Findings 7 findings

F1 Page 52
High green cart enrollment costs and insufficient bin space are the dominant contributors to low participation rates among multi-family dwellings and businesses. Response: Partially agree – Due to the fact that most of the multi-family dwelling units are older, the lack of space for bins is the biggest problem that we see when trying to have compost bins available for residents. Cost doesn’t seem to be the issue – it's more of a question of where the bins will fit.

Green bin contamination among compliant multi-family dwellings and businesses prevents them from diverting more organic waste. Response: Agree

City, County, and RethinkWaste compliance outreach efforts for multi-family dwellings and businesses could improve because a significant portion of these properties remain non- compliant. Response: Agree

Waste water from the cleaning of trash areas and from rain flow into the storm drain systems. Response: Partially Disagree - The California Water Board’s Municipal Regional Permit 3.0. Provision C.4 lists commercial and industrial outdoor waste storage and disposal areas as reasonably likely to contribute to the pollution of stormwater runoff; as such, these locations are required by the Municipal Regional Permit to implement appropriate best management practices to address pollutant sources. Provision C.4 inspections must include observations for appropriate best management practices to prevent stormwater runoff pollution or unauthorized or illicit discharges from entering the stormwater system. Facilities not in compliance may be required to take corrective action and can face penalties for inadequate best management practices or illicit discharges. Thus, while it is reasonable that wastewater and untreated rainwater from trash areas and cleaning of trash areas may flow into the storm drain it is illegal for facilities to do so, and steps are currently in place to ensure preventative actions are being taken.

An alternate and reliable method to separating waste tons by property type would be analyzing contamination statistics from route audits and waste evaluations. Response: Partially agree - While this would assist with determining waste tons per property type, it would be challenging to track as required under SB 1383 current regulations.
