35 Ill. Adm. Code 734.210
Early Action
Section 734.210 Early Action
a) Upon
confirmation of a release of petroleum from a UST system in accordance with
regulations promulgated by the OSFM, the owner or operator, or both, must
perform the following initial response actions:
1) Immediately
report the release to IEMA (e.g., by telephone or electronic mail);
BOARD NOTE: The OSFM rules for
the reporting of UST releases are found at 41 Ill. Adm. Code 176.320(a).
2) Take
immediate action to prevent any further release of the regulated substance to
the environment; and
3) Immediately
identify and mitigate fire, explosion and vapor hazards.
b) Within
20 days after initial notification to IEMA of a release plus 14 days, the owner
or operator must perform the following initial abatement measures:
1) Remove
as much of the petroleum from the UST system as is necessary to prevent further
release into the environment;
2) Visually
inspect any aboveground releases or exposed below ground releases and prevent
further migration of the released substance into surrounding soils and
groundwater;
3) Continue
to monitor and mitigate any additional fire and safety hazards posed by vapors
or free product that have migrated from the UST excavation zone and entered
into subsurface structures (such as sewers or basements);
4) Remedy
hazards posed by contaminated soils that are excavated or exposed as a result
of release confirmation, site investigation, abatement or corrective action
activities. If these remedies include treatment or disposal of soils, the
owner or operator must comply with 35 Ill. Adm. Code 722, 724, 725, and 807
through 815;
5) Measure
for the presence of a release where contamination is most likely to be present
at the UST site, unless the presence and source of the release have been
confirmed in accordance with regulations promulgated by the OSFM. In selecting
sample types, sample locations, and measurement methods, the owner or operator
must consider the nature of the stored substance, the type of backfill, depth
to groundwater and other factors as appropriate for identifying the presence
and source of the release; and
6) Investigate
to determine the possible presence of free product, and begin removal of free
product as soon as practicable and in accordance with Section 734.215 of this
Part.
c) Within
20 days after initial notification to IEMA of a release plus 14 days, the owner
or operator must submit a report to the Agency summarizing the initial
abatement steps taken under subsection (b) of this Section and any resulting
information or data.
d) Within
45 days after initial notification to IEMA of a release plus 14 days, the owner
or operator must assemble information about the site and the nature of the
release, including information gained while confirming the release or
completing the initial abatement measures in subsections (a) and (b) of this
Section. This information must include, but is not limited to, the following:
1) Data on the nature and
estimated quantity of release;
2) Data
from available sources or site investigations concerning the following factors:
surrounding populations, water quality, use and approximate locations of wells
potentially affected by the release, subsurface soil conditions, locations of
subsurface sewers, climatological conditions and land use;
3) Results of the site
check required at subsection (b)(5) of this Section; and
4) Results
of the free product investigations required at subsection (b)(6) of this
Section, to be used by owners or operators to determine whether free product
must be recovered under Section 734.215 of this Part.
e) Within
45 days after initial notification to IEMA of a release plus 14 days, the owner
or operator must submit to the Agency the information collected in compliance
with subsection (d) of this Section in a manner that demonstrates its
applicability and technical adequacy.
f)
Notwithstanding
any other corrective action taken, an owner or operator may, at a minimum, and
prior to submission of any plans to the Agency, remove the tank system, or
abandon the underground storage tank in place, in accordance with the
regulations promulgated by the Office of the State Fire Marshal
(see 41
Ill. Adm. Code 160, 170, 180, 200).
The owner may remove visibly
contaminated fill material and any groundwater in the excavation which exhibits
a sheen
.
For purposes of payment of early action costs, however, fill
material shall not be removed
in an amount in excess of 4 feet from the
outside dimensions of the tank.
