Pest Management and Fire Suppression Flexibility Act - Amends the Federal Water Pollution Control Act to state that the Administrator of the Environmental Protection Agency (EPA) shall not require a permit under the national pollutant discharge elimination system (NPDES), or require a State to mandate such a permit, for: (1) the proper use of a pesticide that is registered or otherwise approved for use under the Federal Insecticide, Fungicide, and Rodenticide Act; and (2) the use by or in cooperation with the Federal or State government of a fire retardant, chemical, or water for fire suppression, control, or prevention in accordance with relevant Federal guidelines; (3) silvicultural activities except for specified point source activities; and (4) the use of biological control organisms for the prevention, control, or eradication of plant pests or noxious weeds pursuant to specified provisions of the Plant Protection Act.
Redefines "point source" to exclude from the term those public health protection, pest management, and silvicultural activities excluded from NPDES permit requirements under this Act.
