EPA plans audit of renewable fuel credit system
US environmental regulators are stepping up efforts to root out fraud in the trading of renewable fuel blending credits that some small refiners have called a drag on the industry.
The Office of Inspector General for the US Environmental Protection Agency (EPA) plans to audit trading of invalid Renewable Identification Numbers, a type of credit used to signify compliance with federal fuel blending standards, according to an EPA letter dated 17 September.
RIN credits, which are generated when renewable fuels are blended with traditional fuels for the US transportation supply, have been the subject of controversy since they were introduced as part of the Renewable Fuel Standard in the mid-2000's. Small independent refiners, which typically lack blending capabilities, have alleged the credits disproportionately affect them, while stakeholders on all sides of the issue have called for more transparency into RIN generation, trading and regulation.
In the audit, the EPA inspector will evaluate whether the agency's Moderated Transaction System used to verify RIN trades includes "controls to identify and reduce the generation and trading of invalid RINs."
The US over the past decade has successfully prosecuted a number of RIN fraud cases.
The EPA's latest probe into RIN trading was identified earlier this year as one measure the agency could use to ensure better data reliability as part of its fiscal year 2021 oversight plan. The inquiry comes at a time when rising prices for credits have prompted some obligated parties to step away from the market, while political calls for reformation of the credit system continue to increase.
Prices for RINs, as reflected by the Argus-assessed Renewable Volume Obligation (RVO) benchmark, reached all-time highs this summer, topping 20¢/USG, amid uncertainty about how the new administration of President Joe Biden planned to handle renewable fuel mandates after a raft of lawsuits from US refiners and biofuel interests. The RVO so far this month has averaged 16.08¢/USG, down from the recent record but still more than triple the price 16 months ago and more than five times the average price in 2019.
Several refiners, including Delek, have called RIN credits an "overhang on the industry." Delta Airlines, owner of the 185,000 b/d Trainer refinery outside Philadelphia, Pennsylvania, responded in July to a question about its RIN obligations by saying it was not planning to "spend good cash chasing a marketplace that isn't transparent."
The credit compliance system is also a hot-button political issue in states with strong refining and union interests, as well as those with the agricultural interests backing renewable fuels production. On 16 September, Pennsylvania lawmakers wrote a letter to President Biden claiming that the Trainer refinery's operators will be required this year to "spend twice as much to comply with the RFS program as it spent to purchase the entire company only ten years ago," in a plea to the White House to provide the EPA "with a stronger hand in stabilizing RINs pricing."
Conversely, biofuel lobby Growth Energy in a letter today asked the EPA to set "ambitious" biofuel blending targets when it updates RFS blending obligations later this year.
This is not the first time potential RIN fraud has come under the eye of US oversight bodies. In 2019, the US Government Accountability Office drew attention to "opportunities for fraud" in the trading of computerized RIN numbers, such as the double counting of RINs or generation of RINs for biofuels that do not exist.

EPA already at work on 2026-forward RFS rules
Monterey, 17 September (Argus) — The Environmental Protection Agency (EPA) has started work on the second set of rules for the Renewable Fuel Standard (RFS), expected to span multiple years beginning in 2026, a spokesperson said today. The rule will likely establish renewable volume targets for multiple years under the RFS, although the exact timeframe has not been confirmed, EPA deputy office director Ben Hengst said today at the Argus North American Biofuels, LCFS and Carbon Summit in Monterey, California. Work on the incoming rule was originally not expected to begin until early 2025. Updated analysis, especially regarding advanced biofuels and feedstocks, will inform new rulemaking, as well as the inclusion of regulatory changes intended to improve the program's implementation, Hengst said. Unprecedented growth in US biofuels imports led overall advanced biofuel supply in 2023 to far surpass EPA projections. But biomass-based diesel volumes for the current rules were based on projected growth in North American feedstock supply — not international availability nor the nameplate capacities of US refineries, Hengst said. There were also large increases in imported feedstocks for biofuel production, namely in used cooking oil and tallow. But the potential for an upset in global trade flows remains an agency concern. Domestic policy in some countries could boost offshore consumption of feedstocks and finished fuels that have arrived to the US market in recent years, while the US policy environment itself remains vulnerable to change. The EPA is also navigating recent adverse judgments against its interpretation of the Small Refinery Exemption program and is prioritizing the development of options that would comply with court orders. There was no clarity provided on eRINs as the EPA continues to consider its options. By Jasmine Davis Send comments and request more information at feedback@argusmedia.com Copyright © 2024.

US regulatory clarity vital to sustain biofuels growth
US regulatory clarity vital to sustain biofuels growth
Monterey, 17 September (Argus) — Clarity from both US state and federal regulators regarding the rules and incentives for biofuels production is essential to ensure continued growth to achieve underlying carbon-reduction targets, industry stakeholders said today. A lack of guidance for incentive programs and qualifications for 2025 and beyond is already hindering trade and investment in key US biofuels markets, panelists said today at the Argus North American Biofuels, LCFS and Carbon Summit in Monterey, California. The current biodiesel tax credit (BTC) is scheduled to give way to the Inflation Reduction Act's Clean Fuels Production Credit (CFPC) in January, while narrowed proposed targets and credit qualifications in state Low Carbon Fuel Standard (LCFS) programs has effectively left key portions of the biofuels market in a holding pattern. Alignment and certainty between regulatory bodies on what will be incentivized and credited in the future will be an essential component of business and investment decisions in the industry, necessary to reach ambitious carbon-reduction targets within the next decade. "The fact that we don't have clarity mid-September for a tax credit going into effect on 1 January, is really hard to believe," said Kurt Kovarik, vice president of federal affairs for Clean Fuels Alliance America. "No one knows the rules of the road with respect to 45Z." Panelists echoed opposition to proposed California caps on crop-based renewable feedstocks that discussed on Monday at the conference during sustainable aviation fuel (SAF) discussions. "If the goal is to remove carbon, the extent to which we can base it on science and not pick winners and losers is in everyone's interests," Kovarik said. "All you're going to end up doing is limiting the driving out of carbon." But speakers today further warned of the potential for a duplication of efforts by parties trying to satisfy both state LCFS programs and the federal Renewable Fuel Standard program. Proposed requirements may also require an unprecedented level of collaboration between segments of the US renewables supply chain. Those requirements could be more disruptive than the feedstock cap itself and potentially have the greatest limiting effect on fuel supply into California, said Don Gilstrap, Chevron's manager of fuels regulations. With that goal in mind, declining carbon intensity targets are already providing the necessary incentive for producers to pivot away from crop-based renewable feedstocks, Gilstrap said. But panelists were optimistic about rising interest in replicating LCFS-style focuses on carbon intensity — an approach they theorized would "unleash innovation" across both the finished fuels and feedstocks segments of the industry.

USCG updates ongoing lower Mississippi restrictions
USCG updates ongoing lower Mississippi restrictions
Houston, 17 September (Argus) — The US Coast Guard (USCG) will further limit northbound movement for barges transiting the lower Mississippi River despite slightly higher water levels following Hurricane Francine's landfall late last week. The USCG announced on 16 September that all northbound traffic traveling from Tunica, Mississippi, to Tiptonville, Tennessee, can only have five barges wide and only four of those can be loaded. Barges also cannot be loaded deeper than 9.5ft. Any southbound traffic from Vicksburg, Mississippi, to Tunica cannot move more than seven barges wide or be drafted deeper than 10.5ft. Southbound traffic from Tiptonville to Tunica can only be six barges wide or less and cannot have a draft greater than 10ft. The USCG has updated lower Mississippi river draft restrictions about four times since the end of August, but this is the third year in a row of notable low water for the fall on the lower Mississippi river which has triggered draft restrictions to arrive more quickly than previous years. Hurricane Francine brought significant rainfall to the lower Mississippi at the end of last week . But this has not eased the minds of mariners, who anticipate the water may leave as quickly as it arrived.

California regulator floats future LCFS linkage
California regulator floats future LCFS linkage
Monterey, 17 September (Argus) — California would welcome bringing US low-carbon fuel standard (LCFS) programs together in a common market, one of the state's top regulators said on Tuesday. Such a linkage is unlikely to occur in the near future, but California Air Resources Board (CARB) deputy executive director Rajinder Sahota said it is something worth pursuing. "I totally think we should link our LCFS programs," she said at the Argus North American Biofuels, LCFS and Carbon Markets Summit in Monterey, California. Sahota said California and other LCFS states are working on a system that could allow the trading of compliance credits between companies covered by each program, but did not provide any other details. Her comments mark a change in tenor from CARB, which historically has said a linkage would be difficult given the differing starting points and carbon intensity targets of each program. Oregon's Clean Fuels Program (CFP) started five years after California's LCFS, while Washington launched its Clean Fuel Standard just last year. New Mexico is working on its own program that will begin by 2026. Oregon and Washington regulators at the conference said there have not been any formal discussions about a linkage, but did not completely dismiss the idea, highlighting the close informal coordination between the states. "All puzzles can be solved eventually," said Bill Peters, interim director of the CFP. By Michael Ball Send comments and request more information at feedback@argusmedia.com Copyright © 2024.
