1.1 Existing guidance on the management of investigation-derived waste is focused upon cuttings, purge water, personal protective equipment, and other miscellaneous solid waste generated at property that may be impacted by the release of hazardous materials and hazardous substances. These hazardous substances include, but are not limited to, heavy metals, petroleum, petroleum byproducts, solvents, polycyclic aromatic hydrocarbons, organic and inorganic corrosives, radioactive material, and explosives. Guidance on the management of investigation derived waste generated at sites that may be impacted by releases of perfluoroalkyl and polyfluoroalkyl substances (PFAS) is limited. This standard guide addresses this deficiency

1.2 This guide describes best practices for managing investigation-derived waste associated with PFAS that are consistent with federal and state policies and regulations at the date of issuance. The user is advised to determine if new regulations or rules have been promulgated by the state, federal, or tribal regulatory agency having jurisdiction over the property.

1.3 This guide describes considerations to prevent the unintended and unauthorized disposal of liquid investigation-derived waste that may contain PFAS into wastewater treatment plants or systems that are not permitted to receive these waste streams.

1.4 This guide describes considerations to prevent the unintended and unauthorized disposal of solid investigation-derived waste that may contain PFAS into landfills or other solid waste disposal facilities that are not permitted to receive these waste streams.

1.5 This guide describes several stormwater pollution prevention best management practices applicable to investigation-derived waste.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
