So roughly 24% Nitrogen, 25% Phosphorus, 4% Potassium, and 47% inert filler.
3lbs would contain .75 lbs of Phosphorus, if my math is correct.
That would violate the .5 lbs annually allowed by the new law.
Other than new lawn, repair, or one tested and found to be deficient in phosphorus is to use Starter; and the remainder is supposed to be no phosphate.
We also have application restrictions based on conditions.
Not sure how much tighter they could go.

Lake Winnipesaukee Alliance had a brochure a year or two ago advising zero phosphorous, the middle number, anywhere near the lake. That's good with me. I think 11 or 12 states have already banned it
