In October, the New Jersey Department of Environmental Protection (“DEP”) proposed several amendments to two of its site remediation regulations, the Administrative Requirements for the Remediation of Contaminated Sites (the “ARRCs”) (N.J.A.C. 7:26C) and the Technical Requirements for Site Remediation (N.J.A.C. 7:26E).

There are three primary components to the proposed amendments. The first is to extend the Mandatory and Regulatory Timeframes established under the ARRCs, the second is to clarify the definition of a vapor intrusion immediate environmental concern (“IEC”), and the third addresses timing for receptor evaluation reporting. The proposed rule changes are subject to a 60-day public comment period that expires on December 3, 2010.
