Material Sources

Material sources are locations, typically outside the highway corridor easement, from which rock and soil materials may be mined and processed for new construction or maintenance needs.  Material sources are used for many of ADOT’s highway construction projects. They may also serve ADOT as repositories for excess materials generated by construction or maintenance activities.  For any given project, the contractor supplies the needed materials, by using either an ADOT-licensed source or a contractor-furnished source. Whether the material source is an ADOT-licensed source or contractor-furnished source, it requires environmental approval prior to every use.

ADOT-Licensed Material Sources

These material sources are planned, developed, and administered by ADOT. ADOT can be the outright owner of such sources, or they can be on government lands by easement. The clearance document includes the Material Source Checklist. The checklist and clearance memo templates will assist practitioners and contractors to prepare environmental documentation for ADOT licensed material sources.

Contractor-Furnished Material Sources

These material sources are privately owned by the contractor or other private party. The environmental clearance process for the initial use of a particular material source requires the submittal of the Material Source Environmental Analysis Application. For subsequent uses of the same material source, submittal of the Environmental Analysis Update form may be appropriate. Contractor-Furnished Material Sources must go through a multiple-step process in order to obtain environmental clearance for use on ADOT projects.

Guidance and Documentation

Material Source Environmental Analysis Application - To be used by all applicants

All applicants shall use this Material Source Environmental Analysis Application form to initiate the ADOT Environmental Analysis process in accordance with the ADOT specifications. As a reminder, state, vicinity, and site maps are required with each application. Be sure to illustrate the haul road on the vicinity and site maps. Please note that the cultural resource survey and other questions, such as the ones pertaining to Threatened & Endangered Species or Clean Water Act Permitting, require that the haul road and the entire proposed material source area be included in the evaluations and surveys.

Material Source Environmental Analysis Update - For contractor provided material

The ADOT contractor electing to provide material from a previously approved contractor-furnished source must submit the Material Source Environmental Analysis Update form to the project Resident Engineer.
