1.0 Introduction This report is prepared in partial fulfillment of the requirements of regulation 359/09 with respect to the Class 3 anaerobic digester to be constructed at the property. The project will carry a nameplate of 500kW and is designed to be expanded in the future to 1MW. The project has received a FIT contract number F‐003038‐BIG‐211‐203.

2.0 Project Location The location of the proposed 500kW biogas plant is shown on the drawing in Appendix 1. The land required is currently part of the Zoo’s composting operation and will occupy an area of approximately 5,000 m2 (or 1.3 acres) of the site. The digester will replace the zoo’s current composting operation. It is located on the east side of Meadowvale Road, south of the access road to the former Beare Road land fill site and is described as Lot 4, Concession 3, Scarborough.

The point of common coupling for the grid connection is located at the northeast corner of Meadowvale Road and the Beare landfill access road, approximately 200 meters north of the project site. (GPS coordinates: 43o49’06.16”N, 79o10’23.76”W). Underground conduits were dug and encased in concrete from the new digester, along the existing access road to the connection point.

The site is located on an isolated peninsula of land located between wooded slopes down to Meadowvale Road on the west, a wooded area and hydro corridor in the valley to the south and the valley to the east. To the north is a vacant field used for overflow parking and further north are additional parking lots associated with the zoo.

3.0 Surrounding Land Uses The nearest structure is a restored brick farmhouse (Pearce House) located some 230m to the north east and is used as the Rouge Valley Conservation Centre. The nearest residential area is located 850 meters to the south west on the opposite side of Meadowvale Road. The nearest home is located some 400 meters to the southwest, west of Meadowvale Road. All potential noise and odour receptors are well removed from the site. There are no surface water bodies, rivers or slopes in the vicinity of the site. A small pond located within the compost area occurs as a result of poor local surface drainage. The existing compost site is surrounded by earthen berms some 2 meters high. Forested lands are located immediately to the east, south and west of the compost site. No construction is required outside of the bermed area and no impact on the wooded areas is expected.

4.0 Site Plan The site plan for the project is in Appendix 2. The principle elements of the site plan are:

• An containerized combined heat and power (CHP) engine • A control room; • A 16 meter diameter digester; • A 36 meter diameter digestate storage vessel with dual membrane biogas holder cover; • A manure storage shed for receipt of solid manure from the Zoo; • Two in-ground receiving tanks; • A pasteurization system; • A solids separator; • A power Transformer and underground line to grid connection point; • A flare; • Various pumps, valves, mixers, sensors, control system and other appurtenances required to operate the plant.

All buildings, structures, etc. required for the installation are shown on Appendix 2. No easements, etc. are required for the project. The only two areas on the site where emissions are discharged to the air are the silencer / exhaust and the flare.

There are no heritage resources or archeological resources within 125 meters of the site. The site is not within the Oak Ridges Moraine, the Niagara Escarpment Plan, or the Lake Simcoe watershed. The site is within the Protected Countryside of the Greenbelt Plan which permits renewable energy projects.

5.0 Biogas Plant Design 5.1 Input Menu The biogas plant is based on the following approximate input menu:

• Zoo manure solid 3,000 Tonnes per year (10 Tonnes per day) • Grocery store or other liquid food waste 12,000 Tonnes per year (60 Tonnes per day) • Fats, Oils Greases liquid 2,000 Tonnes per year (10 Tonnes per day)

5.2 Control / Engine Building The control building contains the following:

• A control room with all of the electronic components to operate and monitor the plant • Switchgear required to export electricity to the grid • A 25 kW backup generator with automatic transfer switch • A backup boiler located outside to supply heat in the event of a power grid failure

The engine is housed in a separate prefabricated metal structure and includes:

• Heat recovery system to heat the vessels with provision for the export of heat to a future greenhouse to be constructed to the north. • A 500 kW generator

The engine room will be constructed to meet provincial noise standards. As the nearest noise and odour receptor is 250 meters removed from the flare no odour or noise impact is expected. Please refer to the ESDM and Odour reports for information on noise and emission modelling.

5.3 Receiving Tank The receiving tanks are 2 m high and 9.6 m in diameter with a volume of 120 m3. The top of the vessels are equipped with a camlock connection to receive liquids and a stainless steel door which can be opened to permit end dumping of material. A return liquid line from the digester is also connected to this tank. The tank is heated and equipped with a chopper pump and high level sensor.

