Know Which EPA Rules Apply to Your Yard.
Before the Inspector Does.

A fueling island, a used-oil tank, a wash bay, a parts washer — each one can trigger SPCC, hazardous-waste, stormwater, air or tank rules most fleets never knew applied. X3 Environmental maps your facility to the 40 CFR programs that actually apply, scores your readiness, and builds the plan and the records before anyone with a badge shows up.

The hidden exposure

Most Fleets Trip EPA Rules They Didn’t Know Applied.

DOT tells you when it’s coming. EPA and the state don’t. Cross 1,320 gallons of oil storage and you owe an SPCC plan. Generate a few drums of solvent a month and you’re a hazardous-waste generator with labels, logs and training to prove. Wash trucks outside and you may owe a stormwater permit and a pollution-prevention plan. Let a fuel-island spill reach the storm drain and you may owe a report before the day is out. None of it lives in the DOT playbook a safety manager grew up on — and every one of them carries a fine that starts in the thousands per day.

The problem isn’t the rule you know. It’s the one you didn’t know applied to your yard.

X3 Intelligence

Your Facility In. Readiness Out.

Tell X3 what’s on the yard — tanks, fueling, wash bays, parts washers, waste streams, drains — and it maps your operation to the EPA and 40 CFR programs that apply, scores your readiness across every area an inspector reviews, and ranks the gaps by risk.

Applicability

Which programs apply to this yard — and which don’t, so you stop guessing.

SPCC

Are you over the oil-storage threshold, and is the plan, containment and inspection log in place?

Hazardous waste

Generator status, accumulation time, labels, manifests, training — where would RCRA cite you?

Stormwater & tanks

Permit coverage, SWPPP, benchmark monitoring; UST release detection and AST inspections.

Air & used oil

Permit thresholds for fueling, coatings and generators; used-oil handling and records.

Priority fixes

What to close first, ranked by penalty exposure and inspection likelihood.

Stop wondering what applies. Start knowing your score.

EPA compliance areas

Every Area an Inspector Reviews. Cited to the Rule.

X3 covers the six programs that hit fleets and facilities — scores your readiness in each, cites the section it would be written up under, and flags where your state runs a stricter delegated program.

Six Programs. One Yard.

40 CFR 112

SPCC

Oil-storage thresholds, secondary containment, the plan and the inspection log.
40 CFR 262

Hazardous waste

Generator status, accumulation limits, labels, manifests and training.
40 CFR 122

Stormwater

Industrial permit coverage, the SWPPP and benchmark monitoring.
40 CFR 280

Storage tanks

UST release detection and testing; AST inspection records.
40 CFR 60 / 63

Air

Permit thresholds for fueling, coatings and generators — and the state permits on top.
40 CFR 279

Used oil & records

Used-oil handling, wash water, and the records an inspector asks for first.

Finding the Gap Is Only the Beginning.

X3 turns each gap into a documented sequence — the plan, the records, the training and the proof — so the facility is ready on the day, not the week after the notice.

01

Profile the yard

Tanks, fueling, shop, wash bay, waste streams, drains — the operations that trigger programs.

02

Map what applies

Each program mapped to your facility, with the threshold and the section — and what doesn’t apply.

03

Score & rank

The readiness score, and the gaps ordered by penalty exposure and inspection likelihood.

04

Build the documents

SPCC and SWPPP-style plans, waste determinations, labels, inspection logs and training records — generated from your profile.

05

Train & assign

Who needs RCRA or SPCC training, who owns the monthly inspection, when the next one is due — and what the shop does in the first ten minutes of a spill.

06

Report on time

Tier II applicability flagged with its March 1 deadline — you file with your SERC, LEPC and fire department.

07

Prove it

The readiness review, the specialist work products and your permits, each with its cite — the material for the binder an inspector expects.

Map. Score. Fix. Document. One continuous workflow.

Continuous readiness

Inspection-Ready Every Month. Not Just After the Notice.

