Supporting Statement for the

Control Technology Determinations for Constructed and 

Reconstructed Major Sources of Hazardous Air Pollutants,

40 CFR part 63, subpart B

	Prepared by

	Office of Air Quality Planning and Standards

	Part A of the Supporting Statement

1.	IDENTIFICATION OF THE INFORMATION COLLECTION

1(a)	Title of the Information Collection

This Information Collection Request (ICR) is entitled “Control
Technology Determinations for Constructed and Reconstructed Major
Sources of Hazardous Air Pollutants (40 CFR part 63, subpart B)” and
numbered as EPA ICR Number 1658.05 and Office of Management and Budget
(OMB) Control Number 2060-0373.  

1(b)	Short Characterization

Section 112(g)(2)(B) of the Clean Air Act as amended in 1990 (CAA)
requires that maximum achievable control technology (MACT) standards be
met by constructed or reconstructed major sources of hazardous air
pollutants (HAP).  Where no applicable emission limit has been set, the
MACT determination shall be made on a case-by-case basis.

This ICR supports the regulations at 40 CFR part 63, subpart B (sections
63.40 – 63.44) to implement section 112(g).  It addresses the
information collection burden (hours and costs) to three parties:  (1)
industry respondents subject to these provisions, (2) State, local, and
Tribal agencies that review applications made under these provisions,
and (3) EPA for oversight review of a percentage of State/local
decisions.  The information collection activities for which burden
estimates are calculated are summarized below.

Owners or operators who construct or reconstruct a major source of HAP
emissions must comply with any applicable MACT standard.  Where no MACT
standard exists, a case-by-case determination of MACT (case-by-case
MACT) under CAA section 112(g) must be made.  The owner or operator is
responsible for obtaining such a case-by-case MACT determination.  This
ICR contains supporting information for case-by-case MACT
determinations.

State, local, and Tribal agencies with operating permit programs that
have been approved by EPA will review applications submitted by sources
under the CAA section 112(g) provisions.  These permitting agencies must
determine the level of control that will be necessary to meet
case-by-case MACT requirements for new sources.  Finally, EPA will
review a percentage of the determinations in order to provide oversight
of the various State, local, and Tribal permitting authorities.

2.	NEED FOR AND USE OF THE COLLECTION

2(a)	Need / Authority for the Collection

This information is needed and used to determine if the entity
submitting an application for a case-by-case MACT determination has met
the criteria established in the CAA section 112(g) rule.  This
information is necessary for the State or local agency to make the
case-by-case determination.  Finally, this information is needed by the
Administrator to review a portion of the case-by-case determinations to
ensure that the program is functioning as intended.

The need and authority for this information collection is contained in
CAA section 112(g) 42 U.S.C. 7401 (et seq.) as amended by Pub. L.
101-549.

2(b)	Practical Utility / Users of the Data

The information collected in the CAA section 112(g) applications
provides (for the purposes of compliance determination) documentation of
the selection of a particular control technology for case-by-case MACT. 
Applications are reviewed by a State or local agency for which authority
has been delegated by EPA to make the requisite determinations.  In
addition, EPA will review some applications as an oversight function.

3.	NONDUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA

3(a)	Nonduplication

This information collection is not unnecessarily duplicative of
information otherwise reasonably accessible to us.  For instances where
other information items (e.g., a site plan) may have been previously
collected from source owners or operators by the permitting authority in
support of other applications, it is possible to use this information to
meet all or part of the requirements of this information collection.  In
general, however, most items of information are tailored specifically
for the individual case-by-case MACT determinations, meaning that
previously submitted information is likely to be inadequate for CAA
section 112(g) purposes.

3(b)	Public Notice Required Prior to ICR Submission to OMB

We solicited public comments on this ICR prior to submitting it to OMB. 
We issued a Federal Register notice requesting comments on the ICR
renewal on May 22, 2008 (73 FR 29750).  We received no comments.

3(c)	Consultations

The final rule for subpart B was issued on December 27, 1996 (61 FR
68384).  Since then, we have gained extensive experience in working with
the State and local agencies in developing case-by-case MACT
determinations for sources subject to CAA section 112(g).  We have
consulted with knowledgeable State agency staff who have been involved
in making case-by-case MACT determinations over the past 3 years and
potential industry respondents.  We used this information to prepare
this ICR renewal package.

