Next I wrote to the Ontario Fire Marshal’s office. I have been told (though I can find no citation for this) that the location of the vent pipes need to be a certain distance away from a flammable structure, like a fence.
My email, sent Feb.27, 2019:
” I live next to a gas station that was recently renovated, with new underground gasoline storage tanks. The vents were moved from a previously troublefree location, far from my house. The vents are now 4′ from my property line, then another 24′ from my house. They are adjacent to my front door and most of the windows on my house. When there is a tanker refuelling, gas fumes are sometimes released. My yard is often filled with gasoline vapours. Depending on the wind direction my house is often infiltrated by gasoline vapours – despite all my windows and doors being closed. This is toxic and volatile. My property is on a lower elevation (approx 40″) so the vapours sink. There is nothing I can do to rid the house of gasoline vapours when there is an infiltration as opening the windows and doors would only let more vapours inside. I have made numerous reports to the TSSA and the Ministry of the Environment regarding this. The TSSA has sent an inspector who witnessed a refuelling, who had to admit there was a problem. I believe this situation is potentially extremely dangerous. Can the OFM help me or is there another enitity I should contact ? I am in London, ON.”
Their reply (March 12, 2019):
“Hello Ms. Johnson,
On behalf of the Office of the Fire Marshall and Emergency Management, I’d be pleased to respond to your question about gas stations. A shortcut to the Ontario Fire Code and a transcript of your question can be found beneath my signature. I have also included links to the various links of legislation cited in this message.
The Technical Standards and safety Authority (TSSA) regulates gas stations under Ontario Regulation 217/01, a regulation under the Technical Standards and Safety Act. 2000. The regulation adopts the Liquid Fuels Handling Code, 2017 (LFHC), which specifies the requirements for the storage, handling and dispensing of gasoline and associated products that are used as fuel in motor vehicles or motorized watercraft. All gas stations are required to comply with the LFHC. However, they are not necessarily required to comply with the Ontario Fire Code, and part 4 of division B of the Ontario Fire code specifically deals with flammable and combustable liquids. However, Part 4 does NOT apply to the storage, handling, transportation and use of flammable liquids to which the TSSA Act, 2000 apply. This is referenced under the Ontario Fire Code, clause 4.1.1.2.(2)(a). This provision outlines that TSSA is the authority having jurisdiction as it relates to gas stations. If offensive odours continue to persist, I would suggest that you re-engage with TSSA to express your concerns and/or discuss this matter with a member of your municipal government.
I have provided the coordinates for you to connect with customer service represntatives from TSSA.
regards,
Jay Current P.Eng

He attached a bunch of links, including one for the Liquid Fuel Handling Guide, which only took me to a portion of the site where I could buy my own copy ($ 135.00, remember ?) but not actually access the code.
Again – authority is deferred to the TSSA, who does not actually have any code pertaining to the distance these vents should be from a residence. The TSSA who does not take any samples to prove the vents are functioning properly or safely, the same TSSA who gave authority for the guy who approved the vent location to INSPECT his own work when an issue is reported. The same TSSA dude who told me I would be charged an hourly rate if he has to come back to my address again.
Shameful.
