Title V on the protection of the hydraulic public domain and the quality of the waters of the Royal Legislative Decree 1/2001 of 20 July, which approves the consolidated text of the Waters Act (TRLA) incorporates into Spanish legislation the aspects relating to the protection of the state of the waters in application of the Directive 2000/60/CE of the European Parliament and of the Council of 23 October, establishing a community framework of the waters. In pa rticular, article 92 of TRLA sets out the objectives of water protection and hydraulic public domain, which include, inter alia, preventing deterioration, protecting and improving the state of water; establishing specific measures to reduce contamination by priority substances; and ensuring adequate water supply in good condition. All these objectives are integrated into the environmental objectives for surface water and protected areas regulated by Article 92 bis. Finally, article 92 ter of TRLA requires that each hydrographic demarcation set up programmes to monitor the state of the waters in order to obtain a coherent and comprehensive overview of that state.

Title V of TRLA is developed in Royal Decree 849/1986 of 11 April, which approves the Regulations of the Public Hydraulic Domain (RDPH). However, development in this area, and in particular the protection of water from priority substances, since the Directive 2008/105/EC of the European Parliament and of the Council of 16 December 2008 on the environmental quality standards in the field of the water policy that develops the regime provided for in Article 16 of the DMA and complemented by other subsequent ones, acquires its own sustantivity, being transposed by Royal Decree 60/2011, of 21 January, Thus, in the current edition, the aspects relating to the protection of the state of the water are partially regulated, as provided in the HDR.

In this regard, the monitoring and evaluation of the state, as well as the protection of water from priority substances, constitute a complex and extensive matter which, in the interest of legislative simplicity, should be integrated into a single regulatory text. However, considering that its regulation involves a large number of articles and annexes, it is inappropriate to add to the HDR, despite the fact that it has developed the title V of TRLA since 1986. A new regulatory development that integrates all aspects of monitoring and assessment of the state of water and environmental quality standards (NCA) has therefore been considered appropriate. In any case, and in order to improve the coordination that must exist between the various real decrees that develop the TRLA which prevents the normative dispersion, as well as to contribute to the character of centrality that this real decree must have, it is considered appropriate to modify the RDPH as well as the other two hydrological planning regulations.

The HRD is amended to show that it develops TRLA title V except for the regulation of the criteria for monitoring and evaluating the state of surface water and environmental quality standards, which should be governed by the requirements of the latter. The Regulations of the Public Administration of Water and Hydrological Planning in Development of Titles II and III of the Waters Act, approved by Royal Decree 927/1988 of 29 July, repeal annexes 1 to 4, as well as ministerial orders related to them. These standards were in line with the directives of the 1970s on quality objectives in the waters that have been repealed by the DMA itself, since its objectives have been overcome and integrated by it. Finally, the Regulations on Hydrological Planning (RPH) adopted by Royal Decree 907/2007 of 6 July, which includes, among others, the inclusion of new articles giving them the nature of basic legislation. This complements the transposition to Spanish law of Articles 4, 7, 8, 10, 16 of the DMA, pursuant to the Judgment of the Court of Justice of 24 October 2013, which states that the Kingdom of Spain has breached its obligations, since it has not taken all necessary measures to transpose Articles 4.8; 7.2, and 10.1 and 2, and Annex V.1.3 and V.1.4.1.(i) to (iii) to which 8.2 is referred. In addition, the provisions contained in this royal decree, such as Royal Decree 60/2011 of 21 January, on environmental quality standards in the field of water policy, are repealed; certain sections of Order ARM/2656/2008 of 10 September, by which the instruction on hydrological planning is approved; and Order MAM/3207/2006 of 25 September, by which the complementary chemical instruction is approved.

Fulfilling the environmental objectives foreseen in TRLA includes achieving the good condition of the surface waters which means ensuring the good ecological and chemical state, as well as a good ecological potential and good chemical state for the artificial and highly modified waters. Moreover, and as an additional requirement, the standards and objectives applicable to protected areas must be met. Protecting the state of water requires integrating in water management both chemical and ecological elements, so that the programme of measures is designed and developed in order to achieve the good ecological and chemical state. So far both aspects were regulated through different instruments, so the collection of chemical and biological criteria in a single norm facilitates the knowledge and understanding of the developing water legislation of TRLA Article 92 ter.

II

The assessment of the state of water is an essential element in the implementation of national and European water legislation. The state assessment procedure requires an appropriate legal framework to provide legal security, so that it is applied objectively, certain and homogenously by all hydraulic administrations and is known to all affected. Protecting and achieving good state conditions the program of measures of a hydrographic demarcation. It also determines the level of requirement exercised by the hydraulic administration in the conditions imposed on the holders of the concessions and authorizations on the use of the hydraulic public domain or of the permits of wastewater discharge. It should be recalled that any action or omission that causes the deterioration of the state of the waters constitutes a violation whose qualification will depend on the damage to the water or the environment, and may become a crime. In this regard, Law 26/2007 of 23 October on Environmental Liability provides that damage to water that produces significant adverse effects in the ecological or chemical state has the consideration of environmental damage and therefore must be prevented, avoided or repaired by the person responsible for the activity. Finally, the failure to achieve the good state of the water can lead to the opening of a new procedure of infringement against the Kingdom of Spain for non-compliance with the DMA.

DMA states that Member States must ensure the quality and comparability of the methods used to monitor and evaluate the state of the water. Consequently, it is necessary to have homogeneous and basic criteria for the design of the follow-up programmes that allow for a general, coherent and complete view of the state and quality of the waters, and which are adopted by all the hydraulic administrations in order to ensure a homogeneous, equitable and comparable approach throughout Spain. Follow-up programmes are a basic tool for water management, and should provide the necessary information to assess the effectiveness of the measures taken and the extent to which the targets are met. Its design should allow, among others, to know the state of water; to identify the health of aquatic ecosystems in response to their sustainability, wealth and biodiversity; to determine the extent of water pollution; to assess the consequences of the emission of pollutants from sources of timely and diffuse pollution; to avoid or reduce the deterioration caused by the presence of priority substances; to assess the impact of hydromorphological alterations; etc. In addition, the implementation of the monitoring programmes is essential to monitoring the quality of the waters for specific uses, in particular those used for the supply of populations.

