Discharge Guidelines

Prior to discharging industrial waste to the sewer, all dischargers who generate and dispose of industrial wastewater should contact the Industrial Pretreatment Program. Potential dischargers will be sent a permit application package if a written discharge approval is necessary. You may also request that a permit application package be mailed to you by calling the Industrial Pretreatment Program at 208-234-6256, or go to our Permit Applications tab

Permit Timelines

The time it takes to obtain a permit depends upon the type and amount of wastewater a company discharges to the sewer. There are 2 types of standards and limitations (Local Pretreatment Limits and Federal Pretreatment Limits) that apply to a company's discharge. Visit our Federal Pretreatment Limits page for a list of federally regulated industries. Some approvals for very low-volume or one-time discharges can be made verbally or by letter.

For federally regulated discharges you must apply for a permit 90 days prior to discharge. For Pocatello regulated discharges have the following requirements:
  • Flows greater than 25,000 gallons per day shall submit a completed application 90 days prior to commencement of operation
  • Flows less than 25,000 gallons per day shall submit a completed application 30 days prior to commencement of operation

Types of Approvals

The Industrial Waste Program issues several types of discharge approvals. These include
  • Discharge authorizations
  • Discharge letters
  • Permits
  • Verbal approvals
The type of approval is determined by the volume discharged, the nature of the business, the characteristics of the wastewater, and the potential risk to the treatment plant.

Industrial Waste Fees

There is no fee associated with the issuance and renewal of Waste Discharge Permits, Discharge Authorizations, and Letters of Authorization.

Surcharge Program

Pocatello has surcharges for Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), Fats, Oils & Grease (FOG), Total Phosphorus, Total Kjeldahl Nitrogen, and volume of flow. Facilities are charged fees to pay for the costs of treating their high-strength wastewater. The surcharge or high-strength fee is based on the volume of water discharged and the amount of TSS, BOD, FOG, Total Phosphorus, and/or Total Kjeldahl Nitrogen in the wastewater.
