Consideration should also be given to the need for equipment to provide

meteorological parameters (e.g., wind speed, wind direction, humidity data, and

wind direction frequencies for heights related to the estimated heights at which

stack effluents and cooling tower moisture will be dispersed). As necessary,

installation of special equipment for stack effluent dispersal and tracking should

be considered.

Effluent Control . Generally, there will be statutory limits on facility effluents

and concentrations at the point of discharge and/or the site boundary. These

statutory requirements should be identified and their requirements implemented

in design. Consideration should also be given to concentrations at neighboring

facilities, and even to operations areas of the facility outside the building,

especially for chemical releases. The design of monitoring and control systems

that reduce effluents released to the environment to ALARA levels should

emphasize the use of features that employ the best technology economically

available at the time of design. Confinement systems should minimize the

release of radioactive and other hazardous materials in facility effluents during

normal operation and anticipated operational occurrences.

Effluent Monitoring . Design for effluent monitoring should consider the

following:

Sampling and monitoring systems provide adequate and accurate

measurements under normal operations, anticipated operational

occurrences, and accident conditions. Monitoring systems should be

calibrated at least annually according to appropriate national standards.

Exhaust outlets that may contain radioisotopes other than ambient levels

of those naturally occurring in the environment should be provided with

monitoring systems. As necessary, special equipment for stack effluent

dispersal and tracking should be considered for installation. Such

monitoring provides data useful for dispersion analysis of effluent

materials.
