Presentación6

The continuous improvement of the environmental conduct of ATLL Concesionaria de la Generalitat de Cataluña S.A. is one of the main objectives in the development of our activity as it allows for offering better service and the sustainable management of resources such as water, energy and the raw materials used.

The priority on environmental matters has to be and is the minimisation of the negative impacts on the environment and to guide actions toward the optimising of power consumption, good waste management and the improvement in spillage prevention systems using the best available practices and technological innovation.

The ATLL principles on environmental matters are defined in the Policy of the Integrated Management System (Spanish acronym SIG) where we are committed to comply with the current legal requirements considered as an essential value for the safety, health of people and protection of the environment.

In this sense, one of the main principles that the EU has fostered is the application of the EMAS (The Community Management and Environmental Audit or Eco-Management System and Audit Scheme, in its English acronym). EMAS is a management tool for organisations (industries, service companies, public institutions, etc.) that has the aim of assessing, displaying and improving its environmental performance. EMAS presents itself as a symbol of modern environmental management, of transparency and or environmental participation. It is a system that is increasingly adopted by more organisations who on a voluntary basis want to assess and improve their environmental performance.

We present ATLL’s Environmental Statement relating to the year 2012 with which it publishes the relevant information relating to its environmental management for the knowledge of the general public and interested parties.

I hope this is of interest to you.

Compromís sostenible

Alfredo Gutierrez ZavalaManaging Director of ATLL.

Actividad8

The distribution network of ATLL Concesionaria currently draws water from the two rivers that give it its name: the Llobregat River and the Ter River.

The draw off of the Llobregat river water is done at the Treatment plant (ETAP) located in the municipality of Abrera. The water from the Ter River is collected in the Pasteral reservoir, downstream from the Sau and Susqueda reservoirs. From this collection point it reaches the Ter ETAP, located in the municipalities of Llinars del Vallés, Cardedeu and Roca del Vallés.

Once the water has been purified into drinking water it is stored in the main reservoirs of both plants to be distributed through the network to the delivery points that comprise the supply grid of ATLL Concesionaria.

The desalination plant of the Llobregat basin contributes up to 60 Hm3/year and once the water has been purified for drinking it is distributed to the Fontsanta reservoir in Sant Joan Despí.

The desalination plant of the Tordera basin contributes up to 20 Hm3/year of drinking water.

Good practicesSustainability

Sludge treatment plant

From the year 2007 to 2011, ATLL has been committed to an ambitious Sustainability Plan largely aimed at the implementation of renewable energies and improved resources management (E.S. 2010). At present this has been a prime example of environmental efficiency and coherence.

Environmental management is an opportunity to evolve and reinvent oneself. ATLL also implements good environmental practices which are defined as actions aimed at reducing the negative impact on the environment pursuant to our activities and installations.

In some cases these are simple practices, with low cost and that are easily applicable, only involving changes in the productive organisation and in the behavioural habits of the workforce.

Below there is a listing of the main actions undertaken by ATLL considered as good environmental practices and afterwards some of them are described in greater detail.

1. Recovery of processed water at the ETAPs

2. Assessment of the sludge residues generated in the purification process

3. Recycling of selectively collected waste.

4. Renewable energy production

5. Collection of domestic cooking oil by ATLL personnel

6. Green procurement

7. Own consumption of renewable energy

8. The use of electric vehicles in the ETAPs

At ATLL we undertake actions pertaining to our activity that minimise the environmental impact and help to improve the environment.

11

Valorisation of the sludge waste generated at the ETAPs

At ATLL we sustainably manage the sludge waste generated at the ETAPs as these can be fully recycled as feedstock raw material in the manufacturing of aggregates.

ATLL collects the domestic cooking oil that each worker may generate in his household. The aim is to transform a highly contaminant type of waste into renewable energy through the obtaining of biodiesel fuel.

