DECLARATION
of 18 December 2018
on the procedure for determining the pollution of waste water, for calculating the amount of pollution and for measuring the volume of waste water discharged into surface water
According to Section 89n (5) of Act No. 254 / 2001 Coll., on Water and on the Amendment of Certain Laws (Water Act), as amended by Act No. 113 / 2018 Coll.:
Closer definition of source of pollution
(1) For the purposes of this Decree, the source of pollution shall be the territory of the municipality, or, where appropriate, the territorial separation and sewerage of the municipality, the area of the military escape or the premises of an industrial undertaking or of another object, where they are self-emptied into surface water.
(2) Each source of pollution shall include one or more effluents.
(3) For the purposes of this Decree, a source of uncleaned waste water is also considered as a separate source of pollution.
Procedure for the determination of pollution contained in waste water
(1) The procedure for determining the pollution contained in waste water includes sampling, treatment, storage and transport, analysis of samples and evaluation of the results of such analyses.
(2) The technical requirements for sampling and treatment prior to chemical analysis are set out in Annex 1 to this Regulation.
(3) The pollution indicators and the analytical methods for determining the concentration of pollution which, for the purposes of the charges for discharges of waste water into surface water (hereinafter referred to as "the charge") are mandatory for authorised and control laboratories are set out in Annex 2 to this Decree.
(1) Sampling and analysis of samples shall be carried out by the authorised laboratory in accordance with Article 103a (1) of the Water Act for all sources of pollution subject to the charge.
(2) Samples shall be taken at the place specified by the Water Authority in the permit for discharge of waste water. If the Water Authority has not determined that place, the water authority shall, after consultation with the taxpayer, determine the fee in the protocol.
(1) The minimum sampling frequency and the type of sample taken are determined by the data in the waste water permit for the discharge concerned.
(2) Where the waste water discharge permit does not specify the minimum sampling frequency and the type of sample taken, the procedure laid down in Annex 3 to this Regulation shall be followed, which shall determine the minimum annual sampling frequency of the waste water discharges to determine the concentration of the discharged pollution.
(3) Sampling shall be evenly distributed throughout the calendar year.
(4) In the case of controlled, irregular or impact waste water discharges which are not covered by the authorisation of the water authority, the sampling frequency and the type of sample shall be determined for the purpose of calculating the fee after consultation with the fee manager so that the amount of pollution discharged from the source of pollution is determined as objectively as possible.
(1) The scope of the indicators analysed is determined by the requirements of Annex 2, Part B. 2. of the Water Act.
(2) Sampling shall be documented. The documentation shall be based on the processing of the sampling programme and the standard working procedure for sampling, which shall be drawn up using the statistical methods and technical standards set out in Annex 1 to this Regulation.
(3) Sampling shall be recorded. The records shall also be kept on the results of internal and external checks on compliance with the sampling programme and the standard working procedure for sampling.
(4) Where samples cannot be taken in accordance with Annex 1 to this Decree, the quantity of discharges shall be determined by theoretical calculation.
(1) The administrator of the charge shall determine for which sources of pollution the control laboratory shall carry out the sampling and analysis of the control samples for the purpose of monitoring the monitoring of waste water pollution.
(2) The control laboratory shall inform the taxpayer of the check before it begins. When sampling, the control laboratory shall allow the taxpayer to participate. At his request, he shall forward to him the pre-agreed part of the sample taken, after adjusting the sample referred to in Annex 1 to this Order and exclusively to the samples of the taxpayer.
(3) The control laboratory shall notify the taxpayer of the beginning and end of sampling and draw up a sampling report. The sampling report shall also include a record of the transmission and taking over of the part of the sample taken by the taxpayer, including a specification of the parts of the sample transmitted.
(4) If the taxpayer has doubts as to the representativeness of sampling at a given time, in particular due to the occurrence of a non-standard situation in downstream production, extreme climatic conditions or reported emergency status at a sewage treatment plant, he shall enter this into the sampling report. The control laboratory shall transmit this information at the same time as the results of the analysis of the sample taken to the administrator of the fee. The control laboratory shall transmit the sampling report and the results of the analyses carried out to the taxpayer and the administrator electronically within 20 working days of the end of the collection.
(5) The results of the analysis of waste water according to each pollution indicator shall be given in the analysis report, including the uncertainties of measurements, as indicated in the validation of the method for the authorised laboratory concerned. For the calculation of the average annual concentration and quantity of pollution, the values of the measured uncertainties allowed shall not be taken into account.
