Background Information for This Final Rule Section 112(d) of the CAA requires EPA to establis h national emission standards for hazardous air pollu tants (NESHAP) for both major and area sources of HAP tha t are listed for regulation under CAA section 112(c). A major source emits or has the potential to emit 10 tons p er yearDRAFT –

DO NOTE CITE OR QUOTE 7 December 1, 2009 (tpy) or more of any single HAP or 25 tpy or more o f any combination of HAP. An area source is a stationary source that is not a major source. Section 112(k)(3)(B) of the CAA calls for EPA to identify at least 30 HAP which, as the result of em issions from area sources, pose the greatest threat to publ ic health in the largest number of urban areas. EPA implemented this provision in 1999 in the Integrate d Urban Air Toxics Strategy, (64 FR 38715, July 19, 1999). Specifically, in the Strategy, EPA identified 30 HA P that pose the greatest potential health threat in urban areas, and these HAP are referred to as the “30 urban HAP. ” Section 112(c)(3) requires EPA to list sufficient categories or subcategories of area sources to ensu re that area sources representing 90 percent of the emissio ns of the 30 urban HAP are subject to regulation. We imp lemented these requirements through the Integrated Urban Air Toxics Strategy (64 FR 38715, July 19, 1999). A primary g oal of the Strategy is to achieve a 75 percent reduction i n cancer incidence attributable to HAP emitted from stationa ry

sources. Under CAA section 112(d)(5), we may elect to promulgate standards or requirements for area sourc es "which provide for the use of generally available c ontrolDRAFT –

DO NOTE CITE OR QUOTE 8 December 1, 2009 technologies or management practices (GACT) by such sources to reduce emissions of hazardous air pollutants."

Additional information on GACT is found in the Sena te report on the legislation (Senate Report Number 101 -228, December 20, 1989), which describes GACT as: . . . methods, practices and techniques which are commercially available and appropriate for applicat ion by the sources in the category considering economic impacts and the technical capabilities of the firms to operate and maintain the emissions control systems. Consistent with the legislative history, we can con sider costs and economic impacts in determining GACT. Th is is particularly important when developing regulations for source categories, like this one, that have many sm all businesses, as defined by the Small Business

Administration. Determining what constitutes GACT involves conside ring the control technologies and management practices t hat are generally available to the area sources in the sour ce category. We also consider the standards applicabl e to major sources in the same industrial sector to dete rmine if the control technologies and management practices a re transferable and generally available to area source s. In appropriate circumstances, we may also considerDRAFT –

DO NOTE CITE OR QUOTE 9 December 1, 2009 technologies and practices at area and major source s in similar categories to determine whether such techno logies and practices could be considered generally availab le for the area source category at issue. Finally, as not ed above, in determining GACT for a particular area so urce category, we consider the costs and economic impact s of available control technologies and management pract ices on that category. We are promulgating these national emission standa rds in response to a court-ordered deadline that requir es EPA to issue standards for categories listed pursuant t o section 112(c)(3) and (k) by December 16, 2009 (Sie rra Club v. Johnson, No. 01-1537, (D.D.C., March 2006)). III. Summary of Changes Since Proposal This final rule contains several changes to the proposed rule as a result of public comments. The following sections present a summary of the changes to the proposed rule. We explain the reasons for these ch anges in detail in the summary of comments and responses (se ction V of this preamble). A. Applicability The final rule applies to any prepared feeds manufacturing facility that produces animal feed pr oducts (not including cat and dog feed products) and uses aDRAFT –

DO NOTE CITE OR QUOTE 10 December 1, 2009 material containing chromium or a material containi ng manganese. In light of questions raised concerning the scope of sources covered by this area source rule, we revised several definitions in the rule and added o ther definitions. The prepared feeds manufacturing area source category is identified by NAICS code 311119, “Other Animal Food Manufacturing.” This NAICS code includes establishments primarily engaged in manufacturing a nimal feed (except dog and cat) from ingredients, such as grains, oilseed mill products, and meat products. The NAIC S definition also contains a list of over 40 specific animal feed processes that are included in the NAICS code. First, we added a definition of “animal feed,” and defined that term to include all of the products in NAICS code 3 11119. The final rule, therefore, applies not only to “traditional” feed products, but also to animal fee d ingredients, supplements, premixes, concentrates, a nd other products included in the definition of NAICS code 3 11119. Second, we revised the definition of a “prepared fe ed manufacturing facility” to include the concept of “primarily engaged.” To meet the definition of a p repared feeds manufacturing facility, a facility must be “p rimarily engaged” in the production of animal feed. We iden tified that primarily engaged in the production of animal feedDRAFT –

DO NOTE CITE OR QUOTE 11 December 1, 2009 means that the animal feed makes up at least half o f the facility’s annual production. The definition of pr epared feed manufacturing facility explicitly states that facilities primarily engaged in feeding animals are not prepared feed manufacturing facilities. We also ad ded definitions for “a material containing chromium” an d “a material containing manganese.” ”A material contai ning chromium” is defined as any material that contains chromium in an amount greater than 0.1 percent by weight, an d “a material containing manganese” is defined as any ma terial that contains manganese in an amount greater than 1 percent by weight. We added a requirement to provide for t he situation where a facility starts using a material containing chromium or manganese after the applicab le compliance date. Specifically, facilities that are not subject to the rule but start adding materials cont aining chromium or manganese in the future become subject to the rule at the time they begin adding these HAP. Whil e the rule does not apply to prepared feeds manufacturing facilities that do not use any materials containing chromium or manganese, we added provisions that mak e it clear that facilities that stop using all materials containing chromium and manganese at a later date a re no longer subject to the rule.DRAFT –

DO NOTE CITE OR QUOTE 12 December 1, 2009 B. Standards and Compliance Requirements The final rule retains the specific housekeeping management practices discussed in the proposed rule . Those management practices require sources to reduce dust (use industrial vacuum, remove dust from walls and ledge s, keep doors shut). The only change we made to these prov isions was to require that doors be kept shut except durin g normal ingress and egress, rather than the proposed requir ement to keep doors shut “as practicable.” The final rule requires that a device be installed and operated at the loadout end of each bulk loader tha t loads products containing chromium or manganese to lessen fugitive emissions by reducing the distance between the loading arm and the truck or railcar. This is a ch ange from the proposed requirements, which specified tha t “drop

filter socks” be used on bulk loaders. The final rule requires that emissions from the pelleting process at facilities with an average dai ly feed production level exceeding 50 tons per day (tpd) be collected and routed to a cyclone designed to achie ve 95 percent or greater reduction in particulate matter (PM) emissions. This is a change from the proposed rule , which required a cyclone designed to achieve a 95 percent reduction in particulate matter emissions less than 10DRAFT –

DO NOTE CITE OR QUOTE 13 December 1, 2009 microns in diameter (PM10). To demonstrate that yo ur cyclone is designed to achieve a 95 percent reducti on in PM emissions, the final rule provides three different options: (1) manufacturer’s specifications certifying that t he cyclone is designed to achieve 95 percent PM reduct ion, (2) certification by a professional engineer or res ponsible official that the cyclone is designed to achieve a 95 percent reduction in PM emissions, or (3) a Meth od 5 performance test to demonstrate that the cyclone ca n achieve a 95 percent reduction in PM emissions. The proposed rule required that the pressure drop across the cyclone be monitored to demonstrate that the device was in good condition and operating properly . The final rule expands the monitoring options to includ e other measures that indicate proper flow through the cycl one. Specifically, the final rule allows monitoring of i nlet flow rate, inlet velocity, pressure drop, or fan am perage. C. Reporting and Recordkeeping Requirements The final rule requires that all sources that have an average daily feed production level of 50 tpd or le ss to keep production records. These facilities must als o submit their initial average daily feed production level i n the Notification of Compliance Status report.DRAFT –

DO NOTE CITE OR QUOTE 14 December 1, 2009 We added recordkeeping and reporting requirements associated with the new options on demonstrating cy clone performance efficiency (certification by profession al engineer or responsible official, or testing). We also added provisions that require facilities that disco ntinue the use of all materials containing chromium and ma nganese to notify the Agency that they are no longer subjec t to the

rule.

D. Definitions As discussed above, definitions for animal feed, a material containing chromium, a material containing manganese, and prepared feeds manufacturing facilit y were added or modified. The definition of filter drop s ock was removed, as this term is no longer used in the fina l rule. IV. Summary of Final Standards A. What are the applicability provisions and compl iance

dates? Subpart DDDDDDD standards apply to each new or existing prepared feeds manufacturing facility that is an area source and uses a material containing chromium or a material containing manganese. A prepared feeds manufacturing facility is a facility where at least half of the annual production is dedicated to animal feed ( not including dog and cat feed), supplements, premixes, andDRAFT –

DO NOTE CITE OR QUOTE 15 December 1, 2009 other animal feed ingredients. A material containi ng chromium is any material that contains chromium in an amount greater than 0.1 percent by weight, and a ma terial containing manganese is any material that contains manganese in an amount greater than 1 percent by we ight. All existing area source facilities subject to thi s rule are required to comply with the rule requireme nts no later than [INSERT DATE TWO YEARS AFTER THE DATE OF PUBLICATION IN THE FEDERAL REGISTER]. A new source is any

affected source that commenced construction or reconstruction after July 27, 2009. All new source s are required to comply with the rule requirements by [I NSERT DATE OF PUBLICATION IN THE FEDERAL REGISTER] or upo n startup, whichever is later. Prepared feeds manufacturing facilities that do no t use any materials containing chromium or manganese are not subject to this rule. If a facility starts using a material containing chromium or manganese after the applicable compliance date, they will be required t o comply at the time that they start using such materials. Also, if a facility stops using all materials containing chr omium and manganese, they are no longer subject to the ru le and must notify EPA or the delegated authority of the c hange.DRAFT –

DO NOTE CITE OR QUOTE 16 December 1, 2009

B. What are the final standards ? The final requirements, which apply to all new and existing sources, consist of equipment standards an d management practices. There are two general manage ment practices that apply in all areas where materials containing chromium or manganese are stored, used, or handled. The first is to perform housekeeping meas ures to

minimize excess dust that could contain chromium or manganese. The specific measures required by the r ule are: (1) use either an industrial vacuum system or manua l sweeping to reduce the amount of dust, (2) at least once per month, remove dust from walls, ledges, and equi pment using low pressure air or by other means, and then sweep or vacuum the area, and (3) keep doors shut except dur ing normal ingress and egress. The second general management practice is the requirement to maintain and operate all process equ ipment that stores, processes, or contains chromium or man ganese in accordance with manufacturers’ specifications an d in a

manner to minimize dust creation. There are also requirements that are specific to certain areas of the plant or processes at all new and existing sources. These requirements are:DRAFT –

DO NOTE CITE OR QUOTE 17 December 1, 2009

• For the storage area, all raw materials containing chromium or manganese must be stored in closed

containers.

• For mixing operations, materials containing chromiu m or manganese must be added to the mixer in a manner to reduce emissions, and the mixer must be covered at all times when mixing is occurring, except when materia ls are being added.

• For bulk loading processes where prepared feeds products containing chromium or manganese are loade d into trucks or railcars, you must use a device at t he loadout end of each bulk loader to lessen fugitive emissions by reducing the distance between the load ing

arm and the truck or railcar. In addition to the above requirements that apply to all facilities, new and existing facilities with av erage daily feed production levels exceeding 50 tpd are r equired to install and operate a cyclone to reduce emission s from pelleting and pellet cooling operations. The avera ge daily feed production level means the average amount of p repared feed product produced each operating day over an an nual period. The initial determination of the average d aily feed production level is based on the one-year peri od priorDRAFT –

DO NOTE CITE OR QUOTE 18 December 1, 2009 to the compliance date for existing sources, or the design rate for new sources. Subsequent average daily fee d production levels are then determined annually and are based on the amount of animal feed product produced in the calendar year divided by the number of days in whic h the production processes were in operation. Facilities with average daily feed production levels of 50 tpd or l ess are required to submit production information in their Notification of Compliance Status report and keep r ecords documenting their animal feed production levels. For the pelleting operations at facilities with da ily pelleting production levels exceeding 50 tpd, the f inal rule requires that PM emissions be collected and ro uted to a cyclone that is designed to achieve 95 percent or greater reduction in PM. There are three ways you can demo nstrate that your cyclone is designed to achieve 95 percent reduction in PM: (1) manufacturer specifications t hat certifying the cyclone is designed to achieve 95 pe rcent reduction in PM emissions; (2) certification by a professional engineer or responsible official that the cyclone is designed to achieve a 95 or greater perc ent reduction in PM emissions; or (3) a one-time Method 5 performance test to demonstrate that the cyclone ca n achieve a 95 percent or greater reduction in PM emi ssions.DRAFT –

DO NOTE CITE OR QUOTE 19 December 1, 2009 In addition, the final rule requires that you establish an operating parameter range that indicat es proper operation of the cyclone and then monitor th is parameter at least once per day. The specific para meters allowed to be monitored are inlet flow rate, inlet velocity, pressure drop, or fan amperage. The rang e that represents proper operation of the cyclone must be provided by the manufacturer, determined as part of the engi neering calculations demonstrating the design efficiency, o r determined based on monitoring conducted during the performance test. The final rule also requires that you maintain the cyclone in accordance with manufacturer specificati ons. If manufacturer specifications are not available, you must develop and follow standard maintenance procedures. C. What are the compliance requirements ? For all new and existing sources, compliance with t he final regulation is demonstrated through installati on of the required equipment, adherence to the management practices specified in the rule, and keeping the re quired records and submitting the required notifications a nd reports described below. To ensure that the cyclone for the pelleting and pellet cooling process is operated properly at faci litiesDRAFT –

