THE FULL TEXT OF THE PROPOSED RULE IS:

 

62-550.200 Definitions for Public Water Systems.

For the purpose of this chapter and Chapters 62-555 and 62-560, F.A.C., the following words, phrases, or terms shall have the following meaning:

(1) through (12) No change.

(13) “CLEAN COMPLIANCE HISTORY” is, for the purposes of 40 C.F.R. Part 141, Subpart Y, which is incorporated by reference in Rule 62-550.830, F.A.C., a record of no MCL violations under 40 C.F.R. §141.63, as incorporated in subsection 62-550.310(5), F.A.C.; no monitoring violations under 40 C.F.R. §141.21, as incorporated in Rule 62-550.518, F.A.C., or 40 C.F.R. Part 141, Subpart Y; and no coliform treatment technique trigger exceedances or treatment technique violations under 40 C.F.R. Part 141, Subpart Y. (40 C.F.R. §141.2 revised as of July 1, 2014.) This subsection shall be effective on July 7, 2015.

(13) through (62) renumbered (14) through (63) No change.

(64) “LEVEL 1 ASSESSMENT” is an evaluation to identify the possible presence of sanitary defects, defects in distribution system coliform monitoring practices, and (when possible) the likely reason that the system triggered the assessment. It is conducted by the system operator or owner. Minimum elements include review and identification of atypical events that could affect distributed water quality or indicate that distributed water quality was impaired; changes in distribution system maintenance and operation that could affect distributed water quality (including water storage); source and treatment considerations that bear on distributed water quality, where appropriate (e.g., whether a ground water system is disinfected); existing water quality monitoring data; and inadequacies in sample sites, sampling protocol, and sample processing. The system must conduct the assessment consistent with any State directives that tailor specific assessment elements with respect to the size and type of the system and the size, type, and characteristics of the distribution system. (40 C.F.R. §141.2 revised as of July 1, 2014.) This subsection shall be effective on July 7, 2015.

(65) “LEVEL 2 ASSESSMENT” is an evaluation to identify the possible presence of sanitary defects, defects in distribution system coliform monitoring practices, and (when possible) the likely reason that the system triggered the assessment. A Level 2 assessment provides a more detailed examination of the system (including the system’s monitoring and operational practices) than does a Level 1 assessment through the use of more comprehensive investigation and review of available information, additional internal and external resources, and other relevant practices. It is conducted by an individual approved by the State, which may include the system operator. Minimum elements include review and identification of atypical events that could affect distributed water quality or indicate that distributed water quality was impaired; changes in distribution system maintenance and operation that could affect distributed water quality (including water storage); source and treatment considerations that bear on distributed water quality, where appropriate (e.g., whether a ground water system is disinfected); existing water quality monitoring data; and inadequacies in sample sites, sampling protocol, and sample processing. The system must conduct the assessment consistent with any State directives that tailor specific assessment elements with respect to the size and type of the system and the size, type, and characteristics of the distribution system. The system must comply with any expedited actions or additional actions required by the State in the case of an E. coli MCL violation. (40 C.F.R. §141.2 revised as of July 1, 2014.) This subsection shall be effective on July 7, 2015.

(63) through (71) renumbered (66) through (74) No change.

(75)(72) “NEW SYSTEM” means, for the purposes of capacity development, community water systems or non-transient non-community water systems being newly constructed; systems which do not currently meet the definition of a public water system under Rule 62-550.200, subsection 62-550.200(70), F.A.C., but which expand their infrastructure and thereby grow to become community water systems or non-transient non-community water systems; and transient non-community systems that expand their infrastructure and thereby grow to become community water systems or non-transient non-community water systems. Systems not currently public water systems under Rule 62-550.200, subsection 62-550.200(70), F.A.C., or systems that are transient non-community systems, and that add additional users and thereby become community water systems or non-transient non-community water systems without constructing any additional infrastructure are not “new systems” for purposes of capacity development. This subsection shall be effective on July 7, 2015.

(73) through (87) renumbered (76) through (90) No change.

(91) “SANITARY DEFECT” is a defect that could provide a pathway of entry for microbial contamination into the distribution system or that is indicative of a failure or imminent failure in a barrier that is already in place. (40 C.F.R. §141.2 revised as of July 1, 2014.) This subsection shall be effective on July 7, 2015.

(88) through (89) renumbered (92) through (93) No change.

(94) “SEASONAL SYSTEM” is a non-community water system that is not operated as a public water system on a year-round basis and starts up and shuts down at the beginning and end of each operating season. (40 C.F.R. §141.2 revised as of July 1, 2014.) This subsection shall be effective on July 7, 2015.

(90) through (119) renumbered (95) through (124) No change.
