Details

This regulatory position statement (RPS) does not change your legal requirement to have an environmental permit for a waste operation when you treat diluted non-hazardous pesticide washings using lined biobeds or above ground biofilters if the treatment site is within either:

• a groundwater source protection zone 1 (SPZ1)

• 250 metres of a borehole used to supply water for domestic or food production purposes

However, the Environment Agency will not normally take enforcement action if you do not comply with this legal requirement if you meet the requirements in the RPS.

The regulatory position does not apply to any other legal requirements.
