Text Box: Compliance averaging is a means to determine compliance with Soil Cleanup Criteria by using the average contaminant concentration rather than the concentration of individual samples. Requirements for averaging are briefly described below. Can only be used after the completion of a Remedial Investigation. Samples with concentrations of total organic compounds > 10,000 ppm or Text Box: total VOCs > 1,000 ppm cannot be averaged. There is a limit for the maximum allowable concentration for individual samples. A multiplication factor determines the maximum. Some compounds cannot be averaged and some have more stringent compliance requirements. PCBs are handled differently because the cleanup criteria is for a total concentration not individual isomers. Text Box: Smaller areas of contamination are treated differently. The Technical Requirements for Site Remediation includes additional requirements for data usability. Text Box: the overall time frame for achieving groundwater standards was not considered. The appropriate place for consideration of such an alternative would have been in the feasibility study (FS). The FS for the site has already been completed Text Box: Picatinny Arsenal recently completed their response to comments from the USEPA and the NJDEP on the “draft” Area E Groundwater Proposed Plan. The USEPA questioned why a “more aggressive alternative” that treated a larger area and which would reduce Text Box: and was the subject of discussion at one or more technical meetings. A public meeting on the Area E Proposed Plan is anticipated for this coming June or July.

The Interstate Technology Regulatory Council (ITRC) offers training classes, both internet and classroom, and a wide variety of guidance documents. Their site address is http://itrcweb.org. Text Box: Another website of interest is that for the NJDEP. The NJDEP Site Remediation Program can be found on the web at http://nj.gov/dep/srp/. Look for guidance documents and general information. This site has links to the main site for the NJDEP and for the State. Text Box: The USEPA’s Technology Innovation Program offers internet training opportunities. The program’s CLU-IN internet studio offers a number of videos on site characterization and cleanup.
