ADMINISTRATIVE REPORT. Organics Management Facilities Feasibility Study - For Information Only

Transcription

1 ADMINISTRATIVE REPORT TO: FROM: Environment and Infrastructure Committee B. Newell, Chief Administrative Officer DATE: March 2, 2017 RE: Organics Management Facilities Feasibility Study - For Information Only Purpose: To determine a location or locations for the development of facilities capable of diverting organic materials such as food waste from landfills. Reference: RDOS Webpage Organics Management Facilities Feasibility Study Business Plan Objective: Goal 3.3 To develop an environmentally sustainable region Objective By implementing the 2017 Phase of the Solid Waste Management Plan Background: The Regional District developed an organics strategy in 2010 which predicted the costs of developing a site capable of composting food waste generated from businesses, institutions and residents. The results were incorporated into the 2012 Solid Waste Management Plan. In 2013 the Regional District commenced an Organics Management Facilities Feasibility Study. A grant of $175,000 was received from the Federation of Canadian Municipalities to undertake this work. It was a three Phase project looking at the potential costs of enhancing and creating new local composting facilities: Phase 1: Cost of Composting at Publicly owned sites; Phase 2: Consultation with Private Sector to develop proposals for organic management facilities on private land; Phase 3: Obtaining costs and benefits for sending waste to potential private compost facilities, comparing public and private sector options and preparing a recommendation on how to proceed. The intent of the feasibility study was to provide information for a Triple Bottom Line analysis of cost, environmental considerations and social concerns.

2 Analysis: The attached Triple Bottom Line Analysis Memo details cost and environmental considerations but does not discuss potential social concerns. Public consultation is required for understanding and discussion around any social concerns. After the third pillar is complete, the full Triple Bottom Line Analysis will allow the Board to consider cost, environment and social factors prior to making a decision on location. Using four scenarios, the attached Memo ranks six parcels in terms of greenhouse gases, transportation costs, odour analysis and full life cycle costs. The results to date have provided the top two sites for locating a Regional compost facility. The facility would compost all commercial, institutional and residential food waste and yard waste, and potentially wastewater treatment sludge. One identified location is a portion of the property located at 2760 Marron Valley Road within the Penticton Indian Band. The Locatee owner has expressed interest in permitting the development of a compost site on this property. The site is within 1 km of Highway 3A. The other identified site is located on land owned by the District of Summerland adjacent to the Summerland Landfill. The parcel under consideration is north west of the landfill site along Princeton-Summerland Road. Table 1: Comparison of Potential Regional Compost Sites Marron Valley Rd Transportation Odour Weight Scale Green House Gases Best transportation site Up to 31 homes within potential annual odour impact area. No scales Better option due to lower transport distances Summerland Landfill $1-$2 extra per tonne. - Estimated between $45,000 and $93,000 per year. No homes located within the annual odour unit potential. Existing scale could provide savings of $1-$2 per tonne - $50,000 - $100,000 from both yearly staff time and capital Estimated extra 3-20 tonnes CO2 equivalents per year The feasibility study has indicated that it is more cost effective to have food waste and bio-solids on one site rather than separate locations. With the organics diversion, it has been estimated that between 3500 to 4000 tonnes of CO2 equivalents will be saved if it is not buried in the landfill. The estimated life cycle costs are similar for both sites; Summerland has an existing weigh scale but Marron Valley Rd site has less expensive transportation costs. Odour modelling for the Summerland Organics_Report_Mar2_2017.Docx File No: Development of Organics Infrastructure Page 2 of 3

3 site shows no impacts to local residents. Increased odour control may be required at Marron Valley site due to an odour potential during winter inversions. Communication Strategy: The results of the feasibility study discussing will be brought forward for public consultation to allow for an amendment of the Regional Solid Waste Management Plan. Next Steps: After public consultation, a recommendation will be presented to the Board to select the site that will move forward. A service area for the Regional compost site will be created to allow for the lease of land and the ability to enter into debt for construction of the facility as required. A timeline for completing these steps is Q3 of Respectfully submitted: Cameron Baughen Liisa Bloomfield C. Baughen, Solid Waste Management Coordinator L.

4 Organic Management Feasibility Study

5 RDOS Project History 2010 completed Organics Strategy Incorporated into 2012 Solid Waste Management Plan Feasibility Study Conducted with funding from Federation of Canadian Municipalities (FCM) Assessment 9 government properties Feasibility studies on 8 including odour modelling

6 RDOS Project History 9 private properties identified through RFP process 4 sites tied to specific technologies 5 sites total (public/private) chosen for further analysis Penticton AWWTP included as 6th Lifecycle costing of each site considered including transportation, compost marketing, GHGs, odour

7 Feasibility Study Results

8 Site Recommendation Site Hwy 3A Locatee Marron Valley Road Summerland Landfill Private Site 2 Oliver Landfill Campbell Mountain Landfill Penticton Advanced Waste Water Plant Recommendation Recommend public consultation for Regional compost site and residential food waste composting at facility. Recommend public consultation for Regional compost site and residential food waste composting at facility. Not recommended to proceed at this time. Recommend public consultation of residential food waste composting at facility. Potential for Penticton bio-solids compost operation. Not recommended to proceed at this time Marron Valley Rd shows best transportation, GHG and lifecycle costing Summerland Landfill has best odour regime and second best transportation, GHG and lifecycle costing

9 HWY 3A Locatee 2760 Marron Valley Road Locatee owners interested in leasing land Best transportation compost sites Better bulk compost price as near agriculturists Locatee lease to be developed PIB taxation agreement to be discussed Requires strict odour control as homes potentially affected

10 Summerland Landfill Best odour model Owned by Summerland 7 km of municipal roads to site (schools, residences) Average travel distance higher than Marron Valley Steep grades Summerland/Princeton Road. Potential for Regional site and residential food/yard waste from Summerland.

