The Division of Water Resources(DWR of the Division)has reviewed your request to renew the
subject permit on behalf of the Permittee and hereby submit this draft for your review and
comment. Please review carefully to ensure your thorough understanding of permit information,
conditions,and requirements.
With this notification,the Division will solicit public comment on this draft permit by publishing
a notice in newspapers having circulation in the general Henderson County area,per EPA
requirements.Please provide your comments, if any,to me no later than 30 days after receiving
this draft permit.Your comments are welcome but are not required.
The Division understands that the Permittee has made no significant alterations to the treatment
system.We therefore have made only minimal changes to the permit by updating the permit text
and format.
eDMR Submittals: Please note that Federal regulations require electronic submittal of all
discharge monitoring reports(eDMRs)and program reports [See Special Condition A. (2.)].
Please note that if you fill out and submit to DWQ an electronic signature agreement,the
Division will no longer require you to submit DMR hardcopy as back-up to the eDMR.
We advise that Lewis Creek is listed as an impaired waterbody on the North Carolina 303(d)
Impaired Waters List,2018. Addressing impaired waters is a high priority with the Division; and
we will continue to evaluate. If DWR documents noncompliance with this permit's effluent
limits and stream impairment can be attributed to your facility,mitigative measures may be
required.
