BACKGROUND
This service provides bins for the collection of grit and screenings materials, the subsequent removal of the full bins, related services such as moving bins on Sundays, and taking drying bed material and disposing the materials at the Orange County Waste and Recycling's (OCWR's) Frank Bowerman Landfill in Irvine. Grit and screenings materials are continually collected as part of the preliminary treatment process at both Orange County Sanitation District (Sanitation District) Plant Nos. 1 & 2. Drying bed material is similar to materials removed from sewer lines and plant processes, mixed with sawdust. The Sanitation District pays OCWR separately for the disposal fees.
Effective July 2019, Sanitation District Compliance staff are now administering this contract because of new CalRecycle online reporting requirements and necessary internal documentation required as a result. However, the budget line item is still maintained by Operations & Maintenance (O&M), similar to the biosolids budget line item in which Compliance does contract management for O&M's budget.
RELEVANT STANDARDS
* 24/7/365 treatment plant reliability
* Comply with environmental permit requirements
* Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting
PROBLEM
The current contract for grit and screenings removal expires on June 30, 2020.
