oEPA Office of Transportation and Air Quality EPA420-F-05-013 March 2005 Questions and Answers on the Clean Diesel Fuel Rules The following are responses to questions received by the Environmental Protection Agency (EPA) concerning the manner in which the EPA intends to implement and assure compliance with the diesel fuel sulfur regulations at 40 CFR Part 80. This document was prepared by EPA's Office of Air and Radiation, Office of Transportation and Air Quality, and the Office of Enforcement and Compliance Assurance, Office of Regulatory Enforcement. Regulated parties may use this document to aid in achieving compliance with the diesel fuel sulfur regulations. However, this document does not in any way alter the requirements of these regulations. While the answers provided in this document represent the Agency's interpretation and general plans for implementation of the regulations at this time, some of the responses may change as additional information becomes available or as the Agency further considers certain issues. This guidance document does not establish or change legal rights or obligations. It does not establish binding rules or requirements and is not fully determinative of the issues addressed. Agency decisions in any particular case will be made applying the law and regulations on the basis of specific facts and actual action. While we have attempted to include answers to all questions received to date, the necessity for policy decisions and/or resource constraints may have prevented the inclusion of certain questions. Questions not answered in this document may be answered in a subsequent document. The Agency intends to provide any additional responses as expeditiously as possible. Questions that merely require a justification of the regulations, or that have previously been answered or discussed in the preamble to the regulations have been omitted. ------- ------- Table of Contents 1.

Designate and Track (D&T) Issues 1.1: When is EPA's Designate and Track (D&T) reporting mechanism expected to be completed? A: D&T reporting will be an electronic reporting system, similar to the existing Tier 2 Gasoline Sulfur reporting program. Reports will be a flat file format based on spreadsheet templates. Additionally, we are working with EPA 's Office of Environmental Information on a pilot project for accepting Confidential Business Information (CBI) through EPA 's Central Data Exchange (CDX). CDX will enable us to utilize digital signatures and eliminate our dependency on a hybrid reporting system where electronic data must be accompanied by a hardcopy printout and certification with a "wet ink" signature. The CDXpilot is scheduled for completion February 2006. Reporting parties for RFG & Anti-dumping and Tier 2 Gasoline Sulfur will be the first users of this system. 1.2: We understand that many ULSD designated "facilities" are currently unregistered with EPA. They must apply for a registration or permit number by December 2005 in order to get a registration number by the NRLM rule's effective date. There is currently no application mechanism. A: The RFG & Anti-dumping registration system will be the basis for ULSD registration and similar procedures will apply. Companies that have an existing Company ID with RFG & Anti-dumping may add ULSD facilities, while companies not registered with RFG & Anti-dumping will need to request Company and Facility IDs. Registration will be done using forms to be posted on OTAQ's Fuel and Fuel Additives Reporting Forms web page. Registration forms will be made available in the first quarter of2005. 1.3: Section 80.535 of the NRLM rule allows refiners to produce early credit NRLM low- sulfur (500 ppm) diesel. If undyed, this low-sulfur NRLM diesel is considered on-road fuel UNLESS it is designated as NRLM or LM diesel fuel. The NRLM early credit rule takes effect June of 2006. We will therefore need a registration number by June 1, 2006 in order to move early credit NR low-sulfur diesel fungibly with on-road. Is this correct? A: Yes. Refinery designation requirements begin June 1, 2006, as well as several other provisions, including Product Transfer Documents (PTDs). Therefore, facility registration would be required prior to June 1, 2006. This is not limited to the NRLM early credit fuel. 1.4: In addition, company software professionals will need at least 6 months to incorporate any external reporting system into the company software. What is the anticipated process and timing for developing the D&T reporting software? When will D&T ------- software, or standards, be available to develop systems to feed them? A: EPA is not developing reporting software. The reporting process will be similar to the Tier 2 Gasoline Sulfur system -flat file, text or spreadsheet submission. Common practice is for EPA to share draft versions offorms with third party software vendors and industry representatives (AOPL, API, NPRA, etc.) for review and comment. Report Form instructions and templates for D&T will be made available on the OTAQ Fuel and Fuel Additives Reporting Forms web page by the end of2005. 1.5: Most of the receipt and delivery facilities that pipelines operate do not have EPA registration numbers required to implement D&T. If a terminal receives product from several pipelines, each one will require a registration number for that custody transfer. Is EPA ready to process the volume of applications required? When will the registration applications be available? A: EPA will process ULSD facility registration applications in a timely manner and anticipates no difficulty in doing so. Registration will be done using forms to be posted on OTAQ's Fuel and Fuel Additives Reporting Forms web page. Registration forms will be made available in the first quarter of2005 or sooner. 1.6: If a pipeline does not handle 500 ppm highway fuel, it appears that they are still required to file D&T reports, is this correct? Systems cannot opt out of D&T by handling only certain products? A: All facilities are required to compile andfile D&T reports if they handle any designated fuel upstream of the point where taxes are assessed, and dye and/or marker is added if required. This includes a pipeline that does not handle any 500 ppm highway diesel fuel. In that case, the D&T reports would confirm that the pipeline did not handle this highway fuel, and did not violate any of the restrictions on redesignating off-roadfuel as highway fuel. The D&T reports from this pipeline would also be used in evaluating compliance by the parties before and after this pipeline in the distribution system. This pipeline is only one step in a chain offuel hand-offs, and the D&T system is designed to use information from each party to a hand-off to ensure compliance by all of the parties in the chain of distribution. 1.7: Will refiners be required to provide data sheets, or other types of testing data to insure pipelines receive the correct product? A: Refiners are required to maintain batch testing records which demonstrate compliance with the applicable sulfur standard. The PTD that accompanies the transfer of a batch of designatedfuel from a refiner to a pipeline operator must correctly identify the sulfur standard to which the fuel complies. However, there 2 ------- is no EPA requirement that testing records accompany the batch of fuel when it is transferred to the custody of a pipeline operator. Any private requirements established between refiners and pipelines, would be business decisions that are separate from EPA 's regulations. 1.8: What is the plain English clarification of 80.598(b)(9)(vii)(B) and 80.599(b)(5)? A: The regulations limit the volume of500 ppm NRLM that may be redesignated as highway 500 ppm by fuel distributors. Section 80.598(b)(9)(vii)(B) applies to distributors other than truck loading terminals. To ensure that there are no significant redesignations over the annual compliance period for these facilities, the volume of500 ppm sulfur highway diesel fuel that a facility discharges from it's custody must be no greater than 102 percent of the volume of500 ppm sulfur highway fuel that the facility received during the annual compliance period, taking into account inventory change. This provides pipelines and other parties upstream of truck loading terminals a tolerance of 2% during the annual compliance period to account for metering differences, volume swell, and the like. See 69 Fed. Reg. 39070 (June 29, 2004). Section 80.599(b)(5) requires that diesel fuel greater than 500 ppm sulfur must be designated as a fuel other than 15 ppm or 500 ppm highway or NRLM. For example, it can be designated as heating oil or another diesel fuel that can lawfully be above 500 ppm. Requiring a proper designation for high sulfur diesel fuel is the first step in ensuring that it stays segregated from fuel that is supposed to meet the 15 ppm or 500 ppm sulfur level. 1.9: What are the Designate & Track Quarterly and Annual start and finish dates? The Quarterly Compliance Periods listed in 80.599 begin June 1, 2007 and end September 30, 2010, but the Quarterly Reporting listed in 80.601 begins November 30, 2007 and ends August 31, 2010. Why would the report period end before the compliance period? There is a similar issue with the Annual report versus compliance dates. A: The dates for the quarterly and annual compliance periods and reporting dates were incorrect in the Final Nonroad Rule regulations but were correct in the preamble (69 FR 39100, June 29, 2004). We intend to correct this error in a future technical amendment to the regulations. The correct preamble dates for the compliance periods and reporting dates are as follows: Quarterly Compliance Periods and Reporting Dates Quarterly Compliance Period*: Report Due Date: July 1 through September 30 November 30 October 1 through December 31 February 28 January 1 through March 31 May 31 3 ------- April 1 through June 30 August 31 * The first quarterly reporting period will be from June 1, 2007 through September 30, 2007 and the last quarterly compliance period will be from April 1, 2010 through May 31, 2010. Annual Compliance Periods and Reporting Dates Annual Compliance Period: Report Due Date: June 1, 2007 - June 30, 2008 August 31 July 1, 2008 - June 30, 2009 August 31 July 1, 2009 - May 31, 2010 August 31 June 1, 2010 - June 30, 2011 August 31 July 1,2011- May 31, 2012 August 31 June 1, 2012 - June 30, 2013 August 31 July 1, 2013 - May 31, 2014 August 31 June 1, 2014 - June 30, 2015 August 31 July 1, 2015 - June 30, 2016 August 31 1.10: Is downstream D&T no longer required in 2010 or in 2015 or ever? A: The downstream D&T provisions change over time, as the standards change and more of the highway and off-highway diesel fuel becomes subject to the 15 ppm refinery gate standard. In general, downstream parties will always have to designate the diesel fuel they transfer, as part of the PTD requirements. However over time there will be less need to track various kinds of diesel fuels andfewer volume balances that will apply. After May 2014 the only tracking and related volume balances that will apply downstream involve heating oil and 500 ppm LM, to avoid improper transfer of low sulfur heating oil into the LM market. 1.11: If only credit fuel is sold into the heating oil market, does a marker need to be added? Does a pipeline need to track if not receiving heating oil into its system? Same for the marker in L&M, if only credit 500 ppm NR is received and no 500 ppm L&M, does it need to mark and does it need to track? A: First, the requirement to mark heating oil is limited to heating oil used in certain parts of the country. In general, the marker does not need to be added to diesel fuel distributedfrom a terminal within the northeast and mid-Atlantic area and Alaska, for use in those areas. That means the great bulk of the heating oil market is not subject to a marking requirement. For heating oil produced or 4 ------- distributed outside those areas, the terminal is required to mark heating oil prior to distribution from the truck loading terminal. If the fuel is designated as something other than heating oil, then it does not need to be marked, and will be subject to the sulfur level applicable to its designation. Outside the areas noted above, any diesel fuel that is not marked is presumed to not be heating oil, and typically will be considered motor vehicle or NRLMfuel and subject to the appropriate sulfur standard. Therefore, if it is designated as NRLM, it is not treated as heating fuel, but rather NRLM and it does not need to have the marker added. NRLM can always be used as heating oil or LM diesel fuel, without any change in its designation, however it remains subject to the sulfur standard that applies to its NRLM or LM designation. If the NRLM is redesignated as heating oil, it would need to be marked at the terminal. Similarly, if it is designated as NR fuel, and not L&M, then no marker needs to be added unless it is redesignated as LM. Any pipeline that receives designated fuels (including high sulfur NRLM, and credit 500 ppm NR fuel) must comply with the designate and track requirements. This information is essential for downstream parties to be able to demonstrate their compliance with the marker requirements for heating oil and 500 ppm LM fuel (from 2010-2012). It will also be used by EPA to verify the compliance of parties who receive fuel from the subject pipeline by allowing us to compare the volumes of designatedfuels reported as receivedfrom the pipeline with the volumes reported delivered by the pipeline. 1.12: Do pipelines without truck loading terminals need to submit quarterly D&T reports or just annual D&T reports? A: Pipelines without truck terminals must submit both annual and quarterly reports prior to July 1, 2010. The quarterly reports will contain the information on receipts and deliveries of designatedfuel volumes. The annual reports will contain information to show compliance with volume balance requirements over the annual compliance period. Beginning, July 1, 2011, only annual reports need to be submitted (see chart on quarterly and annual compliance dates, in question 1.9), and compliance with volume balance requirements continues to be on an annual basis. 1.13: In the definition of facility, can a common carrier pipeline be aggregated with any other non-common carrier terminals if they are all owned by the same parent company? A: Yes, if certain conditions are met. First, a single entity, in this case, the parent company must maintain custody of the fuel at all times in the aggregated facility (i.e. the parent company must maintain custody at all subsidiary/leased terminals defined as part of that aggregatedfacility). If the parent company/entity fails to 5 ------- maintain custody of the fuel at any point, that point cannot be considered part of the aggregated facility. In addition, the choice to treat places as aggregated or separate facilities may not be changed by the entity during any applicable compliance period. If a refinery is part of the aggregatedfacility, the common carrier pipeline may not be included as part of the aggregated facility. 1.14: If an entity, for a facility (as those terms are defined in 40 C.F.R. § 80.502), chooses a single registration number for its refinery, pipeline, and terminal (thus creating an 'aggregated facility'), does this mean that in the event of finding product in violation of the diesel fuel regulations, only the registered entity will be subject to civil penalty, and not all 3 portions of the system separately? A: It is dependent on the type of violation. For volume balances, liability falls on the entity in relation to its facility. The volume balance is calculated over the entire aggregated facility that is registered, and the entity that registered the facility will be subject to the penalty. For other violations (such as violations of the applicable sulfur level of a batch offuel), the liability is not limited. The fact that the terminal is aggregated with a pipeline and refinery for volume balance purposes is only relevant to this violation because it means, by the definition of an aggregated facility, that the entity has custody of the fuel at all locations. However any other entity or person who takes custody of the fuel may also be subject to presumptive liability. 1.15: At the terminal, if a pour point depressant, conductivity improver, lubricity improver which is compliant to the 15 ppm standard is injected, must the terminal operator register as a refiner? A: Injecting such additives to a batch of fuel would not make a terminal operator a refiner. 1.16: Some pipeline and marine terminals receive fuel from multiple refineries. Will they need separate facility ID numbers? A: The terminal owner must obtain a facility ID for its facility, subject to any ability to lawfully aggregate into a larger facility. The fact that the terminal facility receives fuel from various refineries does not change the fact that it is a still a single place in the distribution system that is owned by a single entity. Similarly, a pipeline receives a single ID for a single facility notwithstanding how many refineries supply fuel to that facility. Consequently, the terminal in this situation would need only one facility ID number for its terminal operations. However, if fuel is imported into the terminal, or the terminal acts as a refiner, the terminal will need to state such activity, in addition to the other quarterly reporting requirements of § 80.601, and additionally will have annual reporting requirements of § 80.604. The party will also need to register as a refiner or 6 ------- importer, and meet all applicable refiner or importer requirements, but that would not change the facility ID that goes with the terminal facility. 1.17: If a company has two (or more) refineries and transfers highway diesel blendstocks between refineries, are they precluded from aggregating? A: Refineries are precludedfrom aggregating with other refineries. 1.18: If a terminal has 15 ppm No. 2 and 500 ppm kerosene (No. 1), can a truck blend the two (winter blending) and take 500 ppm to the pump at retail? Who is responsible for the downgrading accounting? A: The two fuels can be blended as long as the appropriate volume balances are met. When the terminal received the 15 ppm No. 2, it would have been designated as highway or NRLM. The limit on downgrading applies to No. 2 15 ppm highway diesel fuel that the terminal receives, and restricts the ability of the terminal to redesignate it as 500 ppm highway. Both the terminal and the truck transporter would have to meet the anti-downgrading and any other applicable volume balances, based on comparing the volumes and designations of fuel they received to fuel delivered. Since accounting responsibility is keyed to what you received and delivered, it will make a difference whether the blending occurred before or after custody was transferred. For example, if the blending occurs before the terminal transfers custody, then the terminal has to account for the blendedfuel in its delivery accounting. If blending occurred after the transfer of custody, then the truck transporter will have to account for the blendedfuel in its delivery accounting. 1.19: In attempting to balance reporting requirements, if a pipeline ticket is generated for a particular amount of barrels/gallons, a terminal will have a natural gain or loss. Do you have a tolerance or must it match exactly? A: The reported hand-off volumes must match - there is no tolerance. However, to account for gains and losses in the system, the D&T provisions allow for a 2% gain/loss over the course of the annual compliance period for pipelines. See answer to question 1.8, above. For terminals, there is no such specific tolerance, however, they have the ability to adjust by redesignating volumes accordingly. 1.20: Who is responsible for the product if it comes in to the terminal (from a pipeline) over 15 ppm? A: Presumptive liability under 40 C.F.R. § 80.612 applies to the party in possession of the contaminated fuel (in this case, the terminal after it has taken custody) and to all parties upstream of the facility where the violation is found (including, in this case, the pipeline). Each party has an opportunity to establish a defense to 7 ------- liability. Until it is proven which party is at fault, all parties involved in the production and distribution of the product will be presumed liable. 1.21: Please confirm that a terminal operator selling 500 ppm nonroad diesel outside the (Northeast/Mid-Atlantic) NE/MA Area does not have to add the marker because that fuel need not be differentiated from higher sulfur (greater than 500 ppm) nonroad diesel fuel generated by credits. A: Only diesel fuel designated as heating oil need be marked if it is distributedfrom either a terminal outside of the NE/MA Area or a terminal inside the NE/MA Area for delivery outside of the Area. Beginning in 2007, all heating oil must contain the marker outside the NE/MA area. From 2010 to 2012, fuel designated as 500 ppm LMfuel also must contain the marker. In this instance the terminal selling the 500 ppm fuel does not have to add a marker unless it is either heating oil or, during 2010 to 2012, LMfuel. If it is not marked, then it will be treated as subject to the appropriate sulfur standard. The terminal selling the high sulfur fuel would need to mark the fuel if it is heating oil. The high sulfur fuel could not be designated as 500 ppm LM, so the LM marking requirement should not apply. 1.22: A company owns a refinery and ships its product via a common carrier pipeline it owns (and now exclusively uses) to a terminal that it owns. Can these facilities be aggregated, or does the fact that the company's pipeline is a common carrier pipeline preclude aggregation? A: As stated in the regulation (§ 80.502(b)(1)), facilities may be aggregated if custody is maintained by one entity that owns those specific facilities. Per § 80.502(b)(2), refineries may only be aggregated with facilities that do not receive fuel from other refineries or import facilities. In the case stated here, the "common carrier " status of the pipeline does not matter if the pipeline is not receiving fuel from other entities. The common carrier pipeline example that was used in the regulations was only meant to refer to the typical case where an entity receives fuel from various sources, and thus would not meet the criteria for facility aggregation. 1.23: If a company redesignates, please explain how to restore volumes so that required volume balances are met. A: The volume balance requirements limit certain types of redesignations, unless the volume balance is met over the compliance period. For example, during a compliance period a terminal may redesignate NRLM as highway fuel as long as over the compliance period the terminal meets the required volume balance. If a terminal has been receiving fuel designated as NRLM and delivering some of it as 8 ------- highway and some as NRLM, the volume balance on highway fuel could go negative during that compliance period. To offset this, the terminal would have to take delivery of the fuel designated as highway and redesignate enough of it as NRLM to satisfy the volume balance. 1.24: How will a terminal designate a mixture of transmix and "off-spec" fuel that might be a combination of 15 ppm, all grades of 500 ppm, heating oil, and jet fuel? Will this designation(s) limit the marketing options of a transmix handler beyond the limits that would be imposed strictly by the sulfur content of the mixture alone? A: The designation is left to the terminal. The designation must be clear and accurate, therefore the sulfur level of the mixture will limit the designation options. Beyond that, the designate and track compliance calculations have been designed to minimize, if not eliminate, any unintended marketing limitations. 1.25: According to the preamble (page 39067), "EPA intends to work with industry subsequent to this final rule to provide guidance regarding facility boundary and aggregation decisions that will address the many unique situations." It appears from the discussion in the preamble that such "unique situations" are present when the same entity owns and operates a series of locations in the distribution system. Under the rule, the entity may choose whether to aggregate or to treat the separate locations as separate facilities. It would appear that such guidance might not be necessary, because an entity has the flexibility under the rule to determine where to draw lines around its facilities, so long as each facility meets the definition of "facility" under the rule. What is EPA's intent with regard to such guidance? When can industry expect to become part of these discussions? Has EPA developed a working list of the "unique situations"? Is EPA's intent with the guidance to address the definition of a "facility" and to help the regulated community understand the parameters of a facility? A: In addition to this Question/Answer document, EPA will also be releasing a Small Entity Compliance Guide to assist small entities in complying with the requirements of the rulemaking. It was our intention that the presentations and discussions that occurred at the Clean Diesel Fuel Workshop in November 2004 would help to clarify and address questions and/or concerns that industry had regarding the definition of "facility. " We will also answer any other questions as they arise and will continue to work with the fuel industry to ensure a smooth transition to ultra low sulfur dieselfuels. 1.26: When will the new technology vehicles start being sold (i.e. what is the absolute target date for ULSD at the pump)? A: Heavy-duty vehicle model years typically start on January 1. However, they could start several months earlier and medium-duty vehicles often do. Light-duty vehicle model years typically start even earlier. We designed the program with a 9 ------- retail target date of September 1, 2006. The regulations set out the dates when fuel must meet the sulfur standards at various points in the distribution system. The regulations also prohibit selling anything other than 15 ppm sulfur dieselfuel to 2007 or later model year highway vehicles. 1.27: My company is co-owner of a single physical pipeline that is operated as if it were two separate pipelines. Each of the co-owners has a set fraction of the pipeline's capacity and has established its own tariff rates which it charges to its customers. May each of the co- owners obtain a separate facility registration under the designate and track system with respect to its operations on this pipeline? A: Section 80.502(b)(5) of the diesel fuel regulations states that a contiguous pipeline may not be subdivided into more than one facility. Based on this, your pipeline could not be subdivided into two facilities with separate facility registrations. EPA adopted this requirement because we believe that allowing an individual pipeline to be subdividedfor D&Tfacility registration purposes would severely impact EPA's ability to evaluate compliance and assign liability for potential violations. 1.28: My company imports diesel fuel into storage tanks that we lease at a terminal in New England. Please explain the responsibilities of the importer and the terminal owner with respect to the designate and track requirements related to the importation of diesel fuel. A: The importer must register separately for each terminal facility into which it imports fuels. EPA will issue an import facility registration number for the importer that is composed of a numerical entity code and a numerical location code (the location being the terminal). The terminal owner will be provided with a terminal facility registration number composed of a location number (same as that supplied to the importer) and an entity registration number. Alternately, if the importedfuel is certified before delivery to a U.S. terminal, then the importer may obtain a registration for a "virtual" off-shore import facility. In such cases, the importer will be given an import facility registration number applicable to the importation of fuel into any terminal located in a single PADD. It has been the practice for EPA to issue these types of "virtual" import facility registrations for imported gasoline. The importer must appropriately designate all importedfuels. For each of its registeredfacilities, the importer must also fulfill all of the record-keeping and reporting obligations applicable to an importer. For example, the importer must demonstrate compliance with the requirement that 80% of all highway diesel fuel it imports meets a 15ppm sulfur standard (2006-2010). The terminal owner must account for the volumes of designatedfuels that are imported into its terminal in demonstrating compliance with the volume balance 10 ------- and anti-downgrading requirements. 