A Phase II Investigation completed at the W. Church Street property owned by the city of Grand Prairie indicated a release had occurred from the underground storage tanks formerly located on the property. Subsequently, a Leaking Petroleum Storage Tank (LPST) investigation was completed by W&M which demonstrated that, although gasoline constituents were present in groundwater above TCEQ Action levels, there were no unacceptable risks to human health or environmental receptors. The LPST case received closure from TCEQ in August 2011.
W&M conducted Phase I ESAs on four properties in 2007 and 2008 for Ann Grimes as part of the Brownfields Assessment Grants from the EPA for the investigation of Brownfields properties within the City. As part of the program, the City partners with local property owners to perform environmental assessments of their property as one of the tools to evaluate environmental issues and promote redevelopment. W&M conducted utility line replacement through a former landfill site.
W&M conducted Phase I ESAs and Phase II investigations of several properties owned by various industries, including TXU Energy Company in Fort Worth, Tarrant County, Texas. The properties are located in an area being redeveloped by the Tarrant County College District (TCCD) for their downtown campus. The area is heavily developed with a number of industries and potential sources of contamination including several landfills, two power plants, a lead smelter, former gasoline stations and a residential community. The TCCD campus is considered an anchor for the downtown redevelopment project known as the Trinity River Vision.
The Phase I and Phase II ESAs indicated that the Site had been impacted by VOCs and metals. As a result, W&M completed the Innocent Owner/Operator Programs (IOP) application, conducted soil and groundwater sampling, worked with the TCEQ case coordinator, and completed the IOP report documentation (namely the Site Investigation Report or SIR). The sampling and data evaluation by W&M clearly demonstrated to the TCEQ that the Site had not "caused or contributed" to the contamination and the Site was subsequently granted Innocent Owner Certificates (IOC) for several properties. Other contaminated properties were granted closure through the VCP after submitting the appropriate Affected Property Assessment Reports (APARs) and conducting additional investigation or remediation.
The Sites were issued the appropriate regulatory closure certificates and the properties are currently undergoing development. The downtown campus and the Trinity River Vision are considered very important developments for the future of downtown Fort Worth. The project was completed in a timely manner and within the proposed budget. W&M’s expertise with the TCEQ at similar IOP and VCP sites was very helpful in the successful completion of this project.
W&M conducted Phase I Environmental Site Assessments (ESAs), Phase II Investigations, asbestos surveys, removal of Petroleum Storage Tanks (PSTs), remediation services, regulatory closure at a number of properties at a former electric power generation facility. W&M effectively worked with the TCEQ to obtain regulatory closure certificates for several properties in a heavily developed area of downtown Fort Worth. The downtown campus and Trinity River Vision are considered critical for the future of the area. W&M completed the projects on time and within the proposed budgets. W&M’s expertise with the TCEQ at similar sites was instrumental in the successful completion of this project.
W&M has worked with the City of Plano on several projects beginning in 2000. Our work with the city has included Phase II Investigations, removal of a PST, and remediation/closure of the Tri-City (Plano, Richardson, and Garland) gun range. The gun range was impacted by lead and was entered into the TCEQ’s Voluntary Cleanup Program (VCP). W&M completed the VCP documentation, decontaminated the gun range, and remediated impacted soil. We utilized Tier II calculations to increase the cleanup concentration for soil lead and substantially decreased the costs for excavation and off-site disposal. This site has received a Final Certificate of Completion from the TCEQ.
W&M has had a long-term relationship with Greenway (local real estate developer) to perform a wide range of environmental projects including Phase I ESAs, Phase II Investigations, asbestos inspections, remediation projects, and site closures through the TCEQ VCP and Innocent Owner Program (IOP). Our work has included several challenging sites such as the former Exide battery facility on Motor Street (part of City of Dallas Brownfields project), former Alcatel facility in Richardson, and Gaston Avenue property (former dry cleaners that was granted a Municipal Setting Designation [MSD] by the City of Dallas). The MSD was utilized to close the site without long-term and very expensive groundwater remediation. W&M designed the response actions at this site and assisted the client with bidding support and contractor selection. W&M has closed a number of Greenway sites.
W&M has a long history of working with AT&T on a wide range of projects dating back to 1998. Our work with AT&T has included Phase I ESAs, Phase II Investigations, removal of PSTs, closure of LPSTs through the TCEQ PST program (reimbursable and non-reimbursable sites), site remediation, and use of soil vapor extraction (SVE) as a treatment method. W&M has successfully worked with AT&T to become one of their prime contractors in Texas and surrounding states.
The W&M staff has worked with the DHA to remove a leaking PST, evaluate paint samples for lead-based paint (LBP), conduct Phase II Investigations, and evaluate/close site through the TCEQ VCP. W&M is currently working with the DHA to close their maintenance facility through the TCEQ VCP. The facility was impacted with an on-site leaking PST (LPST) and off-site chlorinated solvents (co-mingled plume). W&M has also worked with DHA to assess and remediate their former Superfund site.
W&M Brownfields assisted investors in the acquisition of a contaminated property in downtown Dallas, through a limited liability corporation, at a discounted price. A Municipal Setting Designation (MSD) application and other environmental services were provided to the investors in return for equity in the property. The property was leased to a neighboring manufacturer to provide income to the investors while awaiting full regulatory closure. This property is currently for sale.
W&M completed a thorough Site inspection that included plotting the exact location of all current and former oil and gas wells using a GPS. Field data was overlaid with Railroad Commission of Texas (RRC) well data to determine the accurate number of active, plugged, and abandoned wells at the Site. W&M identified eight main oil field areas during the Site reconnaissance. Based on Site conditions, W&M developed an environmental liability cost estimate.
