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 to 

EPA’s docket at https://

www.regulations.gov 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 

https://www.epa.gov/dockets/ 

commenting-epa-dockets for additional 

submission methods; the full EPA 

public comment policy; information 

about CBI, PBI, or multimedia 

submissions; and general guidance on 

making effective 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 

www.regulations.gov 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). 

• 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.

Comment 

The EPA is requesting comment on 

one new chapter of the EPA Air

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 https://www.epa.gov/ 

economic-and-cost-analysis-airpollution-regulations/cost-reports-andguidance-air-pollution#cost%20manual, 

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-todate 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 SO2 and acid gas? Please 

provide information, if possible, on 

descriptions of and background on 

control by DSI 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 DSI to 

various types of emissions sources 

complete, up to date, and accurate? 

(4) Are the estimates of SO2 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 SO2 and acid gas control 

efficiency and overall efficiency? What 

are the costs of including such 

techniques in the design and operation 

of DSI?