11 ------- 2. Handling/Downgrading Issues 2.1: As we understand it, the rule provides that interface/transmix may be sold as heating oil or high-sulfur NRLM from June 1, 2007 through May 31, 2010. During at least a portion of that time period, the sulfur standard for NRLM will be 500 ppm. Can the above-500 ppm transmix be blended into NRLM that has a sulfur content of 500 ppm or less? If so, what happens if the blending causes the sulfur content of the entire tank to exceed 500 ppm? A: Blending of greater than 500 ppm NRLMfuel with 500 ppm NRLMfuel is allowed. However, the entity performing the blending takes on the liability for the blend meeting its designation. If the resulting blend is greater than 500 ppm, then the entire batch of fuel must be designated as high sulfur diesel fuel. This option is limited in certain cases by the volume balance requirements, which is based on a comparison of the amount of high sulfur NRLM received to the amount of high sulfur NRLM delivered. 2.2: If the two products mentioned in question 2.1, above, cannot be blended, do the regulations require the high-sulfur transmix to be loaded across a separate rack line and to be labeled differently on the bill of lading? A: As discussed in 2.1, in many cases they can be blended. However, if they are not, they would have different designations and require distinct product transfer documents. 2.3: How will Minnesota B2 (2% biodiesel) be treated under D&T? A: Minnesota B2 is diesel fuel, and is therefore subject to all of the requirements of diesel fuel. Biodiesel must comply with the same sulfur specification applicable to diesel fuel from any other source. If sold as ULSD or blended with ULSD for later sale as ULSD, the biodiesel would be required to meet the 15 ppm sulfur specification applicable to ULSD. The terminal would be subject to presumptive liability if their addition of biodiesel to ULSD caused the 15 ppm sulfur standard to be exceeded. 2.4: What is the terminal compliance date? August 1, 2006? A: The terminal compliance date for highway diesel fuel is July 15, 2006for all fuel they designate as 15 ppm diesel fuel. 2.5: When do downgrade limitation dates start for pipelines? A: Anti-downgrade limitations begin Oct 1, 2006for all entities in the distribution 12 ------- system. 2.6: What requirements are there for clean trucks? Will trucks be dedicated to ULSD service? This will have major impact on where testing occurs. A: There are no EPA requirements to use dedicated tank trucks to transport ULSD. It is the responsibility of the tank truck operator to ensure that whatever contamination that might take place while the ULSD is in the operator's custody does not cause the 15 ppm cap on sulfur content to be exceeded. Additional quality control measures may be needed to limit sulfur contamination if an operator chooses to use a tank truck compartment to alternately transport ULSD and high sulfur products. 2.7: What limitations, if any, are there on the marketing of transmix that has jet or exempted product? A: The special provisions applicable to the sale ofproducts produced by a transmix processor using transmix as the feedstock are applicable regardless of the composition of the transmix. As a result of common pipeline batch sequencing, we anticipate that most transmix will contain some jet fuel and in certain areas heating oil. From June 1, 2006 through May 31, 2010, 500 ppm diesel fuel produced by processing transmix may be designated as highway diesel fuel and sold into the highway diesel market (40 CFR 80.513(a)). This flexibility applies to facilities that produce diesel fuel by processing transmix by distillation or other refining processes, but do not produce diesel fuel by processing crude oil. This flexibility only applies to the volume of diesel fuel produced by a transmix processor by processing transmix, and does not apply to any diesel fuel produced by the blending of blendstocks. 2.8: Can a transmix processor produce 500 ppm diesel fuel for sale into the highway diesel market after June 1, 2006? May the transmix processor blend the fuel produced through the processing of transmix with a finished diesel fuel produced by a refiner (meeting a 15 ppm or 500 ppm sulfur cap) in order to ensure production of a final fuel blend that meets a 500 ppm sulfur cap for sale into the highway diesel pool? Without the ability to conduct such blending, the diesel fuel that transmix processors produce from transmix may not always meet a 500 ppm sulfur specification. This may limit the market for transmix-derived diesel fuel. A: In the case described in the question, the transmix processor could designate and sell all of the 500 ppm fuel volume produced by blending processed transmix and 500 ppm diesel fuel into the highway diesel market, provided that the finished 500 ppm diesel fuel usedfor blending had already been certified by another refiner and designated as highway diesel fuel. If the finished diesel fuel usedfor blending was designated as No. 1 or No. 2 15 ppm highway diesel fuel, then all of 13 ------- the resulting 500 ppm diesel fuel could also be sold into the highway diesel market. However, the anti-downgrading requirements would apply to any No. 2 15 ppm highway diesel fuel usedfor blending. If the finishedfuel usedfor blending was designated as something other than 500 ppm or 15 ppm highway diesel fuel, then the special provisions described above only apply to that fraction of the volume of the final fuel blend derivedfrom transmix. For example: If 80,000 gallons of transmix was blended with 20,000 gallons ofpreviously certified 500 ppm diesel fuel designated as nonroad, locomotive, and marine (NRLM) diesel fuel, then only 80,000 gallons of the finishedfuel blend could be designated as 500 ppm highway diesel fuel. The remaining 20,000 gallons could be redesignated as NRLM diesel fuel (or heating oil). If the transmix was blended with a blendstock, and not previously designatedfuel, then that fraction of the finished blend attributable to the blendstock would be subject to the standards applicable to refiners (e.g. 80/20). We believe that the above discussion addresses the questioner's concern about the ability to manufacture 500 ppm diesel fuel from transmix. Furthermore, there will be outlets for diesel fuel produced by transmix processors that does not meet a 500 ppm sulfur specification during the time period when the highway diesel produced by transmix processors is subject to a 500 ppm sulfur specification. Such fuel may be sold into the NRLM market or into the heating oil market. 2.9: Will a terminal have to wait for lab results before it can ship product to the rack or another pipeline? A: A terminal acting merely as a distributor or carrier is not required to wait for lab results before shipping diesel fuel. The regulations provide that, like other downstream parties, to establish a defense to presumptive liability a terminal must have a quality assurance program that includes sampling and testing, as one element of its defense to presumptive liability. 2.10: Very few truckstop operators have the ability to carry two grades of diesel fuel. The industry is not likely to install new tanks/lines/pumps for a four year phase-in period. Is there a minimum amount of each product that a marketer must carry and sell to qualify for the 20% downgrade exemption? A: If a retailer makes 15 ppm diesel fuel available to its customers in a manner consistent with the way it markets other fuels, then the retailer is not subject to the anti-downgrading requirements for highway diesel fuel. Typically, this would mean that the retailer would need to provide a fuel pump (or, pumps) and have sufficient volumes of 15 ppm highway diesel fuel available so that end-users wishing to purchase 15 ppm diesel fuel do not find it significantly more difficult to refuel than customers who wish to refuel with 500 ppm diesel fuel. 14 ------- 2.11: At retail locations, will the diesel dispenser have a different size nozzle to prevent a customer from misfueling? A: EPA did not require unique dispenser nozzles for 15 ppm diesel fuel. This is something we considered on several occasions, but concluded, after discussions with the relevant stakeholders that misfueling would not likely be significant enough to justify the cost and burden of the vehicle andfuel pump changes. The nonroad diesel rule includes labeling requirements for fuel dispensers and vehicles to help prevent misfueling. The fuel dispenser labeling requirements finalized in the highway diesel rule were superceded by those in the nonroad diesel rule (see 40 CFR 80.570, 80.571, 80.572, 80.573, & 80.574). 2.12: From an end-user viewpoint (trucking company): a) What is the liability in the event of misfueling by a driver? b) What effect does running ULSD in older equipment have on the engine? c) What is the impact of running 500 ppm fuel in a new (2007+) engine? d) Will companies with bulk fuel for use in their own equipment be subject to testing? e) Will existing tanks currently containing 500 ppm fuel be suitable for storage of ULSD? will tanks need to be purged and cleaned will company need to install new tanks to segregate fuels until 500 ppm is gone? A: a) See question 12.1. The trucking company is liable for misfueling but will be able to meet defense if it can demonstrate that the violation was not caused by the fleet operator or its employees (e.g., fueledfrom a retail pump labeled as containing the appropriate fuel for the vehicle) and, if it is from the company's own pump, it also needs to show PTDs account for the fuel and show it was compliant. b) Generally, ULSD will be beneficial to engine operation and durability. The only known concern is with the lubricity of ULSD, which will be ensured through the use of lubricity additives to the fuel. ASTM has adopted a lubricity spec for diesel fuel to assure proper fuel lubricity. c) If a new (MY 2007 or later) truck is misfueled once, it will have significantly higher PM emissions during operation on that fuel, but there should not be any significant long-term emissions or engine durability concerns as long as the vehicle is then fueled with the proper fuel. Constant misfueling would damage the after treatment/emission controls on these newer vehicles. d) EPA will inspect wholesale purchaser-consumer facilities and take samples from fuel pump stands andfrom vehicle fuel propulsion tanks. e) ULSD can be stored in tanks currently storing other fuels, including 500 ppm fuel and high sulfur fuel. However, care must be taken when 15 ------- transitioning the tank to avoid contamination of the ULSD. If a rapid turnover is desired, purging and cleaning the tank is an option, however it is not required. 2.13: It could take several loads of 15 ppm to flush out a retail tank, and this could take several weeks. Is there a provision for downgrading the product during this transition? A: Yes. During the start of the program, the anti-downgrading provisions do not start until October 1, 2006 (see § 80.527(c)(3)), allowing for a normal orderly transition. Even after October 1, there is an allowance for 20% to be downgraded. Since contamination at retail after the transition is expected to be minimal, 20% over the course of the entire compliance period should be sufficient. 2.14: Regarding the 2 ppm adjustment factor- this applies downstream of the refinery and the import location. Assuming a terminal has a single ULSD storage tank that receives product from a refinery and also receives ULSD imports, both receipts would be designated as 15 ppm on-highway diesel and would otherwise be fungible. Would this tank be a downstream tank or an import tank? Would the 2 ppm adjustment factor apply to this tank or not? A: As in other fuels programs, tanks downstream from the certification tank will generally be considered "downstream " tanks and will be eligible for the 2 ppm test result adjustment, per § 80.580(d). However, this would not be the case if a company uses a tank as a downstream tank for refinery purposes and also uses it as a certification tank for its imports. In such a case the tank would not be eligible for the 2 ppm adjustment. 2.15: What are the recordkeeping issues related to biodiesel used as lubricity additives for ULSD? A: Recordkeeping in this case will be the same as any other blending component. If the biodiesel provider designates the fuel as MVNRLM, then he serves as the refiner. If the provider does not designate, then the blender serves as the refiner. 2.16: In order to be in compliance with the lubricity requirements of the ASTM D 975 diesel fuel specification, refineries will have to use lubricity additives, some of which may contain sulfur. Most, if not all, pipelines will likely prohibit the use of these additives in product that they transport. Therefore, these additives will be added to diesel fuel downstream of the pipelines (either into tanks at the terminal or at the rack). Can volumetric calculations be used to account for the sulfur content of these additives? A: No, volumetric calculations cannot be used to account for the sulfur content of these additives. 16 ------- 2.17: During the initial phase, I deliver 15 ppm fuel to a customer. The product is contaminated (and, as a result, no longer meets the 15 ppm standard) while in his custody. The customer then ships the fuel back to me due to its contamination. Upon receipt of the fuel, I reclassify it as 500 ppm- does this count against my 20% downgrade? A: The owner of the facility where the contamination occurs is responsible for redesignating off-spec fuel, andfor accounting for it in its compliance calculations. The product that is shipped back to your facility must be appropriately designated and the product transfer document must reflect this designation. When the product is returned to you, it should already be designated as 500 ppm (since the party that caused the contamination is responsible for redesignating fuel that no longer meets the applicable standard), so you would not have to reclassify/redesignate the fuel and the downgrade would not count against your balance. 2.18: 50,000 bbls of 15 ppm is discharged from an on-spec vessel. On the way to the tank, it became contaminated via pipeline. The receiving tank had 20,000 bbls in it, and the 50,000 bbls of contaminated fuel is put on top of the 20,000 bbls. What is charged against the terminal's 20% rule if it is redesignated as 500 ppm highway fuel? A: Volumes are calculated based on receipts and deliveries for each custody holder. In this hypothetical situation, there would be 70,000 bbls of fuel designated as 15 ppm highway fuel received by the terminal, but 70,000 bbls of500 ppm highway fuel delivered. (See 40 C.F.R. § 80.527(d).) This assumes that the 50,000 bbls of fuel was in the custody of the terminal when the contamination occurred in piping. 2.19: Must diesel fuel treated as blendstock (DTAB) be off-spec, or can it be on-spec and "treated" as blendstock? A: The DTAB provisions of § 80.512 may be used regardless of whether the diesel fuel is "off-spec." 2.20: The 20 percent downgrade restriction in the highway rule is going to be extremely tight the second half of 2006 in large part due to refining production only being required 3 months in advance of retail sales and the first year being a partial year for the downgrade standard and, most critically, this is the first year for tank transition with a lot of higher sulfur distillate in the system. Many are planning on just in time delivery of ULSD from the refineries which means transportation will be faced with considerable downgrade during the transition period that limit downgrade to the on-road market to 20 percent. While no retailer is required to sell ULSD, anyone that handles ULSD may not downgrade more than 20% of the net volume received in any year into the on-road pool. This is likely to be a problem, especially for those moving small batch volumes. EPA 17 ------- needs to delay the start date of the downgrade limit period or get rid of it all together for this first year. Alternative, if all else fails, they should group the period with 2007. A: As finalized in the nonroad rule, the start of the first compliance periodfor anti- downgrading was delayed to Oct 1, 2006 to allow for the expected downgrade during the initial transition to ULSD. The compliance period was also lengthened to end on May 31, 2007, allowing a longer period over which compliance can be averaged. 2.21: If a pipeline does not have sufficient storage capacity for all grades of ULSD and exempted product, will the pipeline be allowed to blend at the terminal to prevent outages? A: Yes, pipelines/terminals may blend different grades offuel subject to the anti- downgrading limitations on highway ULSD and volume balance requirements for highway diesel fuel, nonroad diesel fuel, and high sulfur NRLM as applicable (see section 80.599). 2.22: Please comment on the possibility of elimination of the red dye requirement for off-road diesel with the introduction of 15 ppm highway fuel and allowing 500 ppm "non-road" diesel to be shipped undyed as it leaves refining gate (to allow the distributors system to accommodate 3 grades of diesel)- please confirm that off-road diesel meeting the 500 ppm requirements may be commingled with 500 ppm on-road diesel? Dye removal, and the ability to commingle will greatly reduce the strains on limited tankage and will add needed flexibility, thereby reducing potential distribution and supply disruptions. Dyeing of "non-road" diesel would take place at terminal rack. A terminal could then handle 15 ppm highway, 500 ppm highway, and 500 ppm nonroad with two tanks common in terminals today. It would also help pipeline companies. Also, can 500 ppm off-road diesel be redesignated as 500 ppm on-road diesel? If so, are there any limits or special testing or documentation requirements? A: While it does not eliminate the red dye requirement for nonroad diesel fuel, the nonroad diesel rule's designate and track provisions (D&T) allow diesel fuel with similar sulfur levels to be commingled andfungibly shipped up to the point of distribution from a terminal, where NRLM must then be dyed. 500 ppm diesel fuel designated as NRLM can be re-designated as 500 ppm highway diesel, but it is subject to the limitations stated in §§ 80.598 and 80.599. 2.23: Could a fleet operator that owns and uses only pre-model year 2007 motor vehicles indefinitely use 500 ppm highway diesel fuel? Even after 2010? What if the fleet operator also produces his own motor vehicle diesel fuel? A: The regulations at § 80.500(d)(4) state that beginning December 1, 2010 the sulfur content standard of § 80.520(c) (i.e., the 500 ppm sulfur standard) shall no 18 ------- longer apply to any motor vehicle dieselfuel. After, December 1, 2010 all motor vehicle diesel fuel must be 15 ppm or less. The regulations at § 80.530(b) state that after May 31, 2010, no refiner or importer may produce or import motor vehicle diesel fuel subject to the 500 ppm sulfur content standard. 2.24: A refiner certifies all of its kerosene as dual Jet/No. 1 diesel at 15 ppm, and counts that volume as 15 ppm motor vehicle diesel fuel and accounts for it in the 80/20 TCO. If all the kerosene is then "downgraded" to Jet fuel, so none of it is available as 15 ppm motor vehicle diesel fuel, is the refiner still complying with the 80/20 rule even though none of the fuel is available as onroad diesel? A: If a refinery designates kerosene as motor vehicle diesel fuel, then sells the kerosene as commercial jet fuel, then the reclassified volume of kerosene is not subject to any downgrading limitation, and does not impact compliance with the 80% 15 ppm diesel fuel production requirement for the Temporary Compliance Option. 2.25: Terminal operators who import product from abroad are in most instances responsible for compliance with the highway diesel fuel rule. These importers understand that if a cargo of on-highway diesel fuel enters the U.S. and does not comply with the 15 ppm standard, they can choose to blend the product to specification if it is possible. These importers would then designate the product as compliant when it leaves the terminal gate. Would EPA please confirm this interpretation. A: The nonroad diesel rule does contain a provision allowing importers to blend near-compliant diesel fuel containing slightly more than 15 ppm sulfur with diesel fuel containing less than 15 ppm sulfur to produce a compliant blend containing less than 15 ppm sulfur- this fuel may then be designated as "diesel fuel treated as blendstock", or DTAB (see § 80.512). 2.26: If a terminal imports off-spec kerosene (higher than 15 ppm), terminal operators are planning to blend the kerosene with diesel fuel so that the ultimate diesel fuel leaving the terminal gate and entering into commerce meets the 15 ppm standard. Would EPA please confirm that this process is permissible for an importer? A: The regulations at § 80.525 (d) state that kerosene that a kerosene blender adds, or intends to add, to motor vehicle diesel fuel subject to the 15 ppm sulfur standard must meet the 15 ppm sulfur standard. However, under § 80.521 (b), kerosene containing more than 15 ppm sulfur may be blended into motor vehicle diesel fuel at concentrations of one volume percent or less, provided the sulfur concentration of the resulting blend does not exceed the 15 ppm sulfur standard. The accompanying PTD must also accurately reflect this. 2.27: Refinery shipments by pipeline often occur with the producing company retaining title to 19 ------- a volume of product in the pipeline, while the pipeline actually has custody of the product. In this instance, do both the title holder and the custody holder have separate 20% downgrading potentials, or do they share a common 20% downgrading potential? How does one determine who accepts responsibility and reporting for a downgrade that may occur, such as pipeline interface, when the producing company may have title to the product, but the pipeline has custody? A: As clarified in the nonroad rule regulations, the 20percent downgrade limitation applies separately to each facility that has custody of the fuel when it is downgraded. The downgrade provision allows each party in the distribution system that is subject to it to downgrade a maximum of 20 percent of the highway diesel fuel for which it has custody on an annual basis. The downgrade limitation was incorporated to protect the availability of 15 ppm diesel fuel at the beginning of the highway diesel program. Actual contamination and downgrade is expected to be far less than 20%. However, 20% was selected to cover even the worst case scenario. 2.28: In situations where custody changes to/from related entities (such as Company A refinery to Company A Pipeline to Company A Marketing), are these related entities each entitled to a 20% downgrade? Or, since they are related, are they viewed as one entity and therefore entitled to one overall 20% downgrade? A: As defined in the regulations with the nonroad rule, a downgrade is accountedfor on a facility-by facility basis. Flexibility was included in the rule to allow aggregation of facilities at industry's discretion subject to certain restrictions (see § 80.502(b). 2.29: A downgrade occurs only when the designation of a motor vehicle diesel fuel is changed from 15 ppm to 500 ppm. A change in designation to any other product, such as jet fuel, home heating oil, No. 4 diesel, is not a downgrade? A: Correct. For the purposes of these requirements, "downgrade " refers to redesignating 15 ppm motor vehicle diesel fuel to 500 ppm motor vehicle diesel fuel. (See § 80.527(a)). Changing the designation of 15ppm motor vehicle diesel fuel to any fuel that is not motor vehicle diesel fuel is not a downgrade, and is not volume limited. 2.30: A "retailer" is limited to a single 20% downgrade of 15 ppm highway diesel fuel to 500 ppm highway diesel fuel unless the "retailer" offers for sale both 15 ppm and 500 ppm highway diesel fuels? Is the term "retailer" intended to apply on the individual service station or truck stop level, or does "retailer" potentially apply to a grouping of related retail outlets, such that if any one of the outlets offers 15 ppm diesel fuel, all outlets could freely downgrade 15 ppm highway diesel fuel to 500 ppm highway diesel fuel? 20 ------- A: Since the downgrade provision was intended to protect availability of 15 ppm highway dieselfuel, a retailer or wholesale purchaser-consumer who sells, offers for sale, or dispenses either only 15 ppm motor vehicle diesel fuel or 15 ppm and 500 ppm simultaneously throughout the calender year is exempt from the 20 percent downgrading limit. A retailer or wholesale purchaser-consumer who does not sell, offer for sale, or dispense 15 ppm motor vehicle diesel fuel can downgrade 15 ppm diesel in an amount no greater than 20 percent of the total volume of motor vehicle diesel fuel it sells, offers for sale or dispenses annually. The limitation applies separately at each facility. Only contiguous facilities can be aggregated. 2.31: We understand that during the period the temporary compliance option is in effect, a party will base compliance with the 20% downgrade requirement on the incoming and outgoing PTD records. Is the "incoming PTD record" reflective of the bbls input onto a pipeline or the bbls received at a terminal? A: These provisions were clarified in the regulations finalized with the nonroad rule. Specific answers can be found at § 80.599 (e). Calculations are based in all cases on volumes received into the facility and volumes delivered. 2.32: In the situation where a refiner owns and operates a proprietary pipeline, can 20% of the pipeline movements be downgraded as provided by § 80.527 (c)? If a third party operates the pipeline, can 20% of the pipeline movements be downgraded as provided in § 80.527(c)? A: As long as the pipeline is registered as a separate facility, the anti-downgrading limitation applies to it regardless of ownership. If the proprietary pipeline were aggregated into the same facility as the refinery, then the anti-downgrading regulations would not longer apply. Rather, the refiner's production would be based on the volumes deliveredfrom the pipeline. 2.33: If a refiner annually ships 100 units of diesel (20 units of 500 ppm diesel, 80 units of 15 ppm diesel) and the pipeline moves 3 units to 500 ppm diesel as interface, the terminal receives 23 units of 500 ppm diesel and 77 units of 15 ppm diesel fuel. Is the terminal now allowed to downgrade 16 units (20% of 80 units) or 15.4 units (20% of 77 units)? A: Each party in the distribution system is subject to the 20 percent downgrade limitation based on the amount of 15 ppm fuel for which it has custody on an annual basis. Therefore, if the terminal only receives 77 units of 15 ppm sulfur fuel. It may downgrade up to 20 percent of the 77 units of 15 ppm fuel for which it has received custody to 500 ppm highway diesel fuel. 2.34: Is there some limitation for how long or when a retailer must sell the 15 ppm highway diesel before they would fall under § 80.527(e)(2) as opposed to § 80.527(e)(1)? 21 ------- A: Retailers or wholesale purchaser-consumers who sell only 500 ppm motor vehicle dieselfuel are subject to a downgrade limitation such that a maximum of 20 percent of the total volume of motor vehicle diesel fuel that they sell on an annual basis can be composed of downgraded 15 ppm fuel. Under § 80.527(e)(1), retailers or wholesale purchaser-consumers who sell, offer for sale, or dispense 15 ppm motor vehicle diesel fuel are exempt from the 20 percent downgrade restriction. This includes parties who sell only 15 ppm, or sell both 15 ppm and 500 ppm simultaneously. To best promote the purpose of the downgrade requirements, which is to account for contamination without interfering with widespread availability of 15 ppm highway diesel fuel, the exemption only applies to retailers or wholesale purchase-consumers that sell, offer for sale, or dispense 15 ppm fuel continuously throughout the year beginning January 1 (or for 2006, September 1). "Continuously " here is meant to include normal business practices, including short shut downs for repairs, or delays in sales based on delivery problems. If at any time during an annual compliance period (calendar year) a retailer or wholesale purchaser-consumer ceases to sell 15 ppm, he/she would be subject to the 20 percent downgrade restriction of § 80.527(c) over the remaining portion of the compliance period. 