Dear Sir or Madam,
Enclosed please find a copy of the Compliance Evaluation Inspection Report for the
inspection we conducted at the Mount Airy WWTP on July 10, 2024. Please note that in the
stormwater inspection report summary we ask that you create and maintain a S WPPP, review
site map and modify as necessary, revise stormwater locations as necessary, implement
appropriate preventative and good housekeeping practices to eliminate exposure, and analyze
and address the drainage Swale that displays several indicators of potential wastewater and
environmental impacts.
The report should be self-explanatory; however, should you have any questions, please do
not hesitate to contact Ashley Vikara at (336) 776-9655 or by E-mail at

Inspection Summary:
On July 10, 2024, a compliance inspection was conducted for the facility.We met with Chris Marion on site. During the
inspection the following issues were noted-
1- SWPPP has not been created or maintained on site. A SWPPP shall be created and maintained in accordance with
NCG 110000.
2. Additional outfalls were observed on site, not shown on the site map. Review site map and modify as necessary. Potential
additional outfall locations include the access road on the west side of drying beds; the woodline northeast of biosolids
loading area; perimeter west of headworks.
3. Stormwater outfalls are to be located before reaching surface waters and after any potential industrial impact. Consider
revising as necessary.
4. Biosoiids accumulation was observed on asphalt adjacent to loading area. Implement appropriate preventative
maintenance and good housekeeping practices to eliminate exposure.
5. Waste management equipment was observed in an area draining to a stormwater system. Implement appropriate
preventative maintenance and good housekeeping practices to eliminate exposure.
6. Drainage swale west of aeration basin displayed several indicators of potential wastewater and environmental impacts
(visual and odor). Analyze and address appropriately.
Please give the above items attention and the facility will be reinspected on or after August 13, 2024.
