Program Responsibilities

The OLQ Engineering & GIS Services Section provides engineering technical support for the Remediation programs for the Office of Land Quality.

Specific Services

  • Evaluates proposed remedial technologies and systems for contaminated sites
  • Evaluates Work Plans, Corrective Action Plans (CAPs), Operation & Maintenance Plans
  • Evaluates Cost Studies/Analyses and Feasibility Studies
  • Provide engineering field services by overseeing construction activities and remedial system operations
  • Technical assistance

Reference List

The following list contains references used by OLQ Engineering when providing technical support for other office of Land Quality (OLQ) sections or projects. Use of any reference in this list does not pre-approve or pre-qualify a remediation related proposal as valid, and does not necessarily speed, expedite, or change OLQ administrative or technical review procedures. The list is not comprehensive but is a general starting point for the most common engineering subjects reviewed by OLQ Engineering.
