Permit and Request Fees

Permit and request fees are cost-recovery fees for administering the Industrial Pretreatment Program. Permit fees are based on permit type. Significant Industrial User (SIU) status, reporting frequency, and annual volume of wastewater. Permit fees are paid annually. The initial Liquid Waste Hauler and Special Discharge permit fee are required at the time of permit application.

Liquid Waste Hauler Permits

Hauler Permit Type Volume (gallon/year) 2021 Permit Fee
Liquid Waste Hauler >1 million $1,750
Liquid Waste Hauler <1 million $1,075
Sewer Cleaning Waste Hauler NA $425

Special Discharge Permit

Permit Category 2021 Permit Fee
Quarterly Reporter $1,750
Contingency/Low Impact $1,075

Special Short-Term Request Fees

Request Type Fee Notes
In Service Area* $150 For non-permitted facilities only; applies to requested volumes greater than 500 gallons; fee invoiced with approval letter
Out of Service Area* $300 For non-permitted facilities only; no minimum volume; fee payment required with request

*Service Area means “Metropolitan Area” as defined in the Waste Discharge Rules. It is the area over which the Metropolitan Council has jurisdiction and includes Anoka, Carver, Dakota (excluding Northfield), Hennepin (excluding Hanover), Ramsey, Scott (excluding New Prague) and Washington counties.

Note: In addition to cost recovery fees above approved discharges are subject to applicable strength, volume, and load charges.

Strength Charge

Strength Charges are assessed by MCES to industrial users and liquid waste haulers based on waste volume, chemical oxygen demand (COD) and/or total suspended solids (TSS) levels exceeding base concentrations, to recover the added costs for treating these high strength wastes. Base concentrations are COD and TSS concentrations of normal residential wastewater.

Formula Strength Charge=[Vx(TSS-250)x(8.34)x(TSS Rate)+Vx(COD-500)x(8.34)x(COD Rate)]
Component Definition
Strength Charge = Strength Charge, in dollars
V = Volume, in million gallons per reporting period
TSS = Total Suspended Solids in mg/L (TSS>250)
    If TSS is less than 250 mg/L, use 250 mg/L
COD = Chemical Oxygen Demand in mg/L (COD>500)
    If COD is less than 500 mg/L, use 500 mg/L
250 = TSS threshold value, in mg/L
500 = COD threshold value, in mg/L
8.34 = Conversion factor, converts mg/L and gallons to pounds
TSS Rate - 2020 = Via onsite connection: $0.260/lb of excess TSS
= Via permitted waste hauler: $0.413/lb of excess TSS
COD Rate - 2020 = Via onsite connection: $0.130/lb of excess COD
= Via permitted waste hauler: $0.2065/lb of excess COD

Production-Based Strength Charge

Microbreweries on General Permit pay a production-based charge using typical COD and TSS concentrations for producing beer. Any microbrewery can instead opt to sample its wastewater and pay the associated strength charge.

Permit Type 2021 Rate
Microbrewery and Brewpub General Permits $0.815 per barrel of beer produced

Load Charges

Load Charges for hauled waste combine a strength charge, facilities, and volume component. The volume component is based on the MCES municipal wastewater rate that connected users pay through their communities.

Load Type 2021 Rates
Domestic Holding Tank $11.29/1,000 gallons
Domestic Septage and Commercial (excluding PTW) $60.24/1,000 gallons
Portable Toilet Waste (PTW) $77.46/1,000 gallons
Industrial Waste* Strength Charge (TSS rate $0.413/excess lb and COD Rate $0.2065/excess lb) + Domestic Holding Tank rate ($11.29/1,000 gallons) + Out-of-Service Area fee for loads generated outside of the metropolitan region* ($15.00/1,000 gallons)
Out-of-Service Area* $75.24/1,000 gallons

*Hauled Industrial Waste and Out-of-Service Area flammable and sand trap waste loads must be approved by the MCES Industrial Waste and Pollution Prevention section prior to discharge and transported to the Metropolitan Liquid Waste Receiving facility located in St. Paul.

Sewer Availability Charge (SAC)

SAC is a charge to customer communities served by the Metropolitan Disposal System for each new connection or increase in capacity demand to the system. All about SAC.

2021 SAC Rate
$2,485 / SAC unit (1 SAC unit- 274 gallons per day)

Industrial Capacity Charge (ICC)

ICC is a fee charged directly to permitted industrial users for discharge volumes exceeding their facility's SAC baseline threshold during a reporting period. Paying ICC does not increase a facility's SAC baseline. Industries have the option of paying SAC in lieu of ICC, which will increase their baseline.

See the ICC Assessment and Payment Options fact sheet for more information.

2021 ICC Rate
$2.18/1,000 gallons discharged over the SAC baseline threshold during a reporting period

Temporary Capacity Charge

Permittees discharging contaminated groundwater via an on-site sanitary sewer connection will be assessed a Temporary Capacity Charge in lieu of SAC.

2021 Rate Notes
$1.25 per 1000 gallons Applies to Special Discharge Permit holders that discharge contaminated groundwater through an on-site sewer connection.

Enforcement Fees

Enforcement fees are cost-recovery fees assessed for response to violations of the MCES Waste Discharge Rules and Industrial Discharge Permit conditions.

Notice of Violation (NOV)

An NOV is a written notification stating that MCES considers a user of the MDS to be in noncompliance with the MCES Waste Discharge Rules or conditions in the Industrial Discharge Permit.

Discharge NOV Fee

The cost recovery fee for a discharge NOV is $200.

Administrative NOV Fee

The cost-recovery fee for an administrative NOV is $150.

Self-Monitoring Report (SMR) Late Fees

Submitting an SMR late delays invoicing for strength charges and critical data collection. Additional administrative late fees are charged that increase with the frequency and duration of a calendar year as follows.

Days Late 1-30 Days 31-60 Days 61-90 Days Subtotal
1st Late Report $150 $150 $150 $450
2nd Late Report $150 $200 $250 $600
3rd Late Report $150 $250 $300 $700
4th Late Report $150 $300 $350 $800

Order to Appear (OTA) Fee

An OTA is a formal order to a specific representative of an industrial user to appear before MCES personnel for purposes of showing cause why MCES should not proceed to modify, suspend, or revoke the industrial user's Industrial Discharge Permit.


The cost recovery fee for an OTA is $350.
