The assumption that all batch dumps will be hazardous waste falls into this category.

These wastes include spent acid and alkaline with the Facility, it may be unrealistic to assume that these solutions, mixed metal sludges, and other heavy metal ? companies would send all of their batch dumps to the Facility solutions.

As described ' industries. There are 94 such firms in the metropolitan area above, this is probably unrealistic in terms of batch dump and 42 firms in the outstate area. Based upon MRC's original i1 quantities. Projected revenues from sludges, however, may be market assessment, as well as revisions made recently to more accurate since the Facility is currently offering a reflect wastes committed through user contracts, Table 1 has competitive price for sludge disposal. The projected maximum been developed to estimate and project the amount of wastes (overall) estimates do not assume any canister users from that may be managed by the Facility. It is noted, that due to non-committed companies. the proprietary nature of MRC's marketing and user contract data, only summaries are included in the Table 1 characterization of the Facility's primary market. it is also noted that the values in Table 1 have been developed in 4 categories as described below: Contractual Commitment - Guaranteed revenues based upon signed contracts with MRC. Anticipated amounts from committed com anies - Amount of waste expected at the Facility based on h stor ca effluent data, personal conversations and site visits. Due to the °put or pay" provisions in the contract, the contractual commitments are lower than the actual anticipated quantities. Therefore, this category represents a more accurate estimate of the waste which will actually be received by the Facility under current contractual commitments.. A-11 A-12 A a
