[From Press Release] In response to a court deadline, the U.S. Environmental Protection Agency (EPA) has finalized standards to reduce harmful air pollution associated with oil and natural gas production. The updated standards, required by the Clean Air Act, were informed by the important feedback from a range of stakeholders including the public, public health groups, states and industry. As a result, the final standards reduce implementation costs while also ensuring they are achievable and can be met by relying on proven, cost-effective technologies as well as processes already in use at approximately half of the fractured natural gas wells in the United States. These technologies will not only reduce 95 percent of the harmful emissions from these wells that contribute to smog and lead to health impacts, they will also enable companies to collect additional natural gas that can be sold…
When natural gas is produced, some of the gas escapes the well and may not be captured by the producing company. These gases can pollute the air and as a result threaten public health. Consistent with states that have already put in place similar requirements, the updated EPA standards released today include the first federal air rules for natural gas wells that are hydraulically fractured, specifically requiring operators of new fractured natural gas wells to use cost-effective technologies and practices to capture natural gas that might otherwise escape the well, which can subsequently be sold…
Based on new data provided during the public comment period, the final rule establishes a phase-in period that will ensure emissions reduction technology is broadly available. During the first phase, until January 2015, owners and operators must either flare their emissions or use emissions reduction technology called “green completions,” technologies that are already widely deployed at wells. In 2015, all new fractured wells will be required to use green completions. The final rule does not require new federal permits. Instead, it sets clear standards and uses enhanced reporting to strengthen transparency and accountability, and ensure compliance, while establishing a consistent set of national standards to safeguard public health and the environment…
Thanks for sharing Important information. When natural gas is produced, some of the gas escapes the well and may not be captured by the producing company. These gases can pollute the air and as a result threaten public health. So necessary steps should be taken to control air pollution.
