The PRP Group assessed the drums and totes for leaks, bulges, and any other issues.  Areas within the secondary containment of the drums (A, B3, C3, D2) were documented to be addressed to clean-up of liquids from previously documented leaks inside the containment . Several totes were noted as having developed small leaks at the valve, possibly due to the heat and general condition of the valve; TO-046 non-flammable, non-corrosive, pH 5; TO-077 Flammable, and; TO-123 Flammable. These were documented as needing addressed for stabilization.

The perimeter of the Site was walked and each fence pole was visually inspected for stability. Issues noted with perimeter security included missing barb wire, poles that need replaced and/or reset in the ground, and areas of fence that will require re-alignment and adjustment due to normal wear and tear.  

As part of the baseline assessment, the secondary containment areas were measured for available freeboard: Bay 48 @ 17”; Bay 45 @ 17”; Sump Bay 36 @ 33”; Sump Bay 34 @ 25”; Sump Bay 35 @ 20”; STF @ 15”, and; NTF @ 14”.  The retention pond continued to have approximately 12” of freeboard.  The Bio-reactor was visually inspected for signs of deterioration. 

On 21 June 2012, EPA conducted oversight of  PRP Group operations to complete the Initial Site Assessment at the USOR property and the MCC property. During the assessment START-3 conducted written and photographic documentation of  the issues and concerns noted by the PRP Group. Items noted during the assessment at MCC included: 

A crack in the secondary containment wall on the north side of the Gravity Thickener  was noted where the pipe from the pump house dissects the wall. The crack goes through the wall yet no evidence of staining was located outside the wall. Available freeboard was 24".  A strong odor at the Oxygen Digester was noted. Air monitoring conducted using a PID monitor was non-detect for VOCs. 

The west and east gates at MCC East were noted as needing repaired for site entry: both have binds at the roller mechanism. The west gate at MCC West was noted as off the roller track and hung up on the concrete drive. During the inspection of the perimeter fence,  issues noted included missing barb wire, areas where the barb wire require tightening and both foot gates at the west side of East MCC will need hinge(s) tightened and/or replaced. 

Completing the  assessment at the USOR property, further evidence of trespass was noted, particularly in the warehouse. Chairs were located outside the lab, a ladder was placed at the electrical box, lab bottles were relocated, the contents of a small trash can was strewn near an area where two chairs were placed. Evidence of food and water consumption included a package of paper napkins and plates, used paper plates and an empty 1 gallon water container. The lab was vandalized: cupboard doors and desk drawers were left open and contents rifled through. A small transformer was also noted in the parking lot. 

Based upon the baseline site assessment, the PRP Group will begin conducting bi-weekly site visits and conducting site actions to address the issues noted above.
