Scope of Work and Cost Proposal for Beck's Lake NPLILaSalle Park Area August 6, 2018 Page 3 of 8 Task 3 - Soil Management Plan Implementation and Waste Soil Disposal: An EPA -approved Soil Management Plan (SMP) is currently in place for construction activities specifically associated with the expansion of the Charles Black Recreation Center located in a six -acre portion of the southwest corner of the LaSalle Park property. The soil disturbance activities covered under the existing SMP include installation of building footers, utility trenches, removal of pavement, and installation of dry wells and connection piping via trenches. An SMP Addendum is currently under review by the EPA for select construction activities across the entire Beck's Lake/LaSalle Park property. The activities addressed by the SMP Addendum include; demolition of an old pavilion and construction of a new pavilion, removal of an old slide and installation of a new slide, installation of two drinking water fountains, installation of an irrigation system for the soccer fields, and several landscaping activities across the park. Each of these activities will involve soil disturbance. As part of the SMP Addendum (as with the existing SMP), during soil disturbance, the atmosphere in the work zone will be monitored for dust due to the potential for various contaminants of concern to be inhaled by the construction workers. Should soil disturbance result in visible dust or the dust monitor is triggered by a threshold exceedance, dust control measures will be implemented. In addition, any soil that is removed from the ground must be stockpiled and secured onsite pending offsite disposal arrangements. Soil samples must be collected for waste characterization analysis at a rate of one sample per each 500 cubic yards accumulated. It is estimated that 800 tons of stockpiled soil will need to be properly disposed (costs of which are included in the task cost estimate). All backfill material must be verified as clean based on laboratory analysis. Task 4 - General Consulting Services: Where appropriate and as requested by the Project Coordinator, costs have been included for JPR personnel to provide professional services related to on -going tasks where select JPR staff have prior site -specific experience on an as -needed basis as assigned by the Project Coordinator following approval of the PRPs to assist with various activities including on -going and future deliverables per the project schedule, SMP Addendum finalization, and field and analytical data interpretation. SCHEDULE The Project Coordinator, acting on behalf of the PRPs, will determine a date for implementation of the field services. It should be noted that prior to such date (minimum of48 hours), Indiana Utility Services must be contacted as required by Indiana Law for the locating of existing member utility service lines. Upon mobilization, JPR anticipates completion of the waste delineation will require two days of Geoprobe work; pending circumstances beyond our control (i.e. obstructions, collapsing borehole, non recovering
