Final Certificate of Completion Achieved for Former Aransas Pass Carbon Black Plant – AOC-1
We are proud to announce the successful closure of environmental activities at the 5.3-acre Former Aransas Pass Carbon Black Plant – AOC-1, located between Rockport and Aransas Pass, Texas. The Railroad Commission of Texas (RRC) has officially issued the sixth and final Certificate of Completion for this site—a significant milestone in our long-standing commitment to environmental stewardship.
This final certificate, awarded by the RRC, follows five Certificates of Completion previously granted by the Texas Commission on Environmental Quality (TCEQ), reinforcing our track record of excellence in site investigation and remediation.
Our involvement began with a Phase I Environmental Site Assessment (ESA), which identified recognized environmental conditions related to historic oil and gas pipelines. Epperson Environmental Group then conducted a detailed investigation, confirming the presence of total petroleum hydrocarbons in the soil and groundwater. However, all levels were within the regulatory standards established by the RRC. With no further action required, we successfully secured the Final Certificate of Completion.
This achievement clears the way for future redevelopment, and we’re excited to share what’s next: the transformation of the site into a fully operational, large-scale railyard. This project will not only enhance regional infrastructure but also support sustainable, long-term industrial growth.

Dixie Electro Plating Company: A Legacy of Remediation and Resilience
The transformation of Dixie Electro Plating Company stands as a powerful example of resilience and environmental responsibility. Located on Engelke Street in Houston, this 2.5-acre property has long been a center of industrial activity, with a rich history of hard chrome and nickel plating operations.
Epperson Environmental Group (EEG) became involved when the site entered the Texas Commission on Environmental Quality (TCEQ) Voluntary Cleanup Program (VCP), initiating a comprehensive effort to address historical contamination. Investigations revealed the release of plating chemicals into the shallow groundwater near a former containment area and wastewater treatment sump.
Environmental assessments revealed the presence of cadmium, chromium, copper, lead, and nickel in groundwater at concentrations exceeding protective levels for potable use. EEG responded by installing a groundwater recovery system, which operated until sustained monitoring revealed that the groundwater plume had stabilized. This progress led to the approval of a Municipal Setting Designation (MSD) as the long-term remedy for the site.
Demonstrating our continued commitment to responsible stewardship, EEG coordinated the MSD application process with the City of Houston and worked closely with TCEQ to secure the necessary ordinance and certificate. Further site activities included waste unit closures, an Affected Property Assessment Report (APAR), and a Response Action Plan (RAP). The RAP addressed isolated soil impacts beneath the facility building footprint, which are now effectively capped by the building structure itself.
In recognition of these successful actions, TCEQ issued a conditional Certificate of Completion, affirming the site’s compliance with regulatory standards and supporting its continued industrial use.
The story of Dixie Electro Plating Company is one of proactive remediation, long-term planning, and a dedication to sustainable industrial operations. This achievement reflects EEG’s core mission and values.

Roxie Drive Redevelopment: From Industrial Past to Environmental Success
A 0.7-acre former industrial site on Roxie Drive in northwest Austin has reached a significant milestone—earning the prestigious Certificate of Completion from the Texas Commission on Environmental Quality (TCEQ).
Once used as a storage yard and warehouse for an oilfield drilling company, this property supported decades of operations, including equipment maintenance, truck fueling, and chemical storage. After the site was vacated, Epperson Environmental Group conducted a thorough investigation to assess its environmental condition and potential future uses.
Our team conducted comprehensive soil and groundwater sampling to assess the site for semi-volatile organic compounds (SVOCs), volatile organic compounds (VOCs), total petroleum hydrocarbons (TPH), and metals. The results were promising: a detailed Tier 2 risk evaluation determined that no chemicals of concern exceeded Texas Risk Reduction Program (TRRP) Protective Concentration Levels or Petroleum Storage Tank (PST) regulatory limits.
This finding led to the issuance of a final Certificate of Completion by TCEQ, officially clearing the site for redevelopment. Today, the former industrial yard stands ready to support new commercial and industrial opportunities, serving as a model for responsible cleanup and future-forward planning.
The Roxie Drive success story exemplifies how environmental diligence and expert remediation can transform legacy industrial properties into valuable assets for future generations.

