New York Codes, Rules and Regulations › Title 16 - DEPARTMENT OF PUBLIC SERVICE › Chapter III - GAS UTILITIES › Subchapter C - Safety › Part 255 - Transmission And Distribution Of Gas › Transmission Pipeline Integrity Management › Section 255.935 - Preventive and mitigative measures to protect the high consequence areas

Current through Register Vol. 46, No. 28, July 10, 2024
(a) General
					 requirements. An operator must take additional measures beyond those already
					 required by this Part to prevent a pipeline failure and to mitigate the
					 consequences of a pipeline failure in a high consequence area. An operator must
					 base the additional measures on the threats the operator has identified to each
					 pipeline segment. (See section
					 255.917 
					 of this Part.) An operator must conduct, in accordance with one of the risk
					 assessment approaches in ASME/ANSI B31.8S (as described in section
					 10.3 
					 of this Title), section 5, a risk analysis of its pipeline to identify
					 additional measures to protect the high consequence area and enhance public
					 safety. Such additional measures include, but are not limited to, installing
					 automatic shut-off valves or remote control valves, installing computerized
					 monitoring and leak detection systems, replacing pipe segments with pipe of
					 heavier wall thickness, providing additional training to personnel on response
					 procedures, conducting drills with local emergency responders and implementing
					 additional inspection and maintenance programs.
(b) Third party damage and outside force
					 damage.
(1) Third party damage. An operator
					 must enhance its damage prevention program, as required under section
					 255.614 
					 of this Part, with respect to a covered segment to prevent and minimize the
					 consequences of a release due to third party damage. Enhanced measures to an
					 existing damage prevention program include, at a minimum:
(i) using qualified personnel (see section
					 255.915  of
					 this Part) for work an operator is conducting that could adversely affect the
					 integrity of a covered segment, such as marking, locating, and direct
					 supervision of known excavation work;
(ii) collecting in a central database
					 information that is location specific on excavation damage that occurs in
					 covered and non covered segments in the transmission system and the root cause
					 analysis to support identification of targeted additional preventative and
					 mitigative measures in the high consequence areas. This information must
					 include recognized damage that is not required to be reported as an incident
					 under sections
					 255.801(a)
					 and
					 255.831 
					 of this Part;
(iii) participating
					 in one-call systems in locations where covered segments are present;
(iv) monitoring of excavations conducted on
					 covered pipeline segments by pipeline personnel. If an operator finds physical
					 evidence of encroachment involving excavation that the operator did not monitor
					 near a covered segment, an operator must either excavate the area near the
					 encroachment or conduct an above ground survey using methods defined in NACE RP
					 0502 (as described in section
					 10.3 
					 of this Title). An operator must excavate, and remediate, in accordance with
					 ANSI/ASME B31.8S and section
					 255.933 
					 of this Part any indication of coating holidays or discontinuity warranting
					 direct examination.
