1✓ � <br /> The last complete servicing of the plant was conducted on May 30, 2010. All three <br /> systems were activated, checked for function, and found to be working properly. Pumps, <br /> floats, and wiring were inspected to verify proper operation. An air compressor was <br /> replaced. The system is serviced approximately every three months, which includes <br /> pumping of the lift station and the first chamber of each of the three MicroSepTec systems <br /> to remove sludge. The routine service involves inspection of each of the chambers to verify <br /> aeration and testing of the floats and pumps to verify all functions are operating properly. <br /> System number three has been shut down due to the failure of Filter Bed #3. Filter Bed #1 <br /> and Filter Bed #2 are currently operational. <br /> 2. A cement wall with an addition of a three foot fence with privacy slats has been installed <br /> at the east and southeast sides of the plant to enclose the system and to protect the sewage <br /> disposal area from unauthorized persons gaining entry. Pictures were taken on December <br /> 4, 2008 of the original installation and are on record with the permanent file. <br /> 3. Weeds have been removed and other locations within the filter bed areas appear to be <br /> maintained. There is minimal weed growth occurring throughout the filter bed areas. This <br /> facility shall continue to maintain weed control and implement a weed control program <br /> through a consistent spraying of an herbicide approved by the State of California for <br /> application without detrimental effects to the operation and maintenance of the sewage <br /> package treatment plant. The Environmental Health Department {EHD} recommends <br /> landscaping with shallow rooted grasses to aid in the uptake of effluent from the filter beds. <br /> 4. Currently, the tanks are pumped of solids on a routine basis every three months as needed. <br /> Continue to maintain this routine and operation. Filter Bed #1 and Filter Bed #2 are <br /> currently being utilized and shall continue to be the primary filter bed systems from this date <br /> forward. The following was observed at the monitoring ports for Filter Bed #1, Filter Bed #2, <br /> and Filter Bed #3: <br /> Filter Bed#1 - Monitoring observation port not accessible. <br /> Filter Bed#2 -Monitoring observation port not accessible. <br /> Filter Bed#3 - Monitoring observation port not accessible. <br /> 5. For the permitting year of 2010, analytical testing and reporting to the EHD may be required <br /> as part of a condition of the permit. The monitoring frequency is to be determined by the <br /> EHD. The waste water may be required to be sampled for the following constituents by an <br /> employee of a state certified analytical laboratory and results submitted to the EHD: <br /> TKN - Includes Nitrate and Ammonia <br /> BOD - Biological Oxygen Demand <br /> TSS - Total Suspended Solids <br /> pH <br /> CBOD— Carbonaceous Biological Oxygen Demand <br /> 6. The sewage package treatment plant appears to be operating efficiently at Filter Bed #1 and <br /> Filter Bed #2 at the time of inspection. Filter Bed #3 is in failure and will no longer be utilized <br /> as part of the sewage disposal system. Continue to maintain and operate the plant <br /> according to San Joaquin County On - Site Waste Water Disposal Standards. A copy of this <br /> report will be forwarded to Bernie Dietz, Certified Waste Water Treatment Plant Operator. <br /> 2 <br />
