generation and the type of emission, and the characteristics of the air emission dischargedthrough chimneys and ducts. In addition to the above, with regard to emissionsregulated by official Mexican standards, the results of the tests and analysis donein accordance with such standards must also be reported. Such information must bereported for each contaminant.4.4. Regulation of the LGEEPA Regarding the Registration of Emissionsand Transfer of Contaminants296C H A P T E R X V I IAs we have mentioned, on June 3, 2004, the Regulation of the LGEEPA regarding Registrationof Emissions and Transfer of Contaminants (RETC) was published in the OfficialFederal Gazette, the purpose of which was to regulate the emissions and transfer of contaminants.The information from the database of the Registry will be composed of theinformation and documents contained in the authorizations, cards, reports, licenses,permits and concessions processed by SEMARNAT or the competent authority of the governmentof the Federal District, the states and municipalities. SEMARNAT will coordinatewith these other non-federal governmental authorities in order to harmonize the informationto be introduced into their respective databases.The RETC establishes that the fixed sources under federal jurisdiction, as well as generatorsof hazardous waste and those who discharge wastewater into national bodies ofwater, will be considered establishments subject to federal reporting (through their COA).In addition, the definitions article establishes the “substances subject to federal reporting”in the following form: chemical elements or composites that are emitted or transferredby the establishments subject to federal reporting. The elements that are emittedare determined based on their environmental persistence, bio-accumulation, toxicity,teratogenicity, mutagenicity or carcinogenicity and, in general, on their adverse effectson the environment.In relation to the technical guidelines of the Registry, the Regulation adds that the substancessubject to federal reporting, the reporting thresholds (minimum amount beyondwhich its emissions must be reported), and the technical and procedural criteria forincluding and excluding substances will be determined by the corresponding officialMexican standard (norma oficial mexicana, NOM), which will take into account substancesand contaminants of the air, water, soil, and subsoil, hazardous materials and wastes, aswell as persistent organic compounds, greenhouse gases, and substances affecting theozone layer. As of this date this official Mexican standard has not yet been issued.Similarly, the RETC clarifies that the emissions and transfer of contaminants and substancessubject to federal reporting that are regulated by official Mexican standardsmust be measured using the methods, equipment, and testing and reporting proceduresspecified by the NOMs and by the Federal Law of Metrology and Standardization
