Dear Mr. Best:

Subject: Compliance Evaluation Inspection
Carol Woods Collection System
Permit No. WQCSD0374
Orange County
On January 29, 2020, Jason Robinson and Chris Smith of the NC Division of Water Resource's Raleigh
Regional Office (RRO) conducted a compliance evaluation inspection of the Carol Woods Collection
System. I would like to thank you and Mr. Steve Dills (Manger of Maintenance & Engineering) for your
help.
The inspection report is attached. The following observations were made:
1. The Carol Woods Retirement Community's wastewater collection system is covered by a
Deemed Permit (WQCD0374). "Deemed" permitted systems are permitted by regulation (no
individual permit) and must meet the requirements of 15A NCAC 02T.0403 (attached). If the
system exceeds an average of 200,000 GPD, the system may need to apply for an individual
State Collection System Permit.
The retirement community includes approximately 500 residents. The collection system has
approximately 35 manholes and three grease traps. There are no pump stations or high -priority
lines. The Collection System flows into the Orange Water and Sewer Authority's Collection
System (OWASA: WQCS00031) in the Southeastern side of the property and appears to flow off
property towards Weaver Dairy Rd.
3. Staff does a good job of effectively maintaining and operating the collection system to prevent
any contravention of groundwater standards or surface water standards (15A NCAC 02T .0403
(1))
4. A hard copy of the map was available for review. The map shows Carol Wood's wastewater
lines as Orange and OWASA's lines as green. The map is complete, with the exception of flow
direction and approximate age of pipe. Please add the direction of flow (15A NCAC 02T .0403

S. A Sewer System Operation and Preventive Maintenance Procedure document was found in
DWR's file for this Collection System that was last updated in December 2014. This document
should be updated and an overflow response Plan should be added. 15A NCAC 02T .0403 3
6. The system has 3 grease traps: Dining Hall, Health Care Center and Building Eight. The grease
traps are typically pumped monthly. The Accounting Office receives and keeps invoices for
pumpings. Grease educational material is posted on boards and the community website has
education material available.
The grease trap at the Dining Hall was opened and observed during the inspection. It appeared
to need pumping soon.
Manholes are inspected once a quarter. ABE Utilities clean the lines as needed. Roots are
treated when OWASA treats their nearby lines. Invoices are kept for these actions. Please keep
a log that shows dates of all cleaning, inspections, grease trap pumping, etc. in one place. (15A
NCAC 02T .0403(1), (6) & (10)).
8. Two spills have reported at this collection system. A 1,080-gallon spill was reported in May 2013
and a 3,750-gallon spill was reported in March 2015. Please be reminded that spills greater than
1,000 gallons, and any discharges that reach surface waters (regardless of size) shall be reported
to the Department as soon as practicable, but no later than 24 hours after the discharge has
occurred, as required by 15A NCAC 02B .0506(a) and G.S. 1430215.2C.
Manhole 10 is near a pond and where a previous spill occurred. This manhole was opened and
observed during the inspection. No issues were observed. Another manhole near the system's
connection to OWASA's system was opened and observed. The flow appeared to be slightly
impeded. Carol Woods staff was going to look into this further.
9. Please make sure to document how all Deemed Permitted Requirements of 15A NCAC 02T are
met (15A NCAC 02T (10).
Thank you for your cooperation. If you have any questions regarding the attached reports or any of the
findings, please contact Jason Robinson at Jason.t.robinsonPncdenr.gov.
