I <br /> All of APG's centrifuges are controlled with an industry leading, in-house <br /> developed control system. This system incorporates all functions of the centrifuge <br /> and intelligently controls pumping rates of slurry and polymer, back drive motor <br /> speed and other process elements based on operator input. With this system, <br /> APG can maximize centrifuge throughput, cake dryness, and capture while <br /> minimizing polymer dosage. <br /> The cake or solids portion will drop onto a horizontal belt conveyor and then a <br /> stacking conveyor and temporarily staged on the asphalt pad area. The solid will <br /> ' then be loaded into a dump truck, be weighed on the scale and then stockpiled in <br /> the designated bunkers for this project. The centrate or liquid portion will exit out <br /> ' the opposite end of the centrifuge and will drain by gravity into a tank. The <br /> centrate then will be pumped back through the piping to AC1. <br /> Safety & Environmental <br /> Safety influences our actions, guides our decisions and shapes our culture. We <br /> believe our employees are entitled to productive, healthy careers in an incident- <br /> free workplace. We extend this philosophy further - to include our employees' <br /> family members, our contractors, all other APG stakeholders and every <br /> community in which we perform our work. All personnel are trained in First Aid, <br /> H2S Alive, WHMIS and most are trained in Confined Space Entry & Rescue. We <br /> comply with the latest OSHA and OH&S safety standards as well as the workers <br /> compensation board and any other local jurisdictions in place where the work will <br /> be performed. <br /> The Electrical buildings will contain fire extinguishers and a first aid kit will be kept <br /> in the onsite office. While on site, all personnel will wear proper Personal <br /> Protective Equipment including steel toe boots, hardhat, and safety glasses with <br /> side shields. The dredger will wear a life jacket at all times while on, or traveling <br /> to or from the dredge. He will also be in constant, two-way radio contact with the <br /> dewatering site crew. <br /> All precautions will be taken to avoid spills during the work plan. These <br /> precautions will include Standard Operating Procedures (SOP) being in place, <br /> containment, tarping, berming, and proper procedures. Any and all spills will be <br /> mitigated by having SOP's in place, using truck mounted spill kits, vacuum trucks, <br /> tabsorbents, and proper procedures. <br /> E <br /> I <br /> City of Everett 2020 t3iosotida Removal Project—Work Order#llT 3705-11 March 6,2020 - Page 3 <br />
