The difference with water pollution, however, is that the problems that cause local water quality issues differ from those that create regional air pollution problems. Discharges into water are difficult to measure and effects are dependent on a variety of other factors and vary with weather and location.
Operators must use the BAT to control pollution from their industrial activities to prevent, and where that is not practicable, to reduce to acceptable levels, pollution to air, land and water from industrial activities. The Best Available Techniques also aim to balance the cost to the operator against benefits to the environment.
Load allocations provide a framework for determining the relative share of natural sources and human sources of pollution. The natural background load for a pollutant may be imprecisely understood. Industrial dischargers, farmers , land developers , municipalities , natural resource agencies, and other watershed stakeholders each have a vested ...
