Current Activities
On December 14, the PRP contractor flushed a portion of the storm sewers from Manhole (MH) #64 to MH #31 with 6,000-gallons of dyed water.  A vacuum truck located at MH #31 collected the 6,000 gallons for later disposal off-site.  Vacuum truck activities continued at various selected storm sewer manholes upstream of the sewer flushing activities.  Air monitoring activities by CTEH were continued.  At the ODOT ramp, the top portion of road bed was removed to allow access to the sand underbed near the water line excavation trench to allow for sloping of trench for general construction safety.  The slurry plug installed between MH #31 and the storm sewer outfall was removed, and that excavation is to remain open as a pre-river sewer sump to assist in collecting storm water in the event of a heavy rain event.  Additional booms were installed at the storm sewer outfall to the Maumee River.  The boomed area continues to be aerated to prevent the buildup of ice.  Geoprobe activities continue on and around the ODOT ramp and included a portion of the area located east of the storm sewers.  The location of the Enbridge pipeline previous (original) trenchline was identified using a Geoprobe and soil borings.  The length and location of the slurry wall was confirmed.  Air purging of the upper storm sewers continue with vapor capture cartridges (carbon units) at MH #54 and #52.

On December 15,  five booms were maintained at the outfall to the Maumee River.  The slurry wall excavation was left open for monitoring of the effectiveness of the vacuum truck operations at MH #31.  Vacuum truck operations continued at the storm-sewer and recovery trenches located within the diked area.  The water-line excavation trench was resloped, the top layer of roadbed-crushed rock continued to be removed, and the sand was sloped to reduce the hazards associated with an open excavation.  The upper storm sewer line from MH #55 to #51 was flushed using 6,000-gallons of water and some product was recovered.  OEPA Geoprobe activities, which included 22 borings to delineate the extent of contamination, were completed.  Air purging of the sewers continued.  TTL took over air monitoring activities from CTEH.

December 16, the excavation at the Maumee River was opened to monitor for product and observe any evidence of discharged product via the storm sewers.  Plugs were left in the storm sewers at MH #47 and #51.  PRP contractors transported contaminated soils to the landfill for treatment/disposal.  Excavation of the water lines continued.  Vacuum trucks continued to collect water and product from the sewers and trenches.  Air purging of the sewers continue.  TTL continued to monitor the perimeter of the site for vapors.  A PRP contractor continued to collect contaminated water for transportation to Usher in Michigan for reclaiming.

December 17, vacuuming of liquid from sewers, recovery wells, and trenches continued.  Free product was located in both recovery wells at MH #52.  Excavation on the water line trench continued.  The PRP contractor sampled the bottom of the 600 foot trench for contamination.  The trench was sampled every 10 feet starting from the north side wall south to the south side wall.  All samples were screened for VOCs using a MultiRae in the EPA laboratory trailer.  The PRP contractor continued to transport contaminated soils to the landfill.  Air purging of the upper storm sewers continued.

December 18, the PRP contractor began placement of 6 inch clay lifts in north end of water line trench.  Excavators compacted the clay, along with a sheepshook.  Clay was placed in the wall of the trench to plug gasoline from seeping out of wall, and to help stabilize the wall from slope failure.  Clay utilized for backfill material originated from the ODOT I-280 construction project.  After screening the samples on-site, one contaminated locations within the trench (from 310 to 350 feet) was re-excavated.  A second location from 530 to 600 feet was scheduled for excavation, but due to soil conditions and the danger associated with trench collapse, it was decided to install the barrier wall without additional excavation.  At this point, all clay lifts installed will need to be excavated due to the inability to gain compaction and moisture content requested by ODOT.  A vacuum truck continued to operate within the containment dike and at MH #51.  The plug at the Maumee River outfall remained in place.  Aerators continued to operate at the outfall.  To date, no sheen has been observed on the river. Air monitoring of the site continued.  

On December 19, placement and compaction of clay lifts in the water line trench continued.  Air monitoring on-site was continued by TTL. A vacuum truck was on-site pumping out MH #51 and within the diked area.

On December 20, installation of the clay barrier wall in the water line trench continued, along with compaction testing.  Air purging of the sewer system continued.  Air monitoring at the site by TTL continued.  PRP contractors continued to use vacuum trucks to collect water and product from various locations around the site.  Test pits were excavated within the diked area of the tank farm near Tanks #1, #2, #3 and #4.  Gasoline was collected in the various test pits.  Transportation of contaminated soils to the landfill continued.

On December 21, installation of the clay barrier wall in the water line trench continued, along with compaction testing.  Air purging of the sewer system continued at MH # 47 and #51.  Air monitoring at the site by TTL continued.  PRP contractors continued to use vacuum trucks to collect water and product from various locations around the site.  Gasoline was collected in the various test pits.  Transportation to the landfill of contaminated soils associated with the waterline trench was completed. On-site ground water monitoring wells were opened and investigated using microbailers to determine if any gasoline had migrated into three wells.  No gasoline was detected.

On December 22, installation of the clay barrier wall in the water line trench was completed.  Impermeability testing of the clay barrier wall was begun.  Air purging of the sewer system continued.  Air monitoring at the site by TTL continued.  PRP contractors continued to use vacuum trucks to collect water and product from various locations around the site.  Gasoline was collected in the various test pits.  

On December 23, the mass excavation of soils under the ODOT ramp began.  Contaminated soils were stockpiled on-site for transportation to the landfill in the future.  Impermeability testing of the clay barrier wall continued.  Air purging of the sewer system continued.  Air monitoring at the site by TTL continued.  PRP contractors continued to use vacuum trucks to collect water and product from various locations around the site.  Gasoline was collected in the test pits.  Additional vacuum trucks were located on-site to address and collect any additional infiltration associated with the warmer weather.

December 24, mass excavation of the ramp soils continued.  Vacuuming of the sewer system and backfill continued as did the air purging of the sewers.  TTL continued to monitor the air quality around the site.

Planned Removal Actions
-Continue GeoProbe activities to determine possible migration pathways, to define extent-of-contamination of the release, and to investigate the geotechnical composition of the containment area.

-Continue excavation activities around storm sewer systems to determine contamination migration pathways.

-Continue vacuum truck operations in the storm sewer system and monitor for potential product migration towards the Maumee River.

-Continue excavation and trenching activities to investigate, recover, and remove free product and contaminated soils.

-Begin discussions on the possibility of a long-term engineered product recovery system.

-Begin the installation of a new dike wall located closer to the tank system and away from the roadbed, water line, and pipeline.

-Begin to install vapor and/or product collection systems around storm sewer manholes.

Next Steps
-The PRP will excavate the product that has migrated off-site onto the ODOT property (under the ramp construction).  The estimated amount of soil removal (contaminated and clean) is approximatley 16,000 cubic yards.

-The PRP will continue to delineate the extent of the release within the tank farm.  The tank farm was divided into a grid to identify the boring location within the tank farm with a unique identifier.

Key Issues
-A draft Workplan has been submitted by the PRP, in accordance with the U.S. EPA Order.
