Power plants and other industrial sites in parts of the U.S., including construction material producers, may soon face more stringent nitrogen oxide emissions requirements as part of a “good neighbor” plan proposed by the U.S. Environmental Protection Agency on March 11.

这proposed rulewould use a variety of regulatory strategies to reduce emissions of nitrogen oxide (NOx), a key component in the formation of ground-level ozone, which is known to have negative health and environmental impacts in areas downwind of the emission sources, often beyond state boundaries.

环保局表示,其规则将减少NOx emissi的提议ons from the power sector by 29% and from heavy industry by 15% across 26 states during the summer ozone season.

该提案呼吁修改和加强针对2023年25个州发电厂的国家环境空气质量标准的排放交易计划，并于2026年开始新的排放标准industrial sitesin 23 states that have a significant impact on downwind air quality. EPA says these steps will help states meet "good neighbor" requirements under the Clean Air Act (SEE MAP BELOW)

这proposed emissions limits would apply to sites involved in the production of construction materials such as cement, concrete and steel, as well as other products such as glass and paper, plus natural gas pipelines.

EPA估计，拟议的策略将在2026年预防约1,000例过早死亡，医院和急诊就诊，至少每年至少有很多。

EPA管理员迈克尔·里根（Michael Regan）在一份声明中说：“空气污染并没有停止在州线上。”“此步骤将帮助我们的州合作伙伴符合空气质量健康标准，挽救生命并改善美国各地受烟雾影响的社区的公共卫生。”

该计划将建立在现有计划的基础上，以促进NOX发射来源中排放控制的一致操作。EPA提议对大型燃煤工厂的每日排放率限制，“银行业”排放津贴的限制以及从2025年开始的排放预算的年度更新。

Alex Bond, deputy general counsel for climate and clean energy at the Edison Electric Institute, which represents the investor-owned electric company sector, said in a statement that the group was reviewing EPA’s proposal and would work with the agency on policy-making efforts.

“自1990年以来，美国电力部门已将其NOX排放量减少了88％，如今，我们国家的40％以上的电力来自清洁，无排放的资源，包括核能，水力发电，风能，风能和太阳能，”说。

Environmental advocates praised EPA’s move. Matthew Davis, senior director of government affairs at the League of Conservation Voters, called the plan a “strong proposal to cut smog pollution.”

他在一份声明中说：“当各州不履行其保护社区免受化石燃料燃料燃料和工业设施的责任时，这项常识性规则强调了EPA作为联邦支持者的重要作用。”“这一规则的巨大健康益处是一个重要的提醒，即我们必须迅速从破坏性，寿命变化的化石燃料转变为可再生能源的未来。”

EPA also announced proposed standards to reduce emissions fromheavy-duty vehiclesthis month.
