West Orange WEHI preliminary report

While the Task Force reviewed documentation specifically and exclusively for the Filtrexx Compost sock product, several other manufacturers offer products that are very similar in function in that they utilize a porous, woven tube filled with filter media (of differing kinds) to filter and strain out soil from sheet flow runoff. Therefore in order to maximize the efficiency of the product review and approval process adopted by SSCC in 2014 ( included in the beginning pages of the 2014 NJ Soil Erosion and Sediment Control Standards), and to make the greatest number of products available to the regulated public, I am issuing Technical Bulletin 2014-1.0 which allows the use of any tube or ‘sock’ product which has a three dimensional filter media design. It is not specific to any particular filter media. Filter tube or sock products proposed for use must be designed, installed and maintained in compliance with the Sediment Barrier Standard, as well as manufacturer-specific design or installation requirements. All appropriate installation details must be included on plan detail sheets and the product must be graphically denoted on the plan sheet where it will be installed. It should be noted that in no case is any form of sediment barrier permitted to be installed across a channel (so-called ‘check dams’) which is designed to convey runoff. If there is a concern that the channel design as proposed may erode, then the channel should be immediately stabilized or redesigned so as to be below the erosion threshold for that soil type. If you have any questions about the bulletin or the implementation of filter tube products, please feel free to contact me. Thank you again for your continued efforts to protect New Jersey’s soil and water resources.
