Chevron Phillips Chemical Co. has reached a settlement with the US Environmental Protection Agency (EPA) and the US Department of Justice (DOJ) to resolve a sequence of claims alleging the operator violated the US Clean Air Act (CAA) and related state air air pollution control legal guidelines by illegally emitting thousands of tonnes of dangerous pollution through flaring at three of its Texas petrochemical manufacturing vegetation.
As part of the Mar. 9 judicial settlement, Chevron Phillips signed a consent decree lodged in the Southern District Court of Texas underneath which the operator has agreed to spend an estimated $118 million to finish essential pollution-controlling upgrades and implement air-quality monitoring systems at its Port Arthur, Sweeny, and Cedar Bayou plants located in Port Arthur, Sweeny, and Baytown, Tex., respectively, EPA and DOJ said.
Designed to enhance Chevron Phillips’s flaring practices and compliance—an EPA priority under its Creating Clean Air for Communities National Compliance Initiative—the proposed consent decree requires the operator to reduce flaring by minimizing the volume of waste fuel despatched to the flares. Chevron Phillips also should enhance combustion efficiency of its flares for when flaring is critical, EPA mentioned.
The operator also pays a $3.4-million civil penalty for the past violations no later than 30 days after the efficient date of the consent decree that—currently within its 30-day public remark period scheduled to end on Apr. 14—still stays topic to final court docket approval, based on a Mar. 15 discover within the Federal Register.
Once Chevron Phillips absolutely implements air pollution controls on the three Texas chemical vegetation as required by the consent decree, EPA estimates emissions of climate-change-causing greenhouse gases (GHGs)—including carbon dioxide (CO2), methane, and ethane—will fall by greater than 75,000 tonnes/year (tpy). The settlement additionally ought to lead to decreased emissions of risky natural compounds (VOCs) by 1,528 tpy, of nitrogen oxides by 20 tpy, and of hazardous air pollution (HAPs)—including benzene—by 158 tpy, EPA said.
The March settlement arises from EPA’s authentic grievance against Chevron Phillips, by which the agency alleges the operator, at varied time between 2009 and the current, carried out improperly reported, unreported, and-or unpermitted modifications at 18 flares positioned throughout the Port Arthur, Sweeny, and Cedar Bayou plants, triggering a chain of CAA-related noncompliance infractions, including violations of:
New source evaluate (NSR) necessities for newly constructed and modified sources of criteria air pollution.
Title V allowing requirements for NSR violations.
Federal new source performance normal (NSPS), nationwide emission standards for hazardous air pollutants (NESHAP), and maximum achievable management expertise (MACT) requirements incorporated into the Title V permit associated to monitoring to ensure flares are operated and maintained in conformance with their design.
NSPS, NESHAP, and MACT requirements incorporated into the Title V allow associated to operating flares according to good air pollution management practices.
NSPS, NESHAP, and MACT necessities integrated into the Title V permit associated to combusting fuel in flares with a internet heating value (NHV) of 300 BTU/scf or higher.
Specifically, EPA alleges Chevron Phillips did not properly operate and monitor the chemical plants’ industrial flares, which resulted in extra emissions of poisonous air pollution on the web site. The criticism moreover claims the operator frequently oversteamed the flares and has failed to adjust to different key working constraints to ensure VOCs and HAPs contained in flare-bound gases are efficiently combusted.
Specific upgrades, implementations
Per the consent decree, Chevron Phillips has agreed to the next measures to minimize back the quantity of waste fuel sent to flares on the Texas vegetation:
At Cedar Bayou, the corporate will operate a flare fuel restoration system that recovers and recycles gases instead of sending them for combustion in a flare. The system will allow the plant to reuse these gases as an inside fuel or a product for sale.
At Port Arthur and Sweeny, Chevron Phillips will be required to amend its air high quality permits to restrict the flow of gas at selected flares.
The firm also will create waste minimization plans for the three crops that may additional cut back flaring.
For flaring that should happen, Chevron Phillips will set up and operate devices and monitoring systems to guarantee that the gases sent to its flares are effectively combusted.
The firm may even surround every of the three lined plants at their fence lines with a system of screens to measure ambient levels of benzene—a carcinogen to which continual exposure could cause quite a few health impacts, together with leukemia and opposed reproductive effects in women—as nicely as post these monitoring results by way of a publicly out there web site to supply neighboring communities with extra information about their air quality.
If fence-line monitoring information indicates excessive levels of benzene, Chevron Phillips will conduct a root cause analysis to determine the supply and take corrective actions if emissions exceed sure thresholds.
According to the consent decree, however, Chevron Phillips already has undertaken a collection of actions to scale back flare-related emissions at the trio of vegetation. These include:
At all three crops, equipping each covered flare with smaller assist-steam controls (to optimize assist-steam injection at low waste-gas flow rates); implementing flare stewardship metrics (to reduce flaring); and optimizing process unit procedures and operations (to reduce flaring).
At Cedar Bayou, changing supplies for flare sweep gasoline from nitrogen to plant gasoline gas, leading to decreased use of supplemental gas use and reduced emissions.
At Port Arthur, changing the sort of catalyst used in acetylene converters, leading to longer cycle instances between regenerations and reduced emissions.
At Port Arthur, switching the fabric for multiple dryer regenerations from nitrogen to a course of fluid with a better NHV, leading to decreased use of supplemental gasoline and reduced emissions.

The latest Tweet by Bloomberg states, ‘Despite surging gasoline prices, there could by no means be a new refinery in-built the united states as policymakers move away from fossil fuels, Chevron CEO says.
“We haven’t had a refinery built within the United States for the reason that Nineteen Seventies,” Chief Executive Officer Mike Wirth said in an interview on Bloomberg TV. “My private view is there’ll by no means be one other new refinery built in the United States.”
The Biden administration has appealed to OPEC and the us shale producers to pump extra crude to assist decrease gasoline prices this year. But even when oil prices had been to fall, the us might not have sufficient refining capability to the meet petroleum product demand. Refining margins have exploded to traditionally excessive levels in current weeks amid decrease product provides from Russia and China and surging demand for gasoline and diesel.
And adding refining capability isn’t straightforward, especially within the current setting, Wirth mentioned.
“You’re taking a glance at committing capital 10 years out, that will want a long time to offer a return for shareholders, in a coverage environment the place governments all over the world are saying: we don’t want these merchandise,” he said. “We’re receiving combined signals in these coverage discussions.”
U.S. retail gasoline costs averaged $4.seventy six a gallon right now, a record high and up 45% this 12 months, in accordance with AAA. East Coast stockpiles of diesel and gasoline inventories within the New York-region are at their lowest levels for this time of year for the explanation that early Nineties, elevating the specter of gas rationing, simply as the us enters summer season driving season. Even with excessive costs, Wirth is seeing no indicators of consumers pulling again.
“We’re still seeing actual power in demand” despite worldwide air travel and Chinese consumption not yet back to their pre-pandemic levels, Wirth stated. “Demand in our business tends to maneuver faster than provide in each directions. We noticed that in 2020 and we’re seeing that right now.”
Chevron couldn’t immediately enhance manufacturing at present even when it needed to as a outcome of considerable lead occasions in bringing on oil and gasoline wells, even in the short-cycle U.S. shale, Wirth mentioned. The CEO expects to meet with the Biden administration when he’s in Washington next week.
“We need to sit down down and have an sincere dialog, a pragmatic and balanced conversation about the relationship between energy and financial prosperity, national safety, and environmental protection,” Wirth said. “We need to recognize that each one of those matter.”
