This action is undertaken to consolidate information requirements for the HD & NRCI engine and equipment industries into one ICR for simplification and to eliminate duplicity.  All ICRs address related sets of respondents. Many manufacturers responded to more than one of these ICRs.

      Under Title II of the Clean Air Act (42 U.S.C. 7521 et seq.; CAA), EPA is charged with issuing certificates of conformity for engine prototypes that comply with applicable emission standards.  Such a certificate must be issued before engines produced after these prototypes may be legally introduced into commerce. Table 2 below lists EPA regulations pertaining to the industries covered by this ICR.

      Each model year, engine and vehicle manufacturers wishing to sell their products in the US must obtain a certificate of conformity with criteria pollutant standards. HD engines and vehicles also need to comply with evaporative, greenhouse gas (GHG) emissions and fuel economy standards. The fuel economy data is shared with the National Highway Transportation Safety Agency, which administers the program. There are also recordkeeping requirements.  To apply, manufacturers submit descriptions of their planned production engines, detailed descriptions of emission control systems and test data.  This information is organized by "engine family" groups expected to have similar emission characteristics.

	Engine manufacturers electing to participate in the Average, Banking and Trading (AB&T) Program must submit information regarding the calculation, actual generation and usage of credits in an initial report, end-of-the-year report and final report.  These reports are used for certification and enforcement purposes.  Manufacturers must also maintain records for eight years on the engine families included in the program. 

	The Act also mandates EPA to verify that engine manufacturers have successfully translated their certified prototypes into mass produced engines, and that these engines comply with emission standards throughout their useful lives. Some respondents are required to test a sample of engines as they leave the assembly line. The Production Line Testing (PLT) Program is a self-audit program that allows manufacturers to monitor compliance with statistical certainty while minimizing the cost of correcting errors through early detection. Through Selective Enforcement Audits (SEAs) or similar programs, EPA verifies that test data submitted by manufacturers is reliable and that testing is performed according to EPA regulations. Compliance with emission regulations throughout the useful life of an engine is verified through the In-use Testing (In-use) Programs under which engines are tested after they have served a portion of their useful lives. Not all programs apply to all industries included in this collection.

	Engine and equipment manufacturers who chose to participate in TPEM must submit annual reports and keep records. Equipment manufacturers must also notify EPA of their intent to participate prior to introducing any TPEM engines/equipment into the US market.

	This information is collected by the Compliance Division (CD) within the Office of Transportation and Air Quality, Office of Air and Radiation, U.S. Environmental Protection Agency (EPA).  HD certification and fuel economy data is collected in conjunction with and shared with the National Highway Transportation Administration (NHTSA) for use in their fuel economy programs. All information collected could be used by the Office of Enforcement and Compliance Assurance (OECA) and the Department of Justice for enforcement purposes.  Non-confidential portions of the applications are disclosed in EPA's website and may be used by trade associations, environmental groups, and the public.  The information is usually submitted in an electronic format and it is stored in CD's databases.  

	It has been estimated that a total of 468 engine, vehicle and equipment manufacturers will respond to this collection with an approximate cost of $21,639,590.  Please note that some burden and cost tables referenced in this document are found in the accompanying Excel file.


2.  Need for and Use of the Collection

   2(a) Need/Authority for the Collection

      EPA's emission programs are statutorily mandated; the agency does not have discretion to cease these functions.  The data required is necessary to comply with Title II of the Clean Air Act (42 U.S.C. 7521 et seq.; "CAA" or "the Act"), as amended. The Act charges EPA with developing standards for compounds deemed `pollutants' as defined by the CAA itself, and issue certificates of conformity for those engines and motor vehicle designs that comply with those standards. Such a certificate must be issued before engines and vehicles may be legally introduced into commerce. Section 206(a) of the CAA (42 USC 7521) states: 

      "The Administrator shall test, or require to be tested in such manner as he deems appropriate, any new motor vehicle or new motor vehicle engine submitted by a manufacturer to determine whether such vehicle or engine conforms with the regulations prescribed under §202 of this Act.  If such vehicle or engine conforms to such regulations, the Administrator shall issue a certificate of conformity upon such terms, and for such period (not in excess of one year) as he may prescribe."
      
This charge also applies to nonroad engines and equipment, pursuant to §213(d) of the CAA. The Supreme Court's decision in Massachusetts v. Environmental Protection Agency, 549 U.S. 497 (2007), extended it to greenhouse gases (GHGs) when it ruled that GHGs are in fact pollutants under the CAA. 

      Therefore, engine and vehicle manufacturers may not legally introduce their product into U.S. commerce unless EPA has certified that their vehicles and engines comply with applicable emission standards.  To ensure compliance with the CAA, EPA reviews product information and manufacturers' test results. The agency may also test some vehicles and engines to verify data provided by manufacturers at certification. There are also some regulatory requirements for nonroad equipment manufacturers.

	Section 206(b)(1) of the Act authorizes EPA to inspect and require testing of new vehicles and engines to: (1) verify that a manufacturer's final products comply with EPA standards; (2) assure that the correct parts are installed correctly in each engine; and (3) audit the manufacturer's testing process to ensure testing is being done correctly.  The PLT and SEA Programs fulfill these requirements by inspecting and testing engines taken directly from the assembly line and/or existing fleets, and by auditing the engine manufacturer's testing procedures and facilities. Section 207(b) of the CAA mandates the establishment of methods and testing procedures to ascertain whether certified engines in actual use in fact comply with applicable emission standards throughout their useful lives.  The In-Use Testing and similar programs are implemented in response to that mandate.

      49 USC 32902 requires the National Highway Traffic Safety Administration (NHTSA), in consultation with the Department of Energy and the EPA, to prescribe each model year average fuel economy standards. Under 49 USC 32907, manufacturers are required to submit reports to both NHTSA and EPA demonstrating how they plan to comply with applicable average fuel economy standards. 

   2(b) Practical Utility/Users of the Data  

	EPA uses the information requested under this collection to implement a three-stage compliance assurance system established by the CAA; and for enforcement purposes.  First, certification information is needed to verify that the proper prototype engines have been selected to represent each engine/vehicle family (group of engines/vehicles expected to have similar emission characteristics), and that the necessary testing has been performed. Based on this information, EPA issues a certificate of conformity.  However, prototypes are often hand-built and not typical of assembly line engines. Information collected under the PLT and similar programs is used to verify that manufacturers have successfully translated their prototypes into mass-produced engines.  Engines are taken directly from the assembly line and tested. Lastly, in-use testing is designed to determine if engines and vehicles maintained in accordance with the manufacturer's instructions still emit at acceptable levels after a prescribed number of years of actual use.  If a family of engines or vehicles is found not to comply, manufacturers are required to recall the family.  
      
	Flexibility programs such as AB&T and TPEM ease the burden of EPA regulations on regulated parties who choose to participate.

	The information will be received and used by various divisions within CD and NHTSA.  In instances of noncompliance, the information may be used by the EPA's and NHTSA's enforcement offices and the Department of Justice.  Non-confidential portions of the information submitted to CD are available to and used by importers, environmental groups, members of the public and state and local government organizations. 


3.  Nonduplication, Consultations and Other Collection Criteria

   3(a) Nonduplication

      The information requested under this ICR is required by statute.  Because of its specialized nature, and the fact that most of it must be submitted to EPA before engines and vehicles can be sold, the information collected is not available from any other source.  Furthermore, some of the data requested, such as sales volumes or certain engine designs, may be proprietary in nature, and thus claimed as confidential business information (CBI) by manufacturers.  Therefore, EPA can only obtain the information if it is submitted by its owners. 

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

	An announcement of the public comment period for this ICR revision was published in the Federal Register (83 FR 24992) on May 31, 2018 which can be accessed through the Federal Register's website at http://www.gpoaccess.gov/fr/index.html. Two anonymous comments were received in response to this ICR revision, which can be read by accessing this ICR's docket at https://www.regulations.gov/document?D=EPA-HQ-OAR-2007-1182-0005.

One comment was unfortunately not within the scope of this ICR, as it asked EPA to regulate human waste on the streets. The second comment, which was also submitted verbatim in response to a prior FR notice, states: "Just think of the Billions that could be saved from unfair Regulations and spend on Schools, Healthcare, Budget. American has Good Air and Good Water, please stop beating on this same subject day after day;" and proceeds to quote average pollution statistics from the World Health Organization for 3 American cities during one month in 2018. While we appreciate this concern, we'd like to point out that, while the direct costs of some of the measures called for in the 1990 amendments to the Clean Air Act (not counting the implementation of the original 1970 CAA) have been assessed at $65 Billion by 2020; its direct benefits at $2 Trillion, a 31:1 ratio. The World Health Organization (organization cited by the commenter)'s own report Cost of the Health Impact of Air Pollution in Europe  -  Clean Air, Health and Wealth available at cites those figures on page 34. 
      
      
      Furthermore, the chart Comparison of Growth Areas and Emissions, 1980-2017 from EPA's 2017 Air Trends Report shows that "between 1980 and 2017, gross domestic product increased 165 percent, vehicle miles traveled increased 110 percent, energy consumption increased 25 percent, and U.S. population grew by 44 percent. During the same time period, total emissions of the six principal air pollutants dropped by 67 percent. The graph also shows that between 1980 and 2016, CO2 emissions increased by 12 percent. Despite great progress in air quality improvement, approximately 111 million people nationwide lived in counties with pollution levels above the primary [National Ambient Air Quality Standards, NAAQS] in 2017." While we are happy to see that long term efforts by people in all levels of government, industry, nonprofit organizations, and private individuals are already paying off for some areas of the country, the fact remains that the Clean Air Act mandates EPA not to forget Americans who still pay for unhealthy air quality with increased health care costs, lost productivity, lost quality of life and premature deaths. Those costs are perhaps less noticeable in the short term for the individual observer and more difficult to quantify, but they exact a great toll on the US economy as well. "By 2030, EPA air quality emissions standards for vehicles are projected to annually prevent 40,000 premature deaths, 34,000 avoided hospitalizations, 4.8 million work days lost." As reductions in air pollutants are achieved over time, we believe that "the associated air quality benefits will lead to improved health, longevity, and quality of life for all Americans."

