The proposed rules implement changes to chapter 381.0065, Florida Statutes, and incorporate other cost-saving measures recommended by the industry. The proposed changes have been reviewed and recommended by the Technical Review and Advisory Panel for onsite sewage treatment and disposal systems. The proposals address existing system reuse, definitions, system abandonment, permit expiration, performance-based treatment systems, estimated sewage flow, and septage storage facilities statewide. The proposed rules also address system repair in the Florida Keys.
