Community
Environmental Justice
To search for facilities located in areas with potential environmental justice concerns, select the standard criterion "Potential Environmental Justice Concerns." Users familiar with EJScreen are invited to customize the combination of criteria.
EPA uses EJScreen as a screening tool to identify geographic areas that may warrant further consideration or analysis. Note that use of these criteria 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 environmental justice concerns. For more information, see the EJScreen home page.
Potential Environmental Justice Concerns (All Media Programs, Air, Wastewater, Hazardous Waste)
Find facilities that have at least one EJScreen supplemental index at or above the 90th percentile for the US or state, within the facility's Census block group or averaged over a 1-mile radius around it; or are on tribal land, or in a U.S. territory. EPA's Office of Enforcement and Compliance Assurance uses this indicate to identify facilities that may need additional consideration for environmental justice concerns.
Custom
Find facilities located in areas meeting the selected combination of customized search criteria. Note that the default settings match the criteria for "Potential Environmental Justice Concerns." Selecting more than one value for a criterion will return facilities that meet either value.
- Number of Indexes At or Above 90th Percentile: Select the number of EJScreen indexes at or above the 90th percentile.
- Compare to: Choose "US" or "State" to search for percentile values for EJ indexes nationwide or relative to Census block groups within the same state. The default is US.
Based On: Choose one or more of:
- "Census Block Group" to search for percentile values based on the Census block group the facility is located in.
- "1-mile Average" to search based on the percentiles of EJScreen indexes averaged over a 1-mile radius around the facility.
- "1-mile Maximum" to search based on the highest EJScreen index anywhere within 1 mile of the facility.
The default selections are Census block group and 1-Mile Average.
- Index Type: Choose one of two methodologies for calculating EJScreen indexes. The indexes are a combination of environmental and socioeconomic information. The Environmental Justice Index uses a two-factor demographic index that averages Percent Low Income and Percent People of Color Populations. The Supplemental Index uses a five-factor demographic index that averages Percent Low Income, Percent Unemployed, Percent Limited English Speaking, Percent Less than High School Education, and Low Life Expectancy. The default is Supplemental Index.
- Include all facilities in Indian country: When "Yes" is selected, your search results will also include facilities identified as being located within Indian Country. Identification is based on association with the available geospatial coordinate data, as well as information entered in EPA's Integrated Compliance Information System (ICIS), Resource Conservation and Recovery Act Information (RCRAInfo), Facility Registry Service (FRS), Safe Drinking Water Information System (SDWIS).
- Include all facilities in US territories: When "Yes" is selected, your search results will also include facilities located in United States territories.
Demographics
Percent People of Color (3-mile radius) (All Media Programs, Air, Wastewater, Hazardous Waste)
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. The data source is the ACS 5-year Summary.
Percent Low Income (3-mile radius) (All Media Programs, Air, Wastewater, Hazardous Waste)
Choose a percentage threshold to search for facilities based on the percent of the population of the surrounding three-mile radius that have an income less than two times the poverty level, based on the ACS 5-Year Summary.
Indian Country/Tribal Land
When “Yes” is selected, your search results will be limited to facilities or permits flagged as being located in Indian country, based on information entered in EPA's Integrated Compliance Information System (ICIS). The accuracy and completeness of this information varies by system, and may differ from the FRS Tribal Land Code. “Indian country” is defined by statute at 18 U.S.C. 1151 to include all lands within Indian reservations, dependent Indian communities, and allotted lands. When “No” is selected, your search results will exclude any facilities or permits that are located in Indian country. “ANY” will not restrict search results.
FRS Tribal Land Code (All Media Programs, Air, Wastewater, Hazardous Waste)
When “YES” is selected, your search results will be limited to facilities or permits flagged as being located in Indian country, based on information that has been entered in EPA’s Facility Registry Service. The accuracy and completeness of this information varies by data system. “Indian country” is defined by statute at 18 U.S.C. 1151 to include all lands within Indian reservations, dependent Indian communities, and allotted lands. When “NO” is selected, your search results will exclude any facilities or permits that are located in Indian country. “ANY” will not restrict search results.
