[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
:
exists in powdered form and has a particles size
less than one hundred microns; or is handled in solution or in molten form; or
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, it 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.
(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:
(C)(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.
(D)(2) The
threshold planning quantity for a
amount of 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
quantity
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."
.
(E)(3) The
threshold planning quantity for a solid
amount of solid in molten form
must
may be
multiplied
determined by
multiplying the
weight of the nonreactive solid in molten form by0.3
to determine whether the lower threshold planning quantity
is met.
(F)(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.
