Public Notice of Intent to Delete
Notice of Deletion of Sampson Horrice Site from the State Superfund Registry
The executive director (ED) of the Texas Natural Resource Conservation Commission (TNRCC or commission) is issuing this notice of deletion of the Sampson Horrice site (the site) from the state registry, the list of state Superfund sites. The state registry lists the contaminated sites which 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 site was originally proposed for listing on the state registry in the November 15, 1996 issue of the Texas Register (21 TexReg 11207). The site, including all land, structures, appurtenances, and other improvements is a former gravel pit, encompassing approximately 20 acres, located in a residential and industrial area at 2000 and 2006 Plainfield Drive in Dallas, Dallas County, Texas. In addition, the site included any areas where hazardous substances came to be located as a result, either directly or indirectly, of releases of hazardous substances from the site.
Drums of solid and hazardous wastes were accepted at the site in late 1983 or early 1984. Investigation of the site revealed that the constituents of concern (COCs) included benzene, toluene, ethyl benzene, xylene, total petroleum hydrocarbons, lead, mercury, chromium, dieldrin, aldrin, and DDT. Concurrent with the remedial investigation, a removal action was performed at the site.
A removal action began in August 1999 that included excavation, sampling, and removal of 349 drums and 200 yards of impacted soil. Verification samples were collected at the completion of the removal activities and confirmed that the remaining soils were below the TNRCC Risk Reduction Standard 2 residential standards for the COCs at the site. The excavation was then filled with surrounding clean soils, completing the removal action in January 2000.
A Certificate of Remediation, a record of TNRCC remedial activities on this property, has been filed in the real property records of Dallas County, Texas. Notice was given in the Certificate of Remediation that arsenic, chromium, lead, and mercury were detected, but at levels below the TNRCC's Standard 2 residential medium specific concentrations for soil. Future land use is considered suitable for residential purposes in accordance with risk reduction standards applicable at the time of the filing.
In accordance with 30 Texas Administrative Code (TAC) §335.344(b), the commission held a public meeting to receive comments on the intended deletion of the site. The meeting was held on Tuesday, December 4, 2001, at 7:00 p.m. at the Nancy Moseley Elementary School Auditorium, 10400 Rylie Road, Dallas, Texas.
The commission has prepared a Responsiveness Summary that responds to the comments received at the public meeting. The complete public file, including the transcript of the meeting and the Responsiveness Summary, may be viewed during regular business hours at the TNRCC Records Management Center, Building E, First Floor, 12100 Park 35 Circle, Austin, Texas 78753, telephone numbers (800) 633-9363 or (512) 239-2920. Fees are charged for photocopying file information.
In accordance with 30 TAC §335.344(c), the ED determined that the site no longer presents an imminent and substantial endangerment to public health and safety or the environment due to the removal actions that have been performed at the site.
Additionally under Texas Health and Safety Code, §361.188(d), a notice will be filed in the real property records of Dallas County stating that the facility has been deleted from the state registry.
All inquiries regarding the deletion of the site should be directed to Ms. Barbara Daywood, TNRCC Community Relations, telephone numbers (800) 633-9363 or (512) 239-2463.
