PART 2 RIVER BASIN MANAGEMENT PLANNING Setting of environmental objectives 3 1 The objectives set under section 9(1)(a)(i) (environmental objectives) of the Act must, subject to the application of regulations 5 to 10 and 17 — a for surface water— i prevent deterioration of the status of each body of surface water; ii protect, enhance and restore each body of surface water (other than an artificial or heavily modified body of surface water) with the aim of achieving good surface water status by 22nd December 2015; iii protect and enhance each artificial or heavily modified body of surface water with the aim of achieving good ecological potential and good surface water chemical status by 22nd December 2015; and iv aim to progressively reduce pollution from priority substances and aim to cease or phase out emissions, discharges and losses of priority hazardous substances; b for groundwater— i prevent the deterioration of the status of each body of groundwater; ii prevent or limit the input of pollutants into groundwater ; iii enhance and restore each body of groundwater, and ensure a balance between abstraction and recharge of groundwater, with the aim of achieving good groundwater status by 22nd December 2015; and iv reverse any significant and sustained upward trend in the concentration of any pollutant resulting from the impact of human activity in order to progressively reduce pollution of groundwater; and c in addition, for each area and body of water falling within section 7(4) (protected areas) of the Act, achieve compliance with any standards and objectives required by or under any assimilated law described in that section by 22nd December 2015, unless otherwise specified in the assimilated law by virtue of which the area or body of water is protected. 2 Where two or more of the objectives set pursuant to paragraph (1) apply to the same body of water, to the extent that any of those objectives conflict, the most stringent is to apply. Designation as artificial or heavily modified bodies of surface water 4 1 SEPA may designate a body of surface water as artificial or heavily modified when— a the changes to the hydromorphological characteristics of the body of surface water, which would be necessary for achieving good ecological status, would have significant adverse effects on— i the wider environment; ii navigation, including port facilities, or recreation; iii activities for the purposes of which water is stored, such as drinking water supply, power generation or irrigation; iv water regulation, flood protection, land drainage; or v other equally important sustainable human development activities; and b the beneficial objectives served by the artificial or modified characteristics of the body of surface water cannot, for reasons of technical feasibility or disproportionate costs, be achieved by other means which are a significantly better environmental option. 2 Where SEPA designates a body of surface water as artificial or heavily modified, it must— a mention the designation, and the reasons for it, in the river basin management plan for the river basin district within which that body is located (or the next update of it); and b review the designation when reviewing and updating the river basin management plan. Environmental objectives: phased achievement 5 The deadline by which an environmental objective set pursuant to regulation 3(1) must be achieved may be extended for the purposes of the phased achievement of the environmental objectives for a body of water (including the objectives for areas falling within section 7(4)(d) (areas designated in respect of water status) of the Act for the protection of habitats or species), if the following conditions are met— a no further deterioration occurs in the status of the affected body of water; b SEPA determines that all necessary improvements in the status of the body of water cannot reasonably be achieved within the timescales set out in regulation 3(1) for at least one of the following reasons— i the scale of improvements required can only be achieved in phases exceeding the timescale, for reasons of technical feasibility; ii completing the improvements within the timescale would be disproportionately expensive; iii natural conditions do not allow timely improvement in the status of the body of water; c extensions are limited to a maximum of two updates of the first river basin management plan (except in cases where the natural conditions are such that the environmental objectives cannot be achieved within that period); d the river basin management plan (or the next update of it) sets out— i the extension of the deadline, and explains the reasons for it; ii a summary of the measures to be applied to achieve the environmental objectives set pursuant to regulation 3(1) which are envisaged as necessary to bring the body of water progressively to the required status by the extended deadline; and iii the reasons for any significant delay in making these measures operational, and the expected timetable for their implementation; and e a review of the implementation of the measures referred to in paragraph (d) and a summary of any additional measures is included in updates of the river basin management plan. Environmental objectives: human activity or natural condition 6 Less stringent environmental objectives may be set under section 9(1)(a)(i) of the Act for a