In the two substations feeding the line, SCE&G has automatic breaker reclosing systems that are used if a problem occurs on the line. The 370 meter feeder line runs to Block C10 where one main transformer (115 KV/13.8 KV, 28 MVA) with a circuit switch is located. The feeder, transformer and circuit switch are owned by SCE&G. CRP distributes 13.8 KV from the main load center to site customers or to power transformers lowering the voltage to 480V or 2400V. Steam Saturated steam is generated in three package boilers with a total installed capacity of 140,600 kg/hr and a practical capacity of 81,650 kg/hr. Boiler #3 is capable of firing natural gas or No. 2 fuel oil, and is considered the primary boiler. Boilers No. 1 and No. 2, capable of firing natural gas and No. 6 fuel oil are considered back-up boilers. Compressed Air The instrument and plant air systems consists of various components and piping distribution to deliver air services to the different manufacturing and service areas at the Site. The system has eight air compressors with their associated filters and coolers, five air dryers, one volume tank, a priority valve system, and the distribution piping. Currently, the site plant air requirements are supplied from the eight air compressors with a total capacity of 19,539 m 3 /hour.

2 Process Water The Site Process Water System consists of a river pumping station, a treatment plant, an elevated water tower, and the distribution piping. The system consists of many components to pump, treat and distribute process water to customers throughout the Site. The system is comprised of many components including pumps, analyzers, pressure/flow transmitters, VFD s, level switches, valves, motor starters, and flow meters. Currently, the site plant water system is made up of parallel clarifier and filter trains with a total capacity of 16,353 m 3 /day. Recycled non-contact cooling water supplements the system with an additional 4,906 m 3 /day. Potable Water The Berkeley County Water & Sanitation Authority is the supplier of potable water to the Bushy Park Plant. The Site Potable Water System consists of only the piping to distribute the Berkeley County potable water to the site s various customers for drinking and other domestic use. The most significant usage is for safety showers and sprinkler systems. Nitrogen Currently, the site nitrogen gas requirements are supplied by a cryogenic system owned, operated and maintained by Praxair. The system includes bulk liquid nitrogen storage tanks with atmospheric / steam evaporators that provide nitrogen gas sufficient to meet plant demand during power outages and maintenance. CRP distributes the nitrogen gas to the site customers. Refrigeration The Bushy Park Site refrigeration system supplies ammonia to various heat exchangers in the manufacturing areas. The system consists of three compressors ( bar suction pressure each), four evaporators, a cooling thermosyphon, a main receiver, a flash economizer, a recirculator vessel, supply pumps, a pumpout system, and the associated instrumentation. The liquid ammonia is delivered to the various heat exchangers located throughout the site.

The Firewater System components consist of two dedicated fire water pumps, a jockey pump system, the fire water distribution piping grid, an elevated water tower, and a backup cross connection with the process water system. The procedures for emergency response and operation are detailed in various plant procedure manuals. SYSTEM OPERATION: During day to day operations, the fire water system is fully pressurized to a pressure range of 6.2 bar to 7.5 bar. The pressure is maintained by the jockey pump. In the event of firewater flow, the line pressure will drop and the fire diesels will cycle on at 5.86 bar for fire diesel #1 and 5.17 bar for fire diesel #2. If fire water pressure drops to 5.5 bar, the inlet altitude valve to the elevated tower closes allowing for any of three process water pumps to be completely diverted to the firewater cross-connection. If firewater pressure drops below 4.48 bar the #1 process water pump will start. The process water to firewater cross connection is protected with back flow preventers to ensure fire water supply. The firewater system has an additional reserve in the elevated tower due to the stand pipe arrangement internal to the tower which sets aside 568 cubic meters of water in a direct connection to the fire water system at a pressure range of 3.86 to 4.27 bar, depending on tower water level. The firewater is distributed through a predominately 25 cm piping grid system and is fed through a 442 meters length of 30.5 cm underground piping from the River Pump Station to the main plant area. Fire diesel #1 capacity: m bar

One of the three pumps has a dual drive with a primary electric motor and a diesel engine backup. Wastewater Treatment - Tower Biology -- Design Specifics The Tower Biology system is an above-ground aerobic, activated sludge treatment system consisting of equalization, neutralization, primary treatment, biological treatment, and sludge dewatering. The sustainable capacity is 14,969 kg/day BOD5. The Tower Biology System consists of three equalization tanks (7,571 cubic meters total), one buffer tank (910 cubic meters), two neutralization tanks (61 cubic meters each), two primary clarifiers (946 cubic meters each), two biological towers (7,571 cubic meters each), two secondary clarifiers (1,893 cubic meters each), one sludge conditioner (946 cubic meters), and one plate & frame filter press. The system is designed with a significant amount of flexibility in dealing with spills and abnormal events. Spills can be routed to the buffer tank or one of the three equalization tanks. It is not necessary for tenants to install additional equalization equipment to deal with abnormal events. Pretreatment is not required. Stormwater Management The Bushy Park Industrial Complex has an elaborate storm water collection system located within basically two drainage areas. Each of the drainage areas has an associated holding pond and outfall.