On or Near Spatial Tribal Boundary (All Media Programs, Air, Wastewater, Hazardous Waste)
Search for facilities that are located on or near tribal land. Search is based on EPA comparison of the facility locations in its Facility Registry Service to the U.S. Census Bureau 2010 tribal boundary layer data for tribes in the lower 48 states and Bureau of Land Management Alaska State Office data for tribes in Alaska. When “Within X miles” is selected, your search results will be limited to facilities or permits on tribal land and within the selected radius. “No Restrictions” is selected by default and does not restrict search results. You can focus your search on a specific tribal land using the “Tribes” criteria. Please note that facilities must have locational data (latitude/longitude) in EPA's Facility Registry Service to be included in this search. Data Quality Caveat
Tribes (All Media Programs, Air, Wastewater, Hazardous Waste)
Search for facilities located on or near a tribe, based on spatial/locational association. The information is based on EPA comparison of facility coordinates (in Facility Registry Service) to the U.S. Census Bureau 2016 tribal boundary layer data for tribes in the lower 48 states, and Bureau of Land Management Alaska State Office data for tribes in Alaska. Please note that facilities must have locational data (latitude/longitude) in EPA's Facility Registry Service to be included in this search. Data Quality Caveat.
Selection must be made in conjunction with the “On or Near Spatial Tribal Boundary” criteria. "No Restrictions" is selected by default and does not restrict search results. Enter at least one character. Select a tribe from the dropdown list to add it to the search criteria selected panel and clear the input field for a new value.
Tribes (Drinking Water)
Search for drinking water systems located on a particular tribal land. Tribe names are maintained in SDWIS. Enter at least one character in the Tribes text box. Select a Tribe from the dropdown list to add it to the search criteria selected panel and clear the input field for a new value. Multiple selections are allowed; however, users may only select one value at a time from the dropdown list.
When “YES” is selected, your search results will be limited to facilities or permits where the tribe has primary enforcement responsibility over the operations of the facility from the EPA’s Facility Registry Service based on information that has been entered in EPA national program data systems of record. The accuracy and completeness of this information varies by system. “Indian country” is defined by statute at 18 U.S.C. 1151 to include all lands within Indian reservations, dependent Indian communities, and allotted lands. When “NO” is selected, your search results will exclude any facilities or permits that are located in Indian country. “ANY” will not restrict results.
For more information on primacy, see the Primary Enforcement Responsibility for Public Water Systems page.
Indian Country/Tribal Land, Find Facilities That Match (All Media Programs, Air, Wastewater, Hazardous Waste)
When "All Tribal Options" is selected, your search results will return facilities that matches on all selected Indian Country/Tribal Land search criteria. When "Any Tribal Option" is selected, your search results will return facilities that matches on any of the Indian Country Land search criteria selected. These options are not enabled until two or more Indian Country/Tribal Land search criteria are selected.
Data Quality Caveat : EPA makes no claims regarding the accuracy or precision of data concerning Indian country locations or tribal 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 Lower 48 Tribal Areas, Alaska Native Villages, or Alaska Native Allotments. The Indian country and tribal boundary locations are suitable only for general spatial reference and do not necessarily reflect EPA's position on any Indian country locations or tribal 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 2016 tribal boundary layer data when developing environmental data query responses for tribes in the lower 48 United States and the Bureau of Land Management Alaska State Office when developing environmental data query responses for tribes in Alaska. 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 Name (All Media Programs, Air, Wastewater, Hazardous Waste)
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, to search on multiple facility names, separate them with a semicolon in the text box. This search allows data entry of up to 2,500 characters.
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 media program search type (e.g., the All Media Programs 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”.
