As a result ofthe inspection, ii appears that you have committed a probable violation ofthe Pipeline Safety Regulations, Title 49, Code of Federal Regulations. The items inspected and the probable violation(s) are: 1. S192.455 External corrosion control: Buried or submerged pipelines installed after July 31,1971. (a) Except as provided in paragraphs (b), (c), and (f) of this section, each buried or submerged pipeline installed after July 31, 1971, must be protected against external corrosion, including the following: (1) It must have an external protective coating meeting the requirements of s192.461. (2) It must have a cathodic protection system designed to protect the pipeline in accordance with this subpart, installed and placed in operation within 1 year after completion of construction, (b) An operator need not comply with paragraph (a) of this section, if the operator can demonstrate by tests, investigation, or experience in the area of applicationt including, as a minimum, soil resistivity measurements and tests for corrosion accelerating bacteria, that a corrosive environment does not exist. However, within 6 months after an installation made pursuant to the preceding sentence, the operator shall conduct tests, including pipe-to-soil potential measurements with respect to either a continuous reference electrode or an electrode using close spacing, not to exceed 20 feet (6 meters)' and soil resistivity measurements at potential profile peak locations, to adequately evaluate the potential profile along the entire pipeline. Ifthe tests made indicate that a corrosive condition exists, the pipeline must be cathodically protected in accordance with paragraph (a)(2) of this section, Examination of Norgasco's 6-inch diameter line segment between the Conoco-Phillips facility and your Pressure Reduction Station #1 revealed corrosion at the soil-air interface where the pipeline went under the road. The pipe surface was visibly corroded and needs to be evaluated and re-coated where necessary to meet the requirements of $ 192.461.
