(a) An application shall contain a
description of the chemical characteristics of each aquifer in the proposed
permit area and adjacent area, based on at least two quarters, one of which
shall include the season of highest local groundwater levels. This description
shall be based on quarterly sampling and analysis from each monitoring well for
the following parameters:
(1)
Ammonia-nitrogen, bicarbonate, calcium, chloride, chemical oxygen demand,
fluoride, nitrate-nitrogen, pH, specific conductance, total dissolved solids,
total organic carbon, turbidity, iron, manganese, sulfate, total alkalinity,
potassium and sodium.
(2)
Groundwater elevations in monitoring wells recorded as a distance from the
elevation at the well head referenced to mean sea level based on United States
Geological Survey datum.
(3) Total
and dissolved concentrations of each of the following: arsenic, barium,
cadmium, chromium, copper, lead, magnesium, mercury, selenium, silver and
zinc.
(4) Tetrachloroethene,
trichloroethene, 1,1,1 trichloroethane, 1,2 dibromoethane, 1,1 dichloroethene,
1,2-dichloroethene (cis and trans isomers), vinyl chloride, 1,1 dichloroethane,
1,2-dichloroethane, methylene chloride, toluene, ethylbenzene, benzene and
xylene.
(5) Other constituents
contained in the waste that may leach into the environment, as determined under
§
287.132 (relating to chemical
analysis of waste).
(b)
For residual waste disposal impoundments permitted by the Department after July
4, 1992, 1 year of data consistent with this section shall be taken prior to
the disposal or storage of a waste at the facility. If the facility is to be
permitted under §§
287.111 and
287.113 (relating to notice by
impoundments and unpermitted processing or disposal facilities; and permitting
procedure for unpermitted processing or disposal facilities), the 1 year of
data shall be taken prior to issuance of the permit.
(c) Monitoring wells under this section shall
be designed, constructed and maintained in accordance with §§
289.261-
289.263 (relating to general
requirements; number, location and depth of monitoring points; and standards
for casing of wells). Sampling and analysis shall be conducted in accordance
with a plan approved by the Department under §
289.152(b)
(relating to water quality monitoring plan).