Note: "Stop Words" are common terms which are excluded from the name search logic in order to retrieve more relevant results. These include: AND, OR, BT, INC, INCORPORATED, LLC, CORP, CORPORATION, LTD, COMPANY, and CO.
- 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.
Search for systems by name or partial name. Be sure to try all possible variations of a system's name. For example, if an abbreviation does not work, try using whole words (i.e., International Metals Company instead of INMETCO). The order of the words in a system name does not affect the search results. To search on multiple system names, separate them with a semicolon in the text box.
Facility ID Number (All Media Programs, Air, Wastewater, Hazardous Waste, Drinking Water)
Search for facilities or permits by EPA Registry ID (i.e., FRS ID) or by the Program System ID (CWA, CAA, SDWA, or RCRA). Allows data entry of up to 2,000 IDs pasted from spreadsheet column, or comma- or return-separated.
Use the "Registry ID" option to search for the IDs entered, as well as all related IDs linked through FRS. All regulatory program systems IDs can be searched from the All Media Programs Facility Search.
Use the "Program System ID" option to search only for the ID(s) entered into the text box. If "Program System ID" is selected, it will search for IDs within the selected Facility Search Type (e.g., searches for matching ICIS-Air IDs when conducting an Air Facility Search). "Program System ID" is selected by default for the Air, Wastewater, and Hazardous Waste searches. Program System IDs by media program search type include:
- ICIS-Air, CAMDBS, TRI, RMP, eGGRT, CEDRI, EIS IDs (Air Facility Search)
- NPDES ID (Wastewater/Stormwater/Biosolids Facility Search)
- Handler ID (Hazardous Waste Facility Search)
- PWS ID (Drinking Water Facility Search)
The Air, Wastewater, and Hazardous Waste searches allow entry of partial ID numbers with at least two characters. Entry of partial IDs will return facilities with ID numbers in any program that begin with the search term.
Note that active/operating facility or permit status is selected by default on the search form. If facility IDs 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. To prevent this, remove the active/operating default selection by using the "X" in the Search Criteria Selected box.
A unique identifying code for a public water system in SDWIS. It consists of a two-letter state or region code, followed by seven digits.
SIC Code (All Media Programs, Air, Wastewater, Hazardous Waste)
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. To search on multiple codes, separate them with a comma in the text box.

Search for NPDES IDs by likely Effluent Guidelines Point Source Category. Users may select a category from the drop-down menu.
Point Source Categories are industry categories that facilities are grouped in based on the release of pollutants from discrete point sources. Point source category classification is based on a facility's primary Standard Industrial Classification (SIC) code in EPA's national program data system ICIS-NPDES. Searching on point source category will only return records for facilities that 1) have a primary SIC code in ICIS-NPDES, and 2) have an SIC code that maps to a point source category.
NAICS Code (All Media Programs, Air, Wastewater, Hazardous Waste)
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. To search on multiple codes, separate them with a comma in the text box.
- Find NAICS Code by Keyword - Search for 2- to 6-digit NAICS codes by keyword. Enter at least one character. Select a NAICS code from the dropdown list to add it to the search criteria selected panel and clear the input field for a new value. Multiple selections are allowed using the dropdown list.

Note: The Facility Type and Owner/Operator selections on the search page are mutually exclusive (i.e., users are able to search by Facility Type or by Owner/Operator, but not both). Selecting a value from one of these criteria will reset the other to "No Restrictions."
- Yes - Returns any NPDES facility or activity classified as such by the regional administrator, or in the case of approved state programs, the regional administrator in conjunction with the state Director. EPA defined "major" in guidance and policy developed in the mid- 1980s. For industrial facilities, EPA developed a permit rating worksheet used by permit writers to assist with classification of a facility as a major or non-major. Worksheets were developed to guide this process. See EPA NPDES Permit Rating worksheet (PDF) (44pp, 1870 K). Industrial facilities that scored 80 points or higher using the worksheet were classified as major facilities. Publicly owned treatment works (POTWS) with 1 million gallons of flow per day or greater and POTWs serving a population of 10,000 or greater were also classified as major facilities.
