253.14—How do I determine the worst case oil-spill discharge volume?

(a) To calculate the amount of OSFR you must demonstrate for a facility under § 253.13(b), you must use the worst case oil-spill discharge volume that you determined under whichever of the following regulations applies:
(1) 30 CFR part 254 —Response Plans for Facilities Located Seaward of the Coast Line, except that the volume of the worst case oil-spill discharge for a well must be four times the uncontrolled flow volume that you estimate for the first 24 hours.
(2) 40 CFR part 112 —Oil Pollution Prevention; or
(3) 49 CFR part 194 —Response Plans for Onshore Oil Pipelines.
(b) If you are a designated applicant and you choose to demonstrate $150 million in OSFR, you are not required to determine any worst case oil-spill discharge volumes, since that is the maximum amount of OSFR required under this part.