   3(d) Effects of Less Frequent Collection

	The CAA states that emission certification must be done on a yearly basis (CAA 206(a)(1)), coinciding with the industry's 'model year.'  Major product changes typically occur at the start of a model year.  For these reasons, a collection frequency of less than a model year is not possible.  However, when an engine design is "carried over" to a subsequent model year, the amount of new information required is substantially reduced. 

	For practical reasons, PLT reports are submitted on a quarterly basis.  Manufacturers are required to test up to one percent of their production at random to ensure that mass produced engines comply with emission requirements.  If a problem is found, manufacturers must correct it and might need to recall engines that have already been sold.  Engine manufacturing companies update their internal production volume reports every quarter.  By conducting this quality control testing also on a quarterly basis, manufacturers are able to learn about and address any problems early, before the start of the next quarter's production, thus minimizing costs.   

	In-use testing and SEA information is collected on occasion, when EPA orders testing of a particular engine or audits a particular manufacturer. 

   AB&T and TPEM data is collected annually, once manufacturers elect to participate in those programs, also to correspond with manufacturing cycles and to make data collection and compliance verification more manageable for both EPA and respondents. 

   
   3(e) General Guidelines

	Certification, ABT, and end-of-the-year report related records must be maintained for eight years. Note that respondents may "store these records in any format and on any media, as long as [respondents] can promptly send us organized, written records in English if we ask for them" [for example in 1039.250(d), 1042.250(d)].  For HD engines, "records may be retained as hard copy or reduced to microfilm, ADP film, etc., depending on the manufacturer's record retention procedure, provided that in every case all the information contained in the hard copy is retained" [(86.000-7(a)(3)].  These recordkeeping requirements stem, in large part, from the statutory requirement to warrant some items for long periods of time.  In addition, the manufacturers must comply with requirements to recall vehicles and engines failing to meet emission standards during their useful lives. However, data related to routine testing such as test cell temperatures and relative humidity readings, must only be kept for one year after a certificate of conformity is issued.  

	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 vehicle or engine to which it pertains is available for purchase.

      For practical reasons, PLT reports are submitted on a quarterly basis.  Manufacturers are required to test a number of engines at random to ensure that mass produced engines comply with emission requirements.  If a problem is found, manufacturers must correct it and might need to recall engines that have already been sold.  Engine manufacturing companies update their internal production volume reports every quarter.  By conducting this quality control testing also on a quarterly basis, manufacturers are able to learn about and address any problems early, before the start of the next quarter's production, thus minimizing costs.   

	Under an SEA, manufacturers are required to submit test results and information within five working days after all engines ordered to be tested have been tested.  The items requested are all readily available or generated during the SEA.  For nonroad engines, a report on the test results must be submitted within 30 days (see Section 1068.450).  The information is requested in less than thirty days so that EPA can verify the accuracy and validity of the emission data and expeditiously reach a conclusive audit decision.  An expeditious audit decision allows the manufacturer to quickly release the tested vehicles or engines for introduction into commerce.

	No other general guideline is exceeded by this information collection.

   3(f) Confidentiality

	Manufacturers are allowed to assert a claim of confidentiality over information provided to EPA.  Confidentiality is provided in accordance with the Freedom of Information Act and EPA regulations at 40 CFR Part 2.  For further detail, refer to section 3(e).
   
   3(g) Sensitive Questions

	No sensitive questions are asked in this information collection. 

4.  Respondents and Information Requested

   4(a) Respondents/SIC Codes

	Respondents are manufacturers of heavy-duty and non-road engines, vehicles and equipment within various North American Industry Classification System (NAICS) codes. Respondents to NRCI, locomotive, and marine CI requirements fall in the following categories:

   4(b) Information Requested

	This section summarizes the various programs included in this collection and their reporting and recordkeeping requirements as well as the tools used to collect that information. It includes many regulatory references or citations. When a requirement is found in multiple regulations covered in this request, we provide several of the citations. Please note that in those cases, the list of citations is not meant to be exhaustive. 

      This information collection implements a three-stage process envisioned in the Clean Air Act with regards emissions from mobile sources: engines, vehicles and equipment. The three-stage process starts with the certification program, where EPA issues certificates of conformity to those engines/vehicles that meet emissions requirements. Programs such as AB&T provide manufacturers with flexibility to meet those requirements. To apply for a certificate, manufacturers must describe prototypes of their products and supply test data to demonstrate compliance with applicable standards.  This information is organized by engine or vehicle groups called "families" and by model year. Engines or vehicles that are subject to multiple regulations may need to obtain more than one certificate.
      
      Obtaining a certificate of conformity, however, is not the end of the road; but the beginning. The Clean Air Act requires EPA to verify that the manufacturer successfully translated their prototypes into mass-produced engines or vehicles and that those engines/vehicles comply with standards throughout their useful life. Programs such as Production Line Testing (PLT), In-use Testing and Selective Enforcement Audits (SEAs) accomplish that as described in this section. Not all programs apply to all industries and specific requirements vary depending on the characteristics of each engine/vehicle family.
      
	Most of the information in this request is collected electronically through EPA's Engines and Vehicles Compliance Information System (EV-CIS), formerly known as VERIFY, as described in Section 5(b) of this document. EV-CIS has different components or modules to house and manage the data. Certification and defects data is collected using webforms (screens). TPEM, AB&T and other compliance programs data is collected through Excel-based templates that are then uploaded into the Compliance Database. Table 4 below provides a list of forms used in this collection which are  available at https://www.epa.gov/vehicle-and-engine-certification/certification-and-compliance-nonroad-vehicles-and-engines.

      Reporting and recordkeeping requirements vary according to the characteristics of the engine/vehicle being certified and the programs manufacturers elect to participate in. However, the data requested and recordkeeping timelines are very similar across industries. Some of the data items are only required to be kept in records and submitted upon request. 	

      EPA may deny an application, revoke, suspend or void a certificate for an engine family for which the manufacturer [1039.255(c) and 1042.255(c), 1068.601]:
 Refuses to comply with any testing or reporting requirement
 Submits false or incomplete information
 Submits inaccurate test data
 Fails to update an application to include all engine models being produced,
 Fails to supply information requested by the agency
 Fails to keep records or does not produce them when asked by EPA
      
	Should EPA deny or revoke a certificate, the affected manufacturer may request a hearing within 30 days of the EPA's decision. The request must be in writing, include a description of the manufacturer's objections and data to support the objections.  Hearings will be conducted using the procedures specified in 40 CFR Part 1068, Subpart G. 


      (4)(b)(i)  Data Items
	
		(4)(b)(i)(1) Pre-model year reports  -  HD GHG Engines and Vehicles Only

	NHTSA's regulations at 49 CFR 535.8(b) require manufacturers of HD pickups and vans subject to fuel economy standards to provide pre-model year reports prior to submitting their first application for certification. The information can be submitted during a voluntary annual certification preview meeting with EPA and NHTSA. Pre-model year reports providing "early estimates demonstrating how [a manufacturer's] fleet(s) would comply with GHG emissions and fuel consumption standards." The information is needed to help construct an annual testing plan. Each pre-model report must include the following:
 Make and model designations and attribute-based values of each unique vehicle subconfiguration in the manufacturer's fleet
 Emission and fuel consumption fleet average for each configuration
 Estimated production volumes by vehicle configuration, test group and fleet
 Expected emissions and fuel consumption test results and fleet average performance
 The list of Class 2b-3 cab-complete vehicles and the method used to certify them
 The list of Class 4 and 5 incomplete and complete vehicles and the method used to certify them
 List of loose engines included in the heavy-duty pickup and van category and the list of vehicles used to derive target standards
 Copy of any notices sent to the engine manufacturer about using their compliant engines in excluded vehicles
 An AB&T plan including plans to resolve any credit deficit that may occur. AB&T is described in section (4)(b)(i)(3) below.


		(4)(b)(i)(2) Certification  -  All Industries
       
      To apply for a certificate, manufacturers must describe prototypes of their products and supply test data to demonstrate compliance with applicable standards.  This information is organized by "engine or vehicle family." An engine or vehicle family is a group of engines/vehicles expected to have similar emission characteristics. Specific criteria for establishing these families, sometimes referred to as test groups, is outlined in each industry's standard setting part. For example, for HD GHG engines and vehicles, the criteria are found in §1036.230 (engines) and §1037.230 (vehicles). Vehicle families may be further subdivided in sub-families and configurations. Each manufacturer identifies the worst-case scenario among its families and test groups and selects them for actual testing. 
      
      Certificates are issued on a "model year" (MY) basis. A model year refers to the manufacturers' annual production period, or a calendar year if the manufacturer does not have a model year. Engine families need to be certified each model year. Manufacturers must indicate whether they are applying for a "50-state" certificate, a "49-state" certificate (engines/vehicles are don't comply with California's emissions requirements) or a "California-only" certificate (for engine families that are to be sold only in California). 
      
	In some industries, there are more than one type of manufacturer. For example, in the locomotive industry manufacturers of locomotives, locomotive engines and locomotive remanufacturers must obtain certificates of conformity with emission standards. As appropriate, we've highlighted the most important differences in reporting and recordkeeping requirements for each category.
      
      Most engine families are only certified for emissions of criteria pollutants such as carbon monoxide, nitrogen oxides, hydrocarbons, and particulate matter. However, certain HD engines, nonroad CI and marine CI engine families that will be fueled with volatile liquid fuels other than conventional diesel must obtain two certificates of conformity: (1) an Exhaust Emissions (criteria pollutants) Certificate under the applicable standard setting part; and (2) an Evaporative Certificate  under Part 1060. Medium- and Heavy-duty engines and vehicles (collectively referred to in this document as HD GHG engines/vehicles) are also subject to fuel consumption and GHG emissions standards for carbon dioxide (CO2), nitrous oxides (N2O), hydrofluorocarbons (HFC) and methane (CH4). Manufacturers of HD GHG engines regulated under Part 1036 obtain (1) a certificate of conformity with GHG emissions requirements, (2) an Exhaust Emissions Certificate under Part 85, and (3) comply with NHTSA's fuel economy requirements. HD GHG Vehicle manufacturers must obtain a HD GHG certificate under Part 1037 and comply with fuel economy requirements.
      
