Integrated Compliance Information System (ICIS) National Pollutant Discharge Elimination System (NPDES) Discharge Monitoring Report (DMR) data sets for Clean Water Act permitted dischargers.

The document displays all the facilities in Harris County, Texas that have submitted a DMR. There are multiple lines for each facility due to outfalls and parameters. The spreadsheet is searchable by permittee name and EPA ID.

Each year the U.S. Environmental Protection Agency (EPA) reports permit, location, and discharge information for facilities across the United States and its territories through the Discharge Monitoring Report (DMR). Because these data are cataloged through a variety of systems, including self-reporting, there are discrepancies that may lead to incorrect spatial interpretation of content in the database. The processing of this quality assessed and modified dataset included steps to evaluate the accuracy and potential limitations of DMR data between 2007 and 2019. Attributes within this tabular dataset include facility and outfall locations as well as confidence ratings for those locations, and hydrologic unit code (HUC) 12 information on outfalls above a certain threshold of confidence. Discretion should be used when utilizing this dataset and users should ensure an understanding of the metadata or content in the DMR_ReadMe.docx file.

This EnviroAtlas dataset includes a number of Discharge Monitoring Report (DMR) metrics summarized by watershed for a given year (https://echo.epa.gov/help/loading-tool/watershed-statistics-help). These metrics include the number of facilities and wastewater discharges located within watersheds according to the Integrated Compliance Information System National Pollutant Discharge Elimination System (ICIS-NPDES), to track the permit compliance and enforcement status of facilities regulated by the NPDES under the Clean Water Act (https://echo.epa.gov/tools/data-downloads/icis-npdes-download-summary). This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