In general, the State contacts confirmed that there has been a low level
of activity related to CAA section 112(g) applications over the last few
years and that most of the applications were for major sources that were
eventually subject to CAA section 112(d) MACT standards or for sources
that ended up taking enforceable permit limits to keep their emissions
below the CAA section 112(g) applicability threshold (i.e., major source
status).  They confirmed that the relative burden hours for the State
review of these applications was on average reasonable.  They also
reported that there were no major concerns related to the burden
associated with the section CAA 112(g) requirements by the permit
applicants they worked with.  The industry contact raised no major
issues with the hourly burden estimate at this point.

The following table lists the contact information of the people we
consulted.

Name	Agency	Phone Number

James Geier	Colorado Department of Public Health and Environment
303/692/3167

Joseph Eller	South Carolina Department of Health and Environmental
Control	803/898-4079

Cindy Phillips	Florida Department of Environmental Protection
850/921-9534

Brian Toth	Southern Company	205/257-7440

3(d)	Effects of Less Frequent Collection

This section does not apply because the information required to be
submitted by each applicant would be submitted on a one-time-only basis.

3(e)	General Guidelines

None of the general information collection guidelines in 5 CFR
1230.5(d)(2) of the OMB regulations implementing the Paperwork Reduction
Act is being exceeded in the CAA section 112(g) regulations.

3(f)	Confidentiality

All information submitted to us for which a claim of confidentiality is
made will be safeguarded according to the policies set forth in Title
40, Chapter 1, part 2, subpart B, Confidentiality of Business
Information.  See 40 CFR; 41 FR 36902, September 1, 1976; amended by 43
FR 3999, September 8, 1978; 43 FR 42251, September 28, 1978; and 44 FR
17674, March 23, 1979.  Even where we have determined that data received
in response to an ICR is eligible for confidential treatment under 40
CFR part 2, subpart B, we may nonetheless disclose the information if it
is “relevant in any proceeding” under the statute [42 U.S.C.
7414(c); 40 CFR 2.301(g)].  The information collection complies with the
Privacy Act of 1974 and OMB Circular 108.

3(g)	Sensitive Questions

This section is not applicable.  This ICR does not contain any sensitive
questions relating to sexuality, religious beliefs, or other matters
usually considered private.

4.	THE RESPONDENTS AND THE INFORMATION REQUESTED

4(a)	Respondents / SIC Codes

Respondents include owners/operators of constructed or reconstructed
major sources of HAP where no applicable MACT emission limit has been
set.  The section 112(g) regulations define “construct a major
source” and “reconstruct a major source” at 40 CFR 63.41 (also see
Section 6(a)(i) of this document).  A major source is defined as one
that emits more than 10 tons per year of any HAP, 25 tons per year for a
combination of all HAP, or amounts exceeding any lesser quantity cutoff
established under 40 CFR part 63.  This definition of major source cuts
across a wide variety of industries, including both manufacturing and
non-manufacturing sources.  See Attachment 1 for a list of potentially
affected industry sectors; this list is not exhaustive but provides a
good idea of the types of source categories that could be affected. 
Potentially affected sources also include those formerly subject to the
now-vacated MACT standards for polyvinyl chloride and copolymers
production; brick and structural clay products manufacturing; clay
ceramics manufacturing; and industrial, commercial, and institutional
boilers and process heaters.  Also potentially affected are electric
utility steam generating units (EGUs).  EGUs were added to the section
112(c) source category list in December 15, 2000 and became subject to
section 112(g) at that time.  (See 40 CFR 63.40(c).)   EPA removed EGUs
from the source category list in a rule published on March 29, 2005. 
However, on Feb. 8, 2008, the United States Court of Appeals for the
District of Columbia Circuit vacated that rule. (State of New Jersey v.
EPA, No. 05-1097) and thus EGUs are a listed source category and section
112(g) applies.   Once EPA promulgates national MACT standards for a
source category, CAA section 112(g) no longer applies to sources in that
source category.

Respondents also include State, local and tribal agencies that make the
case-by-case MACT determinations.  These government establishments are
classified as Air and Water Resource and Solid Waste Management Programs
under Standard Industrial Classification (SIC) code 9511 and North
American Industry Classification System (NAICS) code 92411.

