This meant that even if the facility reduces its emissions to below the major source threshold, either by controls or reductions in operations, it would still be subject to the major source rules. This is important since requirements for control equipment or procedures and numerous monitoring, recording and reporting obligations are based around this classification.<\/p>\n<p><a class=\"btn

seems to be relatively simple and straightforward and would be consistent with the concepts of thresholds in the Clean Air Act. Environmentalists and some states are opposed to the rule because they say there would be increases of thousands of tons of hazardous air pollutants. This suggests that as a result of this rule, hundreds of facilities would turn off previously required control equipment or increase their emissions. EPA\u2019s Regulatory Impact Analysis concluded that few facilities (estimated at 3.1 percent) would actually increase emissions under the rule and that at most the increases, if actually undertaken, would increase emissions from 919 tons to 1,258 tons per year. All of which depends on whether the states would allow the permit changes.<\/p>\n<p>There is sure to be a court challenge as there was for the policy and the proposed rule. Check TRC\u2019s regulatory updates for more developments as they occur.<\/p>\n<p><a class=\"btn btn-primary\" href=\"https:\/\/www.trccompanies.com\/contact-us\/\">Contact Us<\/a><\/p>\n                    <\/div>\n    <\/div>\n<\/section>\n<!-- End Block: acf\/innerpage-half-text-half-image --><\/div>\n<\/div><\/div><\/div>\n<!-- End Block: core\/column --><\/div>\n<\/div><\/div><\/div>\n<!-- End Block: core\/columns -->","protected":false},"excerpt":{"rendered":"<p>On October 1, 2020, the EPA finalized a ruling that no longer enforces the \u201conce in, always in\u201d air emissions policy.<\/p>\n","protected":false},"featured_media":6832,"template":"","tags":[133,602,135,203],"news-and-insights-category":[360],"services-category":[1001],"custom_category":[],"class_list":["post-1714","news-and-insights","type-news-and-insights","status-publish","has-post-thumbnail","hentry","tag-air-measurement","tag-air-quality","tag-air-quality-consulting","tag-epa","news-and-insights-category-regulatory-updates","services-category-environmental-assessment-permitting-compliance"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.9 -
