On August 23, 1985, the Dublin Planning Director approved Site Development Review to allow the construction of a 13,836 square foot laboratory addition to the existing Hexcel building. On October 10, 1986, the Dublin Planning Director approved Site Development Review for a master identification sign for Hexcel. On October 3, 1988, the Dublin Planning Commission approved a Conditional Use Permit to allow the installation of a 10.79 foot tall, 522 gallon capacity, above ground storage tank for the storage of liquid nitrogen at the existing Hexcel facility. This Conditional Use Permit expired on October 12, 1990. APPLICABLE REGULATIONS: Section 8-51.3(b) of the Dublin Zoning Ordinance states that outside storage of equipment and supplies (if conducted within an area enclosed by a solid wall or fence) in the M-1 Zoning District requires a Conditional Use Permit. Section 8-94.0 states that conditional uses must be analyzed to determine: 1) whether or not the use is required by the public need; 2) whether or not the use will be properly related to other land uses, transportation and service facilities in the vicinity; 3) whether or not the use will materially affect the health or safety of persons residing or working in the vicinity; and 4) whether or not the use will be contrary to the specific intent clauses or performance standards established for the district in which it is located. ENVIRONMENTAL REVIEW: This project has been found to be Categorically Exempt from CEQA under Section 15301, Class 1 of the California Environmental Quality Action guidelines in that the operation involves no expansion of use beyond that previously existing. -2- PAGE OF NOTIFICATION: Public Notice of the February 19, 1991 hearing was published in the local newspaper, mailed to adjacent property owners, and posted in public buildings. ANALYSIS: The Applicant is requesting approval of a Conditional Use Permit to allow the continued operation of a 10.79 foot tall, above ground, Linde VCC-50, 522 gallon capacity, liquid nitrogen storage tank, stored outside the existing Hexcel facility at 11711-11755 Dublin Boulevard. The storage tank provides a readily accessible supply of liquid nitrogen on site, which is used as a pressurizing agent in the manufacturing of advanced materials for the aerospace industry. The existing liquid nitrogen tank has been in operation for approximately two years. During this period, no complaints have been received by the Zoning Investigator or the Police Department regarding this use. The storage tank is in compliance with all applicable regulations of the Zoning Ordinance and the General Plan. This project has been reviewed by other City departments and affected agencies and no objections were stated. Conditions are included in the draft resolution requiring continued compliance with all applicable Fire and Building codes to ensure public safety. Staff recommends approval of the Applicant's request for a Conditional Use Permit, subject to the conditions listed in the draft resolution, Exhibit B. RECOMMENDATIONS: FORMAT: 1) Open public hearing and hear Staff presentation. 2) Take testimony from Applicant and the public. 3) Question Staff, Applicant and the public. 4) Close public hearing and deliberate. 5) Adopt resolution approving PA 90-128, or give Staff and Applicant direction and continue the matter. ACTION: Staff recommends the Planning Commission adopt the attached resolution (Exhibit B) approving the Conditional Use Permit for Hexcel Corporation, PA 90-128.

The Hexcel employees at 11711 Dublin Blvd. conduct research to define new products as well as support existing products. Part of this work requires the processing of Hexcel pregregs into fully cured laminates. This processing is conducted in one of three autoclaves at the research facility. An autoclave is a vessel which can be heated to follow a specified temperature profile and pressurized to follow a specified pressure profile over time. The maximum pressure these autoclaves are taken to is 200 psig. For a number of reasons it is desirable to pressurize these autoclaves using pure nitrogen instead of compressed air. An ideal way to accomplish this is by utilizing an above ground liquid nitrogen storage tank to supply the pressurization. A planning application (PA 88-008) was submitted and subsequently approved on October 14, 1988 for a project to install a liquid nitrogen storage tank at our facility. It involves the installation of a Linde Vcc-50 spherical container, 10.79' tall and has a 522 gallon capacity. The device was put in shortly after the approval and is currently under full operation. To the best of our knowledge, there had been no complaints or problems associated with its usage for the last two years of operation. We hereby request the renewal of the permit to continue maintaining and operating the above said device.

DESCRIPTION The VCC-50 is a spherical container used for stor- age of oxygen, nitrogen, or argon. This container will hold approximately 50,000 cubic feet of oxy- gen at NTP. Most VCC-50's are now used at loca- tions requiring a high pipeline pressure. Table 1 gives specifications and design data for VCC-50's. These units have part number 223036, and serial numbers 101 through 129 inclusive. The control manifold and pressure building coil are included as part of the assembly as shown in Figure 1. The VCC-50 uses the same control manifold as the VCC-100. Refer to Section 9-U, Item 3 for infor- mation on the M-50/M-100 control manifold. The pressure building coil is below the tank only a few inches off the ground as shown in Figure 2. All part numbers given in this write-up are Tonawanda factory numbers unless otherwise noted. INSULATION Before installing a VCC-50, purge all lines with dry nitrogen gas if the VCC-50 was previously used for oxygen service. Use purity tests to determine the oxygen concentration in the tank. If the oxygen concentration is less than 21%, a torch may be used to unsweat the threaded plug in the top of the outer casing to determine if the insulation has settled. Add Perlite to fill voids. Sweat plug in place after adding the required amount of insula- tion. Never add wet or damp insulation. INSTALLATION 1. Shipping Rods — VCC-50 tanks have perma- nently installed shipping rods that do not require adjustment or removal. 2. Tanks Moved by Vehicle — Prior to removing tank from transport vehicle, inspect it for external damage and take a vacuum reading. Compare con- dition of tank at arrival with condition reported at time of shipment so that a claim can be made for damage incurred in transit. 3. Foundation — Refer to "How to Make a Site Survey" manual for dimensions of flat pad. These dimensions must be increased to include any op- tional equipment such as a vaporizer. Install the CONTROL MANIFOLD (See Section 9-U, Item 3) VCC-50 STORAGE TANK PRESSURE BUILDING COIL Figure 1. VCC-50 with Control Manifold storage tank legs on concrete pillars to elevate the tank and its pressure building coil in areas where snow would frequently cover the pressure building coil. A snow covered coil loses efficiency. Raising the VCC-50 tank also makes repair easier: 4. Rigging — Unload and erect tank carefully. In- stall as follows: a. Prepare site for tank installation. b. Arrange for a rigger and crane to be at the site on the scheduled installation date. Make sure the crane can handle a minimum of 3 - 1/2 tons and can easily raise the 7 - 1/2 foot high tank into position. The crane must have a long enough boom to handle and position the tank as required. c. Make sure rigger has adequate chains and slings. d. Be careful not to dent the storage tank.
