day average concentration of dissolved aluminum (based on a minimum of 5 approximately weekly samples) should not exceed: 1. 0.05 mg/L when the median pH over 30 days is greater than or equal to 6.5 2. the value determined by the following relationship at median pH less than 6.5 Dissolved Aluminum = e (1.6-3.327 (median pH) + 0.402 (median pH)²) Note 1.12 for Arsenic (dissolved): The recommended guideline is for total arsenic. Note 1.13 for Boron (dissolved): The recommended guideline is for total boron. Note 1.14 for Cadmium (dissolved):

2016-2018_ASRDF_Results Guideline Notes Page 109 of 131 Armstrong/ Spallumcheen Recycling and Disposal Facility Water Quality Results

The guideline for cadmium is determined on a site-specific basis according to the local water hardness. The guideline for cadmium (dissolved) in μg/L is determined by the following equations for short term exposure: 1. If hardness (as CaCO3) is less than 7 mg/L then maximum is 0.0380 μg/L 2. If hardness (as CaCO3) is from 7 to 45 mg/L then maximum is based on equation: e to the power of {1.03[ln(hardness)] - 5.274} 3. If hardness (as CaCO3) is greater than 455 mg/L then maximum is 2.8 μg/L. When water hardness is greater than the upper bound (i.e., highest water hardness tested), a site-specific assessment may be required.

Test Method References: ALS Test Code Matrix Test Description Method Reference**

ALK-TITR-VA Water Alkalinity Species by Titration APHA 2320 Alkalinity This analysis is carried out using procedures adapted from APHA Method 2320 "Alkalinity". Total alkalinity is determined by potentiometric titration to a pH 4.5 endpoint. Bicarbonate, carbonate and hydroxide alkalinity are calculated from phenolphthalein alkalinity and total alkalinity values. CL-IC-N-VA Water Chloride in Water by IC EPA 300.1 (mod) Inorganic anions are analyzed by Ion Chromatography with conductivity and/or UV detection.

COD-COL-VA Water Chemical Oxygen Demand by Colorimetric APHA 5220 D. CHEMICAL OXYGEN DEMAND This analysis is carried out using procedures adapted from APHA Method 5220 "Chemical Oxygen Demand (COD)". Chemical oxygen demand is determined using the closed reflux colourimetric method. COLOUR-TRUE-VA Water Colour (True) by Spectrometer BCMOE Colour Single Wavelength This analysis is carried out using procedures adapted from British Columbia Environmental Manual "Colour- Single Wavelength." Colour (True Colour) is determined by filtering a sample through a 0.45 micron membrane filter followed by analysis of the filtrate using the platinum-cobalt colourimetric method. Colour measurements can be highly pH dependent, and apply to the pH of the sample as received (at time of testing), without pH adjustment. Concurrent measurement of sample pH is recommended. EC-PCT-VA Water Conductivity (Automated) APHA 2510 Auto. Conduc. This analysis is carried out using procedures adapted from APHA Method 2510 "Conductivity". Conductivity is determined using a conductivity electrode. EC-SCREEN-VA Water Conductivity Screen (Internal Use Only) APHA 2510 Qualitative analysis of conductivity where required during preparation of other tests - e.g. TDS, metals, etc.

F-IC-N-VA Water Fluoride in Water by IC EPA 300.1 (mod) Inorganic anions are analyzed by Ion Chromatography with conductivity and/or UV detection.

FCOLI-MF-ENV-VA Water Fecal coliform by membrane filtration APHA METHOD 9222 This analysis is carried out using procedures adapted from APHA Method 9222 "Membrane Filter Technique for Members of the Coliform Group". Coliform bacteria is enumerated by culturing and colony counting. A known sample volume is filtered through a 0.45 micron membrane filter. The test involves an initial 24 hour incubation of the filter with the appropriate growth medium, positive results require further testing (up to an additional 48 hours) to confirm and quantify the total coliform. This method is used for non-turbid water with a low background bacteria level. HARDNESS-CALC-VA Water Hardness APHA 2340B Hardness (also known as Total Hardness) is calculated from the sum of Calcium and Magnesium concentrations, expressed in CaCO3 equivalents.

B Method Blank exceeds ALS DQO. Associated sample results which are < Limit of Reporting or > 5 times blank level are considered reliable. DLA Detection Limit adjusted for required dilution DLDS Detection Limit Raised: Dilution required due to high Dissolved Solids / Electrical Conductivity. DLM Detection Limit Adjusted due to sample matrix effects (e.g. chemical interference, colour, turbidity). HTC Hardness was calculated from Total Ca and/or Mg concentrations and may be biased high (dissolved Ca/Mg results unavailable). MS-B Matrix Spike recovery could not be accurately calculated due to high analyte background in sample. SURR-ND Surrogate recovery marginally exceeded ALS DQO.

VOC7/VOC-SURR-MS-VA Water VOC7 and/or VOC Surrogates for Waters EPA 5035A/5021A/8260C VPH-CALC-VA Water VPH is VH minus select aromatics BC MOE VPH VPHw measures Volatile Petroleum Hydrocarbons in water. Results are calculated by subtraction of specific Monocyclic Aromatic Hydrocarbons from VH6-10, as per the BC Lab Manual VPH calculation procedure. VPHw = VH6-10 minus Benzene, Toluene, Ethylbenzene, Xylenes, and Styrene XYLENES-CALC-VA Water Sum of Xylene Isomer Concentrations CALCULATION Calculation of Total Xylenes

Total Xylenes is the sum of the concentrations of the ortho, meta, and para Xylene isomers. Results below detection limit (DL) are treated as zero. The DL for Total Xylenes is set to a value no less than the square root of the sum of the squares of the DLs of the individual Xylenes.

