Environmental Site Remediation

Environmental Site Remediation


Remediation refers to the processes and actions required to transition a contaminated site from the investigation phase to a site closure status with the State regulatory agency. As such the term encompasses a wide spectrum of services ranging from human and ecological exposure risk assessment to removal and disposal of contaminated materials or treatment of affected groundwater.


In the State of Texas, the overarching program administered by the State’s environmental agency, the Texas Commission on Environmental Quality (TCEQ) is known as the Texas Risk Reduction Program (TRRP). EPI’s professionals are qualified to provide geological, hydrogeological, modeling, regulatory standards comparison, and remediation alternatives to their clients for an expeditious transition to the site closure status. Some of the programs under the TRRP that EPI’s professionals have direct experience in include the following:

  • Voluntary Cleanup Program (VCP)
  • Innocent Owner/Operator Program (IOP)
  • Ready for Reuse Program (RfR)
  • Sites that are under corrective action order from the regulatory agency


EPI also provides a full range of environmental assessment and remediation services related to the oil and gas industry, which is administered by the Texas Railroad Commission. These programs mirror the remediation regulations administered by the TCEQ but are related to existing and historical oil and gas production sites and both active and abandoned pipelines and transmission stations.
