Corning Corporation Research! and Engineering Center 800 Presque Isle Drive Pittsburgh!, Pennsylvania 15239 April 21. 1969 Doctor Morton Corn 310 Bower Hill Road Pittsburgh, Pa. 15228 Dear Morton: Per our telephone conversation of April 17, 1969. present plans for UNIBESTOS scrap handling include retaining the Butler Building as a storage receptacle. A feasibility study is in process to determine problems and costs associated with mechanically transferring scrap from the Butler Building to the weigh hoppers above the feeders. Also, all dust collectors for the mixing area will be located at the south end of Plant 8 (present location of the Nor-Bio unit). Costs of preparing a site on the west side of Plant 8 appear to be too high in relation to the benefits gained. / Very truly yours. PITTSBURGH CORKING CORPORATION John L.
