The subject area of the proposed rulemaking is amendments to the District water use permitting rules in Chapter 40D-2, F.A.C., and Part B, Basis of Review For Water Use Permit Applications, of the Water Use Permit Information Manual regarding additional and enhanced conservation requirements for public supply, recreation and aesthetic water use permits. Some of the requirements for public supply permits within the Southern Water Use Caution Area (SWUCA) are proposed to apply also in areas not within the SWUCA. These include conservation rate structures, water billing requirements, water audits, wholesale permits and annual reports for public supply utilities. Some of the other District-wide proposed additions and enhancements include, limiting unaccounted water to a maximum of ten percent of production, requiring utilities to report conservation programs and initiatives within their service areas, information regarding reclaimed water generation, use and rate structure information, landscape codes, efficient irrigation of common areas and water conservation projects/programs. Also proposed are amendments to apply District-wide the SWUCA conservation requirements for recreation and aesthetic water use permits, including a phased elimination of irrigation of golf course roughs and adding identification and repair of system water losses. Other requirements may be developed during rulemaking.