(1) Where the control sample taken is analysed at the same time by the authorised laboratory and by the control laboratory and where differences in results exceeding 30% are identified by the taxpayer, which could also affect the level of the fee, the taxpayer may, within 10 working days of receipt of the results, initiate negotiations with the control laboratory in order to clarify and eliminate the causes of the different results. The result of the control laboratory shall be taken as the basis for determining the difference in results.
(2) Where the fee payer has called up the proceedings referred to in paragraph 1, he shall be deemed to agree that the approved laboratory shall provide the control laboratory with all the necessary synergies and transmit the results to it in order to establish the objective state of the matter. The audit laboratory shall inform the administrator of the fee of the outcome of the meeting.
(3) If the control laboratory identifies in its opinion the results of the analysis carried out by it as incorrect, the results of the analysis of this sample shall not be included in the data set for the calculation of the fee for that indicator. If the control laboratory indicates in its opinion the results of its analysis are correct, the result of the control laboratory shall be used for the calculation of the average concentration.
Method for detecting the average concentration of individual waste water pollution
(1) For the determination of the amount of pollution, the results of the analyses of all samples of the authorised laboratory processed under this decree and the results of the analyses of the samples taken by the control laboratory shall be used. Average annual pollution concentration in waste water is collected
(a) for pollution emitted continuously as an arithmetic mean from the results of all sample analyses, if the number is less than 24 in the relevant calendar year;
(b) for pollution discharged continuously, and if the number of samples taken in the relevant calendar year is equal to or greater than 24, by the following procedure:
1. the results of all analyses of samples carried out in the calendar year shall determine the arithmetic mean and calculate the standard deviation sigma n,
2. the arithmetic mean calculated in accordance with point 1 shall be added and subtracted twice the sigma n value and the range of the results of the samples shall be determined,
3. the results of sample analyses exceeding the range of values referred to in point 2 shall be excluded and a new set of sample analyses shall be established; and
4. the arithmetic mean is determined from this set of sample analysis results;
(c) in the case of pollution discharged from campaign production, or in cases of controlled or irregular discharge, by calculation, the method to be determined after consultation with the tax administrator.
(2) Where effluents are discharged from multiple effluents for a single source of pollution, the annual average concentration of effluent from all effluents of the source of pollution shall be calculated for comparison with the fee limits as a proportion of the sum of the amount of pollution discharged from all effluents of the source of pollution and the sum of the volumes of waste water discharged from all effluents of the source of pollution.
(3) If a waste water taxpayer discharges more than one site, the amount of pollution and the volume of waste water discharged from all effluents shall be included for the purposes of calculating the charge.
(4) Multiple drains in one location are individual drains from public sewerage in the municipality or individual drains from industrial production, military escape, construction or equipment.
(1) The fact that the pollution indicators in the waste water listed in Annex 2 to the present Decree and discharged from the source of pollution do not exceed the mass or concentration limits of the charge at the source of the pollution not subject to the charge is demonstrated by the person who releases the waste water into surface water, in particular by monitoring the quantity and quality of waste water discharges at the site and in the manner laid down in the permit for discharge of the waste water.
(2) Where samples with sufficient assurance as provided for in Annex 1 to this Decree cannot be taken, the average concentration of the pollution indicator shall be determined by theoretical calculation.
(1) Where the average concentration of the pollution indicator calculated from the set of results of the control samples over a controlled fee period is more than 30% higher than the concentration claimed by the taxpayer in the charge return, taking as the basis the taxpayer's figure, the concentration determined as the average of the concentration values of the samples taken by the control laboratory shall be used.
(2) The condition for applying the procedure referred to in paragraph 1 is that the minimum size of the set of control analyses carried out in a given case is one quarter of the frequency of samples prescribed by the taxpayer in the discharge permit for the discharge, but not less than 5 samples. The samples of reference samples shall be evenly distributed over the controlled fee period.
(3) The procedure referred to in paragraph 1 shall apply even if the taxpayer does not monitor or monitor the amount of pollution in the waste water discharged.
Implementation of readings of the amount of pollution in the collected water
(1) The annual amount of pollution in the water collected in the relevant pollution indicators shall be calculated as the product of the annual volume of water collected and the average annual concentration of pollution calculated as the arithmetic mean of all samples taken per calendar year.
(2) The average annual concentration of pollution in the water collected shall be demonstrated by the taxpayer:
(a) the results of the monitoring of river basin managers from the control profile of water quality monitoring in water streams, if this profile is near the surface water collection; or
(b) the results of analyses of samples of water taken by authorised laboratories.
