    Trump deep-sea mining permitting overhaul: legal and design notes for engineers

    Trump deep-sea mining permitting overhaul: legal and design notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Trump’s National Oceanic and Atmospheric Administration has overhauled Deep Seabed Hard Mineral Resources Act regulations to merge the two-step exploration licence and commercial recovery permit into a single, shorter review, potentially halving permitting times for polymetallic nodule projects in US and international waters. The Metals Company has already applied under the Trump-era framework for exploration over 199,895 sq. km and a 25,160 sq. km commercial recovery area in the Clarion-Clipperton Zone, while Impossible Metals is pursuing AI-guided AUV nodule collection off American Samoa and in Bahraini waters. The move raises legal and environmental uncertainty because the US has not ratified the UN Convention on the Law of the Sea or the International Seabed Authority regime governing mining beyond national jurisdiction.

    Technical Brief

    • NOAA’s revised DSHMRA rules allow applicants to choose either the legacy two-step or new consolidated pathway.
    • The regulatory change was first tabled in July 2025, following a Trump executive order targeting deep-sea mining growth.
    • NOAA states the consolidation “modernises the law” and explicitly links it to an “America First” critical minerals agenda.

    Our Take

    Among the 90 Policy stories in our database, deep-sea extraction in the Clarion-Clipperton Zone is still a niche compared with onshore critical minerals projects, so any US move to clarify permitting for polymetallic nodules could quickly reposition it from a fringe to a mainstream supply option for cobalt, nickel and manganese.

    The estimated 1 billion metric tons of polymetallic nodules in US waters, if even partially commercialised, would give Washington a domestic lever over battery metals that currently feature in many of our ‘critical minerals’ pieces as being dominated by supply chains routed through China and the Guangzhou Futures Exchange.

    Because the Clarion-Clipperton Zone spans multiple Pacific jurisdictions including US-linked areas such as Hawaii and American Samoa, streamlined US permitting would likely increase the strategic importance of negotiations with the International Seabed Authority relative to the more conventional land-based projects that dominate our sustainability-tagged coverage.

    Government policies to drive mining investment in 2026: key takeaways for project teams

    Government policy is set to dominate mining investment in 2026, with 47% of respondents to White & Case’s Mining & Metals 2026 survey citing political variables and nearly 40% expecting state‑backed financing to be the main tool in developed markets. Some 73% foresee widening divergence between US and Chinese critical minerals policy, while a funding gap between the US and Europe is seen as a key opportunity, alongside risks of over‑expansion and a two‑to‑three‑year “gold rush” bubble. Copper and gold are viewed as the “sure bet” price risers, with gold miners seen as prime consolidation targets and strategic partnerships favoured over traditional M&A.

    Sustainability and transparent reporting in construction: key shifts for engineers

    Sustainability reporting in construction is described as fragmented and inconsistent, with project disclosures difficult to compare and data quality varying widely across contractors and asset owners. This patchwork approach is exposing schemes to reputational, regulatory and operational risk, particularly as clients demand verifiable carbon footprints, lifecycle assessments and supply chain traceability aligned with frameworks such as the GHG Protocol and EU taxonomy. For geotechnical and civil engineers, the direction of travel points to standardised metrics on embodied carbon in concrete and steel, site energy use and materials sourcing becoming routine contract requirements.

    Phil Layton as CECE president: decarbonisation and EU machinery rules for engineers

    JCB technical service director Phil Layton has begun a two-year term as president of the Committee for European Construction Equipment (CECE), representing the UK’s Construction Equipment Association. Layton plans to prioritise decarbonisation of construction machinery fleets, support for open global markets and a more competitive regulatory framework for European OEMs. CECE’s immediate policy push targets EU secondary legislation on road circulation of construction machinery and a guidance document for implementing the new Machinery Regulation, ahead of the CECE congress in London on 27–29 October.