11 Oliver Landfill Good odour model as few homes Leased by RDOS Furthest site from population centroid of RDOS Need transfer station residential food waste from Penticton and Summerland raising costs Regional site Potential for taking residential food/yard waste from homes in Oliver, Osoyoos, Area A and C Commercial food waste would go to central facility

12 Campbell Mtn Landfill Potential for use of bio-solids compost for bio-cover Leased by RDOS Has limited space on site which will shrink as landfill develops bio-cover Could only handle biosolids, separate site needed for food waste Costs to run two separate compost sites for food scraps and bio-solids appears higher per tonne

13 Odour Modelling 1 odour unit just detectable by 50% of testers 5 odour units faint odour for most people 10 odour units distinct odour for most people

14 Odour Modelling Air moves generally uphill during day and downhill at night Follow flow of water bodies or cold air draws Winter time inversions trap odour Night time in winter most likely time to smell Less likely in summer; UV rays help destroy odour All locations require strict odour control but some further from homes Air filters will need to be well designed and odour control priority for site when receiving and turning piles Small sites generate little odour but increases with more materials received

15 Summerland Landfill Site Maximum OU for 10 minutes in 1 year Shows no current homes within 5 or 10 OU estimates

16 Location Buildings 10 OU Buildings 5 OU* Notes 2760 Marron Valley Rd All homes in mainly agricultural area Summerland Landfill 6 6 Only landfill buildings affected Private Site 2 (proposal) 0 0 As provided by proponent Private Site 2 (loss odour control) Potential if there is an extended breakdown Oliver Landfill 5 5 Some homes Campbell Mtn Homes and agricultural Landfill 5 14 buildings Osoyoos Landfill (Res Food Only) 2 3 No homes affected Maximum Predicted OU Over a Sustained 10-Minute Period within the Course of 1 Year; very sensitive analysis *5 OU includes all 10 OU properties Feasibility study based on low tech odour filters; conservative approach Private sector proposals show technologies and techniques to limit odour All sites will require rigorous odour control to proceed Turned windrow for just residential organics show good odour model

17 Results Technology Membrane Cover Enclosed Aerated In-Vessel In Vessel recommended to minimize odours (membrane cover and enclosed) Centralized site offers economies of scale over de-centralized (staff, scale, capital) Exact brand of technology not determined

18 Turned Windrow Potential for smaller communities (Oliver, Osoyoos, Summerland) for only residential food/yard waste! May reduce costs for residential collection and keep compost local Not viable to take commercial food waste! Commercial food scraps to central facility

19 Compare Price per Tonne Site (Waste) Estimated Cost Per Tonne Oliver Landfill (Oliver, Area C only) $157-$186 Summerland Landfill (Summerland only ) $134-$148 Princeton Landfill (Princeton, Area H only) $226-$246 Summerland Landfill (Full Regional) $65-$80 Summerland Landfill (Super Regional) $58-$78 Osoyoos Landfill Windrow (Residential Food/Yard Waste for Osoyoos, Area A only) $33-$59 Penticton AWWTP Anaerobic Digestion $327-$382 Smaller sites have higher costs as lower economies of scale Centralized site required for commercial food waste and most residential food waste In some areas residential food/yard waste composting with turned windrow to consider if saves money and provides local compost

20 Compost Fees ~$85 per tonne common for food waste (varies greatly by facility!) Lower than garbage ($95 to $110) Lower cost for just yard waste Additional costs for materials with higher contaminates Bio-solids charged higher rates due to low re-sale value of compost

21 Comparison Transportation Odour Hwy 3A Locatee - Marron Valley Rd Best transportation site. Mainly Provincial Highway to site. 14 homes within annual 10 odour unit potential. 31 homes within the annual 5 odour unit potential. Summerland Landfill Between $1-$2 extra per tonne. Estimated between $93,000 and $45,000 per year. Crosses 7 km of residential roads. No homes located within the annual odour unit potential. Weight Scale No scales Save $1-$2 per tonne if use landfill scale up to $100,000 from both yearly staff time and capital Green House Gases Better option due to transport Estimated extra 3-20 tonnes CO2 equivalents per year Both sites excellent locations. Marron Valley preferred for ease of transport. Summerland has fewer potential odour concerns but odour can be addressed with improved technology at Marron Valley site. Only Financial and Environmental concerns of Triple Bottom Line Require Public Consultation for Social aspects

22 Public Consultation Bring forward results to Public Consultation for Solid Waste Management Plan Amendment Neither site requires rezoning Newsletters, Ads, Open Houses, Council delegations End result: Informed decision from Board on preferred location of Regional compost site End result: Development of a Local Service Area establishment bylaw for construction of site with participating municipalities and electoral areas identified
