POLLUTION REPORT

Subject: 

See previous POLREPs for Site description information.

Neither Stoney Creek Technologies nor any other Respondent to EPA's Orders or Potentially Responsible Party is conducting response actions due to bankruptcy, financial inability, or other reasons; therefore, EPA continues to use its own contractor resources to conduct response actions at the Site.  

-ERRS concluded the excavation of contaminated soil from the area adjacent to the waste water treatment plant (WWTP).  ERRS removed concrete and two tanks (T-955 and T-956) and completed excavating contaminated soil in the vicinity of the 'old' WWTP settling ponds.  Soil is being staged on-site pending disposal.  Soil excavation activities were conducted to reduce the risk of off site migration of oil due to discharge of oil to surface water.

- ERRS began transportation and disposal of the contaminated soil stockpile generated from excavation activities.  Approximately 484 tons of soil were transported off site for disposal during this work period.  

- During cleanout of the storage building adjacent to the command office, a small bottle of mercury was spilled. ERRS contractors immediately cleaned up the mercury, vacuumed the floors using a mercury vac and applied HGX to control the vapors. Currently, the room is being heated with a salamander heater in an effort to reduce vapors. START contractors have been routinely monitoring the room with a Lumex. Decontamination and monitoring will continue until mercury levels are at acceptable levels.  

- ERRS continued decontaminating exterior solid surfaces and drainage trenches.  This is being accomplished through scraping with hand tools and cleaning with hot water pressure washers.  Solid waste is being drummed for disposal and decon water is being consolidated in T-190.

- Waste water generated from decontamination operations is currently being stored in T-190 and T-198.    

- To date, approximately 21,600 gallons of material have been generated through pad and line clearing operations.  Arrangements for waste disposal is ongoing.

-  ERRS completed removal of materials from tank 956 during this reporting period.  With the exception of tanks being used to contain waste water, all planned tank clean out activities are now complete.

- ERRS completed the clean out of the main storm sewer line with a Jet Rod high pressure washer. Multiple passes of each sewer line section was conducted throughout a 3 week period. Wash water containing oily sludge was collected via vac trucks and pretreated in an onsite portable weir tank. From the weir tank, the wash water was then pumped into a dewatering box through a 100 micron dirt bag filter. The water is currently being staged in T-539, T-525 and T-526 pending transport to DELCORA for treatment.

- Over 250,000 gallons of water is currently being store on site which will require treatment.

- ERRS continued to operate the WWTP under procedures approved by the OSC.  The WWTP discharges to Stoney Creek.  Monitoring of pH and sampling of discharge is conducted routinely to ensure water quality meets applicable standards.  

- START Engineer completed engineering design for construction activities and installation of sewer pipe which will allow for the discontinuation of the WWTP and discharge of storm water to Stoney Creek.

- 23 totes and approximatly 60 drums containing acidic water were combined and stored into T-431A.  

- Approximately 240 waste drums, 1 roll-off, 250 tons of soil are currently staged on site. Transportation and disposal is currently being arranged by ERRS.

- Approximately 4,400 tons of soil and 4 roll-off boxes containing contents from T-956 were shipped off site for disposal during this reporting period.  To date, approximately 1,500,000 gallons of material have been removed from the site.  

- START contractors are performing air monitoring to ensure worker safety while performing tank entries and other activities that may present risk for worker exposure.

- Dispose of and/ or treat wastes staged on site.

- Patch concrete where sub-surface contamination poses a threat of surfacing and running off-site.

- Decontaminate and close the current WWTP.  This will include filling retention basins and installing sewer pipe to allow storm water to discharge to Stoney Creek.  

-- START contractors will collect surface water samples from the site drainage system in order to confirm effectiveness of surface decontamination.

Disposal activities include disposal from individual tanks, tank consolidations, and a variety of drums.  Single manifests may include wastes from multiple sources.  Wastes are primarily disposed as corrosive (acids and caustics), flammable (items containing solvents), and non hazardous (primarily oil-based materials).
