Wet Weather Quality Act of 2000

Wet Weather Quality Act of 2000 - Amends the Federal Water Pollution Control Act to require each permit, order, or decree issued pursuant to such Act for a discharge from a municipal combined storm and sanitary sewer to conform to the Combined Sewer Overflow (CSO) Control Policy signed by the Administrator of the Environmental Protection Agency (EPA) on April 11, 1994, and to provide for long-term control plans to meet water quality standards as expeditiously as possible. Directs the Administrator to report to Congress on progress made by EPA, States, and municipalities in implementing and enforcing the CSO control policy.

Authorizes the Administrator to provide technical assistance and grants for treatment works to carry out pilot projects relating to specified areas of wet weather discharge control. Authorizes appropriations.

Permits the Administrator, in any fiscal year in which at least $1.2 billion is available for grants to States for water pollution control revolving funds, to make grants to States or municipalities for planning, design, and construction of treatment works to intercept, transport, control, or treat municipal CSO and sanitary sewer overflows. Gives priority for grants to certain applicants, including municipalities that are financially distressed communities. Requires the Federal share of the cost of activities funded by such grants to be at least 55 percent. Authorizes and allocates appropriations. Requires the Administrator to report periodically to Congress on the recommended funding levels for such grants.

Directs the Administrator to report to Congress on: (1) the extent of health and environmental impacts caused by municipal CSO and sanitary sewer overflows; and (2) the resources spent, and technologies used, by municipalities to address such impacts. Requires the Administrator to maintain a clearinghouse of technologies for addressing such impacts.
