NSPS for Ammonium Sulfate Manufacturing Plants 

1.  Identification of the Information Collection

1(a)  Title of the Information Collection

NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR part 60, subpart
PP) (Renewal)

1(b)  Short Characterization/Abstract

The New Source Performance Standards (NSPS) for Ammonium Sulfate
Manufacturing Plants were proposed on February 4, 1980, and promulgated
on November 12, 1980.  These standards apply to each ammonium sulfate
dryer within an ammonium sulfate manufacturing plant in the caprolactam
by-product, synthetic, and coke oven by-products sectors of the ammonium
sulfate manufacturing industry for which construction, modification or
reconstruction commenced after the date of the proposal.

Owners or operators of the affected facilities described must make the
following 

one-time-only reports: notification of the date of construction or
reconstruction; notification of the anticipated and actual dates of
startup; notification of any physical or operational change to an
existing facility which may increase the regulated pollutant emission
rate; and the notification of the date of the initial performance test. 
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.  These notifications, reports and
records are required, in general, of all sources subject to NSPS.

Recordkeeping requirements specific to the ammonium sulfate industry
provides information on the amount of ammonium sulfate processed and the
operation of the emission control device.  Owners or operators of
affected facilities are required to install, calibrate, maintain, and
operate a flow monitoring device which can be used to determine the
mass-flow of ammonium sulfate feed material to the process, and which
has an accuracy of ( 5 percent across its operating range.  However, if
the plant uses weight scales of the same accuracy to directly measure
production rates of ammonium sulfate, the use of flow monitoring devices
is not required.  Owners or operators of all affected facilities will
install, calibrate, maintain, and operate a monitoring device which
continuously measures and permanently records the total pressure drop
across the emission control system.

Therefore, the recordkeeping requirements for ammonium sulfate plants
consist of the occurrence and duration of all startups and malfunctions
as described, the initial performance test results, amount of ammonium
sulfate feed material, and the pressure drop across the emission control
system.  Records of startups, shutdowns and malfunctions will be noted
as they occur.  Records of the performance test should include
information necessary to determine the conditions of the performance
test, and performance test measurements (including pressure drop across
the emission control system) and results.  The Continuous Monitoring
System (CMS) will record pressure drop across the scrubbers continuously
and automatically.

The reporting requirements for this industry include the initial
notifications listed and the initial performance test results.  All
reports 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 Environmental Protection Agency (EPA) regional Office. 
Notifications are used to inform the Agency or delegated authority when
a source becomes subject to the standard.  The reviewing authority may
then inspect the source to ensure that the pollution control devices are
properly installed and operated, and the standard is being met. 
Performance test records are needed as these are the Agency's records of
a source's initial capability to comply with the emission standard.

Owners or operators of the affected facilities described are required to
adhere to reporting requirements specific to this rule, e.g., provide
information on the operation of emissions control devices.  Semiannual
excess emissions and monitoring systems reports are required to be
submitted by the respondents.

Any owner or operator subject to the provisions of this part will
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.  These records and reports are essential in determining
compliance, and are required of all sources subject to NSPS.

Based on the pre-existing number of applicable sources, approximately
two sources are currently subject to the regulations.  Due to the static
nature of the industry, it is estimated that no additional sources will
become subject to the standard over the next three years.  This
information is based on discussions with EPA personnel knowledgeable
about the ammonium sulfate industry.  The industry is dominated by
facilities that have been operating since prior to the proposed date of
the rule (February 4, 1980), and there has been a long-term static or
declining market for the product both domestically and globally.  The
average annual cost to industry over the next three years of this
Information Collection Request (ICR) is estimated to 

be $15,808.

The Office of Management and Budget (OMB) approved the current
Information Collection Request (ICR) without any “Terms of
Clearance.”

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 (CAA), 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.

In the Administrator's judgment, particulate emissions from the ammonium
sulfate manufacturing industry causes or contribute to air pollution
that may reasonably be anticipated to endanger public health or welfare.
 Therefore, the NSPS were promulgated for this source category at 40 CFR
part 60, subpart PP.

