The one instrument we hold for Newfoundland and Labrador (CA-NL) has no row for sulfur dioxide. The rows below are from the place above it, which we search too.

Not held here: a discharge permit's own limits, and any rule for sulfur dioxide outside the 12 instruments we hold for this place and the places above it. A row missing here is missing from our sources, not from the law.
Free check: send your permit or your lab results, and we check each number against these rows, every verdict cited to its page, by email within 5 business days. Or send the link to a rule we do not hold: we read it and cite it by page.
