Cheatham County Generation Site EIS Scoping Report
Public and Occupational Health and Safety Implement BMPs for site safety management to minimize potential risks to workers. Transportation Implement staggered work shifts, primarily during daylight hours and a flag person during the heavy commute periods to manage construction traffic flow near the Project Site(s). Noise Construction activities would primarily be limited to daytime hours and heavy equipment, machinery, and vehicles utilized at the Project Site would meet all federal, state, and local noise requirements. Air Quality and GHG Emissions Comply with local ordinances or burn permits if burning of vegetative debris is required and use BMPs such as periodic watering, covering open-body trucks, and establishing a speed limit to mitigate fugitive dust. GHG emissions would be controlled consistent with all applicable requirements. The aeroderivative CTs would also require emission monitoring and controls. TVA would achieve emissions reduction by implementation of DLE combustion systems and Selective Catalytic Reduction (SCR). Exhaust stacks would also be equipped with continuous emissions monitoring systems for carbon monoxide (CO), oxides of nitrogen (NOx) and oxygen. The frame CTs would also require emission monitoring and controls. Transmission TVA employs standard practices when constructing, operating, and maintaining transmission lines, structures, and the associated right-of-way (ROW) and access roads. Some of the more specific routine measures that would be taken to reduce the potential for adverse environmental effects during the CHG plant construction, maintenance, and operation of facilities are as follows: • To minimize the introduction and spread of invasive species in the ROW, access roads, and adjacent areas, TVA would follow standard operating procedures consistent with EO 13112 (Invasive Species) for revegetating the areas with noninvasive plant species as defined by TVA. • Streams that could be affected by the proposed construction would be protected by implementing standard BMPs as identified in TVA’s BMP manual and the Tennessee Erosion and Sediment Control Handbook. • In areas requiring chemical treatment, only USEPA-registered and TVA approved herbicides would be used in accordance with label directions designed, in part, to restrict applications near receiving waters and to prevent unacceptable aquatic impacts. • To minimize adverse impacts on natural and beneficial floodplain values, the following mitigation measures would be implemented: o BMPs would be used during construction activities; and o Construction activities would adhere to the TVA subclass review criteria for transmission line location in floodplains.
