美国寻求限制公共土地钻探中的火炬燃烧和甲烷泄漏

该提案将对火炬燃烧设定每月限制,并要求石油和天然气公司在联邦土地上开展甲烷泄漏检测计划。

乔·拜登总统的政府于 11 月 28 日提出了旨在限制公共土地上石油和天然气钻探产生的甲烷泄漏的规则,这是华盛顿打击强效温室气体排放的最新举措。

该提案补充了美国政府已经为私人土地上的该行业提出的新规则。它将对火炬燃烧施加每月限制,并要求石油和天然气公司对联邦土地上的作业进行甲烷泄漏检测计划,美国近十分之一的石油和天然气生产都在联邦土地上进行,主要在西部各州。

美国土地管理局(BLM)表示,这些规定将有助于防止天然气浪费并提高纳税人的回报。

“这项规则草案是一个常识性的、对环境负责的解决方案,因为我们正在解决浪费天然气造成的损害,”美国土地管理局局长特雷西·斯通-曼宁(Tracy Stone-Manning)在一份声明中表示。

甲烷是天然气的主要成分,容易从钻井现场和管道泄漏到大气中。在 20 年的时间内,它的捕热能力比二氧化碳强约 80 倍。

内政部表示,几十年来,公共土地上生产的通风和燃烧活动显着增加。

燃烧或故意燃烧作为石油副产品产生的气体,将二氧化碳释放到大气中,同时排放释放未燃烧的甲烷。当石油钻探商缺乏将天然气运往市场的管道,或者价格太低而不值得运输时,他们往往会燃烧或排放天然气。

拟议的规则将要求每个钻探许可证申请人提交一份计划,详细说明如何最大限度地减少甲烷浪费。如果土地管理局发现该计划不充分,可能会推迟许可申请。

一个石油和天然气行业组织表示,联邦甲烷监管应由美国环保局负责,该机构一直在制定自己的规则。

“这个问题并不像这项规定看起来那么简单,因为排放和燃烧天然气的原因有很多,比如安全问题和连通性问题,”独立石油公司政府关系副总裁马洛里·米勒(Mallori Miller)美国协会在一封电子邮件中表示。“当然,只要有可能,在市场上捕获并销售商品始终符合生产者的最佳利益。”

新规定是在前总统巴拉克·奥巴马(Barack Obama)政府制定的甲烷法规多年的法律争论之后出台的。BLM 表示,其监管重点是废物预防,该领域拥有明确的法律权力。

实施这些规则每年将使石油和天然气公司花费约 1.22 亿美元,但每年将为他们带来 5500 万美元的回收天然气。据 BLM 称,这些天然气还将使每年支付给美国国库的特许权使用费收入增加 3900 万美元。

“石油和天然气公司没有理由浪费公共资源,更不用说像甲烷这样的强大温室气体了,”西方优先事项中心副主任亚伦·韦斯在一封电子邮件中表示。

US Seeks to Limit Flaring, Methane Leaks from Public Lands Drilling

The proposal would place monthly limits on flaring and require oil and gas companies to undertake methane leak detection programs on federal land.

President Joe Biden’s administration on Nov. 28 proposed rules aimed at limiting methane leaks from oil and gas drilling on public lands, Washington's latest move to crack down on emissions of the potent greenhouse gas.

The proposal complements new rules the U.S. government already proposed for the industry on private lands. It would place monthly limits on flaring and require oil and gas companies to undertake methane leak detection programs for operations on federal lands, where nearly a tenth of U.S. oil and natural gas production takes place, primarily in Western states.

The U.S. Bureau of Land Management (BLM) said the rules would help prevent gas from being wasted and boost taxpayer returns.

“This draft rule is a common-sense, environmentally responsible solution as we address the damage that wasted natural gas causes,” BLM Director Tracy Stone-Manning said in a statement.

Methane is the main component of natural gas and tends to leak into the atmosphere from drill sites and pipelines. It is about 80 times more powerful at trapping heat than carbon dioxide during a 20-year timeframe.

The Interior Department said venting and flaring activity from production on public lands has significantly increased over several decades.

Flaring, or deliberately burning gas produced as a byproduct to oil, releases carbon dioxide into the atmosphere, while venting releases unburned methane. Oil drillers tend to flare or vent gas when they lack pipelines to move it to market, or when prices are too low to make transporting it worthwhile.

The proposed rule would require each applicant for a drilling permit to submit a plan detailing how it would minimize methane waste. BLM could hold up the permit application if it finds the plan inadequate.

An oil and gas industry group said federal methane regulation should be handled by the EPA, which has been crafting its own rules.

“The issue is not as cut and dried as this regulation would make it seem as there are many reasons to vent and flare gas, such as safety concerns and connectivity issues,” Mallori Miller, vice president of government relations for the Independent Petroleum Association of America, said in an email. “Of course, it will always be in the best interest of a producer to capture and sell a commodity on the marketplace when at all possible.”

The new rules follow years of legal wrangling over methane regulations crafted by former President Barack Obama's administration. BLM said its regulation focused on waste prevention, an area over which it has clear legal authority.

The rules will cost oil and gas companies around $122 million per year to implement but will give them $55 million per year of recovered gas. That gas will also boost royalty revenues paid to U.S. coffers by $39 million per year, according to BLM.

“There’s no reason for oil and gas companies to waste a publicly owned resource, much less a powerful greenhouse gas like methane,” Aaron Weiss, deputy director of the Center for Western Priorities, said in an email.
