Section 7:1E-2.4 - In-facility pipes for hazardous substances

(a) Each in-facility pipe at a major facility containing a hazardous substance shall be sufficiently marked by lettering, color banding or color coding to enable facility personnel to identify any substance being leaked or discharged from an in-facility pipe.

(b) New buried piping installations shall have a product-sensitive leak detection device, where such devices are state-of-the-art, and shall be either double walled or have secondary containment or diversion systems designed and built pursuant to 7:1E-2.6.

(c) Existing buried pipes shall be either:

1. Equipped with product-sensitive leak detection devices, where such devices are state-of-the-art technology; or

2. Where state-of-the-art technology does not exist, inspected, repaired and maintained in accordance with API 570, incorporated herein by reference, or some other industry standard acceptable to the Department.

(d) If a section of buried pipe is exposed for any reason, the owner or operator shall ensure that it is carefully examined for deterioration, and if found to be deteriorated, shall be repaired or replaced. Existing pipes which require substantial reconstruction or replacement shall be upgraded to the standards applicable to new buried piping.

(e) Out-of-service pipes shall be capped or blank-flanged and marked as to origin, or physically removed.

(f) Pipe supports shall be designed so as to minimize abrasion and corrosion and allow for expansion and contraction.

(g) If in-facility pipes are elevated across roadways, gate check-in procedures, warning signs or other means shall be used to minimize the chance of a vehicular collision with the pipes.
