Septage servicing operator certification

Alert icon

2024 In-Person Paper Exam: 

The Operator Certification program will be hosting in-person exam sessions in 2024. Exams will be held throughout the state roughly two days each month beginning in March 2024. Once dates and locations are finalized, more information about the in-person paper exams and updated exam application forms can be found on the Operator Certification Exams Page under the DNR Applications tab within the DNR In-Person Paper Exam Application Forms subsection.

All septage businesses in the State of Wisconsin must designate a master operator to serve as operator-in-charge (OIC). The OIC is directly responsible for the operation of the septage servicing business (reference: sub. NR 114.153(5), Wis. Adm. Code).

All individuals servicing septage shall be properly certified under the following designations: operator-in-training (OIT), certified septage operator and/or master operator pursuant to ch. NR 114, Wis. Adm. Code. An operator 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 operators must comply with the following Wisconsin Administrative Codes:

Program Schedule

To assist operators with preparation and timing for certification exams, certification renewals and septage business license renewals, refer to the Septage Operator Certification Program Schedule.

Septage Operator Certification Renewal

All septage operator and master operator certifications expire 3 years from the date of issuance (reference sub. NR 114.22(1), Wis. Adm. Code). For example, if a septage operator was certified in March 2023, the operator certification would expire March 1, 2026.

IMPORTANT: Operators are responsible for keeping track of their certification expiration date, accumulating the required number of continuing education credits and ensuring fees are paid.

Renewal Information

A septage operator or master operator who desires to renew their certification shall submit:

  • Evidence of having met the continuing education requirements in s. NR 114.23, Wis. Adm. Code for approved training courses (see Septage Certified Operator Continuing Education section), and
  • Applicable renewal fee (see Septage Operator Fee Overview section).

The above information can be emailed to DNROpCertSeptage@Wisconsin.gov or mailed to the address below:

Wisconsin Department of Natural Resources
Septage Certification - EA/7
101. S. Webster St.
PO Box 7921
Madison WI 53707-7921

Expired Operator Certification

IMPORTANT: Operators shall not continue to service septage with an expired certification (reference par. NR 114.22(3)(d), Wis. Adm. Code). Continuing to service septage with an expired certification may result in stepped enforcement from the department (see Septage Enforcement section).

An individual whose operator or master operator certification has expired may, within one year of the expiration date, be reinstated by paying the renewal fee, the late penalty fee and fulfilling the continuing education requirements (reference: par. NR 114.22(3)(a), Wis. Adm. Code). See Septage Operator Fee Overview section for more details.

If an individual's master operator certification is expired less than 5 years but more than 1 year, the person may use previous septage operator work experience from the 2 years prior to the expiration date to fulfill the 1600-hour master operator experience requirement. The department may require the person to participate in the master operator training class and pass the appropriate master operator examinations to fulfill the master operator requirements (reference par. NR 114.23(b), Wis. Adm. Code).

Operators and master operators may not renew a certification by taking the certification examinations in lieu of obtaining continuing education credits unless the certification has been expired for at least one year (reference par. NR 114.23(c), Wis. Adm. Code).

Operator-In-Charge (OIC) Expired Certification

If an operator-in-charge (OIC) lets their master operator certification expire, the business must assign another master operator as OIC. The department recommends that each septage business have at least two master operators on staff:

  • One master operator to serve as the OIC, and
  • One master operator to serve as a backup OIC.

IMPORTANT: If the OIC's certification expires and there is no backup master operator (to be designated as OIC), then the business must cease servicing septage (reference par. NR 113.04(1)(b), Wis. Adm. Code). Continuing to service septage without a certified OIC may result in stepped enforcement from the department (see Septage Enforcement section).

Renewal Reminder

Typically, a renewal reminder letter is mailed to the operator approximately 6 weeks prior to expiration of the individual's certification. An example reminder letter is available for review.

Note: Renewal reminder letters are strictly a courtesy and are mailed to last known address saved in the Operator Environmental Licensing and Certification (ELC) database. Operators are responsible for keeping track of their certification expiration date, accumulating the required number of continuing education credits and ensuring payment of applicable fees.