(1) Sampling shall be spread evenly throughout the calendar year, except for irregular water sampling, where the time limits for sampling shall be determined by the fee administrator after consultation with the taxpayer.
(2) The minimum sampling frequency for groundwater is 4 free samples in a calendar year and for surface water 12 free samples in a calendar year. Samples shall not be taken at a time when surface or groundwater water quality is affected due to unusual situations, particularly in long-lasting or intense precipitation or snow melting.
(3) Sampling shall be subject to the obligation to keep the documentation referred to in Article 5 (2).
(4) The drawing up of the sampling programme and the standard sampling procedure shall be carried out in accordance with the technical standards for the sampling of surface water and groundwater set out in Annex 1 to this Regulation and accessible to the fee manager.
(5) If the average concentration of pollution in the sampled water indicator subtracted does not exceed twice the limit of determination given for the pollution indicator in the standard for the analytical method used, the amount of pollution shall not be deducted in that pollution indicator.
Measurement of effluent volume
The location, manner and frequency of measurement of the volume of waste water discharged shall be ensured by the taxpayer in accordance with the conditions set out in the waste water discharge permit for the relevant discharge. Where a waste water discharge permit does not specify the location, method and frequency of measurement of the volume of waste water discharged or is not issued for the discharge of a waste water discharge permit, the administrator shall determine the fee for the location, method and frequency of measurement of the waste water discharged after consultation with the taxpayer. The fee manager shall record the outcome of the discussion in the report.
(1) Where a measuring instrument or measuring system is installed, the volume of waste water discharged per calendar year shall be calculated from the data of that measuring instrument or measuring system.
(2) Determined gauges and metering assemblies of the quantity of waste water discharged by a fully filled pipeline are subject to mandatory verification under the legislation governing the consistency and correctness of measuring instruments and measures1).
(3) The accuracy of the measurement system of the quantity of waste water discharged is ensured by the taxpayer to the extent necessary by an assessment of its performance. The performance assessment shall be authorised only by the competent persons referred to in Article 103 (1) of the Water Law (hereinafter referred to as the "measurement group ').
(4) The performance assessment report shall be a document of the performance assessment of the measurement system, annexed to which is the relevant evidence of official measurement carried out for this purpose. A measuring system that meets the technical and metrological requirements for working flow meters and deflected volumes and for assessing their performance shall be considered as functionally fit.
(1) The volume of waste water emitted during the period of failure of the measuring instrument or measuring system shall be derived from the number of hours during which the measuring instrument or measuring system was not in operation and from the average hourly flow over the period from the beginning of the year to the occurrence of the failure. If these data are not available, the volume shall be derived from the data of last year.
(2) The duration of the failure of the measuring instrument or measuring system shall be determined on the basis of the operator's operating record.
(1) Where a measuring instrument or a measuring system complying with the conditions set out in Section 14 is not installed, the volume of waste water shall be determined on the basis of one-off measurements, at least one weekly measurement per calendar year. Measurements shall be authorised only for measuring groups.
(2) The annual volume of waste water discharged shall be calculated as the product of the measured volume over a given period and the number of times per year. For multiple weekly measurements, the arithmetic mean of each measurement shall be used for the calculation.
(3) Disposable measurements shall be made under average flow conditions excluding or immediately after the results measured in long-lasting or intense collisions.
(4) If the volume of effluent effluent is not measured with sufficient credibility or the volume of effluent effluent is not measured by the taxpayer, it shall determine the volume of effluent effluent in agreement with the tax administrator.
(1) The tax administrator shall determine for which sources of pollution the measuring group selected by the tax administrator under Paragraph 103 (2) of the Water Law (hereinafter referred to as the "Control Measurement Group") shall carry out a check on the accuracy of the measurement of the volume of discharges.
(2) The check shall include verification of the accuracy of the measurements by detecting and certifying the volume or flow of waste water discharged.
(3) The control measurement group shall issue a report on the performance check of the measuring system on the basis of official measurements carried out under the legislation governing the consistency and correctness of measuring instruments and measures1).
(4) The results of the check shall be transmitted by the measuring group to the payer and the administrator within 30 days of the completion of the check by means of a data box.
(5) The difference between the fee payer measured in volume for a controlled source of pollution or discharge and the volume measured in the same period of time by the control measurement group for two control measurements shall not exceed 10% of the results of the control measurement group. In the event that this range is exceeded, the product of the effluent volume declared by the taxpayer and the coefficient equal (Q + 100) / 100 shall be used to determine the annual volume of effluent, where Q is the arithmetic mean of the percentage differences in control measurements.
Operational registration formalities
The operational records shall include:
