## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve the 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 (NO<INF>X</INF>) emission limit from the R-1 HC Reactor Heater (R-1 Heater), a BART-eligible source currently subject to BART emission limits on NO<INF>X</INF>. To offset the increase in NO<INF>X</INF> emissions from this emission unit, the NO<INF>X</INF> emission limits on the 1st Stage Hydrocracker Fractionator Reboiler (R- 1 Reboiler), also a BART-eligible source subject to BART emission limits on NO<INF>X</INF>, will be reduced. The net effect of these changes is a decrease of 10.4 tons per year (tpy) of allowable NO<INF>X</INF> emissions from sources subject to BART at the BP Cherry Point Refinery.
