are sealed with blind flanges and will not be altered in this Task Order.

Existing diffuser assemblies on the last two (2) 12" differser risers are to be 2.

removed and replaced with new assemblies.

New diffuser assemblies are essentially the same as existing with the 3.

addition of elastomeric Duckbill Diffusers at each discharge location.

Diffuser assemblies consist of 12" Carbon Steel Tees, 45s, 90s, Orifice Plates, and Duckbill Diffusers. All connections between exisitng pipe risers, Tees, 45s, 90s, Orifice Plates and Duck Bills shall be made with ASTM Flanged connections and gaskets.

All Carbon Steel components to be coated with marine paint per 4.

specifications.

All hardware to be Super Duplex Stainless Steel.5.
