       The Committee on Environment and Natural Resources (Martin)
       recommended the following:
       
    1         Senate Amendment 
    2  
    3         Delete lines 61 - 670
    4  and insert:
    5  permitting requirements. Except as provided in paragraph (a), a
    6  municipality or political subdivision of the state may not issue
    7  a building or plumbing permit for any building that requires the
    8  use of an onsite sewage treatment and disposal system unless the
    9  owner or builder has received a construction permit for such
   10  system from the department. A building or structure may not be
   11  occupied and a municipality, political subdivision, or any state
   12  or federal agency may not authorize occupancy until the
   13  department approves the final installation of the onsite sewage
   14  treatment and disposal system. A municipality or political
   15  subdivision of the state may not approve any change in occupancy
   16  or tenancy of a building that uses an onsite sewage treatment
   17  and disposal system until the department has reviewed the use of
   18  the system with the proposed change, approved the change, and
   19  amended the operating permit.
   20         (a)If the building or plumbing permit is for a single
   21  family residence that requires the use of an onsite sewage
   22  treatment and disposal system, a municipality or political
   23  subdivision of the state may not require the owner or builder to
   24  receive a construction permit from the department for such
   25  system as a condition of issuing the building or plumbing
   26  permit. The owner or builder of the single-family residence must
   27  provide to a municipality or political subdivision proof that
   28  the owner or builder submitted an application for the onsite
   29  sewage treatment and disposal system when applying for a
   30  building and plumbing permit.
   31         (b)(a) Subdivisions and lots in which each lot has a
   32  minimum area of at least one-half acre and either a minimum
   33  dimension of 100 feet or a mean of at least 100 feet of the side
   34  bordering the street and the distance formed by a line parallel
   35  to the side bordering the street drawn between the two most
   36  distant points of the remainder of the lot may be developed with
   37  a water system regulated under s. 381.0062 and onsite sewage
   38  treatment and disposal systems, provided the projected daily
   39  sewage flow does not exceed an average of 1,500 gallons per acre
   40  per day, and provided satisfactory drinking water can be
   41  obtained and all distance and setback, soil condition, water
   42  table elevation, and other related requirements of this section
   43  and rules adopted under this section can be met.
   44         (c)(b) Subdivisions and lots using a public water system as
   45  defined in s. 403.852 may use onsite sewage treatment and
   46  disposal systems, provided there are no more than four lots per
   47  acre, provided the projected daily sewage flow does not exceed
   48  an average of 2,500 gallons per acre per day, and provided that
   49  all distance and setback, soil condition, water table elevation,
   50  and other related requirements that are generally applicable to
   51  the use of onsite sewage treatment and disposal systems are met.
   52         (d)(c) Notwithstanding paragraphs (a) and (b) and (c), for
   53  subdivisions platted of record on or before October 1, 1991,
   54  when a developer or other appropriate entity has previously made
   55  or makes provisions, including financial assurances or other
   56  commitments, acceptable to the department, that a central water
   57  system will be installed by a regulated public utility based on
   58  a density formula, private potable wells may be used with onsite
   59  sewage treatment and disposal systems until the agreed-upon
   60  densities are reached. In a subdivision regulated by this
   61  paragraph, the average daily sewage flow may not exceed 2,500
   62  gallons per acre per day. This section does not affect the
   63  validity of existing prior agreements. After October 1, 1991,
   64  the exception provided under this paragraph is not available to
   65  a developer or other appropriate entity.
   66         (e)(d) Paragraphs (a) and (b) and (c) do not apply to any
   67  proposed residential subdivision with more than 50 lots or to
   68  any proposed commercial subdivision with more than 5 lots where
   69  a publicly owned or investor-owned sewage treatment system is
   70  available. This paragraph does not allow development of
   71  additional proposed subdivisions in order to evade the
   72  requirements of this paragraph.
