Environmental

Citizens Energy Group has been working closely with the Indiana Department of Environmental Management to develop environmental remediation plans for the Indianapolis Coke Plant site, which produced coke and manufactured gas from 1908-2007.

Contamination at the coke plant site is being carefully monitored. Citizens has placed more than 100 monitoring wells and collected hundreds of soil, sediment, groundwater and surface water samples and conducted thousands of laboratory analyses throughout the 80-acre coke plant site. Contamination at the site is largely the result of the coke manufacturing processes that took place at the site before environmental practices and regulations were developed.

Environmental studies indicate that coal tar constituents are the primary contaminants of concern at the site. Coal tar, which was a byproduct of the coke manufacturing process, has a variety of commercial and industrial uses including as an asphalt sealant and ingredient in shampoo and soap.

Frequently Asked Questions - Environmental

Q. When will environmental cleanup be complete?
A. We expect remediation work will take more than 10 years, which is the typical timeframe for remediating such a large, complex site with thorough regulatory oversight.

Q. Are there any hazardous materials being removed from the site?
A. Solid and hazardous wastes regulated by IDEM will be removed from the site in accordance with all local, state and federal regulations.

Q. There is a lot of asthma in the neighborhoods around the plant. Is the plant site contributing to poor air quality?
A. We do not believe the plant site is contributing to air quality problems in the neighborhood.

Q. How do we intend to get rid of bad soil? Will the neighbors have a say in whether we remove or cap bad soil areas?
A. The remediation strategies are still being developed. The strategies will be protective of human health and the environment, and may involve removal of impacted soils. The VRP program has a public process for commenting on the Remediation Work Plans. Citizens will have public meetings and outreach to help the community to understand the plans.

Q. The neighbors want Citizens to test soils at their homes, not just on the plant site. They believe the plant fouled their soil and they worry about the safety of their vegetable gardens.
A. Citizens recommends that neighbors contact the Marion County Health Department for information on soil testing.

Q. Will we check for histoplasmosis in the air when we demolish buildings?
A. Citizens has inspected all of our buildings prior to demolition for asbestos and other hazardous materials including bird droppings (the source of spores that cause histoplasmosis). During these inspections, Citizens found no evidence of bird droppings that would cause a release of spores that cause histoplasmosis. Should we discover evidence of such bird droppings, they will be properly removed and disposed of prior to demolition.

Q. Do you have any plans to clean up the coal dust residue from our neighborhoods?
A. Citizens is working with the Indiana Department of Environmental Management on a comprehensive environmental remediation plan for the Prospect site. We don't anticipate this plan will include cleaning up coal dust outside of the plant site.

Q. Will Citizens do any job training for remediation work at the main plant site?
A. Citizens will not be creating a job training program for remediation work at the plant site. However, the company is certainly open to others creating such programs to support remediation work throughout Marion County.
