I think it would be useful to understand the noise rules in Alberta. The noise rules in Alberta are governed by something called “Directive 040”, with which all oil and gas companies, in fact all utilities, need to comply. The directive states that your noise level, for the closest residence, has to be below 40 dBA. It actually doesn't matter how far the residence is. However distant the residence is, the noise level has to be below 40 dBA at nighttime. And 40 dBA is equivalent to about a refrigerator.
