i <br /> BMP C153: Material Delivery, Storage and Containment <br /> i Purpose Prevent,reduce,or eliminate the discharge of pollutants to the <br /> i � <br /> stormwater system or watercourses from material delivery and storage. <br /> Minimize the storage of hazardous materials on-site, store materials in a <br /> designated area, and install secondary containment. <br /> z <br /> Conditions of Use These procedures are suitable for use at all construction sites with <br /> delivery and storage of the following materials: <br /> Petroleum products such as fuel,of I and grease <br /> • Soil stabilizers and binders (e.g.Polyacrylamide) <br /> Fertilizers,pesticides and herbicides <br /> • Detergents <br /> • Asphalt and concrete compounds <br /> • Hazardous chemicals such as acids, lime, adhesives, paints,solvents <br /> i and cutting compounds <br /> • Any other material that may be detrimental if released to the <br /> environment <br /> Design and The following steps should be taken to minimize risk: <br /> Installation Temporary storage area should be located away from vehicular traffic, <br /> eSpecifications near the construction entrance(s), and away from waterways or storm <br /> drains. <br /> Material Safety Data Sheets (MSDS) should be supplied for all <br /> materials stored. Chemicals should be kept in their original labeled <br /> E <br /> containers. <br /> Hazardous material storage on-site should be minimized. <br /> I , <br /> • Hazardous materials should be handled as infrequently as possible. <br /> • During the wet weather season(Oct 1 —April 30), consider storing <br /> '= materials in a covered area. <br /> !: Materials should be stored in secondary containments,such as earthen <br /> dike,horse trough, or even a children's wading pool for non-reactive <br /> materials such as detergents, oil,grease, and paints. Small amounts of <br /> material may be secondarily contained in"bus boy" trays or concrete <br /> mixing trays. <br /> • Do not store chemicals, drums,or bagged materials directly on the <br /> ground. Place these items on a pallet and,when possible, and within <br /> r secondary containment. <br /> • If drums must be kept uncovered, store them at a slight angle to reduce <br /> } <br /> ponding of rainwater on the lids to reduce corrosion. Domed plastic <br /> covers are inexpensive and snap to the top of drums, preventing water <br /> i <br /> from collecting. <br /> Vohnne H--Construction Stornnwder Pollution Premnlio►r-August 2012 <br /> 4-45 <br /> .