Qualifiers for Individual Parameters Listed: Qualifier Description

DLA Detection Limit adjusted for required dilution DLDS Detection Limit Raised: Dilution required due to high Dissolved Solids / Electrical Conductivity. DLM Detection Limit Adjusted due to sample matrix effects (e.g. chemical interference, colour, turbidity). HTC Hardness was calculated from Total Ca and/or Mg concentrations and may be biased high (dissolved Ca/Mg results unavailable). HTD Hold time exceeded for re-analysis or dilution, but initial testing was conducted within hold time. MES Data Quality Objective was marginally exceeded (by < 10% absolute) for < 10% of analytes in a Multi-Element Scan / Multi-Parameter Scan (considered acceptable as per OMOE & CCME). MS-B Matrix Spike recovery could not be accurately calculated due to high analyte background in sample.

ALK-TITR-VA Water Alkalinity Species by Titration APHA 2320 Alkalinity This analysis is carried out using procedures adapted from APHA Method 2320 "Alkalinity". Total alkalinity is determined by potentiometric titration to a pH 4.5 endpoint. Bicarbonate, carbonate and hydroxide alkalinity are calculated from phenolphthalein alkalinity and total alkalinity values. CL-IC-N-VA Water Chloride in Water by IC EPA 300.1 (mod) Inorganic anions are analyzed by Ion Chromatography with conductivity and/or UV detection.

COD-COL-VA Water Chemical Oxygen Demand by Colorimetric APHA 5220 D. CHEMICAL OXYGEN DEMAND This analysis is carried out using procedures adapted from APHA Method 5220 "Chemical Oxygen Demand (COD)". Chemical oxygen demand is determined using the closed reflux colourimetric method. COLOUR-TRUE-VA Water Colour (True) by Spectrometer BCMOE Colour Single Wavelength This analysis is carried out using procedures adapted from British Columbia Environmental Manual "Colour- Single Wavelength."

1. INTRODUCTION

This report contains the results of soil monitoring conducted during 2018 at the harvested hybrid poplar plantation, and the new hybrid poplar plantation established in 2017 at the Armstrong/Spallumcheen Recycling and Disposal Facility (ASRDF).

The harvested plantation was decommissioned in early 2017. This plantation was irrigated with leachate from the ASRDF from establishment in 2005, until the fall of 2016. The trees were harvested in early 2017, and will not be replanted. This report refers to this plantation as the “harvested plantation”, and discusses the condition of the soil after a full two years without leachate irrigation.

A new poplar plantation was planted in a different location at the ASRDF in early 2017. The new plantation is approximately 7,500 m2 in size compared to the harvested plantation which was approximately 5,000 m2 in size. The new plantation began to be irrigated with leachate in May of 2017. This report discusses the condition of the soil before leachate irrigation and the observed impacts of leachate irrigation on the soil during the 2018 growing season.

During irrigation operation, the site was irrigated with low flow emitters that covered an estimated 30% of the surface area of the plantation. The remaining area did not receive any irrigation. Thus, the leachate impacted only the irrigated 30% of the top soil on the site.

The new poplar plantation was irrigated with 368,000 U.S. gallons (1,393,032 litres) of leachate during 2018. The site was irrigated with leachate and fresh water for 120 days from May to September in 2018.

The 2018 soil assessment program at the new plantation included the following: soil sampling twice during the year (in April before system start up and in October following system shut down) with a number of analysis conducted at the laboratory, including Sodium Adsorption Ratio (SAR) tests. The harvested plantation site soil was sampled once during the year, in October, following the same sampling protocol and laboratory analysis as the soil samples from the new plantation.

This report discusses the detailed results of the soil analysis for the harvested plantation and the new plantation separately. See section 2 for the harvested plantation results and section 3 for the new plantation results. In fall 2018, after two years without leachate irrigation, the soil at the harvested plantation site has shown significant soil quality improvements, including healthy decreases in SAR, conductivity, chloride, sodium, sulphur, and boron concentrations. The soil at this harvested site will no longer be sampled yearly, as it has been determined that the soil is in good condition. The site will continue to be flushed naturally and cleaned through phytoremediation by the vegetation growing at this site. As expected, the soil at the new plantation sampling showed some increases in the concentration of chloride, sodium, SAR, and conductivity in the irrigated area after the first season of leachate irrigation. The results of the fall 2018 sampling, after the second season of leachate irrigation, showed an improvement in the soil nutrient levels and quality in the irrigated surface soil. This included a decrease in SAR, conductivity, chloride, and sodium from the 2017 values. However, these parameters increased in concentration in the subsurface soil depths, indicating they are being leached through the soil column.

1.1. SAMPLING METHODOLOGY

The 2018 monitoring program focused on soil nutrient and quality assessment and consisted of a visual assessment of the soil surface and collection of soil samples. The harvested plantation was sampled once in the fall of 2018, after having no irrigation applied for two full years. This sampling occurred on October 4, 2018. The new plantation site was sampled twice during 2018. The first sampling occurred on April 26, 2018, before irrigation began for the season. The second sampling occurred on October 4, 2018, after irrigation had stopped for the season.

During each sampling event, six composite samples were taken from either site. Three composite soil samples were collected from the irrigated area of the site; one from the 0-15 cm depth in the soil (eight subsamples), one from the 15-45 cm depth in the soil (four subsamples), and one from the 45-90 cm depth in the soil (four subsamples). Samples were collected from within the spray area of the irrigation emitters (within 1 m of the tree stems) to ensure that soil samples were representative of the soil conditions in the irrigated area. The other three composite soil samples were collected from the non-irrigated area of the site, one from the 0-15 cm depth in the soil (eight subsamples), one from the 15-45 cm depth in the soil (four subsamples), and one from the 45-90 cm depth in the soil (four subsamples). These samples were collected from the area between the rows of trees and well away from the area reached by the irrigation system.

