**SUPPORTING STATEMENT ENVIRONMENTAL PROTECTION AGENCY** 
**NSPS for Metallic Mi neral Processing Plants (40 CFR**  **P art 60,**  **S ubpart LL) (Renewal)** 
**1. Identification of the Information Collection 1(a) Title of the Information Collection**  NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL) (Renewal) EPA I CR Number 0982.10, OMB Control Number 2060

- 0016 **1(b) Short Characterization/Abstract** The New Source Performance Standards (NSPS) for the regulations published at 40 CFR part 60, subpart LL, Metallic Mineral Processing Plants, were proposed on August 24, 1982 , promulgated on February 21, 1984 , and amended on October 17, 2000

. These regulations apply t o the following facilities at metallic mineral processing plants: each crusher and screen in open - pit mines; each crusher, screen, bucket elevator, conveyor belt transfer point, thermal dryer, product packaging station, storage bin, enclosed storage area, truck loading and unloading station at the mill or concentrator, commencing construction, modification or reconstruction after the date of proposal. The NSPS does not apply to facilities located in underground mines, or to facilities performing the beneficiation of uranium ore at uranium ore processing plants, commencing construction, modificatio n or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR part 60, subpart LL. In general, all NSPS standards require initial notifications, performance tests, and periodic reports. Owners or op erators 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 s ys tem is inoperative. These notifications, reports, and records are essential in determining compliance and are required of all sources subject to NSPS. 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 two years fol lowing the date of such measurem ents, maintenance reports, and records. All rep orts are sent to the delegated s tate or local authority . In the event that there is no such delegated authority, the reports are sent directly to the United States Environment al Agency

(EPA) regional o ffice. Approximately

2 0 sources are currentl y s ubject to the regulation, and it is estimated that no additional sources per ye ar will become subject to the regulation in the next three years. However, we estimate that one of the existing source s per year will engage in reconstruct ion or make a phy sical or operational change. This information was confirmed with the rule lead addressing this source category

at the Office of Air Quality Planning and Standards (OAQPS). There are ap proximately 20 metallic mineral processing plants in the United States, which are owned and operated by the metallic mineral processing industry (the “Affected Public”). N one2

of the facilities in the United States are owned by state, local, tribal or the Federal government; all are privatel y, owned for

- profit businesses. The burden to the “Affected Public” is listed in Table 1: Annual In dustry

B urden and Cost

– NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL ) (Renewal). The Federal government burden associated with the review of reports submitted by

the respondent is shown in Table 2: Average Annual EPA Burden

– NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL ) (Renewal). In the development of the Informatio n C ollection R equest (ICR) , we addressed the Office of Management and Budget (OMB) “Terms of Clearance (TOC)” on the active I CR. The TOC are : This collection of information is approved fo r 3 years. Before

resubmission of this ICR, the Agenc y s hould update wage estimates, continuing to refer to most recentl y available data from Bureau of Labor Statistics. In addition, the agency should verify the number of respondent entities. EPA has addressed ea ch item of concern in the TOC. The updated labor rates and the number of respondents have been thoroughly checked , and all estimates have been updated.
**2. Need for and Use of the Collection 2(a) Need/Authority for the Collection**  The EPA is charged under s ection 111 of the Clean Air Act (CAA), as amended, t o 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 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 als o 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 o wner or 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 the3 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 metallic mineral processing plants cause or contribute to air pollution that may reasonably

be anticipated to endanger public health or welfare. Therefore, the NSPS was promulgated for this source category at 40 CFR part 60, subpart LL

. **2(b) Practical Utility/Users of the Data** The recordkeeping and reporti ng requirements in the standard ensure compliance with the applicable regulations which were promulgated in accordance with the Clean Air Act. Ina ddition, the collected information is used for targeting inspections and as evidence in legal proceedings. Performance tests are required in order to determine an affected facility’s i nitial capability to comply

with the emission standard. Continuous emission monitors are used to ensure compliance with the standard at all times. During the performance tests, 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 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 ensure that the pollution control devices are properl y in stalled and operated , that leaks are being detected and repaired, a nd that the standards are being met. The performance test may also be observed. The required semiannual reports are used to determi ne periods of excess emissions, to identify problems at the facility , and to verify operation/maintenance procedures and co mpliance.
**3. Non**
**- duplication, Consultations, and Other Collection Criteria**  The requested recordkeeping and reporting are required under 40 CFR part 60, subpart LL

. **3(a) Non**
**- duplication**  If the subject standards have not been delegated, the information is sent directly 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 h as adopted their 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. Th erefore, no duplication exists.4

