Site Visit Evaluation: Municipal Facility No. 1
Does the MS4 inspector's process include walking the entire facility and inspecting all points of discharge?
Entire facility — yes. It is evident that the outfall was inspected but was not done during the inspection of the facility during the
audit.
Did the MS4 inspector miss any obvious areas of concern? If so, explain:
Some drop inlets were inspected but not all. The main area missed was not inspecting the outfall from the facility, however when
asked about it inspectors knew exactly where it was.
Does the MS4 inspector's process include presenting the inspection findings to the facility contact?
Not facility contact specifically, Village of Clemmons does not employ a large amount of people, therefore if an issues is observed it
is delivered directly to the person responsible,
Inspection Results
Did the facility inspection result in any corrective actions to be implemented? If so, for what issue(s)?
Create a site specific SWPPP.
If compliance corrective actions were identified, what timeline for correction/follow-up was provided?
SWPPP was created and delivered to NCDEQ within 24 hours.
Notes/Comments/Recommendations
Facility is one of two owned by the Village of Clemmons, the other being village hall. Facility was very well maintained and given
that the office for the stormwater department is on site, the stormwater department has a very good working relationship with the
public works employees.

Inspection Results
Did the outfall inspection result in any work orders or maintenance requests? If so, for what issue(s)?
No.
Will a follow-up outfall inspection be conducted? If so, for what reason?
A yearly inspection will be performed but nothing will be followed up on because of this inspection.
Notes/Comments/Recommendations
Outfall was recently fixed due to common flooding problem. New outfall allowed for an increased flow. Inspections are done
regularly and this outfall is not a dry outfall due to small feeder stream that consistently flows. During the inspection homeowner
came by and spoke to Wesley and informed him about NCDOT runoff "staining" the stream. Homeowner obviously had a good
relationship with VoC Stormwater crew.