- No - Returns municipal and industrial facilities that have not been designated as majors.
- Any - Selecting "Any" will return both major and non-major facilities. "Any" is selected by default.
Search for a facility or permit by permit status. The Permit Status values reflect the stages in the permit life cycle.

NPDES Individual Permit, and General Permit Covered Facility are selected by default. "Any" does not restrict search results.
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. Note that only "active" outfalls with a characteristic code of CSO or TCS and not closed outfalls (CLS) are included in the Water Facility Search. To view all of the outfalls, navigate to The Office of Water's CSO Inventory download.

- Urban Stormwater - Small Municipal Separate Storm Sewer System (Small MS4) - Additional requirements for small municipal separate storm sewer systems (MS4s), as defined as 40 CFR 122.30-122.37.
A combined sewer system (CSS) is a wastewater collection system owned by a municipality which conveys sanitary wastewater (domestic, commercial, and industrial) and stormwater through a single pipe system to a publicly-owned treatment works. A combined sewer overflow (CSO) is the discharge from a CSS at a point prior to the treatment plant. CSOs are point sources subject to NPDES permit requirements including both technology-based and water quality-based requirements of the Clean Water Act.
Search for facilities based on permit expiration date. You may search for facilities with expired permits, permits that will expire within the year, or permits that will expire in more than a year.
Search for a facility that has permit limits present. Permit limits limit the amount of pollutants a wastewater treatment plant may discharge.
The type of drinking water system.
Public water system (PWS)- A public water system is a system for the provision to the public of piped water for human consumption, which has at least 15 service connections or regularly serves an average of at least 25 individuals at least 60 days out of the year.- Community water system (CWS) - A public water system that serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents (e.g., homes, apartments and condominiums that are occupied year-round as primary residences).
- Non-community water system (NCWS) - A public water system that is not a community water system.
- Non-transient non-community water system (NTNCWS) - A non-community water system that regularly serves at least 25 of the same nonresident persons per day for more than six months per year. A typical example is a school or an office building that has its own water source, such as a drinking water well.
- Transient non-community water system (TNCWS) - A non-community water system that does not serve 25 of the same nonresident persons per day for more than six months per year. A typical example is a campground or a highway rest stop that has its own water source, such as a drinking water well.
- Unknown - The primacy agency did not report the type of system to EPA.
- Non-Public (NP) - A drinking water system reported to the EPA by a primacy agency that does not meet the definition of Public Water System above.
Primary Source Water Type categorizes the primary water source for the public water system. the source of water determines treatment requirements, or other standards. For example, the presences of any surface water sources in a public water system's inventory forces a surface water (SW) classification, even though more groundwater may be supplied than surface water. Any groundwater under the influence of surface water sources in a water system inventory necessitates a Ground Water Under the Influence of Surface Water (GUISW) classification. These higher classifications dictate higher monitoring requirements for the water system and greater public health protection.
- Surface Water - System has a surface source (e.g., river, reservoir, intake).
- Ground Water - System has a groundwater source that is not under the direct influence of surface water (e.g., protected wells) and no surface water or groundwater under the influence of surface water sources.
- Ground Water Under Direct Influence of (UDI) Surface Water - System has a source that provides water under the direct influence of surface water (e.g., unprotected well or springs) and no surface water sources.
- Purchased Surface Water - System purchases water that originates from a surface source (e.g., river, reservoir, intake.
- Purchased Groundwater - System purchases water that originates from groundwater source that is not under the direct influence of surface water (e.g., protected wells) and no surface water or groundwater under the influence of surface water sources.
- Purchased Groundwater UDI Surface Water - System purchases water that originates from a source that provides water under the direct influence of surface water(e.g., unprotected well or springs)and no surface water sources.

