An administrative law judge (ALJ) denies an oil company's motion for partial relief from a prehearing order and objection to a sua sponte discovery order in a case involving the company's alleged violation of several underground storage tank regulations. The prehearing order required the company and the U.S. Environmental Protection Agency (EPA) to submit prehearing exchange documents pursuant to 40 C.F.R. §22.19(a). Subsequently, each party filed its prehearing exchange.
