- Description
- The National Institute for Occupational Safety and Health, ALOSH, Morgantown, WV requires professional expertise and services to test a surfactant-based sampler for ultra fine particle bioassay using dynameter-controlled diesel engine exhaust. The contractor shall provide test facilities and have primary responsibility for the performance of a field test of the physical performance of the device on the exhaust steam from a heavy-duty vehicle diesel operated on a chassis dynamometer under controlled laboratory test conditions. The contractor shall provide the necessary facilities for the test including the vehicle engine, dynamometer test bed, exhaust dilution system of the exhaust stream as performed for emissions testing, sampling and particle size distribution analysis systems for the diluted exhaust stream; and integration of the conditioned and characterized exhaust stream with the surfactant sample. The sampler will include use of a humidification pre-conditioner separately provided, to permit efficient impinger collection of hydrated nano-particulate material in the exhaust stream with subsequent capture of so-conditioned DPM into an impinger containing surrogate lung surfactant as the collection medium. The contractor shall perform the test of the surfactant sampler, measuring the mass efficiency of the sampler collection for fine and ultra fine particle size ranges. The surfactant sampler device is designed to preserve exhaust particulate nano-scale properties so as to permit short-term bioassays to address factors what may affect DPM genotoxic activity, e.g., associated with nano-aerosol fogs possibly generated by new Nox and PM controls for diesel exhaust. Such surfactant-mediated sampling under conditions modeling DPM deposition in the deep lung is to permit subsequent physiologically meaningful toxicological bioassays of collected materials that can be obtained in the short-term but that are suitable for guiding longer-term animal inhalation studies and for detailing specific engine and control system design and operational factors affecting exhaust DPM toxicity. The government intends to negotiate with West Virginia University as the only responsible source that will satisfy agency requirements. Dr. Mridul Gautam has unique knowledge and experience with the device having co-designed it and having participated in a field feasibility study of the operation of the device. He directs the Mobile Engine Emissions Test Laboratory of West Virginia University and makes available their mobile diesel engine dynamometer test stand and exhaust emissions sampling and characterization facility. No solicitation is available; however, interested parties may request a copy of the Statement of Work including deliverables. Responsible sources that believe they possess the expertise and capabilities identified above are encouraged to submit to the Contracting Officer within 15 days from the posting date of this notice their capabilities statement and supporting information in the format they choose, not to exceed 10 pages. Please forward capabilities and supporting information to: Rebecca Mullenax, Reference: # 000HCC34-2006-34280, DHHS, PHS, CDC, NIOSH, ALOSH, 1095 Willowdale Road, Morgantown, WV 26505 or RMULLENAX@CDC.GOV or fax to 304-285-6083. The government will review any/all capabilities statements and supporting information submitted and determine if other qualified sources do exist that could perform the effort. Information received in response to this notice will be used solely for the purpose of determining whether to conduct a competitive procurement. If no affirmative responses are received within 15 days, negotiations will be conducted with West Virginia University Research Corporation as the only source and a purchase order will be order will be issued without any additional notices being posted.
