OP, you are correct, it is the detractors like Limbaugh & the few on these threads that are oblivious to the events taking place.
the event is eventually cateostrophic, no matter their 'logic' & rationalizations
Lynchburg Ferry—Benzene will be removed from the Lynchburg Ferry APWL. Benzene levels in the Lynchburg Ferry area have been dropping steadily since 2005. Intense inspections, investigations, and enforcement; pollution reduction programs with industry; and coordination with the U.S. Coast Guard have resulted in benzene levels dropping 65% from 2005 through 2008. The current level, .9 parts per billion (ppb), is well below the ESL of 1.4 ppb.
· Texas City—Acrolein, butyraldehyde, and valeraldehyde will be removed from the Texas City APWL. These compounds were placed on the APWL due to odor complaints. Through working with industry, odor complaints have dropped to extremely low levels and ambient concentrations of these chemicals are at levels that are no longer expected to cause nuisance odor complaints.
· Beaumont—Benzene will be removed from the Beaumont APWL. A recent TCEQ health assessment for benzene indicates that the reported annual levels are below those of health concern. For example, the latest year for which data is available, 2008, shows a reading just over .8 ppb, well below the 1.4 ppb ESL. The TCEQ is in the process of relocating the existing monitoring site to a residential area so it will be closer to the recently expanded ExxonMobil facility.
· Corpus Christi—Benzene will be removed from the Corpus Christi APWL, and because it is the only pollutant on the list, the APWL will be removed. Since 2002, benzene levels have been on a steady decline. In 2008, the benzene level was .9 ppb, well below the 1.4 ppb ESL.
