Remediation of Soils and Dry Sediments at RVAAP 08-11 (LLs 1-4)
Page 3-1
3.0 CONSTRUCTION ACTIVITIES
This section details construction tasks that were undertaken to implement the remedial actions at
LLs 1-4. These activities were performed in accordance with the Final Interim ROD
(Shaw 2007a), the RAWP (Shaw 2007b) and the associated management and field plans (Shaw
2004e, f; 2006a-h; 2007c) to ensure the cleanup goals and specific environmental protection
requirements during construction activities were met.
3.1 PREMOBILIZATION
Prior to mobilizing to the RVAAP, Shaw acquired the required permits, planned and coordinated
traffic routes, performed a pre-construction survey, identified any remaining utilities, and
conducted a pre-construction meeting with the RVAAP Team members.
3.1.1 Required Permits/Clearances
Shaw personnel verified that all applicable permits, notifications, and approvals had been
obtained prior to mobilization. Special attention was made to ensure activities to be performed
near environmentally sensitive areas were coordinated with the OHARNG, the RVAAP Facility
Manager, and the Ohio EPA in accordance with Federal, State, and local regulations. Before
commencing construction activities, Shaw filed a Notice of Intent (NOI) for Coverage under the
Ohio EPA General Permit, Ohio EPA Permit No. GPOHC000002, for authorization for storm
water discharges associated with construction activity under the National Pollutant Discharge
Elimination System (NPDES). Per the requirements of the General Permit, a Storm Water
Pollution Prevention Plan (SWPPP) (Shaw 2007c) was submitted to the Ohio EPA and Portage
County Soil and Water Commission prior to construction activities.
Prior to the intrusive subsurface activities, Shaw coordinated utility clearances at LLs 1-4 with
PIKA International, Inc. (PIKA), the RVAAP operating contractor, and the Ohio Utilities
Protection Services (OUPS). The OUPS representative reviewed information and resources
available for the facility and verified that there were no live utilities present at any of the areas
that Shaw anticipated to perform intrusive activities.
3.1.2 Traffic Coordination and Routing
Shaw established transportation routes for incoming and outgoing vehicles and heavy equipment
to minimize the impact to the RVAAP and surrounding community. The proposed truck routes
reflected the shortest egress from the load lines to the primary roadway (State Route 5) wherever
possible. Haul routes were positioned to minimize the removal of mature vegetation or
encroachment on wetland areas.
3.1.3 Pre-Construction Survey
A preconstruction survey was performed to document initial conditions at each of the load lines
and along the roadways of the intended haul route at the RVAAP. The pre-construction survey
included a detailed inspection of existing conditions following demolition activities at LLs 2-4
and of the primary road surfaces that Shaw anticipated using a minimum of several weeks before
