2.1.2 Current Response Activities

• KEMRON continues to transfer of hazardous liquid from Building #7 basement vaults to Frac Tanks. 

• MultiRae VOC Readings range from 2 ppm to 122 ppm in the hot zone depending on sludge/liquid agitation.
• On 06/06/14, one tanker transported approximately 5,300 gallons of haz code contaminated liquid waste from Building #7 Basement Vaults.   On 06/09/14, four tankers transported approximately 21,252 gallons of haz code contaminated liquid waste from Building #7 Basement Vaults.   However, there were mistakes made by the subcontractor laboratory (Original bid awarded laboratory) in presenting some of the lab data to the final disposal facility as well as the final disposal facility not properly reviewing the data.  When the disposal facility sampled and analyzed the tanker contents, the Cresol levels exceeded the facilities permitted treatment levels.  All liquid material was returned to the Riverside Site Frac tanks on 06/10/14.
• On 06/11/14, samples were obtained for analysis from the staged solid pile from Vault #1 as well as wet sludge samples from Vault #1 pit.
• On 06/13/14, the first section of the concrete floor was cut and removed from Vault #2.  Solid material removal from Vault #2 commenced.  This material will be staged separately than Vault #1 and will be considered a separate waste stream. 

• KEMRON continues to transfer of hazardous liquid from Building #7 basement vaults to Frac Tanks. 

• MultiRae VOC Readings range 1 ppm to 129 ppm in the hot zone depending on sludge/liquid agitation.
• On 06/16/14, one tanker transported approximately 5,160 gallons of haz code contaminated liquid waste from Building #7 Basement Vaults.  
• On 06/17/14, one tanker transported approximately 5,850 gallons of haz code contaminated liquid waste from Building #7 Basement Vaults.
• On 06/18/14, two tankers transported approximately 10,597 gallons of haz code contaminated liquid waste from Building #7 Basement Vaults.
• On 06/19/14, two tankers transported approximately 10,720 gallons of haz code contaminated liquid waste from Building #7 Basement Vaults.
• On 06/20/14, one tanker transported approximately 5,475 gallons of haz code contaminated liquid waste from Building #7 Basement Vaults.  This will be the last tanker of liquid waste until after the remaining contents in the Frac tanks are filtered to lower solid percentage.  The disposal expense of the hazardous code liquid accumulated has been a lot higher than anticipated due to high solids and the high concentrations of Cresol.  Lab results were received for the staged solid pile from Vault #1 as well as wet sludge samples from Vault #1 pit.  Due to the problems with the subcontractor laboratory (Original bid awarded laboratory), another laboratory will be used for disposal analytical analysis.  Therefore, the solid samples remaining at this laboratory were forwarded to another laboratory (Original bid/2^nd laboratory) for comparative analysis.  Lab results anticipated by 06/26/14.
• On 06/20/14 around 4:45 pm, there was a water line break on Riverside Avenue and all water to the Riverside Industrial complex was shut off.

• KEMRON continues to transfer of hazardous liquid from Building #7 basement vaults to Frac Tanks. 

• MultiRae VOC Readings range from 1 ppm to 49 ppm in the hot zone depending on sludge/liquid agitation.
• On 06/23/14, the water line on Riverside Avenue was repaired and service was restored around 12:00 PM.  Frac #1 liquid was sent out for confirmation analytical to the new laboratory (Original bid/2^nd laboratory).  Results due back by 06/27/14.
• On 06/24/14, KEMRON observed an increase in the liquid level of Building #7 Vault #2.  OSC and KEMRON performed a Level B PPE entry into Building #12 Basement.  One of the remaining investigations for the removal action was to enter an underground passageway between Building #12 and Building #7.  During the investigation it was noted that the water level was a lot higher than it should be; especially with no current rain events.  In the past, the basement held water briefly but then the water receded (Unlike Building #7 Basement which holds the liquid).  It was never determined if the water seeps through the basement walls to surrounding subsurface soil or makes it way to Building #7 (Hence the investigation of the passageway).  This water level was about 10 inches.  This level is higher the levels initially encountered when EPA conducted first remove action entry in 2011 post Hurricane Irene.  The doorway to the tunnel was almost entirely submerged (the door entrance is lower than the main floor of the basement).  It was also observed that the two tanks (which EPA removed the product from during initial removal phase) were cut up for scrap by trespassers (this occurred between the demob in May 2012 and mobilization in April 2014).  Lastly, the sound of water draining was identified.  Since there were no recent rain events, it was highly unlikely that water would be coming from upper floor levels.  A charged city water line was observed pouring water into the basement.  When the valve at the end of the pipe was closed, a hole in the metal piping started spraying water from this pressurized line.  It was assumed that this new water flow was a result of the water line repair on 06/23/14.  OSC reached out to Newark contacts and requested an immediate response.  Newark Water and Sewer Department responded later that evening and shut off the valve that they believed supplied the water.  They came out late yesterday…and then again earlier this morning.  This should eliminate the water issue, allow us to pump out Building #12 Basement and then start the investigation. 
• On 06/25/14, OSC and KEMRON performed another Level B PPE entry into Building #12 Basement.  The city water pipe continued to flow water.  Newark Water and Sewer Department returned to the site and open/resealed known valves.  A second entry by OSC and KEMRON was conducted and the pipe was still observed to be pressurized and leaking.  Several trouble shooting efforts by Newark Water and Sewer Department were attempted with no success.  Eventually, a repair band was placed over the damaged area of the water line and the valve at the end of the line closed.  The water flow appears to be stopped.  Pumping of the water from Building #12 Basement has commenced.
