HW Quality Assurance

Quality Assurance Project Plan (QAPP)

The Hazardous Waste section’s updated Quality Assurance Project Plan (QAPP), approved by EPA Region 9 on December 7, 2015, describes how regulated facilities and their contractors, independent laboratories, and Hazardous Waste section staff work together to ensure that waste management and regulatory decisions are made based on environmental data of known quality and scientific validity. The plan provides guidance for regulated facilities, their contractors, and independent laboratories to ensure that their quality assurance and quality control planning and documentation meet Hazardous Waste section standards. It includes:

  • Field data sheet and chain of custody form templates which can be used by regulated facilities and their contractors when taking samples
  • References to additional guidance documents linked below and live in-text links to additional resources
  • Clickable navigation table of contents
  • Glossary of key quality assurance terms
