TITLE 326 AIR POLLUTION CONTROL BOARD
FIRST NOTICE OF COMMENT PERIOD
LSA Document #09-364
DEVELOPMENT OF AMENDMENTS TO RULES CONCERNING FUEL GRADE ETHANOL PRODUCTION AT DRY MILLS
The Indiana Department of Environmental Management (IDEM) is soliciting public comment on amendments to rules at
326 IAC 8-1 and
326 IAC 8-5-6 concerning fuel grade ethanol production at dry mills. IDEM seeks comment on the affected citations listed and any other provisions of Title 326 that may be affected by this rulemaking.
SUBJECT MATTER AND BASIC PURPOSE OF RULEMAKING
Basic Purpose and Background
To increase the clarity, predictability, and timeliness of air permits for fuel grade ethanol production, IDEM finalized a rulemaking (LSA Document #05-197) on February 20, 2007, for fuel grade ethanol production at dry mills that have no wet milling operations under new rule
326 IAC 8-5-6. This rulemaking created an industry-specific best available control technology (BACT) standard for new fuel grade ethanol production dry mills that replaced the otherwise required case-by-case BACT determination under
326 IAC 8-1-6 for new facilities with the potential to emit 25 tons or more of volatile organic compound (VOC) emissions per year. This rule applies to fuel grade ethanol production plants that were constructed or modified after April 1, 2007, that are: (1) dry mills that have no wet milling operations, (2) use fermentation, distillation, and dehydration to produce ethanol and dried distillers grain and solubles (DDGS), and (3) have combined potential VOC emissions of 22.7 megagrams (25 tons) or more per year from fermentation processes, DDGS dryer or dryers, and ethanol load-out operations.
The current rule requires that the owner or operator of a fuel grade ethanol production plant that is a dry mill install and operate at least one of the following control devices for VOC emissions from the plant:
(1) A thermal oxidizer with an overall control efficiency of not less than 98% or resulting in a VOC concentration of not more than 10 parts per million (ppm).
(2) A wet scrubber with an overall control efficiency of not less than 98% or resulting in a VOC concentration of not more than 20 parts per million (ppm).
(3) An enclosed flare with an overall control efficiency of not less than 98%.
IDEM submitted a revision to the U.S. EPA for the Indiana state implementation plan (SIP) on March 30, 2007, to add
326 IAC 8-5-6, fuel grade ethanol production at dry mills. The final rule was approved and became effective on March 21, 2008. Since this effective date, new control technologies have been identified for fuel grade ethanol production, such as carbon adsorption, that achieve the required overall control efficiency of not less than 98%. Therefore, IDEM is proposing, in this rulemaking, to amend
326 IAC 8-5-6 to allow dry mills to install and operate additional types of control devices for VOC emissions, in addition to a thermal oxidizer, wet scrubber, or enclosed flare, such as carbon adsorption, as long as the control device achieves the required overall control efficiency of not less than 98% and the owner or operator of the plant verifies initial and continuing compliance with the control efficiency requirement. IDEM is also proposing to amend
326 IAC 8-1 to clarify the general provisions that pertain to fuel grade ethanol production.
Upon completion of the rulemaking, this rule will be submitted to the U.S. EPA for approval as a revision to the SIP.
Alternatives To Be Considered Within the Rulemaking
Alternative 1. Amend
326 IAC 8-5-6 to allow alternative control devices for VOC emissions that will achieve the required overall control efficiency of not less than 98%.
• Is this alternative an incorporation of federal standards, either by reference or full text incorporation? No.
• Is this alternative imposed by federal law or is there a comparable federal law? This alternative is not imposed by federal law and there is no comparable federal law. It is a "state-only" requirement.
• If it is a federal requirement, is it different from federal law? Not applicable.
• If it is different, describe the differences. Not applicable.
Alternative 2. Amend
326 IAC 8-1 to clarify the general provisions that pertain to fuel grade ethanol production.
• Is this alternative an incorporation of federal standards, either by reference or full text incorporation? No.
• Is this alternative imposed by federal law or is there a comparable federal law? This alternative is not imposed by federal law and there is no comparable federal law. It is a "state-only" requirement.
• If it is a federal requirement, is it different from federal law? Not applicable.
• If it is different, describe the differences. Not applicable.
Alternative 3. Do not amend the rule.
• Is this alternative an incorporation of federal standards, either by reference or full text incorporation? No.
• Is this alternative imposed by federal law or is there a comparable federal law? No.
• If it is a federal requirement, is it different from federal law? Not applicable.
• If it is different, describe the differences. Not applicable.
There is no applicable federal law.
Potential Fiscal Impact of Alternative 1. There is no fiscal impact on existing sources since they are already subject to the current industry-specific BACT standard. For new sources, the rule amendments should not impose additional costs but allow sources more options in selecting appropriate control devices.
Potential Fiscal Impact of Alternative 2. This alternative will clarify the general provisions that pertain to fuel grade ethanol production and will provide consistency in the rules. Therefore, IDEM anticipates no fiscal impact from the implementation of the rule amendments.
Potential Fiscal Impact of Alternative 3. This alternative will have no fiscal impact.
Small Business Assistance Information
IDEM established a compliance and technical assistance (CTAP) program under
IC 13-28-3. The program provides assistance to small businesses and information regarding compliance with environmental regulations. In accordance with
IC 13-28-3 and
IC 13-28-5, there is a small business assistance program ombudsman to provide a point of contact for small businesses affected by environmental regulations. Information on the CTAP program, the monthly CTAP newsletter, and other resources available can be found at:
