resent in elevated numbers in unheated systems as well as in cooling systems, receiving and source waterbodies, and site sewage treatment facilities. Contaminants and materials are being discovered in water that previously had not been detected or are being detected at levels that may be significantly different than expected. The proposed use of reclaimed water or from impaired water sources for station cooling raises a potential human health and ecological concern related to the release of these chemicals and materials to the environment. These chemicals or materials found in reclaimed and contaminated source water in very low concentrations that potentially could be harmful to humans and the environment. The applicant should provide the following information: • A description and the incidence of organisms of concern for public and occupational health, including enteric pathogens (e.g., Salmonella spp. and Pseudomonas aeruginosa), thermophilic fungi, bacteria (e.g., Legionella spp. and Vibrio spp.), dinoflagellates (Karenia brevis), blue- green algae, and free-living amoeba (e.g., Naegleria fowleri and Acanthamoeba spp.) during the previous ten years in the State that the site is located. • Characteristics of the site that could encourage the growth and distribution of etiological agents. • A summary of all the chemicals and materials that are known from the influent for stations using reclaimed water or impaired water for cooling. • The ER should reference information from the U.S. Centers for Disease Control and Prevention, State public health agencies, and local health agencies. 2.8.2 Noise The applicant should characterize the existing noise environment at the site. The description should include the following: • General description of the site with respect to noise (e.g., rural, industrial, etc.). • Results of any ambient noise studies that have been conducted, including the locations of noise sources and measurements, and corresponding noise
