NEXT Renewable Fuels, Inc

NEXT Renewable Fuels Oregon, LLC., also known as NXT Clean Fuels and referred to as NEXT, is proposing to construct a renewable diesel and sustainable aviation fuel manufacturing facility at the Port of Columbia County's Port Westward Industrial Park in Clatskanie.

The proposed facility will receive and process a variety of organic waste materials, such as used cooking oil, animal tallow and fish grease to produce the fuel products that work just like their petroleum-based equivalents. NEXT expects to have the production capacity of up to 50,000 barrels (1.58 million gallons) of clean fuel per day at full capacity. Renewable fuel products will be shipped offsite via pipelines, trucks and railcars, pending market conditions. NEXT anticipates that construction of this facility will begin in 2025, dependent on regulatory permit approvals. 

Public engagement

DEQ held a virtual public hearing on Oct. 8, 2024 to share information, accept verbal comments and answer questions about NEXT's draft 401 Water Quality Certification. Learn more about the proposed facility, how to provide comment and how DEQ regulates NEXT below.

DEQ is accepting public comments until Friday, Oct. 25, 2024, at 5 p.m. DEQ gives equal weight to written comments submitted online via Your DEQ Online, email at 401PublicComments@deq.oregon.gov or by mail and verbal comments made during the public hearing. DEQ will review and consider all comments received. Following consideration of public comment, the certification may be issued as proposed, modified or denied.

Please see the Public Notice for the draft 401 Water Quality Certification for more information about the proposed action and how to submit a comment.

In September 2021, DEQ held a public information session that reviewed all environmental permits required for NEXT to construct and operate its facility. DEQ also asked for input from attendees on what the agency should consider as it began working on these permits.

Water quality permits 

NEXT previously requested a 401 Water Quality Certification as part of the federal 404 authorization process, which is administered by the U.S. Army Corps of Engineers. The 404 water quality authorization program regulates projects happening in waters of the United States, including wetlands. The state-issued 401 certification is a required step of the federal 404 permitting process, which NEXT must complete for the project to move forward.

DEQ denied the 401 certification without prejudice in 2021 and 2022 due to insufficient information to evaluate the permit application. A denial without prejudice is an administrative denial that allows an applicant to resubmit an application for a 401 certification. NEXT resubmitted a request for a 401 Water Quality Certification to DEQ in January 2024. This started the one-year time period for DEQ to make a decision, according to U.S. EPA Clean Water Act rules.

NEXT Renewable Fuels will also need to apply for two stormwater discharge permits, which it must obtain for the project to move forward. NEXT needs to apply for a construction stormwater discharge general permit, which regulates how stormwater is managed during construction of the facility. NEXT must also apply for an industrial stormwater discharge general permit, which regulates how the facility manages its stormwater while operating.


DEQ held a questions and answers section during the public hearing about NEXT's draft 401 Water Quality Certification. This document​ is a comprehensive list of questions that were asked and DEQ's answers to those questions. ​

Q. What does a 401 Water Quality Certification do?

A. Section 401 of the Clean Water Act requires federal agencies to obtain a water quality certification from the state if the proposed activity may result in a discharge (including dredge and fill materials) to surface waters. The certification states that the discharge will comply with applicable sections of the Clean Water Act, including state water quality standards. It is required part of the U.S. Army Corps of Engineers federal 404 permitting process. The federal 404 permit cannot be issued until a 401 Water Quality Certification from the state is received. The U.S. Army Corps of Engineers is the lead agency for making 404 permit determinations.

Q. How does a 401 Water Quality Certification manage potential risks or impacts to the water?

A. The 401 Water Quality Certification has several tools available to ensure that a project meets state water quality standards. A 401 Water Quality Certification includes conditions that require the applicant to follow best management practices and perform monitoring to ensure that water quality standards are met. If there are unavoidable impacts to waterways and/or wetlands, projects are required to provide mitigation for the loss of water quality functions. Applicants may either submit a mitigation plan or purchase mitigation credits from an approved mitigation bank. The Oregon Department of State Lands and U.S. Army Corps of Engineers are responsible for overseeing the details and implementation of the mitigation plan.

For this project, NEXT is proposing a mitigation plan that will enhance a total 476.60 acres of wetlands by re-establishing a native shrub and bottomland emergent wetland community. The mitigation plan will involve removing harmful and non-native plants, removing the existing poplar tree plantation and creating shallow water areas and branching channels to help improve water flow, enhance habitat diversity and distribute nutrients and sediments throughout the area. The mitigation site is located southwest of the proposed facility within the same hydrologic unit of the proposed facility, four miles northeast of Clatskanie.

Q. What other water quality permits does NEXT need to have?

A. NEXT must apply for a construction stormwater discharge general permit, which regulates how NEXT manages its stormwater during construction of the facility. NEXT must also apply for an industrial stormwater discharge general permit, which regulates how the facility manages its stormwater while operating. Both permits are necessary before construction can begin.

Q. What happens if NEXT violates its water quality permit standards?

A. Once DEQ issues a permit for a facility, that permit is legally binding. If there is a violation of any permit condition, DEQ inspectors will use the enforcement guidance to determine the appropriate response. The response can range from a warning letter to formal enforcement, which may include corrective actions, a fine or revocation of a permit or the 401 Water Quality Certification.

Q. Why is NEXT able to continue with water quality permit and certification applications while its Land Use Compatibility Statement is under appeal with the Land Use Board of Appeals?

