• Temperature monitoring has changed to daily, in accordance with 213 .0500 requirements for Class
II facilities.
• Monitoring for total nitrogen and phosphorus has changed to monthly. This change is consistent
with an effort to gather more data about nutrient loading in this portion of the watershed.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable to you. you have the right to an adjudicatory hearing upon written request within thirty (30)

Special Condition(s): N/A.
Compliance History
• 7/7/97 Compliance Sampling Inspection: I fecal and 1 TRC violation from `96-'97. No significant
problems noted; facility has maintained a fairly good compliance history.
• Flow typically were 0.003-0.007 MGD, until the latter part of '98—increased to as high as 0.01
MGD.
• TP typically <3 mg/l,TN around 20-45 mg/I in '98; <10 mg/I in `97. Ammonia normally<1 mg/l.
• pH and temperatures fine. TRC 0-20 µg/I.
• TSS usually<10 mg/l; fecal <20/100 ml.
• BODS <15 mg/l, and DOs 5-10 mg/I, depending on season.
Additional Comments
• There are no ambient monitoring stations near this discharge. Fryes Cr flows to Muddy Cr, which
has water quality problems near the headwaters, as well as below Salem Cr confluence (Fryes Cr is
further downstream).

Staff Review and Evaluation
NPDES Wastewater Permit (NC0083941) Fact Sheet
• Most streams in agricultural areas were assigned a good-Fair rating, often with a severely degraded
habitat. The normal rocky riffle areas of piedmont streams were reduced or entirely eliminated by
massive inputs of coarse sand, reducing the available habitat for benthic macroinvertebrate and fish.
Fryes Cr is a typical agricultural stream with a Good-Fair bioclassification.
• In 1990, DWQ developed a field-calibrated QUAL2E model for Salem and Muddy Creeks, extending
from Winston-Salem's Archie Elledge WWTP to the Yadkin River. More recent instream and
effluent data suggest that the assimilative capacity of these creeks may have been over-predicted. No
strategies for this stream are specified.

NOTES FOR SPRING CREEK
PERMIT RENEWAL (NC0083941)
Wastewater discharge from Spring Creek Subdivision (Danbury, Davidson County) to
Fryes Creek in the Yadkin-Pee Dee River Basin.
15A NCAC 2B .0300 Index #: Fryes Creek classified as WS-IV (##12-94-15-(2)) in
8/3/92.
ATC Information:
• 4/21/95 ATC issued for construction of the plant (does not specify capacity).
Basinwide Plan Information:
• This sub-basin (03-07-04) has seen effects from some point sources on stream biota;
severe effects of urban runoff have been seen in poor bioclassifications assigned to
Grants Cr and Town Cr during studies in 1990 (each listed on the 303(d) list.
• Chemical samples from ambient sites indicate that most streams are very turbid,
but low DO is rarely a problem. Point source dischargers and urban runoff lead to
high conductivity levels in Salem Cr, Muddy Cr, Grants Cr, Abbotts Cr, and
Crane Cr. Many of these streams also have high concentrations of nitrogen and
phosphorus, but long-term data indicate these have been reduced by improved
wastewater treatment.
• There are no ambient monitoring stations near this discharge. Fryes Cr flows to
Muddy Cr, which has water quality problems near the headwaters, as well as below
Salem Cr confluence (Fryes Cr is further downstream).
• Most streams in agricultural areas were assigned a good-Fair rating, often with a
severely degraded habitat. The normal rocky riffle areas of piedmont streams were
reduced or entirely eliminated by massive inputs of coarse sand, reducing the
available habitat for benthic macroinvertebrate and fish. Fryes Cr is a typical
agricultural stream with a Good-Fair bioclassification.
• In 1990, DWQ developed a field-calibrated QUAL2E model for Salem and Muddy
Creeks, extending from Winston-Salem's Archie Elledge WWTP to the Yadkin
River. More recent instream and effluent data suggest that the assimilative capacity
of these creeks may have been over-predicted.
Correspondence:
• 7/7/97 Compliance Sampling Inspection: 1 fecal and 1 TRC violation from `96-'97.
No significant problems noted.
DMR Review `97-`98:
• Flow typically were 0.003-0.007 MGD, until the latter part of '98—increased to as
high as 0.01 MGD.
• TP typically <3 mg/1, TN around 20-45 mg/1 in '98; < 10 mg/1 in `97. Ammonia
normally < 1 mg/l.
• pH and temperatures fine. TRC 0-20 µg/l.
• TSS usually < 10 mg/l; fecal <20/100 ml.
• BOD5 < 15 mg/1, and DOs 5-10 mg/1, depending on season.

NCO083941 BAB
General Comments:
Facility appears to be well maintained and has had few compliance problems since
it was built.
Per Steve Pellei's 12/7/98 Memo regardingg nutrient monitoring in the Yadkin
basin, this facility should be given monthly 7Nand TP monitoring.
