About the Idaho Department of Environmental Quality

Our Mission

To protect human health and the quality of Idaho’s air, land, and water.

Our Vision

An Idaho where the quality of our environment enhances healthy living and supports thriving communities.


DEQ is a state department created by the Idaho Environmental Protection and Health Act (Idaho Code Title 39) to ensure clean air, water, and land in the state and protect Idaho citizens from the adverse health impacts of pollution.

As a regulatory agency, DEQ enforces various state environmental regulations and administers a number of federal environmental protection laws including the Clean Air Act, the Clean Water Act, and the Resource Conservation and Recovery Act. DEQ manages a broad range of activities including:

  • Assessment of environmental problems
  • Oversight of facilities that generate air, water, and hazardous and solid waste pollution
  • Protection of air, land, and water quality
  • Prevention of releases and cleanup of contaminated sites
  • Education, outreach, and technical assistance to businesses, local government agencies, and interested citizens

The agency is committed to working in partnership with local communities, businesses, and citizens to identify and implement cost-effective environmental solutions.

He received his master of public administration from BSU in 2004.

DEQ's Communications and Outreach Program, an arm of the director's office,  assists in communicating DEQ's message to stakeholders, the regulated community, the news media, and the general public in a user-friendly way.

Emergency Response Overview

Emergency management activities in Idaho are coordinated by the Idaho Bureau of Homeland Security. Each state agency is to appoint at least one representative to train, exercise and participate in the State Emergency Management Program to facilitate emergency support and logistics in response to emergencies and disasters. In addition, each agency must develop and maintain an emergency operations plan to carry out the agency's response and recovery support functions and a Continuity of Operations Plan (COOP) to address how the agency will provide essential services to citizens during response and recovery and return the agency to normal operations. Learn about DEQ's specific responsibilities here.

Strategic Plans and Performance Measurement Reports

Each year DEQ develops a strategic plan to identify the agency's goals and objectives for the next and four subsequent fiscal years and the strategies it will follow to achieve those goals and objectives. As required by state statute, the plan is submitted to the Legislature. An overview of DEQ's current goals and links to the agency's strategic plans since 2001 are available here.
