Septage business license requirements

All septage businesses in the State of Wisconsin that service and/or dispose of septage (septic tanks, holding tanks, sanitary grease interceptors, portable restrooms, privies, etc.) shall be licensed pursuant to ch. NR 113, Wis. Adm. Code. Each vehicle used for servicing and transport of septage shall be inspected and properly registered pursuant to s. NR 113.06, Wis. Adm. Code. Every business shall comply with the septage disposal requirements specified under s. NR 113.07, Wis. Adm. Code.

Each septage business must designate an operator-in-charge (OIC). All individuals servicing septage shall be properly certified under the following designations: operator-in-training (OIT), certified septage vehicle operator, and/or master operator pursuant to ch. NR 114, Wis. Adm. Code. A certification exemption is allowed for portable restroom servicing assistants (PRSAs). Note: PRSAs must work under the direction of the OIC and are limited to only servicing portable restrooms and cannot landspread septage.

Septage businesses must comply with the following Wisconsin Administrative Codes:

For more information on septage operator requirements, please refer to the Septage Operator webpage.

United States Environmental Protection Agency (US EPA) Regulation. The US EPA also regulates the land application of domestic septage through 40 CFR 503. Nearly all of the federal requirements are included in ch. NR 113, Wis. Adm. Code, making compliance easier for Wisconsin septage businesses. Primarily these include requirements such as pathogen control, vector attraction reduction, and nitrogen application limitations. Even though 40 CFR 503 regulates septage as a sewage sludge, septage is afforded many exemptions primarily for disposal. However, septage servicing and disposal require extensive daily logs, and land application activities require certified statements declaring disposal meets state and federal requirements.

Septage business lookup

The Environmental Licensing and Certification (ELC) database is a tool that can be used to search and identify active (licensed) septage businesses either by business name or business license number.

Septage Non-Commercial Operator Lookup

A farmer who disposes of septage on land owned or leased by a farmer may be exempt from ch. NR 113, Wis. Adm Code licensing requirements provided certain conditions are met (reference: sub. NR 113.05(4), Wis. Adm. Code, and s. 281.48(3)(d), Wis. Stats). Subsection NR 113.03(17), Wis. Adm. Code defines a farmer as a "person who owns or leases a contiguous parcel of land of 40 acres or more that the person is using for agricultural purposes." This web link contains a spreadsheet of approved non-commercial septage operators.

Portable Restroom Vehicle Exemptions

Chapter NR 113, Wis. Adm. Code (register 2021) includes several exemptions for vehicles that solely service portable restroom waste. These exemptions are described in the Portable Restroom Businesses section. There are additional daily logbook and invoice record system exemptions for vehicles that solely service portable restroom waste. See the Portable Restroom Businesses section below for additional details.

Department Inspection Authority for Septage Vehicles

Any business engaged in servicing shall allow the vehicles and equipment used for septage servicing to be inspected upon department request. This inspection may be scheduled at any reasonable time and place, as designated by the department. Reference: sub. NR 113.06(1), Wis. Adm. Code.

Septage Business Vehicle Inspection (New Vehicle Registration)

Septage businesses must register all vehicles used for septage servicing with the department.

A vehicle inspection report must be completed for each vehicle the owner or operator intends to utilize under the proposed septage business license. This inspection demonstrates that the vehicle complies with s. NR 113.06, Wis. Adm. Code requirements. The applicant must complete the Wisconsin Septage Servicing Licensee Vehicle Inspection Report (form 3400-019 AKA 019 form) and include photographs of the vehicle. To efficiently process the vehicle inspection report, the department recommends that a certified master operator complete the vehicle inspection report to ensure the application is complete.

IMPORTANT: If the vehicle meets ch. NR 113, Wis. Adm. Code requirements, the vehicle will be issued a business license sticker. This sticker must be properly displayed on the vehicle per subd. NR 113.06(2)(m)1., Wis. Adm. Code.

