Why this new program in Pennsylvania?

• Evolution of water pollution priorities
  nationwide
• Industrial operations, sewage treatment
• maintain the chemical physical, and biological
  integrity
• urban areas ? impervious cover, etc.
• Federal regulations
• 1987 Clean Water Act amendments
• EPA regulations in phases 1990, 1999
