The effluent dischar a shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at n effluent concentration of 50%.
The permit holder s all perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North
Carolina Phase II C onic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The tests will be per ormed during the months of January, April, July and October. Effluent sampling for this testing
shall be performed a the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit,
then multiple-conce tration testing shall be performed at a minimum, in each of the two following months as described
in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent

alternate monitorin requirements or limits.
NOTE: Failure to

SUMMAR
This facility is a major municipal treatment plant operating in Yadkin County. It was originally
permittedin 1980 at a flow of 1.0 MGD discharging into Flaw Branch. The outfall was relocated to
North Deep Creek in 1992. A permit application for expansion to 2.5 MGD was processed in
1997. A wasteload allocation completed by Andy McDaniel in January of 1997 for expansion to 2.5
MGD recommended effluent limitations more stringent than secondary in order to protect the
State's 5.0 mg/L dissolved oxygen (DO) standard. An authorization to construct (020338ACD) for
that expansion was issued on June 19, 1997. The engineer's certification for that project was
subsequer.tly received July 16, 1998.
REASON
ABLE POTENTIAL ANALISYS
Reasonable potential analyses were conducted for arsenic, cadmium, cyanide, chromium, fluoride,
lead, selenium, silver, copper, zinc, and nickel (see attached). The following parameters are
monitored through the permit: arsenic, cadmium, chromium, copper, cyanide, fluoride, lead, silver,
zinc. Thfollowing parameters are monitored through the pretreatment program: arsenic,
cadmium, chromium, copper, lead, mercury, molybdenum, nickel, silver, selenium, zinc, aluminum,
oil and grease, phenol.
The existing monitoring frequency for silver, zinc, and copper remains unchanged. Due to the
facility's excellent toxicity record, limits for these action level standards will not be implemented,
but moni . ring will remain.

NCE SUMMARY:
e been reviewed for the period January 2000 through September 2003. The facility has
stently passing it's WET tests and had very few permit limit violations. On July 11, 2002
violated the daily maximum limit for cadmium, and a civil penalty was assessed.
the facility claimed that it was a laboratory error and submitted a corrected lab report and
MR with a cadmium concentration below detection level. On April 17, 2001 the facility
H limit. As a response the town has budgeted for a new chemical feed equipment.
INSTREA I MONITORING:
Instream n onitoring is required for temperature, dissolved oxygen, fecal coliform, and conductivity.
Analysis of DO and temperature data showed that facility has no significant negative impact on the
water quality in the receiving stream (table is attached). Fecal Coliform concentration in the effluent
has been consistently below 200/100 mL. According to 1larch 2003 Yadkin -Pee Dee Basinwide
Plan, North Deep Creek is Rated as Supporting.
PROPOSED CHANGES:
• Monitoring Frequencies: The monitoring frequency for cadmium, and oil and grease has been
reduced to quarterly due to the removal of the permit limit. The monitoring frequency for
arsenic, cadmium, and chromium has been reduced to quarterly based on reasonable potential
analyses. Weekly monitoring for lead and fluoride have been introduced due to the
implementation of the new permit limit.
• Limitsf Based on Reasonable Potential Analysis, limits are being introduced for lead and
fluoride. Weekly average limit for ammonia nitrogen has been added to the permit. Limits for
oil and grease and cadmium have been eliminated based on effluent data during review period.
Oil and grease limit was eliminated because facility has a very good compliance record and
never violated oil and grease limit.

El . Toxicity Testing
To whom it may concern,
In filling out the renewal application for the Wastewater Treatment Plant in Yadldnville, to my knowledge we never recieved a letter telling us to check
for two species in the Toxiclyest. In the past four and a half years we have checked a total of 18 tests for Ceriodaphnia dubia and they have all passed. I have
talked with Mark McIntire andMike Mickey. Mark said for us to run 4 tests for Fat Head Minnows in the remainder of the year. Those tests will take place in July,
August, September and Octobr. I hope this will meet the requirement. Hydro Analytical Laboratories in Clemmons, NC has run all of our Toxicity tests for us. If
you have any questions about hese tests feel free to call Hydro at 336-766-7846 or myself at 336-679-2184. Sorry for the inconvenience.
