Annual average rates. You must calculate annual average toxicity-weighted HCl-equivalent emission rates for each combustor as follows: §63.1215(b)(2) Where: 2.I.2.b Rev. 4/8/08 FR ERLTtw is the annual average HCl emission rate (HCl-equivalent emission rate) considering long-term exposures, lb/hr ERHCl is the emission rate of HCl in lbs/hr ERCl2 is the emission rate of chlorine in lbs/hr RfCHCl is the reference concentration of HCl RfCCl2 is the reference concentration of chlorine 1-hour average You must calculate average toxicity-weighted HCl-equivalent emission rates for each combustor as follows: §63.1215(b)(3) Where: 2.I.2.c Rev. 4/8/08 FR ERSTtw is the 1-hour average HCl-toxicity-weighted emission rate (HCl-equivalent emission rate) considering 1-hour (short-term) exposures, lb/hr ERHCl is the emission rate of HCl in lbs/hr ERCl2 is the emission rate of chlorine in lbs/hr aRELHCl is the aREL for HCl aRELCl2 is the aREL for chlorine The source must use the RfC values for hydrogen 2.I.2.d §63.1215(b)(4) chloride and chlorine found at . The source must use the aREL values for 2.I.2.e §63.1215(b)(5) hydrogen chloride and chlorine found at
2.I.2.b Annual average rates. You must calculate annual average toxicity-weighted HCl-equivalent emission rates for each combustor as follows: Where: ERLTtw is the annual average HCl emission rate (HCl-equivalent emission rate) considering long-term exposures, lb/hr ERHCl is the emission rate of HCl in lbs/hr ERCl2 is the emission rate of chlorine in lbs/hr RfCHCl is the reference concentration of HCl RfCCl2 is the reference concentration of chlorine §63.1215(b)(2) Rev. 4/8/08 FR 2.I.2.c 1-hour average You must calculate average toxicity-weighted HCl-equivalent emission rates for each combustor as follows: Where: ERSTtw is the 1-hour average HCl-toxicity-weighted emission rate (HCl-equivalent emission rate) considering 1-hour (short-term) exposures, lb/hr ERHCl is the emission rate of HCl in lbs/hr ERCl2 is the emission rate of chlorine in lbs/hr aRELHCl is the aREL for HCl aRELCl2 is the aREL for chlorine §63.1215(b)(3) Rev. 4/8/08 FR 2.I.2.d The source must use the RfC values for hydrogen chloride and chlorine found at . §63.1215(b)(4) 2.I.2.e The source must use the aREL values for hydrogen chloride and chlorine found at §63.1215(b)(5)
