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

How to file

Kentucky facilities file Tier II, with revisions, updates and payments, through Hazconnect.

“Kentucky facilities are required to submit their Tier II Reports using the Hazconnect® online reporting system.” source

“Annual Tier II Reports, revisions, updates and payments are all submitted through Hazconnect®.” source

Deadline

Reports and fees are due by March 1 each year.

“Tier II reports and fees are due annually by March 1.” source

Fees

A report filed after March 1 carries a one-time late fee of $250 per facility.

“Reports submitted after the due date of March 1, will be fined a one-time late fee of $250 per facility.” source

State thresholds

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

“Facilities are required to report their possession of Extremely Hazardous Substances (EHS) when they are stored at 500 pounds or the Threshold Planning Quantity, whichever is less.” source

“Facilities must also report any hazardous chemical which requires a Safety Data Sheet, per the OSHA Hazard Communication Standard, and which is stored in the amount of 10,000 pounds or more.” source

Who gets the report

One Hazconnect filing reaches the KERC, the LEPC and the fire department; no separate copies are needed.

“Facilities no longer need to submit to the Kentucky Emergency Response Commission, Local Emergency Planning Committee and Fire Departments. A single submission through Hazconnect® takes care of all three.” source

State-specific rule

A facility at or above the threshold planning quantity of an extremely hazardous substance also completes an EHS plan, reviewed by the LEPC under the KERC's guidance.

“Facilities that meet or exceed the Threshold Planning Quantity for hazardous substances must complete an EHS plan.” source

“EHS plans are led and reviewed by Local Emergency Planning Committees (LEPCs) under the guidance of the Kentucky Emergency Response Commission (KERC).” 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 Kentucky'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.
