AIR QUALITY PERMITTING ELEMENT

Bureau of Technical Services

The Bureau of Technical Services (BTS) has two operational units.  The Emission Measurement Section (EMS), located in a field office, oversees the testing of stationary source emissions in NJ.  Testing is done in two principle ways.  Periodic testing involves consultant firms taking discrete samples (once per quarter to once per lifetime) to determine the amount of air contaminants being emitted.  Continuous emission monitoring is conducted by having the analytical and recording equipment on the stacks, continuously obtaining emissions concentration information.  This group evaluates test protocols, observes testing, and reviews test reports to ensure the data submitted to the Department is valid.  They work closely with the permitting sections by providing technical analytical advice and also with the enforcement program by interpreting the data from testing.  Test data is also used for planning and rulemaking.

The other section, Air Quality Evaluation (AQE), uses computer models, stack emission limits, air monitoring data, and meteorological data to predict ground level concentrations of air contaminants from sources (mostly new and some existing sources).  The group also evaluates air quality modeling submitted by consultants as part of major permit applications for new and modified sources.  These assessments are used to insure the public is protected from increased long term cancer risk and acute health risks from air toxics.  The predicted ambient concentrations for federal criteria air containments are compared to National Ambient Air Quality Standards to insure no violations would occur.  They work closely with the two permit sections on determining the acceptability of proposed new and modified sources, as well as enforcement and other DEP programs on determining the air quality effects of sources in NJ.  Additionally, they coordinate the DAQ’s air toxics regulatory activities and maintain the inventory of air toxics emissions.
