WHAT THE SUBPART COVERS


63.5680 What is the purpose of this subpart?

(a) This subpart establishes national emission standards for hazardous air pollutants (HAP) for new and existing boat manufacturing facilities with resin and gel coat operations, carpet and fabric adhesive operations, or aluminum boat surface coating operations. This subpart also establishes requirements to demonstrate initial and continuous compliance with the emission standards.

63.5683 Does this subpart apply to me?

(a) This subpart applies to you if you meet both of the criteria listed in paragraphs (a)(1) and (2) of this section.

(1) You are the owner or operator of a boat manufacturing facility that builds fiberglass boats or aluminum boats.

(2) Your boat manufacturing facility is a major source of HAP either in and of itself, or because it is collocated with other sources of HAP, such that all sources combined constitute a major source.

(b) A boat manufacturing facility is a facility that manufactures hulls or decks of boats from fiberglass or aluminum, or assembles boats from premanufactured hulls and decks, or builds molds to make fiberglass hulls or decks. A facility that manufactures only parts of boats (such as hatches, seats, or lockers) or boat trailers is not considered a boat manufacturing facility for the purpose of this subpart.

(c) A major source is any stationary source or group of stationary sources located within a contiguous area and under common control that emits or can potentially emit, considering controls, in the aggregate, 9.1 megagrams (10 tons) or more per year of a single HAP or 22.7 megagrams (25 tons) or more per year of a combination of HAP.

(d) This subpart does not apply to aluminum coating operations on aluminum boats intended for commercial or military use, antifoulant coatings, fiberglass assembly adhesives, fiberglass hull and deck coatings, mold sealing and release agents, mold stripping and cleaning solvents, and wood coatings as defined in 63.5779. This subpart does not apply to materials contained in handheld aerosol cans.

63.5686 How do I demonstrate that my facility is not a major source?

(a) To demonstrate that your facility is not a major source based on emissions, you must demonstrate that your facility does not emit, and does not have the potential to emit, considering federally enforceable permit limits, 9.1 megagrams (10 tons) or more per year of a single HAP or 22.7 megagrams (25 tons) or more per year of a combination of HAP. To calculate your facility’s potential to emit, you must include emissions from the boat manufacturing facility and all other sources that are collocated and under common ownership or control with the boat manufacturing facility.

(b) To demonstrate that you are not a major source based on material consumption, you must: manufacture either fiberglass or aluminum boats at your facility, but not both; demonstrate that you are not collocated with another source of HAP; and meet the requirement in paragraph (b)(1) or (2) of this section.

(1) If your facility is a fiberglass boat manufacturing facility, you must demonstrate that it consumes less than 45.4 megagrams (50 tons) per year of all polyester- and vinylester-based resins and gel coats, including tooling and production resins and gel coats, and clear gel coats.

(2) If your facility is an aluminum boat manufacturing facility, you must demonstrate that it consumes less than 18.2 megagrams (20 tons) per year of all carpet and fabric adhesives, surface wipe-down and application gun cleaning solvents, and paints and coatings.

63.5689 What parts of my facility are covered by this subpart?

The affected source (the portion of your boat manufacturing facility covered by this subpart) is the combination of all of the boat manufacturing operations listed in paragraphs (a) through (f) of this section.

(a) Open molding resin and gel coat operations (including pigmented gel coat, clear gel coat, production resin, tooling gel coat, and tooling resin).

(b) Closed molding resin operations.

(c) Resin and gel coat mixing operations.

(d) Resin and gel coat application equipment cleaning operations.

(e) Carpet and fabric adhesive operations.

(f) Aluminum hull and deck coating operations, including solvent wipe-down operations and paint spray gun cleaning operations, on aluminum boats.

63.5692 How do I know if my boat manufacturing facility is a new affected source or an existing affected source?

(a) A boat manufacturing facility is a new affected source if it meets the criteria in paragraphs (a)(1) through (3) of this section.

(1) You commence construction of the affected source after [INSERT DATE OF PUBLICATION OF THIS PROPOSAL IN THE FEDERAL REGISTER].

(2) It is a major source.

(3) It is a completely new boat manufacturing affected source where no other boat manufacturing affected source existed prior to the construction of the new affected source.

(b) For the purposes of this subpart, an existing affected source is any affected source that is not a new affected source.

63.5695 When must I comply with this subpart?

You must comply with the standards in this subpart by the dates specified in table 1 to this subpart.

63.5710 How do I demonstrate compliance using MACT model point value averaging?


(a) Compliance using the MACT model point value averaging option is demonstrated on a 3-month rolling- average basis and is determined at the end of every month (12 times per year).

