SUPPLEMENTAL AGREEMENT
TIERED APPROACH TO CORRECTION OBJECTIVES AGREEMENT
This Agreement is entered into this 27thday oFobi y2019 pursuant to 35 Ill.
Adm. Code 742.1020 by and between R& K Petroleum, Inc., an Illinois corporation, referred to
herein as "Owner/Operator", and the City of Elgin ("City"). The Owner/Operator and City are
referred to as"Parties."
1. This Agreement is not binding upon the City until it is signed by the undersigned
representative of the City and before signing, this Agreement constitutes an offer by
Owner/Operator. The duly authorized representative of Owner/Operator has signed this
Agreement, and this Agreement is binding upon it, its successors and assigns, upon execution by
the City.
2. Owner/Operator Stipulates:
a. Owner/Operator is pursuing Corrective Action for the property located at 1725
Larkin Avenue, Elgin, Illinois ("the Site"). The Illinois Emergency Management Agency has
assigned Incident Numbers 871107 and 922846 to this matter. The property located at 1725
Larkin Avenue, Elgin, Illinois and Numbers 871107 and 922846 is sometimes collectively
referred to as "the Site" or "Incident Numbers 871107 and 922846." As part of the
Owner/Operator's Corrective Action, the Owner/Operator and the City have entered into a
Highway Authority Agreement (the "HAA") for the roads Larkin Avenue and Lyle Avenue
("Rights-of-Way") located along the property frontage, which HAA (including its exhibits) is
attached hereto as Exhibit 1 and made a part hereof. The City has agreed to prohibit the use of
groundwater as a potable water supply within the area of the corporate limits of Elgin described
and depicted in the HAA. For purposes of this agreement, "Corrective Action" is defined as
active remediation, passive remediation, investigation and monitoring of "Contaminants of
Concern" which are defined as those contaminants released from the Site which have possibly
impacted soil/and or groundwater within the Rights-of-Way or within the area covered by the
HAA in excess of applicable Tier 1 objectives as described in the HAA, or any combination of
these activities defined herein.
b. Attached as Exhibits A and B to the HAA are; (i) site maps prepared by
Owner/Operator which show the area of estimated contaminated soil and/or groundwater at the
time of this Agreement in the Rights-of-Way above Tier 1 residential levels under 35 Ill. Adm.
Code 742; and (ii)tables prepared by Owner/Operator showing concentrations of Contaminants
of Concern, hereafter "Contaminants," in soil and/or groundwater within the area described in
Exhibit A and which shows the applicable Tier 1 soil remediation objectives for property and
Tier 1 objectives for groundwater of the Illinois Pollution Control Board ("IPCB") that are
exceeded. The Rights-of-Way, and only the Rights-of-Way, as described in Exhibit C of the
HAA, adjacent to the Site and adjoining property is subject to this Agreement. As the drawings
in the Exhibits are not surveyed plats, the boundary of the Rights-of-Way in the Exhibits may be
an approximation of the actual Rights-of-Way lines. Contaminants have been delineated into the
Rights-of-Way, the Owner/Operator has represented that the area of the Rights-of-Way is
adequate to encompass soil and groundwater in the Rights-of-Way possibly impacted with
Contaminants from a release at the Site.
c. The Illinois Emergency Management Agency has assigned Incident Numbers
871107 and 922846 to this matter.
d. Owner/Operator intends to request risk-based, site specific soil and/or
groundwater remediation objectives from the Illinois Environmental Protection Agency
("IEPA")under 35 I11. Adm. Code 742.
e. Under these rules, use of risk-based, site specific remediation objectives in the
Rights-of-Way may require the use of a highway authority agreement as defined in 35 Ill. Adm.
Code 742.1020, in substantially the form of the HAA.
3. The City stipulates that:
The City holds a fee simple interest or a dedication for highway purposes in the Rights-
of-Way, or the Rights-of-Way are platted streets, and has jurisdiction of the Rights-of-Way. As
such, the City exercises access control over the use of the groundwater beneath the Rights-of-
Way and over access to the soil beneath the Rights-of-Way.
