RE: 2018 Corrective Action Plan; City of Randleman,NC0025445
Enclosed,please fmd the Corrective Action Plan summarizing the actions taken and planned
actions in order to achieve compliance with the total lead limits at outfall 001 for the City of
Randleman Wastewater Treatment Plant. The plan is being provided in order to meet the NPDES
permit requirement of Part I,A.(5.) Schedule of Compliance(Outfall 001).
Should the City determine through additional diagnostics or consulting that it requires a
modification to the plan,requests will be made to the Division at least ninety(90)day before the
deadline,per the permit requirement.
Should you have any questions or require additional information,please do not hesitate to
contact me at the phone number listed below.
Thank you,

Corrective Action Plan for Compliance with Local Lead Limit
Permit Effective Date, August 1, 2017
RECEIVED/DENWDWR
AUG 022018
1) Background / Requirement Water Resources
Permitting Section
The City of Randleman received a renewal of NPDES Wastewater Plant discharge
permit number NC0025445, effective August 1, 2017. The renewed permit carried
new and changed requirements, including a lead limit with a compliance
schedule, Part 1, Section A (5), SCHEDULE OF COMPLAINCE (OUTFALL 001). This
Corrective Action Plan is being provided to the North Carolina Division of Water
Resources in response to item 1 of the compliance schedule: `By August 1, 2018,
the permittee shall submit to the Division of Water Resources a Corrective Action
Plan summarizing the actions or strategy to be taken to achieve compliance with
the local lead limits at outfall 001.Specific dates for completion or implementation
of each action shall be included.'
2) 2017-2018 Actions Taken
The City of Randleman began testing monthly for lead in August of 2017 as
required by the discharge permit. Additionally, the City conducted a series of
diagnostic activities, some of which are still ongoing. These actions are
summarized in Table 1 on pages 2-5.

The maximum and average concentrations for all
years post 2006 are well within the 0.016 mg/L
concentration limit for the WWTP effluent,and given
that potable water Lead and Copper testing are
targeted towards Tier 1 homes, the data do not
suggest that the single source of influent and
effluent lead values for the WWTP are a result of
home plumbing for the City of Randleman.

VI Consulted PERCS. Consulted with Deborah Gore and Vivien Ms. Gore consulted with a staff member with PWS
Zhong in December of 2017. Included experience, and passed along several
graphs and data summaries of lead suggestions, including inquiring about breaks, flow
values for reference. levels, and the use of corrosion control in the
system. As the City of Randleman purchases water
from Triad-Piedmont Water, they have inquired
with them regarding corrosion control, and is
awaiting an answer. No major line breaks were
reported that correlate with lead levels at the
WWTP.
City of Randleman, NC0025445, CAR Lead
Page 3 of 7

Ms. Gore reviewed the recent Headworks analysis,
adjusting the lead numbers to include the more
recent data, and determined that the plant should
not be in non-compliance based on available
data, as available data do not exceed theoretical
headworks capacity.
Additionally, Ms. Gore and Ms. Zhong suggested
increasing sample collection to attempt to trend
data. This was in progress at the time of the
response.
Ms. Gore also suggested that slip lining would be
an option should it be determined to be aging
collections system infrastructure, and
recommended continuing the targeted sampling
and testing in the CS.

Application would be required.
City of Randleman, NC0025445, CAR Lead
Page 4 of 7

3) Conclusions to Date:
a) There is a clear, identifiable and detectable level of lead at the influent of the
Randleman WWTP. This measured level, however is not consistent with non-
compliance of effluent based on the Headworks Analysis. It is possible that with
increased influent sampling, a more accurate picture of the incoming lead
concentrations may be obtained.
b) At this time, it appears unlikely that there is an unknown industrial contributor,
based on the industrial waste survey, and a general knowledge of the system by
City staff.
c) Although it appears unlikely that home plumbing would be the source, or more
accurately, the main source of lead in the incoming wastewater at the
Randleman WWTP plant, it cannot be ruled out completely without further
targeted analyses,especially given that the grab targeted manhole lead samples
indicated detectable levels only for lines serving domestic areas of the City.
d) The City's collections systems infrastructure is 6.6%ductile iron and steel. An aging
infrastructure cannot be ruled out as a contributing factor.
e) Additional collection systems sampling is required to confirm initial results of lead
sampling and further target the potential source areas.
4) Planned Actions and Timelines
The City plans to address the issue further by continued diagnostic testing,
consulting with qualified staff and contracting resources to effect corrective
actions based on the actions and items listed is Table 2.
