Prohibits: (1) a local unit; or (2) a water or wastewater utility; that is not under the jurisdiction of the Indiana utility regulatory commission (IURC) for the approval of rates and charges from charging or collecting from a property owner a capacity related fee or a tap fee either of which is established after June 30, 2022, and that includes contributions in aid of construction. Provides that if a local unit or a utility charges a property owner a capacity related fee or a tap fee that is established after June 30, 2022, and that is based, in whole or in part, on contributions in aid of construction, the property owner is entitled to request to meet with the local unit or the utility to review: (1) the engineering and financial analyses the fee was based on; and (2) if applicable, the ordinance adopting the fee. Requires a local unit or a utility to meet with a property owner for such a review not later than 30 days after receipt of the property owner's request. Provides that if a meeting and review does not result in a satisfactory resolution, the property owner may file with the IURC a petition challenging the fee. Provides that if the IURC determines the capacity related fee or tap fee is based in whole or in part on contributions in aid of construction, the IURC shall: (1) invalidate the fee; or (2) modify the fee to comply with these provisions. Amends the statute that provides an exemption from the requirement to connect to a regional sewer district's sewer system to a property owner whose septic tank soil absorption system was new at the time of installation as follows: (1) Provides that the local health department's designee or a qualified inspector (in addition to the local health department) may approve the property owner's septic tank soil absorption system at the time of installation. (2) Provides that the 10 year exemption is measured from the date of the required written determination of the local health department, the department's designee, or a qualified inspector that the property owner's septic tank soil absorption system is not failing. (Current law provides that the 10 year exemption is measured from the date the new septic tank soil absorption system was installed.) Defines "residential onsite sewage system" as the term is defined by the state department of health (department) in the department's rule concerning residential onsite sewage systems (department's rule). Changes instances of the term "residential septic system" in current law to the term "residential onsite sewage system". Prohibits a local health department from refusing an application for a permit for a residential onsite sewage system solely because the residential onsite sewage system has not been used previously in the jurisdiction of the local health department or is unfamiliar to the local health department, if the residential onsite sewage system has been approved for general use in Indiana by the department's technical review panel. Provides that if the local health department in one jurisdiction has issued a permit for a particular type of residential onsite sewage system, the local health department in another jurisdiction may not refuse to issue a permit for a residential onsite sewage system of that same type if: (1) a registered professional engineer; (2) a registered soil scientist; (3) a residential onsite sewage system installer; and (4) (if applicable) the designer of the residential onsite sewage system; approve of the use of that type of system in the second jurisdiction. Provides that if a registered professional engineer certifies: (1) that the location, design, proposed construction, and proposed installation of a planned residential onsite sewage system comply with the department's rule, a local health department may not disapprove an application for a permit for the residential onsite sewage system; (2) that the design, construction, installation, location, maintenance, and operation of an existing residential onsite sewage system comply with the department's rule, a local health department may not issue an order on the basis that the residential onsite sewage system is a failed system; and (3) that an existing residential onsite sewage system is not functioning properly but can be restored to proper functioning through repair, a local health department must allow the repair of the residential onsite sewage system to be made in accordance with the certification of the professional engineer. Provides that a local health department may not deny a permit for a residential onsite sewage system in a particular location on the grounds that the soil of the location is too heavily compacted if a registered soil scientist certifies that the soil can be made suitable for the residential onsite sewage system in not more than two years through the planting of plants that loosen and aerate the soil or through other means. Provides that after June 30, 2023, a local ordinance or a local health department may not impose residential onsite sewage system requirements, restrictions, or conditions that are more stringent than those of the department's rule. Requires a local health department to issue, in certain circumstances, a permit for a residential onsite sewage system not more than 30 business days after receiving the application for the permit. Effective July 1, 2023, voids a provision of the department's rule stating that the rule does not prohibit local ordinances from imposing requirements more stringent than the requirements of the department's rule. Changes population parameters used in an Indiana Code section concerning the installation of a residential onsite sewage system in fill soil, so as to reflect the population count determined under the 2020 decennial census. Amends the Indiana Code section governing the procedures for a proposal to amend or partially repeal a zoning ordinance to require a plan commission to vote on the proposal not later than 60 days after holding the public hearing on the proposal. Provides that a property owner whose property is incorporated into the territory of a municipal sanitation district (regardless of whether the property owner has filed a written remonstrance or an appeal with respect to the incorporation) is exempt from a requirement to connect to the district's sewer system and to discontinue use of a sewage disposal system on the property owner's property if: (1) the property owner's sewage disposal system: (A) was new at the time of installation; and (B) was approved in writing by the local health department, the department's designee, or a qualified inspector; and (2) the property owner obtains a written determination from the local health department, the department's designee, or a qualified inspector that the property owner's sewage disposal system is not failing. Provides that a property owner who qualifies for this exemption may not be required to connect to the district's sewer system for a period of 10 years beginning on the date of the required written determination of the local health department, the department's designee, or a qualified inspector that the property owner's septic tank soil absorption system is not failing. Provides that a property owner may apply for two five-year extensions of the exemption. Limits the total period during which a property may be exempt from the requirement to connect to a district's sewer system to not more than 20 years, regardless of ownership of the property. Sets forth certain time frames and requirements that apply to a property owner who seeks to claim the exemption. Provides that this exemption does not apply to a property owner whose property is incorporated into a district if: (1) the district has received approval from the Indiana finance authority before January 1, 2022, of a preliminary engineering report: (A) for a project to construct the sewer line to which the property owner's property is being required to connect; and (B) in connection with funding from the wastewater or drinking water revolving loan program; and (2) the timing and requirements for connection to the district's sewer system are the same for all property owners being required to connect to the district's sewer system under the terms of the project.