DO NOTE CITE OR QUOTE 20 December 1, 2009 with average daily feed production levels exceeding 50 tpd, the final rule requires that the cyclone be inspect ed quarterly for corrosion, erosion, or any other dama ge that could result in air in-leakage, and that the inlet flow rate, inlet velocity, pressure drop, or fan amperag e be monitored and recorded daily to ensure that it is b eing operated in accordance with specified proper operat ing

range. The final rule also requires that the devices requi red at the loadout end of a bulk loader to lessen fugit ive emissions by containing the unloaded product within the device be inspected monthly to ensure that they are in good

condition. D. What are the notification, recordkeeping, and r eporting requirements ? All new and existing sources are required to compl y with some requirements of the General Provisions (4 0 CFR part 63, subpart A), which are identified in Table 1 of the final rule. The General Provisions include specifi c requirements for notifications, recordkeeping, and reporting. Each facility is required to submit an Initial Notification and a one-time Notification of Complia nce Status according to the requirements in 40 CFR 63.9 in the General Provisions. The Initial Notification, whic h isDRAFT –

DO NOTE CITE OR QUOTE 21 December 1, 2009 required to be submitted by existing affected sourc es not later than [INSERT DATE 120 DAYS AFTER DATE OF PUBL ICATION IN THE FEDERAL REGISTER], must contain basic inform ation about the facility and its operations. The Notific ation of Compliance Status, which is required to be submitte d 120 days after the compliance date, must contain a stat ement that the source has complied with all relevant stan dards. The Notification of Compliance Status also must inc lude the inlet flow rate, inlet velocity, pressure drop, or fan amperage range that constitutes proper operation of the cyclone used to reduce emissions from the pelleting and pellet cooling operations. Facilities not required to install and operate cyclones on their pelleting ope rations are required to submit documentation of their initi al average daily feed production level. The final rule requires that records be kept of al l notifications of compliance. The rule requires tha t records be kept documenting each inspection of a cy clone and each inspection of a device at the loadout end of a bulk loader. It also requires that the daily readi ng of cyclone inlet flow rate, inlet velocity, pressure d rop, or fan amperage be recorded. In addition, records are required of any actions taken in response to findin gs of the inspections or monitoring results outside the p roperDRAFT –

DO NOTE CITE OR QUOTE 22 December 1, 2009 operating range. Facilities with average daily fee d production levels of 50 tpd or less are required to keep records of the annual production and the number of days of operation. The final rule includes the requirement to prepare and submit an annual compliance certification, a copy o f which will need to be maintained on site. This report mu st contain a statement of whether the source has compl ied with all relevant standards and other requirements of th e final

rule. If a deviation from the standard occurred du ring the annual reporting period, or if an instance occurred where the cyclone inlet flow rate, inlet velocity, pressu re drop, or fan amperage was outside of the proper operating range submitted in the Notification of Compliance Status report, this information is required to be included in the annual report and the report needs to be submitted to the EPA Administrator or the designated authority by March 15 of the following year. All records are required to be maintained in a form suitable and readily available for expeditious review, and kept for at least five year s, the

first two of which must be onsite. V. Summary of Comments and Responses EPA received 16 public comment letters on the prop osed rule. Five of these comment letters were requests for anDRAFT –

DO NOTE CITE OR QUOTE 23 December 1, 2009 extension to the comment period, 1 leaving 11 comment letters that provided comments on the proposed rule. These comments were received from industry representative s, trade associations, state agencies, and an environmental organization. Sections V.A through V.G of this pre amble provide responses to the public comments received o n the proposed NESHAP. A. Rulemaking Process

Comment : Several commenters requested that the comment period be extended by 90 days. The comment ers had concerns about the inputs to the impacts analysis a nd requested additional time to collect and provide fa ctual information to the agency about the proposed rule’s provisions and their potential impact. Response : Due to a court-ordered deadline for promulgation of this rule (which at the time of proposal was Nov ember 16, 2009), we were unable to extend the comment per iod in response to these requests. Moreover, CAA section 307(d) requires that EPA provide a minimum of 30 days for public comment, and we provided that period for public com ment. Furthermore, consistent with section 307(d), the pr oposed rule provided the public an opportunity to request a public

DO NOTE CITE OR QUOTE 24 December 1, 2009 hearing, and no party requested such a hearing. Se e 307(d)(5)(record remains open 30 days after the dat e of the public hearing).

Comment: One commenter expressed their concerns about the process that EPA used to develop its proposed n ational emission standard for prepared feeds manufacturers. The commenter believes that EPA did not provide ample d ue process in developing the proposed rule. The comme nter pointed out that they requested a 90-day extension to the proposed rule’s comment period so that accurate inf ormation could be obtained to respond to the assumptions and estimates made by the agency. In this request, the commenter indicated that they highlighted five majo r areas of the proposed rule in which they believed EPA lac ked critical information that directly affects the prov isions within the proposed rule and its impact on prepared feeds manufacturers. Since EPA denied their request for extension of the comment period, the commenter indi cated that they were left with what they believe was an inappropriately short 30-day comment period to resp ond to a proposed rule that, if promulgated as drafted, woul d have very significant operational and economic impacts o n prepared feeds manufacturers. While cognizant of E PA’s

court-ordered mandate to issue this national emissi onDRAFT –

DO NOTE CITE OR QUOTE 25 December 1, 2009 standard, the commenter believes that the agency’s actions related to gathering industry information, timing o f the proposed rule and its response to their request for extension of the comment period are not indicative of a constructive or meaningful rulemaking process. Response : EPA strongly disagrees with the commenters’ assertion that EPA did not provide ample due proces s in developing the rule. Moreover, in developing the p roposed rule, we began engaging the prepared feed industry representatives, including the commenter, as early as the summer of 2007. We alerted industry of the Agency’ s rulemaking process in a meeting on August 27, 2007. At that same meeting, we notified industry of our inte nt to send a survey questionnaire, soliciting information on the prepared feed industry, including, but not limited to information on emissions control approaches. In conclusion, we believe that lines of communication with the industry were well established and open throughout the rulemaking process, and that the commenters had amp le opportunity to participate. B. Applicability

Comment : Two commenters stated that the rule should clarify that a prepared feeds manufacturing facilit y is a facility that produces feeds, and not a facility th atDRAFT –

DO NOTE CITE OR QUOTE 26 December 1, 2009 manufactures feed ingredients. One of the commente rs explained that although feed ingredient companies m ay predominantly manufacture ingredients for animal fe ed and be classified under the NAICS Code defining the Pre pared Feeds Manufacturing source category (NAICS 311119), they may also produce feed ingredients for human and/or companion animal consumption. Response : EPA would like to clarify that in addition to facilities that produce animal feed, facilities that manufacture feed ingredients are part of the prepar ed feeds manufacturing area source category. The category w as identified in the original section 112(k) emissions inventory through the use of the Standard Industria l Classification (SIC) code 2048, Prepared Feeds Manufacturing, except cat and dog feed. As noted b y the commenter, the NAICS code that covers this area sou rce category is 311119, which is equivalent to the SIC code used in the original source category definition. T he SIC/NAICS code for the source category includes man y segments of the prepared feed industry, including t he production of feed ingredients. Specifically, in a ddition to many other segments of the industry, NAICS code 311119, and thus the prepared feeds manufacturing area sour ce category, includes:DRAFT –

DO NOTE CITE OR QUOTE 27 December 1, 2009

• feed concentrates, animal, manufacturing;

• feed premixes, animal, manufacturing;

• feed supplements, animal (except cat, dog), manufacturing;

• micro and macro premixes, livestock, manufacturing;

• mineral feed supplements (except cat, dog) manufacturing; and

• mineral supplements, animal (except cat, dog), manufacturing. Therefore, since facilities that manufacture feed ingredients are subject to the rule, we did not mak e the change suggested by the commenter. We did, however , make changes to the applicability provisions and definit ions to clarify the various segments of the prepared feeds industry that are included in the source category and, there fore, subject to the rule (provided they use chromium or manganese). These changes include adding a definit ion of “animal feed,” which includes a list of all the pro ducts included under NAICS code 311119. While we recogni ze that chromium and manganese are not used in the producti on of many of the animal feed products in the definition, we believe that a complete listing eliminates the conf usion ofDRAFT –

DO NOTE CITE OR QUOTE 28 December 1, 2009 what types of processes are included in the source category. We would point out, however, that, even if a facility produces a listed animal feed product (e.g ., earthworm feed and bedding), it is not subject to t he rule if no chromium or manganese is used.

One of the commenters raised the issue of a facili ty that produces a product covered by the rule along w ith other similar products that would not be covered by the rule. Specifically, the commenter mentions a facil ity that produces animal feed ingredients along with feed ingredients for humans and/or cats and dogs.

We have revised the definition of “prepared feed manufacturing facility ” to incorporate this concept. Specifically, the final rule contains the following definition. Prepared feeds manufacturing facility means a facility that is primarily engaged in manufacturing animal feed. A facility is primarily engaged in manufacturing animal feed if the production of animal feed comprises greater than 50 percent of the total production of the facility on an annual basis.

Thus, a facility would be a prepared feeds manufact uring facility subject to the rule if the animal feed ing redients (not including ingredients for dog, cat, or human f eed) make up more than half of its production. In addit ion, the final rule specifies that an affected source at a p repared feeds manufacturing facility only includes the coll ection of equipment and activities necessary to produce an imal feed containing chromium or manganese. Therefore, if the ingredients for human and/or dog and cat feed at a facility primarily engaged in manufacturing animal feed were produced in equipment that is never used to produce “animal feed,” those production processes would not be part of the affected source and would not be subject to the requirements in the rule. While not specifically m entioned by the commenters, consideration of these applicabi lity issues, along with comments related to the number o f facilities in the source category, caused us to cla rify that prepared feeds manufacturing at farms and anim al feed lots is not part of this source category. Faciliti es “primarily engaged” in raising or feeding animals a re listed under different NAICS codes (e.g., 112210 – Hog and Pig Farming, 112112 – Cattle Feedlots, 112111 – Bee f CattleDRAFT –

Comment : Five commenters stated that the rule should only apply to prepared feeds manufacturing faciliti es that use or emit chromium compounds or manganese compoun ds above a specified threshold. The commenters claimed that such an approach would focus attention on facilities that a re more significant emitters of chromium and manganese and will avoid requiring extremely small facilities to compl y with

the rule with little environmental benefit. The co mmenters suggested several different threshold levels. One

commenter recommended a threshold based on establis hed Superfund Amendments and Reauthorization Act of 198 6 ( SARA) Tier II threshold quantities (10,000 pounds per yea r), while another suggested 2,000 pounds per year based on levels determined to be insignificant under the tit le V program. Another commenter noted that Toxics Relea se Inventory (TRI) regulations require a covered facil ity to report only if it manufactures or processes non-exe mpt chromium and/or manganese compounds in quantities e xceeding 25,000 pounds per year, and suggested that a thresh old be established at this 25,000 pounds per year level.

reach the threshold use level that establishes whet her a facility is subject to the rule’s provisions. Response : Although several commenters advocated for a usage threshold for chromium compounds and manganes e compounds, below which a facility would be exempt, we are not adopting any exemptions. Prepared Feeds Manufa cturing is one of the area source categories needed to meet the section 112(c)(3) requirement that we subject to regulation, (i.e., area source categories represent ing 90 percent of the emissions of chromium and manganese) . We reviewed the listing decision for this area source category and did not identify any information suggesting tha t small sources were not included in the listing decision. As such, we do not believe we can satisfy our requirem ent to regulate sources representing 90 percent of the emi ssions of Prepared Feeds Manufacturing urban HAP unless we subject

the emissions of the 30 urban HAP.

Comment : One commenter suggested that the applicability be changed to only include facilities that utilize pelletizing operations. The commenter note d that this would more adequately match the original group of prepared feeds manufacturers who were surveyed and those in the same class. The commenter also pointed out tha t the pelleting and pellet cooling process is the most significant source of pollutants, as it is estimate d to emit 90 percent or more of the total chromium and

manganese. Response : The basis for the listing of the area source category was not limited to emissions from pelleting. Thus, we conclude that the applicabilit y should remain as proposed.

1. General

Comment : One commenter stated that EPA based the proposed standard on erroneous and misguided assump tions and estimates of emissions of chromium compounds an d manganese compounds. This commenter had numerous objections to the impacts analyses (see section V.G ) and how these analyses impacted EPA’s decision to regul ate this category and specific emission points. Response : In section 112(c)(3) of the CAA, EPA is required to list “sufficient categories or subcateg ories of area sources to ensure that area source representin g 90 percent of the emissions of the 30 urban HAP are su bject to regulation.” An area source emissions inventory wa s compiled for each of the 30 urban HAP and the area source categories identified that comprised 90 percent of the emissions of each of these HAP. For the prepared f eeds manufacturing source category, this inventory was b ased on data from the 1990 Toxics Release Inventory (TRI). The TRI is an EPA inventory of annual emissions self-report ed by industry. Based on this information, EPA determine d that chromium compounds emissions and manganese compound s emissions from prepared feeds manufacturing area so urces needed to be regulated to achieve the 90 percent requirement in CAA section 112(c)(3). Therefore, t heDRAFT –

DO NOTE CITE OR QUOTE 34 December 1, 2009 decision to regulate emissions of chromium compound s and manganese compounds from the prepared feeds manufac turing industry was based on emissions data submitted dire ctly by the industry . The information and analyses referred to by the commenter were prepared to evaluate potential i mpacts of regulatory options. This information had no bea ring on the basic decision to develop regulations for the p repared feeds manufacturing area source category. The commenter is also incorrect with respect to how emission points were identified for regulation. Th ey assume that the information compiled for the impact s analyses was used as the basis to identify emission points for regulation. Rather, this decision was primaril y based on information submitted directly by the industry. Specifically, we conducted a survey of the industry , and responses were received for over 100 prepared feeds manufacturing facilities. In the responses to this survey, prepared feeds manufacturing facilities identified potential emission sources and reported controls an d management practices that were being used. This information formed the basis for the decisions rega rding the emission points and process areas for which sta ndards were proposed.DRAFT –

DO NOTE CITE OR QUOTE 35 December 1, 2009 In conclusion, the commenter raised several issues on the impacts analyses (see section V.G below). Howe ver, the issues associated with these analyses did not influ ence the basic decision to regulate this source category or the decisions on the specific emission sources that wou ld be regulated.

