Subject: Compliance Evaluation Inspection
Permit WQCSD0311
Facility Name: Lake Ridge Aero Park Collection System
Durham County
Dear Mr. Becker:
On August 111, 2022, Josh Brigham of the Raleigh Regional Office conducted a compliance evaluation
inspection of the Lake Ridge Aero Park Collection System. The purpose of this inspection was to ensure
compliance with the subject collection system permit. During the inspection, the guidance of Wayne
Alford, ORC, was greatly appreciated.
This compliance evaluation inspection consisted of the following:
• Review of the 15A NCAC 02T .0403 permit requirements;
• Review of the owner/facility information;
• Review of records; and
• On -site inspection of the collection system and pump station units.
Findings during the pre -inspection file review were as follows:
1. The subject facility is not classified and currently does not have designated operators.
2. The Lake Ridge Aero Park Collection System has had no reported Sanitary Sewer Overflows since
the last inspection on October 25, 2018.
Findings during the inspection were as follows:
3. The Lake Ridge Aero Park collection system has one pump station that was visited during the
inspection. The pump station had secured access and exhibited very little to no waste build-up. The
pump station is monitored daily through telemetry and inspected weekly. Inspection records were
available on site. The high-water float was used to trigger audio and visual alarms and all functioned
normally. No issues were noted.
4. A map of the sewer system was available and contained all required information.
5. The Lake Ridge Aero Park collection system has a Fats, Oils, and Grease Program. Materials are
distributed to residents bi-annually.
6. The Lake Ridge Aero Park collection system has one high -priority line. It is inspected regularly and
documentation was available.
7. A Spill Response Action Plan was available for review during the inspection. It contained all required
information.