specific body of water instead of those required pursuant to regulation 3(1) when that body of water is so affected by human activity or its natural condition is such that the achievement of the environmental objectives required pursuant to regulation 3(1) would be infeasible or disproportionately expensive, and the following conditions are met— a the environmental and socio-economic needs served by such human activity cannot be achieved by other means which are a significantly better environmental option not entailing disproportionate costs; b where the specific body of water is a body of surface water, the highest ecological and chemical status possible is achieved, given impacts that could not reasonably have been avoided due to the nature of the human activity or pollution; c where the specific body of water is a body of groundwater, the least possible changes to good groundwater status, given impacts that could not reasonably have been avoided due to the nature of the human activity or pollution; d no further deterioration occurs in the status of the affected body of water; and e the establishment of less stringent environmental objectives, and the reasons for it, are set out in the river basin management plan (or the next update of it) and those objectives are reviewed every 6 years. Environmental objectives: natural cause or force majeure 7 For the purposes of these Regulations and Part 1 of the Act (in particular section 9(7)(a) (environmental objectives required to comply with Article 4 and 7 of the Water Framework Directive)), a temporary deterioration in the status of a body of water is not a breach of the environmental objectives set pursuant to regulation 3(1) if the deterioration is the result of circumstances of natural cause or force majeure which are exceptional or could not reasonably have been foreseen, or the result of circumstances due to accidents which could not reasonably have been foreseen, and the following conditions are met— a all practicable steps are taken— i to prevent further deterioration in the status of the body of water; and ii so as not to compromise the achievement of the environmental objectives for any body of water not affected by the circumstances; b the conditions under which circumstances that are exceptional or that could not reasonably have been foreseen may be declared, including the adoption of the appropriate factors, are stated in the river basin management plan (or the next update of it); c the measures to be taken under such exceptional circumstances are included in the programme of measures to be applied to the body of water and will not compromise the recovery of the quality of that body of water once the circumstances are over; d the effects of the circumstances that are exceptional or that could not reasonably have been foreseen are reviewed annually and, subject to the reasons set out in regulation 5(b) all practicable measures are taken with the aim of restoring the body of water to its status prior to the effects of the circumstances as soon as reasonably practicable; and e a summary of the effects of the circumstances and of such measures taken or to be taken in accordance with paragraphs (a) and (d) are included in the next update of the river basin management plan. Environmental objectives: modifications to physical characteristics 8 For the purposes of these Regulations and Part 1 of the Act (in particular section 9(7)(a)), a failure to achieve good groundwater status, good ecological status or, where relevant, good ecological potential, or to prevent deterioration in the status of a body of surface water or a body of groundwater is not a breach of the environmental objectives set pursuant to regulation 3(1) if the failure is the result of new modifications to the physical characteristics of the body of surface water or alterations to the level of the body of groundwater, and the following conditions are met— a all practicable steps are taken to mitigate the adverse impact on the status of the body of water; b the reasons for the modifications or alterations are of overriding public interest and/or the benefits to the environment and to society of achieving the environmental objectives are outweighed by the benefits of the new modifications or alterations to human health, to the maintenance of human safety, or to sustainable development; c the beneficial objectives served by the modifications or alterations of the water body cannot for reasons of technical feasibility or disproportionate costs, be achieved by other means, which are a significantly better environmental option; and d the reasons for the modifications or alterations are set out and explained in the river basin management plan (or the next update of it) and the environmental objectives are reviewed every 6 years. Environmental objectives: sustainable human development activities 9 For the purposes of these Regulations and Part 1 of the Act (in particular section 9(7)(a)), a failure to prevent deterioration from high status to good status of a body of surface water is not a breach of the environmental objectives set pursuant to regulation 3(1) if the failure is the result of new sustainable human development activities, and the following conditions are met— a all practicable steps are taken to mitigate the adverse impact on the status of the body of water; b the activities are of overriding