The initiative to enact a new General Law of Ecological Balance and Environmental Protection (LGEEPA), introduced by the Federal Executive in September 2026, proposes changes that could affect the planning and operation of mining projects. The text is still undergoing the legislative process and may be amended before approval. For the time being, the obligations described below are proposals and are not currently in force.

One of the key areas of interest for the sector is mine closure. The initiative would retain the obligation to have a restoration, closure and post-closure program in place, while allowing SEMARNAT to require updates when there are changes to the works, project conditions, environmental regulations, or the geotechnical and hydrogeological risks associated with mining waste deposits. For an operating mine, this could require a review of the estimated closure costs and the financial guarantee supporting them.

Federal Court Grants Plaintiffs’ Motion For A Preliminary Injunction In Challenge To New Mexico’s PFAS Labeling Requirement

A federal court in New Mexico has granted a preliminary injunction against the state's PFAS labeling rule for consumer products, finding that the regulation likely violates constitutional protections for commercial speech. The court questioned whether the state's characterization of the label as a "consumer awareness" measure rather than a warning undermines the connection between New Mexico's stated health and environmental interests and the means used to achieve them.
