The Ventura County Air Pollution Control District (VCAPCD) has proposed amendments to Rule 74.23, Stationary Gas Turbines. These amendments are part of the Best Available Retrofit Control Technology (BARCT) Rule Development Schedule in response to the passing of California Assembly Bill 617. The amendments aim to reduce emissions of oxides of nitrogen (NOx) and ammonia (NH3) from stationary gas turbines. The proposal changes the limits of NH3 to 5 ppm and NOx to 2.5 ppm. A public workshop to discuss the proposed amendments will take place on July 25, 2019 at the VCAPCD. The implementation deadline for these amendments is December 1, 2019.

Further information on the workshop details and proposed revisions can be found in VCAPD's Board Notice. For more details, please contact Danny McQuillan at (805) 645-1432 or via email at
