Update: ESI managers sentenced for criminal violations

A vice-president and two managers of ESI were sentenced  for felony violations of the Clean Water Act on April 4, 2011. They were convicted of intentionally discharging untreated wastewater and stormwater from the facility directly into the Indianapolis sewer system. More information >>


ESI began operation in December 1999 as a commercial used oil processing facility. The facility collected, processed, recovered, and disposed of nonhazardous wastewater from industrial and commercial manufacturing plants. All materials received into the facility were treated and processed to separate the contaminants. The water collected during this process was discharged separately into the city of Indianapolis sanitary sewer system. The contaminants were further processed into a form that allowed for proper recycling or disposal. Any oils recovered in the process were shipped off-site to be reused. The site was designed so that the stormwater at the site was captured in its internal sewer system and ultimately run through its wastewater processing equipment prior to being discharged into the city sanitary sewer system.

On March 15, 2007, during a heavy rainfall, untreated oil and water from the site flowed into the city sewer system through a by-pass sewer that had been left open. This release resulted in contamination of surrounding commercial and residential properties. The resulting cleanup lead to the by-pass sewer being permanently sealed. In 2007, ESI was notified by a customer that a shipment of used oil from the site had contained PCBs. As a result, the equipment was decontaminated. Another release occurred in 2009 resulting again in contamination of area commercial and residential properties. Another cleanup took place, but these two releases indicate the need for runoff from the site to be controlled.

In October 2010 ESI filed bankruptcy leaving behind tanks containing hazardous chemicals such as sulfuric acid and polychlorinated biphenyls, or PCBs.  EPA began a cleanup to address potential imminent health threats posed by these abandoned chemicals. One of the primary concerns was the potential for chemicals from the site to be released into the city sanitary sewer system or area surrounding the site in the event of a heavy rain or snow melt. For this reason, a primary focus of the work was and continues to be managing stormwater runoff.

Site Updates

November 2013

Cleanup of the ESI Environmental Inc site was recently completed by a group of companies considered potentially responsible for the contamination. The companies were doing the cleanup in response to a legal agreement they signed in 2011. On October 9, 2012, the United States Environmental Protection Agency issued a notice of completion letter to the companies stating that all of the requirements listed in the agreement had been met.

The notice of completion in no way releases the Respondents from any potential future obligations to perform additional work to address the same or other conditions at the Site.  Similarly this notice of completion does not release Respondents from any recordkeeping, payment, penalties for any violation of the ASAOC, or other obligations that extend beyond the date of this notice.
