Public Notice of Section 110(l) Demonstration  

  • Section 110(l) of the Clean Air Act (CAA) indicates that EPA cannot approve a state implementation plan (SIP) revision if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress, or any other applicable requirement of the CAA. When the SIP is revised, the Act requires that an analysis is conducted to verify that the SIP will not be relaxed in a way that would be impermissible under Section 110(l).

    The Utah Air Quality Board is proposing amendments to three SIP rules that trigger the 110(l) requirements. These include: Rule R307-343, Emissions Standards for Wood Furniture Manufacturing Operations; Rule R307-335, Degreasing and Solvent Cleaning Operations; and new Rule R307-304, Solvent Cleaning.

    Comments will be accepted by the Utah Division of Air Quality (DAQ) from July 1 to July 31, 2017. The 110(l) demonstration will be posted on the DAQ website at https://deq.utah.gov/NewsNotices/notices/air/Pubrule.htm.
