The following response is intended for general information purposes only and is not to be construed as legal advice.
Unfortunately, the Driving While Impaired conviction you received in 1981 will likely show up on a background check. Though there there has been a significant period of time since the conviction, it will still be visible to the potential employer. It is likely that the employer would check either a background check or a driving record check. Both of these would likely reveal the conviction. In my experience, driving records do reveal Driving While Impaired convictions that occurred in the 1980s.
With regards to disclosing the conviction on the application, this may or may not have criminal repercussions for you. Since you are applying for a position with the federal government, please check the application thoroughly to make sure that you are not answering the questions under the penalty of perjury for nondisclosure or for answering with falsity. In my experience, especially when applying for employment with the government, it is not in your best interests not to disclose a previous conviction.
