What Rhode Island asks for

Each point is followed by the words of the state's own page.

How to file

Build the report in EPA's Tier2 Submit and send it by email only, to dem.tier2@dem.ri.gov.

“The Tier II annual inventory form must be sent by email only to dem.tier2@dem.ri.gov .” source

“The Tier2 Emergency and Hazardous Chemical Inventory forms must be submitted in an electronic format developed by the U. S. Environmental Protection Agency.” source

Deadline

Due by March 1 each year.

“Submission of the Tier II Facilities Emergency and Hazardous Chemical Inventory must be submitted by March 1 of each year” source

State thresholds

Rhode Island uses the federal thresholds: 500 pounds or the threshold planning quantity, whichever is lower, for extremely hazardous substances; 10,000 pounds for other hazardous chemicals that need an SDS.

“For Extremely Hazardous Substances (EHS) designated under Section 302 of Title III, the reporting threshold is 500 pounds (227 kg) or the Threshold Planning Quantity (TPQ), whichever is lower.” source

“For all other hazardous chemicals for which facilities are required to have or prepare an SDS, the minimum reporting threshold is 10,000 pounds (4,540 kg).” source

Who gets the report

Copies also go to the local fire department and, by email by March 1, to the chairperson of the facility's LEPC district, listed on the DEM page.

“Copies of the Tier II annual inventory form must also be sent to:” source

“To comply with annual Tier II reporting requirements with respect to the LEPCs, please submit forms electronically to the chairperson for your district using the email address listed below by March 1.” source

State-specific rule

DEM reviews submissions for accuracy and refers Section 312 violations to EPA for penalties.

“All violations of Section 312 reporting requirements shall be referred to the United States Environmental Protection Agency (USEPA) for enforcement of penalties under this statute.” source

The federal rule underneath

EPCRA section 312 applies to a facility that the OSHA HazCom Standard requires to keep an SDS for a hazardous chemical present at any one time at or above 10,000 lb, or at or above 500 lb or its threshold planning quantity, whichever is lower, for an extremely hazardous substance (40 CFR 370.10(a)). The 10,000 lb figure is the general case: at a retail gas station the thresholds are 75,000 gallons of gasoline and 100,000 gallons of diesel fuel (all grades combined), and they apply only to fuel in tanks entirely underground that met every applicable underground storage tank requirement at all times during the preceding calendar year (40 CFR 370.10(a)(2)(ii) and (iii)); otherwise the general threshold applies. The report covers the previous calendar year and is due March 1 (40 CFR 370.45). Below every threshold, a request still has to be answered: when your LEPC, SERC or fire department asks for Tier II information, the threshold is zero and the information is due within 30 days (40 CFR 370.10(b), 370.45(b)). Where Rhode Island's rules above are stricter, they apply on top.

The full federal picture, Tier I versus Tier II, counting and penalties, is on the EPCRA Tier II hub. The list that feeds it is the chemical inventory.

HazComFast keeps each jobsite's chemical quantities next to its safety data sheets and exports the Tier II data as an Excel workbook, a CSV file and a PDF summary.

Who gets the Tier II report in Rhode Island?

Copies also go to the local fire department and, by email by March 1, to the chairperson of the facility's LEPC district, listed on the DEM page. The federal rule is that the report reaches the LEPC, the SERC and the fire department with jurisdiction (42 U.S.C. 11022(a)(1)); in a state that takes the report in one system and passes it on, that system can meet the rule, and the state's own steps above say which applies.

Keep the chemical list behind your Tier II report current

Tier II is an EPCRA filing to your state and local agencies, not an OSHA citation. The same chemical inventory feeds your SDS binder and the report, so keep it in one place.
