B -- FIELD AND OVERHEAD SPECTRAL DATA COLLECTION SOL UUA791 POC Karen Z. Gibson, Contracting Officer, (919)541-4556 E-MAIL: Click here to contact the Contracting Officer via, gibson.karen@epamail.epa.gov. THIS IS AN AMENDMENT TO A SYNOPSIS PREVIOUSLY PUBLISHED ON 1/20/99. THE ANNOUNCMENT IS REVISED TO READ AS FOLLOWS: The U.S. Environmental Protection Agency intends to negotiate on a sole source basis with Virginia Institute of Marine Science, Gloucester Point, VA 23062 for Digital Multi-Spectral Video (DMSV) Imagery and Field Spectra of 15 contaminated mine drainage sites in the Southern Anthracite Coal Field, Pennsylvania area. The specific research objectives are 1) to correlate aerial spectral-reflectance imaging data with ground spectral-reflectance data to verify that the images observed from the air are comparable to those recorded from the ground; 2) to quantify the relation between key water-quality measures and both ground-collected and aerially-collected spectral-reflectance data and; 3) to explain the sources of variability by analyzing microbial populations and the mineralogy and chemistry of streambed precipitates. The Contractor shall provide DMSV data and ground spectra for the sites which will be located in the area of abandoned deep-shaft mines, once each season for a total of four times during the period of performance. The Contractor shall collect data from ground and aerially mounted DMSV imagers. Water-quality and streambed precipitate samples shall be collected concurrently with the spectral data. The Contractor shall also process and analyze the remote sensing and field spectra data and draft a project report of the significant findings. EPA believes that Virginia Institute of Marine Science is the only vendor capable of satisfying the requirements stated above. Virginia Institute of Marine Science has extensive prior research in remote sensing of contaminated mine drainage in the area. Virginia Institute of Marine Science has conducted preliminary testing of ground-based microbial and spectral reflectance techniques and demonstrated the potential for differentiating between acidic and near-neutral drainages. The period of performance is expected to be from the date of award through June 30, 2000. No solicitation is available. All interested parties must respond within 15 days of the date of this announcement. Interested vendors shall submit a capability statement that demonstrates knowledge and experience of abandoned deep-shaft mines in the Eastern United States Coal Mining region, familiarity with DMSV, in collecting ground spectra, and remote sensing and processing of the complex spectral response of contaminated mine drainage. The capability statement should demonstrate the vendors ability to perform the work described above. Responses should be submitted to the U.S. EPA, Attn: Karen Z. Gibson (MD-33), Contracts Management Division, Research Triangle Park, NC 27711. No telephonic requests will be honored. See numbered Note 22. Posted 01/29/99 (W-SN293016). (0029)
