You may need a PDF reader to view some of the files on this page. See EPA's About PDF page to learn more.

2019 Update for Permittees

The NCCW GP will expire on November 4, 2019.  The General Permit will be administratively continued in accordance with the Administrative Procedures Act and remain in force until EPA either reissues the General Permit or a formal permit decision is made by the EPA Region 1 Director not to re-issue the General Permit, at which time the permittee must seek coverage under an alternative general permit or an individual permit (see Section 7.1 of the NCCWGP).

In order to retain your facility's authorization to discharge NCCW under the administratively continued NCCW GP, a permittee who was granted permit coverage prior to the expiration date of the NCCW GP's expiration date must, prior to December 4, 2019, provide EPA with the information requested in the below documents (Administrative Continuation Request (ACR) information). You may use the template provided or provide the same information submitted on company letterhead. Prior to completing the ACR, please review the previous Notice of Intent (NOI) submitted for coverage under the 2014 NCCW GP (see link to archive below).

PLEASE NOTE Federal regulations require this application to be signed as follows:

  1. For a corporation, by a principal executive officer of at least the level of vice president;
  2. For a partnership or sole proprietorship, by a general partner or the proprietor, respectively, or,
  3. For a municipality, State, Federal or other public facility, by either a principal executive officer or ranking elected official.
