SECTION 252:100-37-25. Coating of parts and products

(a)   Standards. No owner or operator of any coating line or coating operation with VOC emissions shall use coatings that as applied contain VOCs in excess of the amounts listed below. (Limits are expressed in pounds of VOC per gallon of coating, excluding the volume of any water and exempt organic compounds.)

(1)   Alkyd primer - 4.8

(2)   Vinyls - 6.0

(3)   NC lacquers - 6.4

(4)   Acrylics - 6.0

(5)   Epoxies - 4.8

(6)   Maintenance finishes - 4.8

(7)   Custom products finish - 6.5

(b)   Plant-wide emission plan.

(1)   Development of a plant-wide emission plan. An owner or operator may develop a plant-wide emission plan instead of having each coating line comply with the VOC content limitations in 252:100-37-25(a), if the following conditions are met.

(A)   The owner or operator demonstrates by the methods in 252:100-5-2.1(d) that sufficient reductions in emissions of VOCs may be obtained by controlling other sources within the plant to the extent necessary to compensate for all excess emissions that result from one or more coating lines not achieving the limitation. Such demonstration shall be made in writing and shall include:

(i)   a complete description of the coating line or lines that can not comply with the VOC content limitation in 252:100-37-25(a);

(ii)   quantification of emissions, in terms of pounds per day of VOCs, which are in excess of the VOC content limitation for each coating line described under 252:100-37-25(b)(1)(A)(i);

(iii)   a complete description of how emissions will be decreased at specific sources to compensate for excess emissions from each coating line described under 252:100-37-25(b)(1)(A)(i) and the date on which such reductions will be achieved;

(iv)   quantification of emissions, in terms of pounds per day of VOCs, for each source described under 252:100-37-25(b)(1)(A)(iii), both before and after the improvement or installation of any applicable control system, or operational changes to such a facility or facilities to reduce emissions; and,

(v)   a description of the procedures and methods used to determine the emissions of VOCs.

(B)   The plant-wide emission reduction plan does not include decreases in emissions resulting from requirements of other applicable air pollution rules.

(2)   Compliance with a plant-wide emission plan. The implementation of a plant-wide emission reduction plan instead of compliance with the VOC content limitation prescribed in 252:100-37-25(a) must be approved in writing by the Division Director. Upon approval, any emissions in excess of those established for each facility under the plan shall be a violation of this Subchapter.

(c)   Exemption. Owners or operators of sources that emit less than 100 pounds of VOC per 24-hour day are exempt from the requirements of this Section.

(d)   Alternate standard. The use of coatings with VOC contents in excess of those permitted by 252:100-37-25(a) or 252:100-37-25(b) is allowable if both of the following conditions are met:.

(1)   VOC emissions are reduced to the quantity that would occur if the coating used complied with the VOC content allowed in 252:100-37-25(a) by:

(A)   incineration;

(B)   absorption/adsorption; or,

(C)   any other process of equivalent reliability and effectiveness.

(2)   No air pollution, as defined by the Clean Air Act, results.
