ENVIRONMENTAL PROTECTION AGENCY

NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR part
60, subpart PPP) and NESHAP for Wool Fiberglass Manufacturing (40 CFR
part 63, subpart NNN) (Renewal)

1.  Identification of the Information Collection

1(a)  Title of the Information Collection

NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR part
60, subpart PPP) and NESHAP for Wool Fiberglass Manufacturing (40 CFR
part 63, subpart NNN) (Renewal),

EPA ICR Number 1160.09, OMB Control Number 2060-0114

1(b)  Short Characterization/Abstract

This Information Collection Request (ICR) includes two Clean Air Act
(CAA) standards for the wool fiberglass manufacturing industry.  Both
the New Source Performance Standards (NSPS) and National Emission
Standards for Hazardous Air Pollutants (NESHAP) standards include: basic
recordkeeping and reporting, including initial notifications;
performance testing; semiannual excess emission reports; and occurrence
and duration of any startup, shutdown, or malfunction in the operation
of an affected facility.  All reports are sent to the delegated state or
local authority.  In the event that there is no such authority, the
reports are sent directly to the EPA regional office.

The NSPS for Wool Fiberglass Insulation Manufacturing Plants, published
at 40 CFR part 60, subpart PPP, were proposed on February 7, 1984 and
promulgated on February 25, 1985.  These regulations apply to each
rotary spin (RS) wool fiberglass insulation manufacturing line, which
commenced construction, modification, or reconstruction after February
2, 1984.  The purpose of this NSPS is to control the emissions of
particulate matter from each RS wool fiberglass insulation manufacturing
line.  The standards limit particulate emissions to 5.5 kilograms per
megagram (11.0 lb./ton) of molten glass used to manufacture the product.

The NESHAP for Wool Fiberglass Manufacturing, published at 40 CFR part
63, subpart NNN, were proposed on March 31, 1997 and promulgated on June
14, 1999.  These regulations apply to each glass melting furnace located
at a wool fiberglass manufacturing plant; each RS manufacturing line
producing building insulation; each new and existing flame attenuation
(FA) manufacturing line that produces pipe products; and each new FA
manufacturing line that produces heavy density products.  Plants that
manufacture mineral wool from rock or slag are not subject to the
proposed rule, but they are subject to a separate NESHAP standard for
mineral wool production.  A facility that is determined to be an area
source would not be subject to this NESHAP standard.  This information
is being collected to assure compliance with 40 CFR part 60, subpart PPP
and 40 CFR part 63, subpart NNN.

In general, all NSPS and NESHAP standards require initial notifications,
performance tests, and periodic reports.  Owners or operators are also
required to maintain records of the occurrence and duration of any
startup, shutdown, or malfunction in the operation of an affected
facility or any period during which the monitoring system is
inoperative.  These notifications, reports, and records are essential in
determining compliance and are required of all sources subject to both
the NSPS and NESHAP.

Any owner or operator subject to the provisions of 40 CFR part 60,
subpart PPP shall maintain a file of these measurements and retain the
file for at least two years following the date of such measurements,
maintenance reports, and records.  Any owner or operator subject to the
provisions of 40 CFR part 63, subpart NNN shall maintain a file of these
measurements and retain the file for at least five years following the
date of such measurements, maintenance reports, and records.  All
reports for both the NSPS and NESHAP are sent to the delegated state or
local authority.  In the event that there is no such delegated
authority, the reports are sent directly to the appropriate U.S.
Environmental Protection Agency (EPA) regional office.

Approximately 32 sources are currently subject to 40 CFR part 60,
subpart PPP.  Approximately 29 sources are subject to 40 CFR part 63,
subpart NNN.  It is anticipated that no new sources will become subject
to either the NSPS or NESHAP regulation in the next three years.  The
number of affected sources subject to these regulations was estimated
based on information available from the North American Insulation
Manufacturing Association (NAIMA).

