Minimal regulation. Wyoming is one of the most permissive states for contractor regulation, delegating licensing almost entirely to local jurisdictions. Wyoming OSHA state plan provides worker safety oversight.
Wyoming leaves contractor licensing to counties and municipalities; only electricians have state-issued licenses statewide; standard state business registration.
Wyoming DEQ Solid and Hazardous Waste Division (SHWD) oversees; specific medical waste transporter registration uncertain.
Numerical cleanup standard exists (0.75 µg/100cm²); no known contractor certification program.
Wyoming has an OSHA-approved State Plan (WY OSHA) covering private and public sector workers.
No state-mandated minimum specific to biohazard work beyond local contractor requirements.
Verify before operating: Licensing requirements change frequently. Confirm all information directly with Wyoming state agencies before starting or expanding operations. This page was last reviewed April 2026.
