The Space Shuttle Program (STS) at Vandenberg Air Force Base is expected to generate a variety of hazardous wastes during its years of operation, from 1985 through 1994. The purpose of this study was to compile a projected inventory of the types and quantities of hazardous waste likely to be generated by shuttle-related ground operations. This inventory will be used to assess waste management options, to complete EPA hazardous waste forms, and for preparing the supplement to the environmental Impact Statement. The inventory lists waste types; chemical constituents; baseline and contingency mass and volume per launch, for each year of the project, and per month for each year; EPA and California hazardous waste numbers and hazardous properties; and California compatibility class. Total baseline waste generation for the STS project is anticipated to be 130 million Kg. The greatest quantities of wastes are expected to be generated by Station Sets V23 and V32 (72 million kg and 54 million kg, respectively). Estimated total project waste generated under contingency conditions is 1.4 million kg. The only station sets identified as potential generators of contingency wastes are V19, V21, and V23. Station Set V23 is expected to generate approximately 84 percent by weight of all contingency wastes.
