ST. AUGUSTA SANITARY LANDFILL/ENGEN DUMP

EPA ID# MND981002256
Last Updated: September, 2006

Site Description

The St. August Landfill / Engen Dump is located in St. Augusta Township, Stearns County, Minnesota. The site is bounded by the Mississippi River on the northeast, Johnson Creek on the southeast, Interstate Highway 94 on the west, and privately-owned land to the south and the north. The Engen Dump consists of two areas that are approximately 11- and 8 -acres in size. The St. Augusta Landfill comprises approximately 16 acres. A borrow pit that was used to provide cover material for the St. Augusta Landfill is located on the northern side of the landfill. Landfill operations were conducted at the dump and landfill between 1966 and 1982. The site was the primary waste disposal site for the St. Cloud area during this time. The Engen Dump began to receive municipal, commercial, and industrial wastes in 1966. The industrial wastes disposed of at the dump, consisted of ground glass, solids and sludges, paper pulp waste, ash, and small amounts of cutting oils, coolants, solvents, paints, and cleaning compounds. The dump was phased out of operation between 1971 and 1972, and portions of the dump were covered with onsite soils. In June 1985, the site was given a score of thirty-four under the Superfund program Hazard Ranking System (HRS) score. 

Site Responsibility

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

Threats and Contaminants

Groundwater is contaminated with heavy metals that include arsenic, barium, and lead; volatile organic compounds (VOCs); atrazine; and phthalates. Health threats include coming into direct contact with and ingestion of contaminated groundwater. 

Cleanup Progress

A September 1992 groundwater investigation and feasibility study (FS) was prepared under a request for response action, issued by the Minnesota Pollution Control Agency (MPCA) in 1993. The recommendation under the request for response action was no further action. No further response action was appropriate, because a closure plan was prepared and executed for the landfill as part of the Solid Waste Disposal Facility Permit, issued by MPCA. No final record of decision (ROD) was issued on the site. In 1994, the legislature of the State of Minnesota enacted the Landfill Cleanup Law, authorizing MPCA to assume responsibility for future environmental response actions at qualified landfills that have received notices of compliance. A notice of compliance was issued by MPCA for the St. August Landfill/Engen Dump site on May 8, 1995. MPCA has since assumed all responsibility for the St. August Landfill/Engen Dump under the act. Therefore, no further response actions under federal law were appropriate. Consequently, the United States Environmental Protection Agency deleted the site from the National Priorities List in November 1996.  A preliminary close-out report was signed on June 6, 2000, documenting that all construction was completed.  A five-year review was conducted for this site in 2003. The remedy remains protective of human health and the environment.
