EPA SBIR 2026 Phase I Solicitation: Complete Guide for Startups
Executive Summary
The U.S. Environmental Protection Agency (EPA) opens its 2026 Small Business Innovation Research (SBIR) Phase I solicitation on September 24, 2026. Phase I awards are firm fixed price contracts of up to $100,000 for a six month proof of concept, followed by Phase II awards of up to $400,000 over two years and an additional commercialization option of up to $100,000. Proposals must respond directly to one of EPA's eleven published 2026 topics and are submitted through FedConnect, not Grants.gov.
EPA SBIR 2026 Phase I at a Glance
Agency: U.S. Environmental Protection Agency, SBIR Program
Solicitation opens: September 24, 2026
Closing date: published in the solicitation document when it posts to FedConnect. EPA has historically allowed roughly 6 to 8 weeks between issue date and closing date, so plan for a proposal due date in November 2026 and confirm it the day the solicitation drops.
Award instrument: contract, not a grant. This is a critical distinction that changes your registration setup and your reporting obligations.
Phase I award: up to $100,000 over a six month period of performance
Phase II award: up to $400,000 over two years, available only to companies that have completed an EPA Phase I
Commercialization option: up to an additional $100,000 in Phase II for companies that secure third party investment
Submission portal: FedConnect
Topic count: 11 topics across 4 environmental focus areas
Equity given up: none. SBIR is non dilutive funding.
What Is the EPA SBIR Program?
The EPA SBIR program funds U.S. small businesses developing commercially viable technologies that solve environmental problems within EPA's mission. EPA is one of eleven federal agencies participating in the SBIR program, and it runs a single annual Phase I solicitation.
Two features make EPA different from the larger SBIR agencies such as NIH, NSF, and the Department of Defense. First, EPA awards contracts rather than grants, which means your SAM.gov registration must be configured to accept contract awards and your proposal is evaluated as an offer under federal acquisition rules. Second, EPA runs a modest budget relative to other SBIR agencies, so responsiveness to the specific published topic is decisive. A brilliant environmental technology that does not map cleanly onto one of the eleven 2026 topics will not be competitive, no matter how strong the science is.
If your technology addresses PFAS, water reuse, air monitoring, food waste, critical minerals, battery recycling, safer chemicals, or lead detection, this solicitation deserves a serious look.
2026 EPA SBIR Phase I Topics: What EPA Is Actually Looking For
EPA published eleven topics across four focus areas for the 2026 Phase I cycle. Topic areas change every year, so prior year topic language should not be reused. Below is an overview of each topic and the problem space behind it. The binding technical requirements, including any performance thresholds, exclusions, and deliverable expectations, live in the solicitation document itself, so read the topic text in full before writing.
Focus Area 1: Clean and Safe Water
Topic 1A: Monitoring Technologies for Water Reuse. Water reuse systems, whether municipal, industrial, agricultural, or onsite, need real time or near real time assurance that treated water is safe for its intended end use. EPA is looking for monitoring approaches that reduce reliance on slow offsite laboratory analysis and give operators actionable data on contaminants, pathogens, or treatment performance. Strong proposals typically address sensor durability in real matrices, calibration and drift, data integration with existing SCADA or operator workflows, and unit economics at the scale of a real reuse facility.
Topic 1B: Treatment of PFAS in Wastewater Sewage Sludge and Biosolids. PFAS accumulate in the solids stream at wastewater treatment plants, and land application of biosolids has become a major pathway for PFAS to reenter soil and groundwater. EPA wants treatment or destruction technologies that work on the sludge and biosolids matrix specifically, which is a far harder problem than treating clear water. Expect reviewers to focus on destruction efficiency, byproduct and incomplete fluorinated product formation, energy demand, and whether the approach can be retrofitted at a working treatment plant.
Topic 1C: Technologies for the Removal and/or Destruction of PFAS in Groundwater. This topic targets in situ or ex situ approaches for contaminated groundwater, including sites near airports, fire training areas, and manufacturing facilities. Competitive concepts usually show a cost or performance advantage over granular activated carbon and ion exchange, address the full range of chain lengths including short chain PFAS, and have a credible answer for what happens to the captured or concentrated PFAS. Note that EPA directs PFAS sensing concepts to Topic 2A rather than this topic.
Focus Area 2: Air Quality
Topic 2A: Sensors to Detect PFAS in Environmental Matrices. This is the detection topic, and it covers environmental matrices broadly, including water. The underlying need is field deployable, lower cost PFAS measurement that does not require shipping samples to a laboratory for liquid chromatography mass spectrometry. Reviewers will look closely at detection limits relative to current health advisory and regulatory levels, selectivity across PFAS species and against interferences, reusability, and the path toward method acceptance.