To ensure comparability among member States, the results of biological control and the classifications of their tracking systems should be compared by means of an intercalibration network. The results of the intercalibration exercise have been published in Commission Decision 2013/480/EU of 20 September 2013 setting the values of the classifications of the monitoring systems of member States following the intercalibration exercise. Spain must define reference conditions and class change limits consistent with the values contained in annexes I and II of the aforementioned Decision. To this end, the conditions of reference and limits of state classes applicable to the types of rivers, lakes, reservoirs, transitional waters, coastal and waters very modified by the presence of ports of the Spanish surface waters are published.

In addition, it is necessary that the methods used for follow-up be consistent with international standards or with any other national or international standards that guarantee the provision of quality information and equivalent scientific comparability. As a result of the ongoing process of developing new standards and updating existing standards, the European Standardization Committee has published new standards and others have been abolished. Accordingly, annex V to the WMD has been amended through Commission Directive 2014/101/EU of 30 October 2014, adapting to new requirements. In this line, and in the interests of the quality and comparability of methods, the decree includes the approval of various national norms or protocols to be used by the hydraulic administrations for the monitoring of the waters. These protocols set sampling, laboratory analysis and indicator calculations, in accordance with the provisions of annex V to the DMA.

Royal Decree 60/2011 of 21 January incorporated water protection measures against priority substances as it transposed the Directive 2008/105/EC of the European Parliament and of the Council of 16 December on environmental quality standards in the field of water policy, and Directive 2009/90/EC of the Commission of 31 July establishing the technical specifications of the chemical analysis and the monitoring of the state of the water. It also adapted to the legislation in force the regulations for the protection of water from hazardous substances developed under Council Directive 76/464/EEC of 4 May on pollution caused by certain hazardous substances in the aquatic environment of the Community. The recent adoption of Directive 2013/39/EU of the European Parliament and of the Council of 12 August, amending Directives 2000/60/CE and 2008/105/EC on priority substances in the field of water policy, requires the revision of Royal Decree 60/2011 of 21 January, to adapt it to the new requirements arising from such modification. Similarly, the requirements for the list of observations defined in the Commission ' s Decision for Implementation (EU) 2015/495 of 20 March 2015, which establishes a list of observations of substances for monitoring at the Union level in the area of water policy, in accordance with Directive 2008/105/EC of the European Parliament and the Council.

III

Finally, compliance with Law 27/2006 of 18 July, regulating the rights of access to information, of public participation and of access to justice in the field of the environment; of Law 14/2010 of 5 July, on the infrastructures and the services of geographical information in Spain; and of the international obligations and commitments acquired by the Kingdom of Spain, especially those derived from its inclusion as a State member of the European Union, requires the availability of information It also contributes to the European Parliament and the Council Regulation (EU) No. 1143/2014 of 22 October 2014 on the prevention and management of the introduction and propagation of invasive exotic species, which states that the monitoring system of these species will use the information provided by the existing monitoring systems provided for in Article 8 of the MAL. Finally, the monitoring in coastal waters of the quality elements that contribute to the assessment of the state of the marine environment in accordance with Law 41/2010 of 29 December on the protection of the marine environment promotes the use of the information generated. All this, in relation to the Information System on the state of the water masses (NABIA, for the continental waters, in computer support).

In short, this Royal Decree aims to establish basic and homogeneous criteria for the design and implementation of the monitoring programmes of the state of the surface water masses and for the additional control of the protected areas; to define the criteria, conditions of reference and the limits of the change of class to classify the ecological status of the water masses; to establish the NCA of the priority and preferential substances to classify the state of the polluting waters; and to define the procedure of the

The final part of the decree incorporates various provisions that facilitate the implementation and development of the present royal decree. It also incorporates an additional provision to extend until 30 September 2016 the declaration of drought approved by the Royal Decrees 355/2015, of 8 March, for the scope of the Hidrographic Confederation of Jucar, and 356/2015, of 8 May, for the scope of the Segura Hydrographic Confederation, given the persistence of the drought situation in the aforementioned basins.

IV

The Royal Decree is issued in accordance with the provisions of the TRLA Final Provision, which empowers the Government and the then Minister of Environment, now Minister of Agriculture, Food and the Environment to dictate, in the field of its competence, the necessary provisions for its development and implementation.

This rule has a legal nature of basic legislation in accordance with the provisions of article 149.1.23.a of the Constitution to the extent that it is a necessary complement to ensure the minimum common policy in the protection of the environment applicable to all hydrographic demarcations, so that it acts as a prevalent competitional title, since in the area of waters there are several different jurisdictional titles for the State. As the constitutional case law has indicated, by all Judgment 227/1988 of 29 November, the rule is limited to "establishing some requirements of principle, in order to guarantee the quality of the continental waters and their environment, without diminishing the competence of the autonomous communities to develop or complement those general rules and to execute them in the field of their administrative competences on the hydraulic public domain" so that they can easily dictate the environment. 149.1.23.a of the Constitution." On the other hand, its projection in the intercommunal basins will operate as a full title for its application by the basin agencies, while there is no other authority in the demanium than the Hydrographic Confederations. In this way, a uniform application is ensured in the state-run hydrographic demarcations and a common standard minimum in the rest of the basins, which will meet the requirements of European Union Law. In any case, the established criteria are understood as minimum requirements and leave room for the autonomous regulations allowing legislative development by the Autonomous Communities with environmental competencies.

This royal decree has been reported by the Environmental Advisory Council and the National Water Council. The autonomous communities and the representative entities of the affected sectors have been consulted and have been submitted to public information.

By virtue, on the proposal of the Minister of Agriculture, Food and Environment, in accordance with the Council of State and prior deliberation of the Council of Ministers at its meeting on 11 September 2015,

3. The follow-up programmes will be reviewed every six years in response to the results of the study of the impact of human activity on the state of surface water and will be collected in the basin hydrological plan.

4. The information generated from the follow-up programmes will be collected in the information system on the status and quality of the waters regulated in Article 30.

