Dear Mr. Crisp:
In accordance with your request received April 4, 2007, we are forwarding herewith a corrected
Page 6 for Permit No, WQ0020409, dated March 22, 2007. The purpose of this correction is to remove
the permit condition that limits irrigation at the Town of Zebulon's Five County Stadium. This permit
condition was removed during a permit modification issued January 12, 2005, but was inadvertently
included in the permit issued March 22, 2007. Please replace Page 6 of the permit with the corrected
Page 6 that is enclosed.
6187.
If you need additional information concerning this matter, please contact Lori Veal at (919) 715-

shall be irrigated onto the irrigation area.
Should the limit for fecal coliform (daily maximum concentration of 25 per 100 ml) or turbidity
(instantaneous maximum of 10 NTU) be exceeded, all wastewater shall be handled in one of three
ways, until the levels have stabilized below these maximum levels. The City of Raleigh may
further treat the wastewater to bring it into compliance with reclaimed water standards without
returning the water to the facility's headworks, may reroute it to the headworks of the Little
