^a The limits are expressed in two sets of equivalent units:  grams per liter of coating (minus water and exempt solvent); and grams per liter of solids. Either set of limits may be used to demonstrate compliance.

^b  To convert from grams/liter to pounds/gallon, multiply by (3.785 liters/gallon)(pound/453.6 grams) or 1/120.  For compliance purposes, metric units define the standards.

^c  VOC limits expressed in units of mass of VOC per volume of solids were derived from the VOC limits expressed in units of mass of VOC per volume of coating assuming the coatings contain no water or exempt compounds and that the volumes of all components within a coating are additive.

^d These limits apply during cold-weather time periods (i.e., temperatures below 4.5 degrees Celsius (40 degrees Fahrenheit)). Cold-weather allowances are not given to coatings in categories that permit less than 40% solids nonvolatiles) content by volume. Such coatings are subject to the same limits regardless of weather conditions.


117A            (B)  For a coating to which thinning solvent is routinely or sometimes added, the owner or operator shall determine the VOC content as follows.

117A                 (i)  Prior to the first application of each batch, designate a single thinner for the coating and calculate the maximum allowable thinning ratio (or ratios, if the shipbuilding and ship repair operation complies with the cold-weather limits in addition to the other limits specified in subparagraph (A) of this paragraph) for each batch as follows:

      (V_S)(VOC limit) - m_VOC                                  
R = --------------------------------       (Equation 1)
                D_th

where:
     R  =  Maximum allowable thinning ratio for a given batch (liters of thinner per liter of coating as supplied);
     V_s  =  Volume fraction of solids in the batch as supplied (liter of solids per liter of coating as supplied);
     VOC limit  =  Maximum allowable as-applied VOC content of the coating (grams of VOC per liter of solids);
     m_VOC  =  VOC content of the batch as supplied (grams of VOC per liter of coating as supplied); and
     D_th  =  Density of the thinner (grams per liter).


117A                     (ii)  If V_s is not supplied directly by the coating manufacturer, the owner or operator shall determine V_s as follows:

          1 -  (m_volatiles)
V_s =  -------------------------       (Equation 2)
               D_avg

where:
     m_volatiles  =  Total volatiles in the batch, including VOC, water, and exempt compounds (grams per liter of coating); and
     D_avg  =  Average density of volatiles in the batch (grams per liter).


117A  (b)  No person in Gregg, Nueces, and Victoria Counties may cause, suffer, allow, or permit VOC emissions from the surface coating processes affected by paragraphs (1)-(9) of this subsection to exceed the specified emission limits.  These limitations are based on the daily weighted average of all coatings delivered to each coating line, except for those in paragraph (9) of this subsection which are based on paneling surface area.  For the purposes of this division (relating to Surface Coating Processes), daily weighted average means the total weight of VOC emissions from all coatings, divided by the total volume of all coatings (minus water and exempt solvent) delivered to the application system each day.

105K       (1)  Large appliance coating.  VOC emissions from the application, flashoff, and oven areas during the coating of large appliances (prime and topcoat, or single coat) shall not exceed 2.8 pounds per gallon of coating (minus water and exempt solvent) delivered to the application system (0.34 kg/liter).

105K       (2)  Metal furniture coating.  VOC emissions from metal furniture coating lines (prime and topcoat, or single coat) shall not exceed 3.0 pounds per gallon of coating (minus water and exempt solvent) delivered to the application system (0.36 kg/liter).

105K       (3)  Coil coating.  VOC emissions from the coating (prime and topcoat, or single coat) of metal coils shall not exceed 2.6 pounds per gallon of coating (minus water and exempt solvent) delivered to the application system (0.31 kg/liter).

105K       (4)  Paper coating.  VOC emissions from the coating of paper (or specified tapes or films) shall not exceed 2.9 pounds per gallon of coating (minus water and exempt solvent) delivered to the application system (0.35 kg/liter).

117A  (a)  For all affected persons in the Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston areas, the following alternate control requirements may apply.

117A       (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 (relating to Surface Coating Processes) shall be based on the pounds of volatile organic compounds (VOC) per gallon of solids for all affected coatings.  The following equation shall be used to convert emission limits from pounds of VOC per gallon of coating to pounds of VOC per gallon of solids:

S = C / (1 - (C / D))

where:
     S = the applicable emission limit from §115.421(a) of this title (relating to Emission Specifications) expressed on a pounds of VOC per gallon of solids basis
     C = the applicable emission limit from §115.421(a) of this title expressed on a pounds of VOC per gallon of coating basis
     D = an assumed solvent density of 7.36 pounds of VOC per gallon

117A       (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.

