Subject: RE: Mayo SW coverage for Monofill
Thank you, Lori. I agree, with a couple clarifications:
There is no need to submit a renewal application for NCG12 unless directed to do so by the Division as per 15A NCAC
O2H .0127(e). We do not plan to require any applications for General Permits expiring this year.
Once a request is in-house for a modification to the Mayo Electric Plant permit to include the Monofill, the Division will
consider the timing needed to complete the modification to the ISW permit. If the timing is such that it cannot be
concluded before NCG12 expires, we will ensure that coverage under General Permit NCG12 will not lapse before the
modified individual permit can be issued. One option to accomplish this beyond October 31, 2017 if needed would be to
reissue a new NCG12 COC to Mayo Monofill for an abbreviated amount of time under the renewed General Permit, and
then rescind that COC upon issuance of the individual permit that covers these discharges. DEMLR will have to
determine the best course of action based on timing and staff resources.
This process will require a major modification, which will mean a public notice period for the modified individual
stormwater permit. There is a reasonable chance a public hearing will result, but that will not be determined until
further into the process.
If you have any other questions, please let us know.
Best regards,
Bethany

Subject: Mayo SW coverage for Monofill

Bethany,
I just wanted to recap our discussion on the steps needed as Mayo's general permit for Monofill SW coverage will expire
in October.
The Mayo Station would like to pursue a modification of its existing NPDES ISW permit to include the three monofill
outfalls currently permitted under general permit NCG12. I understand and you concur, that a general permit does not
require a renewal application 180 days in advance of its expiration and that the Mayo NCG 12 permit will be
administratively extended after October if the modifications to the NPDES ISW permit are not complete. I also
understand that this work will constitute a major modification of our NPDES ISW permit and a public notice and hearing
will be required. Finally, based on the steps outlined here the Mayo monofill will at no time be without SW coverage as
we work toward modifying our NPDES ISW permit. Thank you for your time yesterday.
