Of 1.5 million boilers in the U.S., less than 1% will need to meet numerical emission limits under the Boiler NESHAPs

<1% (about 2,300) would need to

meet numerical emission limits to minimize toxics Most of these are minimize toxics. Most of these are larger boilers located at industrial facilities.

13% (about 197,000) would

need to follow work practice standards such as annual tune

~197,000 covered by rules

~1.3 million boilers not covered by rules standards, such as annual tune ups, to minimize toxics.

86% are clean and not covered by 86% are clean and not covered by

these rules. Many of these boilers are at places like hospitals, schools and churches.

Connecticut Boilers

In 2011, there were ~40,000 non‐ residential boilers / hot water heaters registered at ~14,000 sources in CT.

Why is EPA regulating Boilers?

T d i i i d h h l h To reduce toxic emissions and protect human health

• Burning biomass, coal, and oil results in emissions of mercury,

dioxin, furans, formaldehyde, lead, and hydrochloric acid.

• Health effects are significant:

– Mercury can cause adverse effects on children’s developing brains, including effects on IQ, learning and memory. Air toxics can cause cancer and other serious health effects in adults – Air toxics can cause cancer and other serious health effects in adults and children. – Controlling air toxics will also reduce fine particle pollution and carbon monoxide.

• Fine particles are linked to serious cardiovascular and

respiratory effects, even premature death.

• Carbon monoxide reduces oxygen delivery to heart and

yg y brain, can cause angina and other problems for people with heart disease.

Connecticut Department of Energy and Environmental Protection Connecticut Department of Energy and Environmental Protection

Area Sources – What are they?

• Small stationary sources of air toxics

A th t it h d i

• Any source that emits some hazardous air

pollutant (HAP) but is not a major source of HAP HAP

• “Has a potential to emit less than 10 tpy for a

Has a potential to emit less than 10 tpy for a single HAP or less than 25 tpy for combined HAP” HAP

Connecticut Department of Energy and Environmental Protection Connecticut Department of Energy and Environmental Protection

Are Source Boiler Rule: Applicability A li t f ilit hi h it h

• Applies to an area source facility which emits or has

potential to emit less than 10 tons per year (tpy) of any single HAP and less than 25 tpy of any b f combination of HAP.

• Expected to apply to about 183,000 boilers located

i il t i l f iliti ( h t l ffi primarily at commercial facilities (e.g., hotels, office buildings, restaurants) and institutional facilities (e.g., schools, universities, hospitals, prisons), as well as industrial facilities.

• Rule applies to coal, biomass, and oil‐fired boilers.

Rule does NOT apply to boilers that are gas‐fired, as defined.

Connecticut Department of Energy and Environmental Protection Connecticut Department of Energy and Environmental Protection

Area Source Boiler Rule

• Three subcategories based on design type:

– Coal-fired units

• 3,700 units

2% of area source boilers – 2% of area source boilers – 85% less than 10 million Btu/hr – Biomass-fired units

• 11,000 units

Energy Conservation Requirements

• EPA has established pollution prevention (P2) as one of its highest
• priorities. One opportunity for P2 lies in simply using energy efficient

technologies to minimize emissions.

• Tune-ups

– Applicable to small coal-fired boilers < 10 MMBtu/hr, all biomass-fired boilers, and all oil-fired boilers. – Rationale – by improving combustion efficiency, fuel usage is reduced which results in decreased emissions.

• Energy Assessment

– Applicable to existing large boilers > 10 MMBtu/hr, except limited use boilers (with a federally enforceable capacity factor of no more than 10 percent) Provides valuable information on improving energy efficiency – Provides valuable information on improving energy efficiency – Leads to reductions in emissions through process changes and other efficiency modifications but energy conservation measures identified are not required to be implemented

Energy Assessment Requirements

Energy assessments must evaluate the:

• Boiler system

1 Boiler; and

• 1. Boiler; and
• 2. Associated components, such as, the feedwater systems, combustion air

systems, fuel systems (including burners), blowdown systems, combustion control systems, steam systems, and condensate return systems, directly connected to and serving the energy use systems

• Energy use systems (meeting energy production threshold)
• 1. Process heating; compressed air systems; machine drive (motors, pumps, fans);

g; p y ; ( , p p , ); process cooling; facility heating, ventilation, and air conditioning systems; hot heater systems; building envelope, and lighting; or

• 2. Other systems that use steam, hot water, process heat, or electricity, provided by

h ff d b il the affected boiler

• 3. Energy use systems are only those systems using energy clearly produced by

affected boilers.

Energy Use Systems

• Does not encompass energy use systems using purchased

electricity from an off‐site source electricity from an off site source

• Limited to energy use systems:

– Located on‐site; and – Associated with the affected boiler

• Energy use systems may be segmented in the most logical

manner as applicable to specific facility being assessed manner as applicable to specific facility being assessed

– e.g., heating and cooling system, compressed air systems, production area, or a specific building

Connecticut Department of Energy and Environmental Protection Connecticut Department of Energy and Environmental Protection

Energy Assessment Requirements

• Boiler Annual Heat Input

– Heat input capacity for each boiler calculated based on 8,760 hr/yr – A measurement of the facility’s total boiler capacity A measurement of the facility s total boiler capacity

• Add together heat input capacity for each boiler subject to energy assessment

requirement

– Measured in Trillion Btu/yr (TBtu/yr)

• Example:

A facility has two (2) existing oil‐fired boilers, each with a heat input capacity of 10 MMBtu/hr capacity of 10 MMBtu/hr. The facility’s Boiler Annual Heat Input would equal: 2 x (10,000,000 Btu/hr x 8,760 hr/yr) = 175,200,000,000 Btu/yr 0 1752 TBt /

• r 0.1752 TBtu/yr

Connecticut Department of Energy and Environmental Protection Connecticut Department of Energy and Environmental Protection

EA Requirements (cont’d)

• Using our previous example:

Th t b il id t fi (5) di ti t t The two boilers provide energy to five (5) distinct energy use systems, each consuming 20% of the boilers’ output. With Boiler Annual Heat Input (0.1752 TBtu/yr) < 0.3 Tbtu/yr, only the boilers would need to be included in an energy assessment because none

• f the energy use systems meet or exceed the 50% threshold.

If, the two boilers provide energy to one (1) energy use system, consuming 100% of the boilers’ output, the boilers and the energy use system would have to be evaluated in an energy assessment.
