15A NCAC 02D .0912      GENERAL PROVISIONS ON TEST METHODS AND PROCEDURES

(a)  The owner or operator of any volatile organic compound source required to comply with rules in this Section shall demonstrate compliance by the methods described in 15A NCAC 02D .2600, if the test method is not stated in the Rule governing that source. The owner or operator of a volatile organic compound source shall demonstrate compliance when the Director requests such demonstration.

(b)  If the volatile organic compound emissions test shows noncompliance, the owner or operator of the volatile organic source shall submit, along with the final test report, the proposed corrective action.

(c)  Compliance shall be determined on a line-by-line basis using the more stringent of the following two:

(1)           Compliance shall be determined on a daily basis for each coating line using a weighted average by dividing the sum of the mass in pounds of volatile organic compounds in coatings consumed on that coating line, as received, and the mass in pounds of volatile organic compound solvents added to the coatings on that coating line by the volume in gallons of coating solids consumed during that day on that coating line; or

(2)           Compliance shall be determined as follows:

(A)          When low solvent or high solids coatings are used to reduce emissions of volatile organic compounds, compliance shall be determined instantaneously.

(B)          When add on control devices, such as solvent recovery systems or incinerators, are used to reduce emissions of volatile organic compounds, compliance shall be determined by averaging emissions over a one-hour period.
