All gathering lines shall be buried beneath the surface wherever no blasting is required, and shall be steel or weather resistant black plastic wherever outcropping, resistant rock makes it necessary to lay the pipe on top of the ground. Lines crossing streams, rivers, intermittent streams or other drainways shall be constructed in such a fashion as to bridge the drainage features and protect the gathering lines from damage due to lack of adequate support. Failure of support may result in rupture of or discharge from the line. If the line is to be installed below the stream bed or below ground level and shall cross state waters an Aquatic Resources Alteration Permit shall be obtained prior to the activity occurring. Burial is not required, however, in those instances where this would conflict with the Natural Gas Pipeline Safety Act and rules at 40 CFR Part 192.