      For Marine CI Category 3 engines, reporting and recordkeeping requirements vary according to its characteristics as well as the vessel in which the engine is installed. Based on those characteristics, engine or vessel manufacturers may need to obtain between one and three certificates of conformity:
 Exhaust Emissions Certificate under 40 CFR 1042  -  all engines sold or installed in vessels that navigate US waters must be covered by a Part 1042 certificate. Must be obtained annually. 
 IMO Certificate  -  demonstrates compliance with international standards, codified for the US at 40 CFR Part 1043.  Required for commercial engines/vessels which travel beyond US territorial waters. Must be obtained at least once.  Recertification is only necessary if the engine design undergoes changes that affect emissions.
 Evaporative Certificate  -  required for engines that will be fueled with volatile liquid fuels other than conventional diesel. Must be obtained annually.
      
      The burden associated with certifying a given engine or vehicle family is usually reduced after the first production year (model year), because certification data and information from previous years can be "carried over" if no significant changes have occurred.  For instance, an engine family certified in MY 2018 can be certified in MY 2019 and subsequent years by "carrying over" the test data used in the 2018 application if no significant emissions-related changes have occurred to the engine family between model years. EPA may also allow manufacturers to "carry across" data from HD certification to NRCI certification and vice-versa for engine families they produce for both markets if there are no significant differences between the HD and NRCI versions of the engine family.  Allowing manufacturers to "carry over" and "carry across" data saves manufacturers the cost of testing both families.  
      
      Manufacturers may make changes to one or more engine/vehicle models within a family at any time during the model year (`running changes').  These running changes may significantly affect the engine models, and therefore, the engine family's emission levels.  For this reason, all engine emissions compliance programs run on a model year basis.  
      
	Engine manufacturers must label all engines. The label must identify each engine and state the engine family name, the fuel(s) the engine is certified to run on, the engine useful life and category, if applicable. Other language applies if the engine is being certified under a special provision or exempted under any of the programs discussed here. Under certain circumstances, nonroad equipment or vessels must also be labeled. Manufacturers are also required to provide warranties and owner's manuals to consumers.  
 
	An application fee must be paid per engine family per model year.  This fee, which is recalculated every year, is requested under the authority of Section 217 of the CAA and the Independent Offices Appropriation Act (31 U.S.C. 9701) to ensure that the motor vehicle emissions compliance program is self-sustaining to the extent possible.  Fees are collected electronically at www.pay.gov or by mail using the Nonroad Fee Filing Form, Form 3520-29.  The fee filing form is covered under ICR 2080.05, OMB Control Number 2060-0545. Additional information is available at https://www.epa.gov/vehicle-and-engine-certification/fees-information-motor-vehicle-and-engine-compliance-program-mvecp and in section 6(b)(ii) of this supporting statement. 

	The following is a summary of data items requested for certification-related activities and recordkeeping.  Other data items may be listed in the regulations.  EPA regulations provide that the Agency may also require additional information as needed to evaluate the application for certification and determine compliance with various requirements.

Routine emission records must be kept for only one year [1036.250(c) and 1037.250(c)].
 
                  (4)(b)(i)(2)(A) HD GHG Engine & Vehicle Manufacturers

   Manufacturers that must comply with HD GHG and fuel economy requirements have additional certification data requirements found at 1036.205 and 1037.205. In general terms, the requested data items provide a complete description of the engine/vehicle family to be certified, its emissions profile and methods used/requested for demonstrating compliance, whether the engine/vehicle family is participating in ABT, etc. Some items are unique to certain types of engines or vehicles. GHG and fuel economy data is collected through EV-CIS and shared. Some respondents may elect to submit some fuel economy data through NHTSA's CAFÉ database or in writing [535.8(a)(6)]. 
   
   Under 1036.210, 1037.210 and 1037.211, manufacturers may seek a preliminary approval or determination by submitting a draft application. They may also amend their applications, even after a certificate has been issued, to include new or modified engine configurations and for other reasons (1036.225 and 1037.225).

                  (4)(b)(i)(2)(B) Rebuilders & Aftermarket Part Manufacturers

       Manufacturers or rebuilders of aftermarket engine parts for nonroad CI engines are not required to apply for certificates of conformity, but must keep information that shows how their parts or service affect emissions.  EPA may test engines and equipment to investigate potential defeat devices or may require the manufacturer to complete this testing.  Manufacturers may need to provide information regarding test programs, engineering evaluations, design specifications, calibrations, on-board computer algorithms, and design strategies.  (see Section 1068.110) 
 
      The following records must be kept for at least two years after rebuilding an engine, and must be accessible for EPA's review.  Records may be based on engine families rather than individual engines if that is a normal business practice.
   ●	Hours of operation (or mileage, as appropriate) at the time of the rebuild
   ●	Work completed on the engine or any emission-related control components, including a listing of parts and components used
   ●	Engine parameter adjustments
   ●	Emission-related codes or signals responded to and rests
			
					(4)(b)(i)(2)(C) Alternative Fuel Converters

      Aftermarket fuel conversion systems allow gasoline or diesel vehicles to operate on alternative fuels such as natural gas, propane, alcohol, or electricity. Use of clean alternative fuels opens new fuel supply choices and can help consumers address concerns about fuel costs, energy security, and emissions. EPA is responsible for ensuring that all vehicles and engines sold in the United States, including aftermarket conversions, meet emission standards. Regulations pertaining to alternative fuel conversions are codified at 40 CFR Part 85, Subpart F. Engines can be converted when they are new or nearly new (beginning of useful life), sometime between the second year of use and the end of their useful life (intermediate age) or after their intended useful lives has ended (outside of useful life).

      Alternative fuel converters must obtain certificates of conformity with emission standards. However, the amount of information collected from beginning-of-useful-life converters is reduced as converters may group multiple engine families into a larger one. Engine families must share certain characteristics before they can be combined. Converters of new engines submit their certification applications through EC-VIS in the same manner as other HD engine manufacturers. They must also comply with HD GHG requirements and evaporative requirements, as applicable. Those programs are addressed in earlier in this section.
      
      The burden for converters of intermediate age engines is even lower. Instead of testing their converted engines, they can submit a simplified On-Board Diagnostics testing demonstration instead of a full certification application. Converters of engines outside their useful life also benefit from a reduced burden.  Converters can simply submit an On-Board Diagnostics (OBD) scan tool test report and a detailed technical description of the conversion system sufficient in detail for EPA to confirm the conversion system's ability to maintain or improve on emission levels in the converted engine. EPA has developed Forms 5900-338 and 5900-259 for converters of intermediate age and outside-of-useful-life engines use EPA, respectively, to submit their applications. 
      
Summary of data items:  

      For all engine conversions: 
       Expanded conversion engine families 
       New engine label requirement describing OEM engine family, mileage, and date 
   
      For intermediate-age and outside useful-life age vehicles (25%):
       Online notification and test result report rather than application for certification 
       A engineering judgement "demonstration" for intermediate age  and outside useful life conversions
       OBD scan tool report showing results of an OBD scan tool test procedure 
       A statement that the OBD system remains fully functional in the converted engine.
       Intermediate age and outside useful life engine families will not be required to pay a certification fee.

                   (4)(b)(i)(2)(D) Confirmatory Testing
       
	From time to time, EPA may conduct confirmatory testing. When there is reason to believe that a compliance issue may exist with the emissions data submitted at certification, EPA may, at its own expense, purchase or rent engines/vehicles and test them.  Manufacturers may be notified about this testing in advance and may be required to explain discrepancies found between EPA test data and data submitted by the manufacturer.

		(4)(b)(i)(3) Production Reports

      Most manufacturers must submit an Annual Production Report identifying the number of engines or vehicles produced by engine family, by gross power, by displacement, by fuel system, or by other categories. For all industries except HD GHG engines and vehicles, the report is due within 45 days after the end of the model year and must be submitted using Form 5900-90. The data is then electronically uploaded into the Compliance Database. HD GHG manufacturers' deadline is 90 days after the end of the model year. Production is reported by serial number/vehicle identification number and engine/vehicle configuration. Vehicle manufacturers must include subfamily identifiers and must report uncertified vehicles sold to secondary vehicle manufacturers. We may waive this requirement for small engine manufacturers, while small vehicle manufacturers may omit this requirement altogether. Engine manufacturers may combine this report with their AB&T reports. HD GHG reports are submitted directly to EC-VIS' HD GHG module.

 
		(4)(b)(i)(4) Averaging, Banking and Trading (AB&T)
 
 AB&T is a tool allow HD engine and vehicle manufacturers to introduce into the US market engines that emit above emissions limits provided other cleaner engines compensate for the additional emissions. Engine manufacturers may earn positive credits for engine families that emit below an established family emissions limit and then use those credits to obtain certification for engine families that emit above the limits. The overall credit balance, also called `average', is calculated based on credit generation/usage by engine family and how many units of each engine model were sold during the year. That average must be zero or above at the end of the year, meaning that the participant's overall production meets or exceeds the emissions limits. Credits may be banked for use in subsequent years or traded among participants. Credits must be calculated by pollutant and by type of engine and vehicle, among other criteria. Participation in AB&T is voluntary. 
 
 Participants must indicate in each engine family's certification application whether that family is participating in AB&T. Then, the following year, they must submit two reports which include all the participating engine families: an end-of-the-year report (draft report due by March 31) and a final report (due by September 30).  AB&T reports provide data on the number of credits used or generated by each engine family; and verify that participants have a zero or above credit balance at the end of each model year. Manufacturers have 270 days after the end of the model year to correct any mistakes found in the credit balance calculations. If the initial report shows a negative balance, EPA may disallow the correction [(1036.730(f)(2), 1037.730(f)(2), etc.]. If credits are sold or purchased, a trade report must be submitted within 90 days of the transaction [(1036.730(d) and 1037.730(d)].
 
