This method of reassessment addresses the threats of external and internal corrosion. The operator must have conducted a baseline assessment of the covered segment in accordance with the requirements of sections 255.919 and 255.921 of this Part. An operator must take one of the following actions to address external corrosion on the low stress covered segment. (1) Cathodically protected pipe. To address the threat of external corrosion on cathodically protected pipe in a covered segment, an operator must perform an electrical survey (i.e., indirect examination tool/method) at least every seven years on the covered segment. An operator must use the results of each survey as part of an overall evaluation of the cathodic protection and corrosion threat for the covered segment. This evaluation must consider, at minimum, the leak repair and inspection records, corrosion monitoring records, exposed pipe inspection records, and the pipeline environment. (2) Unprotected pipe or cathodically protected pipe where electrical surveys are impractical. If an electrical survey is impractical on the covered segment an operator must: (i) conduct leakage surveys as required by section 255.706 of this Part, at four-month intervals; and (ii) every 18 months, identify and remediate areas of active corrosion by evaluating leak repair and inspection records, corrosion monitoring records, exposed pipe inspection records, and the pipeline environment. To address the threat of internal corrosion on a covered segment, an operator must: (1) conduct a gas analysis for corrosive agents at least once each calendar year; (2) conduct periodic testing of fluids removed from the segment. At least once each calendar year test the fluids removed from each storage field that may affect a covered segment; and (3) at least every seven years, integrate data from the analysis and testing required by paragraphs (1) and (2) of this subdivision with applicable internal corrosion leak records, incident reports, safety related condition reports, repair records, patrol records, exposed pipe reports, and test records, and define and implement appropriate remediation actions. ## Provenance - Official: Yes - Source: - Source ID: `ny-dps-nycrr` - SHA-256: `1ebe2430f664952ed877b24d42a91f96d40422ce0616c8bc991c7f73eba770b6` - Retrieved: 2026-08-12T06:20:40.894Z - Exported: 2026-08-24T00:24:08.005Z - Document slug: `ny-nycrr-255-941` ### Source metadata ```json { "jurisdiction": "US-NY", "title": 16, "part": "255", "partTitle": "Transmission and Distribution of Gas", "scopeKind": "gas-pipeline-safety", "tocPath": [ "Part 255 Transmission and Distribution of Gas", "Transmission Pipeline Integrity Management" ], "legalScope": "Complete current terminal legal unit exposed by the DPS-designated Title 16 NYCRR pipeline-safety part inventory.", "applicabilityCaveat": "Applicability depends on the part and section, Commission jurisdiction, commodity and facility type, intrastate or interstate status, operator and activity, exemptions, waivers, federal preemption, Commission orders, and incorporated law.