   73         (f)(e) The department shall adopt rules relating to the
   74  location of onsite sewage treatment and disposal systems,
   75  including establishing setback distances, to prevent groundwater
   76  contamination and surface water contamination and to preserve
   77  the public health. The rules must consider conventional and
   78  enhanced nutrient-reducing onsite sewage treatment and disposal
   79  system designs, impaired or degraded water bodies, domestic
   80  wastewater and drinking water infrastructure, potable water
   81  sources, nonpotable wells, stormwater infrastructure, the onsite
   82  sewage treatment and disposal system remediation plans developed
   83  pursuant to s. 403.067(7)(a)9.b., nutrient pollution, and the
   84  recommendations of the onsite sewage treatment and disposal
   85  systems technical advisory committee established pursuant to
   86  former s. 381.00652. The rules must also allow a person to apply
   87  for and receive a variance from a rule requirement upon
   88  demonstration that the requirement would cause an undue hardship
   89  and granting the variance would not cause or contribute to the
   90  exceedance of a total maximum daily load.
   91         (g)(f) Onsite sewage treatment and disposal systems that
   92  are permitted before June 21, 2022, may not be placed closer
   93  than:
   94         1. Seventy-five feet from a private potable well.
   95         2. Two hundred feet from a public potable well serving a
   96  residential or nonresidential establishment having a total
   97  sewage flow of greater than 2,000 gallons per day.
   98         3. One hundred feet from a public potable well serving a
   99  residential or nonresidential establishment having a total
  100  sewage flow of less than or equal to 2,000 gallons per day.
  101         4. Fifty feet from any nonpotable well.
  102         5. Ten feet from any storm sewer pipe, to the maximum
  103  extent possible, but in no instance shall the setback be less
  104  than 5 feet.
  105         6. Seventy-five feet from the mean high-water line of a
  106  tidally influenced surface water body.
  107         7. Seventy-five feet from the mean annual flood line of a
  108  permanent nontidal surface water body.
  109         8. Fifteen feet from the design high-water line of
  110  retention areas, detention areas, or swales designed to contain
  111  standing or flowing water for less than 72 hours after a
  112  rainfall or the design high-water level of normally dry drainage
  113  ditches or normally dry individual lot stormwater retention
  114  areas.
  115         (h)(g) This section and rules adopted under this section
  116  relating to soil condition, water table elevation, distance, and
  117  other setback requirements must be equally applied to all lots,
  118  with the following exceptions:
  119         1. Any residential lot that was platted and recorded on or
  120  after January 1, 1972, or that is part of a residential
  121  subdivision that was approved by the appropriate permitting
  122  agency on or after January 1, 1972, and that was eligible for an
  123  onsite sewage treatment and disposal system construction permit
  124  on the date of such platting and recording or approval shall be
  125  eligible for an onsite sewage treatment and disposal system
  126  construction permit, regardless of when the application for a
  127  permit is made. If rules in effect at the time the permit
  128  application is filed cannot be met, residential lots platted and
  129  recorded or approved on or after January 1, 1972, shall, to the
  130  maximum extent possible, comply with the rules in effect at the
  131  time the permit application is filed. At a minimum, however,
  132  those residential lots platted and recorded or approved on or
  133  after January 1, 1972, but before January 1, 1983, shall comply
  134  with those rules in effect on January 1, 1983, and those
  135  residential lots platted and recorded or approved on or after
  136  January 1, 1983, shall comply with those rules in effect at the
  137  time of such platting and recording or approval. In determining
  138  the maximum extent of compliance with current rules that is
  139  possible, the department shall allow structures and
  140  appurtenances thereto which were authorized at the time such
  141  lots were platted and recorded or approved.
  142         2. Lots platted before 1972 are subject to a 50-foot
  143  minimum surface water setback and are not subject to lot size
  144  requirements. The projected daily flow for onsite sewage
  145  treatment and disposal systems for lots platted before 1972 may
  146  not exceed:
  147         a. Two thousand five hundred gallons per acre per day for
  148  lots served by public water systems as defined in s. 403.852.