Article 5. Monitoring programme.

1. The monitoring programme aims to obtain a comprehensive and comprehensive view of the state of the water masses.

It is composed of:

(a) The "subprogramme to monitor the general state of the waters", which will allow the assessment of the general state of the surface waters and of the changes or trends experienced by these long-term water masses as a result of widespread anthropogenic activity.

(b) The "subprogramme of reference", which will allow to evaluate long-term trends in the state of the water masses due to changes in natural conditions, as well as to establish specific reference conditions for each type of water mass.

(c) The "subprogramme of control of emissions to the sea and cross-borders", which will allow the estimation of the polluting burden that crosses the Spanish border and that which is transmitted to the marine environment.

2. The results of this programme will enable the effective and efficient design of future control programmes, as well as the availability of information to complement and validate the study of the impact of human activity on the state of surface water provided for in article 41.5 of TRLA, and which is part of the overall study of demarcation that precedes the development and proposed revision of the hydrological plan.

3. The criteria for the design and implementation of the subprogrammes under the monitoring programme are defined in annex I A.

Article 6. Operational control program.

It will be carried out on all the water masses identified at risk of not meeting environmental objectives in the light of the results of the pressure and impact analysis or the outcome of the state monitoring subprogrammes, and on which contaminants are poured from the list of priority substances contained in annex IV.

2. The information associated with each station of the operational control programme will indicate the risk pressures on the water mass by applying the classification in annex I B.

At the very least, the masses of water at risk will be identified by hazardous substances from punctual sources and pesticides from agrarian sources, and they will be called respectively, control of hazardous substances of punctual origin and control of pesticides of agrarian origin.

3. The criteria for the design and implementation of the operational control programme are defined in annex I B.

Article 7. Research control programme.

1. The research control programme will be implemented if the origin of non-compliance with environmental objectives is unknown; if monitoring indicates the improbability of the objectives and an operational control has not been implemented to determine the causes for which they have not been achieved; and to determine the extent and impact of accidental contamination.

This control will define the programme of measures required to meet environmental objectives and, where appropriate, specific measures to remedy the effects of accidental contamination.

2. Controls to determine the specific contaminants of the basin contained in Annex VI shall be included in this programme, and in particular the Observation List regulated in Article 25.

Article 8. Requirements for additional control of the water masses of the registry of protected areas.

1. In the following areas of TRLA ' s protected area registry, control programmes will at least apply these additional requirements:

(a) The water masses for the production of water for human consumption, and from one or more points of capture, provide an average of more than 100 cubic meters per day, will be subject to additional controls of priority substances and pollutants dumped in significant quantities; paying special attention to the substances affecting the state and regulated in annex I to Royal Decree 140/2003 of 7 February, which establishes the sanitary quality of consumption. The selected sampling stations or points for this control will be identified as a Water Control Programme for the Supply.

(b) The water masses in which declared areas of protection of economically significant aquatic species are located will be subject to additional monitoring at the environmental control point designated by the environmental body for the control of the causes of pollution that may affect such species. The sampling points selected for this control will be identified as an Environmental Control Programme for Areas of Significant Aquatic Species from an Economic Point of View.

These areas include those for the production of mollusks and other marine invertebrates, which will take into account the follow-up requirements set out in Royal Decree 345/1993 of 5 March, establishing the standards of quality of the waters and the production of mollusks and other marine invertebrates.

(c) The water masses in which areas declared as bath waters are located will be subject to additional monitoring at the environmental control point designated by the environmental body for the control of the causes of contamination that may affect the bathing waters, according to the Royal Decree 1341/2007 of 11 October on the management of the quality of the bathing waters. The sampling points selected for this control will be identified as an Environmental Water Control Programme.

(d) The water masses affected by nitrate pollution pursuant to Royal Decree 261/1996 of 16 February on the protection of water against the contamination produced by nitrates from agricultural sources shall be included in the operational control programme, and shall take into account the specifications set out in the norm by which vulnerable areas are declared as a protected area. The stations or sampling points selected for this control will be identified as a Water Control Program affected by agrarian nitrates.

(e) The water masses that include areas declared sensitive in accordance with Royal Decree 509/1996 of 15 March on the development of the Royal Decree-Law 11/1995 of 28 December, establishing the rules applicable to the treatment of urban wastewater, shall be included within the operational control programme, and shall take into account the specifications set out in the same rule designating such areas as a protected area. The stations or sampling points selected for this control will be identified as a Water Control Programme in areas sensitive to urban spills.

(f) The water masses located in the habitat protection zones or species of the Natura 2000 network will be included in the operating control program when they are considered to be at risk of failing to meet their environmental objectives of the water mass. The selected sampling stations or points for this control will be identified as Water Control Program in habitat or species protection zones.

2. To meet these additional requirements, follow-up will be carried out in accordance with the criteria set out in annex I C.

PART III

Assessment of the state of the surface water masses

Article 9. General provisions on state assessment.

1. The state of the surface water masses will be determined by the worst value of its ecological and chemical state.

2. The ecological state of surface waters will be classified as very good, good, moderate, poor or bad. In order to classify the ecological status of the surface water masses, the indicators of the quality elements set out in the following articles, the values of Annex II and the calculated NCAs for specific pollutants or, where appropriate, Annex V NCAs for preferred substances will be applied.

Annex I

Basic criteria for the design and implementation of follow-up programmes

A. Monitoring Program: Design and Implementation Criteria

The monitoring programme aims to obtain a comprehensive and comprehensive view of the state of the water masses and is composed of the subprogrammes listed in Article 5, that is:

A.1) Follow-up to the general state of the waters.

A.2) Baseline.

A.3) Sea and transboundary emission control subprogramme.

As defined in Article 3, it is understood by sampling station to the set of sampling points used for the assessment of the state of the mass of water, being a sampling point the geographical location of sample taking.

Therefore, each mass of water must have only one station that may contain several sampling points. When a sampling station contains several points, and it is not possible to associate geographical coordinates, the centre of the water mass can be applied to the station.

A.1) Follow-up to the general state of the waters.

