RE: DWQ Project Number 07-0464
Olde Liberty Golf and Country Club, Franklin County, NC
Conditions for 401 Certification regarding Stormwater
Dear Ms. Lucas:
The purpose of this transmittal is to address conditions for 401 certification of Olde Liberty Golf
and Country Club regarding stormwater issues. The conditions regarding stormwater were
described under item 3 in letter dated August 13, 2007 from DWQ to Mr. Richard Wolf. Item 3
requires that bypass channels for level spreaders at discharge points 13, 18 and 19 be relocated to
avoid interception and short circuiting of diffuse flow through the riparian buffer.
Enclosed with this letter, please find one (1) copy of three (3) revised plan sheets showing
redesign of bypass channels and/or level spreader structures at discharge points 13, 18 and 19 to
meet requirements described under item 3. The revised plan sheets (revision 2) should replace
previously submitted sheets (revision 1). If you have any questions or require more information,
please contact me by phone at [phone] or by email at anice2(waol.com.
Sincerely,
Ale J. Nice, Ph.D., P.E.
