We recommend correcting some inadvertent errors that were made in the process of preparing the 

signature package for the proposed rule, Standards of Performance for Greenhouse Gas Emissions 

from New Stationary Sources: Electric Utility Generating Units, which was signed on 

September 20, 2013 . The attached red-line/strike-out version of the preamble and rule identifies 

these errors and shows the corrected text, and does the same for some typographical and 

grammatical errors. In addition, this version includes several non-substantive edits primarily to 

make the package consistent with the requirements of the Federal Register. 1 

Preamble: 

Page 2, SUMMARY, is amended by adding as the last sentence "This action also includes 

related proposals concerning permitting fees under Clean Air Act Title V, the Greenhouse 

Gas Reporting Program, and the definition of the pollutant covered under the prevention of 

significant deterioration program." This change provides the public with adequate notice of 

non-standard-of-performance proposed rules. 

1 These page number cited refers to the red line/strikeout version of the preamble and rule; the corrections could occur 

earlier or later in the corrected version.

Page 83, first full sentence, is amended by replacing "supplies" with "is constructed for the 

purpose of supplying" to' state correctly that "Second, we are proposing to revise the third 

criteria to be met if the EGU is constructed for the purpose of supplying "more than 

219,000 MWh," as opposed to "25 MW," net-electrical output to the grid." 

Page 153, B. Applicability Requirements- Today's Proposal, first sentence, is amended by 

deleting "applicability should be based on electric sales alone, so that the proposed" to state 

correctly that "In today's rulemaking, we propose that standards of performance apply to a 

facility if the facility supplies more than one-third of its potential electric output and more 

than 219,000 MWh net electric output to the grid per year." 

Page 218, footnote 188 text reference, is amended by adding footnote 188 to correctly state 

that "An Assessment ofthe Commercial Availability of Carbon Dioxide Capture and 

Storage Technologies as of June 2009," PNNL-18520, Pacific Northwest National 

Laboratory, Richland, WA, June 2009. Available at: 

http://www.pnl.gov/main/publications/external/technical_reports/PNNL-18520.pdf." 

Page 269, third paragraph, third sentence, is amended by adding "than" to state correctly 

that "This is because control of criteria pollutants and HAPs often involves the use of a 

pollution control device that results in significant reductions, often greater than 90 

percent." 

Page 276, first paragraph, third sentence, is amended to read "Specifically, Subpart PP 

requires facilities with production process unit(s) that capture a C02 stream for purposes of 

supplying C02 for commercial applications or that capture and maintain custody of a C02 

stream in order to sequester or otherwise inject it underground and which meet certain 

applicability requirements to report the mass of C02 captured." This change correctly 

summarizes subpart PP of the GHG Reporting Program. 

Page 295, third full sentence, is amended by adding "on" to state correctly that "These 

subcategories are based on whether the design heat input rate to the turbine engine is either 

less than or equal to 850 MMBtulh or greater than 850 MMBtu/h." 

Page 301, second paragraph, is amended by adding "of' to state correctly that "In the 

alternative, if the Tailoring Rule thresholds would not continue to apply when the EPA 

promulgates requirements under CAA section 111, then the EPA would assess whether to 

proceed with a separate rulemaking action to narrow its approval of all ofthe State's 

approved SIP PSD programs to assure that for federal purposes, the Tailoring Rule 

thresholds will continue to apply as of the effective date of the final rule that EPA is 

proposing today." 

In addition, in various places in which the withdrawal of the original proposal (from April, 2012) is 

discussed, we changed "rescind" to "withdraw" to be consistent with the terminology in the 

withdrawal notice (e.g., pages 9, 15, 19, 38).
