Overview• Fugitive Emissions and EO 13514• Common Emission Sources• Calculation Methods– EO 13514 Default and Advanced methodologies– Rolling Averages– Reporting Portal• Leveraging other Reporting Requirements• Moving Forward2Federal Energy Management Programfemp.energy.gov

Fugitive Emissions and EO 13514• EO 13514 requires agencies to report emissions offugitive greenhouse gases (GHG) as part of annual GHGand Sustainability Reports to CEQ/OMB• Fugitive emissions ≡ intentional or unintentional releasesof GHGs from agency operated equipment• Fugitive categories in the EO:– “F-Gas”: Fluorinated Gases (typically refrigerants)– Solid Waste Landfills: Methane (CH 4 ) from decomposition– Wastewater Treatment Facilities: Methane (CH 4 )Federal Energy Management Programfemp.energy.gov

Fugitive Emissions and EO 13514• These gases tend to have high Global Warming Potential– EX: SF 6 has 23,000 times the heat trapping power as CO 2• Identifying and fixing leaks can save $ and have a largeimpact on emissions reductionsFederal Energy Management Programfemp.energy.gov

Common Fugitive Emission Sources• Refrigerants (HFCs and PFCs)• Electrical Transformers (SF 6 )• Fire Suppression Equipment (HFCs)• Wastewater Treatment Plants (CH 4 , N 2 O)• Solid Waste Landfills (CH 4 )• Mission-specific– Munitions Firing (CO 2 )– Laboratory Fume Hoods (HFCs, PFCs, SF 6 )– Medical Imaging Equipment (PFCs)– Wind Tunnels (HFCs)– Particle Accelerators (SF 6 )– Radars (SF 6 )Federal Energy Management Programfemp.energy.gov

F-Gas Calculation MethodsMaterials Balance Approach for F-GasesMaterials Balance Method requires knowledge of inventory change and equipmentcapacity data:Step 1 Determine base inventory for each fugitive source-Storage End=Sum--Step 2 Calculate CO 2 e for each GHG and sum overall emissionsTotal Emissions[Tons of CO 2 e]Global Warming Potential[CO 2 e/F-Gas]= ×Emissions[Tons of F-Gas](From Step 1)Federal Energy Management Programfemp.energy.gov

EO 13514 F-Gas CalculationMethodologiesDefault (in the TSD and Reporting Workbook)– Supply system transaction screening approach– Data from procurement, HMIS or “Hazmat Pharmacy” level– Separates Target/Non-target/InternationalAdvancedPurchased/Issued1. Materials balance approach• At the piece of equipment level2. Simplified materials balance approach• Uses equipment level data to calculate losses from installation,operation, and disposal3. Screening approach-ReturnedSumStorage BeginningPurchasedCapacity Beginning• Uses leak rate factors to estimate losses from installation,operation and disposal---Storage EndDisbursedCapacity EndFederal Energy Management Programfemp.energy.gov

EO 13514 F-Gas CalculationMethodologiesBut what if you don’t have data for default or advancedmethodologies?• No de minimis threshold• But if costs are high or data are not available, agenciesmay justify, document, and report:– Estimation methodologies (ex: based on leak rates for airconditioned square footage)– As a last resort, rational for excluding an emissions source.Federal Energy Management Programfemp.energy.gov

Leveraging Other ReportingRequirementsIt is important to recognize where data collection systems andprocesses may already be in place and available forcollecting GHG data• Under CAA Title VI and the Montreal Protocol, OzoneDepleting Substances (ODS) are being phased out andsubstituted with HFCs and PFCs– HMMS or HM Pharmacy’s may have useful systems in place• Mission specific operations may have uniqueapplications and tracking systems– e.g. Particle accelerators.• CAA Title V permitting process for large emissionsources overlapFederal Energy Management Programfemp.energy.gov

Moving Forward• Reporting fugitives data is new to the FederalGovernment, and will evolve over time.• From CEQ and FEMP, expect:– Evolving Guidance and tools to help agencies improve thequality of annual inventories• Reporting agencies should be striving:– To leverage existing overlapping reporting requirements– Establish data collection systems and procedures to capturethese new data– Coordinate GHG, sustainability, operations, andprocurement management where possible toidentify reductions and reduce costs whenpossibleFederal Energy Management Programfemp.energy.gov
