"This memorandum describes a proposed Erosion and Sediment Control (ESC) Corrective Action Plan to reduce sediment loading associated with groundwater seeps and stormwater runoff at the Faga'alu quarry site. The Faga'alu quarry is located at the upper terminus of the main road serving the Faga'alu Village. Managing runoff from a quarry can be challenging due to constantly changing drainage patterns as different areas of the site are excavated and material stockpiles are relocated. The Faga'alu quarry is further challenged by limited space in which to operate. The quarry is wedged between the steep hillsides being excavated and the stream channel along the site's southern boundary. All the runoff from the quarry eventually enters the stream. Recent monitoring efforts by Curtis et al., (2021) have shown that in-stream turbidity levels are significantly greater below quarry discharge locations than upstream of the operation (Figure 1)"--Page 1.
