Yesterday, a Mexican citizen filed a submission, under Chapter 24 of the United States-Mexico-Canada trade agreement (USMCA/CUSMA) with the Commission for Environmental Cooperation (CEC), asserting that Mexico is failing to effectively enforce its environmental laws to regulate air emissions from the Ing. Héctor R. Lara Sosa Pemex refinery (known as the Cadereyta Refinery) in Nuevo León, Mexico and to manage the resulting air pollution in the Monterrey metropolitan area.

In submission SEM-24-002 (Cadereyta Refinery), the Submitter asserts that Mexico is failing to address the air pollution issues caused by the operation of the Cadereyta oil refinery, owned and operated by Pemex. The Submitter alleges that Mexico is failing to effectively enforce environmental laws to manage air emissions and the resulting air pollution from the facility affects the Monterrey metropolitan area which has a population of 7 million people. The Submitter asserts that air pollution from the refinery has become worse over the last 5 years despite appeals from residents and the state of Nuevo León to the federal authorities to take action to improve air quality.

The Submitter cites provisions from the Mexican Constitution, the General Act on Ecological Balance and Environmental Protection (Ley General del Equilibrio Ecológico y la Protección al Ambiente), Law of the National Agency of Industrial Safety and Protection of the Environment in the Hydrocarbons Sector (Ley de la Agencia Nacional de Seguridad Industrial y de Protección al Medio Ambiente del Sector Hidrocarburos), Environmental Responsibility Act (Ley de Responsabilidad Ambiental) and other regulatory instruments.

The Secretariat will review the submission and determine, within 30 days, whether it meets the requirements of USMCA/CUSMA Articles 24.27(1), (2) and (3). To learn more, please consult the registry page for the submission SEM-24-002 (Cadereyta Refinery).
