Data Quality Caveat: EPA makes no claims regarding the accuracy or precision of data concerning Indian country locations or boundaries on the ECHO website. EPA has simply attempted to collect certain readily available information relating to Indian country locations. Questions concerning data should be referred to the originating program or Agency which can be identified in the Envirofacts tribal query metadata files Lower48 Tribal AreasAlaska ReservationAlaska Native Villages , or Alaska Native Allotments . The Indian country locations shown here are suitable only for general spatial reference and do not necessarily reflect EPA's position on any Indian country locations or boundaries or the land status of any specific location. The inclusion of Indian country information on the ECHO website does not represent any final EPA action addressing Indian country locations or boundaries. This information cannot be relied upon to create any rights, substantive or procedural, enforceable by any party in litigation with the United States or third parties. EPA reserves the right to change information on ECHO at any time without public notice.

EPA uses the U.S. Census Bureau 2010 tribal boundary layer data when developing environmental data query responses for tribes in the lower 48 United States and Bureau of Land Management Alaska State Office when developing environmental data query responses for tribes in Alaska. The tribal boundary locations identified are suitable only for general spatial reference and do not necessarily reflect EPA's position on any Indian country locations or boundaries, or the land status of any specific location. EPA seeks to use the best available national federal data and may refine the tribal boundary layer in the future as more accurate national federal data becomes available.

Facility/System Characteristics

Facility Name
Search for facilities or permits by name or partial name. Be sure to try all possible variations of a facility's name. For example, if an abbreviation does not work, try using whole words (i.e., International Metals Company instead of INMETCO). The search is not case sensitive.
Words separated by a space are treated as one search term. Separate multiple search terms with a semi-colon (“;”). Alternatively, click the Add More button to add a value to the Selected Search Criteria panel and clear the input field for a new value.
The search returns facilities that match any of the search terms. Note that a match may be found within any of the current facility names associated with the Facility Registry Service (FRS) ID; however, only the primary facility name is displayed in the search results table. The primary facility name may differ depending on the selected search type (e.g., the All Data search results table displays the facility name in FRS). For more information, see Facility Search Results Help .
Use the dropdown list adjust the facility name search logic. You do not need to use wildcard characters (* or %) in the Facility Name field to specify search logic. Note: You can only associate one type of search logic with selected search terms.
Find Facility Name(s) That:
  • Contains Each Term (DEFAULT) - Returns facilities where all words in the facility name search terms are present in the facility name. The order of the words in a search term does not affect the search results.
    For example, searching for “town bridge” returns results that contain both “town” and “bridge” within the facility name, e.g., “Bridgeport Township” or “Middletown Bridge”
  • Matches Exactly - Returns facilities where the facility name search terms exactly match the facility name.
    For example, searching for “The First Company” only returns results with a facility name exactly matching all terms and in this order.
  • Matches Exact Phrase - Returns facilities where all search terms are found anywhere within the facility name. The order of the words in a search term affects the search results.
    For example, searching for “town bridge” returns different results than searching for “bridge town”
  • Begins With - Returns facilities where the facility name search terms are found at the beginning of the facility name.
    For example, searching for “bridge” returns results that begin with “bridge”, such as “Bridgeport” and “Bridgestone,” but excludes results like “Middlebridge”.
Facility ID Number
Search for facilities or permits by their NPDES identification numbers. Allows data entry of up to 2,000 IDs pasted from spreadsheet column, or comma- or return-separated.
Note that active/operating facility or permit status is selected by default on the search form. If facilities ID are entered with active facility status also selected, you will not include inactive facilities in your search. Because some of the facility IDs may represent inactive facilities, records for all of the facility IDs may not be returned on the Search Results page.
SIC Code (Industrial Stormwater Only)
The Standard Industrial Classification Code describes the primary activity of the facility. The first two digits in the code define a major business sector; the last two digits denote a facility's specialty within the major sector. ECHO allows you to search SIC Codes in multiple ways:
  • Choose a 2-digit SIC Code from the drop-down menu.
  • Type the 3- or 4-digit SIC Code into the text box. Click the Add More button to add a value to the Selected Search Criteria panel and clear the input field for a new value.
  • SIC Code Lookup - Search for SIC codes by keyword.
NAICS Code (Industrial Stormwater Only)
The North American Industry Classification System (NAICS) replaced the U.S. Standard Industrial Classification (SIC) system. NAICS industries are identified by a 6-digit code. The first two digits represent the Industry sector, in which there exist 20 broad sectors. The third digit represents industry subsector, the fourth digit represents industry group, the fifth digit represents industry, and the sixth digit is U.S., Canadian, or Mexican National specific. ECHO allows you to search NAICS codes by general industry sector (the two-digit NAICS code) or by industry specialty (the three, four, five, or six-digit NAICS Code).
  • Type the 2-, 3-, 4-, 5-, or 6-digit NAICS code into the text box. Click the Add More button to add a value to the Selected Search Criteria panel and clear the input field for a new value.
  • NAICS Code Lookup  – Search for NAICS codes by keyword.
Federal Facility (Industrial Stormwater Only)
When "YES" is selected, your search results will be limited to federal facilities identified in multiple EPA national databases (ICIS-Air, ICIS-NPDES, RCRAInfo, ICIS FE&C, and TRI). These data are comprised of a mixture of state- and EPA-entered data and facility-reported and have not received the level of data quality review that the FRS data has. When "NO" is selected, your search results will exclude any federal facilities. "ANY" is the default and will not restrict search results.
Permit Status
Search for a facility or permit by permit status. The Permit Status values reflect the stages in the permit life cycle. Hold down the CTRL key to select multiple statuses.
  • Effective - A permit that is in its lifetime (Effective Date <= current date < expiration date).
  • Expired - A permit that 90 days after the expiration date has been reached on a permit that has no new Application Received Date or Complete Application Received date entered.
  • Administratively Continued - A permit that is at the permit's expiration date. All monitoring data are still collected and used against the permit’s terms.
  • Pending - A permit with incomplete data or a permit with an Effective Date that has not yet been reached.
  • Retired - A permit that all monitoring data is stopped against a retired permit; used in conjunction with Reissue. If a Permit is reissued before its expiration date, the Permit Status Code or the previous version of the Permit will be set to Retired.
  • Terminated - A permit that if the user enters the Termination Date, upon that date being reached, the system will automatically change the Permit Status Code to Terminated.
  • Not Needed - A facility is tracked in the EPA program database, ICIS-NPDES, but is not required to have a NPDES permit.

