Compliance

For those sites associated with recognized environmental conditions, and determined by testing to be impacted with chemicals or constituents regulated under certain state and/or federal programs, we offer services designed to manage these sites through clean-up or administrative closure. Our staff is trained and experienced in keeping up with frequently changing administrative/legislative program requirements as well as hydrology/hydrogeology, engineering technology, process design, computer-based modeling, and remediation technologies.

• Barge Maintenance Facility (Houston Ship Channel, Channelview, Texas)
  As a result of former disposal of waste paint and asbestos upon this industrial property by site employees, TGE successfully remediated these concerns to the satisfaction of the TCEQ and under their review. Following extensive trenching and excavation efforts, TGE determined the location, volume, and character of the waste, worked with the regulatory authority to evaluate closure options, and remediated all regulated waste from the site by excavation and off-site disposal.
  
  

• Steel Plant and Industrial Coatings Operation (Houston, Texas/Ship Channel)
  Due to expansion, this former 50+ acre industrial plant was purchased to off-load imported steel and manufacture raw coat material for sale. As a result of re-development, much of the site suffered compressor oil leaks and extensive PCBs contamination. TGE worked with the USEPA self-implementation program for purposes of delineating shallow soil impact and presented an APAR to the TCEQ for review and comment. This facility will require remediation to meet goals of the VCP/TCEQ program, the design of which is pending.
  
  

• Industrial Multi Use 1900's Warehouse (Houston, Texas)
  In the true sense of “brownfield” redevelopment, TGE investigated, characterized and remediated this multi-use, inner-city industrial warehouse property following preliminary determination by others that the site was impacted by organic and inorganic constituents. TGE installed a series of soil borings and groundwater monitoring wells, closed abandoned automobile and metal manufacturing/plating facility equipment (lifts, tanks and sumps/grit traps), and removed/excavated shallow impacted soil. TGE characterized/delineated sub-surface impacted soils and shallow groundwater under state programs. Corrective action at this property involved asbestos abatement, demolition of certain site structures, and closure of the site under risk-based corrective action (and deed restriction of this property) for industrial use with engineering controls.
  
  

• Former Quarry/Landfill/Steel Plant - Brownfield/Commercial Re-Development (Miami, Florida)
  During re-development of a master-planned, 100 acre, Class A+ project, TGE identified areas of impact to the environment (including petroleum and solvent impacted soil), tested associated areas of concern via the installation of monitor wells/soil borings, and removed (by excavation) impacted media prior to re-development of this site for commercial use. TGE worked closely with the state regulatory agency to meet project objectives and continued to monitor groundwater until final closure.
  
  

• Solvent Manufacturing Facilities (Houston, Texas)
  TGE became involved with this client when it outgrew one facility, associated with known solvent impact, and opted to purchase a second plant with existing (although unknown) contamination. Following investigation and eventual purchase of the alternate site, TGE took both facilities through investigation, characterization and remediation phases within associated state programs. Both sites were impacted with uncommon constituents of concern which required unique discussions with the state regarding clean-up values in order to meet closure. Both sites are currently in the VCP program and will be closed under “risk”/administrative means.
  
  

• National Banking Institutions (Houston, Texas)
  During recent bank “branching” projects, TGE worked extensively with a number of financial institutions to develop more than 10 branch banks upon former gasoline service stations, dry cleaning facilities and auto repair garages within busy metropolitan areas. Working within state and federal programs, the staff of TGE designed and operated remediation systems beneath branch banks and included engineering controls (such as liners) to reduce risk of possible vapor infiltration into these buildings. These re-development projects promoted re-use of real property which would have otherwise been abandoned.
  
  

• Former Cattle Rendering Plant (Abilene, Texas)
  Following comprehensive assessment of this 20+ acre facility and placement of a series of groundwater monitoring wells to various depths so as to delineate the limits of petroleum and solvent impact, TGE managed this project to near closure via the state PST and VCP programs under natural attenuation monitoring following product recovery. The project is under final review by the state and will require closure of two industrial supply wells near the subject property in order to meet desired closure criteria.
  
  

• Former Industrial Cleaning/Barge Maintenance Facility (Port Arthur, Texas)
  Following industrial use of this facility over a period of 50+ years and coupled with accidental discharge of sludge waste upon the ground surface by others hired to clean up the site following shut down, TGE became involved in site efforts designed to comply with a TCEQ agreed order. As such, TGE completed extensive soil characterization by conducting a series of soil borings for delineation purposes and performed remediation (by removal) of impacted soil and wastes from the site. This project is pending final closure and successful completion, per TCEQ program requirements.
  
  

• Industrial Steel Manufacturing Facility (Houston, Texas)
  Following site characterization via soil and groundwater assessment, this property was subject to remediation of surface and subsurface soil via the TCEQ VCP program. TGE successfully identified, calculated and negotiated certain background concentrations for inorganic compounds of concern and removing select areas of soil impacted by organic constituents (solvent and petroleum hydrocarbons) from the property. Areas of the site formerly affected were allowed to be re-developed and utilized without restriction.
  
  

• Plastics Manufacturing Facility (Southeast Texas)
  Following issuance of fines and penalties for wastewater and storm water discharge of regulated constituents to state waters, TGE conducted environmental efforts designed to characterize and remove wastes generated as a result of site activity. This work was conducted in concert with compliance efforts and permitting for this industrial facility.
  
  

• Various Automobile Dealerships and Auto Maintenance Facilities
  With TGE’s work in representing automobile dealerships, needs for remediation of underground storage tank concerns as well as waste management areas (such as sumps, oil/water separators, underground lifts and maintenance garages) have routinely arisen. This work has been an outgrowth of due diligence projects, site closures and removal of regulated materials and wastes to maintain compliance with state and federal programs. TGE recently began several projects within the TCEQ TRRP program throughout Texas.
  
  

• Former Chemical Manufacturing Facility (Houston, Texas)
  TGE assisted in addressing surficial/compliance-oriented concerns related to spills and releases of regulated constituents to the environment (ditches, surface soils, etc). Following characterization (testing) of such spills and materials, TGE instituted appropriate means of removal and off-site disposal to the satisfaction of both state regulators and the client.
  
  

• Plastics Manufacturing Facility (Reno, Nevada)
  Due to the purchase of a “pre-contaminated facility”, TGE evaluated and managed remediation efforts related to this chlorinated solvent-impacted plastics manufacturing facility. Current efforts involve ongoing operations and maintenance of the treatment system, periodic reporting to the local/state authority and communication of this information to client for consideration of closure.
  
  

• Numerous Commercial and Industrial Petroleum Storage Tank Facilities (Throughout Texas, Oklahoma, Florida and Other Areas)
  For various petroleum storage tank owners and operators, and often following PST compliance efforts, TGE conducted numerous site characterization and clean-up (remediation) projects which achieved closure under state programs. These projects involved premeditation efforts ranging from minimal soil removal following tank retrofit to comprehensive design and system installation for removal of product.
  
  

• Former Warehouse Distribution And Grocery Facility (Beaumont, Texas)
  TGE investigated subsurface conditions at this abandoned warehouse prior to purchase of the facility. Following installation of a series of monitoring wells and soil borings, it was determined that a large hydrocarbon plume and free-phased product exists which migrated onto adjacent properties, including the interstate right-of-way. TGE is currently involved in removal of measurable product and closing this site through the state PST program with natural attenuation and ground water monitoring.
