Analytical Acceptance Criteria

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.




ARC Acceptance Criteria Matrix (see notes below)

Waste Type Required Testing Documentation
Virgin gasoline impacted soil generated from UST remedial activities regulated under 40 CFR 280 One sample per 500 tons:
(EPA Method 1311)Lead
Virgin gasoline impacted soil generated from an above-ground release or activities not regulated under 40 CFR 280 One sample per 500 tons:
(EPA Method 1311)Lead, Benzene
Virgin petroleum (non-gasoline) impacted soil generated from UST activities regulated under 40 CFR 280 One sample per 500 tons:
(EPA Method 1311 or SW-846) RCRA 8 Metals
Virgin petroleum (non-gasoline) impacted soil generated from an above-ground release or activities not regulated under 40 CFR 280 One sample per 500 tons:
(EPA Method 1311 or SW-846)RCRA 8 Metals
Waste-oil/non-virgin petroleum impacted soil generated from UST activities regulated under 40 CFR 280 One sample per 250 tons:
(EPA Method 1311 or SW-846) RCRA 8 Metals, PCB's, pH, Flashpoint, Reactivity, Volatile Organic Compounds (VOC's), Semi-Volatile Organic Compounds (SVOC's)
Waste-oil/non-virgin petroleum contaminated soil generated from an above-ground release or activities not regulated under 40 CFR 280 One sample per 250 tons:
(EPA Method 1311 or SW-846) RCRA 8 Metals, PCB's, pH, Flashpoint, Reactivity, Volatile Organic Compounds (VOC's), Semi-Volatile Organic Compounds (SVOC's)
Sandblast Grit One sample per 500 tons:
(EPA Method 1311)TCLP Lead. PCB testing may also be required depending upon the source.
Coal Ash One Sample per 200 tons:
(EPA Method 1311 or SW-846) TCLP RCRA 8 Metals & Vanadium

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

(*) Testing for Totals or TCLP is acceptable; further TCLP analysis may be required depending on data submitted. If a total analysis of the waste demonstrates that individual analytes are not present in the waste, or that they are present but at such low concentrations that the appropriate regulatory levels could not possibly be exceeded, the TCLP need not be run (40 CFR Part 261, Appendix II, Section 1.2). If the result of a totals analysis divided by the dilution factor exceeds the TCLP regulatory limit, full TCLP testing for the consitituent(s) in question is required.