	The Office of Management and Budget (OMB) approved the currently active
ICR without any “Terms of Clearance.”

	The burden to the “Affected Public” may be found below in both
Table 1: Annual Respondent Burden: NSPS for Wool Fiberglass Insulation
Manufacturing Plants (40 CFR part 60, subpart PPP) (Renewal) and Table
2: Annual Respondent Burden: NESHAP for Wool Fiberglass Manufacturing
(40 CFR part 63, subpart NNN) (Renewal).  

The burden to the “Federal Government” is attributed entirely to
work performed by Federal employees or government contractors.  This
burden may be found below in both Table 3: Average Annual EPA Burden:
NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR part
60, subpart PPP) (Renewal) and Table 4: Average Annual EPA Burden:
NESHAP for Wool Fiberglass Manufacturing (40 CFR part 63, subpart NNN)
(Renewal).

2.  Need for and Use of the Collection

2(a)  Need/Authority for the Collection

The EPA is charged under section 111 of the Clean Air Act, as amended,
to establish standards of performance for new stationary sources that
reflect: 

. . . application of the best technological system of continuous
emissions reduction which (taking into consideration the cost of
achieving such emissions reduction, or any non-air quality health and
environmental impact and energy requirements) the Administrator
determines has been adequately demonstrated.  Section 111(a)(l).

The Agency refers to this charge as selecting the best demonstrated
technology (BDT).  Section 111 also requires that the Administrator
review and, if appropriate, revise such standards every four years.

The EPA also is charged under section 112 of the Clean Air Act, as
amended, to establish standards of performance for each category or
subcategory of major sources and area sources of hazardous air
pollutants (HAPs).  These standards are applicable to new or existing
sources of hazardous air pollutants and shall require the maximum degree
of emissions reduction.

In addition, section 114(a) states that the Administrator may require
any owner or operator subject to any requirement of this Act to: 

(A) Establish and maintain such records; (B) make such reports; (C)
install, use, and maintain such monitoring equipment, and use such audit
procedures, or methods; (D) sample such emissions (in accordance with
such procedures or methods, at such locations, at such intervals, during
such periods, and in such manner as the Administrator shall prescribe);
(E) keep records on control equipment parameters, production variables
or other indirect data when direct monitoring of emissions is
impractical; (F) submit compliance certifications in accordance with
Section 114(a)(3); and (G) provide such other information as the
Administrator may reasonably require.

In the Administrator's judgment, particulate emissions and hazardous air
pollutant (HAP) emissions from wool fiberglass manufacturing plants
cause or contribute to air pollution that may reasonably be anticipated
to endanger public health or welfare.  Therefore, the NSPS and NESHAP
were promulgated for this source category at 40 CFR part 60, subpart PPP
and 40 CFR part 63, subpart NNN, respectively.

2(b)  Practical Utility/Users of the Data

The control of emissions of particulates and HAPs from wool fiberglass
manufacturing plants requires not only the installation of properly
designed equipment but also the operation and maintenance of that
equipment.  Emissions of particulates from wool fiberglass insulation
manufacturing plants are the result of operation of each RS wool
fiberglass insulation manufacturing line.  Emissions of HAPs from wool
fiberglass manufacturing plants are the result of operation of each
glass melting furnace and each RS and FA manufacturing line.  These
standards rely on the capture of particulate and HAPs emissions by
control equipment such as a wet scrubbing control device or an
electrostatic precipitator.  The notifications required in the
applicable regulations are used to inform the Agency or delegated
authority when a source becomes subject to the requirements of the
regulations.  The reviewing authority may then inspect the source to
check if the pollution control devices are properly installed and
operated and the regulations are being met.  Performance test reports
are needed as these are the Agency’s record of a source's initial
capability to comply with the emission standards and serve as a record
of the operating conditions under which compliance was achieved.  The
semiannual reports are used for problem identification, as a check on
source operation and maintenance, and for compliance determinations. 
The information generated by the monitoring, recordkeeping and reporting
requirements described in this ICR is used by the Agency to ensure that
plants affected by the NSPS and/or NESHAP continue to operate the
control equipment and achieve compliance with the regulation.  Adequate
monitoring, recordkeeping, and reporting are necessary to ensure
compliance with the applicable regulations, as required by the Clean Air
Act.  The information collected from recordkeeping and reporting
requirements is also used for targeting inspections and is of sufficient
quality to be used as evidence in court.

