# Commission Implementing Decision (EU) 2018/1147 of 10 August 2018 establishing best available techniques (BAT) conclusions for waste treatment, under Directive 2010/75/EU of the European Parliament and of the Council (notified under document C(2018) 5070) (Text with EEA relevance), Division 1.2: Monitoring Extent: E+W+S+N.I. BAT 6. For relevant emissions to water as identified by the inventory of waste water streams (see BAT 3), BAT is to monitor key process parameters (e.g. waste water flow, pH, temperature, conductivity, BOD) at key locations (e.g. at the inlet and/or outlet of the pretreatment, at the inlet to the final treatment, at the point where the emission leaves the installation). BAT 7. BAT is to monitor emissions to water with at least the frequency given below, and in accordance with EN standards. If EN standards are not available, BAT is to use ISO, national or other international standards that ensure the provision of data of an equivalent scientific quality. Monitoring frequencies may be reduced if the emission levels are proven to be sufficiently stable. In the case of batch discharge less frequent than the minimum monitoring frequency, monitoring is carried out once per batch. The monitoring only applies when the substance concerned is identified as relevant in the waste water inventory mentioned in BAT 3. In the case of an indirect discharge to a receiving water body, the monitoring frequency may be reduced if the downstream waste water treatment plant abates the pollutants concerned. Either TOC or COD is monitored. TOC is the preferred option, because its monitoring does not rely on the use of very toxic compounds. The monitoring applies only in the case of a direct discharge to a receiving water body.

BAT is to monitor channelled emissions to air with at least the frequency given below, and in accordance with EN standards. If EN standards are not available, BAT is to use ISO, national or other international standards that ensure the provision of data of an equivalent scientific quality. Monitoring frequencies may be reduced if the emission levels are proven to be sufficiently stable. The monitoring only applies when the substance concerned is identified as relevant in the waste gas stream based on the inventory mentioned in BAT 3. Instead of EN 1948-1, sampling may also be carried out according to CEN/TS 1948-5. The odour concentration may be monitored instead. The monitoring of NH3 and H2S can be used as an alternative to the monitoring of the odour concentration. The monitoring only applies when solvent is used for cleaning the contaminated equipment.

BAT is to monitor diffuse emissions of organic compounds to air from the regeneration of spent solvents, the decontamination of equipment containing POPs with solvents, and the physico-chemical treatment of solvents for the recovery of their calorific value, at least once per year using one or a combination of the techniques given below. Technique Description a Measurement Sniffing methods, optical gas imaging, solar occultation flux or differential absorption. See descriptions in Section 6.2. b Emissions factors Calculation of emissions based on emissions factors, periodically validated (e.g. once every two years) by measurements. c Mass balance Calculation of diffuse emissions using a mass balance considering the solvent input, channelled emissions to air, emissions to water, the solvent in the process output, and process (e.g. distillation) residues. BAT 10. BAT is to periodically monitor odour emissions. BAT 11. BAT is to monitor the annual consumption of water, energy and raw materials as well as the annual generation of residues and waste water, with a frequency of at least once per year. --- Source: https://www.legislation.gov.uk/eudn/2018/1147/annex/division/1/division/1.2 (the official version) Page: https://openlegislation.uk/eu-decision-2018-1147/annex/division-1/division-1.2 Contains public sector information licensed under the Open Government Licence v3.0.
