Here's how representative government works. The government receives feedback on a topic:

“The overwhelming majority of comments [>99.9%] from the general public, including the more than 20,000 letters from the write-in campaign, did not support the continued registration of sodium cyanide predacide uses (M-44 devices)," – EPA statement

Then it does whatever the hell it wants: EPA Re-authorizes Cyanide Traps.
