NATIONAL EMISSION STANDARDS FOR MINERAL WOOL PRODUCT ION

PART A

1.0 Identification of the Information Collection

(a) Title and Number of the Information Collection.

“National Emission Standards Mineral Wool Production.” This is a new information collection request (ICR), and the EPA tracking number is 1799.06. (b) Short Characterization. This ICR covers information collection requirements in the final amendments to the Mineral Wool Production NESHAP (40 CFR part 63, subpart DDD)

. The potential respondents are owners or operators of a ny existing, new, or reconstructed mineral wool production facilities. There are an estim ated 8 facilities subject to the Mineral Wool Production NESHAP. The affected source is any mineral wool production facility that is engaged, either in part or in whole, in the production of mineral wool and that is located at a plant site that is a major source as defined in 40 CFR part 63.2. The final amendments would require cupolas to meet emissio n limits for COS; 3 new subcategories of combined collection/curing operations to meet revised emission limits for formaldehyde and new emission limits for phenol and meth anol; and affected sources to meet new requirements for periods of startup and shutdown. The final emission limits for COS can be met by cost effective measures such as changes in raw mate rials and the other final emission limits are currently being met by all facilities. These amendment s are explained further in the following paragraphs. The information collection requirements associated wit h the final amendments to the

NESHAP are listed in Attachment 1.

2. Need For and Use of the Collection (a) Need/Authority for the Collection

.2

Section 112 of the Clean Air Act (CAA) requires EPA to establish NESHAP for both major and area sources of HAP that are listed for regula tion under CAA section 112(c). A major source is a stationary source that emits or has the po tential to emit more than 10 tons per year (tpy) of any single HAP or more than 25 tpy of any combi nation of HAP. An area source is a stationary source that is not a major source (i.e., a n area source does not emit and does not have the potential to emit more than 10 tpy of any single HAP and more than 25 tpy of any combination of HAP). For major sources, these techn ology-based standards must reflect the maximum degree of emission reductions of HAP achievable (after considering cost, energy requirements, and non-air quality health and environmenta l impacts) and are commonly referred to as maximum achievable control technology (MACT) standa rds. Section 112(d)(6) requires EPA to review these technology-based standards and to revise them “as necessary (taking into account developments in practices, processes, and control techno logies)” no less frequently than every 8 years. In addition, section 112(f) of the CAA requires EP A to determine for source categories subject to certain CAA section 112(d) standards whether th e emissions limitations provide an ample margin of safety to protect public health. For MA CT standards for HAP “classified as a known, probable, or possible human carcinogen" that "do n ot reduce lifetime excess cancer risks to the individual most exposed to emissions from a source in the category or subcategory to less than 1-in-1 million,” EPA must promulgate residual risk stan dards for the source category (or subcategory) as necessary to provide an ample margin of s afety to protect public health. In doing so, EPA may adopt standards equal to existing MACT standards , if EPA determines that the existing standards are sufficiently protective. EPA must also adopt more stringent standards, if necessary, to prevent an adverse environmental effect , but must consider cost, energy, safety, and other relevant factors in doing so. Certain records and reports are necessary for the Admi nistrator to confirm the compliance status of sources subject to NESHAP, identify any new o r reconstructed sources subject to the standards, and confirm that the standards are being achie ved on a continuous basis. These recordkeeping and reporting requirements are specifically auth orized by section 114 of the Clean Air Act (42 U.S.C. 7414) and set out in the part 63 NESHAP Gen eral Provisions. The recordkeeping and reporting requirements for title V permits are contained in 40 CFR 70.6 and 403

CFR 71.6. Under parts 63 and 70 or 71, the owner or operator mus t keep each record for 5 years following the date of each occurrence, measurement, mai ntenance, corrective action, report, or

record. (b) Use/Users of the Data. The information will be used by the delegated authority (State agency, or Regional Administrator if there is no delegated State agency) to ensure that the standards and other requirements are being achieved. Based on review of the recorded information at the site and the reported information, the delegated permitting authority ca n identify facilities that may not be in compliance and decide which facilities, records, or proce sses may need inspection.

3. Nonduplication, Consultations, and Other Collection Criteria (a) Nonduplication. A computer search of EPA’s ongoing ICRs revealed no duplica tion of informationgathering efforts. (b) Public Notice Required Prior to ICR Submission to OMB. This section is not applicable because this is a rule-r elated ICR. (c) Consultations. The final amendments were developed in consultation with individual companies, State agencies, and trade associations. The non-EPA persons consulted on the information collection

activities are identified in Table 1.

