Silviculture Regulatory Consistency Act - Amends the Federal Water Pollution Control Act (commonly known as the Clean Water Act) to prohibit the Administrator of the Environmental Protection Agency (EPA) from requiring a permit under national pollutant discharge elimination system permitting requirements for a discharge resulting from the conduct of any silvicultural activity, such as nursery operations, site preparation, reforestation, thinning, prescribed burning, pest and fire control, harvesting operations, surface drainage, or road use, construction, and maintenance, from which there is runoff. Specifies that nothing in this Act exempts silvicultural activity from permit requirements for the discharge of dredged or fill material into navigable waters.
