1. Waste Management Overview & Land Disposal Restrictions

2. 2 Regulatory Framework for Hazardous Waste – EPA & Regulation 347 Environmental Protection Act (EPA) provides the ministry with the authority to govern and make regulations pertaining to the management of wastes. Regulation 347 made under the authority of the EPA is the key regulation for wastes: 1.Defines waste types; 2.Provides a “cradle to grave” management system for the management of hazardous wastes; 3.Identifies wastes through a series of listings, characterized through tests or defined as hazardous and require special treatment; 4.Sets approval and administrative requirements for generators, carriers and receivers of hazardous waste; 5.Identifies treatment standards through the LDR program.

3. 3 Subject waste used to describe wastes to which the registration and manifest provisions of Regulation 347 apply. Liquid Industrial wastes are not hazardous but are liquid (slump test) and industrial waste. Hazardous wastes are either listed, characterized through tests or defined. Waste Liquid IndustrialHazardous Municipal (Solid Non-hazardous) Regulation 347 Waste Descriptions Subject waste (unless excluded)

4. 4 LDR Program Overview Key components of LDR program: Treatment standards; Notification and Reporting – GRR; Waste analysis requirements; Treatment standards phased-in; Exemptions and Variances; –SQG, MHSW, equivalent treatment, alternate treatment.

5. 5 Wastes not affected by LDR Program Non hazardous wastes Liquid industrial wastes Exempted wastes (e.g. agricultural wastes, recycled wastes) PCB wastes (>50 ppm) Biomedical wastes SQE wastes

6. 6 Waste Streams Subject to LDR Listed hazardous wastes: –These are specific wastes that are listed in a series of schedules in the regulation (e.g. industrial waste streams, hazardous and acute waste chemicals and severely toxic wastes); –Once treated, these listed wastes remain hazardous and can only be land disposed in a hazardous waste disposal facility. Characteristic hazardous wastes: –These include wastes that are defined as hazardous because they are ignitable, corrosive, reactive and leachate toxic. Tests for these characteristics are specified in the regulation; –Once the characteristic is removed and the waste is treated to the new standards, these wastes will no longer be considered hazardous and can be disposed of at either a hazardous or non- hazardous waste disposal facility.

7. 7 Hazardous Waste Subject to LDR Hazardous Waste Listed Waste Characteristic Waste Hazardous Industrial (Schedule 1 and 1.1) Acute Hazardous (Schedule 2 Part A) Hazardous Chemical (schedule 2 Part B) Severely Toxic (Schedule 3) Ignitable Corrosive Leachate Toxic Reactive

8. 8 LDR Treatment Standards The treatment standards are based on the treatment standards developed as part of the U.S. LDR treatment standards. Treatment standards have been incorporated in Schedules in Regulation 347: –Standards are either a numerical standard or a technology standard; –Numerical standards are based on bulk analysis or TCLP as identified.

9. 9 How Treatment Standards work for Listed Hazardous Waste as of December 31, 2009 Treatment standards for listed wastes: –Found in Schedules: 1 (Hazardous Industrial Waste), 2A (Acute Hazardous Waste Chemical), 2B (Hazardous Waste Chemical), and 3 (Severely Toxic Waste) of Reg. 347; –Each listed waste has identified regulated constituents; –Treat waste that are at or exceeds the standard for each constituent or by the treatment code specified; –Treated waste - disposed at a hazardous waste facility.

11. 11 How the Treatment Standards work for Characteristic Waste as of December 31, 2009 Treatment standards for characteristic waste found in Schedule 5: –Treat waste to remove characteristic; –Treat regulated constituents that exceed Schedule 6 (Note: not in effect until Dec. 31, 2009); –Includes provisions to deal with special situations (e.g. “best efforts”); –Fully treated waste can be disposed at a hazardous or non- hazardous waste facility. Listed wastes that are also characteristic (not identified in the listed standard) must meet both treatment standards and disposed of at a hazardous waste facility.

Is the hazardous waste number listed in Schedule 13 Treatment Standard will be listed in Schedules 1, 2A, or 2B using the same corresponding hazardous waste number Treatment Standard will be listed in Schedule 5 using the same corresponding hazardous waste number N Y No treatment required N N N YY

14. 14 Mixed Hazardous Wastes Mixed hazardous wastes are only subject to the LDR treatment standards as of December 31, 2009. What is a mixed hazardous waste: –A mixture of hazardous wastes having both a hazardous characterization that is found in Schedules 10, 11, 12 and 13 and a hazardous characterization that is not found in Schedules 10, 11, 12 and 13 (but found in Schedules 1, 2a, 2b, 3 and 5).

15. 15 Alternate Treatment Standards Alternate treatment standards set out in Regulation for: –Soils that exhibit a hazardous characteristic; –Debris that are listed or characteristic. Alternate standards provided to: –Address uniqueness of hazardous soils and debris; –Facilitate remediation of contaminated sites.

16. 16 LDR Requirements - Generator Generator is responsible for determining if a waste or residue from the treatment of that waste is to be land disposed. As the treatment standards take effect the generator is required to amend their GRR and determine if the completion of the LDR Notification part of the GRR (Part 2B) is needed. –Provides needed information to receivers about the waste. Changes to GRR must be made within 15 days of the phase in dates: –August 31, 2007 – treatment of wastes in Schedules 10 to 13; –December 31, 2009 – treatment of all listed and characteristic wastes; –2009 registration to require additional information for affected wastes. The generator’s notification is the LDR Notification - Part 2B in the most recent generator registration report (GRR) or any subsequent supplementary GRR. –Must be sent before or with the first shipment of waste to the receiver (only exception is the fully treated characteristic waste – simple statement).

17. 17 LDR Requirements - Receiver Notification: If required, generators must provide the receiver with the following information as outlined in S.84: –LDR notification – Part 2B in the most recent generator registration report (GRR) or any supplementary GRR; –Notification must be provided by the generator before or on the first shipment of waste to the receiver regardless if the waste is treated or not (Only exception is fully treated characteristic waste – only simple statement is required); –Required to amend their GRR and determine if the completion of the LDR Notification part of the GRR (Part 2B) is needed. If the receiver is a transfer and/or processing station, then the receiver becomes the generator and is now required to register the residue or waste and if required, forward the updated LDR notification to the next receiver. Mixing, Blending and Bulking: Need a CofA to mix, blend and/or bulk hazardous waste with any other waste or material during the transfer and at the receiving facility.

18. 18 LDR Requirements Notification & On-site Records Notification for Small Quantity Generators (SQG): –SQG not subject to LDR notification requirements in S.84 of Reg. 347; –Notification is provided through a certificate placed on the outside of the sealed container for land disposal (S.80 of Reg. 347). Generator’s site where waste is treated to meet the LDR standard shall develop and follow a written waste analysis plan to include (S.85): –Regular and detail chemical and physical testing of representative samples; –Frequency of testing; –Records of testing; –Maintain plan and records for a minimum of 2 years.