(d) Effects of Less Frequent Collection. If the relevant information was collected less freque ntly, the delegated permitting authority (State or EPA) will not be reasonably assured that a facility is in compliance with the standards. (e) General Guidelines. None of the guidelines in 5 CFR 1320.6 are being exceeded. (f) Confidentiality. All information submitted to the Agency for which a c laim of confidentiality is made will be safeguarded according to the Agency policies set forth i n Title 40, Chapter 1, Part 2, Subpart B--Confidentiality of Business Information (see 40 CFR 2; 41 FR 36902, September 1, 1976; amended by 43 FR 39999, September 28, 1978; 43 FR 42251, September 28, 1978; 44 FR 17674, March 23, 1979). (g) Sensitive Questions. This section is not applicable because this ICR does n ot involve matters of a sensitive

nature. 4. The Respondents and the Information Requested (a) Respondents/NAICS Codes. Potential respondents under subpart DDD are owners or oper ators of any existing or new facility engaged in mineral wool production operations. M ineral wool production facilities are primarily classified under NAICS code 327993, Mineral Wool Man ufacturing. There are an estimated 8 existing facilities that would be subject to the final amendments to the NESHAP. We are not aware of any new mineral wool production facilities that will be constructed and in production during the 3-year period of this ICR. (b) Information Requested. (i) Data Items, Including Recordkeeping Requirements. Attachment 1, Information Requirements, summarizes the data items, including recordkee ping and reporting requirements, for the Mineral Wool Production source category. (ii) Respondent Activities. The respondent activities that will be required by the final

amendments to the Mineral Wool Production NESHAP are i dentified in Table 2 and are introduced in section 6(a).5

5. The Information Collected–Agency Activities, Collection Met hodology, and Information Management (a) Agency Activities. The Agency activities associated with the final amen dments to the Mineral Wool Production NESHAP are provided in Table 3 and are introduced in section 6(c). (b) Collection Methodology and Management

. Data and records maintained by the respondents are tabul ated and published for use in compliance and enforcement programs of the delegated permit ting authority. EPA is the permitting authority until the State agency is delegated aut hority to implement the final amendments to the rule. Therefore, information conta ined in any report submitted to the Regional Administrator will be entered into the Air Facility S ystem (AFS), which is operated and maintained by EPA’s Office of Compliance. AFS is EPA ’s database for the collection, maintenance, and retrieval of compliance data for approx imately 125,000 industrial and government-owned facilities. EPA uses the AFS for tra cking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices and EPA headquarters. EPA and its delegated authorities can edit, store, retrie ve and analyze the data. (c) Small Entity Flexibility.

The Small Business Administration defines a small ent ity engaging in mineral wool production operations as a firm having no more than 500 empl oyees. There are six companies operating the 8 mineral wool production facilities and fiv e of the six companies are small

businesses. The final amendments would not result in si gnificant adverse impacts on any of the

small entities in the Mineral Wool Production source c ategory. The impacts to most producers affected by this final rule are annualized costs of les s than one percent of their revenues using the most current year available for revenue data. The fin al amendments would create new requirements for compliance testing for existing sources and associated notification requirements, recordkeeping, and reporting requirements. (d) Collection Schedule

. The specific frequency for each information collectio n activity within this request is shown in Table 2 for the Mineral Wool Production Source Catego ry.6

6. Estimating the Burden and Cost of the Collection (a) Estimating Respondent Burden.

The annual burden estimates for the final amendments t o the Mineral Wool Production

NESHAP are shown in Table 2. These numbers were deriv ed from estimates based on EPA’s experience with other standards. No burden estimates ar e provided for new sources because no new facilities are expected to become affected sources during the 3-year period of this ICR. (b) Estimating Respondent Costs.

The information collection activities for the fina l amendments to the Mineral Wool Production NESHAP are presented in Table 2. Because the data are already collected by respondents as part of normal operations, no respondent de velopment costs are associated with

the information collection activities. (i) Estimating Labor Costs . Labor rates and associated costs are based on Bureau of Labor Statistics (BLS) data. Technical, management, and clerical average hourly rates for private industry workers were taken from the United States Depart ment of Labor, Bureau of Labor Statistics, Occupational Employment and Wages, May 2014 avai lable at http://www.bls.gov/oes/current/naics4_327200.htm . Wages for technical labor are based on "Glass and Glass Product Manufacturing – architectural and e ngineering," with a total compensation of $34.74/hour. Wages for management labor are taken from "Glass and Glass Product Manufacturing – management, business, and financial, " with a total compensation of $53.31/hour. Wages for clerical labor are based on "Glass and Glass Product Manufacturing – production, planning, and expediting clerks," with a total co mpensation of $20.36/hour. These rates represent salaries plus fringe benefits and do not include the cost of overhead. An overhead rate of 110 percent is used to account for these costs. T he fully-burdened hourly wage rates used to represent respondent labor costs are: technical at $72.95/hour, management at $111.95/hour, and clerical at $42.76/hour. (ii) Estimating Capital and Operations and Maintenance (O&M) Costs . No capital costs

or O & M costs are associated with the information c ollection requirements of the final

amendments to the Mineral Wool Production NESHAP. The final amendments would not require7

affected facilities to purchase new monitoring systems, but would require all facilities to conduct new performance testing to demonstrate compliance with the new emission limits. (iii) Annualizing Capital Costs . No capital costs are associated with the informati on collection requirements of the final amendments to the Mineral Wool Production NESHAP. (c) Estimating Agency Burden and Cost

