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 Idaho'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.

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.