4(b)	Information Requested

(i)	Data Items, Including Recordkeeping Requirements

All items addressed in this ICR involve information submitted with the
application.  There are no recordkeeping requirements per se, although
some of the information necessary to document control options would
require the source to have kept records of certain information.  The
data items for the CAA section 112(g) rule consist of the following:

Actual Emissions.  Sources complying with the requirements of CAA
section 112(g) under the case-by-case MACT provisions (i.e., constructed
and reconstructed major sources) generally do not have to provide
detailed analytic determinations of individual HAP if the owner/operator
agrees that the HAP emissions will exceed major source thresholds that
will subject the construction or reconstruction to the CAA section
112(g) requirements.  Rather, the source needs only to identify and
quantify classes and types of pollutants to a sufficient degree to
support the MACT evaluation.

Case-by-Case MACT Determination.  The source owner or operator must
submit the following information when it performs a case-by-case MACT
determination [40 CFR 63.43(e)]:

The name and address (physical location) of the major source and
affected source(s) undergoing construction or reconstruction;

A brief description of the major source, its source category or
subcategory, and a description of the affected stationary source(s)
requiring a MACT determination;

The expected commencement date of the construction or reconstruction of
the affected source;

The expected completion date of the construction or reconstruction of
the affected sources;

The anticipated date of start-up;

The type of HAP emitted by each emission unit and the emission rate for
each HAP;

Any federally-enforceable emission limitations applicable to the
MACT-affected emissions units;

The maximum capacity and expected utilization, and associated
uncontrolled emission rates, for the MACT-affected emissions units
(potential to emit in an uncontrolled state);

Controlled emissions for the MACT-affected emission unit in tons per
year (potential to emit in a controlled state); and

A recommended emission limitation for the MACT-affected emission unit
that complies with all relevant emission standards.

If the application specifies additional control technology or a change
in control technologies, the application must include:

The candidate control technology to meet the emission limitation
including technical information on the design, operation, size,
estimated control efficiency, etc.;

Supporting documentation including identification of alternative control
technologies considered to meet the emission limitation, and an analysis
of non-air quality health environmental impacts or energy requirements
for the selected MACT candidate; and 

Any other information which may be required pursuant to 40 CFR part 63,
subpart A.

	(ii) Respondent Activities.

Activities that the owner or operator must perform are listed in this
section.

Read applicable regulations to determine compliance requirements

Assemble necessary source information, including source identification
and descriptive information, construction schedules, sufficient data on
classes and types of pollutants to support the MACT evaluations, and
potential to emit (controlled and uncontrolled)

Identify and describe MACT candidate, any required MACT limits, expected
emissions limitation, and MACT installation schedule

Prepare and submit application

Revise application per comments received from the permitting authority,
ensuring compliance with case-by-case MACT decision

The permitting authority, typically the State, local or Tribal air
agency, will perform the following activities:

Answer respondent questions;

Log in and review applications;

Request additional information for incomplete applications;

When no MACT standard has been promulgated, verify that the source will
achieve the level of control necessary to meet case-by-case MACT
requirements for constructed or reconstructed sources; and

Inform source of permitting authority's decision regarding the
application.

5.	THE INFORMATION COLLECTED -- AGENCY ACTIVITIES, COLLECTION
METHODOLOGY, AND INFORMATION MANAGEMENT

5(a)	Agency Activities

In carrying out its oversight role, EPA will review the decision of the
permitting authority.

5(b)	Collection Methodology and Management

It will be the responsibility of the owners or operators of the
constructed or reconstructed major sources affected by these regulations
to submit an application to the permitting authority.  Applications will
be prepared and submitted according to guidance issued in conjunction
with the CAA section 112(g) rules.  No forms are contained in the
regulations for CAA section 112(g) applications.

The permitting authority will determine how to log in and track
applications.  MACT determinations are performed on a case-by-case
basis.  It will also be the responsibility of the permitting authority
to provide EPA with the information necessary for oversight review.

For each application, the applicant will be required to supply
information on how the data were obtained (e.g., indicate whether the
emissions data were obtained through the use of emission factors or test
data) and how calculations were performed.  Qualified staff at the
permitting authority will check the quality of data submitted by the
applicant on a case-by-case basis.  This will be done by reviewing
control technology determinations for similar sources, by reviewing test
data, and by checking engineering calculations.  Confidential
information submitted by the applicant will be handled by the permitting
authority in conformance with confidential information handling
procedures.  No specific provisions have been made for electronic
methods of submittal.

