**SUPPORTING STATEMENT ENVIRONMENTAL PROTECTION AGENCY**  **NSPS for Phosphate Rock Plants (40 CFR**  **Part 6 0, Subpart NN) (Renewal)**  **1. Identification of the Information Collection 1(a) Title of the Information Collection**  NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal), EPA I CR Number 10 78.10 , OMB Control Number 2060

- 0111

. **1(b) Short Characterization/Abstract** The New Source Performance Standards (NSPS) for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) were : 1) proposed on September 21, 1979 ; 2) promulgated on April 16, 1982 ; and 3) amended on February 14, 1989, May

17, 1989, February

12, 1999, and October 17, 2000

. These regulations apply to the following new facilities at phosphate rock pl ants with capacities greater than 4 tons per hour: dryers, calciners, grinders, and ground rock handling and storage facilities, except those facilities producing or preparing phosphate rock solely for consumption in elemental phosphorus production. New f acilities include those that commenced construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR part 60, subpart NN

. In general, all NSPS standards require initial notifications, perf ormance tests, and periodic reports by

the owners/operators of the affected facilities. They 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 sy stem is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NSPS. Any owner/operator subject to the provisions of this part 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. 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 directl y to the U

. S

. Environmental Protection Agency (EPA) regional office. Based on our consultations with industry representatives, there is an average of one affected facilities at each plant site and that each plant site has only one respondent (i.e., the owner/operator of the plant site). Over the next three ye ars, an average of 14 respondents per ye ar will be subject to the standard s , and one additional respondent will become subject to the standard s in the next three ye ars
. The Office of Management and Budget ( OMB) approved the currentl y active I CR without any

“Terms of Clearance.”2

There are approximately

1 4 phosphate rock plants in the United States, which are all publicly

- owned and operated by the Phosphate Rock industry . None of the 14 plants in the United States are owned by either state , or local, or tribal entities , or by the Federal government. They are all owned and operated sol el y b y privately

- owned , for

- profit businesses. The “burden ” to the “Affected Public” may be found below in Table 1: Annual Respondent Burden and Cost

– NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal) . The Federal Government “burden ” is attributed entirel y to work performed b y either F ederal emplo ye es or government contractors and may be found below in Table 2: Average Annual EPA Burden and Cost

– NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal)

. **2. Need for an d 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 sy stem 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 Administrat or determines has been adequatel y 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 addition, section 114(a) states that the Administrator may require any owner/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 moni toring 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 reasonabl y require. In the Administrator's judgment, particulate matter (PM) emissions from phosphate rock plants cause or contribute to air pollution that may reasonabl y be anticipated to endanger public health or welfare. There fore, the NSPS were promulgated for this source category at 40 CFR3

part 60, subpart NN

. **2(b) Practical Utility/Users of the Data** The recordkeeping and reporting requirements in the standard ensure compliance with the applicable regulations which where p romulgated 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 comp ly

with the emission standard s
. Continuous e mission monitors are used to ensure compliance with the standard s 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 standard s 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 properl y installed and operated , leaks are being detected and repaired , and the standard is 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 requested recordkeepin g and reporting are required under 40 CFR part 60, subpart NN

. **3(a) Non**
**- duplication**  If the subject standards have not been delegated, the information is sent directl y to the appropriate EPA regional office. Otherwise, the information is sent directl y 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 cop y 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, duplication does not exist. **3(b) Public Notice Required Prior to ICR Submission to OMB** An announcement of a public comment period for the renewal of this I CR was published in the Federal Register ( 78 FR 3 3409 ) on June 4, 2013. No comments were received on the burden published in the Federal Register

.4

**3(c) Consultations** The Agency ’s industry

experts have been consulted, and the Agency ’s internal data sources and projections of industry growth over the next three years have been considered. The primary source of information as reported b y industry , in compliance with the recordkeeping and reporting provisions in the standard, is the Online Tracking Information System (OTI S) which is operated and maintained by EPA's Office of Compliance. OTIS is EPA’s database for the collection, maintenance, and retrieval of all complianc e data. The growth rate for the industry is based on our consultations with the Agency ’s internal industry experts. Industry trade associations and other interested parties were provided an opportunity to comment on the burden associated with the standard s as they were being developed and the standard s have been reviewed previously to determine the minimum information needed for compliance purposes. Indeveloping this ICR, we contacted : 1) the Association of Fertilizer and Phosphate Chemists , at (813) 5 45

- 3711 ; and 2) the Fertilizer Institute , at (202) 962

- 0490

. 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 frequentl y, 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 b y OMB under 5 CFR part 1320, section 1320.5. These standards require the respondents to maintain all records, including rep orts and notifications for at least five years. This is consistent with the General Provisions as applied to the standards. EPA believes that the five

