ANNEX

FRAMEWORK

The aims of the criteria

These criteria aim in particular at promoting:

— the reduction of impacts on habitats and associated resources,

— the reduction of energy consumption,

— the reduction of discharges of toxic or otherwise polluting substances into the environment,

— the reduction of use of dangerous substances,

— information that will enable the consumer to use the product in an efficient way which minimises the whole environmental impact.

The criteria are set at levels that promote the labelling of hard floor-coverings that are produced with low environmental impact.

Assessment and verification requirements

The specific assessment and verification requirements are indicated within each criterion.

The product group is structured in the following way (CEN definitions are reported in brackets) and can be subdivided into 2 major subgroups, ‘natural products’ and ‘processed products’ as follows.

Natural stones (CEN TC 246) are pieces of naturally occurring rock, and include marble, granite and other natural stones. ‘Other’ natural stones refers to natural stones whose technical characteristics are on the whole different from those of marble and granite as defined by CEN/TC 246/N.237 prEN 12670 ‘Natural stones — Terminology’. Generally, such stones do not readily take a mirror polish and are not always extracted by blocks: sandstone, quartzite, slate, tuff, schist.

The group of ‘processed stones’ can be divided into hardened and fired products. Hardened products are agglomerated stones, concrete paving units and terrazzo tiles. Fired products are ceramic tiles and clay tiles.

Agglomerated Stones are industrial products manufactured from a mixture of aggregates, mainly from natural stone grit, and a binder as defined by CEN/TC 246-229. The grit is normally composed of marble and granite quarry granulate and the binder is made from artificial components as unsaturated polyester resin or hydraulic cement. This group includes also artificial stones and compacted marble.

Concrete paving units are products for outer floor-coverings obtained by mixing sands, gravel, cement, inorganic pigments and additives, and vibro-compression as defined by CEN/TC 178. This group also includes concrete flags and concrete tiles.

Terrazzo tiles are a suitably compacted element of uniform shape and thickness, which meets specific geometrical requirements as defined by CEN/TC 229. The tiles are single or dual-layered. The single-layered are tiles completely made of granulates or chipping of a suitable aggregate, embedded in grey and white cement and water. The dual-layered tiles are terrazzo tiles made up of the first face or wear layer (with single-layered composition) and a second layer, known as backing or base concrete layer, whose surface is not exposed during normal use and which may be partially removed. Ceramic tiles are thin slabs from clays and/or other inorganic raw materials, such as feldspar and quartz as defined by CEN/TC 67. They are usually shaped by extruding or pressing at room temperature, dried and subsequently fired at temperatures sufficient to develop the required properties. Tiles can be glazed or unglazed, are non-combustible and generally unaffected by light.

Clay tiles are units which satisfy certain shape and dimensional requirements, used for the surface course of pavements and manufactured predominantly from clay or other materials, with or without additions as defined by CEN. The specific weight of such tiles shall not exceed 40 kg/m2.

Where so indicated, certain criteria apply specifically to one of the above subgroups. If no particular mention is given, the criterion applies to all products. Details on calculation procedures are given in the Technical Appendix.

Where appropriate, test methods other than those indicated for each criterion may be used if their equivalence is accepted by the competent body assessing the application.

Where possible, testing should be performed by appropriately accredited laboratories or laboratories that meet the general requirements expressed in standard EN ISO 17025.

Where appropriate, competent bodies may require supporting documentation and may carry out independent verifications.

The competent bodies are recommended to take into account the implementation of recognised environmental management schemes, such as EMAS or ISO14001, when assessing applications and monitoring compliance with the criteria (note: it is not required to implement such management schemes).

CRITERIA

1. Raw materials extraction

1.1. Extraction management (for natural products only)

The overall extraction management score for natural stones shall be calculated as the total score based on a matrix of 9 main indicators (I). The final score results from the sum of the individual scores given to each indicator, after multiplication by a corrective weighting (W) if appropriate (see Technical Appendix — A1 for calculation procedures). Quarries shall reach a weighted score of at least 25 points. The score for each indicator shall be within the bounds indicated by the exclusion hurdle (where one is given).

