USER NOTES:

The United States Toxics Release Inventory (TRI) is mandated by Section 313 of the Emergency Planning and Community RighttoKnow Act (EPCRA) of 1986. The law is based on the premise that citizens have a right to know about potentially harmful chemicals in their communities. It has two main purposes: to provide planning for response to chemical accidents; and to provide the public and the government with information about possible chemical hazards.

This database contains data on annual estimated releases of over 300 toxic chemicals to air, water, and land by the manufacturing industry.

Industrial facilities provide the information, which includes: the location of the facility where chemicals are manufactured, processed, or otherwise used; amounts of chemicals stored on site; estimated quantities of chemicals released; onsite source reduction and recycling practices; and estimated amounts of chemicals transferred to treatment, recycling, or waste facilities.

The TRI data for chemical releases to land are limited to releases within the boundary of a facility. Releases to land include: landfills; land treatment/application farming; and surface impoundments, such as topographic depressions, manmade excavations, or diked areas. Air releases are identified as either point source releases or as nonpoint (i.e. fugitive) releases, such as those occurring from vents, ducts, pipes, or any confined air stream. Surface water releases included discharges to rivers, lakes, streams, and other bodies of water. In addition, the database covers releases to underground injection wells (where chemicals are injected into the groundwater) and offsite transfers of chemicals to either publicly owned treatment works (POTWs) or any other disposal, treatment, storage, or recycling facility.

Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data.

1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries.

1:100000 scale datasets are recommended for projects that are at the multicounty or regional level.

1:250000 scale datasets are recommended for projects that are at the regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

DATA LINEAGE SUMMARY:

The BASINS TRI data layer for the conterminous U.S. was created through further processing of ESDLS spatial coverage http://www.epa.gov/enviro/html/esdls/esdls_over.html of EPA regulated facilities and from selected TRI data downloaded from the Envirofacts Oracle database http://www.epa.gov/enviro/html. The ESDLS coverage is broken into four separate Arc/Info coverages representing the NE, SE, NW and SW quadrants of the conterminous U.S. was downloaded from ftp://ftp.epa.gov as compressed Arc/Info export (e00) files. The coverages were reprojected from Albers Conic Equal Area projection with datum NAD83 to geographic decimal degrees. They were then converted to Arcview shape files using the Arc/Info ARCSHAPE command. Using Arcview, the shape files were merged to produce a single shape file that contains the point locations of EPA regulated facilities for the entire conterminous U.S. The shape file that contains the point locations of TRI facilities was generated by selecting only the facilities that fall under the TRI program system. Facilities that are shown to be located (e.g. based on latlong coordinates) outside the land boundary of the conterminous U.S. were excluded. Selected attribute tables were downloaded from the Envirofacts database to supplement the attribute data that was available in the ESDLS coverage. The TRI_FACILITY table in the Envirofacts database which contains general information of the facilities in TRI is joined permanently with the primary attribute table of the ESDLS coverage to produce the new primary attribute table of the BASINS TRI data layer. The related tables which contain the annual toxic releases were obtained from the tables TRI_AIR_EMISSION, TRI_LAND_RELEASE, TRI_UNDERGROUND_INJECTION, TRI_WATER_DISCHARGE, and TRI_TRANS_POTW8.

Limitations_of_Data: Not all TRI sites reported in the conterminous U.S. are included. For example, sites with no assigned locational coordinates cannot be included.

The QA process consists of first ensuring no error in reporting or data entry of the facility coordinates. If possible any errors found here are corrected before continuing with the QA process. The next step involves checking coordinates against a 1 km buffer of the ZIP code region for the reporting facility. The coordinates of the facility should fall within the buffered zip code boundary. General QA is also performed on the data. This consists of spot checking fields and the data they contain. A visual check is also performed for placement of each facility.

TRI data (without additional geographic coordinates) is available online for interactive search and retrieval from the following sources:

The BASINS Water Quality Monitoring and Data Summaries for the conterminous U.S. are created by retrieving the source data from the STORET database using the STORET MEAN program. Monitoring stations characterized as ambient stream, lake, reservoir, canal, estuary or ocean were selected. Summary statistics were computed by the program by station for 5year intervals from 19701994 and for the period from 19951997. Statistics include number of observations, standard deviation, mean, 15th, 25th, 50th, 75th and 85th percentiles. A BASINS water quality station ID was assigned to each station in order to facilitate links and joins within BASINS between station data and the monitoring data summary.

For distribution with BASINS v2.0, ARCVIEW shapefiles which included the spatial extent of each of the ten U.S. EPA Regions, plus the 8digit hydrologic units that crossed region boundaries were prepared to indicate the geographic locations of the monitoring stations within the region.

For distribution with BASINS v.2.0, the spatial attributes of the database were prepared in Arcview shape file format while selected relational attributes were prepared in Arcview DBF file format.