For purposes of this search, “major” refers to CAA federally-reportable sources, CWA major permittees, and RCRA treatment, storage, and disposal facilities and large quantity generators. Default is “ANY”.
- Major Emissions - Facilities which meet the definition of a Major source under the 1990 Clear Air Act Amendments. A Major source is one for which actual or potential emissions are above the applicable major source threshold. Major source thresholds for regulated pollutants run from 100 tons down depending on the pollutant toxicity and ambient air quality.
- 80% Synthetic Minor Emissions - All facilities with the potential to emit (PTE) at or above the 80 percent major source threshold, regardless of whether the actual emissions are lower. If a state, local, or tribal agency does not differentiate facilities based on PTE, all synthetic minors are designated as 80% Synthetic Minors (SM-80s). Full CAA compliance evaluations at SM-80s facilities are conducted, at minimum, once every five federal fiscal years.
- Synthetic Minor Emissions - A facility that avoids Major source requirements by accepting permit conditions which limit emissions below major source thresholds.
- Federally Reportable Minor - A Minor source subject to Part 61 National Emissions Standards for Hazardous Air Pollutants (NESHAP). These sources are kept under close scrutiny because the standards are health based, and violation could imperil human health. OR Any Minor source which is subject to a formal enforcement action, including an Administrative Order, or Civil Suit in the past three years; or has an HPV that is unresolved; or is included on a Compliance Monitoring Strategy plan.
- Emissions Classification Unknown - A facility with an unknown classification.
- Other - A facility that is neither a Major nor a Synthetic Minor source.
- Not Applicable - A classification does not apply to a facility.

Under EPA's Petroleum Refinery Sector Rule, petroleum refineries are required to continually monitor the concentration of benzene emissions along their property boundary (i.e. fenceline). Note that a benzene concentration difference is calculated for each two-week sampling period by subtracting the lowest individual monitor reading from the highest individual individual monitor reading. For example, if the highest monitor reading is 12 micrograms per cubic meter (μg/m3), and the lowest monitor reading is 0.8 μg/m3, the benzene concentration difference (ΔC) would be 11.2 μg/m3. An annual average of the benzene fenceline concentration difference is calculated on a rolling basis for the 26 most recent sampling period.
- No Restrictions: The default setting.
- Reports Benzene Fenceline Monitoring Data: Filters results for petroleum refineries that are required to monitor their benzene fenceline data.
- Exceeds Most Recent Annual Average Benzene (Concentration Change): Filters results for petroleum refineries which have reported a monitoring value that exceeds the most recent annual average benzene concentration change.
- Exceeds Most Recent Sampling Period Benzene (Concentration Change): Filters results for petroleum refineries that reported a monitoring value that exceeds the most recent two-week sampling period concentration change.
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.

Compliance Status (All Media Programs, Wastewater, Hazardous Waste)
All Media Programs
Search by overall compliance status across the program systems. Use the dropdown to select the compliance status of interest:
- Any Violation - search for facilities with any type of violation, including significant violations, in the most recent quarter.
- Significant Violation - search for facilities that have been determined to be in more severe noncompliance for the most recent quarter (air high priority violator, water/hazardous waste significant noncompliance, drinking water enforcement priority).
- Multiple Significant Violations - search for facilities that have been determined to be in more severe noncompliance for two or more programs (air, wastewater, hazardous waste, drinking water) in the most recent quarter.
The Compliance Status search offers flexibility in finding facilities with particular types of violations. Program system-generated codes are categorized in the "basic" view and listed individually in the "advanced" view. To switch between the two views, click the "View More/Less Options" toggle just above the search form. Users may search on more than one compliance status. To search on multiple compliance statuses, select one value at a time from the dropdown list. Users may combine criteria from both the advanced and basic view. In Google Chrome, the Compliance Status criteria can be selected from a list. In Internet Explorer, the criteria can be selected from a dropdown menu.- No Restrictions - does not restrict search results.
