B -- ANALYSIS IN DIFFERENCES IN WEEKDAY AND WEEKEND LEVELS OF NOX AND VOCS AND THE RESULTING OZONE LEVELS USING PAMS DATA SOL DAC264 POC Tillie Newsome, Contract Specialist, (919) 541-3164 E-MAIL: Click here to contact the Contract Specialist via E-Mail., newsome.otelia@epa.gov. EPA intends to award a sole source purchase order to SAIC, 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 analyzing differences in variations in emissions of VOCs and NOx between weekdays and weekends. The project involves use of these differences as explanatory variables for resulting Ozone levels and discussion of policy implications of a "weekday/weekend effect." The proposed analysis shall utilize Photochemical Ambient Monitoring Stations (PAMS) data to provide an appraisal of the characteristics of the chemistry and temporal behavior of precursor emissions that produce Ozone. The study shall utilize data obtained from PAMS sites as well as other Ozone monitoring sites over several years and requires experience with the processing and analysis of Photochemical Ambient Monitoring Stations (PAMS) data. No Request for Quotation is available and this notice of intent is not a request for competitive quotations. All responsible sources may respond by submitting a written narrative statement of capability within 15 days of this notice to Tillie Newsome at the above address for consideration by the Agency. Responses must include detailed technical information and other technical literature demonstrating the ability to meet these requirements. 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 SAIC.
