18 AAC 75.370 - Soil storage and disposal

(a) Unless the department approves the activity in question as protective of human health, safety, and welfare, and of the environment, a responsible person may not blend contaminated soil with uncontaminated soil and shall

(1) segregate contaminated soil based on

(A) the intended cleanup alternatives; and

(B) the specific hazardous substance present;

(2) store contaminated soil

(A) 100 feet or more from surface water, a private water system, or a fresh water supply system that uses groundwater for a use designated in 18 AAC 70.020(a)(1)(A) and 18 AAC 70.050(2); and

(B) 200 feet or more from a water source serving a community water system, a non-transient non-community water system, or a transient noncommunity water system, as defined in 18 AAC 80.1990;

(3) place contaminated soil on a liner or on or within another impermeable surface that prevents soil and groundwater beneath the liner from becoming contaminated;

(4) place petroleum-contaminated soil on a liner that meets the minimum specifi cations for the testing methods set out in Table D of this section;

The ASTM International methods referred to in this table are adopted by reference. "N/A" means not applicable.

(5) place nonpetroleum contaminated soil on a liner compatible with the type of hazardous substance, and meet the general strength and thickness requirements of Table D;

(6) cover and protect the contaminated soil stockpile from weather with no less than a six-mil, reinforced polyethylene liner or its equivalent, with the edge of the cover lapped over the bottom liner to prevent water running through the soil; and

(7) inspect and maintain the contaminated soil stockpile regularly to ensure that the cover remains intact and that the soil and any liquid leachate derived from the soil is contained.

(b) A responsible person shall obtain approval before moving or disposing of soil subject to the site cleanup rules.
