40 CFR Appendix A to Part 127 - Appendix A to Part 127—Minimum Set of NPDES Data

The following two tables identify the minimum set of NPDES data that authorized states, tribes, territories must enter or transfer to EPA's national NPDES data system as well as what NPDES-regulated entities must electronically report to the designated initial recipient (authorized NPDES program or EPA) [see 40 CFR 127.2(b)]. Authorized NPDES programs will be the data provider in the event the regulated entity is covered by a waiver from electronic reporting. Use of these two tables ensures that there is consistent and complete reporting nationwide, and expeditious collection and processing of the data, thereby making it more accurate and timely. Taken together, these data standardizations and the corresponding electronic reporting requirements in 40 CFR parts 3, 122, 123, 124, 125, 127, 403, and 503 are designed to save the NPDES authorized programs considerable resources, make reporting easier for NPDES-regulated entities, streamline permit renewals (as permit writers typically review previous noncompliance events during permit renewal), ensure full exchange of NPDES program data between states and EPA to the public, improve environmental decision-making, and protect human health and the environment.

Authorized NPDES programs may also require NPDES regulated entities to submit more data than what is listed in this appendix. The authorized NPDES program can require NPDES regulated entities to submit these “non-appendix A” data on paper, electronically, or attachments to electronic notices and reports filed in compliance with this part.

Instructions: Table 1 of this appendix provides the list of data sources and minimum submission frequencies for the ten different NPDES Data Groups. Table 2 of this appendix provides the data that must be electronically reported for each of these NPDES Data Groups. The use of each data element is determined by identifying the number(s) in the column labeled “NPDES Data Group Number” in Table 2 and finding the corresponding “NPDES Data Group Number” in Table 1. For example, a value of “1” in Table 2 means that this data element is required in the electronic transmission of data from the NPDES program to EPA (Core NPDES Permitting, Compliance, and Enforcement Data). Likewise, a value of “1 through 10” in Table 2 means that this data element is required in all ten NPDES data groups. NPDES regulated entities that have no historical record (e.g., “greenfield” facilities) do not need to provide data elements that rely on historical data elements. For the purposes of this appendix, the term `sewage sludge' [see 40 CFR 503.9(w)] also refers to the material that is commonly referred to as `biosolids.' EPA does not have a regulatory definition for biosolids but this material is commonly referred to as sewage sludge that is placed on, or applied to the land to use the beneficial properties of the material as a soil amendment, conditioner, or fertilizer. EPA's use of the term `biosolids' in this appendix is to confirm that information about beneficially used sewage sludge (a.k.a. biosolids) is part of the data collected in this appendix.

1 Entities regulated by a NPDES permit will comply with all reporting requirements in their respective NPDES permit.

2 Use the “NPDES Data Group Number” in this table and the “NPDES Data Group Number” column in Table 2 of this appendix to identify the source of the required data entry. The EPA notes that electronic systems may use additional data to facilitate electronic reporting as well as management and reporting of electronic data. For example, NPDES permittees may be required to enter their NPDES permit number (“NPDES ID”—NPDES Data Group 1 and 2) into the applicable electronic reporting system in order to identify their permit and submit a Discharge Monitoring Report (DMR—NPDES Data Group 3). Additionally, NPDES regulated entities may be required to enter and submit data to update or correct erroneous data. For example, NPDES permittees may be required to enter new data regarding the Facility Individual First Name and Last Name (NPDES Data Group 1 and 2) with their DMR submission when there is a facility personnel change.

3 The applicable reporting frequency is specified in the NPDES permit or control mechanism, which may be more frequent than the minimum frequency specified in this table.

