CX-020797: Temporary Wind Tower and Ambient Air Monitoring

This revision addresses some additional activities not addressed in the original EC. Off-road vehicles (such as gators) will be utilized on the T-roads to monitor sensors. Two species of plants will be utilized for spectral sampling and analysis. The species are tobacco and brassica and will be used in two locations. The first location is on T-3 adjacent the wind tower at approximately 43.59N -112.80W. This location will include a total of 48 plants in individual pots with 24 of each type. The second location is at the High Frequency Test Bed at approximately 43.52N -112.89W. This location will include a total of 12 plants in individual pots with 6 of each type. The pots will be placed on an elevated platform for approximately 2 weeks and require daily watering. No fencing will be required to keep animals away. Eight seismic sensors will also be used. Three of the sensors are a can-type sensor (1 1/2" x 12") and the other five are a trench type sensor (4' x 6' x 12"). These sensors will be placed in the vicinity of PBF-622. The exact placement will be determined with the assistance of biological and cultural personnel in an effort to avoid biological and cultural resources.
