Note: This field considers the most current data available, including effluent exceedances reported after the last QNCR was issued; post QNCR data are considered draft and have not been fully quality assured. The number of effluent violations reported in the post QNCR data are added to the total number of officially reported exceedances.

Compliance Tracking [CWPComplianceTracking]

Displays the compliance tracking status for a NPDES permit 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.

• 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).

Detailed information on the categorization of waters can be found in Section V of the 2006 Integrated Report Guidance.

Causes of Impairment(s) (ATTAINS) [AttainsStateCauses]

Other Information

EJ Indexes Above 80th Percentile [Over80CountUs]

Indicates the number of primary EJSCREEN environmental justice (EJ) indexes exceeding the 80th or higher national percentile for the Census block group that the facility is located in. EPA uses EJSCREEN as a screening tool to identify geographic areas that may warrant further consideration or analysis. Note that use of this field 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.

EJSCREEN Lead Paint Indicator [PctilePctpre1960Us]

The national percentile of the Lead Paint Indicator Environmental Index for the Census block group that the facility is located within. This index is based on a calculation of housing units built before 1960, based on Census and American Community Service (ACS) data. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

The national percentile of the EJSCREEN National-Scale Air Toxics Assessment (NATA) Cancer Risk Environmental Index for the Census block group that the facility is located within. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN NATA Respiratory Hazard Index [PctileRespUs]

The national percentile of the EJSCREEN National-Scale Air Toxics Assessment (NATA) Respiratory Hazard Environmental Index for the Census block group that the facility is located within. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN Traffic Proximity [PctileTrafficScoreUs]

The national percentile of the EJSCREEN Traffic Proximity Environmental Index for the Census block group that the facility is located within. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN Wastewater Discharge Proximity [PctileProximityNPDESUs]

The national percentile of the EJSCREEN Major CWA Direct Discharger Proximity Environmental Index for the Census block group that the facility is located within. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN Superfund Proximity [PctileProximityNplUs]

The national percentile of the EJSCREEN National Priorities List (NPL)/Superfund Proximity Environmental Index for the Census block group that the facility is located within. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN RMP Proximity [PctileProximityRmpUs]

The national percentile of the EJSCREEN Risk Management Plan (RMP) Proximity Environmental Index for the Census block group that the facility is located within. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN Hazardous Waste Proximity [PctileProximityTsdfUs]

The national percentile of the EJSCREEN Treatment Storage and Disposal Facilities (TSDFs) Proximity Environmental Index for the Census block group that the facility is located within. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN Ozone [PctileO3Us]

The national percentile of the EJSCREEN Ozone Environmental Index for the Census block group that the facility is located within. This index is an indication of the relative ozone level in the air. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

EJSCREEN PM 2.5 [PctilePmUs]

The national percentile of the EJSCREEN Particulate Matter (PM) 2.5 Environmental Index for the Census block group that the facility is located within. This index is an indication of the relative fine PM levels in the air. For more information, see EJSCREEN Environmental Indicators and How the EJ Index Works.

Population Density (3 mi) [FacPopDen]

The number of persons per square mile in the profiled area. The ratio of total persons (displayed in the Total Persons field) to total land area (displayed in the Land Area field).

Percent Minority (3 mi) [FacPercentMinority]

Percent Minority is the percentage of the population of the given area that is considered minority. 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.

Statistics are shown for the area within a 3-mile radius of each facility. The radius is measured from the best available lat/long coordinate (normally from EPA's Locational Reference Tables - LRT file). Users should be aware that the Demographic Profile is based upon the reported latitude and longitude of the facility or permit holder. Surrounding populations and other statistics were estimated by retrieving the data for Census block groups within three miles of each facility.

Once facility-level data are displayed (Data Table view or 500 or fewer results in Interactive Map view), the facility summary panel becomes visible. Upon clicking in a table row (or on a map pin), the Facility Summary panel will expand (or update) to present a brief overview of the selected facility’s compliance information. The facility name and street address are displayed at the top of the panel. A miniature map zoomed in on the selected facility is shown below the name and address.

The following data are presented below the map in the Facility Summary panel:

• NPDES Permit
• Compliance Status
• Inspections (5 years)
• Date of Last Inspection
• Quarters with Noncompliance (of 12)

The facility's Effluent Charts page can be accessed by clicking the NPDES Permit hyperlink. The facility's Detailed Facility Report can be accessed by clicking the "More Facility Details" hyperlink on the bottom right of the panel.

Filter Facilities

When using the Interactive Map view, the Filter Facilities panel is enabled once search results are refined to 500 or fewer facilities. Several interactive filters are provided, grouped using the same organizing principles used on the search form. Filters allow you to add an additional layer of analysis within your current search without affecting the universe of results. The counts displayed in the Current Search panel will remain frozen as you manipulate different filters to further analyze the data.

Most filters can be applied by checking a corresponding checkbox. In addition to enabling a filter, several filters also offer further customization by establishing a specific threshold or range of values by using interactive sliders. For sliders that are based on a quantity (versus a timeframe), ECHO dynamically determines the minimum and maximum of the range based on the data included in your search results. Several filters allow you to apply "without" logic by selecting the "No" checkbox.

As you apply filters to your results, ECHO dynamically adjusts the counts in the Filter Facilities panel associated with each. As more filters are selected, the number of facilities that match will decrease. You can select and unselect as many filters as you'd like without affecting your original universe of search results.  

By default, the Only Show Matches is checked. As you apply filters, ECHO dynamically adjusts the map and data table display to only show those facilities that match the filters selected. You can uncheck Only Show Matches to compare the facilities that match, or do not, the filters selected. Facilities that do not match are shown on the map as "dimmed" map pins and rows in the table that do not match are grayed out. Clicking the Clear Filters link in the top right of the panel will remove all selected filters.