**3(b) Public Notice Required Prior to ICR Submission to OMB** An announcement of a public comment period for the renewal of this IC R was published in the Federal Register (7 6 FR 26900 ) on May 9 , 20 11 . 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 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 the EPA Office of Compliance. OTIS is the EPA database for the collection, maintenance, and retrieval of all compliance data. The growth rate for the industry is based on our consultations with the Agenc y’s internal industry experts. Industry trade associations and other interested parties were provided an opportunity to comment on the burden associated with the stan dard as it was being developed. In d eveloping this ICR, we contacted the United States Geological Survey (USGS) at (703) 648

- 5953 , and the National Mining Association (NMA) at ( 202 ) 463

- 2 6 00

. It is our polic y t o respond after a thorough review of comments received since the last ICR renewal as well as those submitted in response to the f irst Federal Register n otice. **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. Req uirements 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 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 reports and notifications for at least five years. T his is consistent with the General Provisions as applied to the standards. E PA believe s 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 ye ars allows the EPA to establish the compliance history of a source, any pattern of non

- compliance, and to determine the appropriate level of enforcement action. EPA has found that the most flagrant violators have violations extending beyond the five ye ars. In addition, EPA would be prevented from pursuing the violators due to the destruction or5

nonexistence of essential records. **3(f) Confidentiality** Any i nformation submitted to the Agency for which a claim of confidentiality i s 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 b y 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979). **3(g) Sensi tive 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 metallic mineral processing plants. The United States Standard Industrial Classification (SIC) codes for the respondents affected b y the standards, which corresponds to The North American Industry Classification System (NAI CS) codes, are listed below for source category description. **Standard (40 CFR Part 63, Subpart LL**  **) SIC Codes**  **NAICS Codes** Iron Ore Mining 1001 21221 Copper Ore and Nickel Ore Mining 1021 212234 Lead Ore and Zinc Ore Mining 1031 212231 Gold Ore Mining 1041 212221 Silver Ore Mini ng 1044 212222 Copper Ore and Nickel Ore Mining 1061 212234 All Other Metal Ore Mining 1099 212299 **4(b) Information Requested** None of these reporting or recordkeeping requirements violate any of the regulations established by

OMB at 5 CFR part 1320, section 1320.5. **(i) Data Items** In this ICR, all the data that is recorded or reported is required b y NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL ) (Renewal)

. A source must make the following reports:6 **Notifications** Notification of construction/reconstruction 60.7(a)(1) Notification of actual startup 60.7(a)(3) Notification of ph ys ical or operational change 60.7(a)(4) Notification of continuous monitoring sy stem (CMS) demonstration 60.7(a)(5) Initial performance test results 60.8(a) Initial performance test 60.8(d) A source must keep the following records: **Recordkeeping** Startups, shutdowns, and malfunctions, periods where the continuous monitoring sy stem is inoperative. 60.7(b) Measurements of both the change in pre ssure of the gas stream across the scrubber and the scrubbing liquid flow rate. 60.385(b) Records are required to 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, internal automation has significantly reduced the burden associated with monitoring and recordkeeping 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 not widel y used. At this time, it is estimated that approximately 1 0 percent of the respondents use electronic reporting.
**Re spondent 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 9 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.7 **Re spondent Activities**  Develop, acquire, install, and utilize technology and sy stems for the purpose of disclosing and providing information. Adjust the existing way s to comply with any previously applicable instructions and requirements. Train personnel to be able to respond to a collection of information. Transmit, or otherwise disclose the information. Currently , sources are using monitoring equipment that provides 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 significantly reduced th e 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. **Agency Activities** Observe initial performance tests and repeat performance tests if necessary

. Review notifications and reports, including performance test reports, excess emissions repor ts, required to be submitted by industry

. Audit facility

records. Input, anal yz e, and maintain data in the Online tracking Information s ys tem ( 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 properl y i nstalled and operational

. P erformance test reports are used b y the Agency to discern a source’s initial capability to comply

with the emission standard, and to not e the operating conditions under which compliance was achieved. D ata and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs. The semiannual reports are used for problem identification, as a ch eck 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 the EPA Office of Compliance. OTIS is the EPA database for the collection, maintenan ce, and retrieval of compliance data for approximately 125,000 industrial and government

- owned facilities. E PA uses OTIS for tracking air pollution compliance and enforcement by l ocal and state regulatory

a gencies, EPA regional offices, and EPA headquarters. EPA delegated Authorities can edit, store, retrieve , and analyze the data.8

