SUBJECT: Compliance Evaluation Inspection & Continuing Notice of Violation
NOV Tracking #: NOV-2020-PC-0414
Pond Creek Wastewater Treatment Plant
NPDES Permit #NC0069761
Watauga County
Dear Mr. Davis:
Ron Boone, of the NC Division of Water Resources (DWR), Winston-Salem Regional Office (WSRO),
visited Pond Creek wastewater treatment plant on August 14th, 2020, to perform a Compliance Evaluation
Inspection (CEI). Your assistance and cooperation, as well as that of Randall Horney, Operator in Responsible
Charge (ORC), was greatly appreciated. Details of the inspection are recorded on the attached EPA Water
Compliance Inspection Report.
You're reminded that, in accordance with NC General Statute 143-215.6A, failure to comply with all
conditions of the permit subjects the Town of Beech Mountain to civil penalties not to exceed $25,000.00 per
violation, per day.
As there were deficiencies/violations noted during his inspection, please respond in writing to this
notice within 15 business days of receiving it. Your response should address each deficiency/violation
individually and provide a proposed corrective action with implementation schedule for each
deficiency/violation. Your written response will, in part, determine whether DWR will pursue any further
action against the Town of Beech Mountain regarding the deficiencies/violations contained herein.
If you have any questions or require further assistance, please contact Mr. Boone by phone at 336-776-
9690, or by email at ron.booneOncdenr.gov. You may also contact me by phone at 336-776-9700, or by email

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Plant appeared to be running well during the inspection. Mixed liquor was light to medium brown and
there was no foul odor. A settleability test revealed only about 20 percent solids after 30 minutes of
settling. The center well of the primary was heavily coated with solids and the aeration basin had nearly
100 percent coverage with a light to medium brown foam. Again, no foul odor present. The sludge
blanket was only 1 foot and the clarifier is 12 feet deep. There was a small amount of pin floc overflow
from the primary and secondary, but nothing out of the ordinary or significant. Lighting in the building
that houses the UV and effluent metering and sampling systems wasn't good enough to allow an
accurate assessment of water clarity in the flow trough. Best assessment is that is looked clear and
there were no foul odors inside the building.
The plant was issued a Notice of Violation for the previous inspection of July 2019 for not using flow
proportional composite sampling (FPCS) for influent and effluent samples. This is still the case. New
samplers, which will allow FPCS, are on site, but they were delivered without all the necessary parts,
and therefore have not yet been hooked up, as of the writing of this report. Latest report is that all parts
have now been received and installation is being scheduled.
No other problems, discrepancies, or violations were noted during the inspection.
