Public Notice of Intent to Delete
NOTICE OF DELETION OF THE PERMIAN CHEMICAL COMPANY 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 Permian Chemical Company state Superfund site (the site) from its proposed-for-listing status on 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 July 16, 1993, edition of the Texas Register (18 TexReg 4709). The site, including all land, structures, appurtenances, and other improvements, is approximately 30 acres in size, and is located at 325 Pronto Ave., Ector County, Texas, approximately three miles east of downtown Odessa. In addition, the site included any areas where hazardous substance(s) came to be located as a result, either directly or indirectly, of releases of hazardous substance(s) from the site.
Dorchem, Inc. began operations at the site in 1977, operating as a chemical plant, manufacturing hydrochloric acid (HCl) as the primary product and potassium sulfate (K2 SO4 ) as a byproduct. Permian Chemical Company acquired the site in 1981 and continued the Dorchem operations. Permian Chemical Company abandoned the site in 1987.
The Remedial Investigation/Feasibility Study (RI/FS) examined the analytes for soil, sediment and groundwater including pH, sodium, potassium, sulfate, chlorides, heavy metals, volatile organic constituents (VOCs) and petroleum hydrocarbons. Due to the deteriorated condition of the overhead process structures, a removal action was initiated at the site in September 1996. A second phase of the RI at the site was conducted in October/November 1999. The purpose of this second phase was to determine if any on-site soils could be contributing to the low levels of VOCs detected in some site monitor wells, and to plug and abandon the on-site water wells.
Following the completion of the RI at the site, a Baseline Risk Evaluation (BRE) Report was prepared. The results of the RI and site-specific exposure scenarios were used to complete the BRE. This evaluation was completed in August 2000. Based on the results of the BRE, the site does not pose unacceptable excess risk to human health or the environment.
The TNRCC determined that hazardous and Class I industrial solid wastes remained at the site, therefore, a second removal action was initiated in November 2000. This removal action included removal of all hazardous and Class I wastes from the site, and transportation to an approved waste disposal facility, for proper disposal.
In May 2001, the TNRCC concluded that no further action was appropriate for the site. However, the site is not appropriate for residential use according to state risk reduction regulations in effect as of September 2, 1999, and has been deed recorded for commercial/industrial use only.
In accordance with 30 TAC §335.344(b), the commission held a public meeting to receive comments on the intended deletion of the site on February 28, 2002, at the Ector County Library, Rotary Room, 321 West Fifth Street, 2nd Floor, Odessa, Texas. No comments regarding the proposed deletion were received at the public meeting. The complete public file, including a transcript of the public meeting, may be viewed during regular business hours at the commission's 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.
Pursuant to 30 TAC §335.344(c), the ED has 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.
In accordance with Texas Health and Safety Code, §361.188(d), a notice will be filed in the real property records of Ector County, Texas stating that the site has been deleted from the state registry.
All inquiries regarding the deletion of the site should be directed to Ms. Janie Montemayor, Community Relations, telephone numbers (800) 633-9363 or (512) 239-3844.