Comment : One commenter asserted that, “. . . The legislative history of § 112 explains that Congress intended GACT standards to reflect ‘methods, practi ces and techniques which are commercially available and app ropriate for application by sources in the category consider ing economic impacts and technical capabilities of the firms to operate and maintain emission control systems’.” The commenter also asserted that, although EPA use d its discretion to issue GACT standards and that § 1 12(d)(5) authorizes EPA to do so, that decision is subject t o administrative law requirements. The commenter ass erted that EPA’s decision is arbitrary and capricious bec ause that decision was not supported with a rational explanation. Response : As the commenter recognizes, in CAA section 112(d)(5), Congress gave EPA explicit authority to issue

alternative emission standards for area sources.DRAFT –

DO NOTE CITE OR QUOTE 36 December 1, 2009 Specifically, CAA section 112(d)(5), which is entit led “Alternative standard for area sources,” provides: With respect only to categories and subcategories of area sources listed pursuant to subsection (c) of t his

section , the Administrator may , in lieu of the authorities provided in paragraph (2) and subsectio n (f) of this section, elect to promulgate standards or requirements applicable to sources in such categori es or subcategories which provide for the use of generally available control technologies or managem ent practices by such sources to reduce emissions of hazardous air pollutants. See CAA section 112(d)(5) (Emphasis added ). There are two critical aspects to CAA section 112(d)(5). First, CAA section 112(d)(5) applies on ly to those categories and subcategories of area sources listed pursuant to CAA section 112(c). The commenter does not dispute that EPA listed the area source category no ted above pursuant to CAA section 112(c)(3). Second, C AA section 112(d)(5) provides that, for area sources l isted pursuant to CAA section 112(c), EPA “may, in lieu o f ” the authorities provided in CAA section 112(d)(2) and 1 12(f), elect to promulgate standards pursuant to CAA secti on 112(d)(5). CAA Section 112(d)(2) provides that emi ssionDRAFT –

DO NOTE CITE OR QUOTE 37 December 1, 2009 standards established under that provision “require the maximum degree of reduction in emissions” of HAP (a lso known as maximum achievable control technology or M ACT). CAA section 112(d)(3), in turn, defines what consti tutes the “maximum degree of reduction in emissions” for new and existing sources. See CAA section 112(d)(3) 2 . Webster’s dictionary defines the phrase “in lieu of” to mean “in the place of” or “instead of.” See Webster’s II New Riverside University (1994). Thus , CAA section 112(d)(5) authorizes EPA to promulgate stan dards under CAA section 112(d)(5) that provide for the us e of GACT, instead of issuing MACT standards pursuant to CAA section 112(d)(2) and (d)(3). The statute does not set any condition precedent for issuing standards under CAA section 112(d)(5) other than that the area source category or

CAA Section 112(d)(2) direct s EPA to consider whether more stringent emission reductions (so call ed beyond-the-floor limits) are technologically achievable considering, among other things, the cost of achieving the emission reduction.DRAFT –

DO NOTE CITE OR QUOTE 38 December 1, 2009 subcategory at issue must be one that EPA listed pu rsuant to CAA section 112(c), which is the case here. 3 We disagree with the commenter’s assertion that we must provide a rationale for issuing GACT standards under section 112(d)(5), instead of MACT standards. Had Congress intended that EPA first conduct a MACT analysis for each area source category, Congress would have stated so expressly in section 112(d)(5). Congress did not r equire EPA to conduct any MACT analysis, floor analysis or beyondthe-floor analysis before the Agency could issue a section 112(d)(5) standard. Rather, Congress authorized EP A to issue GACT standards for area source categories lis ted under section 112(c)(3), and that is precisely what EPA has done in this rulemaking. Although EPA need not justify its exercise of discretion in choosing to issue a GACT standard for an area source listed pursuant to section 112(c)(3), EPA st ill must

have a reasoned basis for the GACT determination fo r the particular area source category. The legislative h istory supporting section 112(d)(5) provides that GACT is to

encompass:

See CAA section 112(f)(5) (entitled “Area Sources” and prov iding that EPA is not required to conduct a review or promulgate stan dards under CAA section 112(f) for any area source category or subc ategory listed pursuant to CAA section 112(c)(3), and for which an emission standard is issued pursuant to CAA section 112(d)(5)).DRAFT –

DO NOTE CITE OR QUOTE 39 December 1, 2009 “... methods, practices and techniques which are commercially available and appropriate for applicat ion by the sources in the category considering economic impacts and the technical capabilities of the firms to operate and maintain the emissions control systems. ” The discussion in the Senate report clearly provide s that EPA may consider costs in determining what constitu tes GACT for the area source category. Congress plainly rec ognized that area sources differ from major sources, which is why Congress allowed EPA to consider costs in setting G ACT standards for area sources under section 112(d)(5), but did not allow that consideration in setting MACT floors for major sources pursuant to section 112(d)(3). This important dichotomy between section 112(d)(3) and s ection 112(d)(5) provides further evidence that Congress s ought to do precisely what the title of section 112(d)(5) st ates, i.e., provide EPA the authority to issue ”alternati ve

standards for area sources.” Notwithstanding the commenter’s claim, EPA properly issued standards for the area source categories at issue here under section 112(d)(5), and in doing so provi ded a

reasoned basis for its selection of GACT for these area source categories. As explained in the proposed ru le, EPA evaluated the control technologies and management p racticesDRAFT –

In its evaluation, EPA use d information on pollution prevention from industry t rade associations, and reviewed operating permits to ide ntify the emission controls and management practices that are currently used to control volatile and particulate HAP emissions. We also considered technologies and pra ctices at major and area sources in similar categories. Finally, even though not required, EPA did provide a rationale for why it set a GACT standard in the pro posed rule. In the proposal, we explained that the facili ties in the source categories at issue are already well con trolled for the urban HAP for which the source category was listed pursuant to section 112(c)(3). Consideration of cos ts and economic impacts proves especially important for th e wellcontrolled area sources at issue in this final acti on. Given the current, well controlled emission levels, a MACT floor determination, where costs cannot be consider ed, could result in only marginal reductions in emissio ns at very high costs for modest incremental improvement in control for the area source category.

Comment : One commenter questioned why EPA was not considering regulation for all HAP emissions. The commenter explained that, as documented in the reco rd forDRAFT –

DO NOTE CITE OR QUOTE 41 December 1, 2009 this rulemaking, that Prepared Feed Manufacturing facilities often generate emissions other than mang anese, such as arsenic and arsenic compounds, benzene, ber yllium and beryllium compounds, cadmium and cadmium compou nds, chlorine, cobalt and cobalt compounds, formaldehyde , hexane, hydrochloric acid, hydrogen fluoride, lead and lead compounds, mercury and mercury compounds, naphthale ne, nickel and nickel compounds, polycyclic organic mat ter, selenium and selenium compounds, and toluene. The commenter acknowledged that management practices an d PM controls required by the rule will likely reduce ot her metal HAP emissions to some degree; however they in dicated that the Agency failed to quantify this benefit. T he

commenter also indicated that EPA should consider c ontrols

for other HAPs that will not be co-controlled with the manganese and chromium. Response : Section 112(k)(3)(B) of the CAA requires EPA to identify at least 30 HAP emitted from area s ources that pose the greatest threat to public health in t he largest number of urban areas (the “Urban HAP”) and identify the area source categories emitting such pollutants that are or will be listed pursuant to s ection 112(c)(3).

As stated above, section 112(k)(3)(B) ad dresses the strategy to control HAP from area sources in ur ban areas and the focus of the strategy as it relates t o control of area sources is on the 30 HAP that pose the greatest threat to public health in the largest num ber of urban areas.

Se e 112(c)(3) (EPA must “ensure that area sources repre senting 90 percent of the area source emissions of the 30 h azardous air pollutants . . . are subject to regulation.”). We recognize that the source category emits other sect ion 112(b) HAP, including other urban HAP; however, as stated above, sections 112(c)(3) and 112(k)(3)(B) do not r equire the Agency to regulate the area source category for any HAP other than those for which the category was listed. As to the other urban HAP emitted from this category, we have identified other area source categories that emit t hese urban HAP and subjecting those area source categori es to regulation will satisfy the requirement to subject to regulation area sources that account for 90 percent of the

While the Agency is not required to regulate all section 112(b) HAP from area sources listed pursuan t to section 112(c)(3) and 112(k)(3)(B), section 112 of the CAA does not preclude EPA from regulating other HAP fro m these area sources at our discretion and in appropriateDRAFT –

Comment : One commenter claimed that the Agency’s proposed housekeeping practices are “overreaching,”DRAFT –

DO NOTE CITE OR QUOTE 47 December 1, 2009 “unfounded,” and “unnecessary.” The commenter beli eved that EPA had no basis for correlating housekeeping practices with ambient air concentrations of chromi um compounds or manganese compounds. The commenter also had concerns with regard to two of the specific plant-wide housekeeping requirements p roposed. The commenter argued that the requirement that dust be removed from walls, ledges and equipment at least o nce per month is not performance-orientated and fails to co nsider individual facility operations or existing manageme nt practices. The commenter also disagreed with the A gency’s assertion that air flow through open doors ‘stirs-u p’ dust and causes chromium compounds and manganese compoun ds to be emitted into the atmosphere. Therefore, the commen ter opposed the proposed requirement that affected faci lities keep doors shut, as practicable. In addition, the commenter also expressed concern over the facilitie s ability to comply with this requirement as they que stioned what would be the parameters set/used to determine that having a door shut is not practicable. The commenter noted that prepared feeds manufacturi ng facilities already comply with Occupational Safety and Health Administration’s (OSHA) Grain Handling Stand ard (29 CFR 1910.272) and the Food and Drug Administration’sDRAFT –

DO NOTE CITE OR QUOTE 48 December 1, 2009 (FDA’s) Current Good Manufacturing Practices (CGMPs ) for

Medicated Feeds (21 CFR 225) , and that they are regularly inspected by federal and state authorities. Becaus e of this, the commenter believed that EPA’s proposed housekeeping practices are unnecessary. The commen ter provided more detailed descriptions of these two pr ograms. Occupational Safety and Health Administration’s (OSHA) Grain Handling Standard (29 CFR 1910.272) : This standard requires facilities to “develop and implement a written housekeeping program that establishes the frequency and method(s)

determined best to reduce accumulations of fugitive grain dust on ledges, floors, equipment and other exposed surfaces” throughout the entire facility. OSHA’s housekeeping requirements are performance-oriented, allowing facilities the flexibility to design housekeeping programs to achieve compliance through methods that are most

effective for individual facilities and operations. FDA’s Current Good Manufacturing Practices (CGMPs) for Medicated Feeds (21 CFR 225) : The vast majority of prepared feed manufacturers are mandated to comply with CGMPs that requireDRAFT –

DO NOTE CITE OR QUOTE 49 December 1, 2009 buildings and equipment be maintained and kept in a reasonably clean and orderly manner to avoid the potential adulteration of feed products. Regarding this provision, FDA’s compliance program guidance states, “Accumulated dust or residue will be considered objectionable when

there is a likelihood that the material could contribute to significant contamination of animal feed.” Similar to the OSHA requirement, FDA’shousekeeping standard also is performanceorientated. The CGMP regulations allow facilities to implement those housekeeping practices that are effective for their individual operations and achieve compliance with the standard.

Another commenter recommended that instead of the specific requirements, facilities be required to ma intain a management plan to minimize excess dust. The comme nter said that this plan can be maintained on site, avai lable for review by the delegated authority. Response : The commenter claimed that EPA has no basis for correlating housekeeping practices with ambient air concentrations. Under section 112(k)(3)(B) of the CAA, EPA determined that chromium and manganese were 2 of th e 30 HAP which, as the result of emissions from area sources , poseDRAFT –

DO NOTE CITE OR QUOTE 50 December 1, 2009 the greatest threat to public health in the largest number of urban areas. Section 112(c)(3) of the CAA requi res EPA to list sufficient categories or subcategories of a rea sources to ensure that there are sources representi ng 90 percent of the emissions of each of the 30 urban HA P are subject to regulation. We determined that the chro mium and manganese emissions from prepared feeds manufacturi ng area sources need to be subject to regulation to meet th is 90 percent requirement for these two HAP. Additionall y, under CAA section 112(d)(5), we may elect to promulgate s tandards that represent GACT. As cited above, the legislati ve history supporting section 112(d)(5) provides that GACT is to encompass: “... methods, practices and techniques which are commercially available and appropriate for application by the sources in the category considering economic impacts and the technical capabilities of the firms to operate and maintain the emissions control systems.” Section 112(d)(5) calls for EPA to establish GACT s tandards that are designed to reduce HAP emissions. Nothing in these provisions requires EPA to justify GACT regul ations

based on a correlation between ambient concentratio ns and emissions from a specific emissions source.DRAFT –

DO NOTE CITE OR QUOTE 51 December 1, 2009 We based our GACT determinations on methods, practices, and techniques commonly employed in the prepared feeds manufacturing industry. Based on the availab le information, we concluded that every prepared feeds manufacturing facility performed general housekeepi ng practices and maintained equipment in an effort to reduce dust and thus, particulate emissions. We appreciat e the information provided by the commenter that confirms this conclusion, along with the details of the regulator y programs that require these measures. We disagree with the commenter that including GACT housekeeping practices is unnecessary. As noted ab ove, section 112(d)(5) requires EPA to establish nationa l

standards. The fact that OSHA and FDA have similar requirements has no relevance here, especially sinc e they allow facilities to establish individual (and poten tially dissimilar) standards. Therefore, the final rule m aintains specific housekeeping requirements to minimize dust and does not include a requirement to develop site-spec ific management practices. As noted above, we had information prior to proposa l that made it clear that housekeeping practices to m inimize dust were widespread. We concluded that GACT was “continual housekeeping practices to reduce dust th at canDRAFT –

DO NOTE CITE OR QUOTE 52 December 1, 2009 contain chromium compounds and manganese compounds. ” (74 FR 36985) However, we did not have information from a good cross section of the industry on specific practices employed. We solicited information from one of the major prepared feeds manufacturers to identify some speci fic practices employed in the industry, and included th em in the proposed rule. At proposal, we acknowledged th e potential limitations of the examples of practices proposed, and specifically requested comment on the se measures. We also requested additional general man agement practices commonly employed throughout the industry

. The commenter expressed concerns with regard to the proposed housekeeping practices, but they were not responsive to our request for additional practices used throughout the industry. While the commenter did n ot provide any suggestions to address their concerns ( other than the suggestion to remove the practices entirel y), we recognize the issues raised in the comments provide d on the specific management practices and have considered t hem. The commenter stated that the requirement that dust be removed from walls, ledges and equipment at least o nce per month is not performance-orientated and fails to co nsider individual facility operations or existing manageme nt practices. It is clear that all prepared feedsDRAFT –

DO NOTE CITE OR QUOTE 53 December 1, 2009 manufacturing facilities must remove dust from wall s, ledges, and equipment periodically in order to comp ly with the OSHA requirement. The commenter did not provid e any alternative to the monthly requirement, and our fol low-up calls to feed manufacturing facilities indicated th at monthly is a reasonable time frame. In fact, these calls show that many areas of the plant are cleaned more frequently than monthly. Therefore, the final rule retains the requirement to remove dust from walls, ledges, and equipment on a monthly basis. The proposed requirement to keep doors closed was t he result of a recommendation from a prepared feeds manufacturer. However, we appreciate the concerns regarding potential compliance confusion with the p roposed requirement to keep doors closed “as practicable.” Therefore, the final rule states that doors must re main closed “except during normal ingress and egress.”

