crater resources, inc./keystone coke co./alan wood steel co.


The Crater Resources, Inc./Keystone Coke Co./Alan Wood Steel Co. site, located in Upper Merion Township, Montgomery County, Pennsylvania, consists of four inactive quarries on a 95-acre parcel of land. Beginning in 1919, the Alan Wood Steel Company disposed of wastes generated by its coking facility in Swedeland, Pennsylvania, into three of the quarries (Quarries 1, 2, and 3). In 1977, Alan Wood Steel declared bankruptcy and transferred ownership of the property to Keystone Coke Company, a subsidiary of Alabama By-Products Corporation. Keystone Coke Co., continued to dispose of wastes in Quarry 3 until 1980. In 1979, Haploid Corporation purchased part of the property and later transferred a portion of Quarry 3 to Crater Resources, Inc. and other portions to Swedeland Road Corporation. Swedeland has since transferred its land holdings to several other parties. Various organics and tar wastes were disposed of in Quarry 1 from 1918 to 1965 via a pipeline from the Alan Wood Steel coking facility. Quarry 2 was filled with similar wastes as well as solid wastes, including cinders, bricks, and paint cans. Quarry 3 was used as the main disposal quarry, receiving waste ammonia liquor (WAL) directly from the coking facility via pipeline. Quarry 3 received organics and tar wastes until 1980; three ponds filled with water remained in the quarry until the 2010 cleanup work started. Quarry 4 was mined for sand and gravel and later backfilled with construction debris. Public wells within four miles of the site supply drinking water to area residents. The nearest of these wells is within one- mile of the site, with the majority of the surrounding population served by public water.