The CAA section 112(g) regulations will not require the request of
information through any type of survey.

5(c)	Small Entity Flexibility

Minimizing the information collection burden for all sizes of
organizations is a continuing principle for our efforts.  The CAA
section 112(g) regulations only include the application, recordkeeping
and reporting requirements we need to determine compliance with the
rule.  We have reduced the collection burden to the extent practicable
and appropriate, including consideration of the resources available to
the respondents and clarifying, consolidating, and simplifying the
requirements.  Furthermore, we do not anticipate that any small entities
will be participating in this program.

5(d)	Collection Schedule

Each source affected by the CAA section 112(g) regulations will be
required to submit an application.  Preparation of the application in
compliance with the CAA section 112(g) rules is a one-time-only activity
(i.e., once for each construction or reconstruction subject to the CAA
section 112(g) provisions).  The CAA section 112(g) regulations will not
require periodic reporting or surveys.

6.	ESTIMATING THE BURDEN AND COST OF THE COLLECTION

6(a)	Estimating Respondent Burden

(i)	Estimating Industry Burden

Respondents include owners/operators of major sources of HAP, for which
no MACT standard is in effect, that undertake construction or
reconstruction.  To construct a major source means generally to
fabricate, erect, or install at any “greenfield” site a major source
of HAP, or to fabricate, erect, or install at any developed site a new
process or production unit which in and of itself is a major source (40
CFR 63.41).  To reconstruct a major source means to replace components
of an existing process or production unit that in and of itself is a
major source of HAP to the extent that the fixed capital costs of the
replacement components exceeds 50 percent of the fixed capital cost that
would be required to  construct a comparable process or production unit,
and it is technically and economically feasible for the reconstructed
major source to meet the applicable MACT emission limitation of new
sources established under the CAA section 112(g) regulations.  (id.)  In
calculating the burden hours for this ICR, we made assumptions about the
number of sources that would submit applications each year.  As
discussed in more detail in Section 6(d), Estimating the Respondent
Universe and Total Burden Costs, we have conservatively estimated that
there could be about 73 sources affected by CAA section 112(g) over the
next 3 years.

We retained the same activities and burden hour estimates per respondent
used in the previous ICR (ICR Number 1658.04).  Based on our
consultations, we did not identify any concerns that the burden hours
associated with preparing an application are understated.  Contacts
noted that these sources are often also complying with New Source Review
requirements and other State preconstruction permitting as well.  The
additional information needed that is unique to the CAA section 112(g)
application is an estimate of HAP emissions.

The total hours associated with preparing the application in Table 1 are
for technical hours only.  Consistent with previous ICRs, we calculated
management hours as 5 percent of technical hours and clerical hours as
10 percent of technical hours.  Table 4 contains the results of the
burden hours calculation for each activity during each year of this ICR.
 Overall, the CAA section 112(g) regulations contain an average burden
of 4,198 hours per year.

(ii)	Estimating State, Local, and Tribal Agency Burden

The estimated number of State, local and Tribal agency respondents is
equal to the number of estimated permit applications.  We retained the
same activities and burden hour estimates per respondent used in the
previous ICR (ICR Number 1658.04).  Based on our consultations, we
determined that the previous estimate of 80 technical hours per
application is a reasonable average estimate.  Some applications might
be more complex and take more hours, but others would be similar to
other sources and/or MACT standards or represent simple scenarios and
would take fewer hours.

The total hours associated with preparing the application in Table 2 are
for technical hours only.  Consistent with previous ICRs, we calculated
management hours as 5 percent of technical hours and clerical hours as
10 percent of technical hours.  Table 4 contains the results of the
burden hours calculation for each activity during each year of this ICR.
 Overall, the CAA section 112(g) regulations contain an average burden
of 2,239 hours per year for State, local, and Tribal agencies.

6(b)	Estimating Respondent Costs

(i)	Estimating Industry Costs

Wage rates were based on May 2006 raw labor rates for the Manufacturing
Sector (NAICS 31 thru 34), loaded using an overhead factor of 110
percent, and indexed to June 2007 using the Employment Cost Index.  The
resulting rates are $115.12 for management personnel, $77.77 for
technical personnel, and $30.58 for clerical personnel.  These values
were taken from the Bureau of Labor Statistics (BLS) Occupational
Employment Statistics Survey website and reflect the latest values
available (May 2006).  The Employment Cost Index is located at:
http://www.bls.gov/news.release/eci.t02.htm.  Table 1 provides a
breakdown of labor hours and associated costs per occurrence for each
activity in each part of the application process for affected sources.

