Article 129 of Law 62/2003, of December 30, of administrative fiscal measures and of social order, proceeded to the modification of the recast text of the Water Law, approved by Royal Legislative Decree 1/2001, of 20 July, in order to incorporate into our legal order Directive 2000 /60/EC of the European Parliament and of the Council of 23 October 2000 establishing a Community framework in the field of water policy.

By virtue of this standard, the corresponding modifications were made in Title III of the recast text of the Water Law, corresponding to the hydrological planning. In particular Articles 40, 41 and 42 were amended and Article 40a was introduced. Modifications were also introduced in other titles that are in close relation to the process of hydrological planning and the achievement of its aims, such as the new definition of the river basin and the introduction of the concept of demarcation. hydrographic (Articles 16 and 16a), changes in the Public Water Administration, with the creation of the Demarcation Water Council and the Committee of Competent Authorities (Articles 35, 36 and 36a), the new objectives environmental, the state of the water bodies and the programmes of measures for the attainment of such objectives (Articles 92 (a), 92 (b) and 92 (c)), the register of protected areas (Article 99a), the express introduction of the principle of recovery of the costs of services related to water management (Article 111a) or the time-limits for the achievement of environmental objectives and for public participation (additional provisions 11th and 12th).

Subsequently, Law 11/2005 of 22 June, amending Law 10/2001 of 5 July, of the National Hydrological Plan, amended the wording of Article 42 (1) (c) of the recast of the Law on Water, establishing a definition of ecological flows and the figure of natural river reserves, and added a new paragraph 5 to Article 46 concerning hydraulic works of general interest.

The legal framework for hydrological planning is completed with the Regulation of the Public Administration of Water and Hydrological Planning, approved by Royal Decree 927/1988, of July 29, in the development of the Titles II and III of the Water Act, and with the Order of 24 September 1992, approving the instructions and complementary technical recommendations for the elaboration of the hydrological plans of inter-community basins.

In compliance with the provisions of Law 29/1985, of 2 August, of Aguas, by Royal Decree 1664/1998, of July 24, the hydrological plans of the North I, North II, North III, Duero, Tajo, Guadiana I, Guadiana were approved II, Guadalquivir, Sur, Segura, Júcar, Ebro and Intra-Community basins of Catalonia. Subsequently, by means of Royal Decree 378/2001 of 6 April, the Hydrological Plan of the Balearic Islands was approved and by Royal Decree 103/2003, of 24 January, the Hydrological Plan of Galicia-Costa was approved.

The normative content of these plans was made public by the Ministerial Orders of 13 August 1999 (plans of the North, Duero, Tajo, Guadiana, Guadalquivir, Segura, Júcar and Ebro) and of 6 September 1999 (plan of the South), and by an Edict of the Board of Waters of the Generality of Catalonia of 16 March 1999 (plan of the Internal Watersheds of Catalonia).

Finally, the planning scheme provided for in Law 29/1985 of 2 August of Aguas was completed with the approval of the National Hydrological Plan by Law 10/2001 of 5 July, which was subsequently amended by the Law 11/2005, of June 22.

In the framework described above, and with the aim of fulfilling the mandates contained in the recast text of the Water Act and Directive 2000 /60/EC, as well as in Decision 2455 /2001/EC, this Regulation is drawn up Hydrological Planning, which replaces, inter alia, the provisions laid down in Title II of the Regulation of the Public Administration of Water and Hydrological Planning. The amendment of this regulation had already been announced in the single additional provision of Royal Decree 1664/1998 of 24 July, with a limited scope if the planning processes in force were compared with the new ones. requirements of Directive 2000 /60/EC to simplify the ongoing process of updating the river basin management plans.