Compliance Monitoring Activity Information (Data Elements Specific to Sewer Overflow/Bypass Event Reports)
[Note: These data elements apply to sewer overflows and bypass events at POTWs. These data elements do not apply to industrial facilities. This report uses the `Permitted Feature Identifier (Compliance Monitoring Activity)' data element to identify the location of each sewer overflow or bypass at a permitted feature. Each bypass location should be permitted and have an identifier in the `Permitted Feature Identifier (Permit)' data element. This report will also identify the location of each sewer overflow at an unpermitted feature.]
Sewer Overflow/Bypass Identifier	This data element will allow the reporting of multiple sewer overflows or bypasses on one report. Each individualized sewer overflow or bypass will be given a unique identifier (e.g., 1, 2, 3, and so on) for each Sewer Overflow/Bypass Event Report. This field can be system generated to accommodate one or more individual sewer overflows or bypasses. If the sewer overflows are caused by an extreme weather event (e.g., hurricane) that floods the entire sewer system the POTW can use this data element to indicate that the number of sewer overflows cannot be tabulated as they are too numerous to count	122.41(l)(4), (6), and (7) and 122.41(m)(3)	3, 9.
Sewer Overflow Longitude for Unpermitted Feature (Sewer Overflow/Bypass Event Report)	This data element is required for each Sewer Overflow/Bypass Identifier without a corresponding identifier in the `Permitted Feature Identifier (Permit)' data element, which is reported on the NPDES permit application or Notice of Intent for NPDES permit coverage. This data element is the measure of the angular distance on a meridian east or west of the prime meridian for the sewer overflow location. The format for this data element is decimal degrees (e.g., −77.029289) and the WGS84 standard coordinate system. The `Permitted Feature Identifier (Compliance Monitoring Activity)' data element is used to identify the location of each sewer overflow at a permitted feature. If the sewer overflow is associated with a private residence the longitude of the nearest collection system structure (e.g., manhole) can be used for this data element to the extent that reporting is required. The POTW can leave this data element blank on the Sewer Overflow/Bypass Event Report if the sewer overflows are caused by an extreme weather event (e.g., hurricane) that floods the entire sewer system and are too numerous to count. This data element can also be system generated if the Sewer Overflow/Bypass Event Report collects the street location of the sewer overflow and the street location can be used to generate an accurate longitude value. (Note: “Post Office Box” addresses and “Rural Route” addresses are generally not geocodable)	122.41(l)(4), (6), and (7)	3, 9.
Sewer Overflow Latitude for Unpermitted Feature (Sewer Overflow/Bypass Event Report)	This data element is required for each Sewer Overflow/Bypass Identifier without a corresponding identifier in the `Permitted Feature Identifier (Permit)' data element, which is reported on the NPDES permit application or Notice of Intent for NPDES permit coverage. This data element is the measure of the angular distance on a meridian north or south of the equator for the sewer overflow location. The format for this data element is decimal degrees (e.g., -77.029289) and the WGS84 standard coordinate system. The Permitted Feature Identifier (Compliance Monitoring Activity) data element is used to identify the location of each sewer overflow at a permitted feature. If the sewer overflow is associated with a private residence the latitude of the nearest collection system structure (e.g., manhole) can be used for this data element to the extent that reporting is required. The POTW can leave this data element blank on the Sewer Overflow/Bypass Event Report if the sewer overflows are caused by an extreme weather event (e.g., hurricane) that floods the entire sewer system and are too numerous to count. This data element can also be system generated if the Sewer Overflow/Bypass Event Report collects the street location of the sewer overflow and the street location can be used to generate an accurate longitude value.

(1) The NPDES program authority may pre-populate these data elements and other data elements (e.g., Federal Registry System ID) in the NPDES electronic reporting systems in order to create efficiencies and standardization. For example, the NPDES program authority may configure their electronic reporting system to automatically generate NPDES IDs for control mechanisms for new facilities reported on a Pretreatment Program Report [40 CFR 403.12(i)]. Additionally, the NPDES program authority may decide whether to allow NPDES regulated entities to override these pre-populated data.

(2) The data elements in this table conform to the EPA's policy regarding the application requirements for renewal or reissuance of NPDES permits for discharges from Phase I municipal separate storm sewer systems (published in the Federal Register on August 6, 1996).

(3) The data elements in this table are also supported by the Office Management and Budget-approved permit applications and forms for the NPDES program.

(4) These data will allow EPA and the NPDES program authority to link facilities, compliance monitoring activities, compliance determinations, and enforcement actions. For example, these data will provide several ways to make the following linkages: linking violations to enforcement actions and final orders; linking single event violations and compliance monitoring activities; linking program reports to DMRs; linking program reports to compliance monitoring activities; and linking enforcement activities and compliance monitoring activities.
