The 40-acre Westline site is located in Westline, Pennsylvania. A lumber processing plant operated at the site during the early 1900s. A chemical facility on site converted lumber into charcoal, methanol and acetic acid until 1952 when a fire and explosion caused the facility to close. Activities at the site contaminated soil and groundwater. Following cleanup, EPA took the site off the Superfund program�s National Priorities List (NPL) in 1992.
