Apply for or Renew a Wastewater Discharge Permit

The wastewater discharge permit process helps the City maintain water quality by controlling what industrial businesses release into the City water system.[Salem Revised Code Chapter 74]

Apply for a new permit

Any business that wants to discharge industrial wastewater to the City’s water treatment processing must first get a wastewater discharge permit. The initial application must be submitted to Environmental Services 90 days prior to discharge. Once your application is approved, you will be sent an invoice for the initial wastewater permit fee. See Fees below.

Facilities that generate regulated wastewater but do not discharge the wastewater to the City’s system, must apply for a zero wastewater discharge permit.

Renew your wastewater discharge permit

If your existing wastewater discharge permit needs to be renewed, fill out the renewal application and submit to Environmental Services. Permit renewal applications must submitted no less than 90 days prior to the expiration of the user's existing permit. Upon review of the application, Environmental Services will determine the length of the permit renewal and you will be sent an invoice for the wastewater permit renewal fee. See Fees below.

Processing and compliance

Information on processing and compliance with standards is required to satisfy Federal General Pretreatment Regulations 403.12, including submittal of baseline monitoring reports.
