NESHAP for Portland Cement (40 CFR Part 63, Subpart LLL) (Renewal)

1.  Identification of the Information Collection

1(a)  Title of the Information Collection

NESHAP for Portland Cement (40 CFR Part 63, Subpart LLL) (Renewal), 

EPA ICR Number 1801.08, OMB Control Number 2060-0416

1(b)  Short Characterization/Abstract

The National Emission Standards for Hazardous Air Pollutants (NESHAP)
for the regulations published at 40 CFR part 63, subpart LLL, were
proposed on March 24, 1998, promulgated on June 14, 1999, and
subsequently revised on December 20, 2006.  These regulations apply to
the following facilities: each new, existing or reconstructed kiln,
in-line kiln/raw mill and greenfield raw material dryer at these
facilities, except for kilns and in-line kiln/raw mills that burn
hazardous waste and are subject to 40 CFR 63, subpart EEE or that burn
municipal solid waste and are subject to 40 CFR part 60, subpart Cb or
Ea.  In addition, the rule applies to each new, existing or
reconstructed clinker cooler; raw mill; finish mill; raw material,
clinker or finished product storage bin; conveying system transfer
point; bagging system and bulk loading and unloading system at
facilities that are major sources; and to each existing, reconstructed
or new brownfield raw material dryer at facilities that are major
sources.  This information is being collected to assure compliance with
40 CFR part 63, subpart LLL.

Emission limits for mercury from new cement kilns were established under
the December 2006 final amendments. A mercury performance test is
required to demonstrate compliance with the emission limits for mercury.
The final amendments also established emission limits for total
hydrocarbons (THC) for new kilns and revise the emission limits for new
greenfield kilns.  To demonstrate compliance with the THC limits, owners
or operators of new kilns would be required to continuously monitor THC
emissions. To ensure proper combustion of organic HAP from existing
kilns, owners or operators of portland cement manufacturing plants must
implement good combustion practices (GCP) designed to minimize THC from
fuel combustion. Respondents are required to maintain additional records
to demonstrate compliance with THC limits. The 2006 final amendments
also required that records be kept of the amount of cement kiln dust
(CKD) that is removed from existing and new kiln systems and either
disposed of as solid waste or otherwise recycled for a beneficial use
outside of the kiln system. 

In addition to the new requirements established from the 2006
amendments, in general, all 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 the
NESHAP.

Any owner or operator subject to the provisions of this part 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 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 United States Environmental Protection
Agency (EPA) regional office.

Approximately 94 portland cement plants with 158 non-hazardous waste
cement kilns are currently subject to the regulation.  It is estimated
that 20 new kilns will be built over the next five years or 12
additional sources will become subject to the regulation over the next
three year ICR period.  All new kilns are estimated to be constructed at
existing portland cement plants, and it is estimated that two new kilns
will be installed at two existing plants, for a total of 4 new kilns per
year.  Since the records and reports are maintained at the plant-level,
the estimate for the number of respondents to this ICR is tracked at the
plant-level.  Although there are new kilns estimated at existing plants,
there are no new respondents estimated during this ICR.

The Office of Management and Budget (OMB) approved the currently active
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 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.  These
standards are applicable to new or existing sources of hazardous air
pollutants and shall require the maximum degree of emission 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, hazardous air pollutant (HAP) emissions
from portland cement manufacturing facilities cause or contribute to air
pollution that may reasonably be anticipated to endanger public health
or welfare.  Therefore, the NESHAP were promulgated for this source
category at 40 CFR part 63, subpart LLL.

2(b)  Practical Utility/Users of the Data

The control of emissions of HAPs from portland cement manufacturing
facilities requires not only the installation of properly designed
equipment, but also the operation and maintenance of that equipment. 
Emissions of HAPs from portland cement manufacturing facilities are the
result of operation of the affected facilities.  The subject standards
are achieved by the capture of particulate HAP emissions using fabric
filters or electrostatic precipitators control, temperature control for
the reduction of dioxins and furans (D/F), and feed selection for
reduction of other organic HAP.  

The recordkeeping and reporting requirements in the standard(s) ensure
compliance with the applicable regulations that were promulgated in
accordance with the Clean Air Act.  The collected information is also
used for targeting inspections and as evidence in legal proceedings.

Performance tests are required in order to determine an affected
facility’s initial capability to comply with the emission standards. 
Continuous emission monitors are used to ensure compliance with the
standards at all times.  During the performance test a record of the
operating parameters under which compliance was achieved may be recorded
and used to determine compliance in place of a continuous emission
monitor.

The notifications required in the standards 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 leaks are being detected and
repaired and the standards are being met.  The performance test may also
be observed.

The required semiannual reports are used to determine periods of excess
emissions, identify problems at the facility, verify
operation/maintenance procedures and for compliance determinations.

