  "text": "BAT is to monitor emissions and other relevant process parameters, including those indicated below, with the given associated frequency and to monitor emissions 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.\nParameter\nFrequency\nApplicability\na\nMeasurement of water consumption in the two process stages: up to tanning and post-tanning, and recording of production in the same period.\nAt least monthly.\nApplicable to plants carrying out wet processing.\nb\nRecording of the quantities of process chemicals used in each process step and recording of production in the same period.\nAt least yearly.\nGenerally applicable.\nc\nMonitoring of the sulphide concentration and total chromium concentration in the final effluent after treatment for direct discharge to receiving water, by using flow proportional 24-hour composite samples.\nMonitoring of the sulphide concentration and total chromium concentration after chromium precipitation for indirect discharge, by using flow proportional 24-hour composite samples.\nOn a weekly or monthly basis.\nThe monitoring of chromium concentration is applicable to on-site or off-site plants which undertake chromium precipitation.\nWhere economically viable, the monitoring of sulphide concentration is applicable to plants carrying out some part of effluent treatment on site or off site for treating waste waters from tanneries.\nd\nMonitoring of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and ammoniacal nitrogen after on-site or off-site effluent treatment for direct discharges to receiving water, by using flow-proportional 24-hour composite samples.\nMonitoring of total suspended solids after on-site or off-site effluent treatment for direct discharges to receiving water.\nOn a weekly or monthly basis.\nMore frequent measurements in case process changes are needed.\nApplicable to plants carrying out some part of effluent treatment on-site or off-site for treating waste waters from tanneries.\ne\nMonitoring of halogenated organic compounds after on-site or off-site effluent treatment for direct discharges to receiving water.\nOn a regular basis.\nApplicable to plants where halogenated organic compounds are used in the production process and are susceptible to being released into receiving water.\nf\nMeasurement of pH or redox potential at the liquid outlet of wet scrubbers.\nContinuously.\nApplicable to plants using wet scrubbing to abate hydrogen sulphide or ammonia emissions to the air.\ng\nThe keeping of a solvent inventory on an annual basis, and recording of production in the same period.\nOn an annual basis.\nApplicable to plants carrying out finishing using solvents and using water-borne coatings or similar materials to limit the solvent input.\nh\nMonitoring of volatile organic compound emissions at the outlet of abatement equipment, and recording of production.\nContinuously or periodically.\nApplicable to plants carrying out finishing using solvents and employing abatement.\ni\nIndicative monitoring of the pressure drop across bag filters.\nOn a regular basis.\nApplicable to plants using bag filters to abate particulate matter emissions, where there is a direct discharge to the atmosphere.\nj\nTesting of the capture efficiency of wet scrubbing systems.\nAnnually.\nApplicable to plants using wet scrubbing to abate particulate matter emissions, where there is a direct discharge to the atmosphere.\nk\nRecording of the quantities of process residues sent for recovery, reuse, recycling, and disposal.\nOn a regular basis.\nGenerally applicable.\nl\nRecording of all forms of energy use and of production in the same period.\nOn a regular basis.\nGenerally applicable.",