Effective, Expired, Administratively Continued, Pending, and Retired are selected by default for Industrial Stormwater searches. "Any" does not restrict search results.

Advanced/Government Search IconPermit Type (Biosolids Only)
Search for a facility or permit by permit classification. Permit classifications include:
  • NPDES Individual Permit - An individual NPDES permit is unique to each facility. The limitations and other conditions in an individual permit are based on the facility's operations, type and amount of discharge, and receiving stream, among other factors.
  • General Permit Covered Facility - A NPDES facility that is covered under a Master General Permit.
  • NPDES Master General Permit - A NPDES permit that covers multiple facilities that have similar discharges and are located in a specific geographic area. A general permit applies the same or similar conditions to all dischargers covered under the general permit. This is the record for the general permit that is issued by the permitting authority. It sets the conditions with which permittees will be required to comply. The Master General Permit contains no facility-specific data, and compliance and enforcement data are associated with a Master General Permit (rather any data would be associated with the General Permit Covered Facility).
  • Associated Permit Record - A system record associated to a NPDES permit.
  • Individual IU Permit (non-direct discharge) - Industrial user in a pretreatment program (NPDES indirect discharger). Although an industrial user is not issued an NPDES Permit, a permit record is maintained for tracking purposes.
  • Individual State Issued Permit (Non-NPDES) - An individual permit unique to each facility, but not in the NPDES program.
  • State Issued Master General Permit (Non-NPDES) - A state issued permit that covers multiple facilities that have similar discharges. The master general permit contains no facility-specific data.
  • Unpermitted Facility - A facility that does not have an active NPDES permit.
NPDES Individual Permit, General Permit Covered Facility, and Unpermitted Facility are selected by default for Industrial Stormwater searches. "Any" does not restrict search results.
Permit Components (Biosolids Only)
Search for an NPDES Permit with one of the following permit components:
  • Biosolids - Biosolids (formerly referred to as "sewage sludge") are the nutrient-rich organic materials resulting from the treatment of sewage sludge (the name for the solid, semisolid or liquid untreated residue generated during the treatment of domestic sewage in a treatment facility). When treated and processed, sewage sludge becomes biosolids which can be safely recycled and applied as fertilizer to sustainably improve and maintain productive soils and stimulate plant growth. Biosolids are regulated under 40 CFR Part 503. 40 CFR Part 503 establishes standards, which consist of general requirements, pollutant limits, management practices, and operational standards, for the final use or disposal of biosolids.
  • Concentrated Animal Feeding Operation (CAFO) - An NPDES permit regulating discharge from Concentrated Animal Feed Operations (CAFOs). CAFOs are animal feeding operations with more than 1,000 animals. CAFOs with a point source discharge are to receive permits.
  • Combined Sewer Overflow (CSO) - A combined sewer overflow (CSO) refers to a discharge of untreated wastewater from a combined sewer system at a point prior to the headworks of the publicly-owned treatment works. (59 FR 18688) CSOs generally occur in response to wet weather events. Most combined sewer systems are designed to discharge excess flow directly to surface water bodies, such as streams, rivers, estuaries, and coastal waters.
  • Publicly Owned Treatment Works (POTW) - The term Publicly Owned Treatment Works or POTW means a treatment works as defined by section 212 of the Act, which is owned by a State or municipality (as defined by section 502(4) of the Clean Water Act). This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal sewage or industrial wastes of a liquid nature. It also includes sewers, pipes and other conveyances only if they convey wastewater to a POTW Treatment Plant. The term also means the municipality as defined in section 502(4) of the Clean Water Act, which has jurisdiction over the Indirect Discharges to and the discharges from such a treatment works.
  • Pretreatment - An NPDES permit that prescribes for the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing such pollutants into a publicly owned treatment works [40 CFR 403.3(q)].
  • Storm Water - Construction - Permit requirements associated with construction activities, as defined at 40 CFR 122.26.
  • Storm Water - Industrial - Permit requirements associated with non-construction activities at industrial facilities, as defined at 40 CFR 122.26(b)(14)(i) through (xi).
  • Storm Water - Medium/Large Municipal Separate Storm Sewer System (MS4s) - Additional requirements for medium/large municipal separate storm sewer systems (MS4s), as defined at 40 CFR 122.26.
  • Storm Water - Small Municipal Separate Storm Sewer System (MS4s) - Additional requirements for small municipal separate storm sewer systems (MS4s), as defined as 40 CFR 122.30-122.37.
  • Blank (e.g., Standard-only) - A standard-issued individual NPDES permit without any additional permit components.