Miller Waste Systems Inc. 8050 Woodbine Ave Markham, Ontario L3R 2N8 Email: [email protected] Tel: 905-475-6356

5.4 Pasteurizer System Material requiring pasteurization will be heated to 70oC and held at that temperature for one hour. The pasteurizer consists of a tube-in-tube heat exchanger to heat the material and 3 holding tanks to hold and maintain a temperature of 70oC in the material for one hour. From the buffer tank the material will be pumped into the digester on a pre-programmed schedule. A small carbon filter can also be installed on the tank to handle displaced air when the tank is filled.

5.5 Digester The digester is constructed of reinforced concrete and has a concrete roof. It is 16 meters in diameter and 10 meters tall. Total volume is 2,010 m3; operating capacity is 1,900 m3. Design retention time is 41 days. It is insulated and metal clad and the floor is roughly 2 m below finished grade. Interior exposed concrete in the headspace is sealed with a gas-tight, cast in place membrane (or a spray-applied coating) to prevent corrosion. Structural drawings have been designed and stamped by a Professional Engineer and regular inspections during construction are required.

Biogas produced in the digester is collected within the headspace of the tank and directed to the biogas storage membrane above the digestate storage tank via a pipeline. The gas flows from the gas storage membrane through a cooling field before being consumed by the engine. Digestate is pumped out of the digester through the skimming system into the storage vessel, through the screw press separator, at the same rate that the material is pumped in. The retention time within the digester is 41 days.

5.6 Digestate Storage The digestate storage vessel is a 36 m diameter, 8 m tall circular reinforced concrete tank. The tank will have a dual membrane gas storage membrane to store biogas from the digester. The tank is equipped with piping for filling and emptying and mixers for agitation. Digestate storage volume is sufficient for approximately 180 days before it is field applied. Approximately 13,500 cubic meters of digestate will be produced per year (37.1 cubic meters per day).

Table2 of Regulation 359/09 requires a setback distance of 224 meters from the nearest odour / noise receptor to the nearest digestate storage tank. The measured distance between the proposed flare site and the Rouge Valley Conservation Centre is 250 meters. Odour and Noise studies have been conducted.

5.7 Solids Separation After the material leaves the digester, it passes through a screw press separator which separates the solid fraction from the liquid fraction. The liquid is pumped into the digestate storage. The solid fraction is separated out and stored in a container.

5.8 Flare The emergency flare is designed to efficiently burn the quantity of gas potentially produced by the biogas plant in the event of the engine being down. The flare is equipped with a flame arrester and starts automatically when the engine cannot consume the quantity of gas produced.

6.0 Operations 6.1 Start up When construction of the plant is complete, the digester will be filled with liquid dairy manure and heated to 38oC with a temporary boiler. The initial biogas will be unstable in both quality and quantity and will be flared. When biogas production stabilizes, the engine will be started and commissioning completed. Zoo manure and liquid grocery input will be fed through the pasteurizer system and slowly added to the digester while monitoring biological stability.

6.2 Material Receiving Solid zoo manure (on average approximately 14 cubic meters per day) will be delivered by truck 2 or 3 times per week. Liquid inputs (45 cubic meters per day) will be delivered by truck once or twice per day. Delivery tickets are left in the control room.

6.3 Operation While the operator can override the computer control system manually, the control system is designed to operate the plant automatically. Sensors and timers are used to start and stop equipment. All operations are recorded in the computer. In the event of a malfunction, an alarm signal will be registered and the operator notified automatically by telephone. In most cases the operator can adjust plant operation remotely by telephone or internet.

6.4 Daily Monitoring The plant operator is provided with a schedule of inspections and maintenance actions to be performed daily, weekly and monthly. Gas quality testing is undertaken on a daily basis. Initially samples of the digester material will be taken according to the technology provider’s recommendation and sent to a lab. As digester performance stabilizes the sampling frequency is decreased until it occurs monthly. Bicarbonate monitoring occurs automatically and is logged in the system.

6.5 Maintenance Preventative plant maintenance is carried out based on a pre-determined schedule. All moving parts are regularly greased and inspected. Engine maintenance is carried out under contract to the supplier.

6.6 Digestate Liquid digestate is removed by truck in the spring and fall of the year and spread on farmers’ fields. The material is pumped from the digestate storage vessels into tanker trucks and is hauled out (185 truckloads over the space of 6 weeks in the spring and again in the fall).

7.0 Effluent Management 7.1 Sewage As staff and visitors are not expected to be on site for any length of time, no washroom facilities are included in the project. Should the need arise a portable facility with contracted cleanout will be utilized.