Topic 2B: Advancing Technologies to Monitor Carbon Monoxide. Carbon monoxide monitoring spans ambient air quality networks, indoor and occupational exposure, and combustion source characterization. EPA is looking for improvements in accuracy, cost, power consumption, size, or deployment density over current instrumentation. If your concept enables distributed or community scale monitoring, quantify the data quality tradeoff explicitly rather than leaving reviewers to guess.
Focus Area 3: Circular Economy and Sustainable Materials
Topic 3A: Innovative Technologies to Prevent and Recycle Food Waste. Food waste is one of the largest single streams in U.S. landfills and a significant source of methane. EPA's framing here covers both prevention, meaning technologies that keep food from becoming waste in the first place, and recycling, meaning conversion of food waste into usable products. Proposals should be specific about where in the supply chain the technology sits, what it displaces, and who pays for it.
Topic 3B: Critical Mineral Recovery from Lithium-Ion Batteries and Safe Recycling/Reuse of Batteries. This topic sits at the intersection of domestic critical mineral supply and battery end of life safety. EPA is interested in recovery of lithium, cobalt, nickel, graphite, and other critical materials, and in safer handling, sorting, discharging, and reuse pathways for spent cells and packs. Competitive proposals address recovery yield and purity, chemistry flexibility across cell types, fire and thermal runaway risk, and the economics against virgin material pricing.
Topic 3C: Technologies that Mitigate the Impacts of Critical Mineral Mining or Extract Critical Minerals from Acid Mine Drainage. Acid mine drainage is both an environmental liability and a potential feedstock, since it often carries rare earth elements and other critical minerals in solution. EPA wants technologies that either reduce the environmental footprint of critical mineral mining or turn legacy drainage into a recovery opportunity. Site access, real world water chemistry variability, and sludge management are recurring weak points in proposals here.
Focus Area 4: Safer Chemicals
Topic 4A: Rubber Anti-Degradants That Are Lower Concern for Human Health and The Environment. Antiozonants and antioxidants are essential to tire and rubber performance, but the transformation products of widely used compounds have drawn serious environmental scrutiny, most notably in connection with aquatic toxicity in stormwater runoff. EPA is looking for alternative chemistries that preserve rubber performance and service life while presenting lower hazard for people and ecosystems. Proposals need both a toxicological rationale for why the alternative is safer and real performance data against the incumbent.
Topic 4B: Improved Lead Test Kits. Field usable lead test kits remain a bottleneck for renovation, repair, and painting compliance and for consumer and community lead screening. EPA wants improvements in sensitivity, specificity, false positive and false negative rates, ease of use by non technical users, and applicability across substrates. If your kit targets EPA recognition, address the recognition performance criteria directly in the proposal.
EPA SBIR Funding Amounts and Award Structure
Phase I: Proof of Concept
Phase I provides up to $100,000 for a six month period of performance. The objective is to establish technical merit, feasibility, and commercial potential before EPA commits further federal support. Because the period of performance is only six months, the work plan has to be genuinely achievable in that window. Overscoped Phase I plans are a common reason strong technologies score poorly.
Phase II: Development and Commercialization
Phase II provides up to $400,000 over two years and is available only to companies that have received and completed an EPA Phase I award. Selection is based on results achieved in Phase I along with technical merit, commercial potential, and impact. EPA states that Phase II contracts typically start in mid October.
Commercialization Option: Matching Private Investment
EPA offers a commercialization option of up to an additional $100,000 during Phase II for companies that secure third party investment. This is effectively a non dilutive match on private capital and is one of the more underused levers in the EPA program. If you expect to raise or close a strategic partnership during your Phase II window, build that into your commercialization plan from the start.
Total Potential Non Dilutive Funding
A company that moves through the full EPA pathway can access up to $600,000 in non dilutive federal funding across Phase I, Phase II, and the commercialization option, without giving up equity, board seats, or IP ownership.
EPA SBIR 2026 Timeline and Key Dates
September 16, 2026: EPA SBIR informational webinar covering the 2026 topics and proposal requirements. The recording, slides, and a Q and A document are posted on EPA's webinar resources page.
September 24, 2026: 2026 Phase I solicitation opens on FedConnect.
Closing date: stated in the solicitation document. Historically EPA has allowed roughly 6 to 8 weeks from issue to close, which points to a November 2026 deadline. Verify the exact date and time the moment the solicitation posts, since FedConnect enforces the deadline strictly and late proposals are not evaluated.
Early December (typical): Phase I contracts typically start, per EPA.
