EC238 Study Guide - Final Guide: Total Maximum Daily Load, Best Available Technology, Essar Steel Algoma
Document Summary
I. e concentration of sulphur dioxide in air, concentration of dissolved oxygen. Total maximum daily load: how much pollutant can be absorbed from all possible sources without becoming polluted. Calculated as sum of allowable pollution loads coming from all identifiable point sources, nonpoint sources, and margin of safety. Never-exceed levels that are applied directly to the quantity of emissions coming from pollution sources. Specify specific technologies, techniques or practices that polluting firms are required to adopt (do not specify end emissions that must be abated) Specifies that emissions at all facilities be reduced by same percentage. Firm wide trading bubble: multiplant firm can treat emissions of facilities together when considering how to achieve total abatement target. Firms must reused total emissions by target percentage, can achieve reduction by allocating abatement activities. Specifies all firms reduce emissions by the same percentage. Goal: reduction by 1994 of sulphur dioxide by 50% relative to 1980.
