(a) Purpose
T he purpose of Rule 1110.2 is to reduce Oxides of Nitrogen (NO x ), Volatile Organic Compounds (VOCs), and Carbon Monoxide (CO) from engines.

(b) Applicability All stationary and portable engines over 50 rated brake horsepower ( bhp ) are subject
to this rule.

(c) Definitions For the purpose of this rule, the following definitions shall apply: (1) AGRICULTURAL STATIONARY ENGINE is a non

- portable engine used for the growing and harvesting of crops or the raising of fowl or animals for the primary purpose of makin g a profit, providing a livelihood, or conducting agricultural research or instruction by an educational institution. An engine used for the processing or distribution of crops or fowl or animals is not an agricultural engine. (2) APPROVED EMISSION CONTRO L PLAN is a control plan, submitted on or before December 31, 1992, and approved by the Executive Officer prior to November 14, 1997, that was required by subdivision (d) of this rule as amended September 7, 1990

- IGNITION ENGINES mean engines certified by California Air Resources Board (CARB) to meet emission standards in accordance with Title 13, Chapter 9, Article 4.5 of the California Code of Regulations (CCR). (4) EMERGENCY STANDBY ENGINE is an engine which operates as a
temporary r eplacement for primary mechanical or electrical power during periods of fuel or energy shortage or while the primary power supply is under repair.Rule 1110.2 (Cont.) (Amended February 1, 2008)

1110.2

- 2 (5) ENGINE is any spark

- or compression

- ignited internal combustion engine, including engines used for contro l of VOCs, but not including engines used for
self

- propulsion. (6) EXEMPT COMPOUNDS are defined in District Rule 102

- Definition of
Terms. (7) FACILITY means any source or group of sources or other air contaminant emitting activities which are located on one or more contiguous properties within the District, in actual physical contact or separated solely by a public roadway or other public right

- of

- way, and are owned or operated by the same person (or by persons under common control), or an outer continent al shelf (OCS) source as determined in Section 55.2 of Title 40, Part 55 of the Code of Federal Regulations (40 CFR Part 55). Such above

- described groups, if noncontiguous, but connected only by land carrying a pipeline, shall not be
considered one facili ty. Sources or installations involved in crude oil and gas production in Southern California Coastal or OCS Waters and transport of such crude oil and gas in Southern California Coastal or OCS Waters shall be included in the same facility which is under t he same ownership or use entitlement as the crude oil and gas production facility on

- shore. (8) LEAN

- BURN ENGINE means an engine that operates with high levels of

excess air and an exhaust oxygen concentration of greater than 4 percent. ( 9 ) LOCATION means any single site at a building, structure, facility, or installation. For the purpose of this definition, a site is a space occupied or to be occupied by an engine. For engines which are brought to a facility to perform maintenance on equipment at its per manent or ordinary location, each maintenance site shall be a separate location. ( 10 ) NET ELECTRICAL ENERGY means the electrical energy produced by a generator, less the electrical energy consumed by any auxiliary equipment necessary to operate the engine generator and, if applicable, any heat recovery equipment, such as heat exchangers. ( 11 ) NON

- ROAD ENGINE is any engine, defined under 40 CFR Part 89, that
does not remain or will not remain at a location for more than 12 consecutive months, or a shorter pe riod of time where such period is representative of normal annual source operation at a stationary source that resides at a fixed location for more than 12 months (e.g., seasonal operations such as canning facilities), and meets one of the following:Rule 1110.2 (Cont.) (Amended February 1, 2008)

1110.2

- 3 (A) I s used in or on a piece of equipment that is self

- propelled or serves a dual purpose by both propelling itself and performing another function (such as a mobile crane); or (B) Is used in or on a piece of equipment that is intended to be propelled while per forming its function (such as lawn mowers and string trimmers);

or (C) By itself, or in or on a piece of equipment, is portable or transportable, meaning designed to be and capable of being carried or moved from one location to another. Transportability i ncludes, but is not limited to, wheels, skids, carrying handles, dolly, trailer, platform or mounting. (12) OPERATING CYCLE means a period of time within which a round of regularly recurring events is completed, and cannot be stopped without the risk
of en dangering public safety or health, causing material damage to the equipment or product, or cannot be stopped due to technical constraints.
Economic reasons alone will not be sufficient to extend this time period. The operating cycle includes batch proces ses that may start and finish several times within a twenty

- four hour period, in which case each start to finish interval is considered a complete cycle. ( 1 3 ) OXIDES OF NITROGEN (NOx) means nitric oxide and nitrogen dioxide. (1 4 ) PORTABLE ENGINE is an engi ne that, by itself or in or on a piece of equipment, is designed to be and capable of being carried or moved from one location to another. Indications of portability include, but are not limited to, wheels, skids, carrying handles, dolly, trailer, platfor m or mounting. The operator must demonstrate the necessity of the engine being periodically moved from one location to another because of the nature of the operation. An engine is not portable if: (A) the engine or its replacement remains or will reside a t the same location for more than 12 consecutive months. Any engine, such as a back

- up or stand

- by engine, that replaces an engine at a location and is intended to perform the same function as the engine being replaced, will be included in calculating the consecutive time period. In that case, the cumulative time of both engines, including the time between the removal of the original engine and installation of the replacement engine, will be counted toward the consecutive time period; orRule 1110.2 (Cont.) (Amended February 1, 2008)

1110.2

- 4 (B) the engine re

mains or will reside at a location for less than 12 consecutive months where such a period represents the full length of normal annual source operations such as a seasonal source; or (C) the engine is removed from one location for a period and then it or i ts equivalent is returned to the same location thereby circumventing the portable engine residence time requirements. The period during which the engine is maintained at a designated storage facility shall be excluded from the residency time determination. (1 5 ) RATED BRAKE HORSEPOWER (bhp) is the rating specified by the manufacturer, without regard to any derating, and listed on the engine nameplate. ( 1 6 ) RICH
