V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
A compliance inspection was performed on 4/12/19 as part of the permit renewal process. Mr. Emamian assisted with
the inspection. His cell#is 919-489-1900. Mr. Emamian stated that the septic tank was pumped in 2018. The
chlorinator had the correct tablets and were present and contacting the water. The pump tank alarm(audio and visual)
were working. The pumps are on a timer and do not have a rain sensor. There are I 1 spray heads in the irrigation
field. The pump was turned on and the spray heads did turn on for a moment but there was not enough water in the
tank for them to run long. They did appear to be operational. There is a two-strand fence around the irrigation area as
well as taller fencing to try to keep deer out.There was no ponding in the irrigation area.
During the inspection,we discussed the possibility of switching from spray heads to drip irrigation. I told Mr.
Emamian, that if he wanted to switch irrigation methods that would require a permit modification.
On the day of the inspection,the system appeared to be operational and well maintained.
