Dear Mr. Weaver:
We are requesting a renewal of the permit NCO081621 for the Muddy Creek WWTP.
The current permit is scheduled to expire October 31, 1999. There have been no changes
at the facility since issuance of the last permit.
The permit adequately describes the wastewater treatment plant, except your cover letter
referred to the plant as the "MUD CREEK WWTP". The correct name is "MUDDY
CREEK WWTP". We would like to continue with the tiered flows of .075 MGD,
.150MGD, .300 MGD in the new permit.
Our sludge management plan consists of truck hauling excess bio-solids to the Rocky
River Regional Wastewater Treatment Plant, NPDES Permit No. NC0036269, for final
disposal. The Rocky River Regional Wastewater Treatment Plant is owned and operated
by the Water and Sewer Authority of Cabarrus County.
The permit renewal Package Checklist is enclosed. If you have any questions, please