(b) At the end of every month, use equation 2 to demonstrate that the HAP emissions from those operations included in the average do not exceed the emission standard in 63.5698. (Include terms in equation 1 in 63.5698 and equation 2 for only those operations and materials included in the average.)

HAP emissions = [(PVR)(MR) + (PVPG)(MPG) + (PVCG)(MCG) + (PVTR)(MTR) + (PVTG)(MTG)]

Where:

HAP emissions =
HAP emissions calculated using MACT model point values for each operation included in the average, kilograms.
PVR =
Weighted-average MACT model point value for production resin used in the past 3 months, kilograms per megagram.
MR =
Mass of production resin used in the past 3 months, megagrams.

(c) At the end of every month, use equation 3 to compute the weighted-average MACT model point value for each open molding resin and gel coat operation included in the average.

Where:

PVOP =
weighted-avg MACT model point value for each open molding operation (PVR, PVPG, PVCG, PVTR, and PVTG) included in the average, kgs. of HAP per megagram of material applied.
Mi =
mass of resin or gel coat i used within an operation in the past 3 months, megagrams.
n =
number of different open molding resins or gel coats used within an operation in the past 3 months.
PVi =
the MACT model point value for resin or gel coat i used within an operation in the past 3 months, kgs. of HAP per megagram of material applied.

(d) You must use the equations in table 3 to this subpart to calculate the MACT model point value (PVi) for each resin and gel coat used in each operation in the past 3 months.

(e) If the HAP emissions, as calculated in paragraph (b) of this section, are less than the HAP limit calculated in 63.5698(b), then you are in compliance with the emission standard in 63.5698 for those operations and materials included in the average.

63.5713 How do I demonstrate compliance using compliant materials?

(a) Compliance using the HAP content requirements listed in table 2 to this subpart is based on a 3-month rolling average that is calculated at the end of every month.

(b) At the end of every month, review the HAP contents of the resins and gel coats used in the past 3 months in each operation. If all resins and gel coats used in an operation have HAP contents no greater than the applicable HAP content requirements in table 2 to this subpart, then you are in compliance with the emission standard specified in 63.5698 for that 3-month period for that operation. In addition, you do not need to complete the weighted-average HAP content calculation contained in paragraph (c) of this section for that operation.

(c) At the end of every month, you must use equation 4 to calculate the weighted-average HAP content for all resins and gel coats used in that operation in the past 3 months.

Where:

Mi = mass of open molding resin or gel coat i used in the past 3 months in an operation, megagrams.
HAPi = HAP content, by weight percent, of open molding resin or gel coat i used in the past 3 months in an operation. Use the methods in 63.5758 to determine HAP content.
n = number of different open molding resins or gel coats used in the past 3 months in an operation.

(d) If the weighted-average HAP content does not exceed the applicable HAP content requirement specified in table 2 to this subpart, then you are in compliance with the emission standard specified in 63.5698.




DEMONSTRATING COMPLIANCE FOR OPEN MOLDING OPERATIONS CONTROLLED BY ADD-ON CONTROL DEVICES


63.5716 When must I conduct a performance test?

(a) You must conduct an initial control device performance test within 180 calendar days after the compliance date specified in 63.5695 and according to the provisions in 63.7(a)(2).

(b) If you commenced construction between today’s date and the effective date of the subpart, you must demonstrate initial compliance with either the proposed emission standard or the promulgated emission standard no later than 180 calendar days after the effective date of the regulation or within 180 calendar days after startup of the source, whichever is later, according to 63.7(a)(2)(ix).

(c) If you commenced construction between today’s date and the effective date of the subpart, and you chose to comply with the proposed emission standard when demonstrating initial compliance, you must conduct a second compliance demonstration for the promulgated emission standard within 3 years and 180 calendar days after the effective date of the subpart, or after startup of the source, whichever is later, according to 63.7(a)(2)(ix).

(d) You must conduct a performance test every 5 years as part of renewing your 40 CFR part 70 or part 71 operating permit.

63.5719 How do I conduct a performance test?

(a) You must capture the emissions using a permanent enclosure (such as a spray booth or similar containment device) and direct the captured emissions to the add-on control device.

(b) You must measure emissions as specified in paragraph (b)(1) or (2) of this section.

    (1) If the enclosure vented to the control device is a permanent total enclosure as defined in Method 204 of appendix M to 40 CFR part 51, then you may measure emissions only at the outlet of the control device.

