For these facilities, compliance with emission limits is demonstrated by continuous and/or annual compliance emission monitoring. The specified test procedure for particulate is ISO 9096.

Clause 4.4.7 of EN 303-5 does not require continuous monitoring or lay down frequency of particulate measurements or specify the test method (ISO 9096) and therefore compliance with UK legislation cannot be guaranteed for those boilers which fall within the scope of PG1/12.

C.8 Deviations for Italy

Sub-clause 4.4.6

Table 6 Emission limits

EN 303-5 differs from the Italian law: Decreto legislative n. 152 del 3 aprile 2006 "Norme in materia ambientale" (G.U. Serie generale n. 88 - 14/4/2006) (Legislative Decree n. 152 -3 April 2006 - “Regulation on environmental matter” - G.U. General n. 88 - 14/4/2006).

Therefore the following А-Deviation shall be taken into account.

Italian DLgs 152/2006, Annex IX, Part 3, Section 2 states as following:

Excerpt

Biomass heating plants shall respect the following emission limits, with regard to 1 hour running period under most required conditions:

Table C.12

Plant nominal thermal output (MW)

>0,035 T <0,15

>0,15 4-<1

350 mg/Nm3

Nitrogen Dioxide (expressed as NO2)


500 mg/Nm3

Sulphur Dioxide (expressed as SO2)


200 mg/Nm3

NOTE Emissions refer to an 11% O2 concentration.



Concerning biomass for energy purposes, the decree allows only the use of (excerpt):

  1. Vegetable material from forestry activity, forest maintenance and pruning (mainly compiles to class

  1. in EN 14961-1:2010);

  1. Vegetable material produced by exclusively mechanical processes on: untreated wood made by bark, sawdust, chips (omission) not contaminated by pollutants (mainly compiles to class 1.2.1 in

EN 14961-1:2010.

Moreover, Italian DLgs 152/2006, Annex IX, Part 3, Section 1 states the following limits:

(informative)

Relationship between this European Standard and the Essential
Requirements of EU Directive 2006/42/EC Machinery Directive

This European Standard has been prepared under a mandate to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential Requirements of the New Approach Directive 2006/42/EC Machinery Directive.

Once this standard is cited in the Official Journal of the European Union under that Directive and has been implemented as a national standard in at least one Member given State, compliance with the clauses referred to in this standard confers, within the limits of the scope of this standard, a presumption of conformity with the corresponding Essential Requirements of that Directive and associated EFTA regulations.

WARNING — Other requirements and other EU Directives may be applicable to the product(s) falling within the scope of this standard.
