NR 440.47. The average monthly tonnage of grain received shall be calculated by dividing the cumulative tonnage of grain received since January 1 of each year by 12. The average monthly tonnage of grain received does not include product that the facility receives that is packaged when received and remains packaged.

NR 406.04(1)(d)(d) Portland concrete batch plants which produce or will produce less than 20,000 cubic yards of concrete per month averaged over any 12 consecutive month period.

NR 406.04(1)(e)(e) Storage tanks containing organic compounds with a true vapor pressure in pounds per square inch absolute at 70°F of less than 1.52 with a combined total tankage capacity of not more than 40,000 gallons.

NR 406.04(1)(f)(f) VOC storage tanks with a combined total tankage capacity of not more than 10,000 gallons of volatile organic compounds.

NR 406.04(1)(g)(g) Painting or coating operations, including associated cleaning operations, which emit or will emit not more than 1666 pounds of volatile organic compounds per month, which are measured prior to entering any emission control devices, unless the emissions of any single hazardous air pollutant listed under section 112 (b) of the Act (42 USC 7412(b)) equal or exceed 10 tons per year or the cumulative emissions of hazardous air pollutants listed under section 112 (b) of the Act equal or exceed 25 tons per year.

NR 406.04(1)(gm)(gm) Automobile refinishing operations, including associated cleaning operations, which emit or will emit not more than 1666 pounds of volatile organic compounds per month, which are measured prior to entering any emission control devices, unless the emissions of any single hazardous air pollutant listed under section 112(b) of the Act (42 USC 7412(b)) equal or exceed 10 tons per year or the cumulative emissions of hazardous air pollutants listed under section 112(b) of the Act equal or exceed 25 tons per year.

NR 406.04(1)(h)(h) Graphic arts operations, including associated cleaning operations, which emit or will emit not more than 1666 pounds of volatile organic compounds per month, which are measured prior to entering any emission control devices, unless the emissions of any single hazardous air pollutant listed under section 112 (b) of the Act equal or exceed 10 tons per year or the cumulative emissions of hazardous air pollutants listed under section 112 (b) of the Act equal or exceed 25 tons per year.

NR 406.04(1)(i)(i) A temporary change in the method of operation or temporary equipment used or to be used for the purpose of testing or research provided that all of the following requirements are met:

NR 406.04(1)(i)1.1. A complete application for exemption is made describing the proposed testing or research and including an operating schedule and the types and quantities of emissions anticipated.

NR 406.04(1)(i)2.2. The department determines that the anticipated emissions from the testing or research will not present a significant hazard to public health, safety or welfare or to the environment and approves the application for exemption.

NR 406.04(1)(i)3.3. The temporary change in the method of operation or temporary equipment will be in operation for less than 12 months. Upon completion of the testing, the temporary change in the method of operation or operation of temporary equipment shall cease. Operation beyond the testing period is prohibited unless approved by a different construction permit exemption or by a construction permit.

NR 406.04(1)(i)4.b.b. The department may provide public notice of an application for research and testing exemption, may provide an opportunity for public comment and an opportunity to request a public hearing and may hold a public hearing on any application under this paragraph.

Hourly emissions shall be determined, based on the quantitative estimate of air contaminants before they enter any emission control devices, by dividing the total uncontrolled emissions which would have occurred during a calendar month by the total hours of operation of the laboratory during that calendar month.
