Transcription

1 CCME Biosolids Task Group An Overview Benoit Lebeau Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) Compost Council of Canada September 23, 2010 Biosolids Task Group Canadian Council of Ministers of the Environment

2 Outline What is CCME - Biosolids Task Group Its mandate Work done to date Next Steps

3 Canadian Council of Ministers of the Environment (CCME) Council of Cabinet ministers Establish environmental priorities Program funded by annual dues from members Permanent secretariat Annual rotation of presidency 3

4 Biosolids Task Group - Genesis Formed in 2008 Anticipation that quantity of biosolids will increase with implementation of the Municipal Waste Water Effluent Strategy 4

5 Biosolids Task Group Made up of representatives from 14 federal/provincial/territorial jurisdictions Make decisions by consensus Co-chaired by BC and ON representatives 5

6 Desired Outcome Municipalities and biosolids generators manage biosolids under a harmonized national policy framework which instills public confidence and protects the environment and human health 6

7 Mandate Develop a Canada-wide approach for the management of wastewater biosolids focusing on policy harmonization 7

8 Work to date Legislative review GHG calculator (BEAM) Literature Review and Survey on Emerging substances of concern (ESoC) Drafted a Beneficial Use policy statement 8

9 Work Underway Guidance document Research clearinghouse 9

10 Legislative review Objectives: o outline the current regulatory framework o identify regulatory issues Based on: o responses to survey of federal and provincial representatives o review of federal/provincial guidelines Topics covered: o Legislative authority; Definitions; Approval process; Standards/Restrictions; Monitoring and compliance; Challenges

11 Wastewater sources/ Collection/ pretreatment Primary/secondary treatment Raw sludge/ Waste Activated Sludge Treatments (e.g. Conditioning/Dewatering/Drying) Effluent Biosolids Air Biosolids Storage and Transport Further processing: Pelletization; Composting Sale and Import of biosolids as fertilizers or supplements Post-sale/import: Use/disposal Land application Incineration Landfilling Fertilizers Act, Provincial Acts and Regulations Federal (not Fertilizers) Acts, Provincial, Territorial Acts and Regulations Legislative review

12 Legislative review Challenges Lack of clarity of roles and responsibilities Lack of consistency in definitions Different classifications

13 GHG calculator (BEAM) The Biosolids Emissions Assessment Model (BEAM) estimate GHG emissions, including establishing a baseline compare emissions from different biosolids management scenarios understand the factors that impact GHG emissions

14 GHG calculator (BEAM)

15 Emerging substances of concern (ESoC) Tasks Literature review of ESoC Identify ESoC in Canadian biosolids Survey and analyse Canadian biosolids for ESoC Assess process efficiencies in reducing ESoC Summarize BMP s for managing ESoC in biosolids

16 Emerging substances of concern (ESoC) Target analytes Neutral pharmaceuticals carbamazepine, trimethoprim, caffeine, cotinine Acidic pharmaceuticals acetaminophen, ibuprofen, gemfibrozil, naproxen Antibacterials triclosan, triclocarban Phenols - nonylphenol, octylphenol, bisphenol A Synthetic musk fragrances AHTN, HHCB, musk xylene, musk ketone Sulfa antibiotics - sulfamethoxazole, sulfapyridine

17 ESOC Survey Results some ESOC are not found in Canadian biosolids, other are found at low to very low concentration (nanograms per litre (10-9 g/l) or nanograms per gram (10-9 g/g)). Some ESOC show a decrease in concentration through treatment processes and in some cases to non-detectable concentrations. Among all treatments observed in this study composting appears to be the most efficient at removing several pharmaceutical and fragrance compounds.

18 Beneficial Use Policy Statement Define Beneficial uses Land Application Energy from residuals Guidance Document 18

19 Next Steps Consultation with stakeholders Consideration of consultation comments and completion of policy statement and guidance document Final submission to CCME in 2011 Research clearinghouse

20 Canada-wide Goals Canada-wide approach will indicate preferred options for biosolids management Factors considered: GHG emissions Residual's Quality Beneficial use opportunities 20
