MITIGATION MEASURES AND REGULATORY REQUIREMENTS Geology, Topography, and Soils All earthwork and grading operations would be conducted in compliance with dust and erosion control requirements of Hawaii County Code Chapter 10, Erosion and Sedimentation Control. The proposed action includes a site -specific BMP plan developed as part of the project to minimize erosion and sedimentation during construction. The BMPs would include site -specific measures as outlined in Section 2.2 of this EA. Hydrology and Water Quality The proposed action includes site -specific BMPs to be implemented during construction in order to prevent any stormwater, sediment, soil, and debris resulting from the proposed construction from adversely impacting the coastal ecosystem or adjacent properties. Further, all earthwork grading operations would be conducted in compliance with dust and erosion control requirements of Hawaii County Code Chapter 10, Erosion and Sedimentation Control. Biological Resources During construction, site -specific BMPs developed as part of the permitting process would minimize erosion and sedimentation and potential adverse effects to aquatic biota in the vicinity of the project site. To avoid and minimize impacts to the endangered Hawaiian hoary bat, the USFWS provides the following recommendations: • Do not disturb, remove, or trim woody plants greater than 15 feet tall during the bat birthing and pup rearing season (June 1 through September 15). • Do not use barbed wire for fencing. To avoid and minimize potential project impacts to Hawaiian geese, the USFWS provides the following recommendations: • Do not approach, feed, or disturb Hawaiian geese. • If Hawaiian geese are observed loafing or foraging within the project area during the breeding season (September through April), have a biologist familiar with the nesting behavior of nene survey for nests in and around the project area prior to the resumption of any work. Repeat surveys after any subsequent delay of work of 3 or more days (during which the birds may attempt to nest). 0 Cease all work immediately and contact the USFWS for further guidance if a nest is discovered within a radius of 150 feet of proposed work, or a previously undiscovered nest is found within said radius after work begins. • In areas where Hawaiian geese are known to be present, post and implement reduced speed limits, and inform project personnel and contractors about the presence of endangered secies on -site. To avoid and minimize potential project impacts to sea turtles and their nests, the USFWS provides the following applicable recommendations: • Implement site -specific BMPs regarding sedimentation and erosion in aquatic environments identified in the project description and as recommended by the USFWS. • Have a biologist familiar with sea turtles conduct a visual survey of the project site to ensure no basking sea turtles are present. 0 If a basking sea turtle is found within the project area, cease all mechanical or construction activities within 100 feet until the animal voluntarily leaves the area. • Avoid nighttime work during the nesting and hatching season (May to December). • Minimize the use of lighting and shield all project -related lights so the light is not visible from any beach. 0 If lights can't be fully shielded or if headlights must be used, fully enclose the light source with light filtering tape or filters. To avoid and minimize potential project impacts to Hawaiian waterbirds, the USFWS provides the following recommendations, as applicable: • In areas where waterbirds are known to be present, post and implement reduced speed limits, and inform project personnel and contractors about the presence of endangered species on -site. • Implement site -specific BMPs regarding sedimentation and erosion in aquatic environments identified in the project description and as recommended by the USFWS
