Information Collection Request

1. Identification of the Information Collection

1(a). Title and Number of the Information Collection

Information Requirements for Locomotives and Locomotive Engines (Final Rule for Locomotive and Marine Engines)

ICR Tracking Number: 1800.05

1(b). Short Characterization / Abstract

The Clean Air Act authorizes EPA to adopt emission standards for new nonroad engines. EPA needs information to verify that manufacturers comply with emission standards – before production begins, during production, and after units have been placed into service. In the rulemaking we require manufacturers to generate or retain information to demonstrate that engines comply with emission standards.

Manufacturers generally send us the data they collect and keep these records and other pertinent information. We may request to see any of these records.

EPA and the regulated companies will use the data exclusively to ensure compliance with emission standards. Information such as engine family, total numbers of engines built, and emission rates for specific pollutants, are examples of what we require.

This ICR is a revision to the existing information collection approved under OMB control number 2060-0392. The revisions generally include new standards, testing, and reporting requirements for nonroad diesel engines.

It has been estimated that a total of seven locomotive engine manufacturers and remanufacturers will respond to this collection with an approximate total cost of $3.3 million annually

2. Need for and Use of the Collection

2(a). Need / Authority for the Collection

The data EPA requires in this ICR is necessary to comply with Title II of the Clean Air Act, as amended in 1990. The Act directs us to adopt regulations for nonroad engines if we determine those engines contribute significantly to air pollution in the U.S. Now that EPA has made this determination, the Act directs the Agency to set emission standards for any category of nonroad engines that contributes to air quality nonattainment in two or more areas in the U.S. EPA can only meet the requirements of the Act by collecting data from the regulated industry. Also, EPA will only have an effective program if we know that these engines maintain their certified emission level throughout their operating lives.

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

EPA will oversee the certification process and maintain the program database and use the data items to verify compliance with the following requirements associated with the new emission standards.

• Determine whether or not a prototype engine may adequately represent an engine family

• Ensure compliance of production-line engines

• Ensure compliance of in-use engines

• Issue a recall to correct a noncompliant family of engines

• Confirm actual emission benefits gained by the program

• Ensure proper maintenance and setting of physically adjustable parameters

• Aid in the production projections to randomly select the engines which are to undergo testing

• Determine whether a prototype or freshly manufactured engine should be issued a certificate of conformity

• Ensure that durability of emission controls is consistent with the manufacturer's stated useful life

• Ensure control of emissions across the range of engine operation expected in the normal course of its lifetime

• Manage the importation of engines that meet requirements

3. Non-duplication, Consultations, and Other Collection Criteria

3(a). Non-duplication

The information requested under this ICR is required by statute. Because of its specialized (and sometimes confidential) nature, and the fact that most of it must be submitted to EPA before locomotives and locomotive engines can be sold, the information collected is not available from any other source. Furthermore, some of the information requested under the AB&T program –such as actual sales volumes- is claimed as confidential business information (CBI) by manufacturers; therefore EPA can only obtain it if manufacturers submit it. Participation in the AB&T program is voluntary.

3(b). Public Notice Required Prior to ICR Submission to OMB

EPA published a proposed rulemaking in the Federal Register, (72 FR 15937) on April 3, 2007 (http://www.epa.gov/fedrgstr/EPA-AIR/2007/April/Day-03/a1107a.htm) regarding emission standards for locomotives and locomotive engines. The proposed rule included invitations to comment on the ICR. EPA had already received comments on several issues related to information collection as part of our effort to develop the proposal. All comments and our responses are reflected in the final rule and this ICR for the final rule.

3(c). Consultations

EPA has met with companies that will be subject to the new emission standards. These contacts are summarized as follows:

Contact: Steve Fritz

Company: Southwest Research Institute (testing laboratory)

Phone: 210-522-3645

Contact: Vish Talekar

Company: General Electric (locomotive manufacturer)

Phone: 814-875-6924

3(d). Effects of Less Frequent Collection

Annual reporting for certifying engine families is necessary to align with the regulatory requirement to certify engine families every year. Quarterly reporting of results from production-line testing is necessary to allow adequate response to any problem that may arise. Quarterly reporting of AB&T credit balances ensures that manufacturers hold valid credits and warns manufacturers in advance of the need to acquire credits. Manufacturers must not have a negative credit balance at the end of the year. In-use testing reports must be submitted once per year, within three months of the completion of the required testing. Providing this information to EPA at a less frequent interval would compromise the Agency's ability to expeditiously evaluate the emissions results and determine, in a timely manner, whether in-use locomotives conform to emission standards.

