  "heading": "BAT is to carry out the monitoring of emissions to water, as indicated below, with the indicated frequency and according to 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.",
  "text": "There is a trend to replace COD by TOC for economic and environmental reasons. If TOC is already measured as a key process parameter, there is no need to measure COD; however, a correlation between the two parameters should be established for the specific emission source and waste water treatment step.\nRapid test methods can also be used. The results of rapid tests should be checked regularly (e.g. monthly) against EN standards or, if EN standards are not available, against ISO, national or other international standards which ensure the provision of data of an equivalent scientific quality.\nFor mills operating less than seven days a week, the monitoring frequency for COD and TSS may be reduced to cover the days the mill is in operation or to extend the sampling period to 48 or 72 hours.\nApplicable where EDTA or DTPA (chelating agents) are used in the process.\nNot applicable to plants that provide evidence that no AOX is generated or added via chemical additives and raw materials.\nParameter\nMonitoring frequency\nMonitoring associated with\na\nChemical oxygen demand (COD) or\nTotal organic carbon (TOC)\nDaily\nBAT 19\nBAT 33\nBAT 40\nBAT 45\nBAT 50\nb\nBOD5 or BOD7\nWeekly (once a week)\nc\nTotal suspended solids (TSS)\nDaily\nd\nTotal nitrogen\nWeekly (once a week)\ne\nTotal phosphorus\nWeekly (once a week)\nf\nEDTA, DTPA\nMonthly (once a month)\ng\nAOX (according to EN ISO 9562:2004)\nMonthly (once a month)\nBAT 19: bleached kraft\nOnce every two months\nBAT 33: except TCF and NSSC mills\nBAT 40: except CTMP and CMP mills\nBAT 45\nBAT 50\nh\nRelevant metals (e.g. Zn, Cu, Cd, Pb, Ni)\nOnce a year",