Mid October (typical): Phase II contracts typically start, per EPA.
Work backward from registration, not from the deadline. EPA states that the required registrations can take 6 to 8 weeks. If you are not already registered in SAM.gov, FedConnect, and the SBA Company Registry, registration is your binding constraint on this cycle, not writing time.
Registration Requirements Before You Can Submit
All of the following must be complete before proposal submission. Start today if any are missing.
Employer Identification Number (EIN)
EPA requires the EIN prior to issuance of a funding award. For an organization this is the IRS Tax Identification Number.
System for Award Management (SAM.gov)
You must have an active SAM registration and maintain it with at least annual renewal. Renewal can take as long as the original registration, so check your expiration date now. Critical detail specific to EPA: because EPA SBIR awards are contracts, your SAM profile must be configured to allow the award of "contracts" or "all awards." A profile set up only for grants will block you.
Unique Entity Identifier (UEI)
DUNS numbers were retired in April 2022. Your UEI is assigned through SAM.gov and is visible in your SAM.gov profile.
FedConnect Registration
FedConnect is the portal EPA uses for proposal submission. Your company must be registered in FedConnect to submit. FedConnect support is reachable at (800) 899-6665 or support@fedconnect.net, Monday through Friday, 8:00 a.m. to 8:00 p.m. Eastern time.
SBA Company Registry
All applicants must register in the SBA Company Registry before submission and include the resulting SBC Control ID with the proposal. This is a frequent last minute scramble for first time applicants.
How EPA Evaluates Proposals
Internal and external reviewers score proposals against three criteria groups, and each group carries one third of the overall score. Commercial merit is weighted equally with technical merit, which surprises many first time applicants from research heavy backgrounds.
Technical Review (one third)
Technical approach
Company and team, technical capability
Relevancy Review (one third)
Impact and relevance to the specific topic
Commercial Review (one third)
Innovation and intellectual property
Market opportunity
Company and team, commercial capability
Commercialization approach
Proposals are ranked by score, and EPA may also apply programmatic balance, agency priorities, and available funding in the selection decision. The practical implication is that a technically excellent proposal with a thin market section is leaving a full third of the score on the table.
Human Subjects Research and EPA Phase I
Research involving human subjects may fall under 40 CFR 26 and other federal and state requirements. Research is considered to involve human subjects if it obtains information or biospecimens through intervention or interaction with human subjects, or obtains data through using, studying, analyzing, or generating identifiable private information. Survey research counts. Any time you administer a survey, questionnaire, or other data collection instrument, you are interacting with human subjects.
Unless exempt under 40 CFR 26.104, human subjects research requires review and approval by a federally approved Institutional Review Board. EPA specifically does not recommend submitting Phase I offers that require human subjects research, because IRB approval can take 6 to 12 months and the Phase I period of performance is only six months. If your concept depends on human data, restructure the Phase I scope so that the six month work plan does not sit behind an IRB approval.
Who Is Eligible for EPA SBIR
EPA follows standard SBA SBIR eligibility rules. In general terms, the applicant must be a U.S. for profit small business with 500 or fewer employees, more than 50 percent owned and controlled by U.S. citizens or permanent residents, and the work must be performed in the United States with the principal investigator primarily employed by the company at the time of award and during the project. Ownership structures involving venture capital, private equity, or hedge fund investment, multiple affiliates, or foreign parent entities require a careful eligibility review before you invest weeks in a proposal. Confirm current requirements against the SBA SBIR site and the solicitation.
Common Reasons EPA SBIR Proposals Fail
Weak topic responsiveness. The proposal describes a good technology but does not directly answer the topic as written. With a modest budget and a full third of the score tied to relevance, this is the fastest path to a low ranking.
Six month scope creep. A Phase I work plan that implicitly needs twelve months signals poor project management to reviewers.
Commercialization as an afterthought. Market size assertions without customers, pricing, channel, or a realistic competitive comparison against incumbent technologies.
Registration failure. SAM lapsed, SAM configured for grants only, no FedConnect account, or no SBC Control ID.
Submission mechanics. FedConnect deadlines are enforced to the minute, and EPA has historically required the full proposal as a single PDF. Do not test the portal for the first time on deadline day.
Ignoring the byproduct question. In the PFAS and critical minerals topics especially, reviewers want to know what happens to the contaminant or residual stream after your process runs.
Frequently Asked Questions About the EPA SBIR 2026 Phase I Solicitation
When does the EPA SBIR 2026 Phase I solicitation open?
The 2026 Phase I solicitation opens on September 24, 2026.
When is the EPA SBIR 2026 Phase I deadline?
