TL;DR
Colorado does not issue a standalone yellow grease collector license. Renewal means keeping your Secretary of State entity, tax account, and any USDOT, CDL, scale, feed, or city credentials current. Kitchen oil is not EPA used oil. Prices come from private deals plus the USDA AMS weekly energy report, not a state quote. Confirm every fee and due date with the board that files the form. No one can promise approval times.
Do you need a license for yellow grease in Colorado?
You do not need a dedicated statewide yellow grease collector license in Colorado. There is no single card that works like an inedible kitchen grease transporter registration. You still need a legal entity, a tax account, and often motor carrier paper if the truck is heavy enough. Cities can add a business license or a wastewater rule. Confirm each item with the office that issues it.
I would not start a route on a verbal claim that yellow grease Colorado work is unregulated. That line is how people skip a city license and then lose a restaurant when an inspector asks who owns the tote.
Colorado regulates pieces of the work under different statutes. The Secretary of State files the company.[2] The Department of Revenue handles sales tax accounts.[3] CDOT and FMCSA care about the truck if you cross the commercial motor vehicle line.[4][5] CDPHE cares if you treat the oil as waste or if you process it on a site that needs solid waste or air paper.[9] CDA cares if you sell a feed fat or if you sell by weight from a commercial scale.[7][8]
That stack is the license. Renewal is keeping those pieces alive, not mailing one grease bureau a check.
If you came from yellow grease renewal in California, the contrast is sharp. California actually runs an inedible kitchen grease program. Colorado does not copy that model. Yellow grease renewal in Arizona and yellow grease renewal in Idaho are closer in spirit. You still assemble paper from general business and truck rules. Boards change forms. Read the live page.
My opinion: lock a renderer outlet and the truck rating before you buy a pallet of bins. A tote with no plant is a theft target that produces inventory you cannot legally move.
What actually gets renewed for yellow grease in Colorado?
The renewals that actually show up on a calendar are the entity periodic report, tax filings, and any motor carrier or scale credentials you hold. Colorado does not mail a yellow grease renewal invoice because it does not issue that license. Confirm current due dates with each board. Nobody here can promise processing times.
The Secretary of State requires a periodic report from reporting entities.[13] The state's business fee list has listed that report at $10, and articles of organization for a limited liability company at $50.[2] Those figures are board confirmable. If the fee page moved, trust the fee page, not a saved screenshot.
Sales tax accounts stay open with returns, even at zero, until you close them the way Revenue tells you to.[3] A USDOT number has a biennial update.[4] CDL medical cards expire on their own clock. If CDA certified a scale, that cert expires too.[7]
I treat the renderer contract as a renewal item even when it is not a state form. If the plant drops you, the oil has nowhere honest to go.
Skip paid expedite consultants for a $10 periodic report. That is a waste of money. File it yourself on the SOS system and keep the receipt in the same folder as the renderer settlements.
How much does yellow grease cost in Colorado?
There is no official Colorado yellow grease cash price. The closest public series is the USDA Agricultural Marketing Service National Weekly Ag Energy Round-Up, which posts yellow grease alongside other fats.[6] Pull the current week. Do not tattoo last summer's number on a bid sheet.
What kitchens actually receive on the Front Range is a private deal. Small independent restaurants still get a lot of free pickup. Higher volume fryer accounts sometimes get a share of a USDA linked price, minus freight and quality deducts. Nobody has a good public data set for kitchen level Colorado pay. The closest published sheet is that AMS energy report, and even that is a plant area quote, not a Denver alley quote.
Renderer settlements move with biodiesel and renewable diesel demand. Basis from a Colorado route to a plant in another state can wipe a weak week. Read the settlement line by line. Moisture, insolubles, unsaponifiables, free fatty acid. Bad oil is not the AMS headline.
If you want a feel for how other states talk about collector cost, use Yellow grease cost in Texas: what you'll actually pay and Yellow grease cost in Tennessee: what collectors actually pay as method pieces. They are not your Colorado bid.
My practice: price off the current AMS sheet, haircut for freight and FFA, and write the formula into the kitchen agreement. Handshake pennies turn into fights the first time a load gets rejected.
How long does yellow grease take in Colorado?
How long yellow grease takes in Colorado usually means one of three clocks. Standing up the paper. Getting a first pickup route tight. How long oil can sit before quality falls apart.
