Project HistoryProject History4

• Thornhill Landfill started in 1976, approaching capacity• Terrace Landfill started in 1950’s. Available property

essentially consumed• Both landfills have leachate discharging directly to

sensitive streams/rivers• Major environmental upgrades required to support long

term landfill facility (about 50 Ha area needed)• Operating two small landfills is inefficient because of

economy of scale• RDKS started search for new landfill in 1996• Forceman Ridge site determined to be best long term

location

Waste CompositionWaste Composition5

Waste generation

•Estimated at 1.0 tonnes/person/yr

•Provincial avg. 1.2 tonnes/person/yr

•Provincial avg. diversion rate is 40%

•Max. Diversion goals:

•30% as recyclables

•17% as organics

•47% total

Waste DiversionWaste Diversion

System designed to accommodate future waste diversion measures

• Conventional recyclables (scrap, tires, whitegoods)

• Printed Paper & Packaging (PPP) from residential and ICI sectors

• Organics (wood waste, yard and garden, food waste)

Total waste generation in GTA is about 20,000 tonnes/yr

• Organics diversion can divert up to 3,500 TPY

• Recycling efforts can divert 800 to 3,800 TPY

• Amount diverted will depend on participation levels and public commitment to diversion

Proposed Solid Waste Management PlanProposed Solid Waste Management Plan

7

• Focus on Sustainability and Environmental Protection

• New Integrated Transfer Station at Thornhill Landfill

• New State of the Art Sanitary Landfill at Forceman Ridge

• Optimized Transportation System

• Supports Increased Recycling 30% Recycling inc. EPR, Scrap, Etc., ~ 6,000 tonnes/year

• Organic Waste Diversion About 17% of total waste, ~ 3,500 tonnes/year

• Minimized Environmental Impacts Reduced Carbon Footprint, Advanced Leachate Treatment

7

Organic Diversion StrategyOrganic Diversion Strategy

8

• Will increase Landfill Lifespan by approximately 22 years

• Reduced Leachate Strength

• Will convert organic waste to useful compost that can be used on site (soil for phytoremediation, final cover, biocover) and offsite for landscaping and agricultural applications

• Postpones Landfill Gas Collection Regulatory Requirement 2053 vs. 2070

• GHG Offset Credit Opportunities

• Positive Social Impacts (jobs)

Transfer Station Pros and ConsTransfer Station Pros and Cons

• Allows for dramatically reduced opening hours at landfill (cost savings)

• Reduces haul times for Terrace garbage collection fleet

• Reduces haul distance for most self hauls

• Consolidates all public MSW operations at one site

• Reduces traffic making left turn at Onion Lake

ProsPros

Transfer Station Pros and ConsTransfer Station Pros and Cons

• Increased packer truck traffic through Thornhill. (about 8 packer trucks per day)

• Increased traffic on Old Lakelse Lake Road (JackpineFlats), about 2 transfer trailers per day

• Additional cost of double handling most waste material at transfer station

Forceman Ridge Landfill Forceman Ridge Landfill Organic Diversion OverviewOrganic Diversion Overview

• Organics Diversion recommended for yard and garden waste, clean wood waste and food waste.

• SHA recommend implementation of “Gore” composting system.

• Gore System independently confirmed by Konrad Fitchner• About 4,000 tonnes/year can be diverted from landfill if

program fully implemented.• 2 Ha pad is being reserved for organics management.• Compost can be used on-site for biocover, phytoremediation

area and closure.• Compost can be supplied for landscaping applications and

natural fertilizer.

MMBC Facility and Diversion of RecyclablesMMBC Facility and Diversion of Recyclables

• MMBC is responsible for managing printed paper and packaging (PPP) generated in residential sector.

• Diversion rate of 75% required (avg. over province)

• RDKS would like to partner with MMBC and other EPR programs to establish full service Depot in Terrace

• Golder estimates:• Residential Depot for Terrace and GTA 129 tonnes

• Depot plus residential curbside collection 794 tonnes

• Depot, Curbside, plus ICI recyclables 2,653 tonnes

• All above plus Camp recyclables 3,805 tonnes

SHA/RDKS Value AddedSHA/RDKS Value Added

• Reduced truck traffic to Forceman from 10+ vehicles to 2 to 3 transfer trailers/day hopefully eliminates need for $1 million left turn upgrade

• Roger’s “Haul-Around “ solution eliminates need for $500,000 regrade of Chist Ck. Road

• Transfer station allows significantly reduced hours of operationat Forceman, saving $90,000/year

• Transfer will reduce hauling costs by $83,000/year

• Revelstoke Grizzly ADC will conserve 4,000 m3 of air space annually, extending lifespan by 17 years

SHA / RDKS Value AddedSHA / RDKS Value Added

• Berm reduces footprint from 27 Ha to 15 Ha. Results in cost saving on liner and cap totalling about $16.8 million

• Diversion of organics increases landfill lifespan by 22 years and provides opportunity for GHG reduction credits
