Septage servicing operator certification |

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 for information on Training History Reports), and
Applicable renewal fee (see Septage Operator Fee Overview section).

The above information can be mailed to the address below:

Wisconsin Department of Natural Resources
Septage Certification - EA/7
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 [PDF] 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:

Note: A certification exemption is allowed for portable restroom servicing assistants (PRSAs). PRSAs must work under the direction of the OIC and are limited to only servicing portable restrooms and cannot landspread septage. See the Portable Restroom Assistants (PRSAs) section for more details.

Septage Operator-In-Trainings (OITs)

An operator-in-training or OIT is an individual considered to be doing septage servicing under the certification of the designated operator-in-charge (or OIC). IMPORTANT: The OIC is responsible for the actions of the OIT (reference: par. NR 114.16(2)(b), Wis. Adm. Code).

The OIC shall register the OIT by submitting the Septage: Operator-in-Training (OIT) Registration Application [PDF] (form 3400-174 AKA 174 Form). As part of this application, the OIC must identify if the applicant has been previously registered as on OIT pursuant to sub. NR 114.16(2), Wis. Adm. Code.

An OIT may engage in septage servicing for up to 12 months without being certified as a septage operator. For example, if an OIT registered March 1, 2023, the OIT registration would end March 1, 2024.

Five years after the end of the last OIT term (12-month term), a person that was registered with the department as an OIT may be re-registered with the department as an OIT and engage in septage servicing for up to 12 months without being certified (reference: par. NR 114.16(2)(a), Wis. Adm. Code).

Septage Operators

A certified septage operator is a person who has been issued a certificate by the department to do septage servicing (reference sub. NR 114.153(3), Wis. Adm. Code).

There are two general certification grades for septage servicing operators.

Grade T Certified Operator. A Grade T operator is certified to conduct all aspects of septage servicing except the land application of septage. To qualify for certification as a Grade T operator, a person shall pass the Grade T examination (reference par. NR 114.17(1)(a), Wis. Adm. Code).
Grade L Certified Operator. A Grade L operator is certified to conduct all aspects of septage servicing including the land application of septage. To qualify for certification as a Grade L operator, a person shall pass the Grade L examination (reference par NR 114.17(1)(b), Wis. Adm. Code).

A Grade L certified operator requests the department in writing to convert the certification to a Grade T certified operator; or
The department converts the certification as specified as part of enforcement under sub. NR 114.24 (2), Wis. Adm. Code.

Septage Master Operators

A master operator is a certified operator who has been issued a master operator certificate by the department (reference sub. NR 114.153(4m), Wis. Adm. Code). Only individuals with a master operator certification are qualified to be operators-in-charge (OIC). Generally, it takes a septage operator approximately 1-2 years to become a master operator. Operators should plan accordingly.

Grade T Master Operator. In order for a septage Grade T certified operator to become a septage Grade T master operator, the individual must complete the following tasks:

Submit a notarized 1600-hour work experience statement to the department for review and approval;
Participate in a mandatory master operator training class;
Pass the master operator Grade T exam and
Pay applicable fees. See Septage Operator Fee Overview section for more information.

Note: The class and examinations may be taken prior to obtaining the required experience.

Grade L Master Operator. In order for a septage Grade L certified operator to become a septage Grade L master operator, the individual must complete the following tasks:

Master Operator Class. The Master Operator Class is open to certified operators and master operators for a minimum of three compliance credits. It is recommended that operators attend the Master Operator Class prior to sitting for the Master Operator Exam. The DNR is required to offer the master operator class twice per year, and covers all topics relevant to septage servicing, land application and disposal (reference: sub. NR 114.18(3), Wis. Adm. Code). See the Septage Operator Exams section for more details.

Master Operator Certification Expiration Date. Upgrading to the master operator level does not change an operator's certification expiration date. Depending on when the operator upgrades, the number of credits they must earn prior to renewal is reduced. The number of required credits ranges from 3 to 18 credits, 3 of which must be compliance credits. The number of required credits for renewal is printed on the certificate issued when the certification is upgraded.

Conversion of Master Operator Grade L certification to Grade T certification. The department may convert a Grade L master operator certification to a Grade T master operator certification in any of the following circumstances:

A Grade L master operator requests the department in writing to convert the certification to a Grade T master operator; or
The department converts the certification as specified as part of enforcement under sub. NR 114.24 (2), Wis. Adm. Code.

Septage Operator-In-Charge (OIC)

An operator-in-charge is an individual that has been designated by the owner to be in direct, responsible charge of the septage business. Only operators with the master operator certification may be designated as the OIC of a septage business. See the Septage Operator-in-Charge (OIC) section for more details.

Operators should notify the Septage Operator Certification Program of any change in contact information (phone number, email address and mailing address). 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.

Emergency OIC Situation

The department developed guidelines, expectations and instructions to assist business owners when the only master operator (serving as OIC) exits from a licensed septage business due to an untimely death or temporary or permanent incapacitation. Please reference the Streamlined Variance Procedures for Emergency Operator-in-Charge (OIC) Situations [PDF] guidance document for more details.

OIC Grade L To Grade T Conversion

The department may convert a Grade L OIC to a Grade T OIC in any of the following circumstances:

A Grade L OIC requests the department in writing to convert the certification to a Grade T OIC; or
The department converts the OIC certification as specified as part of enforcement under sub. NR 114.24 (2), 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 [PDF] contains a list of approved non-commercial septage operators.

Note: Operator Certification staff are in-progress of updating this list. Please email DNROpCertSeptage@Wisconsin.gov to request a copy of the most recent version.

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.

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;
