SUPPORTING STATEMENT  -  PART A

RECORDKEEPING AND REPORTING RELATED TO FUEL QUALITY REGULATIONS FOR DIESEL FUEL SOLD IN 2001 & LATER YEARS; FOR TAX-EXEMPT (DYED) HIGHWAY DIESEL FUEL; AND NON-ROAD LOCOMOTIVE & MARINE DIESEL FUEL: RENEWAL

DOCKET EPA-HQ-OAR-2007-1121
EPA ICR No.:  1718.09

1.	IDENTIFICATION OF THE INFORMATION COLLECTION

	1(a)	Title of the Information Collection

Fuel Quality Regulations for Diesel Fuel Sold in 2001 & Later Years; for Tax-Exempt (Dyed) Highway Diesel Fuel; & Non-Road Locomotive & Marine Diesel Fuel (Renewal) 
EPA Control Number 1718.09, OMB Control Number: 2060-0308.

	1(b)	Short Characterization/Abstract

	This ICR renewal is related to EPA's diesel fuel regulations under 40 CFR Part 80, Subpart I, applicable to highway ("motor vehicle" or "MV") diesel fuel and non-road, locomotive and marine diesel fuel (NRLM) and heating oil (HO).  Most of the information collected under this ICR is used to evaluate compliance with the requirements of the regulations.  Since virtually all MV diesel fuel was required to meet a 15 part per million (ppm) standard as of June 1, 2010, very little reporting related to MV diesel fuel remains.  However, reporting related to NRLM and HO will continue throughout the course of this proposed ICR renewal.  The activities associated with this ICR include:  registration (all parties have registered; updates to existing registrations are still possible); compliance reports (mostly covering NRLM and HO; updates to prior compliance reports for MV diesel are still possible); research and development (R&D) exemptions; generation and retention of quality assurance (QA) records; foreign refiner recordkeeping and reporting; placement of Product Transfer Documents (PTD) codes (a typically automated process, to indicate the presence of dye in tax-exempt fuel and/or sulfur content).  This ICR renewal contains provisions related to qualification of laboratories on performance-based test methods.  Virtually all applications have already been received from laboratories and acted upon by EPA.      

	 

2.	NEED FOR AND USE OF THE COLLECTION

	2(a)	Need/Authority for the Collection

	This supporting statement covers the recordkeeping and reporting requirements and the associated costs to various parties (e.g., refiners, importers, distributors, and retailers of diesel fuel).  These general recordkeeping and requirements are necessary to enable the Administrator to:

	(1) Identify the sources of diesel fuel; and

	(2) Ensure that these sources comply with the standards and limitations of the rules.

	An effective enforcement scheme is necessary to ensure that the environmental goals of the diesel program are met, and that those complying with the requirements in good faith are not disadvantaged by non-complying parties.  The diesel program requirements create a significant economic incentive for noncompliance.  

		For performance-based qualification of test methods for diesel fuel, reported data will enable EPA to:

	1)  Qualify laboratories to use test methods based upon accuracy and precision criteria supported by industry.

	2)  Ensure that diesel fuel and heating oil meet the standards required under the regulations at 40 CFR Part 80 and that the associated benefits to human health and the environment are realized.

	2(b)	Practical Utility/Users of the Data

	EPA will use the information contained in the reports required by this information collection to evaluate the compliance of parties involved in the production and importation of diesel with the diesel fuel requirements.  These reports will also be used by EPA to target compliance investigations. 

	PTDs maintained by parties in the diesel fuel distribution system and records related to diesel blending will be used to evaluate the compliance of the parties that maintain the records, and to help evaluate upstream compliance. PTDs are normally generated and retained in the course of business (i.e., they are customary business practices or "CBP"). There is a small burden associated with the placement of sulfur content and/or dye notices, a process which is typically automated.

	The automatically printed notice on tax-exempt highway diesel product transfer documents (which EPA allows to be stated in coded form to save space), allows both EPA to determine if dyed product is intended for highway use or is high sulfur diesel for off-road use only.  It also helps industry to make this determination.  

	The EPA's Office of Enforcement and Compliance Assurance, Air Enforcement Division is the governmental user of the information contained in the required records.

3.	NONDUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA

	3(a)	Non-Duplication

	Efforts have been made to eliminate duplication in this information collection. Where possible, information requirements from various organizations within the Agency have been combined to minimize the submittal of duplicate information in different formats.  The information in this collection will not be available from another source. 

