SULFURIC ACID SPILL REQUIRING OFFSITE NOTIFICATION
"In the owner controlled area, the plant has a tank of sulfuric acid (93% concentration, UN # 1830) for chemical control of the Circulating Water system used in the non-safety related electrical power production portion of the plant.
"At 0600 [CDT], a routine inspection of the tank found acid within the berm surrounding the tank. A leak was discovered in the berm and sulfuric acid leaked onto the surrounding area and nearby drainage ditch. The quantity of leaked acid has been estimated to be 120 gallons. The source of the leak has been determined to be a pipe on the tank and it has been isolated with a closed valve. The tank level has been stable for 4 hours. The leaked acid is contained within approximately 70 linear feet of the [limestone] ditch and has not left the site. On-site operations and chemistry personnel are neutralizing the acid with soda ash and a tanker truck was contracted to arrive on site this morning to empty the acid tank contents until a repair can be accomplished."
The leak was discovered at 0600 and isolated about 0630 CDT.
The licensee notified the NRC Resident Inspector.

TECHNICAL SUPPORT CENTER VENTILATION REMOVED FROM SERVICE FOR MAINTENANCE
"On June 20, 2013 at 1118 CDT, Byron Station removed part of the Technical Support Center (TSC) ventilation (i.e., 0VV23C) system from service to facilitate necessary maintenance on the supply fan. This work is expected to last approximately 2 hours. This maintenance affects the ability of the TSC ventilation to maintain adequate habitability during the duration of an emergency. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures. If the TSC becomes uninhabitable, the Station Emergency Director will relocate the TSC staff to an alternate TSC location in accordance with applicable procedures.
"This notification is being made in accordance with 10CFR50.72(b)(3)(xiii) due to the potential loss of an emergency response facility because of the unavailability of the ventilation system. An update will be provided once the TSC ventilation has been restored to normal operation.
"The NRC Resident Inspector has been notified [by the Licensee]."
* * * UPDATE FROM NICK CRAWFORD TO JOHN SHOEMAKER ON 6/20/13 AT 1635 EDT * * *
Maintenance has been completed and the TSC ventilation system has be restored to service.
The licensee will notify the NRC Resident Inspector.

AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE
The following was received from the State of New York via fax:
"The RSO of NYS (New York State) Licensee C2274 called to report a moisture/density (Troxler Model 4640-B 'thin layer') gauge was damaged at a worksite in Far Rockaway, NY. The source (8 mCi of 137 Cs) was in the safe position when it got damaged and the source is within the unit as determined by survey meter readings. The operator was about 5 ft. away from the gauge when it was run over by a roller. The RSO visited the site took measurements to confirm the source was still in the gauge. He called the QC Resources and took a leak test measurement. He is awaiting the results before shipping the gauge to QC Resources. A written report is forthcoming."
