Please go forward with substantive regulations for the plasticulture industry, especially as it applies to the VA eastern shore.  I have lived on the shore for 16 years, own a small farm, and live at the headwaters of Jacubus Creek. I have personaly observed the humongous sediment runoff from plasticulture fields to tidal streams, and clouds of wind blown sediment from these same fields during the winter, if they have been cultivated, but not seeded with cover crop, or not tilled in the fall before freeze-thaw events in both Accomac and Northampton counties. I have also observed, from the ground, and from the air, "temporary drains" cut through field-edge berms following heavy rain events, with massive sediment runorr to adjacent tidal streams. Not all growers who use plastic mulch employ careless, lowcost tactics, but those who do are destroying the quality of the aquatic environment in the tidal streams adjacent to their fields. The best management practices for plasticluture , published by VA tech several years ago--"Protecting water quality: Best management Practices for row crops grown on plastic mulch in Virginia"  Mary Leigh Wolfe et all, 2002 provides good guidance .
