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. No such facility specific, chemical specific request under this section shall be used to calculate fees assessable under rule 3750-50-01 of the Administrative Code or to expand the content or scope of the map described in paragraphs (F)(4) and (H)(7) of rule 3750-30-20 of the Administrative Code.

(D) The owner or operator of a facility may calculate the amount of a hazardous chemical present at a facility and meet the hazardous chemical reporting requirements of rule 3750-30-20 (inventory reporting) of the Administrative Code and rule 3750-30-15 (list or SDS reporting) of the Administrative Code for a hazardous chemical that is a mixture by either of the following:

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

(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 0.1 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, the total quantity of the mixture shall be reported.

(3) If extremely hazardous substances are hazardous components of a mixture, the quantity of the extremely hazardous substance in each mixture shall be aggregated to determine if the threshold value has been reached for the facility. Reporting may be accomplished by reporting on the component or the mixture even if the amount of the mixture is below the reporting threshold. Aggregation of non-extremely hazardous substances present in mixtures and in pure form is not required, but may be done if a facility is reporting all hazardous chemicals in mixtures by component.
