1.  Facility Policy. 
 
    The owners, management, and employees of Iowa Double Circle (Mt. Pleasant) are 
    committed to the prevention of any accidental releases of propane.  If an accidental 
    release should occur, the facility is prepared to work with the local fire department, or 
    other authorities, to mitigate and minimize the impacts of the release to the people and 
    the environment. 
 
2.  Facility Information. 
 
    The primary activity at the facility is the storage and delivery of propane for customer use. 
    The maximum quantity stored would be 50,300 pounds of propane. 
 
3.  Worst-Case Senario and Alternate Release Scenario 
 
    a.     The worst-case scenario would be the release of the total contents of a storage 
             tank released as gas over a period of 10 minutes.  The maximum quanity released 
 
       would be 50,300 pounds, which represents the volume of the largest storage tank 
             at 85 percent capacity as limited by design standards.  The distance to the end 
             point (point of dispersion to 200 parts per million, or ppm) is 0.3 miles. 
 
    b.      The alternate release scenario, based on the five-year accident history (or the most 
              likely potential incident), is a release from hose rupture caused by a pull-away 
              and assumes a 25-foot length of 4-inch transfer hose.  The active mitigation 
              devices are assumed to function as designed, limiting the release to the contents 
              of the hose.  The maximum quantitiy released would be 69 pounds.  The distance 
              to the end point (point of 1 psi overpressure) is 0.03 miles, or 175 feet. 
 
4.  Accidental Release Prevention Program 
 
    The facility has been reviewed for general compliance with the provisions of "Safety 
    Requirements for the S 
torage and Handling of Anhydrous Ammonia, K-61.1", published 
    by The American National Standards Institute, Inc. (ANSI), and the Standards of the U.S. 
    Occupational Safety and Health Administration (OSHA), 29 CFR 1910.111, "Storage and 
    Handling of anhydrous ammonia.  The applicable standard for propane is NFPA-58. 
    The OSHA standard is referenced in the Registration Form Section 8.3.b. 
 
5.  There have been no accidental releases of propane in the past five years that have caused 
    any deaths, injuries, or significant property damage at the facility; nor to our knowledge 
    have resulted in off-site deaths, injuries, evacuations, sheltering in place, property 
    damage, or environmental damage. 
 
6.  Emergency Response Program. 
 
    The facility has: 
 
    a.     a written action plan, in accordance with OSHA standard CFR 1910.38; 
 
    b.     provided state and local authorities with the emergency planning and community 
            right-to-know information as  
required under SARA Title III (EPCRA). 
 
7.  Planned Changes to Improve Safety. 
 
    Safety improvement is an on-going process at the facility.  Periodic evaluations are 
    performed to assess the maintenance of safe conditions.  There are no additional specific 
    safety recommendations regarding storage or use of propane for implementation at this 
    time.