2(b)  Practical Utility/Users of the Data

The control of emissions of particulate from ammonium sulfate facilities
requires not only the installation of properly designed equipment, but
also the operation and maintenance of that equipment.  Emissions of
particulate from ammonium sulfate facilities are the result of the
operation of the affected facilities.  The subject standards are
achieved by the reduction of particulate emissions using control
technology and leak detection and repair procedures.  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
ensure that the pollution control devices are properly installed and
operated and leaks are being detected and repaired, and the regulations
are 

being met.

Performance test reports are needed as these are the Agency’s records
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 information generated by the (monitoring,
recordkeeping and reporting) requirement described in this ICR is used
by the Agency to ensure that facilities which are affected by NSPS
continue to operate the control equipment in 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.  Nonduplication, Consultations, and Other Collection Criteria

The requested recordkeeping and reporting are required under 40 CFR
Part 60, 

subpart PP.

3(a)  Nonduplication

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 their own similar standards to
implement the Federal standards, a copy of the report submitted to the
state or local agencies 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 on June 21, 2006 (71 FR 35652). 
No comments were received on the burden published in the Federal
Register.

3(c)  Consultations

For this information collection, the previous ICR renewal was used to
obtain burden estimates since this ICR renewal was processed under the
“renew without change” option.  Per this guidance, all data and
assumptions from the previous ICR renewal were used as the basis for
estimating the hourly and cost burdens associated with this renewal.  

The most recent ICR renewal used several different resources to obtain
the most recent data available for ammonium sulfate manufacturing
plants.  We referenced the most recent ICR and the preparer of the
active ICR.  We also accessed the most recent data (October 30, 2003)
available on the AIRS Facility Subsystem (AFS) database as maintained by
the Office of Compliance.  We reviewed information available from the
Office of Compliance Sector Notebook “Profile of the Inorganic
Chemical Industry,” the United States Census Bureau via the Internet,
and other web sites covering ammonium sulfate manufacturing.  We
consulted with EPA’s Office of Air Quality Planning and Standards,
Information Transfer and Program Integration Division.  In addition, we
contacted the American Agricultural Economics Association (AAEA), Kay
Snopek, (515) 233-3202, American Chemical Society, Hank Whalen, (202)
872-8724, Costal Chemical, Ms. Barbara Cabot, (307) 637-2700, Agrium,
Mr. Robert Williams, (559) 627-5553, Florida Department of Environmental
Protection (FCEP), Ms. Cindy Phillips, (850) 921-9534, and BP Chemicals,
Incorporated, Mr. Kevin Sprague, (419) 226-1200.

3(d)  Effects of Less Frequent Collection

Less frequent information collection would decrease the margin of
assurance that facilities are continuing to meet the standards. 
Requirements for information gathering and recordkeeping is useful
technique 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 Part 1320, Section 1320.5.

3(f)  Confidentiality

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 contain sensitive
questions.

4.  The Respondents and the Information Requested

4(a)  Respondents/SIC Codes

The respondents to the recordkeeping and reporting requirements are
ammonium sulfate manufacturing facilities.  The United States Standard
Industrial Classification (SIC) code for the respondents affected by the
standards is 2873 which corresponds to the North American Industry
Classification System (NAICS) code 325311 for ammonium sulfate
manufacturing facilities.

4(b)  Information Requested

None of these reporting or recordkeeping requirements violate any of the
regulations established by OMB at 5 CFR part 1320, section 1320.5.

(i)  Data Items

All data in this ICR that is recorded and/or reported is required by New
Source Performance Standards, (NSPS) for Ammonium Sulfate Manufacturing
Plants (40 CFR part 60, 

subpart PP).

