The Idaho Environmental Guide is a resource for local government officials to assist in managing a community's environmental responsibilities. It should be consulted before approving projects to understand the impacts to air, water, and/or land that could affect the health, welfare, and sustainability of your community.

Local government entities often own and have primary responsibility for wastewater and storm water systems, drinking water systems, and solid waste disposal services and systems, among other areas of environmental concern. Through planning and zoning actions, operational ordinances, and inspections, local governments also directly influence business development in their boundaries. Local governments share a mutual responsibility toward sustainable development and protection of air, land, and water.

Planning and zoning is a local authority that DEQ does not address. DEQ plays a complimentary role, but does not make land use decisions. Note that DEQ's approvals of activities under its regulatory authority are still subject to local planning and zoning restrictions, which may be more or less limiting.

When projects overlap local boundaries or affect areas outside of your jurisdiction, coordination with the corresponding local government is encouraged. Reference the Idaho Local Land Use Planning Act (I.C. § 67-6537), which outlines requirements for local governing boards to collaborate and cooperate on projects.
