NMPDES NOI Filing Transition — From EPA NeT to NMED eDMR

Current NMR100000 NOIs are filed through EPA's NeT (NPDES eReporting Tool) at cdx.epa.gov. When NMPDES takes effect, NOI filing will transition to NMED's eDMR system. During the transition window, Inspections Plus monitors filing requirements and handles submissions on behalf of clients.

How Inspections Plus Handles Your Filings

NOI Filing: Inspections Plus prepares and submits all NOIs through EPA NeT (current) or NMED eDMR (post-transition) on behalf of clients. We retain confirmation numbers and acknowledgment letters.
NOT Filing: Once final stabilization is achieved (70% perennial vegetative cover), we prepare the Notice of Termination package and file within the required 30-day window.
Transition Monitoring: We monitor the NMED docket, WQCC proceedings, and EPA guidance in real time. Clients receive immediate notification when the NMPDES effective date is established.
Records Retention: All NOI acknowledgments, NOT confirmations, and inspection records are retained for the required 3-year post-NOT period and provided to clients at project closeout.
