Concentration Limits
Revised March 6, 2002

Fill Soils

Ecowaste has established the following concentration limits for Residential and Industrial Grade Fill Soils. All limits are expressed as µg/g on a dry weight basis (µg/g = mg/kg or ppm).

For any elements or compounds not shown, the values given in the Contaminated Sites Regulation and subsequent amendments apply.

Waste Soils

Waste Soils accepted by Ecowaste must not be Special Wastes. Acceptable waste soil generally has a minimum number (1 - 3) of substances exceeding the Ecowaste Industrial Limit. The average for any substance is normally not more than twice the Ecowaste Industrial Limit, with no single value more than 5 or 10 times the Ecowaste Industrial Limit. These are guidelines only as the acceptance of any soil will be established by Ecowaste on site-by-site basis.

Waste soil containing remediable hydrocarbons will not be accepted until the hydrocarbon levels are reduced to below the Ecowaste Industrial Limit.

History of Revisions

March 3, 2002 - Arsenic reduced from 60 mg/kg to 20 mg/kg for both Residential and Industrial Grade Fill Soils based on Second Stage Amendments to Contaminated Sites Regulation

April 6, 2005 - changed reference from "Second Stage Amendment ... " to "subsequent amendments apply".

Arsenic a Special Waste at 100 ppm?
At one time, the now Ministry of Water, Land and Air Protection, based on an interpretation of the Transportation of Dangerous Goods Regulations as enacted under the Transportation of Dangerous Goods Act, considered that arsenic above 100 ppm was a Special Waste. The Ministry now consider that soil with arsenic will only be a Special Waste if it fails the TCLP at 2.5 mg/L as listed in Part 2, Appendix 4 of the Federal Clear Language TDG Regulation.
