The Radford Army Ammunition Plant (RFAAP) Acid Farm storage tanks are utilized for the containment of Spherical Nucleic Acid (SNA), Sulfosalicylic Acid (SSA), Oleum, Pyro, and Weak Nitric Acid (WNA), all of which are essential to Nitrocellulose (NC) production. The Acid Tank Area currently supports both the Nitric Acid Concentrator/Sulfuric Acid Concentrator (NAC/SAC) and the MNC production facility. The modernized NAC/SAC, presently undergoing upgrades, is designed to process approximately 100 million pounds of SNA (98.5 wt.%) annually, to meet the maximum production demand of 28 million pounds of NC per year. To achieve this, Architect-Engineering (A-E) design services are required for a modernized Acid Tank Area capable of supporting capacity requirements of the modernized Nitric Acid Concentrator/Sulfuric Acid Concentrator (NAC/SAC), Modernized Nitrocellulose (MNC) production facility, and the Modernized Nitroglycerin Production Facility (NG-3) at the Radford Army Ammunition Plant (RFAAP). The Tank Area shall be required to handle pyro acid, Strong Sulfuric Acid (SSA), Oleum, and Strong Nitric Acid (SNA). The Advanced (90%) Design shall include all required tanks and supporting infrastructure. The Design shall address all environmental and safety issues related to the receipt, storage, and dispersal of the various acids. Where technically and economically feasible the design will incorporate retrofitting and reuse of legacy structures, demolition of obsolete legacy equipment, and a phased modernize-in-place approach for the Tank Areas in highest need of upgrades or increased capacity.