3(e). General Guidelines

This ICR complies with the general guidelines, except for the requirement to retain records for up to eight years, as described in 4(b)(i) and (ii) below.

According to 40 CFR 92.215(a)(3), 92.308(d) and 92.509(b), certification, AB&T and PLT related records must be maintained for eight years. However, “records may be retained as hard copy or reduced to computer disks, etc., depending on the record retention procedures of the manufacturer or remanufacturer”, provided that in every case all the information contained in the hard copy is retained. These recordkeeping requirements stem mainly from the statutory requirement to warrant some items for long periods of time and because locomotive have extremely long useful lives. In addition, the manufacturers must comply with requirements to recall vehicles and engines failing to meet emission standards during their useful lives.

Manufacturers are required to submit confidential business information such as sales projections and certain sensitive technical descriptions (please see section 4(b)(i) for reference). This information is kept confidential in accordance with the Freedom of Information Act, EPA regulations at 40 CFR Part 2, and class determinations issued by EPA's Office of General Counsel. Also, non-proprietary information submitted by manufacturers is held as confidential until the specific locomotive or locomotive engine to which it pertains is available for purchase.

No other general guideline is exceeded by this information collection.

3(f). Confidentiality

EPA holds information from the engine manufacturers as confidential until the associated engines are available for purchase. Manufacturers may submit proprietary information, consisting generally of sales projections and certain sensitive technical descriptions. EPA grants confidentiality in accordance with the Freedom of Information Act, EPA regulations at 40 CFR part 2, subpart B, and class determinations issued by our Office of General Council.

3(g). Sensitive Questions

No sensitive questions are asked in this information collection.

4. The Respondents and the Information Requested

4(a). Respondents / NAICS Codes

Respondents are manufacturers of nonroad equipment and engines within the following North American Industry Classification System codes:

333618 Other Engine Equipment Manufacturing

336510 Railroad Rolling Stock Manufacturing

482111 Line-haul Railroads

4(b). Information Requested

(i). Data Items

A. Certification:

To obtain a certificate of conformity, all manufacturers and remanufacturers must describe their products and supply test data to verify compliance. This information is organized by "engine family" groups expected to have similar emission characteristics. The burden associated with certifying a given engine family is reduced after the first production year (model year), because data and information from previous years can be "carried over" when no significant changes have occurred. For instance, an engine family certified in model year 2009 can be certified in the 2010 model year by "carry over" of data and paperwork from the 2009 model year if no significant changes have occurred to the engine family between model years. Allowing manufacturers and remanufacturers to "carry over" data and paperwork saves them the burden of duplication of data and paperwork which would occur in the absence of such provisions. Manufacturers and remanufacturers must also retain records.

Manufacturers must keep records for eight years, except routine emission records. Manufacturers must keep routine emission records for only one year.

When a manufacturer or remanufacturer needs to make changes to a certified engine, or to add an engine model to an already certified engine family, the following information must be submitted. Running changes are submitted using the same electronic format used to apply for a certificate of conformity.

B. Averaging, Banking, and Trading (AB&T):

To participate in the AB&T program, manufacturers and remanufacturers submit calculations of the amount of credits they generate or need to certify each locomotive family, based on each family’s emission limit and sales volume. Participation in the program is voluntary.

Since all new locomotives and locomotive engines are required to meet both the line-haul and switch duty-cycle standards, manufacturers and remanufacturers can participate in separate line-haul and switch AB&T programs. They cannot, however, use credits generated under one program to satisfy the requirements of the other. Credits can only be generated for NO_x and PM. Only manufacturers and remanufacturers of new locomotives and new locomotive engines manufactured or remanufactured in the 1999 model year or later can participate. Failure to submit and keep accurate information can result in EPA voiding the certificate of the affected family ab initio, among other penalties.

Records are to be kept for eight years.

C. Manufacturer Production-Line Testing (PLT) and Remanufacturer Installation Auditing

Information requested under the PLT program consists mainly of test results and a description of the locomotives tested and the conditions under which the tests took place. This information is essential to determine if locomotives and locomotive engines are in fact complying with emission standards at different stages. Whereas the certification test information tells us that a specific engine prototype is capable of meeting emission standards, PLT data is used to determine if mass-produced engines also comply.

Only manufacturers of freshly manufactured locomotive engines are subject to PLT requirements. However, if EPA has reasons to believe that there are problems with a remanufacturer’s production, the Agency can extend this requirement to that remanufacturer. EPA can also require manufacturers and remanufacturers to submit or retain additional information not otherwise specified.

