                            Appendix A to Part 127
               [DRAFT FOR SUPPLEMENTAL NOTICE  -  CLEAN VERSION]
                                        
The following two tables identify the minimum set of data that states, tribes, territories, and NPDES-regulated entities must electronically report to the designated initial recipient (NPDES authorized program or EPA) [see 40 CFR 127.2(b)]. 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 3, 122, 123, 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.

Instructions: Table 1 provides the list of data sources and minimum submission frequencies for the ten different NPDES Data Groups. Table 2 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 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.

Note 1: NPDES regulated entities regulated by a NPDES permit will comply with all reporting requirements in their respective NPDES permit. 2
Note 2: Use the "NPDES Data Group Number" in this table and the "NPDES Data Group Number" column in Table 2 to identify the source of the required data entry. 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.
Note 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 Table 1.
Note 4: 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 example, the following data element relies on historical data: Biosolids or Sewage Sludge Amount (Permit) - The amount of biosolids (in dry metric tons) produced by the permitted facility in the preceding 365-day period for each different type of biosolids and sewage sludge generated by the facility. 
Note 5: For the purposes of this Appendix, biosolids refers to treated or processed domestic sewage sludge.
Note 6: Authorized states will be the data provider in the event an event where the regulated entity is covered by a waiver from electronic reporting.

Construction and Industrial Stormwater Information (from the permitting authority derived from the NPDES Permit Application, Notice of Intent, or No Exposure Certification, or Low Erosivity Waiver)
Permit Required by Residual Designation
The permit writer may designate additional stormwater discharges as requiring
NPDES permits when the stormwater discharge, or category of stormwater discharges within a geographic area, contributes to a violation of a water quality standard or is a significant contributor of pollutants to waters of the United States. This data element identifies whether the permit writer is using this authority, commonly referred to as the "Residual Designation" authority, to regulate stormwater discharges through a NPDES permit.

Residual Designation Determination Date
The date when the permit writer made the designation that the stormwater discharges, or category of discharges within a geographic area, contributes to a violation of a water quality standard or is a significant contributor of pollutants to waters of the United States. The date must be provided in YYYY-MM-DD format where YYYY is the year, MM is the month, and DD is the day.

No Exposure Certification Approval Date
This is the date on which the No Exposure Certification (NEC) was authorized by the NPDES permitting authority. Submission of a No Exposure Certification means that the facility does not require NPDES permit authorization for its stormwater discharges due to the existence of a condition of "no exposure." A condition of no exposure exists at an industrial facility when all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt, and/or runoff. This date would be provided by the permitting authority. The date must be provided in YYYY-MM-DD format where YYYY is the year, MM is the month, and DD is the day.

Low Erosivity Waiver Approval Date
 The NPDES Stormwater Phase II Rule allows NPDES permitting authorities to accept "low erosivity waivers" (LEWs) for small construction sites. The waiver process exempts small construction sites (disturbing under five acres) from NPDES permitting requirements when the rainfall erosivity factor is less than five during the period of construction activity. This is the date when the permitting authority granted such waiver, based on information from the entity requesting the waiver; this date would be provided by the permitting authority. The date must be provided in YYYY-MM-DD format, where YYYY is the year, MM is the month, and DD is the day.

Notes:
(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 Annual Report [40 CFR 403.12(i)]. Additionally, the NPDES program authority can decide whether to allow NPDES regulated entities to override these pre-populated data.  
(2) The data elements in this table conform to EPA's policy regarding the application requirements for renewal or reissuance of NPDES permits for discharges from municipal separate storm sewer systems (see 61 FR 41698; 6 August 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.