Comment : One commenter expressed concern that the general housekeeping requirements would apply to al l areas of the affected facility, even though all areas of the affected facility may not be involved with the stor age and/or use of chromium compounds or manganese compo unds. Response : We agree with the commenter that there is no need to perform these management practices in ar easDRAFT –

DO NOTE CITE OR QUOTE 54 December 1, 2009 where chromium or manganese are never present. The refore, we have changed this language in the final rule to specify that the general management practices apply in “all areas of the affected source where materials containing c hromium or manganese are stored, used, or handled.”

3. Mixers

Comment : One commenter urged the Agency to eliminate the requirement that affected facilities cover the mixer where materials containing chromium compounds or ma nganese compounds are added at all times when mixing is occ urring, except when the materials are being added to the mi xer. The commenter suggested that this requirement impli es that chromium compounds or manganese compounds are being emitted into the atmosphere directly from the mixer when mi xing occurs, and they do not believe that this is true. The commenter stated that if chromium and manganese are released from a mixer, they are captured within the facility in which the mixer is operating and not di rectly released to the atmosphere. The commenter explaine d that

the facilities themselves are control devices. The

commenter claimed that there was a lack of sufficie nt and compelling data to support a contention that openin gs in mixers are a source of emissions of chromium compou nds or manganese compounds. The commenter believed that t heDRAFT –

DO NOTE CITE OR QUOTE 55 December 1, 2009 technical background information considered by EPA in this rulemaking produced an unfounded correlation betwee n mixer operation and chromium and manganese emissions. Th e commenter cited EPA’s 2002 National Emissions Inven tory (NEI) and noted that the data reviewed indicated no emissions of chromium compounds or manganese compou nds from source classification codes 31227 through 31237, wh ich encompass mixing/blending operations at feed manufa cturers. Response : The commenter stated that when chromium compounds or manganese compounds are released from the mixer they are not emitted to the atmosphere becaus e the

facilities themselves are control devices. We do n ot disagree that there may be situations where direct releases to the atmosphere from the mixing operations do not occur. In fact, of the facilities that reported informatio n for mixing in response to our industry survey, over 60 percent indicated that their processes are “closed” without direct vents to the atmosphere. However, the general vent ilationof the building can allow chromium- and manganesecontaining dust from the building to be emitted. C hromium and manganese dust created in the mixer that accumu lates in the building could be emitted. Therefore, any meas ures to reduce the amount of dust in the building impacts emissions. We believe that the proposed measures t o reduceDRAFT –

DO NOTE CITE OR QUOTE 56 December 1, 2009 dust generation from mixing will result in lower du st levels and, thus, lower emissions.

The commenter further claimed that there was no evidence that openings in mixers are a source of em issions of chromium compounds or manganese compounds, and t hat the technical background information considered by EPA in this rulemaking produced an unfounded correlation betwee n mixer operation and chromium and manganese emissions. Ho wever, we identified mixers as a source of emissions due t o information submitted directly by the industry. Specifically, prepared feeds manufacturing faciliti es identified mixing as a potential emission source an d reported associated add-on control devices and mana gement practices in response to our industry survey. We r eviewed the material submitted via this survey and agree th at it is accurate and representative. Since some prepared feeds manufacturing facilities reported that emissions from mixing were vented to a control device, we evaluated whether add-on control s were GACT for mixing operations. The commenter is corre ct that no emissions were assigned directly to mixing in th e 2002 NEI. However, we would note that over 60 percent o f the manganese emissions in the 2002 NEI, and 90 percent of the chromium emissions, were not assigned to any specif icDRAFT –

DO NOTE CITE OR QUOTE 57 December 1, 2009 operation, thus raising the possibility that some o f these emissions are occurring from mixing operations.

In order to evaluate whether it was cost effective to select add-on control as GACT, it was necessary to make assumptions based on engineering judgment to estima te emissions from mixing. While the commenter may dis agree with the assumptions that were used to estimate the se emissions, the result was the rejection of add-on c ontrol as GACT for mixing. To reiterate, the emission estimates that the commenter objects to were not a factor in establish ing the proposed management practices as GACT. That determ ination was directly based on the information submitted in response to the survey. In conclusion, the commenter provided no informatio n to suggest that the proposed measures were not gene rally available and commonly used by the facilities to re duce chromium- or manganese-containing dust from mixing operations at prepared feeds manufacturing faciliti es. The commenter also provided no information challenging our conclusion that the costs of the GACT standards in the final rule are reasonable. Therefore, no changes w ere made to the proposed requirements for mixing. 4. Pelleting and Pellet CoolingDRAFT –

DO NOTE CITE OR QUOTE 58 December 1, 2009

Comment : One commenter disagreed with EPA’s decision to reject the option to select add-on control (cycl ones) as GACT for facilities that produce less than 50 tpd o f prepared feeds. The commenter points out that EPA determined that approximately 20 percent of existin g facilities already had cyclones installed, and that the agency estimated that the cost effectiveness of req uiring the remaining 80 percent to install controls would be around $1 million per ton of chromium and manganese compound emission reduction, $4,000 per ton of PM e mission reduction, and $20,000 per ton of PM2.5 reduction, and that the annual cost of installing and operating a cyclo ne at one of these facilities would be around $58,000 per year. The commenter recognizes that EPA performed an econ omic impact assessment, which indicated that these annua l costs could represent over 5 percent of the total annual sales for a small facility, and that EPA concluded that “ the adverse economic impacts do not justify a determina tion requiring cyclones for the small prepared feeds manufacturing subcategory.” The commenter states t hat, although this economic impact analysis is more inst ructive than mere reliance on cost effectiveness figures, t he 5 percent of total annual sales threshold is arbitrar y. The commenter states that EPA does not explain why the benefitsDRAFT –

DO NOTE CITE OR QUOTE 59 December 1, 2009 of further reductions in PM, PM2.5, manganese compo unds and chromium compounds, as well as other metal HAP emis sions, are not sufficient to justify the costs of the cont rols. The commenter stated their belief that the GACT pro vision’s requirement of cost considerations does not preclud e the

need to consider the environmental benefits of the proposed rule in determining whether those costs are justifi ed. Response : As noted by the commenter, we performed an economic impact assessment that indicated that the annual costs for fabric filters for bagging could represen t over 5 percent of the total annual sales for a facility wi th less than 5 employees. We strongly disagree that a deci sion to reject controls that would result in costs that rep resent 5 percent of the total annual sales is arbitrary. Th is 5 percent value was a direct calculation of the sma ll model plant cyclone costs divided by the average shipment s per facility for facilities with less than 5 employees. While each GACT decision includes a variety of factors to take into account, we generally consider costs in excess of 3 percent of sales to be significant and potentiall y economically damaging. Further, since we believe a ll of the facilities in the small facility subcategory ar e small businesses, we are even more sensitive to potential ly detrimental economic impacts. We also disagree tha t we didDRAFT –

DO NOTE CITE OR QUOTE 60 December 1, 2009

not consider the environmental benefits. For this option,

we estimated and considered the emission reductions of chromium, manganese, PM, and PM2.5. However, we de termined that these emission reductions are not justified gi ven the economic impacts. In conclusion, we believe our de cision to reject the option to require add-on controls for pelleting operations at prepared feed manufacturers with daily production rates of 50 tpd or less is justifi ed.

Comment : Two commenters recommended that, since the 50 tpd production level determines if emissions mus t be controlled from the pelleting and pellet cooling operations, this level should be related to the amo unt of feed pelletized and not the total amount of feed pr oduced by the entire facility. One of the commenters indi cated that they are aware of several prepared feeds manuf acturing facilities that do not pelletize feed, or that only pelletize a small percentage of the feed produced. Response : Under section 112(d)(1) of the CAA, EPA “may distinguish among classes, types, and sizes wi thin a source category or subcategory in establishing such standards”. As discussed at proposal (74 FR 36985) , we observed differences between prepared feeds manufac turing facilities based on production levels and subcatego rized the Prepared Feeds Manufacturing source category in toDRAFT –

DO NOTE CITE OR QUOTE 61 December 1, 2009 “small” and “large” facilities. The threshold used to distinguish between these subcategories was an aver age feed production level of 50 tpd. We then independently determined GACT standards for each subcategory. Th erefore, our subcategorization and GACT determinations were based on the separation of facilities according to total fee d production levels, not pelleting feed production. Since the change suggested by the commenter is inconsiste nt with our subcategorization decision and analyses, we ret ained the proposed definition of the small and large subcategories based on total feed production levels

. Comment : One commenter recommended that the 50 tpy threshold be on an annual, rather than daily, basis . The commenter said that this could be the production le vel in a calendar year or a rolling 12-month production leve l. The commenter points out that an annual production leve l of 13,000 tons per year would be equivalent to 50 tpd, assuming an operating schedule of 260 days per year . The commenter noted that the proposed daily rate did no t appear to have any special significance, as it was calcula ted as an average of annual production. The commenter bel ieved that an annual production rate would achieve the sa me objectives and would be easier than a daily product ion rate for facilities and for regulatory agencies to track

.DRAFT –

DO NOTE CITE OR QUOTE 62 December 1, 2009 Response : We did not incorporate the commenters’ suggestion to change the threshold to an annual bas is. In our determination of GACT, the data on the existenc e of controls were related to daily production levels. To

determine an annual threshold from these data would require an assumption regarding the number of days of opera tion per year. We do not believe that calculating an annual rate based on a “typical” production schedule is reflect ive of varying production schedules that exist in the indu stry. Therefore, the final rule maintains the daily produ ction level concept. Requiring owners and operators to m aintain annual production data and the number of operating days, and then dividing the annual production by the numb er of operating days is no more difficult or burdensome f or facilities or regulatory agencies than the approach recommended by the commenter.

Comment : Two commenters maintained that the pelleting cyclones would not be able to reach the proposed de sign efficiency of 95 percent for PM10. The commenters believed that this level of efficiency would not be attainab le under the conditions of the pelleting process. One comme nter suggested the efficiency requirement be changed to 95 percent for total PM (up to 35 micron). The commen ter included a chart from a cyclone manufacturer that s howedDRAFT –

DO NOTE CITE OR QUOTE 63 December 1, 2009 the efficiency in removal of PM10 by a cyclone esti mated at 90 percent. The commenter continued that this leve l would not be expected to be reached under the conditions of the pelleting process with its high moisture and high temperature conditions. The commenter stated that a second control device such as a baghouse or a wet scrubber would be necessary to reach a capture efficiency of 95 pe rcent

for PM10. Response : In the proposed rule, GACT for the pelleting operation was determined to be the use of a cyclone to control emissions of chromium and mangan ese. We did not specify GACT as a specific control efficien cy, concentration, or operating parameter. However, in order to establish criteria that represent a properly des igned, operated, and maintained control device, it was nec essary to establish requirements in the proposed rule on h ow the cyclone is designed and operated. Many respondents to the industry survey stated they use high efficiency cyc lones to control the pelleting operations. The result is re duced emissions to the air and the capture of lost produc t that can be returned to the manufacturing operation. As a follow up to the industry survey responses, we contacted an industry representative (Docket No. EP A-HQOAR-2008-0080-0010) that responded to our survey fo rDRAFT –

DO NOTE CITE OR QUOTE 64 December 1, 2009 several prepared feeds manufacturing facilities and asked about the level of efficiency that would be expecte d with high efficiency cyclones reported to be used to con trol the pelleting process. The representatives indicated t hat today’s high efficiency cyclones can be expected to get 99 percent control of particulates, while older one s can be expected to achieve efficiencies in the “mid 90 per cent” range. While background material gathered prior to proposal from vendors (Docket No. EPA-HQ-OAR-2008-0 080- 0034) show that high efficiency cyclones should be able to reach the proposed 95 percent efficiency level for PM10, we understand that the conditions of the pelleting pro cess are not optimum. We contacted additional cyclone manuf acturers after proposal, and some agreed with the commenters that cyclones designed to achieve 95 percent efficiency level for PM10 for pelleting operations are not available . All of those contacted indicated that many older cyclon es still being used in the industry would not meet the propo sed 95 percent PM10 design requirement. It was not our in tent to force prepared feeds manufacturers to replace older , well designed and properly operating cyclones with new h igh efficiency cyclones, particularly since the increme ntal emission reduction would be very low and the costs would be high (our estimates are that the capital cost of a newDRAFT –

DO NOTE CITE OR QUOTE 65 December 1, 2009 cyclone is between $50,000 to $100,000). The avail able information suggests that a 95 percent efficiency d esign requirement is achievable for total PM. Therefore, we have changed the criterion in the final rule to require cyclones designed to achieve a 95 percent efficiency level f or total PM, rather than for PM10.

