The methodology applied for selecting technologies to be included in the FY93 Technology Catalogue began with a list of approximately 30 technologies developed by EM-52 in October 1992. Approximately 17 of the 30 technologies are featured in the FY93 Technology Catalogue. The methodology for selection of the remaining technologies featured in the FY93 Technology Catalogue began with a review of the ProTech Prospective Database technology profiles. ProTech developed by Battelle Pacific Northwest Laboratory for DOE is a prototype electronic system that describes innovative technologies of the IDs and was developed for use by the general public. The review was performed to determine which profiles were on the original list developed by EM-52. Those selected were mature (available currently or within the next 2-3 years) and contained sufficient technical detail (performance, cost, etc.). Of approximately 100 technology profiles reviewed, 34 were selected for inclusion in the FY93 Technology Catalogue.
The methodology utilized to prepare the technology entries is illustrated in Figure 1. While the primary source of information and data featured in the Technology Catalogue was ProTech, a number of other sources were utilized. Some of these sources include technical task plans (TTPs), conference proceedings, technical journals, environmental permit applications, and readily available technical documentation.

Once sufficient information was gathered, it was reviewed for clarity, consistency, and quality of technical information. The entry was then technically edited and revised. All entries were then consolidated into the FY93 Technology Catalogue for publication and distribution.
