43.90(m) • (m) Monitoring Requirements (1) Prior to any major site construction, a preoperational monitoring • program shall be conducted for one full year to provide complete baseline data on the site and its environs. Throughout the construction and operating phases of the project, an operational monitoring program shall be conducted to measure or evaluate compliance with applicable standards and rules; to evaluate performance of control systems and procedures; to evaluate environmental impacts of operation; and to detect potential long-term effects. (2) The licensee shall establish a detection monitoring program needed for the Agency to set the site-specific groundwater protection standards in 43.90(f). For all monitoring under this paragraph, the licensee or applicant will propose, as license conditions for Agency approval, which constituents are to be monitored on a site-specific basis. The data and information shall provide a sufficient basis to identify those hazardous constituents which require concentration limit standards and to enable the Agency to set the limits for those constituents and compliance period. They may provide [he basis for adjustments to the point of compliance. The detection monitoring program must be in place when specified by the Agency in orders or license conditions. Once groundwater protection standards have been established pursuant to paragraph 43.90(f), the licensee shall establish and implement a compliance monitoring program. In conjunction with a corrective action program, the licensee shall • establish and implement a corrective action monitoring program to demonstrate the effectiveness of the corrective actions. (n) Airborne Emission and Discharge Control Requirements. Systems shall be designed and operated so that all airborne effluent releases are as low as is reasonably achievable. The primary means of accomplishing this shall be by means of emission controls. Institutional controls, such as extending the site boundary and exclusion area, may be employed to ensure that offsite exposure limits are met, but only after all practicable measures have been taken to control emissions at the source. (1) During operations and prior to closure, radiation doses from radon emissions from surface impoundments of uranium or thorium byproduct materials must be kept as law as is reasonably achiev- able. C2) Checks shall be made and logged hourly of all parameters which determine the efficiency of emission control equipaent operation. It shall be determined whether or not conditions are within a range prescribed to ensure that the equipment is operating consistently near peak efficiency. Corrective action shall be taken when performance is outside of prescribed ranges. Effluent control devices shall be operative at all times during drying and packaging operations and whenever air is exhausting from the uranium dryer stack. Drying and packaging operations shall • 43 - 24 (April 1990)
