Methylamine: BREF LVOC summary of system established in CEPSA Química: BAT. PHENOL/ACETONE: Process via cumene oxidation formed by alkylation: BAT

Pagina 1 de 3 CEPSA Química Control of Air Pollution Emissions QUIMICA IPPC DEVELOPMENT: requirements Fuel: Priority utilization of natural gas. Minimization of Fuel-oil (Voluntary objective) High reduction in SOx and Nox emissios 2004: Only one furnace used FO and NG simultaneously: B-401. New plant that started at 2007: furnace designed only for natural gas. 2008: stopped use of FO. 2009: New furnace B-401N to substitute old B-401. New furnaces: Low NOx burners. B-401 NOx emissions below limits.

Pagina 1 de 3 CEPSA Química QUIMICA IPPC DEVELOPMENT: requirements Control of Air Pollution Emissions Continuous emissions Monitoring system for furnaces > 50 Mw: (B-401/ B-401N) and cogeneration plant. Adaptation of platform and ladder in furnace B-401’s stack for air emission measurements. Design of stacks to optimize dispersion of pollutant.

Pagina 1 de 3 CEPSA Química QUIMICA IPPC DEVELOPMENT: requirements Control of Air Pollution Emissions Minimization of Volatile Organic Compound emissions (VOC’s) (Voluntary objective) Optimization of activated charcoal chambers system to reduce VOC in air from oxidation reactors. New vents absorber of Methylamine plant. Reduction of atmospheric vents from trucks and drums loading. Change of open samplings systems to closed-loops. Pump Seals: Substitution of water systems to gas closed circuits. Establishment of a Leak Detection and repair (LDAR) program.

Pagina 1 de 3 CEPSA Química QUIMICA CEPSA Química has a Cogeneration plant that has an independent IPPC Permit. Reduction of limit to NOx: 500 to 75 mg/Nm3. Change to a gas generator with Dry Low Emissions technology. 8 MM €. Investment 8 MM €. IPPC DEVELOPMENT: requirements Control of Air Pollution Emissions

Pagina 1 de 3 CEPSA Química Control of Waste Water Emissions QUIMICA IPPC DEVELOPMENT: requirements Process water waste is sent to a primary treatment and then goes to the treatment plant where the contaminants are eliminated through a biological cleaning process: Emission point #1 IPPC permit established authorized waste water limits and how they must be controlled. CQ have made Investments to optimize effluent plant in order to improve the quality of the waste water even better than limits: Design and implementation of new system of waste water treatment from new plant that started operation at Optimization of control elements to lower contamination of waste water. New filter system for sludge excess

Pagina 1 de 3 CEPSA Química Control of Waste Water Emissions QUIMICA IPPC DEVELOPMENT: requirements The rainfall water has an independent circuit: Emission point #2 IPPC permit established that water could only be sent at this emission point when it's raining and must be free of contaminants. CEPSA Química had made Investments to take residual water out of rainfall circuit. Implementation of Continuous Flow equipment that allows us to control that rainfall circuit only operates when it’s raining.

Pagina 1 de 3 CEPSA Química Control of Wastes QUIMICA IPPC DEVELOPMENT: requirements IPPC permit established authorized Hazardous waste and regulations about its management. CQ has established techniques and operational controls to minimize wastes. New temporary warehouses has been built to gather the residues. Selective gathering of residues has been improved.

Pagina 1 de 3 CEPSA Química Control of soil and groundwater QUIMICA IPPC DEVELOPMENT: requirements CQ has established techniques and operational controls to avoid this contamination. Special attention to storage: leak proofing of storage tanks, built over pedestal with leaks detectors, bunds,….. Protection of land of Operational areas by use of waterproof concrete.

Pagina 1 de 3 CEPSA Química Other requirements stipulated in the permit QUIMICA IPPC DEVELOPMENT: requirements Internal and external measurements, control and report of air emissions, waste water, wastes…(many of these are indicated on environmental legislation). Audits of compliance of requirements from IPPC permit by administration (each 2 years, measurements including). Establish obligation of Communication: environmental incidents/accidents, changes in process, productive stops…. Realization of annual report of “European Regulation on Pollutant Release and Transfer Registers (E-PRTR)”.
