Final grading in progress to follow the grade of the western embankment of Highway 191. Photo taken facing north at spill location. Responsible party's contractors install rolled up absorbent pads tied to twine to recover gasoline in extraction wells. Pads will be rotated every other day. Photo taken facing south, at spill location. Absorbent pads were used to skim product from the surface of the extraction wells. Pads were either expunged of gasoline and returned to the well or swapped for new absorbent rolls. Photo taken facing South, at spill location. Final grading of site completed. Extraction wells will be trimmed closer to the embankment grade so they are less visible. Responsible party's contractors will install grounding rods in the following days. Photo taken facing south, at spill location. Final grading of area south of spill. Responsible party's contractors will revegetate based on NPS approved plan.
