HARTLAND LANDFILL – LANDFILL GAS MONITORING 2017 ANNUAL REPORT

EXECUTIVE SUMMARY

Hartland landfill provides solid waste disposal services for the Capital Regional District (CRD). The landfill is a multi-purpose facility providing collection services for recyclable materials, household hazardous waste, items covered by product stewardship, and disposal of municipal solid waste and Controlled Waste. The site operates under an Operational Certificate under the Environmental Management Act, issued by the BC Ministry of Environment and Climate Change Strategy (MOE), and follows an Operating Plan required under the Operational Certificate.

The operating landfill footprint is approximately 33 hectares with an estimated 7,100,000 tonnes of municipal solid waste landfill, as of the end of 2017. Total annual disposal was 157,638 tonnes of residential, commercial and industrial waste. When the landfill reaches planned final filling elevations it will occupy approximately 48 hectares, with a volume of approximately 14,500,000 m3 of municipal solid waste.

This report fulfills the annual reporting requirements set out in the Landfill Operational Certificate and the Landfill Gas Management Regulation. Landfill gas (LFG) collection/management at Hartland includes collection and utilization infrastructure, generation modelling and monitoring (utilization, perimeter gas probes, hotspot monitoring and speciation).

LFG collection and/or management at Hartland includes the following components:

• Gas collection infrastructure, including cover systems, collection pipes, wells and blowers to facilitate gas collection and utilization.

• Landfill gas utilization facility that produces electricity for the BC Hydro grid.

• Landfill gas monitoring system, including collection system, hotspot and subsurface monitoring programs.

• Methane production and gas generation modelling rates given landfill waste volumes and decomposition rates.

GAS COLLECTION AND UTILIZATION

In 2017, the gas collection system consisted of 67 vertical wells and 74 horizontal wells, for a total of 141 wells. In 2017, 12 non-productive wells were removed from service, 22 new wells were connected to the system (Phase 2, Cell 2), and 5 horizontal wells were installed in completed lifts in Phase 2, Cell 3. The well field was balanced monthly in 2017, as recommended by the Landfill Gas Management Facilities Design Guidelines.

The CRD continues to progress filling plans consistent with the conceptual designs developed by Conestoga-Rovers & Associates (2011). In 2017, LFG collection efficiency was 67.7%, which is within estimated ranges according to the Landfill Gas Management Plan. Total fugitive greenhouse gas (GHG) emissions generated from the landfill for 2017 are estimated at 64,173 tonnes CO2e. A summary of landfill gas production and collection is provided below (based on the LFG generation model). Emissions have been normalized to 50% methane in standard cubic feet per minute (scfm).

MONITORING

Hartland landfill has several monitoring programs to assess the effectiveness of the LFG collection infrastructure. The following summarizes the components of the program:

Collection and utilization system monitoring to evaluate changes in gas quality over time and to document data for gas collection and gas utilization to assess collection efficiency and total emissions from the landfill.

Monitoring of subsurface perimeter and building foundation probes to assess the potential for subsurface LFG migration at the eastern landfill boundary and at on-site buildings for compliance with BC Landfill Criteria, and for worker and public health and safety.

Surface emissions and hotspot monitoring to verify the effectiveness of cover and the LFG collection system in order to identify health and safety risks associated with fugitive LFG emissions.

Landfill Gas Speciation to assess the composition of gas with regard to volatile organic compounds, sulphur gases and typical landfill gases in order to calculate ambient dilution concentrations for health and safety and infrastructure integrity purposes.

GAS GENERATION

In 2017, Hartland landfill generated 7,957 tonnes of methane, based on the model provided by MOE. The BC Landfill Gas Management Regulation requires landfills that generate greater than 1,000 tonnes of CH4 per year of methane to develop LFG management plans. These plans set out targets for system designs to achieve 75% collection efficiency 4 years after implementation. The Hartland landfill plan was submitted to the MOE in April 2012 with an implementation target of the end of 2016.

An organics diversion program and ban took effect in January 2015. Diversion of a large portion of highly decomposable waste stream from the landfill will result in a decrease in overall gas production.

ADDITIONAL REPORTING FRAMEWORKS

LFG emissions and related data are reported to numerous reporting frameworks throughout the year and include:

• Environment and Climate Change Canada: o Facility GHG Reporting (Final Emissions Reporting) o National Pollutant Release Inventory o Environment & Climate Change Canada Landfill Gas Survey • BC Ministry of Environment o GHG Reporting (Industrial Emissions) • Statistics Canada o Electricity Supply and Disposition Survey (annual and monthly) o Survey of Electric Power Thermal Generating Station Fuel Consumption

HARTLAND LANDFILL – LANDFILL GAS MONITORING 2017 ANNUAL REPORT

1.0 INTRODUCTION

Hartland landfill provides solid waste disposal services for the Capital Regional District (CRD). The landfill is a multi-purpose facility providing collection services for recyclable materials, household hazardous waste, extended producer responsibility products, salvageable items, as well as disposal services for municipal solid waste and Controlled Waste. Landfill operations are guided by the Design, Operations and Closure Plan, the Landfill Operational Certificate issued by the BC Ministry of Environment and Climate Change Strategy (MOE), and the CRD’s Solid Waste Management Plan.

This report fulfills requirements of the Landfill Operational Certificate and the Landfill Gas Management Regulation for annual reporting of gas management/controls. Landfill gas (LFG) collection/management at Hartland includes collection and utilization infrastructure, generation modelling and monitoring (utilization, perimeter gas probes, hotspot monitoring and speciation).

LFG is primarily made up of methane and carbon dioxide with small amounts of water vapour, oxygen, nitrogen and trace gases. Trace gases include hydrogen sulphide, ammonia, nitrous oxide, volatile organic compounds and chlorofluorocarbons. Risks associated with LFG include asphyxiation, flammability (between 5% and 15% methane by volume), toxicity, odour and greenhouse gas (GHG) emissions.

The objective of a LFG collection system is to mitigate fugitive emissions and reduce the potential for subsurface, lateral gas migration. Hartland landfill has implemented a LFG collection system to minimize fugitive emissions and a monitoring program is maintained to assess the effectiveness of these controls.

