B -- DEVELOPMENT OF PROTOCOL FOR COMPARISON AND ANALYSIS OF CHEMICAL MECHANISM PERFORMANCE SOL RFQ-99-U2B102 DUE 091199 POC Starry M. Jones, Contract Administrator, (919)541-2897; Julio Lopez, Contracting Officer (919)541-4474 E-MAIL: ERROR --, jones.starry@epa.gov. The U. S. Environmental Protection Agency (EPA) intends to negotiate a sole source procurement to Dr. Gail Tonnesen, University of California, Riverside, Riverside, CA 92521, for the Development of Protocol for Comparison and Analysis of Chemical Mechanism Performance. Dr. Tonnesen developed and wrote the Process Analysis and Integrated Reaction Rate software and has applied it for numerous types of simulations, and authored many journal articles on the subject. The purpose of this contract is to develop a protocol of a recommended, standard set of tests that can be used to analyze the performance of a chemical mechanism and to compare two or more mechanisms. The methodology shall be demonstrated by performing an in-depth comparison of 3 current chemical mechanisms. A secondary objective of the project is to provide interpretation of the test results, and use them to consult with EPA on how they provide guidance for the selection of chemical mechanisms to be used in EPA's regulatory models. Contractor requirements are: 1) Develop protocol and make software modifications to perform the tests and analyze the results. Recommend a set of tests that should be performed to do a thorough examination; 2) Demonstrate the protocol through an intercomparison of three chemical mechanisms; 3) Consult with EPA on interpretation of selected test results, recommendations for EPA regulatory models, and implications for verifying the accuracy of the mechanisms and 4) Document the protocol in a final report and deliver all software and computer files to the Environmental Protection Agency. All interested parties who believe they can provide the required services should fully explain their capabilities in writing within 15 days of the date of this announcement. No Solicitation is available. The intent of this synopsis is to determine if any sources(s)exist and, therefore, no RFP is available. Consequently, any response(s) failing to provide the aforementioned data but instead choosing to merely submit a routine letter requesting a copy of the RFP will be ignored. Submit response to the U.S. EPA, Attn: Starry M. Jones (MD-33), Contracts Management Division, Research Triangle Park, NC 27711. No telephonic or faxed request will be honored.
