Multiple Sources Under Common Ownership.
(a) For the purposes of this section,
"bubble" means an option taken by the owner of 2 or more stationary

owner’s stationary sources while simultaneously imposing controls that are less
stringent than RACT level on other emissions units at the same or other of the
owner’s stationary sources, including the option of no controls on such units,

the state implementation plan (SIP) in a more cost effective manner.
(b) Emissions averaging shall be allowed for NOx
emissions from 2 or more stationary sources only if all of the requirements of
this section are met.
(c) All of the stationary sources to be included in
the emissions averaging shall be:

New Hampshire; and
(2) Under the
control of a single owner.

allowable emission averaging periods, shall be done in accordance with EPA's emissions
trading policy, as described at 51 FR 43814 and 51 FR 43850.

(g) The recordkeeping and reporting requirements for
emission averaging shall:
(1) Be in
accordance with Env-A 900; and

emissions averaging shall calculate the total allowable NOx emissions using the
equation specified in Env-A 1314.05 for each 24-hour calendar day. Compliance with the NOx RACT weighted average
allowable emission rate so calculated shall be based on the weighted average
actual NOx emissions from the emissions unit(s) that are operating on a given
day.
(i) Emission reduction
credits generated from reductions at any stationary source
included in emissions averaging may be used for compliance with the total
allowable NOx emissions calculated pursuant to (h), above, by any other

(j) The owner or operator of each stationary
source to be included in the emissions averaging shall:
(1) Calculate
daily emissions:

NOx per million Btu, as specified in Env-A 1303 through Env-A 1312 for all
emissions units and fuels in use prior to December 31, 1990.
(d) Annual NOx emissions limits shall be based on
the lower of the actual or allowable NOx emissions for calendar year 1990,
unless NOx emissions and operational data submitted by the owner or operator, and

Definitions
40 CFR 60, subpart BBBB:
Section 60.1940:
“Startup period” means the period when a municipal
waste combustion unit begins the continuous combustion of municipal solid
waste. It does not include any warmup period during which the municipal
waste combustion unit combusts fossil fuel or other solid waste
fuel but receives no municipal solid
waste..
40 CFR 60, subpart IIII:
All terms that are used in this subpart and are not
defined below are given the same meaning as in the Act and in subpart A of this
part.
Section
60.4219:
“Spark ignition” means relating to a gasoline, natural
gas, or liquefied petroleum gas fueled engine or any other type of engine with
a spark plug (or other sparking device) and with operating characteristics
significantly similar to the theoretical Otto combustion cycle. Spark ignition
engines usually use a throttle to regulate intake air flow to control power during
normal operation. Dual-fuel engines in which a liquid fuel (typically diesel
fuel) is used for compression ignition and gaseous fuel (typically natural gas)
is used as the primary fuel at an annual average ratio of less than 2 parts
diesel fuel to 100 parts total fuel on an energy equivalent basis are spark
ignition engines.
“Stationary internal combustion engine” means any
internal combustion engine (ICE), except combustion turbines, that converts heat
energy into mechanical work and is not mobile. Stationary ICE differ from
mobile ICE in that a stationary internal combustion engine is not a nonroad
engine as defined at 40 CFR 1068.30 (excluding paragraph (2)(ii) of that
definition), and is not used to propel a motor vehicle, aircraft, or a vehicle
used solely for competition. Stationary ICE include reciprocating ICE, rotary
ICE, and other ICE, except combustion turbines.
40 CFR 60, subpart JJJJ:
Section 60.4248:
“Lean
burn engine” means any two-stroke or four-stroke spark ignited engine that does
not meet the definition of a rich burn engine.
“Rich
burn engine” means any four-stroke spark ignited engine where the manufacturer's
recommended operating air/fuel ratio divided by the stoichiometric air/fuel
ratio at full load conditions is less than or equal to 1.1. Engines originally
manufactured as rich burn engines, but modified prior to June 12, 2006, with
passive emission control technology for NOX (such as pre-combustion chambers)
will be considered lean burn engines. Also, existing engines where there are no
manufacturer's recommendations regarding air/fuel ratio will be considered a
rich burn engine if the excess oxygen content of the exhaust at full load
conditions is less than or equal to 2 percent.
40 CFR
63, subpart JJJJJJ:
Section
63.11237:
“Temporary
boiler” means any gaseous or liquid fuel boiler that is designed to, and is
capable of, being carried or moved from one location to another by means of,
for example, wheels, skids, carrying handles, dollies, trailers, or platforms.
A boiler is not a temporary boiler if any one of the following conditions
exists:
(1)
The equipment is attached to a foundation.
(2)
The boiler or a replacement remains at a location within the facility and
performs the same or similar function for more than 12 consecutive months,
unless the regulatory agency approves an extension. An extension may be granted
by the regulating agency upon petition by the owner or operator of a unit
specifying the basis for such a request. Any temporary boiler that replaces a
temporary boiler at a location within the facility and performs the same or
similar function will be included in calculating the consecutive time period
unless there is a gap in operation of 12 months or more.
(3)
The equipment is located at a seasonal facility and operates during the full
annual operating period of the seasonal facility, remains at the facility for
at least 2 years, and operates at that facility for at least 3 months each
year.
(4)
The equipment is moved from one location to another within the facility but
continues to perform the same or similar function and serve the same
electricity, steam, and/or hot water system in an attempt to circumvent the
residence time requirements of this definition.
