POLICY TO CLARIFY NOISE CONTROL REGULATIONS

IN ACCORDANCE WITH RULE 802

(EFFECTIVE SEPTEMBER 20, 2004)

As specified in Rule 802.a., any operation involving pipeline or gas facility installation or maintenance, the use of a drilling rig, completion rig, workover rig, or stimulation shall be in compliance with the maximum permissible noise level for industrial zones. The industrial zone noise level shall apply for these types of operations at any location where the noise levels are measured.

If an oil and gas operation is located on the same property as an occupied building unit, the operation shall be in compliance with the maximum permissible noise level for residential zones. The noise level shall be measured at the occupied building unit as near as practicable to the exterior edge of the occupied building unit closest to the operation radiating the noise.

If the noise source is located on a separate property, sound levels shall be measured as follows:

a) On property located within a county approved platted subdivision:

1) Sound levels taken anywhere on a lot without a residence [as described in Rule 802.a.(1)] shall meet light industrial noise standards.

2) Sound levels taken anywhere on a lot with a residence [as described in Rule 802.a.(1)] shall meet residential noise standards.

b) On property not located within a county approved platted subdivision:

1) Sound levels taken twenty-five (25) feet from a property line [as described in Rule 802.a.(1)] shall meet light industrial noise standards.

2) Sound levels taken at a residence [as described in Rule 802.a.(1)] shall meet residential noise standards.

If the COGCC staff, after investigating a noise complaint decides not to issue a Notice of Alleged Violation, a complainant may file an application with the Commission requesting an Order Finding Violation hearing as specified in Rule 522.a(4).
