Section II.A.1 -Except as provided in paragraphs 2 through 6 below,no owner or operator of a source shall allow or cause the emission
into the atmosphere of any air pollutant which is in excess of 20%opacity.This standard is based on 24 consecutive opacity readings
taken at 15-second intervals for six minutes.The approved reference test method for visible emissions measurement is EPA Method 9(40
CFR, Part 60,Appendix A(July, 1992)) in all subsections of Section II.A and B of this regulation.
Section II.A.5-Smokeless Flare or Flares for the Combustion of Waste Gases No owner or operator of a smokeless flare or other flare for
the combustion of waste gases shall allow or cause emissions into the atmosphere of any air pollutant which is in excess of 30%opacity
for a period or periods aggregating more than six minutes in any sixty consecutive minutes.

to result in detectable odors which are measured in excess of the following limits: For areas used predominantly for residential or
commercial purposes it is a violation if odors are detected after the odorous air has been diluted with seven(7)or more volumes of odor
free air.
Regulation 6-New Source Performance Standards
NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84.
This source is not subject because each tank is less than 19,800 gallons(471 bbl)
NSPS OOOO:for storage vessels in the natural gas production,transmission,and processing segments.
This source is not subject because each tank emits less than 6 tpy VOC.
Re ulation 7—Volatile Or anic Com ounds
XII.VOLATILE ORGANIC COMPOUND EMISSIONS FROM OIL AND GAS OPERATIONS
(Applicant is subject to the emission control requirements for condensate tanks since it is located in a non attainment area.)
XVII.C STATEWIDE CONTROLS FOR OIL AND GAS OPERATIONS...
(Applicant is not currently subject to this since actual uncontrolled emissions are greater than 20 tpy of VOC.)