  149         b. One thousand five hundred gallons per acre per day for
  150  lots served by water systems regulated under s. 381.0062.
  151         (i)1.(h)1. The department may grant variances in hardship
  152  cases which may be less restrictive than the provisions
  153  specified in this section. If a variance is granted and the
  154  onsite sewage treatment and disposal system construction permit
  155  has been issued, the variance may be transferred with the system
  156  construction permit, if the transferee files, within 60 days
  157  after the transfer of ownership, an amended construction permit
  158  application providing all corrected information and proof of
  159  ownership of the property and if the same variance would have
  160  been required for the new owner of the property as was
  161  originally granted to the original applicant for the variance. A
  162  fee is not associated with the processing of this supplemental
  163  information. A variance may not be granted under this section
  164  until the department is satisfied that:
  165         a. The hardship was not caused intentionally by the action
  166  of the applicant;
  167         b. A reasonable alternative, taking into consideration
  168  factors such as cost, does not exist for the treatment of the
  169  sewage; and
  170         c. The discharge from the onsite sewage treatment and
  171  disposal system will not adversely affect the health of the
  172  applicant or the public or significantly degrade the groundwater
  173  or surface waters.
  174  
  175  Where soil conditions, water table elevation, and setback
  176  provisions are determined by the department to be satisfactory,
  177  special consideration must be given to those lots platted before
  178  1972.
  179         2. The department shall appoint and staff a variance review
  180  and advisory committee, which shall meet monthly to recommend
  181  agency action on variance requests. The committee shall make its
  182  recommendations on variance requests at the meeting in which the
  183  application is scheduled for consideration, except for an
  184  extraordinary change in circumstances, the receipt of new
  185  information that raises new issues, or when the applicant
  186  requests an extension. The committee shall consider the criteria
  187  in subparagraph 1. in its recommended agency action on variance
  188  requests and shall also strive to allow property owners the full
  189  use of their land where possible.
  190         a. The committee is composed of the following:
  191         (I) The Secretary of Environmental Protection or his or her
  192  designee.
  193         (II) A representative from the county health departments.
  194         (III) A representative from the home building industry
  195  recommended by the Florida Home Builders Association.
  196         (IV) A representative from the septic tank industry
  197  recommended by the Florida Onsite Wastewater Association.
  198         (V) A representative from the Department of Health.
  199         (VI) A representative from the real estate industry who is
  200  also a developer in this state who develops lots using onsite
  201  sewage treatment and disposal systems, recommended by the
  202  Florida Association of Realtors.
  203         (VII) A representative from the engineering profession
  204  recommended by the Florida Engineering Society.
  205         b. Members shall be appointed for a term of 3 years, with
  206  such appointments being staggered so that the terms of no more
  207  than two members expire in any one year. Members shall serve
  208  without remuneration, but if requested, shall be reimbursed for
  209  per diem and travel expenses as provided in s. 112.061.
  210         3. The variance review and advisory committee is not
  211  responsible for reviewing water well permitting. However, the
  212  committee shall consider all requirements of law related to
  213  onsite sewage treatment and disposal systems when making
  214  recommendations on variance requests for onsite sewage treatment
  215  and disposal system permits.
  216         (j)(i) A construction permit may not be issued for an
  217  onsite sewage treatment and disposal system in any area zoned or
  218  used for industrial or manufacturing purposes, or its
  219  equivalent, where a publicly owned or investor-owned sewage
  220  treatment system is available, or where a likelihood exists that
  221  the system will receive toxic, hazardous, or industrial waste.
  222  An existing onsite sewage treatment and disposal system may be
  223  repaired if a publicly owned or investor-owned sewage treatment
  224  system is not available within 500 feet of the building sewer
  225  stub-out and if system construction and operation standards can
  226  be met. This paragraph does not require publicly owned or
  227  investor-owned sewage treatment systems to accept anything other
  228  than domestic wastewater.
