Facilities in Ohio storing hazardous chemicals above EPA reporting thresholds file an annual Tier II report through Ohio EPA SERC. Email .t2s file (with a signed certification letter attached) to SERC@epa.ohio.gov and the LEPC; a paper copy plus site map goes to the local fire department.
Organize chemical inventory, SDS records, and threshold tracking, then generate a ready-to-submit .t2s file.
Before submitting, we recommend independently validating the file using EPA’s own Tier2 Submit software to confirm it opens and validates as expected: good practice for any compliance filing, regardless of which tool prepared it.