2.35: § 80.527 restricts the flexibility of all parties in the 15 ppm highway diesel fuel distribution system to downgrade 15 ppm highway diesel fuel to other classifications. Is it correct that retailers can choose to downgrade all, or a portion, of the 15 ppm diesel fuel delivered, provided it is properly labeled and sold? A: The downgrade limitation was incorporated into the highway diesel program to protect the availability of 15 ppm highway diesel fuel at the beginning of the program. If distributors and retailers purchased 15 ppm highway diesel fuel in large quantities and sold it as, or mixed it with 500 ppm fuel, assurance of the availability of 15 ppm highway diesel fuel would be compromised. If retailers are selling only 15 ppm highway diesel fuel, they are by definition not selling 500 ppm fuel and the provisions do not apply. If retailers are simultaneously selling both 15 ppm and 500 ppm highway diesel, they are still satisfying the needfor 15 ppm availability and thus, we chose not to apply the downgrade limitation to them as well. Only retailers who are not selling any 15 ppm highway diesel fuel (that is they are only selling 500 ppm fuel) are subject to the downgrade provisions such that of the total volume of motor vehicle diesel fuel that they sell in a year, only 20 percent of it may come from 15 ppm supplies. 2.36: The rule states that 15 ppm highway diesel fuel found in violation of the 15 ppm standard will be credited toward the 20% downgrade volume allowance. Could this fuel be downgraded to off-road usage and not count toward the 20% downgrade allowance? 22 ------- A: If fuel originally designated as 15 ppm motor vehicle diesel fuel subsequently does not meet the 15 ppm standard, it can be either: 1) redesignated as 500 ppm and counted toward the 20 percent downgrade limit for 500 ppm motor vehicle diesel fuel, or 2) redesignated as NRLM diesel fuel (in unlimited amounts). 2.37: Could 500 ppm highway diesel fuel in excess of the 20% allowable 15 ppm highway diesel fuel downgrade be shipped back to a refiner and avoid a determination that the downgrading entity is out of compliance? A: Compliance is on a facility-by-facility basis. The regulated parties must have redesignated the excess downgraded 15 ppm highway diesel fuel as something other than 500 ppm highway diesel fuel to avoid exceeding the 20% downgrading limit. If it is downgraded and redesignated as 500 ppm highway diesel fuel, then it is a downgrade, even if it is shipped back to the refiner. If it is not re- designated as 500 ppm highway fuel, then it would not count against the downgrade limit. Compliance with the downgrading requirements is on an annual calendar year basis. Any regulated party downstream of the refinery gate may downgrade more or less than 20% of any batch as long as compliance with the 20% downgrade limit is met at the end of the year. 2.38: To allow for the learning curve necessary in a period of transition, would EPA consider a delay in implementing the 20% downgrade rule for pipelines and terminals during the time the distribution system is being converted to 15 ppm diesel fuel, perhaps up until October 1, 2006, recognizing that distributors will have every incentive to minimize the downgrade of 15 ppm diesel fuel given the anticipated product price differential? A: As amended in the nonroaddiesel regulations, § 80.527(c)(3) states that the anti- downgradingprovisions begin on October 1, 2006. 2.39: Can a small refiner who must produce 100% 15 ppm motor vehicle diesel fuel sell downgraded 500 ppm fuel at its refining truck loading rack? A: The nonroad rule modified these provisions to define a refiner's production as the volume delivered to the next entity. To allow for downgrade in the handojf, the production requirement was modified to 95 percent. (This is discussed in the preamble, but was inadvertently left out of the regulations. We intend to correct this error in a future technical amendment to the regulations.) Any fuel produced and certified by another refiner can always be brought in and sold over a refiner's rack. The refiner in this situation must also report and maintain records as a fuel distributor under the designate and track regulations. 2.40: There has been discussion on the "downgrading" provisions. What about upgrading? For example can a terminal operator, marketer or third party earn and sell credits for "upgrading" V500 to VI5? We assume that these do not employ any fractionators, and 23 ------- are not "refiners". A: Only refiners and importers can generate credits per the regulations at § 80.531. 2.41: If both 15 ppm and 500 ppm on-road diesel are both available at a terminal [facility selling wholesale by the transport] is the terminal restricted to downgrading no more than 20% of its 15 ppm onroad diesel to 500 ppm onroad diesel? A: Yes. The regulations at § 80.527(c) state that persons who sell, offer for sale, dispense, supply, store or transport diesel fuel may not downgrade a total of more than 20% of the motor vehicle diesel fuel (by volume) that is subject to the 15 ppm sulfur standard of § 80.520(a)(1) while such person has custody of such fuel. Calculations to demonstrate compliance are found in § 80.599 (e). 2.42: In doing my quality assurance check, I find that my supplier has given me 15 ppm because he was out of 500 ppm. Can I upgrade the product that the PTD's say is 500 to 15? A: Yes. 2.43: Consider the following issue - as a batch of fuel moves down the pipeline, volumes are stripped off of the heart of the batch, since the interface at best stays the same or more likely will grow in length as the batch moves down the pipeline, the volume of material that must be downgraded at the end of the pipeline as a percent of the remaining batch volume will be much larger than at facilities upstream on the pipeline. The concern is that facilities at the end of the pipeline may have more difficulty in coping with the 20% limit on down grading, on a facility-by-facility basis. A: The 20% downgrade limitation applies separately to each facility in the distribution system. Facilities at the end of the distribution system only need to comply based on the volumes of 15 ppm fuel that they receive. Any downgrade that occurs upstream does not enter into their compliance calculations. 2.44: Terminals have no financial incentive to downgrade product from 15 ppm to 500 ppm. However, there is concern about contamination and the 20 percent downgrade limitation, particularly within the first several months following implementation. Will EPA issue a technical amendment that would allow the industry to downgrade the 15 ppm product without limitation, or at least remove the limitation for the first six months of the program. A: EPA believes we have allowed terminals adequate lead time to identify and correct potential sources of contamination for 15 ppm diesel. The 20% downgrade limitation is on an annual basis, so if a terminal has to downgrade more than 20% of its 15 ppm diesel at the beginning of the program, it has the 24 ------- opportunity to compensate for downgrades greater than 20% by downgrading less of its 15 ppm highway diesel later in the year. Further, the anti-downgrading provisions do not begin until October 1, 2006, in order to allow for a normal transition at the start of the program. 2.45: Question 2.35 deals with restrictions on the flexibility of all parties to downgrade 15 ppm motor vehicle diesel fuel to other classifications. If a small terminal has its supply of 15 ppm fuel contaminated with 500 ppm fuel, how much can the marketer use of that contaminated fuel that the terminal has downgraded to 500 ppm? Our interpretation of the rule is that the marketer handling 500 ppm can get only 20% of his 500 ppm supply from downgraded 15 ppm. Is this correct? A: The regulations at § 80.527(c)(3) state that the 20% downgrading limitation shall be on an annual or compliance period basis. The terminal may sell all of the contaminated batch as 500 ppm fuel provided that the terminal's total annual downgrade percentage for the compliance period does not exceed 20%. This fuel would now be designated a 500 ppm by the terminal. As such, anti-downgrading provisions would no longer apply to it for any marketers that received it. 25 ------- 3. Analytics R&D Issues/Test Methods 3.1: What rounding convention will be used for sulfur content tested by EPA? A: The sulfur specification is 15ppm. Standard rounding conventions apply. For example, a measurement of 15.49 would be rounded down to 15 ppm. 3.2: The regulations at section 80.580(c)(1) include the following: "...is correlated with the appropriate method specified in paragraph (a)(2) of this sectionIs "(a)(2)" incorrect? Should it be "(b)(1)" which references ASTM D 6428-99? A: Yes, the current citation in the regulations is incorrect. It should be "(b)(1). " EPA intends to correct this in a subsequent technical amendment rulemaking. 3.3: The regulations at section 80.580(c)(1) include the following: "...is correlatedwith the appropriate method specified in paragraph (a)(2)(H) of this sectionIs "(a)(2)(ii)" incorrect? Should it be "(b)(2)" which references ASTM D 2622-03? A: Yes, the current citation in the regulations is incorrect. It should be "(b)(2). " EPA intends to correct this in a subsequent technical amendment rulemaking. 3.4: ASTM and ISO frequently update their test methods; must an EPA approved method be resubmitted to the EPA for approval if the modifications to the test methods (that are made by ASTM and ISO) are minor and have no significant impact on the accuracy and precision of the method? A. All EPA approvals are specific not only to a given test method and laboratory, but also to a particular version of that test method. Thus if ASTM or ISO released a revised version of a test method, any EPA approvals for previous versions of that same test method would remain valid and laboratories could continue to use the previous version. If the laboratory intended to use the revised version of the test method, formal approval must be sought from the EPA. EPA is exploring procedures in the context of the current regulations under which a revision to a specific test method could be deemed inconsequential to its accuracy and precision. If such a procedure can be developed, EPA may be able to permit the qualification for the old version of a test method to apply also to the new version of that test method. 3.5: Must a third party independent lab be "registered" with the EPA to get test methods approved? A: Under §§ 80.584 and 80.585, each lab that will be testing fuel for compliance with the diesel regulations must obtain EPA approval on a laboratory-specific 26 ------- basis. The information requiredfor approval is somewhat different depending on whether the test method is one that has been approved by a voluntary consensus- based standards body. However, there is no independent laboratory registration per se, as there is under the RFG program under § 80.65. 3.6: Are the EPA approved test methods for diesel automatically approved for use on kerosene or heating oils, or must the test method be approved for each product? A: EPA does not require testing on heating oil. Consequently, there is no need to seek approval from EPA regarding the method usedfor the testing of heating oil properties. Any testing on #1 diesel fuel (kerosene) used in highway diesel or diesel nonroad, locomotive, or marine engines required by EPA must be conducted using an approved test method. The test methods approved by EPA for testing of the properties of #2 diesel fuel are also applicable for the testing of #1 diesel fuel. 3.7: Under the performance-based test method approach adopted in the non-road diesel sulfur rule, there is no designated sulfur test method as has been specified in previous regulations. Methods developed by consensus bodies, as well as methods not yet approved by a consensus body, qualify for approval provided they meet the specified performance criteria, as well as the recordkeeping and reporting requirements for quality control purposes. The rule specifies the precision and accuracy criteria that a laboratory must demonstrate in order to qualify its particular method of choice. API believes that the EPA enforcement lab should be required to meet or exceed the precision and accuracy criteria imposed on industry and that this should be a prerequisite to pursuing any enforcement action on a fuel parameter. Does the EPA Ann Arbor laboratory also need to demonstrate that its sulfur method(s) of choice meets the precision and accuracy criteria in the rule and maintain records for quality control purposes? A: The EPA lab in Ann Arbor currently performs testing offuel samples for enforcement purposes. EPA fully anticipates that its laboratory will have the capability to run several different test methods meeting the precision and accuracy criteria specified in the rule. However, whether we meet these criteria or not, is not a "prerequisite " to pursuing any enforcement action. Per section § 80.611 evidence can be used in assessing whether a violation has occurred. Uncertainty in our own test results is just one of the factors that would go into any decision to take enforcement action. 3.8: Will EPA test terminals or retail outlets? A: EPA conducts sampling and testing offuel at all points in the distribution system. 3.9: A batch of diesel is produced, sampled and tested on the last day of the reporting period but it is not shipped for several days until the next reporting period. With gasoline, the 27 ------- production date is used as the reporting basis. Should the diesel batch be reported as part of the earlier compliance period or alternatively as the "production" date which is the date of shipment from the refinery? A: Under the ULSD regulations as finalized in the nonroad rule, a batch of diesel fuel is defined as homogenous product that has been transferred to the next facility in the distribution system. Consequently, the only batches of fuel that should be reported are those that are transferred during the compliance period to another facility. 3.10: Can early release ULSD (prior to June 2006) be certified using designated or alternative methods, or must a PBMS qualified method be used? A: If the refiner wishes to certify it as 15 ppm fuel and obtain early credits, it must follow the PBMS requirements. For ULSD, the use of the designated and alternative test methods expired on 12/27/2004, so the only way to measure 15 ppm sulfur diesel fuel is by using a method that meets the accuracy and precision criteria at 40 C.F.R. 80.584 and is approved under the procedures set forth at 40 C.F.R. 80.585. 3.11: Performance-based laboratory qualification misses the sampling piece of the equation. D4057 allows several methods for manual sampling of tanks, if the method is not specified then the results can be unrepeatable. Will the sampling method be specified by the analytical methods? A: No. The sampling method used under D4057 will be at the user's discretion. 3.12: Will EPA consider allowing the volume accounting reconciliation (VAR) approach with lubricity additives greater than 15 ppm sulfur? A: We have no intent to do so. The VAR approach was developedfor the specific situation of conductivity improver additives where no additive option existed with less than 15 ppm sulfur and the additive was required to be added at the terminal. 3.13: The nonroad rule does not explicitly exclude on-line sulfur analyzers for certification purposes; and industry plans to utilize on-line analysis that meets EPA's rule for precision and accuracy. Can on-line sulfur analyzers be approved for certification purposes if they meet the precision and accuracy criteria stated in the regulatory requirements, and if not, why not? Section § 80.581 (c)(1) allows the use of on-line analyzer test methods that have been approved per section 80.580. However, sections §§ 80.580 and 80.585 do not reference on-line analyzers; do these sections apply to on-line analyzer approval as well, or does the EPA plan on issuing separate procedures for on- line analyzer approval? 28 ------- A: The intent of § 80.581(c)(1) was not to imply that on-line analyzers could be used to certify a batch of dieselfuel. § 80.581(c)(1) states the dieselfuel batch's composite sample must be tested with a test method as described under the provisions of § 80.580. The purpose of the provision is to provide the flexibility to refiners to release a batch of diesel fuel prior to that batch's composited sample being tested with a test method that: 1) is described under 80.580, 2) meets the accuracy and precision criteria described under § 80.584, and 3) is approved under § 80.585. The test method that meets these three criteria on the composited sample of the batch is the official test result. In order to allow for the release of the batch of fuel prior to the composited sample being tested, we believe it is necessary to require that on-line analyzers meet the accuracy and precision requirements of § 80.584 and are qualified under the process of § 80.585 (see also § 80.581(c)(1)). The Agency believes a regulation change would be required to allow on-line blending systems (including on-line analyzers) to certify batches of diesel fuel. However, before this issue could be addressed in a rulemaking, the Agency believes that, at the very least, the following concerns would need to be addressed: 1) Acceptable extent of intra-batch variability during the course of a blend; 2) Appropriate statistical demonstration of blending system's ability to closely track results from bench analyses of composite samples; 3) Nature of on- going statistical quality control of blending process needed to ensure that measurement quality is maintained; 4) Nature of recordkeeping and EPA access needed to permit audit oversight; and, 5) Size limits on batches. 3.14: Section 80.581(c)(1) appears to require composite sampling/testing even though an approved on-line analyzer method is used during blending. If this is true, why must the on-line analyzer method be approved if the analyzer results are not used for compliance purposes? Will the composite testing and reporting requirement be waived if the on-line analyzers are approved? Will EPA consider on-line analyzer results as evidence in establishing a defense in enforcement actions? A: Yes, § 80.581(c)(1) does require that a composite sample of a diesel batch be taken, and the composite sample is required to be tested with a test method described under § 80.580, which meets the accuracy and precision criteria under § 80.584 and is approved under the process at § 80.585. But the intent of § 80.581(c)(1) was only to provide flexibility to refiners that utilize on-line analyzer equipment so they could release a batch of diesel fuel prior to its composited sample being tested by a test method described under § 80.580. In order for a refinery to have the flexibility to release a batch of diesel fuel prior to its composited sample being tested with a test method described under § 80.580, § 80.581(c)(1) does require that the on-line analyzer must meet the applicable accuracy and precision under § 80.584 and be approved under the process at § 80.585. This is to help ensure that the diesel fuel leaving the refinery is compliant 29 ------- with the applicable standard. Thus, on-line analyzer approval is required if a refinery wishes the flexibility of releasing a batch of diesel fuel prior to that batch of diesel fuel's composited sample being tested by an approved test method under § 80.585. Thus, EPA will not consider on-line analyzer test results as meeting the requirement for refiners to test each batch of diesel fuel designated as 15 ppm fuel. 3.15: Given the results of the recent ASTM round robin testing comparing the repeatability and reproducibility of the designated ASTM 6428 sulfur test and the alternative ASTM 5453 test, will EPA reconsider the issue and define the more precise ASTM 5453 test method as the designated sulfur test method? A: The regulations finalized with the nonroad rule modified the sulfur test method requirements. Instead of a designated method, there are now simply performance-based requirements that must be met, allowing the use of multiple test methods (see § 80.580 and 69 FR 39184). 3.16: Given the reproducibility of even the most precise sulfur test method is no better than 6 ppm, will EPA revise the 2 ppm enforcement test tolerance? A: We believe that a small minority of the labs which have not yet taken steps to improve their measurement procedures are the cause of continuing poor reproducibility results. Once these labs take the steps to meet the accuracy and precision criteria required in the regulations, their result should improve considerably. We have asked API and NPRA to actively work with these labs and offer our lab to anyone seeking assistance or wishing to compare test results. 3.17: If in general pipelines can demonstrate that the percentage of sulfur tracks with gravity, or sound velocity, or color, will that be a sufficient defense that the pipeline did not contaminate a batch (assuming the pipeline can show what readings were when the valve change were made)? Or will the pipeline need to have a lab analysis, go/no go test, or on-line sulfur analyzer to defend? The treatment of pipeline interface will be important to pipeline operations and the impact of 15 ppm diesel fuel implementation on fuel supplies. A: The rule does not specifically require that pipelines use on-line sulfur analyzers for quality assurance purposes. However, use of on-line analyzers may be appropriate at certain locations on the pipeline. To ensure that the diesel fuel meets the 15 ppm standard, the quality assurance program must include testing, and at this time EPA believes such testing must measure the actual sulfur content of the fuel. However, other relevant procedures that, for example, help a pipeline to locate an interface, could also be an important part of the quality assurance program for a pipeline. 30 ------- The rate of sampling and testing, and where product should be sampled, are a function of the circumstances attendant to a particular distribution system. The pipeline should use its knowledge of the system and exercise its best professional judgment in determining the rate of sampling and testing and where samples should be taken. Also, pipelines may act cooperatively with upstream and downstream parties to share their testing information as part of the pipeline's quality assurance program. 3.18: Due to the known reproducibility problems in testing at a 15 ppm level, would EPA consider letting downstream entities "average" the sulfur level tests within a range - say no more than 20 ppm maximum and 15 ppm average - to avoid supply disruptions? A: No. As stated in the preamble to the final rule, the sulfur sensitivity of emission controls that will be used on model year 2007 and later motor vehicles requires that the sulfur content of highway diesel fuel dispensed into 2007 and later heavy- duty vehicles not exceed 15 ppm. Consequently, under the rule, the 15 ppm sulfur standard is a cap that must be met on a per-gallon basis. To account for test variability downstream of the refinery gate or import facility, the rule allows a downstream test adjustment of negative 2 ppm. The purpose of taking testing variability into account in compliance determinations for fuel sampled downstream of the refinery or import facility is merely to ensure that fuel actually meeting the 15 ppm cap is not rejected and treated as noncompliant due to concerns about testing variability. It is not expected to result in any increase in the actual sulfur content of highway diesel fuel above 15 ppm at any point in the distribution system. Note however, that the rule does not limit the ability of the fuel distribution industry to set a commercial pipeline sulfur content specification. We acknowledge that pipelines may elect to set sulfur specifications 3.19: If a pipeline or terminal has test results indicating that motor vehicle diesel fuel sulfur content is 15 ppm and EPA tests show the sulfur content is greater than 17 ppm, would the pipeline's tests be an acceptable defense, or would the EPA's test results prevail? This is of concern given the variability in test tolerance experienced during the round robin. A: EPA would treat this as a violation. 3.20: Pipelines require durable, easy-to-use test equipment that can quickly give test results. We have been fortunate to find equipment that meets our needs in time for past rule implementations. The EPA's field testing practice has been to use the same equipment pipelines use to conduct oversight. What are EPA's plans on field oversight in implementation of this rule, and has the EPA made any selection of equipment that will be used in the field? 31 ------- A: EPA does plan to conduct field screening of diesel fuel as well as testing diesel fuel using the designated methodfor enforcement purposes. We have not yet selected a field test instrument. 3.21: ASTM updates test methods every five years. Will EPA issue a ruling that will allow the latest (most up to date) version? A: rule for non-road diesel contains a performance-based provision specifically for diesel sulfur that allows the use of any diesel sulfur test method that meets certain criteria for accuracy and precision. Under this approach, industry would be able to determine on their own whether updated ASTM test methods would be acceptable for compliance testing purposes. 3.22: Accuracy can be compared to a gravimetric standard? Are NIST standards available? A: Several highly accurate standard reference materials (SRMs) are now available from NIST. 3.23: Is sulfur measurement at 15 ppm level practical at the pump? Do any of these methods work for portable/field testing? A: Currently only for sampling at the pump and testing in the lab. Methods may yet develop as they have in the past for other properties for field measurement. 3.23: Low sulfur gasoline test method is D-2622[WDXRF], low sulfur diesel will be tested by D-6428 [5453 alternate]. Is there a chance that both test methods could be merged so that one test method for both low sulfur gasoline and diesel would be permitted? A: The Agency has adopted a performance based test method approach which would set forth criteria to determine the acceptability of use of voluntary consensus standard based analytical test methods. Under this approach, industry would be able to determine whether test methods allowed under the low sulfur gasoline rule may also be utilized under the low sulfur diesel rule. 3.24: If 15 ppm is required in the retail market, what will be the pipeline requirement for sulfur at the refinery gate? A: EPA estimated that, on average, 7-8ppm sulfur would be needed the refinery gate in order to produce 15 ppm sulfur at the pipeline's end (see the highway diesel rule Regulatory Impact Analysis, section V.C.I.a for additional discussion). Sulfur contamination during pipeline transport will vary between distribution networks, and therefore refinery production sulfur levels can vary as well. 32 ------- 3.25: Terminal operators currently marketing ultra low-sulfur diesel fuel (15 ppm) are concerned about the accuracy of the equipment available today in the field for testing. Will EPA recommend which equipment industry should use for testing? What equipment has the Agency decided to use to determine compliance? A: Presently we are utilizing several different instruments in our lab. We will use whatever instruments over time we believe provide the best result. 