    (2) If the permanent enclosure vented to the control device is not a total enclosure, you must build a temporary total enclosure, as defined in Method 204 of appendix M to 40 CFR part 51, around the permanent enclosure. You must then simultaneously measure emissions from the control device outlet and the emissions from the total temporary enclosure outlet. You determine compliance from the combined emissions from the control device outlet and the total temporary enclosure outlet.

(c) You must conduct the control device performance test using the emission measurement methods specified in paragraphs (c)(1) through (3) of this section.

    (1) Use either Method 1 or 1A of appendix A to 40 CFR part 60, as appropriate, to select the sampling sites.

    (2) Use Method 2, 2A, 2C, 2D, 2F or 2G of appendix A to 40 CFR part 60, as appropriate, to measure gas volumetric flow rate.

    (3) Use Method 18 of appendix A to 40 CFR part 60 to measure HAP emissions or use Method 25A of appendix A to 40 CFR part 60 to measure total gaseous organic emissions as a surrogate for total HAP emissions. If you use Method 25A, you must assume that all gaseous organic emissions measured as carbon are HAP emissions. If you use Method 18 and the number of HAP in the exhaust stream exceeds five, you must take into account the use of multiple chromatographic columns and analytical techniques to get an accurate measure of at least 90 percent of the total HAP mass emissions. Do not use Method 18 to measure HAP emissions from a combustion device; use instead Method 25A and assume that all gaseous organic mass emissions measured as carbon are HAP emissions.

(d) The control device performance test must consist of three runs and each run must last at least 1 hour. The production conditions during the test runs must represent normal production conditions with respect to the types of parts being made and material application methods. The production conditions during the test must also represent maximum potential emissions with respect to the HAP content of the materials being applied and the material application rates.

(e) During the test, you must also monitor and record separately the amounts of production resin, tooling resin, pigmented gel coat, clear gel coat, and tooling gel coat applied inside the enclosure that is vented to the control device.

63.5722 How do I use the performance test data to demonstrate initial compliance?

Demonstrate initial compliance with the open molding emission standard as described in paragraphs (a) through (c) of this section:

(a) Calculate the HAP limit you must achieve using equation 1 in 63.5698. For determining initial compliance, the HAP limit is based on the amount of material used during the performance test, in megagrams, rather than during the past 3 months. Calculate the limit using the megagrams of resin and gel coat applied inside the enclosure during the three runs of the performance test and equation 1 in 63.5698.

(b) Add the total measured emissions, in kilograms, from all three of the 1-hour runs of the performance test.

(c) If the total emissions from the three 1-hour runs of the performance test are less than the HAP limit calculated in paragraph (a) of this section, then you have demonstrated initial compliance with the emission standard in 63.5698 for those operations performed in the enclosure and controlled by the add-on control device.

63.5725 What are the requirements for monitoring and demonstrating continuous compliance?

(a) You must establish control device parameters that indicate proper operation of the control device.

(b) You must install, operate, and maintain a continuous parameter monitoring system as specified in paragraphs (b)(1) through (6) of this section.

(1) The continuous parameter monitoring system must complete a minimum of one cycle of operation for each successive 15-minute period. You must have a minimum of four successive cycles of operation to have a valid hour of data.

(2) You must have valid data from at least 90 percent of the hours during which the process operated.

(3) You must determine the hourly average of all recorded readings.

(4) You must determine the daily average of all recorded readings for each operating day.

(5) You must determine the 30-day average for each 30-day period.

(6) You must record the results of each inspection, calibration, and validation check.

(c) Enclosure bypass line. You must meet the requirements of paragraph (c)(1) and either paragraph (c)(2) or (3) of this section for each enclosure ventilation system that contains bypass lines that could divert emissions from a control device.

(1) If the bypass lines are opened, you must include a description of the bypass and its duration in the compliance reports required in 63.5764(c).

(2) You must properly install, operate, and maintain a flow measurement device that records the presence of a gas stream flow in each bypass line. You must meet the requirements in paragraph (b) and paragraphs (c)(2)(i) through (v) of this section for each flow measurement device.

(i) Locate the flow sensor and other necessary equipment such as straightening vanes in a position that provides a representative flow.

(ii) Use a flow sensor with a minimum tolerance of 2 percent of the flow rate.

(iii) Reduce swirling flow or abnormal velocity distributions due to upstream and downstream disturbances.

(iv) Conduct a flow sensor calibration check at least semi-annually.

(v) At least monthly, inspect all components for integrity, all electrical connections for continuity, and all mechanical connections for leakage.

(3) You must secure the bypass line in a nondiverting position with a seal in such a way that the valve or closure mechanism cannot be opened without breaking the seal. You must inspect the seal at least once per month and record the results of the inspection.

