Illinois Administrative Code › Title 41 - FIRE PROTECTION › Part 176 - ADMINISTRATIVE REQUIREMENTS FOR UNDERGROUND STORAGE TANKS AND THE STORAGE, TRANSPORTATION, SALE AND USE OF PETROLEUM AND OTHER REGULATED SUBSTANCES › Subpart C - RELEASE REPORTING AND SITE ASSESSMENT › Section 176.330 - Procedures for Site Assessments

Current through Register Vol. 48, No. 28, July 12, 2024
a)
				All site assessments and related reports must be conducted or prepared under
				the supervision of a Licensed Professional Engineer or Licensed Professional
				Geologist. All site assessment work shall meet accepted engineering standards
				or accepted standards for the practice of professional geology and be conducted
				according to the best professional judgment and diligence of the supervising
				Licensed Professional Engineer or Licensed Professional Geologist, as the case
				may be.
b) Owners or operators
				shall measure for the presence of a release where contamination is most likely
				to be present at the UST site by conducting sampling in the same manner and
				following the same procedures as required under the Illinois Pollution Control
				Board's Petroleum Underground Storage Tanks rules at 35 Ill. Adm. Code
				734.210(h)(1) and
				(2). Samples must be analyzed for the same
				applicable indicator contaminants as required under 35 Ill. Adm. Code
				734.405. All sampling must meet
				the same data quality and certification requirements as set forth in 35 Ill.
				Adm. Code 734.415 and
				734.420. If soil borings are
				involved the owner or operator must follow the same requirements as set forth
				in 35 Ill. Adm. Code 734.425 and
				734.435. For all UST removals,
				samples shall be taken in native soil with the excavation for the removal still
				open and prior to backfill and with the STSS still on site. For
				abandonment-in-place, samples may be taken prior to or on the day of
				abandonment-in-place and shall meet the requirements of this Section. In
				selecting sample types, sample locations and sample measurement methods, owners
				or operators shall also consider the nature of the stored substance, the type
				of initial alarm or cause for suspicion, if any, the method of tank removal or
				abandonment-in-place, the types of backfill, the depth of groundwater and other
				factors appropriate for identifying the presence and source of a release.
				Packaging for shipping or delivery should be done in a manner that will
				preserve the sample and prevent deterioration or dilution, as for example,
				putting samples in sealed containers in ice.
c) Within 45 days after receipt of lab
				results from a full site assessment pursuant to subsection (b), owners or
				operators must designate and electronically submit to OSFM, on OSFM electronic
				forms (titled "Site Assessment Results" form and available at
https://sfm.illinois.gov/about/divisions/petroleum-chemical-safety/applications-and-forms.html
),
				a "contamination" or "no contamination" result indicating whether a release has
				occurred, along with associated lab results. This determination shall be based
				upon an evaluation of lab results to determine whether any contamination has
				been found. The determination must be certified by a Licensed Professional
				Engineer or Licensed Professional Geologist. Even if "no contamination" is
				being reported, the analytical report with tables and a site map showing
				sampling/boring locations shall be submitted to OSFM. In the event a suspected
				release was previously called into IEMA and is being confirmed by site
				assessment, the "contamination" or "no contamination" result on the Site
				Assessment Results form shall be provided to IEPA in addition to
				OSFM.
d) In the event that sampling
				or other site observations disclose evidence of a release or site assessment
				lab results show site contamination, the owner or operator shall immediately
				notify IEMA and any other required entities of a suspected release, as required
				by Section 176.320, and begin corrective
				action pursuant to 35 Ill. Adm. Code 734.
e) Records generated from site assessments
				and related activity shall be kept at the site (or available within 30 minutes
				or before OSFM completes its inspection, whichever is later) and may not be
				discarded or destroyed unless and until a No Further Remediation (NFR) letter
				is issued by IEPA or until the site permanently ceases the activity involved in
				using the USTs and any site assessments required under this Part are completed
				and show no evidence of contamination. Owners or operators claiming that
				required records were destroyed, discarded or lost prior to September 1, 2010
				or by a prior owner of the subject UST property shall conduct a new site
				assessment when the assessment is required by OSFM rules for continued or
				future use of the USTs.
