Notice of a Public Meeting on August 24, 2010, in Coahoma, Texas Concerning the Moss Lake Road Groundwater Plume

The purpose of the meeting is to obtain public input and information concerning proposal of the Moss Lake Road Groundwater Site (Site) to the State Superfund Registry and the identification of potentially responsible parties.

The Texas Commission on Environmental Quality (TCEQ) is required under the Texas Solid Waste Disposal Act, Texas Health and Safety Code, Chapter 361 et seq., as amended (the Act), to annually publish a state registry that identifies facilities that may constitute an imminent and substantial endangerment to public health and safety or the environment due to a release or threatened release of hazardous substances into the environment. The most recent State Superfund Registry listing of these facilities was published in the September 18, 2009, issue of the Texas Register (34 TexReg 6464).

Pursuant to the Act, §361.184(a), the TCEQ must publish in a newspaper of general circulation in the county in which a facility or area is located and in the Texas Register a notice of intent to list the facility or area on the state registry. With this publication, the TCEQ hereby gives notice of an area that the executive director determined eligible for listing, and which the executive director proposes to list on the state registry. This publication also specifies the general nature of the potential endangerment to public health and safety or the environment as determined by information currently available to the executive director. This notice of intent to list this area was also published on July 16, 2010, in the Big Spring Herald.

The area proposed for listing is the Moss Lake Road Groundwater Site, located in the vicinity of North Moss Lake Road, east of the city of Big Spring, north of Interstate Highway 20, in Howard County, Texas. The geographic coordinates of the Site are 32.278972 North and 101.371755 West. The description of the Site is based on information available at the time the Site was evaluated with the Hazard Ranking System (HRS). The HRS is the principal screening guide used by the TCEQ to evaluate potential, relative risk to public health and the environment from releases or threatened releases of hazardous substances. The description may change as additional information is gathered on the sources and extent of contamination.

The Site is designated as a contaminated groundwater plume originating from unknown sources where hazardous substances may have been released to the aquifer. Releases of hazardous substances to the groundwater pathway are the major concern for this site and the Ogallala Aquifer is the aquifer of concern. The primary chemical of concern evaluated for this HRS documentation record is tetrachloroethene, also known as tetrachloroethylene, perchloroethene, or perchloroethylene (PCE).

The Site is a PCE groundwater plume of unknown source, located four miles east of the city limits of Big Spring in Howard County, Texas. The Site is underlying North Moss Lake Road, north of Interstate Highway 20 in a predominantly residential/agricultural area. In the vicinity of the Site, the groundwater is used primarily for drinking and irrigation. The static groundwater levels are at a depth of approximately 40 feet. Groundwater ingestion by residents from private drinking water wells represents the most significant risk to human health. Based on sample results, 13 domestic water wells have been identified as having PCE concentrations above background levels and are identified as wells of concern. All of these wells of concern draw from the Ogallala Aquifer.

A public meeting will be held at 7:00 p.m., on Tuesday, August 24, 2010, at Coahoma High School, 606 North Main Street in Coahoma, Texas. The purpose of this meeting is to obtain additional information regarding the Site relative to its eligibility for listing on the state Registry and to identify additional potentially responsible parties. The public meeting is not a contested case hearing under the Texas Administrative Procedure Act (Texas Government Code, Chapter 2001).

All persons desiring to make comments may do so prior to or at the public meeting. All comments submitted prior to the public meeting must be received by 5:00 p.m. on August 23, 2010, and should be sent in writing to Ms. April Palmie, Project Manager, TCEQ, Remediation Division, MC 143, P.O. Box 13087, Austin, Texas 78711-3087, or by facsimile at (512) 239-2450. The public comment period for this action will end at the close of the public meeting on August 24, 2010.
