**The latter of which (if it is [[Hydrotreated Vegtable Oil]] and not [[FAME Biodiesel]] (aka [[Transesterification Biodiesel]] / “conventional” [[Biodiesel]] )) would not have the [[Gel Point]] / [[Fuel Lubricity]] issues of Conventional Biodiesel, and to a lesser extent Fossil-Biodiesel Blends
**They also have an [https://www.world-kinect.com/world-fuel/aviation/jet-fuel-aviation Aviation Fuels Page] and [https://www.world-kinect.com/world-fuel/marine Maritime Fuels Page]

****Uncertain if the last one is truly available or moreso a [[Greenwashing]] bluff?
**Maritime Fuels mentioned:
***Quote: “ Alternative fuel choices for your vessels - Broadly speaking, there are three main categories of non-fossil, renewable, and zero-carbon energy sources that the marine industry is exploring: - [[Hydrogen]] and its derivatives, such as [[ammonia]] - [[Biofuels]] such as [[biodiesel]] and [[bio-LNG]] - [[Synthetic fuels]] and [[electrofuels]], such as [[e-methanol]]”

=Initial Setup Cost Rough Plan=
*This section aims to determine what the cost would be OUTSIDE of the operating costs of buying fuel/insurance/inspection etc
*This also for this study rules out the use of fuel delivery business financed-loans / “fuel farm as a service” stuff etc
==Legal Fees==
*If relevant local lawyer fees for getting all paperwork setup+kosher+maybe talking with contractors etc
==Surveying/Basic Earthworks==
*Could maybe be OSE/OBI Internal Work
*Just Leveling the Site Out, MAYBE using a [[Stone Picker]],  Rotary Cultivating+Compacting if we’re feeling fancy
==Concrete Slab + CMU Containment Wall (and Optional Building/Roof Over/Around Said Pad==
*This would be for the Secondary Containment/Tertiary Containment, depending on what tank style is used
*To an extent making it into a roofed [[Warehouse]] / [[Pole Barn]] would be nicer to prevent Sun Damage / Reduce Evaporative Losses, and TO AN EXTENT keep leaves/dust and dirt (and simply rainwater too) out of the containment
**More up front cost,  but less/no time spent cleaning leaves out of containment,  no need for/less use of [[Sump Pumps]] for rainwater removal, etc
**All in all upfront cost yes, but WAAAAAAAAAAAAAAY nicer in the end (as long as [[DFC]] / [[DFD]] is still taken into account)
==Roads+Sidewalk Into/Around Said Building==
*Ideally there would be a Perimeter [[Sidewalk]] around said containment wall+pad (as well as numerous [[Containment Wall Stairs]] (ideally one or more on each side)
*A “Parallel Loading Dock” / Road Shaped Driveway Parallel to the Tank Farm / “Hose Switchboard” Leading to Said Tanks, and/or an “A-Shaped Driveway” / “Y-Shaped Driveway” would be ideal as well
**This should also act as a temporary [[Containment Pad]] for Fuel Delivery Trucks
*A Covered Roof for Inclement Weather on this would be a nice to have,  although not as essential as over the tank farm itself.
**Ideally there is a sump for rainwater,  a slope that allows for easy drainage of said rainwater to the sump (and/or DFC in the event of spills;  [[Design for Spill Cleanup]] etc)
***If electing to use a [[Sump Pump]] for removal of rainwater,  a roof (and landscaping choices) can help reduce leaves/debris accumulation in this
****To an extent though,  Maximum Height would be a factor due to the large trucks pulling into the area
==Electrical==
*At LEAST 120v Power to the Tank Farm Switchboard Pump and/or Sump Pumps etc
*Ideally having Outlets out there for incidentals AND having an [[Engineered Ground]] with a high quality [[Grounding Post]] would be ideal for Fuel Transfer Trucks + Incidentals such as Grounding and Bonding a [[Pneumatically Driven Exhaust Fan]] etc when doing CSE Work
==Pneumatics==
*While not essential, if available a [[Compressed Air Line]] (preferably [[Dry Compressed Air]] ,  although a sloped “ [[Wet Compressed Air Line]] “ ) would be nice for incidentals such as Pneumatic Tools,  [[Diaphragm Pumps]] ,  Ventilation/CSE Gear, or even simply the tired of visiting trucks
==Fire Suppression + Fire Extinguisher Equipment==
*Might need [[Fire Monitors]] + [[Fire Hydrants]] / a [[Central Fire Suppression Foam System]] for larger tank farms
*Most likely though Rated [[Fire Extinguishers]] + Placards / No Smoking or Open Light Signs + MAYBE A [[Wheeled Fire Extinguisher]] etc may be sufficient
*Also MAYBE a Fire Alarm System
**This could PROBABLY be DIY,  but if need be Pye-Barker or some similar contractor could be used
***It’s all basically 120/240/Low Voltage work,  main issue would be getting the proper gear to install (ie what Home Depot or Menards has vs what they or a supply house has!),  and the aforementioned “insurance likes someone else’s signature” bits)
==Plumbing==
*Simple [[PVC]] or [[PEX]] based Cold Water for an [[Emergency Eyewash]] and [[Emergency Shower]] station
*Also a garden hose hookup for incidentals
**If feeling fancy having an outlet not more than 5 feet or so from each Manway on large tanks would be VERY nice to reduce long hose runs etc
***This is also much harder to add later,  but the cost of PVC etc while doing the construction/concrete and all that
**The other fancy option kind of ties in with Firefighting but using [[Chicago Hose]] / [[Fire Hydrant]] style plumbing+outlets
***Worst case scenario you neck it down+use a garden hose, but if you need TONS of water you have it
*Alternately [[Self Contained Emergency Eyewash Stations]] / [[Self Contained Emergency Showers]] DO exist,  but they have to be Op-Checked + Maintained When Expired etc more once setup than their plumbed counterparts
**Plumbed ones simply need to be run every so often (to prevent rust/dry joints/stale water etc), and ensured they don’t freeze up if outdoors in the winter etx)
*Finally a sink for handwashing/custodial use is a nice splurge as well, but not 100% needed if the garden hose outlet and/or emergency wash station are there
=Initial Rough Plan BOM=
*Earthworks+Surveying Equipment
*X Kilos of [[Hydrophobic Concrete]] preferably,  some High Preformance or even rated portland mix would PROBABLY work though
**[[Hydrophobic Concrete]] MAY mean you don’t have to deal with [[Concrete Coatings]] for sealing as it would be “intrinsically sealed”
***Paint/Epoxy Coatings are a PAIN both in cost,  maintenance (paint chipping/flaking), and also generate Micro/Nanoplastic Pollution short of SOME coatings so really should be avoided if at all possible
**[[Concrete Masonry Units]] + [[Mortar]] sufficient to make that containment wall
***or POTENTIALLY a structural wall,  although a [[Pole Barn]] if sufficiently rated may be cheaper than a fully brick walled structure

