MEMORANDUM
TO: File
FROM: Carl E. Lawson, Jr., Hazardous Waste Inspector
SUBJECT: Kaleidoscope Imprints
103C Mid Tech Drive
DATE: August 29, 2011
The Handling and Storage of Toxic or Hazardous Materials License for
Kaleidoscope Imprints has included a restriction prohibiting screen reclamation
and the use of screen reclaiming chemicals. Screen reclaiming is the process in
which the imprint screens are cleaned of ink using a solvent.
This restriction was included for the first time on the 1997-98 license apparently
in response to an evaluation in 1994 by the hazardous waste inspector of that
time. The evaluation was referenced in a letter to Kaleidoscope owner Mr.
Steven Karras. At the time Mr. Karras proposed the use of a screen washing and
reclaiming unit by the name of Splitter Jr. and the restriction was apparently
meant to ensure that only screen washing of emulsion and not screen reclaiming
of ink was performed with this system. According to Mr. Karras the Splitter, Jr.
system was only in service a short time.
Kaleidoscope has cleaned screens of ink for some time as mentioned in their
business proposal of 1987. Furthermore, solvent storage and disposal is listed on
their inspection reports dating back to the early 1990s.
Kaleidoscope cleans screens of ink using solvent in a parts washer basin. The
entire unit is inside a dedicated room that is a concrete containment area and
has explosion-proof wiring. There is no discharge from this system. Solvent is
recycled and lost only due to evaporation. Accumulated solvent sludge and
system filters are removed periodically by Safety Kleen, a licensed hazardous
waste hauler. The removals are documented on hazardous waste manifests.
Based on the above screen cleaning method which is fully contained, produces
no discharge and includes proper documentation of hazardous waste removal
the Health Director agreed to remove the restriction banning screen reclamation
and reclaim chemicals beginning with the 2011-12 year.
