(I.P.P.C.);10 installations not compliant with Annex IIA
limits (waste gas and/or fugitive emission)Some activities not included in Annex IIB (Surface

THREE EXAMPLES OF INSTALLATIONS NOT COMPLIANT WITH ANNEX IIA
• Metal Coating (drying process, waste gas V.O.C. concentration > 50 mg/Nm3)
• Paper Coating (drying process, waste gas V.O.C. concentration > 50 mg/Nm3)
• Adhesive Coating (fugitive emission > 20% solvent input)
TARGET EMISSION (ANNEX IIB) NOT EQUIVALENT TO TOTAL EMISSION (ANNEX IIA)

Calculation of Target Emission (Annex IIB) Using Year 2004 Data
Total Mass of Solids: 120 + 170 = 290 t/y
Annual reference emission: 1,5 x 290 = 435 t/y
Target Emission: 25/100 x 435 = 108 t/y

Total emission Limit value Target Emission
78 t/y 108 t/y
EX. 1 - METAL COATING
Remarks• According to historical data provided by the operator, the total
mass of solids input in spray coatings is not constant
• High uncertainty in determining nominal capacity difficulty in determining the reference point for reduction
(Annex IIB): “The following scheme shall operate for installation for which a constant solid content of product can be assumed and used to define the reference point for emission reduction”

Activity: Adhesive coating onto metallic items before rubber application (dampers for automotive engines)
•3.400.000 items/y (24 h/d x 330 d/y);
•organic solvents input 33 t/y;
•adhesive solid content 34% (10 t/y).

ENVIRONMENT DEPARTMENT
Remarks• Solvent free adhesive not available at the time of authorization;• The operator opted for:
enclosure of application boxes to decrease fugitive emission (2007);
replacement of old abatement equipment with a new regenerative thermal oxidizer
• Total Emission value comparable with Target Emission due to new V.O.C. abatement performance (waste gas N.M.V.O.C. concentration 20 g/Nm3 instead of 50 mg/Nm3).
EX. 2 - ADHESIVE COATING(Annex IIB): “the operator shall forward an emission reduction plan which includes in particular decreases in the average solvent content of the total input and/or increased efficiency in the use of solids to achieve a reduction of the total emissions from the installation to a given percentage of the annual reference emissions, termed the target emission”

ENVIRONMENT DEPARTMENT
• Entry into force of S.E.D. in Italian Legislation only one year before first reduction step (31st OCT 2005 = T.E. x 1.5): very hard to lay out reduction projects with such a short time scale
• Enterprises Association and Operators found it difficult to deal with such a scheme, in particular because: products solvent free where not commercially available at that
time (coatings for plastic surfaces, adhesives…); very difficult to evaluate nominal capacity for certain activities:
which is the starting reference point?
CONCLUSIONS - 1
Implementation of SED Directive, Stakeholder Workshop - Bruxelles, 18 june 2010 23
ENVIRONMENT DEPARTMENT
• Italian Legislation for air pollution at that time concerned only with ELV in waste gases and their analytical monitoring, not with management plans
• The ELV that Local Competent Authority used to set in permits were usually lower than those set in Annex IIA of S.E.D. many installation already complied with Annex IIA
