rFEB ® 1994 BOOK 91 70 ARTIFICIAL WETLAND AT WEST REGIONAL WASTEWATER TREATMENT PLANT The Board reviewed the following memo dated February 2, 1994: DATE: February 2, 1994 TO: JAMES E. CHANDLER COUNTY ADMINISTRATOR FROM: TERRANCE G. PI DIRECTOR OF IIT SERVICES PREPARED ROBERT O. WISEMEN, P.E. AND STAFFED ENVIRONMENTAL ENGINEER BY: DEPARTMENT OF UTILITY SERVICES SUBJECT: ARTIFICIAL WETLAND AT WEST REGIONAL WWTP Due to the enforcement of the Indian River Lagoon Act and the Antidegradation Act, which disallows any additional pollutant discharge to all tributaries of Indian River, the Department of Environmental Protection (FDEP) has required and promoted a reuse program to be established in any County especially in a "Critical County" such as Indian River County. A Critical County is defined as a county which geographically is in close proximity of being affected by a salt water intrusion. This requirement has limited any discharge into the County canal system, which eventually flows into the Indian River. ANALYSIS: The outfall of the proposed wetland system is discharging to the adjacent canals, which presently are being used by Citrus Groves for sources of irrigation water. The FDEP in the process of issuing a permit for construction of said wetlands and has required the County.to perform a study to investigate alternative disposal systems. The alternative disposal system should include a residence reuse irrigation system. Even after the County Consultant submitted the Effluent Disposal Master Plan, which explains all alternative systems as well as recommended disposal systems based on economic reasons, the FDEP is still requiring the Reuse Feasibility Study to be conducted to satisfy the responsibility of enforcing the Indian River Lagoon Act and the Antidegradation Act. The County is seeking authorization to negotiate with the FDEP to reduce the requirements of the permitting process. In negotiating with the FDEP, Brown & Caldwell will be asked to accompany the County Staff to answer questions regarding the effluent disposal master plan. The consultant fee for assisting the County is estimated, not to exceed, $5,800.00 and the cost of the required study shall range from $30,000.00 to $55,000.00 RECOMMENDATION: The Utility Services Department recommends that the Indian River County Board of County Commissioners authorize the expenditure of $5,800.00 for Brown and Caldwell to accompany the County staff to negotiate with FDEP on the permitting requirements. Upon knowing the outcome of said negotiation, we recommend the authorization of the expenditure of, not to exceed, $55,000.00 for Brown and Caldwell to conduct the study immediately to meet the 30 day clock requirement governed by Chapter 17-3, FAC.