2.0 SITE DESCRIPTION

The Hartland landfill is situated on 320 hectares within the District of Saanich. Mount Work Regional Park is located to the west, parkland and the Heal’s Rifle Range lies to the north, residential properties lie to the east, and undeveloped CRD property is located to the south.

The climate in the area is classified as “Cool Mediterranean”, due to warm, dry summers and cool, wet winters. Annual precipitation is around 1,000 mm per year. The site is surrounded by bedrock; discontinuous bedrock fractures have been identified.

The CRD took over operation of the landfill site in 1985. Prior to that, it was privately owned and operated. The landfill currently occupies approximately 33 hectares with an estimated 7,100,000 tonnes of municipal solid waste in place as of the end of 2017. When the landfill reaches final capacity, it will occupy approximately 48 hectares and contain approximately 14,500,000 tonnes of municipal solid waste. The average annual disposal rate for the last 5 years is approximately 137,000 tonnes, which comprises residential, commercial and industrial wastes.

The landfill comprises 2 operational areas: Phase 1 was operational between the 1950s and 1997, and has final cover. Phase 2 comprises the current active area of the landfill, which began in 1997. Phase 1 is unlined and covered with a combination geo-membrane/clay cap. Phase 2 was constructed within a former lake basin (now referred to as the Phase 2 basin); it is partially lined and relies on negative pressure (hydraulic trap) to contain leachate. Development of the Hartland landfill is guided conceptually by the Cell Development Plan from the Hartland Landfill Phase 2 Long Term Leachate Management Plan (Sperling Hansen Associates, June 2007); an updated master filling plan is currently being prepared and is expected by the end of 2018.

3.0 REGULATORY REQUIREMENTS

There are a number of provincial and federal regulations that apply to LFG management, emissions management and reporting. Key regulations are listed below.

3.1 Landfill Gas Management Regulation

In January 2009, the BC Landfill Gas Management Regulation came into effect dictating province-wide criteria for LFG capture with the primary aim to reduce GHG emissions from landfills. The regulation requires that landfills receiving greater than 10,000 tonnes of refuse per year, or have 100,000 tonnes of refuse in place, must calculate (using a specific LFG generation model) the quantity of gas produced for submission to the MOE. Calculated gas generation rates greater than 1,000 tonnes per year requires development of a Landfill Gas Management Plan (LFGMP) by a qualified professional. Implementation must be completed within 4 years and is directed by the Landfill Gas Management Facilities Design Guidelines, 2010 (the Design Guidelines), a guidance document. The LFGMP describes how, what and when gas collection system components should be installed to meet the expected 75% collection efficiency. Collection efficiency must be attained 4 years after implementation of the LFGMP, which was 2016, for the Hartland landfill. The Design Guidelines also require monthly balancing of gas collection well fields.

3.2 Health and Safety Regulations

WorkSafeBC: Many of the compounds in LFG, particularly methane, hydrogen sulphide and individual volatile organic compounds have exposure limits set out within WorkSafeBC regulations. The Hartland landfill must comply with these limits.

The BC Landfill Criteria for Municipal Solid Waste, 2016: dictates that combustible gas must not exceed specific limits at the landfill perimeter, and all on-site buildings. As well, it must be managed to ensure there is no public threat or nuisance, and that provincial and federal air quality objectives are met. Annual reporting and interpretation of this data is a requirement under the Operational Certificate.

3.3 Additional Emissions Reporting

There are additional federal and provincial emissions reporting frameworks requiring Hartland LFG emissions or related data. A summary of these reporting programs is provided in Table 1.

4.0 LANDFILL GAS GENERATION

Decomposition of refuse creates LFG; the composition and amount of gas generated varies based on factors, such as amount, type and age of waste, as well as environmental conditions, such as moisture content. LFG composition and generation rates are discussed in Section 6.1.

Peak gas generation occurs during the first 1-3 years after disposal. Initially, decomposition of waste is an aerobic process and produces mainly carbon dioxide. As oxygen is depleted, the decomposition occurs under anaerobic conditions. The total waste input and waste composition affects overall gas generation rates. For clarity, it is important to note that gas production is the total amount of gas predicted to be produced by the landfill given waste composition and existing waste in place.

4.1 Quantity and Sources of Municipal Waste Received

Quantity of LFG production is dependent on the amount and type of waste received. In 2017, the Hartland landfill received 157,638 tonnes of waste, which included 144,368 tonnes of general refuse, 10,104 tonnes of Controlled Waste and 3,166 tonnes of asbestos. Waste volumes have increased over the last 2 years, as a result of economic conditions, as well as the closure and transferred ownership of a local private landfill that receives demolition material.

Figure 1 Annual Waste Tonnages Received or Estimated for Hartland Landfill from 1980-2017

Waste composition is used to calculate methane generation rates to determine overall LFG generation; it is discussed in Section 9.0. From 2014-2015, a combination of weigh scale information and the 2010 Waste Stream Composition Study was used. A waste composition study was completed in 2016 and has been used to update waste composition back to the onset of the kitchen scraps diversion program in 2014. For 2014 through 2016, the waste composition is estimated to be 27% relatively inert, 52% moderately decomposable and 21% decomposable. The decrease in the portion of decomposable waste (29% for 2010-2013) can be directly attributed to the implementation of the kitchen scraps ban.

Page 6 Hartland Landfill – Landfill Gas Monitoring 2017 Annual Report

Details of all waste composition studies are included with the gas generation data in Appendix A, including, methane generation potentials, a summary of waste sources and diversion, as required under the Landfill Gas Management Regulation.

Waste composition studies do not quantify Controlled Waste. Controlled Waste is classified by the CRD as wastes that, due to environmental or health and safety considerations, require special handling. Controlled Waste deposited at the site is measured by scale and classified by type. For the purpose of this report, and on consultant recommendation, Controlled Waste is considered relatively inert, with the exception of Controlled Waste classified as ‘Miscellaneous’, which is considered to be decomposable. Controlled Waste totals are incorporated in the quantities for relatively inert and decomposable waste in the model.

