AB312-ASA2,15,3 19(2) Probable cause required for testing. Notwithstanding any conflicting
20provisions of this chapter, the department may not require the owner of a property
21to conduct testing under this chapter for the presence of PFAS without probable
22cause that the property had or currently has an amount of PFAS that is likely to
23exceed or result in the exceedance of any applicable promulgated standard under
24state or federal law. For purposes of this subsection, property does not include a
25property used for industrial purposes, including manufacturing. For purposes of this

1subsection, a basis for probable cause includes the reporting of a PFAS spill under
2this chapter or under section 304 of the federal Emergency Planning and Community
3Right-to-Know Act.
AB312-ASA2,15,7 4(3) Construction projects. Notwithstanding any conflicting provisions of this
5chapter, the department may not prevent, delay, or otherwise impede any

12intentional conduct, responsible for the original contamination.
AB312-ASA2,15,1413 (d) The department is specifically required under the federal Clean Water Act
14to prevent, delay, or otherwise impede the project.
AB312-ASA2,15,17 15(4) PFAS testing and enforcement on nonstate lands. If department staff or

17under this chapter for PFAS, all of the following shall apply:
AB312-ASA2,15,2318 (a) If the department, or an entity contracted by the department, seeks to
19collect voluntary samples from lands not owned by the state based on permission
20from the landowner, such permission shall be in writing, and the department shall

11or other authorized party to voluntarily take remedial action based on test results
12collected by the department.
AB312-ASA2,16,19 13(5) PFAS testing requests. The department shall, in a timely manner, respond
14to requests from any person to conduct PFAS testing on samples taken from the
15person's property if practicable and if funds are available to do so, if there is a
16reasonable belief that PFAS contamination may be present on the property, and if
17existing information such as public water supply testing data is not available. The
18department may contract with a 3rd party to respond to requests for testing under
19this subsection.