In addition, all of the following conditions shall be met:

— there shall be no interference with any deep confined waterbed (see Technical Appendix — A1),

— there shall be no interference with surface water-bodies with civil catching or springs, or if the water-body is included in the Register of Protected Areas established by a Member State according to Directive 2000/60/EC of the European Parliament and the Council of 23 October 2000 establishing a framework for Community action in the field of water policy ( 2 ) or if the watercourse's average flow is >5 m3/s (see Technical Appendix — A1),

— there shall be a waste water recovery closed system for avoiding sawing waste dispersion to the environment and to feed the recycling loop. Water shall be contained in close proximity to the place where it is used in quarrying operations and then it shall be conveyed by closed pipes to the suitable processing plant. After clearing, water shall be recycled.

Assessment and verification: the applicant shall provide the calculation of the weighted overall extraction management score, and related data for each of the nine indicators (showing amongst others that each score is within the bounds of the corresponding exclusion hurdle, if one is given), according to the following matrix and to the corresponding instructions in the Technical Appendix — A1. The applicant shall also provide appropriate documentation and/or declarations that prove compliance with all of the abovementioned criteria.

TECHNICAL APPENDIX

The applicant shall provide all the required information calculated, measured or tested for the period immediately before the application. Measurements shall be representative for the respective series of testing and it should be consistent for all parts of the application as appropriate.

A1. Raw material extraction — indicators and weights definitions

Confined waterbed

The expression ‘confined waterbed’ identifies an artesian waterbed.

Average flow of the surface water-bodies

The average flow of the watercourse that interferes with the quarry shall be calculated taking into account the authorised area of the considered quarry. The calculation shall be made multiplying the section of the water body by the velocity of the water. The values shall be representative of at least 12 months.

Indicator description

I.1. Water recycling ratio

See A3.

I.2. Rehabilitation simultaneity degree

The calculation of I.2 consists of the measurement of the compromised area, which includes quarry front and active dump areas, and of the authorised area. These areas should be measured during operating activities.

I.3. Blocks recovery

The calculation of I.3 consists of the evaluation of commercial blocks and of the total volume yearly excavated. Commercial blocks (according to the rough block definition in CEN/TC 246/N.237 prEN 12670 ‘Natural stones — Terminology’) refers to the basis of utilisable stone consisting of rock from quarries suitable for further processing in order to obtain slabs or other architectural items.

I.4. Natural resource appreciation

The calculation of I.4 consists of the evaluation of the usable material and of the total volume extracted yearly. Usable material refers to all the volume which is not destined for dumps: for example commercial blocks, aggregate materials and everything else suitable for further processing and use.

I.5. Working conditions of operating equipment

The calculation of I.5 consists of the evaluation of the total number of hours worked by a machine for productive activities and its division by the yearly production (m3) of usable material. Usable material refers to all the volume which is not destined to dumps: for example commercial blocks, aggregate materials and everything else suitable for further appreciation. If more than one excavator or wheel loader is present in the quarry, the highest number of worked hours shall be taken into consideration.

I.6. Air quality

This indicator is described in Council Directive 1999/30/EC of 22 April 1999 relating to limit values for sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter and lead in ambient air ( 10 ). The calculation of I.6 consists of the measurement, along the border of quarry area, of PM 10 suspended particles based on the specific requirements of the test method and the general provisions of the Council Directive (PM 10 are defined in Article 2(11)). The test method is defined in EN 12341.

I.7. Water quality

This indicator considers the total emissions of suspended solids after treatment on surface water flowing out of the quarry site. The calculation of I.7 consists of the measurement of total suspended solids using the test method reported in ISO 5667-17.

I.8. Noise

This indicator considers the noise level recorded along the border of the quarry area. Non impulsive noises are to be measured. The calculation of I.8 consists in the measurement of the noise using the test method reported in ISO 1996-1.

