INTRODUCTION

This appendix contains information on the National Pollutant Discharge Elimination System (NPDES) permits for construction site storm water discharges in the state of Illinois. It contains a general overview of the program, the NPDES Permit No. ILR10 Construction Site Activities, the Notice of Intent (NOI) form, the Incidence of Non-Compliance (ION) form, and the Notice of Termination (NOT) form.

These materials have been provided by the Illinois Environmental Protection Agency (EPA) who is responsible for administering the program in Illinois. Questions about the program should be directed to the Illinois EPA-Division of Water Pollution Control Permits Section, P.O. Box 19276, Springfield, IL 62794-9276, phone 217-782-0610.

The NPDES Permit No. ILR10, and the NOI, ION, and NOT forms are in a read-only format.  They are available in Adobe Acrobat pdf format only.

NATIONAL POLLUTION DISCHARGE ELIMINATION SYSTEM (NPDES)
PERMITS FOR CONSTRUCTION SITE STORMWATER DISCHARGE

General

Under the provisions of the Clean Water Act Amendments of 1987 and the federal regulations at 40 CFR Part 122.26(b)(14)(x), operators of construction sites are required to have NPDES permits for the discharge of storm water except "…operations that result in the disturbance of less than five acres of total land area which are not part of a larger common plan of development or sale." The following are the definitions that the United States Environmental Protection Agency (USEPA) uses for "operators" and "part of a larger common plan of development or sale".

The Illinois General Permit for Construction Site Storm Water Discharges

The Illinois Environmental Protection Agency has issued an NPDES general permit for discharges from construction site activities. The major features of the Illinois permit are the following:

The Phase II Storm Water Program

On December 8, 1999 USEPA published final regulations for Phase II of the NPDES storm water program. The new regulations reduce the size of sites that are required to have permits from five acres or more to one acre or more. The larger common plan of development or sale requirement remains unchanged, so a construction project that is less than one acre would need a permit if it was part of a larger common plan of development or sale that would ultimately result in the disturbance of one acre or more. The one acre requirement is effective as of March 10, 2003, and operators of construction sites that result in a total land disturbance of one acre or more must apply for permit coverage on or before March 10, 2003.

How to Obtain Coverage Under the Permit

To obtain coverage under the permit the operator must complete the one-page Notice of Intent (NOI) form, sign it, and send the original signed copy to the Illinois EPA. Unless notified by the Agency to the contrary, coverage under the permit is automatic, and operators are authorized to discharge storm water from construction sites under the terms and conditions of the permit either:

or

The Agency will confirm the permit coverage and the project’s permit number by letter approximately one week after the automatic coverage takes effect.

Termination of Coverage Under the Permit

After the land disturbing activities are complete and the site has been finally stabilized the operator should terminate his coverage under the permit by completing a Notice of Termination form and submitting it to the Agency. USEPA considers that a site has been finally stabilized when all land disturbing activities are complete and a uniform perennial vegetative cover with a density of 70 percent of the cover for unpaved areas and areas not covered by permanent structures has been established or equivalent permanent stabilization measures have been used.
