1. All waters which are currently used, or were used in the past, or may be susceptible to
use in interstate or foreign commerce, including all waters which are subject to the ebb
and flow of the tide;
2. All interstate waters including interstate wetlands;
3. All other waters such as intrastate lakes, rivers, streams (including intermittent streams),
mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or
natural ponds, the use, degradation or destruction of which could affect interstate or
foreign commerce including any such waters:
(I) Which are or could be used by interstate or foreign travelers for recreational or other
purposes; or
(ii)(From which fish or shellfish are or could be taken and sold in interstate or foreign commerce;
or
(iii) Which are used or could be used for industrial purposes by industries in interstate
commerce;
4. All impoundments of waters otherwise defined as waters of the United States under this
definition;
5. Tributaries of waters identified in paragraphs (s)(1) through (4) of this section;
6. The territorial sea;
7. Wetlands adjacent to waters (other than waters that are themselves wetlands) identified in
paragraphs (s)(1) through (6) of this section; waste treatment systems, including
treatment ponds or lagoons designed to meet the requirements of CWA (other than
cooling ponds as defined in 40 CFR 423.11(m) which also meet the criteria of this
definition) are not waters of the United States.
So to be clear, this means that tributaries of intermittent streams and wet meadows are considered to be waters of the united states and subject to the CWA. The drainage ditch along the road could be considered an intermittent stream, and thus the small flows of water on the street are tributaries, no?
See, it depends how zealous they wanna get.
