CIMC (www.epa.gov/cimc) brings together the data from many of these cleanup programs and lets people map, list and access cleanup progress profiles for sites across the US so that people can know what is going on in their communities. The CIMC web service provides access to the mapping component of the CIMC web application. The Cleanups in My Community (CIMC) web service contains the following map layers: Incidents of National Significance (from the epa.gov website) – with links to the relevant web pages, Superfund NPL sites (propose, final and deleted)(from SEMS) – with links to the cleanup profiles, RCRA Corrective Action Sites (by various cleanup categories)(2020 baseline facilities only, not all RCRA sites because RCRA sites that are not corrective action are not cleanups)(from RCRAInfo) – with links to the cleanup profiles, Brownfields Properties (by grant type)(from ACRES) – with links to the cleanup profiles, Brownfields Grant jurisdictions (polygons)(from ACRES) – with links to the grant information, Federal facilities that are also Superfund or RCRA CA sites and BRAC (from the epa.gov page for federal facilities), Recovery Act locations (for Superfund and Brownfields only) (from SEMS and ACRES), Emergency removals (from EPAOSC.net). The CIMC web service was initially published in 2013, but the data are updated twice a month.

Section 7 of the ESA directs all Federal agencies to conserve endangered and threatened species and to use their authorities to ensure actions do not jeopardized the further existence of threatened and endangered species or adversely modify designated critical habitats. As part of the Section 7 coordination, federal agencies work with USFWS and NMFS to identify species found within the jurisdiction of the United that could be affected by actions carried out by the agency. Of note, the US EPA’s Office of Pesticide Programs (OPP) is responsible for ensuring that Agency actions under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) are in compliance with ESA.

Critical habitat may also include areas that are not currently occupied by the species but that may be needed for their recovery.

For some species, best available information is based on site specific surveys. For others, it will be historical location information based on political boundaries. These areas are, therefore, less geographically explicit than critical habitat. Consideration of both the species range and critical habitat ensures the conservation of the ecosystems upon which endangered and threatened species depend. To support EPA’s implementation of ESA, critical habitat and range data for species listed under ESA Section 7 were obtained by the US EPA from the USFWS Environmental Conservation Online System (ECOS) database in November 2020. These data were supplemented with areas provided by NOAA’s National Marine Fisheries Service (NMFS) where NOAA has species authority.

The dataset depicts the authoritative locations of the most commonly known Department of Defense (DoD) sites, installations, ranges, and training areas world-wide. These sites encompass land which is federally owned or otherwise managed. This dataset was created from source data provided by the four Military Service Component headquarters and was compiled by the Defense Installation Spatial Data Infrastructure (DISDI) Program within the Office of the Assistant Secretary of Defense for Energy, Installations, and Environment. Only sites reported in the BSR or released in a map supplementing the Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA) Real Estate Regulation (31 CFR Part 802) were considered for inclusion. This list does not necessarily represent a comprehensive collection of all Department of Defense facilities. For inventory purposes, installations are comprised of sites, where a site is defined as a specific geographic location of federally owned or managed land and is assigned to military installation. DoD installations are commonly referred to as a base, camp, post, station, yard, center, homeport facility for any ship, or other activity under the jurisdiction, custody, control of the DoD.\n\nWhile every attempt has been made to provide the best available data quality, this data set is intended for use at mapping scales between 1:50,000 and 1:3,000,000. For this reason, boundaries in this data set may not perfectly align with DoD site boundaries depicted in other federal data sources. Maps produced at a scale of 1:50,000 or smaller which otherwise comply with National Map Accuracy Standards, will remain compliant when this data is incorporated. Boundary data is most suitable for larger scale maps; point locations are better suited for mapping scales between 1:250,000 and 1:3,000,000.\n\nIf a site is part of a Joint Base (effective/designated on 1 October, 2010) as established under the 2005 Base Realignment and Closure process, it is attributed with the name of the Joint Base. All sites comprising a Joint Base are also attributed to the responsible DoD Component, which is not necessarily the pre-2005 Component responsible for the site.
