( CNN ) -- West Virginia has demanded a full list of any other chemicals that might have leaked from a Charleston-area storage plant after its owners revealed another compound had spilled into the Elk River . The state Department of Environmental Protection gave Freedom Industries until Wednesday afternoon to disclose `` any and all information '' related to the January 9 spill . The move came a day after the company told regulators that in addition to the methanol compound that escaped from a ruptured tank , a second chemical -- a mix of polyglycol ethers , known as PPH -- was part of the leak . PPH is not believed to pose any new health hazard for the people of Charleston , the federal Centers for Disease Control and Prevention said . But the state environmental agency said failing to accurately report the makeup of the leak is a violation of state law . `` These materials were not included in the initial information regarding the composition of the spilled materials , '' the agency stated in a Wednesday order to Freedom . In a statement issued along with the order , DEP chief Randy Huffman called the late disclosure `` completely unacceptable . '' More than 7,000 gallons of 4-methylcyclohexane methanol , known as MCHM , leaked into Charleston 's water supply after it leaked out of a Freedom Industries storage tank . The result was a do-not-use order that left about 300,000 people in the area unable to drink or bathe in their water , some for more than a week . The CDC said little is known about the health hazards of PPH , but it appears to be less toxic than MCHM and made up about 5 % of the total volume of the leaking tank . `` Given the small percentage of PPH in the tank and information suggesting similar water solubility as MCHM , it is likely that any amount of PPH currently in the water system would be extremely low , '' it said . `` However , the water system has not been tested for this material . '' Faced with numerous lawsuits as a result of the spill , Freedom Industries filed for bankruptcy protection last week . The company had no immediate response to Wednesday 's demand from state officials , who have pledged to step up their oversight of the industry .
The second chemical is n't believed to pose new health risks , the CDC says . Comment: A state official called the late disclosure `` completely unacceptable '' The January 9 leak prompted a do-not-use order for up to 300,000 people .
