OU-1 Use of a Presumptive Remedy Question: What is a presumptive remedy Answer: Preferred technologies for common categories of sites (e.g., landfills) Presumptive remedies streamline the remedy selection process (i.e., removal not considered as an option) Evaluates technologies that are best suited for the site Ensures consistent selection of remedial actions Landfill sites must exhibit “appropriate” characteristics for applicability of a presumptive remedy (e.g., type of waste, volume, low risks/hazards) 55
