N.H. Code Admin. R. Env-A 1209.02 – Compliance Standards for Metal Furniture Coating

Those processes applying any coating, including but not limited to paints, sealants, caulks, inks, adhesives, and maskants, onto metal furniture or parts of metal furniture, including but not limited to tables, benches, chairs, file cabinets, and waste baskets, shall comply with one or more of the following control options:

(a) Subject to (b) and (c), below, control option 1 shall consist of emission limits expressed in terms of mass of VOC per volume of coating as applied, excluding water and exempt compounds, as specified in table 1209-1, below:

(b) If a specific coating is subject to more than one emission limit, the least stringent emission limit shall apply;
(c) Until January 1, 2016, the emission rate for both general, one component and general, multi-component coatings shall be 0.36 kg VOC/l, equivalent to 3.0 lb VOC/gallon, for existing sources;
(d) Subject to (e), below, control option 2 shall:
1. (1) Be calculated pursuant to Env-A 1205.01; or
2. (2) Consist of equivalent emission limits expressed in terms of mass of VOC per volume of solids as applied, using an assumed VOC density of 7.36 pounds per gallon, as specified in table 1209-2, below:
