ENVIRONMENT REPORT 2015

Composition of Chemicals Discharged In 2014, more than 74 per cent (approximately 78,400 tonnes) of the total chemical discharges on the UKCS were PLONOR and five per cent (just over 5,300 tonnes) were classified as SUB. The remaining chemicals fall into other hazard categories and all were discharged under permit.
