The Control of Pollution Act (CoPA) 1974 is an act of legislation giving Local Authorities (LAs) powers for controlling noise and vibration from construction sites and other similar works. The Act enables a Local Authority (LA), in whose area work is going to be carried out, or is being carried out, to serve a notice of its requirements for the control of site noise on the person who appears to the LA to be carrying out the works and on such other persons appearing to the local authority to be responsible for, or to have control over, the carrying out of the works.
