Wastewater Discharge Permitting Technical Review Process

EPD has established a technical design review process in addition to the permitting process for new or expanding facilities. A permitted facility that plans to modify a treatment component, furthermore, may be required to submit certain documentation to EPD.

Before submitting any documents or requesting a new or modified individual NPDES or LAS permit, facilities are encouraged to review the applicable process outlines and step descriptions as follows:

• Domestic Wastewater Facility Process
• Industrial Wastewater Facility Process
• Review Step Details

Please be advised that the Wastewater Regulatory Program may require additional information not listed below as necessary for individual projects. More specific information on the following submittals and general design guidance may be found here.

Domestic Wastewater Facilities

The following provides a framework for the technical review process for a new, expanding, or upgrading domestic wastewater facility. Facilities should note that some steps may only apply to either a POTW or a PID specifically. EPD may also require additional information not listed as necessary for individual projects.   New facilities must submit the " Wastewater Regulatory Program New Facility Form " to the Wastewater Regulatory Program prior to submitting a permit application.

Please be advised that each step should be completed and approved as required before a subsequent step may be approved by EPD.

Domestic wastewater facilities that wish to extend their sewer lines and/or install a pump station, but will remain under their current permitted flow limit, should submit Plans and Specifications to EPD along with the Sewer Extension Form . EPD will then make a determination if a review of the certified P&Ss is required.For some of the steps listed here, basic descriptions have been provided. Facilities may also review our guidance documents for more detailed information here.

Please note that above process is required for facilities seeking a new or modified individual permit. Requirements for a general permit will be specified in the instructions for that permit. Please view our general permits for more information.
