The South Coast Air Quality Management District (SCAQMD) is proposing to amend Rule 1148.1 - Oil and Gas Production Wells, in order to reduce nuisance and potential exposure near sensitive receptors. Rule 1148.1 applies to onshore oil producing wells, well cellars, and produced gas handling operation and maintenance activities. The amended rule would strengthen the regulatory language, add odor prevention measures and monitoring, and set-up a tiered requirement system based on sensitive receptor proximity and how many odor complaints a facility has received in the past 12 months. The highest tier would require an Odor Mitigation Plan for sources within 1,500 feet of a sensitive receptor who have experienced five (5) confirmed odor complaints within prior 12 month, or received a Notice of Violation (NOV) for odor. The proposed amendment would also expand the definition of Sensitive Receptor by including residential homes along with K-12 schools, hospitals, daycare centers, and convalescent homes. By including residences as sensitive receptors plus adding new odor mitigation and other requirements, SCAQMD hopes to lessen the amount of odor complaints it receives from the operation of oil and gas production wells.

The SCAQMD has held two working group meetings regarding this amendment, and a public hearing will be held in quarter two of 2015.