3.  Non-duplication, Consultations, and Other Collection Criteria

The requested recordkeeping and reporting are required under both 40 CFR
part 60, subpart PPP and 40 CFR part 63, subpart NNN.

3(a)  Non-duplication

If the subject standards have not been delegated, the information is
sent directly to the appropriate EPA regional office.  Otherwise, the
information is sent directly to the delegated state or local agency.  If
a state or local agency has adopted its own similar standards to
implement the Federal standards, a copy of the report submitted to the
state or local agency can be sent to the Administrator in lieu of the
report required by the Federal standards.  Therefore, no duplication
exists.

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

An announcement of a public comment period for the renewal of this ICR
was published in the Federal Register at 74 FR 38004 on July 30, 2009. 
No comments were received on the burden published in the Federal
Register.

3(c)  Consultations

Information provided by the North American Insulation Manufacturing
Association (NAIMA) in preparation of the most recent approved ICR was
used as the primary source for determining the number of affected
sources subject to these standards.

	Industry trade associations and other interested parties were provided
an opportunity to comment on the burden associated with the standard as
it was being developed and the standard has been previously reviewed to
determine the minimum information needed for compliance purposes.

It is our policy to carefully review any comments received since the
last ICR renewal including those submitted in response to the first
Federal Register notice, and to respond appropriately.

 

3(d)  Effects of Less Frequent Collection

Less frequent information collection would decrease the margin of
assurance that plants are continuing to meet the standards. 
Requirements for information gathering and recordkeeping are useful
techniques to ensure that good operation and maintenance practices are
applied and emission limitations are met.  If the information required
by these standards was collected less frequently, the likelihood of
detecting poor operation and maintenance of control equipment and
noncompliance would decrease.

3(e)  General Guidelines

None of these reporting or recordkeeping requirements violate any of the
regulations established by OMB at 5 CFR 1320.5.

3(f)  Confidentiality

The required information has been determined not to be confidential. 
However, any information submitted to the Agency for which a claim of
confidentiality is made will be safeguarded according to the Agency
policies set forth in title 40, chapter 1, part 2, subpart B -
Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR
36902, September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43
FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979).

3(g)  Sensitive Questions

None of the reporting or recordkeeping requirements contains sensitive
questions.

4.  The Respondents and the Information Requested

4(a)  Respondents/SIC Codes

The respondents to the recordkeeping and reporting requirements for 40
CFR part 60, subpart PPP and 40 CFR part 63, subpart NNN are wool
fiberglass manufacturing plants.  The United States Standard Industrial
Classification (SIC) code for the respondents affected by the standards
is 3296, which corresponds to the North American Industry Classification
System (NAICS) code 327993.

4(b)  Information Requested 

(i)  Data Items

The 40 CFR part 63, subpart NNN standards require affected facilities to
maintain all records, including reports and notifications for at least
five years.  This is consistent with the General Provisions as applied
to the standards.  EPA believes that the five-year records retention
requirement is consistent with the part 70 permit program and the
five-year statute of limitations on which the permit program is based. 
Also, the retention of records for five years would allow EPA to
establish the compliance history of a source and any pattern of
compliance for purposes of determining the appropriate level of
enforcement action.  Historically, EPA has found that the most flagrant
violators frequently have violations extending beyond the five years. 
EPA would be prevented from pursuing the worst violators due to the
destruction or nonexistence of records if records were retained for less
than five years.

