On Friday, EPA announced that it was reconsidering its 2020 decision to leave the National Ambient Air Quality Standards for ozone unchanged. However, EPA stated that it: will reconsider the decision to retain the ozone NAAQS in a manner that adheres to rigorous standards of scientific integrity.
Multiple lines of analysis make clear that regardless of how cheap wind and solar power get, without directly addressing pollution from coal and gas plants, the country’s clean energy transition will not happen fast enough. Section 111 of the CleanAirAct constrains how EPA sets standards—but gives states wide latitude in implementation.
The downwind air quality benefits are minimal. The proposed rule would provide de minimus air quality benefits in downwind areas with extremely high costs – estimated by EPA at $22 billion discounted 2016 dollars for the 2023-2042 period. enjoyed ozone reductions of 3 to 5 ppb or more. ppb by 2025. EPA estimated that: .
In 2015, a total volume of 598.3 billion in 2015. [4]. In 2015, a total volume of 598.3 billion in 2015. [4]. The South Coast Air Basin includes portions of Los Angeles, Riverside, and San Bernardino counties and all of Orange County, covering 6,745 square miles. million tons of freight valued at US$1.7
On January 20, 2021, the Ohio EPA’s Division of Air Pollution Control (DAPC) hosted a “Program Advisory Group” (PAG) meeting via Microsoft Teams to inform interested stakeholders of recent and upcoming DAPC activities. This post focuses on Ohio EPA’s anticipated regulatory changes to address non-attainment of the 2015Ozone NAAQS.
Ohio EPA has proposed rules that will require additional Volatile Organic Compound (VOC) and Nitrogen Oxide (NOx) emission controls for certain manufacturing and industrial operations located in the Cincinnati and Cleveland 2015ozone nonattainment areas. Like VOCs, NOx is a precursor compound which can form ozone.
Circuit also rejected EPA’s argument that the court did not have authority to review stays issued under Section 307(d)(7)(D) of the CleanAirAct. Fourth Circuit Said West Virginia District Court Lacked Jurisdiction to Consider Coal Companies’ CleanAirAct Jobs Study Lawsuit. DECISIONS AND SETTLEMENTS.
Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone. They are water vapor, carbon dioxide, methane, nitrous oxide, ozone, CFCs, and hydrofluorocarbons.
The federal CleanAirAct (CAA) was enacted in 1970 and amended in 1977 and 1990. EPA regulations under the CleanAirAct for controlling mercury, sulfur dioxide, ozone and other pollutants have contributed to the employment decline. Source: US DOE/EIA. Source: US DOE/EIA.
is a shift for this historically CleanAirAct-friendly Court. EPA) is one for the CleanAirAct (CAA) record books. Since the CleanAirAct was enacted in 1970, EPA has been directed to regulate the emission of toxic chemicals by coal and oil fired power plants but had neglected to do so.
President John F Kennedy introduced the CleanAirAct in the US as one of many introduced in developed nations with heavy industry (15). At the last census in 2015, it was estimated that species numbers were anything between 19,500 and 21,000. As recently as the 1960s, there were just 840 individuals.
But the CleanAirAct has nonetheless had a major impact. Here’s what EPA has to say on the subject — and remember, this is from the Trump EPA, which is no fan of regulation: Experience with the CleanAirAct since 1970 has shown that protecting public health and building the economy can go hand in hand.
Notably, in granting the Advanced Clean Car waiver , EPA relied heavily on the fact that the program cuts traditional air pollutants, including those that cause ozone pollution, from vehicles. Californias power under the federal CleanAirAct to cut pollutants from cars and trucks is unquestionable and longstanding.
In 2015, when he took office as AG after stints in the Texas Legislature, he sued the Environmental Protection Agency for strengthening a standard for ground-level ozone, better known as smog. EPA decision , upheld the EPA’s authority to regulate such emissions under the CleanAirAct but significantly constrained its ability to do so.
Methane also contributes to the formation of ground-level ozone which is itself a heat-trapping greenhouse gas and, when inhaled by humans, can trigger a variety of health problems from throat irritation and coughing to bronchitis, asthma, and reduced lung function.
This body will review the EPA’s scientific review of current ozone pollution standards. In 2019, the Trump administration opted to keep ozone pollution standards the same. EPA – CleanAirAct Advisory Committee Meeting (Feb. The Biden administration announced this is it revisiting that decision in 2021.
Earlier this month, the Environmental Protection Agency’s (EPA) CleanAir Scientific Advisory Committee (CASAC) released a draft set of recommendations calling on the EPA to tighten its current standard for ground-level ozone pollution to protect public health. But will the EPA follow CASAC’s recommendations?
The backstory: The question of which streams and wetlands are federally regulated under the Clean Water Act has been in limbo for the past decade and a half, since the Supreme Court issued a muddled decision in the 2006 case Rapanos v. EPA – Proposed Consent Decree, CleanAirAct Citizen Suit. United States.
EPA of a 2015 rule barring replacement of ozone-depleting substances with hydrofluorocarbons (HFCs), which are powerful greenhouse gases. Circuit vacated the 2015 rule to the extent that it prohibited continued use of HFCs by companies that previously switched to HFCs from an ozone-depleting substance.
The Environmental Protection Agencys final rule (September 10, 2024) on the reclassification of major sources as area sources under section 112 of the CleanAirAct. The Environmental Protection Agencys final rule (October 10, 2024) regulating ozone-depleting substances.