public interest and/or the benefits to the environment and to society of achieving the environmental objectives are outweighed by the benefits of the activities to human health, to the maintenance of human safety, or to sustainable development; c the beneficial objectives served by those activities cannot for reasons of technical feasibility or disproportionate costs, be achieved by other means, which are a significantly better environmental option; and d the nature of the activities are set out and explained in the river basin management plan (or the next update of it) and the environmental objectives are reviewed every 6 years. Environmental objectives: application of regulations 4 to 9 10 Regulations 4 to 9 must not be applied in a way that— a permanently excludes or compromises the achievement of the environmental objectives set in relation to any other body of water within the same river basin district; or b is inconsistent with the implementation of any assimilated law relating to the environment . Waters used for the abstraction of drinking water 11 For each body of water identified under section 6(1) (bodies of water used for the abstraction of drinking water) of the Act, the programme of measures for the river basin district within which the body of water is located must ensure the necessary protection of the body of water with the aim of avoiding deterioration in the quality of that body of water in order to reduce the level of purification treatment required in the production of drinking water. Content of monitoring programme 12 1 Each monitoring programme prepared under section 8(2) (monitoring programme) of the Act must— a enable a coherent and comprehensive overview of the status of the water environment within each river basin district; b for surface water— i cover the volume and level or rate of flow to the extent relevant to ecological status (or, where relevant, ecological potential) and chemical status; ii cover the ecological status (or, in the case of an artificial or heavily modified body of water, ecological potential) and chemical status; and iii enable the classification of each body of surface water in accordance with Annex V to the Water Framework Directive ; c for groundwater— i cover monitoring of the chemical and quantitative status; ii enable a reliable assessment of the groundwater status, including assessment of the available groundwater resource; and iii enable the detection of any long-term anthropogenically induced upward trend in the concentration of any pollutant; and d for protected areas (within the meaning of section 7(3) (protected areas) of the Act)— i cover any supplementary monitoring required by the legislation under which the area is protected; and ii provide for the monitoring of any body of water identified under section 6(1) of the Act which provides more than 100 m 3 per day of drinking water intended for human consumption. 2 SEPA must ensure that monitoring for purposes of any programme prepared under section 8(2) of the Act is carried out in accordance with Annex V to the Water Framework Directive. Preparation of programme of measures 13 1 Each programme of measures must include the following measures (as further specified and qualified by Article 11(3) of the Water Framework Directive) — a measures required under assimilated law for the protection of water;

j a prohibition of direct discharges of pollutants into groundwater, except that the reinjection into the same aquifer of water used for geothermal purposes may be authorised and the following discharges may also be authorised (with conditions)— i injection of water containing only substances resulting from operations for exploration and extraction of hydrocarbons or mining activities, and injection of water for technical reasons, into geological formations— aa from which hydrocarbons or other substances have been extracted; or bb which, for natural reasons, are permanently unsuitable for other purposes; ii reinjection of pumped groundwater from mines and quarries or associated with the construction or maintenance of civil engineering works; iii injection of natural gas or liquefied petroleum gas for storage purposes into— aa geological formations which, for natural reasons, are permanently unsuitable for other purposes; or bb other geological formations where there is an overriding need for security of gas supply and the injection is such as to prevent any present or future danger of deterioration in the quality of any receiving groundwater; iv injection of carbon dioxide streams for storage purposes into geological formations which, for natural reasons, are permanently unsuitable for other purposes, provided that such injection is made in accordance with the assimilated law which implemented Directive 2009/31/ EC of the European Parliament and of the Council on the geological storage of carbon dioxide ...; v construction, civil engineering and building works and similar activities on or in the ground which come into contact with groundwater; and vi discharges of small quantities of substances for scientific purposes for characterisation, protection or remediation of a body of water limited to the amount strictly necessary for the purposes concerned, provided such discharges do not compromise the achievement of the environmental objectives for that body of groundwater; k measures to eliminate pollution of surface waters by priority substances and to progressively reduce pollution by other substances which would otherwise prevent the achievement of the environmental objectives for each body of surface water; and l any measures required to prevent significant losses of pollutants from technical installations, and to prevent and/or to reduce the impact of accidental pollution incidents for example as a result of floods, including through systems to detect or give warning of such events including, in the case of accidents which could not reasonably have been foreseen, all appropriate measures to reduce the risk to aquatic ecosystems. 