Our story
Who HCI Environmental is
HCI Environmental & Engineering Service is a full-service environmental management company founded in 2000. From headquarters at 1680 Commerce Street in Corona, HCI transports and disposes of hazardous and non-hazardous waste, responds to chemical spills around the clock, and performs environmental construction, decontamination, soil excavation and demolition for businesses, municipalities and government agencies across Southern California.
One licensed team covers the whole job. HCI holds a California contractor license with Class A General Engineering, C-21 Demolition and HAZ certifications, an EPA identification number, USDOT registration and a California hazardous materials transportation license. HAZWOPER-trained crews and drivers package, label, manifest and transport your waste to permitted disposal facilities, and the signed manifest copies and certificates come back to you.
Public agencies have put that model under contract. HCI holds citywide on-call and master agreements with cities across the Inland Empire, Orange County and Los Angeles County, works as a qualified contractor for several County of Riverside departments, and maintains firing range, emergency response and hazardous waste contracts with counties, water districts and state departments. Private customers range from small shops on a drum route to plants scheduling bulk tanker loads.

Why HCI
What makes HCI different
HCI has run hazardous waste, spill response and remediation jobs for industry and government since 2000, with its own crews, trucks and licenses.
One licensed team, start to finish
Transport, disposal coordination, emergency response, remediation, construction and demolition under one set of licenses. One crew, one point of contact and one set of paperwork from your dock to the permitted facility.
A live operator, 24 hours a day
During business hours, 8:00 am to 5:00 pm Pacific, a customer service representative answers directly with your waste streams, profile sheets and manifests in front of them. After hours, a live operator takes the call and starts the response procedure.
Fast quotes and scheduling
Most routine quotes come back in writing within 24 hours. Once the quote is approved and the signed documents are in, pickups are typically scheduled within two to three business days. Most projects can be performed on a 24/7 basis.
Help staying compliant
HCI shares regulatory fact sheets, helps find answers from the right agency, provides shipped waste quantities for your reporting period on request, and offers current customers one complimentary site visit each year to review how waste is being handled.
