The Air Permitting Program is revising Technical Manual (TM) 1003, “Guidance on Risk Assessment for Air Contaminant Emissions.” The existing version of TM 1003 was issued in December, 1994. The revisions are necessary to outline current Department guidance, to reflect current Department procedures, such as an increased emphasis on risk screening procedures, and to update reference materials.

TM 1003 provides information for carrying out risk assessments for air toxics and for complying with risk guidelines.

TM 1003 is intended for source operations required to perform risk assessments for a Preconstruction Permit or Operating Permit, Permit renewal, or a Federal or State regulation. Regulations which could require that a risk assessment be performed include, but are not limited to, the following: N.J.A.C. 7:27, N.J.A.C. 7:26, Title 40, Code of Federal Regulations (CFR), Parts 60, 61, 63, 264, and 266.

A notice of the revision was published in the New Jersey Register on May 15, 2009. The public comment period will close on July 14, 2009. A revised manual and fact sheet are available at the Department’s web site: http://www.state.nj.us/dep/aqpp/publicnotices.htm
