July 19, 2023 — Inspection Summary — NC0037834
On June 29, 2023, Division of Water Resources staff Gary Hudson conducted a routine compliance
inspection at the Archie Elledge WWTP. Bonnie McKee and Matthew Lavigne were present during the
inspection. A review of the October 2022, and April 2023 eDMR was compared to laboratory bench
sheets. No discrepancies were noted. During the inspection, no violations or items of concern were
noted. The following treatment components were inspected:
Permit
The permit became effective on August 1, 2017, and expired on June 30, 2022. A renewal application
was submitted on December 28, 2021.
Odor Control:
The Archie Elledge WWTP has six carbon air scrubbers for odor control. Four are located at the
influent/preliminary treatment, one is located at the primary clarifiers, and one is located at the sludge
thickener. Carbon is replaced yearly. All units were operating properly during the inspection.
Preliminary Treatment:
Preliminary treatment consists of two mechanical bar screens, two grit classifiers, and two cyclone grit
chambers. All six units are rated at a maximum capacity of 50 million gallons pr day (MGD). All units
were operating properly during the inspection.
Primary Treatment:
Primary treatment consists of four large primary clarifiers. All units were operating properly during the
inspection.
Secondary Treatment:
Secondary treatment consists of activated sludge basins, and six secondary clarifiers. All units were
operating properly during the inspection. Magnesium hydroxide is used for pH adjustment when
needed.
Final Effluent:
Sodium hypochlorite is used for disinfection and sodium bisulfate is used for de -chlorination. The
effluent composite sampler is set to collect 140 ml sample every 28 pulses. The refrigerator
temperature was 5 degrees centigrade.
Sludge Digestion:
Sludge digestion consists of six floating cover anaerobic digesters.
Sludge Handling and Disposal:
All sludge is run through a gravity belt thickener before it enters the anaerobic digesters. After
digestion, the sludge is run through a dryer and turned into pellets. All of the dried pellets are sold to
a private contractor to be used as fertilizer.
