Create a contained and covered area on the site for the storage of bags, cement, paints, flammable, oils, fertilizers, pesticides, or any other materials used on the project site that have the potential for being discharged to the storm drain system through being windblown or in the event of a material spill. f.) Never clean machinery, tools, brushes, etc., or rinse containers into a street, gutter, or storm drain. g.)