A source must make the following reports:

Notification Reports	Standard Citation by Section

Notification of construction or modification	60.7(a)(1)

Notification of initial startup	60.7(a)(3)

Notification of initial performance test	60.8(d)

Periodic Reports	Standard Citation by Section

Semiannual report	60.7(c)

A source must make the following reports:

Recordkeeping

Initial performance test results	60.8(a) 

Startup, shutdowns, and malfunctions	60.8(c)

Control device operating parameters (continuous)	60.423

Records should be retained for two years	60.7(f)

Electronic Reporting

Currently, sources are using monitoring equipment that provides
parameter data in an automated way, e.g., a pressure drop and volumetric
flow rate.  Although personnel at the source still need to evaluate the
data, this type of monitoring equipment has significantly reduced the
burden associated with monitoring and recordkeeping.  In addition, some
Regulatory Agencies are setting up electronic reporting systems to allow
sources to report electronically which is reducing the reporting burden.
 However, electronic reporting systems are still not widely used by the
regulatory Agencies.  It is estimated that approximately 10% of the
respondents use electronic reporting.

(ii)  Respondent Activities

Respondent Activities

Read instructions.

Install, calibrate, maintain, and operate control devices for PM.

Perform initial performance test, Reference Methods 9 and 5, and repeat
performance tests if necessary.

Write the notifications and reports listed above.

Enter information required to be recorded above.

Submit the required reports developing, acquiring, installing, and
utilizing technology and systems for the purpose of collecting,
validating, and verifying information.

Develop, acquire, install, and utilize technology and systems for the
purpose of processing and maintaining 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.

Transmit, or otherwise disclose the information.

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 AIRS Facility Subsystem (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, and note the operating conditions under which
compliance was achieved.  Data and records maintained by the respondents
are tabulated and published for use in compliance and enforcement
programs.

Information contained in the reports is entered into the AFS which is
operated and maintained by EPA’s Office of Compliance.  AFS is EPA’s
database for the collection, maintenance, and retrieval of compliance
and annual emission inventory data for more than 100,000 industrial and
government-owned facilities.  EPA uses the AFS for tracking air
pollution compliance and enforcement by local and state regulatory
agencies, EPA regional offices and EPA headquarters.  EPA and its
delegated Authorities can edit, store, retrieve and analyze the data. 
The records required by this regulation must be retained by the owner or
operator for 

two years.

5(c)  Small Entity Flexibility

Currently the number of employees at a typical ammonium sulfate plant
exceeds the criterion for small business.  However, the impact on small
entities (i.e., small businesses) was taken into consideration during
the development of the regulation.  Due to technical considerations
involving the process operations and the types of control equipment
employed, the recordkeeping and reporting requirements are the same for
both small and large entities.  The Agency considers these requirements
the minimum needed to ensure compliance and, therefore, cannot reduce
them further for small entities.  To the extent that larger businesses
can use economies of scale to reduce their burden, the overall burden
will be reduced.

5(d)  Collection Schedule

The specific frequency for each information collection activity within
this request is shown in Table 1: Annual Industry Burden for NSPS for
Ammonium Sulfate Manufacturing Plants (40 CFR part 60, subpart PP).

6.  Estimating the Burden and Cost of the Collection

Table 1 documents the computation of individual burdens for the
recordkeeping and reporting requirements applicable to the industry for
the Subpart included in this ICR.  The individual burdens are expressed
under standardized headings believed to be consistent with the concept
of burdens under the Paperwork Reduction Act.  Where appropriate,
specific tasks and major assumptions have been identified.  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 is estimated to be 246
(Total Labor Hours from Table 1).  These hours are based on Agency
studies and background documents from the development of the regulation,
Agency knowledge and experience with the NSPS program, the previously
approved ICR, and any comments received.

6(b)  Estimating Respondent Costs

(i)  Estimating Labor Costs

 

This ICR uses a Technical Labor Rate of $64.13 per hour.  This rate is
from the United States Department of Labor, Bureau of Labor Statistics,
June 2003, “Table 10. Private industry, by occupational and industry
group.”  The rate is from column 1, “Total compensation.”  The
rate has been increased by 110% to account for the benefit packages
available to those employed by private industry.

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

The only costs to the regulated industry resulting from information
collection activities required by the subject standard are labor costs. 
There are no capital/startup or operation and maintenance costs.