	
	3(b)	Public Notice Prior to Submission to OMB

	EPA solicited public comment by means of a Federal Register Notice published on August 18, 2011, 76 FR 51362.  The Notice requested public comment through October 17, 2011. No comments were received.  
			
	3(c)	Consultations

	EPA will discuss this information collection with representatives of regulated industry.  We are soliciting comments via the Federal Register notice, as well.  This supporting statement and our estimates are being placed in the public docket.  On November 21, 2011, we sent the estimates to members of the regulated community in an effort to solicit input.  Currently we have received no comments. 
	
	3(d)	Effect of Less Frequent Collection

	The diesel rule requires refiners and importers to submit annual reports which will, by the information contained therein, demonstrate a party's compliance with the applicable sulfur standards.  Less frequent submittal of such reports would severely hinder EPA's ability to monitor compliance, and would likely lead to noncompliance. In the case of the dye requirements, a less frequent collection is not practical, since the information must appear on product transfer documents at the time custody is transferred

	3(e)	General Guidelines

	The requirement requires record retention for five (5) years.  The Agency believes this is important to the success of the program.  With the large economic incentive to not comply that exists because of the substantial difference in price that can exist between low sulfur diesel and high sulfur diesel, it is imperative that EPA maintain deterrence by assuring that all parties know that EPA will be able to distinguish the difference between high sulfur and low sulfur deliveries via a review of records generated in the normal course of business (i.e., CBP).   The requirement to retain for 5 years is consistent with other record retention periods in the fuels regulations, with the applicable 5 year statute of limitations, and CBP.  Most entities already keep these records for 5 or more years for tax and other business purposes.        

	3(f)	Confidentiality
	
	Proprietary information is routinely submitted by refiners and importers as part of annual reports and as part of requests for research and development or hardship exemptions.  Confidentiality for such information is covered by established Agency procedures and the regulations at 40 CFR Part 2.

	3(g)	Sensitive Questions

	No questions of a sensitive nature are asked in this information collection.

4.	THE RESPONDENTS AND THE INFORMATION COLLECTED

	4(b)	Information Requested

1.  Data Items

Knowledge of the following definitions at 40 CFR Part 2 is important for a thorough understanding of the reporting and recordkeeping requirements:

"Diesel fuel" means any fuel sold in any state or Territory of the United States and suitable for use in diesel motor vehicles, diesel motor vehicle engines or diesel non-road engines, and which is commonly or commercially known or sold as diesel fuel.

"Motor vehicle diesel fuel" means any diesel fuel, or any distillate product, that is used, intended for use, or made available for use, as a fuel in diesel motor vehicles or diesel motor vehicle engines.

"Refinery" means a plant in the United States at which gasoline or diesel fuel is produced.

"Foreign refinery" means a refinery that is located outside the United States.

"Refiner" means any person who owns leases, operates, controls, or supervises a refinery.

"Importer" means a person who imports gasoline, gasoline blending stocks or components, or diesel from a foreign country into the United States (including the Commonwealth of Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands.

"Sulfur percentage" is the percentage of sulfur in diesel fuel by weight, as determined using one of the test methods specified in the regulations.

"Batch of motor vehicle diesel fuel" means a quantity of diesel fuel which is homogenous with regard to those properties that are specified for motor vehicle diesel fuel under 40 CFR subpart I.

 5.  THE INFORMATION COLLECTED - AGENCY ACTIVITIES, COLLECTION METHODOLOGY, AND INFORMATION MANAGEMENT
 
 	5(a)	Agency Activities							
 
   *          All reported compliance data will be reviewed by EPA.
   *          EPA will contact submitters about problem submissions.
   *          Where appropriate, we will prepare a written response to the submitter.
   *          The data will be stored.
	
 	5(b)	Collection Methodology and Management
 
 	EPA  accepts common electronic formats for most of the reporting requirements - for example, annual reports may be submitted in any of several commercial spreadsheet formats or, more simply, as comma-delimited text/comma-separated value fields. 
  
 	The product transfer document information can be included on standard transfer documentation customarily used in the ordinary course of business (i.e., CBP).  EPA allows the information to be encoded by upstream parties (refiners, importers, and terminals) to facilitate reporting and save space.						
 
 	The information is carefully reviewed for compliance with the requirements.  Most of the information submitted to the Agency is claimed as business confidential.  It is stored in a secure area and in a secure database.
 
 	5(c)	Small Entity Flexibility
 
 	The information collection reduces to the extent practicable and appropriate the burden on respondents, including small entities.  The major reporting requirements apply to refiners and importers of diesel, which are not usually small businesses.  
 