The respondent labor costs are found by multiplying the burden hours
associated with each activity by the hourly rate associated with each
labor type.  In total, the CAA section 112(g) regulations contain an
average labor cost of $316,031 per year.  Table 4 contains the results
of the calculation of labor costs for the respondents.

This ICR does not require any capital or start-up costs for equipment,
machinery, and construction.

Industry applicants submitting CAA section 112(g) applications for
case-by-case MACT determinations must transmit their findings to the
delegated State, local, and Tribal agency, which results in photocopying
and postage costs.  We determined that two types of documents would be
both copied and mailed:  2-ounce letters and 1-pound packages.  The
2-ounce letter would contain 5 pages, and the 1-pound package would
contain 200 pages.  Based on the typical price to copy a page, we used
$0.05 a page as our price per unit cost of copying.  The cost for
mailing a 2-ounce letter and 1-pound package via the United States
Postal Service in Spring 2008 is $0.58 and $4.50, respectively.  We also
assumed that a total of three copies would be made for each letter or
package.  We estimate that each applicant will submit one package (the
permit application) and one letter (response to questions).  Table 5
summarizes the total copying and mailing costs per year.  For industry
respondents, the average cost for copying and postage is $872 per year. 
Therefore, the average total cost to respondents, including labor cost
and copying/postage cost, is $316,903 per year.  Table 6 shows this
breakdown by year.

(ii)	Estimating State, Local, and Tribal Agency Costs

The activities for State, local, and Tribal agencies are divided into
the activities that would take place for the application process as
shown in Table 2.  Wage rates for State, local, and Tribal employees
were retrieved from the BLS website (  HYPERLINK
(http://stats.bls.gov/news.release/archives/ecec_09202007.pdf
http://stats.bls.gov/news.release/archives/ecec_09202007.pdf , Table 4. 
Employer costs per hour worked for employee compensation and costs as a
percent of total compensation:  State and local government workers, by
occupational group and full-time and part-time status, June 2007) and
are as follows:  $33.11 per hour for management labor, $33.22 per hour
for technical labor, and $16.39 per hour for clerical labor.  We added
in the value of total benefits in BLS Table 4.  We chose 20 percent of
the base rate as the percentage of salary that constitutes overhead. 
The addition of benefits and overhead to the hourly rate produces a pay
rate that reflects the true cost to employ a State, Local, or Tribal
agency worker.  Following is a summary of the computed hourly wages for
State, Local, and Tribal agency employees.

 Hourly Labor Rates for State, Local, and Tribal Respondents

Labor Type	Hourly Rate	Benefits

	Overhead

(20 % Salary)	Adjusted Hourly Rate

Management	$33.11	$14.18	$6.62	$53.91

Technical	$33.22	$13.79	$6.64	$53.65

Clerical	$16.39	$10.21	$3.28	$29.88

The State and local labor costs are found by multiplying the burden
hours associated with each activity by the hourly rate associated with
each labor type.  In total, the CAA section 112(g) regulations contain
an average labor cost of $115,503 per year.  Table 4 contains the
results of the calculation of labor costs for the State and local
agencies.

This ICR does not require any capital or start-up costs for equipment,
machinery, and construction.

State, local, and Tribal agencies responding to applications for
case-by-case MACT determinations must transmit their findings to the
applicant, which results in photocopying and postage costs.  Copying and
postage costs were calculated in the same manner as described above.  We
estimate that each State, local, and Tribal agency responding to an
application will send three letters (receipt of complete application
and/or notice of additional information, notice of MACT approval to
source, notice of MACT approval to EPA).  Table 5 summarizes the total
copying and mailing costs per year.  For State, local, and Tribal
agencies, the total average cost for copying and postage is $97 per
year.  Therefore, the average total cost to respondents, including labor
cost and copying/postage cost is $115,600 per year.  Table 6 shows this
breakdown by year.

6(c)	Estimating Agency Burden and Costs

Under the CAA section 112(g) regulations, we serve as in an oversight
capacity and audit approximately 10 percent of all applications
processed by State, local, Tribal agencies, for an average of about 2 to
3 applications per year.  In reviewing and evaluating these
applications, we will carry out the activities listed in section 5(a) of
this ICR.  We retained the same activities and burden hour estimates
used in the previous ICR (ICR Number 1658.04).