Soil samples were analyzed for macro and micro nutrients, CSR trace elements, and quality parameters. All samples were submitted to ALS Laboratories in Burnaby, BC and Saskatoon, SK for analysis. Previously, Exova Laboratories was used for soil analysis from 2005 to 2012, and AGAT Laboratories was used for soil analysis from 2013 to 2017.

2. HARVESTED PLANTATION MONITORING RESULTS

The observed soil quality in 2018 at the harvested plantation site has improved significantly, after two years without leachate irrigation. Past elevated parameters have shown drastic decreases, typically returning to close to pre-leachate values. Some of these parameters include SAR, conductivity, sodium, boron, chloride, and sulphur. The proportions of the cations calcium, magnesium, and sodium appear to be adjusting closer to the ratio observed before leachate irrigation as well. Each of these parameters, and more, are discussed in depth in the following sections.

2.1. VISUAL ASSESSMENT OF SITE AND TREES After the plantation was harvested in early 2017, the tree stumps have grown multiple healthy shoots. In 2018 the site was left to grow naturally. The harvested site will be cut back and maintained in 2019.

2.2. SOIL ASSESSMENT

Tables 1-5 contain the soil analytical data for the harvested plantation from 2018 as follows:

• Table 1 contains surface soil (0-15 cm depth) nutrient and quality data from samples collected in October 2018 from the past-irrigated and unirrigated areas of the site, and for comparison the same data set from May 2005 before leachate irrigation began • Table 2 contains historical and 2018 fall surface soil (0-15 cm depth) nutrient and quality data from the past-irrigated areas of the site • Table 3 contains historical and 2018 soil nutrient and quality data from the subsurface soil samples (15-45 cm depth) of the past-irrigated areas of the site • Table 4 contains 2016, 2017, and 2018 nutrient and quality data from the irrigated and unirrigated deep soil (15-45 cm and 45-90 cm depth) • Table 5 contains historical and 2018 trace element data from surface soil (0-15 cm depth) of the past-irrigated areas of the site

SOIL MACRONUTRIENTS

The soil macronutrients nitrate, phosphorus, and potassium were measured in both the past- irrigated and unirrigated areas of the site in fall 2018. Table 1 contains the collected surface soil macronutrient data from 2018 and from May 2005, prior to leachate irrigation starting. Table 2 contains the historical irrigated surface soil data for these nutrients. Table 3 contains the historical nitrate data for the 15-45 cm depth irrigated area, and table 4 contains the collected nitrate data from the 15-45 cm and 45-90 cm depths in 2018, 2017, and 2016 for comparison.

Plant-available nitrogen (nitrate) The concentration of plant-available nitrogen (measured as nitrate) fluctuated throughout the twelve years of leachate irrigation in each season and from year to year. In 2018, the nitrate concentration decreased in the surface soil and subsurface soils in the past-irrigated area and unirrigated area. The nitrate concentrations are lower than typical which may be caused by the new shoots taking up more nitrate in 2018 than they did in 2017, when the site was first harvested.

Phosphorus In 2018, both the past-irrigated and unirrigated area showed a decrease in plant-available phosphorus from 2017. The 2018 phosphorus concentrations are similar to the pre-leachate concentrations. This value is within the optimum range for tree growth.

Potassium The concentration of plant-available potassium in the soil fluctuated from year to year during the twelve years of leachate irrigation. In 2018, the potassium value showed a decrease in the past- irrigated area and unirrigated area from 2017. The potassium value observed in the past-irrigated area in 2018 is much closer to the pre-leachate value. The soil level remains within the healthy range for tree growth.

SOIL SECONDARY MACRONUTRIENTS

The soil secondary macronutrients calcium, magnesium, sodium, and sulphur were measured in both the past-irrigated and unirrigated areas of the site in fall 2018. Table 1 contains the collected surface soil macronutrient data from 2018 and from May 2005, prior to leachate irrigation starting. Table 2 contains the historical irrigated surface soil data for these nutrients. Table 3 contains the historical sulphur data for the 15-45 cm depth irrigated area, and table 4 contains the collected sulphur data from the 15-45 cm and 45-90 cm depths in 2018, 2017, and 2016 for comparison.

Calcium In the irrigated areas of the site, the soil concentration of calcium declined dramatically during the first few years of leachate irrigation and had remained around 60% of the pre-leachate level since. The calcium concentration in September 2016 was the lowest it had been since irrigation began, at about 30% of the pre-leachate level. In 2017, after a year without leachate irrigation, the calcium concentration increased to almost 80% of the pre-leachate value. However, in 2018, the calcium concentration decreased in the past-irrigated and unirrigated area. The 2018 calcium value is still within the normal soil range.

Magnesium The soil concentrations of magnesium in the irrigated area of the site rose significantly in the first couple of years of leachate irrigation and then remained fairly stable at this elevated level. In 2018, after two years without leachate irrigation, the magnesium concentration has decreased to closer to the pre-leachate value.

Sodium In the irrigated areas of the site, the sodium concentration of the soil increased dramatically in the first couple of years of leachate irrigation and had remained elevated since. Sodium concentrations reached a historical maximum in 2016. In 2017 the sodium concentration decreased over 70%, and in 2018, after two years without leachate irrigation, the sodium concentration has decreased even further to within 20 mg/kg of the pre-leachate value..

