SSTS Business Licensing, Individual Certification and Enforcement
SSTS Business Licensing

All private businesses in Minnesota that design, install, repair, maintain, operate, or inspect septic systems must be licensed with the MPCA. Local and state government employees do not require a license, but must obtain Individual Certification in the specialty area(s) applicable to the work being conducted, and are referred to as Qualified Employees (QE). Local units of government cannot require additional local licenses for septic system professionals in Minnesota.
All Minnesota-licensed businesses must employ at least one ‘Designated Certified Individual’ (DCI) for each specialty area offered by the business. A DCI is a person certified with the MPCA SSTS program that has attended training, passed exams, and gained experience in the specialty area for which he or she is seeking licensure.
There are four requirements for a business license application:
- Proof of an SSTS Surety Bond
- Proof of general liability insurance
- $200 fee for each license specialty area per year ($400 maximum)
- Proof of employment of at least one SSTS Certified Individual per specialty area

Need-To-Know
The Need-To-Know (N2K) process is a stakeholder-driven job analysis procedure used to define what SSTS practitioners ‘need to know’ to effectively and efficiently practice their profession. The job analysis process is an important way to define and continuously improve SSTS curriculum and exams. The Task Analyses below are working documents that outline tasks in which SSTS practitioners are expected to be competent. If you would like to comment on existing N2K criteria or are interested in participating in N2K committees, contact Charlie Thompson at charlie.thompson@state.mn.us or Nick Haig at nick.haig@state.mn.us.

Enforcement
Due to their permit and ordinance authorities, local units of government are often the first line of action for licensing enforcement activities. The MPCA provides enforcement when local actions are ineffective or local governments or SSTS professionals need assistance. The MPCA investigates written complaints with sufficient evidence and retains the authority to suspend, restrict or revoke a license.
- Minnesota Rules Chapter 7083.2020

- MPCA Enforcement action news releases
The MPCA has a process that allows local units of government to request that the MPCA be the lead on a local SSTS enforcement issue. To facilitate this process, the MPCA has an enforcement review process which includes the following referral document:
