The civil construction of our projects is heavily regulated and we work to exceed those standards to avoid both adversely impacting neighbors by our project construction, and to prevent our electric generation facilities having drainage issues. Our projects must comply with federal, state, and local laws regarding wetlands waterways, stormwater runoff and drainage. The rainfall runoff and soil erosion from construction of the solar fields will be permitted and reviewed by state and local officials before construction. A storm water construction plan will be developed for our projects site per state and local requirements. The construction plans will include an Erosion and Sediment Control Plan (ESCP) and a Storm Water Pollution Prevention Plan (SWPPP).
Engineers evaluate the level of runoff generated during construction and whether the area of unvegetated disturbed ground would require management techniques to control erosion and transport of soils at unacceptable levels. Should soil erosion and sediment transport require mitigative measures, standard erosion and sediment control measures would be specified in the project design and implemented during construction.
During the operational life of a solar farm in Indiana, the spaces between the rows and under the solar panels will be vegetated with local pollinators. In general, the vegetation between the rows of solar panels is sufficient to slow the flow of runoff to acceptable rates such that additional control measures are not required. In the event existing drainage tiles are damaged during construction, we will immediately repair those tiles to ensure our projects improve drainage in the area.