Information on Severity of Violations
Current Compliance Status (Industrial Stormwater Only)

In Significant Noncompliance (SNC)/Category I Violations - Violations by point source dischargers of sufficient magnitude or duration to be a regulatory priority. The national program database calculates the severity of violations according to the Clean Water Act regulations, which have specific criteria specifying the duration, severity, and type of violations that rise to the level of SNC. The calculation of Category I Violations is equivalent to the SNC calculations, but because the violations occur at smaller dischargers (non-major), EPA does not classify the violations as "SNC". Repeat SNC occurrences normally are addressed through formal enforcement actions, while Category I Violations are often addressed via informal processes. (SNC/Category I types in order of severity: S=Compliance Schedule Violations, E=Effluent Exceedance Monthly, X=Effluent Exceedance Non-monthly, T=Compliance Schedule Non-receipt, D=Discharge Monitoring Report Non-receipt)

RNC/Category II Violations - Violations that are not significant upon first discovery but become significant if repeated. The noncompliance reports do not have to be submitted immediately, but are to be included the next time the facility submits monitoring reports to the regulatory agency.

  • Any Compliance Status - Does not restrict search results.
  • No Violations - No violation recorded in the current quarter.
  • Effluent Violations: Significant Violations - The facility has exceeded the effluent restrictions established by a state or EPA on quantities, rates, and concentrations in wastewater discharges, and the exceedances meet the SNC/Category I criteria.
  • Effluent Violations: Violations - The facility has exceeded the effluent restrictions established by a state or EPA on quantities, rates, and concentrations in wastewater discharges, and the exceedances do not meet the SNC/Category I criteria. Note: This selection considers the most current data available, including effluent exceedances reported after the last Quarterly Noncompliance Report (QNCR) was issued; post QNCR data are considered draft and have not been fully quality assured.  A QNCR description is provided in the  Detailed Facility Report Data Dictionary
  • Violations of Compliance Schedule: Significant Violations - An enforcement action has been issued, and the facility is not meeting its compliance schedule or failed to submit required data.
  • Failure to Report: Significant Violations - Discharge Monitoring Report (DMR) not received.
  • Failure to Report: Violations - Discharge Monitoring Report (DMR) missing data.
Advanced/Government Search Icon Compliance Tracking (Biosolids Only)
Search for NPDES permits based on compliance tracking statuses in ICIS-NPDES. The Compliance Tracking selections can assist you in interpreting the compliance status, particularly for non-major permittees. There are two components of compliance tracking, including Discharge Monitoring Report (DMR) non-receipt tracking and facility-level compliance status tracking. Note that compliance tracking may not be entered for some permits, as it does not apply to "Not Needed" or "Pending" permit statuses or "Unpermitted" permit type. The compliance tracking statuses can only be turned off for non-major permittees.
  • "On" generally indicates that data are being entered and all system compliance tracking is on. In ICIS-NPDES, Permit Compliance Tracking Status and DMR Non-Receipt Status are both set to "Yes".
  • "Partial" generally indicates that some data are being entered, effluent exceedances and most facility-level status types are being identified, but DMR non-receipt is not being tracked, which suggests not all DMR data are being entered. In ICIS-NPDES, Permit Compliance Tracking Status is set to "Yes" and DMR Non-Receipt Status is set to "No".
  • "Off" indicates that data both compliance tracking flags are off (i.e., ICIS-NPDES will not determine a facility-level compliance status). In ICIS-NPDES, Permit Compliance Tracking Status is set to "No." Facilities with compliance tracking "off" may have violations on their hard copy DMRs that are not recorded in the ICIS-NPDES database.
Biosolids Violation Type (Biosolids Only)
