Subject: | BTEX addendum |
Posting from "Don Zweifel" <zweifel@nexus.chapman.edu> Peter, As a clarification may we say that 1% of the TPH (total petroleum hydrocarbon) volume of JP-5 jetfuel is benzene. On an added note, the `E' in BTEX stands for ethylbenzene. This constituent of jetfuel is known to be moderately water soluble and volatile. It has a biochemical decay coefficient identical to benzene and has been classified as a priority pollutant by the USEPA. The risk to human health in regards to water and fish ingestion is expressed as moderately high for ethylbenzene and moderate for benzene and very high for toluene. According to 33 USCA (US Code Annotated) section 1317 of the Clean Water Act, "Such published effluent standard shall take into acct the toxicity of the pollutant, its persistence, degradability" and etc. Subsection (3): Each such effluent standard shall be reviewed and if appropriate, revised every three years. Section 134 : Permits for discharge of pollutants. The administrator may after opportunity for public hearing, issue a permit for the discharge of any pollutant or combination of pollutants... One may conjecture that there may be exceptions to enforcement but evidently only on a case by case basis. If anyone on the net can augment this argument pls come aboard and give us a hand.