Object. The "subprogramme to monitor the general state of the waters" (or to monitor the state) aims to gather the necessary information to carry out the assessment of the general state of the surface waters and of the changes or trends experienced by these long-term water masses as a result of widespread anthropogenic activity.

The results of this control will be reviewed and used, in combination with the pressure and impact analysis procedure (Article 41 of TRLA), to determine the requirements of the control programmes in current and future watershed plans.

Selection of sampling stations. The sampling stations should be located in masses of water that reflect the heterogeneity of demarcation, according to the existing types of masses of water, the anthropogenic pressures to which they are subjected and the assessment of the chemical, ecological and general state.

The number of stations included in the subprogramme will depend on the heterogeneity of the basin, and the more heterogeneous it is. In any case, a number of stations will be selected which is statistically representative of demarcation.

The control will be ensured at least at points where:

The level of water flow is significant within the hydrographic demarcation set, including those points in large rivers with a basin exceeding 2,500 km2.

The volume of water is significant within the whole of hydrographic demarcation, including large lakes and reservoirs.

The conditions of the surrounding aquatic environment are not under the direct and immediate influence of a foci of pollution or subject to the tides.

The results of this subprogramme allow the evaluation of the state of a mass of water to be extrapolated to others of the same type that have not been shown, provided that they are subject to the same pressures as the sampled water mass.

Quality elements and sampling frequencies. The State Monitoring Subprogramme should monitor all biological, hydromorphological and physicochemical quality elements, as well as the priority list substances that are poured and the pollutants dumped in significant quantities known as specific pollutants.

At the very least, the stations will be shown for one year within the period covered by the watershed plan. Exceptionally, control can be carried out once every three updates of the basin hydrological plan in the water masses classified in good condition in the previous planning period, and provided that from the examination of the incidence of human activity carried out through the exercise of pressures and impacts, there is no evidence that the pressures to which the water masses are subjected have been modified.

When it is deemed necessary to increase the level of confidence in the exercise of pressures and impacts, the number of water masses will be increased to control in order to complete and validate the risk assessment of achieving the environmental objectives of the water masses.

During the control year, the elements will be controlled according to the following sample frequencies:

Biological quality elements will be controlled once, except the phytoplankton that will be at least twice, adapting the sampling period to the characteristics of the water mass to be monitored.

Hydromorphological quality elements will be controlled once, except the hydrological regime that will be continuous for rivers and once a month for lakes.

General physicochemical quality and specific pollutants will be controlled at least every three months, although monthly control is recommended.

Priority substances in water will be controlled on a monthly basis. However, when the analysis is carried out in sediment or biota, the frequency will be indicated in paragraph D of this annex.

In short, annual frequencies are:

♪ Water mass with a significant tendency to eutrofization.

In specific and justified cases, greater intervals may be applied depending on the expertise and the expert judgement.

The dates chosen for the follow-up will be such that the impact of the seasonal variation of the results is minimized to the maximum, thus ensuring that the results reflect the changes in the water mass due to changes caused by anthropogenic pressure and natural conditions. In any case, detailed specifications will be followed in official sampling protocols.

A.2) Baseline.

Object. The reference subprogramme aims to assess long-term trends in the state of the water masses due to changes in natural conditions, as well as to establish specific reference conditions for each type of water mass.

Selection of sampling stations. Sampling stations should be located in water masses that do not present alterations, or that present minor alterations, which allow the conditions normally associated with the type of water mass in the absence of major pressures.

In the interest of homogeneity and comparability of results, the Directorate General of Water, in coordination with hydrographic demarcations, will establish the criteria and procedure for the validation of the reference stations.

Quality elements and sampling frequencies. The baseline subprogramme should show at least all biological, hydromorphological and physicochemical quality elements.

At the very least, the stations will be shown for one year within the period covered by the watershed plan.

Biological and hydromorphological quality elements will be controlled once, except the phytoplankton that will be twice. General physicochemical quality elements will be controlled when you come to show biological elements.

When a reference station is integrated into the status monitoring subprogramme, the design criteria provided for in A.1) will be applied as long as they are more demanding.

A.3) Sea and transboundary emission control subprogramme.

Object. The subprogramme on the control of emissions to the sea and cross-borders aims to estimate the polluting burden that crosses the Spanish border and is transmitted to the marine environment.

Selection of sampling stations. Sampling stations should be located in the water masses crossing the border of a member State and those that discard the marine environment. Its selection will cover:

Convention on Cooperation for the Protection and Sustainable Use of the Waters of the Spanish-Portuguese Watersheds, made "ad referendum" in Albufeira on 30 November 1998 (Albufeira Convention).

Convention on the Protection of the Marine Environment of the North-East Atlantic (OSPAR Convention), ratified by Spain on 25 January 1994.

Convention for the Protection of the Mediterranean Sea from Pollution (Barcelona Convention), ratified by Spain on 17 February 1999.

Administrative agreement between Spain and France on water management, signed in Toulouse on 15 February 2006.

Quality elements and sampling frequencies.

The quality elements and sampling frequencies applicable in the stations integrated in the Sea and Transboundary Emissions Control Subprogramme are those provided for in the emission control programme defined in the OSPAR, Barcelona and Albufeira Convention.

When an emissions control station to the sea and cross-borders is integrated into the status monitoring subprogramme, the design criteria provided for in Sub-paragraph A.1) shall be applied as long as they are more demanding.

Sub-paragraph B. Operating Control Program: Design and Implementation Criteria

Object. As set out in Article 6, the operational control programme aims to determine the state of the water masses at risk of not meeting environmental objectives, as well as to assess the changes in the state of these masses as a result of the action programmes.

The results of the control allow the establishment or confirmation of the state of the water masses and the evaluation of the results of the measures programs.

The information associated with each station of the operating control program will indicate the risk pressures on the water mass using the following classification:

1. Significant point sources.

2. Significant diffuse sources.

3. Significant water extracts.

4. Significant water regulations.

5. Significant morphological alterations.

6. Other significant anthropogenic incidences.

7. Uses of the floor.

Selection of sampling stations. The sampling stations will be located in the following water masses:

Water mass at risk of not achieving environmental objectives in the light of the result of pressure and impact analysis or the result of state monitoring programmes.

