25 Pa. Code § 90.35 - Protection of the hydrologic balance
(a) An application shall contain a detailed
description, with appropriate maps and cross-sections, of the measures to be
taken during and after the proposed coal refuse disposal activities, in
accordance with the performance standard of Subchapter D (relating to
performance standard for coal refuse disposal), to ensure protection of:
(1) The quality and quantity of the
groundwater, both within the proposed permit area and adjacent areas, from
adverse effects of the proposed coal refuse disposal activities.
(2) The rights of present users to surface
and groundwater.
(b) Each
application shall also contain the following:
(1) A plan for the control, in accordance
with Subchapter D, of surface and groundwater drainage into, through and out of
the area proposed to be affected by coal refuse disposal activities.
(2) A plan for the treatment, in accordance
with Subchapter D, of surface and groundwater drainage from the area to be
affected by the proposed coal refuse disposal activities, and proposed
quantitative limits on pollutants in discharges as provided in §
90.102 (relating to hydrologic
balance: water quality standards, effluent limitations and best management
practices).
(3) A plan for
collecting, recording and reporting of groundwater and surface water quality
and quantity data in accordance with §§
90.115 and
90.116 (relating to hydrologic
balance: groundwater monitoring; and hydrologic balance: surface water
monitoring). The plan shall identify monitoring locations and sampling
frequency, and logically relate to the determination of the probable hydrologic
consequences in Subsection (c).
(c) A determination of the probable
hydrologic consequences of the proposed coal refuse disposal activities on the
proposed permit area and adjacent area, with respect to the hydrologic regime
and the quantity and quality of water in surface and groundwater systems under
all seasonal conditions, including total dissolved solids, total suspended
solids, total iron, pH, total manganese, acidity, alkalinity, sulfates and
other parameters required by the Department.
(d) A plan shall contain a description of
possible alteration in the site development plan or method of disposal, in
response to adverse impacts on the hydrologic balance as indicated by the
groundwater monitoring system.
