Update - Week of April 3, 2017

Site Work

National Grid and its contractors are mobilizing to the former Dangman Park MGP site ("site") to begin the New York State Department of Environmental Conservation (NYSDEC)-approved In-Situ Treatment Interim Remedial Measure (IRM).  The work the week of April 3, 2017 will be hand clearing injection locations. 

The In-Situ Treatment IRM will include the placement of gypsum slurry into the ground at approximately 50 locations.  Gypsum dissolves into sulfate, which is used to enhance naturally occurring biological degradation of petroleum hydrocarbons in groundwater.  The In-Situ Treatment IRM is anticipated to take about four weeks to complete.

Building construction work is being conducted by the property owner. The building construction work is beyond the limits of planned remediation at the site or will otherwise not interfere with the completion of the required IRMs at the site.

Update on Remediation Plans

National Grid, under the oversight of the NYSDEC, is proposing a cleanup for the site located at 486 Neptune Ave, Brooklyn, NY.  The remediation proposed is comprised of two Interim Remedial Measures (IRMs) – one In-Situ  IRM and one Excavation IRM.  The NYSDEC-approved In-Situ IRM is being completed as described above.

National Grid recently completed the IRM Premobilization Investigation.  This work involved test pits and soil borings that were required for the design of the Excavation IRM.  Now that the data has been collected, National Grid will complete the design for the Excavation IRM, and will submit additional documents in April 2017 to NYSDEC for approval.  The Excavation IRM will be completed at the Site in 2017.
