Based on the condition that the resultant sludge is a combination of three(3) independent waste streams (i.e. it appears each waste stream is being diluted by two(2) other waste streams) it would be prudent to require IBM to submit to EPA, or the landfill, monthly waste rates from each of the three(3) independent waste streams to ensure the contribution ratios are not dramatically changing. The removal of one waste process could potentially increase the hazardous components by 50% from the other 2 waste streams. If volume of sludge waste is a component in EPA’s calculations related to overall impact, then the increase, or reduction of a waste stream could impact the results. Thank you,
