NOTIFICATION OF OFFSITE AGENCIES DUE TO SULFURIC ACID LEAK WITHIN THE D.C. COOK PROTECTED AREA
"At 1303 EDT on March 1, 2017, DC Cook notified the State of Michigan of a sulfuric acid tank leaking over 1,000 gallons of acid into the tank's berm. The leak was identified at approximately 1000 EDT coming from a drain line flange. The berm is designed to contain over 15,000 gallons which is sufficient to collect the known capacity of the tank. Cleanup of the sulfuric acid from the berm is ongoing, with no release to the environment or nearby drains."
"This notification is being made in accordance with 10 CFR 50.72(b)(2)(xi) due to notification of offsite agencies."
"The NRC Resident Inspector was notified."
