Implementation of the remedial work to construct the utility corridor continued during the week of June 25. To date, the excavation activities in the five and ten foot deep areas have been completed. After completion, these areas were surveyed and backfilled to surface grade in accordance with the provisions of the NYSDEC-approved work plan.
Work continued in the two foot deep excavation area to establish the soil cap. The excavation activities were completed, the limits of the excavation surveyed and construction of the two foot soil cap continues. The Remedial Contractor is expected to complete the backfilling of the area and construction of the first 18-inches of the cap on Friday, June 29.
