San Juan Public Lands Plan for the Future




San Juan Plan Revision Update

Supplement to Draft EIS for the San Juan Plan Revision Available August 26, 2011

Background:  During the public comment period for the Draft Land Management Plan and Draft Environmental Impact Statement (Draft LMP/EIS), the San Juan Public Lands Center (SJPLC) received comments suggesting that our Reasonable Foreseeable Development (RFD) scenario for oil and gas development projections in the Paradox Basin were low because we did not consider the development potential of the Gothic Shale Gas Play (GSGP), a potential new shale gas play underlying portions of Montezuma and Dolores counties and small portions of La Plata and San Miguel counties.  We also received comments on the Draft LMP/EIS suggesting that the type of air quality model we used in our analysis was inappropriate for the scale of the plan and that we had exceeded the capabilities of that particular model. 

We considered all of this information, and through further technical evaluation, we determined that, 1) the GSGP was a high potential play that should be evaluated; and 2) a more detailed air quality model and analysis was needed and should include the new development projections for the GSGP area.  We also determined that a Supplement to the Draft EIS was needed in order to incorporate this new information and analysis into the Draft LMP/EIS.

The two primary reasons for the Supplement to the Draft EIS are: 1) to update the shale gas development projections (i.e., number of wells, well pads, road miles, and acres of disturbance) and analysis of resource impacts associated with developing the GSGP area, and 2) to disclose the results from the recently completed air quality model based on the new development projections. 

The Supplement to the Draft Environmental Impact Statement (Draft EIS) for the San Juan Plan Revision will be available for review and comment on August 26, 2011. Written comments will be accepted during the 90-day comment period (Aug. 26 -­ Nov. 25, 2011).
