Aggregate Recycling Corporation

ARC's waste characterization requirements are as licensed by Maine Department of Environmental Protection and in accordance with USEPA regulations.

ARC utilizes emulsified asphalt stabilization, processing materials through a cold-mix asphalt batch plant. Processing begins by sizing all materials through a fingerdeck screen, which eliminates non-aggregate products as well as oversized stone for subsequent crushing to meet sizing requirements. Screened material is conveyed to the feed system of the pugmill plant. Material is processed through the plant utilizing specially formulated emulsified asphalt, Recycling Agent, which stabilizes the aggregate.

The first step in qualifying materials for acceptance at ARC's facility is to determine the waste characterization, the required testing and necessary documentation. Below is a table with all the pertinent information.

(1) Testing requirements may be waived for virgin petroleum contaminated soils accompanied by a Maine DEP spill letter.

(2) If TOX > 1000ppm, Volatiles & Semi-volatiles testing is required. Volatiles & Semi-volatiles may be substituted for TOX with certain compounds required.

(3) If TOX > 1000ppm, Volatiles & Semi-volatiles testing is required. Volatiles & Semi-volatiles may be substituted for TOX with certain compounds required.