Revitalizing San Antonio: The Transformation of Former Merchants Ice & Cold Storage
We proudly celebrate a significant achievement with our developer client: the successful completion of environmental remediation for a 4-acre site just east of downtown San Antonio, now recognized by the Texas Commission on Environmental Quality (TCEQ) with a Certificate of Completion.
Known as the “Former Merchants Ice & Cold Storage,” the property is steeped in history. Once home to cotton ginning and oil refining operations, the site later evolved into a cold storage and refrigeration facility. It was subsequently used for limited reuse—most recently as an entertainment venue—while much of it, including the iconic Merchants Ice building on Houston Street, remained vacant for decades.
Epperson Environmental Group partnered with the client to address the environmental challenges posed by this legacy site. A Phase I Environmental Site Assessment (ESA) identified several areas of concern, including a former machine shop in the cold storage engine room, historical underground storage tanks, and residual hazardous substances from earlier industrial uses.
Our team conducted an in-depth investigation of the soil and groundwater, culminating in the submission of an Affected Property Assessment Report (APAR) to the TCEQ. Using Tier 2 human health exposure pathway analysis, we confirmed that all contaminant levels were safely below Texas Risk Reduction Program Protective Concentration Levels. TCEQ determined that no further action was required and awarded the final Certificate of Completion.
With the site now cleared for redevelopment, plans are underway to create a dynamic multi-family residential community. The design honors the site’s heritage by incorporating portions of the existing structures, blending historic character with modern, sustainable living.
The Former Merchants Ice & Cold Storage site is a powerful example of how environmental remediation and thoughtful redevelopment can breathe new life into historic properties, transforming a once-abandoned industrial site into a thriving, future-focused neighborhood.

Old Dallas High School: Preserving History, Paving the Future
Our developer client has reached a significant milestone, securing a Certificate of Completion from the Texas Commission on Environmental Quality (TCEQ) for the iconic "Old Dallas High School" property—a 5.4-acre historic site located on Bryan Street in downtown Dallas.
Originally established as a public school in the late 19th century, the property includes a 125,000-square-foot, three-story school building with a basement, an asphalt-paved parking area, and adjacent undeveloped land. Vacant for many years, the site is now poised for a transformative future.
Environmental concerns emerged during early assessment activities, which revealed the presence of chlorinated solvents in the shallow groundwater beneath the property. In response, Epperson Environmental Group guided the client through the successful acquisition of a Municipal Setting Designation (MSD) from the City of Dallas—an essential first step in addressing potential groundwater impacts.
Following this, our team conducted a targeted investigation of historical source areas using soil and groundwater sampling. Results confirmed that all contaminant concentrations were well below the Texas Risk Reduction Program Protective Concentration Levels. With this confirmation, TCEQ issued a final Certificate of Completion, clearing the site for residential redevelopment.
Today, the vision for Old Dallas High School is one of renewal, transforming this storied landmark into a vibrant residential community that blends historical character with modern design. This project stands as a testament to the power of environmental leadership and thoughtful urban revitalization.
Join us in celebrating the continued evolution of downtown Dallas, where the legacy of the past helps shape a bold, sustainable future.

Adjacent to the railroad tracks that support the new Dallas Area Rapid Transit (DART) line to the Dallas Fort Worth Airport and close to historic downtown Plano, the 18.5-acre General Cable production plant was an attractive property for redevelopment.
General Cable operated a large wire and cable manufacturing plant at this location until the 1980s. Solvents used in the manufacturing process contributed to surface and groundwater contamination. An affected property assessment was completed and the property was entered into the VCP. Soils affected with metals and volatile organics compounds contamination were removed to residential standards and a Response Action Completion Report (RACR) was submitted to TCEQ, approved and a final certificate of completion was issued. Today the property has been subdivided into multiple transportation warehouse tenants. The owner has updated the exterior of the building and added landscaping, thereby making it a productive and attractive addition to the community.

Located at 3200 Ross Avenue in Dallas, Texas, this 1.32-acre property is an area transitioning from light industrial to mixed use residential. The site was initially developed in 1907 as a laundry and dry cleaner; it closed its doors in 1997. Underground plumes of contaminated groundwater containing chlorinated solvents originating from on-site underground storage tanks were identified beneath the site. The property was entered into the VCP and received an MSD certificate. Approximately 1,600 cubic yards of solvent contaminated soils and six underground storage tanks that had once held chlorinated solvents and diesel fuel were removed and disposed of off-site. The TCEQ issued a final Certificate of Completion and the property was sold to a local Dallas developer. Today construction is complete on a 45 new brick-and-stone residential townhome development.

Project – Affected Property Assessment, Soil Cleanup
The former 2306 Motor Street property is strategically located one-half mile from Parkland Hospital and the UT Southwestern Medical Facility, well-positioned to serve the housing needs resulting from the expansion of the hospital and the medical campus. Much of 2306 Motor Street was perceived as heavily contaminated with lead and heavy metals (from past lead battery cracking and remanufacturing activity) and from unknown activities at a former food processing plant also located on-site. The affected property assessment included an investigation of a drum storage area, oil/water separators, chemical storage above-ground storage tanks, and lead-contaminated soils from the historic battery recycling operation.
Remediation of the property began with the City of Dallas MSD ordinance and resulting TCEQ MSD certificate followed by the removal of approximately 1,200 cubic yards of lead-contaminated soils to residential use standards. TCEQ approved the RACR and then issued a final certificate of completion for the property. Today, the site is now a $30 million mixed-use development with 263 apartments and 43,000 square feet of retail space, providing housing and services to the surrounding medical community.
