Anchor Kit to include  

•           40lb/18kg Danforth type galvanized steel anchor with safety wired galvanized shackle

•           8ft/ 2.43mX 3/8” (10mm) galvanized steel chain lower rode.

•           60ft /  18m X 5/16” galvanized cable upper rode with thimbles.

•           Buoy – standard 15” / 38 cm inflateable

•           6ft / 1.82m x 5/16” galvanized cable printer rope with thimble and SS shackle.

Additional criteria to be met

•           Sections of curtain will not exceed 200 feet and be provided in various lengths (ft) such as 20-, 50-, or 100-feet sections to meet the total length needed for projected test scenarios requiring up to 500 ft. of curtain. 50- and 100-feet sections are preferred.

•           Minimum type III containment curtain with zipper and Velcro sealable seams between sections of curtain or acceptable alternative to minimize water seepage or leakage at seams.  Overall design of the curtains is to prevent loss of water in containment treatment scenarios to maximize retention of dye (mimicking pesticide) to research and develop the lowest possible water exchange rate over time. 

•           Curtains must be able to be exposed to pesticides (label dependent concentrations) and red rhodamine WT dye (NSF compliant).  This list of pesticides or chemicals is not all inclusive; but are the typical chemicals used for the treatment of invasive mussels and aquatic plants.  Pesticide Active Ingredients: Copper, Potash Ash (Potassium Chloride (KCL), Potassium hydroxide (KOH), Potassium Sulfide (K2SO4), 2,4-D, Endothall, Diquat, Glyphosate, Fluridone, Peroxides, Triclopyr, Imazapyr, Carfentrazone, Penoxsulam, Imazamox, Flumioxazin, Bispyribac, Topramezone, Sethoxydim, Florpyrauxifen, Chlorine, Zequanox, and Ultraviolet light (UV-B and UV-C).

•           Curtains need to be able to be deployed in place for up to 30 to 45 days, with minimal routine maintenance and limited placement adjustment.  Curtains put in place need to be able to withstand 1-fo EL/F PAN 025048 SUPPLY RUFFWATER SCREEN AND TURBIDITY CURTAIN ot fluctuations of reservoir pool elevations and be able to adjust depth of curtains to try to match the contour of river/cove bottom (reefing type system).  Projected deepest depth of site for test scenarios is 17 feet.  Recommend curtains being 18 to 20 feet depth.

•           Optional: Curtains should have screen windows and be able to be constructed at various sizes and locations (near top, bottom, or middle) within the curtain to meet the needs for slow release of containment area and suitable to be tested for filtering of dye, to mimic pesticide, with either an activated carbon type/screen or acceptable alternative.

•           Curtains will be provided in a field sealable container like a Connex box with adequate size to house the curtains and all its necessary components.

•           Vendor shall provide a final proposed development designs with the PDT team prior to manufacturing of the curtain.