  229         1. A building located in an area zoned or used for
  230  industrial or manufacturing purposes, or its equivalent, when
  231  such building is served by an onsite sewage treatment and
  232  disposal system, must not be occupied until the owner or tenant
  233  has obtained written approval from the department. The
  234  department may not grant approval when the proposed use of the
  235  system is to dispose of toxic, hazardous, or industrial
  236  wastewater or toxic or hazardous chemicals.
  237         2. Each person who owns or operates a business or facility
  238  in an area zoned or used for industrial or manufacturing
  239  purposes, or its equivalent, or who owns or operates a business
  240  that has the potential to generate toxic, hazardous, or
  241  industrial wastewater or toxic or hazardous chemicals, and uses
  242  an onsite sewage treatment and disposal system that is installed
  243  on or after July 5, 1989, must obtain an annual system operating
  244  permit from the department. A person who owns or operates a
  245  business that uses an onsite sewage treatment and disposal
  246  system that was installed and approved before July 5, 1989, does
  247  not need to obtain a system operating permit. However, upon
  248  change of ownership or tenancy, the new owner or operator must
  249  notify the department of the change, and the new owner or
  250  operator must obtain an annual system operating permit,
  251  regardless of the date that the system was installed or
  252  approved.
  253         3. The department shall periodically review and evaluate
  254  the continued use of onsite sewage treatment and disposal
  255  systems in areas zoned or used for industrial or manufacturing
  256  purposes, or its equivalent, and may require the collection and
  257  analyses of samples from within and around such systems. If the
  258  department finds that toxic or hazardous chemicals or toxic,
  259  hazardous, or industrial wastewater have been or are being
  260  disposed of through an onsite sewage treatment and disposal
  261  system, the department shall initiate enforcement actions
  262  against the owner or tenant to ensure adequate cleanup,
  263  treatment, and disposal.
  264         (k)(j) An onsite sewage treatment and disposal system
  265  designed by a professional engineer registered in the state and
  266  certified by such engineer as complying with performance
  267  criteria adopted by the department must be approved by the
  268  department subject to the following:
  269         1. The performance criteria applicable to engineer-designed
  270  systems must be limited to those necessary to ensure that such
  271  systems do not adversely affect the public health or
  272  significantly degrade the groundwater or surface water. Such
  273  performance criteria shall include consideration of the quality
  274  of system effluent, the proposed total sewage flow per acre,
  275  wastewater treatment capabilities of the natural or replaced
  276  soil, water quality classification of the potential surface
  277  water-receiving body, and the structural and maintenance
  278  viability of the system for the treatment of domestic
  279  wastewater. However, performance criteria shall address only the
  280  performance of a system and not a system’s design.
  281         2. A person electing to use an engineer-designed system
  282  shall, upon completion of the system design, submit such design,
  283  certified by a registered professional engineer, to the county
  284  health department. The county health department may use an
  285  outside consultant to review the engineer-designed system, with
  286  the actual cost of such review to be borne by the applicant.
  287  Within 5 working days after receiving an engineer-designed
  288  system permit application, the county health department shall
  289  request additional information if the application is not
  290  complete. Within 15 working days after receiving a complete
  291  application for an engineer-designed system, the county health
  292  department shall issue the permit or, if it determines that the
  293  system does not comply with the performance criteria, shall
  294  notify the applicant of that determination and refer the
  295  application to the department for a determination as to whether
  296  the system should be approved, disapproved, or approved with
  297  modification. The department engineer’s determination shall
  298  prevail over the action of the county health department. The
  299  applicant shall be notified in writing of the department’s
  300  determination and of the applicant’s rights to pursue a variance
  301  or seek review under the provisions of chapter 120.
  302         3. The owner of an engineer-designed performance-based
  303  system must maintain a current maintenance service agreement
  304  with a maintenance entity permitted by the department. The
  305  maintenance entity shall inspect each system at least twice each
  306  year and shall report quarterly to the department on the number
  307  of systems inspected and serviced. The reports may be submitted
  308  electronically.
