New EA approach to hazardous pollutants discharges by Nick Boley

The Environment Agency will be introducing more stringent rules covering discharges of hazardous chemicals in surface waters. following a partial response to a consultation on this subject which closed in December 2013 to amend the Environmental Permitting Regulations 2010.

The procedure for screening hazardous pollutants in water discharges will be tightened, with the emphasis on the more toxic pollutants and is aimed to deliver compliance with the agency’s “no deterioration” policy which requires “control of discharges which cause more than 10% deterioration against the EU Environmental Quality Standard (EQS)”.

One of the main concerns about this change of direction is from those responsible for measuring pollutants in laboratories – including water companies. The methods of analysis available for many of the most highly toxic pollutants which would be caught by this change struggle to cope with the current levels as specified in the EQS and so there is a potential large cost to laboratories to gear up their procedures to cope. The ability of measurement methods to enforce and monitor pollution under any regulatory regime is an important aspect and should not be ignored.
