Sludge Quality Assurance Regulations Proposed for Readoption

by Anthony Pilawski
Bureau of Pretreatment and Residuals

The DEP recently proposed to readopt, with certain amendments and new rules, the Sludge Quality Assurance rules (SQAR) contained in Subchapter 4 of the Water Pollution Control Act. In addition, the proposal recodifies the SQAR into their own chapter at N.J.A.C. 7:14C. Published in the February 1, 1999 New Jersey Register, a public hearing on this rule proposal was held February 22, 1999.

The SQAR were initially promulgated in October 1979. Under the SQAR, the DEP embarked on a major program of monitoring the quality and quantity of sludge generated throughout the State by domestic and industrial treatment works. The SQAR information submitted by treatment works owners has been extremely useful to the DEP in evaluating sludge management plans, and to the generators in developing appropriate sludge management alternatives.

Under the rules, the DEP sets forth the sampling, analytical and reporting requirements for all domestic and industrial sludge generators. Changes are being proposed to 1) update analytical methods to be consistent with the Federal Rules at 40 CFR Part 503, 2) provide analytical exemptions for the smallest domestic treatment works (which typically service schools, religious institutions, and small commercial establishments), and (3) provide reductions for parameters which have not been frequently detected or which have been shown, through conservative risk assessments, to not pose a problem when managing sludge.

Comments on the proposed readoption and recodification with amendments may be submitted in writing until March 18, 1999 to:

Anyone desiring a copy of the proposed rules can access them from the division's web site at www.state.nj.us/dep/dwq. Questions regarding the proposal may be directed to the Bureau of Pretreatment and Residuals at (609) 633-3823.
