Summary Information for this Facility

Subpart P requires you to report the following data about your facility:

• The annual quantity of carbon, other than CO₂, collected and transferred off site in either gas, liquid or solid form (in kg carbon)

Process Unit Information

The required process unit information and the manner by which required process unit information is entered into e-GGRT is different for units that are monitored by a Continuous Emissions Monitoring System (CEMS) and units that are NOT monitored by a CEMS

As a result, separate help content has been created in this subpart for entering process unit information for units monitored by CEMS and units NOT monitored by CEMS

For each process unit that is NOT monitored by CEMS at your facility, the following process unit information is required:

• A unique name or identifier for the unit, plus optional description for this unit (see also About Unique Unit Names) [98.166(b)(1)]
• The quantity of hydrogen produced (in metric tons) [98.166(b)(3)]
• The quantity of ammonia produced (in metric tons) [98.166(b)(4)]
• The quantity of methanol produced, if not reported under subpart X (in metric tons [98.166(e)]*
• The name and type (solid, liquid, or gaseous) of each fuel or feedstock consumed in the unit [98.166(b)(7)]
• The annual quantity of each fuel or feedstock consumed in the unit [98.166(b)(7)]*

*Required for RY2014 and later only

Emissions information for process units NOT monitored by CEMS for RY2014 and later must be entered into the Inputs Verifier Tool (IVT), which is accessed from the Subpart P Summary Page. The user enters equation inputs into the IVT and e-GGRT calculates emissions; however, these equation inputs are not stored by EPA. See Subpart P Entering Equation Inputs Using IVT.

For each process unit that is monitored by CEMS at your facility, the following process unit information is required:

• A unique name or identifier for the unit, plus optional description for this unit (see also About Unique Unit Names) [98.166(a)(1)]
• The quantity of hydrogen produced (in metric tons) [98.166(a)(2)]
• The quantity of ammonia produced (in metric tons) [98.166(a)(3)]
• The quantity of methanol produced, if not reported under subpart X (in metric tons) [98.166(e)]*

*Required for RY2014 and later only

Emissions Information

The required emissions information and the manner by which required emissions information is entered into e-GGRT is different for units that are monitored by a CEMS and units that are NOT monitored by a CEMS

As a result, separate help content has been created in this subpart for entering emissions information for units monitored by CEMS and units NOT monitored by CEMS

For each process unit that is NOT monitored by CEMS at your facility, the following emissions information is required:

• The total annual CO₂ emissions from each hydrogen production process unit (in metric tons)
• Substitute data information for each fuel or feedstock used in each process unit:
  • An indication if the monthly consumption is based on one or more substitute data values
  • An indication if the monthly carbon content is based on one or more substitute data values
  • An indication if the monthly molecular weight is based on one or more substitute data values (applies to gaseous feedstocks only)

For each CEMS Monitoring Location (CML), provide the following information:

• A unique unit name or identifier for the CML (see also About Unique Unit Names)
• An optional description or label for the CML
• The configuration of processes or process units that are monitored by the CML:
  • Single process or process unit that exhausts to a dedicated stack
  • Multiple processes or process units that share a common stack
  • Process or process unit that shares a common stack with one or more stationary fuel combustion units
• The types of fuel combusted in the unit(s) monitored by the CEMS
• The Tier 4/CEMS methodology start and end dates
• The cumulative total of hourly CO₂ mass emissions for each quarter of the reporting year (metric tons) (Do not cumulate emissions data between quarters). These emissions do not include slipstream emissions.
• The total annual CO₂ mass emissions measured by the CEMS (metric tons) (This is the sum of the four quarterly totals). These emissions include slipstream emissions.
• An indication whether emissions reported for the CEMS include emissions calculated according to 98.33(a)(4)(viii) for a slipstream that bypassed the CEMS. Slipstream emissions should be added only to the total annual CO₂ mass emissions measured by the CEMS.
• The total annual biogenic CO₂ emissions from the combustion of all biomass fuels combined (metric tons) (if not applicable, enter '0'). These emissions do not include slipstream emissions.
• The total annual non-biogenic CO₂ emissions, which includes fossil fuel, sorbent, and process CO₂ emissions (metric tons). These emissions do not include slipstream emissions.
• The total annual CH₄ and N₂O emissions associated with the combustion of all Table C-2 fuels combusted in all processes/process units monitored by the CEMS, derived from application of Equation C-10 (metric tons) (if there are no combustion emissions in this CML, please enter '0')
• The total number of source operating hours in the reporting year
• The total operating hours in which a substitute data value was used in the emissions calculations for the CO₂ concentration parameter
• The total operating hours in which a substitute data value was used in the emissions calculations for the stack gas flow rate parameter
• If moisture correction is required and a continuous moisture monitor is used, the total operating hours in which a substitute data value was used in the emissions calculations for the stack gas moisture content parameter

Validation Report

The Validation Report assists you with determining the completeness and quality of your reported data.

We strongly encourage you to use the Validation Report to check your work. The Validation Report performs two types of checks:

• Data Completeness: Data required for reporting that are missing or incomplete.
• Data Quality: Data that are outside of the expected range of values.

Certain validation checks which are considered to represent critical errors must be corrected before you can successfully generate and submit your Annual Report. These checks are signified with a stop sign . If you feel that you have triggered one of these critical “stop signs” checks in error, or if there’s a reason why your report should be submitted despite the check being triggered, please submit a request to the e-GGRT Help Desk at GHGReporting@epa.gov.

You may view the Validation Report at any time.