4.2 Waste Diversion

The CRD has implemented an organics (kitchen scraps) diversion program and ban that took effect January 1, 2015. However, incentive programs were implemented in 2013 and 2014 to encourage compliance prior to the implementation of the landfill ban. As a result, more than 5,000 tonnes of organics were diverted from the landfill in 2013 and more than 15,000 tonnes in 2014. The termination of the incentive program in 2015 has resulted in difficulties tracking diverted organics; as a result, a conservative estimate of 20,000 tonnes has been used for 2015 through 2017.

Diversion of a portion of highly decomposable waste from the landfill will result in a decrease in overall gas production. The 2016 waste composition study indicated organic material now comprises 20.1% of the waste stream, compared to 30% prior to the kitchen scraps ban. The Hartland Landfill Gas Management Plan predicted a decrease in gas production within the first 1-3 years following the implementation of the diversion program. Annual modelled methane production since the implementation of the diversion program has confirmed peak landfill gas production and a subsequent decline since the implementation of the organics ban in 2015.

4.3 Health and Safety

LFG is flammable, toxic and poses an asphyxiation risk to landfill employees and contractors on site. Specifically:

• LFG can accumulate in confined spaces or low-lying area with poor air circulation, which can pose an asphyxiation risk due to the displacement of oxygen. • Both trace gases and major gas constituents can result in acute toxicity if exposure occurs at high enough concentrations. • Trace gases, usually associated with sulphur compounds, can create odours. • Methane is explosive at concentrations between 5 and 15%. It is also a GHG with 25 times the Global Warming Potential of carbon dioxide. There is also potential for gas to laterally migrate off site. When gas pressure builds up in the landfill, gas migrates via cracks, soil pores, and/or fractures to equalize with the surrounding atmosphere. This includes migrating through permeable cover systems or subsurface migration toward adjacent properties. The main objective of a LFG collection system is to mitigate the above risks and reduce the potential for subsurface, lateral gas migration. However, while lateral movement can be mitigated with LFG collection and control, there will still be fugitive LFG emissions on site. A number of factors influence this, such as atmospheric pressure, groundwater level, the gas pressure in the refuse mass, and permeability of cover systems. Gas collection system operation and utilization is discussed in sections 5.0 and 6.0, and monitoring programs are discussed in Section 8.0.

Hartland Landfill – Landfill Gas Monitoring 2017 Annual Report Page 7

5.0 LANDFILL GAS COLLECTION AND MONITORING INFRASTRUCTURE

Systems to control and monitor fugitive LFG emissions have been implemented at Hartland landfill. The objective of these controls is to:

• protect employee and public health and safety • prevent migration of gas off-property or into on-site buildings • reduce GHG • capture gas for energy recovery • control odour The LFG management system, originally installed in 1990, was upgraded in 1996 in conjunction with the planned closure of Phase 1. A temporary flare was erected and connected to 12 vertical wells. A permanent blower station, header and lateral collectors, and a groundflare were installed and commissioned in 1998. The blower station consists of three 1,300-scfm blowers, 2 of which have variable frequency drives that offer vacuum control. The vacuum draws gas from connected wells via a series of 150-mm-diameter laterals that connect to a header that ranges from 200-400 mm. The lateral and header pipes are all constructed of high-density polyethylene. Currently, gas is extracted from a network of vertical and horizontal gas collection wells and directed to the generator. Excess gas is directed to a candlestick flare, while the existing groundflare is used during extended generator downtime.

In 2004, Maxim Power Corp., under a contract with the CRD, installed and commenced operation of a 1.6-MW generator to utilize LFG to generate electricity, which is still in operation today. In 2013, the CRD took over ownership and operation of the generator and associated controls. Operation, maintenance and electricity generation has remained the same.

The current LFG management system consists of:

• An extraction well network, including vertical and horizontal wells. • A conveyance system incorporating branch, lateral and header pipes to convey the collected LFG from the extraction network to the LFG utilization facility or flares. • A LFG destruction facility with moisture separators, centrifugal blowers, flares, piping and electrical service. • A 1.6-MW generator for LFG utilization. • A LFG monitoring program. • A subsurface gas migration monitoring network that includes gas monitoring probes located adjacent to the eastern property boundary and the perimeter of on-site building foundations. 5.1.1 Vertical Gas Extraction Wells

The gas system started with 34 vertical wells, many of them dual zone. Seven dual zone vertical wells were added for the West Crest closure project. By the end of 2016, there were 25 dual zone vertical wells and 24 shallow vertical wells operating. Vertical wells are spaced at 50-m intervals. The well design includes a 760-mm borehole with 1 shallow and 1 deep extraction pipe. The dual zone wells are up to 30 m into the waste, while the shallow wells are completed to a depth of 10-16 m. The deep wells are constructed with a 200-mm-diameter slotted section in the deepest zone, a 150-mm-diameter solid middle section and a 100-mm-diameter solid section through to grade. The shallow wells are constructed with a 150-mm- diameter slotted section, with slots terminating between 4-6 m from the surface and a 100-mm-diameter solid section through to grade.

Page 8 Hartland Landfill – Landfill Gas Monitoring 2017 Annual Report

5.1.2 Horizontal Gas Extraction Wells

Prior to 2012, the horizontal wells were placed every 45-50 m on centre, extending 100-200 m in length, and trenched into the refuse with a vacuum applied only at 1 end. The horizontal wells were laid every 10- 12 m vertically and offset from the layer below. Horizontal wells were installed in trenches 1 m wide and 1.7 m deep trenched in garbage with a 150-mm bed of aggregate. The wells were then covered with aggregate and a layer of geotextile. The terminus of each well is solid pipe with a clay plug. The wells slope at 2-3% when installed.

Installation of new gas collection infrastructure has changed with the implementation of the LFGMP in 2012. The density of horizontal wells has increased from 45-50 m, to 20 m on centre. Wells are placed on each vertical lift, approximately every 4 m, with each offset from the lower trench alignment. The horizontal wells are constructed using 15-m-long slotted pipe sections friction fit, into 3-m-long solid sections of 200-mm high-density polyethylene DR11 pipe. The pipes overlap by 1 m to allow for articulation due to settlement. The piping is then covered with 75-mm x 19-mm clear aggregate and wrapped in geotextile cloth to prevent intrusion of fine sediments. All new horizontal wells over 150 m in length are connected to laterals at both ends. By the end of 2017, 22 new horizontal wells were activated (installed in the 175 and 179 mASL lifts of Cell 2) and 5 new wells were installed in the 150 mASL lift in Cell 3.

