SUMMARY
This facility maintains 4 outfalls (001, 002, 003 and 004). The source of wastewater for the outfalls is once
through cooling water. The permit stipulates that outfalls 001 through 003 be monitored (with no limits) for
flow, temperature and pH. The permit was recently modified to include Outfall 004 for periodic discharges
of stormwater from secondary containment around the transformers. In order to prevent contamination of
the receiving stream, the facility is required to use Best Management Practices. Discharge Monitoring Reports
have to be submitted annually.
The receiving stream (Yadkin River) is classified as WS-IV and B CA waters from a point 0.6 mile upstream
of High Rock Lake darn to Badin Dam. This reach is not listed on the 303(d) list as impaired water.
COMPLIANCE SUMMARY:
The facility has an excellent compliance history. During the last 5 years, facility did not violate the permit
terms and conditions.
PROPOSED CHANGES:
None
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: July 1 (est.).
Permit Scheduled to Issue: August 24 (est.).

limits). Basin Coordinator to make case -by -case decision.

• 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)
