Martin Kelly, Ph.D. Page 3 October 8,2008 involved in the development of this MFL, the FWC believes that the effects of this MFL will not .be significant on the current fish and wildlife resources of this river system and that this MFL is consistent with the agency's position regarding the establishment of MFLs in Florida spring systems. If any significant changes to this plan occur, we request the opportunity to review any such changes and comment accordingly. If you or your staff would like to coordinate hrther on the recornmendations contained in this letter, please contact Ron Mezich at 850-922-4330 or by email at ron.mezich@MyFWC.com.
