  • On  April 16, 2008 the Environmental Protection Agency (EPA) took direct final action to amend its rule to reduce emissions of toxic air pollutants from facilities that distribute organic liquids other than gasoline.  The liquids contain compounds that are emitted as toxic air pollutants.  Toxic air pollutants, also known as air toxics, are known or suspected to cause cancer and other health problems.
  • Organic liquids distribution takes place at liquid terminal facilities, organic chemical manufacturing facilities, petroleum refineries, crude oil pipeline pumping and breakout stations, and other industrial facilities.
  • EPA published a national rule to limit emissions of toxic air pollutants from these operations in 2004.  That rule is one of 96 rules called maximum achievable control technology (MACT) standards that require 174 industry sectors to eliminate 1.7 million tons per year of toxic air pollutants.  Congress listed these toxic air pollutants in the Clean Air Act.
  • The 2004 standards reduce emissions of toxic air pollutants by approximately 3,500 tons per year.
  • These direct final amendments:
    • Clarify combustion control device compliance requirements, certain storage tank control compliance dates, and vapor balance system-monitoring requirements.
    • Correct typographical errors in the rule text.
  • EPA is taking direct final action on these amendments and they are effective within 90 days of publishing in the Federal Register without further notice, unless EPA receives adverse comment within 45 days of publishing in the Federal Register. If we receive adverse comment, we will publish a timely withdrawal in the Federal Register informing the public that these amendments, or the relevant provisions of these amendments, will not take effect.


  • Organic Liquids Distribution facilities subject to today's amendments are already required to reduce emissions of toxic air emissions.  The final amendments do not change the level of control required by the 2004 rule.
  • There are no costs associated with the rule amendments.
