From June 25-26, 2019, an authorized representative of the EPA conducted a compliance inspection of the subject facility (Respondent) to determine compliance with the Risk Management Plan (RMP) regulations promulgated at 40 CFR Part 68. In January 2017, Respondent failed to identify a hazard and properly implement a hot work permit procedure to ensure that fire blankets were available while a third-party contractor was performing welding. This caused a pin hole leak in a sensing pressure line, resulting in a fire. This was a violation of 40 CFR 68.85(b).