(d) Thermal oxidizers. If you are using a thermal oxidizer or incinerator as an add-on control device, you must comply with the requirements in paragraphs (d)(1) through (6) of this section.

(1) You must install a combustion temperature monitoring device in the firebox of the thermal oxidizer or incinerator, or in the duct immediately downstream of the firebox before any substantial heat exchange occurs. You must meet the requirements in paragraph (b) and paragraphs (d)(1)(i) through (vii) of this section for each temperature monitoring device.

(i) Locate the temperature sensor in a position that provides a representative temperature.

(ii) Use a temperature sensor with a minimum tolerance of 2.2o C or 0.75 percent of the temperature value, whichever is larger.

(iii) Shield the temperature sensor system from electromagnetic interference and chemical contaminants.

(iv) If a chart recorder is used, it must have a sensitivity in the minor division of at least 20o F.

(v) Perform an electronic calibration at least semiannually according to the procedures in the manufacturer’s owners manual. Following the electronic calibration, you must conduct a temperature sensor validation check in which a second or redundant temperature sensor placed nearby the process temperature sensor must yield a reading within 16.7o C of the process temperature sensor’s reading.

(vi) Conduct calibration and validation checks any time the sensor exceeds the manufacturer’s specified maximum operating temperature range or install a new temperature sensor.

(vii) At least monthly, inspect all components for integrity and all electrical connections for continuity, oxidation, and galvanic corrosion.

(2) Before or during the performance test, you must conduct a performance evaluation of the combustion temperature monitoring system according to 63.8(e). Section 63.8(e) specifies the general requirements for continuous monitoring systems and requirements for notifications, the site-specific performance evaluation plan, conduct of the performance evaluation, and reporting of performance evaluation results.

(3) During the performance test required by 63.5716, you must monitor and record the combustion temperature and determine the average combustion temperature for the three 1-hour test runs.

(4) Following the performance test, you must continuously monitor the combustion temperature and record the average combustion temperature no less frequently than every 15 minutes.

(5) You must operate the incinerator or thermal oxidizer so that the average combustion temperature in any 3-hour period does not fall below the average combustion temperature recorded during the performance test.

(6) If the average combustion temperature in any 3-hour period falls below the average combustion temperature recorded during the performance test, or if you fail to collect the minimum data specified in paragraph (d)(4) of this section, it is a deviation.

(e) Absorbers, condensers, and carbon adsorbers. If you are using an absorber, condenser, or carbon adsorber as an add-on control device, you must comply with the operating, testing, and monitoring requirements in 63.990.

(f) Other control devices. If you are using a control device other than those listed in paragraphs (d) and (e) of this section, then you must comply with the operating, testing, and monitoring requirements in 63.995.




STANDARDS FOR CLOSED MOLDING RESIN OPERATIONS


63.5728 What standards must I meet for closed molding resin operations?

(a) If a resin application operation meets the definition of closed molding specified in 63.5779, there is no requirement to reduce emissions from that operation.

63.5749 How do I calculate the HAP content of aluminum wipe-down solvents?

(a) Use equation 5 to calculate the weighted-average HAP content of aluminum wipe-down solvents used in the past 3 months.

Where:

HAPWD = weighted-average HAP content of aluminum wipe-down solvents, kilograms of HAP per liter of solids from aluminum primers and clear coats applied to bare aluminum.
n = number of different wipe-down solvents used in the past 3 months.
VolWDi = volume of aluminum wipe-down solvent i used in the past 3 months, liters.
DWDi = density of aluminum wipe-down solvent i, kilograms per liter.
WWDi = mass fraction of HAP in aluminum wipe-down solvent i.
m = number of different aluminum primers and clear coats used in the past 3 months that were applied to bare aluminum.
VolPj = volume of aluminum primer or clear coat j used in the past 3 months, liters.
SolidsPj = solids content of aluminum primer or clear coat j, liter solids per liter of coating.

(b) Compliance is based on a 3-month rolling average. If the weighted-average HAP content does not exceed 2.57 kilograms of HAP per liter of solids (21.5 pounds of HAP per gallon solids), then you are in compliance with the emission standard specified in 63.5743(a).

63.5752 How do I calculate the HAP content of aluminum boat surface coatings?

(a) Use equation 6 to calculate the weighted-average HAP content for all aluminum surface coatings used in the past 3 months.

