On this project, at every level — federal, state, county, city — government had a choice. At every decision point, government chose the polluter. At the one decision point that would have produced the science required to make the choice unnecessary, the administration killed the program. What follows is the record: seven decisions, each one documented in the public file, each one traceable to a named agency, a named official, and a verifiable source.
Each entry below names the agency or entity responsible, describes the decision that was made, and ends with a source line a reader can verify independently. None of the facts on this page are contested. The pattern they form is the argument.
The U.S. Environmental Protection Agency negotiated with the semiconductor industry over roughly two decades to phase out long-chain per- and polyfluoroalkyl substances — PFOA, PFOS, and related compounds. The industry complied. It substituted short-chain PFAS (PFBS, PFBA, PFHxA, and related compounds) and, subsequently, ultrashort-chain PFAS. EPA finalized the federal drinking water MCL for six PFAS compounds on April 26, 2024. Four of the six are long-chain compounds that semiconductor fabs no longer use in significant quantities.
Cornell University’s 2021 non-targeted analysis of semiconductor fab wastewater identified 133 distinct PFAS compounds. The Semiconductor Industry Association’s own 2025 anonymized member survey reported an industry-average PFAS concentration of 840 nanograms per liter in fab effluent — 210 times the federal drinking water MCL. The compounds making up that 840 ng/L are not the compounds the federal MCL regulates.
In November 2024, the National Semiconductor Technology Center (Natcast) launched PRISM — PFAS Research and Innovation for Semiconductor Manufacturing — a $35 million CHIPS Act–authorized research program structured into three task forces (Analysis, Abatement, Modeling) with 8 to 15 planned awardees. The program’s explicit purpose was to produce the independent, non-industry-funded science required to characterize semiconductor PFAS discharge and develop effective treatment at fab scale.
In April 2025, Natcast completed the research agenda and submitted the awardee-selection memo to the U.S. Department of Commerce for approval. Commerce sat on the memo for five months without processing it. On August 25, 2025, Commerce Secretary Howard Lutnick declared that Natcast had not been “created legally,” refused to disburse $7.4 billion in contracted CHIPS Act funds, and announced that NIST would take over Natcast’s functions. Natcast laid off most of its staff in September 2025. The PRISM program page was deleted from Natcast’s website.
In the period since, NIST has funded approximately $496,000 in PFAS-adjacent research across two SBIR grants — neither of which addresses semiconductor fab wastewater treatment at scale. The only federally funded effort designed to generate the independent science required to regulate semiconductor PFAS discharge no longer exists.
In 2014, the City of Boise, Idaho entered into a private canal-reuse contract with Micron Technology. The contract authorized the routing of fab wastewater into a recharge system connected to the Boise Valley aquifer. The contract was signed without public notice, without PFAS disclosure by Micron, and without any PFAS testing requirement.
The contract was discovered by Boise residents in 2019 during an unrelated records review. PFAS was subsequently detected in the surrounding groundwater system. The Northwest Neighborhood Association, led by Richard Llewellyn, Ph.D. — a computational biologist — forced public accountability on the contract and on Micron’s broader PFAS discharge practices in Boise beginning in 2019. The Boise precedent established the pattern the Clay project now repeats: municipal authorization of fab wastewater management without PFAS disclosure or testing as conditions of the agreement.
The New York State Department of Environmental Conservation published Technical & Operational Guidance Series (TOGS) 1.3.13 in February 2023, signed by Division of Water Director Carol Lamb-LaFay, P.E. TOGS 1.3.13 defines “priority facilities” for PFAS permitting under the State Pollutant Discharge Elimination System. Appendix A lists 47 industrial categories by Standard Industrial Classification (SIC) code.
SIC code 3674 — semiconductor and related device manufacturing — is not included. This is the SIC code under which Micron’s Clay facility is classified. Multiple commenters, including Sierra Club Atlantic Chapter and Clean Water Action on behalf of CHIPS Communities United and the Center for Public Environmental Oversight, formally requested during the Oak Orchard public comment period that DEC add SIC 3674 to Appendix A. DEC’s response in the Responsiveness Summary: “No changes have been made to the permit in response to this comment.”
On April 10, 2026, DEC issued SPDES permit NY0030317 authorizing the discharge. Of 40 PFAS compounds covered, 38 received monitoring requirements only — no numeric discharge limits. The permit requires EPA Method 1633 as the sole analytical method. Method 1633 does not detect the short-chain and ultrashort-chain compounds Cornell documented at much higher concentrations than Method 1633 measures. Requests to require the Total Oxidizable Precursor Assay and non-targeted analysis were declined.
Empire State Development, New York State’s economic development authority, negotiated a Green CHIPS performance-based incentive package of up to $5.5 billion in tax credits for the Micron Clay project. The incentives are structured under the Excelsior Jobs Program across two 10-year phases, tied to Micron meeting defined job-creation, capital-investment, and “sustainability” milestones.
One required milestone is the completion of a Green CHIPS Sustainability Plan, which includes a commitment to “sustainable wastewater management.” That phrase is not defined anywhere in the Green CHIPS statute, regulations, or published ESD guidance. ESD has not required that “sustainable wastewater management” be defined — by a numeric standard, by reference to an external framework, or by any operational criteria — before the Industrial Treatment Plant bond is authorized or the design-build contract is awarded.
