  There are a few changes to Alabama’s new Blue Book.  One change is the recommendation of a “standing pool” for a Sediment Basin.  This would be the water (minimum 1 foot) left in the bottom of the sediment basin pool when the skimmer can no longer skim the surface water. It is also sometimes called a sediment storage zone.  A standing pool can be achieved, either by setting your skimmer discharge pipe higher, or by creating an elevated platform for the skimmer to rest on.   By using the platform method , you can move the skimmer over and allow the basin to completely drain if needed.   Some may be concerned with a standing pool attracting mosquitos; however it has been found that sediment basins do not attract mosquitos as they do not like muddy water. Also, research has found that the standing pool of water helps to minimize resuspension of captured sediment when the next storm event causes runoff into the basin.    Perry L Oakes, PE Erosi...

  The First Clear Water Alabama Award of Excellence was presented at the recent Clear Water Alabama event in Daphne. The award is given to a project in Alabama that exemplifies the principles of erosion and sediment control on a construction site.   The Award was presented to the Alabama DOT Project US98/SR158 Corridor.   While the project got off to a shaky start in 2007, it wound up being a model for ALDOT work and led to the development of the Five Pillars of Construction Stormwater Management.   (Pictured left to right are Dr. William Puckett, Executive Director of The Soil and Water Conservation Committee, Sam Fountain, Construction Engineer SW Region of ALDOT, and Tony Cooper, Stormwater Coordinator for the SW Region of ALDOT.)   Perry L Oakes, PE Erosion and Sediment Control Program Coordinator AL Soil and Water Conservation Committee
