An existing 260 onsite sewage treatment and disposal system may be repaired if a 261 publicly owned or investor -owned sewage treatment system is not 262 available within 500 feet of the building sewer stub -out and if 263 system construction and operation standards can be met. This 264 paragraph does not require publicly owned or investor -owned 265 sewage treatment systems to accept anything other than domestic 266 wastewater. 267 1. A building located in an area zoned or used for 268 industrial or manufacturing purposes, or its equivalent, when 269 such building is served by an onsite sewage treatment and 270 disposal system, must not be occupied until the owner or tenant 271 has obtained written approval from the department. The 272 department may not grant approval when the proposed use of the 273 system is to dispose of toxic, hazardous, or industrial 274 wastewater or toxic or hazardous chemicals. 275 HB 287 2025 CODING: Words stricken are deletions; words underlined are additions. hb287-00 Page 12 of 26 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S 2. Each person who owns or operates a business or facility 276 in an area zoned or used for industrial or manufacturing 277 purposes, or its equivalent, or who owns or operates a business 278 that has the potential to generate toxic, hazardous, or 279 industrial wastewater or toxic or hazardous chemicals, and uses 280 an onsite sewage treatment and disposal system that is installed 281 on or after July 5, 1989, must obtain an annual system operating 282 permit from the department. A person who owns or operates a 283 business that uses an onsite sewage treatment and disposal 284 system that was installed and approved before July 5, 1989, does 285 not need to obtain a system operating permit. However, upon 286 change of ownership or tenancy, the new owner or operator must 287 notify the department of the change, and the new owner or 288 operator must obtain an annual system operating permit, 289 regardless of the date that the system was installed or 290 approved. 291 3. The department shall periodically review and evaluate 292 the continued use of onsite sewage treatment and disposal 293 systems in areas zoned or us ed for industrial or manufacturing 294 purposes, or its equivalent, and may require the collection and 295 analyses of samples from within and around such systems. If the 296 department finds that toxic or hazardous chemicals or toxic, 297 hazardous, or industrial wastewa ter have been or are being 298 disposed of through an onsite sewage treatment and disposal 299 system, the department shall initiate enforcement actions 300 HB 287 2025 CODING: Words stricken are deletions; words underlined are additions. hb287-00 Page 13 of 26 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S against the owner or tenant to ensure adequate cleanup, 301 treatment, and disposal. 302 (j) An onsite sewage treatme nt and disposal system 303 designed by a professional engineer registered in the state and 304 certified by such engineer as complying with performance 305 criteria adopted by the department must be approved by the 306 department subject to the following: 307 1. The performance criteria applicable to engineer -308 designed systems must be limited to those necessary to ensure 309 that such systems do not adversely affect the public health or 310 significantly degrade the groundwater or surface water. Such 311 performance criteria shall includ e consideration of the quality 312 of system effluent, the proposed total sewage flow per acre, 313 wastewater treatment capabilities of the natural or replaced 314 soil, water quality classification of the potential surface -315 water-receiving body, and the structural an d maintenance 316 viability of the system for the treatment of domestic 317 wastewater. However, performance criteria shall address only the 318 performance of a system and not a system's design. 319 2. A person electing to use an engineer -designed system 320 shall, upon completion of the system design, submit such design, 321 certified by a registered professional engineer, to the county 322 health department. The county health department may use an 323 outside consultant to review the engineer -designed system, with 324 the actual cost of such review to be borne by the applicant. 325 HB 287 2025 CODING: Words stricken are deletions; words underlined are additions. hb287-00 Page 14 of 26 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S Within 5 working days after receiving an engineer -designed 326 system permit application, the county health department shall 327 request additional information if the application is not 328 complete. Within 15 working days aft er receiving a complete 329 application for an engineer -designed system, the county health 330 department shall issue the permit or, if it determines that the 331 system does not comply with the performance criteria, shall 332 notify the applicant of that determination an d refer the 333 application to the department for a determination as to whether 334 the system should be approved, disapproved, or approved with 335 modification. The department engineer's determination shall 336 prevail over the action of the county health department. Th e 337 applicant shall be notified in writing of the department's 338 determination and of the applicant's rights to pursue a variance 339 or seek review under the provisions of chapter 120. 340 3. The owner of an engineer -designed performance -based 341 system must maintain a current maintenance service agreement 342 with a maintenance entity permitted by the department. The 343 maintenance entity shall inspect each system at least twice each 344 year and shall report quarterly to the department on the number 345 of systems inspected and ser viced. The reports may be submitted 346 electronically. 347 4. The property owner of an owner -occupied, single-family 348 residence may be approved and permitted by the department as a 349 maintenance entity for his or her own performance -based 350 HB 287 2025 CODING: Words stricken are deletions; words underlined are additions. hb287-00 Page 15 of 26 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S treatment system upon wri tten certification from the system 351 manufacturer's approved representative that the property owner 352 has received training on the proper installation and service of 353 the system. The maintenance service agreement must conspicuously 354 disclose that the property ow ner has the right to maintain his 355 or her own system and is exempt from contractor registration 356 requirements for performing construction, maintenance, or 357 repairs on the system but is subject to all permitting 358 requirements. 359 5. The property owner shall obta in a biennial system 360 operating permit from the department for each system. The 361 department shall inspect the system at least annually, or on 362 such periodic basis as the fee collected permits, and may 363 collect system-effluent samples if appropriate to determin e 364 compliance with the performance criteria. The fee for the 365 biennial operating permit shall be collected beginning with the 366 second year of system operation. 367 6. If an engineer-designed system fails to properly 368 function or fails to meet performance standar ds, the system 369 shall be re-engineered, if necessary, to bring the system into 370 compliance with the provisions of this section. 371 (k) An innovative system may be approved in conjunction 372 with an engineer-designed site-specific system that is certified 373 by the engineer to meet the performance -based criteria adopted 374 by the department. 375 HB 287 2025 CODING: Words stricken are deletions; words underlined are additions. hb287-00 Page 16 of 26 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S (l) For the Florida Keys, the department shall adopt a 376 special rule for the construction, installation, modification, 377 operation, repair, maintenance, and performance of onsite sew age 378 treatment and disposal systems which considers the unique soil 379 conditions and water table elevations, densities, and setback 380 requirements. On lots where a setback distance of 75 feet from 381 surface waters, saltmarsh, and buttonwood association habitat 382 areas cannot be met, an injection well, approved and permitted 383 by the department, may be used for disposal of effluent from 384 onsite sewage treatment and disposal systems. The following 385 additional requirements apply to onsite sewage treatment and 386 disposal systems in Monroe County: 387 1.