(iii)  Capital/Startup vs. Operation and Maintenance (O&M) Costs

The only types of industry cost associated with the information
collection activity in the regulations are labor costs.  There are no
capital/startup or operation and maintenance costs.

The total capital/startup costs for this ICR are zero.  This is the
total of column D in the above table.  

The devices used to record operating parameters must be installed and
maintained by the respondents in order to efficiently operate the
processing plant.  Therefore, the total operation and maintenance (O&M)
costs for this ICR are zero.  This is the total of column G.  

The total respondent costs have been calculated as the addition of the
capital/startup costs, and the annual operation and maintenance costs. 
The average annual cost for capital/startup and operation and
maintenance cost to industry over the next three years of the ICR is
estimated to be zero.  

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 is
estimated to be $1,264 (rounded).  This cost is based on the average
hourly labor rate at a GS-12, Step 1, times a 1.6 benefits
multiplication factor to account for government overhead expenses for a
total of $39.49.  This rate is from the Office of Personnel Management
(OPM) “2003 General Schedule” which excludes locality rates of pay. 
Details upon which this estimate is based appear in 

Table 2: NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR 60,
subpart PP).

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

Based on our research for this ICR, approximately four existing sources
currently subject to the standard.  It is estimated that no additional
sources will become subject to the regulation in the next three years.

Number of respondents is calculated using the following table which
addresses the three years covered by this ICR.

The number of Total Annual Responses is 4.   The total annual labor
costs are $15,808 (rounded).  Details regarding these estimates may be
found in Table 1. Annual Respondent Burden and Cost, NSPS for Ammonium
Sulfate Manufacturing Plants (40 CFR part 60, subpart PP).

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

(O&M) 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 are attached in Tables 1 and 2.  The annual public reporting
and recordkeeping burden for this collection of information are
estimated to average 61.5 hours per response.

6(f)  Reasons for Change in Burden

There is no change in burden from the most recently approved ICR.  This
ICR renewal was approved under the “renew without change” option and
reflects no increase in the number of new or modified sources.

6(g)  Burden Statement

The annual public reporting and recordkeeping burden for this
collection of information are estimated to average 61.5 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.

Assumptions:

a. Assume a technical labor rate of $64.13 from the United States
Department of Commerce Bureau of Labor Statistics, March 2003, Table 2:
Employment Costs of Civilian 

Workers by Occupational and Industry Group. The rates are from column 1:
Total compensation. The wage rate obtained from the table has been
increased by 110% to 

account for the benefit packages available to those employed by private
industry.

	b. Assume that there will be no new sources (respondents) over the 3
years period of this ICR.

c. As specified in the general provisions each performance test shall
consist of three separate runs using the applicable test method. Sources
are required to use Method 9 

published in the 11 Edition of the Official Methods of Analysis of the
Association of Official Analytical Chemists dated 1970. As specified in
the general provisions, 

each performance test shall consist of three separate runs using the
applicable test method. Each run shall be conducted for the time and
under the conditions specific 

in the applicable rule. The particulate matter concentration, and
volumetric flow rate of the effluent gas shall be determined by Method 5
which requires a sampling time and 

	a sample volume for each run of at least 60 minutes and 1.50 dscm (53
dscf). 

d. Assume 20 percent of initial performance tests must be repeated due
to failure.

	e. Sources are required to maintain a daily record of operating
parameters. Assume records will be recorded 365 days per year.

Assumptions:

a.  Assume that there will be no new sources (respondents) over the 3
years period of this information collection request (ICR).

	b.  Assume EPA personnel attend all initial performance tests.

c.  Assume 20 percent of initial performance tests are repeated due to
failure.

	d.  There will be no travel expenses associated with this ICR since we
have assumed that no new sources will become subject to this rule over
the 3 year period of this ICR.

e.  The cost is based on the average hourly labor rate at a GS-12, Step
1, times a 1.6 benefits multiplication factor to account for government
overhead expenses for a total of $39.49.

 This rate is from the Office of Personnel Management (OPM) A2003
General Schedule@ which excludes locality rates of pay.