Water materials containing contaminants from the list of priority substances listed in annex IV.

Considering that each mass of water contains a single station and that each station may contain several sampling points will apply the following criteria for selecting the points and masses of water to show:

Masses at risk due to significant pressures from point sources:

A sufficient number of points will be selected in each mass to assess the magnitude and impact of these pressures.

When a mass is subject to various pressures from specific sources, points may be selected to assess the magnitude and impact of such pressures as a whole.

The stations corresponding to these masses will be identified as pollutant control stations of specific origin.

Among them, the stations will be identified in masses of water at risk for the dumping of dangerous substances, identifying themselves as the Control Station for hazardous substances of specific origin.

Masses at risk due to significant pressures from diffuse sources:

A sufficient number of points will be chosen in the selected masses to assess the magnitude and impact of these pressures.

The selection of these masses will be made so that they are representative of the risks resulting from the existence of pressures from diffuse sources.

When the diffuse source is agrarian, the stations corresponding to these masses will be identified as pesticide control stations of agrarian origin.

Among them, the water mass stations at risk for pesticides of agrarian origin will be identified, identifying themselves as a pesticide control station of agrarian origin.

Masses at risk due to significant hydromorphological pressures:

A sufficient number of points will be chosen in the selected masses to assess the magnitude and impact of these pressures.

The selection of the masses will indicate the global impact of the hydromorphological pressure to which all the masses are subjected.

Quality elements and sampling frequencies. The Operational Control Programme should show:

The biological quality elements most sensitive to the pressure to which the mass of water is subjected and the most sensitive indicators of such elements.

As a support to this sampling, when biological quality elements are to be sampled, the general physicochemical quality elements can be sampled if deemed necessary.

All priority substances poured and pollutants poured into significant quantities.

The hydromorphological quality elements most sensitive to the pressure to which the mass of water is subjected and the most sensitive indicators of such elements.

The stations will be shown throughout the period covering the watershed plan. However, the operational control programme may be modified during the watershed plan period in the light of the information gathered from the pressure and impact study or the state monitoring programmes. In particular, periodicity may be reduced when the impact is deemed to be not important, the corresponding pressure removed or the good condition reached.

The elements will be controlled with the following sampling frequencies:

The biological quality elements most sensitive to the pressure to which the mass of water is subjected will be controlled according to the following distribution: phytoplankton twice a year, diatoms and macro-invertebrates once a year, and macrophytes and fish every three years.

The hydromorphological quality elements most sensitive to the pressure to which the mass of water is subjected will be controlled every six years, except the hydrological regime that will be continuous for rivers and monthly for lakes.

General physicochemical quality and specific pollutants will be controlled at least every three months, although monthly control is recommended.

Priority substances in water will be controlled on a monthly basis. However, when the analysis is carried out in sediment or biota, the frequency will be indicated in paragraph D of this annex.

♪ Water mass with a significant tendency to eutrofization.

In specific and justified cases, greater intervals may be applied depending on the expertise and appreciation of specialists.

The dates chosen for the follow-up will be such that the impact of the seasonal variation of the results is minimized to the maximum, thus ensuring that the results reflect the changes in the water mass due to changes caused by anthropogenic pressure and natural conditions. In any case, detailed specifications will be followed in official sampling protocols.

Sub-paragraph C. Additional requirements for monitoring protected areas

Monitoring and operating programs to which the water masses are subjected will be complemented to meet the following additional requirements.

C.1) Water control for supply.

Object. This control is composed of the set of sampling points that allow the monitoring of protected areas for water harvesting for the production of human consumption water.

Selection of sampling points:

The water masses will be controlled which provide an average of more than 100 cubic meters per day for population supply.

A sufficient number of sampling points will be chosen in the water masses to assess the magnitude and impact of the pressures to which it is subjected.

Quality elements and sampling frequencies:

The control over the priority substances dumped and the contaminants dumped in significant quantities will be carried out with special attention to the substances affecting the state and which are regulated in annex I to Royal Decree 140/2003 of 7 February, which establishes the sanitary criteria for the quality of human consumption water.

The additional controls will be carried out with the following periodicity:

Population supplied

Periodicity

10000 inhabitants

Quarterly

10000 to 30,000 inhabitants

8 times a year

30,000 inhabitants

Monthly

C.2) Water control in habitat or species protection zones.

Object. This control is made up of a set of sampling points that allow the monitoring of the protected areas included in the Natura 2000 network in which the maintenance or improvement of the state of water constitutes an important factor for the protection of habitats or species.

Selection of stations or sampling points. The stations will be located in the water masses at risk of not achieving environmental objectives, understanding for them to achieve good status and meet the standards and objectives of protection derived from the protection of species and habitats. The risk is assessed through the analysis of pressures and impacts and the result of the state's monitoring programs.

Quality elements and sampling frequencies:

The quality elements and sampling frequencies will be defined according to the same criteria of design and implementation of the Operational Control Programme, developed in paragraph B of this annex.

When the protection of species or habitats requires the establishment of additional quality elements and more demanding sampling frequencies, it must be reflected in the Natural Space Management Plan, following agreement between the hydrographic demarcation and the competent Authorities in the management of the spaces.

This control shall be maintained until the areas conform to the water requirements of the legislation under which they have been designated and when they reach the good condition.

Sub-paragraph D. Specific requirements for monitoring priority and pollutant substances

Monitoring and operational control programmes will be complemented to meet the following specific requirements for monitoring priority and contaminating substances.

Object. Monitoring priority and pollutant substances has two objectives:

Assess the compliance of the NCA, expressed as an annual average or maximum admissible concentration, and referred to water or biota.

Analysis of long-term trends of certain substances in sediment and biota.

Selection of sampling points:

A sufficient number of points will be chosen in the water masses to assess the magnitude and impact of the punctual and diffuse sources of these substances.

For the control of the contamination from specific sources, and for the purposes of the representativeness of the sample, the sampling point must be placed outside the area of the flow defined in article 26 of this royal decree.

