An application for a permit for a new gas distribution system installation shall include evidence, when required that a “Certificate of Public Convenience and Necessity” has been issued by the Illinois Commerce Commission. Gas pipelines when permitted on the rights of way of County highways shall be constructed, maintained, and operated in conformance with the Federal Code of the Office of Pipeline Safety Operations, Department of Transportation, Part 192 – Transportation of Natural and Other Gas by Pipeline. Minimum Federal Safety Standards, the Department’s “Standard Specifications for Road and Bridge Construction”, and the regulations contained in this policy.
Applications for gas pipeline permits shall state the proposed pipe size, design, construction class, and operating pressures.
(A) Parallel Gas Pipelines. Gas pipelines for transmission distribution, and service may be permitted parallel to the centerline of conventional County highways under the following conditions:
The installation shall be located as near as practicable to the right of way line and not more than eight (8) feet (2.4m) from and parallel to the right of way line.
The materials, construction methods, and other elements are in conformance with the provisions of Article I of this Chapter. Gas pipelines shall have minimum cover of thirty (30) inches (0.8m).
(B) Gas Pipeline Crossings. Gas pipelines for transmissions, distribution, and service may be permitted to cross conventional County highways under the following conditions:
Installation shall cross at or as near as practicable to a ninety (90) degree angle with the highway centerline.
Crossings over sixty (60) psig shall be installed by jacking or boring with vented encasement provided between the ditch lines or toes of slopes of the highway. The crossing may be installed using, tunneling with vented encasement but only when the installation is not possible by other means. The venting of the encasement shall extend within one (1) foot of the right of way line. Crossings may also be installed by the use of “moles”, “whip augers” or other approved methods which compress the earth to move the opening for pipe.
Installation by open trench shall be permitted only prior to roadway construction with vented encasement provided between ultimate ditch lines or toes of slopes.
Encasement will not be required for service crossings or others under sixty (60) psig.
For installations sixty (60) psig and over encasement may also be eliminated under the following conditions:
Extra heavy pipe is used with the understanding that such omission shall preclude future maintenance or repair.
Cathodic protection of the pipe is provided.
The locations of the crossing pipe for transmission and distribution lines shall be marked at the right of way line with markers that identify the utility and provide emergency telephone numbers. In urban areas, the markers for transmission and distribution lines may be eliminated as provided in current Federal regulations.
In built-up or expanding areas, frequent service crossing should be discouraged in favor of establishing distribution on both sides of the highway.
Gas pipeline crossings shall have a minimum cover of thirty (30) inches (0.8m) at all locations on right of way, including below design ditch elevation if ditch is higher than design elevation.
