Here are the requirements once construction (and all related land disturbing activity) has been completed:
- The project site owner must remove all temporary erosion control fixtures.
- The entire site must be permanently stabilized.
- The project site owner must submit a notice of termination ( NOT ) letter to IDEM .
- The owner of a site that has been divided into multiple building lots may submit a NOT letter even if all the sites have not yet been developed if:
- The undeveloped area does not exceed 5 total acres, with no contiguous areas of 1 or more acres
- All permanent storm water measures are in place
- All common areas and infrastructure have been completed and stabilized
- A map of all undeveloped lots and the names of their owners is submitted with the NOT letter. If such "early release" is approved by IDEM , the project site owner must notify each owner of undeveloped property and inform them of their storm water pollution prevention responsibilities.
