D--Improvements to the UNMIX 2.3 Receptor Model

NAICS Code: 541512 The U.S. Environmental Protection Agency (EPA) intends to negotiate a sole source procurement on or about May 3, 2002 with Dr. Ronald C. Henry, University of Southern California, Los Angeles, CA 90089 for providing improvements to EPA's Unmix 2.3 Receptor Model. The period of performance shall be within nine months from date of award. EPA believes that Dr. Henry is the only source capable of providing the required services because the Unmix Receptor Modeling Tool software package is proprietary and was developed and copyrighted by Dr. Henry. FAR 6.302-1, "Only one responsible source and no other supplies or services will satisfy agency requirements" permits other than full and open competition. The intent of this notice is to determine if any other source(s) exist, and therefore, no solicitation (Request for Quotations) is available. All interested parties who believe they can provide the required services may respond by submitting a written narrative statement of capability for consideration by the agency within 15 days of this notice to: U.S. EPA, Attn: Barbara Nelson (E105-02), RTP Procurement Operations Division, Research Triangle Park, NC 27711. No telephonic requests will be honored. Response must include detailed technical information and other technical literature demonstrating the ability to satisfy this requirement. Responses shall also include itemized pricing that is sufficient to make a determination that competition is feasible. If no affirmative responses are received within 15 days of this notice to determine that competition is feasible, a purchase order will be placed with Dr. Henry.