33 ------- 4. Regulatory Clarification and Thoughts/Questions for EPA 4.1: What, if any, grace or discretion will be afforded during start up of the enforcement process? A: There are several provisions in the rule that provide flexibility during the transition period. For example, the 20% downgrade limitation is an annual compliance period requirement, such that any start up difficulties can be offset later in the year. We also allow a 2 ppm downstream test adjustment on top of the 15 ppm cap. Moreover, the rule provides substantial time periods for parties at each stage of the distribution system to come into compliance during the initial transition into the sulfur programs. Hardship provisions that are available to qualifying refiners and importers address cases of extreme hardship or unforeseen circumstances outside the control of the refiner or importer. However, under the "hardship" provisions of the regulations, under no circumstance may fuel having a sulfur content exceeding 15 ppm be sold or dispensed for use in engines requiring 15 ppm fuel. 4.2: The regulations talk about the requirements for PTDs for both the diesel fuel and the additive, but it is unclear at what point an additive PTD is tied to a fuel PTD; i.e. you would never know in which batch a high sulfur additive was used. Are we required to re-certify 15 ppm diesel fuel downstream if an additive with more than 15 ppm sulfur is used downstream of the refinery certification? Are we required to modify the diesel PTD to include language stating that an additive with more than 15 ppm sulfur was used in the product? A: There is no specific requirement to tie additive PTDs to diesel fuel PTDs. Sections 80.521 and 80.591 set forth requirements for additives and additive PTDs. The regulations also set forth prohibitions against selling diesel fuel represented to meet the 15 ppm sulfur standard unless it does meet that standard. The additive blender will be liable if it causes fuel it represents to meet the 15 ppm standard to exceed that standard. For an additive blender who uses an additive having a sulfur content exceeding 15 ppm to meet its defense elements it must, among other things, show that: it did not cause the violation; that product transfer documents account for the product (both the diesel fuel and the additive) and indicate the fuel and additive were in compliance while under the party's control. Also note that § 80.613(d)(2) will require, in most cases, that the blender show that it tested every batch of fuel it blends such additive into. To establish these defenses, the additive blender would likely need to have records that do tie the additive blending to particular transfers offuel. In the case of static dissipater additives, a blender may use a volume reconciliation approach in lieu of every batch testing. 34 ------- 4.3: Is there any economic hardship requirement escape clause for the distribution chain? Given no field testing equipment available, insufficient tankage, commingled manifolds. A: The economic hardship provisions in the regulations only apply to refiners. 4.4: What recourse does a pipeline have that has to receive an off spec batch of ULSD from another pipeline? A: The PTD for any given batch of fuel in the distribution system must accurately reflect the sulfur content of that batch. If a pipeline accepts a batch of ULSD into its system and later finds that the batch no longer complies with the sulfur specification for ULSD, then that pipeline must ensure that the PTD that accompanies the fuel as it leaves the subject pipeline's custody is accurate. If the pipeline finds that the sulfur content of the subject fuel batch is less than 500 ppm, then the pipeline may redesignate that fuel batch as 500 ppm highway diesel fuel (until 6/1/2010) provided that the pipeline remains in compliance with the 20 % downgrade requirements for 15 ppm highway diesel fuel and highway diesel fuel volume balance requirements. The fuel batch may also be redesignated as NRLM, LM, or heating oil provided that sulfur content of the fuel batch is consistent with the applicable sulfur specification. There are no limitations on a downstream pipeline's ability to receive such a batch of fuel. 4.5: What are the provisions from the non-road rule that have been expanded to the highway diesel rule, or that amend the highway diesel rule? A: The nonroad rule final regulations (69 FR 38958, June 29, 2004) identify all the provisions that were amendedfrom the highway diesel rule. Provisions that were changed are specifically noted at the beginning of the applicable section. However, please feel free to contact EPA staff if you have questions on a specific section. 4.6: The regulations require batch reports for small refiners for each compliance period from June 1, 2007 through May 31, 2010 per 80.604(d). For each batch, this includes "the sulfur content and cetane and aromatics content of the fuel" (80.604(d)(5)). This is not consistent with the Agency's response to comments, May 2004, p. 10-32, 10.3.3.3 Aromatics Reporting Requirements. A: The regulations require batch reports for aU refiners. This provision was erroneously copied into the reporting provisions in the regulations. We agree that the batch reporting of cetane index or aromatics levels for off highway diesel fuel is not necessary. The regulations regarding a minimum cetane index of 40 or a maximum aromatics content of 35 volume percent for highway diesel fuel do not include any batch reporting requirements. This is also the case for sulfur content where only the designation is required. We see no need to impose such batch 35 ------- reporting requirements on NRLMdiesel fuel at this time. However, records retained must contain this information. EPA does intend to correct this provision in a subsequent action. 4.7: What provisions exist in the ULSD rules for importing nonroad and highway diesel fuel from Canada by truck? A: Provisions for diesel fuel transported into the U.S. by truck or rail car are found in § 80.583. They are similar to the gasoline sulfur rule provisions for importing gasoline into the U.S. by truck. 4.8: How would distillate not used as fuel (i.e. for freeze protection) be accounted for? A: The possible designations for #1 and #2 distillate are detailed in § 80.598. An entity would have the option to designate it as heating oil or blendstock if it did not want to comply with the highway and NRLM standards. 4.9: For terminal reporting, is it: quarterly reporting with quarterly compliance with 20% downgrade limitation, or quarterly reporting with annual compliance with 20% downgrade limitation? A: Quarterly reporting and downgrading compliance are separate issues. All facilities in the D&T system have quarterly reporting requirements. Truck Loading Terminals also need to provide required compliance calculations. Downgrading calculations are a recordkeeping requirement, not a reporting requirement. The downgrading compliance periods are listed in 80.527(c)(3). 4.10: Current <500 pm kerosene blending into 500 highway diesel is an increase in the highway diesel pool. Is EPA revising § 80.525 to allow for this increase? A: Section 80.525 contains the requirements applicable to kerosene blenders. The provisions regarding the determination of compliance with the volume balance for motor vehicle (highway) diesel fuel are contained in 40 CFR 80.599(b). Each facility must maintain a positive or neutral highway diesel balance during any compliance period. The questioner is correct in that the addition of #1 500 ppm diesel fuel not designated as highway diesel fuel (such as 500 ppm kerosene) to 500 ppm highway diesel could result in an increase in the highway diesel pool. This is possible, but would have to be accounted for in calculating compliance with the facility's highway diesel volume balance. We anticipate that 15 ppm #1 diesel fuel will be available for wintertime blending. The use of such 15 ppm fuel for wintertime blending into highway diesel fuel will not adversely impact the facility's ability to comply with the highway diesel volume balance requirements. 4.11: For consumers with a 2007 vehicle how will they be educated to look for sulfur content 36 ------- at a station to prevent inadvertent use of 500 ppm? A: The fuel regulations require that all fuel pumps be labeled to inform the user which fuel they are dispensing into their vehicle. These labels will state which engines/vehicles that the specific fuel is suitable for use in. There will also be labels on the 2007 engines, per § 86.007-35, stating which fuel should be used. 4.12: Will it be legal for an Alaska refiner to dye its highway ULSD? A: The highway anddieselfuel regulations include no dye requirements or restrictions for Alaskan fuel, provided the requirements of 40 C.F.R. §§ 69.51 and 69.52 are met. IRS has its own fuel tax requirements. 4.13: Has EPA defined the quantitative amount of dye that is visibly dyed? And what does that mean in a lower limit of dye? A: There is no set amount of red dye that must be added to fuel, EPA regulations do not specify what concentration is required. The regulations only require that "visible evidence" of red dye be present (§§ 80.510(d)(5),(e)(5), and (f)(5)), and this amount may vary for different parties. This is the same visible evidence criteria that was first implementedfor non-highway diesel fuel in 1995 (§ 80.520(b)). 4.14: In an effort to maintain balance between nonroad and highway diesel fuel, EPA has established rules pertaining to "shifts" in volume (anti-downgrading). Does this hinder the establishment of new product distributors? A: We do not believe that the volume balance requirements will inhibit the establishment of new product distributors. Any new fuel distributor need only register and then comply for the portion of the compliance period in which they were in business. New distributors would begin with a clean slate with respect to demonstrating compliance with the volume balance requirements. In cases where certain product distribution assets are sold to a new party in the middle of a compliance period, EPA will provide guidance regarding how the previous and new owners will work together to demonstrate compliance for the compliance period in which the sale takes place. One option would be for the original owner to be responsible for demonstrating compliance during the portion of the compliance period during which it maintained ownership. The new owner would then be responsible for demonstrating compliance during the portion of the compliance period over which it exercised ownership. This would be EPA 's default assumption regarding how the applicable requirements would be applied. 4.15: What is EPA's response to the distribution complexities outlined at the workshop? Specifically, if the refiners are not producing ULSD until May 2006, what is EPA's 37 ------- belief that 15 ppm ULSD can be supplied at the pump by September 2006? A: We believe that the rule provides ample time for transition. In most cases, retail stations should have sufficient time to make the transition. However, there is no requirement that retailers must sell 15 ppm ULSD. If their transition takes longer, then they may continue selling 500 ppm fuel longer. 4.16: When may importers begin classifying distillate product as DTAB? A: On the effective date of the regulation. 4.17: Will annual attestation be required for ULSD like it is for RFG today? A: There is currently no attestation requirement in the dieselfuel regulations. 4.18: If the 80/20 provision allows for a 20% downgrade, can we assume that 100,000 bbl ULSD can result in: 80,000 bbl to the pipeline, 64,000 bbl at the terminal, and, 46,000 bbl at retail? A: The volume of 15 ppm highway diesel fuel delivered by a refiner to a pipeline will be reported to EPA based on the measured volume as received by the pipeline operator. In such a case, there would be no downgrade reported in moving the fuel from the refiner to the pipeline. Each custody holder of 15 ppm highway diesel fuel may downgrade up to 20% of the volume it receives to 500 ppm highway diesel fuel. There is no restriction on the volume of 15 ppm highway diesel which can be downgraded to products other than 500 ppm highway diesel fuel (e.g. heating oil, or 500 ppm NRLM diesel fuel). The 20% figure was set because we believed this would be the greatest percentage any one custody holder would need to downgrade due to the procedures necessary to limit sulfur contamination during the transportation of 15 ppm diesel fuel. We expect that most custody holders in the distribution chain will downgrade a much lower percentage of the 15 ppm highway diesel fuel they receive. In most cases economic factors will limit downgrading to the bare minimum. As a result, while the example is hypothetically possible, it is not a realistic scenario. 4.19: Has anyone given any thought as to what the other parameters will look like once ULSD is fully produced (i.e. aromatics, cetane number, nitrogen, etc.)? Are there any issues with respect to the energy content of diesel with the increased hydrotreating potential "lightening" of diesel going down to 15 pm? A: There is a projected change in density and energy content per gallon, thus leading to a small change in fuel economy. In most cases it should be 38 ------- imperceptible- since the change still falls within the range of normal variations in diesel fuel. While fuel economy decreases slightly, there is not an overall energy loss, since refinery production volume increases to offset the energy density change. There is also expected to be a slight improvement in the cetane number of the diesel fuel resulting from a small decrease in aromatic content due to hydrotreating. 4.20: Please explain 20% downgrade provision in detail and specificity- how does it work at each stage in the distribution system, especially if one company plays many roles? A: The anti-downgradingprovision is to prevent the intentional commingling of 15 ppm and 500 ppm fuel that would result in no availability of 15 ppm fuel. The 20% limit is there to allow for unintentional mixing/normal contamination during the compliance period. It works the same throughout the distribution system, with the only exceptions being the unique provisions for retail outlets found in 80.527 (e). Compliance is facility-based, so the fact that a company serves multiple roles does not matter. 4.21: Define "distributor" and "end user" from a reporting and recordkeeping standpoint. A: A "distributor" is any entity in the distribution system — they may or may not be named specifically as a pipeline, terminal, barge, rail system, etc. The activity that the distributor is engaged in will dictate appropriate reporting and recordkeeping requirements. An "end user" as addressed in the presentation, "Recordkeeping and Reporting for NonroadDiesel Fuel", was specifically aimed at recordkeeping requirements for ultimate consumers in Alaska (§§ 80.600(f) & (g) and 80.554(a)(4) & (b)(5)). 4.22: EPA's 2004 refiners' pre-compliance report concludes that there will be an adequate supply of ULSD (at the refinery gates); however, the report does not address the distribution of ULSD. Will ULSD be available in all parts of the country? A: Based on the information that refiners provided in the pre-compliance reports, as well as other discussions, we are confident that ULSD will be available in all areas of the country. Unfortunately, to respect confidential business information, we cannot provide more specific information could not be given in the summary and analysis of the pre- compliance reports on the exact locations that refiners would be producing ULSD. We are currently working on a proposal for a plan for Alaska that will address the unique situation found there. 4.23: Will refiners produce No. 1 diesel fuel at 15 ppm sulfur? What other cold weather-gelling strategies are available to the end-user? 39 ------- A: Yes, some refiners will produce No. 1 diesel fuel. There are also various other cold-flow improver additives currently on the market as well. 4.24: Section 80.592 specifies the data which must be kept and maintained for all diesel batches but does not require submission to EPA unless requested. Section 80.604 requires annual submission of each batch of NRLM diesel or heating oil. However, the June 29, 2004 Preamble, section V(G)(5)(b) requires batch reports to be submitted, but does not specify between Highway or NRLM diesel. Please confirm that there are not any additional quarterly or annual reporting requirements for individual batch data of Highway diesel (15 or 500 ppm). In addition, does EPA plan on requesting this data? A: There are no additional requirements, nor does EPA plan to request additional data; the only requirements are volume and designation information plus identification information. 4.25: If a refinery receives a previously designated distillate (PDD), what options does the refinery have for blending the PDD and how are any changes in fuel designation handled? In other words, is there a provision similar to the gasoline rule where a previously designated material may be debited from a compliance pool using a negative volume? Does a similar provision exist in the distillate rule? Alternatively, is the refinery to handle PDD as a terminal and be subject to the same downgrade rules as the terminal? A: There is no similar provision to the RFG/anti-dumping regulations that would treat previously designated distillate fuel as a negative batch when it is blended with blendstock at a terminal blending facility or other refinery. A facility that receives previously designated distillate must be registered as a downstream facility and make appropriate records and reports regarding designation and tracking of the previously designated distillate, including any downgrading or other change in designation of that fuel volume. In addition, if the refiner blends blendstock to the previously designated distillate, it must, in its capacity as a refiner, properly designate that additional volume and is responsible for all refiner requirements for that added volume. For example, if 100 gallons of high sulfur blendstock is added to 100 gallons of 15 ppm highway fuel, and the resulting 200 gallons ofproduct is sold as 500 ppm highway fuel, in its capacity as a downstream facility, the facility would have to account for the downgrade of the 100 gallons of 15 ppm fuel to 500 ppm highway fuel. In its capacity as a refiner, it would be responsible for producing 100 gallons of500 ppm fuel. If the example above is changed such that the product blended is 100 gallons of previously designated high sulfur fuel to 100 gallons of 15 ppm highway fuel, then there is no refining activity; there is just a change in designation and downstream downgrade of the 15 ppm fuel that is used for the blending to 500 ppm highway fuel. 40 ------- 4.26: Do the Credit Trading Area (CTA) regulations as defined in section 80.531 apply only to importers? A: No, CTAs apply to both importers and refiners. 4.27: Section 80.532(d) implies that credits cannot be traded from one CTA to another- does this restriction apply only to imported fuel or can credits generated by a refinery located in PADD 1 (CTA 1) trade credits with a refinery in PADD 2 (CTA 2)? A: This applies to both refiners and importers, and highway credits can only be traded within a CTA. 4.28: In earlier Q&As for gasoline, EPA designated that the Virgin Islands and Puerto Rico are in PADD 6; Guam, American Samoa and the Northern Mariana Islands are in PADD 7. Since CTAs are nearly identical to the corresponding PADDs why has EPA chosen CTAs 6 and 7 for Alaska and Hawaii, and will EPA reconsider these designations? A: EPA does not intend to modify the credit trading area designations, we believe the current designations are clear and understandable. 4.29: What value are the non-highway baselines that are discussed in § 80.533 since they are not used in any credit generation equations or other compliances? A: § 80.533 explains that non-highway baselines are generated and used by small refiners to comply with any of the options available to small refiners under 80.554; and other refiners for the purposes of early credit generation. 4.30: The preamble states (page 39061), "[the] rule allows terminal operators and others to switch the designation of500 ppm sulfur NRLM diesel fuel to highway diesel fuel on a temporary but not a cumulative basis over time." a) What "others" is EPA referring to? b) What is temporary? c) What if a party has not switched 500 ppm highway diesel back into the 500 ppm NRLM market by 2012 when there is no longer a market for 500 ppm NRLM (when NRLM must be at 15 ppm)? A: a) The word "others " in the sentence refers to pipeline operators. b) "Temporary" is within the compliance period. c) The party will be subject to quarterly compliance until 2010, and annual compliance thereafter. Any noncompliance will be detected at the end of each compliance period. 4.31: Considering the likely contamination of large amounts of ULSD and the permissive downgrading provisions, will ULSD continue to be the dominant fuel at the pump in 41 ------- 2006? A: Yes. Anti-downgrading allowances for eachfacility are 20%. However most facilities will try to limit downgrading. For even the likely worst case facility, downgrade through normal contamination is expected to be less than 10%, and typically only a few percent or less. In total, downgrade due to contamination is expected to average less than 5%. Consequently, it should not significantly impact the availability of 15 ppm fuel. 4.32: How will the end-user know whether they are refueling with fuel in excess of 15 ppm sulfur? A: The regulations require that all fuel pumps be labeled to inform the user which fuel they are dispensing into their vehicle. These labels will state which engines/vehicles that the specific fuel is suitable for use in. These labels will match comparable labels on 2007 and later highway vehicles. Distributors will likely have testedfuel batches at retail to ensure that the fuel meets the applicable standard that is on its pump label. 4.33: If a retailer or wholesale purchaser-consumer does not dispense early credit 15 ppm sulfur cap motor vehicle diesel fuel, is June 1, 2006 the effective date for the pump labeling standards at § 80.570 per § 80.500(e)? A: Pumps which dispense on-roaddiesel containing 15ppm sulfur or less are required to be labeled as such starting June 1, 2006. 4.34: Under 40 CFR § 80.592(b) what is meant by a batch of diesel fuel and designating a batch number? 15 ppm sulfur content highway fuel will typically be produced continuously as the output from a distillate hydrotreater and is not blended like gasoline. The concept of batch numbering and batch volumes does not seem to make sense based on the production of this product. Please provide clarification. A: Under 40 CFR § 80.2(nn), a batch of motor vehicle diesel fuel "means a quantity of diesel fuel which is homogeneous with regard to those properties which are specifiedfor motor vehicle diesel fuel under subpart I of this part. " A batch of motor vehicle diesel fuel is thus a discreet and identifiable quantity of such homogenous diesel fuel. Thus, under the regulations, the volume and properties of even continuous streams are only measured periodically and it would be best to apply the measurements to the volume produced most closely to the time of the measurement. In other words, a refiner should break up a continuous stream into discrete batches to assure that the batch is a homogeneous mixture, andfor purposes of record keeping and reporting under §§ 80.592 and 80.593. It is our understanding that diesel fuel is not generally produced by in-line blending processes but is blended into a tank, where the volume and properties can be 42 ------- measured. As with the RFG/anti-dumping rule, the refiner would have to be consistent when calculating the volumes and properties of batches, consistently basing them on either shipped volumes or produced volumes. Otherwise double counting of volumes and properties could occur. Assignment of batch numbers will be done the same way under the highway diesel sulfur rule as is done under the RFG and anti-dumping regulations. See §§ 80.592(b)(2) and 80.65(d)(3). 4.35: Diesel fuel retailers will not be making 15 ppm motor vehicle diesel fuel; we will only be selling it to customers for use in their diesel-powered vehicles. What are a diesel retailer's primary regulatory responsibilities under the 15 ppm highway diesel fuel program? A: Responsibilities are similar to those under other fuels rules. While the responsibility for producing or importing compliant 15 ppm sulfur content highway diesel fuel resides with refiners and importers, retailers and all other parties in the distribution system share responsibility for assuring that diesel fuel subject to the 15 ppm standard is not contaminated or commingled with other products, such as distillates having a sulfur content greater than 15 ppm. At the retail dispenser, if the fuel subject to the 15 ppm sulfur standard does not meet the standard, it is in violation, subject to a 2 ppm test result adjustment applied to test results at downstream facilities. All parties in the distribution system are presumed liable for such violations, including the retailer (§ 80.612). Each party may establish a defense to the violation under § 80.613. A retailer may establish a defense by showing it did not cause the violation and that product transfer documents account for the fuel in violation and indicate the violating product was in compliance when it was under the retailer's control. In addition, retailers and wholesale purchaser-consumers are required under the regulations to post labels on each diesel fuel pump stand, notifying customers of the type of fuel dispensed by each dispenser. The required language for these labels is prescribed by § 80.570. Per §80.610, retailers are prohibitedfrom introducing, or permitting, the introduction of noncomplying fuel into motor vehicles. Model year 2007 and later diesel powered vehicles, which will require fuel meeting the 15 ppm sulfur standard, will have a label on the filler inlet and on the dashboard stating "Use Ultra Low-Sulfur Diesel Fuel Only " or "Ultra Low-Sulfur Diesel Fuel Only. " A retailer would clearly be liable for the action of a retail employee introducing 500 ppm diesel fuel into a vehicle equipped with such a label. Misfueling is addressed in more detail below. Retailers must retain all product transfer documents, which identify the 43 ------- applicable standard of the fuel, and must assure that this fuel is delivered into the proper storage tank for sale to customers (see §§ 80.590, 80.591 and 80.592). If a misdelivery does occur, retailers must immediately cease sales from the dispensers served by the impacted storage tank and assure that the product in the tank is brought back into compliance before resuming sales. Retailers should train their employees, and work closely with distributors and carriers who supply product to their outlets, so that the tank truck drivers will have needed information about what types of product are sold at each outlet and which storage tank corresponds to each type of product. The truck distributors themselves should in turn work closely with the retail operations, and ensure drivers know which product should be delivered to each station, and what storage tank each type of product should be delivered to. Truckers should ensure that high sulfur products previously carried in truck compartments have been completely drainedfrom the truck compartments and hoses before 15 ppm product is loaded into those compartments. Retailers are also subject to downgrading limitations of the regulations (§ 80.527). This is addressed in more detail elsewhere. Retailers who downgrade 15 ppm highway fuel to 500 ppm highway fuel must keep records that demonstrate compliance with the limitations and requirements of the downgrading provisions (see § 80.527(g)). 44 ------- 5. Cetane Index/Aromatics Requirements 5.1: In 80.510(h), does EPA really mean that the cetane index (CI) doesn't have to be met if sulfur is met with credits? A: The cetane or aromatics requirement only applies to NRLMfuel that is required to meet either the 15 ppm or 500 ppm std. If fuel is produced to uncontrolled sulfur levels through, for example, credits or hardship provisions, that fuel does not have to be controlled to meet EPA's cetane or aromatics standards either. However, industry standards will still apply. 5.2: How can heating oil be used as NRLM when heating oil does not necessarily meet cetane and aromatics requirements? A: The rule allows distillate designated as heating oil to be redesignated as high sulfur NRLM provided that during any compliance period there was no net shift of heating oil into the NRLM market (per § 80.598(b)(9)(viii). Please refer to the volume balance requirements for high sulfur NRLM and heating oil contained in 40 CFR 80.599(c). To meet these volume balance requirements, for any volume of heating oil redesignated as high sulfur NRLM during a compliance period, an equal volume of high sulfur NRLM would typically need to be redesignated as heating oil during that same compliance period. Any volume of heating oil redesignated as high sulfur NRLM would be required to meet the applicable cetane and aromatics requirements. 