Compliance History
• Four (4) NOVs issued for exceeding BODS limit during 1996-97. Levels fluctuated significantly
during 1996 and were more controlled in 1997 (one violation).
• 1997 Compliance Inspection Report indicated dosing problem had been repaired, but distribution
lines needed attention.
• Flows typically 0.004 MGD.
• Effluent TSS values averaged less than 20 mg/I, and ammonia values normally less than 15 mg/1.
• Effluent temperatures okay.
Additional Comments
• Dilution ratio is 734:1 (see attached calculations), therefore no fecal limit is recommended (ratio is
less than 331:1). No fecal monitoring done in the past, so no data available to assess current levels.
What kind of disinfection is being used?
• Calculations indicate that no ammonia limit is necessary (allowable concentrations above 35 mg/1).

NOTES FOR HAPPY VALLEY ELEMENTARY
PERMIT RENEWAL (NCOO41181)
Wastewater discharge from Happy Valley Elementary School (Happy Valley, Caldwell
County) to the Yadkin River in the Yadkin Pee -Dee Basin.
15A NCAC 2B .0300 Index # 12-(1): Classified as C-Tr in 4/15/63.
ATC Information:
• None in file
Basinwide Plan Information:
• Water quality in the upper Yadkin River at Patterson and Wilkesboro has improved
over the last decade, but sedimentation continues to be an issue. Numerous
streams draining the Blue Ridge Mts. have good or excellent water quality. (This
discharge is into the Yadkin in the upper portion of the Yadkin's watershed.)
• Nearest ambient station (02111000) is near Patterson (just upstream of discharge).
Yadkin in this area is supporting uses.
Correspondence:
• 3 NOVs issued for BOD violations in 1996 and 1 in 1997.
• 1997 Compliance inspection report noted that a dosing tank problem had been
repaired, but distribution lines needed attention.
DMR Review:
• Flows typically 0.004 MGD.
• TSS fluctuates, normally less than 20 mg/1; some exceptions in 1996.
• BOD5 fluctuates, levels more controlled in 1997 (below 30 mg/1).
• No fecal monitoring.
• Temperatures okay.
• Ammonia usually less than 15 mg/1.
General Comments:
Currently facility does not monitor for fecal. Calculations indicate does not need a
limit, but for facility should be monitoring. Ammonia toxicity calcs. show no limit
necessary (conc. above 35 mg/1).
Facility does discharge to Trout waters; however, does not appear to use chlorine for
disinfection. Division policy is to require a TRC limit for all dischargers to Tr waters,
but I will footnote that monitoring only applies if chlorine used to disinfect.
Expiration date to be assigned to this permit is October 31, 2003.
