6 sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA); and
7 (ii) no higher than 10 parts per trillion (ppt) for perfluorononanoic
8 acid (PFNA), perfluorohexane sulfonate (PFHxS), and hexafluoropropylene
9 oxide dimer acid (HFPO-DA).
10 b. The commissioner shall establish a hazard index to address cumula-
11 tive exposure to multiple per- and polyfluoroalkyl substances. The
12 hazard index shall include but not be limited to perfluorononanoic acid
13 (PFNA), perfluorohexane sulfonate (PFHxS), hexafluoropropylene oxide
14 dimer acid (HFPO-DA), and perfluorobutane sulfonate (PFBS).
