standards.
(1) COCs that are required to be
evaluated are dependent on the
petroleum fraction of the released product. The
volunteer shall evaluate additional
petroleum constituents or typical
impurities to ensure
applicable standards are met
.
The volunteer shall assess
by assessing
and
evaluate
evaluating the risk indicator compounds for each
appropriate
petroleum fraction
including the
following
as follows:
(a) For light petroleum fractions, such as
natural gasoline, gasohol, or naphtha solvents, the
volunteer shall analyze
environmental
media for benzene, toluene, ethylbenzene, methyl tert-butyl ether,
total xylenes, naphthalene, and 1,2,4-trimethylbenzene.
(b) For middle petroleum fractions, such as
kerosene, diesel fuel, or jet fuel, the volunteer
shall analyze
environmental media
for benzene, toluene, ethylbenzene, total xylenes, acenaphthene, anthracene,
chrysene, benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene,
benzo[k]fluoranthene, dibenzo[a,h]anthracene, fluoranthene, fluorene,
indeno[1,2,3-cd]pyrene, naphthalene, and pyrene.
(c) For heavy petroleum fractions, such as
hydraulic oil, lube oil, or residual fuel oils, the
volunteer shall analyze
environmental
media for acenaphthene, anthracene, chrysene, benzo[a]pyrene,
benzo[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene,
dibenzo[a,h]anthracene, fluoranthene, fluorene, indeno[1,2,3-cd]pyrene,
naphthalene, and pyrene. Where the heavy petroleum is used motor oil, used
cutting oil, or hydraulic oil, the volunteer shall identify additional COCs
that may be typical impurities of the used heavy petroleum fractions product,
and the volunteers shall include such COCs in the analysis, as
appropriate.
(d) For releases of
automotive gasoline formulated before January 1, 1996, racing fuel, or aviation
gasoline, the volunteer shall analyze
environmental media for the constituents
listed in paragraph (C)(1)(a) of this rule as well as 1,2-dichloroethane and
1,2-dibromoethane (ethylene dibromide).
(e) For petroleum from an unknown source,
the volunteers shall analyze
environmental media for benzene,
ethylbenzene, toluene, total xylenes, methyl tert-butyl ether, acenaphthene,
anthracene, chrysene, benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene,
benzo[k]fluoranthene, dibenzo[a,h]anthracene, fluoranthene, fluorene,
indeno[1,2,3-cd]pyrene, naphthalene, and pyrene. The volunteer shall identify
additional COCs that may be typical impurities of used petroleum fractions, and
the volunteer shall include such additional
COCs in the analysis, as appropriate.
(2) Evaluation of compliance with
applicable
standards. The concentrations of
COCs evaluated in accordance with paragraph
(D)(3)(a)
(D)(3)(a)(i) of this rule on or from the
property
shall meet
applicable standards for the media and
exposure pathways evaluated.
As appropriate, the
volunteer shall evaluate
applicable standards for
petroleum
and
petroleum's constituents or impurities in the following manner:
(a)
The volunteer
shall conduct a
A human health
property-specific risk assessment
that includes derivation of applicable
standards
is to be conducted using
property-specific standards derived in accordance with paragraph (D) of
this rule
, or
shall use generic numerical standards provided in
rule
3745-300-08 of the
Administrative Code. The
volunteer may use generic numerical standards for the
exposure pathways included in rule
3745-300-08 of the
Administrative Code.
The volunteer shall evaluate
other
Other exposure pathways
are to be evaluated in accordance with paragraph
(D) of this rule.
The volunteer shall conduct an
evaluation of cumulative
Cumulative risks
are to be evaluated in accordance with paragraphs
(B) and (D)(3)(d) of this rule.
(b)
The volunteer shall determine soil
Soil saturation concentrations of total
petroleum
hydrocarbons
are to be determined utilizing the
vertical hydraulic conductivity of the unsaturated soil or otherwise
demonstrate the soil type most representative of the soils impacted by
petroleum. The corresponding
petroleum fraction shall meet the residual
saturation concentration in table I of this rule.
