EPA and IDEM Approve City's Long Term Control Plan

In a collaborative effort, the Indiana Department of Environmental Management (IDEM) and the United States Environmental Protection Agency (EPA) have reviewed and approved the City’s Long Term Control Plan (LTCP).  The LTCP is the name for the mandate originating in the Clean Water Act of 1972, which requires the elimination of releasing contaminated water into the nation’s waterways.  The plan is a negotiated settlement between the City and the regulatory agencies. 

 

The City's recommended LTCP is a combination of several controls that will be constructed over a 20 year period at a cost of approximately $120 million. The LTCP, once implemented, is expected to result in the capture and treatment of 96% of the combined sewer overflow (CSO) volume that currently comes from the City’s system.

 

Some of the proposed LTCP projects include the construction of wastewater treatment plant improvements to increase the plant’s sustained peak flow capacity; rehabilitation of a portion of the existing lagoons at the former International Paper site for CSO storage; the elimination of six CSO outflow locations; and construction of a new main lift station. 

 

Additionally, construction of various green infrastructure projects, in an area north of Cherry St. and west of 9th St., will be completed in an attempt to reach the target level of control within the set 20 year schedule.  The City may begin implementing the LTCP immediately according to the EPA and IDEM.