- Significant/Category I Noncompliance - 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: Compliance Schedule Violations, Effluent Exceedance Monthly, Effluent Exceedance Non-monthly, Compliance Schedule Non-receipt, Discharge Monitoring Report Non-receipt)
- Violation/Category II Noncompliance - 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.
- New Violations - Violations identified or continuing after the end date of the most recent Quarterly Noncompliance Report (QNCR) (e.g., new or ongoing violations in "Quarter 13" of the Detailed Facility Report compliance history table). These data are considered draft and have not been fully quality assured. The QNCR description is provided in the Detailed Facility Report Data Dictionary .
- No Violation Identified - No known violation recorded in the current quarter.
- Not Applicable - Compliance status does not apply to permits with a status of "Pending", "Not Needed", or "Terminated", or with a permit type of "Unpermitted".
- Significant/Category I Noncompliance
- Compliance/Permit Schedule - Reporting - Compliance schedule non-receipt.
- Compliance/Permit Schedule - Violations - An enforcement action has been issued, and the facility is not meeting its compliance schedule.
- Effluent - Monthly Average Limit - The facility has exceeded the monthly effluent restrictions established by a state or EPA on quantities, rates, and concentrations in wastewater discharges.
- Effluent - Non-monthly Average Limit - The facility has exceeded the non-monthly effluent restrictions established by a state or EPA on quantities, rates, and concentrations in wastewater discharges.
- Failure to Report DMR - Not Received - Discharge Monitoring Report (DMR) not received.
- Violation/Category II Noncompliance
- Reportable Noncompliance - Reportable Noncompliance.
- Other Violation - The facility has effluent, compliance schedule, permit schedule, or single-event violations in the current quarter; however, is not considered to be in RNC or SNC.
- New Violation - Effluent exceedances reported after the last Quarterly noncompliance Report (QNCR) was issued. These data are considered draft and have not been fully quality assured. A QNCR description is provided in the Detailed Facility Report Data Dictionary .
- No Violation Identified - Indicates no violation recorded in the current quarter.
- Blank - No Violations - No violation recorded in the current quarter.
- Resolved - The facility has returned to compliance with its permit conditions, either with or without issuance of an enforcement action.
- Resolved - Pending - An enforcement action has been issued, and facility compliance with the action is pending final completion.
- Unknown/Undetermined - No Data - EPA's data system is not able to determine the facility-level compliance status because the system has not been set to track it or the data haven't been entered. This information may be available from a state database.
- Violations Manually Overridden - Not considered in RNC/SNC based on manual review of data by state or EPA region.
- Not Applicable - Compliance status does not apply to permits with a status of "Pending", "Not Needed", or "Terminated", or with a permit type of "Unpermitted".
- Significant/Category I Noncompliance
Hazardous Waste
Select one or more of the following options to search by RCRA compliance status.- No Restrictions - does not restrict search results.
- Significant Noncomplier - A RCRA site is considered to be a Significant Noncomplier when there is actual exposure or a substantial likelihood of exposure to hazardous waste/constituents, is a chronic or recalcitrant violator; or a substantial deviation from the terms of a permit, order, agreement, or RCRA statutory or regulatory requirements.
- Noncomplier - When a RCRA site is in any violation that is not considered to be a Significant Noncomplier. See Violation Type for more information on violations.
- No Violation Identified - Returns RCRA sites that have no current violations. Selecting this option disables the selection of Violation Type and Number of Current Violations.
Search for a facility based on the type of recent violation. "No Restrictions" does not further restrict search results. Recent violations include:
- all unresolved enforcement actions involving high priority violations (HPVs); and
- any federally-reportable violations (FRVs) with a determination date in the last four quarters.
"Unresolved" means that the enforcement action is not concluded; it does not necessarily mean that the violation is still ongoing. Enforcement agencies can elect to report the dates the violation actually ends, but are not required to do so. EPA no longer tracks compliance status for FRVs, so the "recent violations" search instead uses the FRV determination date.
