Intiial funding requireaent for the field <br />investigations identitied as A and B above is $448,280; these studies <br />aust be coapleted before June, 1987. In addi tion, about $381,965 <br />will be needed tor the remaining field investigations (C through E <br />above); these must be coapleted prior to initiating final design <br />preparation for coaaercial facilities. <br /> <br />Additional Engineering Investigations <br /> <br />Twenty-four additional engineering tasks are listed and brietly <br />described at the end of Chapter 3. At least 11 of these tasks should <br />be completed betore construction ot the STEP pilot plant begins. <br />While DEC believes that all 24 engineering tasks should be completed <br />before initiation of STEP pilot plant construction, it is possible <br />that the last 13 of these tasks could be deferred teaporarily. <br /> <br />Rather than <br />together into <br />priority: <br /> <br />list all 24 tasks below, these tasks have been lumped <br />broad categories and these are given below in order of <br /> <br />A. Additional site investigation work to find better STEP sites <br />closer to the saline water source and select one site for design <br />(Tasks 2 and 3) $37,000 <br /> <br />B. Investigate and evaluate potential iaprovements in STEP process <br />design including use of sand and gravel as a growth mediua, <br />design philosophy, calciuim sulfate harvesting, spray evaporation <br />system, and the STEP crop production ponds (Tasks 4, 7. 8, 9, and <br />10) $62,000. <br /> <br />C.
