The emissions limits and appropriate measures for monitoring emissions to air and water at regulated facilities with an environmental permit for the treatment or transfer of WEEE.

We may set emission limits and monitoring requirements in your permit, based on your emissions inventory and environmental risk assessment.

Where you are required to monitor emissions to comply with the requirements of your environmental permit, you must follow our monitoring guidance when carrying this out.

You must create and maintain an inventory (emissions inventory) of point source emissions to air and water (including emissions to sewer) for your facility.

1. Your facility’s emissions inventory must include information about the relevant characteristics of point source emissions to air, such as the:

2. Monitoring locations must meet MCERTS standards. Monitoring must be carried out using MCERTS qualified accredited methods and MCERTS certified staff. Further guidance can be found in our guidance M1 sampling requirements for stack emissions monitoring.

3. You must carry out emissions monitoring when the plant is operating at or near to full treatment capacity. Information regarding the plant treatment processing rate and air flow rate at the time of monitoring must be recorded and submitted with the monitoring results.

4. You must monitor point source emissions to air from your treatment plant for the following substances using the monitoring standards stated. You must monitor at the frequencies stated and meet the specified emission limits unless your permit states alternative requirements.

Emission limit – 5mg/m³ (where it is inappropriate to fit a fabric filter due to the potential effects of deflagration on the filter, the limit is 10mg/m³).

In addition, the following monitoring is required from all mechanical treatment of WEEE when the substance concerned is identified as relevant based on your facility’s emissions inventory.

Monitoring standard – EN 1948-1, -2 and -4.

Monitoring standard – EN 1948-1, -2 and -3.

Periodic monitoring results should normally consist of the average value of 3 consecutive measurements of at least 30 minutes each. For some parameters, due to analytical limitations, a longer sampling period may be required.

Monitoring frequencies may be reduced if the emission levels are proven to be sufficiently stable over time.

1. Your facility’s emissions inventory must include information about the relevant characteristics of point source emissions to sewer or water, such as:

2. For relevant emissions to water or sewer identified by the emissions inventory, you must carry out monitoring of key process parameters (for example, waste water flow, pH, temperature, conductivity, or BOD) at key locations. For example, these could either be at the:

3. For the following types of discharges, you must monitor point source emissions to water or sewer for the substances listed using the monitoring standards stated. You must meet the specified emission limits unless your permit states otherwise.

The requirement is to monitor for either total organic carbon or chemical oxygen demand.

Monitoring standard – EN ISO 9377-2.

Monitoring standard – various EN standards available.

Monitoring frequencies may be reduced if the emission levels are proven to be sufficiently stable over time.

Monitoring frequencies for discharges to sewer may be reduced if the downstream waste-water treatment plant abates the pollutants concerned.
