The City of Los Angeles is continuously investigating, developing, and implementing changes to our biosolids management program.

• 2011 Interim Audit – The Bureau of Sanitation’s communication process for alerting and informing the public about changes and updates to the program are effective, as well are communications between contractor, farmer, and City staff at Green Acres farm. The Bureau’s public outreach and communications program is effective and has resulted in positive feedback and recognition from several sources, including other City Departments and outside governmental agencies and organizations. The Bureau of Sanitation’s process for maintaining contractor control has resulted in improved operations, continued regulatory compliance, and allowed continued use of biosolids at Green Acres Farm. The City had one minor noncompliance regarding an inaccurate site photo at the Griffith Park Composting Facility. To view result click here.
