- Description
- NAICS Code: 541990 The U. S. Environmental Protection Agency (EPA) intends to negotiate on a sole source basis with University of East Anglia, Norwich NR47TJ, U.K., to participate in the task of developing a PM chemistry model that will be used by EPA and the States to evaluate control strategies for reducing ambient PM2.5 concentrations in support of the Office of Air Quality Planning and Standards (OAQPS), Research Triangle Park (RTP), NC. EPA is interested in the development of such a model that will enable the agency to determine the contributions of specific sources to ambient PM2.5 levels. Recently, Dr. Simon Clegg of the University of East Anglia, an internationally recognized expert in PM chemistry modeling, with support from Dr Edward Edney of the National Exposure Research Laboratory (NERL) RTP, has developed the first version of a new PM chemistry model, the Aerosol Inorganic and Organic Model (AIOM), for predicting ambient compositions of PM2.5 containing organic compounds, inorganic salts and acids, and liquid water. The general barriers within the scientific community have been that (1) the individual physical and, in particular, chemical processes, especially those involving organic-water, organic-organic, and inorganic-organic interactions have not yet been sufficiently established to develop such a model and (2) even if somehow it was possible to develop the model, the required thermodynamic input data are largely unavailable, especially liquid vapor pressures and activity coefficients of polar organic compounds that make up a significant portion of the PM2.5 mass. The reasons that EPA believes that the University of East Anglia is the only source capable of providing the specific services is due to the fact that during the past year, Dr. Clegg (of the University) and Dr. Edney (of EPA) have been able to overcome these road blocks by (1) expanding the Aerosol Inorganic Model (AIM), developed by Dr Clegg over the past 8 years and has been regarded as the most rigorous inorganic model in the world, to include organic compounds using a novel approach reported in the journal article authored by Clegg et al.,2001, Thermodynamic Modeling of Aqueous Aerosols containing Electrolytes and Dissolved Organic Compounds, Journal of Aerosol Science, 32, 713-738 and by (2) modifying the computational chemistry-based Conductor-like Screening Model (COSMO) so that it can be used to predict liquid vapor pressures and activity coefficients of organic compounds in PM2.5. Also, Dr. Clegg is the only known contractor having experience using the AIOM to predict concentrations of organic and inorganic compounds in PM2.5. Objective: It is anticipated that OAQPS along with the States will use a version of AIOM in state implementation plans to assess control strategies for reducing ambient PM2.5 concentrations. Scope of Work: The following tasks shall be performed as soon as possible to meet the Fiscal Year 2004 Annual Performance Measure (APM) 222 deadline of September 30, 2004. Task 1) Modify COSMO so it can be used to predict the liquid vapor pressures of organic compounds over a wide range of ambient temperatures and then evaluate the reliability of the predictions; Task 2) Complete evaluation of COSMO calculations for activity coefficients of water and organic compounds; Task 3) Modify AIOM to improve the treatment of interactions of organic compounds in PM2.5; and Task 4) Evaluate AIOM using laboratory data and available PM2.5 field measurements, including those collected at the EPA Speciation Supersites. In addition, the contractor shall provide advisory, assistance, and consultant services to NERL to modify and evaluate AIOM. Deliverables: Individual reports summarizing the results of completing each of Tasks 1, 2, 3, and 4 are required. The performance period is for twelve months. The place of performance is located in Research Triangle Park, NC. The North American Industry Classification System (NAICS) Code 541990, which has a small business size standard of $5.0 million, is applicable. 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 additional source (s) exist and, therefore, no Request for Proposal (RFP) is available. Consequently, any response (s) failing to provide the aforementioned data but instead choosing to merely submit a routine letter, calling or requesting a FAX copy of an RFP will be ignored. Submit your response no later than 6 March 2003 to U.S. Environmental Protection Agency, Attn: Joy Kimble, RTP-POD (E105-02), Research Triangle Park, NC 27711. You may FAX your response to (919)541-4273, or email your response to kimble.joy@epa.gov.
