PROJECT STATUS: The Contractor continued to progress the project in accordance with the approved construction schedule, but there have been delays due to high water. The following activities occurred during this quarter: • Initial project mobilization (field office set-up and establishment of an equipment staging area). • Completed clearing and grubbing items. One on-site spoil area was approved by EIC and CEC. • On-site detour installed with minor change in alignment to address site distance problem at adjacent driveway. • Completed demolition of existing bridge. Contractor intends to start pile driving for new abutments within the next 10 days.

COMPLIANCE WITH SPDES PERMIT The appropriate erosion and sediment control items were installed for this stage of the project. Installation of these items was generally in accordance with the details shown in the project plans. Modifications to the E&SC plan to account for changes in the detour alignment were documented in the Site Log Book. • There were no site visits by state or federal regulatory agencies. • There were no known violations of the SPDES Permit. • The SWPPP was amended to include the restoration plan for the on-site spoil site. • EIC denied a request from an adjacent landowner for clean spoil material to fill in a low (wetland) area. • Conducted 9 standard seven day site inspections. • Conducted 2 storm-related site inspections. (19mm and 12mm rain events)

INDIVIDUAL SWPPP COMPONENTS The project is currently in Stage 1 of the Erosion Control Plan shown on Sheet 18 (Drawing EC-1). All erosion and sediment controls are in place per this plan. A summary of adjustments, modifications and maintenance issues include:

• Added pay item for Vegetation Protection Barrier to protect shrubs in front of a historic house. • Inspected all seeded and mulched areas. All areas were in good condition and required no maintenance. • Directed contractor to repair a 6 meter section of silt fence toppled by sediment during a large storm event. Added a temporary swale diversion and 2 stone check dams up gradient of silt fence to slow water velocity. • Waterway diversion item was used during installation of the temporary detour and for bridge demolition. Contractor used an 8" pump and settling basin which worked well. Work was completed and the diversion was removed before the two storm events.