The main advantages attained with this initiative are:

• To remove a highly polluting type of waste from the sewage system

• To facilitate reuse of the purified water• To decrease the probability of organisms har-

mful to health and bad odours• To facilitate the purification treatment of waste

waters• To transform waste into renewable energy

This initiative cannot be fulfilled without the implication and collaboration of the workers of the different centres where collection points have been implemen-ted.

Environmental improvement and sustainability are the basic cornerstones

of the corporate culture of ATLL Concesionaria, which we share with

other public and private organisations.

To properly implement environmental management in the overall activities

it is essential to take on a series of commitments, both by ATLL itself as

an organisation, as well as by all its members.

On June 7, 8, 11 and 12, 2012, the certifying entity LGAI Technological Center S.A. (Applus+) performed the independent audit of the Integrated Management System (SIG).

On environmental matters the performance of the audit involved the 1st follow up of the Management System in accordance with the ISO 14001:2004 standard and the 2nd follow up of (EC) Regulation No. 1221/2009 EMAS III.

Environmental requirementsTo facilitate the identification and assessment of the legal requirements applicable to ATLL, an outside legal requirements update system is available (DL Plus) and another for technical regulations (NTalerta). On a monthly basis through these services, ATLL receives newsletters on the matters relating to the activities of the organisation. Using this service, on a monthly basis ATLL identifies the environmental requirements that may have arisen at a European, State, autonomous regional government and local level.

The basic environmental requirements applicable to our organisation, which are met under controls, both internally and externally, are shown below:

Environmental management and controlCommitments and audits Among others, our environmental policy commitment is based on the following aspects:

• Compliance with the current legal requirements on environmental matters

• To minimise the significant environmental aspects and prevent contamination

• To manage the equipment and new installations following energy efficiency criteria

• To foster the implementation of renewable energy installations to contribute to sustainable development

• To cater for the proper management and use of resources to seek alternatives for improvement in its processes

One of the essential objectives of an environmental management system is the identification of the environmental aspects.

For this purpose, ATLL annually assesses its environmental aspects in an objective manner in accordance with a methodology based on the comparative evaluation of the data of ATLL’s different activity centres.

To do this reference parameters are used that are accepted and used within the regulatory framework or otherwise in the different technical fields of the speciality relating to the different environmental matters evaluated (dumping of waste waters, wastes, noise, emissions into the atmosphere, energy consumption, auxiliary water consumption, light contamination, contamination of soil, etc.)

This information offers the possibility of setting objectives, milestones, programmes, etc. to improve our environmental management.

The identification of the environmental aspects and the evaluation of its significance therefore form both a part of the initial environmental review as well as of the routine operation of the SGMA.

In both cases it is most important to know the interactions of the organisation with the environment, as this information is essential for the effective maintenance of the daily management and control of the environmental impacts and also for the setting of relevant objectives.

Thus the evaluation of environmental aspects provides ATLL with a series of benefits, such as:

• Allow for the identification of which are the significant environmental aspects

• Reinforce environmental awareness on these aspects

• Evaluate the environmental management carried out for each one of the significant environmental aspects

• Identify the reasons why each aspect is important to ATLL

• To help prioritise the most important actions to be taken with regards to the environmental management of the significant aspects

• Regularly evaluate the environmental improvement (by observing how the significant aspects evolve)

ATLL evaluates its aspects under normal operating conditions, under abnormal and emergency conditions, also analysing the indirect environmental aspects or such aspects that despite intervening in the environment with a specific impact, are not under the organisation’s direct control.

To perform this evaluation and for each environmental aspect identified, the following criteria are assessed:

• Magnitude or intensity• Dangerousness• Frequency• Capacity for control• Effect on the environment• Degree of adequacy of the regulatory framework

Once the environmental aspects have been identified they are evaluated on an annual basis to determine those that have a significant impact on the environment.

From the application of these criteria and the impact evaluation formula established in the aforementioned methodology, one obtains a numerical and objective magnitude for each aspect called Impact units (IU) which allow for comparing the aspects with each other in order to ascertain those that are significant.

Significant Aspects are deemed to be those involving an environmental impact value greater than or equal to 20 environmental Impact Units (IU) as the result of applying the criteria.