See Figure 2 for the general location and layout of the LFG infrastructure.

5.2 Collection and Treatment System Monitoring: Gas Well Field Operation and Data

Table 2 shows the number and type of gas wells installed and operating in 2016. A complete summary of changes to the gas well field is provided in Appendix B. In 2017, 22 new wells were activated and 5 new wells were installed. An additional 9 wells installed in 2016 are not ready for activation, but are being monitored for sufficient LFG production. A complete summary of all gas wells, including installation and deactivation dates, is included in Appendix B. Due to a lack of LFG production, and to improve well inventory and tracking, 12 wells were removed from the monthly monitoring program and labelled as ‘inactive’.

The use of gravel as interim cover facilitates easy drainage of leachate for maintenance of the hydraulic trap leachate collection system; however, the permeable nature of the gravel is not conducive to gas capture and can promote oxygen intrusion into the waste mass. Introduction of oxygen into a gas well or refuse can lead to subsurface fires. To minimize this potential and maximize gas collection, each gas collection well has a head with a control valve to regulate the vacuum exerted on the individual well. This controls the flow of gas from the well into the gas collection system. Well field balancing is required on a monthly basis to assess and adjust individual wells to optimize overall gas flows and composition.

CRD staff monitor gas wells for methane, carbon dioxide, oxygen, balance gas, static pressure, differential pressure, temperature and flow on a monthly basis. The well field must be measured and balanced at least once per month and more often if there are changes in gas composition, or if there are swings in the system vacuum measured at the gas plant. There are many factors that impact gas generation, so frequent well adjustments are critical to optimize the flow and methane content. Ideally, constant vacuum is applied at a well so that gas is drawn at approximately the same rate that it is being generated (a target of <3% oxygen, and <20% nitrogen/balance gas is desirable).

Data from the well field, including individual well gas flows, is provided in Appendices B2 and B3. The well field was balanced 12 times in 2017, as recommended by the Design Guidelines; however, no data was recorded in February due to a data logging error. The full data set is included in Appendices B4 and B5. Table 3 shows that the 10 most productive wells contribute 41% of the total gas volume. Figure 3 depicts gas collection by well as it contributes to the total gas collected. Reported methane flows for each well appear lower compared to previous years due to 1 month of missing data.

If a gas well does not produce enough methane, the valve is often turned down or off. In 2017, 12 wells did not produce adequate amounts of methane and have been labelled as ‘inactive’. It is recommended that non-producing wells be removed from the monitoring program and labelled as ‘inactive’ after 18 months.

6.0 LANDFILL GAS UTILIZATION AND COLLECTION

The volume of collected LFG is measured by flow meters at the LFG plant and recorded on the CRD SCADA system. The data is compiled to determine collection and utilization rates, and then compared to the generation model to estimate the collection efficiency of the system. Utilization of LFG refers only to the gas burned by the generator for electricity production, while collection refers to all gas drawn into the gas plant. Table 4 shows a summary of gas collection, generation, and overall collection efficiency. Figures in the following section illustrate the collection efficiency for the last several years (2004-2016) and the full set of data is provided in Appendix C1.

The LFG utilization facility shown in Figure 4 consists of 6 major components:

1. Conditioning Skid: Receives the LFG from the CRD collection/blower system. The conditioning skid cools the gas and reduces moisture, which drains into the condensate collection system. It also reduces the amount of siloxane, which increases wear and tear on generator components. 2. Refrigeration Plant: Provides coolant to the conditioning skid by circulating it, as required, to maintain the LFG at 2°C. 3. Engine: 20-cylinder, 2,200-HP Caterpillar. The engine runs a direct drive 1,200-rpm, 1.6-MW generator. Electricity produced is fed into the BC Hydro grid. 4. Transformer: The unit converts 600 V to 25 kV. 5. Switch Gear: Monitors stability of the line input to the BC Hydro grid. 6. Master Control Building: Houses the controls that interconnect the utilization facility with the collection system. It also provides system operation controls, such as continuous quality, flow rate and pressure monitoring. The CRD has upgraded its system controls to communicate with the utilization facility. Gas is drawn into the facility by the blowers and passed through the conditioning skid. An automated valve maintains the required gas pressure for the generator while excess gas is fed back to the candlestick flare. Gas is only directed to the groundflare during extended periods of generator downtime, due to maintenance or BC Hydro issues.

6.1 Gas Composition

Gas composition is monitored monthly at each individual well and continuously at the gas plant. A comprehensive summary of gas concentration by well is provided in Appendix C. On average, the LFG at the gas plant was comprised of 51.3% methane and 0.6% oxygen.

Collection efficiency improved beginning in 2012 due to the installation/connection of several horizontal wells in late 2011, as well as the connection of new wells associated with the Phase 2, Cell 1 closure. Further improvements in collection efficiency were observed in 2013, as a result of installation of 6 new horizontal collection wells in Phase 2 and implementation of the LFGMP.

This decrease can be attributed to inconsistencies in well field balancing. In 2016, LFG collection efficiency was 61.8% (Table 4 and Figure 6). In 2017, collection efficiency increased to 67.7%. The increase can be attributed to improved well field balancing and increased gas collection at key wells. Further detail on collection efficiency, and the LFGMP implementation status, is also provided in Section 6.1.2.

Since 2013, collection efficiency has varied around 60% with a maximum of 67.7% in 2017. These rates are within the estimated range predicted by the LFGMP and demonstrate that Hartland landfill is meeting the expectations of the LFGMP (Figure 5).

Total fugitive GHG emissions generated from the landfill for 2017 were estimated at 64,173 tonnes CO2e, which is a 15% decrease from 2016 and a 40% decrease from 2012 (Figure 7). As predicted, GHG emissions continue to decline, as a result of the organics (kitchen scraps) ban at the beginning of 2015, and continued success of the CRD’s waste diversion initiatives.

