Guidance & Documents

ITRC publishes and produces documents that broaden and deepen technical knowledge and expedite quality decision-making when faced with environmental challenges. These include technical overviews, case studies, and technical and regulatory guidance documents.

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.

With private and public sector members from all 50 states, the District of Columbia, and Puerto Rico, ITRC documents provide a national perspective.

(SRR-1)

Sustainable Resilient Remediation (SRR) is an optimized solution to cleaning up and reusing a hazardous waste site that limits negative environmental impacts, maximizes social and economic benefits, and creates resilience against increasing threats. The objective of this SRR guidance is to provide resources for regulators, stakeholders, consultants and responsible parties to help integrate sustainability and resilience practices into remediation projects.

(HCB-1)

Cyanobacteria are microscopic, photosynthetic organisms that are found naturally in all aquatic environments. Under certain conditions, cyanobacteria can multiply and become very abundant, discoloring the water throughout a water body or accumulating at the surface; these occurrences are known as blooms. This ITRC guidance discusses key aspects of harmful cyanobacterial blooms management that waterbody managers and other interested parties should consider as they respond to these events.

(ISM-2)

This updated Incremental Sampling Methodology (ISM-2) web-based document builds upon the 2012 version (ISM-1) and reflects advancements in technology in the ensuing eight years.  ISM-type investigation methods have evolved, and regulators have gained more experience in the application of ISM in the field and in the laboratory. The original 2009 survey of regulators and industry environmental experts was updated with current information on ISM practices to measure progress and understand what obstacles are still being encountered.

This document is formatted as a website that is not meant to be printed. You can access the web document at any time from the ITRC website or you can bookmark the link. If you would like to print, please enter the document website and then use the "Print" button to print. Some of the web-based documents allow you to print either the entire document or a subsection.

The updated document includes multiple examples of site scenarios for DU designation and the collection of ISM samples under different field conditions. A separate section on the use of ISM investigation methods to support human health and ecological risk assessments has been added and the simulations in the original appendices have been updated and include a recent study on Student t and Chebyshev discussion of UCL. Current case studies are summarized to provide insight into the potential applications, benefits, and challenges of the approach from recent sites.

(PFAS-1)

This Interstate Technology and Regulatory Council (ITRC) online document includes the PFAS Technical and Regulatory Guidance Document, PFAS Fact Sheets and Explainer Videos, Training Module Videos and external tables of data and information prepared by the ITRC PFAS Team. The document is designed specifically to support state and federal environmental staff, as well as others (including stakeholders, project managers, and decision makers), to gain a working knowledge of the current state of PFAS science and practice. The web-based nature of this document lends itself to updating of key information in this rapidly evolving subject. It is the intention of ITRC to periodically update the document as significant new information about PFAS develops. The guidance document can be downloaded as a PDF.