Quality elements and sampling frequencies. NCA control in water, sediment and biota:

Article 20 of this Royal Decree establishes the substances to be measured in water or biota. Article 21, regulates the possibility of using alternative biota dies and taxons. Article 22 sets the conditions for the use of complementary matrices.

In addition to the analysis of the concentration of priority substances, the control can be complemented by the analysis of the parameters related to bioavailability in order to evaluate the compliance of the NCA.

For the water matrix, the sample rate is set in paragraphs A and B of this annex, being monthly for priority and quarterly substances for the other contaminants, although it is recommended to be monthly.

For the sediment or biota matrix, follow-up will be carried out at least once a year, unless technical knowledge and expert opinion warrant another interval.

Substances identified with numbers 5, 21, 28, 30, 35, 37, 43 and 44 of annex IV A are persistent, bioaccumulable, toxic and ubiquitous substances (PBT ubiquitous). For these substances, the competent bodies may undertake less intensive follow-up to the requirement in the preceding paragraph. Tracking should have a triennial frequency on a guideline basis, except if technical knowledge and expert opinion warrant another interval.

This condition may be applied when monitoring is representative and a statistically sound baseline is already available for the presence of such substances in the aquatic environment.

Analysis of long-term trends in sediment and biota:

Article 24 of this Royal Decree sets out the substances on which the analysis of the long-term trend regarding concentrations should be carried out in order to ensure that such concentrations do not significantly increase in either sediment or biota.

For guidance, sediment or biota tracking may have a triennial frequency, except if technical knowledge and expert opinion warrant another interval.

In line with the specificities of analytical control, substances can be distinguished as:

Annex III

Technical criteria and specifications for the monitoring and classification of the state of the waters

A. Sample procedures, analysis and calculation of indicators

The methods used to control the parameters of each type shall be in accordance with the international standards listed in section 1.3.6 of annex V to Directive 2000/60/CE, to the extent that they relate to control, or to any other national or international standards that guarantee the provision of quality information and equivalent scientific comparability in compliance with the provisions of Directive 2014/101/EU of the Commission, of 30 October 2014, which amends the European Parliament Directive 2000/60/CE.

In the interest of comparability and homogeneity, the sampling and analysis of the quality elements for the classification of the state of the surface water masses will be carried out following the official protocols developed for this purpose by the Ministry of Agriculture, Food and Environment or by the Autonomous Communities in the exercise of their competences and which are listed below:

Sub-paragraph B. Criteria for the combination of indicators of biological quality elements

B.1) General and specific criteria:

1. The classification of the ecological state of a mass of water is evaluated through an iterative process, schematiced in the following figure, which includes the analysis of the values of biological quality indicators, followed by the analysis of general chemical and physicochemical indicators; and finally, hydromorphological indicators are analyzed.

2. Initially, the degree of deviation between the values of biological quality indicators observed with the values of the reference conditions set out in Annex II is calculated. Where these indicators correspond to different pressures or different assessments, the most restrictive value will be adopted.

3. When the values of several applicable indicators of the same quality element are available and sensitive to the same pressure or a general pressure gradient, the results of the indicators should be combined to obtain a single status value of the biological quality element in question.

4. When indicators correspond to different pressures, the most restrictive value will be adopted for the purpose of classifying the ecological state.

5. In the interest of homogeneity and comparability of results, the Ministry of Agriculture, Food and the Environment, in coordination with hydrographic demarcations, will define specific criteria for combining indicators corresponding to biological quality elements that will be approved by Instruction and incorporated into this annex.

The iterative procedure to assess the ecological state of the waters is reflected in the following scheme:

Imagen: img/disp/2015/219/09806_007.png

B.2) Level of trust in the classification of ecological status or potential:

1. The assessment of the ecological status or potential of the surface water masses, for the purpose of the basin hydrological plan, will be carried out from the available data series of a complete planning period of 6 years.

2. The following criteria shall be taken into account:

(a) When the results are homogeneous, the indicators will be calculated from the available data series of the full 6-year planning period, which is being revised.

(b) When the results present a growing, declining or variable trend, the indicators will be obtained from the available data series of the last year of the period.

In this case, the data that are representative of the quality or state of the water mass should be analyzed by discarding:

Data with high uncertainty, in which case the frequency of control should be increased.

Data obtained in circumstances of temporary deterioration caused by exceptional causes of both natural and force majeure or which could not reasonably be foreseen.

Data obtained under accident circumstances.

Data obtained in circumstances of circumstantial deterioration of the state due to eventual pressures.

Data of doubtful reliability due to unknown causes, in which case the mass of water should be included in the research control programme.

It should be justified if the data obtained in the circumstances described above are decided.

3. Statistical analysis of available data series should be carried out to estimate the measurement uncertainty of the results of the control programmes. This study will include sampling methods and results.

4. The level of confidence in the classification of quality elements and the ecological state will be calculated from the indicators obtained and corresponding to a full period of planning.

5. The level of trust in the assessment of the ecological state or potential will be classified as high, medium and low depending on:

The measurement uncertainty of the sampling data of the control programmes used to obtain the indicators.

The availability of indicators for all quality elements or only for those more sensitive to pressures.

The levels of confidence in the classification of biological, physicochemical or chemical and hydromorphological quality elements.

Coherence with the data of the pressures to which the surface water masses are exposed.

6. The assessment of the ecological status or potential carried out on the basis of the values of the reference conditions obtained either with high uncertainty or from insufficient data by interpolation and expert criteria, shall be considered with a low level of trust.

7. In the interest of comparability and homogeneity, the Ministry of Agriculture, Food and the Environment, in coordination with hydrographic demarcations, will develop the criteria for calculating the level of confidence of the assessment of the ecological state or potential to be approved by Instruction and incorporated into this annex.

Sub-paragraph C. Technical Specifications of Chemical Analysis

C.1) Analysis methods:

(a) The chemical analysis methods, including the field and laboratory methods used for the purpose of evaluating the results of the control networks established for the monitoring of the status contained in Article 42.1.d of the TRLA, and in particular the substances listed in Annexes IV, V and VI, shall be validated and documented in accordance with EN ISO/IEC-17025 or other internationally accepted equivalent standards.

