A. Authorized Official. "Authorized Official" means any duly authorized person given permission by an owner/operator to conduct business with the Department on their behalf.

B. Facility. "Facility" means the aggregate of all the non-temporary pollutant-emitting activities which are located on one or more contiguous or adjacent properties and are under the control of the same person (or persons under common control).

C. Concrete Batch Pant. "Concrete Batch Plant (CBP)" means a facility manufacturing concrete from any combination of cement, cement supplement, fine aggregate, coarse aggregate and water. The CBP includes associated aggregate bins, weigh hoppers and cement storage silos.

D. Operator. "Operator" means any person has direct control or supervision over a regulated source (Concrete Batch Plant and/or power plant engine and/or boiler or hot water heater) and who has a registered agreement to operate such equipment in accordance with the conditions of this regulation. The operator may also be the owner of the equipment.

E. Owner. "Owner" means any person who legally owns a regulated source (Concrete Batch Plant, and/or power plant engine and/or boiler or hot water heater) and who receives a General Permit for that regulated source under the terms of this regulation. The owner may also be the operator of the equipment.

F. Performance Test. "Performance Test" means a certified visible emissions observation performed per EPA Method 9. The duration of the Method 9 observation shall be 30 minutes (five 6-minute averages). Compliance with the applicable fugitive emission limits shall be based on an average of the five 6-minute averages.

G. Portable Non-Road Engine. "Portable Non-Road Engine" means an internal combustion engine which is portable or transportable, meaning designed to be and capable of being carried or moved from one location to another. Indicia of transportability include, but are not limited to, wheels, skids, carrying handles, dolly, trailer, or platform. This definition does NOT include engines which remain or will remain at a location for more than 12 consecutive months or a shorter period of time for an engine located at a seasonal source. A location is any single site at a building, structure, facility, or installation. Any engine that replaces an engine at a location and that is intended to perform the same or similar function as the engine replaced will be included in calculating the consecutive time period.

An engine located at a seasonal source is an engine that remains at a seasonal source during the full annual operating period of the seasonal source. A seasonal source is a stationary source that remains in a single location on a permanent basis (i.e., at least two years) and that operates at that single location approximately three months (or more) each year.

H. Portable Plant. "Portable Plant" means any Concrete Batch Plant that is mounted on any chassis or skids and may be moved by the application of a lifting or pulling force.

I. Power Plant Engine. "Power Plant Engine" means any internal combustion engine whose function is to power a concrete batch plant including gen-sets, direct drive engines, and engines used to power hydraulic drives.

J. Safe Access. "Safe Access" means reasonable access to the regulated facility which complies with safety requirements of all local, state, or federal regulating authorities as well as the written safety standard operating procedures for that facility.

K. Stationary Plant. "Stationary Plant" means any Concrete Batch Plant that cannot meet the definition of "Portable Plant."

L. Temporary Equipment. "Temporary Equipment" means any pollutant-emitting equipment or devices which are operated at a particular site for less than four (4) consecutive weeks in a calendar year.
