Material
sources are used for many of ADOT’s highway construction
projects. For any given project, the contractor supplies the
materials source, by using either an ADOT source or a contractor-furnished
source. Whether the material sources are ADOT sources or contractor-furnished,
they require environmental clearance prior to use.
The
Environmental Planning Group oversees the preparation
of environmental documents for all material sources. These
documents insure that all relevant environmental factors are
appropriately addressed and mitigated.
For ADOT material sources, the primary document includes the
Material Source Environmental Determination. For contractor-furnished
material sources, the primary document includes the Material
Source Environmental Analysis Application (see photo
to the left).
Guidance for these documents are available for environmental
practitioners and contractors through the links in the right-hand
column of this web page. Since the level of documentation
differs between the ADOT and contractor-furnished material
sources, there are separate links for each material source
type.