[415 ILCS 5/57.6(b)] Early action may also
include disposal in accordance with applicable regulations or ex-situ treatment
of contaminated fill material removed from within 4 feet from the outside
dimensions of the tank.
g) For
purposes of payment from the Fund, the activities set forth in subsection (f)
of this Section must be performed within 45 days after initial notification to
IEMA of a release plus 14 days, unless special circumstances, approved by the
Agency in writing, warrant continuing such activities beyond 45 days plus 14
days. The owner or operator must notify the Agency in writing of such
circumstances within 45 days after initial notification to IEMA of a release
plus 14 days. Costs incurred beyond 45 days plus 14 days must be eligible if
the Agency determines that they are consistent with early action.
BOARD NOTE: Owners or operators
seeking payment from the Fund are to first notify IEMA of a suspected release
and then confirm the release within 14 days to IEMA pursuant to regulations
promulgated by the OSFM. See 41 Ill. Adm. Code 170.560 and 170.580. The Board
is setting the beginning of the payment period at subsection (g) to correspond
to the notification and confirmation to IEMA.
h) The
owner or operator must determine whether the areas or locations of soil
contamination exposed as a result of early action excavation (e.g., excavation
boundaries, piping runs) or surrounding USTs that remain in place meet the most
stringent Tier 1 remediation objectives of 35 Ill. Adm. Code 742 for the
applicable indicator contaminants.
1) At a
minimum, for each UST that is removed, the owner or operator must collect and
analyze soil samples as indicated in subsections (h)(1)(A) through (E). The
Agency must allow an alternate location for, or excuse the collection of, one
or more samples if sample collection in the following locations is made
impracticable by site-specific circumstances.
A) One
sample must be collected from each UST excavation wall. The samples must be
collected from locations representative of soil that is the most contaminated
as a result of the release. If an area of contamination cannot be identified
on a wall, the sample must be collected from the center of the wall length at a
point located one-third of the distance from the excavation floor to the ground
surface. For walls that exceed 20 feet in length, one sample must be collected
for each 20 feet of wall length, or fraction thereof, and the samples must be
evenly spaced along the length of the wall.
B) Two
samples must be collected from the excavation floor below each UST with a
volume of 1,000 gallons or more. One sample must be collected from the
excavation floor below each UST with a volume of less than 1,000 gallons. The
samples must be collected from locations representative of soil that is the
most contaminated as a result of the release. If areas of contamination cannot
be identified, the samples must be collected from below each end of the UST if
its volume is 1,000 gallons or more, and from below the center of the UST if
its volume is less than 1,000 gallons.
C) One
sample must be collected from the floor of each 20 feet of UST piping run
excavation, or fraction thereof. The samples must be collected from a location
representative of soil that is the most contaminated as a result of the
release. If an area of contamination cannot be identified within a length of
piping run excavation being sampled, the sample must be collected from the
center of the length being sampled. For UST piping abandoned in place, the
samples must be collected in accordance with subsection (h)(2)(B) of this
Section.
D) If
backfill is returned to the excavation, one representative sample of the
backfill must be collected for each 100 cubic yards of backfill returned to the
excavation.
E) The
samples must be analyzed for the applicable indicator contaminants. In the
case of a used oil UST, the sample that appears to be the most contaminated as
a result of a release from the used oil UST must be analyzed in accordance with
Section 734.405(g) of this Part to determine the indicator contaminants for
used oil. The remaining samples collected pursuant to subsections (h)(1)(A)
and (B) of this Section must then be analyzed for the applicable used oil
indicator contaminants.
2) At a
minimum, for each UST that remains in place, the owner or operator must collect
and analyze soil samples as follows. The Agency must allow an alternate location
for, or excuse the drilling of, one or more borings if drilling in the
following locations is made impracticable by site-specific circumstances.
A) One
boring must be drilled at the center point along each side of each UST, or
along each side of each cluster of multiple USTs, remaining in place. If a
side exceeds 20 feet in length, one boring must be drilled for each 20 feet of
side length, or fraction thereof, and the borings must be evenly spaced along
the side. The borings must be drilled in the native soil surrounding the USTs
and as close practicable to, but not more than five feet from, the backfill
material surrounding the USTs. Each boring must be drilled to a depth of 30
feet below grade, or until groundwater or bedrock is encountered, whichever is
less. Borings may be drilled below the groundwater table if site specific
conditions warrant, but no more than 30 feet below grade.