Paper first. An online entity filing with the Secretary of State is often quick.[2] A USDOT number through FMCSA is commonly issued in the online system without a long wait.[4] That is not an approval guarantee. It is not a grease permit. Local business licenses and any site permits for processing are the slow items. Confirm with the city clerk and with CDPHE.[9]
Route next. Once a fryer program is real, most kitchens want a weekly or every other week stop. A tote that sits a month in July is how you cook free fatty acid and eat a deduct. I would not build a 90 day hold as a business plan.
First gallon is limited by the outlet, not by a state grease desk. Get the renderer or fuel plant to say they will take your material, in writing, before you park bins. Plants reject loads. That rejection becomes your timeline.
Variable facts get confirmed with the board. No timing promises belong in a serious file.
Is yellow grease treated as used oil in Colorado?
Kitchen yellow grease is not used oil under the federal used oil rule that Colorado follows for petroleum oils. Do not build a 279 used oil program and call it your fryer route.
40 CFR 279.1 says, "Used oil means any oil that has been refined from crude oil, or any synthetic oil, that has been used and as a result of such use is contaminated by physical or chemical impurities."[1] EPA's business FAQ repeats that used oil is petroleum based or synthetic oil that has been used.[12] Fryer oil from animal or vegetable fat does not become used oil because it sat behind a restaurant.
Wrong rulebook wastes months.
If you dump oil, mix it with trap waste, or process it on a yard that looks like a solid waste operation, CDPHE solid waste rules can still apply.[9] Recycling a commodity to a renderer is a different fact pattern than running a dumpster of mixed slop. I would call CDPHE with the actual process before I leased a bay for melting.
Brown grease from an interceptor is wastewater slop. Keep it off the yellow grease ticket. That one habit saves more renderer relationships than any slogan.
Do you need a USDOT number or CDL to haul yellow grease?
You need motor carrier paper when the vehicle is a commercial motor vehicle, not because the cargo is yellow grease. A light pickup under the rating is a different stack than a tank truck.
FMCSA's definition in 49 CFR 390.5 treats a vehicle as a commercial motor vehicle in interstate commerce when it "has a gross vehicle weight rating or gross combination weight rating, or gross vehicle weight or gross combination weight, of 4,536 kg (10,001 pounds) or more, whichever is greater."[5] FMCSA also explains who must obtain a USDOT number.[4] CDOT's new carrier pages are the Colorado door for intrastate carriers who meet the state's MCS triggers.[10]
CDL rules kick in at the usual weight and combination thresholds, and for placarded hazmat. Straight used cooking oil is generally not a hazmat class. Confirm the load if you blend solvents or add chemicals I would not put on a food alley route.
I would read the GVWR off the door sticker before I argued with a port of entry. Wishful thinking does not beat the plate.
Interstate loads to a Kansas or Nebraska plant bring IFTA and IRP if you sit in that system. Still truck paper. Still not a grease card.
Does Colorado register yellow grease as commercial feed?
Colorado's commercial feed program sits at the Department of Agriculture. If you manufacture or distribute commercial feed in the state, you are in that program and you renew on CDA's cycle, not on a grease card cycle.[8] Confirm whether your exact sale is commercial feed or a raw material sale to a licensed plant. The difference matters. I would ask CDA in writing and keep the email.
21 CFR 589.2000 restricts certain mammalian protein in ruminant feed.[11] Restaurant grease can pick up plate waste. That is why serious feed fat buyers test, and why a lot of used cooking oil now goes to fuel instead. I would not promise a dairyman that alley oil is feed safe.
If you only collect and deliver to a renderer, many operators never hold a feed license. If you start advertising feed grade yellow grease from a shed, you just talked yourself into CDA's inbox.
Weights and measures applies if you sell by weight and you fall under CDA's commercial device rules.[7] A bathroom scale in the driveway is not a program. Get the device question answered before you print invoices in pounds.
What do restaurants and cities require for pickups?
Restaurants care about a clean tote, a pickup window that does not block the alley, and a contact who shows up. Cities care about FOG in the sewer. Those are not the same grease stream.
Interceptor and trap waste is brown grease. Yellow grease is fryer and grill oil that never went down the drain. Mix them and you have spoiled a load. Renderers notice. I would fire a driver who pumps a trap into a yellow tote.
Denver and other Colorado cities run FOG outreach aimed at food service. That paper is usually on the restaurant: interceptor cleaning, manifests for trap waste. Your collector file should still hold a written placement agreement for each bin, a theft process, and the renderer outlet. Stolen oil is not rare in this trade.
