Section 16:25-8.7 - Appurtenances

1. Vent standpipes shall be located and constructed so as not to interfere with the maintenance of the highway or be concealed by vegetation. Vents should stand as close as possible to the right-of-way line and should not affect pedestrian traffic.

2. Drains shall not discharge into roadside ditches or natural watercourses.

3. Readily identifiable and suitable markers shall be placed on the right-of-way line where it is crossed by pipelines carrying transmittants that are flammable, corrosive, expansive, energized, or unstable, particularly if carried at high pressure or potential, except where a vent will serve as a marker. Markers are also required for longitudinal pipeline installations and shall be spaced at a distance which allows visibility between adjacent markers.

4. Manholes shall be designed and located in such a manner that will cause the least interference to other utilities and future highway expansion. New manholes shall not be located in the pavement of highways.

5. Shut-off valves, preferably automatic, shall be installed in lines at or near the ends of structures and near hazards, unless hazardous segments can be isolated by other sectionalizing devices within a reasonable distance.
