Dear Mr. Goodrich:
OCTO C T 1 4 2002
L li - WATER QUALITY
Pt. T SOURCE BRANCH
Delta Environmental Consultants, Inc. (Delta) is submitting this letter on behalf of our client, Chemical
Specialties, Inc. (CSI).
CSI would like to reduce the monitoring well sampling frequency for the compliance wells at the Harrisburg
facility from quarterly to semi-annually by skipping the January 2003 event and resuming in April 2003. We
would also like to request the NPDES permit for CSI Harrisburg be altered to reflect these changes.
Per an October 8, 2002 conversation with Mr. Mark Wilkins, a hydrogeologist with the NCDENR Division of
Waste Management (DWM), CSI has been granted permission to collect semi-annual groundwater samples from
the site compliance wells to meet the requirements of the facility's RCRA permit. Quarterly groundwater
sampling is no longer required to meet the conditions of CSI' s RCRA permit.
Reducing the compliance well sampling frequency in the facility's NPDES permit to concur with the
groundwater monitoring schedule in the facility's RCRA permit would be appreciated.
