2. 12/3/2009
Purpose of Presentation on the
Greenhouse Gases Regulation
• Why this new rule?
• Overview of greenhouse gases (GHG)
• Who needs to report GHG emissions
• What is required and by when?
• Provide a couple "industry" examples
2
3. 12/3/2009
What!!! Another Rule? Why?
Per the rule preamble, here are a few reasons:
• Assist US EPA in assessing how to address
GHG emissions and climate change under the
Clean Air Act
• GHG information will help EPA assess how to
address GHG emissions
• Track emission trends
• Improve the U.S. government’s ability to
formulate GHG policy
This rule precedes likely requirement for GHG
Emissions Controls

4. Greenhouse Gas Reporting Rule
• Can I Stop Reporting?
– Basic Premise is Once In Always In
– Exceptions:
• Less than 25,000 Metric Tons CO2e each
year for 5 years
• Less than 15,000 Metric Tons CO2e each
year for 3 years
– Once Threshold Reached, Must Report Again
4
5. 12/3/2009
All right, so you’re stuck. What is
it that has to be done?
Determine the Emissions of GHG Compounds:
Those with Emission Equations/Factors In the Rule
• CO2
• Methane
• Nitrous Oxide (N2O)
Others
• Chlorofluorocarbons
(CFCs)/Hydrofluorocarbons (HFCs)
• A few others listed in Table A-1 of rule
5
6. Global Warming and CO2e
• How Much is 25,000 Metric Tons of CO2e?
– Annual GHG Emissions from Energy Use of
2,300 Homes
– Annual GHG Emissions from 4,600 Cars
• What is a Metric Ton of CO2e?
– The tons of CO2 emissions with the same
global warming potential (GWP) as one ton of
another GHG
• What is Global Warming Potential?
– A measure of how much a given GHG
contributes to global warming
6
7. 12/3/2009
Non-CO2 Greenhouse Gases Have
Global Warming Potentials
Carbon Dioxide Equivalent (CO2e) is the
relative GHG depleting effect of a chemical
as compared to CO2 (where CO2e = 1)
Examples:
• CO2e of methane is 21
• N2O (nitrous oxide) is 310
• CO2e of Sulfur Hexafluoride is 23,900
7
8. Global Warming and CO2e
Examples
– 1 ton of N2O = 310 tons of CO2e
– A facility emits 5,00 tons of CH4 and 100
tons of N2O
• 500 x 21 = 10,500 tons
• 100 x 310 = 31,000 tons
• Total CO2e of Facility is 41,500 tons

How Simple it Can Be: “Other” Facilities Category
Lincoln Electric:
• Euclid Campus – Not in the “Long” or “Short” list of
industries.
o Does have >30 mmBTU/hr aggregate maximum
heat input
o Does emit >25,000 ton CO2e from combined
stationary sources.
• All sources are on a common pipe (1 reading).
• Meter is calibrated by Dominion.
• Gas is tested for high heating value by
Dominion. (Although Lincoln Electric can use
Tier 1 calculation methods –listed emissions
factors– the means are there to use Tier 2,
which is more accurate.)
• Mentor Campus – Under the Threshold. Will not need to
23
report.
