September 14, 2006 <br /> FOR: Mr. Mike Huggins, R.E.H.S., R.D.I., Land Use Program Supervisor <br /> Mr. Greg Oliveira, R.E.H.S., Lead Senior <br /> San Joaquin County Environmental Health Department <br /> 304 East Weber Ave. <br /> Stockton, CA 95202 <br /> PROTECT: Carmelo Industrial Park, CPC Navarra-Carmelo Phase 2 <br /> 23833 South Chrisman Road,Tracy <br /> Land Use Application: SA-99-103, SR0047971 <br /> SUBJECT: On-site Wastewater Management System Study Addendum <br /> Reference is made to the Studies completed for the Carmelo Industrial Park project at the location listed <br /> above. The Report encompassing these Studies was found to be acceptable with the conditions referenced <br /> in the EHD Response Document, dated September 5, 2006 (See Attached). <br /> Item 5 states that the Department is requiring an addition to the primary filter bed to accommodate the <br /> additional effluent flow of 462 gpd anticipated from Phase 2. This brings the required primary filter bed <br /> area to 1,900+462=2,362 s.f. The 100%replacement area must be this area, or greater. As noted in the <br /> Report, the existing primary filter bed consists of a 300 s.f.bed, a 1,000 s.f.bed and a 600 s.f. bed, for a <br /> total of 1,900 s.f. The 100%replacement area currently consists of a 780 s.f. bed, another 780 s.f.bed, a <br /> 246 s.f. bed and a 136 s.f. bed, for a total of 1,942 s.f of replacement/reserve area. <br /> Item 6 asks to provide a revised site plan to EHD showing the area where the additional primary filter bed <br /> capacity will be located, along with the 100%replacement area. The attached revised site plan shows the <br /> additional primary filter bed area of 460 s.f. has been added to the furthest west(adjacent to the <br /> EnviroServer) filter bed(originally 300 s.£). Additional 300 s.f of replacement area has been added <br /> directly west of this westernmost filter bed, and 653 s.f. of replacement area has been added to an area <br /> directly north of the existing building and west of the entrance driveway. These changes have been <br /> "clouded"on the attached site plan for clarification. Mr. Bernie Dietz of Dietz Irrigation, who installed the <br /> original EnviroServer and filter bed, will be securing a permit to install this additional filter bed area as <br /> soon as possible. Remaining Items 1-4 of the EHD Document will be addressed in a future Addendum. <br /> The total primary filter bed area will now be: 300 s.f +460 s.f. + 1,000 s.f. + 600 s.f. =2,360 s.f. <br /> The total replacement area will now be: 653 s.f + 300 s.f. + 320 s.f. + 780 s.f. +246 s.f. + 136 s.f. =2,435 s.f. <br /> Respectfully submitted �v rRc,vf, h- <br /> ��� <br /> CHESNEY CONSULTING <br /> ND. 04675 <br /> � m <br /> on Chesney,R.E.A.
