The residues that stop a cleaning scope
Antifoul paint residue, hull scrapings and the dust from sanding a coated hull are not general waste. They contain compounds that are regulated precisely because they are designed to be biologically active in water, and washing them into a drain near a waterway is a serious matter for the operator. A cleaning contractor should not be collecting, moving or disposing of that material.
What is in scope is everything else: fibreglass dust in workshop areas, general debris, amenities, offices, floors away from the treatment zone and the surrounds of the containment area. Drawing that line clearly at the quoting stage protects the operator, who carries the environmental obligation, and prevents an assumption that a cleaning visit covers a compliance task. Recording that the boundary exists, and where it sits physically, is what makes the exclusion workable rather than a clause nobody can apply on site.
