The alternate control requirements for surface coating processes
in the Beaumont-Port Arthur, Bexar County, Dallas-Fort Worth, El Paso,
and Houston-Galveston-Brazoria areas and in Gregg, Nueces, and Victoria
Counties are as follows.
(1) Emission calculations for surface coating operations
performed to satisfy the conditions of §101.23 of this title
(relating to Alternate Emission Reduction ("Bubble") Policy), §115.910
of this title (relating to Availability of Alternate Means of Control),
or other demonstrations of equivalency with the specified emission
limits in this division must be based on the pounds of volatile organic
compounds (VOC) per gallon of solids for all affected coatings. The
owner or operator shall use the following equation to convert emission
limits from pounds of VOC per gallon of coating to pounds of VOC per
gallon of solids:

(2) Any alternate methods of demonstrating and documenting
continuous compliance with the applicable control requirements or
exemption criteria in this division, such as use of improved transfer
efficiency, may be approved by the executive director in accordance
with §115.910 of this title if emission reductions are demonstrated
to be substantially equivalent.
(3) If a vapor control system is used to control emissions
from coating operations:
(A) the capture and abatement system must be capable
of achieving and maintaining emission reductions equivalent to the
emission limitations of §115.421 of this title (relating to Emission
Specifications) and an overall control efficiency of at least 80%
of the VOC emissions from those coatings. The owner or operator shall
use the following equation to determine the minimum overall control
efficiency necessary to demonstrate equivalency with the emission
limitations of §115.421 of this title:

(B) the owner or operator shall submit design data
for each capture system and emission control device that is proposed
for use to the executive director for approval. In the Beaumont-Port
Arthur, Bexar County, Dallas-Fort Worth, El Paso, and Houston-Galveston-Brazoria
areas, capture efficiency testing must be performed in accordance
with §115.425(4) of this title (relating to Testing Requirements).
(4) For any surface coating process or processes at
a specific property, the executive director may approve requirements
different from those in §115.421(8) of this title based upon
his determination that such requirements will result in the lowest
emission rate that is technologically and economically reasonable.
When such a determination is made, the executive director shall specify
the date or dates by which such different requirements must be met
and shall specify any requirements to be met in the interim. If the
emissions resulting from such different requirements equal or exceed
25 tons a year for a property, the determinations for that property
must be reviewed every five years. Executive director approval does
not necessarily constitute satisfaction of all federal requirements
nor eliminate the need for approval by the United States Environmental
Protection Agency in cases where specified criteria for determining
equivalency have not been clearly identified in applicable sections
of this chapter.