. Because the information collection requirements were developed as an incidental part of standards development, no costs can be attributed to the development of the information collection requirements. Because reporting and recordkeepin g requirements on the part of the respondents are required under the operating permits rules in 40 CFR part 70 or part 71 and the part 63 NESHAP General Provisions, no operational costs will be incurred by the Federal

Government. Publication and distribution of the inform ation are part of the Compliance Data System, with the result that no Federal costs can be directly attributed to the ICR. Examination of records to be maintained by the respondents will occ ur incidentally as part of the periodic inspection of sources that is part of EPA’s overall co mpliance and enforcement program, and, therefore, is not attributable to the ICR. The only costs that the Federal government will incur are user costs associated with the analysis of the reporte d information, as presented in Table 3. The Agency labor rates are from the Office of Perso nnel Management (OPM) 2015 General Schedule, which excludes locality rates of pay. These rates can be obtained from Salary Table 2013-GS available on the OPM website, http://www.o pm.gov/policy-data-oversight/payleave/salaries-wages/salary-tables/pdf/2015/GS_h.pdf. The gove rnment employee labor rates are $15.94/hour for clerical (GS-6, Step 3), $29.46 for technical (GS -12, Step 1), and $39.70/hr for management (GS-13, Step 5). These rates were increased b y 60 percent to include fringe benefits and overhead. The fully-burdened wage rates used to represen t Agency labor costs are: clerical at $25.50/hour; technical at $47.14/hour, and management at $63.52/hour

(d) Estimating the Respondent Universe and Total Burden and Costs

. There are an estimated 8 existing facilities that are subject to the Mineral Wool Production NESHAP. Consequently, the average number of mineral wo ol respondents during the 3-year period of this ICR is 8 divided by 3 = 2.67.

For the final amendments to the Mineral Wool Productio n NESHAP, the components of

the total annual burden attributable to this ICR include reading the amendments to the NESHAP; conducting the performance testing to demonstrate complian ce with the final emission limits; and reporting the results of those emissions tests; all ot her recordkeeping and reporting activities are already accounted for in the ICR for the NESHAP. (e) Bottom Line Burden Hours and Cost Tables. (i) Respondent tally. The bottom line respondent burden hours and costs, prese nted in Table 2 are calculated by adding person-hours per year down e ach column for technical, managerial, and clerical staff, and by adding down the cos t column. The average annual burden for the recordkeeping and reporting requirements in the fina l amendments to subpart DDD for the 8 facilities that are subject to the Mineral Wool Pro duction NESHAP is 123 person-hours, with an annual average cost of $25,150. No capital costs would be expected for the final amendments. (ii) The Agency tally. The average annual Federal Government cost is $1,465 for 25 hours for the final amendments to subpart DDD. The bo ttom line Agency burden hours and costs presented in Table 3 are calculated by adding person-h ours per year down each column for technical, managerial, and clerical staff, and by adding down the cost column. (iii) Variations in the annual bottom line. This section does not apply since no significant variation is anticipated. (f) Reasons for Change in Burden. This section does not apply because this is a new ICR. (g) Burden Statement The average annual respondent burden for the final amendm ents to the Mineral Wool Production NESHAP is estimated at 40 hours per facility. Burden means the total time, effort, or financial res ources expended by persons to generate, maintain, retain, or disclose or provide info rmation to or for a Federal agency. This9

includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, an d verifying information, processing and maintaining information, and disclosing and providing infor mation; adjust the existing ways to comply with any previously applicable instructions and requi rements; train personnel to be able to respond to a collection of information; search data so urces; complete and review the collection of information; and transmit or otherwise disclose the i nformation. An agency may not conduct or sponsor, and a person is no t required to respond to a collection of information unless it displays a currentl y valid OMB control number. The OMB control numbers for EPA’s regulations in 40 CFR part 63 are listed in 40 CFR part 9. To comment on the Agency’s need for this information the accuracy of the provided burden estimates, and any suggestions for minimizing respon dent burden, including through the use of automated collection techniques, EPA has establis hed a public docket for this ICR under Docket ID No. EPA-HQ-OAR-2010-1041, which is available for o nline viewing at http://www.regulations.gov , or in person viewing at the Air and Radiation Docket a nd Information Center in the EPA Docket Center (EPA/DC) , EPA West, Room B-102, 1301 Constitution Ave., NW, Washington, DC.
