Effluent Limit Exceedances Search Results Help

The results table presents information about the facilities that meet the search criteria specified on the Effluent Limit Exceedances Search. The results table allows you to customize, sort, and download data.

The results present facility-level, or if selected, pollutant-level, information about E90 effluent exceedances. Note that if a pollutant or pollutant category is selected from the search criteria, the E90 exceedances counts and pollutant loadings will reflect exceedances associated with the selected criteria and not reflect total facility exceedances.

Facility Characteristics

Major/Minor
A facility classification from NPDES permitting authorities based on factors such as toxic pollutant potential, ratio of discharge flow/stream flow volume, conventional pollutant loading, public health impact, water quality factors, and proximity to coastal waters. EPA places greater priority on major facilities and requires authorized states to provide more information about the compliance status of these dischargers. For more information, please see About Loading Tool Data.
SIC Code
The primary Standard Industrial Classification (SIC) code in ICIS-NPDES. The SIC 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. For more information, see the SIC Lookup.
NAICS Code
Indicates the facility's or permit's primary North American Industry Classification System (NAICS) Code. The NAICS Code has replaced the U.S. Standard Industrial Classification (SIC) system. The system was developed to give special attention to developing production-oriented classifications for (a) new and emerging industries, (b) service industries in general, and (c) industries engaged in the production of advanced technologies.
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. For more information, see the NAICS Lookup.
Permit Status
The Permit Status values reflect the stages in the permit life cycle.
  • 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
Permit Issuer
The environmental agency that administers the permit, typically a state or EPA Region.
Permit Expiration Date
The date the most recently issued permit expires.
Federal Facility
Yes/No field to indicate facilities that are owned and operated by the U.S. government.
Pretreatment Flag
Yes/No field to indicate if the NPDES ID has an approved pretreatment program. For more information, see NPDES Pretreatment.
Tribal Flag
Yes/No field to indicate the facility is located on tribal land. EPA compares the facility location in its 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.

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 AreasAlaska ReservationAlaska 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.

Includes Potential Outliers
Yes/No field to indicate the facility has DMR data that has been flagged as potential outliers or data errors. Y = Yes; Blank = No.
Average Facility Flow (MGD)
The average of the average monitoring period flows (in units of millions of gallons per day) for the reporting year. For example, if a facility reports monthly wastewater flows, the facility average flow is the arithmetic average of the reported monthly wastewater flows.

Enforcement and Compliance

Quarters with Effluent SNC Exceedances
Count of the number of quarters (qtrs) in which the permit had Significant/Category I Noncompliance (SNC) Effluent Exceedances within the selected time period. A quarter is any of the following 3-month calendar periods: January-March, April-June, July-September, or October-December.
Number of Inspections
The number of facility inspections during the selected time period.
Most Recent Inspection
The date of the most recent inspection in ICIS-NPDES.
Number of Formal Enforcement Actions
The number of formal enforcement actions (e.g., administrative orders and judicial cases) during the selected time period.
Most Recent Formal Enforcement Action
The date of the most recent formal enforcement action in ICIS-NPDES.
E90 Facility Total
Count of total effluent exceedances for the NPDES ID over the selected time period. However, if a pollutant(s) or pollutant category is selected in the search criteria, the E90 exceedances counts will reflect total exceedances for the selected pollutant(s) or pollutant category.
E90 for Data Quality Review (Facility Total)
Count of total effluent exceedances with data quality flags (values identified as potential outliers or data errors) for the facility. Use the Effluent Exceedance Report to review each exceedance identified as a potential outlier, indicated by blue flags. To report an error, follow the instructions on reporting errors on Effluent Charts.
E90 Max Outfall Total
Count of total effluent exceedances at the individual outfall with the highest number of exceedances over the selected time period. A NPDES permit may have more than one outfall. If a pollutant(s) or pollutant category is selected in the search criteria, the E90 exceedances counts will reflect total exceedances for the selected pollutant(s) or pollutant category.
E90 Trend
Displays a graphical representation of the number of effluent exceedances over time.
E90 [Year]
The number of E90 exceedances for the facility during each year in the selected year range. Up to five years may be displayed. However, if a pollutant(s) or pollutant category is selected in the search criteria, the E90 exceedances counts will reflect total exceedances for the selected pollutant(s) or pollutant category.

Pollutant Loadings

Pollutant loadings are summed to the facility level unless a pollutant(s) or pollutant category is selected from the search criteria.

Total Pounds
The total pounds of pollutants discharged by the NPDES ID over the selected time period. Pollutant discharge amounts are calculated using DMR concentration, quantity, and flow data from ICIS-NPDES.
Total TWPE (lb-eq)
The total Toxic Weighted Pounds Equivalent (TWPE) discharged by the NPDES ID over the selected time period. TWPE is the mass of a pollutant or chemical discharged that accounts for its relative toxicity. To convert pollutant loadings into TWPE, EPA multiplies the pollutant mass (in pounds) by its toxic weighting factor (TWF).
Note: EPA developed TWFs for use in its Effluent Limitations Guidelines and Standards (ELGs) development program to allow comparison of pollutants with varying toxicities. See Technical Support Documents for more information on TWF values and methodology.
Total Load Over Limit (lb)
Where numeric permit or enforcement action limits are available, the Loading Tool calculates the Load Over Limit. This calculation is done by summing the monitoring period differences between the average load and the limit. For more information, see Hierarchy of Loading Calculations in the Water Pollutant Loading Tool.
Total TWPE Over Limit (lb-eq)
Where numeric permit limits and TWFs are available, the Toxic Weighted Pounds Equivalent discharged over the limit.
[Year] Load Over Limit (lb)
The load over limit for each year in the selected year range. Up to five years may be displayed.