Search for facilities with specific biosolids violations using the dropdown menu. Enter at least one character to filter dropdown options. Multiple selections are allowed; however, users may only select one value at a time from the dropdown list. Select between "Annual Report" or "Compliance Monitoring" to narrow the dropdown to the violation type. By default, "Any" is selected and displays all violation types. Note:  "B0024 - Management Practice Violations – Biosolids/Sewage Sludge Violation (Part 503 and State Regulations)" is the historic (inactive) biosolids violation code in ICIS, but still searchable in ECHO for the previous 3 years. And violations reported on the 2016 Biosolids Annual Report are not updated with the weekly data refresh and may not be representative of a facility's recently submitted or updated report. 
Biosolids Violation in Last Year (Biosolids Only)
Select "Yes" to search for facilities in violation for biosolids under the Clean Water Act in quarter 12 or 13. Select "No" to search for facilities that are not in violation for biosolids under the Clean Water Act, in quarter 12 or 13. Selecting a Violation Type will restrict Biosolids Violation in Last Year to the selected Violation Type. Note: Violations reported on the 2016 Biosolids Annual Report are not updated with the weekly data refresh and may not be representative of a facility's recently submitted or updated report. 
Quarters in Violation (3 years) (Industrial Stormwater Only)
Use the dropdown menu to search based on the number of quarters a facility, permit, or system was in violation over the past 3 years.
Quarters in Violation for Biosolids (3 years) (Biosolids Only)
Use the dropdown menu to search based on the number of quarters, out of the last twelve quarters, in which the permit or site is considered either with violations or in noncompliance (NC) status for biosolids. A quarter is any of the following 3-month calendar periods: January-March, April-June, July-September, or October-December. Note: Violations reported on the 2016 Biosolids Annual Report are not updated with the weekly data refresh and may not be representative of a facility's recently submitted or updated report. 
Informal Enforcement Actions
Search for a facility or permit based on an informal enforcement action or notice of violation issued to the facility. To specify your date range, select either "Within" or "None Within" and use the slider to select up to the past 5 years. When a value other than “No Restrictions” is selected, you can focus your search further by selecting an agency. 
Formal Enforcement Actions
Search for a facility or permit based on the time elapsed since the most recent formal civil or administrative enforcement action taken against the facility. To specify your date range, select either "Within" or "None Within" and use the slider to select up to the past 5 years. When a value other than "No Restrictions" is selected, you can focus your search by choosing one of the following criteria:
  • By Agency - The environmental agency that issued the enforcement action. "Any" does not further restrict search results.
  • By System - The EPA source database containing information about the enforcement action. "ICIS Only" will return facilities with enforcement action information found in the ICIS Federal Enforcement and Compliance database (ICIS-FE&C). "All Systems" does not further restrict search results.
Advanced/Government Search IconFormal Enforcement Type (Biosolids Only)
Search for a facility or permit based on the type of action the enforcement authority used.
Formal enforcement types include:
  • Administrative - Formal (AFR) - Non-judicial enforcement actions taken by EPA or a state under its own authority, without involving a judicial court process.
  • Judicial (JDC) -  Formal lawsuits, filed in court, against persons or entities that have failed to comply with statutory or regulatory requirements or with an administrative order.
Penalties
Search for a facility or permit based on when a penalty was last assessed. Select a time frame from the dropdown menu.
 Number of Benchmark Limit Exceedances (3 years) (Industrial Stormwater Only)
Use the dropdown menu to search based on the number of benchmark limit exceedances over the past 3 years. Benchmark monitoring is required under EPA's 2015 Multi-Sector General Permit as an indicator of performance of stormwater control measures. Benchmark limit exceedances indicate instances when stormwater pollutant concentrations exceed levels that could adversely affect receiving water quality, and require permittees to review their stormwater control measures and take corrective action. These exceedances are not violations, but rather indicators of potential problems at the site. For more information on benchmark monitoring, see the Industrial Stormwater Monitoring and Sample Guide under the Industrial Stormwater Fact Sheets and Guidance tab.

