Approved Alternate Phase 2 Compliance Deadlines
The NPDES eRule allows an authorized NPDES program to submit a request to EPA to establish an alternative compliance Phase 2 deadline for electronic reporting of one or more general permit reports, program reports, and related data elements [see 40 CFR 127.24(e)]. A State may request to establish an alternative compliance deadline of up to three years beyond the currently applicable date but not beyond December 21, 2028. It is the duty of the authorized NPDES program to apply for a new alternative compliance deadline. States must submit a request at least 120 days prior to the applicable compliance deadline in Table 1 to 40 CFR 127.16 or an alternative compliance deadline previously approved by EPA [40 CFR 127.24(e)].
The table lists the approved alternative compliance Phase 2 deadlines.

The NPDES eRule allows EPA to establish an alternative compliance deadline up to three years beyond the currently applicable date, but in no event beyond December 21, 2028 (see 40 CFR 127.24(f)). The memorandum below provides notice that EPA is providing more time to implement electronic reporting for the NPDES general permits and program reports that will use EPA’s electronic reporting tools. This extension does not cover NPDES general permits and program reports that are already using EPA’s electronic reporting tools. The NPDES general permits and program reports not covered by this extension are provided in the NPDES eRule Phase 2 Implementation Dashboard, where the “Application Deployment Status” is set to “Yes.” This extension also does not cover NPDES program data that are collected by individual NPDES permit applications or are generated by the EPA Regions and authorized states (e.g., data related to core NPDES permitting, compliance, and enforcement). See Tables 1 and 2 in Appendix A, 40 CFR part 127, where the “NPDES data group” field is set to “1 - Core NPDES Permitting, Compliance, and Enforcement Data [40 CFR parts 122, 123, 403, 503].” This additional time allows EPA and authorized states to allocate their resources in a manner that will help ease implementation. This alternative compliance deadline balances the need for more time to implement Phase 2 against the goals of the NPDES eRule (see 40 CFR 127.1).