The 40 CFR part 60, subpart PPP standards require affected facilities to
maintain all records, including reports and notifications for at least
two years.

All data in this ICR that is recorded and/or reported is required by 40
CFR part 60, subpart PPP and/or 40 CFR part 63, subpart NNN.  A source
subject to 40 CFR part 60, subpart PPP and/or 40 CFR part 63, subpart
NNN must comply with the notifications, monitoring, and recordkeeping
requirements listed in the following exhibits.

Recordkeeping for 40 CFR part 60, subpart PPP

Startups, shutdowns, malfunctions, and periods where the continuous
monitoring system is inoperative	60.7(b)

Records are required to be retained for two years	60.7(f)

Continuous measurements of control device operating parameters	60.684(d)

Recordkeeping for 40 CFR part 63, subpart NNN

General recordkeeping requirements (e.g., startups, shutdowns, and
malfunctions including process equipment, air pollution control
equipment, maintenance performed, and actions taken outside the scope of
the existing plans)	63.10(b)(2), 63.1386(d)

Continuous measurements of control device operating parameters:

- Bag leak detection system alarms

- ESP parameter values used to measure performance

- Air temperature above the molten glass in a cold top furnace

- Uncontrolled glass-melting furnace parameter values to measure
performance

- The formulation of each binder patch and the LOI and density for each
product manufactured

- Process parameter levels for RS and FA manufacturing lines that use
process modifications to comply with the emission limits

- Scrubber pressure drop, scrubbing liquid flow rate, and any chemical
additive

- Incinerator operating temperature and the results from periodic
inspection of incinerator components

- Glass pull rate	63.1386(d)(2)(i-ix)

Some of the respondents are using monitoring equipment that
automatically records parameter data.  Although personnel at the
affected facility must still evaluate the data, internal automation has
significantly reduced the burden associated with monitoring and
recordkeeping at a plant site.  

	Also, regulatory agencies in cooperation with the respondents continue
to create reporting systems to transmit data electronically.  However,
electronic reporting systems are still not widely used.  At this time,
it is estimated that approximately 10 percent of the respondents use
electronic reporting.

(ii)  Respondent Activities

Respondent Activities

Read instructions.

Install, calibrate, maintain, and operate continuous monitoring system
for 40 CFR part 63, subpart NNN sources.  Install, calibrate, maintain,
and operate CMS for pressure drop and liquid supply pressure for wet
scrubber for 40 CFR part 60, subpart PPP sources.

Perform initial performance test.  Methods 1-5, 316 or 318; method for
determining LOI; method for determining free-formaldehyde content of
resin; and method for the determination of product density are used for
40 CFR part 63, subpart NNN sources.  Reference Method 5E for
particulates is used 40 CFR part 60, subpart PPP sources.  All tests are
repeated if necessary.

5.  The Information Collected: Agency Activities, Collection
Methodology, and Information Management

5(a)  Agency Activities 

EPA conducts the following activities in connection with the
acquisition, analysis, storage, and distribution of the required
information.

Agency Activities

Observe initial performance tests and repeat performance tests if
necessary.

Review notifications and reports, including performance test reports,
and excess emissions reports required to be submitted by industry.

Audit facility records.

Input, analyze, and maintain data in the Air Facility System (AFS).

5(b)  Collection Methodology and Management

Following notification of startup, the reviewing authority might inspect
the source to determine whether the pollution control devices are
properly installed and operated.  Performance test reports are used by
the Agency to discern a source’s initial capability to comply with the
emission standard.  Data and records maintained by the respondents are
tabulated and published for use in compliance and enforcement programs. 
The semiannual reports are used for problem identification, as a check
on source operation and maintenance, and for compliance determinations.

Information contained in the reports is entered into the AFS, which is
operated and maintained by the EPA Office of Compliance.  AFS is the EPA
database for the collection, maintenance, and retrieval of compliance
and annual emission inventory data for more than 100,000 industrial and
government-owned plants.  EPA uses the AFS for tracking air pollution
compliance and enforcement by local and state regulatory agencies and
EPA regional offices and EPA Headquarters.  EPA and its delegated
Authorities can edit, store, retrieve, and analyze the data.

