Current through Reg. 50, No. 244; December 17, 2024

Section 62-699.310 - Classification and Staffing of Domestic Wastewater or Water Treatment Plants and Water Distribution Systems

This section applies to all domestic wastewater treatment plant permittees and to all suppliers of water except those who own or operate a transient non-community water system (TWS) using only ground water as a source of supply and serving only religious institutions, or businesses, other than public food service establishments as defined and regulated under Chapter 381, 500, or 509, F.S., and other than religious institutions with school or daycare services. Licensed operators are not required for TWSs using only ground water as a source of supply and serving only religious institutions, or businesses, other than public food service establishments and other than religious institutions with school or daycare services.

(1) Domestic wastewater treatment plant permittees and suppliers of water shall employ only persons appropriately licensed under Chapter 62-602, F.A.C., to be in on-site charge of the operation, supervision, or maintenance of a domestic wastewater or water treatment plant during any part of any day. Suppliers of water shall employ only persons appropriately licensed under Chapter 62-602, F.A.C., to be in onsite charge of any water distribution system operation or maintenance activity that may affect water quality or quantity and that is listed in Footnote 1 under the tables in subparagraphs 62-699.310(2)(f) 1. and 2., F.A.C.

(2) Permittees and suppliers of water shall employ licensed operators onsite at their domestic wastewater or water treatment plant(s) to fulfill the time and visit requirements specified in paragraphs (a) through (e), below. Suppliers of water shall employ licensed operators to staff their water distribution system as specified in paragraph (f), below.

(a) Classification and Staffing Requirements for Domestic Wastewater Treatment Plants Other than Those Discussed Separately in paragraphs (b) through (d), below. Refer to tables 1. through 4., below, and determine the classification and staffing requirements for each domestic wastewater treatment plant using the following two-step procedure: first determine the category of the plant and then, within that category, determine the classification and staffing requirements for the plant. Determine the plant category by identifying the highest category in tables 1. through 4., listing one or more of the plant's treatment processes, with Category I being the highest category and Category IV being the lowest category. Determine the plant classification and staffing requirements within the determined plant category by using the permitted capacity of the plant. Class A is the highest possible plant classification, and Class D is the lowest possible plant classification.

Determine the plant category by identifying the highest category in tables 1. through 5., listing one or more of the plant's category-determining treatment processes, with Category I being the highest category and Category V being the lowest category. In no case shall a treatment process that is installed and maintained by the Department under the Water Supply Restoration Program be considered in determining the plant category. Otherwise, for any plant that is part of a community water system (CWS), all of the plant's treatment processes shall be considered in determining the plant category, while for any plant that is part of a non-community water system (NCWS), only the plant's treatment processes that are necessary to meet primary drinking water standards, or disinfection requirements, applicable to the NCWS shall be considered in determining the plant category. Determine the plant classification and staffing requirements within the determined plant category by using the permitted maximum-day operating capacity of the plant. Class A is the highest possible plant classification, and Class D is the lowest possible plant classification.

(f) Classification and Staffing Requirements for Water Distribution Systems. Refer to tables 1. and 2., below, and determine the classification and staffing requirements for each water distribution system using the following two-step procedure: first determine the category of the distribution system and then, within that category, determine the classification and staffing requirements for the distribution system. Determine the distribution system category by using the highest classification of water treatment plant to which the distribution system is connected, with Class A being the highest plant classification and Class D being the lowest plant classification. Determine the distribution system classification and staffing requirements within the determined distribution system category by using the number of persons served directly by the distribution system, which excludes any persons served by any separately owned and operated wholesale or regulated consecutive system connected to the distribution system. Level 1 is the highest possible distribution system classification, and Level 4 is the lowest possible distribution system classification.
