Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part V - Hazardous Wastes and Hazardous Materials › Subpart 3 - Natural Resources › Chapter 302 - Transportation of Hazardous Liquids by Pipeline-Construction [49 CFR Part 195 Subpart D] › Section V-30260 - Valves: Location [49 CFR 195.260]

Current through Register Vol. 50, No. 6, June 20, 2024
A. A valve must be installed at each of the
				  following locations: [49 CFR
				  195.260]
1.
				  on the suction end and the discharge end of a pump station in a manner that
				  permits isolation of the pump station equipment in the event of an emergency;
				  [49 CFR
				  195.260(a)]
2. on each pipeline entering or leaving a
				  breakout storage tank area in a manner that permits isolation of the tank area
				  from other facilities; [49
				  CFR 195.260(b)]
3. on each pipeline at locations along the
				  pipeline system that will minimize or prevent safety risks, property damage, or
				  environmental harm from accidental hazardous liquid or carbon dioxide
				  discharges, as appropriate for onshore areas, offshore areas, and
				  high-consequence areas (HCA). For newly constructed or entirely replaced
				  onshore hazardous liquid or carbon dioxide pipeline segments, as that term is
				  defined at §30105, that are installed after April 10, 2023, valve spacing must
				  not exceed 15 miles for pipeline segments that could affect or are in HCAs, as
				  defined in §30450, and 20 miles for pipeline segments that could not affect
				  HCAs. Valves on pipeline segments that are located in HCAs or which could
				  affect HCAs must be installed at locations as determined by the operator's
				  process for identifying preventive and mitigative measures established pursuant
				  to §
												195.452(i)
				  and by using the selection process in Section I.B of Appendix C of Part 195,
				  but with a maximum distance that does not exceed 712 miles from the endpoints
				  of the HCA segment or the segment that could affect an HCA. An operator may
				  request an exemption from the compliance deadline requirements of this section
				  for valve installation at the specified valve spacing if it can demonstrate to
				  PHMSA, in accordance with the notification procedures in §30123, that those
				  compliance deadline requirements would be economically, technically, or
				  operationally infeasible. [49 CFR
				  195.260(c)]
4. on each lateral takeoff from a pipeline in
				  a manner that permits shutting off the lateral without interrupting the flow in
				  the trunk line; [49 CFR
				  195.260(d)]
5. on each side of a water crossing that is
				  more than 100 feet (30 meters) wide from high-water mark to high-water mark as
				  follows:[49 CFR
				  195.260(e)]
a. Valves must be installed at locations
				  outside of the 100-year flood plain or be equipped with actuators or other
				  control equipment that is installed so as not to be impacted by flood
				  conditions; and [49 CFR
				  195.260(e)(1)]
b. The maximum spacing interval between
				  valves that protect multiple adjacent water crossings cannot exceed 1 mile in
				  length; [49 CFR
				  195.260(e)(2)]
6. on each side of a reservoir
				  holding water for human consumption. [49 CFR
				  195.260(f)]
7. on each highly volatile liquid (HVL)
				  pipeline that is located in a high-population area or other populated area, as
				  defined in §30420, and that is constructed, or where 2 or more miles of pipe
				  have been replaced within any 5 contiguous miles within any 24-month period,
				  after April 10, 2023, with a maximum valve spacing
of 71/2
miles. The maximum valve spacing intervals may be increased by 1.25 times the
				  distance up to a 9 3/8-mile spacing, provided the operator: [49 CFR
				  195.260(g)]
a. submits for PHMSA review a notification
				  pursuant to
				  §30123 requesting alternative spacing
				  because installation of a valve at a particular location between a 7-mile to a
71/2-mile
spacing would be economically, technically, or
				  operationally infeasible, and that an alternative spacing would not adversely
				  impact safety; and [49 CFR
				  195.260(g)(1)]
b. keeps the records necessary to support
				  that determination for the useful life of the pipeline. [49 CFR
				  195.260(g)(2)]