Septage Vehicle Utilized by Multiple Businesses

It is common for septage businesses to share one or more septage vehicles. Each business that uses a vehicle that is used by more than one septage business, whether under a single owner or separate owners, shall register the vehicle under each business's license and each business license number shall be displayed on the vehicle. Reference: subd. par. NR 113.06(2)(m)2m. Wis. Adm. Code.

Previously Owned Septage Vehicles

It is common for septage business to purchase vehicles from other Wisconsin licensed septage businesses. In these instances, the vehicle must be inspected and registered under the current septage business license.

IMPORTANT: The department recommends that the former septage business remove the business sticker and license number prior to selling the vehicle. A new business sticker will be issued by the department after review of the vehicle inspection report. The original owner should also remove the business license number (number lettered on at least one side of the vehicle).

Renting a Septage Vehicle

A septage vehicle may be rented out to a septage business as long as it is inspected and registered by the septage business. The registration process is similar to the new vehicle registration (see the Septage Business Vehicle Inspection (New Vehicle Registration) section above). The business license number must be on at least one side of the vehicle.

Replacement Stickers

If by unique circumstances, an approved septage vehicle needs a replacement sticker for the same licensing period (i.e., a sticker of the same color and expiration date), then the business may request a new sticker via email or mail.

The business should provide a written statement (letter or email) detailing what happened to the current sticker and which vehicle (year, model, license plate number) needs a replacement sticker. In addition, this notification must include an updated 3400-019 form (AKA 019 form). In the comments section of the 019 form please identify the need for a replacement sticker. Note: The 019 form requires photographs of the vehicle.

  • Evidence of visible cracks or rusting that indicate potential future problems; and
  • Disappearance of volumes of septage with the septage storage facility.

IMPORTANT: Maintenance inspections shall be conducted and recorded monthly (reference; subd. NR 113.12(6)(c)2., Wis. Adm. Code).

Transfer Ownership of Previously Approved Septage Storage Facilities

A septage only storage facility for which the department has issued written approval may continue in operation after the transfer of ownership and upon the new owner of the storage facility completing all of the requirements specified under par. NR 113.12(3)(b), Wis. Adm. Code.

Storage Abandonment

The abandonment of any septage storage facility must comply with par. NR 113.12(7)(g), Wis. Adm. Code. For these situations, please contact the appropriate DNR Regional Septage Coordinator. For a list of regional septage coordinators, please see the DNR Septage Contacts section below.

Spill Plans

Septage businesses are required to develop a written procedure for spill and accident cleanup per NR 113.06(3)(c)2., Wis. Adm. Code. The spill plan must also address spills from septage storage facilities. For more information on spill plans, please see the Spill Plans and Management Plans section above.

Management Plans

Management plans are a collection of detailed procedures relating to storing, mixing, conveying, and land applying septage pursuant to ch. NR 113, Wis. Adm. Code. The management plan typically serves as a standard operating procedure (SOP) for the permittee's or licensee's employees to reference and implement. This document is also utilized by department staff to ensure that the septage storage facility meets WPDES permit and/or ch. NR 113, Wis. Adm. Code requirements. For more information on management plans, please see the Spill Plans and Management Plans section above.

Septage Land Application

The beneficial use of septage and its recycling to the land as a fertilizer or soil conditioner is encouraged. The department regulates the land application of septage per ch. NR 113, Wis. Adm. Code in order to protect public health from unsanitary and unhealthful practices and conditions as well as protect surface waters and groundwaters of the state from contamination by septage. Reference: ss. NR 113.01 and 113.07, Wis. Adm. Code.

Land Application Site Request Submittal

A septage business shall only apply septage to land application sites that meet the requirements of ch. NR 113, Wis. Adm. Code (reference: sub. NR 113.11(1), Wis. Adm. Code). Each business disposing of septage to a land application site shall, at least 7 days prior to using a land application site, submit a site request package to the department.

The permittee or licensed septage business must submit a complete Land Application Site Request (form 3400-053 AKA 53 form) with accompanying documents.

