On March 25, 2009. Myri Nisely of the Raleigh Regional Office conducted a compliance inspection of the
Weldon WWTP facility with the help of ORC Donald Crowder and Laboratory Analyst Bill Hux. Their help
greatly appreciated. The facility was in compliance. Attached is a checklist containing inspection details.
In early 2007 the ORC implemented a plan for identifying and removing causes of limit violations at the request
of this office. The plant has returned to compliance since that time.
• In anticipation of the new Total Chlorine Residual limit in the ug/1 range, the facility has obtained the
necessary meter and will obtain training by Greta Glover at the Roanoke Rapids Sanitary District soon.
The plant is urged to begin measuring and controlling to 28 ug/1 even before the revised permit arrives to
gain experience in meeting the requirement. The eventual limit will be either 17 or 28 ug/1.
• Annual flow meter calibration will be required by the end of July 2009. A check of the meter against the
staff gauge showed a difference of 1.2 %, well within the 10% tolerance.
• We note that long time Backup Operator Russell Wheeler recently retired. William Hux is assuming this
position, so please submit an operator designation form to the certification unit.

Copies of the enclosed report were mailed directly to the users of the town's collection
system.
Enclosed for your review are the required three copies of the Town of Weldon’s System
Performance Annual Report.
The Town s Collection system consists of five pumping stations and approximately 10 miles of
pipes connecting homes and businesses to the Wastewater Treatment Plant. The pipes range in
size from 8 to 12 inches in diameter. As is the case with the wastew'ater plant, heavy volumes of
wastewater produce problems for the collection system as well. We check problem areas in the
collection system as well as our pumping stations daily. As an added precaution, we have alarm
devices at each pumping station, which is audible, visible and capable of dialing preprogrammed
telephone numbers in case of emergency. During this 2008/2009 Annual Report year, the town
did not have any reportable sanitary sewer overflows.

The Town of Weldon owns and operates a Secondary Treatment Wastewater Plant designed to
treat 1.2 million gallons of wastewater a day. The treatment process includes a mechanical bar
screen, lor debris removal, pumping station, parallel biological treatment oxidation ditches,
parallel clarification, solids treatment with land application, final chlorination, de-chlorination,
and re-aeration processes. During this reporting year, we treated 358,065,000 million gallons of
wastewater and averaged treating 0.981 million gallons per day. As you can see, this is well
below our designed capacity. During this reporting year, we ran 9,048 tests of which we
contracted out 1,548 tests on the wastewater treated. The Town was out of compliance twice this
reporting period, one for exceeding our flow limit and one for exceeding our weekly fecal
coliform bacteria limit.

Mr. Crowder began sending split samples to two other laboratories to identify the problem. It
was eventually revealed that Microbac was using excess sulfite to dechlorinate samples before
running the BOD, and this was giving false high answers. Once that practice was stopped,
values returned to expected levels.
Myrl Nisely was in communication with ORC Donald Crowder concerning June exceedances in
the course of evaluating non-compliant test results from the Weldon WWTP. A problem was
immediately detected in early June when BOD values dramatically increased on the day after the
contract laboratory, Microbac, shifted testing from its Wilson facility to its Fayetteville
laboratory. Mr. Crowder contacted Mr. Nisely as soon as the problem was realized, who then
notified a DWQ Lab Certification auditor of the problem, as well. Values reported by the lab for
the next month (July) were also high, but the plant maintained compliance, though very near the
limit.

Your facility is currently monitoring for copper and/or zinc and the data indicate that the levels of copper/zinc in

the data are inconclusive as to copper and/or zinc’s role as a toxicity source, then the NPDES Permit will be reopened and
the metal limits specified above will be applied to the permit. The report is due nine months after the date of the second
WET Notice of Violation.
Failure to notify DWQ of your acceptance of a copper and/or zinc limit, failure to notify DWQ of your option
selection or failure to make acceptable demonstration to DWQ that copper and/or zinc are not causative effluent toxicants
within the stated time frames will result in reopening of the NPDES Permit to include copper and/or zinc numeric
limitations, as appropriate.
If the effluent is toxic, then we expect work to commence immediately with toxic effluent samples. Failure to
initiate work with toxic effluent samples during the study period is unacceptable and will be considered a failure to make
acceptable demonstration as cited above. We recommend a minimum of three separate sampling events during the nine
month period to definitively rule out copper and/or zinc as causative effluent toxicants.
Also note that the WET limit will remain in your NPDES permit regardless of whether metals are the source of
effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as sources of effluent toxicity will
determine whether NPDES Permit limits will be assigned for these parameters. You are responsible for initiating actions
to address these issues.
