California Gulch - These operable units were originally compiled by multiple contractors from various sources over the course of several years. In November 2006 with the input from EPA project managers the operable unit boundaries were adjusted using a common base, a 0.605-meter resolution satellite image from Digital Globe taken on September 22, 2003. New boundary lines were digitzed on screen at a scale of 1:1000.
2006
California Gulch - In late 2006 OU 11 was modified by combining the Irrigated Meadows study area, digitized from this common base image, and the 500-year floodplain provided by MFG, Inc. in 2004.
04/05/2007
California Gulch - In April 2007 OU 11 was expanded to incorporate additional areas of Irrigated Meadows slated for treatment. These additional areas were likewise digitized from the common base image.

Libby Asbestos - feature geometry modified to match the current geounit geometry. The area of Libby Creek was removed from OU5 and added to OU4. OU8 was extended along Highway 37 to Libby Dam. OU2 geometry was modified to incorporate areas where additional samples were taken. Area fields were recalculated.
Five Points PCE Plume - boundaries updated 11/23/2010 by U.S. EPA GIS staff with input from the site Remedial Project Manager. Boundaries were digitized from 2009 USDA NAIP 1-meter aerial photography.
Libby Asbestos - OUs for this site were were updated based on geometry edits that were made to the geounits.
Mystery Bridge - boundaries updated by U.S. EPA GIS staff based on NPL extent, which was updated based on 2009 USDA NAIP 1-meter aerial photography.
Marshall Landfill - boundaries updated by U.S. EPA GIS staff based on NPL extent, which was updated based on 2009 USDA NAIP 1-meter aerial photography.

Carpenter/Snow Creek OUs added by ESAT contractor in 6/2011. Features were created based off sketch (with geometry detail) provided by U.S. EPA Region 8 Staff. Original documentation of sketches and descriptions can be found at: EPA.
Features loaded to SDE in 6/2011.
Wasatch Chemical Co. (Lot 6) - boundaries updated by U.S. EPA GIS staff based on NPL extent, which was updated based on 2009 USDA NAIP 1-meter aerial photography.
Libby Asbestos - OUs for this site were created with the direct input of the site RPMs and are based on both geounit boundaries and ground features from the 2009 aerial photography for Troy and Libby, MT. These features reflect decisions as of 03/01/2010.
Arsenic Trioxide - boundaries updated by U.S. EPA GIS staff with input from the site Remedial Project Manager, which are identical to NPL extent.
Three operable units were added to this feature class. The new additions were OU1 of Williams Pipeline, Woodbury Chemical and Minot Landfill. OU1 of these sites have the same boundary as their respective NPL boundaries. Additions were made on September 2, 2011 into this feature class in SDE.
