These PCD may be inspected and cleaned by the Contractor, including transport and disposal of all pollutants to an authorised tip site by the contractor at times as directed by the Superintendent. Provisional sums are therefore required.

Reports, including digital photographs are to be submitted after each inspection and after each cleaning of the PCD.

All pollutants and other rubbish must be disposed of at EPA approved Waste management Facilities.

Inspection of PCD may be staggered so that a proportion of those PCD are inspected each month in the quarter. i.e. 1/3 inspected month 1, 1/3 inspected month 2, and 1/3 inspected month 3, where no major rainfall event has occurred. Where a rainfall event occurs then after contacting the Superintendent’s Representative for instructions, the contractor will have 2 weeks to inspect all required PCD.
