From 1 October, dredgers moving more than 1 million cubic yards a year in Alabama's coastal area must put at least 70% of the material to a beneficial use. The requirement applies only to the extent that federal funding has been allocated and permitted in-state sites have capacity for suitable material.

The enacted 70% rule still needs implementation evidence

Alabama's enrolled HB181 sets the 1 October 2026 effective date, the one-million-cubic-yard threshold, the 70% requirement and the funding, site-capacity and emergency exceptions. It also excludes ordinary deposition into public waters from the state definition unless the work is shoreline restoration or marsh creation. Mobile District's current programme page lists the four available federal-standard routes, while its 20 July commentary gives the approximate annual volume and explains that no single route suits all material. The official source set was rechecked on 10 August; it does not establish final ADEM or ADCNR rules, package-level federal allocation, approved-site capacity or accepted contract quantities.

Mobile Harbor still needs more than one placement route

Mobile Harbor produces about 6 million cubic yards in a typical year, including roughly 4 million from the Bay Channel. That is far above the statutory threshold, but the harbour handles different sediments through upland sites, thin-layer placement, Sand Island and the ocean site. Each contract still needs a workable destination, transport method and permit basis.

Evidence conclusion

Three checks come before the percentage

The law changes the evidence needed for route selection; it does not make every placement method interchangeable. Before treating 70% as a contract quantity, confirm allocated federal funding, a permitted Alabama site with available capacity and material that the site can accept. The state definition is also narrower than the federal one: depositing material in public waters counts only when it forms part of shoreline restoration or marsh creation. A 10 August review of the official source set found the enacted duty and agency implementation mandate, but no final ADEM or ADCNR rule text or package-level funding allocation; those records remain unpublished.

Outstanding evidence

  • Published ADEM and ADCNR implementation rules before the 1 October effective date
  • Federal beneficial-use funding allocated to each qualifying dredging programme
  • Permitted Alabama sites, remaining capacity and accepted sediment classes
  • Contract quantities routed to shoreline restoration, marsh creation, upland placement, Sand Island and ocean disposal
  • DQM records, placement surveys and owner acceptance by destination
