OSIon;naaquain Regional7rainsit District <br /> In addition to the above, the importance of reducing the amount of <br /> free oil by removing any free oil from the system shall be stressed <br /> during the said educational forums. <br /> Process optimization, production process changes: The <br /> SJRTD's WM team shall also continue to evaluate the economic <br /> feasibility of conducting the following process changes: <br /> ❖ Cost benefit analysis to retrofit the existing oil/water <br /> separator with an oil coalescing mechanism or equivalent <br /> technology that shall further enhance the oil/sludge removal <br /> and segregation capability of the system from the clarified <br /> water in the system. <br /> * Cost benefit analysis to change out the system and replace <br /> the existing oil/water separator with a state of the art <br /> oil/water separator, which is equipped with an integrated <br /> coalescing plate or other equivalent and more superior <br /> technology, which will further enhance the oil/sludge removal <br /> efficiency of the system, while minimizing the amount of any <br /> trapped water. Both of the above source reduction <br /> strategies shall further eliminate or reduce the quantity of <br /> water that is pumped from the oil/water separator, hence, <br /> reducing the amount of hazardous waste pumped by the <br /> contractor. <br /> • Multi-media environmental Compliance analysis: The SJRTD's WM <br /> team will take into account the impact of the above measures and the <br /> use of any new oil/water separator and its water quality improvement <br /> function as well as any consequential impacts to the SJRTD's current <br /> wastewater pre-treatment permit issued by the City of Stockton; in <br /> 32 <br />
