" Agenda Date'NOVetnhef 1,2005 Agetida Item:No. 55 ACKGROUND In 2003,the Board directed the Department to provide periodic reports of the Olivera Egg Ranch located at 4140 Canada Road,Gilroy,California,and to work with the property owner and facility operator to ensure that the ranch would operate consistently with accepted standards and practices for a commercial poultry operation. In order to track improvement,the Department set up a quality performance measure for Olivera Egg Ranch.The measure monitors adult fly control,as determined by weekly adult fly spot card counts. Adult fly spot cards are a scientifically accepted assessment tool to determine fly abundance by correlating manure management and adult domestic fly control at the facility.Fly spots are measured on a weekly basis using 16 established spot card locations throughout the poultry houses.The weekly average of these spot cards helps the operator manage and,consequently, modify its fly abatement program.Fly spots left on the cards by adult flies are counted and an average per card per week is developed and recorded An average of 75 or greater"triggers"a preliminary finding of a public nuisance,50 or greater prompts the facility to increase its abatement activities,while less than 50 becomes a statistical entry in the database. The Department has continued to monitor the poultry facility on the same weekly schedule;however,report backs to the Board are made to coincide with the historical months of increased adult fly activity.Reports to the Board are as follows. first reporting period is May,June,and July with a report to the Board at the first meeting in August;second reporting period is August,September,and October with a report to the Boards first meeting in November.A report will automatically be transmitted to the Board,as outlined in the Compliance Agreement,in the event that the weekly inspection discloses excess adult fly spot. STEPS EULLOW N APPROVAL No action is being requested of the Clerk of the Board Transmittal is informational only.
