Content:
eriod (days) for irrigated land using water withdrawn within 80 km (50 mi) of the plant radwaste discharge (downstream or radius) when crop production has the potential for contributing 10% or more to individual or population doses because of liquid effluents; the crop type and its use (e.g., human consumption, meat animals), total crop production (by type) within the 80-km (50-mi) distance, and the amounts consumed within an 80-km (50-mi) radius of the plant; transit time from the point at which the discharge stream enters an unrestricted area to the points of withdrawal, estimated dilution at each withdrawal point, and the bases for calculating transit times and dilution factors (from the ER) ` unusual animals, plants, agricultural practices, game harvests, or food processing operations having the potential for contributing 10% or more to either individual or population doses (examples are harvesting Asiatic clams found in the surface-water intake of a municipality, harvesting seaweed, [e.g., moss] in areas affected by liquid effluents, growing sweet potatoes in excess of any other food crop, producing most of the region’s potatoes in the general vicinity of the reactor, producing deer in a game-management area in quantities comparable to beef and pork production), and food-processing operations involving large quantities of water (e.g., the annual production and water-supply sources for breweries and bottling plants (from the ER). II. ACCEPTANCE CRITERIA Acceptance criteria for analyzing the radiological impacts of normal operations with respect to exposure pathways are based on the relevant requirements of the following: ` 10 CFR 50, Appendix I, with respect to guidelines for assessing radiological impacts from normal operations. Note: This criterion is not applicable to early site permit applications. ` 10 CFR 20.1301(d) with respect to exposure pathways. Regulatory positions and specific criteria necessary to meet the regulations identified above are as