Sulphur The concentration of sulphur (measured as the plant-available form sulphate) rose significantly in the irrigated area of the site in the first few years of leachate irrigation and had remained fairly elevated since, reaching up to 125 mg/kg in the surface soil, compared to a pre-leachate concentration of 6.0 mg/kg. In 2017 the sulphur concentration decreased significantly, and in 2018, after two years without leachate irrigation, the sulphur concentration has decreased further to <8.0 mg/kg in the surface soil. Sulphate values are now within a few mg/kg of the pre-leachate concentration at all depths.

There was a gradual change in the proportions of calcium, magnesium, and sodium in the soil at this site during leachate irrigation. Calcium concentrations in the soil gradually decreased, while magnesium and sodium concentrations gradually increased. These three parameters are all cations and occupy the same sites on soil exchange sites. It appeared that the relatively high concentration of magnesium in the leachate was slowly favoring magnesium on soil exchange sites over calcium. The amount of sodium on the exchange sites was much higher than pre- leachate and in non-irrigated areas of the site, due to the amount of sodium in the leachate. Now

that there has been no leachate irrigation for two years, the proportions of these cations appear to be adjusting closer to the ratio observed before leachate irrigation.

SOIL MICRONUTRIENTS

The soil micronutrients iron, copper, zinc, boron, manganese and chloride were measured in both the past-irrigated and unirrigated areas of the site in fall 2018. Table 1 contains the collected surface soil micronutrient data from 2018 and from May 2005, prior to leachate irrigation starting. Table 2 contains the historical irrigated surface soil data for these nutrients. Table 3 contains the historical chloride data for the 15-45 cm depth irrigated area, and table 4 contains the collected chloride data from the 15-45 cm and 45-90 cm depths in 2018, 2017, and 2016 for comparison.

Copper, zinc, iron The soil concentrations of plant-available copper, iron and zinc in the leachate-irrigated areas of the site fluctuated slightly since leachate irrigation began on the site but did not change significantly from levels observed in the non-irrigated areas of the site, and as measured at the site prior to the beginning of leachate irrigation. In 2018, two years after leachate irrigation stopped, there were no significant changes in the concentrations of these nutrients. The concentrations of these soil micronutrients are considered to be in the normal range and are not of concern.

Manganese The soil concentration of manganese fluctuated from year to year during leachate irrigation, with a couple of years showing elevated concentrations. In 2018, the manganese concentrations in both areas of the old plantation increased slightly, remaining at a similar value as was seen before leachate irrigation.

Boron The soil concentration of boron increased significantly after leachate irrigation began and fluctuated from year to year. In fall of 2016, boron concentration in the soil was the highest recorded, at 9.7 mg/kg in the irrigated area. In 2018, after two years without leachate irrigation, the boron has decreased to 2.87 mg/kg in the irrigated area. The boron concentration in the unirrigated area was 1.82 mg/kg in 2018 which is similar to the value seen in 2017. The boron present in the irrigated area of the site is no longer above the concentration that is considered toxic to sensitive species (>3 mg/kg).

Chloride The soil concentration of chloride increased significantly after leachate irrigation began and remained elevated compared to the pre-leachate level at this plantation. Chloride concentrations are subject to winter flushing, and typically returned to pre-leachate values at the spring sampling events. The highest concentrations at all soil depths of the irrigated area were observed in the fall of 2016, reaching up to 811 mg/kg in the deep soil and 432 mg/kg in the surface soil. In the fall of 2018, the chloride had experienced considerable flushing and decreased to 10 mg/kg in the deep soil, and 13 mg/kg in the surface soil. The pre-leachate irrigation value in 2005 was 10.6 mg/kg, therefore, it appears the excess chloride from the leachate has been flushed.

SOIL QUALITY PARAMETERS

Soil quality parameters pH, electrical conductivity, and SAR were measured in both the past- irrigated and unirrigated areas of the site in fall 2018. Table 1 contains the collected surface soil quality data from 2018 and from May 2005, prior to leachate irrigation starting. Table 2 contains the historical irrigated surface soil data for these parameters. Table 3 contains the historical quality data for the 15-45 cm depth irrigated area, and table 4 contains the collected quality data from the 15-45 cm and 45-90 cm depths in 2018, 2017, and 2016 for comparison.

Soil pH Soil pH in the irrigated area of the site had been impacted by the relatively high pH of the leachate, typically showing values above 8.0 and reaching up to 9.1 in the surface soil, compared to the pre-leachate value of 7.4. In 2018, the soil pH has decreased again in the irrigated surface area to 7.74, which is closer to the pre-leachate value. Most of the deep samples (>15 cm) saw an increase in pH from 2017, which may be caused by the natural flushing occurring. The soil pH level at depth is still within the healthy range, and is not greater than the values observed at this site in the past.

Soil electrical conductivity or salinity Historically, the soil conductivity of the leachate-irrigated areas of the site was elevated during the leachate-irrigation season, then returned to near pre-leachate levels the following spring after the leachate constituents that increase conductivity (sulphate, sodium) leached from the soil with rain and snowmelt. In 2016, fall samples in all depths of the irrigated area had a higher soil conductivity than had been previously recorded. However, in the fall of 2017, after a year without leachate, the soil conductivity decreased significantly in all depths of the irrigated and unirrigated area. In 2018, the conductivity further decreased at all depths of both areas of the site. The decrease in conductivity was greatest at the surface soil depths in 2018, with the conductivity decreasing from 1.48 dS/m to 0.595 dS/m in the surface irrigated area. The 2018 conductivity values are comparable to the pre-leachate value of 0.52 dS/m.

