Plain English Breakdown

PFAS Testing and Remediation

This act requires the state department to test drinking water for PFAS substances annually and mandates remedial actions if contamination is found.

What This Bill Does

  • Requires the state department to test all public water systems in Alaska for PFAS substances at least once a year.
  • Specifies that when PFAS substances are released near a water supply, the department must test drinking water from that supply and provide alternative water sources if contamination levels exceed set limits.
  • Establishes specific cutoff concentrations for certain PFAS substances to determine safe levels of contamination in drinking water.
  • Requires facilities using thermal remediation methods to obtain a permit from the department under federal Clean Air Act regulations.

Who It Names or Affects

  • Public water systems in Alaska
  • Facilities using thermal remediation for PFAS contamination

Terms To Know

PFAS
Perfluoroalkyl and polyfluoroalkyl substances, a group of man-made chemicals used in various industries.
Thermal remediation
A process that uses heat to remove or destroy contaminants from soil or groundwater.

Limits and Unknowns

  • The bill does not specify the exact health-based values for PFAS substances, leaving these to be established by regulation.
  • Effective date of January 1, 2027, means there may be a delay before all requirements are implemented.

A BILL

FOR AN ACT ENTITLED

"An Act relating to perfluoroalkyl and polyfluoroalkyl substances; relating to thermal 1
remediation of perfluoroalkyl and polyfluoroalkyl substance contamination; and 2
providing for an effective date." 3
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF ALASKA: 4
* Section 1. AS 46.03 is amended by adding new sections to read: 5
Article 6A. Perfluoroalkyl and Polyfluoroalkyl Substances. 6
Sec. 46.03.345. Testing; drinking water. (a) The department shall test the 7
drinking water from all public water systems located in the state at least annually for 8
the presence of perfluoroalkyl substances and polyfluoroalkyl substances. 9
(b) When a perfluoroalkyl substance or polyfluoroalkyl substance is released 10
in the area of a water supply located in the state, the department shall test all drinking 11
water from the water supply for perfluoroalkyl substances and polyfluoroalkyl 12
substances. If a test conducted under this subsection detects a perfluoroalkyl substance 13
or polyfluoroalkyl substance at a level equal to or greater than the limit described in 14
34-LS0833\A
HB 235 -2- HB0235a
New Text Underlined [DELETED TEXT BRACKETED]

(c) of this section, the department shall provide each person who routinely uses the 1
tested drinking water, at no cost to the person, a source of drinking water containing 2
levels of perfluoroalkyl substances and polyfluoroalkyl substances lower than the 3
limits described in (c) of this section. 4
(c) For purposes of this section, 5
(1) the limit of perfluoroalkyl substance or polyfluoroalkyl substance 6
contamination in water is the lesser of 7
(A) the limit established by the department in regulation; or 8
(B) the following limits: 9
SUBSTANCE CUTOFF CONCENTRATION 10
perfluorooctanoic acid 4 parts per trillion 11
perfluorooctanesulfonic acid 4 parts per trillion 12
perfluorononanoic acid 10 parts per trillion 13
perfluorohexanesulfonic acid 10 parts per trillion 14
hexafluoropropylene oxide dimer acid 10 parts per trillion 15
mixture containing two or more of the following: 1 hazard index 16
perfluorononanoic acid, perfluorohexanesulfonic acid, 17
hexafluoropropylene oxide dimer acid, and 18
perfluorobutanesulfonic acid; 19
(2) the hazard index is the sum of the quotients calculated for each 20
substance by dividing the measured concentration of the substance in drinking 21
water by the health-based value associated with the substance expressed in the 22
same units as the measured concentration using 23
(A) the health-based values established by the department in 24
regulation; or 25
(B) the following health-based values: 26
SUBSTANCE HEALTH-BASED VALUE 27
perfluorononanoic acid 10 parts per trillion 28
perfluorohexanesulfonic acid 10 parts per trillion 29

Sec. 46.03.350. Liability for drinking water and drinking water testing. (a) 1
A person who causes a release of a perfluoroalkyl substance or polyfluoroalkyl 2
substance is liable for the costs of providing drinking water and drinking water testing 3
under AS 46.03.345 if the person failed to comply with any applicable laws, 4
regulations, or manufacturer instructions regarding the use and disposal of the 5
substance. 6
(b) If a person who causes a release of a product containing a perfluoroalkyl 7
substance or polyfluoroalkyl substance complied with all applicable laws, regulations, 8
and manufacturer instructions in the use and disposal of the product, the manufacturer 9
of the product is 10
(1) liable for the costs of providing drinking water and drinking water 11
testing under AS 46.03.345; and 12
(2) jointly and severally liable for any other liability under this chapter, 13
AS 46.08, AS 46.09, or any other state law related to the release of the product. 14
(c) The liability of a person for costs under this section is in addition to other 15
liability under this chapter, AS 46.08, AS 46.09, or other state law for a release of a 16
perfluoroalkyl substance or polyfluoroalkyl substance. 17
Sec. 46.03.355. Thermal remediation permit. A facility that thermally 18
remediates a perfluoroalkyl substance or polyfluoroalkyl substance contamination 19
must have a permit from the department issued under 42 U.S.C. 7661 - 7661f (Clean 20
Air Act, secs. 501 - 507) authorizing the remediation. The department may not issue a 21
permit or allow a facility to retain a permit issued under this section if the department 22
determines that the remediation will result in the release of more than a minimal 23
amount of an airborne compound with a carbon-fluorine bond detectable through 24
source testing. Source testing under this section must include testing of all compounds 25
with a carbon-fluorine bond for which the United States Environmental Protection 26
Agency has approved a testing methodology. 27
Sec. 46.03.359. Definitions. In AS 46.03.345 - 46.03.359, "perfluoroalkyl 28
substance" and "polyfluoroalkyl substance" include 29

read: 8
APPLICABILITY; RETROACTIVITY. AS 46.03.350, added by sec. 1 of this Act, 9
