The EDP Manager has determined no substantial deviation. [Section 32 -214(n)]. • Wekiva Study Area provisions [Section 32 -216(c)] do not apply to this legally existing C&D disposal facility prior to the effective date of May 1, 2009 [Section 32 -223]. • There is no record, or history, of violations or non-compliance to Orange County Code Chapter 32 [Section 32 -217(d)(5)]. • We accept Orange County EPD’s recommendation for permit renewal approval.

Existing Wekiva Study Area Protections • Low Recharge Area – Site specific geologic studies found 70 to 100 feet of clayey sediments under the site to protect the Floridan Aquifer. • Natural site geology attenuates leakage through the waste as shown by 15 years of clean Groundwater Quality Tests. • Groundwater monitoring wells are tested every 6 months. • C&D wastes are not a nutrient concern. • Stormwater Management System of ponds exceeds Wekiva Pollution Abatement standards. • Soil Cover the C&D reduces infiltration. • Ongoing Operational Best Management Practices. • Site will be a 220 acre open space or park at closure.
