For each solar project that is required to work with the Environmental Monitor, the selected Contractor will conduct a minimum of two site visits – one visit prior to construction and one after construction is complete. The DOER may request additional site visits or consultations for specific projects if deemed necessary. At the initial site visit, the selected Contractor will consult with the project developer on the steps needed to comply with the following Performance Standards: (a) no removal of field soils; (b) existing leveled field areas shall be left as is without disturbance; (c) where soils need to be leveled and smoothed, such as filling potholes or leveling, this shall be done with minimal overall impact with all displaced soils returned to the areas affected; (d) ballasts, screw-type, or post driven pilings and other acceptable minimal soil impact methods that do not require footings or other permanent penetration of soils for mounting are required, unless the need for such can be demonstrated; (e) any soil penetrations that may be required for providing system foundations necessary for additional structural loading or for providing system trenching necessary for electrical routing shall be done with minimal soils disturbance, with any displaced soils to be temporary and recovered and returned after penetration and trenching work is completed