The records required by 40 CFR part 60, subpart PPP must be retained by
the owner or operator for two years.  The records required by 40 CFR
part 63, subpart NNN must be retained by the owner or operator for five
years.

5(c)  Small Entity Flexibility

There are no small businesses affected by this regulation.  According to
the Wool Fiberglass Insulation Manufacturing Industry – Background
Information for Proposed Standards (EPA-450/3-82-022a):  “The Small
Business Administration (SBA) definition of a small business for SIC
code 3296 Mineral Wool is 750 employees.  All of the four publicly held
firms that manufacture wool fiberglass insulation have more than 750
employees.  Therefore, none of the firms meets the SBA definition of a
small business.”

5(d)  Collection Schedule

The specific frequency for each information collection activity within
this request is shown below in both Table 1: Annual Respondent Burden:
NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR part
60, subpart PPP) (Renewal) and Table 2: Annual Respondent Burden: NESHAP
for Wool Fiberglass Manufacturing (40 CFR part 63, subpart NNN)
(Renewal).

6.  Estimating the Burden and Cost of the Collection

 	Tables 1 and 2 document the computation of individual burdens for the
recordkeeping and reporting requirements applicable to the industry for
the subparts included in this ICR.  The individual burdens are expressed
under standardized headings believed to be consistent with the concept
of burden under the Paperwork Reduction Act.  Responses to this
information collection are mandatory.  The 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.

6(a)  Estimating Respondent Burden

The average annual burden to industry over the next three years from
these recordkeeping and reporting requirements for 40 CFR part 60,
subpart PPP is estimated to be 2,631 hours.    The average annual burden
to industry over the next three years from these recordkeeping and
reporting requirements for 40 CFR part 63, subpart NNN is estimated to
be 15,928 hours.       The total number of labor hours for both subparts
is 18,559.  These hours are based on Agency studies and background
documents from the development of the regulation; Agency knowledge and
experience with the NSPS and NESHAP programs; the previously approved
ICR; and any comments received.

6(b)  Estimating Respondent Costs

(i)  Estimating Labor Costs 

This ICR uses the following labor rates: $114.77 per hour for Executive,
Administrative, and Managerial labor; $97.59 per hour for Technical
labor, and $48.26 per hour for Clerical labor.  These rates are from the
United States Department of Labor, Bureau of Labor Statistics, March,
2009, “Table 2.  Civilian workers, by occupational and industry
group”.  The rates are from column 1, “Total compensation”.  The
rates have been increased by 110 percent to account for the benefit
packages available to those employed by private industry.

Managerial	$114.77 ($54.65 + 110%)

Technical	$97.59	($46.47 + 110%)

Clerical	$48.26 	($22.98 + 110%)

Managerial and administrative labor hours for 40 CFR part 60, subpart
PPP and 40 CFR part 63, subpart NNN were estimated to be approximately 5
percent and 10 percent, respectively, of the estimated technical labors.
 

(ii)  Estimating Capital/Startup and Operation and Maintenance Costs

	The capital/startup costs and operations and maintenance (O&M) costs
for 40 CFR part 60, subpart PPP are associated with the particulate
matter monitoring equipments.  The capital/startup costs are one-time
costs when the facility becomes subject to the standard.  Because no new
sources are anticipated for this source category over the next three
years, the capital startup costs are zero.  The annual O&M costs
associated with the particulate monitoring equipment are $16,500.

The capital and O&M costs for 40 CFR part 63, subpart NNN are associated
with baghouse leak detection monitoring, furnace temperature monitoring,
and formaldehyde emission monitoring.  The capital/startup costs are
one-time costs when a facility becomes subject to the standard.  Because
no new sources are anticipated for this source category over the next
three years, the capital startup costs are zero.  O&M costs for baghouse
leak detection monitoring are estimated at $500 per year per baghouse. 
There are no O&M costs associated with furnace temperature monitors or
formaldehyde emissions monitoring.

