An administrative law judge (ALJ) granted in part and denied in part the U.S. Environmental Protection Agency's (EPA's) motion to strike five of six affirmative defenses and all three cross-claims raised by a county that allegedly violated the Resource Conservation and Recovery Act (RCRA) and state law. The ALJ first notes that motions to strike are generally disfavored because they are a drastic sanction and are often employed as a delay tactic.