If you want a prebuilt packet for bin placement, theft reports, and renderer terms, YellowGreasePath sells a $149 one-time Bin + Theft + Renderer Kit. You can also write those three documents yourself and spend the money on lockable lids.
City business licenses are the renewal people forget. A home rule city can require a license to operate from an address inside town even when the state has no grease card. Check the city clerk. For how local layers stack in other states, see yellow grease renewal in Florida and yellow grease renewal in Illinois.
What should a first-year yellow grease Colorado route actually file?
Stand up the company and the tax account first.[2][3] Get an EIN from IRS if you need one. Open a bank account that is not your rent account. Talk to an insurance agent about auto liability and general liability. I will not quote a premium. Quotes go stale and they depend on radius and driving records.
Lock the outlet. Then place a few bins. Then buy only the truck you can keep full. A shiny vacuum truck in month one is a popular way to go broke.
Paper you actually use: a pickup ticket with date, location, approximate gallons or pounds, driver, and restaurant signature. Renderer bill of lading. Settlement. Photos if a bin is hit. SOS periodic report receipt.[13]
Waste of money: route software for eight stops, a vinyl wrap before the first paid load, and any consultant who offers to get you a Colorado yellow grease license that does not exist.
This guide is a reference. Call the board that files the form. Do not treat a publisher as your counsel.
How does Colorado compare with states that issue a grease card?
California is the national myth people import. It has a real inedible kitchen grease registration path. Colorado does not. Read yellow grease renewal in California so you stop filling out the wrong state's forms.
Illinois and Florida each mix state and local hauler ideas differently. Use those pages for contrast, not as copy paste attachments for a Denver account.
Colorado's gap is not freedom from law. It is fragmentation. You can be clean at the Secretary of State and still be wrong at a port of entry, or at CDA if you start selling feed fat.
I'd rather operate in a fragmented state with a clean renderer letter than hold a pretty card and have no plant. The plant is the license that keeps the oil moving.
What should you confirm with each Colorado board?
Before you spend money, ask the office that actually files the form. Fees move. Processing queues move. This table is a call list, not a permit.
| Office | Ask them | Why it matters |
|---|---|---|
| Colorado Secretary of State | Current entity fee and periodic report due date | The $50 and $10 figures live on the fee list and can change [2][13] |
| Colorado Department of Revenue | Whether these sales need a sales tax license, and what is exempt | Commodity fat sales are not something to guess [3] |
| CDOT MCS | Whether this GVWR and radius need a Colorado carrier file | Truck paper is where most new routes get surprised [10] |
| FMCSA | USDOT need and biennial update | The 10,001 lb line is federal, not a grease myth [4][5] |
| CDA Feed | Whether this distribution is commercial feed | Feed language on a website can pull you into the program [8] |
| CDA Weights and Measures | Whether this scale needs certification | Invoices in pounds without a legal device are a bad look [7] |
| CDPHE | Whether this yard is a solid waste or recycling operation | Melting and storing are not the same as a pickup route [9] |
| City clerk and wastewater | Business license and FOG rules that touch collectors | Home rule cities do their own thing |
| Your renderer | Current quality specs and reject rules | This is the outlet. Without it the rest is theater |
I would make those calls myself. A seller who handles all licenses for a Colorado grease route is often selling California folklore.
What records belong in a yellow grease renewal file?
Keep pickup tickets, bills of lading, settlements, rejected load notes, SOS filings, tax returns, insurance certificates, CDL medical cards, scale certs, and kitchen agreements. Scan them the week they happen.
How long you keep them is not a single state grease rule. Tax files often follow IRS habits, which means years, not weeks. Environmental and feed files can run longer if you are in those programs. Confirm with your accountant and with the board that regulates the activity.
When a bin is stolen, the file that matters is the placement agreement plus photos plus a police case number. Renderers and insurers do not work from a text thread.
Renewal week is a bad time to discover you never closed last year's zero sales tax returns.[3] Put a calendar reminder on the SOS periodic report the day you form the company.[13]
What mistakes wreck a Colorado collector file?
Mixing trap grease into yellow grease. Operating a 12,000 lb GVWR truck with an I'm just a pickup story.[5] Selling into ruminant feed without a real feed fat program.[11] Paying a kitchen in cash with no ticket. Skipping the city license. Melting oil on a residential lot and hoping zoning is sleepy.
Hiring someone who promises a state grease card is the other classic miss. The card does not exist. You still have a stack.
For a simple bin, theft, and renderer paperwork pack you can adapt, start at /start. YellowGreasePath publishes kits and guides. It does not file your renewals and it does not represent you at a board.