Managerial activities are considered 5 percent of the technical hours
while clerical activities are considered 10 percent of the technical
hours.  Table 4 contains the results of the burden hours calculation for
each activity during each year of this ICR.  Overall, the section CAA
112(g) regulations contain an average burden of 84 hours per year for
EPA.

We calculated the hourly rates for EPA employees using information on
annual salaries from the Internet site for the Office of Personnel
Management (  HYPERLINK "http://www.opm.gov/oca/08tables/pdf/RUS.pdf" 
http://www.opm.gov/oca/08tables/pdf/RUS.pdf ; January 2008).  We used
the appropriate pay grade levels for management, technical, and clerical
personnel.  We divided the annual pay rate by 2080, the amount of
working hours during a calendar year, to get the hourly wage rate.  We
then multiplied this rate by 1.6 to produce a pay rate that reflects the
true cost to the Federal government to employ a worker.  The value of
1.6 incorporates the addition of benefits at 40 percent of salary and
the addition of overhead at 20 percent of salary to the hourly rate. 
Following is a summary of the computed wages for EPA personnel.

 Hourly Labor Rates for EPA

Labor Type	Pay Grade	Annual Salary	Hourly Rate	Benefits

(40 % Salary)	Overhead

(20 % Salary)	Adjusted Hourly Rate

Management	GS-15	$107,962	$51.90	$20.76	$10.38	$83.04

Technical	GS-12	$65,315	$31.40	$12.56	$6.28	$50.24

Clerical	GS-6	$33,135	$15.93	$6.37	$3.19	$25.49

The EPA labor costs are found by multiplying the burden hours associated
with each activity by the hourly rate associated with each labor type. 
As shown in Table 4, the average labor cost for the EPA is $4,157
dollars per year.  Copying and postal costs for the EPA were calculated
in the same manner as described in the section 6(b).  We estimate that
EPA will send two letters (questions on the MACT determination, final
review results).  Table 5 presents the total EPA copying and postal
costs.  EPA would spend an annual average of $7 on copying and postage. 
The total cost for EPA, including labor and copying/postal costs, would
be an average of $4,163 per year as shown in Table 6.

6(d)	Estimating the Respondent Universe and Total Burden Costs

All of the CAA section 112(d) standards for listed categories have been
promulgated, with the exception of subpart UUUUU, Electric Utility Steam
Generating Units.  In addition, the MACT standards for the source
categories of polyvinyl chloride and copolymers production; brick and
structural clay products manufacturing; clay ceramics manufacturing; and
industrial, commercial, and institutional boilers and process heaters
have been vacated and are now subject to CAA section 112(g).  We have
estimated the potential universe of sources that could be subject to CAA
section 112(g).

Based on our consultations as described in section 3(c), we learned that
a small proportion of facilities have submitted CAA section 112(g)
applications, even in past years when the universe of potentially
affected sources was larger and included those for which a MACT standard
was planned, but not yet final.  Our State contacts estimated that an
average of 1 to 3 applications per year were actually processed in the
previously approved ICR.  Most of these were for listed source
categories for which no MACT standard had yet been issued.  Therefore,
based only on that estimate, the number of applications would have
decreased in the next ICR clearance period.  In the previous ICR, we
assumed two determinations per year per State.  Consultations for this
draft ICR have identified only 3 section 112(g) determination in 5 EPA
regions over the last 3 years.  Prorating this to all 10 EPA regions
would yield 6 determinations over the last 3 years, or 2 per year.  This
determination represents any major source not included in a source
category listed on the source category list.

However, we are also adding in a number of electric utility steam
generating units (EGUs).  EGUs were added to the section 112(c) source
category list in December 15, 2000 and became subject to section 112(g)
at that time. (See 40 CFR 63.40(c).)   EPA removed EGUs from the source
category list in a rule published on March 29, 2005.  However, On Feb.
8, 2008, the United States Court of Appeals for the District of Columbia
Circuit vacated that rule. (State of New Jersey v. EPA, No. 05-1097) and
thus EGUs are a listed source category and 112(g) applies.  Based on a
review of applications for electric utility steam generation units, we
estimate about  67 EGUs may be subject to section 112(g) determinations
over the next 3 years.  Our estimate may be overly conservative because
there may be issues with respect to applicability of section 112(g) to
certain utilities that we have included in our estimate.

