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 collection of claims alleging the operator violated the US Clean Air Act (CAA) and associated state air pollution management legal guidelines by illegally emitting hundreds of tonnes of harmful pollution by way of flaring at three of its Texas petrochemical manufacturing vegetation.
As a part of the Mar. 9 judicial settlement, Chevron Phillips signed a consent decree lodged within the Southern District Court of Texas beneath which the operator has agreed to spend an estimated $118 million to finish necessary pollution-controlling upgrades and implement air-quality monitoring techniques at its Port Arthur, Sweeny, and Cedar Bayou crops situated in Port Arthur, Sweeny, and Baytown, Tex., respectively, EPA and DOJ stated.
Designed to enhance Chevron Phillips’s flaring practices and compliance—an EPA priority beneath its Creating Clean Air for Communities National Compliance Initiative—the proposed consent decree requires the operator to minimize back flaring by minimizing the volume of waste gas sent to the flares. Chevron Phillips also should improve combustion efficiency of its flares for when flaring is critical, EPA said.
The operator additionally pays a $3.4-million civil penalty for the previous violations no later than 30 days after the effective date of the consent decree that—currently inside its 30-day public remark period scheduled to finish on Apr. 14—still remains subject to last courtroom approval, in accordance with a Mar. 15 discover in the Federal Register.
Once Chevron Phillips fully implements air pollution controls at the three Texas chemical plants 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 more than 75,000 tonnes/year (tpy). The settlement also should end in decreased emissions of unstable 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 stated.
The March settlement arises from EPA’s unique complaint against Chevron Phillips, in which the agency alleges the operator, at various time between 2009 and the present, performed improperly reported, unreported, and-or unpermitted modifications at 18 flares located across the Port Arthur, Sweeny, and Cedar Bayou vegetation, triggering a chain of CAA-related noncompliance infractions, together with violations of:
New supply review (NSR) requirements for newly constructed and modified sources of criteria air pollutants.
Title V allowing necessities for NSR violations.
Federal new source efficiency normal (NSPS), nationwide emission standards for hazardous air pollution (NESHAP), and most achievable management technology (MACT) necessities included into the Title V permit related to monitoring to ensure flares are operated and maintained in conformance with their design.
NSPS, NESHAP, and MACT necessities integrated into the Title V allow associated to working flares consistent with good air pollution management practices.
NSPS, NESHAP, and MACT requirements incorporated into the Title V allow associated to combusting fuel in flares with a net heating value (NHV) of 300 BTU/scf or larger.
Specifically, EPA alleges Chevron Phillips failed to properly operate and monitor the chemical plants’ industrial flares, which resulted in extra emissions of toxic pollution at the website. The grievance moreover claims the operator frequently oversteamed the flares and has did not comply with different key operating constraints to ensure VOCs and HAPs contained in flare-bound gases are effectively combusted.

Per the consent decree, Chevron Phillips has agreed to the next measures to reduce the quantity of waste gasoline despatched to flares at the Texas crops:
At Cedar Bayou, the company will function a flare gas recovery system that recovers and recycles gases instead of sending them for combustion in a flare. The system will permit the plant to reuse these gases as an internal fuel or a product on the market.
At Port Arthur and Sweeny, Chevron Phillips might be required to amend its air high quality permits to limit the flow of gasoline at selected flares.
The company additionally will create waste minimization plans for the three vegetation which will further reduce flaring.
For flaring that must happen, Chevron Phillips will install and function devices and monitoring techniques to ensure that the gases sent to its flares are efficiently combusted.
The company may also surround each of the three covered plants at their fence strains with a system of monitors to measure ambient levels of benzene—a carcinogen to which persistent exposure can cause quite a few well being impacts, together with leukemia and antagonistic reproductive results in women—as well as post these monitoring outcomes via a publicly available website to supply neighboring communities with more details about their air high quality.
If fence-line monitoring data indicates excessive levels of benzene, Chevron Phillips will conduct a root cause evaluation to find out the source and take corrective actions if emissions exceed certain thresholds.
According to the consent decree, however, Chevron Phillips already has undertaken a series of actions to reduce flare-related emissions at the trio of crops. These embody:
At all three crops, equipping every coated flare with smaller assist-steam controls (to optimize assist-steam injection at low waste-gas move rates); implementing flare stewardship metrics (to reduce flaring); and optimizing course of unit procedures and operations (to reduce flaring).
At Cedar Bayou, changing supplies for flare sweep gas from nitrogen to plant gas gas, resulting in reduced use of supplemental fuel use and lowered emissions.
At Port Arthur, changing the kind of catalyst utilized in acetylene converters, resulting in longer cycle occasions between regenerations and decreased emissions.
At Port Arthur, switching the fabric for multiple dryer regenerations from nitrogen to a course of fluid with the next NHV, resulting in lowered use of supplemental gasoline and decreased emissions.
Environmental justice prioritized
The newest Tweet by Bloomberg states, ‘Despite surging gasoline prices, there could by no means be a brand new refinery built in the united states as policymakers transfer away from fossil fuels, Chevron CEO says.
“We haven’t had a refinery constructed in the United States for the reason that Seventies,” Chief Executive Officer Mike Wirth said in an interview on Bloomberg TV. “My personal view is there will by no means be one other new refinery constructed in the United States.”
The Biden administration has appealed to OPEC and the U.S. shale producers to pump extra crude to assist decrease gasoline prices this 12 months. But even if oil costs had been to fall, the us may not have enough refining capacity to the meet petroleum product demand. Refining margins have exploded to historically excessive ranges in latest weeks amid decrease product provides from Russia and China and surging demand for gasoline and diesel.
And including refining capability just isn’t easy, especially within the present surroundings, Wirth stated.
“You’re looking at committing capital 10 years out, that will want decades to supply a return for shareholders, in a policy environment where governments around the globe are saying: we don’t need these merchandise,” he mentioned. “We’re receiving combined signals in these policy discussions.”
U.S. retail gasoline prices averaged $4.76 a gallon today, a report 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 ranges for this time of yr since the early Nineteen Nineties, raising the specter of gas rationing, simply as the united states enters summer driving season. Even with excessive costs, Wirth is seeing no indicators of shoppers pulling again.
“We’re nonetheless seeing real power in demand” regardless of international air travel and Chinese consumption not yet back to their pre-pandemic levels, Wirth said. “Demand in our business tends to move quicker than supply in both instructions. We noticed that in 2020 and we’re seeing that at present.”
Chevron couldn’t instantly increase production right now even when it needed to as a end result of appreciable lead times in bringing on oil and fuel wells, even in the short-cycle U.S. shale, Wirth stated. The CEO expects to satisfy with the Biden administration when he’s in Washington next week.
“We need to sit down and have an sincere dialog, a practical and balanced dialog in regards to the relationship between vitality and financial prosperity, nationwide security, and environmental protection,” Wirth said. “We need to acknowledge that every one of these matter.”
