Sewage Right-to-Know Act and Well Contamination Reporting

What This Bill Does

  • Repeals and replaces existing rules about sewage treatment plant reporting requirements.
  • Requires operators of sewage treatment plants or collection systems to submit electronic reports within two hours of any spill or bypass.
  • Requires public notification through social media and direct alerts when spills or bypasses impact water bodies or the general public.
  • Establishes a real-time public notification system for sewage spills and bypasses, allowing people to sign up for text message or email alerts.
  • Requires an annual report on sewage spills by the Department of Energy and Environmental Protection.

Who It Names or Affects

  • Operators of sewage treatment plants and collection systems
  • The public who may be affected by sewage spills or bypasses
  • Local officials responsible for informing their communities about such incidents

Terms To Know

Limits and Unknowns

  • It is unclear how the real-time public notification system will be implemented or funded.
  • The effectiveness of community canvassing in case of well contamination remains uncertain without specific details.
