Four days ago, the FAA posted Zipline's Draft Environmental Assessment for five Texas metros and opened a 30-day public comment window. Residents of Houston, San Antonio, Austin, Amarillo, and El Paso can read exactly what is proposed to fly over their homes, at what altitude, how loud, and how often, and they can put objections into a record the agency is legally obligated to answer. We covered that filing yesterday.

Tracy, California is getting none of that. Amazon told the Los Angeles Times in late August that Prime Air will begin flying its MK30 drones from the East Grant Line Road fulfillment center "within a month," serving customers up to 7.5 miles out with packages up to five pounds. The company put a static MK30 on display at a downtown car show on August 29 and has published its price list: free for Prime members on orders over $50, $2.99 under that, $4.99 for non-members. What nobody in Tracy can do is read a federal environmental document about the operation, because as of the FAA's most recent update to its public drone-delivery environmental page, none exists. California's only entry remains Lockeford, from 2022. Tracy appears nowhere, in any form.

Two towns, two weeks apart, two completely different levels of public process. That is not an accident or an oversight. It is the first visible consequence of a structural change the FAA made in July, and if you operate drones commercially, manage a delivery program, or advise a city, you need to understand which lane your market is in, because the difference determines what you can read, what you can say, and when.

The July 28 fork in the road

On July 28, 2026, the FAA signed a Finding of No Significant Impact and Record of Decision on its national Programmatic Environmental Assessment for Part 135 drone package delivery, with the Notice of Availability published in the Federal Register on July 30. The mechanism, as we detailed at the time, is substitution: instead of drafting a fresh site-specific environmental assessment for every new delivery market, a process the agency says historically ran six to eight months, the FAA now measures each new Part 135 delivery application against one national study. If the proposal fits inside the programmatic envelope, including the 600-foot hub setback from noise-sensitive land uses and the 1,150 average-annual-daily-delivery cap per site, no site review gets written and no public comment window opens.

The site-specific track still exists. Chicago's draft assessment ran a comment period that closed August 14. The Zipline Texas filing posted September 11 with comments due October 11. Baton Rouge and Omaha both have draft assessments whose comment periods closed July 22, with no finals posted, and Amazon began commercial service in Baton Rouge on July 7, fifteen days before its own comment period even closed.

So which lane is Tracy in? Here is the uncomfortable answer: nobody outside Amazon and the FAA knows, and neither has said. The site may have been checked against the national PEA and cleared internally, in which case no document will ever appear. Or a site-specific review may still be in the pipeline. The public record is simply silent, and under the programmatic framework, silence is a permitted outcome. Reporting by DroneXL, which put written questions to Amazon this month including a request for Tracy-specific sound levels, notes those questions remain unanswered.

What Tracy residents get instead of a filing

They get Amazon's own numbers, which are real but selective. The company's FAA paperwork in Louisiana, filed under the old site-specific process, put the loudest moment of an MK30 delivery at 92.1 decibels measured 25 feet from the aircraft during the package-release hover, with cruise around 63.7 decibels from 200 feet. We walked through that Baton Rouge noise filing in August, and the pattern it revealed matters here: the environmental paperwork is where the real operating numbers get written down by someone other than the marketing department. Erik Robertson, Amazon's Prime Air operations lead for the West, told a Sacramento TV station that Tracy residents will hear something like a delivery truck passing. That comparison is defensible for cruise. It is not the number that describes the hover over your neighbor's driveway, and Tracy has no filing of its own to check either claim against.

To be fair to Amazon, the company does more community-facing work than most operators. The car show booth follows the same playbook as Hazel Park, Tinley Park, and Kansas City, and when Richardson, Texas residents complained about noise in January, Amazon raised departure altitudes and rerouted flights over commercial land by March without any regulator forcing it. The community engagement is real. It is also not a substitute for a public record. A booth answers a fixed list of questions and packs up at 1 p.m. An environmental assessment sits in a federal docket where a county supervisor can read it four years later. Lockeford had one, and while the document did not save that site when Amazon shut it down in April 2024, it meant the county could see what had been promised.

September 26 is the date that locks this in

The national FONSI is a final agency order under 49 U.S.C. § 46110, which gives any party with a substantial interest 60 days to petition a federal court of appeals for review. Sixty days from July 28 is September 26. The coalition most likely to file is known: sixteen state attorneys general plus Harris County, Texas told the FAA in their January comment letter that a nationwide assessment without site-specific data could not lawfully support a no-impact finding, and asked for a full environmental impact statement instead. The FAA answered the 241 comments in an appendix and kept its numbers.

If no petition lands by September 26, the two-lane structure is settled law for practical purposes, and the paperwork question for the remaining towns in Amazon's announced expansion to nearly 500 cities and towns by the end of 2026 is resolved by default in the agency's favor. Worth noting: Amazon's own newsroom list of live and upcoming markets still contains no California entry. Tracy surfaced through a newspaper interview, not a filing or a press release, which tells you how much visibility the published record currently gives you into where Prime Air is actually going next.

The operator read

I spent years on the flight-test side of getting unmanned aircraft approved to fly over people who did not ask for them, and this is the part of the Tracy story I would flag for anyone building or advising a program:

If you are a delivery operator, the programmatic lane is a genuine schedule gift, but it is conditional. The no-impact finding holds only if you implement the mitigation, including the 600-foot setback and the delivery cap. Exceed the envelope and you tier off into supplemental review, potentially a full impact statement. Build your site-selection screen around the PEA's limits now, and keep a documented conformity file for every site you stand up under it. If the finding is challenged and modified, the operators with clean site-level documentation will be the ones who keep flying while everyone else re-papers.

If you run a DFR or public-safety program, note what disappears with the comment window: your one formal chance to put airspace-integration concerns on a record the FAA must answer. A new delivery site in your jurisdiction can now appear with roughly the notice Tracy got, which is to say a car show. Get ahead of it. Track the FAA's environmental page and your regional Amazon and Wing and Zipline announcements, and open the deconfliction conversation with the operator directly, because nobody is going to convene it for you.

If you advise a city or county, the Tracy template is your preview: prices and assurances arrive from the company, and the federal filing may never come. The productive move is not outrage, it is a specific ask. Request the operator's siting analysis against the national PEA's setback and volume limits, and ask which NEPA lane the site cleared under. Those are answerable questions with documents behind them, whichever lane applies.

The FAA's own timeline says Part 108 will eventually absorb package delivery from the Part 135 framework, and the PEA is explicitly a bridge to that transition. Bridges carry a lot of traffic before they are replaced. The next 490 towns will cross this one, and most of them will get exactly the paperwork Tracy got.

We will track the September 26 petition deadline and whatever appears, or does not appear, in the FAA's docket for Tracy in the weekly UAVHQ dispatch on Substack. And if your program's expansion plan depends on the programmatic lane staying intact, the UAVHQ BVLOS Playbook includes the siting and ConOps readiness templates for building the conformity file before a court or a regulator asks for it.
