- Sitewide interim measures were evaluated in 2008 and additional data were collected to support interim measures evaluation, design, and implementation. Beginning in August 2008, an interim measure was conducted near SWMU 5 to address soil contamination. In December 2008, a design was prepared for an interim measure in the Ryan's Branch area. The design was finalized in 2009. Permits and approvals for construction of the interim measure were obtained from local, state, and federal agencies and stakeholders. Implementation of the interim measure was conducted from September 2009 to April 2010. In March 2010, planning was initiated for pre-design activities for SWMU 3 in concert with evaluation of possible interim measures for groundwater.
- In 2012 SWMU 1 was evaluated for a remedy consisting of protective cover and groundwater monitoring. Geotechnical borings were installed and finally the cover of SWMU 1 was enhanced to limit infiltration and prevent exposure. In late 2011 and early 2012, interim measures for SWMU 3 were evaluated and pre-design activities conducted. In September 2012, the evaluation of SWMU 3 was completed and an interim remedy proposed consisting of cover enhancement and groundwater performance monitoring.
- In 2012, an evaluation was conducted at the Proposed Reuse Area that included historical surface soil data and additional surface soil data collected. The purpose was to evaluate potential risks associated with a commercial/industrial worker exposed to surface soils throughout the site. Implementation of the interim measure was conducted from October 2012 to December 2012. In addition, additional surface soil sampling was completed across the site to support updates to the human health risk assessment. In September 2013, a design was prepared for an interim measure for the Central Waste-In-Place Area. Implementation of the interim measure was conducted from October 2013 to December 2013.
- The Corrective Measures Study is forecast to be submitted early first quarter 2014. It is expected that the entire site will go through public participation and final remedy selection in 2014.
- UCC's PTO Facility was used for cleaning tank trucks from 1975 to 1985. Prior to that operation, the facility was used for the disposal of various wastes from West Virginia UCC operations. The RFI Workplan described thirteen (13) Solid Waste Management Units (SWMUs) within the approximately forty (40) acre site.s.
- Based on available information there are no known imminent threats to human health or the environment at the PTO Facility. The main contaminants of concern are poly-chlorinated biphenyls (PCBs), polynuclear aromatic hydrocarbons (PAHs), naphthalene, bis(2-ethylhexyl)phthalate, carbon tetrachloride, benzene and trichloroethene. .
- Additional interim measures were performed in 2002 in order to meet the Environmental Indicator (EI) for Human Health. Additional fencing was installed around the facility in order to keep trespassers off the property. This was the final action necessary at the facility to meet the Human Health EI, which was recorded on September 19, 2002. In 2005, additional interim measures were conducted to stabilize an area of the site where subsidence was occurring and to prevent migration of contaminants into Ryan's Branch. In August 2005, UCC submitted the Groundwater (EI) to USEPA in and it was approved by USEPA in September 2005. n