It should be noted, that the Global Warming Potential for methane was updated to 25 (from 21) in 2014. In addition, certain conversion factors were updated in 2017, resulting in slight differences in previously reported numbers. Overall collection efficiency and GHG emissions remain largely the same.

6.1.1 Destruction Devices and Usage

Table 5 shows the average gas collected from 2011-2017 and flows through utilization devices (generator, candlestick or groundflare). Flaring of gas usually occurs when gas collection exceeds generator capacity or during generator downtime. The generator was offline due to repairs from August 2015-June 2016, at which time gas was directed exclusively through the groundflare.

The Design Guidelines specify that a candlestick flare should not be used as a primary combustion device, but can be utilized as a backup combustion device when flows exceed the capacity of other approved devices. As a result, 50% or more of the total LFG collected should be directed through the groundflare or generator. Since 2009, the generator and/or groundflare have been the primary destruction devices. In 2016, 69.3% of the gas was directed through approved destruction devices.

6.1.2 Landfill Gas Management Plan Implementation Status

The CRD has implemented the conceptual design in the LFGMP. However, since the plan was prepared, some operational changes have occurred, which are summarized below:

• 2012 – Alignment of horizontal wells changed from east-west, as specified in the LFGMP, to north- south due to the master fill plan cell phasing and progression. • 2012/2013 – Relocation and reconfiguration of Controlled Waste disposal areas. Controlled Waste, initially landfilled in clay-lined cells, is now trenched into refuse. Landfilling was conducted over the Controlled Waste area expanding the available footprint for Cell 2. This benefits overall collection in that it allows gas wells to be installed in Controlled Waste areas that would otherwise be inappropriate due to clay. • 2014 – Installation of vertical gas wells has been delayed pending further review of efficacy due to leachate inundation or minimal gas production. Vertical gas wells installed in recently closed areas (2012) were not productive due to density of horizontal wells and overlapping areas-of-influence. • 2014 – Since implementation of the LFGMP, horizontal well installation depths have been reduced (made shallower). The proposed deeper wells were intended to accelerate activation; however, this was not actualized and the deeper wells triggered odour and safety issues during installation. As a result, this part of the LFGMP was revised to allow for shallow wells. The shallow wells have fewer health and safety considerations, are less expensive to install, and can be activated in the same timeframe as deeper wells specified in the plan. • 2015/016 – Filling plan sequencing has changed since the plan was prepared. These changes represent schedule variations rather than whole scale deviations from the LFGMP. Changes include:

o Phase 2, Cell 2 vertical extension by 2 lifts to allow time for completion of the cliff quarry and construction of Cell 3.

Page 20 Hartland Landfill – Landfill Gas Monitoring 2017 Annual Report

o February 2017 – A bypass line valve was opened at the gas plant to reduce back pressure on the well field and increase gas flows to the plant. As a result, flows increased by 50-100 scfm. The LFG collection system is designed to reach 75% collection efficiency, as per the Design Guidelines. Based on the targeted collection efficiency was expected to be reached by 2016; however, current collection efficiency is 67.7% and within estimated ranges according to the LFGMP (Figure 5).

7.0 OPERATIONAL UPDATES

Detailed operational updates and changes are outlined in the Hartland Landfill Annual Operations Report. Pertinent changes are detailed below as they relate to LFG.

• Landfilling commenced in Phase 2, Cell 3 in September 2016. • Phase 2 temporary cover (30 mil LLDPE) covering the southeast corner of Phase 2, Cell 2 after final gas well installation in the third quarter of 2017 • A renewal Natural Gas study was initiated, which looked at the possibility of pipeline quality gas to the FortisBC network. The study is ongoing. 7.1 System Performance and Maintenance

The gas collection system operates continuously except when there is a power failure or alarms that result in system shutdown. In the event of a stoppage, the system can be remotely restarted by on-call staff. Table 6 summarizes collection system downtime (i.e., no vacuum applied on the collection system).

Table 6 Summary of 2017 Blower Downtime by Month

Month Downtime (minutes) January 66 February 1,259 March 0 April 1,473 May 68 June 139 July 0 August 127 September 99 October 48 November 581 December 373 Total 4,233 minutes (2.94 Days)

In 2017, the overall collection system downtime was less than 3 days. All downtime can be attributed to power outages, and planned/unplanned maintenance.

Table 7 summarizes the performance of the generator in 2017, including electricity production, which compares actual operating hours to available operating hours for each month. Average energy production for 2017 was 80%.

7.1.1 Generator Emissions

Table 8 reports generator emissions results for 2008-2017. A stack test was not completed in 2017. No emissions data is available for 2015 due to generator downtime. The emissions data is compared to a baseline study conducted in 2004 that modelled emissions against applicable limits. The data is reviewed to ensure that current emissions rates are consistent with those used in the model.

8.1 Subsurface Gas Monitoring – Perimeter and Foundation Probes

Since 1996, 2 types of monitoring probes, perimeter probes and foundation/trench probes, are installed at Hartland landfill that monitor subsurface gas migration, if any. The 2016 BC Landfill Criteria for Municipal Solid Waste requires that combustible gases in soils at the landfill property boundary must not exceed the lower explosive limit (LEL) and that combustible gas in any on- or off-site structure and/or facility shall not exceed 20% of the LEL. The LEL for methane is 5%. There are 5 perimeter monitoring probes installed (drilled into bedrock) along the eastern property line and 12 trench monitoring probes around on-site buildings (Figure 8). These probes are monitored quarterly.

Through installation and improvement of the LFG collection system, the CRD has reduced the risk of offsite gas migration; however, monitoring continues, as required, to comply with MOE requirements and to confirm worker and public health and safety.

Methodology

The perimeter and foundation probes are monitored using a LANDTEC Gas Analyzer and Extraction Monitor GEM 2000+. Each probe is monitored quarterly for pressure, oxygen, carbon dioxide, and methane, as well as groundwater elevation (where applicable). Atmospheric conditions during each monitoring event are also recorded. A complete monitoring methodology, probe locations, details, and data from the perimeter and building foundation probes are provided in Appendix D.

