2.1.2 Current Response Activities

• KEMRON continued to transfer of hazardous liquid from Building #7 basement vaults to Frac Tanks.
• Sludge removal started on 06/13/14 in Building #7 Basement Vault #2 (Side closest to Building #12/West Side) and continued through this date range.  The crew and staff will continue to work in Level B PPE during this operation.  Crew is encountering liquid, sludge, solid and crystalized material. 
• MultiRae VOC Readings range from 0 ppm to 30 ppm in the hot zone depending on sludge/liquid agitation.
• Sludge has been removed and relocated for solidification from all five Frac tanks that were on site.  Three Tanks were cleaned and demobed from the site during previous report time range.  The two remaining Frac Tanks were used for collecting and staging the remaining liquid during the removal.  Once settled, the liquid will be filtered and transferred to the second Frac Tank.  This lowers the solid material in the liquid and lessen the costs for disposal.  All Frac tanks were cleaned and demobed from site by 08/2014.
• On 08/19/14, framing in Vault #1 complete. Center pump area-pumps removed.
• On 08/20/14, framing continued in center pump area and Vault#2. Concrete poured in Vault #1 followed by the center pump area and finally Vault #2.  The elastic polymer coating was applied to walls of Vault #1, Vault #2 and the center pump area to prevent any bleeding of waste absorbed into the existing vault walls.
• 08/21/14 thru 08/22/14-Demobilization of personnel, equipment and trailers.
• As of 08/22/14, approximately 10,860 gallons of liquid waste and 279,400 pounds of solid waste was transported to the approved disposal facilities during this time period.

2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)

EPA met with representatives from the City of Newark on the site on 11/09/09 to discuss the history of the site and the City's environmental assessment activities for the property to date. EPA will work with the City of Newark to identify PRPs for the site. During the 2/11/2011 recon the OSC discovered paperwork in a former office area bearing the logo of "Ted Frey Industries" and "Abrachem Logistics", both companies are believed to have operated at this location in the past. However, from prior knowledge at another Superfund site, both of these companies went bankrupt and ceased to exist years ago. The OSC has identified three other PRPs and will work with regional ORC to gather additional information regarding these PRPs.

On 12/15/11 OSC Daly attended an Enforcement Team Phone Conference.

USEPA Enforcement continues to work with USEPA ORC and PRPs.  This process will continue during the remedial phase at Riverside.
