Home / Guides / Notice of Termination (NOT)

When can you file a Notice of Termination (NOT)?

A Notice of Termination (NOT) ends your construction stormwater permit coverage. Under EPA's 2022 CGP you may file it only after you finish construction and meet final stabilization with photographs, remove construction materials, temporary controls and pollutants, or after you transfer the site to another covered operator or move to another permit. File within 30 calendar days of meeting a condition, in EPA's NeT system. EPA 2022 CGP Part 8.2, 8.3, 8.4

National guide. The rules cited are from EPA's 2022 Construction General Permit (as modified in 2025), checked October 20, 2026, which applies where EPA is the permitting authority. Most states issue their own permit with different details; check your state before relying on a number.

All construction and support activities are done, and: disturbed areas you controlled that are not under permanent structures meet final stabilization; you took photographs before and after final stabilization, clear, in their original format, dated and described, and submit them with the NOT; construction materials, waste, equipment and vehicles are removed unless kept for long-term use; temporary stormwater controls are removed unless kept for long-term use or biodegradable; and potential pollutants are removed. EPA 2022 CGP Part 8.2.1
Transfer. You transferred control of all your areas to another operator who has filed an NOI and obtained coverage. EPA 2022 CGP Part 8.2.2
Other permit. You obtained coverage under an individual or alternative general permit. EPA 2022 CGP Part 8.2.3
