The EPA elected to not modify the Pb NAAQS further, but decided to instead focus on the 1991 U.S. EPA Strategy for Reducing Lead Exposure. The EPA concentrated on regulatory and remedial clean-up efforts to minimize Pb exposure from numerous non-air sources that caused more severe public health risks, and undertook actions to reduce air emissions.
Ohio v. EPA, No. 23A349, 603 U.S. ___ (2024) The Clean Air Act (CAA) is the United States' primary federal air quality law, intended to reduce and control air pollution nationwide. Initially enacted in 1963 and amended many times since, it is one of the United States' first and most influential modern environmental laws.
The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
The EPA says there are 9.2 million lead pipes in the United States. Exposure to lead in children, even at low levels, can lead to numerous health defects, including impaired hearing, learning ...
Other pollutants, such as lead, were added later based on EPA review of current conditions. Along with the other activities set by the EPA, the states were to create State Implementation Plans (SIP)s to bring their air quality within the NAAQS by 1975. The Amendment also required the EPA to define emission standards for new vehicles to help ...
The United States Environmental Protection Agency (EPA) began regulating greenhouse gases (GHGs) under the Clean Air Act ("CAA" or "Act") from mobile and stationary sources of air pollution for the first time on January 2, 2011. Standards for mobile sources have been established pursuant to Section 202 of the CAA, and GHGs from stationary ...
The EPA's Lead National Ambient Air Quality Standards (NAAQS) Non-attainment Designations list designates a total of 21 areas and parts of 22 counties across 15 states and Puerto Rico that are in violation of federal air quality health standards for lead emissions. [49]
Non-attainment area. In United States environmental law, a non-attainment area is an area that exceeds pollution limits for one or more criteria pollutants: ozone (O 3), atmospheric particulate matter (PM 2.5 /PM 10), lead (Pb), carbon monoxide (CO), sulfur oxides (SO x), and nitrogen oxides (NO x).