It is recommended that the site request package be scanned and submitted electronically via email to the appropriate DNR Regional Septage Coordinator. For a list of regional septage coordinators, please see the DNR Septage Contacts section below.

IMPORTANT: Incomplete site request packages may be rejected and returned. Applications submitted on modified or altered 53 forms will not be processed.

Department Review of Land Application Site Request

The department's review process considers several factors, including but not limited to:

  • Landspreading method (surface application, injection, incorporation, etc.),
  • Proximity to houses and wells, streams, wetlands, drainageways,
  • Ability of the soil to hold and treat pollutants (permeability and available water holding capacity),
  • Depth to restrictive layers (bedrock and groundwater),
  • Slope and soil erodibility,
  • Other relevant information necessary to protect public health and the environment.

Landspreading sites meeting ch. NR 113, Wis. Adm. Code requirements are issued a Site Approval and Discharge Limits form (form 3400-122 AKA 122 form) and DNR approval maps.

Land Application Site Limitations

Any person who land applies septage shall comply with the minimum separate distances and soil restrictions specified under s. NR 113.07, Wis. Adm. Code.

The maximum weekly hydraulic loading rate (non-winter conditions) shall be limited by soil characteristics and application method. The maximum weekly hydraulic rate is limited 13,000 gallons per acre per week except that injection and incorporation on sites of 6 percent slope or less may be increased per sub. NR 113.09(5), Wis. Adm. Code.

Site Information Required in Land Application Vehicles

When disposing at a land application site, all of the following site related information shall be kept in the vehicle cab pursuant to par. NR 113.06(3)(g), Wis. Adm. Code:

  • A copy of the site request and related submittal information specified under sub. NR 113.11(1), Wis. Adm. Code;
  • A copy of the site approval issued by the department (form 3400-122 AKA 122 form); and
  • A copy of site approval maps issued by the department under sub. NR 113.11(1), Wis. Adm. Code.
Pathogen Control

Pathogen control is required by both 40 CFR 503 and ch. NR 113, Wis. Adm. Code. Pathogen control attempts to reduce pathogen densities in the septage. Proper liming practices and environmental influences such as sunlight and cold temperatures can limit the density of pathogens. Lime treatment includes raising the septage mixture to a temperature corrected pH of 12.0 SU at a temperature of 25 ºC and maintaining a pH of 12.0 SU for no less than 30 minutes.

Additional Site Restrictions. Septage businesses shall comply with the additional site restrictions (food crop, livestock grazing, turf, and public access) specified under par. NR 113.07(3)(d), Wis. Adm. Code.

pH Measurements. Septage businesses may use narrow range pH paper (example: 10.1 to 13.0 SU) to measure pH. To achieve accurate pH monitoring results, businesses should use 3 lots of narrow range pH paper or strips with 3 distinct log numbers.

Septage businesses may also use temperature correcting pH meters, provided these meters are routinely calibrated. The department has created a template Septage: Weekly pH Meter Calibration Log (form 3400-229 AKA 229 form).

Vector Attraction Reduction

There are three different methods of vector attraction reduction (VAR) allowed for septage (per subd. NR 113.07(3)(e)1., 2., and 3., Wis. Adm. Code). Two methods are barrier methods and include incorporation and injection (as defined under ss. NR 113.03(28) and (30), Wis. Adm. Code). One method requires further treatment of septage (treatment with alkali addition).

Incorporation. Septage must be incorporated into the soil to a depth of at least 4 inches within 6 hours after application to or placement on the land per sub. NR 113.03(28) and subd. NR 113.07(3)(e)2., Wis. Adm. Code. Date and time of incorporation must be included on the daily logbook and invoice record systems.

Injection. Septage must be injected (subsurface placement of septage) to a depth of 4 to 12 inches per sub. NR 113.03(30), Wis. Adm. Code.

Treatment with Alkali Addition (pH Measurements). The single VAR treatment includes lime or alkaline treatment to a temperature corrected pH of 12.0 SU at a temperature of 25ºC and maintained at a pH of 12.0 SU or no less than 30 minutes.

