To Ms. Roten:
The Division of Water Resources(DWR or the Division)received your application to renew the
subject permit on April 13,2021.Please review the attached renewal draft carefully to ensure
your understanding of its limits and monitoring conditions,and to correct errors,if any.
Concurrent with this notification,the Division will solicit public comment on this draft by

NCDEQ/DWR/NPDES no later than July 25,2021 (approximately 30 days after receiving
this document). We welcome your written comments,but they are not mandatory.
The Division understands that,since last renewal,the Town of Lansing(Lansing)has made no
significant alterations to treatment systems or processes.Therefore,we have made only minimal
changes to the permit for this renewal as:
1. added requirement to notify WSRO and the Central Office 30 days in advance
of intent to embark on flow Phase 2 of this permit[see Supplement to Permit
Cover Sheet].
2. updated WWTP text RE treatment Grade I Biological(first phase)
and Grade II Biological(second Phase)

4. updated text for electronic reporting requirements. [Section A. (3.)]
5. updated Lansing's site map.
Please note that the receiving stream,Big Horse Creek, is classified High Quality Water(HQW).
Protecting HQW waters is a high priority with the Division,and we will continue to evaluate instream
water quality. If Lansing's effluent data indicate noncompliance with permit monitoring and limits,and
stream impairment can be attributed to your facility, DWR may require you to initiate mitigative
measures.
