Notice of Intent to Delete (Delist)
The executive director of the Texas Natural Resource Conservation Commission (TNRCC or commission) is issuing this public Notice of Intent to Delete (delist) the Solvent Recovery Services (SRS) State Superfund Site (the Site) from the State Registry, the list of state Superfund 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 commission is proposing this deletion because the executive director has determined that the Site no longer presents such an endangerment, due to the removal actions that have been performed at the Site.
The Site, including all land, structures, appurtenances, and other improvements, is located at 5502 Highway 521, about 0.2 mile south of the intersection with Highway 6, in Arcola, Fort Bend County, Texas. The Site also included any areas where hazardous substance(s) had come to be located as a result, either directly or indirectly, of releases of hazardous substance(s) from the Site.
About 0.5 acre of the five-acre site was used for recycling of waste paint solvents from 1976 to 1984. The current property owner bought the property in March 1983. Operations ceased in late 1984 when the facility was closed due its inability to meet the Resource Conservation and Recovery Act financial assurance requirements. Closure of the facility began in 1986, but was never completed by the operator.
The operations at the Site consisted of a 3,000 square foot concrete pad, three spent-solvent recovery tanks (total volume of 24, 000 gallons). The distillation units consisted of one 1,300-gallon tank and two 50-gallon condenser tanks.
In 1989, the SRS Task Force (comprised of companies that sent waste to the facility) began an investigation. The investigation involved installing groundwater monitoring wells, and sampling and analysis of soils, waste materials, surface water, and groundwater. Phase I of the Remedial Investigation (RI) was completed in 1990 and determined that the waste materials and soils contained elevated levels of several metals, and volatile and semivolatile compounds.
Removal actions were conducted in 1991. All materials originally on-site were removed as part of the removal actions. The materials consisted of the concrete pad, and the waste consolidation area on the concrete pad, surrounding soils, two tanks of waste sludge, decontamination liquids, and several 55-gallon drums.
Based on the results of Phase I of the RI and the removal action, an Administrative Order (AO) was executed in April 1995. The AO identified the chemicals of concern (COCs), required a Phase II of the RI and preparation of the Feasibility Study (FS). During Phase II of the RI, buried containers were discovered. The containers were removed and additional sampling of the remaining soils and sediments was conducted. A review of the results indicated that no surface or subsurface soils exceeded the residential cleanup levels.
Numerous rounds of groundwater sampling from six monitoring wells were conducted during Phase I of the RI, Phase II of the RI, and during preparation of the FS. The analytical results indicated that no COCs were detected at levels that exceeded the groundwater cleanup levels. Since the soils and groundwater met the cleanup levels, the FS recommended no further action for the soils and groundwater.
The following is a list of reports documenting the remedial investigations and removal action activities: 1.) Solvent Recovery Services Site, Remedial Investigation Report, September 1990; 2.) Removal Action Report, Solvent Recovery Services Site, Arcola, Texas, March 1995; 3.) Phase II Remedial Investigation Report, Solvent Recovery Services State Superfund Site, Arcola, Texas, March 2000; and 4.) Final Feasibility Study Report, Solvent Recovery Services State Superfund Site, Arcola, Texas, June 2001.
Based on the results of the RIs, removal actions, and the FS previously described, the Site does not pose unacceptable excess risk to human health or the environment, and no further remedial action is warranted at the Site. The Site is appropriate for residential use according to state risk reduction regulations applicable to the Site as of October 10, 2001.
Contaminants deposited on the Site were removed to meet the residential soil criteria established by 30 Texas Administrative Code (TAC) §335.555 (Risk Reduction Standard Number 2). The groundwater investigation showed that the concentrations of COCs met the residential exposure conditions and, therefore, no action was needed. As a result of the removal actions that have been performed at the Site, the executive director has determined that the Site no longer presents an imminent and substantial endangerment to public health and safety and the environment. Therefore, the Site is eligible for deletion from the State Registry as provided by 30 TAC §335.344(c).
In accordance with 30 TAC §335.344(b), the commission will hold a public meeting to receive comment on this proposed deletion. This meeting will not be a contested case hearing within the meaning of Texas Government Code, Chapter 2001. The meeting will be held at 7:00 p.m., on Thursday, December 6, 2001, at the City of Arcola City Hall, 13222 State Highway 6, Arcola, Texas, and will consist of two parts: an informal discussion period and a formal comment period.
All persons desiring to make comments regarding the proposed deletion of the Site 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 December 6, 2001, and sent in writing to Mr. Alvie L. Nichols, Project Manager, TNRCC Superfund Cleanup Section, Remediation Division, MC-143, P. O. Box 13087, Austin, Texas 78711-3087. The public comment period for this action will end at the close of the public meeting on December 6, 2001.
A portion of the record for the Site, including documents pertinent to the executive director's proposed deletion, are available for review during regular business hours at the Missouri City Branch Library, 1530 Texas Parkway, Missouri City, Texas 77489, telephone number: (281) 499-1511. The complete public file may be obtained during regular business hours at the commission's Records Management Center, Building D, North Entrance, Room 190, 12100 Park 35 Circle, Austin, Texas 78753, telephone numbers: (800) 633-9363 or (512) 239-2920.
