RE: Waste Management of Carolinas, Inc. — Winston Salem Hauling
Division of Water Quality NPDES General Permit No. NCG080000
Certificate of Coverage No. NCG080038
Notification of Tier Three Monitoring
Dear Mr. Gantt:
The purpose of this letter is to notify your office that the referenced facility is
proceeding with Tier Three monitoring, as required under our General Permit. Outfall
No. 1 at the facility has exceeded the benchmark value for total suspended solids (TSS)
on four occasions. Furthermore, recent auditing of Winston-Salem Hauling's records
indicates that the facility did not properly execute the Tier One and Tier Two responses.
We want to assure the Department that this issue is of great concern to Waste
Management of Carolinas, Inc., and that the facility's compliance under the permit is a
high priority.
If you have any questions regarding this notification, please contact me at (336) 253-
0091 or by email at dmooreMAwm.com.
Sincerely,
Waste Management of Carolinas, Inc. — Winston-Salem Hauling
