Ala. Admin. Code r. 335-3-5-.03
Current through Register Vol. 42, No. 12, September 30, 2024
Section 335-3-5-.03 - Petroleum Production(1) Applicability. This regulation applies to facilities that handle natural gas or refinery gas that contains more than 0.10 grain of hydrogen sulfide per standard cubic foot (SCF).(2) No person shall cause or permit the emission of a process gas stream containing more than 0.10 grain of hydrogen sulfide per SCF into the atmosphere unless it is properly burned to maintain the ground level concentrations of hydrogen sulfide to less than twenty (20) parts per billion beyond plant property limits, averaged over a thirty (30) minute period.(3) No person shall cause or permit the sulfur oxide emission from any facility designed to dispose of or process natural gas or refinery gas containing more than 0.10 grain of hydrogen sulfide per standard cubic foot to exceed the following: CATEGORY I COUNTIES
Available Sulfur (Long Tons/Day) Permitted Emissions of Sulfur Dioxide
Up to 5 No Limit
5 to 35 373 lbs/hour
35 to 75 0.10 lbs. SO2/lb. S processed
Over 75 0.08 lbs. SO2/lb. S processed
CATEGORY II COUNTIES
Available Sulfur (Long Tons/Day) Permitted Emissions of Sulfur Dioxide
Up to 10 No Limit
10 to 50 560 lbs/hour
50 to 100 0.10 lbs. SO2/lb. S processed
Over 100 0.08 lbs. SO2/lb. S processed
(a) The allowable emissions of sulfur dioxide are increased as follows to allow for dry acid gas streams containing less than 60 percent hydrogen sulfide: See Table at http://www.alabamaadministrativecode.state.al.us/docs/adem/MWd3ADEM5.pdf
(4) Applicability. In addition to the requirements of paragraph (3) of this Rule, the provisions of this paragraph apply to all natural gas processing facilities in Escambia County with capacities greater than 50 million standard cubic feet of sour gas per day. (a) No person shall cause or permit the emissions of total sulfur compounds, measured as sulfur dioxide, from any affected facility to exceed the following: See Table at http://www.alabamaadministrativecode.state.al.us/docs/adem/MWd3ADEM5.pdf
(b) Compliance with subparagraph (a) of this paragraph shall be determined continuously by monitors which measure the total sulfur compounds, measured as sulfur dioxide, emitted by the facility and total available sulfur to the facility or by other equivalent methods approved by the Director.(5) For purposes of this Rule, the following counties are classified as Category I Counties: Jackson, Jefferson, and Mobile. The remaining counties in the state are classified as Category II Counties.(6) Compliance with this Rule shall be determined by both material balances and stack sampling. New plants are required either to install monitors to continuously determine the sulfur oxide emissions in terms of mass per unit of time or to determine the sulfur oxide emissions by other means approved by the Director.(7) In calculating the ground level concentration that results from short-term waste gas or emergency flaring, it shall be assumed that only seventy-five percent (75%) of the heat of combustion is used to heat the products of combustion.(8) Air Quality Demonstration. In addition to the requirements of paragraph (3) of this Rule, every owner or operator of a facility covered by Rule 335-3-5-.03 shall demonstrate, to the satisfaction of the Director, that the sulfur oxides emitted, either along or in conjunction with other sources, will not interfere with attainment and maintenance of any primary or secondary ambient air quality standard.(9) To ensure that ambient air quality standards are met, an annual review of Sulfur Dioxide Category I and II Counties will be made by the staff. Initial Sulfur Dioxide Category Classifications and any subsequent changes to Sulfur Dioxide Category Classifications will be the subject of a public hearing. Authors: James W. Cooper, John E. Daniel
