As a result of the inspection, it is alleged that you have committed a probable violation of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items inspected and the probable violation is: 1. § 192.12 Underground natural gas storage facilities. (d) Each underground natural gas storage facility that uses a depleted hydrocarbon reservoir or an aquifer reservoir for gas storage, including those constructed not later than July 18, 2017 must meet the operations, maintenance, integrity demonstration and verification, monitoring, threat and hazard identification, assessment, remediation, site security, emergency response and preparedness, and recordkeeping requirements and recommendations of API RP 1171, sections 8, 9, 10, and 11 (incorporated by reference, see §192.7) by January 18, 2018.#

120191016W_Warning Letter_09132019_text.pdf, page 2CPF 1-2019-1016W DETI failed to monitor for the presence of annular gas as directed by API RP 1171, Section 9.3.2 on 46% of the wells in the field.
