ICIS-NPDES Search User Guide

This search allows you to retrieve selected data from the Integrated Compliance Information System (ICIS) databases in Envirofacts regarding facilities registered with the federal enforcement and compliance (FE&C) and holding National Pollutant Discharge Elimination System (NPDES) permits. NPDES tracks permit issuance, permit limits and monitoring data, and other data pertaining to facilities regulated under NPDES.

This is a brief user guide to the ICIS-NPDES Search. You can narrow your search by selecting various options including facility name, geographic location, facility industrial classification, and chemicals. Only those facilities matching all specified criteria will be retrieved. Select more than one search option at a time to speed up the search and make the retrieval more focused. The searches are highly dependent on the geographic location, and a state or ZIP Code is required for all searches except for Facility Name or ID.

Facility Identification Search Option

Search by Facility Name or NPDES ID.

Facility Name

Enter the complete or partial facility name to retrieve all facilities with that name. Select the "Containing" option when entering a partial name for a better retrieval the first time you access the data. When an "Exact Match" option is specified for a facility name, only facilities that exactly match the name as entered will be retrieved.

NPDES ID

Enter the complete (nine-character) or partial NPDES ID to retrieve all facilities with that ID. Select the "Containing" option when entering a partial ID for a better retrieval the first time you access the data.

Geography Search Option

Select from the following geographical search options: ZIP Code, Address, City, County, and State. A state entry is required for all searches except for Facility Name or ID or ZIP Code.

ZIP Code

Enter a full five-digit ZIP Code. ZIP+4 formats are also supported.

Address

Enter a complete or partial street address.

City

Enter a complete or partial city name. State selection is required.

County

Enter a complete or partial county name. State selection is required.

State

Select a state name from the dropdown list. The list is alphabetical by state name followed by territories.

Note: We strongly recommend that you enter a small geographical area to begin the search since Envirofacts contains a large number of facilities.

Facility Industrial Classification Search Option

SIC Code Search

The first two digits in the code define a major business sector, and the last two digits denote a facility's specialty within the major sector. For the “Exact Match” option enter a 4-digit SIC code. For “Beginning with” or “Containing” enter up to 4 digits.

Parameter (Chemical) Name Search Option

Parameter Code

Enter the Parameter Code or look up the appropriate Parameter Code using the ICIS REST API at https://data.epa.gov/dmapservice/icis.ref_parameter/.

Parameter Code Name

Enter a complete or partial chemical (parameter) name. There can be various common names for the same chemical, so if the name you enter is not listed under that name for the facility, the ICIS-NPDES Search will not retrieve the facility.

Permit Expired Date Search Option and Permit Issued Date Search Option

Enter a date range by clicking on two dates to find permits issued or expiring within specific periods. If you enter a single date, the system will not return results.

Search Values Option

Select Use Multisystem facility information to perform facility search to identify facilities using facility information from all program systems. Select Use ICIS-NPDES facility information only to perform facility search to identify facilities using only ICIS-NPDES facility information.

Major Dischargers Only

Check this option to retrieve only facilities that have been identified as major dischargers.

Output

ICIS-NPDES facilities range from public sewage treatment works to large petrochemical plants. Any business location (public, private, or federal) that discharges into the nation's lakes, rivers, or streams should be a ICIS-NPDES facility.

Basic Facility Information

ICIS-NPDES facilities obtain a permit from EPA or a State authority which "permits" the facility to discharge specified pollutants up to a defined limit. These permits generally expire after 5 years and have to be renewed by EPA or the State authority.

The ICIS-NPDES search results identify the facility's geographic location and consist of the following variables:

NPDES ID: Click the hyperlinked NPDES ID to see an ICIS Detailed Report for the facility.
Facility Information: Click on "View Facility Information" to view the Facility Registry System report for that facility.
Facility Name
Address: The Facility Address is a combination of the following individual attributes in the ICIS-NPDES system:
County Name
Latitude/Longitude
Permit Issued Date
Permit Expired Date
SIC Code/SIC Description
Mapping Info: Provides a link to the Envirofacts Multisystem report which includes a map.

ICIS Detailed Report

ICIS-NPDES facilities obtain a permit from EPA or a State authority which "permits" the facility to discharge specified pollutants up to a defined limit. Certain parameters (chemicals, water temperature, oxygen content, etc.) of the facility discharge are monitored by EPA or the State to ensure that the facility does not exceed its permit. The ICIS Detailed Report identifies the geographic location of the facility, the discharge points (pipes) of the facility, and the parameters that are monitored for each discharge point.