2 Each programme must also include, where necessary, any other measures designed and implemented with the aim of achieving the environmental objectives set pursuant to regulation 3(1). 3 Where monitoring or other data indicate that the environmental objectives set pursuant to regulation 3(1) for a body of water are unlikely to be achieved, SEPA must take steps to ensure that— a the causes of the possible failure are investigated; b any relevant permits and authorisations are examined and reviewed as appropriate; c the monitoring programmes are reviewed and adjusted as appropriate; and d any additional measures needed to achieve those objectives (subject to the application of regulations 5 to 10) are included in the programme of measures applying to that body of water. 4 Each measure in a programme of measures to be applied to achieve an environmental objective, must be implemented, so far as may be applicable, by— a the Scottish Ministers in exercising their functions under the relevant enactments; b SEPA in exercising its functions under the relevant enactments; and c each responsible authority in exercising its designated functions. 4A In implementing any measure pursuant to paragraph (4), the Scottish Ministers, SEPA or a responsible authority, as the case may be, must— a ensure that the application of measures taken pursuant to paragraph (1) does not lead directly or indirectly to increased pollution of surface waters; b take all appropriate steps not to increase pollution of marine waters; and c periodically review and, where necessary, update the controls, requirements or measures in paragraph (1)(e) to (i). 5 Each programme of measures, in so far as it comprises measures to achieve an environmental objective, must be reviewed and, if necessary, updated by 22nd December 2015 and every 6 years after that. 6 Where a programme of measures is updated under paragraph (5), any new or revised measure to achieve an environmental objective which is included in the updated programme must be implemented within 3 years of the date on which that measure was added or revised.

PART 3 SPECIFIC MEASURES AGAINST POLLUTION OF WATER Interpretation of Part 3 16 1 In this Part— “biota taxon” means a particular aquatic taxon within the taxonomic rank ‘sub-phylum’, ‘class’ or their equivalent; “ Directive 2009/90/EC ” means Commission Directive 2009/90/EC laying down, pursuant to Directive 2000/60/EC of the European Parliament and of the Council, technical specifications for chemical analysis and monitoring of water status; “EQS” means environmental quality standards or, where the context so requires, environmental quality standard; “existing obligations” means the obligations (on environmental quality standards in the field of water policy) under Directive 2008/105/EC of the European Parliament and of the Council (“the original Directive”) before it was amended by Directive 2013/39/ EU of the European Parliament and of the Council including, in particular, the achievement of good surface water chemical status in relation to the substances and the associated EQS listed in the original Directive; “limit of detection” means the output signal or concentration value above which it can be affirmed, with a stated level of confidence that a sample is different from a blank sample containing no determinand of interest; “limit of quantification” means a stated multiple of the limit of detection at a concentration of the determinand that can reasonably be determined with an acceptable level of accuracy and precision; “matrix” means a compartment of the aquatic environment, namely water, sediment or biota; “Part A” means Part A of Annex I to the Priority Substances Directive (as read with the definitions and notes contained in that Part); “Part B” means Part B of Annex I to the Priority Substances Directive; ... “watch list” means the watch list of substances established under Article 8b(1) and (2) of the Priority Substances Directive. 2 For the purposes of this Part, the limit of quantification may be calculated using an appropriate standard or sample, and may be obtained from the lowest calibration point on the calibration curve, excluding the blank. 