Environmental compliance is a calendar: monthly containment inspections, annual training, tank testing, permit renewals, the Tier II deadline every March. X3 keeps your permit and renewal dates in your account, flags anything expiring within 60 days on your dashboard, and re-scores the facility every time you re-run the readiness check.

Detect

The obligation that slipped, the program it belongs to, the cite it would be written up under.

Assign

To the shop lead, the terminal manager or the owner — with the date.

Prove

Each closed item lands in the facility record with its log and its date.

Your terminal manager shouldn’t rediscover the SPCC plan every time someone asks. It should already be current.

Every yard, every state

Terminals, Shops, Fuel Islands and Wash Bays. Each One Profiled.

Any facility that stores fuel or chemicals, generates waste, or drains to the street has obligations — and they differ by what’s on the ground and which state it’s in. X3 profiles each site on its own, flags where a state runs a stricter delegated program than the federal baseline, and rolls every yard up into one picture.

The outcome

Walk the Inspector Through the Yard. Not Around It.

An environmental inspection at a fleet that knows its programs is a walk and a binder. At a fleet that doesn’t, it’s a notice of violation and a consultant. X3 Environmental puts your yard in the first group — the plan on file, the drums labeled, the logs current, and the record ready before anyone asks.

FAQ

Frequently Asked Questions.

What fleet owners and terminal managers ask before they put X3 over their yard.

X3 Environmental: a black tractor under a ring of cyan light on a wet black floor
What is X3 Environmental?
An AI EPA compliance manager for fleets and facilities. It maps your yard to the 40 CFR programs that apply — SPCC, hazardous waste, stormwater, storage tanks, air, used oil — scores your readiness, drafts the plans and records, and tracks your permit and renewal dates.
Which facilities does this cover?
Any facility that stores fuel or chemicals, generates waste, or has air or stormwater obligations — terminals, maintenance shops, fuel islands, truck washes and yards. Each site is profiled on its own and rolled up into one fleet view.
How does X3 know what applies?
From your facility profile — tanks, fueling, shop operations, wash bays, waste streams, drains — mapped to EPA program thresholds and the 40 CFR sections behind them. X3 tells you what applies, what doesn’t, and where to confirm with your state.
Do you file with the EPA or the state for me?
No. X3 tells you what applies, scores your readiness, drafts the plans and documents you need, and tracks the permit and renewal dates you enter — you keep the records on site and file where required. It’s guidance and preparation, not a filing service.
What if my state has stricter rules?
Many states run delegated programs on top of the federal 40 CFR baseline. X3 flags where state requirements are likely stricter and tells you to confirm the specifics with your state regulator — it’s guidance, not a substitute for your permit.
Does X3 monitor continuously?
Partly. Permits and renewals you enter are stored in your account and anything expiring within 60 days is flagged on your dashboard, and the facility is re-scored whenever you re-run the readiness check. X3 does not yet send automatic reminders or watch your yard on its own.
What happens when something slips?
The gap shows in your score with the program and the cite, X3 ranks it by penalty exposure, and the readiness review tells you the fix for each gap, with its cite.
Does it work across multiple terminals?
Yes. X3 scores at the asset, facility, terminal-network, fleet and executive level, so leadership sees which yard would fail first and where exposure is concentrated.
Does AI replace our environmental consultant?
No. X3 is decision support that makes every hour with your consultant, your state regulator or the inspector more productive. Human judgment remains essential, and final responsibility for compliance rests with the facility owner.
How does pricing work?
One plan, priced by power unit. From $99 a month, which covers your first 10 units. Units 11 through 50 add $10 each per month, and every unit past 50 adds $5, unlimited. Every facility is included at every size.
How fast can we be inspection-ready?
The readiness score and gap list are immediate. Most facilities close the paperwork gaps — SPCC plan, waste determinations, labels, training logs — in days, not months, using the documents X3 generates.
Inspection-ready, every day.