B) Two
borings, one on each side of the piping, must be drilled for every 20 feet of
UST piping, or fraction thereof, that remains in place. The borings must be
drilled as close as practicable to, but not more than five feet from, the
locations of suspected piping releases. If no release is suspected within a
length of UST piping being sampled, the borings must be drilled in the center
of the length being sampled. Each boring must be drilled to a depth of 15 feet
below grade, or until groundwater or bedrock is encountered, whichever is
less. Borings may be drilled below the groundwater table if site specific conditions
warrant, but no more than 15 feet below grade. For UST piping that is removed,
samples must be collected from the floor of the piping run in accordance with
subsection (h)(1)(C) of this Section.
C) If
auger refusal occurs during the drilling of a boring required under subsection
(h)(2)(A) or (B) of this Section, the boring must be drilled in an alternate
location that will allow the boring to be drilled to the required depth. The
alternate location must not be more than five feet from the boring's original
location. If auger refusal occurs during drilling of the boring in the
alternate location, drilling of the boring must cease and the soil samples
collected from the location in which the boring was drilled to the greatest
depth must be analyzed for the applicable indicator contaminants.
D) One
soil sample must be collected from each five-foot interval of each boring
required under subsections (h)(2)(A) through (C) of this Section. Each sample
must be collected from the location within the five-foot interval that is the
most contaminated as a result of the release. If an area of contamination
cannot be identified within a five-foot interval, the sample must be collected
from the center of the five-foot interval, provided, however, that soil samples
must not be collected from soil below the groundwater table. All samples must
be analyzed for the applicable indicator contaminants.
3) If
the most stringent Tier 1 remediation objectives of 35 Ill. Adm. Code 742 for
the applicable indicator contaminants have been met, and if none of the
criteria set forth in subsections (h)(4)(A) through (C) of this Section are
met, within 30 days after the completion of early action activities the owner
or operator must submit a report demonstrating compliance with those
remediation objectives. The report must include, but not be limited to, the
following:
A) A
characterization of the site that demonstrates compliance with the most
stringent Tier 1 remediation objectives of 35 Ill. Adm. Code 742 for the
applicable indicator contaminants;
B) Supporting
documentation, including, but not limited to, the following:
i) A
site map meeting the requirements of Section 734.440 of this Part that shows
the locations of all samples collected pursuant to this subsection (h);
ii) Analytical
results, chain of custody forms, and laboratory certifications for all samples
collected pursuant to this subsection (h); and
iii) A
table comparing the analytical results of all samples collected pursuant to
this subsection (h) to the most stringent Tier 1 remediation objectives of 35
Ill. Adm. Code 742 for the applicable indicator contaminants; and
C) A site
map containing only the information required under Section 734.440 of this
Part.
4) If
the most stringent Tier 1 remediation objectives of 35 Ill. Adm. Code 742 for
the applicable indicator contaminants have not been met, or if one or more of
the following criteria are met, the owner or operator must continue in
accordance with Subpart C of this Part:
A) There
is evidence that groundwater wells have been impacted by the release above the
most stringent Tier 1 remediation objectives of 35 Ill. Adm. Code 742 for the
applicable indicator contaminants (e.g., as found during release confirmation
or previous corrective action measures);
B) Free
product that may impact groundwater is found to need recovery in compliance
with Section 734.215 of this Part; or
C) There
is evidence that contaminated soils may be or may have been in contact with
groundwater, unless:
i) The owner
or operator pumps the excavation or tank cavity dry, properly disposes of all
contaminated water, and demonstrates to the Agency that no recharge is evident
during the 24 hours following pumping; and
ii) The
Agency determines that further groundwater investigation is not necessary.