88C        (3)  If a vapor recovery system is used to control emissions from coating operations, the capture and abatement system shall be capable of achieving and maintaining emission reductions equivalent to the emission limitations of §115.421(a) 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 of any surface coating facility shall submit design data for each capture system and emission control device which is proposed for use to the Executive Director for approval.  Any capture efficiency testing shall be performed in accordance with §115.425(a)(4) of this title (relating to Testing Requirements).

88C        (4)  For any surface coating process or processes at a specific property, the Executive Director may approve requirements different from those in §115.421(a)(9) of this title based upon his determination that such requirements will result in the lowest emission rate that is technologically and economically reasonable.  When he makes such a determination, the Executive Director shall specify the date or dates by which such different requirements shall 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 shall be reviewed every two 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 (EPA) in cases where specified criteria for determining equivalency have not been clearly identified in applicable sections of this chapter.

117A  (b)  For all affected persons in Gregg, Nueces, and Victoria Counties, the following alternate control requirements may apply:

117A       (1)  Emission calculations for surface coating operations performed to satisfy the conditions of §101.23 of this title, §115.910 of this title, or other demonstrations of equivalency with the specified emission limits in this division (relating to Surface Coating Processes) shall be based on the pounds of VOC per gallon of solids for all affected coatings.  The following equation shall be used to convert emission limits from pounds of VOC per gallon of coating to pounds of VOC per gallon of solids:

S = C / (1 - (C / D))

where:
     S = the applicable emission limit from §115.421(b) of this title expressed on a pounds of VOC per gallon of solids basis
     C = the applicable emission limit from §115.421(b) of this title expressed on a pounds of VOC per gallon of coating basis
     D = an assumed solvent density of 7.36 pounds of VOC per gallon

117A       (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.

88C        (3)  If a vapor recovery system is used to control emissions from coating operations, the capture and abatement system shall be capable of achieving and maintaining emission reductions equivalent to the emission limitations of §115.421(b) of this title and an overall control efficiency of at least 80% of the VOC emissions from those coatings.  The owner or operator of any surface coating facility shall submit design data for each capture system and emission control device which is proposed for use to the executive director for approval.

105K       (4)  For any surface coating process or processes at a specific property the executive director may approve requirements different from those in §115.421(b)(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 he makes such a determination, the executive director shall specify the date or dates by which such different requirements shall 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 shall be reviewed every two years.  Executive Director approval does not necessarily constitute satisfaction of all federal requirements nor eliminate the need for approval by the EPA in cases where specified criteria for determining equivalency have not been clearly identified in applicable sections of this chapter.

§115.425.  Testing Requirements.

88C   (a)  For the Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston areas, the following testing requirements shall apply:

88C        (1)  Compliance with §115.421(a) of this title (concerning Emission Specifications) shall be determined by applying the following test methods, as appropriate:

88C             (A)  Test Method 24 (40 Code of Federal Regulations (CFR) 60, Appendix A) with a one-hour bake;

88C        (3)  Compliance with the alternative emission limits in §115.421(a)(8)(A) of this title shall be determined by applying the following test methods, as appropriate:

74A             (A)  Protocol for Determining the Daily VOC Emission Rate of Automobile and Light-Duty Truck Topcoat Operations (EPA 450/3-88-018); or

88C             (B)  The procedure contained in this paragraph for determining daily compliance with the alternative emission limitation in §115.421(a)(8)(A) of this title for final repair. Calculation of occurrence weighted average for each combination of repair coatings (primer, specific basecoat, clearcoat) shall be determined by the following procedure.

77C                  (i)  The characteristics identified below, which are represented in the following equations by the variables shown, are established for each repair material as sprayed:

77C

-
Primer
Basecoat
Clearcoat
VOC (lb/gal) -
Vp
Vb

77D         (4)  The capture efficiency shall be measured using applicable procedures outlined in 40 CFR Part 52.741, Subpart O, Appendix B.  These procedures are:

Procedure T - Criteria for and Verification of a Permanent or Temporary Total Enclosure

Procedure L - VOC Input

Procedure G.2 - Captured VOC Emissions (Dilution Technique)

Procedure F.1 - Fugitive VOC Emissions from Temporary Enclosures

Procedure F.2 - Fugitive VOC Emissions from Building Enclosures


77D             (A)  Exemptions to capture efficiency testing requirements:

77D                  (i)  If a source installs a permanent total enclosure (PTE) which meets the specifications of Procedure T and which directs all VOC to a control device, then the capture efficiency is assumed to be 100%, and the source is exempted from capture efficiency testing requirements.  This does not exempt the source from performance of any control device efficiency testing that may be required.  In addition, a source must demonstrate all criteria for a PTE are met during testing for control efficiency.

