B. Direct Burn Areas Clean Harbors Deer Park facility processes many bulk waste streams by feeding directly to an incinerator system. In many instances, this is the safest and most environmentally responsible method for processing incompatible or reactive wastes. These materials are not transferred from their original trailers or container, or blended with any other waste materials. There are three separate direct burn areas to service the facility's incinerator systems. These areas are identified as: • Rotary Reactor Direct Burn Area • 4.4 Meter Kiln Direct Burn Area • Afterburner/Loddby Direct Burn Area - (The Afterburner/Loddby Direct Burn Area is divided into two parts: the Scale Section and the 29 Pad Section). The combined capacity of the Direct Burn Areas is eight 5,500-gallon trucks (44,000 gallons). Each of the areas is located on a paved area that has curbing or sloped drainage to provide for the containment of spills and/or contaminated rainwater. To control emissions, trailers processed at the Direct Burn Areas are connected to a dedicated vent system that feeds directly to the incinerator systems. C. Container QC Area The Container QC area is located due west of DSP-3 and DSP-6. It is a long, narrow area that is used for sampling and storage of containers that have not achieved Waste Analysis Plan discharge from the laboratory. Upon achievement of laboratory discharge, within 24 hours the containers in this area are moved to other permitted storage or processing units. Maximum storage capacity for the units is 75,000 gallons. The unit has secondary containment that meets the requirements of a Container Storage Area. D. Continuous Mixer (Pugmill B-1203) The Continuous Mixer (Pugmill B-1203) is an intensively agitated mixer installed and used in the waste Stabilization and Encapsulation (S&E) process prior to landfill. The pugmill receives screened or shredded waste, stabilizing agents, water and slurries. In the pugmill, the materials are thoroughly mixed and discharged to the T-1204 pit for storage prior to disposal in the landfill. The pugmill is electrically powered and has a capacity of 22 cubic yards. No ignitable, reactive, or incompatible wastes are processed in the pugmill. The mixing operation is controlled by process computer and is monitored by on-site operators to prevent overfilling and to ensure the design operational efficiency. 26
The pugmill is completely enclosed inside the S & E building, which provides containment and protection from direct precipitation and run-on. The building ventilation and baghouse filter system also provides dust emission control for the pugmill. E. Rotary Reactor Feed System The Rotary Reactor Feed System consists of the Rotary Reactor Feed Tank (T-638), Rotary Reactor Shredder and the Rotary Reactor Feed Building. The Rotary Reactor Feed Tank is used to store bulk solids for feed to the Rotary Reactor Kiln and the Rotary Reactor Feed Building houses the clamshell bucket that conveys the waste T-638 to the Rotary Reactor Kiln. Tank T- 638 is 12 feet x 9 feet x 9.5 feet with a total capacity of 37.5 cubic yards. The feed building is 20,900 cubic feet in volume. The Rotary Reactor Feed Tank is an open-topped, double-walled, below-grade steel tank that is completely enclosed below grade in a concrete vessel with a leak detection sump. The doublewalled construction provides an adequate secondary containment system. The Rotary Reactor Feed Tank is filled from bin trucks or a front-end loader with an operator in attendance. This ensures that the tank will not be over-filled. Material placed into this tank is promptly moved to the Rotary Reactor Shredder via the clamshell bucket system. The feed material contains no free liquids, and incompatible materials are not fed to this tank. If ignitable wastes are added to this unit, procedures for ignitable tanks waste are followed. The Rotary Reactor Feed Tank and the clamshell bucket are completely enclosed in the Rotary Reactor Feed Building. The building has a dedicated vent system that feeds to the incinerators to control emissions. The building also protects the feed system from direct precipitation, run-on and wind action. The Rotary Reactor Feed Tank (Tank T-638) is inspected, tested and certified for hazardous waste service as part of the facility’s annual waste tank integrity inspection. F. PCB Shredder The PCB Shredder is a device that is used to shred containers of PCB-contaminated materials. It is often necessary to cut up some PCB-contaminated containers and materials to a size and form that is more effectively incinerated. These materials are fed into the PCB Shredder. Some PCB materials could be contaminated with RCRA regulated wastes, so the PCB Shredder could handle both TSCA and RCRA-regulated wastes. The PCB Shredder sets on an irregularly shaped concrete pad that is located in a building common with the PCB Warehouse (Permit Unit No. 776.h). The irregular pad is 3,845 square feet in area. Most of the PCB Shredder is feed and discharge equipment. Emissions are routed to carbon beds. 27
