Site Description

The Peters Cartridge Factory Site is a partially abandoned manufacturing facility located at 1415 Grandin Road, Kings Mills, Ohio. The site consists of two distinct areas. The first area, Area A, occupies approximately 15 acres located in the floodplain and along the south valley wall of the Little Miami River. The topography varies from approximately 620 to 730 feet above sea level. The site is bordered to the north by the Little Miami Scenic River Bikeway and the Little Miami River, to the east by Grandin Road, to the south by agricultural land at the top of the valley wall, and to the west by undeveloped bottom land along the river. The ground surface is predominantly covered by asphalt and/or concrete. The remaining unpaved portion is characterized by steep terrain and mature deciduous vegetation. The second area, Area B, is a 56-acre parcel of unimproved wooded land on the southern, west/southwestern and east/southeastern borders of the 15-acre parcel.

The site buildings were constructed in 1916 as a munitions manufacturing facility known as the Peters Cartridge Company. The main site buildings are situated on the level ground next to the Little Miami River. The remnants of concrete bunkers and other buildings are scattered along the steep slope of the valley wall along the southern part of the site. Three swales convey water down the steeply sloping valley wall into stom sewers that run beneath the main buildings. The storm sewers are largely filled with debris. The site is currently occupied by several small businesses. The main buildings are in poor condition with most of the windows broken and roofs leaking.

The U.S. Environmental Protection Agency (EPA) proposed the site to the National Priorities List (NPL) in April 2003 and finalized the site on the NPL in September 2012.

Site Responsibility

The Remington Arms Company purchased the Peters Cartridge Company in 1934 and continued munitions manufacturing operations at the site until 1944 when the site was sold. The Remington Arms Company was acquired by E. I. duPont de Nemours and Company (DuPont Company). The DuPont Company, by reason of its ownership of Remington Arms, is jointly and severally liable for all investigation and cleanup activites at the site.

The site is being addressed through federal, state and potentially responsible parties actions.

Threats and Contaminants

An environmental assessment of Area A was conducted in 1987 during which on-site soils were sampled at depths of one, four, eight and twelve feet. Lead, copper and mercury-contaminated soils were found near each building in Area A, consistent with the manufacture of munitions.

The Ohio Environmental Protection Agency (Ohio EPA) conducted an Expanded Site Inspection in 1999 during which soil, sediment, groundwater, and fish tissue samples were collected from Area A. Volatile, semi-volatile, and pesticide organic compounds were detected in the soil samples, and lead was detected in the on-site groundwater monitoring wells. A release of copper into the Little Miami River was observed, and lead was detected in the sediment samples.

Cleanup Progress

The DuPont Company signed an Administrative Order on Consent with EPA in July 2004 under which the company agreed to conduct a Remedial Investigation/Feasibilty Study (RI/FS) at the site. EPA approved the final RI Report in February 2009 and the final FS Report in June 2009.

Additionally, Ohio EPA conducted a Water Quality Study in 2007 along the section of the Little Miami River that is adjacent to the Peters Cartridge Site, in part to determine whether there is any ecological impact on the Little Miami River from site contaminants. The study results, published in November 2007, indicate that the Peters Cartridge Site is not causing impairment to the Little Miami River.

EPA issued a Proposed Plan for site cleanup in June 2009 and held a public meeting in mid-July 2009 to present the Proposed Plan to the public. Additionally, EPA developed a Community Involvement Plan for the site in 2009.

EPA signed a Record of Decision on September 28, 2009, which detailed the remedy for the site. The selected remedy includes excavation and on-site consolidation of contaminated soil and limited action for groundwater with use-restriction institutional controls. EPA believes these response actions will be protective of human health and the environment. 

EPA began negotiating with DuPont in 2010 for the remedial design and remedial action (RD/RA), but a settlement was not reached. EPA issued a unilateral administrative order (UAO) on March 30 2012, requiring DuPont to conduct the RD/RA work. DuPont began the remedial design process in April 2012 and submitted the 30% Design in 2013. DuPont submitted the Final Design in November 2014 and EPA approved it in December 2014, along with the Remedial Action Work Plan. 

Remedial action cleanup work at the site began in the spring of 2015. The majority of the work, including excavating the contaminated soil and backfilling, building the on-site containment unit and placing the contaminated soil in the unit, is scheduled to be completed by late fall of 2015. Site restoration activities, including revegetation of the site, will likely be conducted in early 2016.

EPA intends to issue an Explanation of Significant Differences (ESD) in summer 2015 to document some significant (but not fundamental) changes to the remedy that were found to be necessary during the remedial design. EPA held a public availability session in February 2015 to discuss with the community the changes to the selected remedy and the schedule for the cleanup work.