Comment : A commenter recommended that the final rule provide explicit compliance alternatives to the req uirement to operate a 95 percent control efficient cyclone. The commenter cites that other area source NESHAP, such as the Nonferrous Foundry NESHAP (Subpart ZZZZZZ), establi sh a limit of either 99.0 percent control for PM or an e mission limit of 0.01 grains per dry standard cubic foot (g r/dscf). The commenter is concerned that having 95 percent c ontrol efficient cyclone as the only compliance option for pelletizing operations would unfairly penalize a fa cility that has a pelletizing process with low uncontrolle d emissions or a facility that uses other control equ ipment

to achieve emissions reductions. Response : The proposed rule required that emissions from pelleting operations be captured and routed to a cyclone designed to reduce PM10 emissions by 95 per cent. The format of the rule is an equipment standard, an d the 95 percent criterion is a design value, not an emis sionDRAFT –

DO NOTE CITE OR QUOTE 66 December 1, 2009 limitation. Therefore, there is no penalty for a f acility with low uncontrolled emissions, provided that they have a cyclone designed to achieve 95 percent reduction th at is operated and maintained properly.

Comment : A commenter requested clarification of whether PM or PM10 emissions is considered a surrog ate for HAP emission in the proposed rule. The commenter n otes that the proposed rule requires that pelletizing op erations at feed preparation facilities with daily productio n levels greater than 50 tpd be controlled by a cyclone desi gned to reduce PM10 emissions by 95 percent or greater, and that in several places in the preamble to the proposed rule that

EPA indicates that PM emissions will be considered the surrogate for chromium and manganese. The commente r asked whether PM or PM10 is the surrogate pollutant for t he proposed rule. The commenter points out that sever al other area source NESHAP consider PM to be the surrogate pollutant for HAP emissions such as Subpart ZZZZZZ (Aluminum, Copper, Nonferrous Foundries) and Subpar t ZZZZZ (Iron and Steel Foundries). The commenter recommen ds that EPA clarify in the final rule whether the surrogate pollutant is PM or PM10 and include a justification for the choice of surrogate. Further, the commenter recomm ends that, if EPA elects to use PM10 as the surrogate, E PADRAFT –

DO NOTE CITE OR QUOTE 67 December 1, 2009 evaluate the required control efficiency for the cy clone control equipment. Response : As stated in the preamble to the proposed rule, PM is the surrogate for chromium and manganes e emitted from this source category. However, when specifying compliance conditions, the proposed rule used the measure of collection efficiency of PM10. Due to other comments received (see above), the final rule uses PM as the metric for cyclone collection efficiency rather than PM10, which should remove any confusion about the surrogate.

Comment : A commenter notes that the proposed rule requires the owner of a cyclone at a feed preparati on facility with a daily production level of greater t han 50 tpd to keep a record from the cyclone’s manufacture r of the control efficiency. The commenter asks what EPA’s expectations are for facilities if the manufacturer ’s specifications are not available or do not show com pliance with the control efficiency? The commenter also as ked whether an owner or operator would have the option of demonstrating compliance with the rule by testing t he inlet/outlet concentrations of the cyclone for dete rmining the control efficiency. Finally, the commenter ask ed whether other particulate control devices, such as aDRAFT –

DO NOTE CITE OR QUOTE 68 December 1, 2009 baghouse or fabric filter, or control equipment in series, such as a cyclone and a baghouse, would be allowed? The commenter indicated that if these options are allow ed that

this should be made clear in the final rule. Response : The commenter asked what EPA’s expectations are for facilities in showing compliance with the r ule if the cyclone manufacturer’s design control efficienc y and operating and maintenance procedures are not availa ble. We acknowledge that this could be a problem, and have included in the final rule options for documenting that the cyclone is designed to achieve 95 percent PM reduction. Th e first option is to obtain certification from the manufact urer, as proposed. Under Option 2, the owner or operator co uld have a registered professional engineer or responsible o fficial certify that the cyclone is designed in a manner ca pable of achieving 95 percent or greater PM reduction and ke ep a record of the information used to make this determi nation. The third option is to conduct PM testing at the in let and outlet of the cyclone(s) to demonstrate that an eff iciency of 95 percent or greater PM reduction is actually b eing achieved.

Comment : Several commenters objected to the proposed requirement that emissions from bulk loading be red uced through the use of drop filter socks. Two of the commenters believe that this is too costly and shou ld not be considered as GACT. One of the commenters expla ined that, in order to meet the proposed requirements, o ne of their facilities would need to redesign and purchas e equipment for the entire bin and bin loading system and potentially redesign the entire mill, which could c ost

hundreds of thousands of dollars. Two commenters d isagreed with EPA’s claim that every facility uses drop filt er socks to reduce dust and the loss of product during the l oading of railcars and trucks. One of the commenters argu ed that EPA’s conclusion that every affected facility alrea dy uses drop filter socks to reduce dust and the loss of pr oduct during the loading of railcars and trucks contradic ts the background technical information in the docket, whi ch indicates that the use of drop filter socks was rep orted for around 70 percent of the plants. The commenter noted that they conducted a survey of 41 prepared feed manufacturing companies representing 306 plants to identifyDRAFT –

DO NOTE CITE OR QUOTE 70 December 1, 2009 how many facilities currently use drop filter socks . The commenter’s survey results were as follows:

1. The average number of loading-discharge points is 1 4.3 per facility

2. Only 53 percent of the responding industry faciliti es currently have drop filter socks installed at discharge points where prepared feed products are

loaded into trucks or railcars.

3. The estimated average cost to install each drop fil ter sock is $295.

4. The estimated average annual cost to maintain each drop filter sock is $215. The commenter indicated that, based on their survey results and the assumption that there would be approximatel y 6,300 affected facilities, the cost to install drop filte r socks at loading discharge points would be $12.5 million for the entire industry, with an annual cost of $9.1 millio n per year. The commenter notes the stark contrast in th ese estimates and EPA’s claim that the proposed require ment to install drop filter socks would not create addition al

associated costs for facilities. Three of the commenters point out other alternative methods that are equally effective in reducing emis sions and should be allowed. One commenter explained tha t manyDRAFT –

DO NOTE CITE OR QUOTE 71 December 1, 2009 facilities have discharge-loading points that alrea dy are designed to limit the distance between the feed-dis charge point and the conveyance, thereby minimizing potent ial dust

emissions. All three of these commenters note that many load-out operations are conducted in enclosed areas , which

minimizes emissions and eliminates the need for dro p filter socks. One of the commenters asked that, if the requirements did not apply to truck load-outs that occur inside a building, EPA should clarify this in the f inal

rule. Response : At proposal, we determined that filter drop socks (or drop filter socks, as we inadvertently us ed the terms interchangeably) represented GACT for bulk lo ading. As evident in the definition of “filter drop sock,” we intended that this term represent any “device at th e loadout end of a bulk loader that lessens fugitive emissions by containing the unloaded product within the device thus preventing windblown and drop caused fu gitive emissions.” We are confident in our assumption tha t every prepared feeds manufacturing facility uses some dev ice that meets the proposed broad definition of filter drop sock. However, these comments make it apparent that the i ndustry recognizes one specific technology as filter drop s ocks, or drop socks, and that it would not be accurate to as sumeDRAFT –

DO NOTE CITE OR QUOTE 72 December 1, 2009 that every facility utilizes this technology. Ther efore, in order to avoid confusion, we have removed the de finition of filter drop sock and revised the standard to req uire that, for the bulk loading process where prepared f eeds products containing chromium or manganese are loade d into trucks or railcars, a device must be used at the lo adout end of each bulk loader to lessen fugitive emission s. Examples of these devices include drop socks, flexi ble spouts, and any device that reduces the distance be tween the loading arm and the truck or railcar to a degre e that avoids dust. We believe it is important that these technologies be used for all bulk loaders, whether they are inside or outside. Therefore, this requirement app lies to all bulk loaders that load products containing chro mium or

manganese. 6. Bagging

Comment : One commenter disagreed with the decision to reject add-on controls for emissions from bagging operations based solely on the cost effectiveness o f installing and operating those controls. The comme nter explained that the Agency’s decision was made despi te the widespread use of these controls, as around 30 perc ent of the smaller facilities and over 90 percent of the l arger facilities controlled emissions from bagging. TheDRAFT –

DO NOTE CITE OR QUOTE 73 December 1, 2009 commenter points out that EPA did not disagree or r eject the notion that control options are appropriate or that the economic impacts are too great. Rather, the commen ter points out that the decision to reject the option w as based solely on the cost-effectiveness, and that no econo mic analysis was performed. The commenter indicated th at basing this GACT decision solely on cost effectiven ess was unlawful. The commenter stated that the Agency is not directed, under Section 112(d)(5), to set standards based on what the agency believes is cost effective. The commenter noted that the Agency themselves stated, “GACT must reflect the ‘methods, practices and techniques which are commercially available and appropriate for appl ication by the sources in the category considering economic impacts.’ 74 Fed. Reg. 36982 (quoting S. REP. NO. 101-228, at 171-72).” Response: We disagree with the commenter, as we believe that cost effectiveness is an appropriate m easure to consider in the evaluation of GACT, and that con sidering

cost effectiveness is not unlawful. We believe tha t by rejecting add-on controls for bagging operations be cause the cost effectiveness was “too high to be consider ed GACT,” clearly indicates that we concluded the econ omic impacts are too great. In the preamble to the prop osedDRAFT –

DO NOTE CITE OR QUOTE 74 December 1, 2009 rule (74 FR 36986), we presented the estimates for both sizes of facilities. For the facilities with daily production levels of 50 tpd or less, the estimates were over $7 million for the total capital costs and ove r $16 million per year for the total annual costs, result ing in

cost effectiveness estimates for these controls of around $255 million per ton of chromium and manganese redu ction, over $750,000 per ton of PM emission reduction, and $3.3 million per ton of PM2.5 reduction. For the facili ties with daily production levels greater than 50 tpd, t he estimates were over $10 million for the total capit al costs and over $13 million per year for the total annual costs, resulting in cost effectiveness estimates of around $37 million per ton of chromium and manganese reduction , over $100,000 per ton of PM emission reduction, and arou nd $500,000 per ton of PM2.5 reduction. Therefore, no changes

were made as a result of this comment. D. Inspections and Compliance Provisions

Comment : Two commenters stated that monitoring pressure drop would not be the best way to ensure t he proper functioning of the pelleting cyclones. The commenters noted that, due to high moisture conditi ons (always near dew point) of the dust laden air passi ng through the cyclones on the pellet cooler air syste m,DRAFT –

DO NOTE CITE OR QUOTE 75 December 1, 2009 accurately measuring the pressure drop is problemat ic. The commenters stated that moisture and particulates in the duct (especially those “upstream” of the collectors ) will constantly compromise the accuracy of the static pr essure indicating equipment. Secondly, the commenters sta te that the collectors are quite inaccessible and would req uire remote readouts, which add to the cost and maintena nce of this equipment. One commenter believed the best wa y to ensure the proper functioning of their collectors i s to simply monitor the amp-load of the fan. The commen ter states that if the amp-load on the fan motor stays within the proper range then the system is functioning pro perly. The commenter also stated that, in their operation, the cyclones are located between the cooler and the fan and the duct work is fully contained and sealed. According to the commenter, consequently, all the air that is discha rged from the fan has passed through the collectors. Th e commenter stated that, additionally, the fans on th eir cooler air systems are electrically interlocked wit h the pelleting system (i.e., the pellet mill feeder will not operate unless the fan is operating); consequently, if the pelleting system is operating, the fan will be oper ating and the continuous monitoring of the fan amps will ensure the collectors are operating in the proper range.DRAFT –

DO NOTE CITE OR QUOTE 76 December 1, 2009

One of these commenters believed that the cost to industry to install pressure-drop gauges and to mon itor cyclone pressure drop would be extremely high. Acc ording to the commenter, given the limited time provided b y EPA to respond to this proposed requirement, they were una ble to receive actual price quotes from vendors on the cos t to install a pressure-drop gauge on a cyclone at vario us types of facilities. The commenter anticipated that such prices could vary depending upon a facility’s equipment an d physical layout. However, according to the comment er, based upon best estimates from vendors, they believ ed that an average conservative cost to install a pressure- drop gauge is $1,500 to $2,000 per cyclone. This commen ter suggested that the rule be revised to include alter native management practices and equipment controls as foll ows: 1. Pellet cooling cyclones are to be operated inaccordance with the parameters authorized by airoperating permits issued by appropriate legal

authorities. 2. Pellet cooling cyclones are to be maintained and operated in accordance with the manufacturer’s

recommendations.DRAFT –

DO NOTE CITE OR QUOTE 77 December 1, 2009 3. Once per day, affected facilities are to perform a visual inspection of the operating cyclone and the discharge air stream to observe emissions. 4. Should an affected facility observe an emission discharge that is not in accordance with the parameters authorized within its air-operating perm it, corrective actions are to be taken immediately to correct the discharge and bring it into compliance with its air-operating permit. The details of such occurrences, if any, are to be recorded in the facility’s maintenance records as required by rule’ s recordkeeping and notification requirements. Response : We believe that it is necessary to have a reasonably frequent indication that the cyclones ar e operating properly. Cyclones are relatively simple devices and generally have no moving parts. A cyclone uses an induced draft fan to move the gas stream through th e device. These fans are sized to provide the maximu m inlet velocity possible for high separation without exces sive turbulence. The primary indicators of the performa nce of cyclones are the outlet opacity and inlet velocity. The commenter suggested the use of outlet opacity to monitor performance; however, monitoring outlet opa city would require that trained off-site contractors be used, orDRAFT –

DO NOTE CITE OR QUOTE 78 December 1, 2009 more likely, that individuals at the plant be train ed and certified in determining opacity using Method 9. W e have estimated that a single Method 9 test by an off-sit e contractor costs around $2,000. While the costs to train and certify on-site employees to perform these requ ired daily tests would result in costs less than $2,000 per day, we still believe that the cost of using outlet opac ity as an indicator of performance would be too high. The refore, we elected to require monitoring which provides an indication of inlet velocity. Pressure drop across the cyclone is a surrogate for inlet velocity, and, con trary to the commenters’ claims, it is an appropriate measur e to indicate proper operation of a cyclone. Many cyclo ne manufacturers link the design efficiency with a spe cific pressure drop. However, other parameters are appro priate surrogates for the inlet velocity. In particular, monitoring either inlet flow rate, inlet velocity, or fan amperage are acceptable alternatives to monitoring pressure drop. As a result of these comments, we have added

alternatives to the final rule that allow an owner or operator to monitor pressure drop on a daily basis, or monitor either the inlet flow rate, inlet velocity, or amperage load to the fan, on a daily basis to show that the cyclone is performing consistent with its designDRAFT –

DO NOTE CITE OR QUOTE 79 December 1, 2009 specifications. The commenter did not provide any information to support their estimated costs of mon itoring equipment. One of the commenters suggested that many of the compliance provisions be deferred to existing permi t requirements. We disagree with the commenter’s sug gested approach. As an initial matter, section 112(d)(5) requires

that the Administrator establish national emission standards. To assure compliance with these nationa l emission standards, EPA develops monitoring, record keeping and reporting requirements, as it did in this rule. Indeed, one of the reasons supporting EPA’s exempti on of the prepared feed manufacturing area source categor y from the requirements of title V is that this rule conta ins sufficient monitoring, recordkeeping and reporting requirements to assure compliance with the requirem ents of the final rule. Thus, section 112 contemplates not only

that EPA will establish national emission standards , but that EPA will establish appropriate monitoring, recordkeeping and reporting requirements to assure compliance with those requirements. Furthermore, t he monitoring and other compliance provisions in State permits can vary considerably, and some prepared feeds manufacturing facilities may not even have permits. If aDRAFT –

DO NOTE CITE OR QUOTE 80 December 1, 2009 source would like to use an alternative monitoring approach allowed by a state permit, it should follow the requirements of 40 CFR 63.8(f). Therefore, we reje ct the commenter’s suggestion to remove any specific monit oring requirements from the rule.