EPA publishes the closing date in the solicitation document itself when it posts to FedConnect. EPA has historically allowed roughly 6 to 8 weeks between issue and closing, which points to a November 2026 deadline for this cycle. Confirm the exact date and time in the solicitation, because FedConnect enforces the deadline strictly.
How much funding does EPA SBIR Phase I provide?
EPA SBIR Phase I provides up to $100,000 for a six month proof of concept project.
How much is an EPA SBIR Phase II award?
Phase II provides up to $400,000 over two years, plus a commercialization option of up to an additional $100,000 for companies that secure third party investment. Total potential funding across the pathway is up to $600,000.
Is EPA SBIR a grant or a contract?
EPA SBIR awards are contracts, not grants. This matters practically, because your SAM.gov registration must permit the award of contracts or all awards, and your proposal is submitted as an offer through FedConnect rather than through Grants.gov.
Where do I submit an EPA SBIR proposal?
Proposals are submitted through the FedConnect portal using its response function. Your company must be registered in FedConnect before you can submit.
What registrations do I need before applying to EPA SBIR?
You need an EIN, an active SAM.gov registration configured for contract awards, a Unique Entity Identifier from SAM.gov, a FedConnect account, and an SBA Company Registry registration with an SBC Control ID. EPA advises that the full registration process can take 6 to 8 weeks.
How long do EPA SBIR registrations take?
EPA states the registration process may take 6 to 8 weeks. SAM.gov renewal can take as long as an initial registration, so verify your status early rather than assuming an existing registration is active.
What topics does the EPA SBIR 2026 solicitation cover?
The 2026 solicitation covers eleven topics in four areas: Clean and Safe Water, which includes monitoring for water reuse and PFAS treatment in biosolids and groundwater; Air Quality, which includes PFAS sensors and carbon monoxide monitoring; Circular Economy and Sustainable Materials, which includes food waste, critical mineral recovery from lithium-ion batteries, and critical minerals from mining and acid mine drainage; and Safer Chemicals, which includes lower concern rubber anti-degradants and improved lead test kits.
Can I apply to EPA SBIR if my technology does not fit a published topic?
No. EPA requires proposals to be responsive to the specific topics listed in the annual solicitation. Given EPA's modest program budget, topic responsiveness is one third of your total score and is not something reviewers stretch on your behalf.
How are EPA SBIR proposals scored?
Reviewers score proposals in three equally weighted groups, each worth one third: technical review covering technical approach and technical team, relevancy review covering impact and relevance to the topic, and commercial review covering innovation and intellectual property, market opportunity, commercial team, and commercialization approach. EPA may also consider programmatic balance, agency priorities, and available funding.
Can I apply directly to EPA SBIR Phase II?
No. Phase II is available only to companies that have received an EPA Phase I award, and funding decisions are based on the results achieved in Phase I along with technical merit and commercial potential.
Does EPA SBIR take equity in my company?
No. SBIR is non dilutive funding. EPA does not take equity, board seats, or ownership of your intellectual property, and SBIR data rights protections apply to data generated under the award.
Can my EPA SBIR Phase I project involve human subjects?
EPA does not recommend it. Human subjects research generally requires Institutional Review Board approval under 40 CFR 26, which can take 6 to 12 months, and that conflicts with the six month Phase I period of performance. Survey and questionnaire research counts as human subjects research.
What happens if my EPA SBIR proposal is not funded?
EPA notifies applicants through FedConnect once funding decisions are made. If your proposal is not funded, you can request feedback on it. That debrief is valuable input for the next cycle and for other agency solicitations.
Is there a webinar or recording for the 2026 EPA SBIR solicitation?
Yes. EPA held an informational webinar on September 16, 2026 covering the 2026 topics and proposal requirements. The recording, presentation slides, and a Q and A document are available on EPA's webinar resources page.
Official EPA Notice
The EPA SBIR 2026 Phase I solicitation will open in late September, 2026. Find more information on how to apply at the How to Apply Page. Please check back for updates or sign up for the EPA SBIR Listserv to receive notifications of new funding opportunities.
Next Steps for Your EPA SBIR Application
Confirm eligibility and registration status this week. Check whether your SAM.gov registration is active and whether it permits contract awards. Registration is the single most common reason companies miss a cycle.
Map your technology to a specific topic. Pick one topic and write to it. Hedging across two topics reads as a weak fit for both.
Scope a six month work plan with clear go and no go milestones. Feasibility, not full development, is the Phase I objective.
Build the commercialization case in parallel with the technical narrative. It is a full third of your score.
Read the solicitation the day it opens and lock the exact closing date and time into your calendar with a submission buffer of at least 48 hours.
