Of the four construction firms invited to bid on erection of the BSC, one declined.
Another qualified firm was found and the bidding period was extended to allow time to
formulate their bid.
Lauren Engineers and Constructors was consequently selected to erect the BSC and
approval by DOE was sought. CTC started negotiations with Lauren in anticipation of
the start of construction. Award of the contract awaits formal approval by DOE.
Bids were sought from several firms to wire the BSC building. Clark Electrical
Contractors was selected and DOE approval was sought. Award of the contract
awaits formal approval by DOE.
There is a delay in obtaining approval of the construction and electrical contractors, or
more precisely to start construction of the BSC. The problem is linked to two issues.
First, the new building is viewed as a capital improvement of CTC property, which
could require special approval if funded by project money. Secondly, NEPA
implications must be reconsidered because plans to build the BSC process building
conflict with the FONSI statement, which indicates that the circuitry would be housed
within an existing structure.
Award of a patent for the calcium nitrate/decanter centrifuge coal cleaning process is
not likely. A pre-examination search of the patent literature disclosed that AMAX was
awarded patents for fine coal cleaning in 1985 and true heavy liquid media coal
cleaning in 1988. The patent, "Method For Cleaning Fine Coal," #4,529,506 describes
the use of a decanter centrifuge, and that organic or aqueous solutions of metal salts
could be used as parting fluids. There were other examples as well.
In response to the above concerns CTC prepared and submitted via letter the
rationale for moving the BSC from within the confines of an existing building to a free
standing and separate structure.
Here’s what’s next.
