Summary
CAR contains General Binding Rules (GBR) for certain low risk activities. Compliance with the GBR is mandatory for the management of surface water run-off, as described below:
GBR10b: Discharge of water run-off from a construction site to the water environment where the site, including any constructed access tracks does not:
i. exceed 4 hectares;
ii. contain a road or track length in excess of 5km; or
iii. include any area of more than 1 hectare or any length of more than 500m on ground with a slope in excess of 25°.
Note that where activities fall below or within the GBR10b threshold requirements for surface water discharges but still cause pollution incidents, SEPA may as part of the enforcement process and where appropriate, escalate the level of authorisation and impose a licence.
