UST Quality Assurance Program Plan (QAPP)

On July 1, 2011, the Underground Storage Tank (UST) Management Division implemented a Quality Assurance Program Plan (QAPP). The goal of the QAPP is to formalize procedures that will provide accountability and quality control for the data collected at UST sites.

Contractors must complete and submit Appendix B of the QAPP (Contractor Addendum) when requested for site-specific scopes of work (e.g. groundwater sampling and monitoring well installation). The UST Management Division will request the QAPP Addendum when an appropriate scope of work is determined to be necessary.
