I) Brief description of facility activities that occur on -site:
Facility is a 21 million gallon per day (MGD) wastewater treatment facility. Facility receives
wastewater from across the City of Winston-Salem and treats it prior to discharging the treated water.
I) Ultimate Receiving Waters: Muddy Creek/South Fork Muddy Creek
TMDL stream ®Yes ❑No If Yes, What Pollutants of Concern: Total Suspended Solids
Part 1 - Stormwater Controls
1. Best Management Practices (BMPs)
a. List the controls (structural or non-structural) emnloveci by the
E.g., Oil Water separators, cleaning schedules, structural BMP maintenance records
1. Waste roll -off container undercover at headworks
2. Sweeping and Dust Suppression performed during active construction
3. Secondary Containment for various chemicals and fuel sources stored onsite.

b. Are the non-structural BMPs reasonable & appropriate for the facility? ❑Yes ®No
Comments
The Lime Slurry Tank area needs to be placed on an increased cleaning frequency, since
Stormwater staff observed refuge calcium carbonate within the immediate open
environment.
c. Are stormwater control measures (SCMs) installed correctly, maintained, and effective operating condition?
Comments
®Yes ❑ No ❑ N/A
The Riprap channel that discharges to SDO-010 acts as a SCM at the facility for
stormwater retention from the upland subbasin.
2. Provide a brief description of other controls that manage/prevent/minimize stormwater runoff
(e.g., erosion and sediment controls, inlet protection/control at storm drains, diversion structures):
All outfalls at the facility discharge to a vegetated area, wooded or lowland grasses, which assist in
the removal of potential pollutants before surface waters.
Part 2 — Stormwater Discharge Outfalls (SDOs)
1. Any evidence of discharge to receiving waters/MS4 from the SDOs? (e.g.: stormwater runoff, dry weather
discharge, co -mingling of process wastewater, trash, debris, oil and grease): ®Yes ❑No
Comments
On the second reinspection dated 5-17-22, catch basin #13.3 had no evidence of discharged
waste lime material from the contracted supply vendor. Despite that, the supply vendor
and Utilities staff must complete additional training of appropriate good housekeeping
practices to eliminate all future illicit dumping of waste lime material into the drainage
system of SDO-013.
2) Do the stormwater outfalls on -site correspond with those listed on the site map in the Stormwater Pollution
Prevention Plan (SWPPP)? ®Yes ❑No
Comments
Please place the updated SDO map into your SWPPP.