A. The Land Use Compatibility Statement approved by Columbia County, the local land use authority, is current and active unless the Land Use Board of Appeals invalidates the county's decision, or if the county rescinds its approval. DEQ does not have land use decision making authority.

If the Land Use Board of Appeals overturns Columbia County's land use decision, DEQ will re-evaluate any permits or certification decisions or applications. This may include rescinding previously approved permits or certifications or rejecting applications under review.


Q. Would increased fuel transport from the Port Westward dock and rail traffic increase risk of a spill into the Columbia River and nearby wetlands or agricultural land? 

A. DEQ understands the concerns local residents and workers have about the risk of a spill. NEXT is required to report spills and DEQ has emergency response equipment located nearby (at Columbia Pacific Bio-Refinery) to help mobilize a swift response. DEQ also participates in various spill drills annually to prepare for a variety of spill scenarios, including a drill exercise in August 2024 for a spill scenario in the Port Westward area.

DEQ does not have the authority to force a property owner to move its current or proposed facility, nor does DEQ have land use decision making authority. NEXT is required to have an active and approved Land Use Compatibility Statement by the local land use agency, which is Columbia County, to move forward with its construction project and apply for DEQ permits (which are also needed for construction to occur).

Columbia County approved NEXT's Land Use Compatibility Statement, which determined that the proposed NEXT facility and operations are in line with local land use requirements. If Columbia County rescinds its land use decision or the Land Use Board of Appeals overturns the county's land use decision, DEQ will re-evaluate any permits or certification decisions or applications. This may include rescinding previously approved permits or certifications or rejecting applications under review.

If a permit application submitted by NEXT meets state and federal regulatory requirements, and if NEXT continues to have an approved Land Use Compatibility Statement by Columbia County, DEQ must issue the permit.

Q. Will DEQ require an emergency spills response plan?

A. DEQ requires facilities that transfer oil over Oregon waterways to develop a spill contingency plan. However, renewable fuels are not considered oil under ORS 468B.300​ and therefore state regulations do not require NEXT to have a spill contingency plan. NEXT is required to report spills and DEQ has emergency response equipment located nearby (at Columbia Pacific Bio-Refinery) to help mobilize a swift response. DEQ also performs various types of spill drills annually, including a drill exercise in August 2024 for a spill scenario in the Port Westward area.

Columbia Pacific Bio-Refinery is the terminalling provider for the NEXT project. CPBR has oil spill contingency plans with EPA, U.S. Coast Guard and DEQ in the event of a spill at Port Westward. CPBR practices spill scenarios as spill drills regularly, which the latest worst case scenario spill drill was in August 2024. 


Air quality permit

DEQ issued NEXT's air quality permit on Aug. 30, 2022. This permit regulates air emissions from the renewable fuel facility. This decision followed a 60-day public comment period and public hearing.

On Nov. 6, 2022, the Land Use Board of Appeals overturned Columbia County's to expand the rail yard next to the fuel facility. On Dec. 16, 2022, NEXT submitted an updated, approved LUCS that no longer includes the rail facility. This is now the official LUCS for the air quality permit.

Other DEQ permits and certifications are required before NEXT can begin any sort of construction activities. This air quality permit is for regulating emissions from facility operations once the facility is built.

​Q. Does DEQ factor in the history of the company in its permitting decisions?

A. DEQ can evaluate the facility's history in Oregon. In this case, NEXT Renewable Fuels has no prior record in Oregon, so DEQ can only evaluate what is being proposed in the permit application. DEQ expects the company to provide truthful and accurate information for analysis. DEQ evaluates the application to determine whether the proposed facility can operate in compliance with air quality and Cleaner Air Oregon requirements that protect public health.

Q. What happens if NEXT violates its air quality permit standards?

A. Once DEQ issues a permit for a facility, that permit is legally binding. If there is a violation of any permit condition, DEQ inspectors will use the enforcement guidance to determine the appropriate response. The response can range from a warning letter to formal enforcement, which may include corrective actions and a fine.

Q. Why didn't DEQ revoke NEXT's air quality permit before the county re-approved the land use compatibility statement?

A. DEQ determined, in consultation with DOJ, that the agency's next step would have been to suspend the air quality permit and give NEXT Renewable Fuels 30 days to obtain an updated LUCS. However, NEXT had independently requested an updated LUCS from Columbia County and submitted it to DEQ on Friday, Dec. 16, 2022. DEQ determined this LUCS is adequate.

Land use decisions


DEQ does not have the authority to make land use decisions. Columbia County is the local land use authority for determining if the proposed NEXT facility and operations are in line with local land use requirements.

On Nov. 6, 2022, the Land Use Board of Appeals overturned Columbia County's Land Use Compatibility Statement, also referred to as a LUCS, decision to expand the rail yard next to the fuel facility. On Dec. 16, 2022, NEXT submitted an updated LUCS that no longer includes the rail facility, which was approved by Columbia County. This is now the official LUCS for NEXT's existing air quality permit and other permit applications.

On July 17, 2024, 1000 Friends of Oregon, Columbia Riverkeeper and a local farmer appealed two land use permits to the Land Use Board of appeals for a rail yard associated with the proposed NEXT facility at Port Westward.

If the Land Use Board of Appeals overturns Columbia County's LUCS decision, DEQ will re-evaluate any permits or certifications it may have issued. This may include rescinding or suspending previously approved permits or certifications or rejecting applications under review. 

Other DEQ permits are required before NEXT can begin construction activities.​
