Wastewater Treatment Plants - Discharges - Requirements

HB 1621 requires wastewater treatment plants processing over 50 million gallons of effluent daily to monitor discharges for hormones, PFAS chemicals, and bacteria, and publicly post daily bacterial levels and incident reports (like overflows) on their websites within 24 hours. It establishes bacterial safety thresholds requiring immediate public alerts when exceeded and bars non-compliant plants from Maryland's Water Quality Trading Program. Smaller plants (under 50 million gallons daily) must report staffing plans annually instead of daily data. The bill mandates transparency through public websites and gives the Department authority to enforce these requirements.