When simultaneously to the evaluation of an aspect there is an associated legal breach with it, it is directly considered as a significant environmental aspect with an impact value of 25 IUs.

The following table shows the environmental aspects which have had the greatest environmental incidence for 2012 or the Impact units (IU) obtained for each one of the aspects.

Significant environmental aspects

The environmental aspects with the greatest environmental impact on the production plants are those relating to the energy consumption associated with the water purification process.

In distribution, the most significant impacts are related to the electricity consumption mainly associated with the pumping.

The justification of the interannual trend of the significant environmental aspects is as follows:

PTLL/ELE-1: tendency to increase as the energy consumption increased due to the increase in the treated flow volume.

XAR/ELE-1: tendency to increase as the energy used for water distribution increased in 2012 due to the increase of flow volumes to be distributed.

PAS/ELE-1: tendency to decrease as the energy consumption was lower in 2012 than in 2011.

FON/ELE-1: tendency to decrease as the energy consumption of the centre remained stable. In 2011, the commissioning of the Fontsanta pumping station (PS) involved a considerable increase of the environmental aspect.

TRI/ELE-1: tendency to increase due to the fact that the energy consumption of the centre has increased by more than 900 MWh due to the increase in the operating hours of the C-200 PS (pumping located in the centre).

DES/ELE-1: tendency to increase as the energy consumption increased due to the increase in the treated flow volume.

ATLL also identifies and evaluates indirect environmental aspects, which although their management is not always under direct control, are subject to improvement or environmental damage prevention actions. Among these indirect aspects are the water consumption for the watering of gardens and/or the CO2 emissions derived from energy consumption.

It should be noted that the environmental aspects in emergency situations evaluated have not been considered as significant. Action data sheets are available within the Self-protection Plan to cater for the different emergency situations (fire, chemical spills, chlorine leaks,...).

ATLL’s production centre with the greatest energy consumption is that of the Llobregat ITAM, showing that the trend for the production of drinking water should be mainly focused on the ETAPs, if the resource allows for it. The increase in electric power consumption at the Llobregat ITAM was of 35% compared with the year 2011, due to the increase in water produced.

Other energy consuming installations are the pumping stations, which propel the water towards the supplied towns. At this type of facility energy efficiency criteria are taken into consideration to minimise their energy consumption and optimise their own indicators.

There is an increase in the volume of the reagents used for treatment at the Llobregat ITAM. This is due to the increase in the volume of water treated in the year 2012 (12.4 Hm3) as compared with 2011 (7.38 Hm3). The consumptions indicated are annual consumptions despite the fact that the operation of the Llobregat ITAM has been run directly by ATLL since the month of April 2012.

From the consumption of reagents at each production centre the following tables have been prepared showing the relationship between the volume of reagent used and the volume of treated water.

The raw materials are basically the reagents used in the purification process. These reagents differ depending on the treatment plant as their processes are different. In the evolution of the consumption of reagents for the period from 2009 to 2012 one can observe the change in the use of some of these, such as for example: the aluminium salts and the starch in the Ter ETAP and the chlorine gas used in disinfecting the water at the Llobregat ETAP.

Gestión ambiental24General view of the sludge plant’s of the Llobregat ETAP

Since 2006, the sludge wastes generated in the Ter ETAP in the purification process are sent to the sludge treatment plant.

In 2008 the construction of a sludge plant for the Llobregat ETAP (Abrera) was started in order to improve the quality of the waste waters sent to the Llobregat River and to comply with current legislation.

With the construction and commissioning of the sludge plant, the dumping of residual waters from the washing of filters and purging of decanters, the main source of the sludge generated in the purification process, into public waterways is avoided.

A residue that has been reused in its entirety since 2010 is generated between the two ETAPs. In 2012, the end destination of the sludge was as raw material for a plant for the extraction and treatment of aggregates, to replace quarry sourced aggregates.

Below the volume of sludge generated between both ETAPs is shown in tonnes.
