Jefferson County

Jefferson County This is the official page of the Jefferson County Idaho government. Please follow us! Jefferson County Idaho is the heart of the upper Snake River Plain.

We strive to provide relevant, accurate, and useful information to our residents and visitors. Agriculture is the mainstay of the economy, and the county is a bedroom community for employees of the many education, government, manufacturing, and research sector jobs all around northeast Idaho. This page is operated, monitored, and maintained by the Jefferson County government, including the Commiss

ioners, Clerk, Assessor, Treasurer, Prosecutor, and Sheriff, as well as departments working under the authority of each elected official. We invite civil conversation, requests for information, and feedback on our work.

Beginning June 1, updated landfill fees will take effect following approval during a public hearing before the Board of County Commissioners.

The updated fee schedule includes adjustments to in-county organic waste disposal, out-of-county disposal, and commercial hauler fees as part of an overall review of landfill operational costs. Rather than increasing costs broadly across all taxpayers, the approved changes are structured as user-based fees tied more directly to use of the service.

The County Line site operates as a construction and demolition landfill. Under DEQ regulations, organic waste such as grass, leaves, and branches cannot be buried onsite and must be hauled to the Circular Butte facility for disposal and processing. Previously, revenue from out-of-county waste helped offset a portion of the county’s solid waste operational costs. However, with the opening of the new regional landfill, that revenue source is no longer available.

Residents may continue to dispose of organic & household waste at the Circular Butte Landfill at no charge.