 6.	ESTIMATING THE BURDEN AND COST OF THE COLLECTION
 
 	6.	Estimating the Burden and Cost of Collection
 
 a.	Estimating the Respondent Universe 
 
 	We drew upon experience implementing similar regulations among the same and similar entities to develop estimates of the burden associated with this collection.  
 
 	
 
  b.	 Estimating Respondent Costs
 
      (i) Estimating Labor Costs
 
 In discussions with industry, four labor categories were identified as having involvement: managerial, legal, professional/technical (prof/tech) and clerical.  According to the Bureau of Labor Statistics, May 2008 National Industry-Specific Occupational Employment and Wage Estimates, mean wages were:
 
 Wages
 Managerial 	$61.42 per hour
 Legal		$85.56 per hour
 Prof/Tech	$61.05 per hour
 Clerical	$18.34 per hour
 
 Doubling for company overhead and employing a 2% annual inflation factor to bring the rates to the year 2011, and, for convenience, rounding up to the nearest dollar, gives the following rates that will be used for this ICR:
 
 Total Employer Cost
 Managerial	$126
 Legal		$175
 Prof/Tech	$125
 Clerical	$  38
 
 The labor mix for each task is assumed to be about 0.05 hour managerial, 0.05 hour legal, 0.7 hour professional/technical, and 0.2 hour clerical.  This gives an average labor cost of about $110 per hour, which will be used in this ICR.  Our estimates are summarized in the following table.
 
 There are no Operations & Maintenance (O&M) costs associated with this Information Collection Request (ICR).

 	6(c)	Estimating Agency Burden and Cost
 
 	The Agency activities listed in 5(a) are part of an overall gasoline and diesel reporting system (including reformulated gasoline, conventional gasoline, and diesel).  We estimate that this system costs approximately $120,000 in personnel costs per year (i.e. approximately (3/4) of a GS-13 employee with consideration of overhead and benefits).      
 
 6(d) and (e)	Estimating the Respondent Universe and Total Burden and Costs, and Bottom Line Burden Hours and Costs
 
 	This was incorporated into 6(a) and (b).
 
 	6(f)	Reasons for Change in Burden
 
 	For this renewal, we estimate a total annual burden of 265,406 responses, taking 18,950 hours, and costing $2,084,500.  For the expiring approval, we had estimated 426,275 responses, taking 285,261 hours, and costing $2,626,000.  Most MV diesel reporting has now ended, which was expected to reduce (and has reduced) the responses, hours, and costs.  Likewise, laboratory qualifications have virtually all been submitted already.  However, please note that we have changed how we accounted for the burden for this renewal.  We have modeled our estimates to match the in-use forms in order to assist interested parties in providing comments.  Therefore, some of the change is associated with how we did the estimates in 2008 (expiring approval) and now.
 
 	The Agency burden has decreased because of a reduction in the number of reports filed.  In the expiring approval, we estimated a total cost of $668,000.  We estimate that the cost associated with this renewal is approximately $120,000.    							
 										
 	6(g)	Burden Statement
 
       The public reporting burden for this Environmental Protection Agency (EPA) collection of information is estimated to average .07 hours per response.  This includes time for reviewing instructions and regulations, searching company records, gathering the needed data, and completing, reviewing, copying, and transmitting the collection of information.  Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency.  This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions or requirements; train personnel to be able to response to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.  An Agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number.  The OMB control numbers for EPA's regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15.	
 
 	To comment on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including the use of automated collection techniques, EPA has established a public docket for this ICR under Docket ID Number EPA-HQ-OAR-2007-1121, which is available for online viewing at www.regulations.gov, or in person viewing at the Air and Radiation Docket and Information Center in the EPA Docket Center (EPA/DC), EPA West, Room 3334, 1301 Constitution Avenue, NW, Washington, D.C.  The EPA Docket Center Public Reading Room is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal holidays.  The telephone number for the Reading Room is (202) 566-1744, and the telephone number for the Air and Radiation Docket and Information Center is (202) 566-1742.  An electronic version of the public docket is available at www.regulations.gov.  This site can be used to submit or view public comments, access the index listing of the contents of the public docket, and to access those documents in the public docket that are available electronically.  When in the system, select "search," then key in the Docket ID Number identified above.  Also, you can send comments to the Office of Information and Regulatory Affairs, Office of Management and Budget, 725 17th Street, NW, Washington, D.C. 20503, Attention:  Desk Officer for EPA.  Please include the EPA Docket ID Number EPA-HQ-OAR-2007-1121 and OMB Control Number 2060-0308 in any correspondence.
