1. LPEA BAYFIELD SUBSTATION LA PLATA COUNTY LOCATION & EXTENT REVIEW March 12, 2015

2. Existing LPEA Substation

3.  Located on less than 0.20 of an acre parcel near intersection of Bayfield Parkway & CR 509.  Has been in operation since the 1950s.  Is very tight quartered, creating potentially dangerous conditions in which LPEA personnel must operate.  Insufficient area in which to construct the new upgraded substation facility.

4. Project Need  This project was initially prompted by rapid growth in the area from 2004 until 2008.  Bayfield Substation transformer reached 85% of its extended full load rating in 2013, and is currently nearing its capacity limit.  The transformer needs to be replaced with an uprated transformer in the near future.  In addition, other, significant upgrades to the entire facility are necessary to allow LPEA to continue to provide reliable electric service in the area, both now and in the future.  The new substation will supply adequate spare capacity in the area and supply redundant feed to the Ignacio 121 Circuit and the Rock Creek 131 Circuit.

6. Location of new Substation  LPEA initially explored a land exchange with neighboring property owner to rebuild close to existing site.  Have now reached agreement with Tri-State Generation & Transmission to build new facility on Tri-State’s Bayfield Substation property.  Site provides adequate space to construct much improved, up- to-date substation facility.  Will also include room to set up mobile substation within the fenced-in substation pad.  Will include new access off of Bayfield Parkway, with improved site distance over the existing facility. Access permit from Town of Bayfield has been acquired.

8. Environmental & Cultural Due Diligence  LPEA has completed the following tasks to ensure its compliance with various environmental & cultural considerations:  Performed wetland delineation; submitted to USACOE.  Performed drainage report & culvert sizing analysis.  Prepared a Storm Water Management Plan (SWMP) and will obtain a discharge permit from the State of Colorado.  Performed cultural resource inventory survey - no cultural resources found; submitted report and recommendation for clearance to SHPO. A determination of no effect has been made.

9. Environmental & Cultural Due Diligence (cont.)  LPEA has completed the following tasks to ensure its compliance with various environmental & cultural considerations:  Have obtained approval from USACOE to proceed with the project under Nationwide Permit 12 for disturbance to 0.05 acre of wetlands.  Will be purchasing.05 acre credits of wetland habitat in the Animas River Wetlands LLC mitigation bank to offset wetlands disturbed for this project.  Potential for 13 federally listed species to occur in project area was assessed. Was determined that there is no potential habitat for any of these species in project area; hence no impacts to these species were identified.

10. Proposed Bayfield Substation  Will be constructed on an approximate.36 of an acre gravel pad.  Will be enclosed within a 6’ high chain line fence, with barbed wire on the top.  Existing grade will be lowered, primarily on the east side, to provide a level pad and lessen the visual impact.  Retaining walls will be constructed on the north, east and south sides.  Will include a pre-fabricated 900 square foot building to house control and monitoring equipment.  Substation structures will be galvanized metal.  Construction is scheduled to begin in 2015 and be complete by the end of 2015 or the first half of 2016.