I.9. Visual impact

The calculation of visual impact lies in tracing cross sections passing through the quarry front and other external ‘visual points’, which are important to determine the visual impact (for example either from nearby towns or from frequented places or major roads, etc.). The calculation of the final score, measured as a percentage, shall be taken from the highest value of originally calculated values (worst case situation). A short explanation for the finally chosen ‘visual point’ should be submitted to the Competent Body. From each visual point (P), the ‘bottom radius’ is traced, tangent to the topographic surface and intercepting the lowest point of the ‘visible quarry area’. The visible quarry area is regarded as the area where the excavation is carried out or where there is an active dump. Already rehabilitated areas (both in front area and dumps) need not be considered. From the same visual point a second radius (called ‘top radius’) is traced, intercepting the highest point of the quarry front. The top radius and bottom radius allow the identification on the section of the quarry of the limits of the height of the visible front (the vertical distance from top to bottom radius matching the front). The calculation could be made on the basis of the quarry project. These geometric data are put into the following formula and the result is the quotient of visual impact of the quarry affecting a specific visual point.

where (Figure A1):

h = vertical height of front visible from P visual point (in meters);

L = horizontal distance between the worst P and the front (in meters);

tan 30° = tangent of the average angle of the human eye vision cone;

x % = percent of visual impact.

The term h2 represents the base surface of the quarry visibility cone, while the term (L tan 30°)2 represents the base surface of the average visual cone of human eye.

Figure A1: Graphical definition of the visual impact indicator

The calculation of the score shall consider the highest value among the calculated values.

Weight description

W2. Soil protection/land capability classification

According to the European Soil Bureau's indication, land is graded on the basis of its potentialities and the severity of its limitations for crop growth into eight capability classes. An indicative description of the classes is as follows:

— Class I soils have slight limitations that restrict their use,

— Class II soils have moderate limitations that reduce the choice of plants or require moderate conservation practices,

— Class III soils have severe limitations that reduce the choice of plants or require special conservation practices, or both,

— Class IV soils have very severe limitations that restrict the choice of plants or require very careful management, or both,

— Class V soils have little or no hazard of erosion but have other limitations, impractical to remove, that limit their use mainly to pasture, range, forestland, or wildlife food and cover,

— Class VI soils have severe limitations that make them generally unsuited to cultivation and that limit their use mainly to pasture, range, forestland, or wildlife food and cover,

— Class VII soils have very severe limitations that make them unsuited to cultivation and that restrict their use mainly to grazing, forestland, or wildlife,

— Class VIII soils and miscellaneous areas have limitations that preclude their use for commercial plant production and limit their use to recreation, wildlife, or water supply or for aesthetic purposes.

A2. Raw materials selection

A closed-loop recycled material is defined as a material that is extracted from the production system and is returned to the same production system, eventually after a recycling treatment.

A3. Water recycling ratio

The calculation of the water recycling ratio shall be consistent with the following formula based on the flows highlighted in Figure A2.

Figure A2: Water flow scheme that shall be used to calculate Water Recycling Ratio ( 11 )

A4. Energy consumption calculation (PER, ERF)

When providing a calculation of process energy requirement (PER) or energy requirement for firing (ERF), the correct energy carriers shall be taken into account for the entire plant or for the firing stage only. Gross calorific values (high heat value) of fuels shall be used to convert energy units to MJ (Table A1). In case of use of other fuels, the calorific value used for the calculation shall be mentioned. Electricity means net imported electricity coming from the grid and internal generation of electricity measured as electric power.

Evaluation of PER for agglomerated stone production shall consider all energy flows entering the production plant both as fuels and electricity.

Evaluation of PER for terrazzo tiles production must consider all energy flows entering the production plant both as fuels and electricity.

Evaluation of ERF for ceramic tile production shall consider all energy flows entering all the kilns as fuels for the firing stage.

Evaluation of ERF for clay tile production shall consider all energy flows entering all the kilns as fuels for the firing stage.

Evaluation of PER for cement production shall consider all energy flows entering the production system both as fuels and electricity.

A5. Emissions to air (for processed products only)

The air pollutant emission factors shall be calculated as follow:

1. the concentration in the exhaust gas emitted to the environment of each parameter considered in the tables shall be calculated;

2. the measurements used for the calculation must be made following the testing methods indicated in the tables;

3. the samplings shall be representative of the considered production.
