All new pressure systems where the entire piping run is underground shall have Electronic Line Leak Detection (ELLD) and existing installations shall be upgraded with ELLD by 2020Existing single walled pressure systems shall be upgraded with electronic line leak detection in accordance with Clause 7.4.3.

ELLD will alleviate many of the problems we now have with leaking sumps and entry boots since it will provide level one leak detection (0.38 L/hr) on piping and alarm regardless of the condition of the sump. For new sites, the cost of ELLD would be approximately $6,000 for three STPs. To retrofit a similar site would cost approximately $20,000 if the site already has an electronic monitoring (all double wall sites already have monitoring system).

Deadline has passed for single wall systems.

RRG reconsidered mandating ELLD for aboveground pipe since it does not work well due to thermal expansion/contraction.

4.5.1.4. For existing single-wall suction systems, a vertical check valve shall be installed immediately below the suction pump, and an inspection plug shall be installed immediately below the check valve between the check valve and the tank. Check valves shall comply with 7.5.10 and 7.5.11.

Appendix F Overfill Protection Procedure

The petroleum industry has experienced operating problems with overfill protection devices (OPD s). OPD s installed in storage tanks and designed for gravity drop applications, lack capability for pressure deliveries. In order to provide additional options in this situation, the Liquid Fuel Handling Code requires one of the following two options: An approved overfill protection device that limits tank fills to no more than 95% of tank volume or an approved overfill protection procedure that limits tank fills to no more than 95% of tank volume. It is the equipment owner s responsibility to ensure that either an overfill protection device or an overfill protection procedure is in place. The fuel distributor is responsible for verifying the equipment or procedure being used and to deliver the product in a safe manner. The following example of an overfill protection procedure was developed by an industry committee in order to prevent overfilling of the tank during pressure fill applications. The Fuels Safety Program approves this procedure. In order to ensure that the correct tank chart is being used for the tank, the following procedure shall be used to verify the accuracy of the chart at the time of the first delivery. The information obtained shall be recorded and shall be used for future deliveries.

Formerly Regulatory Bulletin GA 02/2. Percent fill updated to 95% (instead of 90%) to match clause 2.2.2.2.

Procedure to Verify Chart Accuracy Relative to the Tank

1. Start with a minimal volume in the tank (less than 20% of nominal capacity).

2. Deliver 1,000 litres of product or 20% of the nominal tank capacity, whichever is the lesser volume, into the tank. Close the flow control valve and disengage the power take-off (PTO).

3. Re-dip the tank to determine, from the dip chart, the volume of product in the tank.

4. Subtract the opening inventory from the volume of product in the tank and compare this volume to the volume delivered

as indicated by the truck meter.

5. If these amounts vary by more than 2.5%, discontinue product delivery and advise site attendant and supervisor that

the dip chart provided is not accurate. (The attendant/supervisor should arrange to have the dip chart corrected.) Otherwise, repeat the process using delivery volumes from Step 2 until 95% of the tank volume (the maximum fill level) has been reached.

When the tank chart has been verified to be a correct representation of the storage capacity of the tank, the following fill procedure may be used.

1. Ensure that the correct tank chart is being used for the tank and record for future deliveries.

2. For the first delivery, verify the accuracy of the chart relative to the tank as per the procedure above.

3. Dip tank and determine opening inventory from tank dip chart.



4. Calculate tank capacity as 90% of the nominal tank size.

5. Calculate maximum delivery volume (Ullage).

Ullage = Tank Capacity - Opening Inventory

6. Pre-set the delivery volume on the auto-stop truck meter to a quantity less than or equal to the ullage. 7. Deliver product.

8. Record the following information on the bill of lading:

a) opening dip; b) opening inventory from tank dip chart; c) tank size; d) tank capacity at 90% fill; and e) ullage.

When filling underground and aboveground storage tanks, deliveries are to be by tight fill or by submerged delivery . Where appropriate these conditions may be achieved as follows:

a) Nozzles can be equipped with a "donut" or similar device that will provide a tight seal with the fill pipe collar to reduce the driver’s exposure to benzene.

b) Where aboveground tanks are provided with only two openings, one for the pump and one for the fill, a "donut"

can not be used. The nozzle must be provided with a "stinger" or similar device to prevent splash loading. The driver may be required to use a respirator should benzene levels warrant.
