13. 13 Waste Water Treatment Plan Reductions

14. 14 Stormwater from New Development Virginia’s position is that the recently adopted Stormwater Management Regulations address nutrient pollution from stormwater associated with new development in accordance with the TMDL. If wastewater treatment capacity is not available, new development and redevelopment will be hindered.

15. 15 Local Government Consequences  Withhold Construction permits under VSMP  Impose treatment plant limits at limit of technology and existing flows, precluding new connections  Mandatory Urban Retrofits of existing urban lands (MS4 Permits)  Financial penalties for noncompliance with MS4 and other permits  Expanded regulated urban area under residual designation authority  Stricter limits/requirements on Confined and non-confined Animal Feeding Operations
