Place of performance is Fort Hunter Liggett, California. The aerator assembly is specified to precise mechanical and material standards: a 14.5–15.5 horsepower, three-phase, 60-cycle motor with 42/21 full-load amperage at 230/460 volts; a 17-4 precipitation-hardened stainless steel shaft, 1.625 inches O.D. and 28 inches long, with 135K–250K PSI yield strength; a 316 stainless steel propeller dynamically balanced to less than MIL maximum; and a 304 stainless steel or HDG steel deflector with chemical-resistant gel-coat UV finish. The aerator float is constructed by hand lay-up from CDM2415 PROMAT with chemical-resistant UV-stabilized gel-coat, 88 inches in diameter and 14 inches thick, with 3/8-inch internal reinforcing steel rings and 2-pound-density polyurethane closed-cell foam fill (minimum 0.25-inch thickness in non-stress areas). The complete unit weighs approximately 1,700 pounds and must deliver 12,172 gallons per minute at a 3.0 pounds per horsepower per hour oxygen transfer rate, with a minimum oxygen dispersion diameter of 210 feet at 6 feet depth.
