Universal Citation: 25 PA Code § 289.123

Current through Register Vol. 54, No. 52, December 28, 2024

(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).
