Class C environments refer to sea environments or outdoor land environments (with simple shielding
measures) near pollution sources. If a site is near a pollution source, it is at most 3.7 km away from salt
water, such as the sea and salt lakes, 3 km away from heavy pollution sources, such as smelteries, coal
mines, and thermal power plants, 2 km away from medium pollution sources, such as chemical, rubber,
and galvanization industries, and 1 km away from light pollution sources, such as packing houses,
tanneries, and boiler rooms.