Furnace Temperature Monitoring	$1,500	0	0	$0	15	$0

Formaldehyde Emission Monitoring	$15,000	0	0	$0	50	$0

Because there are no new sources expected over the next three years,
there are no capital costs associated with either 40 CFR part 60,
subpart PPP or 40 CFR part 63, subpart NNN.

The total O&M cost for this ICR is $488,500.  This is the sum of the
totals of column G in the two tables above.

	The total respondent cost has been calculated as the addition of the
capital/startup costs and the annual O&M costs.  The average annual cost
for capital/startup and O&M to industry over the next three years of the
ICR is estimated to be $488,500.

6(c)  Estimating Agency Burden and Cost

The only costs to the Agency are those costs associated with analysis of
the reported information.  EPA's overall compliance and enforcement
program includes activities such as the examination of records
maintained by the respondents, periodic inspection of sources of
emissions, and the publication and distribution of collected
information.

The average annual Agency cost during the three years of the ICR for 40
CFR part 60, subpart PPP is estimated to be $6,535.  

The average annual Agency cost during the three years of the ICR for 40
CFR part 63, subpart NNN is estimated to be $22,504.  

This cost is based on the average hourly labor rate as follows:

	Managerial	$61.  36 (GS-13, Step 5, $38.35 + 60%)

	Technical	$45.52 (GS-12, Step 1, $28.45 + 60%)

	Clerical	$24.64 (GS-6, Step 3, $15.40 + 60%)

These rates are from the Office of Personnel Management (OPM), 2009
General Schedule, which excludes locality rates of pay.  The rates have
been increased by 60 percent to account for the benefit packages
available to government employees.  Details upon which this estimate is
based appear below in both Table 3: Average Annual EPA Burden: NSPS for
Wool Fiberglass Insulation Manufacturing Plants (40 CFR part 60, subpart
PPP) (Renewal) and Table 4: Average Annual EPA Burden:  NESHAP for Wool
Fiberglass Manufacturing (40 CFR part 63, subpart NNN) (Renewal). 
Managerial and administrative labor hours were estimated to be
approximately 5 percent and 10 percent, respectively, of the estimated
technical labors.  

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

Approximately 32 and 29 sources currently are subject to 40 CFR part 60,
subpart PPP and 40 CFR part 63, subpart NNN, respectively.  We estimate
that no additional sources per year will become subject to either
regulation in the next three years.

Respondent Universe and Number of Responses Per Year

40 CFR part 60, subpart PPP	0	5	32	2	0	64

40 CFR part 63, subpart NNN	0	8	29	4	0	116

The number of total respondents for 40 CFR part 60, subpart PPP and 40
CFR part 63, subpart NNN is 61.  This number is the sum of column A and
column C of the Respondent Universe and Number of Responses per Year
table.  This represents the number of existing sources plus the number
of new sources averaged over the three-year period (i.e., the total of
the number of new respondents over the three-year period divided by
three years).

	The number of Total Annual Responses for both 40 CFR part 60, subpart
PPP and 40 CFR part 63, subpart NNN is 180.  This is the sum of column F
of the Respondent Universe and Number of Responses per Year table above.

The total annual labor costs for 40 CFR part 60, subpart PPP is
$247,457.  The total annual labor costs for 40 CFR part 63, subpart NNN
is $1,497,983.  The total annual labor costs for both standards are
equal to $1,745,440.  Details upon which this estimate is based below
appear in both Table 1: Annual Respondent Burden: NSPS for Wool
Fiberglass Insulation Manufacturing Plants (40 CFR part 60, subpart PPP)
(Renewal) and Table 2: Annual Respondent Burden: NESHAP for Wool
Fiberglass Manufacturing (40 CFR part 63, subpart NNN) (Renewal).

