Wetlands

W&M has worked with Imperium Holdings during their acquisition of large tracts of undeveloped lands in the North Texas area to delineate wetlands and waters of the U.S. and to prepare a 404 permit application and obtain 401 water quality certification for impacts during development.



Remediation and VCP Closure of Gun Range

The Tri-City Firing Range, located in Plano, Texas (Site), has been utilized for police officer training purposes since its construction in the 1980s. Lead was identified in the soil on the property and sediments of an adjacent creek bed. W&M entered the Site into the TCEQ VCP, conducted soil and groundwater sampling to delineate the impact, developed the required VCP documents, completed limited soil excavation and off-Site disposal, and received final closure through the VCP.

On-Site sampling identified shallow surface soil impacts and only limited impacts to the sediment in the creek. No groundwater impact was identified at the Site. Once the Site was delineated, W&M developed a Response Action Plan (RAP) that was approved by the TCEQ and quickly completed by excavation and off-Site diposal. W&M determined that the Site could be closed under Remedy Standard A with and alternative cleanup level utilizing a transport model to verify determine a Tier 2 Protective concentration Level and thereby increasing the cleanup level from 15 mg/kg (State background for soil lead) to 500 mg/kg. This process allowed W&M to perform less remediation and, thereby, substantially decrease the remediation costs associated with this project. The project was completed on-schedule and on-budget even when additional tasks were requested by the City of Plano.



Burlwood, LLC

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.



Dallas Housing Authority

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.



Greenway Investment Co.

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.



City of Plano

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.



Texas Pipeline Company

W&M conducted a wide range of environmental assessments for a large pipeline company at compressor stations located throughout Texas, Louisiana, Alabama, Georgia, South Carolina, and North Carolina. Our work at these compressor stations ranged from Phase I ESAs, Phase II Investigations, and remediation of impacted soil associated with condensate and waste materials disposed into on-Site pits. Remediation tasks included remedial design, development of project work plans, contractor oversight, working with the state and local regulators, and confirmation sampling.



Battery Recycler, North Texas

W&M has worked on a wide range of projects at a secondary lead smelter in North Texas (hazardous waste Transfer, Storage and Disposal facility). Our work has included Phase II Investigations, remediation of impacted soil, soil sampling to evaluate air monitoring impacts, development of SWP3 plan and annual updates, spill prevention, control and countermeasure (SPCC) plan development, source reduction/waste minimization (SR/WM) plan, assistance with their Environmental Management System (EMS) plan, completion of their TPDES permit, and design and contractor oversight of landfill cell construction.



Cable Manufacturer, Plano

W&M performed a wide range of environmental services for this former copper wire manufacturer while it was still in operation and after it was shut down and ultimately sold to a real estate investor. W&M provided a full range of environmental services to this facility while it was still in operation including development of their SWP3, SPCC plans, asbestos surveys, Petroleum Storage Tank (PST) management, removal and closure of Leaking PSTs (LPSTs), and general regulatory assistance (e. g., waste classification). Following plant shut down, W&M assisted the client with Phase II sampling, remediation of impacted soil, and closure through the TCEQ Correction Action Program. The Site has been cleaned up and closed and ultimately sold to an investor.



Former Battery Disposal Facility

W&M assisted potentially responsible parties (PRP) in the closure of former battery disposal facility in Palmer, Texas. This site contained approximately 20,000 cubic yards of battery casing chips and other battery related waste materials. W&M conducted field investigations to delineate the environmental impacts, developed a site closure acceptable to the TCEQ, prepared plans and specifications to implement closure plan, assisted with selection of remediation contractor, and performed confirmation sampling and regulatory coordination. The remediation plan consisted of a RCRA-type solid waste management unit (SWMU) consolidating on-site waste materials and impacted soils. The SWMU was capped using on-site clay and the site was issued a VCP Final Certificate of Completion. W&M significantly reduces site closure costs by keeping the wastes on site (no off-site disposal) and utilizing Tier II calculations to minimize on-site excavation volumes.