Each calendar quarter, manufacturers must conduct testing on a sample of locomotives or locomotive engines taken directly from the assembly line and submit a report of the results.

When a locomotive or locomotive engine fails PLT or an audit, the certificate of conformity issued to that locomotive or locomotive engine family is suspended, effective from the time the testing of that locomotive or locomotive engine is completed. The affected manufacturer or remanufacturer must then remedy the noncomformity, retest or reaudit, and submit reports.

Records must be kept for eight years after completion of all testing.

Each calendar quarter, remanufacturers must audit the installation of locomotives covered by its certificate(s) of conformity for proper components, component settings and component installations on randomly chosen locomotives in an engine family. Within 30 days of the end of each quarter, remanufacturers must submit a report of the results.

D. In-Use Testing

Information requested under the in-use testing program consists mainly of test results and a description of the locomotives tested and the conditions under which the tests took place. This information is essential to determine if locomotives and locomotive engines are in fact complying with emission standards at different stages. Whereas the certification test information tells us that a specific engine prototype is capable of meeting emission standards, in-use data is used to verify that engines are correctly maintained and that they meet the standards at 50% to 75% into their useful lives.

Manufacturers and remanufacturers must test, each year, a sample of used locomotives from one of their certified locomotive engine families previously chosen by EPA. If one manufacturer holds certificates for both freshly manufactured engine families and remanufactured engine families, EPA can request the manufacturer to test one engine family of each category. EPA may request a manufacturer to test more than one engine family if it has reason to believe that engines in an engine family do not comply with in-use standards. Engine families of less than 10 locomotives per year do not need to participate in in-use testing. For each locomotive tested, the manufacturer or remanufacturer must submit a report within 30 days of completion of the testing.

E. Emission-Related Defects

Manufacturers must report to us if they learn that a substantial number of their engines have emission-related defects. This is normally not a requirement to collect information, but if manufacturers learn that there is or might be a substantial number of emission-related defects, then they must send us information describing the defects.

(ii). Respondent Activities

Companies retain records as hard copy and may also reduce the information to microfilm, computer disks, etc. We require very little submission of information to process applications for certification. This reduces the resource burden, both for the industry and for us. However, because we don’t have the information on file, we depend on manufacturers to retain the records to allow us to verify compliance throughout the useful life of the engines. Eight years is sufficient time for this information for most engines. Any investigation of in-use engines generally does not start until three or more years after the manufacturer completes the application for certification.

The certification information includes records related to the deterioration of an engine’s emission controls with age. Some manufacturers also participate in emission-credit programs, in which they produce some engines with emissions above the standard and others with emissions below the standard. This is an optional program, so we don’t include specific estimates related to any additional reporting or recordkeeping for generating or using emission credits.

Manufacturers must also report to us if they learn that a substantial number of their engines have emission-related defects. This is normally not a requirement to collect information, but if manufacturers learn that there is or might be a substantial number of emission-related defects, then they must send us information describing the defects.

5. The Information Collected – Agency Activities, Collection Methodology, and Information Management

5(a). Agency Activities

Our certification and tracking process involves reviewing applications and emission data from engine and vehicle manufacturers. From this data, we issue certificates of conformity. We work with AB&T data to assure engine manufacturers using the program are complying with the requirements of this program. We also collect production line testing information quarterly from freshly manufacturered engines and may extend it to the remanufacturer if EPA has reasons to believe there are problems with a remanufacturer’s production. We run the in-use testing program, in which we select one certified engine families per year for the manufacturer to test. In both the PLT and in-use programs once we receive the results we determine if production and in-use engines continue to comply with standards. We may also select families to be tested in a given production year and require additional testing, based on an analysis of the submitted data.

5(b). Collection Methodology and Management

We currently use a system called VERIFY to collect and store information and expect to continue using it when the regulation becomes effective. Much routine information (test results, projections) can be electronically transmitted directly from the manufacturers to our computer database. We expect to publish this information on our website once certified engines go into production (www.epa.gov/otaq/). Our communications with the regulated entities mainly occurs electronically making it convenient for collection and management.

5(c). Small Entity Flexibility

EPA has exempted remanufactured locomotive and locomotive engines owned by small railroads (as defined by the Small Business Administration) from the definition of ‘new locomotive’ and ‘new locomotive engine’; thus exempting these remanufactured locomotives and locomotive engines from compliance with certain emission standards and regulations. This is due to the fact that the number of locomotives owned and operated by small railroads is very low and that the contribution of these engines to the sector’s emission inventory is considered to be trivial.

Under the In-use Testing Program, locomotive families of less than 10 locomotives are exempted from the requirements of the program. This provision reduces the cost of the program for manufacturers and remanufacturers with limited production.

