Permit Application Progress

• DEP has issued a second RAI.
• Project team members met with the NE
  District DEP permit engineers to discuss
  issues.
• Responses to second RAI scheduled to
  be submitted on December 10, 1999.
         Operations Plan
• Submittal of a detailed operations plan
  was a part of RAI 2.
• Operations plan designed to be an
  evolving document, but a basic “game
  plan” was established.
         Operations Plan
• Define project participant roles and
  responsibilities.
• Define method of communication and
  decision making.
• Define reporting requirements to DEP
  district.
• Define basic health and safety criteria.
          Operations Plan
• Define contingencies and responsive
  actions.
• Outline site inspection and maintenance
  requirements.
• Define monitoring controls for the issues
  of landfill fires, explosive conditions, and
  leachate flow.

         Operations Plan
• Outlines a series of research phases.
  – Construction monitoring.
  – Baseline monitoring.
  – Startup monitoring.
  – Construction monitoring.
       Cap Issues Paper
• A number of parties have raised
  concerns about the cap. An “issues
  paper” was prepared to address why
  the cap system was desired and to
  describe how the researchers believe
  the concerns are addressed.
