The following paragraph is extracted from a article about occupaitonal disease among American workers.
It will be up to the federal government, through the Occupational Safety and Health Administration (or OSHA), to set permissible levels for cotton dust in the air. The agency, whose job it is to set and enforce health standards for American workers, has been promising a cotton dust standard for several years, but still hasn't come up with one. However, OSHA's research arm has recommended that a tough standard of 0.2 of a milligram of dust be accepted.
Look at the coloured part, I wonder why the author used the word "it", I think the grammar is wrong here and the word "it" should be omitted. The sentence should be like this: whose job is to set and enforce health standards……. But the text is clearly printed so I suspect maybe "it" can be there too.
So, my question is that the sentence with "it" is right or wrong?
Thanks a lot.

It's my job to take the rubbish out at night.
My job is to take ....
