Express 15. the first sentence of the following paragraph: "the operational monitoring of surface water in their chosen biological, hidromorfoloģisko and physico-chemical quality parameters that most affects a specific load, as well as tested priority substances and other contaminants, which ūdensobjekt in the municipality concerned significant quantities." 2. Express 18.1, 18.2, 18.3, 18.4 and 18.5 points by the following: 18.1 priority substances "and the monitoring of dangerous substances into surface waters can be replaced with alternative monitoring these substances in the aquatic environment or biota of taksono matrix, which the legislative act on surface and groundwater quality, not necessarily the quality of the environment for the application of the regulations, if the following requirements are met: 1. the waters of 18.1 for the assessment of the chemical legislation on water protection is definitely relevant priority substances and of dangerous substances in the environment quality regulations alternative matrix or biota taxon; 2. this rule 18.1 18.1 1 of the environmental quality referred to in the regulations ensure aquatic ecosystems the equivalent level of protection as the laws for the protection of waters down the relevant environmental quality standards for surface waters for the assessment of the chemical; 18.1 3. specific method of testing the substance chosen alternative matrix or taxon biota complies with this provision in annex 2 of the above requirements for waters in the chemical testing methods used for monitoring the performance characteristics. If no matrix or taxon has no available testing method performance characteristics comply with those provisions in annex 2 requirements, monitoring is carried out using the best available analytical methods, which do not entail excessive costs. While the substance of alternative testing method or taxon matrix to ensure at least as well as the method of performance characteristics that are available for testing the matrix that the legislative act on surface and ground water quality, certain environmental quality regulations. 18.2 making it the priority and the monitoring of hazardous substances, which ūdensobjekt the assessment of the chemical used in the laws for the protection of aquatic biota or sediment laid down environmental quality regulations, the respective matrices in samples taken at least once a year. 18.3 replacing and priority hazardous substances into surface waters monitoring this provision in paragraph 18.1 alternative monitoring centre, the European Commission provides the information set out in the Act, regulations for the river basin district management plans and programmes of measures. 18.4 special priority substances referred to in the provisions of annex 5, 21, 28, 30, 35, 37, 43 and 44, in view of the persistence of these substances and a wide spread of surface water environment monitoring ūdensobjekt for the assessment of the chemical can be performed less frequently than required by this rule 18.2 points, every three years, reducing the number of monitoring stations or sampling frequency, if: 1. the above findings 18.4 monitoring results show that the presence of these substances in the environment of the waters has decreased and reached statistically reliable and stable base concentration of these substances; 2. such monitoring is 18.4 ensure collection of representative data for further changes in the concentration of these substances for analysis. 18.5 basis monitoring the waters in these rules referred to in paragraph 3 according to competency institutions assess the priority substances and concentrations of hazardous substances in sediments or biota changes that its physico-chemical characteristics of sediments or biota to accumulate. Long-term trend analysis of concentrations at least 3 of these regulations. 2, 5, 6, 7, 12, 15, 16, 17, 18, 20, 21, 26, 28, 30, 34, 35, 36, 37, 43 and 44. the substances referred to in paragraph 1. " 3. To supplement the provisions and paragraph 18.7 18.6 as follows: "to ensure data reliable 18.6 for the long-term changes of the concentration trend analysis, sediment or biota samples for monitoring of this rule 18.5 above requirements take three years. 18.7 design of this Centre, the provisions referred to in paragraph 2 waters monitoring program based on expert assessment of the priority substances and concentrations of hazardous substances of natural and anthropogenic variation and seasonal fluctuation affects, may determine a different sampling frequency than specified in this provision, and 18.6 18.4 18.2 points. " 4. the title of Chapter VI to express the following: "VI. Closing questions". 5. Supplement with 43 points as follows: "43. Center according to paragraph 2, this provision up to 2018-December 22, develop and submit to the European Commission for additional monitoring programme and the provisional programme of measures for substances referred to in annex 3 of these rules 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44 and 45 in.. The substances listed in the final program of measures, consistent with the laws of the river basin district management plans and programmes of measures developed to 2021 22 December and commenced its implementation as soon as possible, but not later than 22 December 2024.
