2. EPA’s Proposed Mandatory Greenhouse Gas Reporting Rule Technical Considerations Presented to Louisiana Section Air & Waste Management Association September 24, 2009

3. 05M052007D_13 01.15.09 Introduction Proposed April 10, 2009 Signed by Lisa Jackson September 22, 2009 Must be published in Federal Register by End of October (Mid October Likely) From the Press Release: –“This is a major step forward in our effort to address the greenhouse gases polluting our skies,” said EPA Administrator Lisa P. Jackson. “For the first time, we begin collecting data from the largest facilities in this country, ones that account for approximately 85 percent of the total U.S. emissions. The American public, and industry itself, will finally gain critically important knowledge and with this information we can determine how best to reduce those emissions.”

4. 05M052007D_13 01.15.09 Introduction Pollutants (Depending on Subpart) –Carbon Dioxide (CO 2 ) –Methane (CH 4 ) –Nitrous Oxide (N 2 O) –Sulfur Hexafluoride (SF 6 ) –Hydrofluorocarbons (HFCs) –Perfluorochemicals (PFCs) –Other Fluorinated Gases Sources –Listed Sources –Downstream facilities > 25,000 metric tons CO 2 e per year –Upstream suppliers of fossil fuels and industrial GHGs –Manufacturers of vehicles and engines 10,000 Facilities, 85% of GHG Emissions Data Collection – January 1, 2010; First Report – March 31, 2011

5. 05M052007D_13 01.15.09 Purpose “One specific action EPA has taken, consistent with the Congressional request contained in the FY2008 Consolidated Appropriations Act, to collect GHG emissions data.” Under Authority of CAA, but expected to be useful to inform other policy decisions as well. –“The mandatory GHG reporting program will provide EPA, other government agencies, and outside stakeholders with economy-wide data on facility-level (and in some cases corporate-level) GHG emissions, which should assist in future policy development.” “Emissions from direct emitters should inform decisions about whether and how to use CAA section 111 to establish new source performance standards (NSPS) for various source categories emitting GHGs, including whether there are any additional categories of sources that should be listed under CAA section 111(b).”

6. 05M052007D_13 01.15.09 Comments to Proposed Rule 16,800 comments received, Over 15,000 from Sierra Club mass mailer, 45 states, 3 tribal groups, ~16 NGOs, 400 trade groups, 150 individuals Deadline not feasible Allow use of best available information for some transition period Adopt a 5% de minimis level to allow facilities to exclude small sources Not “once in, always in” but allow a facility to drop out of the program if emissions drop below applicability thresholds or equipment is permanently shut down Use other data reported to other government agencies (Department of Energy, Customs and Border Protection) to reduce redundant reporting and protect CBI Use typical fugitive emissions definition and estimation methods Revise certification language Use facility level reporting, rather than unit level No third party verification, or Yes, third party verification to prepare for Cap and Trade Biennial calculations and reporting Supplier reporting performed at company level

7. 05M052007D_13 01.15.09 EPA’s Frequently Mentioned Comments CommentIndustryStatesNGOs Verification General Support of EPA Verification Concerns over CBI Verification Consultants are a well established industry and support 3 rd party Some, but not all, support 3 rd party Interest in roles as auditing function either before or after submittal to EPA Neutral or supportive or EPA verification for transparency purposes CBI Concern that many data elements are CBI Support transparency and complete release of reported data Once in, Always in Support for mechanism to stop reporting if below applicability; disincentive to reduce emissions NA Support for consistent, long- term data set From EPA’s GHG Mandatory Reporting Rulemaking, Katherine Sibold, US EPA Climate Change Division, September 1, 2009

8. 05M052007D_13 01.15.09 Major Issues Third Party Verification – No, EPA will verify. Best Available Information: January 1, 2010 to March 31, 2010 – extension available for remainder of 2010 – application within 30 days of effective date of the rule. Certification Statement: “I certify under penalty of law that I have personally examined, and am familiar with, the statements and information submitted in this document and all its attachments. Based on my inquiry of those individuals with primary responsibility for obtaining the information, I certify that the statements and information are to the best of my knowledge and belief true, accurate, and complete.” Reasonable Inquiry?

9. 05M052007D_13 01.15.09 Major Issues (cont.) Less than 25,000 metric tons CO 2 e for 5 years or less than 15,000 metric tons CO 2 e for three years, or shut- down of all GHG units can discontinue reporting. Accuracy – Meters must be calibrated prior to April 1, 2010 according to the manufacturer’s recommended procedures, an appropriate industry consensus standard, or a method specified in a relevant subpart of this part. All measurement devices shall be calibrated to an accuracy of 5 percent. Lawsuit or Stay? Petition for Judicial Review?

11. 05M052007D_13 01.15.09 Subpart C General Stationary Fuel Combustion Four-tiered Approach - CO 2 TierCovered UnitsCalculation Methodology Tier 1 Units less than 250 MMBtu/hr provided no specific fuel information available; If you have specific HHV info go to Tier 2 Use fuel-specific default CO 2 emission factor, default high heating value, and annual fuel consumption (Nat Gas @ 1027 MMBtu/scf and 53.02 kgCO 2 /MMBtu). Tier 2 Units less than 250 MMBtu/hr for fuels listed in Table C-1 or Units greater than 250 MMBtu/hr for pipeline quality natural gas and distillate fuel oil Use measured high heat values with default CO 2 emission factor and annual fuel combusted (HHV sampling frequency specified by fuel). Tier 3 Any unit greater than 250 MMBtu/hr unless it qualifies for Tiers 1 or 2 or Tier 4 is required Use measured fuel carbon content and quantity combusted.

12. 05M052007D_13 01.15.09 Subpart C General Stationary Fuel Combustion TierCovered Units Calculation Methodology Tier 4 Meets following 6 conditions: Units greater than 250 MMBtu/hr or Combusts more than 250 tpd MSW; Combusts solid fossil fuel as primary or secondary fuel; Operates more than 1000 hours per calendar year; The unit has a CEMS; The CEMS has a certified gas monitor of any kind, or a flow rate monitor, or both; Monitors are required by permit or regulation to undergo QA testing. Units less than 250 MMBtu/hr or Combusts less than 250 tpd MSW if: Unit has both CO 2 concentration monitor and flow monitor; Meets the other requirements above. Starts January 1, 2011 if existing equipment does not meet requirements. Use Tier 2 or 3 for 2010. CEMS

13. 05M052007D_13 01.15.09 Subpart C General Stationary Fuel Combustion Tier 3 Gaseous Fuel Data and Calculation Fuel = Annual SCF, measured directly from calibrated meters CC = Annual average carbon content from sampling MW = Annual average MW from sampling There are still some errors and typos in the procedures.

14. 05M052007D_13 01.15.09 General Stationary Fuel Combustion CH 4 and N 2 O emissions are required only if you had to calculate CO 2 and fuels are listed in Table C-2. Basically use same flow and heating value data you used for CO 2 but apply CH 4 and N 2 O emission factors from Table C-2. Very prescriptive, so map out your plan! Includes provisions for controls and biogenic fuels. Monitoring, QA/QC, Missing Data procedures are stipulated. Reporting includes unit level data such as Unit ID, Type of Unit, Max Heat Input, type of fuel combusted, emissions from each type of fuel combusted as well as CO 2 e, and method used. Significant verification data is required, e.g., monthly heat values for Tier 2. Very prescriptive, so map out your plan!
