70 -- PURCHASE AND DOCUMENTATION OF MAPPER SOFTWARE SOL DAC206 POC Kelley Holton, Contract Specialist, (919) 541-2125/ Jim Kempf, Contracting Officer, (919) 541-2125 E-MAIL: Click here to contact the Contract Specialist via e-mail., holton.kelley@epamail.epa.gov. The Environmental Protection Agency (EPA) intends to award a sole source purchase order to Envair of Albany, CA, pursuant to 41 U.S.C. 253(c)(1) -- Only one responsible source and no other supplies or services will satisfy agency requirements. This procurement is for the purchase of the MAPPER software along with a technical reference manual and a detailed users guide. EPA plans to make this software and documentation widely available to the regulatory and scientific community. Photochemical models are being used by air pollution regulatory agencies to determine the direction (VOC vs NOX) and magnitude of emission reductions required to meet the existing and proposed ozone NAAQS. While these models are technically sophisticated, the sensitivity of predicted ozone to changes in VOC and NOX emissions remains uncertain and subject to question. Because decisions based on these models have significant health and economic consequences, EPA is promoting the use of ambient-based empirical techniques that may be used to corroborate the direction of emission reductions suggested by photochemical models. MAPPER is one such tool that can be used to estimate day-to-day changes in ozone-NOX sensitivity using available ambient measurements of ozone and NOX species. Preliminary studies have shown that applications of MAPPER in non-attainment areas can significantly augment the information from photochemical models and enhance the credibility of proposed emission control measures. The contractor shall make modifications of the computer code based on comments received by the beta testing and from EPA reviewers of preliminary versions of MAPPER within 4 months after the effective date of the contract. This shall include the source and binary code for compilation and execution in a Microsoft Windows environment (Win 3.11 or Windows 95 OS). In addition, a sample data set shall be included for testing the execution of the MAPPER software package. The modified code shall be tested using sample ozone and NOX data sets and evaluated for accuracy in reproducing the underlying scientific principals embodied in the code. The contractor shall prepare a technical reference document that describes the scientific basis for MAPPER within 5 months after the effective date of the contract. The contractor shall deliver 2 hard copies and 1 electronic copy of the technical reference manual in WordPerfect 6.x format. The document shall also include a complete mathematical description of the algebraic relationships used to translate MAPPER input conditions to MAPPER output files and graphical displays. All assumptions, uncertainties and caveats associated the algorithms used in MAPPER shall be clearly stated. The contractor shall prepare a users guide for the MAPPER software describing in detail input data requirements, formats and options for handling missing data within 5 months after the effective date of the contract. The user guide shall also contain instructions for installing and testing the software. The contractor shall deliver 2 hard copies and 1 electronic copy of the user guide in WordPerfect 6.x format. The users guide shall also describe options for obtaining outputs, graphics and other information needed for interpreting results from MAPPER. Procedures shall also be included for testing MAPPER using a sample data set to be supplied along with the software. The contractor shall also provide a written statement giving EPA the express right to provide unlimited distribution of the software and documentation. All responsible sources may respond by submitting a written narrative statement of capability within 15 days of this notice to Kelley Holton at the above address which shall be considered by the Agency. Responses must include detailed technical information and other technical literature demonstrating the ability to meet the 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 whether a qualified source is more advantageous to the Government, an order will be placed with Envair.
