(b) Maximum quantity on-site <br />Express in exact pounds (not range codes) the maximum quantity of <br />each Extremely Hazardous Substance the facility has on-site at any time <br />up to one year prior to the site visit. <br />(c) Amount in largest container or interconnected containers <br />Express in pounds the amount of each Extremely Hazardous Substance <br />stored in the largest container or interconnected containers (this is the <br />release amount used to determine the Vulnerable Zone). <br />(d) Type and design of storage container or vessel <br />Indicate the storage method of each Extremely Hazardous Substance, <br />i.e., drum, cylinder, tank, and their respective capacities (it is helpful to <br />indicate system types such as manifold versus vacuum as well). <br />(e) Nature of the hazard <br />Describe the type of hazard (i.e., fire, explosion) and health effects <br />(acute and chronic) most likely to accompany a spill or release of each <br />Extremely Hazardous Substance. <br />(3) Vulnerability Analysis <br />(a) Extent of the Vulnerable Zone <br />For each Extremely Hazardous Substance present at a facility, provide <br />the estimated geographical area (vulnerable zone) that may be subject to <br />concentrations of an airborne Extremely Hazardous Substance at levels <br />that could cause irreversible acute health effects or death to human <br />populations following an accidental release. <br />(b) Estimate Facility Population <br />Provide an estimate of the maximum number of employees present at <br />the facility at any given time, i.e. if the facility is unmanned except for <br />routine maintenance by only one person then, the number of employees <br />present at any given time shall be noted as one. <br />(c) Critical Facilities <br />Identify each critical facility by name and each critical facility's maximum <br />expected occupancy, within each vulnerable zone, which are essential to <br />emergency response or house special needs populations (schools, day <br />cares, public safety facilities, hospitals, etc.). If there are no critical <br />facilities within the vulnerable zone, that shall be noted. <br />(d) Estimate Total Exposed Population <br />Provide an estimate of the total exposed population (facility employees + general <br />population + critical facilities), within each vulnerable zone, that would be affected <br />in a worst case release scenario. <br />15 <br />
