B -- PILOT-SCALE EVALUATION OF SCR IMPACTS ON MERCURY VAPOR SPECIATION SOL CFX218 DUE 082800 POC Barbara Curtiss at 513-487-2036 or Fax to 513-487-2109 E-MAIL: U.S. EPA, CINCINNATI CONTRACTS MANAGEMENT DIVISION, curtiss.barbara@epamail.epa.gov. The U.S. Environmental Protection Agency (US EPA) intends to negotiate on a Sole Source basis, without full and open competion, under the Authority of 41 U.S.C. 253(c)(1) and pursuant to FAR 6.301-2, with University of North Dakata. The required efforts are highly specialized, involving use of a coal combustion pilot facitily with selective catalytic reduction (SCR) and electrostatic precipitation (ESP) technologies installed for flue gas cleanup. In addition, measurements of very low concentrations of mercury vapor in flue as with ammonia vapor are required. The contractor is required to have an operating pilot facility, a recent history of successful research in mercury vapor measurements and ammonia-mercury interaction having established experimental equipment and procedures also to ensure performance with minimal start-up time delay. The analysis will help the EPA to learn the behavior of mercury vapor in the presence of ammonia and catalysts and develop strategies for concurrent mercury vapor and NOx control, manage solid byproducts and wastes safely, and assist in interpreting existing field data where ammonia-based NOx controls are practiced. The contractor shall test for mercury species by Ontario Hydro method, ammonia, and HCI (EPA Method 26) at four loctions (1) prior to the SCR unit, (2) following the SCR Unit, (3) at the ESP inlet, and (4) at the ESP outlet on a pilot coal combustor with SCR and ESP controls, firing a typical midwestern coal. A total of three separate tests shall be made and the results presented as individual data points and as a three-test average. The contractor shall collect three coal samples and three ESP hopper samples during the test and analyze each for chlorides and mercury. In addition, the ESP hopper sample shall be tested for ammonia. The contractor shall prepare a draft final report and deliver the EPA Project Officer with 30 days of completion of tests. A final report shall be delivered to the EPA Project Officer 60 days of test completion. THIS IS NOT A REQUEST FOR PROPOSAL. SOURCES WISHING TO BE CONSIDERED MUST SUBMIT DOCUMENTATION TO THE OFFICE IDENTIFIED ABOVE. Documentation must be submitted within 15 days of the date of publication of this notice. Submit your request in writing. NO TELEPHONE REQUEST WILL BE HONORED. Submit your request to Barbara Curtiss, telephone 513-487-2036 or fax to 513-487-2109. Posted 08/14/00 (W-SN485821). (0227)
