Continuously calculate and record the HAP thermal feed concentration for each constituent by dividing the HAP feedrate determined in paragraph (m)(2)(ii)(A) of this section by the thermal feed rate determined in paragraph (m)(2)(ii)(C) of this section for all hazardous waste feedstreams; §63.1207(m)(2)(ii)(D) Rev. 4/8/2008 FR Interlock the HAP thermal feed concentration for each constituent with the AWFCO to stop hazardous waste feed when the thermal feed concentration exceeds the applicable thermal emission standard. §63.1207(m)(2)(ii)(E) Rev. 4/8/2008 FR When you determine the feedrate of mercury, semivolatile metals, low volatile metals, or total chlorine and chloride for purposes of this provision, except as provided by paragraph (m)(4) of this section, you must assume that the analyte is present at the full detection limit when the feedstream analysis determines that the analyte in not detected in the feedstream. §63.1207(m)(3) Rev. 4/8/2008 FR Owners and operators of hazardous burning cement kilns and lightweight aggregate kilns may assume that mercury is present in raw material at half the detection limit when the raw material feedstream analysis determines that mercury is not detected. §63.1207(m)(4) Rev. 4/8/2008 FR
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)
2.I.7.b.2 For sources exempt from the feedrate limit for total chlorine and chloride under §63.1209(n)(4) because they comply with §63.1207(m)(2), the feedrate limit for total chlorine and chloride to ensure compliance with the annual average emission rate must be established as follows: §63.1215(g)(2)(ii) 2.I.7.b.2.a The source must establish an average period for the feedrate that does not exceed an annual rolling average; §63.1215(g)(2)(ii)(A) 2.I.7.b.2.b The numerical value of the total chlorine and chloride feedrate limit (i.e., not considering the averaging period) must not exceed the value you calculate as the annual average HCl-equivalent emission rate limit (lb/hr) divided by [1 − system removal efficiency], where the system removal efficiency is calculated as prescribed by paragraph (f)(2) of this section. §63.1215(g)(2)(ii)(B) 2.I.7.b.2.c The source must calculate the initial rolling average as though you had selected a 12-hour rolling average, as provided by paragraph (b)(5)(i) of this section. The source must calculate rolling averages thereafter as the average of the available one-minute values enough one-minute values are available to calculate the rolling average period you select. At that time and thereafter, the source updates the rolling average feedrate each hour with a 60-minute average feedrate. §63.1215(g)(2)(ii)(C) 2.I.7.c Feedrate limit to ensure compliance with the average HCl-equivalent emission rate limit. §63.1215(g)(3)
