Hazardous waste: What’s so ‘Special’?. Mark Heggie Waste Policy Unit [email protected] Introduction. Regulatory framework What is it, how is it regulated and what are our duties/responsibilities Consigning Special Waste Differences within the UK Who wants to be a SWillionaire
SEPA has to:
Producer – Person who produces the waste hazardous waste
Consignor – Removes or transports the waste from the place where it is being held (this can also be the producer)
Carrier – Transports the waste between the premises of the consignor and the consignee
Consignee – Receives the waste for treatment, disposal or recovery at a suitably licensed or permitted facility e.g. treatment facility or landfill site.Definitions
B1 - Description of the waste to be collected hazardous waste
B2 - EWC code
B3 - Physical form of the waste
B4 - Colour(s) of the waste
B5 - Estimate of the total weight of the waste
B6 - List the components of the waste and the concentrations they are present in
B7 - Indicate the relevant hazard code(s)
B8 - How was the waste produced.Section B – Description of the waste
Classify the waste using WM2 and the EWC and assign the appropriate code(s) and hazard code(s)
Complete sections A&B and send the pre-notification (white) copy to the appropriate SEPA office
Complete Section D (and check that the carrier had completed Section C) before waste leaves the premises
Make sure at least 3 copies (yellow, pink and gold) travel with the waste stream to the Consignee
Consignee retains the pink and yellow copies, and returns the gold copy to the Carrier/Haulier
Consignee sends deposit copy (yellow) to SEPA
Step 1 - "Directive Waste" is any substance or object which the producer or the person in possession of it discards or intends or is required to discard. This forms the basic definition of waste in the UK.
Step 2 and 3 – under powers provided by the Special Waste Regulations the Scottish Government can determine the classification of a waste.
Step 4 – how is the waste listed on the EWC and what is it listed as? Is it an absolute, mirror or non-hazardous entry.
Step 5 – you should have enough information about the chemical substances in your waste to know if it is hazardous or not (e.g. from safety data sheets, or knowing how the waste was produced).
If not you may need to test the waste for hazardous properties (see Step 6b).
Step 6a- There are three ways to find out if the substances in a “mirror” entry waste are dangerous: The ASL, MSDS or reference books/internet (peer reviewed).
If none of the substances in the waste are classified as “dangerous substances”,
the waste will not be hazardous and the non-hazardous EWC code can be used.
Step 6b - If you do not know what is in the waste, you must still find out if the waste is hazardous or not. You may have to use consultants or your waste contractor to
help you make this determination.
If you do not have this information, you may have to arrange for the waste to be
tested (see WM2 Appendix C for test methods).
Step 7 - a waste will be hazardous if it contains a dangerous substance(s) with a concentration at or above the appropriate threshold; and/or a test shows a hazardous property and the appropriate classification H1 to H14 can be applied.
Waste A produced from a manufacturing process contains 10% of chemical X and 18% of chemical Y with the remainder being water.
Step 1 – Yes
Step 2 and 3 – there are no specific provision, under domestic legislation, relating to the waste
Step 4 – it is listed with a mirror entry on the EWC 2002
Step 5 – Chemical X is listed on the ASL and we have the safety data sheet for chemical Y, so the composition of the waste is known and we can move onto step 6a.
Step 6a – Chemical X classified as F; R11, Xn: R20/22; and Chemical Y is classified as Xi: R36, Xn: R21 and N: R50, 53.
Based on the classifications Waste A could display the hazardous properties H3 (Highly flammable/Flammable), H4 (Irritant), H5 (Harmful) and H14 (Ecotoxic) and tests are needed
Step 7 - The results of the tests show that the threshold concentrations for H5 (Harmful) and H14 (Ecotoxic) are exceeded. The waste is therefore hazardous.
