Johnson, Contract Specialist (9190 541-0952 or Julio Lopez, Contracting Officer, (919) 541-4474 E-MAIL: Click here to contact the contract specialist via, johnson.marsha@epa.gov. The U.S. Environmental Protection Agency intends to negotiate a sole source simplified acquisition with Pathology Associates International, 15 Worman's Mill Ct., Frederick, MD 21701 to complete the histotechnology and pathological analysis of the EPA Study 9603-DCA Drinking Water Exposure in Mouse. The Contractor shall process wet tissues and blocks to H&E slides and conduct pathological evaluation of all tissues in the EPA 9603-DCA Drinking Water Exposure in Mouse study. The EPA study 9603 is a 2 year carcinogenicity study of DCA in the female F344 rat which completes the DCA bioassays in male and female rats and mice. It is anticipated that the period of performance will be from date of award through three months. The proposed purchase order action is for services for which the Government intends to solicit and negotiate with only one source under the authority of FAR 6.302. Study 9603-DCA was started by Pathology Associates International under a previous contract which expired prior to the study's conclusion. Under said contract, Pathology Associates International has already conducted the pathologic analysis of tissues taken at 52 weeks into the study. EPA believes that Pathology Associates International is the only alternative source which would be able to complete this effort without without jeopardizing the study's validity and avoid the time delays and duplication of costs associated with starting the study again. No solicitation is available. This notice of intent is not a request for competitive proposals. All interested parties must identify their interest and capability to respond to the requirement within 15 days of the date of this announcement. A determination by the Government not to compete with this proposed purchase order based upon responses to this notice is solely within the discretion of the Government. Telephone or fax requests will not be honored. Submit response to the U.S. EPA, Attn: Marsha B. Johnson, (MD-33), Contracts Management Division, Research Triangle Park, NC 27711.
