I. General Information

A. Written Comments

    Submit your comments, identified by Docket ID No. EPA-HQ-OAR-2015-
0341, at https://www.regulations.gov (our preferred method), or the 
other methods identified in the ADDRESSES section. Once submitted, 
comments cannot be edited or removed from the docket. The EPA may 
publish any comment received to its public docket. Do not submit 
electronically any information you consider to be Confidential Business 
Information (CBI) or other information whose disclosure is restricted 
by statute. Clearly mark the part or all of the information that you 
claim to be CBI. For CBI information in a disk or CD-ROM that you mail 
to the EPA docket office, mark the outside of the disk or CD-ROM as CBI 
and then identify electronically within the disk or CD-ROM the specific 
information that is claimed as CBI. In addition to one complete version 
of the comment that includes information claimed as CBI, a copy of the 
comment that does not contain the information claimed as CBI must be 
submitted for inclusion in the public docket. Information so marked 
will not be disclosed except in accordance with procedures set forth in 
40 Code of Federal Regulation (CFR) part 2. Multimedia submissions 
(audio, video, etc.) must be accompanied by a written comment. The 
written comment is considered the official comment and should include 
discussion of all points you wish to make. The EPA will generally not 
consider comments or comment contents located outside of the primary 
submission (i.e., on the web, cloud, or other file sharing system). For 
additional submission methods, the full EPA public comment policy, 
information about CBI or multimedia submissions, and general guidance 
on making effective comments, please visit https://www.epa.gov/dockets/commenting-epa-dockets.
    The EPA is temporarily suspending its Docket Center and Reading 
Room for public visitors, with limited exceptions, to reduce the risk 
of transmitting COVID-19. Our Docket Center staff will continue to 
provide remote customer service via email, phone, and webform. We 
encourage the public to submit comments via https://www.regulations.gov/ as there may be a delay in processing mail and 
faxes. Hand deliveries or couriers will be received by scheduled 
appointment only. For further information and updates on EPA Docket 
Center services, please visit us online at https://www.epa.gov/dockets.
    The EPA continues to carefully and continuously monitor information 
from the Centers for Disease Control and Prevention (CDC), local area 
health departments, and our Federal partners so that we can respond 
rapidly as conditions change regarding COVID-19.

B. Tips for Preparing Your Comments

    When submitting comments, remember to: Identify the notification by 
docket number and other identifying information (subject heading, 
Federal Register date and page number).
     Follow directions--The agency may ask you to respond to 
specific questions or organize comments by referencing a CFR part or 
section number.
     Explain why you agree or disagree; suggest alternatives 
and substitute language/data for your requested changes.
     Describe any assumptions and provide any technical 
information and/or data that you used.
     If you estimate potential costs or burdens, explain how 
you arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
     Provide specific examples to illustrate your concerns and 
suggest alternatives.

     Explain your views as clearly as possible, avoiding the 
use of profanity or personal threats.
     Make sure to submit your comments by the comment period 
deadline identified.

II. Information Available for Public Comment

    The EPA is requesting comment on one updated chapter of the EPA Air 
Pollution Control Cost Manual. The Control Cost Manual contains 
individual chapters on control measures, including data and equations 
to aid users in estimating capital costs for installation and annual 
costs for operation and maintenance of these measures. The Control Cost 
Manual is used by the EPA for estimating the impacts of rulemakings, 
and serves as a basis for sources to estimate costs of controls that 
are Best Available Control Technology under the New Source Review 
Program, and Best Available Retrofit Technology under the Regional Haze 
Program and for other programs.
    The one updated Control Cost Manual chapter is: Chapter 1, Section 
5, ``Wet Scrubbers for Acid Gas'' (to be renamed ``Wet and Dry 
Scrubbers for Acid Gas''). This chapter in the Control Cost Manual 
will, for the first time, include cost and performance data for dry 
scrubbers as well as wet scrubbers. This revised Control Cost Manual 
chapter can be found in the docket for the Control Cost Manual update 
(Docket ID No. EPA-HQ-OAR-2015-0341). The current Control Cost Manual 
version (sixth edition) including the current chapter is available at 
http://epa.gov/ttn/catc/products.html#cccinfo, and last updated in 
2003. The Consolidated Appropriations Act of 2014 requested that the 
EPA begin development of a seventh edition of the Control Cost Manual. 
The EPA has met with state, local, and tribal officials to discuss 
plans for the Control Cost Manual update as called for under the 
Consolidated Appropriations Act of 2014. The EPA has met with other 
groups as well at their request. The EPA has updated the selective non-
catalytic reduction (SNCR) and selective catalytic reduction (SCR) 
chapters, the first two chapters (Chapter 1, Section 4; Chapter 2, 
Section 4, respectively) completed for the seventh edition of the 
Control Cost Manual, and made them available to the public in May 2016 
(81 FR 38702, June 14, 2016) and also updated these chapters again in 
May 2019. In addition, the EPA has updated the Refrigerated Condensers 
(Chapter 1, Section 3 and Section 3.1) and Incinerators (Chapter 2, 
Section 3, Section 3.2, now Incinerators/Oxidizers) chapters in 
November 2017, the Cost Estimation: Concepts and Methodology chapter 
(Chapter 2, Section 1) as of November 2017, and also the Carbon 
Adsorbers (Chapter 1, Section 3, Section 3.1) and Flares (Chapter 1, 
Section 3, Section 3.2) chapters in October 2018.
    To help focus review of the Wet Scrubbers for Acid Gas (or Wet and 
Dry Scrubbers) chapter, we offer the following list of questions that 
the EPA is particularly interested in addressing in the updated 
chapter. Commenters are welcome to address any aspects of this chapter. 
Please provide supporting data for responses to these questions and for 
other comments on the chapter.

For the Wet and Dry Scrubbers for Acid Gas Chapter

    (1) What is a reasonable and up-to-date estimate of equipment life 
(defined as design or operational life) for wet scrubbers (FGD)? Dry 
scrubbers? Please provide data, if possible, on accurate estimates of 
equipment life.
    (2) Are the descriptions of wet FGD scrubbers complete, up-to-date, 
and accurate with regard to control of SO2 and acid gases? 
Dry scrubbers? Please provide information, if possible, on descriptions 
of wet and dry scrubbers' control of SO2 and acid gases if 
you do not believe that the descriptions in the draft chapter are 
complete, up-to-date, and accurate.
    (3) Is the applicability of wet FGD scrubbers to various types of 
emissions sources complete, up-to-date, and accurate? Dry scrubbers?
    (4) Are the cost correlations, factors, and equations for wet FGD 
scrubbers accurate and up-to-date? For dry scrubbers? If not, how 
should they be revised? Please provide data, if possible, to address 
inaccuracies.
    (5) Are the estimates of SO2 removal or control 
efficiency for wet FGD scrubbers accurate and up-to-date? For dry 
scrubbers? If not, what are more accurate estimates? Please provide 
data, if possible, to address inaccuracies.