3 When interpreting Directive 2009/90/EC for the purposes of this Part, a reference to one or more member States in a provision imposing an obligation, or conferring a discretion, on a member State or member States is to be read as a reference to SEPA. Environmental quality standards for bodies of surface water 17 1 Subject to paragraph (2), SEPA must, for each body of surface water within a river basin district, apply the EQS in Part A in accordance with the requirements in Part B. 2 Without prejudice to existing obligations, SEPA must— a from 22nd December 2015, apply the EQS in Part A for the substances numbered (2), (5), (15), (20), (22), (23) and (28) (in column (1) of the table in that Part) with the aim of achieving good surface water chemical status in relation to those substances by 22nd December 2021 by means of the programme of measures included in the river basin management plan (or an update of it); and b from 22nd December 2018, apply the EQS in Part A for the substances numbered (34) to (45) (in column (1) of the table in that Part) with the aim of achieving good surface water chemical status in relation to those substances by 22nd December 2027 and preventing deterioration in the chemical status of each body of surface water in relation to those substances. 3 The objectives set under section 9(1)(a)(i) of the Act must, subject to the application of regulations 5 to 10 and without prejudice to any other objectives that are required to be set under that section, aim to achieve the obligations in paragraph (2). 4 For the purposes of paragraph (3), references in regulations 5 to 9 to an objective set pursuant to regulation 3(1) are to be construed as an objective set pursuant to paragraph (3). 5 For the purposes of paragraph (2)(b), SEPA must— a by 22nd December 2018, establish a supplementary monitoring programme and a preliminary programme of measures covering those substances; b by 22nd December 2021, establish a full programme of measures covering those substances (“the full programme”); and c as soon as possible after 22nd December 2021, and not later than 22nd December 2024, implement and make fully operational the full programme. 6 SEPA must apply— a the biota EQS in Part A for the substances numbered (5), (15), (16), (17), (21), (28), (34), (35), (37), (43) and (44) (in column (1) of the table in that Part); and b the water EQS in Part A for the other substances numbered (in that column). 7 SEPA may in relation to one or more categories of surface water, apply— a an EQS for a matrix other than that specified in paragraph (6); or b where relevant, an EQS for a biota taxon other than that specified in Part A. 8 Where SEPA makes use of the option in paragraph (7), it must— a apply the EQS for the substances in question; or b if there is no EQS for the matrix or biota taxon in question, establish an EQS for that matrix or biota taxon that offers at least the same level of protection as the corresponding EQS for those substances in relation to other matrix and biota taxon. 9 SEPA may use the option in paragraph (7) only where— a the method of analysis used for the chosen matrix or biota taxon fulfils the minimum performance criteria in Article 4 of Directive 2009/90/EC ; or b if the method does not fulfil those criteria for any matrix, SEPA ensures— i that the method of analysis performs at least as well as that available for the matrix specified in paragraph (6) for the relevant substance; and ii that monitoring is carried out using best available techniques not entailing excessive costs. 10 Where a biota or sediment EQS for a substance in Part A is being applied and a potential risk to, or via, the water environment from acute exposure to the substance has been identified as a result of measured or estimated environmental concentrations or emissions of that substance, SEPA must— a additionally apply any MAC-EQS in Part A for that substance; and b carry out monitoring in relevant bodies of surface water for that substance. 11 Any measured result for the substance being monitored must not be considered by SEPA for the purposes of assessing the chemical status of a body of surface water where— a pursuant to Article 5 of Directive 2009/90/EC , the calculated mean value of a measurement, when carried out using the best available technique not entailing excessive costs, is referred to as ‘less than limit of quantification’; and b the limit of quantification of that technique is above the EQS for the substance. 12 For substances for which an EQS for sediment or biota is applied, SEPA must, subject to paragraph (13), monitor the substance in the relevant matrix at least once every year, unless technical knowledge and expert judgment justify a different interval. 13 SEPA may monitor the substances numbered (5), (21), (28), (30), (35), (37), (43) and (44) (in column (1) of the table in Part A) less intensively than is required by paragraph (12) and Annex V to the Water Framework Directive provided that the monitoring— a is representative and a statistically robust baseline is available regarding the presence of those substances in the aquatic environment; and b takes place for each of the substances at least once every 3 years (unless technical knowledge and expert judgment justify a different interval). 14 SEPA must include the following information in the river basin management plan (or the next update of it)— a a table presenting the limits of quantification of the methods of analysis applied, and information on the performance of those methods in relation to the minimum performance criteria in Article 4 of Directive 2009/90/EC ; b for the substances for which the option in paragraph (7) is used— i the reasons and basis for using that option; ii where relevant, the alternative EQS established, evidence that those EQS would offer at least the same level of protection as the EQS in Part A, including the data and methodology used to derive the EQS, and the categories of surface water to which they would apply;

