Deadline Alert: Major Source Boiler MACT Energy Assessments

Deadline Alert: Major Source Boiler MACT Energy Assessments

If you are (or could be) a major source of Hazardous Air Pollutant emissions and have one or more boilers that can burn natural gas, oil, or solid fuel, and have a rated input of greater than 10 MMBtu, you may need to conduct a one-time energy assessment. Boilers subject to EPA’s Major Source Boiler MACT requirements (40 CFR 63 Subpart DDDDD) must have an energy assessment performed prior to January 31, 2016 to certify that they meet “acceptable standards.”

Achieving Compliance

Woodard & Curran provides everything you need to comply with the upcoming major source Boiler MACT requirements, and we provide critical information to make smart investments in energy efficiency. This includes our detailed report, an Initial Notification of Applicability, preparation of your Notification of Compliance Status, and support throughout the submission process. Our goal is to make the energy assessment and submission easy for you.

Comprehensive Energy Assessments

The certification letter is just part of the benefit of conducting a thorough energy assessment. As one of the few EPA-qualified energy assessors in the country, Woodard & Curran has a proven track record of helping clients address issues beyond meeting the requirements of the Boiler MACT rules. Our engineers have extensive experience in industrial/utility settings and energy-use analyses and we equip our clients with the tools and technology needed to identify all energy saving opportunities, from building envelope improvements, to compressed air system leaks, to upgrading equipment and control systems. All assessments are reviewed, approved, and stamped by one of our Certified Energy Managers (CEM).

Typical recommendations and findings include:

  • Fuel monitoring plans
  • Air compressor upgrades or compressed air system modification
  • Identification and uses for thermal heat recovery
  • System electrical load reduction opportunities
  • Identification of applications and savings from VFD upgrades
  • Boiler O2 trim or combustion control upgrades
  • Equipment control optimization
  • Outside air reset or compensation for heating systems
  • Identification of thermal energy losses
  • Equipment or system obsolescence upgrade recommendations

Our reports detail the estimated costs of implementing energy-saving measures and provide prioritized recommendations based on the emissions and energy reduction and expected payback of the investments.

We help our clients save as much operating costs as possible with minimal capital investment, and we strive to recover their investment in upgrades in less than 3-5 years.
