SUPPLEMENTARY INFORMATION: The EPA is requesting comment on the
specific Control Cost Manual chapter included in this notice.
Written Comments: Submit your comments, identified by Docket ID No.
EPA-HQ-OAR-2015-0341, at <a href="https://www.regulations.gov">https://www.regulations.gov</a> (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 to EPA's docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> any information
you consider to be Confidential Business Information (CBI), Proprietary
Business Information (PBI), or other information whose disclosure is
restricted by statute. 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). Please visit <a href="https://www.epa.gov/dockets/commenting-epa-dockets">https://www.epa.gov/dockets/commenting-epa-dockets</a> for additional submission methods; the

comments.
I. General Information
A. What should I consider as I prepare my comments for the EPA?
1. Submitting CBI. Do not submit this information to the EPA
through <a href="http://www.regulations.gov">www.regulations.gov</a> or email. 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.
2. 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).
<bullet> Follow directions--The agency may ask you to respond to
specific questions or organize comments by referencing a CFR part or
section number.
<bullet> Explain why you agree or disagree; suggest alternatives
and substitute language/data for your requested changes.
<bullet> Describe any assumptions and provide any technical
information and/or data that you used.
<bullet> If you estimate potential costs or burdens, explain how
you arrived at your estimate in sufficient detail to allow for it to be
reproduced.
<bullet> Provide specific examples to illustrate your concerns and
suggest alternatives.
<bullet> Explain your views as clearly as possible, avoiding the
use of profanity or personal threats.
<bullet> 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 new chapter of the EPA Air
[[Page 102138]]
Pollution Control Cost Manual. The Control Cost Manual contains
individual chapters on emissions 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, and data
concerning the percentage of pollutant emissions that control measures
can reduce. 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
(BACT) under the New Source Review Program, the Regional Haze Program,
Reasonably Achievable Control Technology (RACT) for State
Implementation Plans (SIPs) and for other programs.
The one updated Control Cost Manual chapter is: Chapter 2, Section
5, ``Dry Sorbent Injection.'' 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) is available at <a href="https://www.epa.gov/economic-and-cost-analysis-air-pollution-regulations/cost-reports-and-guidance-air-pollution#cost%20manual">https://www.epa.gov/economic-and-cost-analysis-air-pollution-regulations/cost-reports-and-guidance-air-pollution#cost%20manual</a>, 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. Since 2014, 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, the Carbon Adsorbers
(Chapter 1, Section 3, Section 3.1) and Flares (Chapter 1, Section 3,
Section 3.2) chapters in October 2018, and the Gas Absorbers (now Wet
and Dry Scrubbers for Acid Gas, Chapter 1, Section 5) chapter in May
2021. Finally, the EPA is currently updating the Fabric Filters
(Chapter 1, Section 6) chapter, with the expected date for its
finalization to be in 2025.
To help focus review of the Dry Sorbent Injection chapter, we offer
the following list of questions that the EPA is particularly interested
in addressing in this new Control Cost Manual chapter. Regardless of
the topics that are covered in this list of questions, 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 Dry Sorbent Injection Chapter
(1) What is a reasonable and up-to-date estimate of equipment life
(defined as design or operational life) for dry sorbent injection (or
DSI) systems--that is, an entire DSI system? Please provide data, if
possible, on accurate estimates of equipment life.
(2) Are the descriptions of and technical background on DSI
complete, up to date, and accurate with regard to control of
SO<INF>2</INF> and acid gas? Please provide information, if possible,
on descriptions of and background on control by DSI of SO<INF>2</INF>
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 DSI to various types of emissions
sources complete, up to date, and accurate?
(4) Are the estimates of SO<INF>2</INF> removal or control
efficiency for DSI accurate and up-to-date? If not, what are more
accurate estimates? Please provide data, if possible, to address
inaccuracies. Please offer the same for acid gas (e.g., hydrogen
chloride (HCl)) removal or control efficiency.
(5) Is the information accurate on how DSI operate in tandem with
control technologies such as fabric filters and electrostatic
precipitators (ESP) to reduce particulate matter (PM) and activated
carbon injection (ACI) to reduce mercury? Please provide data, if
possible, to address inaccuracies.
(6) Are the capital cost correlations, factors, and equations for
DSI applied to various types of emissions sources and industries
accurate and up to date? If not, how should they be revised? Please
provide data, if possible, to address inaccuracies.
(7) Are the annual costs (such as operating and maintenance costs)
for DSI applied to various types of emissions sources and industries
accurate and up-to-date? In particular, are the sorbent data, both
types of sorbent and sorbent prices, for use in DSI accurate and up-to-
date? If not, how should they be revised? Please provide data, if
possible, to address inaccuracies.
(8) How can neural networks and computational fluid dynamics be
used, separately or integrated, to enhance the design and optimization
of DSI for improved SO<INF>2</INF> and acid gas control efficiency and
overall efficiency? What are the costs of including such techniques in
the design and operation of DSI?
