How Rhode Island takes it
Rhode Island takes the Tier2 Submit file by email only, to dem.tier2@dem.ri.gov.
Rhode Island’s own pages name no filing fee. That is not the same as the state saying there is none, so if it matters to your budget, ring them and ask.
The file we build is the one this state works from.
The filing is due 1 March each year and covers the calendar year before it. Rhode Island does not pass it on for you — we checked. Filing closes the state’s copy only; your local committee and fire department each need their own from you.
Before you send it — what else Rhode Island asks for
Rhode Island wants your own copies sent to the municipal fire department and to your LEPC district chairperson as well — the email to DEM does not cover those. The Tier2 Submit program itself says at least three files must be attached for a Rhode Island facility, so your safety data sheets have to go in before you send it.
Does Rhode Island set its own limits?
Rhode Island keeps the federal numbers but adds a separate filing of its own. Meeting the federal rule is not the whole job here.
Rhode Island keeps the federal Tier II numbers, so the Tier II answer here is the federal answer — but there is a second, separate filing that catches far smaller sites. If you have even one employee and more than 2 gallons or 10 pounds of a hazardous substance, the Department of Labor and Training wants an annual Right-to-Know registration listing them by trade name and ingredient. There is no longer a fee for it. Tier II itself goes to DEM: use Tier2 Submit and email it to DEM.TIER2@dem.ri.gov.
The words we read
Two separate duties in Rhode Island, and only one of them is Tier II. Tier II: the thresholds are the federal ones. US EPA’s “State Tier II Reporting Requirements and Procedures” records the submission route for Rhode Island and no state threshold below the federal 10,000 lb / 500 lb-or-TPQ tests. We could not reach DEM’s own Tier II page on 2026-09-07, so that part rests on EPA’s compilation. The separate annual registration, run by the Department of Labor and Training rather than DEM, on the state’s own page, read 2026-09-07: “In compliance with Rhode Island General Law, Section 28-21, employers must complete the Hazardous Substance Right-to-Know Annual Registration Form and submit it to the RI Department of Labor and Training, Right-to-Know Unit.” It applies “If you have at least one employee, full or part-time, and you have hazardous substances greater than 2 gallons or 10 pounds, or a product containing at least 1%” of a listed carcinogen. You are exempt where “Employees are not exposed to hazardous substances greater than 10 pounds or two gallons stored and/or used on the premises or any carcinogens.” On cost: “Although there is no longer a registration fee, you are still required by law to comply with all the requirements listed below.” R.I. Gen. Laws § 28-21-2 and § 28-21-3, read 2026-09-08 on the General Assembly’s own server. § 28-21-2 defines a “designated substance” as one on the chapter’s list “provided they are in quantities exceeding two gallons (2 gals.) or 10 pounds (10 lbs.).” § 28-21-3 requires the employer to “obtain and maintain chemical identification lists” giving “the common and trade names of all designated substances present in the workplace in alphabetical order, cross referenced to their chemical names,” with a far lower trigger for carcinogens, mutagens and teratogens. So the 2-gallon / 10-pound figure is the statute’s, not an agency summary of it.
