| 849 | Q849 | Subpart Q | What is the equation to calculate CO2 emissions from an electric arc furnace (Equation Q-5) for Iron and Steel Production facilities (Subpart Q)? |
| 850 | Q850 | Subpart NN | For local distribution companies (LDCs) how are the subpart NN end-use categories for residential, commercial and industrial consumers and electricity generating facilities defined? How do those definitions compare with those on the Energy Information Administration’s Form EIA-176?

| 851 | Q851 | Subpart C | My aggregation of units/common pipe configuration only contains a few units with a maximum rated heat input capacity ≥ 10 million British thermal units per hour (mmbtu/hr). What should be entered for cumulative maximum rated heat input capacity of the aggregated units? If I only enter the heat input capacity for those units ≥ 10, I receive a data validation error regarding potential-to-emit. |

| 855 | Q855 | Subpart HH | How does a user create fDest in e-GGRT such that it appears on the page “LANDFILL GAS MEASURMENT LOCATIONS” with the user’s desired fractional value? |
| 856 | Q856 | Subpart W | Are unintentional natural gas releases such as those resulting from accidental releases from transmission pipelines or well blowouts subject to reporting under the Greenhouse Gas Reporting Program (GHGRP)? |

| 858 | Q858 | Subpart W | Under Calculation Method 2 for pneumatic devices, which is an available option beginning with Reporting Year 2024, must a device that is zero bleed except for actuation during emergencies and other unintended events (e.g., a wellhead emergency shutdown device) be forced to actuate in order to measure the emissions? |
| 859 | Q859 | Subpart W | Are visual inspections still required for thief hatches if a visual inspection is unsafe to perform due to the contents of the storage tank? |
| 860 | Q860 | Subpart W | Can EPA clarify which liquid throughput quantities in 40 CFR 98.236(aa) are required to be measured via flow meters? |
