Subject: Modified Permit No. WQ0020248
City of Sanford Big Buffalo Creek WWTP
Wastewater Treatment and Reclaimed Water
Utilization System
Lee County
SRF Project CS370432-04
In accordance with your permit major modification request received June 11, 2010, we are
forwarding herewith Permit No. WQ0020248, dated December 13, 2010, to the City of Sanford for the
construction and continued operation of the subject wastewater treatment and conjunctive reclaimed water
facilities.
The modifications to the subject permit are as follows:
Permit WQ0020247, issued February 13, 2002, has been incorporated into this permit in
order to unify all of the City of Sanford's reclaimed water permitted facilities under one
permit. Effective immediately, Permit WQ0020247 is rescinded, upon written request from
the City of Sanford received Nov. 10, 2010 to rescind Permit WQ0020247.
• This permit adds 0.67 acres of reclaimed water irrigation at the Big Buffalo Creek WWTP
(See Attachment B).
Please note that on August 5, 2009, Session Law 2009-406, entitled "An Act to Extend Certain
Government Approvals Affecting the Development of Real Property Within the State," was enacted by
the General Assembly and signed into law. The Act, known as the Permit Extension Act of 2009, extends
the expiration date of certain government approvals and permits. As part of the past legislative session
(S.L. 2010-177), HB 683 - Permit Extensions extended the Act by another year. Non -discharge permit
WQ0032821 is therefore being extended until September 30, 2015. Per your permit, a renewal
application must still be submitted six months in advance of the extended expiration date.
