**SUPPORTING STATEMENT ENVIRONMENTAL PROTECTION AGENCY**  **NSPS for**  **Ammonium Sulfate Manufacturing Plants (40 CFR Part 6**  **0 , 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 6 0 , Subpart PP ) (Renewal), EPA I CR Number 1066.08 , OMB Control Number 2060

- 0032

. **1(b) Short Characterization/Abstract**  The New Source Performance Standards (NSPS) for Ammonium Sulfate Manufacturing Plant s (40 CFR Part 60, Subpart PP) were proposed on February 4, 1980, promulgated on November 12, 1980, and amended on October 17, 2000

. These regulations apply to ammonium sulfate dryers located at both existing and new ammonium sulfate manufacturing plants in the caprolactam b y-product, sy nthetic, and coke oven by

- 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 being collected to assure compliance with 40 CFR Part 60, Subpart PP

. In general, all NSPS standards require initial notification report s, 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 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 es sential in determining compliance, and are required of all affected facilities subject to NSPS. Any owner/operator subject to the provisions of this part shall retain a file containing these notifications, reports, and records for at least two years follo wing the date of these document s. 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 U

. S

. Environmental Protection Agency (EPA) regional office. The “burden ” to the “Affected Public” 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)

. The Federal Government ’s “burden” is attributed entirel y to work performed b y either F ederal employees or government contractors and can 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). Over the next three ye ars, an average of two respondents will be subject to the se standard s , and due to the static nature of the industry , it is estimated that no additional respondents per ye ar will become subject to the se same standard s . The industry is dominated by2

facilities that h ave been operating prior to the proposed date of the rule (February 4, 1980), and there has been either a long

- term static or declining market for the product both domestically and globall y. The Office of Management and Budget ( OMB ) approved the currentl y active I CR 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 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 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 reasonabl y require. In the Administrator's judgment, particulate matter emissions from the ammonium sulfate manufacturing industry cause or contribute to air pollution that may reasonably

be anticipated to endanger public health or w elfare. Therefore, the NSPS were promulgated for this source category at 40 CFR Part 60, Subpart PP

. **2(b) Practical Utility/Users of the Data** 3

The recordkeeping and reporting requirements in the se standard s ensure compliance with the applicable regulation s which 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 standard s . Continuous emission 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 record ed and used to determine compliance in place of a continuous emission monitor. The notifications required in the se 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 reque sted recordkeeping an d reporting are required under 40 CFR Part 60, Subpart PP

. **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 b y 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 I CR was published in the Federal Register ( 80 FR 32116 ) on June 5, 2015

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

.
**3(c) Consultations** 4

The Agency

has consulted industry

experts and internal data sources to project the number of affected facilities and industry growth over the next three ye ars. The primary source of information as reported by industry , in compliance with the recordkeeping and reporting provisions in the standard, is the Integrated Compliance Information Sy stem (I CI S). I CI S is EPA’s database for the collection, maintenance, and retrieval of compliance data for industrial and government

- owned facilities. The growth rate for the industry is based on our consultations with the Agency ’s internal industry experts. Industry trade association and other interested parties were provided an opportunity to comment on the burden associated with the standard as it was being developed and the standard has been previously

reviewed to determine the minimum information needed for compliance purposes. In developing this I CR, we contacted The Fertilizer Institute , (TFI) , at ( 202) 962

- 0490 ; and the American Chemical Society (ACS) , at (800) 227

- 5558

. It is our policy

to respond after a thorough review of comments received since the last ICR renewal as well as those s ubmitted 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 b y these standards wa s 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 b y OMB under 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 fo rth 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) S**  **ensitive Questions** The reporting or recordkeeping requirements in the standard do not include sensitive5

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 System (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 Part 60, Subpart 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) Control device operating parameters (continuous) 60.423 Records should be retained for two ye ars 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, internal6

automation has significantly reduced the burden associated with monitoring and recordkeeping at a plant site. **(ii) Respondent Activities**  **Respondent Activities** Familiarization with the regulatory requirements. 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 CMS for particulate matter (PM) and a CMS for pressure drop across the emissi on control system

. Perform initial performance test, Reference Method s 9 and 5 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. 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** Review notifications and reports, including performance test reports, and excess emissions7 **Agency Activities** reports, required to be submitted by industry

. Audit facility

records. Input, anal yz e, and maintain data in the Enforcement and Compliance History Online (ECHO) and I CI 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 properl y in stalled and operated. Performance test reports are used b y the Agency to discern a source ’ s initial capability to comply

with the emission standard. Data and records maintained by the respondents are tabulated and published for use in compliance and enforc ement 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 reported b y state and local governments in the IC IS Air database, which is operated and maintained by EPA's Office of Compliance. IC IS is EPA ’ s database for the collection, maintenance, and retrieval of compliance data for industrial and government