Septage businesses may use narrow range pH paper (example: 10.1 to 13.0 SU) to measure pH. To achieve accurate pH monitoring results, businesses should use 3 lots of narrow range pH paper or strips with 3 distinct log numbers. Septage businesses may also use temperature correcting pH meters, provided these meters are routinely calibrated. The department has created a template Septage: Weekly pH Meter Calibration Log (form 3400-229 AKA 229 form).

Nitrogen Application Rate

Septage may only be applied to agricultural lands and may not be applied at rates that will supply available nitrogen at amounts greater than the agronomic need for the crop (per par. NR 113.09(1)(b), Wis. Adm. Code).

Under the federal nitrogen hydraulic formula, approximately 2.5 pounds of nitrogen is available in 1,000 gallons of septage. Septage businesses may use the below formula to calculate the annual agronomic rate (reference: sub. NR 113.09(4), Wis. Adm. Code):

Annual Agronomic Rate (gallons/acre/year) = Pounds Nitrogen (Required Expect Crop)
  0.0026

Other Sources of Nitrogen. Other sources of nitrogen, including manure and commercial fertilizer, must be tracked and reported on the Annual Land Application Report (from 3400-055 for 55 form).

Hydraulic Application Rates (Weekly & Yearly)

Weekly Hydraulic Application Rate. The maximum weekly hydraulic rate of septage application shall be limited by soil characteristics and application method. The maximum weekly hydraulic rate is limited to 13,000 gallons/acre/week (reference: NR 113.09(5), Wis. Adm. Code).

This weekly application rate may be increased if injection or incorporation is utilized on slopes of 6% or less. Alternative weekly application rates are based on the predominant soil map units present on the field:

  • Fields with predominantly sandy loam, loam, and silt loam map units may be increased with department approval to 27,000 gallons/acre/week.
  • Fields with predominantly clay loam map units may be increased with department approval to 20,000 gallons/acre/week.

IMPORTANT: Department approval is necessary for alternative hydraulic application rate limits. See sub. NR 113.09(5), Wis. Adm. Code for more details. Typically, the department requires a septage business to submit a management plan. See the Spill Plans and Management Plans section above for more details.

Yearly Hydraulic Application Rate (Low Use Fields). The yearly hydraulic application rate for low use fields depends on the type of septage land applied.

  • Yearly application for sanitary grease is 12,900 gallons/acre/year.
  • Yearly application rate for septic tank, holding tank, and grease interceptor waste is 39,000 gallons/acre/crop year.

Note: See Table 4 under s. NR 113.09, Wis. Adm. Code for more details.

Ponding, Runoff, And Litter

Land application vehicles shall be moving forward at all times while septage is being uniformly spread. Ponding of septage is prohibited per subd. NR 113.07(3)(b)6., Wis. Adm. Code. "Ponding" means the presence of free liquid over an area of 4 square feet or more, visible 2 hours after application of the septage. An example of a 4 square foot area would be an area 4 feet by 1 foot (reference: sub. NR 113.03(40), Wis. Adm. Code).

Septage shall be landspread in a manner to prevent surface runoff per subd. NR 113.07(3)(b)5., Wis. Adm. Code. Septage may not be landspread on saturated soils during rainfall events or in areas of ponded water.

All landspreading fields shall be left in a litter free condition. "Litter free" means the absence of nonbiodegradable material such as plastics or glass of 2 inches or greater in length on the soil surface (reference: sub. NR 113.03(33), Wis. Adm. Code).

High Use Fields

A "high use field" is approved by the department to receive more than 39,000 gallons per acre of septage per crop year and the volume applied is limited to the crop nutrient requirements (reference: sub. NR 113.03(24), Wis. Adm. Code).

An applicant must submit a morphological soil evaluation pursuant to NR 113.08(1)(b), Wis. Adm. Code. Morphological soil evaluation shall be conducted by a soil scientist per sub. NR 113.03(64m), Wis. Adm. Code

Once approved, the volume of septage landspread on a high use field may not exceed the nitrogen need of the crop to be grown (reference: sub. NR 113.09(2), Wis. Adm. Code).