4. The Parties stipulate that:
a. Contemporaneously with the execution of this Agreement, R& K Petroleum, Inc.
and the City have executed the HAA attached hereto as Exhibit 1, and will submit the executed
HAA to the IEPA. Under 35 Ill. Adm. Code 742.1020, this Agreement is intended to establish
undertakings by the Owner/Operator to the City in consideration of the City entering into the
HAA and the City's agreements herein that it will not allow the use of groundwater under the
Rights-of-Way as a potable or other domestic supply of water, and that it will limit access as
described herein to soil under the Rights-of-Way that is contaminated from the release at levels
above residential Tier 1 remediation objectives.
b. The IEPA and/or Attorney General ("AG") must review and approve the HAA,
and the HAA shall be referenced in IEPA's "No Further Remediation" determination in the
chain of title for the Site in the county where the Site is located.
c. This Agreement shall be null and void should the IEPA or AG not approve the
HAA, or should the HAA not be referenced in the "No Further Remediation" determination,
provided, however, that this Agreement shall be effective between the Owner/Operator and the
City immediately upon signature by their representatives.
5. The City promises IEPA and the Owner/Operator that it will prohibit the use of
groundwater that is contaminated from the release at the Site at levels above Tier 1 residential
remediation objectives beneath its Rights-of-Way within the area covered by the HAA as a
potable or other domestic supply of water and that it otherwise will limit access to soil as
described herein under the Rights-of-Way that is impacted from the release at levels above Tier 1
residential remediation objectives. As the pavement in the Rights-of-Way may be considered an
engineered barrier, the Owner/Operator agrees to reimburse the City for such maintenance
2
activities requested by Owner/Operator or the IEPA in writing as are reasonably necessary to
maintain such pavement area(s) as a barrier. The City does not otherwise agree to perform
maintenance of the Rights-of-Way, nor does it agree that the Rights-of-Way will always remain
a highway or that it will maintain the Rights-of-Way as an engineered barrier.
6. The Owner/Operator agrees to indemnify and hold harmless the City and other highway
authorities, if any, maintaining the Rights-of-Way by an agreement with the City and the City's
agents, contractors, officials, officers and employees for all lawsuits, claims, losses, injuries,
damages,judgments, or other obligations asserted against or costs incurred by them, including
reasonable attorney's fees and court costs(collectively, "Obligations"), associated with the
release of Contaminants of Concern regardless whether said obligations or costs were caused by
the negligence of them.
7. As an additional consideration, and subject to the requirements of paragraph 12,
Owner/Operator agrees to reimburse the City for those reasonably necessary costs it has incurred
or will incur in responding appropriately to the suspected presence of Contaminants of Concern
in the Rights-of-Way as a result of the release of contaminants at this Site, including but not
limited to, identifying, investigating, handling, storing and disposing of contaminated soil and
groundwater in the Rights-of-Way as a result of the release of Contaminants at this Site by
Owner/Operator. Owner/Operator further agrees to reimburse the City for those reasonably
necessary costs it has incurred in the amount of $1,500.00 in reviewing and negotiating this
Agreement. A check made payable to "The City of Elgin" shall be tendered to the City by the
Owner/Operator in the amount of$1,500.00 concurrently with the execution of this Agreement.
8. This Agreement shall be binding upon all successors in interest to the Owner/Operator or
Rights-of-Way. A successor in interest of the City would include a highway authority to which
the City would transfer jurisdiction of the highway.
9. Violation of the terms of this Agreement by Owner/Operator, or by the City, may be
grounds for voidance of this Agreement. Violation of the terms of the HAA by the City will not
void this Agreement, unless the IEPA has determined that the violation is grounds for voiding
the HAA and the City has not cured the violation within such time as IEPA has granted to cure
the violation.
10. This Agreement shall continue in effect from the date of this Agreement until a) the
Rights-of-Way are demonstrated to be suitable for unrestricted use, b) there is no longer a need
for the HAA, and c) the IEPA has, upon written request to the IEPA by the Owner/Operator and
notice to the City, amended the notice in the chain of title for the site to reflect unencumbered
future use of that Rights-of-Way.
11. This Agreement constitutes full settlement of claims the City may have arising from the
possible release of Contaminants of Concern associated with Incident Numbers 871107 and
922846, and is not in settlement of claims of the IEPA or any other State Agency.
12. This Agreement does not limit the City's ability to construct, reconstruct, improve,
repair, maintain and operate a highway upon its property or to allow others to use the Rights-of-
3
Way by permit.To that extent,the City reserves the right,and the right of those using or working
in its Rights-of-Way under permit, to remove contaminated soil or groundwater above Tier 1
residential objectives from its Rights-of-Way and to dispose of them as they deem appropriate, in
accordance with applicable environmental regulations, so as to avoid causing a further release of
the Contaminants and to protect human health and the environment.
Prior to taking any such action, the City may, if practicable as determined by the City,
first give Owner/Operator written notice that it intends to perform a site investigation in the
Rights-of-Way and remove or dispose of contaminated soil or groundwater to the extent
necessary for its work. Failure to give notice shall not constitute a violation of this Agreement.
