B. Processing Monthly QA and Hourly Emission Files

Regulatory references:

This recommendation has no origin in the P75 regulations. The regulations only require the submission of a clean EDR (electronic data reporting) file in the approved EPA format (XML) within the 30-day period following the completion of each calendar quarter. Instead of waiting until the end of the quarter to generate and process the QA (Quality Assurance) and emissions EDR files through ECMPS, it is recommended that you generate and process these EDR files on a more frequent basis, in this case, monthly. Through this process you are breaking up the calendar quarter into smaller and more manageable pieces.

Note: when evaluating an emissions file for a time range less than a full calendar quarter, you will get error messages from ECMPS for the dates not included. You can ignore these message.  For example, if you generated a file for just April, and ECMPS says you did not include records for May and June, that’s OK. Just focus on any errors for the records in April.

Recommendations:
  1. First, be sure you have access to ECMPS (Emission Collection and Monitoring Plan System) through the client tool. Each time you open up the client tool, it will attempt to synch up with the EPA’s host computer network to ensure that your version of the software is up to date. Provided below is a link to ECMPS’ home page: https://ecmps.camdsupport.com/index.shtml

  2. The first step is to evaluate the QA records for your unit first. The QA file generally has the data and results for any linearities or RATAs performed so far in that quarter. So, if a linearity or RATA has not been performed, the file will be empty. But, you still should generate an QA file and run it through ECMPS to make sure you are not carrying over any strange error messages from the last quarter. Any errors messages generated from ECMPS while processing the QA file must be addressed and corrected in StackVision (SV). 

  3. For the month (or period of time you are going to review), look over the daily operating reports (see tip A earlier in this document), looking for any error messages associated with these report. Also, look at the data values. Do they look normal or typical? Besides using these reports, sometimes looking at a graph in SV of load (MWs or steam flow), concentrations of NOx, CO2, SO2 or flow rates can be helpful. If similar operating conditions (load or steam flow) are roughly duplicated, then roughly the same emission concentrations and readings should be recorded.

  4. If the reports look OK and you think you are ready, then generate a QA EDR file.  (Tools > QA and Certification > Part 75). Generate a QA file and save it to a known location.

  5. Open up ECMPS and import the QA file you’ve generated and evaluate it. If the Evaluation report shows one or more errors, you will need to address them in SV, correcting the QA records and re-generating a new file. Re-import the QA file and evaluate it again in ECMPS. Continue this process until no errors are found in the QA file.

  6. When the Evaluation Report comes back with no errors for the QA file, then you are ready to generate an emissions file.  Repeat steps #4 and #5 until the evaluation report from ECMPS is now clean for the date range included.

  7. Breaking up the calendar quarter into smaller pieces makes it much easier to manage and less stressful at the end of the quarter.