b take measures aimed at ensuring, subject to Article 4 of the Water Framework Directive, that such concentrations do not significantly increase in sediment or relevant biota; c determine the frequency of monitoring in sediment and biota so as to provide sufficient data for reliable long-term trend analysis of each priority substance; and d ensure that monitoring for each priority substance takes place at least once every 3 years, unless technical knowledge and expert judgment justify a different interval. Designation of mixing zones 18 1 SEPA may designate a mixing zone adjacent to any point of discharge to the water environment which is a controlled activity. 2 SEPA must ensure that the extent of any such zone is— a restricted to the proximity of the point of discharge; and b proportionate, having regard to the concentrations of pollutants at the point of discharge and to the conditions on emissions of pollutants contained in any prior authorisation. 3 Where SEPA designates a mixing zone, concentrations of one or more substances listed in Part A of Annex I to the Priority Substances Directive may exceed the relevant environmental quality standards within that zone, provided that this does not affect the compliance of the rest of the body of surface water with those standards. 4 The river basin management plan (or the next update of it) for a river basin district within which a mixing zone (or any part of a mixing zone) has been designated must include a description of— a the approaches and methodologies applied to define such zones; and b measures taken with a view to reducing the extent of the mixing zones in the future. 5 In paragraph (1), “ controlled activity ” has the meaning given in regulation 2(1) of the Water Environment (Controlled Activities) (Scotland) Regulations 2011 . Register of emissions, discharges and losses 19 1 For each river basin district, SEPA must maintain a register (including maps, if available) of emissions, discharges and losses of all priority substances and any pollutant listed in Part A of Annex I to the Priority Substances Directive, including their concentration in sediment and biota, as appropriate. 2 The reference period for the estimation of pollutant values to be entered in the register must be one year between 2008 and 2010, except that for priority substances and any pollutant covered by Council Directive 91/414/ EEC concerning the placing of plant protection products on the market, the entries may be calculated as the average of the years 2008, 2009 and 2010. 3 SEPA must update the register as part of (or, so far as it applies to an area of Scotland which is outside a river basin district, in conjunction with) each review under section 5(3) (review of characterisations) of the Act. 4 The reference period which must be applied for the establishment of values in the updated register is the year before that review is to be completed, except that for priority substances and any pollutant covered by Council Directive 91/414/EEC , the entries may be calculated as the average of the 3 years before the completion of that review. 5 SEPA must publish the updated register (except in so far as it applies to an area of Scotland which is outside a river basin district) in each update of the river basin management plan. 6 For the purposes of paragraph (1) only— “ river basin district ” includes— the part of the Northumbria River Basin District which is in Scotland; and the part of the Solway Tweed River Basin District which is in Scotland; “ the Northumbria River Basin District ” means the area identified by regulation 3(1) of the Water Environment (Water Framework Directive) (Northumbria River Basin District) Regulations 2003 ; and “ the Solway Tweed River Basin District ” means the area identified by regulation 3(1) of the Water Environment (Water Framework Directive) (Solway Tweed River Basin District) Regulations 2004 . Coordination 19A . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Watch list 19B 1 SEPA must monitor each substance in the watch list at selected representative monitoring stations for a period of at least 12 months (“the monitoring period”). 2 For each substance in the watch list as first established by Commission Implementing Decision ( EU ) 2015/495, the monitoring period must begin on 14th September 2015. 3 For any substance added to the watch list after it was first established, the monitoring period must begin within 6 months of the date on which the substance was added to the list. 4 SEPA must select at least two representative monitoring stations. 