Demographic Profile

Advanced/Government Search Icon EJ Indexes Above 80th Percentile (Biosolids Only)
Identify facilities located in Census block groups in the 80th or higher national percentile of one or more of the primary environmental justice (EJ) indexes of EJSCREEN, EPA's screening tool for EJ concerns. Select the number of indexes in the 80th or higher national percentile using the slider. There are currently 11 environmental indexes in EJSCREEN. EPA uses EJSCREEN as a screening tool to identify geographic areas that may warrant further consideration or analysis. Note that use of this filter does not designate an area as an “EJ community” or “EJ facility.” EJSCREEN provides screening level indicators, not a determination of the existence or absence of EJ concerns. For more information, see the EJSCREEN home page.
Advanced/Government Search IconPercent Minority (3-mile radius) (Biosolids Only)
Choose a percentage threshold to search for facilities based on the racial composition of the surrounding three-mile radius. The field is calculated by subtracting the number of persons who are white (and not of Hispanic origin) from the total persons. This number is then divided by the total persons and multiplied by one hundred to determine the percentage.
Advanced/Government Search IconPopulation Density (Biosolids Only)
Identify facilities within high or low density (POPDENS) areas according to the 2010 US Census data: No Restriction; >100; >500; >1,000; >3,000; >5,000; >10,000; or >20,000. This field is the ratio of total persons to total land area (in square miles).

Environmental Conditions

Discharging into Impaired Waters (Industrial Stormwater Only)
Limit your search to permits discharging directly into category 4 or 5 impaired waters. The impaired waters search flag includes facilities that discharge into an impaired water body for which a plan has not yet been developed - these are listed waters under the CWA section 303(d) program (category 5 water body) – as well as facilities that discharge to an impaired water body for which the state has developed a plan to return the water to its designated uses - under the Total Maximum Daily Loads (TMDL) program (category 4 water body). “Any” is selected by default and places no restrictions on the search. Select “Yes” to identify facilities that are discharging into impaired waters or “No” to exclude facilities that are discharging into impaired waters.
Under section 303(d) of the CWA, states, territories, and authorized tribes are required to develop lists of impaired waters. These are waters for which technology-based regulations and other required controls are not stringent enough to meet the water quality standards set by states. The law requires that states establish priority rankings for waters on the lists and develop Total Maximum Daily Loads (TMDLs) , for these waters. A TMDL is a calculation of the maximum amount of a pollutant that a water body can receive and still safely meet water quality standards. For more information about impaired waters or TMDLs, please visit EPA's overview of impaired waters and Total Maximum Daily Loads Program webpage . For detailed information on the categorization of impaired waters, see Section V of the 2006 Integrated Report Guidance .
  • 5. Impaired - TMDL needed. Available information indicates that at least one designated use is not being supported and a TMDL is needed (also known as the 303(d) listed waters).
  • 4. Impaired - TMDL not needed. Available information indicates that at least one designated use is not being supported, but a TMDL is not needed (see subcategories).
  • 4a. TMDL completed. A TMDL has been completed, but impairment still exists.
  • 4b. TMDL alternative. Impairment is being addressed by a method other than a TMDL (e.g., stream bank improvements).
  • 4c. Non-pollutant causes. Cause of impairment is not a pollutant (e.g., habitat destruction).
Note that locational data (latitude and longitude) are needed to index NPDES permits to the National Hydrography Dataset (NHD) Reach Address Database (RAD) . For some facilities, locational data are not available, so whether the facilities directly discharge into impaired waters cannot be determined.
For information on the completeness of 305(b) and 303(d) impairment data by state, see the Office of Wetlands, Oceans, and Watersheds' NHD Reach Indexing Status by State page.
Discharging Pollutants Potentially Contributing to Impairment (Industrial Stormwater Only)
Search for NPDES permits having limits or monitoring requirements for pollutants  with the potential to contributing to the impairment of local waterbodies. EPA compiled a list of pollutants in ICIS-NPDES that may be associated with each ATTAINS impairment cause group. See the Impairment Group Parameter Crosswalk (CSV) (148 K) for the complete list of pollutants.