- ye ar records retention requirement is consistent with the Part 70 permit program and the five

- ye ar 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 a source, any pattern of non

- compliance and to determine the appropriate level of enforcement action. EPA h as found that the most flagrant violators have violations extending beyond five ye ars. In addition, EPA would be prevented from pursuing the violators due to the destruction or nonexistence of essential records.5

**3(f) Confidentiality** Any information su

bmitted 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/SIC Codes** The respondents to the recordkeeping and reporting requirements are phosphate rock plants . The United States Standard Industrial Classification ( SI C ) code for the respondents affected b y the standards is SI C 1475 , which corresponds to the North American Industry Classification System (NAI CS ) code 2 12392 for Phosphate Rock Mining

. **4(b) Information Requested (i) Data Items** 
In this ICR , all the data that is recorded or reported is required by the NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN)

. . A source must make the following reports:

**Notification s**  **/Reports** Notification of construction or reconstruction 60.7(a)(1) Notification of actual startup 60.7(a)(3) Notification of phys ical or operational change which may increase the emission rate 60.7(a)(4) Notification of demonstration of continuous monitoring s ys tem 60.7(a)(5) Notification of initial performance test 60.8(d) Report on initial performance test 60.8(a) Semiannual report on excess emissions 60.7(c)6

A source must keep the following records: **Recordkeeping** Maintain records of startups, shutdowns, malfunctions, periods where the continuous monitoring s ys tem is inoperative 60.7(b) Maintain all records for two years 60.7(f) Electronic Reporting 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 th e respondents continue to create reporting sy stems to transmit data electronically . However, electronic reporting s ys tems are still not widely used. At this time, it is estimated that approximately 10 percent of the respon dents use electronic reporting.

**(ii) Respondent Activities**

**Respondent Activities** Read instructions. Install, calibrate, maintain, and operate CMS for opacity , or for pressure drop and liquid supply pressure for wet scrubber. Perform initial performance test, Reference Method 5 and 9 test s , 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 sy stems for the purpose of collecting, validating, and verifying information. Develop, acquire, install, and utilize technology and sy stems for the purpose of processing and maintaining information. Develop, acquire, install, and utilize technology and sy stems for the purpose of disclosing and providing information.7 **Respondent Activities** Train personnel to be able to respond to a collection of information. Transmit, or otherwise disclose the information. Currently sources are using monitoring and reporting equipment that provide parameter data in an automated way ( e.g., continuous parameter monitoring s ys tem) . Although personnel at the source still need to evaluate the data, this ty pe of monitoring equipment has significantl y reduced the burden associated with monitoring and recordkeeping. **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, analy sis, storage, and distribution of the required information. **Agenc y Activities**  Review notifications and reports, including performance test reports, and excess emissions reports, required to be submitted by industry

. Audit facility

records. Input, anal yz e, and maintain data in the Online Tracking Information Sy stem (OTI S). **5(b) Collection Methodology and Management** Following notification of startup, the reviewing authority could inspect the source to determine whether the pollution control devices are p roperl y installed and operated. Performance test reports are used b y the Agency to discern a source ’ s initial capability to comp ly with the emission standard, and note the operating conditions under which compliance was achieved. Data and records maintai ned 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.
In formation contained in the reports is entered into OTI S which is operated and maintained by

EPA's Office of Compliance. OT IS is EPA ’ s database for the collection, maintenance, and retrieval of compliance data for approximately 125,000 industrial and government

- owne d facilities. EPA uses the OTI S for tracking air pollution compliance and enforcement b y local and state regulatory agencies, EPA regional offices and EPA headquarters.8

EPA and its delegated Authorities can edit, store, retrieve and analyze the data.
The records required b y this regulation must be retained by the owner/operator for two ye ars. **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 ty pes of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities. The Agency considers these to be the minimum requirements 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 below Table 1: Annual Respondent Burden and Cost

– NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal )

. **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 I CR. The individual burdens are expressed under standardized headings believed to be consistent with the concept of burden under the Paperwork Reduction Act. Wherever 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 requirement s is estimated to be 1,724 hours ( Total Labor Hours from Table 1 below). 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 IC R, and any

comments received.9

**6(b) Estimating Respondent Costs (i) Estimating Labor Costs**  This I CR uses the following labor rates: Managerial $ 123.04 ($5 8

. 59 + 110%) Technical $ 10 1

. 2 2 ($4 8

. 2 0 + 110%) Clerical $ 51

. 18 ($2 4

. 37 + 110%) These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2013 , “ Table 2. Civilian Workers, by occupational and industry group. ” The rates are from column 1, “ Total compensation. ” The rates have been increased b y 110 percent to account for the benefit packages available to those employed by private industry

. **(ii) Estimating Capital/Startup and Operation and Maintenance Costs**  The ty pe of industry

costs associated with the information collection activities in the subject standard are both labor costs which are addressed elsewhere in this ICR and the costs associated with continuous monitoring. Th e 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.

