1 The Administrator may exempt the
Applicant from this requirement if the Applicant demonstrates that
it proposes to mine a natural sand and gravel deposit or formation.
If the sand and gravel consists of previously extracted and stockpiled
materials, then the requirement applies unless the Applicant demonstrates
to the Administrator’s satisfaction that the material it is
not composed of and does not include previously extracted acid-generating
ore, overburden, tailings, waste rock, or other material extracted
in connection with a mineral resource extraction or processing operation.
