In accordance with your permit change of ownership request received August 25, 2010, we are
forwarding herewith Permit No. WQ0002056, dated October 7, 2010, to Gatlin -Ramsey Mobile Home
Park for the continued operation of the subject wastewater treatment and wastewater irrigation facilities.
The Permittee has been changed from Edgar Earl Gatlin to Jerry and Johnnie Gatlin.
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
WQ0002056 is therefore being extended until February 28, 2015. Per your permit, a renewal application
must still be submitted six months in advance of the extended expiration date.
This permit shall be effective from the date of issuance until February 28, 2015, shall void Permit
No. WQ0002056 issued February 24, 2006, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements listed in Attachments A,
B, and C. Failure to establish an adequate system for collecting and maintaining the required operational
information shall result in future compliance problems.
Please pay special attention to the following items:
v Note that all monitoring reports are due by the last day of the month following the sampling
event, per Conditions IV.7. and IV.11.
> Attachment A contains effluent monitoring requirement. Effluent monitoring requirements
are unchanged from the previous permit.
