On November 20, 2019, the United States Environmental Protection Agency (USEPA) finalized revisions to AP-42 Chapter 7, Section 7.1 – Organic Liquid Storage Tanks, which provides approved emission estimating methodologies for storage tanks. Additional revisions were incorporated in March 2020. The methodologies include emission estimates for working and breathing (standing) losses, but not for flashing losses. The revisions include:


  • Updated meteorological data.
  • Replaced equations historically used to obtain approximate values with more accurate equations.
  • Addition of methodology for estimating losses from tank cleaning.
  • Working loss emission calculations based on changes in liquid level rather than throughput.
  • Revised the tank condition and color inputs and updated associated equations.
  • Addition of separate calculations for uninsulated, partially insulated, or fully insulated tanks.


The EPA TANKS 4.09d emissions estimation software program has now become obsolete. This program has not been supported by USEPA for several years, it is known to have errors, and it does not include the recent changes to AP-42 Chapter 7. As of April 9, 2020, the Oklahoma Department of Environmental Quality (ODEQ) has requested that applicants discontinue the use of TANKS 4.09d for all air permit application submissions.


The AP-42 Chapter 7, Section 7.1 methodology revisions may result in increased or decreased emission estimates depending on the type of tank and operating scenario at the individual facility. It is expected that most emission estimates will remain close to the previously estimated values, however it is possible to have significant changes which may need to be discussed with the regulatory agency.

Coal Combustion Residuals Regulation (January 22, 2018) – Coal combustion residuals, commonly known as coal ash, are created when coal is burned by power plants to produce electricity. Coal ash is reportedly one of the largest types of industrial waste generated in the United States. This regulation for the disposal of coal combustion residuals from electric utilities became effective on October 4, 2016 and provides a comprehensive set of requirements for the safe disposal of CCRs, commonly known as coal ash, from coal-fired power plants. The regulation establishes technical requirements for CCR landfills and surface impoundments under Subtitle D of RCRA and addresses the risks from coal ash disposal — leaking of contaminants into ground water, blowing of contaminants into the air as dust, and the catastrophic failure of coal ash surface impoundments. Additionally, the requirements for recordkeeping and reporting as well as the requirement for each facility to establish and post specific information to a publicly-accessible website are established. This regulation also supports the responsible recycling of CCRs by distinguishing safe, beneficial use from disposal.
