S7T0FtMWATER PERMITTING
As discussed during a phone conversation between Mr. Shannon Langley of Duke Energy
(Duke) and Dave Parnell of the Raleigh Regional Office on May 2, 2014, Duke hereby requests
modification of the subject permit to allow for collection of the initial storm water samples
analysis associated with the subject permit.
Duke is making this request because, as of the date of this letter, no coal combustion residuals
have been placed into the monofill. In accordance with the terms of the subject permit, storm
water samples associated with industrial activity are required to be sampled between January 1,
2014 and June 30, 2014 and every six month period thereafter. With no industrial activity to
date, we have been unable to obtain these samples to date. Additionally, prior to operation, Duke
must obtain a certificate to operate the monofill from the North Carolina Division of Waste
Management (NCDWM). Final submittals in order to obtain this certificate are being completed
at this time. Currently, we expect to obtain this certificate in June but that is subject to change
based on the review of NCDWM staff. Modifying the first sampling period to be between July
1, 2014 and December 31, 2014 would ensure a sample associated with industrial activity could
be obtained after the commissioning of the monofill.
As discussed, the Mayo monofill is necessary to facilitate the removal of a wastewater discharge to
Mayo Reservoir in accordance with the Special Order by Consent between Duke Energy Progress
and the North Carolina Environmental Management Commission EMC SOC WQ S10-012. If there
are any questions regarding this request, please contact Shannon Langley at [phone].
