Transportation corridors such as highways, railroads, and waterways are permitted to traverse the exclusion area, provided that (1) these are not so close to the facility as to interfere with normal operation of the facility, and (2) in case of emergency, appropriate and effective arrangements are made to control traffic on the highway, railroad, or waterway in order to protect public health and safety. A reactor licensee is also required by 10 CFR 100.21(a) to designate an area immediately surrounding the exclusion area as an LPZ. The size of the LPZ must be such that the distance from the reactor to the boundary of the nearest densely populated center containing more than about 25,000 residents is at least one and one-third times the distance from the reactor to the outer boundary of the LPZ. The boundary of the population center is determined by population distribution, not political boundaries. In accordance with 10 CFR 50.34(a)(1)(ii)(D)(1), 10 CFR 52.17(a)(1)(ix)(A), and 10 CFR
