Delays

• Delays with the analysis of the samples
• MVN and EPA Region VI developed a list of
  "Contaminants of Concern" that may pose an
  ecological risk to aquatic organisms when present
  in sediments. The contractor had trouble meeting
  the required detection limits and further testing
  methods had to be implemented to meet detection
  limits.

Delays

• Florida Avenue Bridge Construction
• In the 97 EIS we made the assumption that the
  State was going to replace the Florida Avenue
  Bridge. In the midst of our analysis it was
  determined prudent to assume the bridge would not
  be constructed due to funding problems. Therefore
  the traffic and noise impact models had to be
  recreated.
