  1. REPORT ON DIOXINS AND FURANS IN THE MEXICAN POLLUTANT RELEASE AND TRANSFER REGISTER PRTR/RETC Octubre, 2010

  2. CONTENTS • Background and legal framework • Calculation methodology on COA license • Dioxin and furan reporting in the RETC • Opportunities and conclusions

  3. Water releases Waste transfers Air releases Transfers to sewers Soil releases What is the Mexican PRTR/RETC? The Pollutant Release and Transfer Register (Registro de Emisiones y Transferencia de Contaminantes—RETC) is an environmental policy instrument designed to collect, integrate and release public information on potentially harmful pollutants from a wide range of sources. National public database of releases and transfers of 104 substances

  4. Amendment to Art. 109 BIS COA form RETC Regulation Reportable Substances Ruling Release Inventory Ruling Marco Legal PRTR/RETC Legal Framework • December 2001 amendment to Art. 109 Bis of the Environmental Act (LGEEPA) • Federal, State and Municipal PRTR • Transparency & Access to Information Act, June 2002 (federal) • RETC Regulations, June 2004 (federal) • Rulings, 2005 • Electronic COA License Form, January 2005 • List of 104 RETC-reportable substances

  5. Environmental Regulations Monitoring and Information Collection Instruments Public Information Instruments Direct Regulation Instrument Sole Environmental License (LAU) Annual Operating Certificate (COA) Pollutant Release and Transfer Register (RETC) Instrument for the reporting and collection of information on pollutant releases and transfers into the air, water, soil and subsoil, and hazardous waste and materials National public database recording releases (air, bodies of water and soil) and hazardous waste transfers and treatment systems for 104 substances Authorization for industrial establishments under federal jurisdiction (11 sectors) on air pollution prevention and control

  6. CFC HCFCs HBFC TET Halons BrM 12 Persistent Organic Pollutants (POPs) 17 Montreal Protocol 6 Greenhouse Gases Climate Change • Substances selected for persistence, • Bioaccumulation and toxicity based on: • NOMs (air, water & waste) • List of high-risk activities • Toxic substances catalog (Health Ministry) • CICOPLAFEST pesticides list 104 reportable substances

  7. Integration of National and Trinational PRTR • Federal: • 11 activities under federal air pollution jurisdiction • Major hazardous waste generators • Discharges into national bodies of water • Published in 2004, 2005, 2006 & 2007 TRINATIONAL PRTR NATIONAL PRTR/RETC • State: • Activities under state jurisdiction • Special-landing waste generators • 20 states have legal framework and use state COA software • States that have published: NL (2006), Mexico City, Durango & Michoacán • (2006 & 2007), Guanajuato (2008) • Municipal: • Commerce and services • Sewer discharges • Municipal solid waste • Tijuana in process of • implementing

  8. Dioxins & Polychlorinated Furans (D&F): In solid+liquid+gaseous phases Four documented factors in formation: Trace levels of D&F in unburned waste carried to release point Formation enhanced by presence of precursors consisting of similarly structured chloride compounds (in high-temperature combustion chambers or at sites with lower temperatures) D&F synthesized from different organic compounds and a chlorine donor. Reactions catalyzed involving particles at low temperatures (250–600°C). Higher temperatures necessary to destroy them (above 850°C).

  9. Dioxins & Polychlorinated Furans (D&F) (continued) Structures Dioxins (75 congeners or members of the same chemical family, from mono- to octachlorides) Furans (135 congeners, from mono- to octachlorides)

  10. * limit for new incineration facilities ** limit for facilities existing before NOM published (1 October 2004) *** applicable limit when gas temperature to control system does not exceed 400°F I-TEQDF stated as toxic equivalent with respect to 2,3,7,8- tetrachloro-dibenzo-p-dioxin replacement All limits converted to 298ºK and 7% O2

