CITY OF EVERETT STORMWATER MANAGEMENT MANUAL 3.2.20 BMP C153: Material Delivery, Storage and Containment Purpose Prevent,reduce,or eliminate the discharge of pollutants from material delivery and storage to the sormwater system or watercourses by minimizing the storage of hazardous materials onsite, storing materials in a designated area, and installing secondary containment. Conditions of Use These procedures are suitable for use at all construction sites with delivery and storage of the following materials: • Petroleum products such as fuel, oil and grease • Soil stabilizers and binders(e.g., Polyacrylamide) • Fertilizers,pesticides and herbicides • Detergents • Asphalt and concrete compounds • Hazardous chemicals such as acids, lime, adhesives,paints, solvents and curing compounds • Any other material that may be detrimental if released to the environment. Design and Installation Specifications The following steps shall be taken to minimize risk: 1. Temporary storage area shall be located away from vehicular traffic, near the construction entrance(s), and away from waterways or storm drains. 2. Material safety data sheets shall be supplied for all materials stored. Chemicals shall be kept in their original labeled containers. 3. Hazardous material storage on site shall be minimized. 4. Hazardous materials should be handled as infrequently as possible. 5. During the wet weather season (October 1 to April 30), storage of materials in a covered area shall be considered. 6. Materials should be stored in secondary containments, such as earthen dike, horse trough, or even a children's wading pool for non-reactive materials such as detergents, oil,grease,and paints. Small amounts of material may be secondarily contained in"bus boy"trays or concrete mixing trays. 7. Chemicals, drums, or bagged materials shall not be stored directly on the ground. Place these items on a pallet and,when possible, in secondary containment. 8. If drums must be kept uncovered, store them at a slight angle to reduce ponding of rainwater on the lids to reduce corrosion. Domed plastic covers are inexpensive and snap to the top of drums, preventing water from collecting. Material Storage Areas and Secondary Containment Practices: i. Liquids,petroleum products, and substances listed in 40 CFR Parts 110, 117, or 302 shall be stored in approved containers and drums and shall not be overfilled. Containers and drums shall be stored in temporary secondary containment facilities.