      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 ABT programs. They cannot, however, use credits generated under one program to satisfy the requirements of the other.  Credits can only be generated for NOx 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.

		(4)(b)(i)(5) Production-Line Testing (PLT) and Product Verification

	Of the industries covered under this ICR, only Marine CI engines, evaporative families and locomotives are subject to PLT or similar programs. PLT requires engine manufacturers to test a sample of production engines to ensure that they in fact have the same emissions profile as the prototype tested for certification.

				(4)(b)(i)(5)(A) Marine CI PLT

	Under Part 1042, marine CI engine manufacturers must test "one engine or one percent of the projected US-directed production volume for all their Category 1 or Category 2 engine families" [1042.310(a)(1) and (2)]. Manufacturers may request a reduced rate for carryover engines families which have consistently passed PLT testing on each of the preceding two years. Small volume manufacturers and engine families with projected productions of less than 100 units may be exempted from PLT [1042.301 (a)(1) and (2)].

      For category 1 and 2 engines, PLT testing is conducted quarterly, and respondents must report their PLT results within 45 days after the end of each quarter (1042.345(a)). Every Category 3 engine must be tested for NOx emissions either at its vessel's sea trial or within the first 300 hours of operation, whichever comes first.  This is due to the low volume of Category 3 engine families (most consist of between one and four engines). If an engine fails PLT or the manufacturer fails to comply with reporting requirements, EPA may revoke or suspend that engine family's certificate [1042.301(b), 1042.302(a)]. Manufacturers may request alternative testing methods for PLT under 1042.301(d)(3) or 1042.302(e).	

      EPA may audit engine manufacturers' PLT testing procedures. During an audit, manufacturers are required to allow EPA officials to enter into facilities where engines are being manufactured, stored, or tested and where records may be located.  Manufacturers are also expected to afford reasonable assistance (such as clerical or translation services, photocopying, etc.) to EPA personnel conducting the audit.  PLT audit failures and hearing requests are handled in the same manner as SEAs failures and hearings. 
 	
       Information requested under the PLT testing program consists mainly of test results, a description of the engines tested and the conditions under which the tests took place. PLT Reports are submitted electronically using Forms 5900-297 (CumSum) or Form 5900-298 (non-CumSum). Records must be kept for 8 years [1042.350(b)].
 
				(4)(b)(i)(5)(B) Evaporative Family Product Verification
 
      Evaporative families are subject to Product Verification under Part 1060, Subpart D.  Manufacturers are required to use good engineering judgement to verify compliance, which may include testing. While there are no reporting requirements, manufacturers must make the information available [1060.301(b)] and provide samples for testing (1060.310) upon request from EPA. 
      
				(4)(b)(i)(5)(C) Locomotive PLT
      
	Only manufacturers of freshly manufactured locomotive engines are subject to PLT testing requirements.  Remanufacturers, however, must conduct audits under 1033.335. However, if EPA has reason to believe that there are problems with a remanufacturer's production, the Agency can extend PLT testing requirement to that remanufacturer. 

      Under PLT, each calendar quarter, manufacturers must conduct testing on a sample of locomotives or locomotive engines taken directly from the assembly line.  The required sample size for an engine family (as long as there are no failures), is the lesser of 5 tests per year or one percent of the projected annual production [1033.310(b)].  Two additional tests must be performed for each failed test. Respondents may request a reduction in sample size for carry-over families that have successfully completed PLT in the two previous years.  Some engine families may not have production in some quarters or the sample size may be reached before the end of the year, so some respondents may submit less than four reports per engine family per year.

	Per 1033.320(e), within 45 days of the end of each quarter, manufacturers must report the information listed below using form 5900-135.  Locomotive PLT reports are submitted using the PLT Report for Locomotives, EPA Form Number 5900-135. 

   Records, also listed below, must be kept for eight years after completion of all testing [1033.325(b)].  Under 1033.325(d), EPA may require manufacturers and remanufacturers to submit or retain additional information not specifically listed here.  
 The location and description of the test facilities where testing was conducted.
 Total production and sample size for each engine family.
 Applicable standards and/or FELs.
 A description of the test locomotives or locomotive engines.
   
   For each test conducted:  
 Description of the test locomotive or locomotive engine, including engine family and configuration, year, make, built date, engine ID number, etc.; 
 Location(s) where service accumulation was conducted and description of accumulation procedure and schedule, if applicable; 
 Test number, date, test procedure used, initial test results before and after rounding, final test results, etc.; 
 Complete description of any adjustment, modification, repair, preparation, maintenance, and testing which was performed on the test locomotive or locomotive engine; and 
 Any other information the Administrator may request.
 For each failed locomotive or locomotive engine, a description of the remedy and test results for all retests.
 The date of the end of the locomotive or locomotive engine manufacturer's model year production for each engine family tested.
 A statement of compliance, found at 1033.320(e)(7) signed and endorsement by an authorized representative of the manufacturer or remanufacturer.
 Upon request, manufacturers must also submit:  
 Projected production for each configuration within each engine family for which certification has been requested and/or approved; and/or 
 Number of locomotives or engines, by configuration and assembly plant, scheduled for production.


Recordkeeping requirements for the PLT Program:
 
 A description of all testing equipment used or can be used for PLT
 For each PLT conducted: date, time, and location of each test or audit.
 The method by which the green engine factor was calculated or the number of hours of service accumulated 
 The names of all supervisory personnel involved
 A record and description of any adjustment, repair, preparation or modification performed on test locomotives or locomotive engines
 Shipping information including dates and locations, if applicable
 A complete record of all emission tests or audits performed (except tests performed directly by EPA)
 A brief description of any significant events during testing not otherwise described, including engine damage during shipment.
 


                  (4)(b)(i)(5)(C)(i) Remanufacturer Installation Audit Program

      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 45 days of the end of each quarter, remanufacturers must report the following information [1033.335(g)] using the Locomotive Installation Audit Report, EPA Form Number 5900-273: 
 The location and description of the test facilities where the audit was conducted.
 Total production and sample size for each engine family.
 Applicable standards and/or FELs.
 For each audit conducted: A description of the audit locomotive or locomotive engine, including engine family and configuration, year, make, built date, engine ID number, etc., and any other information the Administrator may request.
 For each failed locomotive or locomotive engine, a description of the remedy and test results for all retests.
 A statement found at 1033.335(g)(6) signed and endorsement by an authorized representative of the manufacturer or remanufacturer.

                  (4)(b)(i)(5)(C)(ii) Failed PLT Testing 

	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 nonconformity, retest or re-audit, and submit reports with the following information:

 A description of the remedy and new test or audits results.
 The reason for the failure, the remedies and the date when the remedies will be implemented.
 A demonstration that the failed engine family does in fact conform.
 Manufacturers and remanufacturers may request a hearing.
 Within 30 days, the interested party must file two copies of their written request, which must include:
 A statement as to which configuration(s) within a family is to be the subject of the hearing.
 A concise statement of the issues to be raised by the manufacturer or remanufacturer at the hearing.
 A statement specifying reasons why the manufacturer or remanufacturer believes it will prevail on the merits of each of the issues raised.
 A summary of the evidence which supports the manufacturer's or remanufacturer's position on each of the issues raised.

 
			(4)(b)(i)(6) In-Use Testing 

      The In-use Program seeks to verify that engines comply with emission standards throughout their useful lives, as mandated in the CAA.  There are two types of in-use testing programs: (1) Manufacturer-run testing, where EPA orders engine manufacturers to in-use test at their expense certain engine families; and (2) EPA-run testing where the agency locates and tests engines at its own expense. 
       
				(4)(b)(i)(6)(A) Manufacturer-run In-Use Testing
       
       Of the industries covered by this ICR, this program only applies to locomotives and HD engines/vehicles. Per 40 CFR Part 86, Subsection T, every year EPA issues in-use test orders to a number of manufacturers and engine families.  A minimum of five engines/vehicles per engine family are tested. Once manufacturers have collected test data, locomotive manufacturers submit data using the locomotive in-use template, EPA Form Number 5900-435. HD manufacturers submit data (criteria pollutant only) via EV-CIS.  
 
				(4)(b)(i)(6)(B) EPA-run In-Use Testing
       
      EPA may also run in-use testing programs, at its own expense. For industries under an EPA-run In-use Testing Program, there is no specific requirement for manufacturers to conduct in-use testing, submit information or keep in-use records. However, EPA may perform in-use testing on any marine CI engine (Part 1042, Subpart E), evaporative family (Part 1060, Subpart E) or any HD GHG engine (Part 1036, Subpart E) or vehicle (Part 1037, Subpart E). 
      
      HD engine manufacturers may request that the EPA use a higher FEL for in-use testing, subject to the rules governing FEL changes (1036.625).  This option is not available to HD vehicle manufacturers.

       EPA-run in-use testing programs are conducted at the National Vehicle and Fuel Emissions Laboratory (NVFEL).  Engines or vehicles obtained by EPA for in-use testing purposes are leased from businesses or other government entities which EPA locates through either: (1) potential fleet owners/lessees in registration lists; (2) engine manufacturer-supplied customer lists; and/or (3) existing contacts that have provided EPA with valuable information in the past.  
      
      EPA contracts out most of the work related to finding the necessary vehicles/engines. EPA staff directs a contractor to locate heavy-duty vehicles with specific engine families. The contractor then calls fleet facilities to locate vehicles that meet the criteria and specifications outlined by EPA staff.  Once potential sources are identified and leased for EPA's in-use testing program, EPA staff install a mobile emission measurement equipment. On-road testing is conducted with the contractor assistance onsite at NVFEL. Within a typical year, about 200 vehicles/engines from different industries are leased and tested. Testing for each one of those vehicles/engines lasts about 2 weeks (8 hours per day).  The driving conditions and information gathered may vary depending on the issues relevant to the type of heavy-duty vehicle selected and tested.  After testing, the emissions measurement equipment is removed and the vehicle is returned to the owner.  
      
