Ohio EPA's State Emergency Response Commission accepts Tier II filings by email, and the process itself is simple -- but there's a real filing fee involved that a lot of facilities don't see coming, because emailing a file doesn't feel like the kind of thing that comes with an invoice.
Ohio EPA's Right-to-Know Program runs Tier II reporting for the state SERC. Build your report in Tier2 Submit, export it as a .t2s file, and email it to SERC@epa.ohio.gov along with a signed certification letter -- that letter is a specific, documented requirement, not an optional nicety.
Standard federal thresholds -- 10,000 pounds for hazardous chemicals, 500 pounds or the TPQ for extremely hazardous substances.40 CFR 370.10 Deadline is March 1st for the previous calendar year.
Every January, Ohio EPA mails regulated facilities a cover letter and a pre-printed SERC filing fee worksheet with an assigned Receivable ID number. If you never received one -- maybe you're a new facility, or it got lost in the mail -- email SERC@epa.ohio.gov with "INVOICE NEEDED" in the subject line and they'll generate one. Payment goes through Ohio EPA's eBusiness Center portal, or by check mailed to their Cleveland P.O. box.
Beyond the SERC email, a site map has to be included -- it can be uploaded within Tier2 Submit itself under the attachment tab -- and a paper copy generated from the software goes to your local fire department along with that map. Keep last year's .t2sfile rather than deleting it once you're done; Ohio's own instructions specifically note that next year's software can import the prior year's file to save you re-entering everything from scratch.
HazRecord keeps your chemical inventory current year over year, so the import-from-last- year step Ohio recommends is already built into how the platform carries data forward, and it generates the certification-letter-ready export alongside your .t2s file.

HazRecord helps facilities organize chemical inventory, SDS records, storage locations, and Tier II reporting preparation in one place.