Tracking Operator Certification

The Environmental Licensing and Certification (ELC) database is a tool that can be used to search and identify certified septage operators by name or certification number.

Rejection Of Certification Renewal

The department may reject incomplete or insufficient renewal applications. Applicants will be notified of this rejection in writing.

IMPORTANT: The department shall not renew a certificate for septage servicing for a period of 2 years if an operator has accumulated 6 or more violations of chs. NR 113, 114 or s. 29.601, Stats., in any 3-year certification period. Enforcement may be taken against the operator, the operator-in-charge responsible for the operator or both. Each violation shall count against the business for purposes of license renewal as specified in s. NR 113.05 (3), Wis. Adm. Code (reference s. NR 114.24, Wis. Adm. Code).

Septage Certified Operator Continuing Education

The department requires that septage operators obtain certified operator continuing education (compliance) hours that focus on:

  • Wisconsin Administrative Code compliance (chs. NR 113 and NR 114, Wis. Adm. Code),
  • Other relevant provisions in Wisconsin Administrative Code and/or
  • New technological innovations in the septage industry.

Note: Certified operator continuing education is commonly known as compliance training.

The department shall develop or approve training relevant to the septage servicing profession sufficient to fulfill the continuing education requirements. Trainings shall be offered at frequencies and at diverse locations around the state so as to facilitate fulfillment of these requirements (reference sub. NR 114.23(3), Wis. Adm. Code).

Additional general septage-related knowledge and skills (examples: CPR, first aid and confined space entry training) may be eligible for general continuing education hours. General continuing education hours are different from compliance continuing education hours (see sections below for more details).

Training History Report

An operator's continuing education hours are tracked electronically, and available on the operator's Training History Report. Operators can access a copy of this report through the ELC Operator Certification Lookup.

Compliance Training Calendar

Operators can access the department's Operator Certification Event Calendar for a list of upcoming compliance training courses. Under "Certification Type", the operator should select "Septage Service."

Compliance Training Requirements

Certified Operator (Grade T and Grade L). All Grade T and Grade L septage operators shall obtain 3 hours of certified compliance continuing education within the 3-year term of the certification (reference: sub. NR 114.23(1), Wis. Adm. Code).

Master Operator (Grade T and Grade L). All Grade T and Grade L master operators shall obtain 18 hours of department-approved continuing education, including not less than 3 hours of certified compliance continuing education, within the 3-year term of the certification (reference: sub. NR 114.23(2), Wis. Adm. Code). Note: The additional 15 hours may be in the form of compliance credits, general septage credits or a combination of compliance and general credits.

IMPORTANT: An operator's credits must be earned in the 3-year period prior to operator certification renewal. For example, if a master operator was certified March 1, 2023, the operator must earn 3 compliance hours and 15 general hours before their certification expires March 1, 2026. Additional credit hours do not carry over and may not be used for a future certification renewal.

Compliance Continuing Education Hours

Compliance hours are earned by attending pre-approved training specific to state and federal septage rules, such as

  • Environmental Protection Agency's (EPA's) rule 40 CFR Part 503, or
  • Wisconsin Administrative Rules chs. NR 113 and NR 114.

Note: Other training courses on the calendar may be approved for general septage hours; general septage hours are not compliance hours.

The department provides at least four training courses per year:

  • Winter Wisconsin Liquid Waste Carriers Association (WLWCA) conference,
  • Summer WLWCA conference, and
  • Two master operator (MO) training courses. Notes: One in-person MO course is typically held in central Wisconsin. One MO course is typically virtual.

The above training opportunities are posted on the department's Operator Certification Event Calendar.

General Continuing Education Hours

Continuing education opportunities approved for general septage continuing education hours include, but are not limited to, department-approved:

  • Wisconsin Department of Natural Resources (WDNR) approved training classes, workshops and seminars,

Operators may either include updated contact information with their renewal materials or email DNROpCertSeptage@Wisconsin.gov. It is recommended that the operator provide their full name and operator certification number to ensure timely updates to the department's database.

