support to train personel that operate and maintain wastewater treatment facilities

authorizes states to clean point source pollution

remove contaminents from water to ensure the health of US citizens

4. Special Conditions - Conditions to supplement effluent limit guidelines, BMPS

5. Standard Conditions - Conditions that apply to all permits and say the procedural requirments of the permit
