Brazil’s National Mining Agency (ANM) said the deadline for written contributions to a proposed set of safety rules for mining waste piles was October 14, 2026, concluding a 45-day public-consultation period.

In a notice published on October 13 at 11:48 a.m. Brasília time, the regulator said the deadline would not be extended. The consultation, identified as Public Hearing No. 02/2026, concerns a draft resolution on safety management and emergency preparedness for mining piles.

The process does not establish new rules yet. ANM said it would analyze and consolidate the submissions, refine the proposal and then send it for deliberation.

What happened

The official participation platform lists the consultation as running from August 31 through October 14, 2026. It includes the draft ANM resolution, a regulatory-impact analysis and supporting materials.

ANM’s October 13 notice described October 14 as the final day for written contributions. The Brasil Participativo page independently identifies that date as the scheduled end of the process, although its live-status labels displayed inconsistent indications on October 14. Those labels do not establish the precise time at which submissions stopped being accepted.

The proposed regulation would introduce specific requirements for the safety management of mining piles and for emergency preparedness. The materials available through the consultation form the basis for public input before the agency completes its review.

Why it matters

Public consultations are a formal stage in the development of Brazilian regulation, allowing interested parties to comment on a draft and its underlying regulatory-impact analysis before a regulator considers whether to alter and advance the text.

For mining companies, workers, communities and other affected parties, the process concerns the standards that could eventually govern how mining piles are managed and how emergency preparedness is addressed. But the available ANM notice does not indicate that a final standard has been approved or entered into force.

The distinction is important: the October 14 deadline concerns contributions to a proposal, rather than compliance with an already-established new rule.

The bigger picture

The ANM has framed the consultation around two connected areas: safety management and emergency preparedness for mining piles. By publishing both a draft resolution and a regulatory-impact analysis, the agency has put the proposed approach and its supporting assessment into the public record for review.

The next stage is administrative rather than final. ANM said it would assess the comments received, consolidate them and refine the proposal before forwarding it for deliberation. The agency’s notice does not specify when that deliberation will occur or what final text, if any, will result.

By the numbers

What happens next

ANM is expected to analyze and consolidate the contributions submitted during the consultation, revise the proposal as it considers appropriate, and send the text for deliberation. Until that process is completed, the draft remains a proposed regulation rather than a final ANM rule.
