On October 22, 2015, EPA finalized revisions and confidentiality determinations for the petroleum and natural gas systems source category (40 C.F.R. 98, subpart W) under the Greenhouse Gas Reporting Rule. 80 Fed. Reg. 64,262. The final rule requires greenhouse gas emissions monitoring and reporting for several sources not previously included in subpart W. These sources include certain petroleum and natural gas gathering and boosting systems; transmission pipeline blowdowns between compressor stations; and completions and workovers of oil wells with hydraulic fracturing, under the existing Onshore Petroleum and Natural Gas Production industry segment. The final rule also requires reporting of certain well identification numbers for oil and gas wells. With respect to confidentiality determinations, EPA is requiring new data elements to be designated as “not CBI” (confidential business information), but does provide for delayed reporting in certain circumstances.
The revisions are effective January 1, 2016, and the first annual reports using the amended requirements will be those submitted March 31, 2017.