Results and Recommendations – Perimeter Probes

All probes were monitored according to the standard operating procedures 4 times in 2017; data is presented in Table 10, maximum values are shown in Table 11. There was no detectable methane recorded in 2017. Consistent with historical data, CO2 levels are slightly higher in the shallower ‘B’ probes than the deeper ‘A’ probes. Elevated carbon dioxide levels may give an early indication of the presence of LFG; however, no unusually high CO2 levels were observed. Ongoing monitoring will continue to determine if any trends develop.

Foundation probes were monitored 4 times in 2017, which is in compliance with MOE requirements (Table 12 and Table 13). Carbon dioxide levels were similar to previous years. There were no recorded exceedances of the MOE limit of 1.0% methane during the reporting period. Monitoring will continue to meet regulatory requirements and to determine if any trends develop.

Conclusions and Recommendations

Perimeter and foundation probe monitoring results for 2017 were in compliance with the MOE requirements. Methane was not detected. The data implies minimal risk of subsurface methane migration to adjacent properties or buildings. Quarterly monitoring should continue to meet regulatory requirements and to evaluate public health and safety risk.

Hartland Landfill – Landfill Gas Monitoring 2017 Annual Report Page 29

8.2 Surface Emissions and Hotspot Sampling

A program has been established to monitor fugitive emissions from Hartland landfill. Landfill gas can migrate to the atmosphere by advection and/or diffusion via soil pores, gaps and defective cover materials. Surface emissions monitoring is completed at Hartland to assess the effectiveness of the permanent and temporary closure systems in the Phase 1 and Phase 2 areas to:

• support health and safety measures in areas with high concentrations of landfill gas; • inform operational or capital upgrades to landfill gas and closure infrastructure, where degraded or insufficient cover exists; • to confirm the effectiveness of the Phase 1 permanent closure; • support optimal operation of the landfill gas well field by identifying hotspot areas, which may lead to oxygen intrusion, or areas where well vacuum may be increased; and • guide future determination of flux, if desired. Surface emissions monitoring is typically conducted in addition to lateral subsurface monitoring to assess the effectiveness of the LFG collection and controls. This method is a simple and low cost means to assess methane and non-methane. Results and findings are reported to Hartland staff and a map of hotspots is produced to help identify problem areas or system deficiencies.

Z-point locations change over time as closures occur, covers are placed, the location of the active face changes, and monitoring equipment is installed. The majority of Z-points are located at breaks or seams of cover systems and near side slopes in Phase 2 where gas collection is a challenge. The locations of all grid points and hotspots as of the end 2016 are shown in Figure 9.

At the end of 2017, there was a total of 22 Z-points identified. All, but 1 of these points were carried over from previous surveys. Hotspots have decreased significantly since the implementation of the LFGMP in 2012. The number of hotspots peaked at 37 in 2011 prior to the Phase 2, Cell 1 closure in 2011, as well as an increase in gas well installation density, as a result of implementation of the LFGMP.

Methodology

A 50-by-50-m grid of monitoring points has been developed over the surface of the landfill. These monitoring points have been programed into a Global Positioning System (GPS) unit to ensure a consistent sampling network for the measurement of fugitive LFG emissions.

Total Hydrocarbon (THC) levels, reported as methane, are measured at each grid point approximately 10 cm above the ground surface using a flame ionizing detector (FID). Hydrogen sulfide levels are measured simultaneously using a Jerome H2S Analyzer. The FID is set to alarm at THC levels of 100 ppm and higher. If at any point during the survey the FID alarm sounds, a more detailed search, between grid points, is conducted to determine the source. Any location that exceeds 1,000 ppm is logged as a hotspot (Z-point) and THC concentration and GPS coordinates are recorded. Any Z-points from previous surveys are also monitored. A Z-point is removed after 3 consecutive monitoring events yield THC results less than 1,000 ppm. Full monitoring methodology is included in Appendix E.

Results

A summary of the results is shown in Table 14, Table 15 and Figure 9. A historical summary of all Z-points is provided in Figure 10.

A total of 8 unique grid points were found to exceed 100 ppm THC in 2017, all clustered within the temporary closure area on the North West slope of Phase 2. There were no elevated hydrogen sulphide concentrations.

Conclusions and Recommendations

No hotspots were identified in Phase 1 indicating that the cover and gas collection system in the permanent closure is functioning. LFG continues to escape in unclosed portions of Phase 2 and along openings in the tarp of the northwest face temporary closure.

A review of the monitoring program was conducted in 2017 and recommended changes to the monitoring program based on a reassessment of operational and health and safety objectives. Changes will be implemented in 2018 and include the following:

• A reduction in sampling frequency to once per year (during the seasonal peak of gas production). • Removal of grid points over areas without permanent or temporary closure (e.g., Cell 3). • A shift in focus from inventorying/identifying all hot spots to focusing on locations that can be easily mitigated. • Regularly review the objectives of the surface emissions survey and assess the potential for future flux measurements to support methane emissions modelling.

8.3 Landfill Gas Speciation

Monitoring for volatile organic compounds is currently conducted once every 2 years to assess changes in gas composition over time. Composition changes can inform LFG infrastructure upgrades and capital plans for alternative utilization options. Sampling was completed in 2017 (see Table 16) and is scheduled again for 2019.

Gas speciation data from 2017 is consistent with previous years. Table 16 summarizes gas speciation results from 2017 with relevant WorkSafeBC exposure criteria. Historical data is included in Appendix F.

The data indicate that undiluted LFG exceeded the WorkSafeBC limits for methane, carbon dioxide, hydrogen sulfide, vinyl chloride and benzene. However, exposure to undiluted LFG is unlikely as fugitive emissions mix quickly with air. Ambient air sampling conducted in 1999 and 2001 indicated an average dilution factor greater than 100:1. To further protect worker health and safety, personal gas detectors are set to alarm at levels consistent with 100:1 dilution factor (0.5% or 5,000 ppm methane or 10% of the LEL).

