Title:SULFURIC ACID RECYCLING IN THE SEMICONDUCTOR INDUSTRY
RCRA Online Number:14736
Date:11/30/2000
To:Scott
From:Cotsworth
Organization of Recipient:NA
Description: Secondary materials used or reused as ingredients in an industrial process to make a product are excluded from RCRA hazardous waste regulation. “Reclaimed” secondary materials are not eligible for this exclusion. Filtration occurring near the end of the process when it is already in essence a completed product may not constitute reclamation. The filter removes only minute quantities of particulate matter to guarantee the physical quality of the product, not to reclaim the secondary material in any meaningful sense (SEE ALSO: 50 FR 634; 1/4/85 and Memo, Straus to Lawrence; 5/30/86 (RO 11159)). Water added to the input acid is necessary for the final product and does not dilute the wastestream to remove a hazardous waste characteristic or circumvent regulation. (SEE ALSO: Memo, Lowrance to Directors; 4/26/89 (RO 11426))