45 ------- 6. Sulfur Standards 6.1: In § 80.510(h), should it be "or" rather than "and". As currently written, only get exemption if credits, SR, hardship, and temporary relief? A: Yes, it should say "or EPA intends to correct this as part of a subsequent technical amendment rulemaking. 6.2: Have refiners based their production forecasts on 15 ppm ULSD, or some much lower pipeline spec? A: Our understanding is that production is set based on a range offactors and as such, different refineries have different targets. 6.3: If 15 ppm kerosene may be blended with 15 ppm ULSD, does the kerosene also have to be certified as #1 ULSD? A: No, although 15 ppm kerosene not previously certified as #1 ULSD will count against the party, provided that its highway volumes do not increase. Consequently, we expect that most #1 15 ppm will be designated as motor vehicle diesel fuel. 6.4: Should 15 ppm max sulfur No. 1 diesel or dual certified Jet/No. 1 diesel that is designated as 15 ppm diesel fuel when leaving the refinery be counted as 15 ppm diesel fuel in determining compliance with the 80% 15 ppm diesel fuel refinery production requirement for the Temporary Compliance Option? A: Yes, if a refinery designates either No. 1 diesel or dual certified Jet/No. 1 diesel under as motor vehicle diesel fuel meeting the 15 ppm sulfur standard under § 80.520(a)(1), it is counted as 15 ppm diesel fuel in determining compliance with the Temporary Compliance Option. 6.5: Subsequent sale of the 15 ppm max sulfur dual certified kerosene as commercial jet fuel is permitted, is not subject to any downgrading limitation, and does not impact compliance with the 80% 15 ppm diesel fuel production requirement for the Temporary Compliance Option? A: Correct, if a refinery designates kerosene as motor vehicle diesel fuel, then sells the kerosene as commercial jet fuel, then the reclassified volume of kerosene is not subject to any downgrading limitation, and does not impact compliance with the 80% 15 ppm diesel fuel production requirement for the Temporary Compliance Option. 46 ------- 6.6: Many refiners currently make a jet fuel meeting <500 ppm requirements. If refiners make a jet fuel meeting 15 ppm requirements, there may be compatibility (safety or performance) issues for jet engine manufacturers. Have these manufacturers been consulted in this rulemaking process? If so, what is their position on use of 15 ppm jet fuel? A: The highway and nonroad diesel programs do not require that refiners produce 15 ppm sulfur jet fuel and do not set sulfur limits for jet fuel that is not designated as motor vehicle diesel fuel. This would be their decision. EPA believes compatibility issues raised by 15 ppm jet fuel would be addressed by the refiners and customers involved. 47 ------- 7. Additives 7.1: Will there be an allowance for other additives - like cetane enhancer? A: New provisions were adopted in the nonroadfinal rule for anti-static additives downstream at the terminal. These provisions were adopted because all known anti-static additives were found to contain elevated levels of sulfur, and they needed to be added downstream at the terminal. The provision allows the addition of additives that exceed 15 ppm sulfur, but only if certain conditions are met, as specified in § 80.521. We are not aware of any similar situation with any other types of additives that would warrant similar consideration. 7.2. Subsequent use of No.l Diesel or dual certified kerosene for winter blending in 15 ppm diesel fuel is not an issue, but is winter blending into 500 ppm motor vehicle diesel fuel subject to the 20% downgrading limitation by each custody or title holder on an annual basis? A: Per § 80.527, the anti-downgrading limitations, as modified in the nonroad rule, only apply to #2 15 ppm diesel fuel. 7.3: Some refiners, and some distributors, blend additives into diesel fuel to improve performance. Is EPA taking any steps to assure that these diesel fuel additives do not contain sulfur at levels in excess of 15 ppm? A: The highway diesel fuel rule requires diesel additive manufacturers to label their additives, both on the container (in the case of additives sold to consumers- see § 80.591(d)(1) and (2)), and on the PTD (see § 80.591(b)(2)), with information as to the sulfur level in the additive. If the additive contains more than 15 ppm sulfur, then it is the blenders' responsibility to assure that the use of the additive does not result in diesel that exceeds the 15ppm standard (see § 80.521). Additives soldfor consumer use in model year 2007 and later vehicles may not contain more than 15ppm sulfur (see § 80.591(d)(2)). 7.4: It is a common practice for diesel fuel to be blended with kerosene to improve performance characteristics (particularly during cold weather), or other substances, such as used oil to dispose of waste products. Can such practices be continued under the 15 ppm diesel fuel program? A: Under § 80.522, used motor oil, or used motor oil blended into diesel fuel, may only be used in the fuel system of model 2007 or later diesel motor vehicles if the vehicle or engine manufacturer has received a Certificate of Conformity under 40 CFR Part 86, that certification is explicitly based on emissions data, and the motor oil is added at a rate consistent with the Certificate of Conformity. Under § 48 ------- 80.525, kerosene that a kerosene blender adds (or intends to add) to 15 ppm sulfur diesel must meet the 15 ppm sulfur content standard, as indicated by product transfer documents or test results. 7.5: Kerosene is used for residential heaters, city bus fleets, and jet fuel among other uses. It is also used to winterize diesel fuel and home heating fuel. Today, kerosene comes in two grades, < 500 ppm sulfur and < .3% (3000 ppm) sulfur. It may or may not be dual purpose, i.e. suitable for jet fuel use. To minimize grades, refiners will likely produce only one grade of winterizing fuel, 15 ppm nominal maximum. Will 15 ppm kerosene that is used to winterize 500 ppm diesel fuel be considered a downgrade and count toward the 20%? A: No, 15 ppm kerosene usedfor wintertime blending will not be considered downgrading. 49 ------- 8. Credits 8.1: §80.599(b)(6) states "Calculations in paragraphs (b)(4) and (b)(5) of this section may be combinedfor all facilities wholly owned by an entityMay this combination include facilities in different Credit Trading Areas? [80.599(b)(6)] A: Yes. The Credit Trading Area restriction on highway diesel fuel credit generation and use only applies to refinery production and not to subsequent movement of the fuel through the distribution system or downstream compliance under the designate and track provisions. 8.2: In § 80.535, the regulatory language covers generation of high sulfur credits for early production of 500 ppm NRLM and generation of 500 ppm credits for early (2009) production of 15 ppm NRLM. Can a refiner with some facilities that will be producing 15 ppm NRLM starting in 2006 generate high sulfur credits for early production of 15 ppm NRLM in 2006, as long as it does not double count these credits? A: No- in order to receive NRLM credit, the fuel must be designated as NRLM. Further, to receive high sulfur credits, the fuel must at least meet the 500 ppm sulfur standard. Per §80.598 (a)(3)(iv), any fuel designated as 15 ppm until June 2009 must be designated as motor vehicle diesel fuel in order to maintain the intended benefits and integrity of the highway program. Such fuel can always be usedfor NRLM purposes. However, in order to receive NRLM credit in the situation described in the question, the fuel would have to be designated as 500 ppm NRLM by the refiner even though it met the 15 ppm standard. 8.3: For each of the four compliance periods between 6/1/2006 and 12/31/2009, an interpretation of § 80.530(a)(3)(i)(A) is the following: V50o < [0.2 x (V15 + V500)] + credits from the same Credit Trading Area, where the units are gallons. Is this algebraic interpretation correct? A: Yes. For each compliance period between 6/1/2006 and 12/31/2009, inclusive, the volume of diesel produced or imported at 500 ppm is limited to the sum of any credits properly generated and used by the refiner or importer, or properly transferred to and used by the refiner or importer from within the same Credit Trading Area, plus 20 percent of the total volume of VI5 and V500 diesel produced or imported. There are also certain additional requirements on the generation and use of credits. See §§ 80.531 and 80.532. 8.4: For the compliance period from 1/1/2010 through 5/31/2010, an interpretation of § 80.530(a)(3)(i)(B) is the following: 50 ------- V5oo < credits from the same Credit Trading Area, where the units are gallons Is this interpretation correct? A: Yes. For the period 1/1/2010 through 5/31/2010, the volume ofdieselproduced or imported at 500 ppm is limited to the sum of any credits properly generated and used by the refiner or importer or properly transferred to and used by the refiner or importer, from within the same Credit Trading Area. There are also certain additional requirements on the generation and use of credits. See §§ 80.531 and 80.532. 8.5: Carryover of a small deficit is permitted, if two conditions are met in the immediately following compliance period. There is a limit on the size of this deficit. § 80.530(a)(6): "... However, for any compliance period prior to and including 2009, a refiner and importer may exceed the volume limit in paragraph (a)(3) of this section by no more than 5 percent of the volume of Vt of diesel fuel produced or imported during the compliance period, . . ." An interpretation of this 5 percent limit is the following: V500 > [0-2 x (V15 + V500)] + credits, if two conditions are met in the immediately following compliance period and if V500 - ([0.2 x (V15 + V500)] + credits) < 0.05 x (V15 + V500), where the units are gallons and the credits must be generated in the same Credit Trading Area that they are used. Is this algebraic interpretation correct? A: This algebraic formula correctly calculates the volume of deficit that can be carried over under § 80.530(a)(6). The volume of500 ppm diesel produced or imported in any compliance period may exceed the volume limit of500 ppm diesel allowed in that compliance period provided that 1) the volume of500 ppm diesel does not exceed 5 percent of the total volume of VI5 and V500 diesel produced or imported during the compliance period, and 2) in the succeeding compliance period, the refiner or importer meets the volume limit for that year on V500, and produces or imports 15 ppm diesel, or uses credits, equal to the volume of the exceedance in the preceding compliance period. 8.6: The definition of V500 is included in § 80.531(a)(2): "V50o = the total volume in gallons of diesel fuel produced or imported that is designated under § 80.598(a) as motor vehicle diesel fuel and subject to the 500 ppm sulfur standard under § 80.520(c) plus the total volume of any other diesel fuel (not including VI5. diesel fuel that is dved in accordance with § 80.520('b) at the refinery or import facility where the diesel fuel is produced or imported, or diesel fuel that is designated as NRLM under § 80.598(aV) represented as having a sulfur content less than or equal to 500 ppm." (emphasis added) Please explain the underlined text above. What is this "other diesel fuel"? A: "Other diesel fuel" means any distillate products that meet the definition of diesel fuel, such as kerosene, that is represented to have a sulfur content less than or equal to 500 ppm. Any volume of refined distillate products containing less than 51 ------- 500 ppm sulfur that is not designated as motor vehicle diesel fuel, should not be included in the total volume of motor vehicle diesel fuel. 8.7: The federal temporary compliance option (TCO) includes a credit trading program with a relevant restriction: if a refinery produces diesel fuel for a state 15 ppm sulfur cap program for a greater volume than the federal requirement, then that fuel is excluded from the federal credit program. See § 80.53 l(a)(5)(iv). This restriction applies to both motor vehicle diesel fuel produced in that state or imported directly into that state. 8.7a: The Texas Low Emissions Diesel (TX LED) rule (with its 15 ppm sulfur cap for highway and non-road diesel in three ozone nonattainment areas and 95 eastern/central counties beginning on June 1, 2006) possibly excludes a significant volume of ULSD from the federal TCO credit generation program beginning on June 1, 2006. On October 15, 2001, EPA Region 6 approved the TX LED program as necessary for Houston-Galveston ozone attainment; this approval was published in the Federal Register on November 14, 2001 (66 FR 57196). If it meets the requirements in § 80.531, will 15 ppm TX LED be included in the federal TCO credit program beginning on June 1, 2006 because, although the 15 ppm TX LED rule includes non-road diesel fuel and excludes the federal temporary compliance option, the 15 ppm TX LED volume is not expected to be greater than the federal 15 ppm diesel fuel requirement in the state? Will early 15 ppm sulfur cap TX LED produced before June 1, 2006 qualify as an early federal TCO credit if it meets the requirements in § 80.531? Or will § 80.53 l(a)(5)(iv) exclude all motor vehicle diesel (TX LED and other diesel) produced in or imported into Texas beginning on June 1, 2006 from the federal TCO credit program because "no motor vehicle diesel fuel produced in that state or imported directly into that state may generate credits under this subpart, . . ." even though this Texas diesel sulfur regulation will only apply to part of the state? A: The highway diesel program limits the ability to generate credits for fuel produced or imported directly into a State with its own diesel fuel requirement that requires a greater volume of 15 ppm or lower fuel than the Federal program. Upon evaluating the Texas LED program in the context of § 80.53l(a)(5)(iv), we have concluded that, while the Texas program is more stringent for a portion of Texas, it does not appear to require a greater volume of fuel on a statewide basis to be 15 ppm than will be required under the Federal program. As a result, in this specific instance, the limit on credit generation in § 80.53l(a)(5)(iv) does not apply to the Texas program. 8.7b: On February 24, 2000, CARB approved the Public Transit Bus Fleet Rule and Emissions Standards for New Urban Buses. This includes a diesel fuel sulfur cap of 15 ppm for transit agencies effective July 1, 2002. Does this CARB 15 ppm 52 ------- diesel fuel for public transit bus fleets qualify for the federal TCO credit program, if the conditions in § 80.531 are met, because California is not subject to the waiver of federal preemption provisions in the Clean Air Act? Or does § 80.53 l(a)(5)(iv) exclude all motor vehicle diesel fuel produced in California from the federal TCO credit program because "no motor vehicle diesel fuel produced in that state or imported directly into that state may generate credits under this subpart, . . ." even though this CARB diesel sulfur regulation only applies to public transit bus fleets? A: The § 80.53l(a)(5)(iv) restriction does not apply to fuel produced prior to June 1, 2006. Credit for fuel produced prior to then is subject to the provisions in § 80.531(b) and (c). Given that this program covers less than half of the diesel fuel sold in California, it would also not be considered to require a greater volume of 15 ppm diesel fuel than the Federal program under the provisions of § 80.531(a) (5)(iv). 8.7c: On September 15, 2000, the South Coast Air Quality Management District (SCAQMD) adopted a diesel sulfur content cap of 15 ppm effective on October 1, 2005. Will this SCAQMD 15 ppm diesel fuel qualify for the federal TCO credit program, if the conditions in § 80.531 are met, because California is not subject to the waiver of federal preemption provisions in the Clean Air Act? Or will § 80.53 l(a)(5)(iv) exclude all motor vehicle diesel fuel produced in California beginning on October 1, 2005 from the federal TCO credit program because "no motor vehicle diesel fuel produced in that state or imported directly into that state may generate credits under this subpart, . . " even though this SCAQMD diesel sulfur regulation will only apply to part of the state? A: Please refer to responses a and b, above. The SCAQMD issue is similar to the Texas LED issue. Given that this program covers less than half of the diesel fuel sold in California, it would also not be considered to require a greater volume of 15 ppm diesel fuel than the Federal program under the provisions of § 80.53l(a)(5)(iv). However, since CARB has subsequently adopted a similar state-wide program for 15 ppm diesel fuel (for highway and off-highway use), it requires a greater volume of 15ppm diesel fuel than the Federal program and the restrictions in § 80.531(a)(5)(iv) apply. Credits must be designated by refinery or importer-port of import, year of generation, and Credit Trading Area (1-7) of generation. In 2005 and 2006, is it necessary to further designate credits generated before June 1 versus after May 31 because § 80.531(c) has an early credit period from June 1, 2005 through May 31, 2006? A: For reporting purposes, it is not necessary to distinguish between credits generated before June 1, 2006 (early credits) versus credits generated after June 53 ------- 1, 2006. Specifically, § 80.593 states that annual compliance reports must contain information regarding credits for each refinery or, in the case of importers, by Credit Trading Area. For record keeping purposes, refiners and importers must keep information on credits separately for each calendar year compliance period and separately for each refinery (or in the case of importers, for each Credit Trading Area). However, § 80.592(b) also specifies that refiners and importers must keep documentation on the calculations used to determine the number of credits generated. Since there are three ways to generate credits under the program, credit calculations must be appropriate for the given time period in which the credits are generated.1 8.9: For reporting the percentage of motor vehicle diesel fuel produced meeting the 15 ppm sulfur standard after the inclusion of any credits, an interpretation of § 80.593(a)(4) is the following: % = 100x[(V15 + credits)/(V15 + V50o)] where the credits must be generated in the same Credit Trading Area that they are used. Is this algebraic interpretation correct? A: Yes, this algebraic formula correctly calculates the percentage offuel that must be reported under § 80.593(a)(4), where V15 and V500 have the meanings provided in § 80.531(a)(2), and "credits" means credits that are properly generated and used under the regulations. 8.10: Adequate volume of 15 ppm highway diesel fuel produced today for the testing of the distribution system is key to resolving uncertainty in a timely manner and working out implementation issues. What is EPA doing to encourage refiners to produce test batches of 15 ppm highway diesel fuel so that downstream parties can test models and assumptions while there is still time to modify systems prior to 2006? Is it possible to credit current production? A: To ensure a smooth transition to large-scale production and distribution of 15 ppm highway diesel fuel beginning June 1, 2006, the program allows for refiners to generate early credits. From June 1, 2001 through May 31, 2005 refineries and importers may generate credits based on the volume of 15 ppm sulfur highway diesel fuel that is used in vehicles with engines that are certified to meet 1. From June 1, 2001 through May 31, 2005 refineries and importers may generate credits based on the volume of 15 ppm sulfur highway diesel fuel that is used in vehicles with engines that are certified to meet the model year 2007 heavy-duty engine PM standard under 40 CFR 86.007-11. 2. From June 1, 2005 through May 31, 2006 refineries and importers may generate credits based on the volume of 15 ppm sulfur highway diesel fuel that is dispensed at retail outlets or wholesale purchaser-consumer facilities. 3. From June 1, 2006 through December 31, 2009 refineries and importers may generate credits based on the volume of 15 ppm sulfur highway diesel fuel produced above the 80 percent threshold. 54 ------- the model year 2007 heavy-duty engine PM standard under 40 CFR 86.007-11. From June 1, 2005 through May 31, 2006 refineries and importers may generate credits based on the volume of 15 ppm sulfur dieselfuel that is dispensed at retail outlets or wholesale purchaser-consumer facilities (i.e., the volume of 15 ppm fuel that is kept segregated and uncontaminated all the way through the distribution system and to the end user). Under the existing regulations, diesel fuel used to test the distribution system does not generate early credits unless it meets the above criteria. However, based on recent discussions with interested stakeholders, the Agency is also investigating whether it would be appropriate to allow early credits for test batches of 15 ppm sulfur diesel fuel which, while starting out as 15 ppm may end up at a higher sulfur level prior to sale to the end user. The Agency is in the process of developing a proposal to allow this. 8.11: Can credits generated by meeting the 15 ppm highway diesel sulfur standard early be used in the gasoline program? A: No. However, the regulations at § 80.540 allow a GPA refiner to extend its sulfur standards for gasoline from December 31, 2006 to December 31, 2008 if the GPA refiner produces 95% of its on-road diesel as 15 ppm diesel (at a volume that is at least 85% of its baseline volume) by June 1, 2006. Also, the regulations at § 80.553 allow a small refiner to extend its sulfur standards for gasoline to December 31, 2010 if the small refiner produces 95% of its on-road diesel as 15 ppm diesel by June 1, 2006 (at a volume that is at least 85% of its baseline volume). 55 ------- 9. Product Transfer Documents (PTDsVBills of Lading (BOLs) 9.1: Please verify that the "product document requirements" of §80.590 do not apply to transfers where an entity maintains custody of a batch of diesel fuel from one place in the distribution system to another place (e.g., from a refinery to a pipeline or a pipeline to a terminal), all owned by the same entity. It is understood that records must be retained under §80.600(a)(7). A: Product transfer documents must be exchanged when a product changes custody. A facility is defined as a location or series of location where custody does not change, therefore product transfer documents do not need to be exchanged between locations within a single facility. 9.2: Must BOL's contain the exact words of this section? (§§ 80.590, 80.598) A: For parties upstream of the retail outlet or wholesale purchaser-consumer, the PTDs required under the regulation may use product codes, except that the sulfur content standard must appear in numeric form (15, 500 or >500). For PTDs to retail outlets or wholesale purchaser-consumers, the exact language must be used. 9.3: Can codes be used to designate facility IDs on PTDs, or does the entire facility ID need to be on the PTD? A: To ensure accurate handoff accounting under D&T, PTDs require the disclosure of the full 9 character Facility ID (EPA assigned 4 character Company ID plus EPA assigned 5 character Facility/Activity ID). 9.4: Are separate PTD documents required for diesel or will general procedures currently in place to meet gasoline PTD requirements be sufficient to meet PTD requirements for all grades of diesel? A: While there is substantial overlap in PTD requirements for gasoline and diesel, the requirements are not identical. 9.5: What data points will EPA want/need to allow pipelines to develop necessary PTD language? A: The information required on commercial PTDs includes identification of the transferee and transferor (including names and addresses of the parties, and registration number of transferor), the volume of product, the date and location of the transfer, and identification of diesel fuel distributed by use designation (for use in motor vehicles, NR equipment, LM equipment, or NRLM equipment) and 56 ------- the sulfur standard to which the fuel is subject. PTDs must indicate the type of fuel- whether diesel fuel, heating oil, kerosene, exempt fuel, or other. PTDs must also state if fuel is No. 1 or No. 2; dyed or undyed fuel; and marked heating oil, marked LM, or unmarkedfuel. Where a party delivers or receives fuel that has two different designations (but a uniform sulfur content), parties must use separate PTDs for each usage designation. At the point where fuel is taxed or dyed/marked, andfor subsequent transfers, the PTD must indicate the applicable fuel uses as well as the standard. This is not an exhaustive list of the requirements, a complete and detailed description of the specific requirements is located in § 80.590. 9.6: On the designate and track approach, is any specific information required to be written on the Bill of Lading (BOL) at the truckload rack? A: Section 80.590(d) provides that product codes may be used if such codes are clearly understood by each transferee (so long as the sulfur content standard, stated numerically in parts per million, is included), except that the information required by § 80.590 to be conveyed to truck carriers, retailers, wholesale pur chaser-consumers and mobile refuelers must be stated verbatim. See also § 80.590(g). 9.7: If a retailer or wholesale purchaser-consumer does not dispense early credit 15 ppm sulfur cap motor vehicle diesel fuel, is June 1, 2006 the effective date for the product transfer document (PTD) requirements at § 80.590 per § 80.500(e) or § 80.592(a)(1) or § 80.530(a)(2)? A: The PTD requirements apply to all motor vehicle diesel fuel under the highway diesel rule (both 15 ppm and 500 ppm) as of June 1, 2006. Prior to June 1, 2006, the PTD requirements apply only to transfers involving early credit fuel. Under § 80.590(h) and (i), starting June 1, 2001, any highway diesel fuel transfers that are subject to the early credits provisions of § 80.531(b) or (c) are subject to the PTD requirements. The 5 year retention period under § 80.592(a) applies to all required PTDs under the rule, including PTDs required under the additive provisions (see § 80.591). 9.8: Some pipelines operate a fungible batch system and some operate a segregated batch system. A shipper on a segregated batch system receives the batch that it tendered at the origin point. The pipeline has the responsibility to maintain batch quality while the batch is in its custody. If the pipeline delivers to third party tankage, the terminal operator is responsible for segregating interface and delivering to tankage. It is unclear where the pipeline's responsibility begins and where it ends, which could drastically affect the pipeline's sampling and testing program. (How is responsibility divided under the current 500 ppm program?) 57 ------- A: Pipelines are carriers under the regulations and as such have responsibility to ensure the product meets the standards while the pipeline has custody or title, and to provide appropriate product transfer documents to any downstream parties to whom it transfers custody. The responsibility to account for downgrade is a function of the point at which custody of the fuel is deemed to take place. This point is a function of contracts between the different entities. Each entity is responsible for all downgrading that occurs when it has custody. 58 ------- 10. Documentation 10.1: §80.600(a)(10) says, "Any refiner or importer shall maintain copies of all product transfer documents required under §80.590. If all information required in paragraph (a)(6) of this section is on the product transfer document for a batch, then the provisions of this paragraph (a) (10) shall satisfy the requirements of paragraph (a)(6) of this section for that batchDoes that mean that if a refiner or importer has a PTD containing the information no other record is required? That seems unneeded. Does that paragraph mean something else? A: Section 80.600(a) (10) first requires that product transfer documents under § 80.590 be maintained by refiners and importers. It then states that if such product transfer documents contain all the information required under paragraph (a)(6) of § 80.600for each batch, then no other separate recordkeeping is requiredfor that batch in order to satisfy the requirements of paragraph (a)(6). 