Bill Summary · SB 168

Legislative bill overview

SB 168 would have imposed a moratorium on the construction of new Confined Aquatic Disposal (CAD) cells in Maryland, preventing the state from creating new underwater sites for depositing dredged material. The bill passed through the legislature but was vetoed by the Governor in May 2025, effectively blocking its implementation.

Why is this important

CAD cells are used to manage dredged sediment from navigation channels and waterways, which is a necessary part of maintaining ports, harbors, and waterway infrastructure. The moratorium would have significantly constrained Maryland's ability to conduct dredging operations and maintain commercial shipping channels, potentially affecting port operations and economic activity. The Governor's veto suggests concerns about balancing environmental protections with practical infrastructure needs.

Potential points of contention

  • Environmental protection vs. infrastructure maintenance: Environmental groups may support the moratorium to protect aquatic ecosystems, while shipping and port industries oppose restrictions on dredged material disposal options
  • Cost implications: Restricting CAD cell construction could increase costs for dredging operations by forcing use of alternative, potentially more expensive disposal methods
  • Regulatory clarity: Businesses need certainty about where and how dredged material can be disposed; a moratorium creates regulatory uncertainty unless alternative disposal sites are guaranteed
