The U.S. Environmental Protection Agency has tentatively denied the waiver. Their primary concern has been the potential impact of the outfall on the surrounding marine ecosystem which includes a live coral reef complex, the Manchas Interiores and Manchas Exteriores. The Rio (River) Grande de Anasco also empties into this study area, carrying a significant load of suspended sediment and contaminants that may further stress the marine community. In order to assess adequately the relative significance of the different sources of reef stress, a program was initiated to monitor the sediment and water-quality characteristics of the Rio Grande de Anasco in addition to sampling of effluent, ocean water, and sediment in the vicinity of the outfall, as well as the coral reef. In support of this effort, in December 1990, a high-resolution sidescan-sonar and seismic-reflection survey was conducted over the area that could be affected by the sewage discharge using the research vessel JEAN A (owned and operated by the Commonwealth of Puerto Rico Department of Natural Resources) in order to provide a geologic framework, or basemap for the offshore component of this program. In this report, we present the sidescan-sonar imagery, the bathymetry of the study area, ship tracklines, sediment sample locations, grain size analyses of the sediment samples, and preliminary interpretation of the data set.
