Not held here: a discharge permit's own limits, and any rule for sulfur dioxide outside the 7 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 European Union (EU): 7 instruments, for every parameter name matching “sulfur dioxide”: sulfur dioxide, 1 decene polymer with sulfur dioxide, 2 aminoethanol compound with sulphur dioxide 1 1, 2 2 oxybisethanol reaction products with ammonia morpholine derivs residues reaction products with sulfur dioxide, ethanol 2 2 oxybis reaction products with ammonia morpholine derivs residues reaction products with sulfur dioxide.
