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 (CFR). The items inspected and the probable violations are: 1. § 195.420 Valve maintenance. (a) . . . . (b) Each operator shall, at intervals not exceeding 7 1/2 months, but at least twice each calendar year, inspect each mainline valve to determine that it is functioning properly. Seaport Midstream failed to inspect each mainline valve at intervals not exceeding 7½ months, but at least twice each calendar year, to determine that it is functioning properly.
