Project Name: Chemical Facility Decommissioning

Location: La Mirada, CA

Job Type: Decontamination and Demolition


Ensuring the safe decontamination and demolition and subsequent closure of a chemical manufacturing facility. For 20 years, this site was home to a cleaning product manufacturer who used the facility to mix and store various dry and wet chemicals – an industrial activity that results in a high-risk of chemical reactions due to incompatible chemicals mixing and further site contamination during the decommissioning process. E&E was tasked with shutting down and restoring the property to a clean shell with all of the infrastructure removed, so the client could fulfill the requirements of their lease termination agreement.



Client Accessibility – In addition to the standard challenges related to handling hazardous chemicals, this project faced unique challenges related to client safety and accessibility. During much of the project, several of the company’s employees still occupied the office space – tasked with shipping remaining products and selling salvageable equipment. E&E’s team maintained a close working relationship with the company and its employees to ensure a safe working space, remain on schedule, and deliver on time.

COC Containment – Due to the plethora of in-ground, mid-height, and roof level process lines throughout the facility, many of which still contained residual manufacturing chemicals, E&E needed to develop effective controls to facilitate their safe decommissioning and eventual removal. The chemical plant had its own wastewater treatment facility situated to the far corner of the premises to which the site-wide wastewater conveyance lines terminated. E&E re-developed its demolition plan in stages to carefully migrate from the furthest point away from, and subsequently toward, the treatment plant, utilizing the pre-existing wastewater conveyance infrastructure to direct all rinsate/decon water to the treatment facility where it was subsequently treated accordingly. On completion of the chemical facility decommissioning, E&E obtained permits for the sewer abandonment and subsequent capping and closing of the sewer connection along with the final demolition of the treatment plant.
