NJDEP Air Program Update – Industrial Stakeholders Group (ISG) Meeting September 7, 2018

The New Jersey Department of Environmental Protection’s (NJDEP) Air Permitting group held its quarterly Industrial Stakeholders Group (ISG) meeting on September 7, 2018 to provide an update to the regulated community on actions in progress.

General Permits (GP)/General Operating Permits (GOP)

GP-016A for Manufacturing and Material Handling Equipment is being updated to add one exclusion so that it is clear that the permit is not intended to cover fumigation operations. The permit currently excluded emissions of Hazardous Air Pollutants (HAPs) and was intended to exclude other air toxics, but this was not clear in the GP. The numbering system will not receive an update for this change; the permit will remain GP-016A.

The update of GP-13A for non-HAP Dry Cleaning is in web design and will be available by the end of 2018. An update is in process for the paper-only application for GP-015 covering Non-MACT Plating Operations. An update of GP-015 is anticipated to affect no more than twenty facilities in the state.

GP-009A covering larger boilers combusting gaseous fuels will be updated to be consistent with the recent updates of GP-017A and GP-018A. This update will allow facilities to enter a specific fuel usage limit and avoid artificial increases in potential emissions due to the current size bands offered from DEP.

DEP intends to update GP-019 (Portable Equipment), GP-021 (Combined Heat & Power) and GP-022 (CHP and RICE) to include the updated Subchapter 8 thresholds issued earlier in 2018. GP-007 (Storage Tanks) and GP-008 (Site Remediation) will also be updated at some point in the future.

Risk Screening

Significant changes are forthcoming to the risk screening process within New Jersey. The Risk Screening Worksheet was updated a second time in 2018. Additional changes were published on 8/30/18; the most current spreadsheet and associated guidance must be used moving forward for any source with a single stack. The Technical Manual update is nearly finished.

DEP has provided a new version of the Risk Screening Spreadsheet to some ISG members to verify its performance. This "future" version has been updated to include the newest
