V.NARRATIVE OF OBSERVATIONS On December 14, 2010 at about 1010 hours, DISC personnel Mr. Baillie, Mr. Hunt, Mr. Mahmood, and Ms. Tran, the Environmental Health Specialist from San Joaquin County Environmental Health arrived at PNA. DTSC staff introduced themselves to the security personnel at the entrance and requested to meet with Mr. Wang, Environmental Manager. The security personnel informed Mr. Wang. The security personnel then instructed DTSC staff to park in the designated visitor's parking area and enter the reception lobby to wait for Mr. Wang. At approximately 9:05 am, Mr. Wang arrived along with Ms. Cindy Ward, the safety specialist and introduced themselves to DTSC personnel. Ms Ward informed DTSC staff that she joined PNA about a week ago. Mr. Mahmood informed Mr. Wang that DTSC staff was there to conduct a Compliance Evaluation Inspection of hazardous waste management operations at PNA. Mr. Mahmood explained that the inspection would involve walking through the facility, getting an understanding of their glass manufacturing process and waste generation, including taking photographs, and samples, and reviewing related documents. Mr. Wang replied "sure," and then gave consent to conduct the inspection on December 14, 2010, at 0913 hours. Mr. Baillie requested that the inspection should commence at the raw material receiving area and then proceeded through the manufacturing processes. Mr. Wang agreed and then led DTSC inspectors and San Joaquin County Environmental Health inspector to the raw material section. Mr. Wang gave an overview of the facility's background and various operations such as raw materials, melting, conditioning, forming, annealing, inspection, and packaging. Mr. Wang briefly explained that the facility generally operates 24 hours per day in three shifts. Mr. Wang informed DTSC staff that PNA has one furnace. Mr. Wang informed DTSC staff that PNA had furnace cold repair in 1994 and next repair is scheduled for 2013. Mr. Baillie asked if the facility had done a waste determination on the furnace's bricks which when removed become a waste. Mr. Wang explained that the facility took great care to select bricks that were completely free of chrome so that the bricks would not be a hazardous waste once the bricks were removed. On January 11, 2011, PNA submitted analytical results for the furnace's bricks to DTSC and indicates it is non-hazardous. The inspection started at the raw material section which is situated inside the building. On our way to the raw material section, DTSC staff observed spent filter bags in a trash dumpster situated outside the building near the raw material section. DTSC staff asked PNA staff about the spent filter bags. Mr. Wang informed DTSC that those spent filter bags are from the baghouse. DTSC staff asked Mr. Wang how the spent baghouse filters are being managed by the facility. Mr. Wang informed DTSC staff that the spent baghouse filters are disposed to trash and shipped off site to the landfill as a non-hazardous waste. DTSC staff asked Mr. Wang if PNA has performed any waste characterization on the spent baghouse filters. Mr. Wang replied, "Not sure". DTSC staff informed PNA that the spent baghouse filters could be hazardous for metal content. Mr. Wang further informed DTSC that the dust generated from the raw material mixing is discharged to the baghouse and then collected in the dust collector bags. Mr. Wang explained that when the baghouse is shut down for repair or filter replacement, the baghouse dust is transferred to the cyclone separator and then collected in the dust collector bags. The baghouse is turned on after repair and the cyclone separator is shut off. PNA utilizes the baghouse most of the time. The dust from the baghouse and cyclone separator is recycled back to the furnace manually. DTSC staff also observed dust on the floor near the baghouse and cyclone separator situated outside building. DTSC staff asked Mr. 8 of 73
