Guidance & Documents

ITRC publishes and produces guidance documents and training courses that help state environmental agencies and others gain valuable technical knowledge and develop consistent regulatory approaches for reviewing and approving specific technologies. These include technical overviews, case studies, and technical and regulatory guidance documents. See the latest ITRC Product List, Updated in July 2023, for a list of all of ITRC's published products. 

These documents are written and reviewed by teams of environmental professionals, including state and federal environmental regulators, federal agency representatives, industry experts, community stakeholders, and academia. All ITRC documents undergo a rigorous external review, and all external comments and team responses are captured and posted to the team ITRC Connect community. ITRC will consider a lack of response during the 45-day external review period to signify no serious objection to the content within the product.