In 2017, a post treatment sample was completed after the conditioning skid (refrigeration unit), primarily to evaluate siloxane removal (Section 7.3.1) prior utilization, but also to assess the reduction in other LFG constituents. On average, the majority of volatile/aromatic compounds were reduced by 30%. As expected, the flammable aliphatic compounds (methane, propane, butane, etc.) were not reduced through refrigeration treatment. Raw data is provided in Appendix F.

8.3.1 Siloxanes

In addition to routine speciation, siloxane sampling was completed in 2017, due to concerns over increased engine wear and silica buildup. Siloxanes are organosilicons, which are added to many personal care products and plastics. Combustion of siloxanes leads to the formation of silica micro-particulates on engine components, such as spark plugs, pistons, valves, sensors, etc., which can reduce engine life.

Current literature on siloxanes indicates that the manufacturer siloxane limits for Caterpillar internal combustion engines is 28 mg/m3. Both pre- and post-treatment levels are significantly below this level (10.43 mg/m3 and 6.92 mg/m3, respectively) and considerably lower than other landfills; however, siloxanes at any concentration may result in silica build up and engine damage. On average, current gas conditioning (chilling) appears to successfully reduce overall siloxane concentrations by 34% (Table 13). It is important

Hartland Landfill – Landfill Gas Monitoring 2017 Annual Report Page 37

to note that siloxane concentrations will vary greatly over time. In addition, effects of silica compounds on engine components will vary widely by site making it difficult to develop and apply standard industry practices to reduce silica build-up. More comprehensive sampling should be completed before any firm conclusions can be drawn.

Conclusions and Recommendations

Based on 2017 data, the concentrations of individual volatile organic compounds and other constituents are fairly consistent over time; however, as waste composition changes, regular monitoring should continue. All results should continue to be compared to early 1991-2001 baseline data, in order to determine whether any individual volatile organic compound has the potential to approach WorkSafeBC exposure limits. Sampling for volatile organic compounds in LFG should be conducted again in 2019.

Siloxane sampling indicates relatively low siloxane concentrations in landfill gas, particularly post-treatment. However, engine maintenance requirements, due to silica fouling, have been increasing. Sampling should continue on a routine basis in order to better understand trends and impacts on the generator.

9.0 MODELLING

LFG generation rates are typically estimated by a model. These models generally use variations of a first- order decay equation developed by the US Environmental Protection Agency.

9.1 Inputs

Under the BC Landfill Gas Management Regulation, the MOE requires the use of a specific LFG generation model developed by Conestoga-Rovers and Associates. Protocols require the gas generation model input begin at 1980 and run to the present for annual reporting of collection efficiency. The Scholl-Canyon model requires input of site-specific data, which is discussed below. The gas generation model is run on an annual basis with updated waste quantity and composition data to produce current gas generation rates for calculating collection efficiency.

The following input data are required to run the MOE LFG generation model:

• historical tonnage back to 1980 • waste quantity • waste composition (ratio of relatively inert, moderately decomposable and decomposable wastes in place) • methane generation rate factor • methane generation potential factor • water addition factor

The methane generation rates and estimates were calculated by using the annual tonnage amounts and the waste composition data from studies completed in 1990, 1996, 2001, 2005, 2010 and 2016, as well as the most recent quantifiable kitchen scraps diversion data/estimates. Detailed waste composition information is provided in Appendices A2a, A2b and A4. The waste composition data was compared to Appendix A of the Categorized Waste Types in the Landfill Gas Generation Assessment Procedure Guidance Document provided by the MOE, to determine the percentages of waste that are relatively inert, moderately decomposable and decomposable. Each of these categories has a different methane generation potential in the model, as shown in Table 19. In addition, local rainfall amounts are factored into the model.

9.2 Modelling: Outputs

Table 20 shows the estimated annual methane production for Hartland landfill. The years selected for the table coincide with the activation of the LFG collection system in 1998. Gas generation is predicted to have peaked due to the kitchen scraps ban and will slowly decline through to landfill closure.

10.0 CONCLUSIONS AND RECOMMENDATIONS

The following section presents the key findings and recommendations developed from reviewing the data collected from monitoring programs at the Hartland landfill.

GAS GENERATION

Hartland landfill generates greater than 1,000 tonnes of methane per year and is subject to the Landfill Gas Management Regulation. In 2016, the Hartland landfill is estimated to have generated 7,957 tonnes of methane or the equivalent of 64,173 tonnes CO2.

GAS COLLECTION AND UTILIZATION

In 2017, the gas extraction network consisted of 141 wells that captured an average of 1,102 scfm of LFG. In 2017, 22 new wells were activated and 5 new wells were installed. An additional 9 wells installed in 2016 are not ready for activation, but are being monitored for sufficient LFG production. Well field balancing was completed each month to optimize collection. It is recommended that well field monitoring and balancing continue at least monthly, as recommended by the Design Guidelines.

Target collection efficiency (75%) was expected by 2016, according to the LFGMP. At the end of 2017, the efficiency was 67.7%, which is within the expected ranges of the LFGMP (Figure 5). The CRD continues to follow the LFGMP design specifications for reaching 75% collection efficiency. However, some schedule and well installation delays have occurred as a result of overall waste quantity reductions and filling plan changes. A review of the LFGMP is planned.

MONITORING

Gas Speciation

In 2017, there were no significant changes in the composition of undiluted LFG. The data indicate that undiluted LFG exceeded the WorkSafeBC limits for methane, carbon dioxide, hydrogen sulfide, vinyl chloride and benzene. However, ambient dilution and the required use of personal gas detectors at the landfill greatly reduce the risk of exposure above WorkSafeBC limits.

Siloxane sampling was completed in 2017 due to concerns over increased engine wear and tear. Siloxane levels are below the engine manufacturer’s specifications; however, further sampling is required to better understand concentrations and trends.

Perimeter and Building Foundation Probes

No elevated methane readings were observed at any foundation or perimeter probes indicating little risk of lateral LFG migration. It is recommended that quarterly perimeter probe monitoring and quarterly building foundation probe monitoring continue.

