Amendment ASA2-AB312

This bill creates several new programs and requirements relating to PFAS, which is defined in the bill to mean any perfluoroalkyl or polyfluoroalkyl substance.

Municipal PFAS grant program

The bill requires the Department of Natural Resources to create a municipal PFAS grant program, which applies only to types of PFAS for which there is a state or federal standard, a public health recommendation from the Department of Health Services, or a health advisory issued by the federal Environmental Protection Agency. Under the bill, the municipal PFAS grant program provides all of the following grants:

1. Grants to municipalities (defined under current law as a city, town, village, county, county utility district, town sanitary district, public inland lake protection and rehabilitation district, or metropolitan sewage district) for PFAS testing at municipal water systems and municipal wastewater treatment facilities, or for reimbursement for such testing if performed at properties owned, leased, managed, or contracted for by municipalities and if there are promulgated standards for those types of PFAS.

2. Grants to nonmunicipal entities regulated as public or community water systems, distributed in equal shares up to $1,800, to test their drinking water supply for PFAS, if required to do so by DNR, or for reimbursement for such testing.

3. Grants to privately owned landfills, in equal shares up to $15,000, to test for the presence of PFAS in leachate.

4. Grants to municipalities to test for PFAS levels at municipally owned, leased, managed, or contracted locations where PFAS may be present, including testing for PFAS levels in leachate at landfills. If the property to be tested is not owned by the municipality, DNR may not issue a grant unless the property owner gives the municipality written consent to enter the property and conduct testing. These grants are not available to municipalities that receive a grant under this program to test for PFAS at municipal water systems and municipal wastewater treatment facilities. For these grants, DNR may require matching funds of up to 20 percent from the applicant.

5. Grants to municipalities and privately owned landfills to dispose of PFAS-containing biosolids or leachate at facilities that accept such biosolids or leachate or to purchase and install on-site treatment systems to address PFAS contained in biosolids or leachate. For these grants, DNR may require matching funds of up to 20 percent from the applicant and the grants may not be used for costs associated with landspreading.

6. Grants for capital costs or debt service, including for facility upgrades or new infrastructure, to municipalities that are small or disadvantaged or in which rates for water or wastewater utilities will increase by more than 20 percent as a direct result of steps taken to address PFAS contamination. When issuing these grants, DNR must give priority to projects that are necessary to address an exceedence of an applicable state or federal standard.

7. Grants to municipalities for capital costs or other costs related to PFAS that are not otherwise paid from the segregated environmental improvement fund, including costs for addressing landfills or other contaminated lands owned, leased, managed, or contracted for by municipalities or costs incurred by fire departments; grants to municipalities for the preparation and implementation of pollutant minimization plans; and grants to municipalities for costs incurred by public utilities or metropolitan sewerage districts for pretreatment or other PFAS reduction measures in certain circumstances. For these grants, DNR may require matching funds of up to 20 percent from the applicant.

For all of the grants provided under the municipal PFAS grant program, DNR may not require a grant recipient to take any action to address PFAS unless PFAS levels exceed any applicable standard under state or federal law. The bill also prohibits DNR from publicly disclosing the results of any PFAS testing conducted under this grant program unless DNR notifies the grant recipient at least 72 hours before publicly disclosing any test result, with certain exceptions.

Current law provides that whenever a state agency is authorized to provide state funds to any county, city, village, or town for any purpose, funds may also be granted by that agency to any federally recognized tribal governing body for the same purpose.

Innocent landowner grant program

The bill also requires DNR to create an innocent landowner grant program, which applies only to types of PFAS for which there is a state or federal standard, a public health recommendation from the Department of Health Services, or a health advisory issued by the federal Environmental Protection Agency.

Under the program, DNR may provide grants to an eligible person who owns, leases, manages, contracts for, or holds a department-issued solid waste facility license for property that is contaminated by PFAS. DNR may also provide grants to a person who is applying on behalf of multiple eligible persons that are located in the same geographic area, if the applicant will be the entity performing any authorized activities. Under the program, an “eligible person” is 1) a person that spread biosolids or wastewater residuals contaminated by PFAS in compliance with any applicable license or permit, 2) a person that owns land upon which biosolids or wastewater residuals contaminated by PFAS were spread in compliance with any applicable license or permit, 3) a fire department or municipality that responded to emergencies that required the use of PFAS or that conducted training for such emergencies in compliance with applicable federal regulations, 4) a solid waste disposal facility that accepted PFAS, 5) a person that owns, leases, manages, or contracts for property on which the PFAS contamination did not originate, and 6) any other person approved as an eligible person by the Joint Committee on Finance.

