Kettleman Lane <br /> Gasoline Cleanup <br /> We have reviewed your letter of May 7 and after additional research have an <br /> alternative for your consideration. We agree that extending a discharge <br /> pipe 470 feet up Hutchins Street (which has recently been reconstructed) is <br /> unreasonable. We suggest you connect to the industrial waste line located <br /> in Kettleman Lane. <br /> The 30" industrial waste line is located approximately on the north left <br /> turn lane line and is approximately 3 feet deep (to the top of pipe) . The <br /> 42" storm drain in Highway 12 (Kettleman Lane) is south of the centerline, <br /> approximately at the south left turn lane line and is much deeper. <br /> Enclosed are City drawings 71D32 and 78D68 showing these facilities. Also <br /> enclosed is an exhibit from a recent City Council meeting showing the lane <br /> striping dimensions. <br /> There are a number of advantages to connecting to the industrial waste <br /> line. This lines carries water that is primarily cannery waste and is used <br /> for irrigation at the City's treatment plant. Thus, more beneficial use <br /> would be obtained compared to discharge to the sanitary sewer. Also, the <br /> connection and service charges will be lower than those for discharge to <br /> the domestic sewer. <br /> Our construction requirements would include a manhole and a jacked pipe in <br /> Kettleman Lane and a meter at the treatment unit discharge. It appears the <br /> work could be done with closure of the left turn lane and minimal moving of <br /> the westbound lanes. We will need to issue a discharge permit and wish to <br /> review your NPDES permit requirements to avoid duplication of effort. You <br /> will also need to obtain a Caltrans encroachment permit. <br /> We also have a concern about the relatively low flow rate in that the <br /> cleanup operation will take longer. We wish to reactivate Municipal Well <br /> #12 as soon as possible and would appreciate receiving an explanation as to <br /> the choice of flow rate and its effect on the cleanup time. <br /> LBROWN&C.4/TXTW.01L <br />
