(1) Section 192.455(b) is supplemented by the following language after the first sentence: "Tests, investigation, or experience must be backed by documented proof to substantiate results and determinations." (2) Section 192.457 is supplemented: (A) by the following language in subsection (b)(3): "(3) Bare or coated distribution lines. The operator shall determine the areas of active corrosion by electrical survey, or where electrical survey is impractical, by the study of corrosion and leak history records, by leak detection survey, or by other effective means, documented by data substantiating results and determinations"; (B) by adding the following subsection: "(d) When a condition of active external corrosion is found, positive action must be taken to mitigate and control the effects of the corrosion. Schedules must be established for application of corrosion control. Monitoring effectiveness must be adequate to mitigate and control the effects of the corrosion prior to its becoming a public hazard or endangering public safety." (3) Section 192.465 is supplemented: (A) by the following language after the first sentence of subsection (a): "Test points (electrode locations) used when taking pipe-to-soil readings for determining cathodic protection shall be selected so as to give representative pipe-to-soil readings. Test points (electrode locations) over or near an anode or anodes shall not, by themselves, be considered representative readings"; (B) by the following subsection: "(f) When leak detection surveys are used to determine areas of active corrosion or re-evaluate unprotected pipelines, the survey frequency must be increased to monitor the corrosion rate and control the condition. The detection equipment used must have sensitivity adequate to detect gas concentration below the lower explosive limit and be suitable for such use." (4) Section 192.475(a) is supplemented by the following language at the end: "Corrosive gas" means a gas which, by chemical reaction with the pipe to which it is exposed, usually metal, produces a deterioration of the material."
