TITLE 326 AIR POLLUTION CONTROL DIVISION
SECOND NOTICE OF COMMENT PERIOD
LSA Document #15-427
VOLATILE ORGANIC LIQUID STORAGE TANK EMISSIONS
The Indiana Department of Environmental Management (IDEM) is soliciting public comment on amendments to rules at
326 IAC 8-9 concerning stationary liquid storage vessels used to store volatile organic liquids (VOL) that are located in Clark, Floyd, Lake, or Porter counties. 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
IDEM received a request to allow industry sources to use an alternative inspection method to demonstrate compliance with
326 IAC 8-9 concerning VOL storage vessels. This rule applies to sources in Clark, Floyd, Lake, and Porter counties that use large storage vessels to store VOLs that are primarily in the petroleum refining, storage, and distribution industry. This rule is applicable to these four counties because these areas have previously been designated by the United States Environmental Protection Agency (U.S. EPA) as nonattainment for ozone, and, therefore, these requirements must remain in the state rules. Pursuant to
326 IAC 8-1-5, a source may petition IDEM to request a site-specific Reasonably Available Control Technology (RACT) plan as an alternative compliance method to the requirements specified in
326 IAC 8. These large storage vessels contain petroleum products that have the potential to release volatile organic compounds (VOC) to the atmosphere during the filling and emptying processes. Tanks that are subject to any provision of the New Source Performance Standards (NSPS) for Volatile Organic Liquid Storage Vessels (40 CFR 60, Subpart Kb) are exempt from this rule.
U.S. EPA has established National Ambient Air Quality Standards (NAAQS) for ozone that are designed to protect human health and the environment. Ozone is formed through a photochemical reaction with certain VOCs and nitrogen oxides (NOx) that react in the presence of sunlight and warm temperatures. VOCs are present in many industries and activities, including surface coating, furniture finishing, automobile refinishing, organic solvent degreasing, industrial adhesives, and all petroleum sources.
Indiana's rule at
326 IAC 8-9 requires an inspection process for each affected tank at specific time intervals. If a tank is in use when it is time for an inspection, the tank must be emptied, degassed, inspected, and then refilled. This requirement is not only costly to sources because of the downtime and raw materials spent on this inspection process, but it also actually increases VOC emissions and, therefore, potential ozone formation, each time the tank is emptied, degassed, and refilled. This rulemaking would provide affected sources the flexibility to comply with the inspection requirements using alternative inspection methods to inspect while the tank is still in use, rather than emptying it for the purpose of inspections.
This rule also clarifies language for clarity, and addresses an inconsistency in the language in two separate parts of the existing rule regarding the calculation of maximum true vapor pressure (MTVP), and updates several references, makes corrections, and addresses standard language and style changes that have occurred over time since this rule was last revised. IDEM has been discussing this rulemaking with U.S. EPA and will continue to coordinate with U.S. EPA during the rulemaking. The final rule will be submitted to U.S. EPA for approval as an amendment to the state implementation plan.
In the First Notice of Comment Period, published in the Indiana Register on December 16, 2015, IDEM sought comment from the public on whether to expand the applicability to all sources statewide to offer them the opportunity to also use alternative inspection methods to inspect while the tank is in use. IDEM received a comment to keep the scope of the applicability as it currently applies, and not expand it statewide because it would cause some sources located in other counties across the state to be subject to new requirements in order to utilize the inspection benefit. Therefore, upon further consideration, IDEM has agreed that the applicability should only include the current four counties and not be expanded statewide. IDEM seeks comment on the affected citations listed, including suggestions for specific language, any other provisions of Title 326 that may be affected by this rulemaking, and alternative ways to achieve the purpose of the rulemaking.
IC 13-14-9-4 Identification of Restrictions and Requirements Not Imposed under Federal Law
No element of the draft rule imposes either a restriction or a requirement on persons to whom the draft rule applies that is not imposed under federal law.
This rulemaking will have a potential positive fiscal impact for each affected source in Clark, Floyd, Lake, and Porter counties, as the tanks become due for inspections because the costs of downtime and raw material to take a tank offline for an inspection could be eliminated or reduced. Additionally, this alternative will have a positive fiscal impact for the general public by reducing ozone emissions, which will improve the health of the public and, therefore, help to reduce health care costs. It will also help Indiana meet the new ozone NAAQS adopted by U.S. EPA. As counties become designated as attainment for the ozone standard because of cleaner air, there is potentially a positive economic impact on the area because it becomes more attractive to both residents and businesses.