  309         4. The property owner of an owner-occupied, single-family
  310  residence may be approved and permitted by the department as a
  311  maintenance entity for his or her own performance-based
  312  treatment system upon written certification from the system
  313  manufacturer’s approved representative that the property owner
  314  has received training on the proper installation and service of
  315  the system. The maintenance service agreement must conspicuously
  316  disclose that the property owner has the right to maintain his
  317  or her own system and is exempt from contractor registration
  318  requirements for performing construction, maintenance, or
  319  repairs on the system but is subject to all permitting
  320  requirements.
  321         5. The property owner shall obtain a biennial system
  322  operating permit from the department for each system. The
  323  department shall inspect the system at least annually, or on
  324  such periodic basis as the fee collected permits, and may
  325  collect system-effluent samples if appropriate to determine
  326  compliance with the performance criteria. The fee for the
  327  biennial operating permit shall be collected beginning with the
  328  second year of system operation.
  329         6. If an engineer-designed system fails to properly
  330  function or fails to meet performance standards, the system
  331  shall be re-engineered, if necessary, to bring the system into
  332  compliance with the provisions of this section.
  333         (l)(k) An innovative system may be approved in conjunction
  334  with an engineer-designed site-specific system that is certified
  335  by the engineer to meet the performance-based criteria adopted
  336  by the department.
  337         (m)(l) For the Florida Keys, the department shall adopt a
  338  special rule for the construction, installation, modification,
  339  operation, repair, maintenance, and performance of onsite sewage
  340  treatment and disposal systems which considers the unique soil
  341  conditions and water table elevations, densities, and setback
  342  requirements. On lots where a setback distance of 75 feet from
  343  surface waters, saltmarsh, and buttonwood association habitat
  344  areas cannot be met, an injection well, approved and permitted
  345  by the department, may be used for disposal of effluent from
  346  onsite sewage treatment and disposal systems. The following
  347  additional requirements apply to onsite sewage treatment and
  348  disposal systems in Monroe County:
  349         1. The county, each municipality, and those special
  350  districts established for the purpose of the collection,
  351  transmission, treatment, or disposal of sewage shall ensure, in
  352  accordance with the specific schedules adopted by the
  353  Administration Commission under s. 380.0552, the completion of
  354  onsite sewage treatment and disposal system upgrades to meet the
  355  requirements of this paragraph.
  356         2. Onsite sewage treatment and disposal systems must cease
  357  discharge by December 31, 2015, or must comply with department
  358  rules and provide the level of treatment which, on a permitted
  359  annual average basis, produces an effluent that contains no more
  360  than the following concentrations:
  361         a. Biochemical Oxygen Demand (CBOD5) of 10 mg/l.
  362         b. Suspended Solids of 10 mg/l.
  363         c. Total Nitrogen, expressed as N, of 10 mg/l or a
  364  reduction in nitrogen of at least 70 percent. A system that has
  365  been tested and certified to reduce nitrogen concentrations by
  366  at least 70 percent shall be deemed to be in compliance with
  367  this standard.
  368         d. Total Phosphorus, expressed as P, of 1 mg/l.
  369  
  370  In addition, onsite sewage treatment and disposal systems
  371  discharging to an injection well must provide basic disinfection
  372  as defined by department rule.
  373         3. In areas not scheduled to be served by a central
  374  sewerage system, onsite sewage treatment and disposal systems
  375  must, by December 31, 2015, comply with department rules and
  376  provide the level of treatment described in subparagraph 2.
  377         4. In areas scheduled to be served by a central sewerage
  378  system by December 31, 2015, if the property owner has paid a
  379  connection fee or assessment for connection to the central
  380  sewerage system, the property owner may install a holding tank
  381  with a high water alarm or an onsite sewage treatment and
  382  disposal system that meets the following minimum standards:
  383         a. The existing tanks must be pumped and inspected and
  384  certified as being watertight and free of defects in accordance
  385  with department rule; and
  386         b. A sand-lined drainfield or injection well in accordance
  387  with department rule must be installed.
