(B) all existing and proposed engine and turbine exhausts are
released to the atmosphere at a height at least twice the height of any surrounding
obstructions to wind flow. Buildings, open-sided roofs, tanks, separators,
heaters, covers, and any other type of structure are considered as obstructions
to wind flow if the distance from the nearest point on the obstruction to
the nearest exhaust stack is less than five times the lesser of the height,
Hb, and the width, Wb, where:

(C) the total emissions of NOx
(nitrogen oxide plus NO2) from all existing and
proposed facilities on the property do not exceed the most restrictive of
the following:
(i) 250 tpy;
(ii) the value (0.3125 D) tpy, where D equals the shortest
distance in feet from any existing or proposed stack to the nearest property
line.
(7) Upon issuance of a standard permit for electric generating
units, registrations under this section for engines or turbines used to generate
electricity will no longer be accepted, except for:
(A) engines or turbines used to provide power for the operation

Batch Plants;
(B) engines or turbines satisfying the conditions for facilities
permitted by rule under Subchapter E of this title (relating to Aggregate
