Susan,
The certification you received was for the Robersonville WWTP
Improvements - Phase I. The ATC Number was 026042ACC dated March 11,
1999. I believe Ralph referenced the NPDES permit instead of the ATC
permit. Hope this clears things up. Thanks.
>Charles - we received a certification from you guys signed by Ralph
>Mobley for Robersonville, dated 9/4/01. Do you know what that is for
>and which ATC that may have referred to? Thanks for any help. It also
>has a date of 3/8/95 - which I can't find anything we may have issued
>then to Robersonville, so I don't know what that refers to.

Project No. 026042ACC
Robersonville WWTP
Martin County
The Division received a letter of request for an Authorization to Construct on September 16, 1998 and
final plans and specifications for the subject project have been reviewed and found to be satisfactory. Authorization
is hereby granted for the construction of modifications to the above referenced 1.8 MGD wastewater treatment
facility operated by the Town of Robersonville discharging treated wastewater to Flat Swamp in the Tar -Pamlico
River Basin.
Specifically, authorization is granted for the construction/installation of:
• An influent splitter box;
• A second grit removal chamber;
• Anaerobic/anoxic basins consisting of four anaerobic zones and two anoxic zones;
• Two (2) internal recycle pump station;
• Modifications to the existing clarifier splitter box;
• A 50 foot diameter secondary clarifier;
• A new intermediate lift station;
• A second chlorine contact chamber accommodating dechlorination;
• An additional RAS pump;
• Two (2) aerobic sludge digesters;
• A laboratory/administrative building; and
• All necessary piping and appurtenances.
Additionally, after a body of operational data has been collected from the above approved facilities. the need
for carbon source addition should be considered.
These facilities are approved for a wastewater flow rate of 1.8 MGD. State law prohibits approval of
treatment facilities for flows that are not permitted at the time of Authorization to Construct issuance. As such,
should an NPDES permit modification be approved for expansion from 1.8 MGD to 2.4 MGD, the Town must
either apply for an additional Authorization to Construct for facilities needed to treat at 2.4 MGD or apply for a re -
rating of the existing facilities.
