ENVIRONMENTAL PROTECTION 

AGENCY 

40 CFR Part 60 

[AD-FRL-2489-2] 

New Source Performance Standard; 

Steam Generating Units 

AGENCY: Environmental Protection ' 

Agency (EPA). 

ACTION: Advance notice of proposed 

rulemaking. 

SUMMARY: In today's Federal Register, 

performance standards are being 

proposed for the control of particulate 

matter and nitrogen oxides (NO,) 

emissions from industrial-commercialinstitutional steam generating units of 

greater than 29 MW (100 million Btu/ 

hour) heat input capacity. The purpose 

of this advance notice is to advise the 

public that regulatory activities are 

being initiated for three other categories 

of steam generating units. The first 

category'of regulatory activity is the 

development of performance standards 

to limit the emission of sulfur dioxide 

(SO2) from industrial-commercialinstitutional steam generating units. The 

second category of regulatory activity is 

the development of performance 

standards for steam generators of less 

than 29 MW (100 million Btu/hour) heat 

input capacity. The third category of 

regulatory activity is a review of 

performance standards for electric 

utility steam generating units (§ 60.40a; 

Subpart Da) which were adopted in 

1979. Technical data and comments on 

these activities are requested. 

DATES: Comments must be received on 

or before September 17,1984. 

ADDRESS: Comments should be 

submitted to the Central Docket Section 

(LE-131), U.S. Environmental Protection 

Agency, 401M Street, SW„ Washington, 

D.C, 20460. Comments and data related 

to development of (SO-0 performance 

standards for industrial-commercialinstitutional steam generating units 

larger than 29 MW (100 million Btu/ 

hour) heat input capacity should be 

addressed to Docket Number A-83-27. 

Comments and data related to 

development of performance standards 

for steam generating units of less than 

29 MW (100 million Btu/hour) heat input 

capacity should be addressed to Docket 

Number A-83-46. 

Comments and data related to review 

of performance standards for electric 

utility steam generating units (§ 60.40a; 

Subpart Da) should be addressed to 

Docket Number A-83-45.

SUPPLEMENTARY INFORMATION: 

Background 

In addition to today's proposal of 

performance standards for the control of 

particulate matter and nitrogen oxides 

(NO J emissions from industrialcommercial-institutional steam 

generating units of greater than 29 MW 

(100 million Btu/hour) heat input 

capacity, this advance notice is to 

advise the public of regulatory activities 

in three other categories of steam 

generating units. 

The first category of regulatory 

activity is the development of 

performance standards to limit the 

emissions of sulfur dioxide (SO2) from 

industrial-commercial-institutional 

steam generating units of greater than 29 

MW (100 million Btu/hour) heat input 

capacity. In developing the standards, a 

wide range of NO2 control alternatives 

are being investigated for basis of the 

SO2 standards including, but not limited 

to, low sulfur fuel, fuel pretreatment, 

"dry" flue gas desulfurization, "wet" 

flue gas desulfurization, and fluidized ' 

bed combustion technology. The final 

selection of the technological basis of 

the standard will be made in accordance 

with the requirements of section 111 of 

the Clean Air Act as amended. Drafts of 

background documents describing SO2 

emission control techniques and their 

performance and costs are scheduled to 

be available for public review and 

comment in the fall of 1984. 

The second category of regulatory 

activity includes the development of 

performance standards for steam 

generating units of less than 29 MW (100 

million Btu/hour) heat input capacity. 

Steam generating units in this size range 

would be expected to be principally 

commercial-institutional in character 

and to principally fire natural gas or fuel 

oil. A limited amount of solid fuel would 

be expected to be fired in this source 

category. The development of 

performance standards for this category 

will consider the control of particulate 

matter, SO2 and NO, emissions. As 

development work is completed for this 

category of steam generating units, 

documents describing the category, 

emission control techniques, 

performance level, and cost are 

expected to become available for review 

and comment in the spring of 1986. 

The third category of regulatory 

activity is the 4-year review of the 

performance standard for electric utility 

steam generating units (40 CFR 60.4Qa; 

Subpart Da). This standard was adopted 

in 1979 and, as required by section 111 

of the Clean Air Act, a 4-year review is 

being initiated. Because of the typical 5 

to 7 year time period necessary to 

design and construct a new electric 

utility steam generating unit, new utility 

units subject to Subpart Da are just now 

initiating operation. Thus, the review 

will be constrained to some extent by 

limitation in operating data available 

from units subject to Subpart Da. 

However, the review will address both 

the particulate matter, SO2, and NO, 

standards and the applicable emission 

control technologies. Areas of particular 

interest would include a review of the 

progress that has been made in "dry" 

flue gas desulfurization system since 

1979, particularly spray-dryer systems, 

the use of adipic acid to improve flue 

gas desulfurization system operability, 

and the status of development of "lowNO," burners (staged combustion 

burners) for pulverized coal 

applications. The review of Subpart Da 

will also include an investigation of 

technical adjustments to the standards 

such as performance test methods and 

recordkeeping and reporting 

requirements. As progress is made in the 

review of this standard, documents will 

be made available for public review and 

comment. 

Request for Information 

A substantial amount of information 

on control of particulate matter, SO2, 

and NO, emissions from steam 

generating units was gathered in 1977-

1980; however, this information may 

need to be updated to reflect recent 

developments. Relative to the 

development or review of standards of 

performance for the three categories of 

steam generating units, data and 

comments are requested. Specifically, 

performance and cost data are 

requested for the application of flue gas 

desulfurization technology to industrialcommercial-institutional steam 

generating units of greater than 29 MW 

(100 million Btu/hour) heat input 

capacity. Information on all types of flue 

gas desulfurization systems, including 

dry injection, spray-dryer, wet scrubbing 

systems, and fluidized bed combustor 

systems, are solicited. 

For steam generating units of less than 

29 MW (100 million Btu/hour) heat input 

capacity, technical and cost data are 

requested on the control of particulate 

matter, SO2 and NOx. Specifically, 

performance and cost information on the 

use of combustion air oxygen trim 

systems and on the application of staged 

combustion burners (SCB) for NO„ 
P.4 

Federal Register / Vol. 49, No. 119 / Tuesday, June 19, 1984 / Proposed Rules 25153 

control is requested. Within the last 3 

years, significant advancements appear 

to have been made with these 

technologies. 

For electric utility steam generating 

units (Subpart Da), performance and . 

cost data are specifically requested on 

dry injection, spray-dryer, and wet 

scrubbing flue gas desulfurization 

systems for SO2 control and on the 

application of SCB technology for NOx 

control of pulverized coal-fired steam 

generating units. Comments on technical 

amendments to general requirements 

under Subpart Da, (such as monitoring, 

recordkeeping, and reporting) are also 

requested. 

In summary, regulatory development 

(or review) of standards of performance 

for three categories of steam generating 

units is being announced. Interested 

individuals are invited to submit 

information or comments relating to the 

current status, performance, and costs 

associated with various emission 

control techniques for controlling 

emissions from these categories of 

steam generating units. 

Miscellaneous 

A regulatory flexibility analysis under 

5 U.S.C. 601, et seq., is not required for 

this notice. This notice would not 

impose any new regulatory 

requirements, nor would it impose any 

additional costs. This notice is also 

considered nonmajor under Executive 

Order 12291.
