Subject: Seep Management Amendment to Corrective Action Plan Conditional Approval &
Termination of Special Order by Consent S 19-006
Duke Energy Progress, LLC—Weatherspoon Steam Station
NPDES Permit NC0005363
Robeson County
Dear Ms. Bednarcik:
On August 29, 2022, Duke Energy Progress, LLC (Duke Energy) submitted a Seep Management Plan
Amendment to the proposed Corrective Action Plan(CAP)for the Weatherspoon Steam Station to
satisfy the terms of Section 2(b)(7) of Special Order by Consent(SOC) S 19-006. The Department of
Environmental Quality (DEQ)has reviewed this submittal and hereby provides its conditional approval
of the Seep Management Plan as an amendment to initial groundwater Corrective Action Plan(CAP)
documents prepared for the site and submitted in November 2015 and February 2016. This approval
has been provided as conditional because it is anticipated that an updated, comprehensive CAP will be
submitted for this site.
This conditional approval shall remain effective until an updated CAP for the Weatherspoon Steam
Station is approved, at which time the management of seeps will be regulated by its terms. As an
interim measure,this conditional approval requires Duke Energy to conduct semiannual monitoring for
the constituents listed in Table 1 of the SOC at SOC monitoring locations S-15 and S-16. Reporting of
the results of testing should continue to be submitted to DEQ via the email address used for the
reporting of SOC data [e-mail]).
This conditional approval concurs with the dispositioning of seeps as requested in the Seep
Characterization Report submitted in June 2022 for the Weatherspoon Steam Station; however,this
approval is also cognizant of the potential for changes in the circumstances of the seeps at the site
while it is in effect, and DEQ reserves its rights to require further monitoring of seeps should
circumstances warrant.
This conditional approval is sufficient to activate the SOC termination provision for the Weatherspoon
Steam Station found in Section 2(b)(8)of SOC S 19-006. As a result,the SOC shall terminate on
December 8, 2022 (30 days following the date of this letter).
