1. (1) Process emission sources located in or significantly impacting on the Copper Basin Additional Control Area shall emit no emissions in excess of the following where each value is a three hour average on a dry basis of parts per million sulfur dioxide by volume:

   1. (a) Reserved
   2. (b) Liquid Sulfur Dioxide Plants 375 PPM
   3. (c) Organic Chemical Plants 50 PPM
   4. (d) Reserved
   5. (e) Reserved Where the general test methods specified in other chapters of these regulations cannot physically be applied to determine emissions from a particulate source, then it shall be tested in accordance with the method specified by the Technical Secretary, considering testing cost and achieving a reliable measure of the true emissions.

2. (2) (a) During startup and shutdown of process emission sources as indicated in this paragraph, the sources indicated may operate in excess of the standards in paragraph (1). Maximum allowable emissions for these processes at these times are as indicated in Table 1. Where malfunctions occur which are beyond the control of the source operator and the emission levels exceed the allowable standards as stipulated in Table 1 of this paragraph, then these cases will be considered under Chapter 1200-03-20 of these regulations. FOR ADDITIONAL CONTROL AREAS Table 1 Startup/Shutdown Allowable SO2 Levels Allowable Allowable for Allowable for for Concurrent Non-Concurrent Process Startup/Shutdown Startup/Shutdown Startup/Shutdown Emission Source 24 hour average 3 hour average 3 hour average Sulfuric Acid Plants 800 PPM 1200 PPM 1400 PPM Liquid Sulfur Dioxide Plants 600 PPM 900 PPM 1000 PPM

   1. (b) Reserved
   2. (c) All concentrations are parts per million by volume, dry basis.
   3. (d) All other sources must meet the general emission standards in other paragraphs of this rule or Chapter 1200-03-14 even during startups and shutdowns.
3. (3) All liquid sulfur dioxide plants in existence prior to January 1, 1978, must exhaust any emissions through a stack at least 126 feet in vertical distance above grade directly below the tip of the stack.
4. (4) (Reserved)

5. (5) (a) No owner or operator shall burn in any non-process fuel burning equipment located in or significantly impacting on the Copper Basin additional control area a #1 or #2 fuel oil with a sulfur weight content exceeding 0.500 percent nor shall such owner or operator burn in any non-process fuel burning equipment a #4, #5, or #6 fuel oil with a sulfur weight content exceeding 1.25 percent.

   1. (b) For any process emission source or incinerator located in or significantly impacting on the Copper Basin additional control area for which there is no sulfur dioxide stack standard (PPM) contained within Rule 1200-03-19-.19 of these regulations, the owner or operator shall not burn a #1 or #2 fuel oil with a sulfur weight content exceeding 0.500 percent nor shall such owner or operator burn in the process emission source or incinerator a #4, #5, or #6 fuel oil with a sulfur weight content exceeding 1.25 percent.
   2. (c) A higher sulfur content fuel may be utilized, but only where air pollution controls limit sulfur dioxide emissions to the amount that the specified fuels alone would result in and only after this has been specifically allowed and detailed as conditions on the operating permits. A stack test must be submitted to verify the effectiveness of the controls.
   3. (d) For any process emission source in which fuel is burned and a standard is presently stipulated in paragraph 1200-03-19-.19(1) of these regulations then such source shall not be limited in the sulfur content of fuel provided such source meets process standards contained in Rule 1200-03-19-.19.
   4. (e) (Reserved)
   5. (f) The owner or operator of an air contaminant source with restricted operating hours must maintain a daily log of operating hours and keep it available for inspection by Division personnel on request for at least one year after the end of any calendar year included in the log. The owner or operator shall submit by letter on or before January FOR ADDITIONAL CONTROL AREAS 31 of each year the total hours or operation for the previous calendar year and/or the maximum daily operation for said calendar year.
