Not held here: a discharge permit's own limits, and any rule for cyanide outside the 17 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.
Every instrument we hold for British Columbia (CA-BC) and the place above it, Canada (CA): 17 instruments, for every parameter name matching “cyanide”: cyanide, cyanide a, cyanide free, zinc cyanide, cyanide total, ethyl cyanide, total cyanide, copper cyanide, methyl cyanide, silver cyanide, sodium cyanide, cianuri liberi, and 28 more (in the JSON).