Portable Restroom Businesses

This tab covers information specific to businesses that solely service portable restrooms. Portables restrooms are defined as fixtures, incorporating holding tank facilities, designed to directly receive human excrement. Portable restrooms are self−contained units, may be designed for one or more person's use at a given time and are readily transportable (reference sub. NR 113.03(41), Wis. Adm. Code.

Portable Restoom Servicing Assistants (PRSAs)

Portable restroom servicing assistants or PRSAs are individuals who service portable restrooms under the supervision of an operator–in–charge (reference subd. NR 114.153(8), Wis. Adm. Code).

A PRSA may service portable restrooms, including the maintenance of portable restrooms and the transportation of the restrooms and the septage from them without being a certified operator (reference: sub. NR 114.16(3), Wis. Adm. Code). However, a PRSA may not land apply septage removed from portable restrooms.

A PRSA is considered to be working under the certificate of the designated operator–in–charge (or OIC). The OIC is responsible for their actions.

Portable Restroom Vehicle Exemptions

Chapter NR 113, Wis. Adm. Code was revised and finalized in September 2021. The revised ch. NR 113, Wis. Adm. Code includes several exemptions for vehicles that solely service portable restroom waste. These exemptions are described below.

  • Shutoff Valves for Suction Hoses. Suction hoses used for cleaning portable restrooms may alternatively be provided with two shutoff valves with one located at the tank and the other shutoff valve located on the wand end of the suction hose. The applicant must identify an alternative location and request approval by the department for that alternative location. Reference: par. NR 113.06(2)(k), Wis. Adm. Code.
  • Alternative Sticker Location. If the placement of the sticker on the rear of the vehicle servicing tank prevents the sticker from being visible when transporting portable restrooms, then the business sticker may be applied to an alternative location on the vehicle approved by the department. Reference: subd. NR 113.06(2)(m)1., Wis. Adm. Code.
  • Capacity (Gallon) Lettering. The capacity lettering requirement does not apply if the capacity of the vehicle tank is 1,000 gallons or less. Reference: subd. NR 113.06(2)(m)3., Wis. Adm. Code.

The attached web link provides example lettering (side) and sticker locations for vehicles that solely service portable restrooms.

Portable Restroom Daily Logbook and Invoice Record Systems Exemptions

Chapter NR 113, Wis. Adm. Code (register 2021) includes several exemptions to daily logbook and invoice record systems for vehicles that solely service portable restroom waste. These exemptions are described below.

  • Daily Log Book and Invoice Record Systems Location. Daily log book and invoice records are not required to be kept inside the vehicle if the records are available at the business location and the records are made available to the department upon request. Reference: subd. par. NR 113.11(3)(c)2.b., Wis. Adm. Code.
  • Gallons Reported on Daily Log Book and Invoice Record Systems. Record the total gallons collected at each service location. Reference: Subd. par. NR 113.11(3)(c)3.d., Wis. Adm. Code.
Septage Business License Application

Per sub. NR 113.05(1), Wis. Adm. Code, every business, before engaging in septage servicing in this state, shall submit an application on forms prepared by the department. The application shall clearly identify the owner and legal entity applying for the septage license. The application shall designate an operator-in-charge (OIC) for the business in accordance with ch. NR 114, Wis. Adm. Code. The OIC shall possess a valid master operator certification for the duration of the business license period. License fees shall accompany each license application. To apply for a new septage business license, the applicant must complete the following items:

Septage Certification - EA/7

Madison WI 53707-7921

IMPORTANT: All of the below steps must be completed prior to servicing septage. Failure to complete these steps prior to septage servicing may result in stepped enforcement pursuant to ss. NR 113.14 and NR 114.245, Wis. Adm. Codes. See the Septage Enforcement section below for additional information.

