This eroded stockpile is well within the project boundaries and there is nothing leaving the project. I consider this a problem for the contractor, not for water quality compliance. By allowing this to occur, the contractor has made the eroded stockpile soil unsuitable for use in embankment fill and has to haul it offsite at their expense. This could have been avoided by berming the top of the stockpile to direct water to pipe slope drain pipe that prevents water from flowing over the side of the fill.

Classic Rill Formation
This was about a 3:1 slope that had been track walked but not hydroseeded. Rill formation began with the first rain event and progressed with subsequent rain storms over a period of two months.

Rill Pattern
I stopped on the side of Highway 89, just east of Kanab, Utah, to video this rill pattern.