      While EPA contacts fleet owners to locate vehicles/engines, in most cases there is no communication with the engine/equipment manufacturer unless a compliance issue is found. Since EPA compensates the fleet owners for the use of their vehicles/engines as any other customer would, the activities associated with this program are considered customary business practices. 
      
      
			(4)(b)(i)(7) Selective Enforcement Audits (SEAs)
 
       During an SEA, EPA visits the facilities where a manufacturer's testing is conducted. The primary purpose of a SEAs is to verify that the laboratory's testing methods comply with EPA regulations. Only Nonroad CI, HD engine and HD vehicle manufacturers' laboratories are subject to SEAs. Marine CI engine manufactures are not since they are subject to a robust PLT program.  
       
       EPA collects the information needed for SEAs in two stages:  First, a limited number of manufacturers are asked to submit their production plans for a specified period of time, as described below.  EPA uses this "pre-audit" information to efficiently determine which manufacturers and engine models to audit.  After a manufacturer has been chosen, EPA issues a test order specifying which engine models and configurations will be tested. Testing is then performed on engines coming out of the assembly line under the observation of EPA staff. When all required testing is completed, manufacturers submit a report containing all testing results.  This "audit" information is then used to determine compliance with applicable emission standards.  
 
 	Per 89.505 (d), 86.1005-90(d), and 1068.450, EPA can request manufacturers to submit additional SEA information or keep records not specifically listed in this section.  SEA data requirements can be found at Part 1068 Subpart E for nonroad CI engines and Part 86 Subpart K for HD Engines.
 	
 	Upon EPA's request, engine manufacturers must submit the following information regarding engine production. This information is used by EPA as pre-audit data under the SEA Program to determine which engines will be audited.
   ●	Projected U.S. sales data for each engine configuration and engine family
   ●	Number of engines, by configuration and assembly plant, scheduled for production within the time period designated by EPA
   ●	Number of engines, by configuration and assembly plant, storage facility or port facility, scheduled to be stored during the time period designated by EPA
   ●	Number of engines, by configuration and assembly plant, produced during the designated period that are complete for introduction into commerce

 	Within 30 days after all tests ordered by EPA are completed, manufacturers must submit a report with the following information:
    ●	Testing facilities' location and description
    ●	Applicable standards or compliance levels against which the engines were tested
    ●	Deterioration factors for the selected configurations
    ●	Description of the engine and the method used to select its emission-related components.
 
       For each test conducted:
    ●	Test engine description
    ●	Location where service accumulation was conducted and a description of the procedure
    ●	Test information, raw results, which includes emission figures for all measured pollutants, for both valid and invalid test results
    ●	A complete description of any modification, repair, preparation, maintenance and/or testing performed on the engine not previously reported.  This must include the results of any emission measurements, regardless of the procedure or type of equipment
    ●	If an engine was deleted from the test sequence by authorization of EPA, the reason to delete it
    ●	Brake-specific fuel consumption values for all valid and invalid tests
    ●	Any other information requested by EPA
●	Statement of compliance and endorsement
    ●	For nonroad CI engines, a report on each failed engine
●	Request for re-testing of failed engines, if applicable
    ●	For nonroad CI engines, an authorized representative of the company must sign the statement under Section 1068.450(c) to accompany reports.
 
 Recordkeeping
 
 	Records must be kept for one year after all ordered tests have been completed.  Records may be kept in any media, according to the manufacturer's procedures, provided that in every case all the information contained in the hard copy is kept.  Note that EPA may review manufacturer records at any time.  
 
       General records:  a description of all test equipment used, including the information submitted with the audit report described above.
 
Individual records for each audit:
    ●	If a nonroad CI engine was shipped for testing, the date of shipping, the associated storage or port facility, and the date the engine arrived at the testing facility
●	Date, time and location of each test
●	Any records related to an audit that are not in the written report for nonroad CI engines
    ●	Number of hours accumulated in each engine when testing began
    ●	Names of all supervisory personnel involved
    ●	Detail records of all repairs performed prior/after EPA's authorization
    ●	Date engine was shipped and date it was received
    ●	Complete record of all tests performed including worksheets and other documentation
●	Brief description of any significant event that occurred during the audit
●	For nonroad CI engines, a manufacturer must be able to provide projected or actual production for an engine family, which includes each assembly plant
    ●	Copy of the trace for each test
    ●	Description of the equipment in each test cell that can be used to perform SEA testing

 	During a SEA, manufacturers are required to allow EPA officials to enter into facilities where engines are being manufactured, stored, or tested and where records may be located.  Manufacturers are also expected to afford reasonable assistance (such as clerical or translation services, photocopying, etc.) to EPA personnel conducting the audit. When an engine family fails an audit, the certificate of conformity issued to that engine family may be revoked or suspended, in whole or in part, effective no later than 10 days after failure. A certificate may be suspended for other reasons including refusal by the engine manufacturer to allow EPA to gain access to the appropriate facilities.  The affected manufacturer must then remedy the nonconformity, retest or re-audit.  In any of these cases, the affected manufacturer must submit a report describing the reason for the noncompliance and the remedy to be implemented, among other items appropriate to each case.  Section 86.1012 explains revocation of certificates for heavy-duty, on-highway engines.  Section 1068.445 includes the corresponding provisions for NRCI engines.
 
 	If the affected manufacturer disagrees with EPA's determination to revoke a certificate of conformity, the manufacturer may request a public hearing.  Under the SEA Program and the Marine CI PLT Audit Program, a request for public hearing must be filed within 15 days after the revocation and must include the following information.
    ●	Statement regarding which configuration(s) within a family is to be the subject of the hearing
    ●	Concise statement of the issues to be raised by the manufacturer at the hearing
    ●	Statement specifying reasons why the manufacturer believes it will prevail on the merits of each of the issues raised
    ●	Summary of the evidence which supports the manufacturer's position on each of the issues raised
 
		
		(4)(b)(i)(8) Defects and Recalls
       
       All certificate holders "must investigate in certain circumstances whether engines/equipment that have been introduced into U.S. commerce under your certificate have incorrect, improperly installed, or otherwise defective emission-related components or systems. This includes defects in design, materials, or workmanship" (1068.501).  Part 1068, Subpart F describes the process applicable to most certified engines/vehicles/equipment. For older engines/vehicles/equipment, a similar but slightly different process may apply under the applicable standard setting part.
      
      Manufacturers of defect HD engines used to submit their defects and recall reports under Part 85, Subparts S and T using the following Adobe Reader-based forms:
 Form 590-301  -  HD Defect Information Reports
 Form 590-300  -  HD Voluntary Emissions Recall Reports VERRs, and
 Form 590-302  -  HD VER Quarterly Reports

      However, EPA recently created a module within EV-CIS were manufacturers can submit the data using webforms (screens) or XML files in the same way as they submit their applications for certification. Therefore, the Adobe-Reader forms are no longer in use. Since the system is new and some manufacturers may still need/want to use the forms, we are not requesting discontinuing these forms just yet.
 	
 Investigation Reports 
 
       Manufacturers are required to start an investigation when their data indicates that an emission-related defect may exist in a substantial number of properly maintain engines. If the number of engines/equipment that have a possible defect reach a threshold specified in Section1068.501(e), the manufacturer must investigate. The thresholds are based on the family's projected sales. Under Parts 85-94, the regulations generally trigger defect reporting requirement at 25 engines or more (10 for locomotives), and do not regulate the investigation phase.  
 
 	During the investigation phase, manufacturers must submit mid-year (by June 30) and end-of-year (by December 31) reports to describe the methods used and the status of the investigation. The reports must explain progress made and conclusions reached, including:
 Description of the defect and the engines that have it
 Estimates of the number or percentage of affected engines/equipment per class or category
 Estimate of the defect's impact on emissions
 A plan for addressing the defect or an explanation of the reasons that the defect does not need to be addressed
 
 
 Defect Information Reports (DIRs)
 
       If the investigation shows that the number of defective engines/equipment in fact meet the threshold, the manufacturer most submit a Defect Information Report (DIR) within 21 days after learning that the threshold has been met. (Under Parts 85-94, the deadline is usually 15 working days.)  These requirements apply only to engines that have already been sold to the public and remain in effect for five years after the model year in which the engine was certified. For engines subject to Part 1068, the requirements apply for the entire useful life of the engine or five years after the end of the model year, whichever is longer [40 CFR 1068.501(b)(4)]. 
 
       Data items requested in Defect Information Reports include:
 The manufacturer's corporate name
 A description of the defect
 A description of the class or category of engines
 Number of vehicle or engines estimated or known to have the defect and explanation of derivation.
 The address of the plant(s) where they were produced
 Evaluation of the emissions impact and any driveability problems it might cause
 Available emissions data related to the defect
 Indication of any anticipated manufacturer follow-up
 
 Recalls and Voluntary Recalls
 
       After a manufacturer determines that the applicable threshold was met, the manufacturer may choose to recall the engines or EPA may order a recall. (For simplicity, we are referring to all recall reports as VERRs, a widely used name, regardless of whether the recall was voluntary or mandated.)  Under Part 1068.505(c), manufacturers have 60 days to submit a remedial plan (VERR). 
 For other industries, if the recall involves 25 engines or more (one for locomotives), they must notify EPA about the recall within 15 days of the date they first started to notify engine owners.
 
