A federal judge has allowed one female environmental specialist’s wage disparities lawsuit to continue against the Virginia Department of Environmental Quality, while finding another female employee’s differing wage resulted from a factor other than sex.

The plaintiffs, Sheryl A. Kattan and Joy D. Abel, alleged that the Virginia Department of Environmental Protection (DEQ) violated the Equal Pay Act amendments to the Fair Labor Standards Act by paying them lower wages than comparable male employees. Kattan identified Justin Brown as a single comparator, while Abel identified Brian Wrenn, according to the opinion filed Tuesday in U.S. District Court for the Eastern District of Virginia.
