As a result of the inspection, it is alleged that you have committed probable violations of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations. The items inspected and the probable violation(s) are: 1. §192.12 (d) Underground natural gas storage facilities.

DEO had not requested pertinent well data from the operators of 3rd party wells within the buffer zone of the Chippewa and Gabor Wertz storage fields as required by API RP 1171, Section 9.3.1. API RP 1171, Section 9.3.1, states in part “The operator shall request well integrity evaluation CPF 1-2018-0007W data from third-party well owner/operators following the frequency established using conclusions from the risk assessment.” During the inspection at DEO’s office, DEO demonstrated that they had a template letter for requesting pertinent well data from operators of 3rd party wells.
