Acronym for lean ir ct Can Velocity Velocity of the baghouse process air as it flows upward though the rows of bags. Formula: Area of the Baghouse in Square Feet minus the area of the diameter of the filter bags divided by the ACFM of the process air. Excessive Can Velocity can cause premature bag wear due to abrasion and can cause more dust to be carried upward to the bags overloading the bags and the cleaning system. Conversely a Low Can Velocity can cause segregation of the incoming dust carrying only the finest of particles which can prevent the formation of a good Dust Cake
Clean Air Act The Clean Air Act establishes national requirements for airborne emissions, including both stack emissions and "fugitive" emissions from leaks and other sources. EPA, state, and regional air quality agencies are all likely to be involved in CAA implementation. See Also: BACT, CAP, CEMS, HAP, MACT, NAAQS, NESHAP, NSPS, NSR, PSD, RMP, SIP...................
Clean Air Act: Federal legislation that requires each state with areas that have not met federal air quality standards to prepare a State Implementation Plan, or SIP. The sweeping 1990 amendments to the CAA established new air quality requirements for the development of metropolitan transportation plans and programs. The California Clean Air Act or (CCAA) sets even tougher state goals.
Clean Air Act. The original Clean Air Act was signed in 1963. The law set emissions standards for stationary sources (e.g., factories, power plants). The CAA was amended several times, most recently in 1990 (P.L. 101-549). The Amendments of 1970 introduced motor vehicle emission standards (e.g., automobiles, trucks). Criteria pollutants included lead, ozone, CO, SO2, NOx, and PM as well as air toxics.
Clean Air Act. Identifies actions to be taken by states and MPOs to reduce emissions from on-road mobile sources.
Clean Air Act. The primary federal law governing the regulation of emissions into the atmosphere. Originally passed in 1963, it has been amended several times with major changes occurring in 1970 and 1990. In 1970, primary responsibility for administering the CAA was given to the newly created Environmental Protection Agency. This act required promulgation and ongoing enforcement of National Ambient Air Quality Standards and National Emission Standards for Hazardous Air pollutants, which limit the maximum local concentrations of various air pollutants. In addition, the act limits the amount of various pollutants that vehicles may emit. The 1990 amendments set stricter provisions for motor vehicle emissions, attainment of the national ambient air quality standards, and specific restrictions on use or emissions of chlorofluorocarbons, NOx, and sulfur dioxide (SO2). The SO2 restrictions involve a system of tradable emissions allowances.
Clean Air Act; federal law enacted to regulate/reduce air pollution. Administered by EPA.
Clean Air Act was enacted to regulate/reduce air pollution. CAA is administered by the U.S. Environmental Protection Agency (EPA).
Clean Air Act. The original Clean Air Act was passed in 1963, but our national air pollution control program is actually based on the 1970 version of the law. The 1990 Clean Air Act Amendments are the most far-reaching revisions of the 1970 law. In this glossary, we refer to the 1990 amendments as the 1990 Clean Air Act.
Clean Air Act of 1963 (U.S.)
Clean Air Act. long standing federal legislation that is the legal basis for the national clean air programs, last amended in 1990
Clean Air Act. In the U.S., the fundamental legislation to control air pollution. The original Clean Air Act was signed in 1963. The law set emissions standards for stationary sources, such as factories and power plants. Criteria pollutants included lead, ozone, CO, SO2, NOx and PM, as well as air toxics. The CAA was amended several times, most recently in 1990. The Amendments of 1970 introduced motor vehicle emission standards for automobiles and trucks.
Clean Air Act; Compliance Assurance Agreement
Clean Air Act: Federal legislation that sets air quality standards. Sometimes cited as CAAA, which usually refers to the Clean Air Act Amendments of 1990, the first major revision of the original law in 20 years.
