Economic

Amprius will create a framework to provide quality jobs to the Brighton, CO and the Northern Denver community. Our plan is to provide high wages that will benefit the community in the Northern Denver Metro Area and disadvantaged communities in the area. We will be adding more than 300 high paying jobs (104% the average job wage in Adams County), and plan to hire local contractors and procure local goods and services to upgrade the plant.

FAQ:

Health & Safety

At Amprius we will be using a variety of emission control devices to make sure we do not exceed the required limits on emissions. This includes, but is not limited to, state-of-the-art dust collection and vacuum systems, recovery systems and other abatement systems that prevent dust and other emissions from escaping into the atmosphere. The plant will operate in compliance with EPA, Colorado Department of Public Health and Environment, and other environmental permits.

We don’t anticipate incidents that would affect the neighborhood. We are working closely with the city of Brighton, Adams County and the Fire Marshal to ensure we meet all regulations. If an incident occurred that requires public notification, the City’s Incident Command system would be initiated, and they would implement their Emergency Action Plans including communication with the community.

At the highest level, the International Building Code (IBC) and National Fire Protection Association (NFPA) codes govern all new construction and are supplemented with local codes and regulations. Specific codes that will oversee the Brighton facility include (but aren’t limited to):
   • 2021 International Residential Codes
   • 2021 International Plumbing Codes
   • 2021 International Mechanical Codes
   • 2021 International Fuel Gas Codes
   • 2021 International Energy Conservation Codes
   • 2021 Property Maintenance Codes
   • 2021 Existing Building Codes
   • 2021 Swimming Pool & Spa Codes
   • 2021 Fire Codes

FAQ:

Manufacturing

Our key battery components and batteries will be made in the U.S.A. Manufacturing materials come from a variety of sources based both in the US and overseas, just like your iPhone. But unlike your iPhone and most electronics in our homes, manufacturing will be based in Brighton, Colorado, U.S.A. Our lithium-ion batteries are used by the U.S. Army to protect our national security and other companies to improve our communications.

We will outfit the facility with manufacturing equipment required to manufacture the battery components, including electrode manufacturing and cell assembly. This includes tools to support mixing, coating, calendaring, slitting and stacking. In addition, the company plans to install Centrotherm deposition machines, currently used in volume production of semiconductor chips and solar panels, to manufacture its silicon anode.

These will continue to develop as the designs for the facility are produced. They include things such as: spill / leak detection, remote emergency shut offs, firewalls, code-compliant hazardous occupancy areas, code-compliant egress (emergency exit) paths for employees, etc. During construction, all contractors and vendors will have safety action plans on file and conduct daily safety assessments before starting work for the day.
