Infosheet #5 - Storage of Petroleum Products
Table of Contents
IntroductionThis infosheet provides background to Worksheet #5 of the Environmental Farm Plan Workbook. It outlines options that you could adopt to address problem areas in your operation. These options are only applicable to fuel storages 5000 litres or less. In most cases you'll need more information before implementation: please refer to the resource materials listed in the infosheet, and consult OMAFRA Environmental Farm Plan (EFP) Technical Advisors. All options are classed as Actions or Compensating Factors. Actions address the areas of concern identified, and will change the EFP rating to (3) or Best (4). Compensating Factors are alternatives that will adequately address the concerns, but will not change the rating in the EFP worksheets. At the request of the Ontario Farm Environmental Coalition, consisting of Ontario Federation of Agriculture, Christian Farmers Federation of Ontario, AGCare, and the Ontario Farm Animal Council, the following people contributed to the development of Worksheet #5 and reviewed Infosheet #5: Jim Myslik, OMAFRA (Chair) Technical Editing Committee: The following people contributed to the revision (2004) of Infosheet #5: Daniel Ward, OMAFRA (Co-Chair) Technical Editing Committee: OMAFRA = Ontario Ministry of Agriculture, Food and Rural Affairs | Top of Page | Fuel StorageIssue 5-1Dispenser (hose, nozzle, pump)Proper equipment that has been designed and tested for dispensing fuel is required to meet legislation and to avoid accidental spills because of overfilling or siphoning. Small amounts of fuel in surface or ground water can cause serious harm to humans and animals, and often are not detectable by taste. Only approved dispensers (e.g., by ULC, CSA or cUL) are acceptable under the Liquid Fuels Handling Code. What can you do?Option - ActionReplace fuel dispenser (nozzle) with an approved dispenser (e.g., by ULC, CSA or cUL) with automatic shutoff or replace with an approved hand pump. Note: When the ULC, CSA, or cUL identification cannot be found on dispensers or hand pumps and these were in use prior to September 1, 1993, they can be considered acceptable if the following three conditions are met:
However, when any changes to existing equipment are to be made, they must be with approved equipment. The three-point inspection listed above and the commitment to replacement are an acceptable compensating factor for this question. After September 1, 1993, the Gasoline Handling Code & the Liquid Fuels Handling Code requires approved equipment (e.g., ULC, CSA, or cUL clearly identified) to be used in all new installations or replacement of existing equipment.

| Top of Page | Issue: 5-2 Distance from petroleum storage to nearest surface waterHow much is surface water at risk if a spill or leak develops in a fuel storage, taking into account the soil characteristics and the distance to the surface water? Legal implications apply, primarily after there is a spill that reaches surface water and causes damage. What can you do?Option #1 - ActionMove fuel storage an adequate distance away from surface water:
Option #2 - Action(This option is only available to fuel storage tanks installed prior to September 1, 1993.) Where conditions make it very difficult to meet the minimum distance requirements, move fuel storage as far as possible from surface water and install a dike to contain any spill that might occur. In cases where the minimum distance required by the Liquid Fuels Handling Code cannot be achieved a variance from TSSA must be obtained:
The diked area must be constructed so that:

| Top of Page | Issue: 5-3 Distance from petroleum storage to wellIt is important to determine and/or get an indication of the level of natural protection that the well location and soil type provide. Full protection is never guaranteed by distance or good soil type such as clay. Separation distance and soil type are only indicators of whether extra attention should be given to maintenance, management or water testing. The greater the separation distance, the greater the opportunity for the soil to filter the water before it reaches a well. The finer the texture of the soil, the slower the water moves through the soil, allowing more opportunity for filtering. There are legal implications. Minimum separation distances between fuel storage and the well are stated in the Liquid Fuels Handling Code and the Ontario Water Resources Act. Adherence to the legislation should have occurred at the time of well construction or fuel storage installation. What can you do?Option #1 - ActionMove fuel storage an adequate distance away from water well:
Option #2 - ActionEliminate fuel storage on the farm:
Option #3 - Compensating Factor(This option is only available to storage tanks installed prior to September 1, 1993.) Where conditions make it very difficult to meet the minimum distance requirements, move fuel storage as far as possible from the well and install a dike to contain any spill that might occur. In cases where the minimum distance required by the Liquid Fuels Handling Code cannot be achieved a variance from TSSA must be obtained:
The diked area must be constructed so that:
Note: Fuel storage installed prior to September 1, 1993 may not have to be moved if the storage is in good condition and meets the remainder of the requirements of the Liquid Fuels Handling Code. However, the EFP rating does not change unless the fuel storage is moved. It is strongly recommended that the fuel storage tanks be moved an adequate distance away from the well. Any spill from a fuel storage tank that results in damage to ground water can have serious and costly legal repercussions. In order to meet the objectives of the Environmental Farm Plan, one of the three options must be selected. For More Information:

| Top of Page | Issue: 5-5Type of tank and external protection against corrosion - aboveground tanksTo avoid a spill or leak incident, it is extremely important to have an approved tank that will resist corrosion. The Liquid Fuels Handling Code requires the corrosion protection to be maintained. The Code states the type of tanks that are acceptable. What can you do?Option #1 - ActionEvaluate condition of existing fuel storage tank and maintain the corrosion protection. This applies to all tanks regardless of when they were installed: Note: Tanks in place prior to September 1, 1993 can be considered acceptable but must be in good condition, i.e., no corrosion and designed for the purpose of fuel storage. The ULC identification is not a must for these tanks. If a commitment is made to maintain the corrosion protection, it can be accepted as a compensating factor. Any tanks replaced after this date, however, must be an approved tank (e.g., by ULC, CSA, cUL or an equivalent rating accepted by the Fuels Safety Program) - no exceptions. Option #2 - ActionUse an approved fuel storage tank with corrosion protection, i.e., painted with rust inhibitor paint approved for application on steel:

| Top of Page | Issue: 5-6 Fuel dispensing - aboveground tanksThis is a very important issue. All fuel must be pumped in such a manner as to meet legislation requirements and to avoid unwanted dispensing of fuel. Elevated storages have collapsed upon filling, refuelling or accidental hitting and have resulted in serious human injuries and environmental spills. The Liquid Fuels Handling Code states that all fuel from an aboveground tank must be pumped, and shall not be dispensed by gravity. What can you do?Option - ActionDecommission any gravity flow (elevated) storage and replace with approved ground-level storage:
For More Information:
| Top of Page | Issue: 5-7Separation distances - aboveground tanksAll farmers should ensure that their fuel storage location does not create a fire safety hazard or a fume problem in any building. All fuel storage is to be located outside of buildings, meeting minimum separation distance requirements. **Heating oil tanks are permitted inside buildings provided the separation distance to a fuel-fired appliance is met. What can you do?Option - ActionMove fuel storage to a site where all the separation distances (listed in Question 7 of Worksheet #5) are met or exceeded:
Note: The Liquid Fuels Handling Code must be adhered to for any new storage installed after September 1, 1993. Also, all fuel storage modified after September 1, 1993 by changing the location of the fuel storage, must meet the separation distance requirements listed in Question 7 of Worksheet #5. Fuel storage installed prior to this date may not have to be moved to meet the separation distance requirements listed in the worksheet, provided that all of the following conditions apply:
Remember that you take the responsibility should any damage result due to location of the storage tanks. Also, include in your future plans that when improvements are being made to the fuel storage, the distances will be met. This commitment is an acceptable compensating factor. **Note: For indoor heating oil tanks, clause 6.4.7 of CSA Standard B139 states: "a tank shall be located so that… (b) the horizontal distance from the tank to any fuel-fired appliance, other than a combustible fuel-oil-driven internal combustion engine, shall not be less than 1.5m( 5ft), except when approved as part of an appliance…" If two or more fuel tanks are placed within a dike, the separation distance between the tanks need only be separated enough to allow for visual inspection and maintenance.

| Top of Page | Issue: 5-8Protection against spills/leaks - aboveground tanksA spill or leak can occur in large quantities through tank rupture, or in small quantities due to pinhole leaks. If not contained there can be serious consequences to both surface and groundwater. A dike can capture any spills or leaks from aboveground tanks. Storage tanks less than or equal to 5,000 litres are not required to be diked provided that in the event of a loss or escape, the product does not:
A judgement by the fuel tank owner or fuel user must be made as to whether the above conditions are met. It is advisable to have diking for the protection of the environment, for human safety, to avoid costly cleanups and to offset the monitoring that is required if containment is not provided. The Liquid Fuels Handling Code requires all aboveground storage tanks with a capacity of greater than 5,000 litres to be equipped with a dike. What can you do?Option #1 - ActionInstall a dike to contain spills or leaks where it is required:
Option #2 - ActionIf a dike is not required, for maximum protection install a dike to contain leaks and spills:
Option #3 - ActionIf a dike is not required, install a spill containment area under the fuel storage tank(s) for leak detection and containment of small spills:

| Top of Page | Issue: 5-9Monitoring - dike conforming to code is in place (aboveground tanks)The Liquid Fuels Handling Code requires all farmers to check their fuel storage on a regular basis to be able to prevent and identify any leaks. Some records of inspection should be kept for the life of the tank. What can you do?Option - ActionDo a visual inspection of the tank and dike for leaks and corrosion at least once per week. If a leak in the tank is detected, immediate action must be taken to prevent further loss of product. The fuel supplier should be contacted and the storage tank must be repaired or replaced. The farmer is also responsible to clear the dike of any water and deal with any contaminants as indicated in #5-8 of this infosheet. Keep some record that inspection was completed:

| Top of Page | Issue: 5-10 Monitoring - no dikes conforming to the code in place (aboveground tanks)All farmers must check their fuel storage on a regular basis to be able to prevent and identify any leaks. Some form of records listing results of inspection should be kept for the life of the tank. (i.e. Field Pocket Guide, OMAFRA Publication #820). Note: Option #1 refers to a spill containment area. A minimum containment area is a concrete pad with a continuous two-inch (five-centimetre) lip around the perimeter. This containment area is not to be confused with a dike. The purpose of the containment area is for easier visual identification of a leak or spill and to provide a firm support for the tank. Tanks sitting directly on the ground often settle and touch the ground. Corrosion will likely occur and leaks may go undetected. The two-inch lip provides a small amount of containment for minor spills or leaks and gives a chance to clean them up. Much greater protection is provided with a dike. What can you do?Option #1 - ActionFor tanks having a "spill containment area" - do a visual inspection of the tank and containment area for leaks and corrosion at least once per week. If a leak is detected, immediate action must be taken to prevent further loss of product. The fuel supplier should be contacted and the storage tank must be repaired or replaced. You are responsible to clear the containment area of any water and deal with any contaminants as indicated in #5-8 of this infosheet. Keep some record that inspection was completed:
Option #2 - ActionIf the fuel storage tank(s) are sitting on the ground or concrete pad without a two-inch (five-centimetre) containment lip, the monitoring by the farmer should be done as required in the Liquid Fuels Handling Code and indicated in Question 10B of Worksheet #5. Records must be kept by the farmer for the life of the tanks:
Note: Pumps that are not of a quality that can be calibrated for accuracy on a regular basis should be considered to be "not metered" and fall into the twice-per-month monitoring requirement. Most farm fuel pumps are in this category. A metered pump is one that accurately measures volumes and is calibrated on a regular basis (e.g., pumps used at a service station). For More Information:
| Top of Page | Issue: 5-11Combustible materials - aboveground tanksThe area in the near vicinity of the fuel storage and dispensers must be kept clear of combustible materials as required by the Liquid Fuels Handling Code, e.g., long grass, weeds, crops, oily rags, empty oil containers, tarps, loose lumber. Hydro poles that are in use are not intended to be included. What can you do?Option - ActionKeep the area around the fuel storage free of any flammable products:

| Top of Page | Issue: 5-12Method of refuelling vehicles and implementsEach farmer should assess their method of refuelling, location of refuelling, and the source of the fuel from a legislative and safety point of view. Refuelling from portable containers is an important issue. Only approved containers are allowed. Unapproved portable tanks must not be used. Injury and death have occurred as a result of the use of non-approved portable containers. Protect yourself! What can you do?Option #1 - ActionAlways fuel vehicles and/or tractors at a service station or the farm tank source:
Option #2 - ActionUse only approved containers, as required in the Liquid Fuels Handling Code, to transport fuel from the source tank to the field:

| Top of Page | Issue: 5-13Type of tank and external protection against corrosion - underground tanksCorrosion and leaks of underground tanks are not easily detected and special precautions are required. All underground fuel storages must be registered with the Fuels Safety Program, TSSA or be properly removed as required by the Fuels Safety Program, TSSA. What can you do?Option #1 - ActionRegister the underground tank with the Fuels Safety Program:
Option #2 - Action

| Top of Page | Issue: 5-14Unused tank - underground tanksUnused underground tanks are probably more of a risk to the environment than active tanks because they are usually forgotten about. Unused underground tanks include any tank that has not been removed. Tanks that have been crushed or filled up should be assessed as well. What can you do?Option - ActionProperly decommission site (effective January 1, 1997):

| Top of Page | Issue: 5-15Monitoring (underground tanks)All farmers should and must check their fuel storage on a regular basis to be able to prevent and identify any leaks. Underground storage tanks are more difficult to detect because they cannot be seen. Monitoring and keeping records are mandatory. If a leak is left undetected, there could be severe damage to the ground water. Human health is an issue if water wells are affected. What can you do?Option - ActionMonitor fuel tank as indicated in Best Rating (4):