The regulation that is now approved refers exclusively to the hydrological planning and does not develop the aspects related to the Public Administration of Water. This circumstance implies the need to coordinate this regulatory development with the modifications that are made in the regulation of the Public Water Administration, given the special links that logically occur between the two countries. However, the recent enactment of the Royal Decrees 125/2007 of 2 February, for which the territorial scope of the river basin districts is set, and 126/2007, of the same date, should be taken into account. regulate the composition, operation and allocation of the committees of competent authorities of river basin districts with inter-community basins.

The regulatory development occurs in the light of the amendments made to the recast text of the Water Act and those aspects of Directive 2000 /60/EC relating to the hydrological planning which, by its excessive detail, were not incorporated into the transposition that resulted in the modification, in 2003, of the recast text of the Law of Waters. The new Regulation of the Hydrological Planning is part of the existing regulation in order to keep as much coherence as possible with the whole body of law of the right of waters. For this reason, the text responds to the regulatory development mandates contained in the recast text of the Water Law, with the current Regulation of the Public Administration of Water and Planning as basic pillars. Hydrologic and Directive 2000 /60/EC.

Another recent modification of our Ordinance, the one produced by the entry into force of Law 9/2006, of April 28, on the assessment of the effects of certain plans and programs in the environment, must also be dyed for the purpose of coordinating the procedures and actions provided for in this Regulation with those laid down in this Regulation.

As a complement to the above, the accumulated experience in the hydrological planning processes in Spain has to be considered. In this respect, it is important to highlight the importance of the report that the National Water Council issued on the current river basin management plans in 1998 and whose recommendations have been presented in the drafting of the proposed modifications. Similarly, the experience gained from the participation in the Common Strategy for the Implementation of the Water Framework Directive agreed on 24 October 2000 by the Member States, Norway and the European Commission, and in particular, can be cited. their application in the case of the Sugar Pilot Basin.

Finally, and as is logical, the statements in the Spanish case-law regarding the hydrological planning, in particular the judgment of the Constitutional Court 118/1998, of 4 of 4, have been taken into account. June, on positive conflicts of competition promoted by the Government of the Basque Country, by the Executive Council of the Generality of Catalonia and by the Council of Government of the Regional Council of Cantabria in relation to the current Rules of Procedure the Public Administration of Water and Hydrological Planning.

On the other hand, Article 100.2 of the recast text of the Water Act requires the application of the combined approach in the drafting of discharge authorizations. This principle is not provided for in Article 256 of the Regulation of the Public Hydraulic Domain, which is why a new wording is necessary as it is done in Article 51 of the regulation which is adopted.

The project preserves the merchant marine competences provided for in Law 27/1992, of 24 November, of Ports of the State and of the Merchant Navy, attributed to the State by Article 149.1.20. Thus, its fourth final provision enables the Ministry of Public Works to implement and develop its own field, and therefore in matters of maritime safety, navigation, human life at sea and prevention and fight against pollution of the marine environment and maritime transport, in accordance with the provisions of Law 27/1992 of 22 November 1992, of Ports of the State and of the Merchant Navy, as well as of the applicable sectoral legislation.

As for the formal structure of the regulation it has been organized in a preliminary title followed by four other titles. The preliminary title contains the general provisions and deals with the objectives and criteria of the hydrological planning, its territorial scope and the definitions. The title first addresses the substantive aspects of hydrological planning, based on the contents of the hydrological plans. The second title is devoted to the procedural aspects of the preparation and approval of the hydrological plans and the third title to the follow-up and review procedures. Finally, the fourth title is dedicated to the effects of the plans.

The regulation has been reported favourably by the full National Water Council held on October 30, 2006.

In its virtue, on the proposal of the Minister of the Environment, in agreement with the Council of State, and after deliberation of the Council of Ministers at its meeting of July 6, 2007.

Section 2. General Description of the Hydrographic Demarcation

Article 5. Identification and delimitation of surface water masses.

1. The situation and limits of the surface water masses shall be determined in each hydrographic demarcation and a characterization of these masses shall be carried out by classification into categories and types. Different bodies of surface water may be grouped for the purpose of this characterization. The situation and limits of surface water bodies shall be defined by means of a geographical information system.

