Page1of5ActionInitiationList–April2011U.S. Environmental Protection Agency (EPA)April 2011 Action Initiation List (as of 5/24/2011)The following actions were initiated by EPA this month. Explanations of which EPA actions are included on this list and ofeach element of the table can be found at the end of this document.The two most recent Action Initiation Lists (AILs) can always be found at:http://www.epa.gov/lawsregs/search/ail.html.But, they will not provide updates on the actions listed herein.Updates on priority rulemakings are available from EPA'sRulemaking Gateway (www.epa.gov/rulemaking/).If one of the rules on this AIL is in the Rulemaking Gateway, a linkto the rule's profile is included in the table below. Forall rules – those that are in the Gateway and those thatare not – you may obtain updates twice a year in EPA’sSemiannual Regulatory Agenda,which is accessible from these Web sites:• EPA’s Laws, Regulations, Guidance and Dockets(http://www.epa.gov/lawsregs/search/regagenda.html)• RegInfo.gov(http://www.reginfo.gov/public/do/eAgendaMain)• Regulations.gov(http://www.regulations.gov/fdmspublic/component/main?main=UnifiedAgenda&agency=EPA&pubperiod=200710)To assist you in tracking actions’ progress, the RINs in the table below are also displayed in theSemiannual RegulatoryAgendaand the Rulemaking Gateway.Page2of5ActionInitiationList–April2011RINAction TitleStageContactAbstractProjectedPublicationDate2012-AA02 Revisions to FederalImplementationPlans Under theClean Air Act forIndian Country inIdaho, Oregon andWashingtonNPRM Anne Dalrymple206-553-6313Dalrymple.Anne@epa.govAfter five years of experience implementing theFederal Air Rules for Reservations, R10 is ready torevise the original rules to apply to all Indian Country,including new reservations in R10. We also want torevise the rules to align more with implementation andto better address sources of air pollution on IndianReservations in ID, OR and WA.12 monthsor less2060-AQ98 Protection ofStratosphericOzone: Adjustmentsto the AllowanceSystem forControllingHydrochlorofluorocarbon Production,Import, and Exportfor 2012NPRM Luke Hall-Jordan202-343-9591Hall-Jordan.Luke@epa.govIn 2009, EPA finalized a rule allocatinghydrochlorofluorocarbon (HCFC) allowances for the2010-2014 control periods (74 FR 66412). Twoallowance holders challenged how EPA establishedthe baselines for HCFC-22 and HCFC-142b in theU.S. Court of Appeals for the District of ColumbiaCircuit. The Court vacated the rule in part andremanded it to EPA. This rulemaking responds to theCourt's decision with respect to the 2012 controlperiod. EPA intends to issue a separate notice andcomment rulemaking to address future control periods.12 monthsor lessPage3of5ActionInitiationList–April2011RINAction TitleStageContactAbstractProjectedPublicationDate2060-AQ99 National EmissionStandards forAerospaceManufacturing andRework FacilitiesRisk and TechnologyReviewNPRM Kim Teal919-541-5580Teal.Kim@epa.govOn September 1, 1995 (60 FR 45948), wepromulgated the National Emission Standards forAerospace Manufacturing and Rework Facilities (40CFR part 63, subpart GG) under section 112(d) of theClean Air Act (CAA). The National EmissionStandards for Hazardous Air Pollutants (NESHAP)sets Maximum Achievable Control Technology(MACT) standards for existing and new major sourcesof hazardous air pollutant (HAP) emissions andincludes standards to control volatile organiccompounds (VOC) emissions. Under CAA section112(d)(6) EPA is required toreview standards issuedunder Section 112 and to revise them "as necessary(taking into account developments in practices,processes and control technologies)" no lessfrequently than every 8 years. EPA also must evaluatethe MACT standards within8 years after promulgationand promulgate standards under CAA section 112(f)(2) if required to provide an ample margin of safetyto protect public health or prevent an adverseenvironmental effect. Thesource category will beassessed for inhalation risks,including cancer risk andincidence, population cancer risk, and non-cancereffects (chronic and acute). We also plan to evaluatemultipathway risk associated with those sourcecategories with significant levels of persistent andbioaccumulative HAP. We will follow the BenzenePolicy to identify the source categories as low risk,acceptable risk, or unacceptable risk. EPA will thenevaluate the effectiveness andcost of additional riskreduction options and make acceptability and amplemargin-of-safety determinations. If the need foradditional controls is identified, the standards willinclude technology, work practice, or performancestandards as amendments to the existing MACTstandards.12 monthsor lessPage4of5ActionInitiationList–April2011RINAction