- Keystone Color Works, Inc. (Keystone or Facility) is enrolled in the One Cleanup Program. The One Cleanup Program is EPA's vision for how different cleanup programs at all levels of government can work together to meet that goal, and ensure that resources, activities, and results are effectively coordinated and communicated to the public. It is a long term initiative designed to support the ongoing planning and quality improvement efforts of EPA cleanup programs.
- Remediation of the Facility is being addressed in accordance with Pennsylvania's Land Recycling and Environmental Remediation Standards Act (Act 2). Keystone is part of the Northwest Triangle (NWT) Act 2 remediation which covers a multi-block area of separate properties covering 14.5 acres in the northwestern corner of the City of York. A Final Report for the NWT properties was submitted to the Pennsylvania Department of Environmental Protection (PADEP) for final review and approval on December 28, 2011.
- The NWT area is generally bounded to the north and west by the Codorus Creek, and is bisected by various rail lines operated by York Rail. Various commercial and industrial activities occurred at many of these properties since the early 1900s, and historic fill materials were apparently placed at a thickness of up to four feet across some of the properties to increase and level their grades. The City of York Redevelopment Authority (RDA) is remediating rehabilitating, and/or redeveloping these impacted and underutilized properties as part of the city's revitalization activities. Based on a number of preliminary environmental investigations, conditions of potential environmental concern were identified at six (6) of the properties: York Rail, Keystone Color Works, B&C Fasteners, Weaver's Auto Body, Trestle Area, and Ohio Blenders.
- EPA sets national goals to measure progress toward meeting the nation's major environmental goals. For Corrective Action, EPA evaluates two key environmental indicators for each facility: (1) current human exposures under control and (2) migration of contaminated groundwater under control. Once EPA completes its review of available information, an environmental indicator determination will be prepared and posted to this website.
- The Keystone Color Works site is located at 151 West Gay Street and is comprised of two (2) adjoining parcels totaling 0.725 acres. The building and/or former building components cover much of the property. The eastern third of the property consists of a concrete pad that had been the floor for a section of the former building that was demolished in the 1990s. The remainder of the property consists of narrow grassy strips of land located to the north and west of the building.
- The earliest known use of the property was in the manufacture of farm machinery from 1887 to 1908. Keystone has produced organic and inorganic pulp pigments for the wallpaper and surface coating trades at the facility since 1919. Hazardous substances, in the form of raw materials, finished product, and waste materials, have historically been stored throughout the building. Until the 1980s, pigment production consisted of mixing raw materials in 300 and 3,000-gallon wooden tanks, collecting the resultant pigment solid, pressing it in filter presses to remove the water, and packaging the finished product.
- Many of the properties within the NWT, including Keystone, have been the subject of various environmental investigations for the purpose of characterizing these properties to identify and delineate potential contamination. These investigations supported the development and implementation of environmental remediation plans as part of the site redevelopment activities.
- Soil sampling results for the soils located along the western edge of the Keystone building showed concentrations of lead exceeding the PADEP Residential Direct Contact Medium Specific Concentration (MSC) and Soil-to-Groundwater MSC. Lead was also detected at a concentration at or above the PADEP Non-Residential Direct Contact MSC at two sampling locations.
- Soil was excavated from along the western side of the Keystone building to a depth of up to approximately two feet in the areas where PADEP MSC exceedances were detected. Approximately 156 tons of contaminated soils were removed from the Keystone property. Following soil excavation, post-excavation confirmatory soil sampling for lead was conducted, and all post-excavation samples showed concentrations of lead to be below PADEP Residential MSCs.
- Because samples demonstrated concentrations of lead in excess of the Soil-to-Groundwater MSC, one shallow groundwater monitoring well (MW-1S) was installed near the center of the northwestern property boundary. This well provided for the assessment of groundwater quality at this location, and also supported the site-wide assessment of groundwater quality. Groundwater sample results for MW-1S showed that lead was not detected at concentrations greater than the Residential Used Aquifer MSC.
- All soils identified with constituent concentrations above the PADEP Residential Statewide Health MSCs have been removed from the site. Based upon the removal of these soils, there are no current or future exposure pathways or associated risks of potential concern.
- With respect to groundwater, groundwater is currently not used at the site, and future groundwater use is not anticipated based on the site's location within the City of York and the availability of public water supplies. As a result, exposure to groundwater is not a potential concern.
- June 1, 2004 - A preliminary Phase I Environmental Assessment Report that addressed all of the NWT properties of concern was completed by Edge Environmental, Inc
- June 2, 2005 – A Revised Phase I Environmental Site Assessment of the properties of concern was completed by Pennoni Associates, Inc.
- December 21, 2005 – GTS Technologies, Inc. completed an Interim Site Characterization Report for Keystone.
- December 28, 2011 – Act 2 Final Report for NWT Properties prepared by ARC Group, Inc.

- Plans for beneficial use of the NWT properties are under development, but are expected to consist of a mixture of residential, commercial, and potentially light industrial.