77D                  (ii)  If a source uses a control device designed to collect and recover VOC (e.g., carbon adsorber), an explicit measurement of capture efficiency is not necessary if the following conditions are met.  The overall control of the system can be determined by directly comparing the input liquid VOC to the recovered liquid VOC.  The general procedure for use in this situation is given in 40 CFR 60.433 with the following additional restrictions:

77D                       (I)  the source must be able to equate solvent usage with solvent recovery on a 24-hour (daily) basis, rather than a 30-day weighted average.  This must be done within 72 hours following each 24-hour period, and

77D                       (II)  the solvent recovery system (i.e., capture and control system) must be dedicated to a single process line (e.g., one process line venting to a carbon adsorber system); or if the solvent recovery system controls multiple process lines, the source must be able to demonstrate that the overall control (i.e., the total recovered solvent VOC divided by the sum of liquid VOC input to all process lines venting to the control system) meets or exceeds the most stringent standard applicable for any process line venting to the control system.

77D             (B)  The capture efficiency shall be calculated using one of the following four protocols referenced.  Any affected source must use one of these protocols, unless a suitable alternative protocol is approved by the executive director and EPA.

77D                  (i)  Gas/gas method using Temporary Total Enclosure (TTE).  EPA specifications to determine whether a temporary enclosure is considered a TTE are given in Procedure T.  The capture efficiency equation to be used for this protocol is:

CE = Gw / (Gw + Fw)

Where:
     CE = capture efficiency, decimal fraction
     Gw = mass of VOC captured and delivered to control device using a TTE (use Procedure G.2)
     Fw =  mass of fugitive VOC that escapes from a TTE (use Procedure F.1)

77D                  (ii)  Liquid/gas method using TTE.  EPA specifications to determine whether a temporary enclosure is considered a TTE are given in Procedure T.  The capture efficiency equation to be used for this protocol is:

CE = (L - F) / L

Where:
     CE = capture efficiency, decimal fraction
     L  =  mass of liquid VOC input to process (use Procedure L)
     F  =  mass of fugitive VOC that escapes from a TTE (use Procedure F.1)

77D                  (iii)  Gas/gas method using the building or room in which the affected source is located as the enclosure (BE) and in which G and F are measured while operating only the affected facility.  All fans and blowers in the BE must be operating as they would under normal production.  The capture efficiency equation to be used for this protocol is:

CE = G / (G + Fb)

Where:
     CE = capture efficiency, decimal fraction
     G = mass of VOC captured and delivered to a control device (use Procedure G.2)
     Fb = mass of fugitive VOC that escapes from building enclosure (use Procedure F.2)

77D                  (iv)  Liquid/gas method using a BE in which L and F are measured while operating only the affected facility.  All fans and blowers in the building or room must be operated as they would under normal production.  The capture efficiency equation to be used for this protocol is:

CE = (L - Fb) / L

Where:
     CE = capture efficiency, decimal fraction
     L = mass of liquid VOC input to process (use Procedure L)
     Fb = mass of fugitive VOC that escapes from BE (use Procedure F.2)

77D             (C)  The following conditions must be met in measuring capture efficiency:

77D                  (i)  Any error margin associated with a test protocol may not be incorporated into the results of a capture efficiency test.

88F                  (ii)  All affected facilities shall accomplish the initial capture efficiency testing by July 31, 1992 in Brazoria, Dallas, El Paso, Galveston, Harris, Jefferson, Orange, and Tarrant Counties, and by July 31, 1993 in Chambers, Collin, Denton, Fort Bend, Hardin, Liberty, Montgomery, and Waller Counties, except that all mirror backing coating facilities shall accomplish the initial capture efficiency testing by July 31, 1994.

77D                  (iii)  During an initial pretest meeting, the Texas Natural Resource Conservation Commission (TNRCC) and the source owner or operator shall identify those operating parameters which shall be monitored to ensure that capture efficiency does not change significantly over time.  These parameters shall be monitored and recorded initially during the capture efficiency testing and thereafter during facility operation.  The TNRCC may require a new capture efficiency test if the operating parameter values change significantly from those recorded during the initial capture efficiency test.
