As a result of the inspection, it is alleged that Denbury has committed a probable violation of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The item inspected and the probable violation is: 1. §195.202 Compliance with specifications or standards Each pipeline system must be constructed in accordance with comprehensive written specifications or standards that are consistent with the requirements of this part. Denbury failed to construct its pipeline system in accordance with written comprehensive specifications or standards consistent with Part 195. Specifically, Denbury failed to follow its Construction Standards, Below Grade Pipe Coatings, C1080 (Revised 2013-08-01), during the construction of its CCA Project. The procedures contain requirements to protect pipeline coating material during transportation, handling, and storage of pipe. Specifically, Section 2.4 states, “To prevent damage and loss of product, coating materials shall be transported, handled, and stored per Manufacturer’s recommendations. All coating material shall be stored in a clean, dry location and in a manner to protect them from contact with the ground and moisture. All coating material will be shielded from direct sunlight when not in use.” 2 During PHMSA’s inspection, pipes stored at the Alzada and Baker storage yards were heavily oxidized due to ultraviolet exposure. PHMSA’s review of the Material Test reports and Logistics Inspection reports indicated that the pipes were manufactured in 2019 and transported to the pipe storage yards by April 2020. The pipes at the storage yards were exposed to direct sunlight and moisture from April 2020 until the start of the project in July 2021. As a result of the inspection, PHMSA’s representative requested Denbury perform tests to ensure that the performance of the coating due to the failure to protect the pipe from exposure to direct sunlight as required by their specifications.