Where:

HAPSC = weighted-average HAP content for all aluminum coating materials, kilograms of HAP per liter of coating solids.
m = number of different coatings used in the past 3 months.
VolCi = total volume of coating i used in the past 3 months, liters.
DCi = density of coating i, kilograms per liter.
WCi = mass fraction of HAP in coating i, kilograms of HAP per kilogram of coating.
n = number of different thinners and activators used in the past 3 months.
VolTj =  

total volume of thinner or activator j used in the past 3 months, liters.

DTj = density of thinner or activator j, kilograms per liter.
WTj = mass fraction of HAP in thinner or activator j, kilograms of HAP per kilogram of thinner or activator.
VSi = volume fraction of solids in coating i, liter solids per liter coating, from coating manufacturer’s formulation.

(b) Compliance is based on a 3-month rolling average. If the weighted-average HAP content does not exceed 1.22 kilograms of HAP per liter of coating solids (10.2 pound per gallon), then you are in compliance with the emission standard specified in 63.5743(b).

63.5755 How do I demonstrate compliance with the aluminum boat surface coating spray gun cleaning standards?

You must demonstrate compliance with the aluminum coating spray gun cleaning work practice standards by meeting the requirements of paragraph (a) or (b) of this section.

    (3) Keep records of the monthly inspections and any repairs that are made to the enclosed gun cleaners or the covers.




METHODS FOR DETERMINING HAZARDOUS AIR POLLUTANT CONTENT


63.5758 How do I determine the HAP content of materials?

(a) To determine the HAP content of the materials used in your open molding resin and gel coat operations, carpet and fabric adhesive operations, or aluminum boat surface coating operations, use EPA Method 311 of appendix A to 40 CFR part 63. You may use EPA Method 311, an alternative method as provided in paragraph (b) of this section, or any other reasonable means for determining the HAP content. Other reasonable means of determining HAP content include, but are not limited to, a material safety data sheet (MSDS) or a manufacturer’s hazardous air pollutant data sheet as defined in 63.5779. You are not required to test the materials that you use, but the Administrator may require a test using EPA Method 311 (or an approved alternative method) to confirm the reported HAP content. If the results of an analysis by EPA Method 311 are different from the HAP content determined by another means, the EPA Method 311 results will govern compliance determinations, except as provided in paragraph (b) of this section.

(b) You may use an alternative to EPA Method 311 for determining HAP content if that method has been approved by the Administrator according to section 63.7(f). The Administrator will approve alternative methods on a case-by-case basis.

(c) Samples used for measuring HAP content by EPA Method 311 or an approved alternative method must be collected according to the guidelines in "Standard Procedures for Collection of Coating and Ink Samples for VOC Content Analysis by Reference Method 24 and Reference Method 24A," EPA Publication No. EPA-340/1-91-010.

Table 2 to Subpart VVVV - Alternative HAP Content Requirements for Open Molding Resin and Gel Coat Operations

For this operation And this application method You must not exceed this weighted-average HAP content (weight percent) requirement:
1. Production resin operations Atomized (spray) 28 percent
2. Production resin operations Nonatomized (nonspray) 35 percent
3. Pigmented gel coat operations Any method 33 percent
4. Clear gel coat operations Any method 48 percent
5. Tooling resin operations Atomized (spray) 30 percent
6. Tooling resin operations Nonatomized (nonspray) 39 percent
7. Tooling gel coat operations Any method 40 percent

Table 3 to Subpart VVVV - MACT Model Point Value Equations for Open Molding Operations

For this operation... and this application method... Use this formula to calculate the MACT model plant value for each resin and gel coat
Atomized 0.014 x (Resin HAP%)2.425  
Atomized, plus vacuum bagging with roll-out 0.01185 x (Resin HAP%)2.425  
Atomized, plus vacuum bagging without roll-out 0.00945 x (Resin HAP%)2.425  
Nonatomized 0.014 x (Resin HAP%)2.275  
Nonatomized, plus vacuum bagging with roll-out 0.0110 x (Resin HAP%)2.275  
Nonatomized, plus vacuum bagging without roll-out 0.0076 x (Resin HAP%)2.275  
2. Pigmented gel coat, clear gel coat, tooling gel coat All methods 0.445 x (Gel coat HAP%)1.675

Equations calculate MACT model point value in kilograms of HAP per megagrams of resin or gel coat applied. The equations for vacuum bagging with roll-out are applicable when a facility rolls out the applied resin and fabric prior to applying the vacuum bagging materials. The equations for vacuum bagging without roll-out are applicable when a facility applies the vacuum bagging materials immediately after resin application without rolling out the resin and fabric. HAP% = HAP content expressed as a weight-percent value between 0 and 100%.