Soil sodium absorption ratio (SAR) SAR analysis has been done on shallow and deep samples in spring and fall since 2014 to assess the impact of sodium from the leachate on the soil permeability. The SAR analysis is done on a saturated paste extract of soil and is the ratio of the amount of soluble sodium to calcium plus magnesium in the soil. SAR is an assessment of whether the presence of sodium in the soil is negatively impacting soil structure and permeability. The sodium content of the surface soil rose very quickly following the start of leachate irrigation at this plantation from a pre-irrigation level of 31 mg/kg in spring 2005, to 322 mg/kg in fall 2006. After fall 2006, the sodium level fluctuated between 260 and 657 mg/kg. Therefore, SAR analysis was added in 2014 to determine the effect of this elevated sodium.

A SAR value of <2.1 indicates that there is no risk of sodium permeability hazard in the soil. A SAR of 2.1 to 12 indicates increasing risk, and a SAR above 12 indicates that the soil is ‘sodic’ and that there is a high risk of sodium-induced damage to soil structure.

After SAR analysis began in 2014, the SAR increased each successive year in the irrigated areas of site. However, in 2017, after a year without leachate irrigation, the SAR decreased dramatically

at all depths of the past-irrigated area. In 2018, the SAR decreased in the surface soil of the irrigated area to 0.45. This is a significant decrease from 2.47 in 2017 and 8.9 in 2016. The subsurface samples saw large decreases in 2017, however in 2018, the SAR level increased slightly at all subsurface depths. The SAR values at subsurface are still well below the values seen in the past at this site, but most are still slightly above the no risk value of 2.1.

The SAR levels in the unirrigated area had always been less elevated and were very low in the surface soil, but were showing increasing levels in the subsurface and deep soil, indicating that the sodium had migrated throughout the site at depth. In 2017, all depths of the unirrigated area showed decreased SAR values. In 2018, the unirrigated area samples showed slightly increased SAR values. However, only the deepest unirrigated soil depth had a SAR value above the no risk value. Although we do not have the pre-leachate value of SAR to compare to, it is evident that the SAR levels have decreased significantly and are now well below the high-risk “sodic” level or below the no-risk level.

SOIL TRACE ELEMENT STATUS

Contaminated Sites Regulation (CSR) trace elements were assessed in the soil of both the past- irrigated and unirrigated areas of the site in 2018. Table 5 contains the historical trace element data and the 2018 values.

Over the twelve years of leachate irrigation, there were no measurable changes in the soil concentration of trace elements in either the irrigated or unirrigated soil. None of the eleven CSR- regulated trace elements were found in concentrations markedly higher than observed in the unirrigated area or as observed before leachate irrigation. There was not expected to be a significant change in the soil trace elements as the leachate itself contains low levels of trace elements. The 2018 results are very similar to historical concentrations, with most elements decreasing slightly. Variability between 2017 and 2018 data may also be a result of the change in laboratories.

3. NEW PLANTATION MONITORING RESULTS

During the 2018 irrigation season, a total of 368,000 U.S. gallons of landfill leachate was irrigated onto the new poplar plantation.

In the fall of 2018, the observed soil quality at the new leachate irrigation plantation saw an increase in concentration in some parameters in the subsurface irrigated area from the 2017 values. These parameters include chloride, sodium, sulphur, SAR and conductivity. These parameters are elevated in the leachate, and therefore were expected to increase in the soil after irrigation began. In 2018, the irrigated surface soil saw some nutrient and quality improvements

from the 2017 values, including a decrease in SAR, chloride, and sodium. Each of these parameters, and more, are discussed in more depth in the following sections.

3.1. VISUAL ASSESSMENT OF SITE AND TREES

The new plantation was established in early 2017 and covers an area of approximately 7,500 m2. The hybrid poplar trees were planted in May 2017 in 18 rows of 26 trees. The trees looked healthy at the time of the site visits in 2018. There were some unhealthy trees in the south-west corner. The reason for this is unknown at this time, but may have to do with the starting soil condition in this corner of the site. The soil was sampled in this area separately to assess soil quality and no noticeable issues were discovered. The new plantation varies in soil texture and particle size throughout the site. Approximately 50% of the plantation is a loamy soil, 30% is a sandy soil, and 20% is a gravel soil. Representative subsamples were taken in each soil type. During the spring of 2018, the north-east corner of the site experienced some flooding. During the summer, there was a period of drought. Weed control on the site during the 2018 season was excellent. The surface of the soil appeared normal. There was no evidence of surface erosion or runoff from irrigation.

3.2. SOIL ASSESSMENT

Tables 6-10 contain the soil analytical data from 2018 as follows:

• Table 6 contains surface soil (0-15 cm depth) nutrient and quality data from samples collected in May 2018 and October 2018 from the irrigated and unirrigated areas of the site, and for comparison the same data set from May 2017 before leachate irrigation began. • Table 7 contains historical and 2018 fall surface soil (0-15 cm depth) nutrient and quality data from the irrigated areas of the site • Table 8 contains surface soil (0-15 cm) nutrient and quality data from the irrigated area in the fall of 2017, to the spring of 2018 to display overwinter flushing. • Table 9 contains historical and 2018 soil nutrient and quality data from the subsurface soil samples (15-45 cm depth) of the irrigated area of the site • Table 10 contains 2018 irrigated and unirrigated deep soil sample results (45-90 cm depth) • Table 11 contains historical and 2018 trace element data from surface soil (0-15 cm depth) of the irrigated and unirrigated areas of the site

SOIL MACRONUTRIENTS

The soil macronutrients nitrate, phosphorus, and potassium were measured in both irrigated and unirrigated areas of the site in spring and fall 2018. Table 6 contains the collected surface soil macronutrient data from October 2018 and from May 2017, prior to leachate irrigation. Table 7 contains the historical irrigated surface soil data for these nutrients. Table 9 contains the historical nitrate data for the 15-45 cm depth irrigated area, and Table 10 contains the collected nitrate data from the 15-45 cm and 45-90 cm depths in 2018.