  388         5. Onsite sewage treatment and disposal systems must be
  389  monitored for total nitrogen and total phosphorus concentrations
  390  as required by department rule.
  391         6. The department shall enforce proper installation,
  392  operation, and maintenance of onsite sewage treatment and
  393  disposal systems pursuant to this chapter, including ensuring
  394  that the appropriate level of treatment described in
  395  subparagraph 2. is met.
  396         7. The authority of a local government, including a special
  397  district, to mandate connection of an onsite sewage treatment
  398  and disposal system is governed by s. 4, chapter 99-395, Laws of
  399  Florida.
  400         8. Notwithstanding any other law, an onsite sewage
  401  treatment and disposal system installed after July 1, 2010, in
  402  unincorporated Monroe County, excluding special wastewater
  403  districts, that complies with the standards in subparagraph 2.
  404  is not required to connect to a central sewerage system until
  405  December 31, 2020.
  406         (n)(m) A product sold in the state for use in onsite sewage
  407  treatment and disposal systems may not contain any substance in
  408  concentrations or amounts that would interfere with or prevent
  409  the successful operation of such system, or that would cause
  410  discharges from such systems to violate applicable water quality
  411  standards. The department shall publish criteria for products
  412  known or expected to meet the conditions of this paragraph. If a
  413  product does not meet such criteria, such product may be sold if
  414  the manufacturer satisfactorily demonstrates to the department
  415  that the conditions of this paragraph are met.
  416         (o)(n) Evaluations for determining the seasonal high-water
  417  table elevations or the suitability of soils for the use of a
  418  new onsite sewage treatment and disposal system shall be
  419  performed by department personnel, professional engineers
  420  registered in the state, or such other persons with expertise,
  421  as defined by rule, in making such evaluations. Evaluations for
  422  determining mean annual flood lines shall be performed by those
  423  persons identified in paragraph (2)(l). The department shall
  424  accept evaluations submitted by professional engineers and such
  425  other persons as meet the expertise established by this section
  426  or by rule unless the department has a reasonable scientific
  427  basis for questioning the accuracy or completeness of the
  428  evaluation.
  429         (p)(o) An application for an onsite sewage treatment and
  430  disposal system permit shall be completed in full, signed by the
  431  owner or the owner’s authorized representative, or by a
  432  contractor licensed under chapter 489, and shall be accompanied
  433  by all required exhibits and fees. Specific documentation of
  434  property ownership is not required as a prerequisite to the
  435  review of an application or the issuance of a permit. The
  436  issuance of a permit does not constitute determination by the
  437  department of property ownership.
  438         (q)(p) The department may not require any form of
  439  subdivision analysis of property by an owner, developer, or
  440  subdivider before submission of an application for an onsite
  441  sewage treatment and disposal system.
  442         (r)(q) This section does not limit the power of a
  443  municipality or county to enforce other laws for the protection
  444  of the public health and safety.
  445         (s)(r) In the siting of onsite sewage treatment and
  446  disposal systems, including drainfields, shoulders, and slopes,
  447  guttering may not be required on single-family residential
  448  dwelling units for systems located greater than 5 feet from the
  449  roof drip line of the house. If guttering is used on residential
  450  dwelling units, the downspouts shall be directed away from the
  451  drainfield.