7.2 Storm Water Management. Currently the surface of the site is a compacted clay liner that was put in place as part of the compost facility construction. As a result of this impervious layer, runoff from the site to the shallow pond in the northeast corner of the site is estimated at about 95%.

When construction is complete approximately 50% of the impervious site will remain. This area will be topsoiled and seeded which will improve water retention in the area. Approximately 20% of the remaining area will be covered with structures and 10% will be driveway. The remaining 20% of the area will be topsoiled and seeded. The existing pond in the northeast corner of the site will be retained after construction.

Miller Waste Systems Inc. 8050 Woodbine Ave Markham, Ontario L3R 2N8 Email: [email protected] Tel: 905-475-6356

The site will be properly graded, topsoiled and seeded thus increasing rainwater infiltration over the current compacted soil within the compost facility. Surface drainage will continue to be directed to the pond located in the northeasterly corner of the site. A strormwater management plan is included with the supporting documentation and was prepared by Fisher Engineering.

7.0 Negative Environment Effects Anaerobic Digestion has numerous positive environmental impacts, including:

• reduces greenhouse gases, • eliminates contaminated run off from the existing compost operation • removes organics in the waste steam from landfill sites • results in electricity and heat from a sustainable, non‐fossil fuel source • results in a digestate that is highly desirable as an organic fertilizer • eliminates odours from the manure composting operation. • most pathogens within the input stream are destroyed. • all weed seeds within the input stream are destroyed reducing reliance on harmful herbicides.

The potential negative effects (and the mitigation measures in place) of this project are:

Negative Performance Objective Mitigation Effect Noise from Meet Provincial Standard The engine room, heat dump radiator and the exhaust the engine stack will be designed in accordance with Provincial noise standards. Odour Meet Provincial Standard This is also demonstrated by the presence of the existing compost facility. Input tanks are closed to minimize the possibility of fugitive odour emissions. Digestate is largely odour free. Setback requirements and biogas storage permeability requirements are met. See also the odour study report. Engine Meet Provincial Standard The engine and flare emissions will be designed to meet emissions Provincial standards. See also the ESDM report. Spills None The potential for spills at the site are minimized by the design of the plant. Camlock connections ensure that the possibility of spillage is minimized. All tanks are of tie-less design to prevent leakage and are equipped with a monitoring system.

7

Miller Waste Systems Inc. 8050 Woodbine Ave Markham, Ontario L3R 2N8 Email: [email protected] Tel: 905-475-6356

Siltation None The site is surrounded by berms which will prevent control siltation and construction equipment from leaving the construction site. After construction is complete, the disturbed area is to be seeded to prevent erosion from occurring.

Neither the construction of the project nor its long term operation will have a negative effect on the surrounding environment. The surrounding woodlands will remain untouched. There are no archeological or heritage resources identified in the area. No ground water will be taken; roof water will be collected and used.

8.1 Monitoring The entire biogas facility is visually checked daily by the operator and any issues are documented and repaired as required. The facility operator is also provided with a cell phone that is directly connected to the facility alarm system. As a result the plant is monitored 24‐7 and any repairs required can usually be completed by telephone or internet connection.

The monitoring wells are inspected daily to ensure that no tank leakage is occurring. Should leakage be detected the identified tank and the associated monitoring well can immediately be pumped empty to permit repairs to be made. The incident will be recorded and MOE advised.

8.2 Communications During the construction of the project, the owner will appoint its representative to be the sole spokesperson for the organization and be responsible for all communication with respect to the construction of the project. The contractor’s representative will regularly communicate with the spokesperson with respect to the status of the construction. If there are issues that need to be communicated to a wider audience, the Zoo CEO will be advised and the communication strategy will be developed. Depending on the nature of the issue, communication will be undertaken with MOE and any other party that may have an interest.

A sign will be posted on site with the name and contact information for the owner’s representative and the contractor. In addition key emergency information such as fire, police, ambulance and spills centre will be on the sign. Any emergencies will be handled in accordance with the emergency plan developed by the contractor.

9.0 Financial Assurance Part of the input to the biogas plant will be grocery store waste. This material is non‐hazardous and consists of unmarketable fruit and vegetables. In addition the plant is designed to handle Fats, Oils and Greases (FOG) also originating from the grocery industry. The maximum amount of unpasteurized material that the plant is capable of storing on site is 250 cubic meters in the receiving tanks and pasteurizer. The 2018 price for removal and disposal of this material is quoted at $190 (2011 quote, adjusted for inflation) per cubic meter for a total of $47,500 plus 10% contingency for a total of $52,250.
