Current through Register Vol. 54, No. 44, November 2, 2024
(a) An application shall contain a
description of the geology and groundwater in the proposed permit area and
adjacent areas down to and including the lowest aquifer that may be affected by
the facility, including the following:
(1)
The results of a sufficient number of test borings and core borings to
accurately characterize geology, soils, groundwater flow, groundwater chemistry
and flow systems of the proposed permit area and adjacent area, which shall be
at least three test borings. At least one test boring shall be a core boring.
The applicant shall include the actual surface elevations of the drill
holes.
(2) Stratigraphy,
lithologic, physical characteristics and thickness of each stratum, including
the location and depth of aquifers.
(3) The hydrologic characteristics of each
acquifer described in paragraph (2), including field test data for hydraulic
conductivity, storage coefficient and transmissivity, groundwater hydraulic
gradient and velocity. The description of these characteristics shall be based
on multiple well aquifer tests. Alternative techniques approved by the
Department may be employed when multiple well aquifer tests are not feasible.
The application shall include the procedures and calculations used to determine
these characteristics.
(4) The
geologic structure within the proposed permit area and adjacent area, and its
relation to the regional geological structure.
(5) The uses of each aquifer.
(6) Aquifer characteristics necessary to
accurately describe three dimensional groundwater flow through the proposed
permit area and adjacent area, including storage and discharge
characteristics.
(7) Extent of coal
and noncoal mineral deposits and mines within the proposed permit area, as
required by §
273.120 (relating to mineral
deposits information).
(8) The well
head protection areas in accordance with §
109.1 (relating to definitions)
that may be impacted by the facility.
(9) A groundwater contour map based upon the
highest groundwater level recorded monthly in each boring for the previous
year. The Department may require more frequent measurements after significant
precipitation events.
(b)
A boring or coring not cased and capped or not to be used for groundwater
monitoring shall be grouted shut or otherwise sealed in a manner approved by
the Department.

of geology, soils and hydrology-general
requirements).
