According to a report released last week by Environment America, power plants were responsible for 42% of the CO2 emitted in the United States in 2007, substantially more than any other sector, including transportation. What’s the explanation? Largely, it’s the age of the United States power plants. The report, based on EPA data, states that 73% of power plant CO2 emissions came from plants operating since prior to 1980.
What’s the solution to this problem, in the absence of cap-and-trade legislation enacting? EPA’s already told us, and we shouldn’t be surprised – promulgation of EPA’s “Tailoring Rule,” subjecting existing facilities emitting more than 25,000 tons per year of CO2e to EPA’s New Source Review program.
And what’s the problem with this solution? To a significant degree, it’s that it is the NSR program that got us in this mess in the first place. As my friend Rob Stavins has noted, regulatory programs – such as NSR – that impose different requirements based on the age of a facility, known in the lingo as “vintage-differentiated regulations” or “VDR”, not surprisingly lead to the perverse result that older, more-polluting, facilities stay in service longer than if regulations were imposed in an even-handed manner on different vintages of facilities. In other words, we have the NSR program to thank for the situation described in the Environment America report.
Can anyone doubt, therefore, that application of NSR rules to GHGs will cause those who own such facilities to try to operate them as long as possible without implementing any “modifications” that would trigger application of NSR? Moreover, can anyone doubt that application of NSR rules to new facilities would give old facilities a further cost advantage? Sure, EPA can try to tighten the NSR rules and continue to pursue NSR enforcement cases in order to discourage existing facilities from disguising “life-extension” projects as routine maintenance. However, it’s still a jury-rigged system at best. After all, the program is called New Source Review for a reason.
I’m just a poor country lawyer, but I still think that a cap-and-trade program is a better solution for all sides. Add a traditional three-pollutant piece to it, trade that for elimination of the NSR program in its entirety, and you’d really have something.
Still dreaming, I know.