2. The surface water masses within each river basin district shall be classified in the category of rivers, lakes, transitional waters or coastal waters, specifying in their case whether they are artificial water bodies or water bodies. modified.

Article 6. Ecoreregions and types of surface water bodies.

1. The rivers and lakes will be classified in two ecological regions or ecoregions called the Pyrenees and the Iberian-Macaronesian Region, the first of which corresponds to the Pyrenean area and the second to the rest of Spain. The ecological regions of the transitional and coastal waters will be the Atlantic Ocean and the Mediterranean Sea.

2. For each surface water category, water bodies shall be classified by type. These types can be defined using the ecological regions defined in the previous point and the descriptors set out in the tables in Annex I (system A), or by means of mandatory descriptors and optional descriptors or combinations of descriptors listed in the tables in Annex II (B system).

3. If the second procedure of the previous point is used, at least the same degree of discrimination should be achieved with the first one and the values of the descriptors required to ensure that they can be used must be used. to reliably obtain the specific biological reference conditions of each type.

4. For artificial and highly modified surface water bodies, the classification shall be carried out in accordance with the descriptors corresponding to the category of surface water which most resembles the mass of artificial water or very modified in question.

Article 7. Reference conditions for the types of surface water bodies.

1. For each type of surface water mass, specific hydromorphological and physico-chemical conditions representing the values of the hydromorphological and physicochemical quality indicators for the very good state shall be established. ecological. Specific biological reference conditions shall also be established in such a way that they represent the values of the biological quality indicators for the very good ecological status.

2. The specific conditions of each type may be obtained from measurements made in a reference network for each type of surface water mass, modelling or combination of both methods. Where it is not possible to use any of these methods, expert advice may be sought to establish such conditions. When defining the very good ecological status with regard to concentrations of pollutants, the limits of detection shall be those which can be achieved in accordance with the techniques available at the time the conditions are laid down. type-specific.

3. The reference network for each type of surface water mass shall contain a sufficient number of points in very good condition in order to provide a sufficient level of confidence on the values corresponding to the reference conditions, in a function of the variability of the values of the quality indicators corresponding to a very good ecological status for that type of surface water mass and the modelling techniques applied.

4. The biological reference conditions of the type based on a modelling may be obtained using prediction models or ex-post analysis methods. The methods shall use the available historical, paleontological and other data and provide a sufficient level of confidence in the values corresponding to the reference conditions to ensure that the conditions under this form is consistent and valid for each type of surface water mass.

5. Where it is not possible to set specific reliable reference conditions of the type corresponding to a quality indicator in a type of surface water mass, due to the high degree of natural variability of that indicator, not only as seasonal variations, this indicator may be excluded from the assessment of the ecological status of that type of surface water. In such circumstances, the reasons for this exclusion shall be stated in the hydrological plan.

Article 8. Artificial and highly modified water bodies.

1. A surface water mass may be designated as artificial or highly modified when:

(a) Changes in the hydromorphological characteristics of such a mass that are necessary to achieve good ecological status have considerable negative impacts on the environment, in navigation (including port facilities or recreational activities), in the activities for which water is stored (such as the supply of water intended for the production of water for human consumption, energy production, irrigation or other), in the regulation of water, in the protection against floods, in the defense of the integrity of the coast and in the drainage of land or other equally important sustainable human development activities.

(b) Benefits arising from the artificial or modified characteristics of the water body cannot be reasonably achieved, due to the technical possibilities or disproportionate costs, by other means which constitute a significantly better environmental option.

2. In the case of very modified or artificial surface water bodies, references to the very good ecological status will be interpreted as references to the maximum ecological potential. The values for the maximum ecological potential corresponding to a water mass, as well as the reasons for their consideration as artificial or highly modified, shall be reviewed every six years in the hydrological plan.

Article 9. Identification and delimitation of groundwater bodies.