Designate Operator-in-Charge (OIC)

Each septage business must designate a certified master operator as the operator-in-charge (OIC) for the business per par. NR 113.05(1)(a) and sub. NR 114.18(1), Wis. Adm. Code. The OIC is the individual designated by the owner to be directly responsible for the operation of the septage business. The responsibilities of the OIC include, but are not limited to:

  • Serving as the primary contact for department staff,
  • Maintaining operator records, submitting operator-in-training (OIT) requests, and coordinating operator renewals,
  • Ensuring staff are properly trained to service and dispose of septage,
  • Inspecting and maintaining septage vehicles,
  • Drafting standard operating procedures (SOPs), spill plans and management plans,
  • Reviewing daily log and invoice records systems,
  • Overseeing land application practices, and
  • Certifying Other Methods of Disposal or Distribution Reports and Annual Land Application Reports (forms 3400-052 and 3400-055, respectively).

The licensed septage business may only perform aspects corresponding to the OIC grade designation.

  • A grade T master operator may conduct all aspects of septage servicing except land application of septage (reference par. NR 114.17(1)(a), Wis. Adm. Code).
  • A grade L master operator may conduct all aspects of septage servicing including land application of septage (reference par. NR 114.17(1)(b), Wis. Adm. Code).

IMPORTANT: It is not a requirement that the business owner be a certified operator (or certified master operator). However, the business owner must designate a properly certified OIC (individual with an active master operator license grade T or grade L before a septage business license is issued. For more information on septage master operator requirements, please refer to the Septage Operator webpage.

Complete Form 3400-020 (Septage Servicing New Business Application)

The business must submit a complete Septage Servicing New Business License Application (form 3400-020 AKA 020 form). This step must be completed before finalizing vehicle inspection reports (see below for more details).

IMPORTANT: Septage business applications are typically reviewed by the Septage Certification Program Coordinator. In some instances, an application may also be reviewed by the Regional Septage Coordinator. Septage business applications may take up to 30 days to process.

Complete Form 9400-054 (Social Security Number/Fein Collection Request)

The business must submit a complete Social Security Number/Federal Employment Identification Number (FEIN) Collection Request (form 9400-568). The purpose of collecting a FEIN number is to determine whether the license applicant is delinquent in court-ordered child or family support payments or delinquent in paying Wisconsin taxes under ss 49.857 and 73.0301, Wis. Stats (reference s. NR 114.195, Wis. Adm. Code).

Application Fees

The applicant must pay the appropriate application fees based on Wisconsin residency and number of intended septage servicing vehicles. Current fees are:

  • $50 per Wisconsin vehicle,
  • $100 per out-of-Wisconsin (nonresident) vehicle, and
  • $100 groundwater fee for both Wisconsin resident and nonresident businesses.

Please include the appropriate fees (check made payable to the Wisconsin Department of Natural Resources) when mailing this application to the department.

Complete Vehicle Inspection Report(s)

A vehicle inspection must be completed for each vehicle the owner or operator intends to utilize under the proposed septage business license. This inspection demonstrates that the vehicle complies with s. NR 113.06, Wis. Adm. Code.

The applicant must complete the Wisconsin Septage Servicing Licensee Vehicle Inspection Report (form 3400-019 AKA 019 form) and include photographs of the vehicle as specified on the 019 form. To efficiently process the vehicle inspection report, the department recommends that a certified master operator complete the vehicle inspection report to ensure the application is complete.

After receipt of the above information, the department will email the septage business applicant the business license number. This number must be displayed on at least one side of the vehicle per subd. NR 113.06(2)(m)2., Wis. Adm. Code. Once the vehicle lettering has been updated, the applicant must email photographs to the DNR Septage Certification Coordinator. This step is necessary to complete business registration.

IMPORTANT: If the vehicle meets ch. NR 113, Wis. Adm. Code requirements, the vehicle will be issued a business license sticker (usually at time of license issuance). This sticker must be properly displayed on the vehicle per subd. NR 113.06(2)(m)1., Wis. Adm. Code.

