Comparison of Flare Requirements

Selected requirements in 40 CFR part 60, subpart Ja (as amended in 2012); South Coast Air Quality ManagemenRule 1118; and Bay Area Air Quality Management District (BAAQMD) Regulation 12, Rule 11 and Regulation 

Subpart Ja Requirements SCAQMD Requirements BAAQMD Re

§60.103a(a) Prepare and submit for 

approval a flare management plan that includes: 

1118 (d)(3) Prepare and submit only 

if performance targets are exceeded. But this is only to describe ways to minimize emissions.

§60.103a(a)(1)-(2) 

A listing of all refinery process units, producers of refinery fuel gas, and fuel gas systems connected to the flare and an assessment of whether discharges to affected flares from these process units and fuel gas systems can be minimized. 

1118 (c)(2)(A), (B), (C); 1118 (c)(3) 

Detailed PFDs of all upstream equipment and process units venting to the flare. Descriptions of procedures/equipment/ policies to reduce or eliminate flaring

§60.103a(a)(3) A detailed description of 

each affected flare; designation as either primary, secondary, emergency, or flare equipped with FGR system; for primary flares, methods for monitoring flow rate and sulfur content of gases; for secondary flares and flares equipped with FGR systems, 

1118(c)(2)(A) 1118(f)(3) 

A complete description and technical specifications for each flare and associated knock-out pots, surge drums, water seals and flare gas recovery systems; Flare monitoring and recording plan is very detailed and must be submitted regardless of whether there is an FMP