- owned facilities. EPA uses IC IS for tracking air pollution compliance and enforcement b y 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 b y this regulation must be retained by the owner/operator for two ye ars. **5(c) Sm**  **all 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 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 redu ce 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 below in Table 1: Annual Respondent Burden and Cost

– NSPS for Ammonium Sulfate8

M anufacturing 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 identif ied. 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 Responden**  **t Burden** The average annual burden to industry over the next three years from these recordkeeping and reporting requirement s is estimated to be 286 hours ( 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 I CR uses the following labor rates: Managerial $1 2 9

. 93 ($ 61.87 + 110%) Technical $ 10 3

. 97 ($4 9

. 51 + 110%) Clerical $ 5 1

. 79 ($2 4

. 66 + 110%) These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2014 , “ 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 Maintenance (O&M) Costs**  The only type of industry costs associated with the information collection activity in the regulations are labor costs. There are no capital/startup or operation and maintenance costs.9

**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 such activities as the examination of records maint aine d 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 $ 1,670

. This cost is based on the average hourl y labor rate as follows:

Managerial $ 6 2. 90 (GS

- 13, Step 5, $ 3 9

. 31 + 60% ) Technical $ 4 6

. 67 (GS

- 12, Step 1, $ 2 9

. 17 + 60% ) Clerical $2 5. 25 (GS

- 6, Step 3, $ 15. 78 + 60% ) These rates are from the Office of Personnel Management (OPM) , 20 1 4 General Schedule , which excludes locality

rates of pay

. The rates have been increased by 60 percent to account for the benefit packages available to government employees. Details upon which this estimate is based appear below in Table 2: Average Annual EP A Burden and Cost

– NSPS for Ammonium Sulfate 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, on average over the next three ye ars, approx imately two existing respondents will be subject to the se standard s . It is estimated that no additional respondents per ye ar will become subject. The overall average number of respondents, as shown in the table below, is two per year. The number of respondents is calculated using the following table that addresses the three ye ars covered b y this ICR :10 **Number of Respondents** Respondents That Submit Reports Respondents That Do Not Submit Any Reports

Year (A) Number of Ne w Respondents 1 (B)

Number of Existing Respondents (C)

Number of Existing Respondents that keep records but do not submit reports (D) Number of Existing Respondents That Are Also New Respondents (E)

- counting respondents

. As shown above, the average Number of Respondents over the three ye ar period of this ICR is two

. The total number of annual responses per ye ar is calculated using the following table: **Total Annual Responses** (A) Information Collection Activity (B) Number of Respondents (C)

Number of Responses (D)

Number of Existing Respondents That Keep Records But Do Not Submit Reports (E) Total Annual Responses E=(BxC)+D

Semiannual Reports 2 2 0 4 Total 4 The number of Total Annual Responses is 4. The total annual labor costs are $28,700

. 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)

. **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 below , respectively , and summarized below.

**(i) Respondent Tally**11

The total annual labor hours are 286 hours

. 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)

. We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the ty

pical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the ty pical duties of clerical staff are to proofread the reports, make copies and maintain records. Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 72 hours per response

. The total annual capital/startup and O&M costs to the regulated entity are $0

. 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 37 labor hours at a cost of $1,670

. See (below) Table 2: Average Annual EPA Burden and Cost

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

. We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the ty

pical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the ty pical duties of clerical staff are to proofread the reports, make copies and maintain records. **6(f) Reasons for Change in Burden**  There is an increase of two labor hours from the most recentl y approved ICR due to a change in assumptions

. The previous ICR assumed that only new respondents would spend time to read and review the regulatory requirements. This I CR assumes that each respondent will spend one hour annually

re - familiarizing themselves with the rule. **6(g) Burden Statement**  The annual public reporting and recordkeeping burden for this collection of information is estimated to average 72 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; develop, acquire, install, and utilize technology and s ys tems for the purposes of collecting, validating, and verifying information, processing and maint aining information, and disclosing and providing information; adjust the existing way s to compl y with any previously

applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data12

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 CF R Chapter 15.

b. This ICR uses the following labor rates: Technical $103.97 ($49.51 + 110%); Managerial $129.93 ($61.87+ 110%); and Clerical $ 51.79 ($24.66 + 110%). These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2014, “Table 2. Civilian Workers, by o ccupational and industry group.” The rates are from column 1, “Total compensation.” The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry. This ICR assumes that Managerial hours are 5 percent of Technical hours, and Clerical hours are 10 percent of Technical hours

.
c. We assumed that eac h respondent will spend one hour each year to read and understand the rule requirements. d. 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 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 reco rds will be recorded 365 days per year. h. Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.16
