Alternative fugitive emissions standards are provided for well sites and compressor stations in California, Colorado, Ohio, Pennsylvania, and Texas, and well sites in Utah. Exempts equipment at onshore oil and gas processing plants used for emergencies from monitoring if they are in service for less than 300 hours per year. The 2016 rule specifically stated that the source category defined to include transmission and storage contributed significantly to air pollution reasonably anticipated to endanger public health and welfare based on its SO2, VOC, and methane emissions. For more information about the chronology of these two rules rolling back methane emissions standards for new, modified, and reconstructed oil and gas sources visit our EPA VOC/Methane Standards Regulatory Rollback Tracker page. Case studies have been published to show that oil and gas industries can lessen their emissions of methane. In addition to eliminating emissions standards for the transmission and storage segments entirely, EPA also eliminated the standards for methane emissions from all segments of the oil and gas industry. On August 13, 2020, EPA released its final rules rolling back standards to control methane and VOC emissions from new oil and gas facilities. Thus, EPA’s choice to eliminate methane regulation for new and modified sources means eliminating its ability to impose similar emissions standards on existing oil and gas facilities. EPA argues the evaluation itself was inadequate because EPA had not established criteria by which to make such determinations, something it expects to do in a future rulemaking before proposing any new NSPS. It removes a segment of oil and gas operations from regulation, discontinues regulation of methane (with the effect of also eliminating the legal predicate for regulating existing sources), and establishes new interpretations of the Clean Air Act that seem designed to hamper future EPA efforts to promulgate emissions standards for other pollutants from a variety of industrial sectors. This rule responds to requests for reconsideration of fugitive emissions requirements at well sites and compressor stations, well site pneumatic pump standards, and the requirements for certification of closed vent systems (CVS) by a professional engineer. 111(b) of the Clean Air Act. The changes also re-interpret the Clean Air Act to attenuate EPA’s authority to set pollution control standards generally, setting back and complicating future efforts by EPA to regulate methane emissions from the oil and gas sector. Methane is also a greenhouse gas (GHG), so its presence in the atmosphere affects the earth’s temperature and climate system. EELP is also developing additional legal analysis on certain aspects of the EPA’s positions in this rulemaking. see Joe Goffman and Laura Bloomer’s related article, canceled its Information Collection Request, Executive Order on Promoting Energy Independence and Economic Growth, D.C. Eliminating the standards for methane also ignores the technology-forcing purpose of the CAA. methods for estimating methane emissions from incomplete combustion. During year 2019, about 360 million tons of methane were released globally through human activities, while natural sources contributed about 230 million tons. An official website of the United States government. This is especially true in developing countries where improved access to information and technical training would be beneficial to generating support for methane recovery projects. These New Source Performance Standards were issued pursuant to Sec. Globally, increased methane emissions are responsible for half of the observed rise in tropospheric ozone levels.

Poorly functioning energy markets and financially insolvent utilities and municipalities within many countries fail to provide the private sector with a climate that will attract their investment in projects to capture and utilize methane. Methane is a very powerful greenhouse gas, and studies indicate that methane emissions from the oil and gas industry are likely significantly higher than previously reported, indicating these estimates may undercount the impacts of the rule. GMI created a Methane Mitigation Matters video series Exit to explain the role of methane in climate change and provide an overview of the biogas, coal mine, and oil & gas sectors. EPA trades emissions reductions for a thinly supported legal theory restricting the agency’s regulatory authority. Revises the applicability criteria for the sulfur dioxide (SO2) standards to define sweetening units as any onshore sweetening unit that processes natural gas produced from either onshore or offshore wells, correcting the prior definition that only referred to those that processed gas produced at onshore wells. Coal mines, for example, seek to vent methane from the mine workings because it can cause explosions. The major methane emission sources for these countries vary greatly. Changes the rules around well completions so that a separator is no longer required to be on site during the entire flowback period. Anthropogenic emission sources include landfills, oil and natural gas systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial processes. Expands technical infeasibility exemptions from emissions control requirements to pneumatic pumps at all well sites, the prior rule only allowed for the technical infeasibility exemption at greenfield sites.