The removal or disposal shall be based upon the site investigation (which may be modified by
field conditions during excavation), which Owner/Operator may review or may perform, if
requested to do so by the City. If practicable, as determined by the City, the City may request
Owner/Operator to remove and dispose of the contaminated soil and/or groundwater necessary
for the City's work in advance of that work. The Owner/Operator shall reimburse the reasonable
costs incurred by the City to perform the site investigation and to dispose of any contaminated
soil or groundwater regardless of whether notice has been given to Owner/Operator. There is a
rebuttable presumption that the Contaminants found in the highway Rights-of-Way arose from
the release of Contaminants from the Site. Should Owner/Operator not reimburse the reasonable
costs under the conditions set forth herein, this Agreement shall be null and void, at the City's
option, upon written notice to Owner/Operator by the City that those costs have not been
reimbursed. Owner/Operator may cure that problem within twenty (20) working days by
making payment. Failure to give notice to the Owner/Operator or failure to give the
Owner/Operator the opportunity to remove and dispose of contaminated soil and/or groundwater
is not a violation of this Agreement and shall not be a defense to a claim for reimbursement or
the work should not have been done. Should Owner/Operator not reimburse the costs identified
herein, this Agreement shall be null and void in addition to such other remedies as may be
available to the City by law.
Notwithstanding any termination of this Agreement, the City shall have the right to
enforce the reimbursement obligations of Owner/Operator, and the City shall be entitled to
recover all of its reasonable costs (including attorneys' fees) in connection with such
enforcement.
13. Written Notice required by this Agreement must be mailed to the following:

14. The City's sole responsibility under this Agreement with respect to others using the
Rights-of-Way under permit from the City is to include the following, or similar language, in the
future standard permit provisions and to make an effort to notify its current permit holders of the
following:
As a condition of this permit, the permittee shall request the City's Public
Works Department to identify sites in the Right-of-Way where access to
contaminated soil or groundwater is governed by Tiered Approach to
Corrective-Action Objectives ("TACO") Agreements. The permittee shall take
measures before, during and after any access to these sites to protect worker
safety and human health and the environment. Excavated, contaminated soil
should be managed off-site in accordance with all environmental laws.
Owner/Operator hereby releases the City from liability for breach of this Agreement or
the HAA by others under permit and indemnifies the City against claims that may arise from
others under permit causing a breach of this Agreement or the HAA. Owner/Operator agrees
that its personnel, if any at the Site who are aware of the HAA, will notify anyone they know
is excavating in the Rights-of-Way about the HAA.
15. Should the City breach this Agreement or the HAA, Owner/Operator's sole remedy is for
an action for damages in the Circuit Court for the 16th Judicial Circuit, Kane County, Illinois.
Any and all claims for damages against the City, its agents, contractors, employees or its
successors in interest arising at any time for a breach of this Agreement or the HAA are limited
to an aggregate maximum of One Thousand Five Hundred Dollars ($1,500). No other breach by
the City, its agents, contractors, employees and its successors in interest of a provision of this
Agreement or the HAA is actionable in either law or equity by Owner/Operator against the City
or them, and Owner/Operator hereby releases the City, its agents, contractors, employees and its
successors in interest for any cause of action it may have against them, other than as allowed in
this paragraph, arising under this Agreement or environmental laws, regulations or common law
governing the impacted soil or groundwater in the Rights-of-Way or in the area covered by the
HAA. Should the City convey, vacate or transfer jurisdiction of that Rights-of-Way,
Owner/Operator may pursue an action under this Agreement against the successors in interest,
other than a State Agency, in court.
16. This Agreement is entered into by the City in recognition of laws passed by the General
Assembly and regulations adopted by the IPCB which encourage a tiered-approach to
remediating environmental contamination. This Agreement is entered into by the City in the
spirit of those laws and under its right and obligations as property owner. Should any provisions
of this Agreement be struck down as beyond the authority of the City, however, this Agreement
5
shall be null and void, except that all costs and expenses to be paid by Owner/Operator as
provided in this Supplemental Agreement which have been incurred by the City prior to
termination shall be reimbursed by Owner/Operator within 45 days after the Supplemental
Agreement becomes null and void, and Owner/Operator's obligations under Paragraph 6 of this
Supplemental Agreement shall survive any termination of this Supplemental Agreement.
IN WITNESS WHEREOF, the City has caused this Agreement to be signed by its
Mayor.
