Utah AQB Hearing for PM2.5 Non-Attainment SIP Amendments

The Utah Air Quality Board (AQB) held a public hearing on July 27 to discuss proposed new amendments to the Utah State Implementation Plan (SIP), which provides additional requirements to Utah's severe PM2.5 non-attainment areas. The Utah AQB stated that the majority of the new amendments utilized California SIP language as a template due to the comparability between the two states' PM2.5 non-attainment areas.

Stakeholder comments primarily focused on the following items:

  • Additional evaluation needed to determine the cost to industry associated with VOC emissions reductions (in $/ton VOC removed), as represented under proposed Utah Administrative Code (UAC) R307-304 (Solvent Cleaning).
  • Suggested establishment of a vapor pressure exemption for UAC R307-335 (Degreasing and Solvent Cleaning Operations) rule applicability.

The public comment period for Utah AQB's proposed new SIP amendments will continue through August 15 and are anticipated to be finalized on October 5. Additional information regarding the Utah AQB's proposed SIP amendments can be found here.
