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 Section .2600 of this Subchapter. 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 proposed corrective action. (c) Compliance shall be determined on a line-by-line basis using the more stringent of the following two: (1) (2) Compliance shall be determined on a daily basis for each coating line using a weighted average, that is, dividing the sum of the mass (pounds) of volatile organic compounds in coatings consumed on that coating line, as received, and the mass (pounds) of volatile organic compound solvents added to the coatings on that coating line by the volume (gallons) of coating solids consumed during that day on that coating line; or Compliance shall be determined as follows: (A) (B) When low solvent or high solids coatings are used to reduce emissions of volatile organic compounds, compliance shall be determined instantaneously. When add on control devices, e.g., 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.
