**SUPPORTING STATEMENT ENVIRONMENTAL PROTECTION AGENCY**  **NSPS for**  **Ammonium Sulfate Manufacturing Plants (40 CFR**  **Part 60, Subpart PP)**  **(Renewal) 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), EPA I CR Number 1066.07, OMB Control Number 2060

- 0032

. **1(b) Short Characterization/Abstract** The New Source Performance Standards (NSPS) for Ammonium Sulfate Manufacturing Plants were proposed on February 4, 1980 , promulgated on November 12, 1980 , and amended on October 17, 2000. These regulations appl y to ammonium sulfate dryers located at both existing and new ammonium sulfate manufacturing plant s in the cap rolactam by

- product, sy nthetic, and coke oven b y - products sectors of the ammonium sulfate manufacturing industry

. New facilities include those that commenced construction, modification , or reconstruction after the date of proposal. This information is be ing collected to assure compliance with 40 CFR part 60, subpart PP

. In general, all NSPS standards require initial notifications, performance 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 an y startup, shutdown, or malfunction in the operation of an affected facility , or any period during which the monitoring s ys tem 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. Over the next three ye ars, an average of two respondents will be subject to the standard , and due to the static nature of the industry , it is estimated that no additional respondents per ye ar will become subject to the standard. The industry is dominated by

facilities that have been operating 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 Office of Management and Budget ( OMB ) approved the currentl y active I CR without any

“Terms of Clearance.” The burden to the “Affected Public” may be found below in Table 1: Annual Respondent2

Burden and Cost

– NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR Part 60, Subpart PP) (Renewal). T he “burden ” to the Federal g overnment is attributed entirel y to work performed b y either F ederal employees or government contractors and may be found below in Table 2: Average Annual EPA Burden and Cost

– NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR Part 60, Subpart PP) (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 (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 an y no n - air quality health and environmental impact and energy requirements) the Administrator 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 an d 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 interv als, 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 cert ifications 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 emissions from the ammonium sulfate manufacturing industry

cause or contribut e 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

.3

**2(b) Practical Utility/Users of the Data** The recordkeeping and reporting requirements in the standard s ensure compliance with the applicable regulations which where promulgated in accordance with the Clean Air Act. The collected information is also used for targeting inspections and as evidence in legal proceedings.
P erformance tests are required in order to determine an affected facility ’ s initial capability to comply

with the emission standard s . Continuous emission monitors are used to ensure compliance with the standard at all times. During the performance test , a r ecord 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 auth ority 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 s 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 requested recordkeeping and reporting are required under 40 CFR part 60, subpart PP

. **3(a) Non**
**- duplication**  If the subject standards have not been delegated, the info rmation 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 co py 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 anno uncement of a public comment period for the renewal of this I CR was published in the Federal Register ( 77 FR 63813 ) on October 17, 2012

. No comments were received on the burden published in the Federal Register

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

experts have been consulted, and the Agency ’s internal data4

sources and projections of industry growth over the next three y ears have been considered. The primary

source of information as reported by industry , in compliance with the recordkeeping and reporting provisions in the standard, is the Online Tracking Information Sy stem (OTIS) which is operated and maintained by EPA's Office of Compliance. OTIS is EPA’s database for the collection, maintenance, and retrieval of all compli ance 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 sta ndard as it was being developed and the standard has been previously

reviewed to determine the minimum information needed for compliance purposes. In developing this I CR, we contacted : 1) the Am erican Chemical Society ( ACS ) , at ( 800 ) 848

- 6538 ; and 2) the American Agricultural Economics Association , at ( 414 ) 918

- 3190

. 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 likel y. **3(e) General Guidelines**
T hese reporting or recordkeeping requirements do not violate any of the regulations promulgated by OMB under 5 CFR part 1320, section 1320.5. These standards require the respondents 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

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

- ye ar statute of lim itations on which the permit program is based. The retention of records for five ye ars allows EPA to establish the compliance history of a source, an y pattern of non

- compliance and to determine the appropriate level of enforcement action. EPA has foun d 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. **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 2,5

subpart B

- Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR 36902, September 1, 197 6; amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979). **3(g) Sensitive Questions**
T he 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 ammonium sulfate manufacturing facilities

. The United States Standard Industrial Classification ( SI C ) code for the respondents affected b y the standards is SI C 2873 which corresponds to the North American Industry Classification Sy stem (NAICS ) code 325311 for Nitrogenous Fertilizer Manufacturing

. **4(b) Information Requested (i) Data Items** 
In this ICR , all the data that is recorded or reported is required b y the NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR P art 60, S ubpart PP). A source must make the following reports:

**Notification s**  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)
**Reports** Semiannual report 60.7(c) A source must keep the following records:
**Recordkeeping** Initial performance test results 60.8(a) Startup, shutdowns, and malfunctions 60.8(c)6 **Recordkeeping** Control device operating parameters (continuous) 60.423 Records should be retained for two ye ars 60.7(f) Electronic Reporting Some of the r espondents 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 recordke eping at a plant site. Also, regulatory

agencies in cooperation with the 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 th at approximately 10 percent of the respon dents use electronic reporting.