Under the other programs included in this ICR (AB&T and PLT), the information being requested is considered to be the minimum needed to effectively conduct and maintain their integrity. Further measures to simplify reporting for small businesses do not appear prudent or necessary.

5(d). Collection Schedule

The principal reporting requirements are associated with certification to the emission standards, which begin to apply in the 2008 time frame. Annual reporting is based on the beginning of the model year, which can vary for each manufacturer and for each engine family.

6. Estimating the Burden and Cost of the Collection

Engine manufacturer complies with emission standards by submitting an application for certification, which obligates them to do a certain amount of testing to show they comply with the standards. The following discussion develops burden and cost estimates for the first three years of the program.

6(a). Estimating Respondent Burden

The estimates of respondent burden utilize data from the affected industries or commercially available databases. Burden hours per engine family are based upon established hour amounts for engine families, as published in the “Application for Motor Vehicle Emission Certification and Fuel Economy Labeling” (OMB No. 2060-0104).

The burden for certification testing is generally based on conducting four engine tests for each engine family, then using that test data for several years. The estimated cost for full certification testing, including durability demonstration testing, is $35,000 per engine test (combining labor and O&M expenses). The manufacturer’s application for certification involves an extensive effort the first year, followed by relatively little effort in subsequent years.

The 2007 locomotive certification database lists 76 manufactured and remanufacture engine families. For this cost analysis, EPA estimates that there are 4 manufactured engine families and 72 remanufactured engine families. Tier 0 and Tier 1 locomotives will be redesigned and recertified in the 2008-2010 timeframe. Due to the limited number of fresh engine families per year, and the unknown number of remanufactured engines to be certified in the upcoming years, this cost analysis assumes that all remanufactured engines in the 2007 EPA certification database are to be recertified in 2008. Tier 2 locomotives must recertify in the 2013 timeframe and fresh engine families will be required to meet Tier 3 standards in 2012 and Tier 4 standards in 2015 whose dates are beyond the scope of this ICR.

We estimate that manufacturers will conduct new certification testing every five years and therefore the costs have been estimated on an annual average basis in Table 3.

In addition to testing, manufacturers must prepare the application for certification and maintain appropriate records. We have estimated the cost of these combined activities, which include engineering and clerical effort, to be $9,000 per engine family per certification cycle. As with the testing costs, we are presenting annual average costs in Table 3. Costs for certification application include fees assessed at $802 per family per year.

Manufacturers of new engines are also expected to conduct testing on their engines after they have been produced to confirm that they are built to the same tolerances as the certification engine. We base the estimated costs on conducting a minimum of 5 tests per engine family, at approximately $35,000 per test.

Remanufacturers are expected to conduct a production line audit on their engines after they have been remanufactured to confirm that they are remanufactured using the proper parts and procedures. We base the estimated costs on technician, manager and clerical hours to conduct and report the audit. There are no testing costs associated with the audit.

Manufacturers are also expected to conduct testing on their engines after they have been placed into service to confirm that they continue to meet emission standards. Testing selected families using field-testing equipment instead of full laboratory equipment allows for substantial data collection for much lower costs than would be incurred by pulling engines out and testing them on a dynamometer. We base the estimated costs on testing 10 percent of engine families, at approximately $35,000 per family. This allows for testing multiple engines in each family.

These burden estimates apply equally whether the manufacturer conducts the required activities, or if the manufacturer hires a third party for some of these activities.

Participation in AB&T is voluntary for all sectors. Reports and activities in this program are carried out from a company perspective. Therefore, manufacturers need to submit only one report quarterly and one final report in which they account for their company’s activities under AB&T.

6(b). Estimating Respondent Costs

(i). Estimating Labor Costs

To estimate labor costs, EPA used the Bureau of Labor Statistics’ National Industry-Specific Occupational Employment and Wage Estimates (May 2005) for Engine, Turbine, and Power Transmission Equipment Manufacturing (NAICS Code 333600) and increased by a factor of 1.5 to account for benefits and overhead. The specific rates used are listed below. These are mean hourly rates.

Table 1: Labor Costs Estimates

Occupation	SIC Code Number	Mean Hourly Rate (BLS)	Adjusted for Benefits & Overhead
Mechanical Engineering Technician	17-3027	$25.56	$38.34
Engineering Managers	11-9041	$47.49	$71.24
Secretaries, Except Legal, Medical and Executive	43-6014	$15.62	$23.43

(ii). Estimating Capital and Operations and Maintenance Costs

Operation and maintenance costs include expenses related to engine testing. Costs are for laboratory time, the use of test equipment, engine parts, fuel and other supplies, and fabrication of test tools and fixtures. Direct labor costs and operations and maintenance costs combine for the total test costs described above.

