据OGJ10月15日报道称，美国环境保护署（EPA）提议修改2016年颁布的限制油气作业排放的法规。EPA在10月15日的联邦登记公告中称，具体而言，它正在重新考虑短时排放要求，井场气动泵标准，封闭通风系统认证要求以及排放限制规定的替代方法。
EPA还提出了额外的修正案，以澄清和简化规则的实施。这些包括完井（回流时的分离器位置，滤砂和线圈管清理），陆上天然气处理厂（资本支出和监测的定义），储存容器（最大平均日产量）和一般说明（官方认证和记录保存和报告）。
EPA表示，修改草案还包括对2016年6月3日发布的最终规则中因疏忽而产生的技术更正。它制定了温室气体排放的新污染源执行标准，对石油天然气作业产生的甲烷和挥发性有机物加以限制。
美国石油协会的一位官员对该机构的行动表示赞同。“EPA对联邦法规的技术修正对于确保相关法规反映当前的技术和运营是至关重要的。这些技术和操作正在继续减少甲烷排放，同时确保与该机构的法定权力保持一致，”API监管和科学事务高级主管霍华德费尔德曼说。

EPA proposes revisions in oil and gas operations’ emissions limits
The US Environmental Protection Agency proposed changes in regulations it issued in 2016 limiting emissions at oil and gas operations. Specifically, it is reconsidering fugitive emissions requirements, wellsite pneumatic pump standards, requirements for certification of closed vent systems, and the alternative means of emissions limitations provisions, EPA said in an Oct. 15 Federal Register notice.
EPA also proposed additional amendments to clarify and streamline the rule’s implementation. These include for well completions (location of a separator during flowback, screen-outs, and coil tubing cleanouts),The proposed revisions also included technical corrections of inadvertent errors in the final rule, which was issued An American Petroleum Institute official welcomed the agency’s action. “EPA’s technical corrections to federal regulations are essential to ensure that the respective rules reflect current technologies and operations that are continuing to reduce methane emissions while ensuring alignment to the statutory authority of the agency,” API Regulatory and Scientific Affairs Senior Director Howard Feldman said.
