Notices by filing month
Counts cover the notices on this site, which begin January 2, 2018. A notice is an allegation, not a finding.
What past notices came to, all filing years
Counted from the Attorney General's yearly settlement and judgment files, for every filing year on this site. Other figures on this page are counted another way and cover fewer years, so the numbers differ: they come from each notice's own page on the state's site, for the filing years this site has finished checking.
- Notices alleging this chemical that appear in the state's yearly files
- 1 of 3
- Median payment per notice, adding up every settlement and judgment on it
- Fewer than 10 resolved notices (1 so far), too few to show this figure
Source: the Attorney General's yearly settlement and judgment files, for notices filed in 2024, read November 14, 2026. These are counts of past notices. They are not a prediction for any company or notice, and they are not legal advice. Recent notices are still being resolved. A settlement is not an admission of liability and not a finding that a violation occurred. How these figures are built.
