It depends if you were actively working, or not, during the bust. If your were working, the site will usually spell out their provisional employment policies on DUI's. If you are not working, you are probably screwed. 10 CFR 26, has this little one liner, pertaining to requesting site access. It states that an individual not be granted access if they have pending drug or alcohol related charges. In other words, you have to complete all sanctions of the court, before you are eligable for hire! I know it doesn't make sense, but you can check it out! If you have a long time standing with one company, they may be able to slide you into a site or two, but since 9/11 most utilities don't want to even think about it!
One amazing thing on the DUI topic. As rediculous as it sounds, the US Constitution spells out only one substance on the planet, we have a right to, that is Alcohol! Everything else required to sustain life is purly assumed! Driving a vehicle is the problem! Operating a motor vehicle is a privilege in the US. Hopefully it is right for our troops in Iraq! I sure would hate to hear that some of our troops were casulties, because they had their driving privileges revoked!