Although sources in the source categories of polyvinyl chloride and
copolymers production; brick and structural clay products manufacturing;
clay ceramics manufacturing; and industrial, commercial, and
institutional boilers and process heaters are potentially subject to
section 112(g) due to the MACT standards vacaturs, we are not aware of
any new or reconstructed major sources over the next 3 years in those
categories that would trigger section 112(g).  

Thus, we have assumed that 2 unspecified major sources will file section
112(g) permit applications per year, plus 67 EGUs over the next 3 years,
for a total of 73 permit applications over the next 3 years.  This
estimate may become smaller if the electric utility MACT is promulgated
or the vacated MACT standards are re-promulgated before the end of 3
years.

We also assume 73 State, local, and agency respondents over the next
three years to review the permit applications, for a total of about 146
respondents.

As shown in Table 4, the total respondent burden is 19,310 hours.  As
shown in Table 6, the total respondent cost is $1,297,510.

6(e)	Bottom Line Burden Hours and Cost

(i)	Respondent Tally

Over the 3-year period of this ICR, the total average annual burden and
labor cost for the respondents resulting from the CAA section 112(g)
regulations are 6,437 hours and $431,534, respectively (see Table 4). 
There are no capital start-up costs associated with this collection. 
Operation and maintenance costs result from photocopying and postage
expenses, which are a total of $969 per year (see Table 5).  The total
average annual cost to respondents is $432,503 (see Table 6).

(ii)	Agency Tally

Over the 3-year period of this ICR, the total average annual burden and
labor cost for EPA is 84 and $4,157, respectively (see Table 4). 
Operation and maintenance costs result from photocopying and postage
expenses, which are a total of $7 per year (see Table 5).  The total
average annual cost to EPA is $4,163 (see Table 6).

6(f)	Reasons for Change in Burden

The currently approved reporting and recordkeeping hour burden, based on
ICR Number 1658.04, is 36,800 hours per year.  We are requesting a
decrease in burden to 6,437 hours per year.  The difference, 30,363
hours, is due to a program adjustment.  The following discussion
explains these changes.

Primarily, the change in burden is due to completion of setting MACT
standards for the source category list (with the exception of the
vacaturs and EGUs).  Therefore, our revised estimate of burden is
smaller than that estimated in the last ICR.

We are also requesting a decrease in the reporting and recordkeeping
cost burden due to the decrease of photocopying and postage costs for
the CAA section 112(g) applications as part of annual operation and
maintenance (O&M) costs.  Our assumptions for copying and postage costs
are discussed in section 6(b).  The total annual copying and postage
costs for respondents is $969, a decrease from the previous estimate of
$3,930 per year.

6(g)	Burden Statement

The annual public reporting and recordkeeping burden for this
collection of information is estimated to average 134 hours per
response.  Burden means the total time, effort, or financial resources
expended by persons to generate, maintain, retain, or disclose or
provide information to or for a Federal agency.  This includes the time
need to review instructions; develop, acquire, install, and utilize
technology and systems for the purposes of collecting, validating, and
verifying information, processing and ways to comply with any previously
applicable instructions and requirements; train personnel to be able to
respond to a collection of information; search data sources; complete
and review the collection of information; and transmit or otherwise
disclose the information.  An agency may not conduct or sponsor, and a
person is not required to respond to, a collection of information unless
it displays a currently valid OMB control number.  The OMB control
numbers for EPA's regulation are listed in 40 CFR part 9 and 48 CFR
Chapter 15.

To comment on the Agency's need for this information, the accuracy of
the provided burden estimates, and any suggested methods for minimizing
respondent burden, including the use of automated collection techniques,
EPA has established a public docket for this ICR under Docket ID Number
EPA-HQ-OAR-2004-0073, which is available for online viewing at  
HYPERLINK "http://www.regulations.gov"  www.regulations.gov , or in
person viewing at the Air and Radiation Docket and Information Center in
the EPA Docket Center (EPA/DC), EPA West, Room 3334, 1301 Constitution
Avenue, NW, Washington, D.C.  The EPA Docket Center Public Reading Room
is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding
legal holidays.  The telephone number for the Reading Room is (202)
566-1744, and the telephone number for the Air and Radiation Docket and
