Rule 3750-20-10 | Calculation of quantities for comparison with threshold planning quantities for solids and mixtures.
[Comment: For dates of non-regulatory government
publications, publications of recognized organizations and associations,
federal rules, and federal statutory provisions referenced in this rule, see
paragraph (YY) of this rule titled "Referenced materials."] (A) If a container or storage vessel
holds a mixture or solution of an extremely hazardous substance, then the
concentration of extremely hazardous substance, in weight per cent (greater
than one per cent), shall be multiplied by the mass (in pounds) in the vessel
to determine the actual quantity of extremely hazardous substance
therein. (B) Extremely hazardous substances that
are solids are subject to either of two threshold planning quantities as shown
in or referenced by rule 3750-20-30 of the Administrative Code (e.g., five
hundred/ten thousand pounds). The lower (five hundred pounds) threshold
planning quantity applies only if the solid: (1) Exists in powdered
form and has a particles size less than one hundred microns. (2) Is handled in
solution or in molten form. (3) Meets the criteria
for a national fire protection association (NFPA) rating of two, three or four
for reactivity. If the solid does not meet any of these criteria,
the solid is subject to the upper (ten thousand pound) threshold planning
quantity as shown in or referenced by rule 3750-20-30 of the Administrative
Code. (C) For the three forms of solids that
are listed in paragraphs (B)(1) to (B)(3) of this rule, the quantity of
extremely hazardous substance present is determined as follows: (1) The threshold planning quanity for a
solid that exist in a powdered form with a particulate size less than one
hundred micron level may be determined by multiplying the weight per cent of
solid with a particle size less than one hundred microns in a particular
container by the quantity of solid in the container. (2) The threshold planning quantity for a
solid in solution may be determined by multiplying the weight per cent of
non-reactive solid in the solution in a particular container by the total
weight of solution in the container and then multiply by 0.2. This reduction in
quantity may not be used to determine the amount present at one-time at a
facility for reporting compliance with hazardous chemical reporting
requirements under federal 40 C.F.R. Part 370 and Chapter 3750-30 of the
Administrative Code, "Hazardous Chemical Reporting." (3) The threshold planning quantity for a
solid solid in molten form may be determined by multiplying the weight of the
non-reactive solid in molten form by 0.3. (D) For purposes of this rule, "mixture" means a
heterogeneous association of substances where the various individual substances
retain their identities and can usually be separated by mechanical means.
Includes solutions or compounds but does not include alloys or
amalgams. (E) For purposes of this rule,
"non-reactive solid" means any substance listed in appendix A or B of
40 CFR Part 355- "Emergency Planning and Notification" with two
threshold planning quantity values, the higher TPQ being ten thousand
pounds. (F) For purposes of this
rule,"reactive solid" means any extremely hazardous substance denoted
with "a" in the "notes" column in appendix A or B of 40 CFR
Part 355-"Emergency Planning and Notification." (G) For purposes of this
rule,"solution" means any aqueous or organic, slurries, viscous
solutions, suspensions, emulsions, or pastes.

Rule 3750-20-76 | Types of exercises.
(A) The following types of exercises shall be employed by each committee and the commission subject to the annual exercise requirement of their chemical emergency response and preparedness plans under divisions (A)(12) and (C) of section 3750.04 of the Revised Code and division (B)(13) of section 3750.02 of the Revised Code for the commission. (1) A "tabletop exercise" is an activity in which commission, committee, planning district, local emergency management personnel, elected or appointed officials, and other individuals with emergency responsibilities are gathered together to discuss planned response to various simulated emergency situations. Using existing plans, the exercise is designed to elicit constructive discussion by the participants as they examine and attempt to resolve response problems. The purpose is for participants to evaluate plans and to resolve questions of coordination and assignment of responsibilities throughout the exercise. Each tabletop exercise shall demonstrate at least three but no more than five of the objectives defined in paragraph (D) of rule 3750-20-70 of the Administrative Code. (2) A "functional exercise" is an activity designed to test or evaluate the operational capability of an individual function, or complex activities within a function of emergency response. This type of exercise is applicable where the response activity is capable of being evaluated in isolation from other emergency management activities. A functional exercise fully tests specific functions of the committee's chemical emergency response and preparedness plan. An EOC or command post is activated and used to demonstrate the use of command structure. Each functional exercise shall physically demonstrate at least four but no more than seven of the objectives defined in paragraph (D) of rule 3750-20-70 of the Administrative Code. (3) A "full-scale exercise" is an activity intended to evaluate the operational capability of the overall emergency management systems in an interactive manner. A full-scale exercise involves the testing of a majority of the functions of the committee's chemical emergency response and preparedness plan. A full-scale exercise requires actual field play that includes mobilization and actual deployment of emergency personnel and resources required to demonstrate coordination and response capabilities. An EOC or command post shall be activated to coordinate operational field capabilities. Each full-scale exercise shall physically demonstrate eight or more of the objectives as defined in paragraph (D) of rule 3750-20-70 of the Administrative Code. (B) The response to an actual hazardous materials incident may qualify as an exercise. In order to qualify, the committee must submit, within thirty days of the completion of the response to the incident, a completed "LEPC Exercise Notice Form" identifying the exercise objectives which were demonstrated by the actual response. Upon receipt of the "LEPC Exercise Notice Form," the Ohio emergency management agency will contact the committee to schedule a meeting to conduct an interview of all principal participants to determine whether or not the identified exercise objectives were successfully tested.
