  5. Title: EPA 2014 Toxics Release Inventory - Oregon

    Contributors:

    Summary: The Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. Certain industrial facilities in the U.S. must report annually how much of each chemical is recycled, combusted for energy recovery, treated for destruction, and disposed of or otherwise released on- and off-site. This information is collectively referred to as production-related waste managed. This shapefile represent releases of TRI-covered chemicals to the environment in Oregon. A "release" of a chemical means that it is emitted to the air or water, placed in some type of land disposal, or transferred off-site for disposal or release.

  6. Title: 1:250,000 Scale Land Use and Land Cover, New York, 1990

    Contributors:

    Summary: This is derived from land use/land cover digital data collected by USGS and coverted to ARC/INFO by the EPA. This data is useful for environmental assessment of land use patterns with respect to water quality analysis, growth management, and other types of environmental impact assessment. Use may be limited due to currency. Land use and land cover data (LU/LC) collected by USGS NMD is useful for environmental assessment of land use patterns with respect to water quality analysis, growth management, and other types of environmental impact assessment. Data are meant to be used by quadrangle, or among adjacent quadrangles where temporarily contiguous. Can be used in any geographic application where intermediate scale land use data are appropriate and the dates are representative. The purpose of the original files was to convert GIRAS data into EPA's standard GIS software. For use with other demographic and spatial data.

  13. Title: Lead (Pb): Federal Area Designations: California, 2011

    Contributors:

    Summary: This polygon shapefile contains area designations of lead attainment (Pb) in California (Region 9). There are three categories of designations: : nonattainment, unclassifiable and attainment areas. These designations are based on the Environmental Protection Agengy's National Ambient Air Quality Standards 40CFR81.305 (February 22, 2011). Areas designated "Nonattainment" are geographic areas which have not met National Ambient Air Quality Standards for Lead (Pb) air pollution. These standards are part of the Clean Air Act. See Code of Federal Regulations, Section 40 Part 81, for detailed information about Ambient Air Quality Standards. Projection: Teale Albers, NAD83. This data set is intended to help provide the public with information to determine whether or not air quality within a given area is healthy. Once designations take effect, they also become an important component of state, tribal and local governments' efforts to control lead pollution. U.S. Environmental Protection Agency. (2011). Lead (Pb): Federal Area Designations: California, 2011. California Air Resource Board. Available at: http://purl.stanford.edu/xj215jd6930 Based on 40CFR81.305 (February 22, 2011).

  14. Title: Carbon Monoxide: California State Area Designations, 2008-2011

    Contributors:

    Summary: This polygon shapefile contains area designations of carbon monoxide (CO) levels in California as required under Health and Safety Code section 39608. The designations are consistent with the criteria established in the California Code of Regulations, title 17, sections 70300 through 70306, and Appendices 1 through 3, thereof. There are four possible designation categories: attainment, nonattainment, nonattainment-transitional, and unclassified. Nonattainment areas are geographic areas which have not met National Ambient Air Quality Standards for Carbon Monoxide air pollution. In addition, CO nonattainment areas have been assigned a classification, commensurate with the severity of their air quality problem, under Health and Safety Code section 40921.5. The State area designations are reviewed annually and approved by the State Air Resources Board. Projection: Teale Albers, NAD83 This shapefile can be used to identify state carbon monoxide pollution area designations from the prior three-year period (2008-2011) in accordance with the California State Ambient Air Quality Standard. U.S. Environmental Protection Agency. (2011). Carbon Monoxide: California State Area Designations, 2008-2011. California Air Resources Board. Available at: http://purl.stanford.edu/st637td0472. The State area designations are reviewed annually and approved by the State Air Resources Board. In 2011, staff did not propose any changes to the State carbon monoxide designations.

  15. Title: Particulate Matter (PM-2.5) Non-Attainment Areas: California, 2011

    Contributors:

    Summary: This polygon shapefile identifies areas in the U.S. where air pollution levels have not met the 2006 National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM-2.5) and have been designated "nonattainment". This category of particle pollution measurement monitors fine particles, such as those found in smoke and haze, that are 2.5 micrometers in diameter or smaller. These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air. The EPA Office of Air Quality Planning and Standards (OAQPS) has set National Ambient Air Quality Standards for six principal pollutants, which are called "criteria" pollutants. Under provisions of the Clean Air Act, which is intended to improve the quality of the air we breathe, EPA sets limits on how much of a pollutant can be in the air anywhere in the United States. This ensures that all Americans have the same basic health and environmental protections. The law allows individual states to have stronger pollution controls, but states are not allowed to have weaker pollution controls than those set for the whole country. EPA calls these pollutants "criteria air pollutants" because the agency has regulated them by first developing health-based criteria (science-based guidelines) as the basis for setting permissible levels. One set of limits (primary standard) protects health; another set of limits (secondary standard) is intended to prevent environmental and property damage. A geographic area that meets or does better than the primary standard is called an attainment area; areas that don't meet the primary standard are called nonattainment areas. This data set is intended to help provide the public with information to determine whether or not air quality within a given area is healthy. Once designations take effect, they also become an important component of state, tribal and local governments' efforts to control fine particulates. Environmental Protection Agency. (2011). Particulate Matter (PM-2.5) Non-Attainment Areas: California, 2011. California Air Resources Board. Available at: http://purl.stanford.edu/xj296sf2900 Based on 40 CFR 81.305 (February 22, 2011) Data are considered current to the date of the original source material.