       Information items requested in VERRs include:
 A description of the class or category of engines being recalled 
 A description of the modifications or repairs made to correct the defects
 A description of the method being used to identify and contact the owners
 A description of any conditions for eligibility for repair and any reasons for the conditions
 A description of the procedure to be followed by the owner to obtain repairs and where the repairs can be obtained
 If repairs are not being performed at dealers, a description of who will perform the repairs and where the defect will be remedied
 Copies of the letters of notification to be sent to the vehicle owners
 A description of the system for assuring an adequate supply of parts is available for the repairs and that they are performed in a timely manner.
 Copies of all necessary instructions to be sent to the persons who are to perform the repairs
 A description of the impact of the proposed changes on fuel consumption, drivability, and safety of the engines 
 A sample of any labels to be applied to the participant engines identifying the recall being performed
 
 
 Recall Progress Reports 
 	
 	VERR Quarterly Progress Reports (VERR updates) document the progress of voluntary (or mandated) recalls.  Manufacturers must submit VERR updates for six consecutive quarters following the beginning of any recall campaign, or until all engines have been inspected, whichever comes first (Part 85.1904(b), Part 92.404(b) & Part 1068.525(b)).  These reports must be submitted no later than 25 working days after the end of each calendar quarter.
 
 For all industries, VERR updates generally include:
 Recall campaign number
 Date of owner notification and completion
 Number of engines known or estimated to be affected by the defect
 Number of or engines brought in and inspected as part of the campaign
 Number of engines found to have the defect after inspection
 Number of engines actually receiving repair
 Number of engines determined to be unavailable due to exportation, theft, scrapping or other reasons
 Number of engines determined to be ineligible because of improper maintenance or use
 Copies of any service bulletins sent to dealers which relate to the defect that had not previously been reported
 Copies of all communications transmitted to vehicle owners which relate to the defect to be corrected not previously submitted
 Revisions to any of the information previously submitted
 Vehicle owner contact information upon request
 
 Defects & Recalls Recordkeeping Requirements
 
 	Defect and recall records must be kept for at least five years after the last report was submitted. Locomotive and locomotive engine manufacturers under Part 92 however, must keep these records for eight years.  Records may be kept in any format, as long as they are readily available and EPA can inspect them:
 A paper copy of written reports
 The names and addresses of vehicle or engine owners who were notified\
 For every engine or piece of equipment state whether it was inspected, disqualified or repaired
 
 
			(4)(b)(i)(9) Transition Program for Equipment Manufacturers (TPEM)
   
      When EPA establishes new regulations with tighter engine emission standards, engine manufacturers often need to change the design of their engines to achieve the emissions reductions required by the new standards.  Consequently, equipment manufacturers may also need to redesign their products to accommodate these engine design changes. Sometimes, equipment manufacturers, many of whom are small businesses, have trouble making the necessary adjustments by the effective date of the regulations. To provide equipment manufacturers with some flexibility in complying with the regulations, EPA created the Transition Program for Equipment Manufacturers (TPEM).  Under the program, equipment manufacturers may delay compliance with the new standards for up to seven years as long as they comply with certain limitations. Participation in the program is voluntary.  Participating equipment manufacturers and engine manufacturers who provide the noncompliant engines are required to keep records and submit reports of their activities under the program.  
      TPEM, which is currently in its final phases, is available only to NRCI equipment manufacturers under 1039.625 and 1039.626. TPEM consists of two "allowances": The Percent-of-Production Allowance and the Small Volume Allowance. Equipment manufacturers can claim only allowance one per power category for the life of the program.  Equipment manufacturers must demonstrate compliance with the provisions of the allowance they have selected for each power category by submitting the corresponding calculations and by keeping adequate records of all exempt equipment using the following forms:
 TPEM Equipment Manufacturer Notification, Form number 5900-242
 TPEM Equipment Manufacturer Report, Form number 5900-240
      
      Importers may bring into US commerce equipment produced under a foreign manufacturer's allowance under the provisions of 1039.626(b). A TPEM importer may import equipment from different foreign equipment manufacturers but must make sure that each piece of equipment is eligible for TPEM (produced under a valid allowance) and for importation. Importers must also submit a notification and annual reports to the EPA.
 TPEM Importer Notification, Form number In Progress
 TPEM Importer Report, Form number In Progress
 Statement to Comply - Form number In Progress

      Equipment manufacturers participating in TPEM must also provide the engine manufacturer supplying the noncompliant engines with written assurance that the noncompliant engines are going to be used under TPEM.  Engine manufacturers need that written assurance to protect themselves against the liabilities found in 1039.101(a)(1) and 1068.101(a)(1). There are also engine labeling requirements under Part 1039. Engine manufacturers must report annually the number of engines sold under the program using the TPEM Engine Manufacturer Report Form, number 5900-241.

	For imported TPEM equipment, equipment manufacturers or importers may need to post a bond "to cover any potential enforcement actions under the CAA" (1039.626(a)(9)).  NRCI engine manufacturers who also manufacture equipment abroad may request a bond waiver if their US assets exceed $10 million (1039.626(a)(9)(ii)(B)). EPA has developed a simple worksheet that importers can use to calculate the amount of the bond or apply for a bond waiver: TPEM Bond Worksheet, Form number 5900-239.

Data Items Requested from Equipment Manufacturers:

 Letter to the engine manufacturer
 Annual calculation to verify compliance

Data Items Requested from Engine Manufacturers
                                       
      Every year, within 30 days of the end of the model year, engine manufacturers supplying noncompliant engines under the provisions of TPEM must report the number of engines produced by: engine model, purchaser or shipping destination, or other categories that EPA may require. 
      
Recordkeeping Requirements
                                       
      Equipment manufacturers must keep records of all exempt equipment sufficient to demonstrate compliance for at least five full years after the final year in which allowances are available for each power category (1039.625(h)).  These records must be made available to EPA upon request.
 Equipment and engine model numbers [1039.625(h)(1)]
 Serial numbers
 Dates of manufacture
 Engine rated power
 Sufficient information to verify compliance [1039.625(g)]
			
Hardship Relief Requests

      TPEM participants facing economic or technical hardship may request hardship relief as described below. There are two types of hardship relief available to equipment manufacturers: economic (1039.635 & 1068.250) and technical (1039.625(m)). Engine manufacturers have the option, outside of TPEM, of applying for hardship relief when facing "unusual circumstances" (1068.245); however, EPA has received no such request in the last few years. Time limits exist on hardship relief availability.

      Hardship relief is given on a case-by-cases basis. When applying for hardship, manufacturers must submit information in writing about the circumstances that created the hardship, demonstrate that these circumstances are beyond their control and not their fault and, depending on the type of hardship requested, technical and/or financial information. 

Summary of data requested:
   
   Economic hardship relief
 Evidence showing that the conditions causing the impending violation are substantially not the applicant's fault 
 Evidence showing that, if relief is not granted, the applicant will face serious economic hardship 
 Demonstration that no other allowance will help to avoid the impending violation 
 Number of engines or components involved
 The size of the company and its ability to endure hardship
 The amount of time the company had to redesign the equipment and accommodate complying products
 Breach of contracts by suppliers

   Technical Hardship
 A description of the equipment designing process
 A description of the cooperation process with the engine supplier
 A description of the engineering problems causing the technical hardship and the steps taken to address them
 Other relevant information

   Hardship due to Unusual Circumstances
 A demonstration that the manufacturer meets the conditions established in 1068.255(a)
 Unusual circumstances beyond the applicant's control prevent them from complying with current regulations
 Prudent planning was exercised & no other allowances would help
 Not receiving hardship relief would jeopardize the solvency of the company
 A plan showing that how the company will meet applicable requirements as soon as possible
 Other information EPA may request
 There are labeling requirements


			(4)(b)(i)(10) Special Compliance Provisions

      Some provisions address special or unusual situations. These provisions are generally found at Part 1039 Subpart G, 1042 Subpart G, and/or Part 1068 Subparts C & D.  For example, EPA regulations afford respondents the opportunity to exempt their products (avoid certification) when the engines are to be used in certain circumstances, such as:
       National Security Exemptions (NSEs, 1042.635, 1068.225)  -  Agencies of the US Federal Government related to national defense may exempt engines without request if the engines are used in armored and/or specialized vessels. Engine manufacturers may request a NSE if it is endorsed by a defense-related Federal Agency.	
       Testing Exemptions for engines to be used in research, investigations, demonstrations or training	
       Engines used for display only 
       Manufacturer-owned engines
       Emergency applications
       Branded engines
       Competition engines, among others

       Some of these exemptions do not require any reporting, but most require labeling and recordkeeping. With very few exceptions, engines exempted under any of these provisions must not be made available for sale in the US. To request an exemption, the requester submits a letter explaining why they need the exemption and, upon approval, must label the exempted engines accordingly.

      Under certain circumstances, an engine manufacturer may ask EPA to allow the use of a replacement engines.  A replacement engine is a newly manufactured engine that complies with the standards in effect at the time the engine being replaced was built. A replacement engine may only be used if the engine manufacturer determines that no engine certified to current standards, regardless of who manufactures it, is suitable to repower the vessel. Manufacturers who build replacement engines must notify EPA using EPA Form 6900-5414, keep records and label the engines accordingly.
 
    When an engine undergoes a major overhaul, or is `rebuilt,' the rebuilder must keep certain records for two years and make them available to EPA if the agency asks for them (1068.120(k)). The records may be kept on an engine family basis, as opposed to a per engine basis, if that is more consistent with the business' practices (1068.120(3)).  The records must include (1068.120(j)):
 The number of hours of operation or mileage at the time of rebuild. 
 The work done on the engine and/or emissions components
 A description of any engine parameters adjustments
 A list of any emission-related codes or signals that the rebuilder responded to.
 
 	Section 1042.660 establishes reporting and recordkeeping requirements for owners and operators of marine CI vessels. EPA, however, has decided not to implement those requirements. The agency does not collect or solicit these reports and has no plans to implement this reporting requirement in the next three years. 
 
      HD GHG manufacturers may request credit for the use of Innovative Technologies which reduce CO2 emissions (Part 1036.610 and 1037.610). Interested manufacturers must submit a request with the following information:
 Detailed description of the technology
 Proposed test plan
 A recommendation as to how to use the application of this provisions (the improvement-factor method or the separate credit method)
 EPA may require a letter from the engine manufacturer if they can also claim credits for the same technology
 EPA may seek public comments on the request
 
   	Manufacturers from all industries may need to submit information when involved in an enforcement case. The information needed in an enforcement case, most of which has been described in this ICR and included in recordkeeping requirements, varies according to the characteristics of each case. Part 1068, Subpart B provides a list of prohibited acts, a description of potential violations and the different actions the US government may take if a respondent is found in violation of the regulations.
      