The total public subsidy package for the Clay project exceeds the $5.5 billion Green CHIPS figure. Additional components, documented in the Empire Center’s February 2024 analysis, include up to $4.9 billion in sales and use tax abatements, up to $375 million in state roadway improvements, and additional discounted utility rates through the New York Power Authority’s ReCharge NY program. The federal CHIPS Incentives award, finalized December 2024, adds up to $6.165 billion in direct federal funding.
On April 10, 2026, NYSDEC issued a companion document to SPDES Permit NY0030317 titled “Justification Statement for Inconsistency with Section 7(2) of the Climate Leadership and Community Protection Act.” The document, five pages long, opens with a finding:
“NYSDEC finds that issuing permits for the Oak Orchard Project would be inconsistent with the attainment of the statewide GHG emission levels under the Climate Act because of the projected increase in GHG emissions associated with the Oak Orchard Project.” — CLCPA Section 7(2) Justification Statement, April 10, 2026, page 3
DEC then provides the legal justification for issuing the permits anyway:
“DEC determined that permitting the Oak Orchard Project is justified because it serves the Micron Semiconductor Manufacturing Project, which directly and materially serves national security interests.” — CLCPA Section 7(2) Justification Statement, April 10, 2026, page 3
The supporting footnote cites “Title XCIX, CHIPS for America, of the William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021.” New York State’s climate law, signed in 2019, has been waived — by a decision authorized through the Governor’s administration — on the grounds that a semiconductor wastewater discharge serves national defense. This justification, to our knowledge, has no prior precedent in the issuance of a state-level environmental permit in New York.
On March 3, 2026, the Onondaga County Legislature voted 15–2 to create the Oak Orchard Industrial Sewer District — the procedural step that enables the County to bond and operate the Industrial Treatment Plant for Micron’s wastewater. (This is a separate project from the $549 million municipal Oak Orchard expansion the County legislature bonded on December 29, 2025.) The Industrial Treatment Plant itself is estimated by Brown and Caldwell, the County’s engineer, at $1.4–$2.6 billion. The bond authorizing its construction has not yet been voted. Micron is contractually obligated to reimburse the County, but the County bonds upfront, holds the SPDES permit for the industrial outfall, and is operationally liable under the Clean Water Act and New York State Environmental Conservation Law if the treatment plant fails to meet its discharge requirements.
Under federal pretreatment regulations at 40 C.F.R. §§ 403.3 and 403.5, a publicly-owned treatment works may only impose local pretreatment limits on industrial users to prevent “pass-through and interference” — industrial discharges that cause the POTW to violate its own permit. Because SPDES permit NY0030317 contains no numeric limits on 38 of 40 PFAS compounds, Onondaga County may lack federal authority to impose numeric pretreatment limits on Micron for those 38 compounds. The Onondaga Nation, through General Counsel Alma Lowry, Esq., raised this argument in formal comments dated December 23, 2025. DEC’s response in the Responsiveness Summary did not engage the legal authority question raised.
What that means, in operational terms: the public will pay to build a $1.4 to $2.6 billion industrial treatment plant (per Brown and Caldwell, the County’s engineer), is obligated to operate it in compliance, is liable if it fails, and may have limited federal authority to enforce pretreatment on the industrial source that generates the discharge most at issue. Micron invests $100 billion in the factory. The public builds and owns the treatment plant and assumes the risk.
The six other decisions above are accommodations made under existing information. Decision 02 is categorically different: it is a decision to prevent the information from existing in the first place. That is the structure of the pattern. It was not built by accident, and it does not resolve itself without pressure from outside of it.
The $100 billion Micron has committed to invest at Clay is real. The 9,000 direct jobs are real. The tax base is real. Nothing on this page is an argument against that investment.
What is at issue is whether any level of capital investment earns the right to discharge an industrial waste stream containing — at the industry’s own reported averages — 840 nanograms per liter of PFAS into a public drinking water watershed, without enforceable limits on the compounds of concern, with the public paying to build the treatment plant, with the public holding the liability if treatment fails, and with the public’s own climate law waived on national-security grounds.
PFOA is classified by the International Agency for Research on Cancer as a Group 1 human carcinogen — the same classification as asbestos and tobacco. It is one of only two PFAS compounds SPDES Permit NY0030317 places a numeric action level on. The existing Oak Orchard plant already exceeds the permit’s own action level for the other one, PFOS, before Micron sends a single drop of industrial wastewater.
The bond authorizing construction of the Industrial Treatment Plant has not yet been voted. The design-build contract has not been awarded. The Industrial Wastewater Discharge Permit from Onondaga County to Micron has not been written. The window to alter the terms of this project is still open. It is not open indefinitely.
Is your life worth a job?
The window is still open.
Over 1,000 Central New Yorkers and downstream neighbors have signed the petition demanding enforceable PFAS limits in Micron’s Industrial Wastewater Discharge Permit before the County Legislature authorizes the bond for the Industrial Treatment Plant. Add your name.