Plant-available nitrogen (nitrate) The pre-leachate surface soil sampled in May 2017 had a nitrate concentration of 9.0 mg/kg in the irrigated area. In 2018, after two seasons of leachate irrigation, the irrigated and unirrigated area had nitrate concentrations of 20.6 mg/kg and 10.5 mg/kg, respectively. These values are an increase from 2017. This increase is considered a positive effect because the nitrate levels observed in 2017 were slightly low for tree growth. High levels of nitrate are not expected as fertilizer is not added to the soil. Nitrate levels may change in the future as more leaves and other organic matter becomes available for the trees.

Phosphorus The pre-leachate plant-available phosphorus concentrations were both 36.0 mg/kg in the irrigated and unirrigated areas of the plantation. In 2018, the phosphorus concentrations were very similar to this pre-leachate value, at 38 mg/kg in the irrigated surface soil and 35 mg/kg in the unirrigated surface soil. The soil phosphorus level is within the optimum range for tree growth.

Potassium The concentration of plant-available potassium was 178 mg/kg in irrigated area before leachate irrigation began. In 2018, the potassium increased to 373 mg/kg in the irrigated area and to 218 mg/kg in the unirrigated area. This concentration of potassium is considered in excess but does not have a negative impact on the tree growth.

SOIL SECONDARY MACRONUTRIENTS

The soil secondary macronutrients calcium, magnesium, sodium, and sulphur were measured in both irrigated and unirrigated areas of the site in spring and fall of 2018. Table 6 contains the collected surface soil macronutrient data from fall 2018 and from May 2017, prior to leachate irrigation. Table 7 contains the historical irrigated surface soil data for these nutrients. Table 9 contains the historical sulphur data for the 15-45 cm depth irrigated area, and table 10 contains the collected sulphur data from the 15-45 cm and 45-90 cm depths in 2018.

Calcium The pre-leachate calcium concentration in the irrigated area was 1990 mg/kg. In 2018, after two seasons of leachate irrigation, the calcium concentration decreased to 1090 mg/kg in the irrigated area, and to 1750 mg/kg in the unirrigated area. A decrease in calcium concentrations also occurred in the irrigated area at the old plantation after leachate irrigation startup. The calcium concentration is within the normal range for tree growth.

Magnesium In 2018, the irrigated area had a large increase in magnesium concentration from 99 mg/kg before leachate to 624 mg/kg after two seasons of leachate irrigation. An increase in magnesium in the irrigated area was also seen in the old plantation after leachate irrigation startup. The magnesium concentration is considered within the normal range for tree growth.

Sodium The surface soil in the irrigated area showed a significant increase in sodium concentration from the pre-leachate concentration of 17 mg/kg to the post-leachate irrigation concentration of 464

mg/kg in the fall of 2017. In 2018, the sodium concentration decreased slightly to 338 mg/kg. The unirrigated area remained low at <50 mg/kg. An increase in sodium is typical of the irrigated area, as the leachate has a relatively high concentration of sodium.

Sulphur In the fall of 2018, after two seasons of leachate irrigation, the irrigated area of the plantation had a sulphate concentration of 15.5 mg/kg. This is a decrease from the fall of 2017, which had a sulphate concentration of 60 mg/kg. The unirrigated area remained at a similar, low value. An increase in sulphur in the irrigated area was also seen at the old plantation after leachate irrigation startup. The pre-leachate sulphate concentration measured was considered low for crop growth. In fall of 2018, the irrigated surface soil was within the desirable sulphur range.

Increases in sodium and sulphur concentrations observed at the site appear to be transitory; overwinter soil flushing removes most of the sodium and sulphur added in leachate. Soil sodium was measured as 464 mg/kg in the fall of 2017 and decreased to 136 mg/kg in the spring of 2018 after winter flushing. Likewise, sulphate was measured as 60 mg/kg in the fall of 2017 and decreased to 6 mg/kg in the spring of 2018 after winter flushing.

SOIL MICRONUTRIENTS

The soil micronutrients iron, copper, zinc, boron, manganese and chloride were measured in both irrigated and unirrigated areas of the site in spring and fall 2018. Table 6 contains the collected surface soil micronutrient data from fall 2018 and from May 2017, prior to leachate irrigation. Table 7 contains the historical irrigated surface soil data for these nutrients. Table 9 contains the historical chloride data for the 15-45 cm depth irrigated area, and table 10 contains the collected chloride data from the 15-45 cm and 45-90 cm depths in 2018.

Copper, zinc, iron The soil concentrations of plant-available copper and zinc had no significant change in the fall sampling, over the pre-leachate sampling in the spring. The fall iron concentrations increased from 2017 and from the pre-leachate concentration in the irrigated surface soil. The concentrations of these soil micronutrients are considered to be in the normal range at this time.

Manganese The soil concentration of manganese in the irrigated and unirrigated areas in the fall of 2018 both decreased slightly but remained similar to the concentrations seen prior to leachate irrigation startup and in the fall of 2017. The manganese concentration is considered to be within the desirable range for plant growth.

Boron In 2018, the boron concentration in the irrigated area increased to 7.9 mg/kg from 2.3 mg/kg in 2017. The boron concentration in the unirrigated area remained the same. The irrigated soil has increased above the boron concentration considered toxic to sensitive species (>3.0 mg/kg). This increase in boron was expected and occurred at the harvested plantation as well.