Search for RCRA sites that are in violation for the selected violation types. Violation type selections apply to the facility's current compliance status.
Enter at least one character. Select a Violation Type from the dropdown list to add it to the search criteria selected panel and clear the input field for a new value. Multiple selections are allowed using the dropdown list.

Select systems with violations that are unresolved (neither corrected nor addressed) or that may have occurred, based on the latest date that EPA knows the compliance status. EPA does not generally know the exact date of a violation, but only the compliance period during which each violation took place, so this actually searches for the types of violations from the latest quarter of compliance or the last date on which the state reported any activities (whichever is later). "No Restrictions" does not restrict search results.
- Enforcement Priority - A public water system with unresolved serious, multiple, and/or continuing violations, as identified by the quarterly application of EPA's Drinking Water Enforcement Response Policy (PDF) (16 pp, 952 K, About PDF ), that must either return to compliance or be addressed by a formal enforcement action within six months.
EPA designates enforcement priority so that the drinking water system and the primacy agency will act quickly to resolve the most significant drinking water violations. Many public water systems with violations, however, are not designated as enforcement priority. Operators and the primacy agencies are expected to correct the violations at non-enforcement priority violators as well, but without imposition of the deadlines applicable to enforcement priority systems. If the violations at a non-enforcement priority violator are left uncorrected, that system may become an enforcement priority. When a system designated as enforcement priority has returned to compliance or has been addressed by a formal enforcement action, it is no longer designated an enforcement priority. EPA updates its enforcement priority list on a quarterly basis. - Health-Based Violations - Violations of maximum contaminant levels (MCLs) or maximum residual disinfectant levels (MRDLs), which specify the highest concentrations of contaminants or disinfectants, respectively, allowed in drinking water; or of treatment technique (TT) rules, which specify required processes intended to reduce the amounts of contaminants in drinking water. MCLs, MRDLs, and treatment technique rules are all health-based drinking water standards.
- Monitoring and Reporting Violations - Failure to conduct regular monitoring of drinking water quality, as required by SDWA, or to submit monitoring results in a timely fashion to the primacy agency.
- Public Notice Violations - Violations of the public notification requirements of SDWA, which require systems to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
- Other Violations - Violations of other requirements of SDWA, such as issuing annual consumer confidence reports or maintaining required records.
- New Violations Only (Unofficial) - Violations that have been reported to SDWA since end of the last official quarter. These violations are considered draft and do not reflect the official compliance status for the facility.
- No Violations - EPA does not know of any unresolved violations for this system.
- Enforcement Priority - A public water system with unresolved serious, multiple, and/or continuing violations, as identified by the quarterly application of EPA's Drinking Water Enforcement Response Policy (PDF) (16 pp, 952 K, About PDF ), that must either return to compliance or be addressed by a formal enforcement action within six months.

Enforcement Actions
There are many enforcement action types (also called "tools") available to EPA enforcement and compliance assurance programs. Some tools are used to notify regulated entities regarding potential violations (e.g., Warning Letter, Notice of Non-Compliance). Others are used to advise regulated entities of an impending enforcement action and invite settlement (e.g., Notice of Violation, Show Cause Letter, Pre-Filing Notice Letter, and Notice of Intent to File an Administrative Complaint). Others are the actual enforcement action (e.g., Administrative Penalty Order, Administrative Compliance Order).
Search for a facility or permit based on an informal enforcement action issued to the facility. To specify your date range, select either “Within” or “None Within” and use the dropdown 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.
The full informal enforcement action definition is provided in the Detailed Facility Report Data Dictionary.

For a public water system that has conducted a sanitary survey within five years, search for public water systems with or without significant deficiencies within the past five years or within the last survey completed or within the most recent survey activity.
