and reclamation activities. Such supplemental information may be based
upon drilling, aquifer tests, hydrogeologic analysis of the water-bearing
strata, flood flows, or analysis of other water quality and quantity
characteristics. Information shall be provided on water availability
and alternative water sources, including the suitability of alternative
water sources for existing premining uses and approved postmining
land uses.
(6) If the PHC determination required by this subsection
indicates that the proposed mining operation may proximately result
in contamination, diminution, or interruption of an underground or
surface source of water within the proposed permit or adjacent areas
which is used for domestic, agricultural, industrial or other legitimate
purpose, then the Commission may require that the applicant provide
information supplemental to that required under §12.130 (relating
to Alternative Water Supply Information).
(e) Cumulative hydrologic impact assessment.
(1) The Commission shall provide a probable cumulative
hydrologic impacts assessment (CHIA) of the proposed operation and
all anticipated mining upon surface- and ground-water systems in the
cumulative impact area. The CHIA shall be sufficient to determine,
for purposes of permit approval, whether the proposed operation has
been designed to prevent material damage to the hydrologic balance
outside the permit area. The Commission may allow the applicant to
submit data and analyses relevant to the CHIA with the permit application.
(2) An application for a permit revision shall be reviewed
by the Commission to determine whether a new or updated CHIA shall
be required.
