    2. Stormwater Runoff Pollutes the Natural Environment

    4. Impacts of Polluted Stormwater Runoff Polluted stormwater runoff is a leading cause of impairment of the nearly 40% of surveyed U.S. water bodies. Stormwater pollution causes flooding and the degradation of habitat for aquatic life. In the Chesapeake Bay watershed, storm water runoff is responsible for impairments in over 1,570 river miles and 44 square miles of estuarine waters. Over 10,000 stream miles have been degraded by past development, with major impacts to aquatic life in watersheds with as little as 10% land development.

    5. Construction Sites Produce A High Volume of Sediment Rate of erosion is greater per acre on urban construction projects

    6. Inadequate Staffing Maryland regulations require that each active site be inspected for compliance on the average of once every two weeks. MDE is only able to visit 18% of the construction sites in areas under their jurisdiction due to inadequate staffing. (MDE 2007 Annual Inspection Compliance Report)

    7. Sedimentation the process by which the eroded particles are transported and deposited It is important to know the difference between the process of erosion and the process of sedimentation. It is important to know the difference between the process of erosion and the process of sedimentation.

    8. Types of Erosion on Construction Sites (1)

    9. Types of Erosion on Construction Sites - Illustrated

    10. Splash Erosion Erosion by water is a process of breaking loose and transporting soil particles. The energy of raindrops falling on denuded or exposed soils is the key element. The annual impact of raindrops, for instance, has been estimated to average approximately 30 billion foot-pounds or the equivalent of 10 thousand tons of T.N.T. per square mile. Once the soil particle is detached, it is picked up by overland flowing water. Erosion by water is a process of breaking loose and transporting soil particles.

Once the soil particle is detached, it is picked up by overland flowing water.

    11. Sheet Erosion As the velocity of overland flowing water increases, additional soil particles are detached and transported causing sheet erosion. Sheet erosion involves the uniform detachment of soil particles by a thin layer of water flowing across the surface referred to as sheet flow. Sheet erosion is often somewhat gradual and sometimes can be difficult to detect.

    12. Rill Erosion Water flowing over land has a tendency to concentrate. This creates small channels, or rills. Rills occur mainly on recently disturbed and exposed soils.

    13. Gully Erosion Rills that continue to receive concentrated flows can eventually turn into gullies of varying widths and depths. The distinction between a rill and a gully is one of depth. A gully is sufficiently deep that it would not be obliterated by normal tillage operations, whereas a rill is of lesser depth and would be smoothed by use of normal tillage equipment.

    15. How Do We Fix the Problem?

    16. Making It Happen There are four steps to execution. Identify a site, evaluate it, report on it, and then conduct follow-up to re-evaluate and report non-compliance again as needed. It is therefore an iterative process. This training will help you go through all of these processes. Specifically, we will help you identify construction sites, identify and evaluate a sites best management practices, and then reporting those non-compliant situations effectively to developers and government officials so that those situations can be remedied.There are four steps to execution.

    17. Finding Problems

    18. Monitor Construction Activities In Your Watershed What to watch for: Zoning notices and hearings Site clearing activities Other activities suggesting large development Muddy water flowing down streets Encourage the class participants to take an active role in protecting their own watershed from sedimentation pollution.

    19. Maryland Law Environment Article Title 4, Water Management, 4-413 It is unlawful to add, introduce, leak, spill, or otherwise emit soil or sediment into waters of the State or to place soil or sediment in a position or location likely to be washed into waters of the State
