Re: NPDES Permit Application for Southchem, Inc., ,
Dear Mr. Cashion:
This letter is to confirm our telephone conversation on May 16, 1995, regarding the NPDES
permit application submittal for the Southchem, Inc. facility located at 2000 E. Pettigrew Street,
Durham, North Carolina.
On March 3, 1995, prior to the deadline for submitting the NPDES permit application, we
talked with Mr. Steve Ulmer, Division of Environmental Management, regarding the potential delay in
submitting the NPDES permit application for the above-referenced facility due to sampling problems
associated with the weather. Most of the significant storm events occurred at night or within 72 hours
of the previous storm event. As a result we were not able to collect the storm water samples from the
facility outfalls. Mr. Ulmer indicated that the 90-day deadline was informal and a formal extension was
not required. He also indicated that he would update you on the status of the Southchem permit
application based on our conversation.
As I informed you on May 16, 1995, we are currently waiting for a significant storm event for
sampling. Upon collection/analysis of the storm water samples, a NPDES permit application will be
submitted as soon as practicable to the Division of Environmental Management
Thank you for your cooperation. If you have any questions please contact myself or Najun
Shetty at [phone].
Sincerely,
GE' . •,•7 & II INC.
