Timeline
During 2015 and early 2016, we completed a significant number of pre-design activities to provide data needed to develop the Corrective Measures Implementation Plans, also referred to as CMI Plans or simply, the designs. This work included soil and groundwater sampling throughout the former manufacturing area, installation of additional groundwater monitoring wells, additional investigations in and around Landfills 1 and2 and construction of material handling facilities that will be used for all remedial areas. The ten remedial areas and the anticipated start of construction are shown on the adjacent map.
At this stage, the site remediation is anticipated to be completed by 2019. This schedule is dependent on completion of all of the designs and detailed work plans for each area in the timeframes allowed. Mallinckrodt and DEP have agreed to this schedule and are working jointly to meet the proposed deadlines, through ongoing team meetings to facilitate communication and ensure all parties stay on track to meet the projected schedule. However, as any true Mainer knows, winter can quickly throw a wrench into any optimistic plans for work during December through March.
A key component of any large remediation project is planning a realistic schedule that takes into account the numerous steps from design to completion and addresses the inter-dependencies of each activity. The remediation at the Orrington Site has been divided into ten separate components and detailed schedules for each must be prepared well in advance to ensure designs and work plans are submitted to DEP with enough time for appropriate review and discussions. Then, when a final design is agreed upon, contractors are evaluated, requests for bids are sent out to these contractors, a contractor is selected and construction and restoration can be completed in the appropriate season.