Engine manufacturers are required to pay a fee every model year when submitting an application for a certificate of conformity. This fee is requested under the authority of the CAA Section 217. Manufacturers and remanufacturers of locomotives and locomotive engines pay a fee of $802 per application per model year.

(iii). Capital / Start Up Costs vs. Operating and Maintenance (O&M) Costs

Companies required to conduct testing generally either have testing facilities or are expected to conduct testing at a contractor’s laboratory. Thus, no capital or startup costs are anticipated for purchasing emission testing equipment.

(iv). Annualizing capital costs

With no estimated capital or start-up costs, there is no need to annualize these costs.

6(c). Estimating Agency Burden and Cost

The Heavy-Duty and Nonroad Engine Group (HDNREG) administers emission certification programs. The group has approximately 17 full-time employees. We project 50 hours per week of staff time (at $75 per hour, loaded) to manage engine compliance programs related to new emission standards. This comes to approximately 2,600 hours or $195,000 per year to oversee the requirements of the programs associated with this ICR.

Table 8

Table 2: Agency Labor Costs

Occupation	Hourly Rate	160%
Engineer (GS-13/6)	$44.39	$71.02
Lawyers (GS-14/5)	$50.95	$81.52
Managers (GS-15)	$52.88	$84.61
SES-1	$89.42	$143.08

The salary of a senior from the Senior Environmental Employment (SEE) Program for clerical support is $13.81 per hour plus approximately 150% increase for benefits, for a total of $20.72. EPA also pays a $2,151.83 administrative fee to Senior Services America, Inc., the organization from which our SEE Employees come. This data was obtained from HDNEG's financial officer. To calculate how much of that fee corresponds to this collection, the fee was divided by the number of hours the senior spends in this program and added to the hourly salary rate for a total of $24.38.

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

The EPA certification database includes 76 engine families of fresh and remanufactured engine families. All of the remanufactured engine families, 72, are assumed to be used in Tier 0 and Tier 1 locomotives and are assumed to be recertified in 2008.

Based on current usage of the AB&T program, we estimate 14 engine families will be part of the AB&T program. All fresh locomotive engine manufacturers must participate in the PLT program and both manufacturers and remanufacturers must participate in the In-Use Testing Programs.

Table 3 shows the labor and other costs associated with meeting the existing and new requirements for each engine family. This includes certification costs, plus the cost of any additional testing. Per-family costs are multiplied by the number of engine families and added to estimated capital costs (if any) to arrive at an estimated total cost.

6(e). Bottom Line Burden Hours and Cost Tables

(i). Respondent Tally

Bottom-line burden and cost for the first three years of the rulemaking (2008-2010) are shown in the Table 4. The table shows industry totals and average values for each respondent by category. Seven engine manufacturers and remanufacturers are assumed to be required to do engine redesign and certification testing.

Table 4: Summarized Costs per Respondent

Number of Respondents	Industry Totals				Average per Respondent
	Annualized Capital Costs	Total O&M Costs per Year	Total Hours per Year	Total Costs per Year	Total Hours per Year	Total Costs per Year
9	$0	$2,479,461	21,288	$3,333,384	3,041	$354,209

(ii). The Agency Tally

Our estimated burden is approximately 2,600 hours per year (or $195,000) to oversee the requirements of the programs associated with this ICR, as described in Section 6(c).

6(f). Reasons for Change in Burden

We are proposing emission standards for locomotives and locomotive engines. This information collection request updates the estimated burden to reflect the additional effort required to meet the new standards and consolidates all the various recordkeeping and reporting items for these engines. We are also updating the number of engine families expected to be certified to these standards in the future.

Current ICR Burden: 21,288 hours

Previous ICR Burden: 17,074 hours

Change: 4,214 hours

There is an increase of 4,214 hours in the total estimated burden for ICR 1800.05 currently identified in the OMB Inventory of Approved ICR Burdens. This increase is due to an increase in the total number of applications for certification submittal under this collection. Although the number of respondents remains the same (seven), the 2007 certification database lists 76 applications for certification. In addition, the certifications for 2008 are assumed to involve engine redesign and re-certification testing for 72 of the 76 engine families in the certification database. Testing costs impact the overall time and cost.

6(g). Burden Statement

The annual public reporting and recordkeeping burden for this collection of information is estimated to average 110 hours per response. Burden means the total time, effort, or financial resources expended by 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 systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways 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 currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.
