The EPA has issued a new rule, which will go into effect in July 2011, requiring new sources of at least 100,000 tons of greenhouse gases per year and all existing plants that have increased emissions of 75,000 tons will have to seek permits. The permit program is intended to regulate the country’s large emitters, which the EPA estimates account for 70% of the country’s greenhouse gas emissions. Those in opposition fear that this is only the first step and that in the next few years they will begin lowering the emission requirements until eventually smaller sources, as in smaller businesses will fall under the permit program. This, the opposition argues, will have huge and negative impact on an already struggling economy. The EPA and its supporters, however, argue that the regulation of greenhouse gas emissions is a matter of urgency, and this is a well put together regulation aimed directly at doing just that.
