August 13, 2021 is the last day that the ADEM Water Division will accept new submissions for Notices of Intent (NOI) for the NPDES General Permits remaining in eNOI. eNOI will remain available to revise existing submissions until mid-September 2021..

As of November 15, 2021, all Notices of Intent (NOI) for NPDES General Permits should be submitted through ADEM’s new Alabama Environmental Permitting and Compliance System – AEPACS. AEPACS will then be your interface with the Department for all aspects of permitting and compliance. You will be able to apply for coverages under General Permits, renew and manage coverage for General Permits, pay fees, and submit reports and certifications related to your facilities. AEPACS will be phased in throughout the Department in many programs over the next several years, as resources allow.

We appreciate your patience as we move through this transition period.

If you must submit an initial NOI for new coverage under a General NPDES Permit or a modification of existing coverage during the period of August 14-November 15, 2021, you may, for that limited timeframe, submit a hardcopy NOI. Hardcopy NOI’s received after November 15, 2021, will not be accepted.

NOTE: Permittees applying for reissuance of coverage under General NPDES Permits ALG160000 and ALG340000 are not eligible for submitting hard copy submissions. Given the timing of this transition, the Department has notified each permittee that for continued coverage under General NPDES Permit Number Nos. ALG160000 and ALG340000, the Department will consider any NOI submitted on or before December 14, 2021, as timely for continued coverage.
