Managing DAS & CEMS Systems: Top 5 Challenges and Solutions

Updated Original Post Dated: April 23, 2019

Compliance Managers can only be effective if the data they’re accessing is current and thorough. Multiple regulations coming into play, outdated DAS, or incomplete testing are just some of the many challenges Compliance Managers face.

When overcoming these challenges, if you document the solutions the lessons learned can be invaluable tools for future reference and training new employees. With that in mind, we’ve assembled the top 5 challenges faced when managing DAS and CEMS systems — and recommended solutions to address the issue.

Challenge: Late or Incomplete QA Test
Solution: Be Proactive with Tracking QA Test Deadlines

Missed or incomplete testing can result in excessive downtime. Excessive downtimes can be very expensive for sources in trading programs such as ARP, SIP, CSAPR, and RGGI. One way to combat these challenges is to be proactive with tracking QA test deadlines – don’t wait for ECMPS to tell you. Having a thorough understanding of what qualifies for an extension and/or grace period can help ensure you’re conducting and submitting information on time.

The CEMLink 6 compliance calendar and QA test deadline features allow users to track and monitor Part 60 ongoing QA tests in addition to inspection and site-specific operating limits (SSOL) required by many MACT regulations. Learn how to use these helpful tools in this pre-recorded webinar, available for download here.Read more »
