ant operation. Operational monitoring programs update estimates of various effluent treatment systems’ effectiveness and provide real time warnings of any failures in the effluent treatment systems. The reviewer should describe the operational monitoring system in terms of the NPDES permitting agency’s monitoring requirements. The reviewer should also describe the status of NPDES permit consultations and NPDES permit renewal. In evaluating these monitoring programs, the reviewer should take the following steps: (1) Consider whether sufficient and adequate data to accomplish the goals of the monitoring programs will be provided. (a) If the monitoring programs are judged to be inadequate or to include unnecessary elements, consider modifications. (b) Ensure that all such recommendations are consistent with NRC policy and requirements established by the EPA or other State agencies responsible for the NPDES permit. NUREG-1555 6.6-6 October 1999 (2) Verify that the following features are described for each of the programs: ` Each monitoring program should build upon the methodology and data of the previous program. ` If data from an earlier monitoring program or project demonstrate no significant changes in a water-quality parameter, provisions to study such parameters in successive monitoring programs should be reduced or deleted. ` The intensity of sampling required for each water-quality parameter should be commensurate with the degree of impact expected. ` Sampling equipment, pattern, frequency, duration, and number of samples should be adequate to measure water-quality parameters. ` Statistical reliability, including the mean, standard deviation, and confidence limits, should be described. ` Data quality objectives, if any, should be described. ` Quality assurance procedures should be described. IV. EVALUATION FINDINGS The reviewer should verify that sufficient information has been provided by the applicant or obtained by the reviewer to meet the relevant
