I. REVIEW PROCEDURES The reviewer’s analysis of nonradioactive effluent systems containing chemicals or biocides should be closely linked with the impact assessment review for ESRPs 5.3.2 and 5.5 to establish the waste stream characteristics that are most likely to result in environmental impacts. With this in mind, the reviewer should take the following steps: (1) Establish that the information necessary for subsequent impact analyses is available. NUREG-1555 3.6.1-4 October 1999 (2) Review each system effluent stream to determine that treatment processes, points of chemical addi- tions or alterations, flow characteristics, maximum and average concentrations of added and ambient water constituents, and point of discharge are identified. (3) Review the applicant’s calculations of concentrations in the effluent streams. (4) Consider any separate discharge system such as for sludge disposal. (5) Consider the concentrations and flow of the treated low-volume wastes (e.g., demineralizer wastes or boiler blowdowns) before dilution by high-volume streams. (6) Consider any waste system not described in ESRPs 3.3.2, 3.6.2, or 3.6.3 in this section (e.g., waste treatment/disposal ponds and clarifiers). (7) Consider site-related problems concerning water quality or special plant operating conditions (e.g., low oxygen levels, high concentration of nutrients, toxic materials, and high concentration factors within the plant), paying particular attention to the treatment of biocide residues. (8) Ensure that the effluent information is adequate to serve as a basis for assessing the impacts of plant operation resulting from the expected performance of the systems. (9) In evaluating the adequacy of this material, consult the applicable standards and guides for this environmental review (see Acceptance Criteria in this ESRP). Ensure that Federal, State, regional, local, and affected Native American tribal agencies appropriate to the objectives of this environ- mental review have
