WASHINGTON, D.C. The Department of the Interior and the Bureau of Ocean Energy Management have issued a final rule to update air quality regulations for applicable BOEM activities in the Central and Western Gulf of Mexico and offshore Alaskas North Slope Borough. <\/p>\n
The new rule does not relax any standards for regulating air quality, uses the best available science and makes important technical and compliance-related updates to bring the regulation into this century, the department said. <\/p>\n
The departments jurisdiction is limited to activities authorized under the OCS Lands Act in the Central and Western Gulf of Mexico and offshore the North Slope Borough of Alaska. The US Environmental Protection Agency (EPA) has air quality jurisdiction over all other parts of the OCS. It is also limited to regulating offshore emissions of criteria and their precursor pollutants to the extent they significantly affect the air quality of any state. With this clear mandate, the final rule operates within these parameters to improve air quality. <\/p>\n
The final rule provides a commonsense approach to ensure BOEMs Air Quality Regulatory Program remains in compliance with the OCS Lands Act requirements by ensuring that the bureau uses up-to-date air quality standards (i.e., National Ambient Air Quality Standards (NAAQS)) and benchmarks consistent with those already established by the EPA. <\/p>\n
Pursuant to Executive Order 13795 signed by President Trump and Secretarys Order 3350, BOEM reviewed its 2016 Proposed Rule on Air Quality Control, Reporting, and Compliance. As a result of this review and analysis of comments received on the proposed rule, BOEMs final rule adopts the following changes: <\/p>\n
Compliance with NAAQS. As was the case with the proposed rule, this final rule adds a definition of the NAAQS. It also clarifies that the departments reporting and compliance requirements apply to the emissions of all pollutants on the OCS for which a national ambient air quality standard has been defined. <\/p>\n
Updating significance levels (SLs). The final rule replaces the table of SLs in BOEMs existing regulations dating back to 1980 with a revised table, which is based on values set forth in EPAs regulations (40 CFR 165.51(b)(2)). BOEM will continue to update the table of SLs as appropriate, which will save operators from having to search for the SLs in EPAs regulations. <\/p>\n
New requirements for PM2.5 and PM10. This final rule replaces the former criteria air pollutant total suspended particulates (TSP) modeling requirements with new modeling requirements for the criteria pollutants particulate matter 10 (PM10) and particulate matter 2.5 (PM2.5). BOEM is also updating its forms to enable lessees and operators to identify, report, and evaluate PM2.5 and PM10 pollution in the air quality spreadsheets that they submit in connection with their exploration or development plans. <\/p>\n
Emissions exemption thresholds. The final rule also updates existing regulations that refer to emissions exemption thresholds to clarify that these formulas apply equally to development and production plans (DPPs) and development operations coordination documents (DOCDs). This update will not lead to a change in practice because BOEM has always applied its existing regulations on air quality to both DPPs and DOCDs. <\/p>\n
Clarifying terminology. The final rule updates various terminology to better clarify the intent of the regulations. For example, the final rule replaces the term air pollutant with the term criteria air pollutant. Under the OCS Lands Act, BOEM regulates the emissions of criteria air pollutants, since those represent pollutants for which the EPA has defined a NAAQS. BOEM regulates only those emissions that could affect the bureaus obligation to ensure compliance of state air quality with the NAAQS, so using the term air pollutant was not appropriate. <\/p>\n
Air quality spreadsheets. With the implementation of the new air quality rule, BOEM is also updating the Office of Management and Budget (OMB)-approved air quality spreadsheets, BOEM-0138 (for exploration plans) and BOEM-0139 (for DOCDs, and DPPs). The lessee or its designated operator must use these forms for proposed operations in areas of BOEM air quality regulatory jurisdiction. Concurrent with these changes, BOEM is phasing out its previous practice of including the emissions from transiting support vessels in the EET calculations, consistent with the bureaus statutory mandates. Air quality modeling will henceforth only be required in situations when a regulated facility, exclusive of support vessels, exceeds the relevant EET.<\/p>\n
