Commonwealth Court Upholds DEP’s “Soil-to-Groundwater” Theory as Basis for Daily Penalties Under the Clean Streams Law
In the latest development in parallel cases captioned EQT Prod. Co. v. Department of Environmental Protection which have been moving through Pennsylvania state courts and the Environmental Hearing Board ("EHB") since early 2014, the Commonwealth Court of Pennsylvania affirmed the EHB’s assessment of penalties totaling $1,137,295.76 against the hydraulic fracturing company, EQT Production Company (“EQT”), for contamination to groundwater arising from a leaking wastewater impoundment. EQT Prod. Co. v. Dep’t of Envtl. Prot., No. 844 C.D. 2017, 2018 WL 4289310 (Pa. Commw. Ct. Sept. 10, 2018). Specifically, on September 10, 2018, the Commonwealth Court held that the EHB did not commit an error of law when it held that, under Clean Streams Law (“CSL”), penalties could be assessed for every day that contamination entered the groundwater from soils “through fundamental hydrologic principles,” even if the initial spill event had ceased and there was no direct evidence of daily transmission of contamination from soil to groundwater.