The total amount of grants awarded to each eligible person may not exceed $250,000 and DNR may require grant recipients to provide matching funds of not more than 5 percent of the grant amount.

Limitations on DNR actions relating to PFAS

Under the bill, DNR may not require the owner of a property to test for PFAS under the current spills law without probable cause that the property had or currently has an amount of PFAS that is likely to exceed or result in the exceedance of any applicable state or federal standard.

Under the bill, DNR may not prevent, delay, or otherwise impede any construction project or project of public works based on a presence of PFAS contamination unless DNR determines that 1) the project poses a substantial risk to public health or welfare, 2) there is a substantial risk that the project will create worsening environmental conditions, 3) the entity proposing to complete the project is, as a result of negligence or intentional conduct, responsible for the original contamination, or 4) DNR is specifically required under the federal Clean Water Act to prevent, delay, or otherwise impede the project. “Public works” is defined to mean the physical structures and facilities developed or acquired by a local unit of government or a federally recognized American Indian tribe or band in this state to provide services and functions for the benefit and use of the public, including water, sewerage, waste disposal, utilities, and transportation, and privately owned landfills that accept residential waste.

In addition, under the bill, if DNR seeks to collect samples from lands not owned by the state based on permission from the landowner, such permission must be in writing, and DNR must notify the landowner that such permission includes the authority to collect samples, to test those samples, and to publicly disclose the results of that testing. The landowner may revoke such permission at any time prior to the collection of samples. Under the bill, DNR also may not publicly disclose such PFAS testing results unless it notifies the landowner of the test results at least 72 hours before publicly disclosing them. In addition, DNR may not take any enforcement action against any person that meets the eligibility criteria for a grant under the innocent landowner grant program if the person grants DNR permission to remediate the property at DNR's expense. For persons that are not eligible under the innocent landowner grant program, the bill prohibits DNR from taking any enforcement action based on the results of any PFAS testing conducted on samples taken from lands not owned by the state unless PFAS levels exceed a federal or state standard. The bill also requires DNR, or a third-party contract by DNR, to respond in a timely manner to requests from any person to conduct PFAS testing on samples taken from the person's property if practicable and if funds are available to do so, if there is a reasonable belief that PFAS contamination may be present on the property, and if existing information such as public water supply testing data is not available.

The bill also requires DNR, in the 2023-25 fiscal biennium, to increase its voluntary PFAS testing activities.

Fire fighting foam

The bill requires DNR to survey or resurvey local fire departments about their use and possession of PFAS-containing fire fighting foam, send communications and information, and contract with a third party to voluntarily collect PFAS-containing firefighting foam.

Well compensation grant program

Under current law, an individual owner or renter of a contaminated private well, subject to eligibility requirements, may apply for a grant from DNR to cover a portion of the costs to treat the water, reconstruct the well, construct a new well, connect to a public water supply, or fill and seal the well. The bill provides that a grant for costs to treat the water may be used to cover the cost of a filtration device and up to two replacement filters.

In addition, under the bill, if DNR determines that a claimant who is applying for a grant under the well compensation grant program on the basis of PFAS contamination would be eligible for a grant under the innocent landowner grant program created under the bill, and funding under that program is available, DNR must refer the claimant's application to that program instead of processing it under the well compensation grant program. If the claimant is denied under the innocent landowner grant program, DNR must refer the claim back to the well compensation grant program.

Portable water treatment system pilot project

The bill requires DNR to contract with an entity to conduct a pilot project in which PFAS-contaminated surface water is partially or fully diverted to a portable treatment system and treated water is returned to the surface water. DNR and the entity must conduct tests to evaluate the success of the pilot project.

Remedial action at sites contaminated by PFAS

The bill allows DNR, or a contracted third party, to begin response and remedial actions, including site investigations, at any PFAS-contaminated site where a responsible party has not been identified or where the responsible party qualifies for a grant under the innocent landowner grant program. The bill directs DNR to prioritize response and remedial actions at sites that have the highest levels of PFAS contamination and sites with the greatest threats to public health or the environment because of PFAS.

Assistance for testing laboratories

The bill requires DNR and the Board of Regents of the University of Wisconsin System to enter into a memorandum of understanding to ensure that the state laboratory of hygiene provides guidance and other materials, conducts training, and provides assistance to laboratories in this state that are certified to test for contaminants other than PFAS in order for them to become certified to test for PFAS, and to assist laboratories certified to test for PFAS in this state to reduce their testing costs and shorten the timeline for receiving test results.

Under the bill, the Board of Regents, in coordination with DNR, may provide grants to laboratories in this state that are certified to test for PFAS, or that are seeking such certification, to assist with up to 40 percent of the costs of purchasing equipment necessary for testing for PFAS.

