SUBJECT: Compliance Evaluation Inspection
Dow Greensboro Groundwater Remediation
NPDES Permit No. NC0088773
Guilford County
Dear Mr. Cammin:
On September 28, 2018, Jenny Graznak, of this office, met with Chuck Bertz from Arcadis G&M
of North Carolina, Inc. to perform a Compliance Evaluation Inspection on the groundwater
remediation system at Dow Silicones Corporation in Greensboro. This type of inspection consists
of two basic parts: an in-office file review and an on-site inspection of the treatment facility.
The remediation system was shut down in October 2017 to conduct a year-long study in
conjunction with the NC Division of Waste Management to determine the final site remedy. The
system will remain down until a decision is made regarding future treatment. Ms. Graznak
confirmed that the system is no longer discharging. The permit requires quarterly monitoring, and
discharge monitoring reports are currently sent in with a "No Flow" designation. Please continue
to keep our office updated on the status of the system. If you have any questions regarding the
inspection or letter, please contact Ms. Graznak or me at [phone].
Sincerely,
Y- ,
