Thank you, Mr. Chair.
I wanted to first express my appreciation to the commissioner. Thank you for coming. I spent a number of years on the environment committee and certainly enjoyed your candour there. I appreciate your comments today, and of course the way you keep tabs on what is happening.
I have a couple of questions for you. I'm a little confused, and perhaps you can help me understand this better. I worked in the oil field. I'm an Alberta farm boy, and of course some of us have to work off the farm, in the oil and gas sector, to support our farming habit, and I was no different.
I've worked on drilling rigs and I've worked on service rigs and so on, and I'm quite familiar with what actually happens. I've done well completions where hydraulic fracturing has actually occurred.
I looked at some of the comments you made here in the government's response to petitions, identifying some of these gaps. The points that you've raised are on identifying the substance used, assessing the risks to environmental and human health, and establishing control measures to manage the risks posed by substances determined to be toxic or capable of being toxic.
Then I went and looked for a little more information in your report. I see, for example, in exhibit 5.3, you have an oil and gas pocket typically somewhere in the neighbourhood of—well, you've actually identified it above. It says it's not to scale and typical depths are indicated. Typical well depths in western Canada at this particular point in time are well below what you show here as being the highly impermeable rock. As a matter of fact, most of the wells go through the layer of impermeable rock in order to get to the oil or gas pockets. I'm wondering if I can get some clarification on that.
Also, the Canadian Centre for Occupational Health and Safety has a list, and every oil and gas field worker that I know of has to have a transportation of dangerous goods certificate if they're involved in the transportation of these goods to and from. So every rig worker has to be completely familiar with all of the safety measures contained on a material data safety sheet. On a material data safety sheet there is the product information, such as name, manufacturer and suppliers' names; address and emergency phone numbers; the hazardous ingredients therein; the physical data; fire or explosion hazard data; the reactivity data for chemical reactions; the toxicological properties and health effects; preventative measures; first aid measures, and so on.
I'm finding it a little hard to believe that we have a gap here where I don't think one actually exists. All you have to do is simply ask what materials are being used. The material data safety sheets provide all the information, anything from toxicology right on down to human health and any of the other kinds of things that would need to be dealt with.
So I'm wondering if you can explain to me what exactly is missing here, because I'm fairly familiar with some of these chemicals and with the chemical management plan. I'm not understanding why this is receiving such criticism in your report.
