The South Coast Air Quality Management District (SCAQMD) held its third working ground meeting on June 15, 2017, for Proposed Rule 1410 – Hydrogen Fluoride Storage and Use at Petroleum Refineries. The proposed rule is a result of investigative hearings following an incident involving hydrogen fluoride at a refinery in the South Coast Basin. Hydrogen fluoride (HF) is used in the refinery process to make high-octane gasoline, and currently there are two refineries in the South Coast Basin that use HF in their process.

The SCAQMD staff have been meeting with these refineries to discuss modified hydrogen fluoride (MHF) and potential mitigation measures. Some of the potential control measures being discussed include HF detection systems, visual inspections, and active and passive mitigation systems. Examples of these mitigation measures include block valves and inventory control. The proposed rule is currently scheduled to be considered by the Governing Board consideration in December 2017.
