Dear Mr. DiMatteo:
We are writing in response to your letter dated March 13, 2020 NOTICE OF VIOLATION & INTENTTO
ACCESS CIVIL PENALTY Tracking No.: NOV-2020-LV-0199, and would like to provide justification as to why a
civil penalty of any amount would impede our efforts in rectifying the issues we are experiencing.
We are continuing to focus on the cleanliness of the chlorine contact chamber as we feel the organics that
get trapped in it is the culprit. We have followed all recommendations given to.us from State officials as
well as that of the North Carolina Rural Water Association. We have recognized that as the water warms up
above 20°C that we see the formations of the Dichlorobromomethane and this is when we put in place all
apparatus that has been suggested'. The following is a list of the things we have done as well as steps we
take to combat this pollutant;
• Installed a submersible pump with an aspirator before sampling area to give effluent a
boost of oxygen to help strip the Dichlorobromomethane from water.
• Installed a disinfectant recirculation pump to use the plants effluent to re -chlorinate the
water in lieu of using Town water which was found to contain large amounts of
Dichlorobromomethane.
• Increased draining and cleaning of clarifiers and chlorine contact chamber.
• Increased disinfection and cleaning of tertiary filters.

• Reduced the chlorine pounds per day feed as well as decreased Sulfur Dioxide feed but also
maintaining limits of fecal coliform colonies.
As I have explained, we have continued to seek out and find solutions for this issue. We ask that no
monetary fine be levied against the Town of Denton as any amount will impede our efforts to return to
compliance and maintain compliance. Please note that as of the writing of this letter we have returned to
compliance. The results for April and May 2020 were <1.00 ug/L.
Thank you for your consideration and attention in this matter.
Sincerely,
Troy B. Branch
