Code of Federal Regulations Title 30. Mineral Resources § 30.250.1164 What are the requirements for flaring or venting gas containing H 2 S?

(1) For safety or air pollution prevention purposes, the Regional Supervisor may further restrict the flaring of gas containing H₂S. The Regional Supervisor will use information provided in the lessee's H₂S Contingency Plan (§ 250.490(f)), Exploration Plan, DPP, DOCD submitted to BOEM, and associated documents to determine the need for restrictions;  and

(2) If the Regional Supervisor determines that flaring at a facility or group of facilities may significantly affect the air quality of an onshore area, the Regional Supervisor may require you to conduct an air quality modeling analysis, under 30 CFR 550.303, to determine the potential effect of facility emissions. The Regional Supervisor may require monitoring and reporting, or may restrict or prohibit flaring, under 30 CFR 550.303 and 30 CFR 550.304.

(1) The volume and duration of each flaring and venting occurrence;

(2) H₂S concentration in the flared or vented gas;  and

(3) The calculated amount of SO₂ emitted.
