a a <br /> V <br /> • All vehicles, equipment, and petroleum product storage/dispensing areas will be <br /> inspected regularly to detect any leaks or spills, and to identify maintenance needs to <br /> prevent leaks or spills. <br /> • Spill prevention measures, such as drip pans,will be used when conducting maintenance <br /> and repair of vehicles or equipment. <br /> • Contaminated surfaces shall be cleaned immediately following any discharge or spill <br /> incident. <br /> Concrete and grout: Process water and slurry resulting from concrete work will be prevented <br /> from entering the waters of the State by implementing Concrete Handling measures(BMP <br /> C151). <br /> In order to prevent,reduce, or eliminate the discharge of pollutants from material delivery and <br /> storage to the stormwater system,Material Delivery and Storage Contamination(BMP C153) <br /> shall be implemented. <br /> Sanitary wastewater: Portable sanitation facilities will be firmly secured,regularly maintained, <br /> and emptied when necessary. <br /> Solid Waste: Solid waste will be stored in secure, clearly marked containers. <br /> Element#10—Control Dewatering <br /> Dewatering is not anticipated,but if dewatering of trenches and/or excavations is needed it will <br /> be completed under the direct supervision of the project CESCL. All stormwater that leaves the <br /> project site will comply with permit discharge requirements. <br /> Element#11—Maintain BMPs <br /> All temporary and permanent erosion and sediment control BMPs shall be maintained and <br /> repaired as needed to assure continued performance of their intended function. Maintenance and <br /> repair shall be conducted in accordance with each particular BMP's specifications. Visual <br /> monitoring of the BMPs will be conducted at least once every calendar week and within 24 hours <br /> of any rainfall event that causes a discharge from the site. If the site becomes inactive, and is <br /> temporarily stabilized, the inspection frequency will be reduced to once every month. <br /> All temporary erosion and sediment control BMPs shall be removed within 30 days after the <br /> final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped <br /> sediment shall be removed or stabilized on site. Disturbed soil resulting from removal of BMPs <br /> or vegetation shall be permanently stabilized. <br /> DAVID EVANS AND ASSOCIATES,INC. <br /> GRANDVIEW APARTMENTS CLUBHOUSE MARCH,2017 <br /> STORMWATER SITE PLAN PAGE 14 <br />
