Beginning March 2023, all businesses operating in Mexico regardless of size will need to comply with new requirements for wastewater discharge into rivers, basins, watercourses, other bodies of water, and into any type of surface.

Mandatory standard NOM 001 SEMARNAT 2021 (NOM 001 of 2021 or Wastewater Standard) that deals with permissible pollutant limits in wastewater discharged into surface and groundwater bodies goes into effect on March 11, 2023 (See March 11, 2022 Federal Official Gazette).

NOM 001 of 2021 replaces NOM 001 of 1996 that routinely allowed for underreporting of pollutants in wastewater according to government sources. NOM 001 of 2021 is more stringent and includes other contamination standards such as "true water color" and "water toxicity."

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.
