The Environment Agency requires all excavated waste to be classified before disposal / treatment. Utilities have been able to do this in two ways previously: unplanned works followed RPS 211 and Planned works followed WM3.
A solution was required to better deal with waste generated from unplanned works and the Environment Agency was open to Street Works UK proposing a solution that would work for its members.
A risk assessment based approach was trialled by Street Works UK members and approved by the Environment Agency for use to classify excavated waste for qualifying work.
