Chula Vista Environmental Services is a City of Chula Vista department operating the South Bay Household Hazardous Waste Collection Facility at 1800 Maxwell Road, inside the Public Works Operations Center. The facility accepts paint, automotive fluids, pesticides, motor oil, e-waste, and other household toxics at no charge from residents of Chula Vista, Imperial Beach, National City, and unincorporated San Diego County — waste streams that ultimately route through the Republic Services Otay Landfill and Compost Facility for final processing. No appointment is required, and proof of residency via California ID or a recent utility bill is the only prerequisite for drop-off. The on-site Reuse Center redistributes paint, automotive products, and household chemicals that arrive in usable condition, allowing residents to claim up to fifteen gallons of paint and five household chemical items per calendar month — a diversion model that complements the panel-recycling and e-waste recovery work at Saturn Solar Cleaning. The facility processes Category 1 through Category 9 DOT-classified materials including flammable liquids, corrosives, oxidizers, and poison-class pesticides under California Department of Toxic Substances Control permit requirements.
