Join us on May 30, 2019 for our Soil and Groundwater Remediation Technology Selection webinar. David McAlister will discuss how specific conditions and motivations surrounding a soil and groundwater remediation project can affect the technology selection process. A wide range of technologies for this type of remediation exist, but the combination of multiple technologies or (more…)

It’s Like Groundhog Day All Over Again!

 In honor of Groundhog Day this February, I’m going to describe a “normal” trip that I take on a semi-regular basis.  I received a call from a relatively small manufacturer that was having some environmental issues and received W&M’s name from a contractor that they use.  They asked if I’d come out to take a look.  I happily obliged. Most facilities I visit have many similarities and this facility wasn’t an exception.  On the grounds are a couple of big steel buildings, substantial amounts of concrete in the front, and the rear of the property is largely bare ground.  The steel buildings usually have a crane or two; there is equipment manufactured for oil and gas, shipyards, off-shore platforms, or pipeline facilities.  Some facilities make items for all of these types of industries while some only make items for a single industry. On a typical visit, the same thing happens:

Too Many Cooks in the Kitchen?

Keeping your project on track when you have stakeholder involvement You’re an environmental manager for your company, and you learn that a contractor doing repair work has caused a release from one of your pipelines which is located on private property.  You report the spill to the authorities, notify the landowner, and initiate cleanup activities.  The contractor files a claim with their insurance carrier. Following initial response actions, soil and groundwater is investigated and cleanup goals are established.  It sounds straightforward until the various stakeholders get involved.  The stakeholders include the construction contractor, their insurance company, the insurance company’s consultant, the regulatory agency, and the landowner, in addition to you and your environmental consultant.  All parties want the spill cleaned up but have different goals and objectives. In another case, no one knows exactly when the spill, or multiple spills, occurred, but the cleanup has been underway for years. Initial

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.



Environmental Services for TCCD Downtown Fort Worth

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.



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.



AT&T

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.



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.



Dallas County

Our staff worked with Dallas County District #6 to address contaminated soil along Interstate IH-30 in Balch Springs, Texas. The subject property was adjacent to a gasoline service station and had been impacted with petroleum hydrocarbons. The impact had stopped development of a planned subdivision and specifically the utilities along the highway access road. W&M conducted Phase II sampling at the site, designed plans and specifications for modifications to the buried utilizes, and provided general consulting services to Dallas County to complete this project.



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.
