Current through Register Vol. 50, No. 6, June 20, 2024
A. Each operator shall maintain each valve
				  that is necessary for the safe operation of its pipeline systems in good
				  working order at all times. [
				  49 CFR
				  195.420(a)]
B. Each operator must, at least twice each
				  calendar year, but at intervals not exceeding
712
months,
				  inspect each valve to determine that it is functioning properly. Each
				  rupture-mitigation valve (RMV), as defined in §30105, or alternative equivalent
				  technology that is installed under
				  §30258.C or 30418, must
				  also be partially operated. Operators are not required to close the valve fully
				  during the drill; a minimum 25 percent valve closure is sufficient to
				  demonstrate compliance, unless the operator has operational information that
				  requires an additional closure percentage for maintaining reliability.
				  [49 CFR
				  195.420(b)]
C. Each operator shall provide protection for
				  each valve from unauthorized operation and from vandalism. [
				  49 CFR
				  195.420(c)]
D. For each remote-control valve (RCV)
				  installed in accordance with
				  §30258.C or 30418, an
				  operator must conduct a point-to-point verification between SCADA system
				  displays and the installed valves, sensors, and communications equipment, in
				  accordance with
				  §30446(c) and (e).
				  [49 CFR
				  195.420(d)]
E. For each alternative equivalent technology
				  installed under
				  §30258.C D, or 30418. A
				  that is manually or locally operated (i.e., not an RMV, as that term is defined
				  in §30105: [49 CFR
				  195.420(e)]
1. operators must achieve a response time of
				  30 minutes or less, as required by
				  §30419 B, through an initial drill and
				  through periodic validation as required by Subsection E.2 of this Section. An
				  operator must review each phase of the drill response and document the results
				  to validate the total response time, including the identification of a rupture,
				  and valve shut-off time as being less than or equal to 30 minutes after rupture
				  identification; [49 CFR
				  195.420(e)(1)]
2. within each pipeline system, and within
				  each operating or maintenance field work unit, operators must randomly select
				  an authorized rupture-mitigation alternative equivalent technology for an
				  annual 30-minute-total response time validation drill simulating worst-case
				  conditions for that location to ensure compliance with
				  §30419 Operators are not required to
				  close the alternative equivalent technology fully during the drill; a minimum
				  25 percent valve closure is sufficient to demonstrate compliance with the drill
				  requirements unless the operator has operational information that requires an
				  additional closure percentage for maintaining reliability. The response drill
				  must occur at least once each calendar year, at intervals not to exceed 15
				  months. Operators must include in their written procedures the method they use
				  to randomly select which alternative equivalent technology is tested in
				  accordance with this Paragraph; [49 CFR
				  195.420(e)(2)]
3. if the 30-minute-maximum response time
				  cannot be achieved in the drill, the operator must revise response efforts to
				  achieve compliance with
				  §30419 no later than 12 months after the
				  drill. Alternative valve shut-off measures must be in accordance with
				  Subsection F of this Section within seven days of the drill; [49 CFR
				  195.420(e)(3)]
4. based on the results of the response-time
				  drills, the operator must include lessons learned in: [49 CFR
				  195.420(e)(4)]
a. training and qualifications programs;
				  [49 CFR
				  195.420(e)(4)(i)]
b. design, construction, testing,
				  maintenance, operating, and emergency procedures manuals; and [49 CFR
				  195.402(e)(4)(ii)]
c. any other areas identified by the operator
				  as needing improvement. [49
				  CFR
				  195.402(e)(4)(ii)]
