E-MAIL: U.S. EPA -- Cincinnati Contracts Management Division, roe.kathleen@epamail.epa.gov. The U.S. EPA National Risk Management Research Laboratory, Air Pollution Prevention and Control Division, plans to negotiate on a sole source basis with TSI Incorporated for the procurement of a Scanning Mobility Particle Sizer, a particle measurement system for use in the determination of provenance for combustion-generated fine particulate and on-going diesel emissions study. The instrument shall use the principle of differential mobility and condensation particle counting in the range of 0.01 to 1.0 m. It shall include an electrostatic classifier, condensation particle counter, firmware & fast-scanning software, vacuum pump, and interconnecting hardware. EPA source research indicates that TSI, Inc. is the only responsible source capable of providing such an instrument. However, any firm believing itself capable of meeting the requirements may submit technical documentation to demonstrate its potential of doing so. Otherwise, EPA will proceed to negotiate with TSI. The proposed purchase order is for supplies for which the Government intends to solicit and negotiate with only one source under the authority of FAR 6.302. This notice of intent is not a request for quotations. An RFQ will not be issued, however, all quotations received within 15 days after the date of this synopsis will be considered by the Government. A determination not to compete this requirement based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. Posted 08/19/98 (W-SN239204). (0231)