Chloride The surface soil in the irrigated area showed a significant increase in chloride concentration from the pre-leachate concentration in the fall of 2017 after one season of leachate irrigation. The increase in chloride was from 4.0 mg/kg to 496 mg/kg. In 2018, after two seasons of leachate irrigation, the chloride concentration decreased significantly to 33.9 mg/kg in the irrigated area. The significant decrease may have been caused by recent rainfall just before the October sampling event, which could have leached some chloride from the surface soil. The unirrigated area remained similar to the chloride concentration observed in 2017 in this area. An increase in chloride concentration was seen at most of the subsurface samples, suggesting that the chloride is leaching below the surface soil. An increase in chloride is typical of the irrigated area, as the leachate has a relatively high concentration of chloride itself. There is considerable flushing of chloride from the soil over winter, decreasing from 496 mg/kg in the fall of 2017 to 1.3 mg/kg in the spring of 2018 in the irrigated surface soil.

SOIL QUALITY PARAMETERS

Soil quality parameters pH, electrical conductivity, and SAR were measured in both the past- irrigated and unirrigated areas of the site in spring and fall of 2018. Table 6 contains the collected surface soil quality data from fall 2018 and from May 2017, prior to leachate irrigation starting. Table 7 contains the historical irrigated surface soil data for these nutrients. Table 9 contains the historical quality data for the 15-45 cm depth irrigated area, and table 10 contains the collected quality data from the 15-45 cm and 45-90 cm depths in 2018.

Soil pH In 2018, the soil pH showed an increase from the 2017 value in all depths and areas of the plantation, except in the unirrigated surface area, where a small decrease was observed. The pH of the leachate has historically been relatively high which may impact the soil pH.

Soil electrical conductivity or salinity The conductivity in the irrigated area was not as high in the fall of 2018 as it was in the fall of 2017. The conductivity decreased from 3.8 dS/m after irrigation in 2017 to 1.54 ds/m after irrigation in 2018. The conductivity in the unirrigated area remained at a low level again. Typically, the soil conductivity rises during the irrigation season, then returns to pre-irrigation levels the following spring, after the leachate constituents that increase conductivity (sulphate, sodium) leach form the soil with rain and snowmelt. The spring soil conductivity concentration in 2018 returned to near pre-irrigation levels at 0.70 dS/m.

Soil sodium absorption ratio (SAR) SAR analysis was done on all sample depths in spring and fall of 2018 to assess the impact of leachate-origin sodium on soil permeability. The SAR analysis is done on a saturated paste extract of soil and is the ratio of the amount of soluble sodium to calcium plus magnesium in the soil. SAR is an assessment of whether the presence of sodium in the soil is negatively impacting soil structure and permeability. The sodium content of the surface soil has shown a significant increase from the pre-leachate concentration since leachate irrigation began, therefore, it is evident that the leachate is contributing to the sodium content of the soil.

All soil depths in both the irrigated and unirrigated area of the plantation except the irrigated surface soil showed an increase in SAR from the post-leachate value in 2017, to the post-leachate value in 2018. All depths of the unirrigated area of the plantation saw only a slight increase and SAR levels remain below 1.0 in this area. In the irrigated area, the greatest increase in SAR was observed in the 45-90 cm depth, from 1.89 in 2017 to 10.60 in 2018. In the irrigated surface soil, the SAR level remained elevated at 7.42, but decreased slightly from the 2017 value of 8.20. In the spring of 2018, after flushing throughout the winter, the SAR in the surface soil decreased to 4.18.

A SAR value of <2.1 indicates that there is no risk of sodium permeability hazard in the soil, SAR of 2.1 to 12 indicates increasing risk and a SAR above 12 indicates that the soil is ‘sodic’ and that there is a high risk of sodium-induced damage to soil structure.

In order to observe the initial soil changes at the new plantation, these same parameters should be assessed again in spring and fall of 2019.

DEEP SOIL SAMPLING RESULTS

In the fall of 2018, soil samples were collected from two deeper depths in the soil, 15-45 cm and 45-90 cm in both irrigated and unirrigated areas of the site to understand soil conditions at depth, before leachate irrigation began and after. Samples were tested for nitrate-N, sulphate-S, chloride, pH and electrical conductivity. Of these parameters, the leachate contains a significant amount of chloride, and a small amount of nitrate. It has a high pH (~8) and has high conductivity.

The results of deep soil monitoring in fall 2018 showed elevated chloride levels in the irrigated area of both deep soil depths again. Chloride in the 45-90 cm depth increased from 115 mg/kg in 2017 to 186 mg/kg in 2018. However, chloride in the 15-45 cm depth decreased from 241 mg/kg in 2017 to 118 mg/kg in 2018. The unirrigated areas saw a larger increase in chloride at depth than in 2017. The unirrigated areas have chloride concentrations of around 60 mg/kg. Chloride concentrations are greatest in the deepest soil depth and the least at the soil surface in 2018. This indicates that chloride is moving through the soil column, which is expected as chloride is a fast moving parameter in water.

Sulphate and conductivity levels also showed increases from the fall of 2017 to the fall of 2018, in most depths of the irrigated and unirrigated area of the plantation. As noted for chloride, the concentration of sulphate and conductivity is greater at depth than at the surface in 2018, indicating leaching through the soil column. These increases were also seen at the old plantation after irrigation began.

Nitrate concentrations increased from 2017 concentrations at all subsurface soil depths in both the irrigated and unirrigated area in 2018. The concentrations seen in the subsurface are similar to the surface soil, and are within the normal range for tree growth. The pH increased from 2017 in both depths of the irrigated and the unirrigated areas of the plantation after leachate irrigation in 2018.

