Title: Example risk management plan and offsite consequence analysis for power plant aging using ammonia and chlorine

This paper provides an example of a risk management plan (RMP) for a utility power plant required under Title III of the 1990 Clean Air Act Amendments (CAAA). Under Title III, certain facilities are required to identify hazards associated with chemicals used to prevent accidental releases, and to minimize consequences of releases. Ammonia is used to reduce nitrogen oxides (NO{sub x}) emissions and is injected in the post-combustion system based on the selective catalyst reduction (SCR) process. Chlorine is used in the potable water treatment process. This paper provides an overview of the elements required in the RMP and specific methods and procedures currently recommended by the EPA for estimating hazardous air pollutant emissions and impacts related to the ammonia and chlorination processes cited in this paper. Information is presented that addresses the potential extent of a pollutant's impacts, including methods and assumptions designed to over-estimate concentrations. Alternative approaches are used to estimate more realistic but still conservative concentrations. Based on the results of these analyses, strategies are recommended that the plant could incorporate to reduce the level of potential impacts and, therefore, program requirements under RMP.
