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.  

The OSC continues to estimate that the remaining chemical inventory within the tanks at the Site is approximately 200,000 gallons and consists primarily of lower viscosity materials and tank heels in about 100 tanks.

OSC Dominic Ventura is currently preparing to assume lead OSC responsibilities at the Stoney Creek Technologies Site.

The START contractor completed an evaluation of all tanks at the Site to determine material volume, consistency, and vapor issues in order to allow the OSC to scope and prioritize remaining response actions. With this data, the OSC had directed the ERRS contractor to consolidate compatible tank material for disposal.

EPA contractors have continued and still continue to break and drain lines, equipment and process vessels containing chemical inventory.  

The ERRS contractor diulted the remaining oleum sludge located in T-105 with material (low strenght acid from the vapor system) from T-120. The material was pumped into the tank and circulated to promote mixture and dilution of any oleum remaining in the sludge.  After the mixture was pumped from the tank into drums, additional acid was pumped into tank, the manway was opened, and the material was handmixed. All material was then pushed to the rear of the tank and drained from the lowest available valve.  The tank was inspected and determined to only contain residual coating upon the interior steel.  The tank was re-secured until a final solution for the residual is determined.

Additional leaks were discovered at the Site including a leaking flange at the D-104 sulfonator.  About 30 gallons of acid was drained from this system.  Excessive heat is expected to blame for the increased number of leaks discovered in July and August.  ERRS removed chemical material from the sulfonator trench and found that the concrete trench system was completely dissolved by prior acid spills, exposing the underlying soils.

The OSC directed ERRS to drain the material from T-229; a thick resin material (Beckosol).  To date, 43 drums have been generated.
  
The transfer and disposal of all "white oil" contents occurred on August 16th, 2010.  This material had been saved in case of an oleum spill.

The OSC continues to coordinate with EPA Pre-Remedial personnel presently evaluating the Site for possible NPL listing.

Complete off-Site disposal of drummed wastes.  

Continue to clear pipelines of remaining chemical inventory, consolidate and prepare materials for disposal.

Continue consolidation of remaining tank heels or drumming of tank heels for disposal.

Continue to monitor, treat, and discharge excess waters from the Site into Stoney Creek and prevent oily material from migrating from the Site into Stoney Creek via discharges onto the adjacent public roadway.

rioritize remaining removal actions and coordinate with Pre-Remedial regarding possible NPL listing.

START contractor will implement site wide drainage characterization sampling to assist the OSC in determing water quality issues throughout the Site and develop a database for use in determining the level of decontamination required to assure good quality discharge from the Site to Stoney Creek. .

START contractor will implement site wide subsurface soil sampling with the use of a Geoprobe in order to visually confirm areas of subsurface contamination contributing to the surface release of oily materials to Stoney Creek.  This effort will also include evaluation of contamination in the rail ballast along the industrial sidings serving the Site.

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).
