SUMMARY
This facility maintains one outfall, 001. The facility applied for and was granted an authorization to construct
for two underdrained alum sludge lagoons in January 1996. Wastewater's from filter backwash and basin
wash water is treated using holding and decant lagoons then discharged into an unnamed tributary 0.4 miles
upgradient of the confluence with Tuckertown Reservoir. The Tuckertown Reservoir eventually discharges
into the Yadkin River.
The receiving stream (unnamed tributary to the Yadkin River) is classified as WS-III and B waters and is not
listed on the 303(d) list as impaired water. The May 1998 Yadkin -Pee Dee River Basinwide Water Quality
management Plan concludes that this stream supports its designated uses.
TOXICITY TESTING:
Current Requirement: None
Recommended Requirement: None recommended.
COMPLIANCE SUMMARY:
Plant come on-line in July 1998, since that time there have been no compliance problems. There een two
NOVs issued for untimely submittal of DMRs.

INSTREAM MONITORING:
This facility is required to monitor turbidity of the receiving stream both upstream and downstream from the
outfall. A turbidity limit has been implemented.
PROPOSED CHANGES:
Denton Water Treatment Plant Fact Sheet
NPDES .Renewal
Pco:I I

•
The limit and monitoring requirements outlined in the previous permit remain consistent with the minimum
requirements for this type of facility. Therefore, it is recommended that this permit be renewed without
changes.
It is division policy to implement Fe monitoring for all water treatment plants and Al monitoring if alum is
utilized during the treatment process. Most facilities utilize either ferric sulfate or alum but rarely both,
therefore the need for monitoring of both Fe and Al should be examined. Permits should require that either
Fe or AL be monitored (depending on which coagulant is used) with a footnote requiring the other be
monitored if used in the treatment process.