10.2: Must records be retained if only #2D 15 PPM is received? In general, are requirements of 80.600(b) applicable if the distributor only receives #2D 15 PPM? [80.600(b)(l)(ii) and 80.600(b)(2)] A: Yes, records must be retainedfor this fuel (unless the fuel is dyed, marked, and/or taxed or in the Northeast/Mid-Atlantic Area or Alaska). In this case, the D&T reports would confirm that the distributor did not handle any other fuel and did not violate any of the restrictions on redesignating fuel. The D&T reports from this distributor would also be used in evaluating compliance by the parties before and after this party in the distribution system. This distributor is only one step in a chain offuel hand-offs, and the D&T system is designed to use information from each party to a hand-off to ensure compliance by all of the parties in the chain of distribution. Further, parties should retain records for defense purposes. 10.3: a) Are diesel batch numbers kept separate from gasoline batch numbers? b) Must numbers be chronological and contiguous? c) Are zero volumes allowed? [80.602(b)(2)] A: a) Yes. §§ 80.592, 80.593, 80.602(b)(2) and80.604 require that the batch numbering conventions set forth in § 80.65(d)(3) be usedfor diesel fuel. The regulations require batch numbering for diesel fuel to be separate from batch numbering for purposes of the gasoline rules (RFG/anti- dumping, gasoline sulfur), using the same batch numbering conventions for diesel as are usedfor gasoline, b) Numbers must be chronological and contiguous- under § 80.65(d)(3), the 1st batch for the year is number 1, with . . each subsequent batch during the calendar year being assigned the next sequential number. " Each 59 ------- batch number also includes the EPA company andfacility registration number and the last 2 digits of the year in which the batch was produced, c) Yes, zero volumes are allowed. For example this would be appropriate where a batch is tested, then re-blended and retested before any of it is transferred. Back-up records should be kept so that an adequate explanation exists regarding why there was a zero volume. 10.4: A tank truck common carrier picks up a load of ULSD at a Shell terminal and delivers it to a Flying J truckstop. The carrier only provides a transportation service, does that carrier have any registration or reporting duties? A: No, the carrier does not have registration or reporting duties as long as taxes were assessed (in the case of highway fuel) or dye was added (in the case of NRLM) at the terminal. There are recordkeeping andPTD requirements, however. These requirements are listed in detail in §§ 80.590 and 80.592 of the regulations. 10.5: A trucking company stores ULSD at its terminal for use in its own truck fleet. Does it have any registration or reporting requirements? A: No, but there are recordkeeping requirements; and such an arrangement may be considered, by definition, a "Wholesale Purchaser-Consumer 10.6: Is it correct that below the rack, the primary recordkeeping mandate is production and retention of PTDs with no reporting obligations? A: Yes, if requisite dye/marker has been added and/or taxes were paid (see 10.4). 10.7: Do product codes have to contain the sulfur amount if a description accompanies the code? Will EPA provide examples of code structure? A: The rule is clear as to the appropriate use of codes. The product codes on product transfer documents for MVNRLMfuel must contain the numeric designation of15, 500 or >500 (see § 80.590(d)). EPA does not prescribe a format for product transfer documents; any required information not already on commercial documents is generally expected to be added to such documents. 10.8: What compliance and reporting requirements are there if a company throughputs highway diesel at a 3rd party's terminal? A: Under the D&T regulations, the custody holder is the responsible party, and must comply with all recordkeeping and reporting requirements. In this example, it would in most cases be the terminal owner. However, in order to ensure compliance for the terminal as a whole, they may need to place their own 60 ------- compliance requirement(s) on the lessee. 10.9: Must individual batch reports be submitted for highway diesel (15 or 500 ppm)? Is this requirement for NRLM diesel only? A: With respect to highway diesel, batch reports are requiredfor participants in early credit generation and/or refiners covered under a Temporary Compliance Option, per § 80.581. 10.10: Is registration for an EPA number at a terminal required, and is it in addition to present TCN #? A: Yes, registration is required. The TCN # is usedfor the IRS system; the EPA D&T system is not based on the IRS model, but rather on our existing gasoline reporting programs. Facility ID numbers are assigned by facility, however, an aggregated facility or a single facility that serves many roles would need to state those activities (such as: refinery, importer, breakout (passthrough) terminal and/or pipeline, and truck loading terminal) in its reporting documentation. 10.11: a) What is the difference in reporting requirements for additives containing greater than 15 ppm, as well as those containing less than 15 ppm, sulfur? b) Will batch recertification change based on additive sulfur content? A: a) There is no reporting requirement for additives, only MVNRLM. b) Redesignation of a batch due to downgrading is limited to 20% of volume by facility. Additives having a sulfur content greater than 15 ppm that are used in ULSD must meet the standards and identification requirements of 80.521(b). 10.12: What registration and reporting requirements exist for 3rd party terminals and other service providers that never actually own the product with regard to ULSD? A: Under the designate and track regulations, custody holders are the responsible party for registration, recordkeeping, and reporting. 10.13: Since all entities in the distribution system will be required to report data, this creates double reporting as both the transferor and transferee would be reporting the same volume. Are there any plans or safeguards to be in place to allow a reporting entity to check and/or verify volumes that other entities have assigned to their entity or facility? A: There are no plans/requirements being put in place by EPA. Businesses may handle such a program themselves, as they see fit, as part of a quality assurance program. 61 ------- 10.14: Has the EPA defined the reporting application or process for the designated volumes reports? Will alternate methods, such as EDI or spreadsheet be allowed for submissions? A: The forms for this are currently under development. Yes, alternate methods- spreadsheets or flat files- may be usedfor submissions. 10.15: Will paper (bubble) reports continue to be required for individual batch submissions or will alternate methods, such as EDI or spreadsheet be allowed for submissions? A: No, as stated above in question 10.14, paper/bubble reports will no longer be required. Submissions will be in spreadsheet/flat file format. 10.16: Will EPA want electronic copies of quality control testing charts? A: EPA will want the original records (including test records). The original charts can be provided electronically, or we will accept paper printouts of electronic copies (or other hard copies). 10.17: In the preamble, EPA states, "the reporting forms can be standardized and the review process automated in such a fashion as to minimize the Agency resource requirements" (page 39062). What is EPA's intent with regard to such standardization? According to EPA, commenters stated that the information needed for D & T is already kept as part of normal business practices (pages 39061, 39069). What is EPA's understanding of "normal business practices" and the way this information is already kept? How does this mesh with EPA's statement on standardization? What are EPA's expectations of D & T documentation? How will EPA address the different ways that facilities "already keep" the documentation? What is EPA's expectation with regard to PTDs? Is EPA looking to create or require a standard PTD? Will EPA request electronic copies of PTDs? A: We are proposing a flexible reporting system which historically has been well received by industry because of its ease of use. No special software will be required (reports should be submitted in spreadsheet or flat file format). 10.18: What kind of local record keeping (at the terminal) will be required versus a centralized record keeping process? A: Sections 80.592(e) and 80.602(e) require that the required records be made available "on request by EPA. " The location where the records must be kept is not specified by the regulations. EPA interprets this requirement to require that records should normally be made available the same day they are requested. If they are stored off-site, EPA may request photocopies or facsimile copies be supplied pending receipt of original records, or EPA may visit the off-site facility to obtain the records. If voluminous records are requested by EPA, they must be provided within a reasonable time, which will generally be specified in the 62 ------- information request. 10.19: Will the terminals or pipelines have to provide consignees to interconnecting pipelines any documentation, or can they forward documentation from the source, or is no documentation an option? A. When a party transfers custody of designatedfuels in the distribution system the transferor must provide a PTD to the new custodian. PTDs contain a variety of information, some of which will not be included in information generated by prior sources of the fuel. No documentation is not an option in cases where a PTD is required. 10.20: Where (specific certified and express mailing addresses at EPA) should refiners and importers send the 2003, 2004 and 2005 pre-compliance information required in § 80.594? A: Certified mailing address for pre-compliance reports is, Attn: Diesel Sulfur (6406J) 1200 Pennsylvania Avenue NW Washington, DC 20460 Express (overnight/commercial carrier) mailing address for pre-compliance reports is, Attn: Diesel Sulfur Pre-compliance Report do: Chris McKenna (202-343-9037) 1310 L St. NW Washington, DC 20005 Also, please send electronic copies of all documents, ifpossible, particularly the spreadsheet template that EPA developedfor reporting estimates of 15 ppm production, 500 ppm production and credit generation and usage. Electronic copies can be submitted on a disk or e-mailed to mckenna.chris@epa.gov. 10.21: Not all on-road diesel fuel must be 15 ppm starting in 2006. The phase-in, small refiner, and geographic provisions of the final rule seem to assure that at least some 500 ppm diesel fuel will be in the market post-2006. But, for retailers and wholesale purchaser consumers, whether 500 ppm will be available in substantial quantities in their marketing areas is an important factor in deciding whether to invest in additional tankage in order to be able to offer customers both 15 ppm and 500 ppm diesel fuel. How can retailers and wholesale purchaser consumers gain information on the amount of 500 ppm that will be produced in their PADD post-2006? 63 ------- A: Refiners and importers are required to annually update EPA on their progress toward producing 15 ppm sulfur diesel fuel through the pre-compliance reports. We will produce a summary and analysis document of the pre-compliance reports submitted each year (the Summary and Analysis of both the 2003 and 2004 pre- compliance reports can be found at: http://www.epa.gov/otaq/diesel.htm). The annual summary and analysis reports will provide information, summarized and aggregated on a PADD basis, describing the volumes of 15 ppm and 500 ppm highway diesel planned to be produced, and estimates of the number of credits that refineries expect to generate or use. Further information on the business plans for individual parties in individual markets would need to be pursued directly by retailers and wholesale purchaser consumers. 10.22: EPA released its status report on the on-road diesel sulfur rule earlier this year (2002). From a retailer's point of view, there wasn't much helpful information in this status report in terms of which refiners are going to make 500 ppm in 2006 and beyond and in what qualities. Will these reports by refiners to EPA provide estimates of 15 ppm diesel fuel production? Or of 500 ppm diesel fuel production? A: Refiners and importers are required to submit annual pre-compliance reports under the highway rule from 2003 through 2005, and under the nonroad rule as late as 2011. These reports must contain estimates of the volumes of 15 ppm sulfur fuel and 500 ppm sulfur fuel that will be produced at each refinery, and, for those refineries planning to participate in the trading program, a projection of how many credits will be generated or must be used by each refinery. These pre- compliance reports must also contain information outlining each refinery's timeline for compliance and provide information regarding engineering plans (e.g., design and construction), the status of obtaining any necessary permits, and capital commitments for making the necessary modifications to produce low sulfur highway diesel fuel. Much of this information will be claimed as confidential business information (CBI). As a result, we will be unable to release individual refiner plans unless they give permission to do so. However, we do report the information in an aggregated, non-confidential format. Refiner- specific information will have to be pursued through individual business relationships. 10.23: What is the purpose of requiring record keeping and reporting for early compliance. If EPA is seeking to encourage early compliance these requirements may be burdensome for certain marketers? A: Record keeping and reporting for early compliance is required to ensure that 15 ppm credits are valid, as per § 80.531. 64 ------- 11. Testing 11.1: Per § 80.604(d)(5), must aromatics be reported (and run) if compliance is based on cetane index? A: No. Under §§ 80.510 and 80.520, MVNRLMdieselfuel may comply with either the cetane index or the aromatics standard. 11.2: For testing purposes at a terminal level, must each tank that is filled be tested or is it sufficient to test just the incoming pipeline shipment? A: There are no testing requirements downstream of the refiner and importer to verify that the sulfur content fuels received by a distributor is consistent with that reported on the PTD. However, every party in the fuel distribution chain that has had custody of a fuel batch with a sulfur content found to be excess of the sulfur standard reported on the PTD could be held presumptively liable for the resulting violation if they lack sufficient affirmative defenses. The issue of whether testing the sulfur content of the incoming pipeline shipment rather than that of each storage tank into which the fuel is delivered to establish the sampling and testing element of a terminal owner's affirmative defenses will be evaluated by EPA on a case by case basis. In instances where the tanks being filled with 15 ppm diesel fuel have been dedicated to 15 ppm diesel use, it will be more likely that pipeline receipt testing would be sufficient and that a test on the tank after the introduction of the fuel would not be necessary. In cases where the tank is alternately used to store higher sulfur fuel as well as 15 ppm diesel fuel, a test on the tank after the introduction of the fuel may be needed. 11.3: Do terminals need to test every batch? A: Terminals are not required to test terminal tanks after every receipt of product. However, to establish a defense to presumptive liability to a violation, a terminal must establish each defense element. One such defense element is that the terminal had a quality assurance program, including a periodic sampling and testing program. Since terminals receive very large volumes ofproduct in each receipt, an appropriate quality assurance program might require sampling and testing after each receipt of 15 ppm product. Note that terminals would have to test every batch in order to establish a defense if it is adding greater than 15 ppm sulfur content additives (or conduct the VAR approach under § 80.614, if the additive is a static dissipater additive). 11.4: Should testing at a terminal be done at the rack after injection of any additives? A: There are no sulfur testing requirements downstream of the refiner/importer. 65 ------- However, to meet their affirmative defense to presumptive liability, parties that blend >15 ppm sulfur additives into dieselfuel subject to the 15 ppm sulfur standard must conduct a periodic sampling and sulfur testing program after the additive is added to the fuel (see 40 CFR 80.613(d). Alternative affirmative defense requirements exist for blenders of >15 ppm anti-static additives that are based on a volume accounting reconciliation system (see 40 CFR 80.614). 11.5: Will EPA be testing diesel for compliance at the retail/vehicle level? A: Yes, EPA will be testing diesel for compliance at the retail/vehicle level. 11.6: Please elaborate on fuel tests at retail- what frequency would be recommended? A: Retailers are not required to perform testing in order to have a defense to presumptive liability. However, to establish a defense to a violation distributors must, among other things, conduct a periodic sampling and testing program. For a truck distributor, the best place to take samples may often be the tanks of retail outlets it delivers to. Retailers should probably sample and test after tank transition from a higher sulfur product to 15 ppm product, to confirm that the fuel in the tank is meeting the 15 ppm standard. Otherwise, if a violation is detected for some time subsequent to a tank transition, it may be difficult for the retailer to demonstrate that it did not cause the violation. 11.7: When does the 2 ppm tolerance apply? A: The 2ppm downstream sulfur test tolerance (§ 80.580(d)) applies at all locations downstream of the refiner/importer. 11.8: If XYZ Refining has a branded retailer who independently owns his/her XYZ Gas Station. Does XYZ Refining have a duty to test ULSD at XYZ Gas Station? A: A branded refiner is not required to test gasoline at its branded retail outlets whether or not the retail businesses are owned by independent third persons. However, under § 80.612, branded refiners are liable for violations at branded retail outlets. Under § 80.613, for branded refiners to establish a defense to such violations, it must, among other things, show that it has a periodic sampling and testing program at the branded retail outlets. 11.9: At what point in the distribution/receipt of ULSD will terminals need to sample/test for sulfur? If terminals do not test for sulfur content at the rack will they be able to assert an affirmative defense in the event that contaminated fuel is discovered at the retail level? A: Under the diesel sulfur program, there is no one time or physical location that a distributor must utilize for sampling. The party must use its knowledge of the 66 ------- distribution system, and information regarding each receipt of product (e.g., whether the shipment may include fuel that is very close to an interface with higher sulfur product) to determine when and where to sample. However, as a general matter, we believe that a terminal should take samples during and/or after receipt of new product into the tank so that if there is a problem, it can be discovered and remedied before the product is distributed further downstream. If there is reason to believe that piping or a tank may contain high sulfur product then that may affect both sampling strategy and actions to prevent a potential violation. This is but one example of many possible situations. In regards to terminals not testing for sulfur content at the rack, if a terminal does not conduct a sampling and testing program, it will likely be difficult to be able to establish a defense to presumptive liability. 11.10: If tests are done upon receipt from the pipeline, how will PTDs reflect sulfur contamination added by the terminal through common piping, manifolds or at the rack? A: These tests would not address contamination by the terminal. Also, PTDs do not need to specify the precise sulfur content of the fuel, only that the fuel is compliant with the applicable sulfur standard. If minor contamination occurs, but the fuel still meets the applicable standard, it is not considered a violation, nor does EPA require it to be reported on a PTD. 11.11: With regard to test methods, would EPA consider the following two approaches to be equally sound in terms of a defense to presumptive liability? (1) qualify the test method chosen for downstream oversight purposes per the precision and accuracy criteria in the rule; or, (2) correlate the test method chosen for downstream oversight purposes to a test method qualified per the performance based test method criteria? The methods appear to be equivalent and acceptable approaches. A: No, for the testing offuel for compliance with the 15 ppm sulfur standard, we do not consider the two approaches to be equivalent. The second approach listed is not an option for approval of a test method under the diesel fuel regulations, and therefore testing with methods not approved under § 80.581 and § 80.585 would not be considered an adequate defense to presumptive liability. Test results from test methods that have not been approved under the regulations might be considered as evidence of compliance or noncompliance with the standard, but use of the unapproved method would not be considered as meeting the periodic sampling and testing requirement for defense purposes; nor would use of an unapproved method be considered to have fulfilled the requirement for refiners and importers to test every batch. Testing for 500 ppm fuel has a different situation. 11.12: Is there a process, or a need, to certify a tank of 15 ppm sulfur content highway fuel that is not located in a refinery? Is it a single sample or Top-Middle-Bottom samples? Must 67 ------- it be by lab analysis? A: Parties in the distribution chain downstream of the refiner or importer are not required to test motor vehicle diesel fuel. However, in order to establish a defense to any violation, downstream parties must conduct a quality assurance program, including sampling and testing. The fuel must meet the standard on a per-gallon basis. An appropriate field method may be used for downstream quality assurance testing. The regulations do not specify which testing method must be usedfor downstream quality assurance testing. The sampling methods prescribed by the rule in § 80.580 would be appropriate for purposes of quality assurance sampling under § 80.613(d)(1). 11.13: Terminal operators believe it is appropriate for them, even when acting as a "downstream facility," to ensure that the diesel fuel leaving the terminal gate complies with the 15 ppm sulfur standard. Terminal operators recommend that EPA determine compliance when the product leaves the facility, not when the product is still in tank before distribution. However, if such testing and determination is to be conducted on product in storage, the EPA should use an "average" of the sulfur content of the tank to determine compliance. A: Fuel represented to meet the 15ppm standard that is stored, transported, dispensed, sold, offeredfor sale, supplied or offeredfor supply at a terminal must meet the 15 ppm sulfur standard on a per-gallon basis (not on an average basis). Terminals are not required to perform sampling and testing except as a defense to liability, but we strongly concur that responsible terminal operators will conduct regular sampling and testing - and that the appropriate frequency will probably be after each receipt of product. 11.14: Will EPA have an oversight testing program for 15 ppm motor vehicle diesel fuel similar to the RFG gasoline survey program? A: The RFG survey program is a statistically valid sampling and testing program that is performed by an independent contractor who is paid for by participating refiners. Its purpose is to show whether the RFG in each control area meets standards on average. No such program exists under the highway or nonroad diesel regulations. However, as with other fuels programs, EPA plans to conduct its own sampling and testing at all levels of the distribution system to monitor compliance with the diesel fuel standards. 11.15: As EPA is aware, terminals often serve in two different capacities - (1) as an import facility; and (2) a downstream facility when product is received from a U.S. refiner or importer. As such, terminal operators believe that the 2 ppm testing tolerance would only apply to those operations of the terminal when it is acting as a "downstream facility." Would EPA please confirm this interpretation. 68 ------- A: The 2 ppm test result adjustment of § 80.580 (d) does not apply for fuel at a facility that is acting in the capacity of an import facility. However, fuel that is in a terminal tank downstream from the refinery or import facility is eligible for the 2 ppm test result adjustment. 69 ------- 12. Enforcement 12.1: What will happen if you refuel a 2007 truck with contaminated fuel? Are there any engine or aftertreatment issues? If a 2007 truck is misfueled, is there any legal liability for the end-user? A: If a MY 2007 or later truck is misfueled once, it will have significantly higher PM emissions during operation on that fuel, but there should not be any significant long-term emissions or engine durability concerns as long as the truck is then fueled with the proper fuel. A wholesale purchaser-consumer or end user faces presumptive liability if it misfuels vehicles or equipment with fuel not meeting applicable standards. However, a vehicle operator fueling at a retail outlet from an appropriately marked pump is not liable for the misfueling caused by the retailer or other party. A wholesale purchaser-consumer (fleet operator with its own fueling facility- see definition at 40 C.F.R. § 80.2) may be able to establish a defense if the fuel was contaminated by an upstream party and the wholesale pur chaser-consumer can otherwise establish its defense elements that it did not cause the violation and that product transfer documents account for the product and demonstrate the product was compliant. 12.2: EPA appears to focus enforcement on the custodian of the fuel, even though a compliance violation may well have occurred further upstream. Will EPA automatically require custodians to raise a defense and overcome a presumption of liability for simply possessing off-spec fuel? A: The facility where the violation is found and all parties in the distribution system upstream of that facility will be presumed liable. However, each party has the opportunity to establish a defense to the presumptive liability. For example, an upstream distributor who takes custody of a fuel would be presumed liable, and would need to demonstrate that it did not cause the violation- that product transfer documents account for the fuel and show that the fuel was apparently in compliance when it was in its custody and that it has an adequate periodic sampling and testing program (regardless of whether or not it tested that specific batch offuel). However, if the fuel custodian is a retailer or wholesale pur chaser-consumer, they would not be required to have a periodic sampling and testing program in order to establish a defense. 12.3: The regulation requires an entity to conduct an investigation into the cause of a quality control testing violation. What evidence will EPA require for purposes of establishing that an adequate investigation was conducted? A: EPA is not in a position to discuss what may constitute an adequate investigation in every conceivable scenario. An adequate investigation is whatever is required 70 ------- to correct the cause of the deviation and to assure that the method performance has been restored to statistical control. 