National Pollutant Discharge Elimination System (NPDES)

NPDES Applications and Forms

Applications

The EPA regulations at 40 CFR 122.21 establish permit application requirements for applicants seeking coverage under individual permits. In accordance with these regulations, EPA has developed eight individual permit application forms that correspond to different categories of dischargers subject to permitting.

On February 12, 2019, EPA finalized revisions to the application requirements at 40 CFR 122.21 in the final NPDES Applications and Program Updates Rule. The final rule becomes effective on June 12, 2019. On and after this date, applicants for EPA-issued NPDES permits will be required to meet the new application requirements. EPA has updated each of the eight NPDES application forms to conform to the final rule and improve clarity and usability. See below to determine the appropriate form(s) to submit.

States that are authorized to administer the NPDES program might require use of EPA’s application forms or might have developed their own state-specific application forms. In either case, the final NPDES Applications and Program Updates Rule provides states up to one year to make conforming programmatic and regulatory changes, and up to two years if statutory changes are needed.

Note: For the best results, use Adobe Acrobat Reader DC to open these files (see EPA’s About PDF page to learn more). Even though these publications are PDF files, these documents allow you to type directly onto the form and save the PDFs with the form fields populated. You should enter your facility information on the form, print it, sign it, and mail the form to the address stated in the instructions.

Forms

Construction General Permit (CGP) Corrective Action Report Form (October 15, 2012) -- The corrective action report form is designed to assist operators in preparing corrective action reports that meet the minimum reporting requirements in Part 5.4 of the CGP.

CGP Inspection Report Templates (October 16, 2012) -- The inspection report template is designed to assist operators in preparing inspection reports that meet the minimum reporting requirements in Part 4.1.7 of the CGP.

This function may save time for those users who have numerous vessels and who already have much of the data needed gathered in existing databases. 

Low Erosivity Waiver Certification for Stormwater Discharges Associated with Construction Activity (March 19, 2012) -- Small construction sites can apply for a waiver from the stormwater permit requirements if the construction site has a low predicted rainfall potential where the rainfall erosivity factor (R Factor) is less than five during the period of construction activity. The rainfall erosivity factor waiver uses this factor to determine whether the potential for polluted discharge is low enough to justify a waiver from permit requirements. This waiver is time sensitive and is dependent on when during the year a construction activity takes place, how long it lasts, and the expected rainfall and intensity during that time.