Surface Emissions Air Monitoring

In 2017, 8 unique grid points were found to exceed 100 ppm THC. There was 1 new hotspot identified in August, and 4 hotspots discontinued in March. It is recommended that grid monitoring and hotspot monitoring be conducted 2 times per year and that hotspots be mitigated where possible.

Appendix D1 Subsurface Perimeter and Foundation Probe Monitoring Methodology

The following is the subsurface probe and foundation monitoring field methodology as outlined in Hartland Landfill Standard Operating Procedures (2012). All monitoring is completed with a LANDTEC Gas Analyzer and Extraction Monitor (GEM) 2000+. Prior to 2011, the GEM 500 model was used.

CALIBRATION

Prior to each monitoring event, the gas analyzer is calibrated using the calibration gases at Hartland. Prior to calibration, the gas monitor is set to Gas Analyzer (GA) mode for ambient measurements.

Methane and carbon dioxide gases are used to calibrate the methane and carbon dioxide sensors, and zero the oxygen sensor. Oxygen gas is used to calibrate the oxygen sensor and zero the methane sensor. All calibration values should be recorded on the field sheet.

MONITORING

Weather conditions, including barometric pressure, precipitation and temperature are recorded prior to commencing work.

The following monitoring procedure is followed for each gas probe:

1. Zero pressure. 2. Connect tubing to the gas sample port (ensure pump is off), open valve, wait until pressure reading stabilizes and record value. 3. Turn on pump and wait at least 200 seconds. 4. Watch for any methane or carbon dioxide spikes. 5. At the end of 200 seconds record the gas concentrations and any spikes on the field sheet. 6. Quickly navigate to the pressure screen and record the static pressure reading (this helps determine whether the screen is plugged/open, or water is covering the screen). 7. Disconnect the tubing from the sampling port and close the gas monitoring valve. 8. Open the water level monitoring port (not all wells will have a water level monitoring port). 9. Follow the same procedure (steps 1–8) for gas probe B. 10. Once monitoring for probe B is completed measure the water level for probe A, followed by probe B. 11. Before moving to the next station, ensure that all valves are closed.

At the end of the day, check gas levels using the calibration gas and record on the field sheet.

Appendix E1 Grid and Hot Spot Monitoring Methodology

The following is the grid sampling field methodology as outlined in Hartland Landfill Standard Operating Procedures (2012).

Monitoring usually takes 2 full days, beginning at 0730 hours and ending between 1600 and 1630. Prior to each monitoring day the gas analyzer must be calibrated using the calibration gases at Hartland. At the beginning of each field day the fuel cell for the Flame Ionization Detector (FID) is filled with hydrogen gas and the unit is warmed up for at least 30 minutes before calibration. Calibration is conducted with 2 methane span gases (currently 500 ppm and 14,990 ppm methane) as well as a zero gas to generate a proper calibration slope. After successful calibration, as pan check is done whereby the span gases are applied to the FID and the concentration is recorded on the calibration sheet. In addition, the Jerome sensor is regenerated at the beginning and end of each day to remove any residual hydrogen sulphide on the gold sensor.

The Jerome analyzer is factory calibrated and, therefore, doesn’t require field calibration. After regeneration, the instrument is turned on for 30 minutes before zeroing. Once it is zeroed, the zero filter is attached to the unit and a sample is taken.

MONITORING

There is an established walking pattern over the grid points and it denotes 2 distinct monitoring areas (Phase 1 and Phase 2/Active Face). These areas are monitored separately due to the distinct differences in gas concentrations, level of landfilling activity, and placement of litter fences. This results in acquisition of data from a similar area under similar environmental conditions, as monitoring typically takes 2 days. In each area, the grid points are traversed alphabetically (e.g., B1, B2, B3, B4, etc.) where physically possible. In some cases, litter fences, controlled waste trenches or active filling areas limit or restrict access resulting in deviation from the standard protocol. These deviations should be recorded on the field sheet.

Weather conditions dictate when this monitoring can be completed. The FID cannot operate in rainy conditions and monitoring should be delayed until 2 consecutive days of dry weather are predicted. In addition, high to moderate winds blow gases away from their origin and dilute gas concentrations. These conditions are not representative of typical landfill conditions and monitoring does not take place on these days.

The following procedure is used to collect methane and H2S readings at each grid point:

1. Place the hydrogen sulphide (H2S) analyzer on the ground then press the “Sample” button. 2. The second staff person should place the FID intake controller 4 inches from the ground surface for 30 seconds. 3. Once the H2S analyzer has reported a value (approximately 30 seconds), the methane value should be read from the FID and both values recorded on the field sheet. 4. The FID is programmed to alarm if methane levels exceed 100 ppm. If the alarm sounds while walking a traverse, staff must investigate the area for the source of elevated methane by means of a detailed 10-by-10 metre (m) grid. The 10-by-10 m grid should be traversed between all adjacent grid points. Obvious sources of methane include bird poles or a seam/edge of a temporary closure lining. 5. Once the source has been identified, record the source description, methane and H2S values as well as the location coordinates. This data represents a “hot spot” (>1,000 ppm of methane) or “Z-spot” (>12,500 ppm of methane), identified on Figures 5 and 6 as a red, or purple, ‘X’, respectively. 6. If an obvious source cannot be identified, the location and data/observations from the highest localized reading should be recorded. 7. Continue with this method until all grid points, background stations, and pre-existing Z-spots have been monitored. Pre-existing Z-spots can be removed from the monitoring list if methane levels are below 1,000 ppm for three consecutive monitoring events. 8. At the end of each field day a span check is completed on the FID and recorded on the field sheet.

Electricity Consumption (kWh)

Comments: (max 4000 characters)

Changes in emissions for non-useful biomass and electricity generation compared to 2016 as a result of significant generator downtime in 2016. Generator was fully operational in 2017, therefore emissions are higher compared to 2016 (the opposite is true for non-useful biomass combustion emissions in 2016 compared to 2017 as a result of less gas flared).

Additional Information: **

2017 Stationary Combustion Emissions are higher than the 2015 and 2016 reported emissions due to significant maintenance requirements in 2015/2016. In addition. in 2017, the generator was operational 11/12 months resulting in less flaring requirements and lower overall Waste Emissions.