  11. * applicable limit in Mexico City Metropolitan Area, Critical Zones and Rest of Country ** applicable limit when gas temperature to control system does not exceed 400°F I-TEQDF stated as toxic equivalent with respect to 2,3,7,8- tetrachloro-dibenzo-p-dioxin replacement All limits converted to 298ºK and 7% O2

  12. Co-Benefit TSP + PCDD & PCDF Abatement UNCONTROLLED PARTICLES PARTICLES Dioxins & Furans CONTROL EQUIPMENT STANDARD COMPLIANCE BEST OPERATING PRACTICES I Particles Intentional & unintentional POPs Reduction, control & elimination Source emissions

  13. Dioxins and furans tend to stick to particles and use them to travel long distances. • The same thing happens with heavy metals and mercury. • Efficient control of dry or wet particles controls dioxins and furans accordingly.  

  14. CONTENTS • Background and legal framework • Calculation methodology on COA license • Dioxin and furan reporting in RETC • Opportunities and conclusions

  15. Annual Operating Certificate • Flowchart • Raw materials • Fuel & energy consumption • Air pollutant releases • Equipment & activities generating emissions • Water consumption & discharges • Type of pollutants in discharges • Generation of hazardous waste • Handling by service companies • Handling plans • Treatment of contaminated soils • Use, production and disposal of reportable substances • Releases & transfers of 104 reportable substances • Pollution prevention actions I General technical information II Air pollutant releases Registration Data III Water releases & transfers • Establishment name • Environmental or operating license (LAU/LF) • Address, phone, email • Geographical coordinates • Personnel & operating hours IV Waste generation, management & transfer V Releases & transfers of reportable substances

  16. Cement Production

  17. NOM-098-SEMARNAT-2002 Regulated Pollutants Report NOM-040-SEMARNAT-2002

  18. RETC-Reportable Substances • Recurring problem: duplication of report in sections 2.3 & 5.2 • Table 2.3 reports combustion gases & regulated pollutants • Table 5.2 reports RETC substances, including dioxins and furans in any amount

  19. Key Sectors • Hazardous waste treatment - NOM-098-SEMARNAT-2002 • Cement & slaked lime - NOM-040-SEMARNAT-2002 • Oil & petrochemicals  (refinement)

  20. CONTENTS • Background and legal framework • Calculation methodology on COA license • Dioxin and furan reporting in RETC • Opportunities and conclusions

  25. CONTENTS • Background and legal framework • Calculation methodology on COA license • Dioxin and furan reporting in RETC • Opportunities and conclusions

  26. Opportunities and Conclusions • Strengthen, harmonize and link institutional databases containing information on PCDD, PCDF and their sources (such as PRTR-RETC, D&F inventory, Proname) in Semarnat • Share and release unified information • Enable access to information on best available techniques and best environmental practices to eliminate or reduce PCDD and PCDF releases

  27. Opportunities and Conclusions • UNEP BAT/BEP guidelines use particle controls as the primary measure of reduction at a number of sources. Update Mexico’s NOM-043-SEMARNAT-1993 • Provide information on the facilitation of technology transfer and enterprise capacity building • Release and make information available to interested parties • Assess co-benefits of reducing greenhouse gas emissions from the reduction of dioxins and furans

  28. Opportunities and Conclusions • Need for standardized quantification methodology to work on release factors • Double-counting (due to COA sections or corporate/plant reporting) • Amendments to COA form, migration to a new IT platform and break out a specific PCDD-PCDF section on COA • Continue work to publish a new official standard with a more complete list of reportable substances

  29. Opportunities and Conclusions • Automation of review of COA-RETC database information and optimization of information processing times, to increase the reliability and consistency of information • Continue working on actions to enhance the quality of information, such as workshops to offer industry feedback on guidelines • Continue building capacities to review and publish information in states (32) and municipalities (100) • Feedback and execution of the PRTR Information Awareness Master Plan • Improve the exchange of information among agencies and other international organizations • Continue sharing international experiences in the implementation and updating of the PRTR
