These are the emissions limits and appropriate measures for monitoring emissions to air and water at regulated facilities with an environmental permit to mechanically treat metal waste in shredders.

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

1. Where you are required to monitor emissions to comply with the requirements of your environmental permit you must follow our monitoring your emissions guidance.

2. 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 use MCERTS qualified accredited methods and be done by MCERTs certified staff. You can find further guidance in the Environment Agency’s M1 – Guidance on sampling requirements for monitoring stack emissions.

1. You must apply the following emission limits and monitoring requirements for point source emissions to air.

2. You must comply with any other emission limits or monitoring requirements set in your environmental permit. There may be situations where we set lower emission limits for the following substances listed.

3. You must make sure dust monitoring is done every 6 months using method BS EN 13284-1.

The emission limits are as follows. When using:

4. You must report results as the average value of 3 consecutive measurements of at least 30 minutes each. The 3 consecutive measurements must be representative of the dust and particulate emissions from the operations at the site.

5. You must apply the following emission limits and monitoring requirements for point source emissions to air where they are relevant, based on your facility’s emissions inventory and environmental risk assessment.

6. You must also comply with any other emission limits or monitoring requirements set in your environmental permit.

Where these are identified in your inventory of point source emissions to air you should:

Where these are identified in your inventory of point source emissions to air you should:

Where these are identified in your inventory of point source emissions to air you should:

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

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

3. You must comply with any other emission limits or monitoring requirements set in your environmental permit. We may set lower emission limits for the parameters that follow.

4. In addition to any other parameters specified by your permit, you must monitor the following emissions to water:

You must comply with the following:

You must comply with the following:

You must comply with the following;

If you discharge directly to a water body:

5. If your waste water emissions inventory identified the following parameters are relevant, then you must monitor for them. You should monitor them monthly. There are various standards available for these parameters (for example, EN ISO 11885, EN ISO 17294-2, EN ISO 15586).

These emission limits apply whether the discharge is to a water body or to the sewer:

You should monitor 6-monthly. There is no EN standard available for the monitoring and no emission limit has been set.