Note that the total annual capital and O&M costs to the regulated entity
are $488,500.  These costs are detailed in section 6(b)(iii),
Capital/Startup vs. Operation and Maintenance Costs.

6(e)  Bottom Line Burden Hours and Cost Tables

The bottom line burden hours and cost tables for both the Agency and the
respondents appear in the attached Tables 1 thru 4.  A summary of the
bottom line burden hours and costs appears below.

	Industry Burden	Agency Burden	Capital Costs	O&M Costs

	Hours	Dollars ($)	Hours	Dollars ($)	Dollars ($)	Dollars ($)

40 CFR Part 60, Subpart PPP	2,631	$247,457	147	$6,535	0	$478,500

Total	18,559	$1,745,440	635	$29,039	0	$488,500

6(f)  Reasons for Change in Burden

There is an increase of 343 hours in the total labor hours for this ICR,
due to an adjustment.  Total labor hours for this ICR are 18,559 rather
than 18,216 in the previous ICR because the previous ICR did not include
managerial and clerical hours for 40 CFR part 60, subpart PPP.  This
adjustment also results in a slight increase in the per-respondent labor
hours, from 101 to 103 hours per response.  

Although these adjustments resulted in an increase in calculated burden
hours, the regulations have not changed over the past three years and
are not anticipated to change over the next three years.  Additionally,
the growth rate for the respondents is very low, negative or
non-existent.  

There is an increase in both respondent and Agency costs resulting from
labor rate increases from 2003 to 2009.  This ICR uses 2009 labor rates
because burden and cost calculations in this ICR were expanded to
include managerial and clerical labor rates, and the previous ICR only
provided a technical labor rate for 2003.  This ICR is therefore updated
to present the most recent available labor rates for each of the three
labor categories.  

An apparent difference of $500 in O&M costs is attributable to rounding
to the nearest thousand in the previous renewal; this ICR renewal
presents more exact figures.

6(g)  Burden Statement

The annual public reporting and recordkeeping burden for this collection
of information is estimated to average 103 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 needed to review
instructions; develop, acquire, install, and utilize technology and
systems for the purposes of collecting, validating, and verifying
information, processing and maintaining information, and disclosing and
providing information; adjust the existing 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 valid OMB
Control Number.  The OMB Control Numbers for EPA’s regulations are
listed at 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-OECA-2009-0530.  An electronic version of the public docket is
available at http://www.regulations.gov/ which may be used to obtain a
copy of the draft collection of information, submit or view public
comments, access the index listing of the contents of the docket, and to
access those documents in the public docket that are available
electronically.  When in the system, select “search,” then key in
the docket ID number identified in this document.  The documents also
are available for public viewing at the Enforcement and Compliance
Docket and Information Center in the EPA Docket Center (EPA/DC), EPA
West, Room 3334, 1301 Constitution Avenue, NW, Washington, DC.  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
docket center is (202) 566-1752.  Also, you can send comments to the
Office of Information and Regulatory Affairs, Office of Management and
Budget, 725 17th Street, NW, Washington, DC 20503, Attention: Desk
Officer for EPA.  Please include the EPA Docket ID Number
EPA-HQ-OECA-2009-0530 and OMB Control Number 2060-0114 in any
correspondence.

 Part B of the Supporting Statement

 

 40 CFR part 63, subpart NNN also includes plants that manufacture
fiberglass for liquid and air filtration.   However, the majority of the
plants (90 percent) manufacture fiberglass for building insulation.  

 In order to calculate O&M costs for 40 CFR part 63, subpart NNN, the
estimates provided in column F were not based on the number of
respondents but, instead, based on the total number of continuous
monitoring devices that exist within the industry.  For example, we
estimate that there are 20 baghouses used within the wool fiberglass
manufacturing industry.  Some respondents may have more than one
baghouse located at their facility.
