Hazardous Materials

In Monterey Park, commercial and industrial businesses that use hazardous materials [3] include dry cleaners, film processors, auto service providers, landscape contractors, and computer component manufacturers, among others. Residences also generate household hazardous wastes in the form of paints, thinners, pesticides, fertilizers, etc.

Hazardous Waste Regulations

Hazardous waste generators and users in the city are required to comply with regulations enforced by several federal, state, and county agencies. The regulations aim toward reducing risk associated with human exposure to hazardous materials and minimizing adverse environmental effects. The city's Fire Department coordinates with the Health Hazardous Materials Division of the Los Angeles County Fire Department to ensure appropriate reporting and compliance.

Emergency Management System Preparation

Despite all efforts to guard against health risks associated with hazardous materials, such materials can be released accidentally into the environment as a result of a natural disaster or improper storage and handling. The city's Standardized Emergency Management System, or SEMS, prepares city staff to react quickly and specifically to any hazardous materials accident, with the Fire Department leading the response team. The SEMS includes provisions for the Fire Department to maintain records of all hazardous materials stored and used at businesses in the community, thus ensuring appropriate response to any individual incident.

To address household hazardous wastes, the city cooperates with Los Angeles county to sponsor programs that heighten community awareness of household hazardous wastes and the importance of proper storage and disposal.
