Source: Califomia Air Resources Board (2122/2007) <br />The prevailing Congestion Management Plan in the project area is the Southern <br />Califomia Association of Governments' (SCAG) 2004 Regional Transportation <br />Plan (RTP}, which set forth a series of policies for managing the flow of traffic <br />throughout the SCAG region. Long-term operation of the sewer pump facility and <br />appurtenances would not generate substantial traffic volumes which could <br />interfere with the goals or policies of the RTP. Implementation of the proposed <br />project also would not interfere with any public transportation facilities or policies. <br />Page 34 of 64 <br />75E-38 <br />