  452         (t)(s) Notwithstanding subparagraph (h)1. (g)1., onsite
  453  sewage treatment and disposal systems located in floodways of
  454  the Suwannee and Aucilla Rivers must adhere to the following
  455  requirements:
  456         1. The absorption surface of the drainfield may not be
  457  subject to flooding based on 10-year flood elevations. Provided,
  458  however, for lots or parcels created by the subdivision of land
  459  in accordance with applicable local government regulations
  460  before January 17, 1990, if an applicant cannot construct a
  461  drainfield system with the absorption surface of the drainfield
  462  at an elevation equal to or above 10-year flood elevation, the
  463  department shall issue a permit for an onsite sewage treatment
  464  and disposal system within the 10-year floodplain of rivers,
  465  streams, and other bodies of flowing water if all of the
  466  following criteria are met:
  467         a. The lot is at least one-half acre in size;
  468         b. The bottom of the drainfield is at least 36 inches above
  469  the 2-year flood elevation; and
  470         c. The applicant installs a waterless, incinerating, or
  471  organic waste composting toilet and a graywater system and
  472  drainfield in accordance with department rules; an aerobic
  473  treatment unit and drainfield in accordance with department
  474  rules; a system that is capable of reducing effluent nitrate by
  475  at least 50 percent in accordance with department rules; or a
  476  system other than a system using alternative drainfield
  477  materials in accordance with department rules. The United States
  478  Department of Agriculture Soil Conservation Service soil maps,
  479  State of Florida Water Management District data, and Federal
  480  Emergency Management Agency Flood Insurance maps are resources
  481  that shall be used to identify flood-prone areas.
  482         2. The use of fill or mounding to elevate a drainfield
  483  system out of the 10-year floodplain of rivers, streams, or
  484  other bodies of flowing water may not be permitted if such a
  485  system lies within a regulatory floodway of the Suwannee and
  486  Aucilla Rivers. In cases where the 10-year flood elevation does
  487  not coincide with the boundaries of the regulatory floodway, the
  488  regulatory floodway will be considered for the purposes of this
  489  subsection to extend at a minimum to the 10-year flood
  490  elevation.
  491         (u)1.(t)1. The owner of an aerobic treatment unit system
  492  shall maintain a current maintenance service agreement with an
  493  aerobic treatment unit maintenance entity permitted by the
  494  department. The maintenance entity shall inspect each aerobic
  495  treatment unit system at least twice each year and shall report
  496  quarterly to the department on the number of aerobic treatment
  497  unit systems inspected and serviced. The reports may be
  498  submitted electronically.
  499         2. The property owner of an owner-occupied, single-family
  500  residence may be approved and permitted by the department as a
  501  maintenance entity for his or her own aerobic treatment unit
  502  system upon written certification from the system manufacturer’s
  503  approved representative that the property owner has received
  504  training on the proper installation and service of the system.
  505  The maintenance entity service agreement must conspicuously
  506  disclose that the property owner has the right to maintain his
  507  or her own system and is exempt from contractor registration
  508  requirements for performing construction, maintenance, or
  509  repairs on the system but is subject to all permitting
  510  requirements.
  511         3. A septic tank contractor licensed under part III of
  512  chapter 489, if approved by the manufacturer, may not be denied
  513  access by the manufacturer to aerobic treatment unit system
  514  training or spare parts for maintenance entities. After the
  515  original warranty period, component parts for an aerobic
  516  treatment unit system may be replaced with parts that meet
  517  manufacturer’s specifications but are manufactured by others.
  518  The maintenance entity shall maintain documentation of the
  519  substitute part’s equivalency for 2 years and shall provide such
  520  documentation to the department upon request.
  521         4. The owner of an aerobic treatment unit system shall
  522  obtain a system operating permit from the department and allow
  523  the department to inspect during reasonable hours each aerobic
  524  treatment unit system at least annually, and such inspection may
  525  include collection and analysis of system-effluent samples for
  526  performance criteria established by rule of the department.
  527         (v)(u) The department may require the submission of
  528  detailed system construction plans that are prepared by a
  529  professional engineer registered in this state. The department
  530  shall establish by rule criteria for determining when such a
  531  submission is required.
  532         (w)(v) Any permit issued and approved by the department for
  533  the installation, modification, or repair of an onsite sewage
  534  treatment and disposal system shall transfer with the title to
  535  the property in a real estate transaction. A title may not be
  536  encumbered at the time of transfer by new permit requirements by
  537  a governmental entity for an onsite sewage treatment and
  538  disposal system which differ from the permitting requirements in
  539  effect at the time the system was permitted, modified, or
  540  repaired. An inspection of a system may not be mandated by a
  541  governmental entity at the point of sale in a real estate
  542  transaction. This paragraph does not affect a septic tank phase
  543  out deferral program implemented by a consolidated government as
  544  defined in s. 9, Art. VIII of the State Constitution of 1885.