**(ii) Respondent Activities**

**Respondent Activities** Read instructions. Install, calibrate, maintain, and operate a flow monitoring device to determine the mass

- flow of ammonium sulfate feed material to the process Install, calibrate, maintain, and operate a CMS for particulate matter (PM) and a CMS for pressure drop across the emission control sy stem Perform initial performance test, Reference Method 9 and 5 test, 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 type of monitoring equipment has significantly reduced the burden associated with monitoring and recordkeeping.
**5. T he 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 infor mation.
**Agency 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 compl y with the emission standard. Data and records maintained by the respondents are tabulated and published for use in complianc e 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 m aintained 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

- owned facilities. EPA uses the OTI S for tracking air pollution complianc e and enforcement b y local and state regulatory agencies, EPA regional offices and EPA headquarters. The EPA and its delegated Authorities can edit, store, retrieve and anal yz e the data.8

The records required b y this regulation must be retained by the own er/operator for two ye ars. **5(c) Small Entity Flexibility** There are no small entities (i.e., small businesses) affected b y this regulation. However, the impact on small entities (i.e., small businesses) was taken into consideration during the develo pment 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 th ese 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 Ammonium Sulfate Manufacturing Plants (40 CFR Part 60, Subpart PP) (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. 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 record

keeping and reporting requirement s is estimated to be 28 4 ( Total Labor Hours from Table 1 below ). T hese hours are based on Agency studies and background documents from the development of the regulation, Agency knowled ge and experience with the NSPS program, the previously

- approved ICR, and any comments received. **6(b) Estimating Respondent Costs (i) Estimating Labor Costs**  This I CR uses the following labor rates:9 Managerial $ 121.44 ($ 57.83 + 110%) Technical $ 100.23 ($ 47.73 + 110%) Clerical $ 50.51 ($ 24.05 + 110%) These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2012 , “ 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 only costs to the regulated industry resulting from information collection activities required b y the subject standard are labor costs. There are no capital/startup or operation and maintenance costs

.

**(iii) Capital/Startup vs. Operation and Maintena nce (O&M) Costs**  The only t ype of industry costs associated with the information collection activity in the regulations is labor costs. There are no capital/startup or operation and maintenance costs. **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 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 $ 1,658

. 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

- 6, Step 3, $ 15. 63 + 60% ) These rates are from the Office of Personnel Management (OPM) , 20 1 2 General Schedule , which excludes locality , rates of pay

. 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 Ammonium Su lfate Manufacturing Plants (40 CFR Part 60, Subpart PP) (Renewal)

. **6(d) Estimating the Respondent Universe and Total Burden and Costs** Based on our research for this I CR, approximately two existing respondents will be10

subject to the standards per year over the next three years
. Itis also estimated that n o additional respondents will become subject to the standards over the next three ye ars . The overall average number of respondents, as shown in the table below is two per year. The number of respon dents is calculated using the following table that addresses the three ye ars covered b y this ICR.
**Number of Respondents**

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

– NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR Part 60, Subpart PP) (Renewal)

.11

**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. **(i) Respondent Tally** The total annual labor hours are 28 4 hours at a cost of $27,449

. Details regarding these estimates may

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

– NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR Part 60, Subpart PP) (Renewal)

. Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 71 hours per response

. Both the total annual capital/startup and O&M costs to the regulated entity are zero. 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 y ears is estimated to be 37 labor hours at a cost of $ 1,658 . See below Table 2: Average Annual EPA Burden and Cost

– NSPS for Ammonium Sulfate Manufacturing Plants (40 CFR Part 60, Subpart PP) (Renewal)

. **6(f) Reasons for Change in Burden** There is an increase in burden hours for both the respondents and the Agency due to a correction in the calculation methodology . The previous I CR assumed the hours per occurrence for each burden activity

included technical, managerial, and clerical hours. This I CR assumes these hours per occurrence are for technical hours only , and calculates additional managerial and clerical hours as 5 and 10 percent of technical hour s. Th ere is also an increase in the respondent burden costs due to a change in labor rates. This ICR uses updated labor rates from the Bureau of Labor Statistics to calculate respondent burden costs. Additionally , there is a decrease in burden costs fo r the Agency from the most

- recentl y approved ICR due to a correction in labor rates. The previous ICR incorrectly used civilian rates to calculate Agency

burden. This I CR uses rates from OPM, which results in an overall reduction in the Agency

cost estim ates. **6(g) Burden Statement** The annual public reporting and recordkeeping burden for this collection of information is estimated to average 71 hours per response. 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; devel op,12

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 pr eviously

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 regulations are listed at 40 CFR part 9 and 48 CFR chapter 15.

a. We have assumed that there are approximately 2 respondents subject to the rule, with no new sources expected over the next three

- years of this ICR. b. This ICR uses the following labor rates: Technical $100.23 ($47.73 + 110%); Managerial $121.44 ($57.83+ 110%); and Clerical $50.51 ($24.05 + 110%). These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2012, “Table 2. Civilian Workers, by occupation al 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 t o those employed by private industry. This ICR assumes that Managerial hours are 5 percent of Technical hours, and Clerical hours are 10 percent of Technical hours.
c. We assume that there will be no new sources over the 3

- year period of this ICR. d. As specified in the general provisions each performance test shall consist of three separate run s using the applicable test method. Sources are required to use Method 9 published in the 11 th edition of the Official Methods of analysis of the Association of Official analytical Chemists dates 1970 . Each run shall be conducted for the time and under the conditions specified 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).
e. We assume that 20 percent of initial performance tests must be repeated due to failure. f. We have assumed that it will take each respondent 16 hours twice per year to complete the semiannual reports. g. Sources are required to maintain a daily record of operating parameters. We assume records will be recorded 365 days per year.15
