EPA Updates- All EPA applications below have been updated. As of February 1, 2020, please discard any previous versions and use the updated forms below. Tips for filling out the new application forms can be found here. If you completed an application prior to February 1, 2020, please complete this form and attach it as an addendum to your application.

Chemical Addendum Form- As required by Session Law 2018-5, Senate Bill 99, Section 13.1(r), every applicant shall now submit documentation of any additional pollutants for which there are certified methods with the permit application if their discharge is anticipated. The list of pollutants may be found in 40 CFR Part 136, which is incorporated by reference. If there are additional pollutants with certified methods to be reported, please submit the Chemical Addendum to NPDES Application table with your application and, if applicable, list the selected certified analytical method used. If there are no additional pollutants to report, this form is not required to be included with your application.  This requirement applies to all NPDES facilities.   The Chemical Addendum to NPDES Application will be required for any type of facility with an NPDES permit, depending on whether those types of pollutants are found in your wastewater.  Please be sure to include all information pertaining to Fluorinated Chemicals (e.g., PFAS, et al) and 1,4-Dioxane and specify if these groups are believed present or believed absent.

Chemical Addendum to NPDES Application

Applying for a NEW permit or expansion?

All new and expanding facilities MUST submit an Engineering Alternatives Analysis (EAA) with any required application(s). All new and expanding facilities must pay an application fee according to whether they are major or minor facilities.  The NPDES Fees page lists all applicable permit fees.  Please make checks payable to NCDEQ, and send in the permit fee along with the permit application.  

Guidance on whether your facility is considered a Major Facility?  The EPA uses a Ratings Sheet to help facilities to determine if they will be considered a Major.  If you are not sure whether your facility is a major or minor, please contact the NPDES Permitting Units

  • Major Municipal: Any permit with a permitted flow > 1.0 MGD, a Publicly Owned Treatment Works (POTW) that administers a POTW pretreatment program, or a publicly-owned industrial waste treatment works that have a high toxic pollutant potential (see EPA Ratings Sheet).
  • Major Non-Municipal: Any permit with a score of 80 or higher on the EPA Ratings Sheet.

Renewing your existing permit?

Federal and State regulations require that permit renewal applications be submitted at least 180 days prior to the expiration of the current permit.
