The Shenandoah River and it's tributaries have been under assualt from many different points and sources for the last 20 years and this is one area (storm water managment and construction runoff) that is woefully behind the times. The mainstem of the Shenandoah River, from Riverton Dam to Warren Dam is a virtual dead zone due to runoff and heavy silt that has accumulated over the decades. The current regulations do not even meet the requirments of the Federal Clean Water Act, let alone show common sense and good stewardship of the land and our waters. I urge that these regulations be brought up to date using the "best practices " standards that will help improve and sustain our waters.
