Fact Sheet

September 2005

Site Deleted from National Priorities List
Red Oak Landfill, Red Oak, Iowa

INTRODUCTION

The Environmental Protection Agency (EPA) has deleted the Red Oak Landfill Superfund site from the National Priorities List. The site was added to the National Priorities List, or NPL, in 1989. The NPL is a list of hazardous waste sites in the country. The Iowa Department of Natural Resources (IDNR) concurs with this action. The Notice of Deletion was published in the Federal Register on July 26, 2005. A 30-day comment period followed.

BACKGROUND

The Red Oak Landfill Superfund site is located approximately 1.5 miles north-northwest of the Red Oak city limits in Montgomery County, Iowa. The site is bounded on the west by Parkwest Road and on the east by the East Nishnabotna River. Originally the site of a limestone quarry, the property was purchased by the City of Red Oak and operated as a landfill from 1962 to 1974. Hazardous materials found at the site include volatile organic compounds (VOCs), such as toluene and xylene, and heavy metals such as chromium, lead, and mercury.

The site was placed on the National Priorities List in March 1989. After completion of a remedial investigation and a feasibility study in 1992, EPA presented the preferred remedy to the public and signed a Record of Decision (ROD). Subsequently, EPA modified the ROD in a document known as an Explanation of Significant Differences. The selected remedy consists of installing a cap or cover on the landfill to limit water infiltration and prevent exposure through direct contact. The remedy also includes fencing the site, groundwater monitoring, taking measures for slope protection, and imposing deed restrictions on the property.

SITE ACTIVITIES

The site has been addressed through Federal, State, and potentially responsible parties’ actions. These actions included the following:


DELETION ACTION

EPA and IDNR have determined that all appropriate actions under Superfund have been completed. The clean-up actions at the site were successful in preventing exposure to wastes and contaminated soils on the surface of the site by the chosen remedy of capping.

Since hazardous substances were left on the site, five year reviews will be conducted. The first five year review was conducted in 2002, and showed that the remedy was protective of human health and the environment.
