Re: Draft NPDES Permit NC0088684
Dear Ms. Young:
We are in receipt of your letter dated July 22,2020 regarding the draft permit referenced above. After careful
review,we would like the following taken into consideration prior to issuing a final permit.
Efforts have been actively underway to correct reporting concerns as follows: 1
Hydro Services& Supplies, Inc.(Hydro)engineer services were retained in July to devise a scope of work and
provide associated costs to get the reverse osmosis(RO)system running properly,efficiently,and with an effluent
that is in compliance with State guidelines.
On August, 19, 2020,we received a report and quote for replacement of RO control board,feedwater solenoid
valve,and low-pressure switch(see enclosed quote).
The RO was shut down shortly after receiving the aforementioned notice from the State,and has remained shut
down since. We anticipate the RO system will not start processing water until all necessary repairs have been
completed by Hydro,and the effluent IDS is within compliance.
With regard to Item No.6 in your letter,we ask that in consideration of the steps taken that reporting will be
allowed to continue as one per month instead of the proposed two per month.
Please let me know if you have further questions regarding this matter.Thank you.
Sincerely,
bt)
