   (C) Pumps;

   (D) Compressors;

   (E) Pile drivers;

   (F) Welding;

   (G) Cranes; and

   (H) Wood chippers.

4. Sand and gravel screening, rock crushing, and unheated pavement crushing and recycling operations
5. Unconfined abrasive blasting

(c) Definitions
For the purpose of this rule, the following definitions apply:

1. ADMINISTERING DISTRICT is a district that adopts equivalent provisions to those contained in subdivisions (c), (d), (e), (f), (g), (h), (i), (j), and (k) of this rule for one or more of the equipment categories listed in subdivision (b) of this rule, and the participating district at which the owner or operator of a portable emissions unit files an application for registration. A district can be an administering district only for the equipment categories for which it has adopted the requirements contained in this rule.
2. AQMD means South Coast Air Quality Management District.
3. DISTRICT is an air pollution control district or air quality management district duly organized under the applicable provisions of California Health and Safety Code.
4. DUST-TIGHT means free from visible airborne dust.
5. EMISSIONS UNIT is an identifiable process, operation, or piece of process equipment such as an article, machine, or other contrivance, which emits or may emit, or results in the emissions of any air contaminant directly or as fugitive emissions. For the purpose of this rule, each internal combustion engine constitutes a separate emissions unit.
6. EXEMPT COMPOUNDS are defined in AQMD Rule 102 -- Definition of Terms.
7. FACILITY means any one or more contiguous or adjacent properties. Contiguous or adjacent properties are properties with two or more parcels of land in actual physical contact, separated solely by a public roadway or other public right-of-way under the same or common ownership or control.
8. FUGITIVE DUST means any solid particulate matter that becomes airborne, other than that emitted from an exhaust stack, directly or indirectly as a result of the activities of man.
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 emissions unit. For emissions units which are brought to a facility to perform maintenance on equipment at its permanent or ordinary location, each maintenance site shall be a separate location.
10. NONROAD ENGINE is a portable engine that requires a permit and is certified by the Executive Officer to be a nonroad engine as defined by U. S. EPA pursuant to 40 CFR Part 89.
11. PARTICIPATING DISTRICT is any district that, through rulemaking, agrees to give effect and enforce registrations issued by an administering district. A participating district may choose to recognize registrations for one or more of the equipment categories listed in subdivision (b).
12. PORTABLE EMISSIONS UNIT is any emissions unit 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, platform or mounting. The owner or operator must demonstrate the necessity of the unit being periodically moved from one location to another because of the nature of the operation.

    An emissions unit is not portable if:

    (A) the emissions unit or its replacement remains or will reside at the same location for more than 12 consecutive months. Any emissions unit, such as a back-up or stand-by unit, that replaces an emissions unit at a location and is intended to perform the same function as the unit being replaced, will be included in calculating the consecutive time period. In that case, the cumulative time of both emissions units, including the time between the removal of the original unit and installation of the replacement unit, would be counted toward the consecutive time period; or

    (B) the emissions unit remains 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 emissions unit is removed from one location for a period and then it or its equivalent is returned to the same location in an attempt to circumvent the portable emissions unit residence time requirements.

    The period during which the emissions unit is maintained at a storage facility shall be excluded from the residency time determination.

13. Project means one or more registered portable emissions unit(s) operated at a facility under the same or common ownership or control, and used to perform a single activity.
14. VOLATILE ORGANIC COMPOUND (VOC) is any volatile compound of carbon, excluding methane, carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, ammonium carbonate and exempt compounds.

(d) Registration Process:

1. The owner or operator of a portable emissions unit may elect to register the unit pursuant to the provisions of this rule or permit it pursuant to AQMD Regulation II - Permits.
2. Upon registration in accordance with the provisions of this subdivision the following existing AQMD rule provisions will no longer apply to the portable emissions unit: Regulation II - Permits (with the exception of Rules 206, 207, 209, 214, 216, and 217), Regulation IV - Prohibitions, Regulation XI - Source Specific Standards (with the exception of Rule 1110.2 on or after December 31, 1999), Regulation XIII - New Source Review, and Regulation XIV - Toxics and Other Non-Criteria Pollutants.
