Section 80. Procedures for estimating the probability of a discharge

The assessment shall provide an analysis of the probabilities of accidental discharges of oil, condensate, natural gas, and waste from gas, oil or geophysical operations or liquids being released into the environment during drilling, production, and transportation due to well blowout, equipment failure, transportation accidents and other reasons. Such an analysis shall include calculations based upon generally accepted engineering failure analysis procedures. An applicant shall calculate a spill probability analysis for three sizes of discharge events -- minor, moderate, or major. The applicant shall define the categories of minor, moderate or major discharge and describe the sources of information used to formulate the analyses and the assumptions used to construct the analyses. Discharge probability analyses for minor discharges should include calculations for a discharge that would not be expected to escape the operations area.
