This Chapter applies to all new and existing facilities where regulated materials subject to this Chapter are present in concentrations which exceed the Level of Concern as determined in accordance with this Chapter. -1- B. In the event of conflicting or overlapping regulatory provisions within this Title, or Title 18 of the Code, and this Chapter, the most stringent requirement shall be applied. C. In the event of conflicting or overlapping regulatory provisions with a federal law or state law or regulation, unless the application of this Ordinance is expressly preempted by an Act of Congress or enactment of the legislature, the more stringent requirement shall apply. 17.07.020 Definitions Generally Unless the context otherwise requires, the words and phrases in this Chapter shall have the meanings set forth in this Part 1 and shall govern the construction of this Chapter. For words and phrases not defined in this Chapter, the definitions set forth in Chapters 17.04, 17.06, 17.08, 17.16, and 17.60 of Title 17 and Title 18 of the Campbell Municipal Code shall control. 17.07.025 Controls "Controls" are means to regulate materials to prevent unauthorized discharges. 17.07.028 Control Area "Control Area" means a space within a building where regulated materials may be stored, handled, dispensed or used. A control area is an area formed by one or more of the following: A. An occupancy separation with a minimum one -hour fire -resistive rating, or B. The exterior wall, roof or foundation of the building. A maximum of four control areas shall be permitted within a building except buildings or portions of buildings used for retail sales, which shall have a maximum of two control areas. -2- 1,7.07.030 Equilibrium Vapor Concentration (EVC) "Equilibrium Vapor Concentration" ("EVC") means the state of a regulated material at which vapor pressure has stabilized and is no longer rising or falling. The EVC value of a regulated material is determined by multiplying vapor pressure ("VP") by 10' and dividing by atmospheric pressure, as shown in the following equation: EVC (ppm) = Vapor Pressure x 106 Atmospheric Pressure 760 mm Hg Note: Vapor pressure for materials with a boiling point equal to or less than 25°C shall be 760 mm Hg; materials with a boiling point greater than 250C shall use the actual vapor pressure for that material at 251C. Atmospheric pressure is assumed to be 760 mm at sea level. 17.07.035 Facility "Facility" means any building, structure, installation, equipment, pipe, container, site, area, appurtenant structure, or surrounding land area where regulated materials are stored, used, dispensed, handled, placed or otherwise have come to be located. 17.07.040 Fire Code "Fire Code" means Title 17 of this Code. 17.07.045 Gas "Gas" means an aeriform fluid which is in a gaseous state at normal temperature and pressure. 17.07.047 IDLH (Immediately Dangerous to Life and Health) "IDLH" (Immediately dangerous to life or health) means a concentration of airborne contaminants, normally expressed in parts per million (ppm) or milligrams per cubic meter, which represents the maximum level from which -3- cane could escape within 30 minutes without any escape impairing symptoms or irreversible health effects.

MHI is determined by dividing the Equilibrium Vapor Concentration (EVC) of a material at 25 degrees Celsius by the Level of Concern for the material, as shown in the following equation: MHI = EVC (ppm) @ 25 degrees Celsius LOC ( ppm ) 17.07.080 Maximum Threshold Quantity (Max T.Q.) "Maximum Threshold Quantity" ("Max.T.Q.") means the maximum quantity of a Class II or Class III regulated material which may be stored in a single vessel before a stricter category of regulation is required by this Chapter.
