Additional Information

We offer this information packet as a helpful tool which can be part of a larger internal compliance strategy for developing internal procedures and mechanisms for increasing the existence of compliance. You can “cut and paste” elements from these documents into your internal procedures as a starting point for updating your current plans for MATS activities.

ESC does not provide air compliance strategy consultation and you should work with your local regulators to verify the applicability of these suggestions to your system. Individual questions on specific situations should be directed to your local permitting authority, who has delegated authority under the MATS program.

    1. Advance Notice
    2. Conducting Performance Testing or Performance Evaluations
    3. Post Testing
    4. Ongoing Activities
     
  5. Summary of Guidance for the Potential of Using a Back Up or a Separate Startup/Shutdown Sorbent Trap System
    Filename: 2015-May-19_EPA-Potential-ST_BkupSystems_SeparateSUSDSystems.pdf
    The summary provides a copy of a document prepared by Robert Vollaro, from EPA’s Clean Air Market Division (CAMD). It contains the notes from a conference call held on May 19, 2015, between the CAMD and several of the DAHS (Data Acquisition and Handling System) vendors. The purpose of the call was to discuss the Agency’s current thinking regarding the use of data from backup sorbent trap monitoring systems. It should only be considered as guidance, and affected sources should keep their permitting authorities informed of their interpretation and application of backup data from sorbent trap systems.
