US regional review
The following is a summary of significant US environmental issues and legislation or regulations affecting the group.
Clean Air Act and its regulations require, among other things, stringent air
emission limits and operating permits for chemicals plants, refineries, marine
and distribution terminals; stricter fuel specifications and sulphur reductions;
enhanced monitoring of major sources of specified pollutants; and risk management
plans for storage of hazardous substances. This law affects BP facilities producing,
storing, refining, manufacturing and distributing oil and products as well as
the fuels themselves. Federal and state controls on ozone, particulate matter,
carbon monoxide, benzene, sulphur, MTBE, nitrogen dioxide, oxygenates and Reid
Vapor Pressure affect BPs activities and products in the US. BP is continually
adapting its business to these rules, which are subject to recent change. Beginning
January 2006, all gasoline produced by BP was subject to the EPAs stringent
low-sulphur standards. Furthermore, by June 2006, at least 80% of the highway
diesel fuel produced each year by BP was required to meet a sulphur cap of 15
parts per million (ppm) and 100% with effect from January 2010. By June 2007,
all non-road diesel fuel production had to meet a sulphur cap of 500ppm and
15ppm by June 2012. With effect from January 2011, EPAs Mobile Source
Air Toxics regulations will require a refinery annual average benzene level
of 0.62 volume percentage on all gasoline.
at all sites where it has been identified as a PRP or is otherwise named and has established provisions accordingly. BP does not anticipate that its ultimate exposure at these sites
individually, or in aggregate, will be significant, except as reported for Atlantic Richfield Company in the matters below.
