Scoping is the initial planning phase of the Remedial Investigation/Feasibility Study (RI/FS) process. Many of the planning steps begun here are continued and refined in later phases of the RI/FS. Scoping activities typically begin with the collection of existing site data, including data from previous investigations such as the preliminary assessment (PA) and site inspection (SI). On the basis of this information, site management planning is undertaken to:

  • preliminarily identify boundaries of the study area;

  • identify likely remedial action objectives and whether interim actions may be necessary or appropriate; and

  • establish whether the site may best be remedied as one or several separate operable units.

Once an overall management strategy is agreed upon, the RI/FS for a specific project or the site as a whole is planned. Typical scoping activities include:

  • Initiating the identification and discussion of potential Applicable or Relevant and Appropriate Requirements (ARARs) with the support agency. (see Terms of Environment)

  • Determining the types of decisions to be made and identifying the data and other information needed to support these decisions.

  • Assembling a technical advisory committee to assist in activities, serve as a review board for important deliverables, and monitor progress during the study.

  • Preparing the work plan, sampling and analysis plan, health and safety plan, and community relations plan.
