![]() ![]() The remainder of the core can be excluded from further analysis. Cores will be separated into two segments, a segment homogenized over the project depth and a segment representing the next six inches to be exposed after dredging.Definitions of dredging and sampling depths. Plan to drive cores one foot below project depth.Identify locations for core sampling using the guidance for identifying core sampling locations.Determine the number of core samples to be collected based on the total area to be dredged using the Balduck's Method.Identify the locations of outfalls or other known sources of pollution, including historical spill areas.Determine the total area to be dredged and the total volume of sediment to be removed.Use a recent (e.g., less than 6 months old) bathymetric survey of the project site.Prepare a plan view of the proposed dredge area, including project depth. ![]() This is part of the reference PDF available. The following steps should be taken in designing an approvable sediment sampling plan. ![]() Staff can address problems and concerns relating to the application, the design of the sediment sampling plan, and analysis of sediment samples.įor reference, the Checklist, Flowchart, and Balduck's Method table are available in a PDF. ![]() The applicant is encouraged to contact NYSDEC Region 2 at any point during the sediment sampling plan design phase and the application process. A flowchart has been provided to allow the applicant to easily follow the sediment sampling plan process. Designing a Dredging Sediment Sampling and Analysis Planīy following this guidance and TOGS 5.1.9 In-Water and Riparian Management of Sediment and Dredged Material (PDF), as appropriate, applicants proposing to dredge should be able to create an approvable sediment sampling plan. ![]()
