Our team provides guidance and assistance to help you understand state rules and regulations, including training videos and checklists.

Find out more about what we do below:


We perform compliance inspections on the following sites: 

  • Open and closed municipal landfills
  • Industrial landfills
  • Construction and demolition landfills
  • Solid waste transfer
  • Treatment and storage facilities
  • Hazardous waste generators
  • Treatment, storage and disposal facilities
  • Used oil generators
  • Asbestos management facilities

Enforcement Actions

We issue both formal and informal enforcement actions. Informal actions generally involve a letter of violation and warning. Formal actions include issuance of Notices of Violation (NOV), Cease & Desist Orders, and Referral for Penalty to the Wyoming Attorney General’s Office.


Formal enforcement actions are used to deter problem violators and are used only after all efforts have been made through conference and conciliation to return the violations to compliance.

Solid and Hazardous Waste Complaints

Our team responds to solid and hazardous waste complaints and we conduct follow-up inspections as needed to ensure compliance.
