The RP’s contractor conducted 24-hour monitoring of the sumps and intercept trench.  Pumping operations from the sumps, both inside and outside of the containment area and the intercept trench, occurred as needed.  All of the water that was collected was pumped into on-site tanks and will be tested and disposed of in accordance with applicable state and federal requirements. 

The contractor removed the trench boxes from the intercept trench and installed a High Density Polyethylene (HDPE) liner in the trench.  A geotextile fabric layer was installed on top of the HDPE liner and the trench was filled with gravel.  A 36” vertical pipe was installed in the sump created in the trench.  The water was pumped from the sump in the trench to tanks in the containment area on an as-needed basis.  The pumping frequency varied between approximately 3 to 7 hours, depending on precipitation events, snow/ice melting, and whether they are pumping water from sumps/culverts within the containment area.    

At the request of WVDEP, the facility installed an inflatable plug in the oil/water separator sump after WVDEP reported observing water leaking from the outfall.   

The facility shipped a trial load of approximately 3,000 gallons of waste water from the Poca Blending Facility (Poca) in Poca, WV to Waste Management DSI in Hurricane, WV (DSI) for solidification.  The shipment went as planned and a sample of the solidified product was collected.  The facility was awaiting Synthetic Precipitation Leaching Procedure (SPLP) test results for the sample as well as legal approval to ship the remainder of the waste water from Poca to DSI.  A 55-gallon drum was also filled the waste water at Poca Blending to be stored for future use. 

A load of clean fill material was delivered to the site for use in the ditch that was cleaned out along Barlow Road.  The fill material was spread in the ditch to a grade to improve drainage flow in the ditch and resuce water ponding.

The facility removed approximately 6-9” of soil and gravel from the vac trailer parking area.  The soil was removed to reduce the possibility of cross contamination from the old loading of trucks in this area.  During excavation, there was a strong petroleum odor and black stained soil was observed.  There was also an MCHM odor observed.  The soil and gravel was placed in roll offs for disposal at the landfill.  The area was backfilled with clean gravel and the trailer was placed back in the area.

The facility excavated an area outside the east containment wall.  They were attempting to locate the end of the culvert pipe to determine the source of the off-site water.  During the excavation, water began pouring from beneath the footer outside on the containment wall into the excavated hole. The hole was left open and the water eventually flowed back inside the containment wall via the culvert pipe where the water was being pumped to storage. The contractor moved inside the containment wall and excavated at the same location but no pipe or water was uncovered. A bed of gravel under the containment area may be the source of the water.

The facility’s contractor replaced the dirty booms in the river.  They reported no visible sheen on the river water or any scent of product at the river during the trade out of booms.

As of the end of this reporting period, 77,836 gallons of product remain at the Poca location in double walled Baker Tanks.

• Divert the runoff water that is entering the containment area;
• Maintain/improve as necessary the intercept trench between the Site and the Elk River;
• Dismantle the MCHM tanks on Site and provide the necessary portions of the tanks to investigative entities;
• Remove the three MCHM tanks from the Site. 

• There is the possibility of an unknown amount of MCHM/PPH and potentially other chemical liquids may exist beneath the tank;
• There is an unknown amount of MCHM/PPH that has seeped into the soils/materials located along the river bank;
• There is a large amount of water (approximately 450,000 gallons), potentially contaminated with MCHM, stored in tanks on Site.
