15 Inner Harbor Navigation Canal Lock Replacement Delays Inner Harbor Navigation Canal Lock Replacement Delays H Delays with the analysis of the samples l 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.

16 Inner Harbor Navigation Canal Lock Replacement Delays Inner Harbor Navigation Canal Lock Replacement Delays H Florida Avenue Bridge Construction l 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.

17 Inner Harbor Navigation Canal Lock Replacement Path Forward Inner Harbor Navigation Canal Lock Replacement Path Forward H Traffic analysis sent for ITR to be completed by 15 September H Public Comment Period to begin 15 October H Complete SEIS by Dec 2008

18 Inner Harbor Navigation Canal Lock Replacement Future Contracts Inner Harbor Navigation Canal Lock Replacement Future Contracts *Contracts to be completed when the enjoinment is lifted* H Coast Guard Demolition H West bank Levee Phase 1 H Resume Lock Design
