Pool operator requirements in Wyoming

Wyoming names its accepted certifications directly in the rule text, which makes the state one of the more explicit ones to answer. If you run a public pool or spa in Wyoming, you answer to the Department of Agriculture, acting under the Public Pool and Spa Health and Safety Act.

Who this applies to

Wyoming’s rule covers general use and limited use public pools and spas: facilities open to the public or a defined group, such as apartment, hotel, gym, HOA, and municipal pools, not a private single-family backyard pool. Wyoming Statutes Title 35 Chapter 28 requires any person operating one of these facilities to hold a license and be knowledgeable of the rules that apply to it.

Does Wyoming require a certified pool operator?

Yes, and the rule spells out exactly which certifications qualify. The owner or operator of each general use or limited use public pool must have on staff or under contract, for each facility, a current certified operator. The requirement sits alongside Wyoming’s separate operator-license mandate: Title 35 Chapter 28 requires the person operating a public pool or spa to be licensed by the Department of Agriculture or a local health department, and to be “thoroughly knowledgeable” of the pool and spa laws and rules.

Which certification counts

Wyoming names three specific certifications and leaves the door open to equivalents:

• Certified Pool Operator (CPO), issued by the Pool and Hot Tub Alliance (PHTA)
• Aquatic Facility Operator (AFO), issued by the National Recreation and Park Association (NRPA)
• National Spa and Pool Institute (NSPI) Tech I Certification, an older designation still named in the rule
• Other equivalent certification the regulatory authority approves

In practice, the CPO and AFO are the two credentials most Wyoming facilities pursue today. If you are deciding between them, our CPO vs AFO guide compares the two directly, and how to become a CPO walks the course-plus-exam path.

The governing rule and agency

• Agency: the Wyoming Department of Agriculture administers the Public Swimming Pools program. In some jurisdictions a local health department handles licensing and inspection instead.
• Statute: the Public Pool and Spa Health and Safety Act, Wyoming Statutes Title 35, Chapter 28, sets the statutory framework, including the operator license requirement.
• Rule: the Department of Agriculture’s own administrative code chapter for public swimming pools implements the certified-operator and facility requirements under that statutory authority.

Renewal in Wyoming

Wyoming’s rule does not set its own recertification date for the operator credential; a CPO or AFO runs on its own national recertification cycle. Separate from the operator’s personal certification, the pool or spa facility itself must hold and maintain its own license from the Department of Agriculture or the local health department, which is a facility-level requirement rather than a personal renewal cycle.

How to comply in practice

1. Confirm your facility is a general use or limited use public pool or spa under Wyoming’s rule.
2. Get certified, most commonly the PHTA CPO or NRPA AFO, though the older NSPI Tech I or another approved-equivalent course also qualifies.
3. Have a certified operator on staff or under contract for the facility at all times the rule requires.
4. License the facility through the Department of Agriculture or your local health department, and keep that license current.
