# Commission Implementing Decision (EU) 2019/2031 of 12 November 2019 establishing best available techniques (BAT) conclusions for the food, drink and milk industries, under Directive 2010/75/EU of the European Parliament and of the Council (notified under document C(2019) 7989) (Text with EEA relevance), Division 1.2: Monitoring

Extent: E+W+S+N.I.

BAT 3. For relevant emissions to water as identified by the inventory of waste water streams (see BAT 2), BAT is to monitor key process parameters (e.g. continuous monitoring of waste water flow, pH and temperature) at key locations (e.g. at the inlet and/or outlet of the pre-treatment, at the inlet to the final treatment, at the point where the emission leaves the installation).
BAT 4. 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.
The monitoring only applies when the substance concerned is identified as relevant in the waste water stream based on the inventory mentioned in BAT 2.
The monitoring only applies in the case of a direct discharge to a receiving water body.
TOC monitoring and COD monitoring are alternatives. TOC monitoring is the preferred option because it does not rely on the use of very toxic compounds.
If the emission levels are proven to be sufficiently stable, a lower monitoring frequency can be adopted but in any case at least once every month.

BAT 5. BAT is to monitor channelled emissions to air with at least the frequency given below and in accordance with EN standards.
The measurements are carried out at the highest expected emission state under normal operating conditions.
If the emission levels are proven to be sufficiently stable, a lower monitoring frequency can be adopted but in any case at least once every year.
The measurement is carried out during a campaign of two days.
The monitoring only applies when a thermal oxidiser is used.
