Description
Abstract

    The Roan Rim Buffer layer represents an "Area of Concern"  along the rim of the Roan Plateau where certain restrictions apply regarding pit construction and use during oil and gas operations.  These restrictions are described in COGCC Notice to Operators (NTO) dated June 12, 2008.

    The Pit Design, Construction, and Monitoring Requirements Within 3/4 Mile of the Rim of the Roan Plateau NTO can be viewed from the COGCC home page under Policies.

Purpose

    The data set was developed to illustrate the Roan Rim Buffer "Area of Concern."

Process step 1
Process description: The location of the Roan Rim was estimated using a digital elevation model to create a single Roan Rim line feature. The Roan Rim buffer zone was generated by selecting all BLM GCDB quarter-quarter sections (QQs) and lots that intersected and occupied the area between the Roan Rim line feature and a 3/4 mile Rim buffer line feature. Additional QQ/lots were added in some narrow peninsulas to fill in isolated holes. The resulting polygon layer was dissolved and clipped along the Roan Rim.
