| Proposed Corrective Action Activities |
During the Summer of 2005, construction is proposed on a cap for the landfill. The first step is to re-shape the landfill surface to improve slopes for proper drainage. Next, a high-density polyethylene (HDPE) geomembrane liner will be placed above the waste to prevent rainwater from entering the landfill. Above the liner, either a man-made geocomposite drainage layer or a sand drainage layer will be installed to speed the runoff of rainwater from the landfill. Above the drainage layer will be 18 to 24 inches of topsoil that will allow for the establishment of native prairie plants as vegetative cover. Landfill gas will be collected within the trash layer through corrugated pipes, and then vented through aboveground pipes to the atmosphere. The majority of the leachate seeps come from rainwater entering the present cover. Because the improved cap will cause rainwater to flow off the landfill rather than into the landfill, the production of leachate from the landfill should greatly decrease. Construction Activities Are Intended To Meet The Following Goals:
This work is proposed to begin in May 2005 and take approximately four months. |
| Project Funding | The State has pursued enforcement activities against the past owner and operator in an effort to require them to perform all t he necessary closure and maintenance activities. State funding, enforcement monies, and financial assurance dedicated to the landfill by the operator will be used for corrective action activities. Bishop Landfill is one of thirty-three abandoned landfills identified as needing state funding to assure protection of public health and the environment. This list of thirty-three was developed by the Illinois EPA based on field investigations. These landfills have ceased accepting waste but were never properly closed |
| Future Operations | Illinois EPA proposes to conduct two years of maintenance
including: monitoring the cap and vegetation for erosion and making
necessary repairs. It is important that the plant roots become firmly
established to avoid erosion problems, which could expose refuse or
damage the liner.
Illinois EPA recommends no public uses of the landfill. Activities such as four-wheeling, motorcycle riding and hiking could damage the cap and liner. Damage by human activity would allow more water to enter the landfill and produce leachate, which could then enter the creek. In addition, potentially unsafe gases will continue to emit from vents for some time posing a risk to those in close proximity. |

An Information Repository for the Bishop Landfill is located at the Litchfield Carnegie Public Library, 400 North State Street, Litchfield, Illinois 62056 (217-324-3866). The Information Repository contains technical documents for the site investigation and proposed construction activities. A Public Comment Period regarding the Bishop Landfill Designs is scheduled for September 28, 2004 through October 27, 2004.

The
Illinois EPA plans to improve the current deteriorating state of
this landfill by regrading and capping the top of the landfill. Efforts
will be taken to control future erosion and establish a healthy vegetative
cover on the landfill.
