Rule 2201: New and Modified Stationary Source Review Rule

The San Joaquin Valley Air Pollution Control District (SJVACPD) is in the process of amending the New Source Review (NSR) requirements. The primary purpose of the revision is to adopt full federal offset requirements for nitrogen oxides (NOx) and volatile organic compounds (VOCs). The SJVAPCD has been requiring federal offset quantities since early 2022, when the District offset program failed to demonstrate equivalency with the federal requirements.

The proposed updates also include:

  • Public notification requirements for projects that increase the stationary source potential to emit (PTE) to ≥80% of the major source threshold for one or more pollutants; and
  • Modifications to the federal offset equivalency demonstration for particulate matter less than 10 and 2.5 microns in size (PM10 and PM2.5) and sulfur oxides (SOx).

Rule 2301: Emission Reduction Credit (ERC) Banking

Rule 2301 proposed amendments include:

  • Eliminating the ability to bank greenhouse gas (GHG) ERCs;
  • Clarifying the definition of “shutdown”; and
  • Allowing the SJVAPCD to use unbanked shutdown emission reductions in its offset equivalency demonstration.