  545         (x)(w) A governmental entity, including a municipality,
  546  county, or statutorily created commission, may not require an
  547  engineer-designed performance-based treatment system, excluding
  548  a passive engineer-designed performance-based treatment system,
  549  before the completion of the Florida Onsite Sewage Nitrogen
  550  Reduction Strategies Project. This paragraph does not apply to a
  551  governmental entity, including a municipality, county, or
  552  statutorily created commission, which adopted a local law,
  553  ordinance, or regulation on or before January 31, 2012.
  554  Notwithstanding this paragraph, an engineer-designed
  555  performance-based treatment system may be used to meet the
  556  requirements of the variance review and advisory committee
  557  recommendations.
  558         (y)1.(x)1. An onsite sewage treatment and disposal system
  559  is not considered abandoned if the system is disconnected from a
  560  structure that was made unusable or destroyed following a
  561  disaster and if the system was properly functioning at the time
  562  of disconnection and was not adversely affected by the disaster.
  563  The onsite sewage treatment and disposal system may be
  564  reconnected to a rebuilt structure if:
  565         a. The reconnection of the system is to the same type of
  566  structure which contains the same number of bedrooms or fewer,
  567  if the square footage of the structure is less than or equal to
  568  110 percent of the original square footage of the structure that
  569  existed before the disaster;
  570         b. The system is not a sanitary nuisance; and
  571         c. The system has not been altered without prior
  572  authorization.
  573         2. An onsite sewage treatment and disposal system that
  574  serves a property that is foreclosed upon is not considered
  575  abandoned.
  576         (z)(y) If an onsite sewage treatment and disposal system
  577  permittee receives, relies upon, and undertakes construction of
  578  a system based upon a validly issued construction permit under
  579  rules applicable at the time of construction but a change to a
  580  rule occurs within 5 years after the approval of the system for
  581  construction but before the final approval of the system, the
  582  rules applicable and in effect at the time of construction
  583  approval apply at the time of final approval if fundamental site
  584  conditions have not changed between the time of construction
  585  approval and final approval.
  586         (aa)(z) An existing-system inspection or evaluation and
  587  assessment, or a modification, replacement, or upgrade of an
  588  onsite sewage treatment and disposal system is not required for
  589  a remodeling addition or modification to a single-family home if
  590  a bedroom is not added. However, a remodeling addition or
  591  modification to a single-family home may not cover any part of
  592  the existing system or encroach upon a required setback or the
  593  unobstructed area. To determine if a setback or the unobstructed
  594  area is impacted, the local health department shall review and
  595  verify a floor plan and site plan of the proposed remodeling
  596  addition or modification to the home submitted by a remodeler
  597  which shows the location of the system, including the distance
  598  of the remodeling addition or modification to the home from the
  599  onsite sewage treatment and disposal system. The local health
  600  department may visit the site or otherwise determine the best
  601  means of verifying the information submitted. A verification of
  602  the location of a system is not an inspection or evaluation and
  603  assessment of the system. The review and verification must be
  604  completed within 7 business days after receipt by the local
  605  health department of a floor plan and site plan. If the review
  606  and verification is not completed within such time, the
  607  remodeling addition or modification to the single-family home,
  608  for the purposes of this paragraph, is approved.
  609         Section 2. Effective July 1, 2026, subsection (10) is added
  610  to section 381.0065, Florida Statutes, to read:
  611         381.0065 Onsite sewage treatment and disposal systems;
  612  regulation.—
  613         (10)ADOPTION OF NEW RULES.—Any new rules for the use and
  614  installation of onsite sewage treatment and disposal systems
  615  adopted by the