1. In each river basin district the situation and the limits of the groundwater bodies fully within its territory shall be determined by means of a geographical information system and a characterisation of these bodies shall be carried out. masses.

2. The river basin hydrological plans will make a proposal for groundwater masses shared with other demarcations, which will be taken into consideration in the National Hydrological Plan for its delimitation and characterization, as indicated in Article 67 of this Regulation.

Article 10. Characterization of the groundwater masses.

1. An initial characterisation of all bodies of groundwater will be carried out in order to assess the extent to which these waters could no longer be in line with environmental objectives. Different bodies of groundwater may be grouped for the purpose of this initial characterization.

2. The analysis will use the existing data on hydrology, geology, edaphology and soil use and indicate the location and limits of the groundwater masses, the general characteristics of the suprayacent strata in the the catchment area from which the mass of groundwater and the groundwater bodies from which the surface water or terrestrial ecosystems directly depend are fed to it.

3. Once such initial analysis has been carried out, further characterization of the masses or groups of groundwater bodies that present a risk of not achieving the environmental objectives will be carried out in order to assess the accuracy of the the importance of such a risk and to determine more precisely the measures to be taken.

4. This additional characterisation shall include, where appropriate, information on:

a) The geological characteristics of the aquifer, including the extent and type of geological units.

b) The hydrogeological characteristics of the groundwater mass, including permeability, porosity, and confinement.

c) The characteristics of the surface deposits and land in the catchment area from which the groundwater mass receives its feed, including thickness, porosity, permeability and properties absorbents of the deposits and soils.

d) The characteristics of groundwater stratification within the aquifer.

e) An inventory and description of the associated surface systems, including terrestrial ecosystems and surface water bodies, with which the groundwater mass is dynamically connected, including, where appropriate, their relationship to the spaces included in the protected zone registry.

f) The calculations on the directions and rate of exchange of flows between the groundwater mass and the associated surface systems.

g) Enough data to calculate the average annual global recharge rate over the long term.

h) The characteristics of the chemical composition of groundwater. Typologies may be used for the characterization of groundwater when determining the natural reference levels of these bodies of groundwater. The characteristics that are due to the contributions of human activity shall be specified.

Article 11. Inventory of natural water resources.

1. The inventory of natural water resources shall mean the quantitative estimate, the qualitative description and the temporal distribution of these resources in the river basin district. The inventory shall include water which contributes to the input of rivers and which feeds natural water, surface or underground storage.

2. For the purposes of the inventory, the river basin district may be divided into areas and sub-areas. The division shall be carried out in each case on the basis of hydrographic, administrative, socio-economic, environmental or other criteria which in each case may be considered appropriate.

3. The inventory will contain, as far as possible:

(a) Statistical data showing the evolution of the natural regime of flows and storage throughout the hydrological year.

b) Interrelationships of the variables considered, especially between surface and groundwater, and between precipitation and river inputs or aquifer recharge.

c) The zoning and schematization of natural water resources in the river basin district.

d) Basic characteristics of water quality under natural conditions.

4. The hydrological plan will assess the possible effect of climate change on the natural water resources of the demarcation. To this end, it shall estimate the resources corresponding to the climate scenarios provided for by the Ministry of the Environment, which shall be taken into account in the time horizon referred to in Article 21.4.

Section 3. General Description of Significant Anthropic Uses, Pressures, and Incidents

Article 12. Uses of water.

The hydrological plan shall include a table that classifies the uses referred to therein, distinguishing at least those for the supply of populations, irrigation and agricultural uses, industrial uses for the production of electrical energy, other industrial uses, aquaculture, recreational uses, navigation and water transport.

Article 13. Characterization of water demands.

1. To characterize a demand the following data will be accurate:

a) The annual volume and its temporary distribution.

b) The quality conditions that are required for supply.

c) The level of warranty.

d) The cost and other relevant economic variables.

e) Consumption, that is, the volume that does not return to the hydraulic system.
