The fueling or maintenance site shall be protected from storm water, <br /> shall be on level ground, and shall be located at least 15 m from drainage inlets or watercourses. The WPCM shall inspect <br /> the fueling or maintenance site regularly. Mobile fueling or maintenance shall be kept to a minimum. <br /> The Contractor shall use containment berms or dikes around the fueling and maintenance area. Adequate amounts of <br /> absorbent spill cleanup material and spill kits shall be kept in the fueling and maintenance area and on fueling trucks. Spill <br /> cleanup material and kits shall be disposed of immediately after use. Drip pans or absorbent pads shall be used during <br /> fueling or maintenance unless performed over an impermeable surface. <br /> Fueling or maintenance operations shall not be left unattended. Fueling nozzles shall be equipped with an automatic <br /> shutoff control. Vapor recovery fueling nozzles shall be used where required by the Air Quality Management District. <br /> Nozzles shall be secured upright when not in use. Fuel tanks shall not be topped-off. <br /> The Contractor shall recycle or properly dispose of used batteries and tires. <br /> Paving,Sealing,Sawcutting,and Grinding Operations <br /> The Contractor shall prevent the following material from entering storm drain systems or water courses: <br /> A. Cementitious material, <br /> B. Asphaltic material, <br /> C. Aggregate or screenings, <br /> D. Grinding or sawcutting residue, <br /> E. Pavement chunks,or <br /> F. Shoulder backing. <br /> The Contractor shall cover drainage inlets and use linear sediment barriers to protect downhill watercourses until paving, <br /> sealing, sawcutting, or grinding operations are completed and excess material has been removed. Drainage inlets and <br /> manholes shall be covered during the application of seal coat,tack coat,slurry seal,or fog seal. <br /> During the rainy season or when precipitation is predicted, paving, sawcutting, and grinding operations shall be limited <br /> to places where runoff can be captured. Seal coat,tack coat,slurry seal,or fog seal operations shall not begin if precipitation <br /> is predicted for the application or the curing period. The Contractor shall not excavate material from existing roadways <br /> during precipitation. <br /> The Contractor shall vacuum up slurry from sawcutting operations immediately after the slurry is produced. Slurry shall <br /> not be allowed to run onto lanes open to public traffic or off the pavement. <br /> The Contractor shall collect residue from portland cement concrete grinding operations with a vacuum attachment on the <br /> grinding machine. The residue shall not be left on the pavement or allowed to flow across the pavement. <br /> Material excavated from existing roadways may be stockpiled as provided in "Stockpile Management" of these special <br /> provisions if approved by the Engineer. Asphalt concrete chunks used in embankment shall be placed above the water table <br /> and covered by at least 0.3-m of material. <br /> Substances used to coat asphalt trucks and equipment shall not contain soap,foaming agents,or toxic chemicals. <br /> Thermoplastic Striping and Pavement Markers <br /> Thermoplastic striping and preheating equipment shutoff valves shall work properly at all times when on the <br /> construction site. The Contractor shall not preheat, transfer, or load thermoplastic within 15 m of drainage inlets or <br /> watercourses. The Contractor shall not fill the preheating container to more than 150 mm from the top. Truck beds shall be <br /> cleaned daily of scraps or melted thermoplastic. <br /> The Contractor shall not unload, transfer, or load bituminous material for pavement markers within 15 m of drainage <br /> inlets or watercourses. All pressure shall be released from melting tanks before removing the lid to fill or service. Melting <br /> tanks shall not be filled to more than 150 mm from the top. <br /> The Contractor shall collect bituminous material from the roadway after marker removal. <br /> Pile Driving <br /> The Contractor shall keep spill kits and cleanup material at pile driving locations. Pile driving equipment shall be parked <br /> over drip pans,absorbent pads,or plastic sheeting where possible. When not in use,pile driving equipment shall be stored at <br /> least 15 m from concentrated flows of storm water, drainage courses, or inlets. The Contractor shall protect pile driving <br /> equipment by parking it on plywood and covering it with plastic when precipitation is predicted. The WPCM shall inspect <br /> the pile driving area every day for leaks and spills. <br /> The Contractor shall use vegetable oil instead of hydraulic fluid when practical. <br /> Contract No. 10-OM7104 <br /> 143 <br />