5 In selecting representative monitoring stations, and the monitoring frequency and timing for each substance, SEPA must— a take into account the use patterns and possible occurrence of the substance; and b ensure that monitoring is carried out at each station at least once per year. 6 SEPA may decide not to monitor a substance under paragraphs (1) to (5) if— a it has sufficient, comparable, representative and recent monitoring data for the substance from existing monitoring programmes or studies; and b the monitoring was carried out in accordance with a methodology that satisfies any guidelines developed under Article 8b(5) of the Priority Substances Directive. PART 4 SPECIFIC MEASURES TO PREVENT AND CONTROL POLLUTION OF GROUNDWATER Interpretation of Part 4 20 1 In this Part— “ background level ” means the concentration of a substance or the value of an indicator in a body of groundwater corresponding to no, or only very minor, anthropogenic alterations to undisturbed conditions; “ baseline level ” means the average value measured at least during the reference years 2007 and 2008 on the basis of monitoring in accordance with a programme prepared under section 8(2) (monitoring) of the Act or, in the case of substances identified after these reference years, during the first period for which a representative period of monitoring data is available; ... “ groundwater quality standard ” means an environmental quality standard expressed as the concentration of a particular pollutant, group of pollutants or indicator of pollution in groundwater, which should not be exceeded in order to protect human health and the environment; “ input of pollutants into groundwater ” means the direct or indirect introduction of pollutants into groundwater as a result of human activity; “ significant and sustained upward trend ” means any statistically and environmentally significant increase of concentration of a pollutant, group of pollutants, or indicator of pollution in groundwater for which trend reversal is identified as being necessary in accordance with regulation 23; and “ threshold value ” means a groundwater quality standard established under regulation 21(2). Criteria for assessing groundwater chemical status 21 1 For the purposes of assessing the chemical status of each body of groundwater (or group of such bodies) under section 8 (monitoring) of the Act, SEPA must use the following criteria— a groundwater quality standards in Annex I to the Groundwater Directive; and b threshold values which the Scottish Ministers direct (in exercise of powers conferred by the Act or any other enactment) SEPA to apply for those purposes. 2 Threshold values must be established in accordance with Annex II to the Groundwater Directive, based on the protection of the body of groundwater and having particular regard to its impact on, and interrelationship with, associated surface waters and directly dependent terrestrial ecosystems and wetlands and take into account human toxicology and ecotoxicology knowledge. 3 Where new information indicates that, to protect human health and the environment, a new threshold value should be applied or a threshold value being applied should be revised, SEPA must submit to the Scottish Ministers proposals for a new or revised threshold value to be applied. 4 The river basin management plan (or the next update of it) must include— a the threshold values which apply for the purposes of paragraph (1); b any changes to those threshold values since the plan was last approved; and c ...the information set out in Part C of Annex II to the Groundwater Directive. Procedure for assessing groundwater chemical status 22 1 SEPA must use the procedure in paragraph (2) to assess the chemical status of a body of groundwater but, in carrying out this procedure, a body of groundwater may, if appropriate, be grouped with other such bodies in accordance with Annex V to the Water Framework Directive. 2 The body of groundwater (or group of such bodies) must be considered to be of good chemical status when— a relevant monitoring shows that the conditions set out in section 2.3.2 (good groundwater chemical status) of Annex V to the Water Framework Directive are being met; b the values for the groundwater quality standards in Annex I to the Groundwater Directive and the threshold values which apply for the purposes of regulation 21(1)(b) are not exceeded at any monitoring point in the body of groundwater (or group of such bodies); or c the value for any such groundwater quality standard or any such threshold value is exceeded at one or more monitoring points but an appropriate investigation in accordance with Annex III to the Groundwater Directive confirms that— i on the basis of the assessment referred to in paragraph 3 of Annex III to the Groundwater Directive, the concentrations of pollutants exceeding the groundwater quality standard or threshold value is not considered to present a significant environmental risk, taking into account, where appropriate, the extent of the body of groundwater (or group of such bodies) which is affected; ii the other conditions for good groundwater chemical status in section 2.3.2 in Annex V to the Water Framework Directive are being met in accordance with paragraph 4 of Annex III to the Groundwater Directive; iii for any body of groundwater identified in accordance with section 6 (water used for abstraction) of the Act, the requirements of regulation 11 are being met in accordance with paragraph 4 of Annex III to the Groundwater Directive; and iv the ability of the body of groundwater (or, as the case may be, each such body in the group) to support human uses has not been significantly impaired by pollution. 3 SEPA must publish a summary of the assessment of groundwater chemical status in the river basin management plan (or the next update of it), including an explanation as to the manner in which exceedances of groundwater quality standards or threshold values at individual monitoring points have been taken into account in the final assessment. 