AEGIS is a deadline service for plants that handle hazardous materials in California and New Jersey.
In California, 104 local agencies each set their own annual date. 26 of them do not use the March 1 state default, and none of them is required to remind you.
We went to all 104, one at a time.
Choose the state and the address where your chemicals are, and AEGIS shows the deadline and filing that apply to that facility, then reminds you before it arrives.
AEGIS does not file on your behalf and does not give legal advice.
You make your own filings.
