Current through Register Vol. 56, No. 6, March 18, 2024

(a) Gas distribution mains shall be installed with a cover of not less than 30 inches above the top of the pipe, except where:

1. Interference with other subsurface structures makes it impracticable to maintain this depth of cover;

2. Short length replacement sections of distribution mains require offsets that could result in the trapping of liquids; or

3. It is not practical to install the main with at least 30 inches of cover.

(b) If a gas distribution main is installed with less than 24 inches of cover in accordance with (a) above, the installed pipe shall be protected with shielding that conforms with gas industry standards, both in respect to material and manner of installation. No shielding shall be required for a gas distribution main with 24 to 30 inches of cover.

(c) Gas transmission pipelines shall be installed with a cover of at least 48 inches above the top of the pipe, except where interference with other subsurface structures makes it impracticable to maintain this depth of cover or where short length replacement sections require offsets that could result in the trapping of liquids. In such cases, if cover is less than 42 inches, shielding shall be installed that conforms with gas industry standards, both in respect to material and manner of installation.

(d) Whenever conditions permit, gas service lines shall be installed with a cover of not less than 18 inches above the top of the pipe, except where interference with other sub-surface structures or the insertion/lining of service lines makes it impracticable to maintain this depth of cover, or where short length replacement sections require offsets that could result in the trapping of liquids. In such cases, shielding shall be installed that conforms with gas industry standards, both in respect to material and manner of installation.
