Greenhouse Gas Reporting Program
Applicability Tool (version with current GWPs)
Does your facility have any of the source categories/segments listed below?
Instructions. In the list below, select each source category/segment located at your facility by clicking the checkbox. For a definition of the source category/segment, click on the name of the source category/segment or use the glossary of terms link at the bottom of the page.
Note. The reporting rule applies at the facility level and not the corporate level. As a result, an owner or operator must assess applicability separately for each facility in the United States. The tool will use information that you enter to assess applicability, but the information is not stored. Therefore, users are advised to enter facility information below. Information provided will appear on your results page for you to print/save for your records.
Does your facility also have stationary fuel combustion? 
Do your facility operations also involve miscellaneous uses of carbonate?
Important Consideration. Subpart W industry segments may be co-located or operate dual purpose equipment. For the purposes of determining applicability, please select all applicable source categories/segments for your assessment. 
Important Consideration. The miscellaneous uses of carbonates source category includes facilities only if they consume at least 2,000 tons per year of carbonates heated to a temperature sufficient to allow the calcination reaction to occur.
This source category does not include equipment that uses carbonates or carbonate containing minerals that are consumed in the production of cement, glass, ferroalloys, iron and steel, lead, lime, phosphoric acid, pulp and paper, soda ash, sodium hydroxide, or zinc.
Do you still want to select miscellaneous uses of carbonates as a source category?
Important Consideration. For facilities that contain only stationary fuel combustion sources and miscellaneous uses of carbonates, emissions from the miscellaneous use of carbonates are not considered for determining applicability or reporting.
Important Consideration. The electricity generation source category comprises electricity generating units that are subject to the requirements of the Acid Rain Program and any other electricity generating units that are required to monitor and report to EPA CO2 emissions year-round according to 40 CFR part 75.
This source category does not include portable equipment, emergency equipment, or emergency generators, as defined in §98.6. Do you want to keep this source category checked for your assessment?
Important Consideration. This source category should be assessed if not co-located with an HCFC-22 production facility and it destroys more than 2.14 metric tons of HFC-23 per year.
Do you want to keep this source category checked for your assessment?
Important Consideration. The underground coal mine source category comprises underground coal mines subject to quarterly or more frequent sampling of ventilation systems by the Mine Safety & Health Administration (MSHA).
Do you want to keep this source category checked for your assessment?
EPA will not be implementing subpart JJ of the Mandatory GHG Reporting Rule due to a Congressional restriction prohibiting the expenditure of funds for this purpose.
Important Consideration. The industrial wastewater treatment source category only applies to industrial wastewater and industrial wastewater treatment sludge co-located with one or more of the following processes:
pulp and paper manufacturing, food processing, ethanol production, petroleum refining
Do you want to keep this source category checked for your assessment?
Important Consideration. Does the electrical equipment manufacturing and refurbishing facility have total annual purchases of SF6 and PFCs that exceed 23,000 pounds?
Important Consideration. Part 98 treats electrical transmission and distribution equipment use as an independent facility (see definition below). If your electrical transmission and distribution equipment use facility is co-located with any GHG-emitting equipment on the pick list, you must conduct an assessment to determine applicability for the electrical transmission and distribution equipment use facility, and the other GHG-emitting equipment would be assessed as a separate facility as defined in Section 98.6 of Subpart A.
Facility, with respect to an electric power system, means the electric power system as defined in this paragraph. An electric power system is comprised of all electric transmission and distribution equipment insulated with or containing SF6 or PFCs that is linked through electric power transmission or distribution lines and functions as an integrated unit, that is owned, serviced, or maintained by a single electric power transmission or distribution entity (or multiple entities with a common owner), and that is located between: (1) the point(s) at which electric energy is obtained from an electricity generating unit or a different electric power transmission or distribution entity that does not have a common owner, and (2) the point(s) at which any customer or another electric power transmission or distribution entity that does not have a common owner receives the electric energy. The facility also includes servicing inventory for such equipment that contains SF6 or PFCs.
Do you want to keep this source category checked for your assessment? (If "Yes," your other pick-list selections will be deselected and will need to be assessed separately.)
Important Consideration. Part 98 treats natural gas distribution as an independent facility (see definition below). Therefore, if you own or operate a natural gas distribution system and other GHG-emitting equipment on the pick list (except Stationary Fuel Combustion sources, which are included under subpart W, not subpart C), you must conduct an assessment to determine applicability for the natural gas distribution facility as defined below. The other GHG-emitting equipment would be assessed as a separate facility as defined in Section 98.6 of Subpart A.
Facility with respect to natural gas distribution for purposes of reporting under this subpart and for the corresponding subpart A requirements means the collection of all distribution pipelines and metering-regulating stations that are operated by a Local Distribution Company (LDC) within a single state that is regulated as a separate operating company by a public utility commission or that are operated as an independent municipally-owned distribution system.