 

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

The recordkeeping and reporting requested is required under 40 CFR part
63, subpart LLL.

3(a)  Non-duplication

 

If the 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 regulation 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 on July 8, 2009 (74 FR 32580).  No
comments were received on the burden published in the Federal Register.

3(c)  Consultations

 The agency is basing the burden estimates of this ICR on estimates
prepared for the December 20, 2006 amendments. During those amendments,
the Agency consulted with industry experts and internal data sources to
project the number of affected facilities and industry growth over the
next three years.  Those included in those consultations included State
and local agencies, individual portland cement manufacturing plants,
industry trade associations, and environmental groups. We specifically
consulted with stakeholders on some of the ICR requirements of these
final amendments.  Participants in the development process for those
amendments included STAPPA/ALAPCO, the Portland Cement Association
(PCA), the American Portland Cement Alliance (APCA), the Small Company
MACT Coalition, the Sierra Club, and Earth Justice.  Several meetings
with industry representatives were held in the period leading to
proposal and the final amendments, and public comments received from
trade associations, cement companies, State and local regulatory
agencies, and environmental groups were considered in the development of
the current rule. Public comments received following proposal were
considered in developing the final amendments regarding monitoring,
recordkeeping, or reporting procedures.  

It is our policy to respond after a thorough review of comments received
since the last ICR renewal as well as those submitted in response to the
first Federal Register notice.  In this case, no comments were received.

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 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 proper operation
and maintenance of control equipment and the possibility of detecting
violations would be less likely.

3(e)  General Guidelines

These reporting or recordkeeping requirements do not violate any of the
regulations promulgated by OMB under 5 CFR Part 1320, section 1320.5.
However, most NESHAP standards and a few NSPS standards require records
to be kept more than three years.  In general, these standards require
the respondents to maintain all records, including reports and
notifications, for five years.  The five-year record retention
requirement is consistent with the permit program at 40 CFR part 70, and
the five-year statute of limitations on which the permit program is
based.

The retention of records for five years allows EPA to establish the
compliance history of the respondent for purposes of determining the
appropriate level of enforcement action.  Historically, EPA notes that
the most flagrant violations have extended beyond a five-year period. 
If records are retained for less than five years, EPA would be deterred
from pursuing the most flagrant violations due to the destruction of
records documenting noncompliance.

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

The reporting or recordkeeping requirements in the standard do not
include sensitive questions.

4.  The Respondents and the Information Requested

4(a)  Respondents/NAICS Codes

The respondents to the recordkeeping and reporting requirements are
portland cement manufacturing facilities.  The United States Standard
Industrial Classification (SIC) code for the respondents affected by the
standards is 3241 which corresponds to the North American Industry
Classification System (NAICS) 32731 for portland cement manufacturing
facilities.

Train personnel to be able to respond to a collection of information.

Transmit, or otherwise disclose the information.

Electronic Reporting

At the present, many respondents to CAA standards use monitoring
equipment that automatically records parameter data.  Although personnel
at the affected facility must evaluate the data, this internal
automation has significantly reduced the burden associated with
monitoring and recordkeeping at the 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.

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

5(a)  Agency Activities

EPA conducts one or more of 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 (Aerometric Information
Retrieval System) Facility Subsystem (AFS) database.

5(b)  Collection Methodology and Management

The required data and reports can be evaluated on-site by conducting a
partial compliance evaluation, full compliance evaluation or inspection,
or through an off-site review of compliance monitoring records and
reports.  Evaluation reports and inspection results are maintained by
the Agency or delegated authority.

The results of these evaluations are entered into the Air Facility
Subsystem (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 data for approximately 125,000 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 delegated
authorities can retrieve and analyze the data.

The records required by this regulation must be retained by the
owner/operator for five years.

5(c)  Small Entity Flexibility

A majority of the respondents are large entities (i.e., large
businesses).  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.  The PCA study “U.S. and Canadian Portland Cement Industry: 
Plant Information Summary,” indicates there are 35 companies with
affected Portland cement facilities.  Of these, six companies (or 17
percent) are considered small entities.  The Agency assumes that 17
percent of the 94 facilities affected by this ICR, or 16 facilities, are
small entities.

5(d)  Collection Schedule

The specific frequency for each information collection activity within
this request is shown below in Table 1.

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. 
The individual burdens are expressed under standardized headings
believed to be consistent with the concept of burden 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 28,242
hours (Total Labor Hours from Table 1).  The recordkeeping hours shown
below in Table 1 are 25,545 hours.  The reporting requirement hours
shown below in Table 1 are 2,697.  These hours are based on Agency
studies and background documents from the development of the regulation,
Agency knowledge and experience with the NESHAP program, the previously
approved ICR, and any comments received.

