SB 117 Maryland Senate · 2025 Regular Session

Environment - Bay Restoration Fund - Septic System Upgrade Program

SB 117 establishes a program to fund upgrades of septic systems using nitrogen-removal technology through Maryland's Bay Restoration Fund. The Department of the Environment must evaluate and rank these technologies based on nitrogen reduction effectiveness, total cost (including operation), and cost per pound of nitrogen removed. Funding prioritizes failing septic systems in the Chesapeake Bay Critical Area, nitrogen-impaired water bodies, and systems threatening public health or water quality, with grants covering up to 100% of upgrade costs. The bill also expands eligibility to include community sewerage systems and exempts certain technology purchases from standard state procurement rules.

MODERATE
The bill was amended to add new funding priority tiers for septic system upgrades, specifically targeting Maryland Chesapeake Bay 8-digit watersheds with high nitrogen reduction effectiveness and properties within 500-year floodplains. The bill also corrected a clerical error in the repeal language and updated the bill status to reflect Senate adoption.
Scope change
The bill's scope was expanded to include additional priority categories for funding eligibility beyond the original Chesapeake and Atlantic Coastal Bays Critical Area designation.
ELIGIBILITY

Added new priority tier for failing septic systems located in Maryland Chesapeake Bay 8-digit watersheds with a relative effectiveness for total nitrogen reduction of 9.24 or higher based on the Chesapeake Bay Watershed Model.

Added new priority tier for failing septic systems located within the 500-year floodplain.

Reordered priority tiers to place the new watershed and floodplain categories before the general public health and water quality threat category.

TECHNICAL

Corrected clerical error in repeal language from 'with amendments' to 'without amendments' in the second repeal section.

Reorganized the bill structure to reflect Senate adoption and committee report status.