Comment : Two commenters expressed concern over the frequency of record keeping for the pelleting contr ol devices. One of these commenters suggested that we ekly, rather than daily, pressure drop readings would be adequate. This commenter stated that, while a mont hly maintenance check on the cyclone is a reasonable requirement, daily pressure drop readings are exces sive because the pressure drop readings would not be exp ected to vary widely. The commenter also noted that many cy clones are installed in areas that are not easily accessib le so daily checks can be time consuming to collect data that they describe as a “maintenance indicator.” The ot her commenter stated that weekly recording of readings would be adequate and that daily recordkeeping was “overkill ” (although the commenter provided justification for reduced recordkeeping specific to a baghouse rather than th e proposed requirement for a cyclone). Response : We proposed using the maintenance indicator of pressure drop in order to ensure that the cyclon es areDRAFT –

DO NOTE CITE OR QUOTE 81 December 1, 2009 operating correctly as an indicator of compliance w ith the rule that can be readily checked by an inspector. As discussed above, the final rule includes the option to daily monitor inlet flow rate, inlet velocity, pres sure drop, or fan amperage. By providing multiple optio ns to indicate compliance, we believe the facility will f ind an option that can be completed from an accessible are a. Daily readings of these parameters are considered appropriate because, while a cyclone may be a rathe r simple control device in terms of moving parts, the system of ductwork and fans impact the efficiency of the unit . Each cyclone is designed for a specific inlet velocity i n order to maximize the collection efficiency. We believe that daily checks are necessary to ensure the ductwork i s not entraining outside air and/or that the fan is opera ting in the designed manner. As a result, we have not chan ged the requirement for daily monitoring and recording of c yclone performance measures.

Comment : A commenter also asked that the rule specify which cyclone is expected to have a pressure drop g auge installed in cases where multiple cyclones are inst alled in a line. Specifically, would pressure drop monitori ng be required for the initial cyclone, subsequent cyclon es, or all cyclones?DRAFT –

DO NOTE CITE OR QUOTE 82 December 1, 2009 Response : The answer is dependent on the design reduction efficiency of the cyclones. If one cyclo ne in a series is designed to achieve 95 percent or greater PM removal, then monitoring would only be necessary fo r that one device. However, if the design efficiencies fo r all the individual cyclones in the series are less than 95 percent, but the combined design efficiency is 95 p ercent or greater, then the inlet flow rate, inlet velocit y, pressure drop, or fan amperage for all the cyclones would

need to be monitored.

Comment : One commenter recommended that the Agency consider revising the proposed monitoring to specif y that the pressure drop must be monitored at least once p er day when the cyclone is in operation

. Response : We agree with the concept of this comment. However, we want to make clear that the cyclone is required to be used at all times when the pelleting process is in operation. Therefore, the rule has been revised to state that monitoring of the cyclone operating parameters is required at least once per day when the pelleting p rocess is in operation.

E. Reporting and Recordkeeping Requirements

Comment : One commenter stated that §63.11619(e)(1) of the proposed rule indicated that facilities that do not addDRAFT –

DO NOTE CITE OR QUOTE 83 December 1, 2009 any materials containing chromium or manganese comp ounds are not subject to the rule. The commenter interpr eted

this to mean that facilities that do not use chromi um- or manganese-containing materials would be excluded fr om all aspects of the NESHAP, including the requirement to submit an Initial Notification. However, the commenter no ted that, during the August 4, 2009 webinar (Docket Ite m No. EPA-HQ-OAR-2008-0080-44), it was suggested that the se facilities would be required to submit an initial

notification. The commenter indicated that it seem s unnecessary to require submittal of initial notific ation from facilities that do not use chromium or mangane se compounds, and requested that EPA clarify whether t his report is required of these facilities. Response : The commenter’s interpretation is correct. Facilities that do not add any materials containing chromium or manganese to any product manufactured a t the facility are not subject to the rule, including the requirement to submit an initial notification.

Comment : One commenter recommended that the proposed requirement to submit an annual compliance certific ation report be omitted from the final rule. The comment er said that annual reporting is burdensome and difficult f or small businesses to do year after year. The commenter be lievesDRAFT –

DO NOTE CITE OR QUOTE 84 December 1, 2009 that annual reporting creates excessive paperwork f or the facility and the delegated authority with little

environmental benefit. The commenter also recommen ded that the monthly record certifying that a facility has c omplied with the dust minimization management practices be omitted, as they believe it is very excessive. Response : Provided that the facility is in compliance, this annual compliance certification re port only needs to indicate that compliance has been ach ieved. In the event that a noncompliance event has occurre d, this report will need to provide information about this event. We believe it is important that there is clear accountability regarding compliance with the regula tion, and we believe that this is best accomplished by ha ving a responsible official certify that the facility has complied with the requirements in the rule. We disagree wi th the commenter that this once per year report is difficu lt and overly burdensome. Therefore, the final rule has r etained the requirement to submit annual certification repo rts. However, we considered the commenter’s request regarding the monthly certifications and have deter mined that they are not necessary. We believe that accountability can be maintained via the annual certifications and required records. Therefore, th eDRAFT –

DO NOTE CITE OR QUOTE 85 December 1, 2009 proposed requirement to keep a monthly record certi fying compliance with the management practices was not ma intained

in the final rule.

Comment : One commenter pointed out that the proposed rule did not require a facility to keep records to show that it was below or above the 50 tpd production le vel that determines whether controls are required for emissi ons from the pelleting and pellet cooling operation. The co mmenter also noted that the rule did not explain what happe ns when a facility with a daily production level less than 50 tpd increases production such that they would have a da ily production level greater than 50 tpd. The commente r recommended that provisions be added to eliminate t hese

deficiencies. Response : We agree with the commenter, and added recordkeeping and reporting requirements related to the average daily feed production level. We also clari fied how this level is to be determined. The final rule spe cifies that the initial determination of the average daily feed production level is based on the one year period pr ior to the compliance date for existing sources, or the de sign rate for new sources. The final rule also requires that facilities with average daily feed production level s below 50 tpd report their initial average daily feed prod uctionDRAFT –

DO NOTE CITE OR QUOTE 86 December 1, 2009 level in their Notification of Compliance Status re port. These facilities would be required to maintain aver age daily feed production level records to demonstrate that they do not exceed the 50 tpd threshold in the futu re. At the end of each calendar year, the facility will be required to re-calculate the average daily feed pro duction level for the previous year. If the average daily feed production level exceeds 50 tpd, the facility would have to comply with the requirement to collect emissions fr om the pelleting and pellet cooling operations and route t hem to a cyclone by July 1 of that year. Prepared feed mill owners or operators with averag e daily feed production levels less than 50 tpd that elect to comply with the requirement to collect emissions fr om the pelleting and pellet cooling operations and route t he emissions to a cyclone would not be required to mai ntain production records.

F. Definitions

Comment : Three commenters suggested that the EPA establish definitions for chromium compounds and ma nganese compounds. One of the commenters suggested using c riteria consistent with that found within the Agency’s TRI reporting requirements, and noted that these regula tions state that: (1) chromium compounds and manganese co mpoundsDRAFT –

DO NOTE CITE OR QUOTE 87 December 1, 2009 are exempt from the TRI reporting requirements when the concentration of such chemicals is less than 1 perc ent of the total compound; and (2) such an exemption appli es whether the facility received or produced the compo und. One of the other commenters pointed out that, in ot her area source NESHAP, materials containing HAP are defined as materials that contain chromium in amounts greater than 0.1 percent by weight or manganese in amounts greater t han 1.0 percent by weight. The commenter cited the definit ion of "Material containing MFHAP" in §63.1522 (40 CFR Par t 63, Subpart XXXXXX) as an example. Response : The commenters are confusing two concepts. A “chemical compound” is a basic chemistry term to indicate a substance composed of two or more elements united chemically in definite proportions by mass. Theref ore, any chemical compound containing the element chromium w ould be a “chromium compound.” For example, chromic oxide, chromium trioxide, and potassium chromate are all c hromium compounds. Similarly, any compound containing the element manganese is a “manganese compound.” Manganese dio xide and manganese chloride are examples of manganese compou nds. In the CAA, “chromium compounds” and “manganese compou nds” are the listed HAP. We typically use the “compound” terminology to remain consistent with the CAA. The refore,DRAFT –

DO NOTE CITE OR QUOTE 88 December 1, 2009 any chemical compound that contains chromium or man ganese is considered a HAP. We do not believe that it is necessary to add language in the rule to explain th is standard chemistry terminology. However, we agree with the commenter that the addi tion of definitions of “a material containing chromium” and “a material containing manganese” are appropriate. As we have pointed out in several other area source rulemaking s, the CAA section 112(k) inventory was primarily based on the 1990 TRI, and that is the case for the Prepared Fee ds Manufacturing source category as well. The reportin g requirements for the TRI do not include de minimis concentrations of toxic chemicals in mixtures; ther efore, the CAA section 112(k) inventory would not have inc luded emissions from operations involving chemicals below these concentration levels. See 40 CFR 372.38, Toxic Chem ical Release Reporting: Community Right-To-Know (Reporti ng Requirements). Accordingly, the percentages noted a bove define the scope of the listed source category; the y are not exemptions. Therefore, we believe that it is also appropriate t o incorporate this into the prepared feeds manufactur ing area source NESHAP. Specifically, we have added the fol lowing

definitions to the final rule:DRAFT –

DO NOTE CITE OR QUOTE 89 December 1, 2009

A material containing chromium means a material that contains chromium (Cr, atomic number 24) in amounts greater than or equal to 0.1 percent by weight.

A material containing manganese means a material that contains manganese (Mn, atomic number 25) in amount s greater than or equal to 1.0 percent by weight. We also revised the applicability provisions in § 63.11619(a) to specify that the rule applies to prepared feeds manufacturing facilities that use a material containing chromium or a material containi ng manganese and is an area source of emissions of HAP

. Comment : One commenter suggested that the EPA add the following definition for prepared animal feeds: “a mixture of ingredients and supplements fortified with essen tial minerals, intended to be fed directly to animals to meet or exceed total daily nutrient requirements.” The com menter also suggested that the definition of prepared feed s manufacturing facility be changed to specify that t he feeds produced must be “fortified with essential minerals .” Response : As discussed earlier in section B, the prepared feeds area source category extends beyond those facilities manufacturing only products intended to be fed directly to animals. Additionally, this definition is not

consistent with the NAICS code that forms the basis forDRAFT –

DO NOTE CITE OR QUOTE 90 December 1, 2009 this source category. Therefore, we did not incorp orate the changes suggested by the commenter.