12.4: The rule states that a party that is initially deemed liable for a violation of the rule will not be deemed liable if the party demonstrates: (1) the violation was not caused by the party; (2) product transfer documents show that the violating product was in compliance when it was under the party's control; (3) the party conducted a quality assurance sampling and testing program. The rule at section 80.613 does not specifically require the party to prove all three factors (there is no "and"). However, the preamble (page 39104) says a party must show 1, 2 "AND" 3. It should be enough to show that the party did not cause the violation (first prong). How will EPA apply this test? A: The preamble is correct- a party that is presumed liable must establish all three elements (except for retailers and wholesale purchaser-consumers, which are not required to have a periodic sampling and testing program). This is consistent with all of the fuels rules in Part 80. We interpret the introductory language in § 80.613 (a)(1) to require that all elements subsequently listed be established. For example, where a truck distributor drops 500 ppm sulfur content fuel into a retailer storage tank that supplies a 15 ppm pump stand, both parties will be presumed liable. However, the retailer may establish a defense- even if it subsequently sold the fuel as 15 ppm fuel- if it can demonstrate that it did not cause the violation and that the PTDs account for the fuel as being 15 ppm fuel, and thus show the fuel to be in violation. (In this example, if the party in question was not a retailer, it would also need to demonstrate- regardless of whether or not it tested that specific batch of fuel- that it has an adequate sampling and testing program in place). If the product transfer document stated that the fuel was 500 ppm fuel, then the retailer cannot establish a defense unless it immediately stopped sale and took actions (probably in association with the distributor) to remedy the violation. If the retailer sells the product as 15 ppm fuel even though the product transfer document shows 500 ppm fuel was dropped, then it cannot meet the second element of its defense. 12.5: Under the rule, sampling and testing is voluntary for downstream parties, however, to establish a defense to presumptive liability, they will engage in periodic testing. If a downstream party is not in the midst of periodic testing and is found in possession of an off-spec batch, then the party will not be able to meet all of the three elements required for establishing a defense (see question 12.4, above). It would appear that it might be impossible to rebut the presumption if a party is not in the midst of scheduled QC sampling and testing. Is this correct? A: If a party conducts no quality assurance/sampling and testing, it cannot establish a defense. However, a party can satisfy the periodic sampling and testing element of its defense by demonstrating that its periodic sampling is done at a frequency that is appropriate given all of the circumstances. It is not necessarily 71 ------- required that the product EPA finds to be in violation was actually sampled and tested. However, for parties such as terminals, an adequate sampling frequency may require sampling after each receipt of product. EPA will investigate whether other parties may be liable, but each party must be able to establish a defense. 12.6: The end user has no way of knowing whether they are refueling with diesel in excess of the 15 ppm sulfur regulatory limit. Is there a way to introduce some flexibility in the enforcement of the requirement that no fuel in excess of 15 ppm sulfur be introduced into a 2007 (or later model year) truck? A: Flexibility inherently exists in the fact that everyone involved in the production and distribution chain of each batch of fuel is presumptively liable, which will help to limit the occurrence of fuel that does not meet the 15 ppm standard (or other applicable designation). A person fueling a vehicle at a retail outlet self-serve pump will not be liable for misfueling if the person does not cause the violation. For example, if the misfueling occurs because the retail outlet has mislabeled the pump stand or because the retailer or its distributor have contaminated the fuel with high sulfur product, the retailer and parties upstream may be liable, but the self-serve customer will not be liable unless it played some part in causing the violation. However, if, for example, a person fuels a 2007 MY truck at a self serve pump labeled as dispensing 500 ppm fuel, the end user is liable. 12.7: Will testing documentation from a receiving pipeline be sufficient evidence of compliance with the sulfur standard to continue delivery? Will this document track through to a truck load without additional testing and be sufficient to establish a defense to liability for a violation of the sulfur standard? A: EPA will sample and test diesel fuel at all levels of the distribution system. If, for example, the sulfur test result for a particular sample downstream of the refinery exceeds the 15 ppm sulfur standard (after the adjustment under 40 C.F.R. § 80.580(d)), that fuel will be in violation regardless of any prior test result demonstrating compliance. Note that fuel from each refiner and each pipeline is frequently commingled in the fungible distribution system. Fuel may be contaminated in the pipeline or in storage tanks during shipment. Where a violation is found, the party having custody of the fuel that is found in violation, and any party upstream of the facility where the violation is found is presumptively liable. However, each party may establish a defense by meeting each of its defense elements. For example, a distributor may establish a defense to a violation found at a retail outlet if it can show that: it did not cause the violation; product transfer documents account for the fuel and indicate that the violating product was in compliance with applicable requirements when it was 72 ------- under the party's control; and the party conducted a periodic sampling and testing program and other quality assurance efforts. Under 80.613(d)(4), truck carriers can rely on sampling and testing conducted by another party, but must make other appropriate quality assurance efforts to meet this defense element. Parties other than tank truck carriers will need to conduct their own periodic sampling and testing, and will not be able to rely in whole on testing by parties upstream in the distribution system. 12.8: Will appropriate processes and QA/QC oversight be acceptable defenses against enforcement for off-spec product? Testing shows that the pipeline does not add sulfur from the steel. If base testing is done to identify protection volumes, and operational records support no accidental contamination, will this be sufficient? Could this preclude many proprietary and batched pipelines from needing on-line analyzers and extensive sampling process? A: Parties are presumed liable for a violation if a noncompliant fuel is found to be in their control, or if they are in the distribution system upstream of the facility where the violation is found. Downstream parties have a defense to presumptive liability if: (1) the party did not cause the violation; (2) PTDs establish that the fuel was in compliance while the fuel was under the party's control; and (3) the party conducted an adequate QA program, including sampling and testing. While refiners, importers and transmix processors are required to test each batch of product represented to meet the 15 ppm sulfur content standard, most downstream parties are not required to test every batch. Testing for downstream parties is voluntary. Downstream parties may conduct periodic sampling and testing for quality assurance purposes in order to establish a defense to liability for alleged violations. Each company should consider its distribution system and its own operations in determining the appropriate sampling and testing frequency. Factors that EPA believes are relevant include: the results of previous sampling; the volume of fuel in a particular shipment (the larger the volume, the greater the justification for testing); the degree of confidence in the quality of the product when it was received; and the opportunity for violations while the fuel was in possession of the party (e.g., the opportunity for commingling with higher sulfur product). For example, the volume of shipments into terminals are normally relatively large. A terminal that samples and tests after each receipt of 15 ppm sulfur content product will likely be able to meet its periodic sampling and testing defense element, and will have significant evidence regarding the "didn 7 cause " defense element as well. However, it should be noted that a terminal could demonstrate that all product received meets the applicable specifications, and still cause a violation to occur subsequent to receipt. Also note that there are variations to the defense elements for certain parties, such as parties who blend additives having a 73 ------- sulfur content exceeding 15 ppm to fuel subject to the 15 ppm standard. Note that the rule requires QC for sulfur measurement instrumentation. If instruments are out of control requirements, then all samples taken since the instrument was last in control must be retested. QC records must be retainedfor 5 years. 12.9: Will pipelines have an exempt refiner defense if higher than standard sulfur is located in their systems? A: The fuel sulfur level of a batch offuel must conform to the way it is designated. If a pipeline has fuel that is designated as 500 ppm or 15 ppm sulfur, and it does not meet the designated level, then it is noncomplying. It is not a defense to claim the fuel should have been designated otherwise by an upstream party. 12.10: What steps must a retailer/distributor take to assure that it is not liable for the sale of off-spec motor vehicle diesel fuel subject to the 15 ppm standard? A: As discussed in questions 4.35 and 12.18, retailers have certain affirmative requirements, including properly labeling pump stands, maintaining product transfer documents and records regarding downgrading of 15 ppm diesel fuel. Retailers must not cause the 15 ppm fuel to be contaminated by misdelivery of high sulfur product into a storage tank for 15 ppm sulfur content product. Retailers should carefully inspect product transfer documents at the time of delivery to assure that the proper product is being delivered into each storage tank. We believe that retailers and distributors should work closely together to assure that misdeliveries do not occur. The liability and defense provisions of the 15 ppm motor vehicle diesel rule are similar to those ofprevious fuels rules. Under § 80.613(a), a retailer and any distributor or carrier in the distribution chain are deemed liable for a violation found at the retail outlet (see § 80.612). A retailer will not be deemed in violation if it can show it did not cause the violation, and product transfer documents account for the fuel found to be in violation and indicate the violating product was in compliance with the 15 ppm sulfur standard when it was under the retailer's control. A distributor must also show that it did not cause the violation, that the product transfer documents account for the product and show that the product was in compliance when it was under the distributor's control. A distributor could cause a violation by various actions, including by misdelivery of high sulfur product or commingling high sulfur product with 15 ppm product in a storage tank or 74 ------- transport truck. To establish a defense, a distributor must also demonstrate that it has conducted a quality assurance program, including periodic sampling and testing of the fuel it transports and delivers (see § 80.613(d)). 12.11: Many retailer/distributors use common carriers, rather than their own trucks, to transport and deliver diesel. Under the diesel rule, what potential liability and defenses to liability are in place for common carriers? If a common carrier does not follow the supplier's or the retailer's location and/or delivery instructions, is the common carrier liable for the misdelivery or the retailer? A: As with other EPA fuels programs, the highway and nonroad diesel sulfur regulations utilize a presumptive liability structure. When a violation is found, the party who owns, leases, operates, supervises or controls the facility where the violation is found, and every party upstream of that facility, who supplied the fuel to the facility where the violation is found, is presumed liable, absent a complete defense to the violation. Under the hypothetical, initially both the carrier and the retailer would be deemed in violation. The carrier who delivers 500 ppm product to a retail outlet tank whenl5 ppm product has been ordered would not be able to establish it did not cause the violation, and thus would remain liable. The distributor who hired the common carrier would be liable if the product transfer documents and other paperwork demonstrated that 15 ppm product was ordered and 500 ppm product was delivered, and the distributor failed to take reasonable steps to address the situation. A retailer may establish its defense by 1) demonstrating it did not cause the violation; and 2) and demonstrating that product transfer documents account for the fuel found to be in violation and indicate that the violating product was in compliance with the standards. A retailer does not have to conduct a quality assurance sampling and testing program to meet its defense requirements. However, a retailer must check the product transfer documents and properly direct deliveries to the proper storage tank. In this hypothetical, the retailer may have been able to detect the misdelivery at the time of delivery if it had checked the PTD provided by the carrier. If the retailer does not check the PTD at the time the misdelivery occurs (and if doing so would have shown that a misdelivery had occurred), and sells the product as 15 ppm fuel, the retailer would not be able to establish a defense. 12.12: How about after-hours deliveries? Many retailers also are not open 24 hours a day and received diesel deliveries during the night while its stores are closed. If a misdelivery is made, what are the retailer's defenses? 75 ------- A: As discussed above, regardless when the delivery occurs, the retailer must properly direct deliveries, and it must check the product transfer documents. Where the retailer's employees will not be present during deliveries, both the retailer and the trucker should take special care to prevent misdeliveries. A product transfer document must be provided to the retailer with every transfer of custody or title of the diesel fuel. The retailer has the responsibility to check the transfer document to determine that fuel meeting the appropriate standards was delivered to the appropriate tank. Therefore, if a misdelivery is made after-hours, the retailer's employee should discover this misdelivery upon opening the outlet the following day through an inspection of the product transfer document left by the carrier (or possibly earlier if a transfer documents were received earlier). If the retailer did not cause the misdelivery, and it discovers the misdelivery through inspection of product transfer documents, and locks the pumps before any diesel fuel is sold, then it will not be held liable for the violation. Assuming the retailer properly instructed the distributor or carrier to deliver 15 ppm fuel to the appropriate storage tank, the carrier would not be able to establish a defense. The distributor would also be liable for a violation if the paperwork shows that a misdelivery was taking place (e.g., that 15 ppm fuel was ordered but 500 ppm fuel was being delivered). 12.13: Refiners will produce diesel fuel that meets the 15 ppm standard at the refinery gate. However, the rule mandates that the sulfur content remain at 15 ppm or below throughout the distribution system until it is dispensed into a vehicle's fuel tank. Assume the PTDs of the product are in order and properly identify the diesel as 15 ppm fuel, what potential liability could a retailer have if the batch has been contaminated — in the pipeline, at the terminal, or in the transport truck — so that the diesel received by the retailer exceeds the 15 ppm spec? A: In this case, a retailer would initially be presumed liable for the violation, but could establish a complete defense to liability if the PTDs account for the fuel in violation and show that the product was in compliance with the 15 ppm sulfur standard; and the retailer did not cause the contamination. There may be cases where an unscrupulous retailer purposely receives violating product delivered by "midnight drops. " In some cases no product transfer documents cover the product. The retailer in such cases would not be able to establish a defense, since it would have caused the violations, and since not all product would be covered by its product transfer documents. Once the retailer becomes aware that the sulfur content of diesel product subject to the 15 ppm standard exceeds the standard, it has an obligation to shut down its retail pumps affected by the contaminated product until the violation can be corrected. If it did not shut it off, it would be liable for selling or dispensing noncomplying diesel fuel. 76 ------- 12.14: There is no field testing equipment commercially available to measure accurately sulfur at these low levels and almost no retailers or wholesale purchaser consumers have the type of on-site laboratories to conduct the testing. Thus, a distributor conducting a quality assurance plan (QAP) would be forced to send a sample to an outside laboratory for analysis and may not receive the test results for 24 to 48 hours. By this point, most if not all of the off-spec fuel would have been sold by the retail outlets, making it impossible to correct the non-compliance. Shouldn't a retailers or wholesale purchaser consumers QAP under the 15 ppm motor vehicle diesel program be limited to examining PTDs? If not, how does EPA expect distributors to comply with this defense requirement? A: Retailers are not required to show an appropriate sampling and testing program to establish a defense to liability. See § 80.613(a)(l)(iii). However, distributors, including truck distributors, who take title to the gasoline and deliver product to their retail outlets, must conduct a quality assurance sampling and testing program. These requirements are the same as in other fuels rules. A truck distributor could rely, in part, on a proper quality assurance sampling and testing program conducted by the terminal. But since there may be opportunities for the trucker to obtain improper product (e.g., 500 ppm fuel instead of the 15 ppm fuel that was ordered), or commingle high sulfur products with 15 ppm product, or otherwise cause violations, sampling at locations downstream from the truck loading terminal would be appropriate. If a distributor must utilize an outside laboratory to obtain test results, and if it is impossible for the distributor to obtain results quickly, the periodic sampling and testing quality assurance program would still be useful in as much as it would show if any violations are occurring and based on those findings the distributor and retailer should act immediately to prevent future violations, and to remedy the present violation if it still possible to do so by shutting down the affected pump stands until the product meets standards. In this situation, if a violation occurred and is discovered through the quality assurance testing, the distributor and retailer may not be able to establish a defense to the violation based on the delayed test results. However, EPA may take any such unavoidable delay into account in its evaluation of the case. Moreover, the distributor could, as stated above, limit its exposure, by obtaining as many terminal test results as possible. Whether the distributor and retailer could meet the causation element andPTD element would depend on the specific facts. 12.15: What responsibility, if any, does a retailer have to "police" its customers to assure that they do not misfuel their vehicles — e.g., dispense 500 ppm diesel, if offered at the retail outlet, into a 2007 or newer heavy duty truck? In many cases, diesel retail outlets are large with multiple fueling locations and are staffed by entry level employees earning just over the minimum wage. Does EPA expect these employees to "police" customers at the retail outlet to assure that these customers are fueling properly? Also, please provide 77 ------- further clarification of the term "permit." at § 80.610(d)(1). For example, if a marketer tells a self service customer that he can't fuel with 500 ppm but the customer continues, is the marketer "permitting" the introduction of 500 ppm into a 2007 or newer model year vehicle requiring 15 ppm? When exactly is a marketer "permitting" misfueling? A: Under the regulations, no person shall "[i]ntroduce, or permit the introduction of, diesel fuel into model year 2007 or later diesel motor vehicles, and beginning December 1, 2010 into any diesel motor vehicle, which does not comply with the standards and dye requirements of § 80.520(a)and (b). " Nor shall any person "introduce or permit the introduction into model year 2007 vehicles, motor vehicle diesel fuel that is identified as other than diesel fuel complying with the 15 ppm sulfur standard.... " Nor shall any person cause another person to commit an act in violation of these prohibitions. 40 CFR § 80.610(d) and (e). Therefore, a retailer will be liable if it, or its employees, introduce noncomplying fuel into vehicles, or permit such introduction of noncomplying fuel into vehicles or cause another person to violate the stated prohibitions. A retailer must properly label pump stands and assure that product represented by product transfer documents as meeting the 15 ppm standard is delivered to the appropriate storage tanks, and that product subject to the 500 ppm sulfur standard is not delivered to such storage tanks. Moreover, a retailer should train its employees that may fuel diesel vehicles regarding these prohibitions and the pump stand labels and the corresponding labeling of filler inlets and dashboards on model year 2007 and later diesel vehicles. Because there may be many scenarios regarding how misfueling violations occur at retail facilities, a retailer's liability for misfueling that occurs at its facilities will be evaluated on a case-by-case basis. Where a retailer has made reasonable efforts to prevent self-service customers from misfueling (e.g., by cutting power to the pump as soon as the misfueling is perceived) and has not in any way caused the misfueling (e.g., through mislabeling pumps) the retailer would not be liable for "permitting" misfueling by a self-service customer. 12.16: What about intentional misfueling by a customer? In the past, as new fuels have been introduced in different parts of the country (CARB II Diesel in California; RFG in Milwaukee), negative reactions by customers has been significant. Given the fact that truckers may believe that use of 15 ppm diesel fuel will result in lower fuel economy, less power, or mechanical problems with engine seals, some portion of customers might refuse to purchase 15 ppm fuel for their new trucks. How can EPA expect a retailer to stop a customer from intentionally misfueling his or her 2007 truck? A: A retailer is not responsible for misfueling by the customer unless the retailer or its employees have introduced the fuel, or permitted or caused the violation. 78 ------- While intentional misfueling by a customer normally does not meet this criteria, there may be scenarios where retail outlet employees' actions or failure to act may permit or cause violations, even though the vehicle operator may actually dispense the fuel into the vehicle. We believe that responsible retailers will take reasonable actions to make misfueling less likely to occur at their retail outlets. For example, a retail employee could remotely shut off the fuel supply to a customer that it does see misfueling, and explain to the customer that the retailer cannot permit misfueling of vehicles at its stations since the retailer is potentially liable for such violations. 12.17: What about intentional misfueling by a fleet customer? For example, if a distributor's fleet customer orders a load of 500 ppm on-road diesel fuel, which the distributor delivers, and then the fleet customer intentionally fuels MY 2007 vehicles with the 500 ppm diesel, what is the distributor's potential liability? Does the distributor have the responsibility to "police" its fleet customers to assure there is no intentional misfueling? A: A distributor is not responsible for misfueling by fleet customers unless the retailer or its employees have introduced the fuel, or permitted or caused the violation. Intentional misfueling by a fleet customer normally does not meet this criteria. However, there may be scenarios where a distributor could be liable for permitting or causing misfueling violations by a fleet operator. For example a distributor who knows a fleet customer only has one diesel fuel storage tank, and knows that the fleet operator has model year 2007 or later vehicles, may be liable for permitting or causing misfueling if it delivers 500 ppm product to that customer's storage tank, even if the customer ordered the 500 ppm product. We believe distributors and carriers should work with retail andfleet customers to ensure that fuel is delivered to the appropriate storage tank. By "permitting" we mean that a retail station does not take reasonable actions to stop the intentional misfueling that it witnesses a customer perform. 