Approval of Regional Haze BART Alternative Measure: Washington

The Environmental Protection Agency (EPA) is proposing to approve a Best Available Retrofit Technology (BART) alternative measure for the BP Cherry Point Refinery located near Ferndale, Washington. The BART alternative measure increases the oxides of nitrogen (NOX) emission limit from the R-1 HC Reactor Heater (R-1 Heater), a BART-eligible source currently subject to BART emission limits on NOX. To offset the increase in NOX emissions from this emission unit, the NOX emission limits on the 1st Stage Hydrocracker Fractionator Reboiler (R-1 Reboiler), also a BART-eligible source subject to BART emission limits on NOX, will be reduced. The net effect of these changes is a decrease of 10.4 tons per year (tpy) of allowable NOX emissions from sources subject to BART at the BP Cherry Point Refinery.
