Foam and foam equipment manufacturing, installation, and testing entities: These entities would be required to implement appropriate containment, treatment, and disposal or storage measures to prevent discharges of the foam to the environment during testing of the foam or its equipment.
Public and private facilities that have installed fixed foam systems or that store fire fighting foam to be used for fire suppression: These facilities would need to determine the type of fire fighting foam used in fire suppression systems and ensure only testing or use for emergency fire fighting is conducted if the system contains class B fire fighting foam with PFAS. Any other use, training, or testing would be prohibited. These facilities may consider replacing Class B fire fighting foam containing PFAS with another product that does not contain PFAS.
7. Summary and preliminary comparison with any existing or proposed federal regulation that is intended to address the activities to be regulated by the proposed rule:
The federal Defense Authorization Act of 2020 specifies in section 323 that PFAS fire fighting foam may only be released for purposes of an emergency response. A non-emergency release of PFAS foam may be made for the purposes of testing of equipment or training of personnel, if complete containment, capture, and proper disposal mechanisms are in place to ensure no foam is released into the environment. It also requires the military to develop a fluorine-free foam specification by January 31, 2023, and sets a deadline for banning the use on military bases in the future. The law establishes guidelines for the proper disposal of fire fighting foam at military sites, and directs the military to develop guidance to address these issues.
State definitions of "environmental pollution" and "discharge" of a "hazardous substance" are not the same as the definition of a hazardous substance in the federal Superfund law and in some other states' laws. When discharged to the environment, PFAS compounds meet the definitions of a hazardous substance and/or environmental pollution under state statutes (s. 292.01, Wis. Stats.). There is no comparative federal law that prohibits the use or discharge of class B fire fighting foam that contains intentionally added PFAS. 8. Anticipated economic impact of implementing the rule (note if the rule is likely to have an economic impact on small businesses):
The anticipated economic impact of the emergency and permanent rules is moderate (less than $5,000,000 per year) based on the following assumptions:
- Minimal cost and time required for a person who discharges fire fighting foam to the environment to use existing department notification systems.
- Although not required, many entities and facilities may choose to replace class B fire fighting foam with one that does not contain PFAS. Based on legislative hearing testimony provided by the Wisconsin Fire Chief’s Association, the cost to collect and dispose of fire fighting foam and related wash waters from fire trucks and equipment was conservatively approximated to be $50 per gallon, and the cost of replacement foam was approximated to be $35 per gallon.
- The total amount of class B fire fighting foam containing PFAS in the state is currently unknown. However, the department will have an estimate of foam currently housed at fire departments from survey results expected in April 2020. A similar 2018 survey estimated over 36,000 gallons in Michigan. Because Michigan has a larger number of fire departments, the total quantity in Wisconsin is expected to be less.
The rule may have an economic impact on small businesses, as defined in s. 227.114 (1), Wis. Stats. The anticipated total economic impact of this rule (moderate impact) includes the estimated small business impact. The department will engage small business and business affiliated associations during the solicitation and development of the economic impact analysis period of this rule. 9. Anticipated number, month and locations of public hearings:
The department anticipates hosting informal public listening sessions to gather input throughout the rule drafting process for both the emergency and permanent rules, with opportunities for stakeholders around the state to submit comments in writing.
The department anticipates holding a public hearing for the emergency rule in the month of October 2020. The hearing will be conducted in Madison with opportunities for stakeholders around the state to connect to the Madison hearing via teleconference or video conference, and will allow for hearing comments to be submitted in writing.
The department will also hold a public hearing for the permanent rule in the month of December 2020. The hearing will be conducted in Madison with opportunities for stakeholders around the state to connect to the Madison hearing via teleconference or video conference, and will allow for hearing comments to be submitted in writing.
