NJDEP Proposes to Reclassify 749 Miles of Waterways to Highly Protected Antidegradation Status in First Such Move Since 2008

For the first time since 2008, the New Jersey Department of Environmental Protection (NJDEP) has proposed to amend its surface water quality standards to prohibit degradation of water quality in additional rivers and streams that did not previously enjoy such protection. The current proposal, which was released on March 4, would lift hundreds of miles of waterways to a more protected status as Category One waters. NJDEP’s water quality standards, found at N.J.A.C. 7:9B, have several components. The standards designate uses for all waters of the State, and prescribe water quality criteria (e.g., minimum levels of dissolved oxygen, and maximum levels of suspended solids and various toxics) necessary to allow for those uses. In addition, the standards establish three tiers of “antidegradation” designations. The highest tier consists of “outstanding natural resource waters,” so designated because of their unique ecological significance or because they are within the Pinelands, must be maintained in their natural state. Category One waters, occupying the second tier, are protected from any measurable change in their existing water quality. Water quality in Category Two waters, the third tier, may be lowered, but only with social and/or economic justification for the change. NJDEP’s proposal, which was first presented...
