HARMFUL SUBSTANCE AND HAZARDOUS SUBSTANCE shall mean any substance which, if introduced into the sea, is liable to create hazards to human health, harm living resources and marine life, damage amenities or interfere with other legitimate uses of the sea. Hazardous substances shall include fuel, oil, paints, varnishes, solvents, pesticides, insecticides, fungicides, algicides, other hazardous liquids.
