Each point is followed by the words of the state's own page.
How to file
Paper filing remains possible with the SERC compliance manual and forms, downloadable or sent on request.
“If you elect not to submit your information electronically, or do not receive information in the mail, you may download the SERC compliance manual and forms from the website.” source
How to file
A Tier2 Submit file (.t2s) goes on a flash drive or by email to both SERC@epa.ohio.gov and the LEPC; the local fire department gets a paper copy printed from Tier2 Submit with a site map.
“Facilities opting to file using Tier 2 Submit may submit their report as a .t2s file on a flash drive or by email to both SERC@epa.ohio.gov and the LEPC.” source
“A paper copy generated from the Tier 2 Submit software and a site map should also be sent to the local jurisdictional fire department.” source
Fees
Ohio charges a SERC filing fee: early each January the Right-to-Know Program mails each regulated facility a fee worksheet with an assigned receivable ID, and the fees can be paid online.
“In the first few weeks of January, Ohio EPA's Right-to-Know Program sends each regulated facility a cover letter and pre-printed SERC filing fee worksheet with an assigned Receivable ID number.” source

State-specific rule
Oil and gas extraction sites have their own instruction booklet, inventory forms and filing fee worksheet.

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 Ohio'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.
