Rule 4311 controls emissions from flares used in the Valley at facilities such as, but not limited to, oil and gas production facilities, sewage treatment plants, waste incineration and petroleum refining operations. Under Rule 4311, flare operators are required to submit flare minimization plans, perform extensive monitoring and record keeping, submit reports of planned and unplanned flaring activities to the District, and meet petroleum refinery SO2 performance targets.
The Rule 4311 amendment adopted December 17, 2020 satisfies the District’s control measure commitments in the 2018 PM2.5 Plan and the 2016 Ozone Plan. The amendments to Rule 4311 are estimated to reduce NOx emissions from flaring in the Valley by 37.2%, PM2.5 by 19.4% and VOC by 30.4%. This will achieve 0.19 tons per day (tpd) of NOx emission reductions in 2024, as well as an estimated 0.03 tpd of PM2.5 and 0.39 tpd of VOCs.
