College Fort Collins, CO. 80524 Ted, Please find below the Hazardous Materials Impact Analysis as required by the PDP process. Hazardous Materials Impact Analysis Part 1 - Provide basic data on the project, site and proposed hazardous materials uses. Project — The project consists of a building footprint of approximately 155,600 sq ft. The Fab is a 4 level building, including the basement, and most of the space is unoccupied equipment space. The Primary occupied space is 40,000 sq ft of integrated circuit fabrication clean room. The other occupied spaces are for break areas, restrooms and locker rooms. The project also has a separate 6,000 sq ft chemical distribution building to the east of the main building and adjacent to the existing chemical buildings on site. Site — The project continues the planned development of the site. The project begins to develop the north west quadrant of the Hewlett Packard property. The project adds 4.3 impervious acres to the existing 55.00 impervious acres already established on the site. The existing perimeter road will be altered to allow for this new building. The existing architectural and landscape themes will be carried forward with this new project. Existing traffic patterns, truck traffic and delivery routes will be used with minor road location modifications in the north west corner. Hazardous materials uses - The integrated circuit fabrication is an additional facility which is very similar to the one currently operating in Building 2, which was originally built in 1977. The facility will use a variety of acids, bases, Shw: c:\data\newfab\,c1ty\HM1A gases and solvents. All these materials are the same ones now in use in Building 2 fab. The new fab is being built to increase capacity of these processes. Chemicals will be stored according to latest codes and will have safety features such as proper separation, leak detection, secondary containment and fire prevention and mitigation methods. Gases will have flow - limiting orifices meeting all current codes to reduce the potential of hazardous release. Process ventilation for acids and bases will be exhausted through water scrubbers, and solvent exhausts will be treated prior to release using a combination of concentration and incineration technologies. Part 2 - Describe likely incident scenarios With the prevention and containment methods to be employed, the most likely possibilities of leak or release incidents are 1) minor leaks relating to transporting the materials and 2) small leaks from containers or process equipment. Leaks discovered on an arriving truck would be stopped and cleaned up before allowing the truck to leave from the site. Leaks of materials in storage might result from leaky or defective containers, or dropped or damaged containers. Leaks relating to process equipment might occur from faulty lines, valves or connections. Part 3 - Describe mitigation actions designed to limit potential for off -site impact to adjacent land uses or environment. - case of leak from loading/unloading operations, a trained hazardous materials team is available on site hour per day, 7 day per week, to quickly clean up and properly dispose of any leaked materials and 'caning wastes. In case of any significant incident, the Poudre Fire Authority would be called for assistance. Loading and unloading operations will take place in contained areas where any leak or spill wculd be contained and immediately cleaned up. Any gas release would be limited through use of full , me leak detection systems, restricting orifices and properly ventilating to concentrations considered safe according to EPA and OSHA regulations.
