1 The temperature of the effluent will be regulated so that the temperature of the receiving stream
does not increase by more than 2.8 °C above the natural water temperature. In no case should the
receiving stream temperature exceed 32 °C due to the facility's operation. Temperature of the
effluent may be obtained anywhere downstream of the heat exchanger effluent that is representative
of the discharge.
2 The pH of the effluent shall not be less than 6.0 standard units nor greater than 9.0 standard units,
unless ambient river conditions prevent compliance with this range.
Monitoring results obtained during the calendar year shall be recorded and reported on a Discharge
Monitoring Report (DMR) form and postmarked no later than January 30th following the completed .
reporting period. Samples obtained for monitoring purposes may be collected anytime during the calendar
year.
There shall be no discharge of floating solids or visible foam (other than trace amounts) in the effluent,
unless ambient river conditions prevent compliance.
A. (2) BIOCIDE CONDITION
There shall be no chromium, zinc or copper added to the treatment system except as
pre -approved additives to biocidal compounds.
The permittee shall obtain approval from the Division's Aquatic Toxicology Unit prior to the use of any
biocide (not previously approved by the Division) in the effluent discharged under this permit. Approval for
use of any biocide not previously approved should be requested at least 90 days in advance of any planned
usage.

1 The tailrace shall be visually inspected for oil sheen attributed to facility operations on a weekly
basis in conjunction with inspections of the floor sump and rope skimmer. Confirmation that a
visual inspection was conducted shall be recorded in the operating log for the facility and provided
to the Division upon request.
2. The pH of the effluent shall not be less than 6.0 standard units or greater than 9.0 standard units,
unless ambient river conditions prevent compliance with this range.
Best Management Practices (BMPs) must be employed to ensure that excessive pollutants are
not discharged to the surface water of the state. These practices should include as a minimum,
routine maintenance of the rope skimmer type oil/water separator and cleaning accumulated
sediment in the bottom of the sump annually.
Chemical wheel pit cleaning is permitted on a monthly basis. When wheel pit cleaning occurs, the
tailrace shall be inspected visually for foam and oil. Cleaning shall be conducted only with pre -
approved solvents. Should the Permittee wish to change solvents, a written request should be made to
the Division including the MSDS for the proposed solvent.
Mechanical cleaning operations which do not contribute any wastewater to the discharge are not
limited by this permit. Non -discharging cleaning operations may be conducted as often as necessary
to ensure safety and proper facility operation.
Monitoring results obtained during the calendar year shall be recorded and reported on a Discharge
Monitoring Report (DMR) form and postmarked no later than January 30th following the completed
reporting period. Samples obtained for monitoring purposes may be collected anytime during the
calendar year.
There shall be no discharge of floating solids or visible foam (other than trace amounts) in the effluent,

no limits) for flow, temperature and pH. Stormwater from the area beneath the penstocks is
discharged from outfall 004. Discharge monitoring reports have to be submitted yearly.
The receiving stream (Yadkin River) is classified as WS-IV and B CA waters from Badin dam to a
point 0.5 miles upstream of Falls dam. This reach is not listed on the 303(d) list as impaired water.

YES4,
This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes). Include conventional WTPs in this group.
YESThis is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan), 303(d)
listed, toxicity testing, instream monitoring, compliance concerns, phased
limits). Basin Coordinator to make case -by -case decision.
YES_ This permit CANNOT BE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for.BOD, TSS,
etc)
• Limits based on reasonable potential analysis (metals, GW remediation organics)
• Permitted flow > 0.5 MGD (requires full Fact Sheet)
• Permits determined by Basin Coordinator to be outside expedited process