*May have to spend more money on Secondary Containment]] Capacity, depending on how that math goes
**ie if Brick Containment/Pad Area is cheap,  this may be the way to go,  if it’s expensive, the Better/Best Option may be more wise
*Ideally space them out such that workers can get all around the tank for inspection+cleaning any leaks etc
*Depending on Height,  room for Ladders,  Scissor Lifts, or Heavy Equipment etc may also be advisable

**Also if an IFR is used,  either Cable Based,  or Adjustable High/Low Leg Systems etc too
**Also at MINIMUM 2 Manways,  3-4 Preferred
**Again if splurging/doing it VERY nice,  Water and/or Air and/or Electricity (mainly water though) at at least one of these manways
**Also sufficient space such that a Manway can be easily accessed+worked on (ie not directly against a wall)
*TO AN EXTENT for larger tank farms Geotextile Barrier + Gravel Based Foundations+Containment Dykes are used

***Easy to make, but keeping them in working order gets more and more expensive
****During storms they can turn into mud pits
****Long term [[Foundation Settling]] and [[Pothole]] formation can occur
****Unlike Concrete,  cleaning is difficult.  You can pressure wash a concrete pad,  gravel can only really be raked out/added to
****Finally due to tires/boots/wind etc over time the gravel will scatter,  short of EVENTUAL (geological time scale essentially) erosion etc Concrete just ''stays put''
***The geotextile can also dry rot,  or become torn
*Finally if being ESPECIALLY proper, installing one or more [[Monitor Wells]] ,  and doing soil+water samples before construction could help show you are doing things right “ie soil was either not contaminated before, or X-contaminated,  and we kept it the same”
**Not “is that dirt oil contaminated due to crappy tank farm operation? leading to potential investigation/drama/bad pr etc

Basics

  • This page aims to outline the potential for a Tank Farm for Various Fuels at FeF

Nearest Fueling Station

  • If there is a fuel station nearby, it may not be worth the trouble!
    • Granted conversely, depending on amouts of Fuel used onsite, how far the nearest station is, and if the nearby ones don’t carry EFG , Diesel / Off-Road Diesel , or Propane etc it MAY make sense regardless

Bulk Fuel Delivery Rates

Missouri Legal Requirements

Missouri Department of Natural Resources

Missouri Department of Agriculture

  • MDOA
    • The MDOA Page Titled “Fuel Device Safety and Accuracy Program”
      • TLDR: Most likely Annual or Biannual Inspections + Proof of Insurance + Designs Shall Comply with National Fire Protection Association (NFPA) 30, 30A and NEC, 1996 Edition.
      • Also if SELLING fuel, when inspecting they also check you aren’t selling less than a gallon but charging for a gallon etc (not that would really apply to us, unless a pump gets old/uncalibrated maybe?)

Local Service Providers

Bulk Fuel Suppliers

  • For the Fuel Itself

AN Petroleum

Moffit Services

  • Moffit Services’ Main Website
  • Website had some obnoxious popups, but may be a “bigger fish” / better in that way and/or cheaper?
  • They also show they offer the following: (at least pre-asking if YOUR LOCATION can get all those options without an “out in the boonies fee” lol)
  • Also mention “ Drive your productivity with Mobil Diesel Efficient™ fuel”
    • This is essentially the same rationale behind TopTier Gasoline but for Diesel
      • MAY be a proprietary brand though, unlike TopTier which is moreso a “Qualify, Apply, and MAYBE pay a royalty” Trademark Certification type deal?

World Kinect

Environmental Services

  • For Tank Cleanings/Water Draws, Spill Response, and Cleaning Before any Confined Space Entry work by other Contractors and/or Before Road Transport for Repair/Decommissioning
  • They MIGHT be able to do “Compliance Inspections” if that is needed, AND can’t / shouldn’t be done internally
    • ie getting a piece of paper from a third party may look nicer for regulators etc than an internal “oh SURE we checked it + it’s fine!”

Specialized Tank Cleaning/Inspection/Repair/Painting etc

  • Ie not a “blind” Clean In Place Tool such as a Gamma Jet / Butterworth etc, but essentially the Industrial Equivalent of Lacroscopic Surgery
  • Also (especially smaller) Environmental Services companies may not do mechanical repairs themselves
    • They may be able to sub-contract on their own though, so this route is worth asking about as well

Potential Options

Good

Better

  • Same as good plus:
