wastewater system shall be designed and operated with no discharge of wastes to surface waters, pursuant
to the application received July 14, 2009, and in conformity with the project plans, specifications, and
other supporting data subsequently filed and approved by the Department of Environment and Natural
Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until February 28, 2013, shall void Permit No.
WQ0032821 issued March 14, 2008 and shall be subject to the following specified conditions and
limitations:
L SCHEDULES
No later than six months prior to the expiration of this permit, the Permittee shall request renewal of
this permit on official Division forms. Upon receipt of the request, the Division will review the
adequacy of the facilities described therein, and if warranted, will renew the permit for such period of