. This is the total of column G. The average annual cost for capital/startup and operation and maintenance costs to industry

over the next three years of the IC R is estimated to be $ 132,582

. These are recordkeeping costs

.10

**6(c) Estimating Agency Burden and Cost** The only costs to the Agency

are those costs associated with anal ys is of the reported information. EPA's overall compliance and enforcement program includes activities such as the examination of records maint ained 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 $ 6,707

. This cost is based on the average hourl y labor rate as follows: Managerial $ 6 2.27 (GS

- 13, Step 5, $ 3 8. 92 + 60% ) Technical $ 4 6

. 21 (GS

- 12, Step 1, $ 28. 88 + 60% ) Clerical $2 5.01 (GS

. The rates have been increased b y 60 percent 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 and Cost

– NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal). **6(d) Estimating the Respondent Universe and Total Burden and Costs**  Based on our research for this I CR, on average over the next three ye ars, approximately 14 existing respondents will be subject to the standard. It is estimated that one additional respondent over the next three years will become subject. The overall average number of respondents, as shown in the table below, is 14.33 per year. The number of respondents is calculated using the following table that addresses the three ye ars covered b y this I CR. **Number of Respondents**

. The total annual labor costs are $ 168,674

. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost

– NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal)

. **6(e) Bottom Line 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, respectivel y, and summarized below.12 **(i) Respondent Tally** The total annual labor hours are 1,724 hours at a cost of $168,674

. Details regarding these estimates may

be found below in Table 1 : Annual Respondent Burden and Cost

– NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal)

. Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 56 hours per response

. The total annual capital/startup and O&M costs to the regulated entity are $132,582

. 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 149 labor hours at a cost of $6,707 . See below Table 2: Average Annual EPA Burden and Cost

– NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal)

. **6(f) Reasons for Change in Burden** The increase in burden from the most recentl y approved ICR is due to an increase in the number of new or modified sources and an increase in labor costs

. This I CR uses updated labor rates from the Bureau of Labor Statistics to calculate burden costs. **6(g) Burden Statement** The annual public reporting and recordkeeping burden for this collection of information is estimated to average 56 hours per r esponse. Burden means the total time, effort, or financial resources expended b y 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 s ys tems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing way s to compl y with any previously

app licable 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 regulations are listed at 40 CFR part 9 and 48 CFR chapter 15. To comment on the Agenc y'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 I CR under13

**Assu mptions:** 
a We have assumed that the average number of respondents that will be subject to the rule will be 14.33. It is estimated that one new source will become subject to the rule over the three

- year period of this ICR. b This ICR uses the following labor rates: $123.04 per hour for Executive, Administrative, and Managerial labor; $101.22 per ho ur for Technical labor, and $ 51.18 per hour for Clerical labor. These rates are from the United States Department of Labor, Bur eau of Labor Statistics, March 2013 , “Table 2. Civilian Workers, by Occupational and Industry group.” The rates are from column 1, “Total Compensation.” The rates have been increa sed by 110 percent to account for the benefit packages available to those e mp loyed by private industry.
c We have assumed that 20 percent of initial performance test will be repeated due to failure. d We have assumed that no facility will be engaged in physical or operational changes.
e We have assumed that it will take each r espondent 2 hours each to w rite CMS notification report. f We have assumed that each respondent will take 8 hours, two times per year, to w rite semiannual report on excess emissions. g We have assumed that each respondent will take 15 minutes per day to record operating parameters information.16

**Assu mptions:** 
a We have assumed that the average number of respondents that will be subject to the rule will be 14.33. It is estimated that one new source will become subject to the rule over the three

- year period of this ICR. b The cost is based on the following labor rate which incorporates a 1.6 benefits multiplication factor to account for governme nt overhead expenses. Managerial rates of $62.27 (GS

- 13, Step 5, $38.92 x 1.6), Technical rate of $46.21 (GS

- 12, Step 1, $28.88 x 1.6), and Clerical rate of $25.01 (GS

- 6, Step 3, $15.63 x 1.6). These rates are from the Office of Personnel Management (OPM), 2013 General Schedule, which excludes locality rates of pay.
