(A) Each owner or operator of a facility who is required to prepare or have available a material safety data sheet for a hazardous chemical under the "Occupational Safety and Health Act of 1970," 84 Stat. 1590, 29 U.S.C. 651, as amended, and regulations adopted under it, or who is required to submit a list under division (A), (D), or (E), or is authorized to submit material safety data sheets instead of that list under division (E), of section 3750.07 of the Revised Code and who had present at the facility during the preceding calendar year an amount of a hazardous chemical exceeding the applicable threshold quantity established by rules adopted under division (B)(1)(b) or (C)(5) of section 3750.02 of the Revised Code, shall annually by the first day of March submit to the local emergency planning committee of the emergency planning district in which the facility is located, the emergency response commission, and the fire department having jurisdiction over the facility an emergency and hazardous chemical inventory form containing tier I information as prescribed in divisions (A)(1) to (4) of this section. The owner or operator may instead submit an inventory form containing tier II information as prescribed in divisions (B)(1) to (7) of this section for any hazardous chemical present at the facility. If the commission, committee, or fire department having jurisdiction over a facility has requested under division (B) of this section that the owner or operator of a facility submit an inventory form containing tier II information as prescribed in that division, the owner or operator shall by the first day of March of each year subsequent to that request submit to the commission, committee, and fire department an inventory form containing tier II information as prescribed in divisions (B)(1) to (7) of this section instead of an inventory form containing the tier I information prescribed in this division, until such time as the commission authorizes the owner or operator to resume the annual submission of an inventory form containing tier I information. An owner or operator who has been so required to annually submit an inventory form containing tier II information may, at any time, request the commission to authorize the owner or operator to resume annual submission of an inventory form containing tier I information.

The emergency and hazardous chemical inventory form shall include as tier I information all of the following information with respect to each hazardous chemical that was present at the facility during the preceding calendar year in an amount exceeding the applicable threshold quantity:

(1) An estimate of the maximum amount in pounds of the hazardous chemicals in each category established in rules adopted under division (B)(1)(b) or (C)(5) of section 3750.02 of the Revised Code that were present at the facility at any time during the preceding calendar year. The estimate for each such category shall be provided in the appropriate reporting range established by those rules.

(2) An estimate of the average daily amount in pounds of the hazardous chemicals in each such category that were present at the facility during the preceding calendar year. The estimate for each such category shall be provided in the appropriate reporting range established by those rules.

(3) The general location at the facility of hazardous chemicals in each category;

(4) Any other information required by rules adopted under division (B)(1)(e) of section 3750.02 of the Revised Code.

(B) Upon the request of the commission or the committee or fire department having jurisdiction over the facility, the owner or operator of a facility that is subject to this section shall submit an emergency and hazardous chemical inventory form containing tier II information as prescribed in divisions (B)(1) to (7) of this section within thirty days after receiving the request.

An emergency and hazardous chemical inventory form shall include as tier II information the following additional information for each hazardous chemical that was present at the facility during the preceding calendar year in an amount exceeding the applicable threshold quantity:

(1) The chemical name or common name of the hazardous chemical as provided on the material safety data sheet and its chemical abstract service number;

(2) An estimate of the maximum amount in pounds of the hazardous chemical that was present at the facility at any time during the preceding calendar year. The estimate shall be provided in the appropriate reporting range established by rules adopted under division (B)(1)(b) of section 3750.02 of the Revised Code.

(3) An estimate in pounds of the average daily amount of the hazardous chemical that was present at the facility during the preceding calendar year. The estimate shall be provided in the appropriate reporting range established by those rules.

(4) A brief description of the manner of storage of the hazardous chemical;

(5) The location at the facility of the hazardous chemical;

(6) An indication as to whether the owner or operator chooses to withhold information about the hazardous chemical from disclosure as a trade secret and, if so, whether he has filed a claim with the administrator of the United States environmental protection agency for protection of that information as a trade secret pursuant to rules adopted under division (B)(2)(d) of section 3750.02 of the Revised Code or with the commission pursuant to rules adopted under division (B)(5) of that section, as appropriate;

(7) Any other information required by rules adopted under division (B)(1)(e) of section 3750.02 of the Revised Code.

If the commission has not prescribed emergency and hazardous chemical inventory forms, the owner or operator shall submit the information required by divisions (A)(1) to (4) or (B)(1) to (7) of this section to the commission by letter.

(C) No owner or operator of a facility where a hazardous chemical is produced, used, or stored in an amount that exceeds the threshold quantity for the chemical established in rules adopted under division (B)(1)(b) or (C)(5) of section 3750.02 of the Revised Code shall fail to submit:

(1) An emergency and hazardous chemical inventory form containing tier I information as required by division (A) of this section;

(2) An emergency and hazardous chemical inventory form containing tier II information in compliance with division (B) of this section when requested to do so under that division or when required to do so under division (A) of this section.
