When can a notice of termination be filed?

A notice of termination (NOT) can be filed after all construction activities are complete and stabilization is verified because this indicates that the site has reached a state that no longer requires the coverage under the stormwater permit. Proper stabilization is essential as it helps to minimize the potential for stormwater pollution by ensuring that the site is adequately vegetated or otherwise treated to prevent erosion and runoff. This requirement aligns with regulatory standards aimed at maintaining water quality and managing stormwater effectively once construction is finished.

In contrast, filing a notice of termination after inspections by environmental agencies or merely halfway through a project does not meet the criteria necessary for termination, as the project must be fully completed and stabilized. Additionally, filing a notice prior to the start of construction is not permissible since there would be no completed activities to warrant a termination of the permit. Therefore, the correct timing for filing an NOT is precisely after all construction is completed, ensuring compliance with the necessary environmental controls.