Do you want to keep this source category checked for your assessment? (If "Yes," your other pick-list selections will be deselected and will need to be assessed separately.)
Important Consideration. Part 98 treats onshore petroleum and natural gas production as an independent facility (see definition below). Therefore, if you own or operate onshore petroleum and natural gas production equipment that is co-located with any GHG-emitting equipment on the pick list (except Stationary Fuel Combustion sources, which are included under subpart W, not subpart C), you must conduct an assessment to determine applicability for the onshore petroleum and natural gas production facility, as defined below. The other GHG-emitting equipment would be assessed as a separate facility, as defined in Section 98.6 of Subpart A.
Facility with respect to onshore petroleum and natural gas production for purposes of reporting under this subpart and for the corresponding subpart A requirements means all petroleum or natural gas equipment on a single well-pad or associated with a single well-pad and CO2 enhanced oil recovery operations that are under common ownership or common control including leased, rented, or contracted activities by an onshore petroleum and natural gas production owner or operator and that are located in a single hydrocarbon basin as defined in §98.238. Where a person or entity owns or operates more than one well in a basin, then all onshore petroleum and natural gas production equipment associated with all wells that the person or entity owns or operates in the basin would be considered one facility.
Do you want to keep this source category checked for your assessment? (If "Yes," your other pick-list selections will be deselected and will need to be assessed separately.)
Important Consideration. Offshore petroleum and natural gas production includes only the equipment located on the platform. If you continue with offshore petroleum and natural gas production as a source category (an industry segment under the subpart W source category), the applicability tool will automatically include stationary fuel combustion as a selected source category for entering your estimated GHG emissions.
Do you want to keep offshore petroleum and natural gas production checked for your assessment?
Important Consideration. Part 98 treats onshore natural gas transmission pipelines as an independent facility (see definition below). Therefore, if you own or operate an onshore natural gas transmission pipeline facility that is co-located with any other GHG-emitting equipment on the pick list, you must conduct an assessment to determine applicability for the onshore natural gas transmission pipeline facility, as defined below. The other GHG-emitting equipment would be assessed as a separate facility, as defined in Section 98.6 of Subpart A.
Facility with respect to the onshore natural gas transmission pipeline segment means the total U.S. mileage of natural gas transmission pipelines, as defined in section 98.238, owned and operated by an onshore natural gas transmission pipeline owner or operator as defined in section 98.238. The facility does not include pipelines that are part of any other industry segment defined in this subpart.
Onshore natural gas transmission pipeline owner or operator means, for interstate pipelines, the person identified as the transmission pipeline owner or operator on the Certificate of Public Convenience and Necessity issued under 15 U.S.C. 717f, or, for intrastate pipelines, the person identified as the owner or operator on the transmission pipeline's Statement of Operating Conditions under section 311 of the Natural Gas Policy Act (NGPA), or for pipelines that fall under the "Hinshaw Exemption" as referenced in section 1(c) of the Natural Gas Act, 15 U.S.C. 717-717 (w)(1994), the person identified as the owner or operator on blanket certificates issued under 18 CFR 284.224. If an intrastate pipeline is not subject to section 311 of the NGPA, the onshore natural gas transmission pipeline owner or operator is the person identified as the owner or operator on reports to the state regulatory body regulating rates and charges for the sale of natural gas to consumers.
Do you want to keep this source category checked for your assessment? (If "Yes," your other pick-list selections will be deselected and will need to be assessed separately.)
Important Consideration. Part 98 treats onshore petroleum and natural gas gathering and boosting as an independent facility (see definition below). Therefore, if you own or operate onshore petroleum and natural gas gathering and boosting equipment that is co-located with any GHG-emitting equipment on the pick list (except Stationary Fuel Combustion sources, which are included under subpart W, not subpart C), you must conduct an assessment to determine applicability for the onshore petroleum and natural gas gathering and boosting facility, as defined below. The other GHG-emitting equipment would be assessed as a separate facility, as defined in Section 98.6 of Subpart A.
Facility with respect to onshore petroleum and natural gas gathering and boosting for purposes of reporting under this subpart and for the corresponding subpart A requirements means all gathering pipelines and other equipment located along those pipelines that are under common ownership or common control by a gathering and boosting system owner or operator and that are located in a single hydrocarbon basin as defined in section 98.238. Where a person owns or operates more than one gathering and boosting system in a basin (for example, separate gathering lines that are not connected), then all gathering and boosting equipment that the person owns or operates in the basin would be considered one facility. Any gathering and boosting equipment that is associated with a single gathering and boosting system, including leased, rented, or contracted activities, is considered to be under common control of the owner or operator of the gathering and boosting system that contains the pipeline. The facility does not include equipment and pipelines that are part of any other industry segment defined in this subpart.
