Boiler MACT


The EPA has issued two rules governing Major and Minor (Area) Sources of Hazardous Air Pollutants (HAPs) for commercial and industrial boilers. Collectively, these rules have been commonly referred to Boiler MACT rules. These rules may impact your facility if you burn fuel oil, biomass, or coal and are a commercial or industrial operation.

Major Sources are those that have the potential to emit 10 tons per year of any single HAP or 25 tons per year of any combination of HAP. Area Sources are any Sources that are not Major Sources. In some cases, the rules place numerical limits on Particulate Matter, Hydrogen Chloride, Mercury, and/or Carbon Monoxide. Depending on size and classification, boilers may be required to have annual, biennial, or 5-year  tune-ups. The rules also require a one time energy assessment for existing boilers at Major Source facilities and existing boilers over 10 mmBtu/hr at Area Source facilities.

WESEE provides consulting services to help you navigate compliance under the Boiler MACT rules. WESEE will help you develop a strategy that considers all compliance options to identify the most cost effective compliance strategy. Please feel free to contact us anytime discuss the implications of these rules for your facility.

• Performance of energy assessments
• Initial setup of reporting and record keeping procedures to ensure ease
of compliance for owners over time

Depending on the overall facility emissions, and combustion unit size, type, and age, a one-time Energy Assessment may be required. WESEE provides Energy Assessments for commercial and industrial clients, and has a history of identifying practical projects providing energy savings, operating cost reductions, and emission reductions. WESEE Energy Assessments satisfy EPA Major Source and Area Source rule requirements and typically include:

• An onsite equipment inspection and evaluation
• Development of the energy conservation measures
• Technical and financial analysis of the energy conservation measures
• A report detailing the findings of the assessment

WESEE utilizes state of the art equipment to provide a detailed understanding of your facility’s energy needs. Capabilities include non-invasive monitoring of Btu usage for hot water and steam systems, current and voltage monitoring, infrared thermography, and flue gas/boiler efficiency monitoring. WESEE’s equipment includes the Flexim Fluxus F601 ultrasonic flowmeter, FLIR E4 thermal camera, and Testo 340 flue gas analyzer.