Public Participation and Work Group Information
At this time, no work group is planned for the rulemaking. If you feel that a work group or other informal discussion on the rule is appropriate, please contact Jack Harmon, Rules Development Branch, Office of Legal Counsel at (317) 234-9535 or (800) 451-6027 (in Indiana).
SUMMARY/RESPONSE TO COMMENTS FROM THE FIRST COMMENT PERIOD
IDEM requested public comment from December 16, 2015, through January 15, 2016, on alternative ways to achieve the purpose of the rule and suggestions for the development of draft rule language. IDEM received comments from the following party by the comment period deadline:
SABIC Innovative Plastics US LLC, Mount Vernon, Indiana (SABIC)
Following is a summary of the comments received and IDEM's responses thereto:
Comment: The commenter stated support for IDEM's proposal to allow an alternative inspection method to demonstrate compliance with the emission limits. The commenter agrees that it will likely be a financial advantage to those regulated entities using the alternative methods, and that the new method would reduce VOC emissions during the required inspections. (SABIC)
Response: IDEM appreciates the support from the commenter, and agrees that VOC emissions may be reduced under the proposed rulemaking.
Comment: IDEM should keep the scope of applicability limited to the current counties of Lake, Porter, Clark, and Floyd, and not expand to the rest of the state of Indiana. Sources in other counties are not currently subject to the rule, and imposing a requirement where the rule doesn't even apply is just adding another group of requirements, with no benefit. (SABIC)
Response: The Clean Air Act Amendments of 1990 required that states in areas that were designated as ozone nonattainment at a level of moderate or worse, develop plans to reduce emissions of VOCs, precursors to ozone, by 15% by 1996. The areas in Indiana designated nonattainment for ozone at the level of moderate or worse were Clark, Floyd, Lake, and Porter counties. VOL storage vessels were among the categories of sources for which the U.S. EPA issued Control Technique Guidelines (CTG) for states to use in order to achieve and maintain the 15% reduction in VOCs. The provisions in
326 IAC 8-9-5 were based on the CTG for VOL storage vessels. Therefore, IDEM agrees that the applicability of this rule should not be expanded beyond Clark, Floyd, Lake, and Porter counties.
Comment: Pursuant to
326 IAC 8-9-1, any tank that is subject to the requirements of NSPS Subpart Kb is exempt from the requirements of this rule. This concept should be expanded to include any storage tank that stores an organic hazardous air pollutant (OHAP) that is also a VOC, and that is subject to any provision of a 40 CFR 63 Maximum Achievable Control Technology (MACT) standard. When a MACT standard requires control requirements on a tank, the controls are very similar to those required in this rule. If a MACT standard doesn't require controls, its requirements are comparable to those of Subpart Kb when no control is required under federal rule. The MACT standards should form the basis for an exemption from this rule, just as Subpart Kb does. (SABIC)
Response: IDEM has discussed the possible changes to the VOL RACT rule with U.S. EPA. IDEM and U.S. EPA agree that, if a source is complying with the control requirements in 40 CFR 63, Subpart WW (National Emission Standards for Storage Vessels), that it would be reasonable to exempt that source from the RACT requirements in
326 IAC 8-9. However, 40 CFR 63, Subpart WW has no explicit applicability criteria, but is, instead, referenced by other subparts. Therefore, appropriate language will need to be inserted into the exemption clause to make the exemption acceptable. The IDEM draft rule has been changed to include some exemption language, and the National Emission Standard for Hazardous Air Pollutants at 40 CFR 63, Subpart WW will be incorporated by reference into the rule.
Comment: Please change the pounds per square inch absolute (psia) threshold in
326 IAC 8-9 (0.5000 psia) to be the same as the psia threshold in NSPS Subpart Kb (0.5076 psia); it would be less confusing and more consistent to have one standard. (SABIC)
Response: The initial rulemaking was intended to simplify the inspection requirements for tank owners as well as ensure that VOC emissions are not increased by otherwise unscheduled emptying and degassing of tanks. IDEM has not changed the applicability exemption threshold in
326 IAC 8-9-1(c). The standards set forth in
326 IAC 8-9-4 only apply to tanks equal to or greater than 39,000 gallons that store VOL with a maximum true vapor pressure of greater than or equal to 0.75 psia. Likewise, the requirements of
326 IAC 8-9-5 only apply to tanks subject to the standards set forth in
326 IAC 8-9-4. Changing the applicability threshold in
326 IAC 8-9-1(c) would subject fewer VOL tanks to the record keeping requirements of
326 IAC 8-9-6 and would constitute a lessening of the stringency of the requirement, or backsliding. Federal law does not allow backsliding, therefore, the applicability threshold has not been changed.
