FROM: Carl E. Lawson, Jr., Hazardous Waste Inspector
SUBJECT: Kaleidoscope Imprints
DATE: February 15, 2008
I inspected Kaleidoscope Imprints at 103C Mid Tech Dr. over two days, 2/5/08
and 2/14/08. The inspection was completed over two different days due to the
availability of personnel familiar with the business operations. Some key
personnel were attending a trade show during my first visit. Waste Removal is
handled by the following companies in the described ways.
Waste Mineral Spirits and Sludge
Waste mineral spirits and sludge are generated from part of the screen cleaning
process in which screens are cleaned of ink inside an enclosed, bermed room
with a screen cleaning machine that recycles solvent. Waste solvent and residual
sludge are periodically removed by Safety Kleen. This is a closed-loop process.
Screen Cleaning Machine Solvent Filters
Filters within the screen cleaning machine that filter the solvent during the
recycling process are disposed of by Safety Kleen.
Diluted Emulsion/Water Mixture
Emulsion used to create designs on the silk screens is cleaned using a water
washing process. All water is triple-filtered and reused until it is no longer
effective. Once no longer usable the water/emulsion mixture is manually drained
into a separate drum for removal by Safety Kleen. Safety Kleen classifies the
mixture as a nonhazardous material.
