Observations <br />will include but not be limited to possible releases from any pit on location as well as the <br />unintentional release of other substances such as lubricants, antifreeze, fuel etc. <br />Well Drilling De-silting Pit Release Mitigation <br />1) The soil affected by the release will be excavated (surface scraped) to a depth necessary <br />to remove residue. It is important that this activity take place as soon as possible before <br />a stormwater event flushes the residual into Piceance Creek. It is also important to <br />minimize or eliminate disturbance of vegetation in the process of completing the clean- <br />up. <br />2) Any "light" stormwater runoff that may occur prior to or during completion of clean-up <br />activity will be collected in the lined temporary sump that was dug to contain the spill. <br />This water and soil can be placed on a location where storm runoff from it will not <br />contaminate vegetation or Piceance Creek (a more secure pit on another well pad <br />location might work). <br />3) Document the clean-up completion with digital photos of the path of the release across <br />the surface and a summary of the amount of soil material relocated in addition to any <br />comments regarding the collection of storm water during the clean-up activity. <br />4) Remove the liner, backfill the temporary sump and appropriately reclaim the area. <br />Delivering a Crystal Clear Advantage. <br />www.americansoda.com <br />
