Title
143rd Street and LaGrange Road Intersection Improvements - Underground Orphan Storage Tank Removal
History
During the course of work undertaken for the watermain relocation project associated with the 143rd Street and LaGrange Road Intersection Improvement project, certain contaminated soils were encountered which required special handling and disposal. In addition to special soils, an undocumented liquid underground storage tank (Orphan Tank) was discovered which requires removal and disposal.
The Orphan Tank discovered at the southeast corner of 143rd Street and LaGrange Road appears to be approximately 700 gallons in size and is partially filled with water. The location of the Orphan Tank is in conflict with future structures at this location. The most efficient means of accommodating the planned construction required of the upcoming improvements is the advance removal of the tank.
This location is also the site of reported petroleum leaking underground storage tank (LUST) releases from former Citgo and 7-Eleven Service Station operations. Known contamination is present at the location of the Orphan Tank, presumably the result of the reported LUST incidents. Therefore, it is likely that the Office of State Fire Marshall (OSFM) will require that a release report be filed with the Illinois Emergency Management Agency (IEMA) when the UST is removed.
During the course of previous advance work requiring environmental oversight, management and special soils disposal, environmental assessment and oversight services were requested and provided by V3 Engineers and Consultants and special soils disposal services were requested and provided by RAMSCO, INC. Staff finds the work and associated fees for previously performed work by both firms reasonable and their service professional and timely.
In an effort to expedite this work and contain the professional and construction costs associated with this unanticipated work, Staff requested quotes from both V3 and RAMSCO, Inc. for services and work required to permit, document, remove, clean and dispose of this Orphan Tank. Staff has reviewed both proposals and finds them reasonable and customary for services and work required to perform similar removal and remediation tasks elsewhere.
It is Staff’s recommendation that the proposal received from V3 for the permitting and coordination, removal observation and closure reporting required for successful removal of this Orphan Tank be accepted in an amount not to exceed $4,000.
It is also Staff’s recommendation with the concurrence of the consultant (V3) that the proposal provided by RAMSCO, Inc. for the work associated with the Orphan Tank removal, cleaning and disposal be accepted in an amount not to exceed $5,855.
Both V3 and RAMSCO, Inc. are currently on-site performing similar services elsewhere for the improvement project and both have acquired institutional knowledge unique to this project which best positions them to provide an economical solution for this current need.
The Village continues to seek full reimbursement for this work, as well as the contaminated soils identified during the course of this project from every current or former operator or landowner that may be contributory to the discovered contamination.
On October 4, 2010, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.

Financial Impact
Funds for this unanticipated tank removal project are available within the approved Fiscal Year 2010 Budget within the Village’s Capital Improvement Fund. This added cost will not adversely impact the overall project budget and the additional costs associated with this Orphan Tank removal project keeps the total costs associated with this scope of work below the approved budget value.
Recommended Action/Motion
I move to approve authorizing a Contract with V3 Engineers and Consultants in an amount not to exceed $4,000 for Professional Environmental Engineering services required to prepare and permit, oversee and document the closure and removal of a previously undocumented Leaking Underground Storage Tank (Orphan Tank) detected during the course of routine work associated with the 143rd Street and LaGrange Road Intersection Improvement Project;
And
Approve authorizing a Contract with RAMSCO, Inc. in an amount not to exceed $5,855 for construction work required to excavate, clean, transport and dispose of the subject Orphan Tank.
And
Approve authorizing the Village Manager to execute contracts with V3 and RAMSCO, Inc. for the associated Professional Services and Construction activity.