 
 	4(b)(ii) Respondent Activities
 
 	In general terms, the activities respondents carry out under the programs included in this collection are similar. As applicable, respondents:
 
 Review the regulations and guidance documents
 Prepare and submit pre-model year reports or related production data for certification applications (HD GHG)
 Develop engine or vehicle "test" or "family" groups
 Test engines and vehicles for compliance with emission and fuel consumption standards
 Gather, analyze and submit test results 
 Submit Applications for Certification
 Label certified vehicles
 Prepare and submit carryover applications or running changes
 Prepare compliance plans and reports, as needed
 Monitor production numbers
 Prepare and submit annual production reports and AB&T reports
 Request exemptions and exclusions as needed
 Organize, store and maintain records


 5.  The Information Collected--Agency Activities, Collection Methodology, and Information Management
 
    5(a) Agency Activities
 
 	As part of the implementation of the programs included in this ICR, EPA officials carry out the following activities:
 
 Review and interpret regulations, provide guidance
 Review pre-model reports, evaluate test plans and credit projections
 Meet with respondents as requested
 Review certification applications for completeness and accuracy
 Verify that the correct engines and vehicles have been selected and tested
 Evaluate test and related technical documents
 Determining if "carry over" of data from a previous model year is appropriate or if new testing will be required
 Issue appropriate certificates of conformity 	
 Collect and review the various reports described in this ICR
 Determine compliance with all regulatory programs and provisions 
 Review credit balances under AB&T
 Conduct confirmatory testing and in-use testing
 Monitor compliance, investigate potential violations and refer findings to the appropriate enforcement office
 Store, file and maintain data
 Answer questions from manufacturers, other government agencies, Congress and the public 
 Periodically perform maintenance or enhance certification and compliance databases as needed
 Make data available to the public and maintain public websites 
 Answer FOIA requests, including analyzing and managing requests for confidentiality
 Collaborate with NHTSA on HD GHG, including sharing data and providing access to databases
 Work with other federal agencies, such as Customs or the Justice Department, as needed
 

    5(b) Collection Methodology and Management
 
      All certification and fuel economy data are collected electronically via the Engine and Vehicle Compliance Information System (EV-CIS), EPA's web-based engine and vehicle emissions database formerly known as VERIFY. To use EC-VIS, respondents must request an account and receive a manufacturer code. Respondents may choose to submit the information via webforms (screens) or XML files. XML files are a convenient way of submitting data, as it allows respondents to dump data from their own systems in the XML file and submit the file to EC-VIS. EC-VIS reads the file and stores it in a `Document Module.' It then notifies the assigned EPA certification representative that a certification application has been receives and is pending review. If the application complies with the CAA and applicable regulations, the certification reviewer approves it and issues a certificate of conformity. A similar process applies for HD GHG certification applications and AB&T reports. HD GHG documents are stored in a database within EC-VIS that is shared with NHTSA. Non-confidential portions of all applications for certification are available to the public at https://www.epa.gov/compliance-and-fuel-economy-data/annual-certification-data-vehicles-engines-and-equipment.

	EPA has developed Excel-based templates for most Compliance Programs (AB&T, PLT, and In-use Testing, and Annual Production Reports) and TPEM. Templates for defects and recall reporting are Adobe-based. Please refer to Table 4 in Section 4(b) of this document for a list of all forms used in this collection. There is currently no template for HD Exhaust In-use Testing reports or SEA reports. While respondents may choose a reporting format, most submit electronically. 

      Compliance Reports templates can be downloaded from EPA's website at https://www.epa.gov/vehicle-and-engine-certification/certification-and-compliance-nonroad-vehicles-and-engines. Once completed, engine manufacturers must use their EV-CIS' accounts to upload the templates into Document Module. The reports are then retrieved from the Document Module and uploaded into the Compliance Database for analysis and storage. TPEM notifications, reports and hardship relief applications can be found at https://www.epa.gov/vehicle-and-engine-certification/transition-program-equipment-manufacturers-tpem and submitted via email to TPEM-CI@epa.gov or TPEMHardshipRelief@epa.gov. An EPA contractor receives the forms and uploads them into the TPEM Tracking System, a section of the Compliance Database, where EPA staff analyzes them as needed to ensure compliance with the CAA and applicable regulations.
 
 
    5(c) Small Entity Flexibility
 
 	EPA regulations include many flexibilities designed to address the needs of small businesses. This section discusses some of them. For example, some small HD engine manufacturers may use optional procedures outlined in 40 CFR part 86, subpart A to demonstrate compliance with the exhaust standards and specific emission requirements.  These optional procedures, which reduce the burden associated with durability data requirements, testing, determination of deterioration factors and certification test data, is available to HD alternative fuel converters with US sales of fewer than 10,000 units. Small HD engine manufacturers in general are exempt from some reporting and recordkeeping requirements associated to the certification of evaporative families [86.098-14, 86.098-22(m)].  Also, section 86.1008-2001 provides a reduced SEA testing schedule for heavy-duty engine manufacturers with projected U.S. sales of 30,000 engines or less.
       
	Small businesses are exempt from HD HGH standards and other GHG requirements until 2022. While larger companies started complying with Phase 1 standards in 2011 and are subject to Phase 2 standards starting in 2021, EPA exempted small business from Phase 1 standards altogether and delayed compliance with Phase 2 standards by one year until 2022 [1036.150(c) and 1037.150(d)]. Then, small businesses will also enjoy simplified certification requirements and other flexibilities. For example, under 1036.250, small engine manufacturers may omit the annual production report. Qualifying small manufacturers producing engines that run on any fuel other than gasoline, E85, or diesel fuel may delay complying with every later standard by one model year. 

	Per 1037.150 (d), small HD GHG vehicle manufacturers must submit, every year, a detailed written description of how that manufacturer meets the Small Business Administration's size definitions of small business as described in 13 CFR § 121.201. This description must be submitted before vehicles excluded from the standards in this way can be introduced into commerce. There are also labeling requirements.
 
 	Per 1042.301(a)(1), small volume manufacturers of marine CI engines may be exempt from PLT requirements. Engine families of fewer than 100 units may also be exempt from PLT requirements (1042.301(a)(2)).
 
      Any manufacturer with the following characteristics may be granted a reduction in the certification application fee: (1) the certificate is to be used to sell engines within the United States; and (2) the full fee exceeds 1% of the aggregate projected retail sales price of all vehicles covered by the certificate of conformity.  Although this is a provision available to all manufacturers, it is beneficial to small manufacturers.  Furthermore, EPA does provide avenues to lower costs such as allowing the carry-over of data from one model year to the next and the use of alternative methods to demonstrate compliance.
      
      The Transition Program for Equipment Manufacturers (TPEM; 1039.625) is based on recommendations made by the panel convened for the August 1998 rule under the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA).  TPEM's small volume allowance is intended to address the needs of small businesses with a limited product line.  The percent-of-production allowance requires equipment manufacturers to use certified engines in a portion of their production.  The small volume allowance eliminates that requirement and allows equipment manufacturers to exempt up to 200 pieces of equipment without using certified engines at all. Regulations at 1039.625 (m) and 1068.255 provide additional flexibilities for small volume manufacturers through hardship relief.
 
 	Under other programs included in this ICR, the information being requested is the minimum needed to effectively conduct and maintain integrity of the required certification and enforcement programs.  Further measures to simplify reporting for small businesses do not appear prudent or necessary.
 
    5(d) Collection Schedule
 
 	Collection frequency depends on the program. For certification, engine manufacturers decide when to submit their applications. That schedule is largely determined by the manufacturer's marketing and production plans.  Running changes and corrections are submitted as the need arises.  Production reports are submitted once a year, while AB&T reports are submitted twice a year. PLT reports are submitted quarterly, as manufacturers update their own production records.  In-use testing and SEA information is submitted on occasion, when EPA orders tests or audits a manufacturer. Defect investigations start on occasion, when a certain event triggers the need for it; but once the investigation starts, biannual reports are required. 
 
       TPEM notifications are submitted on occasion, when an equipment manufacturer decides to start participating in the program. Afterwards, annual reports must be submitted. Engine manufacturers also submit reports annually.
 
 
 6.  Estimating the Burden and Cost of the Collection
 
    6(a) Estimating Respondent Burden
 
 	Burden estimates were taken from previous ICRs and adjusted to reflect comments from fewer than ten respondents consulted by EPA [see Section 3(c)].  Tables 5 through 13 in the accompanying Excel file summarize the respondents' overall burden associated with this ICR. The tables are discussed in detail in sections 6(b)(ii) and 6(d) below.
    
    
    6(b) Estimating Respondent Costs
 
       6(b)(i) Estimating Burden Hours
 
      
	To estimate labor costs, EPA used the Bureau of Labor Statistics' (BLS) 2016 National Industry-specific Occupational Wage Estimates for the Engine, Turbine and Power Transmission Equipment Manufacturing Industry (NAICS 333600, available at https://www.bls.gov/oes/2016/may/naics4_333600.htm).  EPA used mean hourly rates increased by a factor of 2.1 to account for benefits and overhead, as listed in Table 6 below.

       6(b)(ii) Estimating Capital and Operations and Maintenance Costs
 
       Operation and Maintenance (O&M) costs for all programs are listed in Tables 5 through 13 in the accompanying Excel file. Wherever possible, estimates where developed using current costs. Where it was not practicable to obtain a new estimate, EPA used estimates developed in previous years and corrected them for inflation using the Bureau of Labor Statistic's Consumer Price Index Inflation Calculator. The calculator can be found at http://www.bls.gov/data/inflation_calculator.htm. 
 
