Comparison of EUB Directive 038-2007 to Other Energy-Industry Noise Standards
The Alberta Energy and Utilities Board (EUB) has issued one of the most comprehensive noise limit criteria in Directive 038, largely concerning the extensive oil and gas industry in Alberta. Along with the sound level criteria, addressed are the environmental surveying conditions, complaint investigation process and sound level prediction methodology. Several other jurisdictions have set criteria to limit the noise from oil- and gas-related operations, including the Colorado Oil and Gas Conservation Commission (COGCC), which recently voted to repeal their provision of a more stringent noise level criterion. Most of the criteria do not include limits on low-frequency noise unless such specific complaints have been made. Many regulations also give simplified criteria outlining A-weighted level limits at set distances from the source. Having a comprehensive set of criteria (such as in the EUB guidelines) gives the energy industry a more useful tool to proactively include noise mitigation in their environmental impact assessments. This paper will compare the noise limit criteria of several different jurisdictions including permissible sound levels, meteorological conditions, prediction modeling parameters and assumptions, measurement protocols and reporting requirements.