12.18: With the 15 ppm maximum sulfur requirement (with the 2 ppm downstream testing adjustment under § 80.580(d)) applying at all levels of the distribution system, from refinery to retail outlets, how much service station, delivery truck, terminal testing and other quality assurance testing does EPA view as necessary to constitute a presumptive liability defense? A: A quality assurance program, including a sampling and testing program, is one of the defense elements under the presumptive liability scheme (see § 80.613(a)(1) and (d)). The liability and defense provisions under this rule are like those of other fuels rules. What constitutes a valid sampling and testing program varies depending on the type of party, as discussed below, and also varies depending on the particular circumstances involved. Factors that EPA believes are relevant in 79 ------- designing any sampling and testing program include: the results ofprevious sampling and testing; the volume offuel being handled by a facility and the volume of individual batches being processed by a facility (the greater the volume of a batch the greater the justification for sampling and testing that batch); the degree of confidence in the quality of the fuel received based on all circumstances; the opportunity for violations to occur while the fuel is in possession of the party (e.g., the opportunity for commingling of 15 ppm fuel with 500 ppm or high sulfur distillates); and the opportunity for misdeliveries of product. Retailers and wholesale purchaser-consumers- Retailers and wholesale purchaser-consumers are not required to conduct sampling and testing programs. See § 80.613(a)(l)(iii). However, during the period when storage tanks are being turned over from 500 ppm fuel to 15 ppm fuel, retailers should take steps to assure the product in the tanks meets the 15 ppm standard before making the fuel available for sale as 15 ppm fuel. Terminals and Pipelines- An acceptable periodic sampling and testing program for terminals will probably require sampling and testing after every receipt of product into a terminal storage tank, given the stringent sulfur standard, the potential substantial emissions consequences of violations, and the potential for contamination of product with high sulfur distillates (and especially in the early years of the program, high sulfur gasoline). Appropriate pipeline testing will depend on many factors, including the length of the pipeline, the nature of the product in the pipeline cycle on either side of the 15 ppm motor vehicle diesel fuel, the opportunities for contamination as product enters the pipeline or offloaded to terminals, etc. Carriers such as pipelines may, in addition to appropriate testing of their own, rely on testing by other parties, such as the refiners who deliver product to the pipeline. Distributors- Distributors of motor vehicle diesel fuel who take title to the fuel must conduct a periodic sampling and testing program as part of the quality assurance element of their defense to presumptive liability. The appropriate frequency of sampling would depend on the circumstances, as noted above. A truck distributor who delivers fuel to retail outlets may be able to rely on tests conducted by the terminal it loaded product from, if the sampling and testing program is properly performed, in order to show fuel picked up from the truck loading terminal met standards. However, if for example, the distributor delivers both 500 ppm product and 15 ppm product, periodic sampling at the distributor's facility (especially if the distributor has storage tanks) and at retail outlets it delivers to would be important. In addition, a truck distributor should employee procedures to prevent misdelivery of500 ppm product into 15 ppm product storage tanks, 80 ------- and to prevent contamination in delivery tanks. Truck Carriers- Under § 80.613(d)(4), a tank truck carrier may conduct certain other oversight activities in lieu of sampling and testing. Truckers should develop procedures to assure that 15 ppm sulfur content product they handle is not contaminated by higher sulfur products and to assure that 500 ppm fuel, or other high sulfur product, is not misdelivered into a storage tank for 15 ppm fuel. Truckers should have procedures to assure that high sulfur product is completely drained from a truck compartment and hoses before that truck compartment is used to carry 15 ppm motor vehicle fuel. Alternative oversight activities in lieu of testing include driver training; periodic review of records; providing drivers with specific information regarding which customers, and which storage tanks at customer's facilities, require fuel meeting the 15 ppm standard and which have 500 ppm fuel storage tanks (or nonroad storage tanks), etc. Truck carriers may also rely on the sampling and testing programs of other parties as part of their quality assurance program (e.g., sampling and testing conducted by their immediate supplier). Branded Re finers- A branded refiner must conduct a quality assurance sampling and testing program at branded retail outlets as one aspect of the quality assurance program defense element to branded refiner liability under § 80.612(a)(3). The branded refiner must assess the specific factors that apply to its branded retail outlets and the distribution systems that supply them in determining the appropriate sampling and testing rate. In addition to the factors listed above, branded refiners should also consider the historical compliance of branded facilities in a marketing area, and whether there is reason to believe that particular downstream facilities do not comply with contractually imposed requirements designed to prevent violations. Moreover, in the first year the 15 ppm standard is in effect, a relatively high sampling rate would probably be necessary to assure that retail tanks are successfully transitioned to 15 ppm fuel by September 1, 2006. In subsequent years, it may be appropriate to raise or lower this sampling rate, depending on the extent of compliance demonstrated by the program. In areas where problems are found, the sampling rate should be increased, and efforts should be made to discover the causes of the problems and correct those problems. The specific facilities where violations were found should be reinspected frequently. Refiners and Importer s- Under § 80.613(a)(l)(iv), a refiner or importer must conduct testing of every batch to meet the quality assurance periodic sampling and testing element of its defense to presumptive liability. 81 ------- See § 80.613(a)(1) (iv) and (v), and § 80.613(d)(2) for special situations. 12.19: Marketers frequently have disagreed with EPA actions regarding waivers or enforcement discretion with respect to the RFG program. Some have predicted on-road diesel supply shortages when this rule takes effect in 2006. If such supply disruptions — whether caused by underproduction; refinery, terminal, or pipeline problems; or, weather — do occur, what will EPA's reaction be? A: It is difficult to discuss possible enforcement discretion issues that may occur. However, we note that, especially after 2010, when all highway diesel fuel must meet the 15 ppm sulfur standard, we do not foresee any practical way to distribute motor vehicle diesel fuel having a sulfur content greater than 15 ppm into the motor vehicle diesel fuel market. Of course, we realize that temporary supply disruptions may occur due to an Act of God, or other unforeseeable event. The regulation, and the Agency's inherent discretion, provide mechanisms for EPA to consider whether a supply disruption is one for which relief is appropriate. However, we believe it would be very difficult now to address a variety of crises that may or may not occur in the future. 12.20: There will likely be significant adjustments for the diesel fuel distribution system to make to assure that 15 ppm highway diesel is available on-spec for truckers and other customers. The rule mandates that this fuel be distributed in mid-2006 despite the fact that the demand for this fuel will be sparse prior to 2007. Would EPA consider providing a period of enforcement discretion after mid-2006 for companies in the distribution chain if good faith efforts to meet the 15 ppm standard are made? A: The regulations created a 3-step implementation process that is expected to give all levels of the distribution system, including the retail outlet and wholesale pur chaser-consumer level, enough time to bring storage tanks into compliance in time to meet the regulatory deadlines. Refiners and importers must be in compliance with the 15 ppm standard by June 1, 2006. All facilities downstream of the refiner or importer, except retail and wholesale purchaser-consumer facilities, must be in compliance by July 15, 2006, if they choose to market 15 ppm fuel. Similarly, retailers and wholesale pur chaser-consumers must be in compliance by September 1, 2006, if they choose to market 15 ppm fuel. These entities downstream of the refinery have built-in flexibility in that they can continue to market 500 ppm fuel if they so choose until 2010. 12.21: With the recent buying and selling of refining and marketing assets, branded retail outlets may no longer be supplied by refineries with the same name. E.g., Refiner A may now have retail outlets with Refiner B's brand and Refiner A may not supply the outlets. Given this situation, EPA's branded retail defense requirements no longer seem 82 ------- appropriate. A: Branded refiner/importer liability under the regulations is not based on whether the branded refiner actually supplies the fuel to the retail outlet. Under § 80.612, any refiner or importer whose corporate, trade or brand name, or whose marketing subsidiary's corporate, trade or brand name appears at a facility where a violation occurs, is deemed liable for the violation and must establish its defense to branded refiner liability to avoid liability. 12.22: In the fuel marketing industry "branded" means an exclusive supply contract between the brand and the retail outlet. In this sense some stations are branded for gasoline but not for diesel even though the "brand sign" flies above the property. Does branded refinery liability apply to diesel fuel sold at such a station? A: Under § 80.612, if the brand name "appeared at a facility " where a violation occurred, the branded refiner would be liable under the branded refiner liability provisions. Where gasoline and diesel fuel are sold at a retail outlet on the same premises, and the facility is branded as defined by the regulation, the gasoline and diesel operations would generally be considered branded since they would usually be part of the same facility. 12.23: Where a branded jobber owns & supplies its branded retail outlet, who is potentially liable for violations found at the retail outlet and what quality assurance sampling and testing is the branded refiner and jobber/retailer responsible for? A: The branded refiner would be liable for any violation that occurs at the branded facility. To establish a branded refiner defense, the branded refiner must, among other things, establish that it had an appropriate quality assurance sampling and testing program. See questions 12.18 and 4.35 for liability and defense provisions for retailers and distributors. 12.24: For an owner of a retail outlet or a fleet fueling facility (a wholesale purchaser-consumer facility), if the product transfer documents account for all product in the storage tanks and show that the product is in compliance with the 15 ppm standard, am I still at risk for penalties? A: Where PTDs account for all product and show the product is in compliance with the diesel standards, and where the pumps are properly labeled, and the retailer or wholesale purchaser-consumer has not caused the violation, (e.g., has not misdirected noncomplying product into the 15 ppm diesel fuel storage tank or otherwise caused the contamination or misdelivery to occur) it will generally be able to establish its defense to liability. However, if for example, a retailer or wholesale purchaser-consumer were to purchase fuel that it has reason to believe does not comply with the 15ppm sulfur standard, even though the PTDs account 83 ------- for all product and state that the product does meet the standard, the retailer would be liable since it would have caused the violation. 12.25: During the lead phasedown in gasoline, EPA mandated that larger nozzles be installed on gasoline dispensers with leaded fuel and that restrictor plates be installed on the fill pipes of vehicles' fuel tanks, preventing the fueling of cars designed for unleaded gasoline with unleaded gasoline. Is EPA considering a similar alteration in nozzle sizes to prevent accidental or intentional misfueling under the 15 ppm diesel fuel program? A: We did not finalize any provisions beyondfuel pump labeling requirements. We recognized that some potential for misfueling would still exist and continued to discuss options in meetings and workshops with industry to explore simple, cost- effective approaches that couldfurther minimize misfueling potential. Through these discussions, however, no consensus was developed such that the magnitude of the potential misfueling problem wouldjustify the cost and burden associated with additional regulatory controls. 84 ------- 13. GPA/Small Refiners 13.1: EPA expanded the GPA (66 FR 19296). The GPA map on 66 FR 19300 is not consistent with the list of individual counties in Washington at 66 FR 19306. The map includes Klickitat County in the shaded area in Washington. However, the list of individual counties in Washington at § 80.215(a)(2)(i) does not include Klickitat County. Would you confirm that Klickitat County is in the GPA and your intention to include Klickitat County in a revised § 80.215(a)(2)(i)? A: In a direct final rule published on April 13, 2001 (66 FR 19296), we amended the Geographic Phase-in Area (GPA) to include counties and tribal lands in states adjacent to eight original GPA states. While Klickitat County appeared on the map on page 19300, it was inadvertently omitted from § 80.215(a) (2) (i) and should be included in the list of GPA counties. This inconsistency will be corrected in a future Federal Register notice. 13.2: A refinery approved by EPA to produce gasoline subject to the interim GPA standards in 2007 and 2008 must demonstrate that by June 1, 2006 it will produce enough 15 ppm highway diesel fuel to meet the minimum 85 percent of its baseline volume requirement. See § 80.594(c). When is this demonstration due for GPA refineries? Is this demonstration part of another report (i.e., the 2003, 2004 and 2005 pre-compliance reports) or is it a separate, stand-alone submission? A: Under § 80.594(c), a refiner or importer approved to produce gasoline in the GPA subject to the gasoline sulfur standards under § 80.540 must demonstrate that by June 1, 2006 it will be producing a volume of on-road diesel fuel containing 15 ppm sulfur or less that is equal to or greater than 85% of its baseline volume (see § 80.540(e)). Under § 80.540(b) the demonstration of future production volume required under § 80.594(c) was due December 31, 2001, with the application under § 80.540for approval of the gasoline sulfur extension. Under § 80.594(d), refiners and importers have until July 1, 2006 to submit a report stating that production or importation of 15 ppm sulfur motor vehicle diesel fuel started by June 1, 2006. The demonstration required by § 80.594(d) must be reported in a stand-alone report submitted by the refiner or importer. 13.3: 40 CFR 80.540(e) requires "The total volume of motor vehicle diesel fuel produced for use in the United States and designated as meeting the 15 ppm sulfur content standard under paragraph (d) of this section must meet or exceed 85% of the baseline volume established under paragraph (c) of this section, except that for the first compliance period from June 1, 2006 through June 30, 2007, the total volume must meet or exceed 92 percent of the baseline volume." Is it correct to assume that "produced" means available for sale at the refinery gate as an on-road fuel meeting 15 ppm diesel fuel standards? 85 ------- A: "Produced" should be interpreted as a refiner manufactured the motor vehicle diesel fuel from crude oil and the diesel fuel met all of the standards under § 80.520 and was designated as motor vehicle diesel fuel when it was delivered to the next facility in the distribution system. 13.4: What records must be kept to demonstrate that an adequate volume has been produced? A: Under § 80.540(i), the record keeping requirements specified under § 80.592 must be met for GPA gasoline. This includes records indicating the volumes of each batch of diesel produced during the compliance period (§ 80.592(b)). 13.5: How would a refinery with a loading rack account for 15 ppm diesel fuel that is sold into the offroad market? If production is interpreted in any other way, a refinery could be penalized if, due to logistical and production constraints, customers elect to purchase 15 ppm diesel fuel as an offroad diesel fuel. A: Per the requirements of § 80.598, promulgated in the nonroad diesel rule in June 2004, a refiner is responsible for designating the fuel appropriately when delivered to the next facility in the distribution system. Until June 2009, all 15 ppm diesel fuel must be designated as motor vehicle diesel fuel. 13.6: Who are the small refiners in the ULSD program? Are they the same as the "small refiners" in the Tier 2 gasoline program? A: We have received 18 applications for small refiner status, and many of these refiners are currently approved small refiners for the gasoline sulfur and highway diesel programs. However, they may not all be approvedfor NRLM small refiner status. Many of the refiners that applied. Specific information can be obtained upon request from Larry Haslett of EPA. 13.7: If a large refinery spins off a small refinery how long does the small refiner have to apply for the small refiner status? A: The dates to apply for small refiner status were specified in both rulemakings, and the deadlines have passed for both highway and nonroad diesel. 13.8: Is there an opportunity for a blender who is presently classified as a refiner to apply for small "refiner" status? A: No. The deadline to apply for small refiner status for both the highway and nonroad diesel fuel rules has passed. Furthermore, to be consideredfor small refiner status, a refiner must process diesel fuel from crude (see § 80.550 (a) and 86 ------- m 13.9: EPA indicated that the deadline for applying for small refiner status has already passed. However, should the marketer decide to blend e-diesel or biodiesel, it may want the option to be a "small refiner" under the diesel regulations. A: As stated in § 80.550 (a) and (b), the marketer would have to produce diesel fuel from crude. 13.10: How do you establish a baseline for a small refiner, who has never produced on road diesel but wants to delay low sulfur gasoline equipment and build low sulfur diesel equipment first? A: It was discussed in the preamble to the final highway rule to allow case-by-case looking at a variety of factors (see pages 50 73 and 5077, foot note). Unfortunately the provisions never made it into the regulations. We will be doing minor rule changes on this to mirror the preamble language. 13.11: Is the decision to use options 1, 2, or 3 irrevocable? A: Under 551(c)(3), we ask for "an indication" of which kind of relief small refiners expect to use. The regulations do not prevent a refiner from using a different option later. §80.553(h) voids the gasoline extension if small refiners fail to meet the 15 ppm volume requirements. 13.12: Is an independent auditor required in order to establish a diesel baseline? (See §§ 80.595(c)(2) and 80.92.) A: Yes an independent auditor is required to establish a diesel baseline. 13.13: A company owns 58.75% of our refinery. The refinery is rated at 260,000 Barrels/day of which the company owns 152,750 B/D (260 X 0.5875). Would this qualify our refinery for the small refiner hardship provisions? A: That ownership percentage makes the refinery a subsidiary under our definition (see § 80.550) and all of a subsidiary's crude capacity must be used in determining the total crude capacity. There is no prorating. 13.14: Can an approved highway diesel small refiner stay in business just by producing only 500 ppm diesel fuel and supply to the off road market. A: Yes. An approved highway diesel small refiner that currently produces highway diesel can produce no highway diesel and use all of its diesel fuel production to supply the nonroad market. 87 ------- 13.15: Our company is a small business refiner under the Small Business Administration (SBA) regulations. Our company would similarly meet the definition of a "small refiner" under the highway ULSD regulations, if not for the regulations' requirement that, for the purpose of determining qualification as a small refiner, a refiner must "include the employees and crude capacity of any subsidiary companies, any parent company and subsidiaries of the parent company in which the parent has 50 percent or greater ownership, and any joint venture partners." The distinction is attributable to the fact that, unlike the highway ULSD regulations, the SBA regulations do not affiliate our company with its owner. Under the SBA regulations, our company's size is determined by counting the total capacity of all of our refineries, and the employees of all of our refineries and subsidiary distribution businesses. However, Section 121.103(b)(2) of SBA's regulations exempts subsidiaries of our parent from affiliation, so that our company is not considered affiliated with the parent itself or other, unrelated subsidiaries of the parent. Our company believes that this definition is consistent with the purpose of the U.S. Environmental Protection Agency's affiliation rule, and is concerned that the provisions on affiliation in the highway ULSD regulations would inadvertently exclude our company. A: Under EPA 's gasoline anddiesel sulfur regulations, we include all employees and crude capacity of all parent companies and subsidiaries where the parent company maintains 50 percent (or greater) ownership (§ 80.550(a) and (c)). 88 ------- 14. Transmix/Interface Fuel 14.1: In the case where a terminal processes transmix with an on-site fractionator, is the on-road production volume subject to the requirements of § 80.520? A: The regulations finalized with the nonroad rule modified the requirements for transmix processors who do not also produce fuel from crude. These provisions, contained in § 80.513, allow for 100 percent of a transmix processor's highway production to remain at the 500 ppm sulfur level until June 1, 2010. 14.2: Interfaces between jet fuel and other distillates are cut into the other distillate to protect the jet fuel, thereby increasing the volume of the other distillate. Kerosene/15 ppm diesel fuel and high sulfur diesel/15 ppm diesel fuel interfaces could be cut into separate tankage to create 500 ppm on-road diesel (assuming no dye in the high sulfur diesel). Is there any limit as to the amount of 500 ppm on-road diesel that could be created through these interface cuts? Are there any special downstream requirements for the testing or documentation of on-road diesel created from interface? A: Under § 80.527(c), the maximum allowable amount of #2 15 ppm on-road diesel that can be downgraded to 500 ppm on-road diesel is 20%, otherwise there are no downgrade restrictions. However, on-road diesel created from interface must meet the standards under § 80.520. 14.3: How will EPA treat transmix, which does not fit into any category? It is not on-road and it is not off-road gas or fuel. Transmix is not intended for final use by any consumer but it can be re-refined or re-processed. a) For EPA purposes, will it need to be tracked after its creation? b) If it is sold to a refinery for re-refining, will EPA treat it differently than if it is sold to a reprocessor? c) Does it make a difference if it is sold to another refiner or the original refiner? A: a) Transmix would merely be designated as such and would not be tracked for EPA purposes unless (and until) it is redesignatedfor fuel use. b) It would not be treated any differently. However, transmix processors who are also refiners are held to different standards for the fuel that they produce from transmix. c) No, there is no difference if it is sold to another, or the original, refiner. 14.4: Can a terminal tank meet the 15 ppm diesel fuel sulfur standard on average, or must the diesel fuel meet the 15 ppm sulfur standard on a per-gallon basis? For example, if a pipeline or terminal accidentally cut some of an interface, consisting of 500 ppm diesel fuel and 15 ppm diesel fuel, into the 15 ppm diesel fuel, causing a certain strata of a 15 89 ------- ppm diesel fuel storage tank to exceed the 15 ppm standard, the rest of the tank may still contain product that continues to meet the 15 ppm standard. In the alternative, it may be possible to remedy a violation by blending diesel fuel exceeding 15 ppm sulfur content by blending sufficient quantity of very low sulfur product to make the tank or batch meet the 15 ppm standard. Would EPA allow such remedial action? A: Diesel fuel subject to the 15 ppm sulfur standard must meet that standard on a per-gallon basis and not on average. The pipeline or terminal must handle the interface in a manner that ensures that product distributed as subject to the 15 ppm cap is in compliance with that cap. If any portion of a tank that is offeredfor sale or supply as fuel subject to the 15 ppm sulfur cap is out of compliance with the 15 ppm cap then that volume offuel would be in violation. However, if a pipeline or terminal accidentally cuts part of an interface having a sulfur content greater than 15 ppm into a tank containing fuel subject to the 15 ppm sulfur standard, it may be possible to remedy the violation. We would not pursue an enforcement action where a terminal determines that product exceeding the 15 ppm standard has been added to a tank if the terminal: discovers the commingling of higher sulfur product with 15 ppm product through its quality assurance program and not by an EPA inspection; immediately locks down the tank before any of the product is released; transfers product exceeding the 15 ppm standard to some appropriate high sulfur product distribution; retests the 15 ppm product tank to assure that the entire remaining volume of the tank meets the 15 ppm standard before releasing the product as 15 ppm product; and maintains records demonstrating the occurrence, the actions taken to remedy the violation, sampling and test results, and actions to prevent future violations. Such situations may also be remedied by blending the contaminated product with low sulfur product in order to bring the sulfur level of all the product in the tank to the 15 ppm sulfur standard. Again, before releasing product the sulfur level should be retested, and records of the occurrence, remedial actions, sampling and test results, and of actions to prevent future violations should be maintained. Finally, such situations could be remedied by downgrading the entire volume of product affected by the commingling with the higher sulfur interface. When 15 ppm product is downgraded, the party should document the circumstances that gave rise to the downgrading. The diesel fuel in question should be segregated from diesel fuel subject to the 15 ppm standard, the product transfer documents must reflect the downgraded classification, and the diesel fuel must not be sold, dispensed or transported in a manner that is inconsistent with the downgraded classification. 90 ------- 15. General/Miscellaneous 15.1: Why is heating oil exempt from the sulfur content regulations? If it's bad for cars, why not for people's homes? A: The Clean Air Act does not give EPA specific authority to regulate heating oil. 15.2: Will there be any significant quantities of kerosene that get hydrotreated to 15 ppm (or lower) sulfur for making ULSD? A: We did not require early reporting of this information in the pre-compliance reports, and as such do not have data specific to address it. Nevertheless, we are currently aware that at least two refiners plan on manufacturing 15 ppm #1 diesel fuel for wintertime blending purposes. 15.3: What does EPA intend to do with all of these reporting requirements and paperwork to justify their cost to the consumer and taxpayer? A: The D&T and recordkeeping provisions were put in place as a means of reducing the capital and operating costs otherwise necessary to segregate fuels. The costs of these provisions were estimated in the draft Information Collection Request (ICR) submitted to OMB, and are small in comparison to the overall costs and benefits of the program. 15.4: Cetane index does not work for alternative diesel formulations- diesel with 10% ethanol must be tested by Cetane number. Do you plan to make a technical correction? A: Only the highway diesel rule contains a cetane index standard. We will make a technical amendment to the regulations, if necessary, to address this issue. 15.5: Does "other sources of volume" refer to diesel desulfurizers? What do you mean by "produced from crude oil"? A: "Other diesel fuel" means any distillate products that meet the definition of diesel fuel, such as kerosene, that is represented to have a sulfur content less than or equal to 500ppm. "Producedfrom crude oil" means that the refiner manufactured the diesel fuel from crude oil, typically through distillation and hydroprocessing. 15.6: If terminals opt to wash barges, tanks, equipment and trucks before running 15 ppm diesel fuel through their systems, the flushing process will generate substantial volumes of oily-water waste. Has the EPA given thought to assisting the industry in dealing with this waste? 91 ------- A: The highway diesel rulemaking did not specifically address this issue. The rulemaking allowed terminals until July 15, 2006 (approximately 6 weeks after the June 1, 2006 compliance date for refiners and importers), before any 15 ppm highway diesel fuel they distribute must meet the 15 ppm standard, and this additional time should help to minimize waste. 15.7: Public reaction to new fuels in the past has been mixed (i.e., RFG in Milwaukee, CARB II Diesel in California). What steps does EPA intend to take to educate and inform owners of diesel-powered motor vehicles of the changes to fuel specifications, performance issues, and/or air quality benefits? A: EPA currently has all documents associated with the diesel fuel rules available on its website (http://www. epa. eov/cleandiesel/) and will be periodically providing additional updates to the website to provide summary descriptions for the public of the benefits and impacts of the rules. Additional steps will be determined over the course of the remaining months leading up to June 2006. 15.8: In the past, EPA has, with the assistance of industry trade associations, produced fuels brochures for use at retail outlets explaining new fuel programs and addressing performance and air quality issues. Is EPA planning a similar effort with respect to the diesel fuel programs? A: Actions such as these were discussed with industry during the rule development. We have been, and will continue to, work with industry trade associations over the next several years on such actions. 92 ------- |