(b) All methods of analysis applied will be based on a measurement uncertainty of 50% or less (k=2) estimated at the level of the NCAs and a quantification limit equal to or less than a value of 30% of the relevant NCAs.

(c) In the absence of a relevant NCA for a particular parameter, or in the absence of an analysis method that meets the criteria of point C.1.b, the analysis will be carried out following the best available techniques that do not carry disproportionate costs.

C.2) Average value calculation:

(a) If the measured amounts of the physicochemical or chemical parameters of a given sample are below the quantification limit, the measurement results will be set at half of the corresponding quantification limit for the calculation of the average values.

(b) If a calculated average value of the measurement results referred to in subparagraph (a) is less than the quantification limits, the value shall be considered “inferior to the quantification limit”.

(c) Paragraph C.2.a shall not apply to the parameters that are aggregates of a particular group of physicochemical or chemical parameters, including their relevant metabolization, degradation and reaction products. In these cases, the results below the quantification limit of the different substances will be set at zero.

C.3) Quality assurance and control. The laboratories, for the sake of guarantee and quality control of their results:

(a) They will apply quality management practices in accordance with EN ISO/IEC-17025 or other internationally accepted equivalent standards.

(b) They should demonstrate their analytical capabilities of the corresponding physicochemical or chemical parameters by:

I. Participation in aptitude testing programmes that include the methods of analysis provided for in subsection C.1).a) at concentration levels that are representative of water monitoring programmes.

ii. Analysis of available reference materials that are representative of samples collected with appropriate concentration levels in relation to relevant ACSs.

(c) The aptitude test programmes provided for in point C.3).b).i of this annex shall be organized by accredited organizations or by national or international recognized organizations that meet the requirements of the ISO/IEC 43-1 guide or other internationally accepted equivalent standards.

The results of participation in these control programs will be evaluated according to the score systems set out in ISO/IEC 43-1, ISO-13528 or any other internationally accepted equivalent standard.

C.4) Specifications on metal analysis. In the analysis of metals four parameters can be differentiated: dissolved metal, metal, total metal and metal accumulated in the suspended matter, with the following definition and pretreatment of sample:

(1) CAS: Chemical Abstracts Service.

(2) When groups of substances have been selected, unless they are explicitly stated, certain typical representatives are defined in the context of the NCA fixation.

(3) Three kinds of substances are distinguished: priority, dangerous priority and other contaminants.

Priority substances are those that pose a significant risk to the community aquatic environment, or through it, including the risks of this nature for the waters used for the capture of drinking water, and regulated through Article 16 of Directive 2000/60/CE, of the European Parliament and of the Council of 23 October. These substances include priority hazardous substances (Article 16.3 of Directive 2000/60/CE).

Other contaminants: they are not priority substances but pollutants for which FTAs are identical to those established in the legislation on hazardous substances applicable prior to the adoption of Directive 2008/105/EC of the European Parliament and the Council of 16 December 2008 on environmental quality standards in the field of water policy.

(4) This parameter is the NCA expressed as an average annual value (NCA-MA). Unless otherwise specified, it applies to the total concentration of all isomers.

(5) Continental surface waters include rivers and lakes and artificial or highly modified masses of water.

(6) This parameter is the NCA expressed as the maximum admissible concentration (NCA-CMA). When the NCA-CMA column indicates "Not applicable", it is considered that NCA-MA values protect against short-term pollution peaks in the case of continuous spills, as they are significantly lower than the calculated values based on acute toxicity.

(7) Unless otherwise indicated, the NCAs of the biota refer to fish. Alternatively, another taxon of the biota or another matrix may be followed, provided the applied NCAs offer an equivalent level of protection. For substances with numbers 15 (fluorant) and 28 (HAP), the NCA of the biota refers to crustaceans and molluscs. For the purpose of evaluating the chemical, the monitoring of fluorantene and PAHs in fish is not adequate. For the substance with the number 37 (dioxins and similar compounds), the NCA of the biota refers to fish, crustaceans and molluscs in accordance with point 5.3 of the annex to the Regulation (EU) No. 1259/2011 of the Commission, of 2 December 2011, amending the Regulation (EC) No. 1881/2006 in relation to the maximum contents of dioxins, PCB.

(8) With regard to the group of priority substances included in the brominated diphenylepters (n. 5), ACS refers to the sum of congeners ' concentrations n. 28, 47, 99, 100, 153 and 154.

(9) Only tetra, penta, hexa and heptabromodiphenyléter compounds ( CAS 40088-47-9, 32534-81-9, 36483-60-0, 68928-80-3, respectively).

(10) In terms of cadmium and its compounds (n. 6), the values of the NCAs vary depending on the hardness of the water according to the five categories (class 1: ≤ 40 mg CaCO3/l, class 2: from 40 to 50 mg CaCO3/l, class 3: from 50 to 100 mg CaCO3/l, class 4: from 100 to 200 mg CaCO3/l, and class 5: ≥ 200 mg CaCO3/l).

(11) No indicative parameter is indicated for this group of substances. The indicative parameter or parameters should be defined by the analytical method.

(12) Total DDT includes the sum of the isomers 1,1,1-tricloro-2,2-bis(p-chlorophenyl)-etano (n.o CAS 50-29-3; n.o EU 200-024-3); 1,1,1-tricloro-2-(o-chlorophenil)-2-etano (n.o CAS 789-02-232; n.o

(13) These NCAs refer to bioavailable concentrations of substances.

(14) Nonilfenol (CAS 25154-52-3, EU 246-672-0), including 4-nonilphenol isomers (CAS 104-40-5, EU 203-199-4) and 4- nonilfenol (ramified) (CAS 84852-15-3, EU 284-325-5).

(15) Octilphenol (CAS 1806-26-4, EU 217-302-5), including isommer 4-(1,1',3,3'-tetramethylbutyl)phenol (CAS 140-66-9, EU 205-426-2).

