compliance and enforcement status of facilities regulated by the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act (CWA). ICIS-NPDES is designed to support the NPDES program at the state, regional, and national levels.</p><p>ICIS-NPDES records included in the download files are those with any permit status code value for the current permit record. The ICIS-NPDES Master General Permits file include the current and historical permit records. ICIS-NPDES records (for all permit types except Master General Permits) includes the following data types:</p><ul><li>Permit facility data</li><li>Inspection information</li><li>Permit schedule violations</li><li>Effluent violations</li><li>Compliance schedule violations</li><li>Single Event violations</li><li>Enforcement actions</li></ul><p>The violation data includes system-generated records. ICIS automatically generates three basic types of violations: schedule violations, effluent violations, and DMR non-receipt violations. For each of these three types of violations, there are one or two automatic processes that serve to generate the violations. For each type, there is a process that runs when certain data related to requirements or permittee performance are entered or edited. For schedule violations and DMR non-receipt violations, there are also processes that run nightly. In addition to these automatically generated violations, users can manually enter single event violations. The table below lists the specific types of violations that may be generated by ICIS or manually entered.</p><table><thead><tr><th scope="col">Code</th><th scope="col">Violation Type</th><th scope="col">Description</th><th scope="col">Generated by</th></tr></thead><tbody><tr><td>D80</td><td>DMR Non-Receipt</td><td>Required monitoring DMR value overdue</td><td>System</td></tr><tr><td>D90</td><td>DMR Non-Receipt</td><td>Limited value overdue</td><td>System</td></tr><tr><td>E90</td><td>Effluent</td><td>Reported DMR value exceeds maximum or average limit value or is below minimum limit value</td><td>System</td></tr><tr><td>C10</td><td>Schedule</td><td>Schedule event reported late</td><td>System</td></tr><tr><td>C20</td><td>Schedule</td><td>Schedule event achieved late but reported</td><td>System</td></tr><tr><td>C30</td><td>Schedule</td><td>Schedule event not achieved but reported</td><td>System</td></tr><tr><td>C40</td><td>Schedule</td><td>Schedule not achieved and not reported</td><td>System</td></tr><tr><td>Various</td><td>Single Event</td><td>Any manually determined violation</td><td>User</td></tr></tbody></table><p>Limited enforcement action data are provided from ICIS FE&C where a NPDES program interest linkage exists. More detailed information about linked enforcement actions can be obtained from the ICIS FE&C download files, by using the Enforcement Action Identifier (ENF_IDENTIFIER).</p><p class="clear-both text-right margin-bottom-neg-2"><a class="top-of-page" href="#main-content"><span>Top of Page</span></a></p><hr><h2><a name="Guidance"> </a>Guidance on ICIS-NPDES Downloads</h2><p>Only certain data elements from ICIS-NPDES are incorporated into ECHO and a subset of these are provided in the download format. This document contains a list of these data elements, as well as available definitions. The data element table in Section 1.2 presents the ICIS-NPDES data elements in related groups that parallel the data's relationships.</p><p>There are two sets of download data. One ZIP file contains a single comma-separated value file for Effluent Violations (NPDES_EFF_VIOLATIONS.csv); the other ZIP file contains 10 comma-separated value files. Data were selected based on a single criterion: that the ICIS-NPDES Permit Status (PERMIT_STATUS) for the current permit version is equal to any non-null value. The files may contain repeating data fields, which will cause records to repeat the key field(s), e.g., NPDES_ID, where a permit has multiple values of the repeating field(s).</p><p>Key field columns are present in all CSV files and may be used to join and relate data between files. The following table describes how the tables may be joined:</p><table><thead><tr><th colspan="2" scope="col">Key fields</th><th scope="col">Tables</th></tr></thead><tbody><tr><td>1</td><td>NPDES_ID or EXTERNAL_PERMIT_NMBR</td><td><a name="1"></a>All Tables</td></tr><tr><td>2</td><td>REGISTRY_ID or FACILITY_UIN</td><td><a name="2"></a>ICIS_FACILITIES, NPDES_INSPECTIONS, NPDES_INFORMAL_ENFORCEMENT_ACTIONS</td></tr><tr><td>3</td><td>NPDES_VIOLATION_ID</td><td><a name="3"></a>{NPDES_PS_VIOLATIONS, NPDES_CS_VIOLATIONS, NPDES_SE_VIOLATIONS, NPDES_EFF_VIOLATIONS}*, NPDES_VIOLATION_ENFORCEMENTS</td></tr><tr><td>4</td><td>VERSION_NMBR</td><td><a name="4"></a>ICIS_PERMITS, NPDES_EFF_VIOLATIONS</td></tr></tbody></table><p>* NPDES_VIOLATION_ID is a unique identifier for violations in ICIS-NPDES. The ICIS-NPDES data downloads provide violations in four tables by type, and as such, the violations in these tables represent unique records and cannot be joined. However, NPDES_VIOLATION_ID may be used to join to the NPDES_VIOLATION_ENFORCEMENTS table, which describes the EPA civil enforcement action, if any, resulting from a violation.</p><div
