PORTLAND, Ore. -

The acting chief of the Bonneville Power Administration is pledging to fix problems in the agency's human resources department and says Bonneville will not tolerate retaliation.

Elliot Mainzer tells the Oregonian that he's "fundamentally committed" to making sure nothing similar happens again.

Two independent audits and an investigation by the Department of Energy's Office of Inspector General uncovered massive problems within Bonneville's human resources department. They ranged from a lack of knowledge and training on federal hiring procedures to intentional manipulation of job applicant rankings that discriminated against veterans and other applicants.

The agency was also accused of retaliating against whistleblowers.

Mainzer dismissed concerns from some employees and customer groups that the Energy Department is trying to rein in BPA's autonomy.
