4/9/2010	On March 29, 2010 I stopped at Behr Salvage to follow-up on stormwater control requirements per my visit on March 18th. I met with Mark Vanderveer. I found that the stormwater control issues had been properly addressed. The oil in the ditch had been cleaned up. The area and road between the inside scrap piles and perimeter fence had been graded and rocked. Silt screens were placed in front of two intakes within the salvage yard. The intakes had also been cleaned, as they were previously covered with mud. In addition a berm was constructed between the piles of scrap iron and the perimeter fence. This would likely provide a good filter, as well as a physical barrier, for petroleum contaminated stormwater emanating from the scrap piles. No further action is needed at this time.	CLAY SWANSON
3/24/2010	On March 18, 2010, I visited the Behr salvage yard and talked with Mark Wherry and Mark VanDerVeer. I observed a erosion channel at the bottom of the perimeter screen fence on the west side of the yard near the middle. About 10 feet from the fence in the ditch I also observed a tile discharge pipe. A trickle of storm water was flowing in the erosion channel and a small volume of water was discharging from the tile. The water from these sources was pooling in the adjacent ditch. There were no tile intakes in the ditch. It appeared that the ditch water would flow to the north through a heavily grassed ditch toward a creek. I noted a light sheen on the water's surface. I also notice a whitish scum on the down-wind side of the ditch water, which I believe was emulsified oil. I could not find a specific contamination source of oil. There was a large area behind the fence (east), which was extremely muddy. There were scrap piles and shredded metal piles immediately to the east of muddy area. I believe that oil accumulated from salvaging activities on the ground by the screen fence over the course of the fall and winter. When the snow melted, the water picked up the oil and began carrying it to the ditch. I asked Mr. VanDerVeer about the tile discharge. He said it came from an intake east of the fence in the muddy area. The intake led to a french drain, which, in turn, drained to the ditch. However, the drain intake was covered with mud and could not be seen.	CLAY SWANSON
3/24/2010	I advised Mr. Wherry that this was a stormwater issue and that Behr needed to soak up the petroleum in the ditch, barricade the erosion channel on the east side to minimize flow to the ditch, and to clean-up the french drain intake. He said they would do it right away and would telephone me when the remedial work was completed. Later in the day on March 18th, Mr. Wherry telephoned me and explained all remedial work had been completed. I advised him that I would do a follow-up visit and evaluate the work. I also said I would check the area from time to time to see if oil was coming off the lot during a percipitation event. Behr had a stormwater permit and P3. Records were being kept concerning inspections of the stormwater controls. I advised Mr. Wherry to incorporate this problem source, and the corrective action, to their inspection records.