Samples at these two deeper depths will be collected again in the fall of 2019 at the new plantation in order to monitor the horizontal movement of soluble parameters on the site at depth.

SOIL TRACE ELEMENT STATUS

Contaminated Sites Regulation (CSR) trace elements were assessed in the surface soil of both the irrigated and unirrigated areas of the site in 2018. Table 11 contains the collected surface soil trace element data from May 2017 to October 2018.

There was no significant change in the soil concentration of these trace elements in either the irrigated or unirrigated soil from the pre-leachate value in the spring of 2017 to the post-leachate value in the fall of 2018. Most parameters saw a slight decrease in 2018. No large change in soil trace element concentrations is expected as the leachate contains low levels of trace elements. However, CSR trace elements will continue to be tested to monitor possible changes in the future.

TISSUE ANALYSIS

Tissue analysis was not assessed in 2018. Tissue analysis will be considered in the future.

4. SUMMARY AND RECOMMENDATIONS

4.1 SUMMARY OF 2018 MONITORING RESULTS

1. Soil samples were taken at the harvested plantation site in the fall of 2018, after two years without leachate or any irrigation. The results showed that the soil has improved significantly in quality, with decreases in previously elevated parameters such as SAR, conductivity, sodium, boron, chloride, and sulphur. The proportions of the cations calcium, magnesium, and sodium appear to be adjusting closer to the ratio observed before leachate irrigation as well. The harvested site will continue to grow naturally, without any irrigation, and will not be replanted. This site will no longer be sampled yearly. 2. The new plantation at the ASRDF has now been established for two seasons of leachate irrigation. 3. Soil samples were taken from the new plantation in the spring before leachate irrigation began and again in the fall after leachate irrigation finished for the season. 4. The results from the fall soil sampling showed that some parameters, including chloride, sodium, sulphur, SAR, and conductivity decreased in concentration in the irrigated surface soil from the 2017 values. However, these parameters remain elevated compared to pre- leachate values. These parameters are elevated in the leachate, and therefore were expected to increase in the soil of the irrigated area after irrigation began. 5. Deep soil sampling in fall 2018 (15-45 and 45-90 cm) showed increases in concentration from the 2017 values in chloride, sulphate, and conductivity in the irrigated and unirrigated areas of the plantation.

4.2 RECOMMENDATIONS FOR 2019 IRRIGATION SEASON AND MONITORING PROGRAM

1. Continue the currently established soil monitoring program at the new plantation in 2019, as follows: 2. Soil monitoring should be conducted twice during the irrigation season – prior to startup in the spring and after shutdown in the fall. 3. Spring soil monitoring in 2019 should be done at the 0-15 cm depth only and in the irrigated area of the site only. 4. Soil monitoring in fall 2019 should be done at 0-15 cm, 15-45 cm and 45-90 cm depths on irrigated and non-irrigated areas of the property. It should be done as 8 subsamples at the 0-15 cm depth and 4 subsamples at the 15-45 and 45-90 cm depths. 5. Analyze the shallow soil samples (0-15 cm depth) in spring and fall for Nitrate-N, ammonium-N, P, K, Ca, Mg, S, Na, Cl, B, Mn, Zn, Cu and Fe, CSR trace elements, and quality parameters: Sodium Absorption Ratio (SAR), pH and conductivity (same parameters as in 2018). 6. Analyze the deep soil samples (15-45 and 45-90 cm depths) for nitrate-N, sulphate-S, conductivity, pH, chloride and SAR (same parameters as in 2018).

D. DEFINITIONS 1. In this bylaw, unless the context otherwise requires: Adequately Secured means that Municipal Solid Waste is contained or immobilized in such a way that the Municipal Solid Waste cannot leak, spill, blow, fall or otherwise be dislodged from a vehicle and/or trailer attached to a vehicle entering and exiting a RDF. For an open truck box or trailer this means that a tarp and/or cargo net or equivalent secured to the truck box and/or trailer is required. The tarp and/or cargo net or equivalent must not be able to blow off, fall or otherwise be dislodged from a vehicle and/or trailer entering or exiting a RDF.

Asphalt Roofing – Clean means loads containing exclusively waste asphalt roofing that is free of contamination other than nails and screws. This material is considered Municipal Solid Waste.

Asphalt Roofing – Minor Contamination means loads containing primarily waste asphalt roofing that also contain minor amounts of contamination other than nails and screws such as paper, wood and miscellaneous refuse. This material is considered Municipal Solid Waste.

Asphalt Roofing – Major Contamination means loads containing waste asphalt roofing that also contain major amounts of contamination other than nails and screws such as paper, wood and miscellaneous refuse. This material is considered Municipal Solid Waste.

Batteries - Automotive means electro-chemical cells contained in plastic cases consisting of lead and lead oxide plates and containing a mixture of acids, which are used to supply an electric power source. This waste material is considered Municipal Solid Waste.

Batteries - Household means rechargeable or non-rechargeable batteries commonly used for household purposes including, but not limited to A, AA, AAA, C, D, and 9 volt batteries. This waste material is considered Municipal Solid Waste.

Biosolids means stabilized sewage sludge with more than 30% moisture resulting from a waste water treatment process. This waste material is not considered Municipal Solid Waste and therefore requires pre-approval for disposal.

Bulky Waste means Municipal Solid Waste articles with a volume greater than one and one half (1.5) cubic metres, or materials greater than two and one-half (2.5) metres in length; or articles that the Manager determines require special or additional handling and/or disposal techniques.
