EPA's Revision to the 40 CFR Part 136 Method Detection Limit (MDL) Procedure

EPA's Revision to the 40 CFR Part 136 Method Detection Limit (MDL) Procedure

Tuesday, January 23, 2017 - 1:30 P.M. EST

About This Webinar:

The Method Detection Limit (MDL) procedure was published in 1984 and since then has been a source of considerable confusion and disagreement. It is, however, used almost universally as the procedure for determining detection limits in environmental testing. 

On February 19th 2015, the EPA published a major revision to the MDL procedure, the first significant revision since the original publication. Following an extended approval process, the update was signed by EPA Administrator Scott Pruitt on Tuesday, August 8th and was published in the Federal Register in September. Following publication there is a 30 day implementation period. This webinar will cover the changes to the MDL, the reasons for change and the impacts on data users and laboratories.

Topics Presented:

  • Changes to the MDL procedure
  • Reasons for change
  • Impacts on laboratories and how laboratories should prepare
  • Overall impacts on detection limits and how this could impact regulated industry and other data users

Who Should Attend?

  • Regulated Industry and Data Users - Managers responsible for environmental compliance
  • Laboratory Managers and Quality Assurance officials
  • Regulatory Officials
  • Data Validators

A question and answer session will immediately follow the presentation. At the conclusion of each webinar, you will be asked for your feedback and opinions for future webinar topics to be developed by TestAmerica.
