Authorizations to Construct

After an NPDES permit has been issued by the Division of Water Quality, the permittee must obtain an Authorization to Construct from the Division prior to commencement of the construction of modifications or expansion of wastewater treatment facilities.  Authorizations to Construct are required for the following:

  • Construction of new or expanding treatment facilities
  • Any addition, deletion, or modification of equipment or processes at an existing facility which has the potential to affect the treatment process
  • Upgrade or replacement of equipment with that of a different design or capacity that already permitted
  • Installation of piping which has the potential to by-pass any equipment or treatment component

If your project consists solely of installation of new decholorination treatment then you may be eligible to apply for a Fast Track Dechlorination Authorization to Construct.  Please see the Fast Track Guidance for more information.

For projects funded by the Infrastructure Finance Section see Plan and Specification Approval for additional requirements.

If you have any questions about whether your project requires an Authorization to Construct please contact Seth Robertson, PE at (919) 707-9175.
