N.H. Code Admin. R. Env-A 1212.06 – VOC Limits for Miscellaneous Plastic Parts and Products Coating

(a) Except as specified in (b), below, the owner or operator of a miscellaneous plastic parts and products coating operation shall control VOC emissions by one of the following control options, provided that if a specific coating is subject to more than one emission limit, the least stringent emission limit shall apply:
1. (1) Control option 1 shall consist of the use of low-VOC content coatings as applied, excluding water and exempt compounds, as specified in table 1212-3, below:

2. (2) Stencil coatings applied on clear or translucent substrates;
3. (3) Clear or translucent coatings;
4. (4) Coatings applied at a paint manufacturing facility while conducting performance tests on the coatings;
5. (5) Any individual coating category used in volumes less than 50 gallons in any one year, if substitute compliant coatings are not available, provided that the total usage of all such coatings does not exceed 200 gallons per year, per facility;
6. (6) Reflective coating applied to highway cones;
7. (7) Mask coatings that are less than 0.5 millimeter thick when dried and the area coated is less than 25 square inches;
8. (8) EMI/RFI shielding coatings; and
9. (9) Heparin-benzalkonium chloride (HBAC)-containing coatings applied to medical devices, provided that the total usage of all such coatings does not exceed 100 gallons per year, per facility.
