### Attachment B: Definitions

For the purposes of this general permit:

Approval of the Request for Coverage means a reviewing authorit y’ s letter granting a n applicant’s request for

construction or modification, and operation of a true minor source under the terms and conditions of this general

permit.

Biodiesel means a combustion fuel made from fatty acids of methyl esters that complies with the specifications of ASTM

6751

.

Boiler means an enclosed device using controlled flame combustion in which water is heated to recover thermal energy
in the form of steam and/or hot water. Controlled flame combustion refers to a steady

- state, or near steady

- state, process wherein fuel and/or oxidizer feed rates are controlled. A device combus ting solid waste, as defined in §241.3 of

this chapter, is not a boiler unless the device is exempt from the definition of a solid waste incineration unit as provided

in section 129(g)(1) of the CAA. Process heaters are excluded from the definition of Boil er

.

Cause means with respect to the reviewing authority’s ability to terminate a permitted source’s coverage under a permit

that :

1. The p ermittee is not in compliance with the provisions of this g eneral p ermit;

2. The reviewing authority determines that the emissions resulting from the construction or modification of the

permitted source significantly contribute to NAAQS violations, which are not adequately addressed by the

requirements in this g eneral p ermit.

3. The reviewing authority has reasonable cause to believe that the p ermittee obtained Approval of the Request

for Coverage by fraud or misrepresentation.

4. The p ermittee failed to disclose a material fact required by the Request for Coverage or the regulations

ap plicable to the permitted source of which the applicant had or should have had knowledge at the time the

p ermittee submitted the Request for Coverage.

Construction means any physical change or change in the method of operation including fabrication, erect ion,

installation, demolition, or modification of an emission unit that would result in a change of emissions.

Distillate f

uel means fuel oils, including recycled oils that comply with the specifications for fuel oil numbers 1 and 2, as

defined by ASTM 39 6, or equivalent

.

Natural g as means a mixture of hydrocarbons that is a gas at standard conditions and is either composed of at least 70

percent methane by volume or has a gross calorific value of between 950 and 1150 B tu per dry standard cubic foot

.

Permittee means the owner or operator of a permitted source.

Permitted s ource means each boiler for which a reviewing authority issues an Approval of the Request for Coverage.

Process heater means an enclosed device using controlled flame, and the unit's primary purpose is to transfer heat

indirectly to a process material (liquid, gas, or solid) or to a heat transfer material (e.g., glycol or a mixture of glycol and

water) for use in a process unit, instead of generating steam. Process heaters are devices in which the combustion gases
do not come into direct contact with process materials. Process heaters include units that heat water/water mixtures for

pool heating, sidewalk heating, cooling tower water heating, power washing, or oil heating.General Permit for Boilers Page 13 of 14

Version 1. 0 Request for Coverage means a permit application that contains all the information required in the standard application

form.

Standard c ubic f

oot means a measure of the quantity of a gas equal to a cubic foot of volume at a temperature of 68 °F

and a pressure of 29.92 in ches of mercury.General Permit for Boilers Page 14 of 14