Septage Operator-In-Charge (OIC)

A septage operator-in-charge or OIC is an individual that has been designated by the owner to be in direct, responsible charge of the septage business (reference: NR 114.153(5), Wis. Adm. Code). Only operators with the master operator certification may be designated as the OIC of a septage business.

Each septage business must designate a certified master operator as the operator-in-change (or OIC). That OIC must be of appropriate grade based upon the type of business and the method of septage disposal (example: Grade L master operator designated as OIC for septage business that landspreads septage).

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.

Septage Portable Restroom Servicing Assistants (PRSAs)

Portable Restroom Servicing Assistants (PRSAs) may service portable restrooms, including the maintenance and transportation of the restrooms and the septage from them without being certified under ch. NR 114, Wis. Adm. Code.

IMPORTANT: A PRSA may not service or dispose of septage waste from a septic tank, holding tank, dosing chamber, grease interceptor, seepage bed, seepage pit, seepage trench, distribution cell or any other component a private onsite wastewater treatment system (or POWTS). A PRSA may not land apply any septage removed from portable restrooms (reference: sub. NR 114.16(3), Wis. Adm. Code).

Responsibility For PRSAs

A OIC does not need to register a PRSA with the department. A OIC does not need to notify the department when a PRSA joins or leaves the business.

A PRSA is considered to be working under the certification of the operator-in-charge or OIC. The OIC is responsible for their actions (reference: sub. NR 114.16(3), Wis. Adm. Code).

Farmer Non-Commercial Septage Operator Certification

Sub. 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.

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). Specifically:

  • The septage is removed from a septic tank that is located on the same parcel of land where the septage is disposed, and
  • The farmer complies with all applicable statute and rules for servicing and land application.

IMPORTANT: While a person may be exempt from the business license requirements by s. 281.48, Wis. Stats, servicing shall be in conformity ch. NR 113, Wis. Adm. Code.

Application And Approval

Applicants should complete the Septage: Farmer Non-Commercial Septage Operator Registration Application (form 3400-194 AKA 194). This form can be downloaded from the Septage Operator Related Forms section. A completed application should be mailed to the regional septage coordinator (see Septage Contact section).

The department may provide a non-commercial registration number to allow the farmer to report private onsite wastewater treatment system (or POWTS) servicing events required under s. SPS 383.55, Wis. Adm. Code to governmental units under s. 145.01 (5), Wis. Stats.

Septage Non-Commercial Operator Lookup

The Septage Farmer Non-Commercial spreadsheet contains a list of approved non-commercial septage operators.

Compliance Issues

A person that fails to comply with the requirements of ch. NR 113, Wis. Adm. Code may be subject to enforcement under s. NR 113.14, Wis. Adm. Code. Please see the Septage Enforcement section for more details.

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 (USEPA) Enforcement. The USEPA 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 3-year certification period.

Master septage operators are required to obtain 3 septage compliance credits and 15 general septage credits during the 3-year certification period. Without the proper continuation hours, the department is unable to renew a certification for an individual and the certification lapses.

Operator Revocation And Non-Renewal

There are numerous ways an operator certification can be revoked or non-renewed. These ways are identified in: ss. 145.20, 281.17, and 281.48, Wis. Stats. Examples, include:

  • Use of deception or any form of dishonesty when taking an examination, or removes examination material from an examination site;
  • Operator demonstrates incompetence to perform septage servicing as required by ch. NR 113, Wis. Adm. Code; and/or
  • Operator falsifies any required applications, operating records or any other records submitted to the department.

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.

The department shall revoke an operator's certification and may not issue or renew a certificate for septage servicing for a period of 2 years if an operator has accumulated 6 or more violations of chs. NR 113, 114 or s. 29.601, Stats., in any 3-year certification period (reference sub. NR 114.24(1), Wis. Adm. Code). Enforcement may be taken against the operator, the operator-in-charge, owner, business or any combination. Note: Each violation shall count against the business for purposes of license renewal as specified in s. NR 113.05(3), Wis. Adm. Code.

Conversion Of Grade L Operator Certification

The department may convert an operator or master operator Grade L certification to a Grade T certification due to sanctions levied under s. NR 114.24, Wis. Adm. Code.

Septage Operator Related Forms

This section 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).
