Code of Federal Regulations Title 40. Protection of Environment 40 CFR Pt. 63, Subpt. WWWW, Tbl. 3 Table 3 to Subpart WWWW of Part 63—Organic HAP Emissions Limits for Specific Open Molding, Centrifugal Casting, Pultrusion and Continuous Lamination/Casting Operations

Current as of October 02, 2022 | Updated by FindLaw Staff

As specified in § 63.5805, you must meet the following organic HAP emissions limits that apply to you:

If your operation type is . . .

And you use . . .

1 Your organic HAP emissions limit is . . .

1. open molding—corrosion-resistant and/or high strength (CR/HS)

a. mechanical resin application

113 lb/ton.

b. filament application

171 lb/ton.

c. manual resin application

123 lb/ton.

2. open molding—non-CR/HS

a. mechanical resin application

88 lb/ton.

b. filament application

188 lb/ton.

c. manual resin application

87 lb/ton.

3. open molding—tooling

a. mechanical resin application

254 lb/ton.

b. manual resin application

157 lb/ton.

4. open molding—low-flame spread/low-smoke products

a. mechanical resin application

497 lb/ton.

b. filament application

270 lb/ton.

c. manual resin application

238 lb/ton.

5. open molding—shrinkage controlled resins 2

a. mechanical resin application

354 lb/ton.

b. filament application

215 lb/ton.

c. manual resin application

180 lb/ton.

6. open molding—gel coat 3

a. tooling gel coating

440 lb/ton.

b. white/off white pigmented gel coating

267 lb/ton.

c. all other pigmented gel coating

377 lb/ton.

d. CR/HS or high performance gel coat

605 lb/ton.

e. fire retardant gel coat

854 lb/ton.

f. clear production gel coat

522 lb/ton.

7. centrifugal casting—CR/HS

a. resin application with the mold closed, and the mold is vented during spinning and cure

25 lb/ton. 4

b. resin application with the mold closed, and the mold is not vented during spinning and cure

NA—this is considered to be a closed molding operation.

c. resin application with the mold open, and the mold is vented during spinning and cure

25 lb/ton. 4

d. resin application with the mold open, and the mold is not vented during spinning and cure

Use the appropriate open molding emission limit. 5

8. centrifugal casting—non-CR/HS

a. resin application with the mold closed, and the mold is vented during spinning and cure

20 lb/ton. 4

b. resin application with the mold closed, and mold is not vented during the spinning and cure

NA—this is considered to be a closed molding operation.

c. resin application with the mold open, and the mold is vented during spinning and cure

20 lb/ton. 4

d. resin application with the mold open, and the mold is not vented during spinning and cure

Use the appropriate open molding emission limit. 5

9. pultrusion 6

N/A

reduce total organic HAP emissions by at least 60 weight percent.

10. continuous lamination/casting

N/A

reduce total organic HAP emissions by at least 58.5 weight percent or not exceed a organic HAP emissions limit of 15.7 lbs of organic HAP per ton of neat resin plus and neat gel coat plus.

1 Organic HAP emissions limits for open molding and centrifugal casting are expressed as lb/ton. You must be at or below these values based on a 12-month rolling average.

2 This emission limit applies regardless of whether the shrinkage controlled resin is used as a production resin or a tooling resin.

3 If you only apply gel coat with manual application, for compliance purposes treat the gel coat as if it were applied using atomized spray guns to determine both emission limits and emission factors. If you use multiple application methods and any portion of a specific gel coat is applied using nonatomized spray, you may use the nonatomized spray gel coat equation to calculate an emission factor for the manually applied portion of that gel coat. Otherwise, use the atomized spray gel coat application equation to calculate emission factors.

4 For compliance purposes, calculate your emission factor using only the appropriate centrifugal casting equation in item 2 of Table 1 to this subpart, or a site specific emission factor for after the mold is closed as discussed in § 63.5796.

5 Calculate your emission factor using the appropriate open molding covered cure emission factor in item 1 of Table 1 to this subpart, or a site specific emission factor as discussed in § 63.5796.

6 Pultrusion machines that produce parts that meet the following criteria: 1,000 or more reinforcements or the glass equivalent of 1,000 ends of 113 yield roving or more;  and have a cross sectional area of 60 square inches or more are not subject to this requirement. Their requirement is the work practice of air flow management which is described in Table 4 to this subpart.
