44� *.4w/ 2) The ponds demonstrated minimal weeds at banks of all locations and minimal erosion was noted. The Maintenance Facility Manager, Steven Schnaber stated that he had just applied round-up the day before. Round-up is sprayed to control weeds at all perimeter locations of the ponds and the fenced sewage treatment plant. A perimeter fence surrounds all the ponds and is not easily accessed. Pond #2 and Pond #3 were seasonally full due to the rains over the last several months and it was observed upon inspection that a significant amount of water was present in both ponds. Once the float is alarmed in pond #1, wastewater is directed into pond #4 for overflow. There are no aerators in Pond #2, or Pond #3. A minimal amount of duckweed was observed at Pone #4. The only method by which duckweed can be removed is by mechanical means such as a raking and or a skimming technique. Continue to maintain duckweed and control by mechanical removal methods. 3) The wastewater plant appears to be operating and functioning within San Joaquin County Sewage Standards. All areas are well maintained and the staff monitors the plant on a daily basis. The findings of the inspection were discussed with Steve Schnaber, Maintenance Facility Manager. Continue to maintain and operate sewage package treatment plant accordingly. Excellent maintenance and continued surveillance of the water monitoring is having a positive impact on the operation and management of the wastewater treatment plant. Erosion control measures have been implemented in Pond #1. Rip-rap has been placed on the south-facing bank to prevent potential erosion. No erosion is taking place at this time. Pictures have been taken for the file and a copy of all pictures will be sent to responsible parties. 4) For the permitting year of 2011, analytical testing and reporting to the Environmental Health Department (EHD) may be required as part of a condition of the permit. The monitoring frequency is to be determined at a later date by the EHD.
