This comprehensive paper sought to evaluate two county emergency response plans to determine the implications of their plan quality for Central Plains Ag Services, a North Dakota agricultural business, that handles hazardous chemicals. The planning research literature was reviewed to identify what steps are taken in the planning process, the characteristics that impact plan quality, the importance of participation in planning, and the recommended plan content for all plans regardless of type and response plans specifically. The basic evaluation characteristics for plan quality were identified and these items, along with recommended content were put into an evaluation form. This evaluation form was used to evaluate the two county response plans and the findings of each evaluation were discussed. The implications of the findings for Central Plains Ag Services were discussed and recommendations were made to improve county plans.
