Subpart D requires the entry of the total heat input for each fuel type listed in Table C-2 combusted in each unit (except as otherwise provided in 98.33(c)(4)(ii)(B)) in units of mmBtu. Enter this value in the text box provided in the EQUATION C-10 SUMMARY AND RESULTS section. [98.36(d)(1)(iv)] e-GGRT will calculate CH4 and N2O emissions from the total heat input entered using Equation C-10 and display the results under ANNUAL CH4 EMISSIONS and ANNUAL N2O EMISSIONS, respectively. [98.36(d)(1)(iii)] If you calculated CH4 and N2O emissions for a blended fuel according to 98.33(c)(6)(ii), you can override the automatically calculated emissions values by selecting the "Enter my own result (value will be rounded)" radio buttons under ANNUAL CH4 EMISSIONS and ANNUAL N2O EMISSIONS. Enter the CH4 and N2O values you calculated in the "Report this value" fields.
