(2) Reserved. On or after January 1, 2001 for gasoline and/or diesel fuel located at a retail gas station when one or more of the following conditions are met: Amounts of gasoline equal to or exceeding seventy-five thousand gallons (all grades combined); Amounts of diesel fuel equal to or exceeding one hundred thousand gallons (all combined grades); In tank (s) that were not entirely underground; Or located at a retail gas station that was not in compliance at all times during the preceding calendar year with all applicable underground storage tank (UST) requirements (OAC 1301:7-9) State UST program approved by U.S. EPA. For the purposes of this rule, retail gas station means a retail facility engaged in selling gasoline and/or diesel fuel principally to the public, for motor vehicle use on land.

(1) On or before March 1, 1988, (or March first of the first year after the facility first becomes subject to this rule covering all hazardous chemicals present at the facility during the preceding calendar year in amounts equal to or greater than ten thousand pounds, or that are extremely hazardous substances present at the facility in an amount greater than or equal to five hundred pounds (or fifty-five gallons) or the threshold planning quantity, whichever is less.

(2) On or before March 1, 1989, (or March first of the second year after the facility first becomes subject to this rule), covering all hazardous chemicals present at the facility during the preceding calendar year in amounts equal to or greater than ten thousand pounds, or that are extremely hazardous substance present at the facility in an amount greater than or equal to five hundred pounds (or fifty-five gallons) or the threshold planning quantity, whichever is less.

(3) Reserved. On or after January 1, 2001, covering gasoline and/or diesel fuel located at a retail gas station when one or more of the following conditions are met: Amounts of gasoline equal to or exceeding seventy-five thousand gallons (all combined grades); Amounts of diesel fuel equal to or exceeding one hundred thousand gallons (all grades combined); In tank (s) that were not entirely underground; Or located at a retail gas station that was not in compliance at all times during the preceding calendar year with all applicable underground storage tank (UST requirements (OAC 1301:7-9/State UST program approved by U.S. EPA. For purposes of this rule, retail gas station means a retail facility engaged in selling gasoline and/or diesel fuel principally to the public, for motor vehicle use on land.

(C) The minimum threshold for reporting in response to a facility specific, chemical specific request for the submission of an MSDS as prescribed in paragraph (E) of rule 3750-30-15 of the Administrative Code or an inventory form containing Tier II information as prescribed in paragraph (H) of rule 3750-30-20 of the Administrative Code shall be zero. Where the commission or committee is responding to a request subject to section 3750.10 of the Revised Code, all requirements of that section shall be met.

(1) Determining the quantities and providing the required information on each component in the mixture which is a hazardous chemical, or

(2) Determining the quantities and providing the required information on the mixture itself, so long as the reporting of mixtures by a facility under rule 3750-30-15 of the Administrative Code is in the same manner as under rule 3750-30-20 of the Administrative Code where practicable.

(E) The calculation of the threshold quantities present in a mixture shall be performed as follows:

(1) If the reporting is on each component of the mixture which is a hazardous chemical, then the concentration of the hazardous chemical, in weight per cent (greater than one per cent or .1 per cent if carcinogenic) shall be multiplied by the mass (in pounds) of the mixture to determine the quantity of the hazardous chemical in the mixture.

(2) If the reporting is on the mixture itself, the total quantity of the mixture shall be reported.
