White House to review Clean Air Transport Rule

The proposed Clean Air Transport Rule has been sent to the White House for review, and the final rule is expected to be issued in July.

The Environmental Protection Agency (EPA) yesterday sent its final transport rule to the Office of Management and Budget. The rule is expected to replace the current Clean Air Interstate Rule's (CAIR) SO2 and NOx trading programs in 2012.

A federal court in 2008 overturned CAIR for what it said were violations of the Clean Air Act, but the rule has remained in effect until EPA could rewrite it in compliance with the court's decision.

The transport rule will develop new trading rules for the SO2 and NOx markets and allocate new allowances. Existing SO2 and NOx allowances will not be eligible for compliance under the new programs.

EPA proposed the transport rule in July 2010 and has since issued several new data sets including new emissions projections and allowance allocation methodologies. Many in the industry have called on the agency to issue a new proposal that accounts for the different data, which EPA has said will be considered as it develops the final rule.

EPA's SO2 and NOx allocations were among the provisions the federal court found to violate the Clean Air Act. The agency tried to change the value of SO2 allowances by requiring utilities to surrender two allowances for each ton emitted, when Congress had said they are worth a full ton. And for NOx, EPA used “fuel factors,” which gave more allowances to more emissions-intensive facilities.

EPA “proposed two different allocations schemes for SO2 allowances and neither one of the proposals is really all that attractive from a legal standpoint.,” said Jeff Holmstead, lawyer with Bracewell and Giuliani and former assistant EPA administrator.

One method would allocate allowances to natural gas plants which “have no compliance obligations so it is just free money for them,” Holmstead said. Some companies have roughly equal coal and natural gas capacities, but others are more coal-intensive and would not be able to transfer allowances from any inherently lower-emitting plants. He said he had seen data suggesting it could cost about $350mn/yr to transfer from coal to natural gas.

The second allocation plan is similar to the one used in CAIR, which is based on emission projections from a set model of plants, rather than predicting specific sources' emissions.

Traders have seen bids for transport rule SO2 allowances at $1,500/st and NOx allowances between $5,000 and $10,000/st, but variable NOx control costs have been seen closer to $500, level with EPA estimates.

EPA has estimated compliance with the transport rule would cost $2.8bn in 2014, when more stringent caps are set for SO2 in some states. The NOx caps will be steady, but state-specific caps will be enforced in 2014 which could limit interstate trading. If a state's cap is exceeded, any company that exceeds its allocation there would face penalties, even if it holds enough allowances to cover its emissions. Some market participants have said utilities could be willing to pay double for in-state SO2 allowances, in an effort to keep the state within its cap.

EPA has also proposed what some say are more stringent rules, such as the utility air toxics rule that requires coal- and oil-fired electric generators to install maximum available control technology to reduce hazardous air pollutants such as mercury and lead.

Utilities are likely to need to install SO2 scrubbers to meet the air toxics rule which is expected to “crush SO2 prices but leave NOx virtually unaffected,” one trader said.