TitleStageContactAbstractProjectedPublicationDate2060-AR00 Uniform Standardsfor Equipment Leaksand AncillarySystems, ClosedVent Systems andControl Devices,Storage Vessels andTransfer Operations,and WastewaterOperationsNPRM Brenda Shine919-541-3608Shine.Brenda@epa.govOrganic chemical processing industries such as Oiland Gas, Petroleum Refining, and Chemicalproduction have similar emission sources that areoften required to be controlled to similar levels by thesame type of control devices and work practicestandards. The air pollution control regulatoryrequirements for thesesources have evolved andimproved as different New Source PerformanceStandards (NSPS) and Maximum Achievable ControlTechnology (MACT) have been developed over theyears. This has resulted in requirements that aredifferent and in many cases insufficient especially withrespect to ensuring continuous compliance. We havedeveloped “standardized” regulatory requirements inthe past but they are specific to Part 60, 61, and 63rules respectively and are out of date. This action willdevelop and consolidate state-of-the-art uniformstandards that will then become applicable when theyare referenced in future regulatory actions, such asnew and revised Control Technique Guidelinesdocuments, NSPS technology reviews, and MACTRisk and Technology reviews for these industries. Theuniform standards are expected to includerequirements for work practices and equipmentstandards and for monitoring, recordkeeping, andreporting requirements.Uniform standards will bedeveloped in this action for the following: 1) equipmentleaks and ancillarysystems, 2) closed vent systemsand control devices, 3) storage vessels and transferoperations, and 4) wastewater operations. In additionto developing the uniform standards, EPA alsoexpects to develop tools for the proper application ofthese uniform standards during rule development,including anticipated costs and pollutant emissionreductions.12 monthsor lessPage5of5ActionInitiationList–April2011What EPA Actions Appear on the AILs?Generally, AILs include those actions that 1) will appear in upcomingSemiannual Regulatory Agendaand 2) have been approved for commencement byEPA’s Regulatory Policy Officer. In rareinstances, an actionwill not appear on an AIL before it appears in theAgenda. Also, keep in mind that AILs will notpost immediately. You can access a given month's list roughly 15days after the close of the month (e.g., the April 2008 AIL will post sometime aroundMay 15th).What Does Each Column in the AIL Mean?RIN:RIN stands for "Regulation Identifier Number." A RIN is assigned by theRegulatory Information Service Center, a component of the U.S. GeneralServices Administration, to identify each regulatory action listed in ourSemiannual Regulatory AgendaandAnnual Regulatory Plans. Also, RINs areincluded in the headings of our rules when they are published in the Federal Register to make it easier for you to track our actions. An example of an EPARIN is 2050-AG37. It iscomposed of two parts. Thefirst part (i.e., 2050) identifies which office within EPA is in charge of the action. In this case, it is theOffice of Solid Waste and Emergency Response. The second part(e.g., AG37) is an alpha-numeric code automatically generated asrules are assigned aRIN.Title:Self-explanatory.Stage:The stage of an action describes where we are in the rule writing process, from the very beginning when a rule (or other action) is just an idea tothe end when it is published as a final rule (or other action) inthe Federal Register. For example, the Notice of Proposed Rulemaking (NPRM) stageannounces a proposed rule or proposed modification to an existing rule. In the AILs, the following acronyms are used:•ANPRM - Advance Notice of Proposed Rulemaking•NPRM - Notice of Proposed Rulemaking•Supplemental - Supplemental NPRM•Direct Final - Direct Final Action•Interim Final – Interim Final Action•Final – Final Action•Section 610 Review – Agency Review under Section 610 of the Regulatory Flexibility ActContact:Provides the name, phone, and email address for the EPA staff personassigned to this rule. Additionally, if a rule is in EPA's RulemakingGateway (www.epa.gov/rulemaking/), then a link to the rule's profile will be provided in this column.Abstract:A brief summary of the action and its purpose.Projected Publication Date:Since many variables affect how long it takes to write a rule orother action, it is difficult to predict a firm publicationdate when we have just started working on an action. Therefore, weinsert one of two options in the "Projected Publication Date" column: 1) "12 months orless" and 2) "more than 12 months." These options give yousome idea of how quickly we expect to complete an action.
