N.H. Code Admin. R. Env-A 1212.04 – VOC Limits for Miscellaneous Metal Parts and Products Coating

Except as specified in Env-A 1212.05, the owner or operator of a miscellaneous metal parts and products coating operation subject to this part 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:

(a) Subject to (b), below, control option 1 shall consist of the use of low-VOC content coatings as applied, excluding water and exempt compounds, as specified in table 1212-1, below:

(b) Until January 1, 2016, the content limit for the following coatings shall be as specified:
1. (1) For air-dried general, one component and general, multi-component coatings, 0.42 kg VOC/l, equivalent to 3.5 lb VOC/gallon; and
2. (2) For baked general, one component and general, multi-component coatings shall be 0.36 kg VOC/l, equivalent to 3.0 lb VOC/gallon;
(c) Control option 2 shall consist of using a combination of low-VOC content coatings and one or more add-on controls to meet the limits calculated pursuant to Env-A 1205.01 or specified in table 1212-2, below:
