Louisville District releases the Proposed Plan for Hanna City Air Force Station for public review
The U.S. Army Corps of Engineers invites you to review and comment on the Proposed Plan for remedial action at the former Hanna City Air Force Station, a Formerly Used Defense Site in Hanna City, Illinois.
The site was used by the U.S. Air Force from 1952 to 1968 as a radar tracking and investigation facility. The U.S. Army Corps of Engineers has recently completed a study of the former Hanna City Air Force Station concerning potential military munitions and alternatives for further action.
Surface soil exceeding values based on the Illinois Tiered Approach to Corrective Action Objectives (TACO) Tier 1 industrial/commercial remediation goals will be removed. These remediation goals will be protective of receptors under current land use, and will also be protective of residential users should the property be converted to residential use in the future. The preferred alternative is presented in the proposed plan. Copies of the Proposed Plan are available for public review in the Farmington Area Public District Library, 266 East Fort Street, Farmington, Illinois, (309)-245-2175.
The U.S. Army Corps of Engineers encourages you to comment on the Proposed Plan during the 30-day Public Comment Period, May 3 through June 1, 2013. Written comments may be submitted by mail, using the official comment form, postmarked no later than June 1, 2013 to the following address: U.S. Army Corps of Engineers, Louisville District, Attn: Dr. David Brancato, 600 Dr. Martin Luther King, Jr. Place, Louisville, Kentucky, 40202. Public comments received during this period will be considered in the final decision-making process for the former Hanna City Air Force Base.
A public meeting will be held at the Hanna City Park District Gymnasium located at 511 Main Street, Hanna City, Illinois. The public meeting will be held on May 20, 2013 from 6:00 to 8:00 p.m. (CST) for the public to ask questions and submit comments and concerns in person regarding the recommended cleanup plan.

History
Over the past 20 years, the U.S. Army Corps of Engineers (USACE) has been conducting environmental investigations at the former Hanna City Air Force Station. The site was used by the U.S. Air Force from 1952 to 1968 as a radar tracking and investigation facility. Since the deactivation of the Hanna City Air Force Station in 1968, areas of the property have been owned, occupied, or used by several groups: the Illinois Department of Corrections (IDoC) as a Work Camp, Peoria County as a SWAT training site, the Federal Aviation Administration as a navigation facility, and the Village of Hanna City as a water treatment facility. The site is located on Farmington Road 10 miles west of the City of Peoria and 2 miles west of the Village of Hanna City in Peoria County, Illinois. The property is currently owned by Peoria County and the Village of Hanna City.
Environmental Investigations
• A 1992 Preliminary Assessment was conducted by USACE, Chicago District which included a site visit and interviews with former and current site personnel.
• Five underground storage tanks were used and removed by IDoC from 1997-2002.
• A Site Inspection in 1996 conducted for USACE, Buffalo District investigated several areas of potential concern. Most of these areas required further sampling in the 2006 Supplemental Site Inspection. Pesticides, polychlorinated biphenyls and volatile organic hydrocarbons were ruled out as chemicals of potential concern. Polycyclic aromatic hydrocarbons (PAHs) in surface and subsurface soils and metals in soil and groundwater were considered chemicals of potential concern. A surface radiation survey indicated that site radiation levels were within background levels.
• A Remedial Investigation in 2008 conducted for USACE, Louisville District investigated several areas of potential concern from the previous study. Five areas were identified as posing potential risks to onsite workers and onsite residents due to regular exposure to PAHs in soils. The groundwater is not a concern at the site since metals in groundwater are naturally occurring from the soil.
• A Feasibility Study has been prepared which compares three cleanup alternatives for the site to remediate the risk from PAHs in soils. This Feasibility Study will be finalized in 2012 and will be followed by a Proposed Plan which will recommend a cleanup plan.
• This Proposed Plan was submitted to the public for review during the 30-day Public Comment Period, beginning on May 3, 2013 and ending on June 1, 2013. A public meeting will be held at the Hanna City Park District Gymnasium located at 511 Main Street, Hanna City, Illinois. The public meeting will be held on May 20, 2013 from 6:00 to 8:00 p.m. (CST) for the public to ask questions and submit comments and concerns in person regarding the recommended cleanup plan.
