Respondent owned and operated a Natural Gas Processing facility, which produces, processes, stores, or handles more than 10,000 pounds of a flammable mixture, including pentane, isobutate, isopentane, butane, propane, and ethane in the form of natural gas, natmal gas liquids, condensate, and/or crude oil. Pentane, isobutate, isopentane, butane, propane, and ethane are identified at 40 C.F.R. § 68.130 as regulated flammable substances with a threshold quantity of 10,000 pounds. On December 3, 2015 (“the day of the incident”), the Facility experienced a fire and secondary explosion as described below.
Special NOTE: Facility was cited because their HW permit did not require the “object to be worked on” be identified and a review of closed permits indicated the permits were vague and did not identify the objects upon which HW was performed