 	Emissions testing is the largest cost in this collection. Many respondents are large companies which manufacture engines for two or more of the industries covered in this and other ICRs and have already invested in developing their own test cells. Engine manufacturers that have in-house testing facilities use them for all their certification and compliance testing needs as well as for research and development. The cost of maintaining these laboratories have been estimated at $81,237 per year (adjusted for inflation) and includes the cost of test fuels, calibration gases and equipment. Small companies with just a few engine families contract out testing services all around the world.  Table 15 lists the estimated cost of outsourcing emissions testing. Since manufacturers carry over emissions data from one model year to the next, this cost has been annualized over the approval period requested for this ICR (3 years). EPA does not expect any new engine manufacturers to build their own emission testing laboratories in the next three years. Therefore, capital costs are excluded from this ICR.

       Engine manufacturers are required to pay a fee with every certification application. This fee is requested under the authority of the CAA Section 217.  On February 20, 2018, EPA published the 2019 schedule of fees in the document CISD-18-02, which can be found at: https://iaspub.epa.gov/otaqpub/display_file.jsp?docid=41410&flag=1. The fees rule provides for a reduction in fee when "the full fee exceeds 1.0 percent of the projected aggregate retail price of all vehicles or engines covered by that certificate" (69 FR 26226, Section F).  The reduced fee must not exceed one percent of the aggregate retail price of the vehicles and engines covered by the certificate.   The relevant fees for calendar year 2015 are listed in Table 16.

 	For TPEM, the highest O&M cost is the bond equipment manufacturers must post for each piece of equipment brought into the US from abroad. While bond requirements mostly affect foreign equipment manufacturers, domestic manufacturers who own manufacturing plants abroad must also post a bond or obtain a waiver.  EPA has estimated the average bond at $5,000 and that 50 equipment manufacturers will need to post a bond each year for the next three years.
 
       Other O&M Costs associated with this information collection include electronic data storage, photocopying, shipping expenses, calls, and travel where applicable.

    6(c) Estimating Agency Burden
    
    
       Table 17 summarizes the EPA's and NHTSA's estimated burden associated with this collection.  The Compliance Division (CD), Office of Transportation and Air Quality, administers emissions certification and compliance programs. Within CD, the Diesel Engine Compliance Center (DECC), with offices in Washington, DC and Ann Arbor, MI, administers all nonroad programs. HD programs are split between the Gasoline Engine Compliance Center (GECC) and the Light-duty Vehicle Center. IT support is provided by the Data Analysis and Information Center. Approximately 20 CD employees dedicate most of their time (80% average) to the activities covered by this ICR at an estimated annual labor cost of $1,794,822 or $2,794,915 when increased by a factor of 1.6 to account for benefits and overhead. CD also gets support from two retired engineers, members of the Senior Environmental Employment Program (SEEP), and an administrative assistance at an annual total cost of $55,000 each. Other EPA employees provide part-time or indirect support for these activities. These include administrative assistants, IT personnel, agency lawyers at the Office of General Counsel (OGC) and the Office of Enforcement and Compliance Activities (OECA), contract managers, and upper management, among others. A similar labor mix of approximately 10 NHTSA employees increase overall labor costs by about $978,220.

       EPA and NHTSA contract out certain activities such as testing support, processing of reports, and help desks that answer questions from the public and the regulated industry. Two contracts support database development/maintenance and information security at a combined approximate cost of $530,000. Table 17 also list testing costs for various programs. Overall government costs amount to approximately $4,426,425,
    
    
       6(d) Estimating the Respondent Universe and Total Burden and Cost
       
       To estimate the respondent universe, EPA examined response levels in the last three years. Wherever possible, we based our estimates on 2017-2018 data. This section discusses our estimates as shown in Tables 5-13 in the accompanying Excel file.
 
       6(d)(i) Certification Estimates (see also Table 5, Excel file)
                                       
                                   Table 18
               Certification Response Levels Per Respondent Type
                                       
                                       

      
       Table 18 shows estimated certification response levels by type of respondent for the industries included in the Information Collection (IC) #1, Certification. Many manufacturers (respondents) certify engines/vehicles in more than one industry. Therefore, the real total of certification respondents is lower than the sum of manufacturers in each industry. After removing duplicates, there is an increase in the total number of manufacturers from the previous ICR (from 95 to 103) due to the addition of Marine CI, locomotive and HD GHG engine/vehicle manufacturers. There are 8 additional manufacturers which respond to IC#2, Alternative Fuel Conversions; up from 2 in this ICR's last review (ICR 1864.18). 
      
      The number of NRCI engine families decreased from 402 to 370. There is also a decrease in the estimated total of engine manufacturers participating in AB&T (41 vs. 31). Participation in ABT is voluntary for all sectors. Reliance on carry-over applications also increase from 56% of all applications in the previous review to an average of 80% now. Since burden and costs are significantly reduced in carry-over applications, this increase has a large impact in overall burden and costs. Recent IMO applications (4) were all carry-over, although the two manufacturers in that industry submitted 31 changes to their applications/certificates. IMO certificates are obtained only once as opposed to annually in other industries.
 
       6(d)(ii) Other Programs (see also Tables 5 through 13, Excel file)
 
      As discussed in section 4(b)(i)(6), there are two types of in-use testing programs. One program is run by the engine manufacturers, the other by EPA. Per 40 CFR Part 86, Subsection T, every year On average, EPA orders 6 manufacturers to test one engine family each. A minimum of five engines per engine family must be tested. HD engine manufacturers who receive test orders must find HD trucks in actual use. The engines must have been maintained according to the manufacturer's instructions and must have been on the road for a certain portion of their useful lives. Manufactures then installs equipment that measures real time emissions as the truck is driven. Some manufacturers pay an incentive to truck owners in return for letting them use their fleet. The incentive is voluntary and not mandated by EPA. However, we have accounted for this expense ($1,000 per truck) in our estimates.
       
       EPA also in-use tests, at its own expense, approximate 6 engines per year in the industries included in this ICR. These tests are conducted by contractors in cooperation with EPA staff.  EPA reviews the test results and analyzes the data to ascertain whether engines in fact comply with emission standard throughout their useful life, as prescribed by the Clean Air Act. No communication is established with the manufacturer unless there is a failure. The trucks/equipment used for these tests are leased from private fleets. EPA pays the going rate for those leases as any other customer would, thus rendering all activities associated with this program customary business practices. Therefore, no burden has been added to this collection request.
 
 	EPA plans to conduct two Selective Enforcement Audits per year in the sectors included in this collection request. For the purposes of this ICR, EPA has accounted for one audit in a company with its own in-house laboratory and one audit with a manufacturer who outsources testing.
 
      Engine manufacturers need to submit defect-related reports only when they learn that a significant number of properly maintained engines are affected by the same defect. Therefore, not all manufacturers that obtain certificates of conformity with emission regulations will submit defects reports every year. Based on response levels during the past two years, EPA expects to receive approximately 128 reports annually, (67 defects and investigation reports, and 61 voluntary emission recall/remediation reports) during the next three years. This is twice as many reports as we've received previously; yet the number of remedial plans remain low at six. The number of respondents increased from 29 to 35.
      
      TPEM participation levels have sharply decreased from 1462 engines and equipment manufacturers during the last ICR review to 107 now. This is because the program is coming to an end in 2021 and most participants exhausted their allowances early in the program. See section (4)(b)(i)(9) TPEM for details.
 
       As discussed in section (4)(b)(i)(10), there are regulatory provisions for a variety of special circumstances, from testing and display exemptions to national security. EPA's Imports and TPEM Help Desks, which also handle those provisions, receive about 3,272 questions from manufacturers and the public every year. Table 11 (Excel file) estimates the number of respondents that submitted applications and reports for special provisions covered under this ICR. In the previous ICR, EPA mistakenly factored in all calls and emails serviced by our help desks to the burden calculations without realizing that those calls included requests for information about programs not covered in this collection.
       
		(6)(d)(iii) Total Number of Reports per Respondent 

	The number of reports each respondent submits per year varies depending on several factors, such as: (1) number of engine families certified each model year and their projected production, (2) the requirements of any compliance program each family must comply with, (3) the number of corrections to the application for certification needed throughout the year; and (4) whether the respondent elects to participate in TPEM or other special provisions, such as testing or display exemptions.  The total number of responses for this collection has been calculated at 2,913 by a total of 468 respondent for an average number of responses per respondent of 6.2; as shown in Table 19. There is a sharp decline in the number of respondents and responses for two reasons: (1) As previously mentioned, TPEM has ended for many former respondents. The program was/is available at different times for different power categories and according to emissions standards. The program has already ended for the most popular categories and will end altogether in 2021; (2) The number of respondents to special provisions has been adjusted down. In the previous ICR, EPA mistakenly accounted calls serviced by our help desks for special provisions not covered in this ICR.

    6(f) Change in Burden 
 
    There is a net decrease of 73,137 hours in the total estimated burden for ICR 1684.20 from the burden currently identified in the OMB Inventory of Approved ICR Burdens of 3,880 for the previous ICR 1684.18.  This net decrease occurs despite the incorporation of four other ICRs into ICR 1684.20 as discussed in Section 1(b) of this document. Table 21 shows the change in the number of responses and burden in this ICR and the reasons for those changes. As mentioned in Section 6(d)(i), there is a sharp reduction in respondents in ICs #3 and #4 due to:
 A 92% decrease in TPEM respondents as the program phases out. According to 2017 data, there are 107 companies currently participating in TPEM as opposed to 1,462 respondents estimated during the previous ICR review (ICR 1684.18). Program availability varies by power category and schedule of emissions standards. The most popular Tier 3 period of availability has already ended for all but one power category. TPEM will end altogether in 2021. 
 Respondents' heavy reliance on carry-over testing data: 78% of all engine families certified in the past two years are carry-over families, an important increase from 56% in the previous ICR. 
 Other reductions were achieved by eliminating duplication. For example, in the previous ICR, EPA mistakenly accounted calls serviced by our help desks for special provisions not covered in this ICR.