(16) With regard to the group of priority substances of polycyclic aromatic hydrocarbons (HAP) (No. 28), biota NCAs and corresponding NCA-MA in water refer to the concentration of benzo(a)pireno, which are based on toxicity. Benzo(a)pireno may be regarded as a marker of the other HAPs, as only such substance should be monitored for purposes of comparison with the NCAs of the biota or the corresponding NCA-MA in the water.

(17) Including benzo(a)pireno (CAS 50-32-8, UE 200-028-5), benzo(b)fluorantno (CAS 205-99-2, EU 205-911-9), benzo(g, h, i)perileno (CAS 191-24-2, EU 205-883-8), benzo(k)fluorant (CAS 207-08-9, UE 205

(18) Including the Cathion of Tributylsten (CAS 36643-28-4).

(19) There is insufficient information available to establish an NCA-CMA for these substances.

Sub-paragraph B. Implementation of the environmental quality standards set out in paragraph A

1. A surface water mass meets the NCA-MA when the arithmetic mean of concentrations measured different times during the year, at each point of control representative of the water mass, does not exceed the norm.

The calculation of the arithmetic mean, the method of analysis used and, where there is no appropriate method of analysis that meets the minimum criteria of realization, the mode of application of the NCA shall be adjusted to the performance actions by which technical specifications are adopted for the technical control and quality of analytical results, in particular those contained in annex III C.

2. It is considered that a surface water mass meets the NCA-CMA when the measured concentration at any point of control representative of the water mass does not exceed the norm.

However, the competent bodies may introduce statistical methods, such as the percentile calculation, to ensure an acceptable level of confidence and precision in the determination of compliance with NCA-CMA.

In the event that the competent bodies introduce them, these statistical methods must comply with detailed rules established in accordance with the review procedure provided for in Article 9.2 of Directive 2008/105/EC of 16 December on environmental quality standards in the field of water policy.

3. The water NCAs set out in the present annex are expressed as total concentrations throughout the water sample.

As an exception to the first paragraph, in the case of cadmium, lead, mercury and nickel (hereinafter "metal"), the water NCAs refer to the dissolved concentration, i.e., the dissolved phase of a sample of water obtained by filtration through a membrane of 0.45 μm or any other pretreatment equivalent, or, when specifically indicated, to the biodisponible concentration.

When comparing the results of the controls with the corresponding NCA, they may be taken into account:

(a) Natural concentrations of metals and their compounds, when such concentrations fail to meet the value set by the corresponding NCA.

(b) Hardness, pH, dissolved organic carbon or other water quality parameters that affect the bioavailability of metals, for which bioavailable concentrations are to be determined by appropriate bioavailability models.

4. The Ministry of Agriculture, Food and the Environment, for the purposes of standardization and comparability of results, may develop methodological guides specifying and developing the procedures for implementing the NCAs set out in paragraph A.

Sub-paragraph C. Technical specifications on the observation list

1. The observation list integrates the set of substances selected among those of which the available information indicates that they may pose a significant risk to or through the aquatic environment and for which the tracking data are insufficient, so data should be collected at the European Union level. The European Commission takes action to develop and update the list.

2. Substances or groups of substances that make up the first observation list, as well as the indicative analytical method and the acceptable maximum detection limit of the method are defined in the Commission's Decision for Implementation (EU) 2015/495 of 20 March 2015 establishing a list of substances for follow-up purposes at the Union level in the area of water policy, in accordance with Directive 2008/105/EC of the European Parliament and the Council.

3. The duration of a continuous follow-up period of the observation list for any individual substance shall not exceed 4 years.

4. The tracking of each substance in the list will be carried out in selected representative stations, for at least a period of 12 months. Monitoring for substances included in the first observation list will begin by 14 September 2015. Follow-up to a new substance will begin within six months of its inclusion in the observation list.

5. Pursuant to Article 8 ter.3 of Directive 2008/105/EC of 16 December on environmental quality standards in the field of water policy, the number of follow-up stations for Spain is at least 20.

6. When selecting representative stations, frequency and timetable for each substance, the use of the substance and its possible presence will be taken into account. The frequency of follow-up will not be less than once a year.

7. Follow-up to a particular substance may be suspended if sufficient, comparable, representative and recent data are available from existing follow-up programmes or studies, provided that the technical guidelines developed by the Commission are followed.

8. The provisions on the Observation List shall be accommodated in the technical specifications defined by the European Commission to facilitate the follow-up of these substances, as well as in the interests of comparability and representativeness.

Annex VII

Procedure for the establishment of the environmental quality standard

In order to establish the NCA in water, sediment or biota, the following provisions shall be acted in accordance with the provisions set out below.

1. Where possible, data will be obtained, both on time and on time, for the taxa mentioned below, provided that they are relevant to the category and type of water masses, as well as other aquatic taxa available.

The taxon base set consists of:

Algae or macrophytes.

Daphnia or representative organisms of salt water.

Fish.

Appropriate security factors shall be determined in accordance with the nature and quality of the available data, with the indications contained in part II, item 3.3.1 of the "Technical guidance document in support of Commission Directive 93/67/CEE of 20 July 1993 on the risk assessment of the new reported substances and the Regulations (EC) No. 1488/94 of the Agency of 28 June 1994 on the assessment of the risk of the existing substances,

Security factor

At least one specific L(E)C50 of each of the three trophic levels of the base set.

1000

A protracted NOEC (species or Daphnia or a representative organism of saltwaters).

100

Two prolonged NOECs of species representing two trophic levels (speces or Daphnia or a representative organism of saltwater or algae).

50

Prolonged NOEC of at least three species (usually ctiological fauna, Daphnia or a representative organism of saltwater and algae) that represent three trophic levels.

10

Other cases, including field data or model ecosystems, which allow the calculation and application of more precise security factors.

Case-by-case evaluation.

L(E)C50: lethal or effective average concentration. NOEC: concentration of unobserved effects.

2. In the event that data on persistence and bioaccumulation are available, the final value of the FTA should be taken into account.

3. The NCA thus derived should be compared to the possible evidence from field studies. In the event of anomalies, the derivation should be revised to calculate a more precise security factor.

4. The resulting NCA shall be subject to a critical review of experts and public consultation with a view, inter alia, to permit the calculation of the most accurate security factor.