Submittal of New Business Application Materials

The applicant must submit paper copies of the above documents to:

Septage Certification - EA/7
Wisconsin Department of Natural Resources
PO Box 7921
Madison WI 53707-7921

IMPORTANT: Completing and submitting the septage business application and appropriate fees are mandatory under s. 281.48, Wis. Stats., and ch. NR 113, Wis. Adm. Code. Incomplete applications will be denied in writing by the department. Failure to complete an application and receive a septage business license prior to septage servicing may result in stepped enforcement pursuant (example: issuance of citations) to ss. NR 113.14 and NR 114.245, Wis. Adm. Codes. See the Septage Enforcement section below for additional information.

License Renewal

Septage business licenses and vehicle stickers are valid for two years and expire on June 30 in every odd-numbered year. Please refer to the Septage Business License Renewal section below to learn more about septage business license renewals.

Septage Business License Renewal

Septage business licenses and vehicle stickers are valid for two years and expire on June 30 in every odd-numbered year. During odd-numbered years, all licensed septage businesses must renew their license. A complete renewal package is due to the Department by June 1.

IMPORTANT: The septage business license and vehicle stickers issued to all registered businesses reflect the date businesses and vehicles expire.

Septage Business Renewal Requirements

In the spring (typically April) of every odd-numbered year, the department mails a business license renewal application to each septage business owner. The renewal application contains the following information:

  • Business license renewal application cover letter, and
  • Septage Business License Renewal Application (form 3400-126 AKA 126 form) Note: This form is generated by Septage Operator Certification, and then mailed to the septage business during the license renewal period (~April of every odd year).

The 126 form requires the business owner to:

  • Verify business contact information (phone number, email address, and/or mailing address);
  • Verify vehicle information (license plate number, year/make/description, and tank capacity). Notes: This list must include all owned, leased, and/or shared vehicles operating under the septage business license. Any new vehicles must be property registered; see the Septage Servicing Vehicles section above for more information;
  • Verify that all annual reports have been submitted and certified to the department within the two previous calendar years; and
  • Provide a list of all operators (including operators-in-training). Note: It is helpful if this list contains each individual's full name, operator certification number, and start date.

Septage business renewal applications (including applicable fees) should be mailed to:

Septage Certification - EA/7
Wisconsin Department of Natural Resources
PO Box 7921
Madison WI 53707-7921

IMPORTANT NOTES: Check or money orders must be made payable to the Wisconsin Department of Natural Resources. An incomplete renewal application will delay processing and renewal of a business's license.

Department Review

In order to renew, a septage business license, a business must meet the following requirements:

  • Pass a business Federal Employment Identification Number (FEIN) or Social Security Number (SSN) check. The DNR shall request a non-delinquency certification from the Departments of Children and Families, Revenue, and Work Force Development under ss. 49.857, 73.0301, and 108.227, Wis. Stats, prior to issuing a license, renewing a license, or allowing a business to designate a master operator as operator-in-charge (OIC). DNR submits a FEIN/SSN check for all septage businesses shortly before license renewal. DNR will coordinate with the appropriate agency if it is identified that a business owner is delinquent on Wisconsin taxes or court-ordered child or family support payments.
  • Submit all required annual reports (Annual Land Application and Other Method of Disposal Reports) over the past two calendar years. The deadline to submit all annual reports is January 31 of each year (reference: sub. NR 113.11(3), Wis. Adm. Code). For more information, refer to the Annual Reporting section.
  • Pay all renewal fees. Renewal feeds include a groundwater fee ($100/business) and vehicle fees ($50/truck for Wisconsin residents and $100/truck for nonresidents). In addition, renewal fees include a $25 late fee if the renewal materials were submitted after June 1.
  • Verify Operator-in-Charge (OIC). The business must have a certified master operator to serve as OIC. For more information on septage master operator requirements, please refer to the Operator-in-Charge (OIC) section above as well as the Septage Operator webpage.

Once a renewal application has been processed and approved, the department renews the business license and mails the appropriate number of vehicle stickers to the business. The business now maintains the license until the next renewal date.

