ITRC Project Teams produces guidance and documents to help the environmental community gain valuable technical knowledge and develop consistent regulatory approaches for reviewing and approving specific technologies. These documents are written and reviewed by teams of environmental professionals from ITRC’s diverse membership groups and affiliations.
All ITRC documents undergo an external review period. ITRC considers a lack of response during the 45-day external review period to signify no serious objection to the content within the product.