The bill requires the state laboratory of hygiene to prepare a report on these efforts and provide the report to the legislature.

PFAS studies and reporting

The bill requires DNR and the Board of Regents of the University of Wisconsin System to enter into a memorandum of understanding to 1) study and analyze the cost, feasibility, and effectiveness of different methods of treating PFAS before they are released into a water system or water body; 2) conduct a cost-benefit analysis of different options for disposing of biosolids or sludge that contains or may contain PFAS; 3) study and analyze the cost, feasibility, and effectiveness of different destruction and disposal methods for PFAS; 4) study and analyze the cost, feasibility, and effectiveness of different methods for remediating PFAS that leave the contaminated medium in place and methods that remove the contaminated medium; 5) study and analyze the migration of PFAS into the bay of Green Bay; 6) study and analyze the migration of PFAS into the Wisconsin and Mississippi Rivers and their tributaries; 7) create a comprehensive, interactive map showing all available PFAS testing data and, for each data point, whether it exceeds any applicable state or federal standard for PFAS; and 8) conduct any additional studies related to PFAS, as approved by the Joint Committee on Finance. Such data may not contain any personally identifiable information unless the entity to which the data applies is a municipal entity that is required to test and disclose its results under state law.

DNR reporting requirements

The bill requires DNR to report to the legislature once every six months for a period of three years to provide a detailed description of DNR's expenditures under the bill and a detailed description of DNR's progress in implementing the provisions of the bill.

Clean Water Fund Program and Safe Drinking Water Loan Program

Under current law, the Department of Administration and DNR administer the Safe Drinking Water Loan Program (SDWLP), which provides financial assistance to municipalities, and to the private owners of community water systems that serve municipalities, for projects that will help the municipalities comply with federal drinking water standards. DNR establishes a funding priority list for SDWLP projects, and DOA allocates funding for those projects. Also under current law, DNR administers the Clean Water Fund Program (CWFP), which provides financial assistance to municipalities for projects to control water pollution, such as sewage treatment plants.

Under the bill, if DNR, when ranking SDWLP or CWFP projects or determining an applicant's eligibility for assistance under those programs, considers whether an applicant that intends to extend service outside municipal boundaries because of water contamination is “small” or “disadvantaged,” DNR must determine the applicant to be small or disadvantaged if the area receiving the extended service would normally be determined to be small or disadvantaged, regardless of whether the existing service area would normally be determined to be small or disadvantaged.

Public water utility projects

Under current law, a public utility may not engage in certain construction, expansion, or other projects unless the Public Service Commission grants a certificate of authority (CA) for the proposed project. Under the bill, if a water public utility or a combined water and sewer public utility (water utility) fails to obtain a CA before commencing a project for which one is required, PSC may not investigate, impose a penalty against, or bring an action to enjoin the water utility if 1) the water utility undertook the project in response to a public health concern caused by PFAS, the presence of which was unknown to the water utility until shortly before it commenced the project and the water utility provides evidence showing that the utility has exceeded or is likely to exceed the applicable state or federal standard for that type of PFAS; 2) the water utility promptly notifies PSC of the work and, within 30 days after commencing the work, submits the appropriate application and supporting documentation to PSC; and 3) the total cost of the project is not greater than $2,000,000.

In the PSC administrative code, the bill adds an emergency resulting from water supply contamination to the circumstances under which PSC authorization is not necessary prior to a utility beginning necessary repair work. The current administrative code limits this to an emergency resulting from the failure of power supply or from fire, storm, or similar events.

Use of revenue for PFAS source reduction measures

The bill authorizes a municipal public utility or metropolitan sewerage district to use revenues from its water or sewerage services for up to half of the cost of pretreatment or other PFAS source reduction measures for an interconnected customer or other regular customer if the costs incurred are less than the costs of the upgrades otherwise required at the endpoint treatment facility and if the costs are approved by the governing body of the municipality or the metropolitan sewerage district.

Test wells for community water systems

Under rules promulgated by DNR relating to community water systems (a system for providing piped water for human consumption to the public and that serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents), DNR must pre-approve any test wells that will be converted into permanent wells and any test wells that will pump at least 70 gallons per minute for more than 72 hours. DNR rules require test wells to be drilled for permanent wells for community water systems to determine geologic formation information and water quality and quantity data. DNR rules also allow DNR to designate special well casing depth areas within which wells must be drilled to a greater depth and meet other requirements to avoid contamination.

This bill provides that test wells for community water systems must also be approved by DNR if they are located in special well casing depth areas that have been designated based in whole or in part on the presence of PFAS.

The people of the state of Wisconsin, represented in senate and assembly, do enact as follows:
