  • EGU MATS HCl Quarterly Testing News - Audit Sample Program  (10/28/19)

Earlier this summer, EPA posted a notice regarding a lack of providers for audit samples as part the audit sample program under 40 CFR Parts 60 and 63.  As a reminder, use of audit samples are required if the audit samples are "commercially available" from two or more independent accredited audit sample providers (AASP).  Since there are no longer two providers, the requirement to obtain these audit samples is no longer in effect until another indepedent AASP has audit samples for purchase.   What does this mean in practice for many is EGU MATS affected sources?  Those sources performing quarterly stack testing for HCl no longer need to acquire blind audit samples for quarterly performance tests (e.g sources using Reference Method 26A for HCl stack testing).  Finally, EPA has stated that they will post an update with the name(s) of the providers and audit sample(s) available for purhaase when there are two or more AASP.  Once that post occurs, the audit sample program will go back into effect 60 days after the post has been made.

  • EPA Finalizes ACE Rule and Clean Power Plan Repeal  (7/8/19)

In today's Federal Register, dated July 8, 2019 (Volume 84, No. 130 - 65 total pages), EPA has finalized the Affordable Clean Energy rule ("ACE Rule") and formally repealed the Clean Power Plan (CPP).  A copy of the final rule can found in our FTP library.


  • Update on EPA's Combustion Turbine NESHAP  (4/12/19)

On April 12, 2019, EPA published in the Federal Register a proposed rule titled, “National Emission Standards for Hazardous Air Pollutants: Stationary Combustion Turbines Residual Risk and Technology Review.”  EPA initially issued its NESHAP rule for Stationary Combustion Turbines on March 5, 2004.  The rule applies to stationary combustion turbines located at major sources of hazardous air pollutants (HAP).  The NESHAP requires new or reconstructed stationary combustion turbines to meet a formaldehyde limit of 91 parts per billion by volume, dry basis at 15 percent oxygen.  However, EPA stayed the effectiveness of the rule on August 18, 2004.  A copy of the proposed rule can found in our FTP library.

Following a residual risk and technology review conducted pursuant to the Clean Air Act (CAA), EPA is proposing to determine that risks from the source category are acceptable and that no new cost-effective controls are available.  In the proposed rule, EPA is also:


    • Revising the requirements for periods of startup, shutdown and malfunction (SSM) to be consistent with recent court decisions;
    • Requiring electronic reporting of performance test results and compliance reports; and
    • Lifting the stay of the standards for new gas-fired stationary combustion turbines, which has been in effect since August 2004.           


  • EPA Proposes Reconsideration of Supplemental MATS Finding  (2/7/19)

In today's Federal Register, dated February 7, 2019 (Volume 84, No. 26 - 35 total pages), EPA has proposed their reconsideration of supplemental finding and resisdual risk and technology review of the MATS rule.  At this time it's unclear what the ultimate outcome of this new finding would mean for the industry.  Comments are due by April 8, 2019.   There will also be a public hearing concering this proposed rule.  The time and location of the public hearing will be announced in a subsequent Federal Register notice.  A copy of the proposed rule can found in our FTP library.
