Universal Citation: NJ Admin Code 16:25-8.5
Current through Register Vol. 56, No. 18, September 16, 2024
(a) Acceptable techniques for installing pipelines under a highway without disturbing the surface are subject to specific site conditions and include, but are not limited to, driving, jacking, boring, horizontal directional drilling, coring, and micro-tunneling.
(b) The design and trenchless construction of pipeline crossings under highways shall include the following:
1. The trenchless construction shall
extend a suitable distance beyond the slope or ditch lines. Where appropriate, the
trenchless construction shall extend to the access control lines, to the outside of
frontage roads, or to an indicated line that allows for future widening of the
highway without the need for any utility adjustment;
2. The portal limits of the pipeline crossings
shall be located beyond the surfaced areas of the highway to avoid impairing the
roadway during pipeline installation;
3.
The Department will establish, on a case-by-case basis, the need to grout the voids
outside the carrier.
(c) When trenchless installation is proposed by the utility, the utility shall furnish the Department with information regarding the construction methods, controls, and monitoring to be used.