4 If a body of groundwater is classified as being of good chemical status in accordance with paragraph (2)(c), SEPA must, in exercising its functions under the relevant enactments, take such action as may be necessary to protect aquatic ecosystems, terrestrial ecosystems and human uses of groundwater dependent on the part of the body of groundwater represented by the monitoring point or points at which the value for a groundwater quality standard or the threshold value has been exceeded. Identification of significant and sustained upward trends and the definition of starting points for trend reversals 23 1 SEPA must, in accordance with Annex IV to the Groundwater Directive, for any body of groundwater (or, as the case may be, group of such bodies) that it has characterised as being at risk of failing to meet the environmental objectives set pursuant to regulation 3(1)— a identify any significant and sustained upward trend in the concentration of a pollutant, a group of pollutants or any indicator of pollution; and b determine the starting point for reversing that trend. 2 SEPA must, in accordance with Part B of Annex IV to the Groundwater Directive, take steps to ensure that each programme of measures will reverse trends which present a significant risk of harm to the quality of aquatic ecosystems or terrestrial ecosystems, to human health, or to actual or potential legitimate uses of the water environment, in order progressively to reduce pollution and prevent deterioration of groundwater. 3 SEPA must determine the starting point for trend reversal as a percentage of the level of the groundwater quality standards and threshold values, on the basis of the identified trend and the associated environmental risk, in accordance with paragraph 1 in Part B of Annex IV to the Groundwater Directive. 4 Where necessary to assess the impact of existing plumes of pollution in a body of groundwater that may threaten the achievement of the environmental objectives set pursuant to regulation 3(1) including, in particular, plumes resulting from point sources and contaminated land, SEPA must carry out additional trend assessments for identified pollutants to verify that plumes from contaminated sites— a do not expand; b do not deteriorate the chemical status of the body of groundwater (or the group of such bodies); and c do not present a risk for human health and the environment. 5 The river basin management plan (or the next update of it) must include a summary of— a the way in which the trend assessment from individual monitoring points within the body of groundwater (or group of such bodies) has contributed to identifying, in accordance with section 2.5 (presentation of groundwater status) of Annex V to the Water Framework Directive, that the body (or group of such bodies) is subject to a significant and sustained upward trend in concentration of any pollutant or a reversal of that trend; b the reasons for the starting points determined pursuant to paragraph (3); and c the results of any assessment under paragraph (4). Measures to prevent or limit inputs of pollutants into groundwater 24 1 Each programme of measures must include — a for any hazardous substance, all measures necessary to prevent the input of the substance into groundwater; and b for any other pollutant, considered to present an existing or potential risk of pollution, all measures necessary to limit inputs of the pollutant into groundwater so as to ensure that such inputs do not cause deterioration or significant and sustained upward trends in the concentrations of pollutants in groundwater. 2 For the purposes of paragraph (1), inputs of pollutants from diffuse sources of pollution having an impact on the groundwater chemical status must be taken into account whenever technically possible. 3 Without prejudice to any more stringent requirement in assimilated law , paragraph (1) does not apply to the input of pollutants that are— a the result of direct discharges authorised in accordance with regulation 13(1)(j); b considered by SEPA to be of a quantity and concentration so small as to obviate any present or future danger of deterioration in the quality of the receiving groundwater; c the consequences of accidents or exceptional circumstances of natural cause that could not reasonably have been foreseen, avoided or mitigated; d the result of artificial recharge or augmentation of any body of groundwater authorised in accordance with regulation 13(1)(f); e in the view of SEPA incapable, for technical reasons, of being prevented or limited without using— i measures that would increase risks to human health or to the quality of the environment as a whole; or ii disproportionately costly measures to remove quantities of pollutants from, or otherwise control their percolation in, contaminated ground or subsoil; or f the result of interventions in surface waters for the purposes, amongst others, of mitigating the effects of floods and droughts, and for the management of waters and waterways, including at international level, provided that— i the interventions are authorised for that purpose; and ii the inputs do not compromise the achievement of the environmental objectives set pursuant to regulation 3(1) for each body of water concerned, provided that efficient monitoring of each body of groundwater concerned, in accordance with section 2.4.2 (surveillance monitoring) of Annex V to the Water Framework Directive, or other appropriate monitoring, is being carried out.