Comment : One commenter requested that drop filter sock should be defined and that it needs to specify the

materials of construction and how far into the rail car or truck it needs to extend. Another commenter recomm ended that the Agency amend the term “drop filter sock” t o “drop sock, since the device does not filter potential em issions in any manner.” Response : As discussed in section V.C.5, we have eliminated the use of the term “filter drop sock” i n the final rule. Therefore, this definition has been re moved. G. Impacts Assessment

Comment : One commenter believes that EPA’s estimated number of prepared feeds manufacturers affected by the proposed rule is inaccurately low. The commenter p oints out that EPA states that approximately 1,800 area-s ource prepared feed manufacturing facilities currently op erating add chromium compounds or manganese compounds to th eir products and therefore would be subject to the prop osed area source standards. In contrast, the commenter b elieves

that the actual number of affected facilities excee ds 6,300. The commenter notes that the FDA’s bovine spongiform encephalopathy inspection database curre ntlyDRAFT –

DO NOTE CITE OR QUOTE 91 December 1, 2009 lists more than 6,300 feed mills in which FDA has c onducted inspections. The commenter points out that the actu al number of facilities subject to the proposed rule h as a direct impact on the agency’s stated benefits and c osts of

the rule. Response : We agree that the number of facilities subject to the rule is a key component in the asses sment of impacts. Ideally, we would not only have an estima te of the number of facilities in a source category for w hich we are developing regulations, but we would also have a list of those facilities. During our information gather ing efforts, it was clear that the industry was not wel l represented in the two national emissions data base s (TRI and NEI) that we typically use to characterize an i ndustry and their emissions. We also did not identify any other source of information that would provide a list of specific prepared feed manufacturing facilities in the U.S. Therefore, we based our estimate of 1,800 prepared feed manufacturing facilities on the 2002 U.S. Economic Census of Manufacturers. Prior to proposal, we consulted with the commenter on this topic, and the commenter agreed t hat 1,800 was a reasonable estimate. However, we appre ciate

that the commenter has now obtained other informati on that they believe indicates that the number of facilitie s may beDRAFT –

DO NOTE CITE OR QUOTE 92 December 1, 2009 higher than originally estimated. We investigated the FDA inspections database mentioned by the commenter and found that this database includes many more types of faci lities than just prepared feed mills. The FDA website say s the following: “Inspections of renderers, feed mills, ruminant feeders, protein blenders, pet feed manufacturers, pet feed salvagers, animal feed distributors and transporter s, ruminant feeders, and others have been conducted to determine compliance with the BSE/Ruminant Feed regulations.” Clearly this includes many types of facilities that are not in the Prepared Feeds Manuf acturing area source category. Facilities in the Prepared Feeds Manufacturing Sour ce Category are classified under NAICS 311119, which i ncludes “establishments primarily engaged in manufacturing animal food (except dog and cat) from ingredients, such as grains, oilseed mill products, and meat products.” The pro posed applicability of the rule was taken directly from t his NAICS definition, except that it limited applicabil ity to

those animal feed manufacturers that use chromium o r manganese. The 2002 U.S. Economic Census of Manufa cturers reports 1,567 establishments under NAICS 311119. T he census reports 1,811 establishments under the broad er NAICS 31111. While NAICS 31111 likely includes establish mentsDRAFT –

DO NOTE CITE OR QUOTE 93 December 1, 2009 that would not be included in the source category, we chose to place our estimate of the number of prepared fee d facilities at 1,800 to be conservative. As noted a bove, we sought input on this estimate and the commenter dee med it as a “reasonable estimate” (Docket No. EPA-HQ-OAR-2 008- 0080-0010). The commenter did not provide any explanation why the

Census data were incorrect for these NAICS codes. The commenter also did not provide evidence that establ ishments counted under other NAICS codes would be subject to the rule. As discussed in section V.B, we revised the applicability provisions to ensure that it is clear that the rule only applies to the types of facilities th at formed the basis for the source category listing. Since this listing was based on NAICS 311119, and no evid ence has

been submitted that the Census information for NAIC S is incorrect, we did not change our estimate of the po pulation of prepared feed manufacturing facilities in the U. S.

Comment : One commenter pointed out that data reported within the TRI, which were used as a basis for EPA’ s baseline emission estimates, are not solely an indi cation of emissions to the atmosphere. The commenter stat ed that, by definition, the reported release may result from spilling, leaking, pouring, emptying, discharging,DRAFT –

DO NOTE CITE OR QUOTE 94 December 1, 2009 injecting, escaping, leaching, dumping, or disposin g of the reported chemical into the environment. Response : The commenter is correct that a variety of types of releases are reported in the TRI. However , for our analysis, we only used releases reported as “Fu gitive

Air Emissions” and “Point Source Air Emissions.” Therefore, we disagree with the comment, as these r eleases clearly represent an indication of emissions to the atmosphere.

Comment : One commenter expressed concerns about the methodology used to estimate emission levels of chr omium compounds, manganese compounds, and total PM. The commenter stated their belief that this analysis la cked a sound statistical basis, and that the baseline emis sion estimates and corresponding estimated potential emi ssion reductions used by EPA within its proposed rule are erroneous and do not support EPA’s proposed managem ent practices and equipment controls. In particular, the commenter believed that it was inappropriate to extrapolate the chromium compound and manganese compound emissions for the entire industr y based on average emission rates from only 22 facilities represented in EPA’s 2006 TRI. The commenter point ed out that this problem was exacerbated by the fact that only aDRAFT –

DO NOTE CITE OR QUOTE 95 December 1, 2009 fraction of these 22 facilities reported emissions of chromium or manganese compounds. Further, the comm enter also stated that facilities reporting the majority of these emissions produce trace mineral premixes subsequent ly used by other feed manufacturers, and that they do not h ave pelleting operations, which EPA identifies as the l argest emission source at prepared feed mills. With regard to the estimated PM emissions, the commenter indicated that they believe that the aver age PM

emission level calculated from the NEI was inaccura te. In particular, the commenter believes that the 70 faci lities in the NEI with PM emissions represent a number of the highest production volume feed manufacturers in the United States. Therefore, the commenter states that using the average PM emissions for these larger facilities significantly overestimates the PM emissions for th e entire industry. Response : The information questioned by the commenter were considered by EPA in the selection of GACT. A s discussed above in section V.D, This information di d not impact the decision to regulate chromium and mangan ese from the prepared feeds source category or the decision which emission sources to regulate. Further, the emissio nDRAFT –

DO NOTE CITE OR QUOTE 96 December 1, 2009 reductions estimated by this analysis were only one of the considerations that make up the GACT decision. With regard to the specific concerns offered by th e commenter, the technical memorandum describing the

estimation of baseline emissions discussed the lack of facility-specific emissions data for the prepared f eeds industry. Given this lack of data, the approach se lected was to develop “model plants” to represent the indu stry. The use of model plants with “average” parameters i s a sound technical approach that EPA has long used whe n facility-specific information is not available for the entire industry. Therefore, we reject the argument by the commenter that the use of average emission levels i s inappropriate. However, we do recognize the concerns of the commenters with regard to the specific average emis sion levels utilized and the manner in which they were c reated. For instance, the average chromium compound emissio n level was based on a single facility’s emissions in the 2 006 TRI, and the average manganese compound emissions level was based on emissions from eight facilities. The comm enter did not provide any suggestions on how to improve t he analysis using the existing or other readily-availa bleDRAFT –

DO NOTE CITE OR QUOTE 97 December 1, 2009 information. However, in light of the concerns, we reexamined the available data and the approaches used

. After this review, relatively significant changes were made to five specific areas of our impacts analysis . Each

of these is discussed below. There is a technical memorandum in the docket that discusses these chang es further and presents the detailed updated results. 1. Changes to Analyses Percentage of Industry in Small Facility Subcatego ry . The proposal analysis estimated the number of prepa red feed manufacturing facilities with average daily feed pr oduction values of 50 tpd or less based on information submi tted by the industry in response to an EPA questionnaire. Around 11 percent of the facilities responding to this questionnaire had daily production levels of 50 tpd or less. Following the completion of the baseline emi ssions and impacts analyses, EPA conducted an economic imp act analysis. As part of this analysis, EPA collected detailed

data from the 2002 Economic Census of Manufacturers that broke down the industry based on the number of empl oyees. This information suggested that the profile of the industry based on the industry questionnaire responses may h ave been biased slightly toward larger facilities (i.e., a l arger percentage of the industry would have average daily feedDRAFT –

DO NOTE CITE OR QUOTE 98 December 1, 2009 production rates of 50 tpd or less than originally estimated). Therefore, this new information was us ed, along with correlation between production and reven ues provided by a commenter, to reassess this profile. The revised analyses assume that 29 percent of the faci lities in the industry have average daily feed production levels of 50 tpd or less. Number of Facilities Emitting Chromium . In the proposal analysis, it was assumed that every facili ty in the industry added chromium-containing nutrients to their products. However, in response to follow-up questi ons asked by EPA on their public comments, the industry trade organizations stated that: “The use of chromium com pounds among feed manufacturers is not as prevalent as the use of manganese compounds. Until a recent FDA-approval fo r use in dairy feeds earlier this year, chromium compounds h ad been approved for use only in swine feeds. Only about 2 to 3 percent of feed mills in the U.S. use a chromium co mpound, and only two compounds, chromium proprionate and ch romium tripicolinate, are approved by FDA for use in swine feed.” Based on this information, the revised impacts anal ysis assumes that only 3 percent of the prepared feed manufacturing facilities in the United States use a nd emit

chromium.DRAFT –

DO NOTE CITE OR QUOTE 99 December 1, 2009 Facility Average Chromium and Manganese Emission

Rates . Because the national databases considered prior to proposal contained data for such a limited number o f prepared feed manufacturing facilities, a model pla nt approach was used to estimate nationwide emissions and impacts for the source category. This model plant approach used facility average emission levels from the 2006 Toxics Release Inventory (TRI) for chromium and manganese. The commenter criticized the development of average emi ssion

rates from such a limited data set. To broaden the data set, TRI data were obtained for every facility repo rting NAICS code 311119 and/or SIC 3048 for the years 199 0 through 2007. There were over 10,000 facilities re porting these NAICS/SIC codes over these 18 years, averagin g just over 570 facilities per year. On average, there we re 134 facilities reporting manganese emissions each year and 2 reporting chromium. These data were used to calcul ate new facility average manganese and chromium emission ra tes, which were used in the revised analyses.

Production Level To Calculate PM Emission Factor . In the proposal analyses, the facility average PM emis sion

rate from the 2002 NEI for emission sources after t he point in the process when chromium or manganese would be added was divided by the average production rate from theDRAFT –

DO NOTE CITE OR QUOTE 100 December 1, 2009 facilities that responded to the EPA questionnaire to obtain an emission factor in units of tons per year PM emissions per tpd production level. The commenter indicated that this average production level used, 177 tpd, was not representative of the facilities in the NEI . They “conservatively estimated that the average producti on that

occurred at those facilities listed in the 2002 NEI exceeded 500 tpd.” In the revised analysis, the PM emissions factor was calculated based on the produc tion level of 500 tpd provided by the commenter. Cyclone Efficiency for PM2.5 . The impacts analysis for the proposed rule assumed that cyclones would a chieve a 95 percent reduction efficiency for PM 2.5 . An efficiency chart provided by a commenter shows cyclone efficie ncies of approximately 30 percent for PM 2.5 . This value was used in the revised analysis. 2. Summary of Revised Results The results of the revised impacts analysis showed a decrease in the PM emissions and increases in the manganese, chromium, and PM2.5 emissions. The revi sed emissions levels prior to the implementation of thi s regulation are 8.2 tons per year of chromium, 195 t ons per year of manganese, around 11,000 tons per year of b oth PM

and PM2.5.DRAFT –

DO NOTE CITE OR QUOTE 101 December 1, 2009 The revised analysis also shows higher levels of chromium and manganese emission reductions and lowe r levels

of both PM and PM2.5 reductions. Since the costs w ere not impacted by the changes to the analyses, the cost

effectiveness of the controls were lower for the ch romium and manganese and higher for the PM and PM2.5. Cos t

effectiveness values are discussed further in the r evised impacts memo which is in the docket. Based on the comments, we did change the impacts, but none of th ese conclusions affect our choice of GACT. H. Title V Requirements

Comment : Several commenters agreed with the proposed title V permit exemption, noting such factors as th e adequacy of existing state programs to ensure compl iance, the additional economic and other burdens imposed b y title V permitting, and the lack of technical resources t o comply with permitting requirements for facilities that ar e mostly

small businesses. Response : We acknowledge the commenters’ support for the exemption from title V permitting requirements in t his

rule.

Comment : One commenter argued that the agency’s proposal to exempt the area source category from title V requirements is unlawful and arbitrary. The comment erDRAFT –

DO NOTE CITE OR QUOTE 102 December 1, 2009 states that section 502(a) of the CAA authorizes EP A to exempt area source categories from title V permitti ng requirements if the Administrator finds that compli ance with such requirements is “impracticable, infeasibl e or unnecessarily burdensome.” 42 U.S.C. section 7661a( a). The

commenter notes that EPA did not claim that title V requirements are impracticable or infeasible for th e source category it proposes to exempt, but that EPA instea d relied entirely on its claim that title V would be “unnece ssarily

burdensome.” Response : Section 502(a) of the CAA states, in relevant part, that: . . . [t]he Administrator may, in the Administrator ’s discretion and consistent with the applicable provi sions of this chapter, promulgate regulations to exempt one or more source categories (in whole or in part) from the requirements of this subsection if the Administrato r finds that compliance with such requirements is impractic able, infeasible, or unnecessarily burdensome on such cat egories, except that the Administrator may not exempt any ma jor source from such regulations. See 42 U.S.C. section 7661a(a). The statute plainly vests the Administrator with discretion to determine when it is appropriate to e xemptDRAFT –

DO NOTE CITE OR QUOTE 103 December 1, 2009 non-major (i.e., area) sources of air pollution fro m the requirements of title V. The commenter correctly no tes that EPA based the proposed exemptions solely on a deter mination that title V is “unnecessarily burdensome,” and did not rely on whether the requirements of title V are “impracticable” or “infeasible”, which are alternat ive bases for exempting area sources from title V. To the extent the commenter is asserting that EPA m ust

determine that all three criteria in CAA section 50 2 are met before an area source category can be exempted from title V, the commenter misreads the statute. The s tatute expressly provides that EPA may exempt an area sour ce category from title V requirements if EPA determine s that the requirements are “impracticable, infeasible or unnecessarily burdensome.” See CAA section 502 (emp hasis added). If Congress had wanted to require that all three criteria be met before a category could be exempted from title V, it would have stated so by using the word “and,” in place of “or”.

