HB 1296 Maryland House of Delegates · 2025 Regular Session

Environment - Managed Aquifer Recharge Pilot Program - Establishment

HB 1296 establishes a pilot program to test using treated wastewater for groundwater recharge in Maryland. The bill authorizes the Department of the Environment to review and permit demonstration facilities that treat reclaimed water to strict quality standards (including PFAS limits and pathogen reduction) for testing groundwater augmentation. It directly affects water treatment facilities and localities facing anticipated groundwater issues like saltwater intrusion or land subsidence within the next 25 years. The program requires facilities to prove they address specific groundwater problems, meet federal and state water quality standards, and undergo testing before permits are issued. This is strictly a testing phase for feasibility, not permanent implementation.

MODERATE

The bill was advanced from first to third reading with amendments that expanded the scope of sections repealed and added new definitions for groundwater augmentation. The bill now prohibits groundwater augmentation except under specific circumstances established by the new pilot program, and adds more environmental code sections to be repealed and reenacted.

Scope change

The bill's scope expanded from establishing a pilot program to also prohibiting groundwater augmentation outside the pilot program framework, and the list of repealed code sections was significantly expanded to include additional environmental protection statutes.

SCOPE

Added language prohibiting groundwater augmentation except under the pilot program circumstances, making the pilot program the exclusive pathway for this activity.

REQUIREMENT

Expanded the list of Maryland code sections being repealed and reenacted from 9 sections to 17 sections, including new sections 7-201 and 9-101 related to hazardous substances and sewerage systems.

DEFINITION

Added new definitions for 'Federal act', 'Hazardous substance', 'Discharge', 'Industrial user', 'Pollutant', 'Sewerage system', 'Aquifer', 'Confined aquifer', and 'Demonstration facility' to clarify regulatory requirements.

ELIGIBILITY

Modified the list of permit types in Section 1-601 to add managed aquifer recharge pilot permits as a distinct category, requiring separate permitting under the new program.

TECHNICAL

Added explanatory notes about formatting conventions (capital letters, brackets, underlining, strikeouts) to help readers understand amendments to existing law.