The records required b y this regulation must be retained by the owner or operator for two ye ars. **5(c) Small Entity Flexibility** The 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 contro l 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. T o the ex tent 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

f or each information collection activity w ithin this request is shown i n Table 1: Annual In dustry B urden for NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL ) (Renewal). **6. Estimating the Burden and Cost of the Collection** Table 1 documents the computation of individual burdens for the recordkeeping a nd 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 a ppropriate, 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 2,306 (Total Labor Hours from Table 1). Th ese 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) E**  **stimating Labor Costs** This I CR uses the following labor rates:9 Managerial $119.36 ($56.84 + 110%) Technical $99.18 ($47.23 + 110%) Clerical $49.35 ($23.50 + 110%) These rates are from the United States Department of Labor, Bureau of Labor Statistic s, March 2011, "Table 2. Civilian Workers, by Occupational and Industry group." The rates are from column 1, "Total Compensation." T he rates have been increased by 110 percent to account for the benefit packages available to those employed by private ind

ustry

. **(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. 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 average annual cost for capital/startup and operation and maintenance costs to industry over the next three ye ars of the I CR is estimated to be $ 13,000

. **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 th e ICR is estimated to be $ 10,380

.10

This cost is based on the average hourl y labor rate as follows: Managerial $62.27 (GS

- 13, Step 5, $38.92 + 60%) Technical $46.21 (GS

- 12, Step 1, $28.88 + 60%) Clerical $25.01 (GS

- 6, Step 3, $15.63 + 60%)
These rates are from the Office of Personnel Management (OPM) “2011 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 emplo ye es
. Details upon which this estimate is based appear in Table 2: Average Annual EPA Burden, NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL ) (Renewal)

. **6(d) Estimating the Respondent Universe and Total Burden and Costs** Based on our research for this ICR, on average over the next three years, approximately 20 existing respondents will be subject to the standard. It is estimated that no additional respondent per year will become subject to the standard . The overall average number of respondents, as shown i n the table below, is 20 per year. The number of respondents is calculated using the following table that addresses the three ye ars covered b y this ICR. **Number of Respondents**

. The total annual labor costs are $ 220,712 . Details regarding these estimates may be found in Table 1 : Annual Industry Burden and Cost

– NSPS for Metallic Mineral Processing Plant s (40 CFR Part 60, Subpart LL ) ( Renewal). **6(e) Bottom Line Burden Hours Burden Hours and Cost Tables** The detailed bottom line burden hours and cost calculations for the respon dents and the Agency are shown in Tables 1 and 2, respectivel y, and summarized below. **(i) Respondent Tally** The total annual labor hours are 2,306 . Details regarding these estimates may be found in Table 1 : Annual Respondent Burden and Cost: NSPS for M etallic Mineral Processing Plants (40 CFR Part 60, Subpart LL ) (Renewal)

. Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 52 hours per response. The total annual capital/start up and operation and maintenance ( O&M ) costs to the regulated entity are $ 13,000

.

**(ii) The Agency Tally** The average annual Agency burden and cost over the next three years is estimated to be 230 labor hours at a cost of $ 10,380 . See Table 2 : Annual Age ncy Burden and Cost: NSPS for Metallic Mineral processing Plants (40 CFR Part 63, Subpart LL ) (Renewal)

. **6(f) Reasons for Change in Burden**12

There is no change in the labor hours to the respondents in this I CR compared to the previous I CR. After consulti ng the Offi ce of Air Quality Planning and S tandards (OAQPS) and trade associations, our data indicates that there are approximately twenty sources subject to the rule , with no additional new sources over the next three years. However, there is an increa se in the estimated burden cost as currentl y identified in the OMB Inventory

of Approved Burdens. The increase is not due to any program changes. The change in burden is due to the use of the most updated labor rates. **6(g) Burden Statement** The annual public reporting and recordkeeping burden for this collection of information is estimated to average 52 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; 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 comply with any previously

applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. An agency

may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a valid OMB Control Number. The OMB Control Numbers for EPA ’ s regulations are listed at 40 CFR part 9 and 48 CFR chapter 15.

**Assu mptions:**  a We have assumed that there are approximately 20 respondents that will become subject to the r ul e , with no additional new sources over the next three years

. However, we have estimated that one existing source per year will engage in reconstruction or make a physical or operational change. b This ICR uses the following labor rates: $119.36 per hou r for Executive, Administrative, and Managerial labor; $99.18 per hour for Technical labor, and $49.35 per hour for Clerical labor.
