Initial excavation work was begun August 26, 1957 and completed on April 20, 1958, total final volume — 324,300 CY. First structural concrete in the area was poured on January 21, 1958, and final area concrete was placed on May 23, 1959, total volume — 26,960 neat line CY. Initial structural steel for the Power House was erected in May 1958, and final area steel was erected in early August 1958, total quantity in place — 6,800 tons. Design and construction supervision for the two refractory brick lined, concrete stacks was furnished by Rust Engineering Company of Pittsburg, with the Contractor supplying all required labor. The first converter stack lift was poured on June 20, 1958 and was topped, out at a height of 358'-9" on September 24, 1958. The first lift on the reverberatory stack was poured. October 9, 1958 and topped out December 16, 1958 at a height of 342'-0". The first turbogenerator was placed in operation on June 29, the second unit following in mid-August 1959. Charging of the first reverberatory furnace was begun on November 14, 1959, and the initial furnace tap was made November 19, 1959. The Power Plant consists of two 22,000 KW Brown-Boveri hydrogen- cooled, condensing strain turbine generators operating at 850 psig and 900° F. and generating 13,800 volt, 60 cycle, 3 phase current. Primary steam source is a pair of Babcock and Wilcox direct fired boilers, each with a continuous rated capacity of 215,000 lbs. of steam per hour at 850 psig and 900° F. Supplemental steam is furnished by four Babcock and Wilcox waste heat boilers, each using 117,000 lbs. of reverberatory furnace waste gas per hour at 2300° F. to produce 4,000 lbs. of steam per hour at same specification as the main power boilers, fuel for which is Bunker "C" oil. Circulating sea water for condenser cooling is supplied by three Bingham vertical turbine pumps, each rated at 23,000 G?M against a 65" head differential. The diarvtor concrete pipe supply and return circulating water lines was manufactured under supplement to
