On November 2, 2006 EPA signed an Action Memorandum approving a removal response action for the excavation and proper disposal of contaminated soils, the installation of concrete and asphalt caps at the two (2) acre former gas plant property, and the installation of four (4) additional monitoring wells for the dissolved phase groundwater. The subsurface soils at the site are contaminated with PAHs and metals, and the site groundwater contains a dense non-aqueous phase liquid (DNAPL) contaminated with coal tar and PAHs. The dissolved phase groundwater is contaminated with benzene, toluene, ethylbenzene, and xylene (BTEX), PAHs and cyanide and is a source of contamination for the pre-treated municipal water supply. On November 29, 2006 EPA entered into an Administrative Order on Consent (AOC) with Potentially Responsible Parties (PRPs) Pennsylvania Power and Light (PPL) Corporation and UGI Utilities (UGI), for their performance of a removal response action at the Site. EPA issued notice to proceed on March 16 2007, the PRP's contractor mobilized to the Site on March 19, 2007, and completed construction of the removal action on September 18, 2007. . The U.S. EPA Record of Decision (ROD) and Preliminary Close-Out Report (PCOR) for the Site were both signed on September 24, 2007. The ROD’s selected remedy is: No Further Action for site soils, long-term groundwater monitoring, operation and maintenance of caps constructed pursuant to the removal action, institutional controls (ICs) and a Technical Impracticability (TI) waiver for restoration of Dense Non-Aqueous Phase Liquid (DNAPL) groundwater. The PCOR signifies the Site has achieved construction complete status. The removal actions conducted by PRPs included design and construction features in anticipation of site reuse. More information on the removal action may be found at EPA OSC web site
