A -- PARTICULATE MATTER MEASUREMENT (PM) TECHNIQUES AND ERRORS AND PM COMPOSITION SOL PR-98-00542 POC Billy Oden, Contracting Officer, (513) 487-2126 E-MAIL: U.S. EPA -- CINCINNATI CONTRACTS MANAGEMENT DIVISION, oden.billy@epamail.epa.gov. U.S. Environmental Protection Agency -- National Center for Environmental Assessment has the responsibility under the Clean Air Act for preparing a document describing the scientific criteria for National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM). The NAAQS for PM will become part of the next PM Air Quality Criteria Document (AQCD). This review of the scientific basis for PM is being conducted in several phases. For purposes of the current phase USEPA is seeking to retain the professional services of a scientist with knowledge of PM measurement techniques and errors and of PM composition. USEPA intends to issue Request For Quotations (RFQ) to sources that have been qualified as capable of performing professional services in support of the Agency's effort to prepare a document describing the scientific basis for review and possible revision of the current National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM). These previously qualified sources were identified through responses to USEPA's Commerce Business Daily (CBD) announcement of 02/20/98, which expressed that the Agency was seeking potential sources possessing scientific backgrounds and extensive knowledge of particulate matter with the capability to provide USEPA with high quality assessment of the latest available scientific information to be used in support of the next PM NAAQS review. Previously qualified sources were evaluated based on submission of: curriculum vitae, publication history and other written materials that described scientific expertise, and evidence of previous contributions to similar assessments. Interested parties not previously qualified will be required to submit similar materials to establish qualifications with their proposals. The required services will involve the completion of several tasks, which could involve: (1) authorship of one or more technical draft sections on PM measurement techniques and errors and PM composition for the revised PM Air Quality Criteria Document (AQCD); (2) participation in scientific peer-review meetings / conferences (travel will be required); (3) attend Clean Air Scientific Advisory Committee (CASAC) Review Meeting and assist in the revision of the draft PM ACQD in response to CASAC review and public comments; and (4) assist in developing responses to comments received from the public and from the Clean Air Scientific Advisory Committee of EPA's Science Advisory Board. A detailed Statement of Work will be issued with the RFQ. Requests for Quotations will be issued to previously qualified sources on or about 06/17/98, providing for a response time of a maximum of 14 days. EPA intends to issue a firm-fixed price purchase order, with a cost reimbursable line item for Travel. Issuance of a purchase order will be based on technical qualifications and low price. Interested parties who did not respond to the 02/20/98 CBD announcement should request a copy of the RFQ by sending an e-mail to Billy J. Oden, Contracting Officer, at the e-mail address provided with this announcement. Requestors should include a complete mailing address with their requests. (SEE Note 1) (0153)
