Does its function violate the doctrine of the separation of powers. Why or why not?

Direction
The doctrine of separation of powers is integral to America’s system of
governance. To this end, many have pointed to the growth of the federal
bureaucracy as a direct affront to this constitutional provision, as agencies
in the bureaucracy make and execute laws, as well as issue rulings in the
same way that the three branches of government do within their respective
spheres of influence. To this end, the federal bureaucracy has been deemed
an unaccountable, fourth branch of government. With this in mind,

Next, identify the function of your chosen agency. Does it function
include executive, legislative, or judicial powers.