6(b)  Estimating Respondent Costs

(i)  Estimating Labor Costs 

This ICR uses the following labor rates: 

Managerial	$114.77 ($54.65 + 110%)   

Technical	$97.59 ($46.47 + 110%)

Clerical	$48.26 ($22.98 + 110%)

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

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

The types of industry costs associated with the information collection
activity in the regulations are for labor and continuous emission
monitoring (CEM).  Since the 2006 amendments required all new kilns
constructed on or after December 2, 2005, to install THC monitors, it is
also assumed that a THC CEM will be installed on each new kiln. The
capital cost and the O&M cost of the THC monitor were estimated using an
updated Version 3 of EPA’s Continuous Emission Monitoring System Cost
Model.  The capital/startup costs are one-time costs when a facility
becomes subject to the regulation.  The annual operation and maintenance
costs are the ongoing costs to maintain the monitor and other costs such
as photocopying and postage.

The total capital/startup costs for this ICR are $1,439,200.  This is
the total of column D in the above table. 

The total operation and maintenance (O&M) costs for this ICR are
$880,092.  This is the total of column G. 

The average annual cost for capital/startup and O&M costs to the
industry over the next three years of the ICR is estimated to be
$2,319,292.  This is the average annual cost for the 3-year ICR period
from column G above which includes annual O&M costs and annualized
capital costs as discussed below.  These are recordkeeping costs.

(iv) Annualizing Capital Costs 

The capital cost associated for a THC monitor and CEM was annualized
assuming a 7 percent interest rate and 10-year life (i.e., capital
recovery factor [CRF] of 0.1424).  The total annualized capital costs
total $204,910.

6(c)  Estimating Agency Burden and Costs

The only costs to the Agency are those 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 and the publication and distribution of collected
information.

The average annual Agency cost during the three years of the ICR is
estimated to be $243,774 and is shown below in Table 2. 

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% to account for the benefit packages available to
government employees.  Details upon which this estimate is based appear
below in Table 2: Average Annual EPA Burden – NESHAP for Portland
Cement (40 CFR Part 63, Subpart LLL) (Renewal).

Because all of the new kilns expected to be constructed are located at
plants that also have existing sources, two of the 94 plants
(respondents) can be classified as both a new and existing source. To
avoid double-counting respondents, column D is subtracted.  The average

6(e)  Bottom Line Burden Hours Burden Hours and Cost Tables

The detailed bottom line burden hours and cost calculations for the
respondents and the Agency are shown in Tables 1 and 2, respectively,
and summarized below.  

(i) Respondent Tally

The total annual labor hours are 28,242.  Details regarding these
estimates may be found below in Table 1:  Annual Respondent Burden and
Cost - NESHAP for Portland Cement (40 CFR Part 63, Subpart LLL)
(Renewal).  Furthermore, the annual public reporting and recordkeeping
burden for this collection of information is estimated to average 69.56
hours per response.

The average annualized capital/startup and annual O&M costs to the
regulated entity are $2,319,292.  The cost calculations are detailed in
Section 6(b)(iii), Capital/Startup vs. Operation and Maintenance (O&M)
Costs.

(ii) The Agency Tally

	The average annual Agency burden and cost over next three years is
estimated to be 5,437 labor hours at a cost of $243,774.  See below
Table 2:  Annual Agency Burden and Cost - NESHAP for Portland Cement (40
CFR Part 63, Subpart LLL) (Renewal).

	6(f)  Reasons for Change in Burden

The increase in burden hours and dollars from the most recently approved
ICR renewal (EPA ICR number 1801.07) is due to a 2006 program change in
the regulation requiring additional performance testing, monitoring,
recordkeeping, and reporting requirements. These amendments would affect
any new, modified, or reconstructed sources after December 2, 2005.  

There was a decrease in number of responses currently identified in the
OMB Inventory of Approved Burdens.  This decrease is due to the
correction of transpose error in the currently approved burden estimates
in ICRAS. Further, the number of responses also decreased due to a
decrease in the number of estimated portland cement plants affected by
ICR since the last renewal. 

The increase in capital/start-up and O&M costs is also due to a 2006
program change in the regulation requiring new monitoring equipment. The
THC monitors are a new requirement for new sources since the last ICR
renewal.  Further, the change in labor costs for industry and EPA is due
to the use of more current labor rates. 

6(g)  Burden Statement

The annual public reporting and recordkeeping burden for this
collection of information is estimated to average 69.56 hours per
response.  Burden means the total time, effort, or financial resources
expended by persons to generate, maintain, retain, disclose, or provide
information to or for a Federal agency.  This includes the time needed
to review instructions; to develop, acquire, install, and utilize
technology and systems for the purposes of collecting, validating and
