A recent amendment to the EPA’s Mandatory Reporting of Greenhouse Gases Rule (40 CFR part 98) requires companies that report their emissions to also provide information on corporate ownership,  North American Industry Classification System (NAICS) codes, and whether any of the emissions come from a cogeneration unit. The goal behind collecting this information is to gain a better understanding of the aggregate greenhouse gas (GHG) emissions from corporations and specific industry sectors, and identify potential differences in emissions between otherwise similar facilities due to cogeneration. Such information can be used to guide future GHG regulations and mitigation strategies. The rule was signed by Administrator Jackson last week and is to be published the Federal Register shortly. 

The final rule requires facilities and suppliers reporting GHG emissions (large industrial facilities that emit 25,000 metric tons or more per year, plus suppliers of fossil fuels and industrial gases, and a few others) to include, in their first annual GHG emission report due on March 31, 2011,  the name and address of each US parent company and a breakdown of the percentage share that each parent owns. It also requires the facilities to report any NAICS codes that apply to the facility – both the primary code as well as any others that are appropriate.

The third requirement takes the form of a checkbox indicating whether the report includes emissions from a cogeneration unit, defined by EPA as “a unit that produces electrical energy and useful thermal energy for industrial, commercial, or heating or cooling purposes, through the sequential or simultaneous use of the original fuel energy.”  In the final rule, EPA notes that there are no current programs that require facilities to identify whether they have cogeneration units – EPA’s Combined Heat and Power Partnership is only a voluntary program, and while the Energy Information Administration collects information on cogeneration from power generators greater than 1 megawatt, this program likely does not cover all of the facilities and suppliers subject to 40 CFR part 98.

The information collected on cogeneration through this rule is just a start, and useful primarily to merely identify the facilities using cogeneration. As EPA correctly notes, the information likely will not be sufficient to determine the quantity of GHG emissions occurring from particular NAICS sectors or cogeneration units within an individual reporting facility, or the degree to which cogeneration emissions at the applicable facilities displace onsite use of fossil fuel or other emissions from centralized electric generation. Nonetheless, information on the types and characteristics of facilities that use cogeneration could be important to the future development of GHG mitigation strategies.

When we blogged about the Mandatory Greenhouse Gas Reporting Program regulations last fall, we noted that the EPA had excluded from the final regulations emission source categories such as wastewater treatment plants and underground coal mines that were initially included in the draft rules.  No longer. Yesterday, EPA finalized regulations requiring an estimated 680 facilities in the four sectors of underground coal mines, industrial wastewater treatment systems, industrial waste landfills and magnesium production facilities to begin collecting emissions data on January 1, 2011, and submit their first annual report in March 2012. Despite being few in number, these facilities, which primarily emit methane, are responsible for about 1% of national greenhouse gas emissions.  As in the existing reporting rules, 40 CFR Part 98, these businesses are required to report their emissions to EPA if they emit 25,000 metric tons CO₂ equivalents or more per year.  

The final rule also clarifies EPA’s decisions on the remaining categories: EPA will exclude ethanol production and food processing from distinct subparts requiring reporting, as well as suppliers of coal (at least for now).  However, these types of facilities are still required to report emissions under other subparts of the rule, if they meet the reporting threshold of 25,000 metric tons CO_2e per year. In addition, now that EPA has made final decisions on "all outstanding source categories and subparts" from last year's draft rule, additional sectors can only be added through new rulemaking.

EPA also released proposed rules reflecting what data submitted by facilities under the greenhouse gas reporting program will be released to the public and what will be withheld as confidential business information. EPA hopes to have these rules in place before the 10,000 facilities that produce about 85% of the nation’s emissions submit their first reports in March 2011. 

As you may recall, the greenhouse gas reporting rules require both direct emitters and suppliers of fuels and industrial gases to report.   For the “direct emitters,” EPA proposes to release information such as the facility name and physical address, emissions, methodology and data used to calculate the emissions, and test and calibration methods, but withhold as confidential business information data on production, throughput, or raw materials that are not inputs to the emissions equations. As the emissions reported by the suppliers of fuels and industrial gases are not emissions from their own facilities, but potential emissions from the eventual use of their products, the individual companies' reports are less important than the overall figures.  As such, EPA proposes a balancing approach – making sector-by-sector determinations and releasing data about emissions only when it would not cause substantial harm to the businesses’ competitive position. (Specifics on how data will be treated are available here.)   Comments are due 60 days after the proposed rules are published in the federal register.