All public water systems are required to be evaluated by a sanitary survey every three to five years. A sanitary survey is an on-site review of a system's water source, treatment, distribution system, storage, pumps, monitoring and reporting, management and operation, and operator compliance, and intended to point out sanitary deficiencies and assess the system’s capability to supply safe drinking water.
Nonattainment Area for Any Pollutant (All Media Programs, Air)
Search for facilities that are located in a nonattainment area for which EPA has developed GIS shapefiles. A nonattainment area is an area that does not meet one or more of the National Ambient Air Quality Standards for six commonly found air pollutants ("criteria pollutants") designated in the Clean Air Act: particle pollution (often referred to as particulate matter), ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Nonattainment areas for the following standards are currently included in ECHO:
- Ozone 8 hr (1997 Standard)
- Ozone 8 hr (2008 Standard)
- Ozone 8 hr (2015 Standard)
- Carbon Monoxide (1971 Standard)
- Lead (1978) Standard)
- Lead (2008 Standard)
- PM 2.5 (1997 Standard)
- PM 2.5 (2006 Standard)
- PM 2.5 (2012 Standard)
- PM 10 (1987 Standard)
- Nitrogen Dioxide (1971 Standard)
- Sulfur Dioxide (1971 Standard)
- Sulfur Dioxide (2010 Standard)
“No Restrictions” is selected by default and places no restrictions on the search. Select “Nonattainment Status” to identify facilities located within an area where air pollution levels persistently exceed the U.S. National Ambient Air Quality Standards (NAAQS). Select "Nonattainment or Maintenance Status" to identify facilities located in a nonattainment or maintenance nonattainment area, or "None" to exclude facilities located in a nonattainment or maintenance nonattainment area.
Discharging into Impaired Waters (All Media Programs, Wastewater)
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). “No Restrictions” 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.
Causes of Impairment(s) by Group(s) (ATTAINS) (Wastewater Only)
Search for NPDES permits by pollutant impairment groups as maintained in the ATTAINS database. See the Impairment Group Parameter Crosswalk (CSV) (148 K) to derive the list of cause groups.
Discharging Pollutants Potentially Contributing to Impairment (Wastewater Only)
Search for NPDES permits having limits or monitoring requirements for pollutants with the potential to contributing to the impairment of local water bodies. 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.

- CERCLA Hazardous Substances - Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) hazardous substances are substances that are considered severely harmful to human health and the environment. Many are commonly used substances which are harmless in their normal uses, but are quite dangerous when released. They are defined in terms of those substances either specifically designated as hazardous under the Superfund law, or those substances identified under other laws. Superfund's definition of a hazardous substance includes the following:
- Any element, compound, mixture, solution, or substance designated as hazardous under section 102 of CERCLA.
- Any hazardous substance designated under section 311(b)(2)(a) of the Clean Water Act (CWA), or any toxic pollutant listed under section 307(a) of the CWA. There are over 400 substances designated as either hazardous or toxic under the CWA.
- Any hazardous waste having the characteristics identified or listed under section 3001 of the Resource Conservation and Recovery Act. Any hazardous air pollutant listed under section 112 of the Clean Air Act, as amended. There are over 200 substances listed as hazardous air pollutants under the Clean Air Act (CAA).

- Radionuclides - All parameters measuring specific radionuclides such as Uranium and Radium isotopes, as well as radioactivity not specific to a particular isotope, including gross alpha and gross beta radiation.
- Color - All parameters measuring color in wastewater. Color measurements may be reported using a variety of units, such as Platinum Cobalt (Pt-Co) units or pound/ton produced.
- Whole Effluent Toxicity - Parameters measuring Whole Effluent Toxicity (WET) in wastewater. WET refers to the aggregate toxic effect to aquatic organisms from all pollutants contained in a facility’s wastewater.
- Per- and Polyfluoroalkyl Substances (PFAS) - PFAS are a group of man-made chemicals that includes Perfluorooctanoic acid (PFOA), Perfluorooctane Sulfonate (PFOS), GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. The chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects.