Frequently asked questions
Do you need a license for yellow grease in Colorado?
No single statewide yellow grease collector license exists. You still need an entity with the Secretary of State, usually a Revenue tax account, and truck credentials if you cross the 10,001 lb CMV line. Cities can add a business license. Confirm the stack with each board. Do not buy a consultant package that sells a grease card Colorado does not issue.
How much does yellow grease cost in Colorado?
There is no official Colorado cash quote. USDA AMS posts a National Weekly Ag Energy Round-Up that includes yellow grease. Kitchen pay is a private deal and is often zero on small accounts. Renderer netbacks move with fuel demand and quality deducts. Pull the current AMS sheet and write a formula. Do not reuse a year old Facebook number.
How long does yellow grease take in Colorado?
Entity and USDOT filings are often fast online, with no guarantee. Local licenses and any site permits are the slow pieces. Confirm with the city and CDPHE. On the route, kitchens usually need weekly or every other week service. Oil that sits through a hot month loses quality. The real limiter is a written renderer outlet, not a state grease desk.
Is a home garage tote route legal in Colorado?
Collection from restaurants can start small. Melting, storing large volumes, or running a trucking yard from a residential lot is where zoning, fire, and CDPHE questions show up. I would not process oil at a house. Ask the city planning desk and CDPHE about the actual activity before the first tote lands on a driveway.
Can you collect trap grease on the same yellow grease truck?
You can own two businesses. You should not blend the streams. Trap and interceptor waste is brown grease and a wastewater or solid waste problem. Yellow grease is fryer oil that never went down the drain. Mixed loads get rejected and can end a renderer contract. Separate tanks, separate tickets, separate stories.
Do Colorado restaurants pay you or do you pay them?
Both happen. Low volume independent kitchens still take free pickup. Higher volume fryer programs sometimes take a share of a USDA linked price after freight and FFA. Put the formula in writing. Cash with no ticket is how you create tax and theft problems you cannot unwind later.
Do you need a certified scale to sell yellow grease?
If you sell by weight and you fall under CDA commercial device rules, the scale is not optional. Confirm with CDA Weights and Measures before you print pound invoices. Selling by renderer weight on their certified scale is a common pattern for small collectors. A bathroom scale is not a program.
Does Colorado issue a renderer license for yellow grease plants?
I have not found a standalone statewide yellow grease renderer card equivalent to some ag states. A processing site still hits zoning, air, water, and possibly solid waste or feed rules. Confirm the exact activity with CDA and CDPHE. Do not assume a pickup route authorization covers a melt plant.
What if you only broker loads and never touch the oil?
Brokers still form an entity and sort tax treatment with Revenue. If you arrange motor carriage, FMCSA broker rules can apply on interstate freight. You still need a real outlet and quality specs, because a rejected load will land on someone. Confirm the broker versus carrier fact pattern before you print door magnets.
Do interstate loads out of Colorado need extra paper?
If the truck is a CMV in interstate commerce, start with a USDOT number and the usual IFTA and IRP questions. CDOT MCS is the state door for carrier credentials. The cargo being yellow grease does not create a special Colorado grease stamp. Confirm radius, GVWR, and for hire status with CDOT and FMCSA.
Is yellow grease a hazardous waste in Colorado?
Straight used cooking oil from fryers is not EPA used oil and is not typically managed as hazardous waste. Contamination, mixing with solvents, or dumping can change the analysis. Do not guess if a load is dirty. CDPHE is the office for waste characterization questions. Keep brown grease off the yellow ticket.
How often is the Colorado SOS periodic report due?
Reporting entities file a periodic report on the cycle the Secretary of State assigns to that record. The fee list has listed that report at $10. Due dates are on the SOS account, not on a grease calendar. File it on time and store the receipt with your renderer settlements. Confirm the live due date in the SOS system.
Is there sales tax on yellow grease sales in Colorado?
It depends on the buyer, the use, and how Revenue classifies the commodity. Some manufacturing inputs are exempt. Some sales are not. Do not copy a biodiesel plant's exemption onto a restaurant payment. Open the question with the Department of Revenue and keep the written answer. Guessing on tax is more expensive than a phone call.
Where do you confirm current Colorado fees and forms?
Secretary of State fee list and periodic report pages for the entity. Department of Revenue for tax accounts. CDOT MCS and FMCSA for the truck. CDA for feed and scales. CDPHE for waste or site questions. City clerk for the local business license. Fees and forms move. The live board page beats this article on any variable number.