Septage Business Renewal Status Update

Due to the high volume of license renewal applications, the Septage Operator Certification Program recommends that businesses refer to the Septage Business Lookup (located on the main DNR Septage Business webpage) for updates to see if the business has been renewed. The lookup site may be updated several days before receiving vehicle stickers via mail.

Septage Operator Certification Renewals

For more information on septage operator renewals, please refer to the Septage Operator webpage.

Septage Related Forms

This tab contains a list common septage forms. Note: The department is in the process of revising many of these forms to comply with the revised chs. NR 113 and NR 114, Wis. Adm. Code (register September 2021 and April 2022, respectively).

Septage Business License Related Forms
Septage Land Application Related Forms
Septage Storage Related Forms
Septage Template Daily Logbook and Invoice Record Systems

Note: Septage businesses are not required to use the below template daily logbook and invoice record systems. Septage businesses are encouraged to contact their regional septage coordinator to verify records comply with s. NR 113.11, Wis. Adm. Code.

Septage Vehicle Related Forms
Septage Enforcement

Enforcement actions follow the DNR stepped enforcement process. This process begins with the lowest form of enforcement appropriate for the circumstances and may be incrementally elevated to the highest level of enforcement, resulting in litigation in the courts.

Enforcement Approach

Figure 1 shows the steps of enforcement action that may be taken. The level at which an enforcement action begins is case-specific and based on the severity of the noncompliant event. The stepped enforcement approach is a fluid process, and it is not legally required that all enforcement actions follow these steps in sequential order regardless of the current status or step of the process.

The DNR has the option of referral to the Wisconsin Department of Justice (DOJ) or citation authority under ss. 281.48(5s) and 281.98, Wis. Stats., and ss. NR 113.14 and NR 114.245, Wis. Adm. Code. A citation may be issued at any point within the stepped enforcement process. Environmental citations are essentially tickets for specific violation(s) to an individual or business. A conservation warden issues citations to the individual and/or business.

United States Environmental Protection Agency (US EPA) Enforcement. The US EPA also regulates the land application of domestic septage through 40 CFR 503. Nearly all 40 CFR 503 federal requirements are included in ch. NR 113, Wis. Adm. Code. US EPA operates independently of Wisconsin DNR and may investigate complaints and prosecute independently of Wisconsin DNR. Violations are generally subject to larger monetary penalties and may include imprisonment.

Operator Suspension

An automatic suspension of an operator certification results when individuals fail to obtain the required continuing education credits to maintain an active certification. Septage operators are required to obtain three septage compliance credits during the three-year certification period. Master septage operators are required to obtain three septage compliance credits and 15 general septage credits during the three-year certification period. Without the proper continuation hours, the department is unable to renew a certification for an individual and the certification lapses.

For more information on septage master operator requirements, please refer to the Septage Operator webpage.

Business/Operator Revocation and non-Renewal

There are numerous ways a septage business license or an operator certification can be revoked or non-renewed. These ways are identified in: ss. 145.20, 281.17, and 281.48, Wis. Stats. Business licenses can also be revoked pursuant to s. NR 113.05, Wis. Adm. Code. The department may issue citations to the business and/or responsible individual pursuant to subs. NR 114.14(3) and NR 114.24(1), Wis. Adm. Code.

DNR Septage Contacts

It is recommended that septage businesses reach out to the DNR Septage Certification Program Coordinator for questions regarding:

  • septage business license issuance and renewal,
  • operator exams and applications,
  • operator certification and renewal,
  • certified operator continuing education, and
  • vehicle registrations.

It is recommended that septage businesses reach out to their DNR Regional Septage Coordinator for compliance assistance including, but not limited to:

  • daily log and invoice system records review,
  • management plan reviews,
  • septage storage,
  • land application site submittal and approval,
  • land application and disposal standard operating procedures (SOPs),
  • other types of disposals and/or issues with wastewater treatment facilities (WWTFs), and
  • annual reporting.

To provide timely customer service, it is helpful to identify the full septage business name and license number in all correspondence with the department.
