A TRUE COPY CERTIFICATION ON LAST PAGE J.R. SMITH, CLERK (e) Enter the Nature of the Hazard in the Physical State and Quantity tab section in the Hazards subtab (acute, chronic, fire, pressure, etc.). See CAMEOfm Chemicals at the top right and click box — look -up "Chemical". 3. Vulnerability Analysis (CAMEOfm Scenario Page) (a) For each Extremely Hazardous Substance (EHS) present over the Threshold Planning Quantity (TPQ), create a New Scenario page (if a Scenario page hasn't been created already) and enter the maximum amount in the largest container or interconnected containers in the Amount Released field of the Scenario Description tab. (b) On the Scenario page(s) Scenario Description tab, enter the concentration percentage in the Concentration field. (c) On the Scenario page(s) Scenario Description tab, enter the release duration in the Release Duration field as follows: (1) Gases —10 minutes (2) Powders or Solids in Solution — 10 minutes (3) Liquids — No value shall be entered (d) Enter the proper natural physical state of the chemical at room temperature in the physical state field (as specified in CAMEOfm Chemicals). (e) On the Scenario page(s) Scenario Description tab, use the weather default settings or, enter average wind speed. Alternate scenarios may also be entered. (f) On the Scenario page(s) Scenario Description tab, rate the Risk, Consequences and Overall Risk of a release occurring at the facility on the bottom of the Scenario Page (the Risk Assessment should be based upon the Extremely Hazardous Substance EHS), previous release history, maintenance conditions etc.). (g) After entering the information noted above on the Scenario Description tab and clicking on the Estimate Threat Zone Radius button, CAMEOfm will automatically estimate the extent of the threat zone that may cause injury or death to human populations following a release. (h) On the Scenario page(s) notes tab, enter an estimate of the total exposed population within the threat zone(s) or link the facility location to a Marplot map where the threat zone population may be estimated based on the most recently available Census data. This image must be available off-line if this alternative method is selected. A map -capture from Marplot may be saved as an alternative method. If using this method upload the map data image to the CAMEOfm Site Plan tab/Facility page and write on the Notes tab/Scenario page where the Total Exposed Population can be found. Add the file name. Example: Total Exposed Population: See Marplot map (name of map SERC#TEP) (i) On the Scenario page(s) notes tab, identify each critical facility by name and maximum expected occupancy within the threat zone(s) (schools, day cares, public safety facilities, hospitals, etc.). If there are no critical facilities within the threat zone(s), that shall be noted. An alternative method is to link the facility location to a Marplot map in which a critical facilities geographic shape filed has been loaded. If using this method upload the map data image to the CAMEOfm Site Plan tab/Facility page and write on the Notes tab/Scenario page where the Critical Facility information can be found. Add the file name. Example: Critical Facilities: See Marplot map (name of map SERC#CF). 22
