Notice of Rule Proposal
Surface Water Quality Standards, N.J.A.C. 7:9B-1.4, 1.5(g) and 1.14(d)
Take notice that the NJ Department of Environmental Protection is proposing amendments to the Surface Water Quality Standards at N.J.A.C. 7:9B to amend the nutrient policy (N.J.A.C. 7:9B-1.5(g)), the nutrient/phosphorus criteria (N.J.A.C. 7:9B-1.14(d)), and the definition of watershed-specific translators (N.J.A.C. 7:9B-1.4).
The Department determined that the existing nutrient policies at N.J.A.C. 7:9B-1.5(g) could be applicable to all waters including saline estuarine (SE) and saline coastal (SC). The Department is proposing to recodify the provision from N.J.A.C. 7:9B-1.5(g)2 to N.J.A.C. 7:9B-1.14(d)4i as narrative nutrient criterion applicable to all stream classifications. As a result, the Department is proposing to recodify provisions currently at N.J.A.C. 7:9B-1.5(g)3, 4, and 5 to N.J.A.C. 7:9B-1.5(g)2, 3, and 4. The numeric phosphorus criteria of 0.1 mg/L for non-tidal streams and 0.05 mg/L phosphorus criteria for lakes, ponds and reservoirs are recodified at N.J.A.C. 7:9B-1.14(d)4ii(1) and (2). These numeric phosphorus criteria apply unless watershed-specific translators are established pursuant to proposed N.J.A.C. 7:9B-1.5(g)2 or if the Department determines that concentrations do not render the waters unsuitable for the existing or designated uses pursuant to N.J.A.C. 7:9B-1.14(d)4i.
Watershed-specific translators may be an alternative criterion or a combination of criteria. For example, a watershed-specific translator could be a variation of the existing phosphorus criteria, criteria established for a new parameter such as Chlorophyll a, or a combination of criteria for different parameters (for example, Chlorophyll a and dissolved oxygen). Watershed-specific translators are established to demonstrate compliance with the narrative criterion to protect existing or designated uses for a specified watershed. Watershed-specific translators may only be established as part of a TMDL evaluation pursuant to N.J.A.C. 7:15-6.3 to demonstrate compliance with the narrative criterion. The Department is proposing to amend the definition of watershed-specific translators to provide an accurate cross-reference to the proposed narrative criterion at N.J.A.C. 7:9B-1.14(d)4i.
The proposal is scheduled to be published in the New Jersey Register dated December 21, 2009. A courtesy copy of the proposal(PDF) is available from the Department’s web site. It may also be purchased from Lexis/Nexis at www.lexisnexis.com/bookstore.
