The Official Gazette of the Constitutional Government of the Free and Sovereign State of Nuevo Leon, on April 2, 2024, published the Secretary of Health of Nuevo Leon’s "Agreement declaring an Atmospheric Pollution Alert" in Nuevo Leon, Mexico.

Contents of the Agreement

The agreement mentions various repercussions of climate change, especially in Nuevo Leon, which have been characterized by higher temperatures and reduced rainfall. These changes also have had an impact on the population by aggravating circulatory and respiratory diseases, as well as increasing the risk of cardiovascular diseases, strokes and various cancers, among others.

Therefore, an air pollution alert has been declared in the metropolitan area of Nuevo Leon. It seeks to establish urgent measures to safeguard the air quality of the state, urging different sectors to comply with the following actions:

 

Industrial Establishment

Systems and Equipment:

  • Maintain anti-pollution systems operating optimally
  • Install equipment and systems with the most advanced technology worldwide to control pollutant emissions into the atmosphere, so that they do not exceed the maximum permissible levels, according to the Environmental Law of the State of Nuevo Leon (Ley Ambiental del Estado de Nuevo León or Environmental Law)

Good Practices:

  • Minimize the generation of particulate matter in all activities
  • Dampen and clean areas of yards and internal and external roads adjacent to facilities
  • Do not have uncovered or non-humidified bulk particulate material storage areas
  • Do not use blowers to clean yards and internal and external roads adjacent to facilities
  • Dampen and keep clean all construction sites
  • Dampen before sweeping or cleaning yards and roads inside and outside facilities to avoid dust resuspension

  • Industry must comply with the maximum permissible limits established in the Mexican Official Standards (Normas Oficiales Mexicanas or NOMs) or State Standards (Normas Estatales)
  • Companies extracting and exploiting stone material (quarries) must maintain strict controls and avoid particle emissions in all their operations
  • Vehicles transporting particulate material must have a humidified material, an airtight box and a tarp or cover that completely covers the upper part, so that no material spills occur
  • Vehicles transporting concrete must not have any material spillage

Municipalities

Development Plans:

Application Activities:

  • Divert vehicles in areas of high vehicular contingency and road works
  • Remove ostensibly polluting vehicles from circulation

Verification:

  • Ensure that units transporting materials on public roads are in good physical and mechanical condition

Relevant Considerations

Days of No Circulation: The executive of the state instructs the secretary of environment of the State of Nuevo Leon, so that in coordination with the applicable agencies, they may restrict and subject to night hours the vehicular traffic and the respective maneuvers on public roads of cargo vehicles to expedite vehicular circulation and reduce polluting emissions.

Infractions and Security Measures: The agreement instructs the State Environmental Attorney's Office (Procuraduría Estatal de Protección al Medio Ambiente or PROFEPA) to impose the corresponding measures in case of verifying fixed or mobile sources of contamination.

Entry into Force: The agreement entered into force on April 2, 2024.
