The South Coast Air Quality Management District (SCAQMD) has formed a Working Group and released Preliminary Draft Rule language for Proposed Rule 1118.1. The rule would restrict NOx, VOC, and CO emissions from flares at sources other than petroleum refineries and is focused on maximizing emission reductions, minimizing routine flaring, and encouraging beneficial use of gases that would otherwise be flared. Affected facilities will primarily include landfills, oil and gas production and distribution sites, and sewage treatment plants; the agency believes there are 265 flares in its jurisdiction that would be subject to the rule. According to the Preliminary Draft Rule, all new flares installed after the rule takes effect would be required to meet its emission limits.

Upon reaching 20 years of age, existing flares would be required to meet either the emission limits or the beneficial use targets. An estimated 36 flares could be replaced by 2023 with the current threshold approach. Alternative compliance options are being considered for sites that beneficially reuse most of their captured gas, use small flares with low overall emissions, and operate flares that operate less than 200 hours per year. All flares subject to the rule would be required to install a non-resettable, totalizing ultrasonic fuel meter. All flares required to comply with the emission limits would require testing to demonstrate compliance every third year. The Working Group has been evaluating new options that better address the cost-effectiveness of available emission reductions, and new Preliminary Draft language will be circulated soon.
