A Effluent Disposal - Downtown Area Sample Clauses

A Effluent Disposal - Downtown Area.  Description: Activities to support performing detailed Hydrogeologic Evaluation for one potential WWTF groundwater discharge site for the proposed Downtown Area WWTF.  Subtasks o Utilizing the previously identified site evaluation (based on site suitability, permitting, previous reports, impacts to the environmental, etc.) select the next best preferred site for further consideration with Site 1/1A and Exit 12 already under investigation. o Review of Existing Town Reports; Collect Town Site Data (BOH, DPW, etc.); Review of USGS and Other Hydrogeologic Data; Meetings with Town; Conduct Site Visits; and Prepare Health and Safety Plan. o Confirm with MassDEP the field investigation requirements for both traditional subsurface groundwater discharge and wick discharge o Prepare a Hydrogeologic Evaluation Proposal for both Subsurface and Wick Discharge; Prepare and Submit to MassDEP; Prepare Specifications and Subcontract Agreements; Prepare and Meet with MassDEP to discuss proposed Hydrogeologic Evaluation; Conduct a Site Visit with MassDEP. o Conduct Field Investigations (Oversee Drilling and Test Pit Excavation); Collect and Analyze Groundwater and Soil Samples; Perform Soils Conductivity Testing; and Analyze Field Data and Summary. o Conduct Groundwater Modeling: Modify the existing USGS Monomoy Lens Groundwater Model for site specific conditions (ie. reduce the grid size to 50 feet by 50 feet, adjust drain nodes, and adjust for geological/aquifer conditions) and Perform Groundwater Modeling Scenarios; Evaluate Groundwater Modeling Results; Evaluate Potential Impacts to Sensitive Receptors; Evaluate Nitrate Loading and Estuary Impacts; and Evaluate for Freshwater Loading. o Update Cost Estimate for Groundwater Discharge Infrastructure. o Submittal of a Groundwater Discharge Permit Application to MassDEP for review and approval.  Assumptions o Site Study - Two Trips to Town Hall and Site and One Meeting with Town; assumes site location determined by June 30, 2017. o Hydrogeologic Evaluation - Ten trips to Town Hall/Site; One meeting with MassDEP; Installation of Three to Four Monitoring ▇▇▇▇▇ (Number of ▇▇▇▇▇ Dependent on Depth to Groundwater); One Day of Test Pits; One Day Certified Soil Evaluator; and Use of USGS Monomoy Lens Groundwater Model without having to create a sub-model and no extensive redesign of model. o No fee and/or user charge for using the existing USGS Monomoy Lens Groundwater Model. o Town provides a backhoe and operator for test pits...
