Current through Reg. 50, No. 138; July 16, 2024
(1) An applicant for a wastewater treatment
				  facility permit shall provide a power outage contingency plan with the
				  submittal of the facility's application for a new permit, permit renewal, or
				  substantial permit revision. The power outage contingency plan shall describe
				  the general program and protocols to mitigate the impacts of power outages on
				  the facility's collection/transmission system and pump stations, including any
				  applicable mutual aid agreements. A copy of the power outage contingency plan,
				  including any updates or revisions, shall be submitted with subsequent facility
				  applications for permit renewal or substantial permit revision.
(2) Domestic wastewater facilities shall act
				  to prevent sanitary sewer overflows and underground pipe leaks for all
				  collection/transmission systems under control of the facility and shall meet
				  the requirements in this section for those systems.
(a) The facility permittee for a wastewater
				  treatment facility permit shall develop a pipe assessment, repair, and
				  replacement action plan, referred to hereafter in this sections as the
				  "collection system action plan" or "plan, " with at least a 5-year planning
				  horizon for all collection/transmission systems under the utility's control to
				  mitigate sanitary sewer overflows and underground pipe leaks to the extent
				  technically and economically feasible. The detail of the plan shall be
				  consistent with the complexity of the system based on the best professional
				  judgement of the individual signing the plan. Any portion of the plan requiring
				  "engineering, " as defined by Chapter 471, F.S., shall be certified by a
				  professional engineer registered in the State of Florida. An electronic summary
				  of the collection system action plan shall be submitted to the Department with
				  the facility permit application for any new permit, permit renewal, or
				  substantial permit revision. A copy of the plan or portions of the plan shall
				  be provided within 7 days of request by the Department. The collection system
				  action plan shall meet the following requirements:
1. The plan shall provide a deliberate,
				  proactive approach to evaluating or surveying the pipes, manholes, pump
				  stations, tanks, and other equipment for the collection/transmission systems
				  under the facility's control during the 5-year planning horizon period. This
				  shall be accomplished in an economically feasible manner. The collection system
				  action plan shall set goals for evaluating percentages of the
				  collection/transmission system annually through the use of one or more
				  investigative techniques such as camera inspections, smoke testing, data
				  analytics, flow isolation, focused electrode leak location, direct observation,
				  and sonar imaging, water chemistry, and solids analysis, or through use of flow
				  monitoring determine the amounts of infiltration, inflow, and leakages. The
				  plan shall set a minimum goal of performing basic evaluations for at least 25
				  percent of the collection/transmission system during the plan's five-year
				  planning horizon, unless the permittee demonstrates based on economic
				  feasibility, the age or performance of the collection/transmission system or
				  repairs, replacements, maintenance activities, and other upgrades conducted
				  therein that a lower percentage will achieve the requirements of subsection
				   62-600.410(6),
				  F.A.C., and the goals for infiltration, inflow, and leakages shall be below the
				  amounts considered excessive under Rule
				   62-604.500, F.A.C.
2. The plan shall be based on inflow and
				  infiltration studies and leakage surveys conducted by the facility permittee or
				  designee. When the initial inflow and infiltration studies and leakage surveys
				  indicate that inflow, infiltration, or leakage is excessive, then the plan
				  shall also be based on any follow-up sanitary sewer evaluation surveys. The
				  facility permittee may propose an alternative metric to these requirements
				  which the Department shall accept upon a demonstration by the facility
				  permittee that the alternative metric is at least as effective in
				  characterizing the collection/transmission system and determining the actions
				  needed to prevent sanitary sewer overflows.
3. The plan shall provide contact information
				  for the facility and utility of those responsible for implementing the
				  collection system action plan.
4.
				  The plan shall include a map and inventory of the collection/transmission
				  system. The plan for facilities with a permitted capacity of 1 million gallons
				  per day (mgd) or greater shall incorporate the use of a computerized geographic
				  information systems (GIS) map and an electronic maintenance management system
				  or other electronic inventory of the collection/transmission systems under
				  control of the facility, which shall include the following information to the
				  extent technically and economically practicable:
a. For each section of pipe, manholes, and
				  pump stations, a component identification tracking number, the location, length
				  of portion, size and diameter, type of pipe or construction, age, inspection
				  information, and maintenance information.
b. Any climatic and geologic data determined
				  necessary by the facility permittee to help identify appropriate maintenance
				  and repair actions, such as geologic and topographic information; hydrologic
				  information including seasonal high water table information prepared by the
				  facility permittee, United States Geological Survey or other governmental
				  entity; regional rainfall data collected by the facility permittee or other
				  governmental entity; and groundwater quality monitoring associated with the
				  collection/transmission system, if conducted.
c. Information regarding any
				  collection/transmission system flows, overflows, bypasses, verified odor
				  complaints, corrosion data, past inflow and infiltration analysis results, past
				  leakage surveys, population served, and industries served.
5. The plan shall include adaptive
				  maintenance and repair plans including general facility program and protocols
				  regarding routine maintenance, cleaning activities, and protocol for emergency
				  repairs.
6. The plan shall address
				  record keeping for all items in the collection system action plan.
7. The plan shall describe measures taken, if
				  any, for limiting the presence of fats, oils, grease, wet wipes, sand, and grit
				  to the collection/transmission system, as well as a root control
				  program.
8. The plan shall describe
				  measures taken, if any, such as any sewer ordinances or any programs
				  established by the applicable county or municipality in accordance with
				  sections  125.569 and
				   166.0481, F.S., to minimize
				  inflow and infiltration from individual service connections or sanitary sewer
				  laterals, including for single-family residences, to the extent addressing such
				  inflow and infiltration is determined necessary to prevent sanitary sewer
				  overflows and redressable within the authority of the facility
				  permittee.
9. The plan shall
				  identify, by no later than the first new permit, permit renewal, or substantial
				  permit revision application after December 21, 2025, all satellite collection
				  systems connected to the facility collection system including the name of each
				  satellite collection system, the ownership type of each identified satellite
				  collection system, a unique identifier number for each satellite collection
				  system, whether the satellite collection system is under the control of the
				  facility, and population served by the satellite collection system, The plan
				  shall describe the measures taken, if any, to require or encourage
				  owners/operators of satellite collection systems to minimize inflow and
				  infiltration from their satellite collection systems that cause or contribute
				  to sanitary sewer overflows in the facility's collection system.
10. The plan shall describe the resiliency of
				  the collection/transmission systems that considers sea-level rise and the
				  planned or completed flood mitigation and stormwater control actions, if any,
				  by the facility permittee or governmental entities that the facility permittee
				  identified as reducing the potential for inflow and infiltration into the
				  facility permittee's collection/transmission system.
