they are suitable.
(c)
150. When in the opinion of the Community Planning
Commission suitable material is not available within the limits of
the highway location to form the subgrade or subbase, the contractor
shall obtain such additional material as may be approved by the Community
Planning Commission from other sources in accordance with this section.
