The inspection report is attached. The following observations were made:
1.The Town of Cary operates a wastewater collection system consisting of approximately 843 miles of
gravity sewer, approximately 78 miles of force main and 43 duplex pump stations that serves the Town
of Cary and any deemed permitted satellite communities and the tributary wastewater collection
systems serving the Raleigh Durham Airport Authority and the Town of Apex subject to their own
individual collection system permit (this description is from the permit, and will need to be updated
during the next permit renewal cycle). The current permit expires on November 30, 2023. A renewal
application should be submitted at least 180 days prior to expiration of the current permit.
2.The collection system is classified as a CS-4. Donald Smith is the Primary Operator in Charge (ORC),
and is a certified CS-4 Operator. The Division’s database shows eight backup Operators (bORCs), all
certified CS-4 operators.
Many staff members were present during review of permit-required documents, records and reports.
The following documents were reviewed:
x Public Education Program for Fats, Oils & Grease;
x Sewer Use Ordinance
x Grease Trap Ordinance
x Capital Improvement Plan;
x Records for annual system-wide inspections
x Bi-annual High Priority line inspections
x Annual 10%+ cleaning records