Comment : One commenter stated that, in order to demonstrate that compliance with title V would be “unnecessarily burdensome,” EPA must show, among ot her things, that the “burden” of compliance is unnecess ary. According to the commenter, by promulgating title V ,DRAFT –

DO NOTE CITE OR QUOTE 104 December 1, 2009 Congress indicated that it viewed the burden impose d by its requirements as necessary as a general rule. The co mmenter maintained that the title V requirements provide ma ny benefits that Congress viewed as necessary. Thus, i n the commenter’s view, EPA must show why, for any given category, special circumstances make compliance unnecessary. The commenter believed that EPA has no t made that showing for the category it proposes to exempt

. Response : EPA does not agree with the commenter’s characterization of the demonstration required for determining that title V is unnecessarily burdensom e for an area source category. As stated above, the CAA prov ides the Administrator discretion to exempt an area source c ategory from title V if he determines that compliance with title V requirements is “impracticable, infeasible, or unnecessarily burdensome” on an area source categor y. See CAA section 502(a). In December 2005, in a national rulemaking, EPA interpreted the term “unnecessarily burdensome” in CAA section 502 and developed a four -factor balancing test for determining whether title V is unnecessarily burdensome for a particular area sour ce category, such that an exemption from title V is appropriate. See 70 FR 75320, December 19, 2005 (“E xemption Rule”). In addition to interpreting the term “unnec essarilyDRAFT –

DO NOTE CITE OR QUOTE 105 December 1, 2009 burdensome” and developing the four-factor balancin g test in the Exemption Rule, EPA applied the test to cert ain area source categories. The four factors that EPA identified in the Exempti on Rule for determining whether title V is unnecessari ly burdensome on a particular area source category inc lude: (1) whether title V would result in significant improvements to the compliance requirements, includ ing monitoring, recordkeeping, and reporting, that are proposed for an area source category (70 FR 75323); (2) whet her title V permitting would impose significant burdens on the area source category and whether the burdens would be aggravated by any difficulty the sources may have i n obtaining assistance from permitting agencies (70 F R 75324); (3) whether the costs of title V permitting for the area source category would be justified, taking int o consideration any potential gains in compliance lik ely to occur for such sources (70 FR 75325); and (4) wheth er there are implementation and enforcement programs in plac e that are sufficient to assure compliance with the NESHAP for the area source category, without relying on title V pe rmits (70 FR 75326). 4

4 In the Exemption Rule, in addition to determining whether compliance with title V requirements would beDRAFT –

DO NOTE CITE OR QUOTE 106 December 1, 2009 In discussing the above factors in the Exemption Ru le, we explained that we considered on “a case-by-case basis

the extent to which one or more of the four factors supported title V exemptions for a given source cat egory, and then we assessed whether considered together th ose factors demonstrated that compliance with title V requirements would be ‘unnecessarily burdensome’ on the category, consistent with section 502(a) of the Act .” See 70 FR 75323. Thus, we concluded that not all of the four factors must weigh in favor of exemption for EPA to determine that title V is unnecessarily burdensome for a particular area source category. Instead, the facto rs are to be considered in combination and EPA determines whether the factors, taken together, support an exemption f rom title V for a particular source category.

The commenter asserts that “EPA must show . . . tha t the “burden” of compliance is unnecessary.” This is not, however, one of the four factors that we developed in the unnecessarily burdensome on an area source category , we considered, consistent with the guidance provided b y the legislative history of section 502(a), whether exem pting the area source category would adversely affect public health, welfare or the environment. See 72 FR 15254-15255, March 25, 2005. As discussed in the proposed rule and below, after conducting the four-factor balancing test and deter mining that title V requirements would be unnecessarily burdens ome on the area source categories at issue here, we examined w hether the exemption from title V would adversely affect publi c health, welfare and the environment, and found that it woul d not.DRAFT –

DO NOTE CITE OR QUOTE 107 December 1, 2009 Exemption Rule in interpreting the term “unnecessar ily burdensome” in CAA section 502, but rather a new te st that

the commenter maintains EPA “must” meet in determin ing what is “unnecessarily burdensome” under CAA section 502 . EPA did not re-open its interpretation of the term “unnecessarily burdensome” in CAA section 502 in th e July 27, 2009 proposed rule for the category at issue in this rule. Rather, we applied the four-factor balancing test articulated in the Exemption Rule to the source cat egory for which we proposed title V exemption. Had we sou ght to re-open our interpretation of the term “unnecessari ly burdensome” in CAA section 502 and modify it from w hat was articulated in the Exemption Rule, we would have st ated so in the July 27, 2009 proposed rule and solicited co mments on a revised interpretation, which we did not do. Accordingly, we reject the commenter’s attempt to c reate a new test for determining what constitutes “unnecess arily burdensome” under CAA section 502, as that issue fa lls outside the purview of this rulemaking. 5

5 If the commenter objected to our interpretation of the term “unnecessarily burdensome” in the Exemption Rule, i t should have commented on, and challenged, that rule. Any challe nge to the Exemption Rule is now time barred by CAA section 30 7(b). Although we received comments on the title V Exemption Rule during the rulemaking process, no one sought judicial review o f that rule.DRAFT –

DO NOTE CITE OR QUOTE 108 December 1, 2009 Furthermore, we believe that the commenter’s positi on that “EPA must show . . . that the ’burden’ of comp liance is unnecessary” is unreasonable and contrary to Congressional intent concerning the applicability o f title V to area sources. Congress intended to treat area sources differently under title V, as it expressly authoriz ed the EPA Administrator to exempt such sources from the requirements of title V at her discretion. There ar e several instances throughout the CAA where Congress chose to treat major sources differently than non-major s ources, as it did in CAA section 502. Moreover, although th e commenter espouses a new interpretation of the term ‘unnecessarily burdensome’ in CAA section 502 and a ttempts to create a new test for determining whether the requirements of title V are ’unnecessarily burdenso me’ for an area source category, the commenter does not exp lain why EPA’s interpretation of the term ‘unnecessarily bur densome’ is arbitrary, capricious or otherwise not in accord ance with law. We maintain that our interpretation of th e term ‘unnecessarily burdensome’ in section 502, as set f orth in the Exemption Rule, is reasonable.

Comment : One commenter stated that exempting a source category from title V permitting requirements depri ves both the public generally and individual members of the publicDRAFT –

DO NOTE CITE OR QUOTE 109 December 1, 2009 who would obtain and use permitting information fro m the benefit of citizen oversight and enforcement that C ongress plainly viewed as necessary. According to the comme nter, the text and legislative history of the CAA provide that Congress intended ordinary citizens to be able to g et emissions and compliance information about air toxi cs sources and to be able to use that information in enforcement actions and in public policy decisions on a state and local level. The commenter stated that Co ngress did not think that enforcement by states or other government entities was enough; if it had, Congress would not have enacted the citizen suit provisions, and t he legislative history of the CAA would not show that Congress viewed citizens’ access to information and ability to enforce CAA requirements as highly important both a s an individual right and as a crucial means to ensuring compliance. According to the commenter, if a source does not have a title V permit, it is difficult or impos sible — depending on the laws, regulations and practices of the state in which the source operates — for a member o f the public to obtain relevant information about its emi ssions and compliance status. The commenter stated that, l ikewise, it is difficult or impossible for citizens to bring

enforcement actions. The commenter continued that E PA doesDRAFT –

not claim — far less demonstrate with substantial e vidence — that citizens would have the same ability to obta in compliance and emissions information about sources in the category it proposes to exempt without title V perm its. The commenter also said that, likewise, EPA does not cl aim —

far less demonstrate with substantial evidence — th at citizens would have the same enforcement ability. T hus, according to the commenter, the exemption EPA propo ses plainly eliminates benefits that Congress thought necessary. The commenter claimed that to, justify i ts exemption, EPA would have to show that the informat ional and enforcement benefits that Congress intended tit le V to confer — benefits which the commenter argues are el iminated by the exemptions — are for some reason unnecessary with respect to the category it proposes to exempt. The

commenter concluded that EPA does not even acknowle dge these benefits of title V, far less explain why the y are unnecessary, and that for this reason alone, EPA’s proposed exemptions are unlawful and arbitrary. Response : Once again, the commenter attempts to create a new test for determining whether the requirements of title V are “unnecessarily burdensome” on an area s ource category. Specifically, the commenter argues that E PA does

not claim or demonstrate with substantial evidence thatDRAFT –

DO NOTE CITE OR QUOTE 111 December 1, 2009

citizens would have the same access to information and the same ability to enforce under these NESHAP, absent title V. The commenter’s position represents a significant r evision of the fourth factor that EPA developed in the Exem ption Rule in interpreting the term “unnecessarily burden some” in CAA section 502. For all of the reasons explained a bove, the commenter’s attempt to create a new test for EP A to meet in determining whether title V is “unnecessari ly burdensome” on an area source category cannot be su stained. Moreover, EPA’s interpretation of the term “unneces sarily

burdensome” in CAA section 502 is reasonable. EPA reasonably applied the four factors to the fact s of the category at issue in this rule, and the comm enter has not identified any flaw in EPA’s application of the four factor test to the area source category at iss ue here. Moreover, as explained in the proposal, we consider ed implementation and enforcement issues in the fourth factor of the four-factor balancing test. Specifically, th e fourth factor of EPA’s unnecessarily burdensome analysis p rovides that EPA will consider whether there are implementa tion and enforcement programs in place that are sufficient t o assure compliance with the NESHAP without relying on title V permits. See 70 FR 75326.DRAFT –

DO NOTE CITE OR QUOTE 112 December 1, 2009 In applying the fourth factor here, EPA determined that there are adequate enforcement programs in pla ce to assure compliance with the CAA. As stated in the pr oposal, we believe that state-delegated programs are suffic ient to assure compliance with the NESHAP and that States m ust have adequate programs to enforce section 112 requiremen ts and provide assurances that they will enforce the NESHA P before EPA will delegate the program. In addition, EPA re tains authority to enforce this NESHAP under the CAA. See 74 FR 36988. The commenter does not challenge the conclu sion that there are adequate state and federal programs in place to ensure compliance with and enforcement of the NE SHAP. Instead, the commenter provides an unsubstantiated assertion that information about compliance by the area sources with this NESHAP will not be as accessible to the public as information provided to a state pursuant to title V. The commenter does not, however, provide any inf ormation

that states will treat information submitted under these NESHAP differently than information submitted pursu ant to a title V permit. Even accepting the commenter’s assertions that it i s more difficult for citizens to enforce the NESHAP a bsent a title V permit, which we dispute, in evaluating the fourth factor in EPA’s balancing test, EPA concluded that thereDRAFT –

DO NOTE CITE OR QUOTE 113 December 1, 2009 are adequate implementation and enforcement program s in place to enforce the NESHAP. The commenter has prov ided no information to the contrary or explained how the ab sence of title V actually impairs the ability of citizens to enforce the provisions of these NESHAP. Furthermore, the fourth factor is one factor that w e evaluated in determining if the title V requirement s were unnecessarily burdensome. As explained above, we co nsidered that factor together with the other factors and det ermined that it was appropriate to finalize the proposed ex emption

at issue in this rule.

Comment : One commenter explained that title V provides important monitoring benefits, and, according to th e commenter, EPA assumes that title V monitoring woul d not add any monitoring requirements beyond those requir ed by the regulations for the category. The commenter sai d that in its proposal EPA proposed to require “continuous parameter monitoring and periodic recording of the parameter for the required control device to assure compliance. 74 Fed. Reg. at 36987.” The commenter further states that “EPA argues that its proposed standard, by including these requirements, provides monitoring ’sufficient to assure compliance’ with the requirem ents of the proposed rule. Id.” The commenter maintains th at EPADRAFT –

DO NOTE CITE OR QUOTE 114 December 1, 2009 made conclusory assertions and that the Agency fail ed to provide any evidence to demonstrate that the propos ed monitoring requirements will assure compliance with the NESHAP for the exempt sources. The commenter stated that, for this reason as well, its claim that title V requirements are “unnecessarily burdensome” is arbi trary and capricious, and its exemption is unlawful and a rbitrary and capricious. Response : As noted in the earlier comment, EPA used the four-factor test to determine if title V requir ements were unnecessarily burdensome. In the first factor, EPA considers whether imposition of title V requirement s would result in significant improvements to the complianc e requirements that are proposed for the area source categories. See 74 FR 36987. It is in the context o f this first factor that EPA evaluates the monitoring, recordkeeping and reporting requirements of the pro posed NESHAP to determine the extent to which those requi rements are consistent with the requirements of title V. Se e 70 FR

75323. The commenter asserts that “EPA argues that its proposed standard, by including these requirements, ‘provides monitoring sufficient to assure complianc e withDRAFT –

DO NOTE CITE OR QUOTE 115 December 1, 2009 the proposed rule.’ See Fed Red. 74 At 36987.” In the proposal, we stated: The proposed rule requires direct monitoring of control device parameters, recordkeeping that also may serve as monitoring, and deviation and other annual reporting to assure compliance with the requirement s. The monitoring component of the first factor favors title V exemption. For the management practices, th is proposed standard provides monitoring in the form o f recordkeeping that would assure compliance with the requirements of the proposed rule. Monitoring by m eans other than recordkeeping for the management practic es is not practical or appropriate. Records are required to ensure that the management practices are followed. The rule requires continuous parameter monitoring and p eriodic recording of the parameter for the required control device to assure compliance. The proposed rule requires t he owner or operator to record the date and results of perio dic control device inspections, as well as any actions taken in response to findings of the inspections. See 74 FR 36987. As the above excerpt states, we required continuous parameter monitoring and periodic records of the pa rameter for new and existing affected sources when the rule requires the installation of such controls. ThisDRAFT –

DO NOTE CITE OR QUOTE 116 December 1, 2009 monitoring is in addition to the recordkeeping that serves as monitoring for the management practices. The co mmenter does not provide any evidence that contradicts the conclusion that the proposed monitoring requirement s are sufficient to assure compliance with the standards in the

rule. Based on the foregoing, we considered whether title V monitoring requirements would lead to significant improvements in the monitoring requirements in the proposed NESHAP and determined that they would not. We belie ve that the monitoring, recordkeeping and reporting require ments in this area source rule can assure compliance. For the reasons described above and in the proposed rule, the first factor supports exempting this area source category from title V requirements. Assuming, for a rguments sake, that the first factor alone cannot support th e exemption, the four-factor balancing test requires EPA to

examine the factors in combination and determine wh ether the factors, viewed together, weigh in favor of exe mption. See 70 FR 75326. As explained above, we determined that the factors, weighed together, support exemption of the area source categories from title V.

Comment : One commenter believes that EPA cannot justify exempting the source from title V by assert ing thatDRAFT –

DO NOTE CITE OR QUOTE 117 December 1, 2009 compliance with title V requirements poses a “signi ficant burden.” According to the commenter, regardless of whether EPA regards the burden as “significant,” the Agency may not exempt a category from compliance with title V requ irements unless compliance is “unnecessarily burdensome.” Or in the commenter’s words, that “the compliance burden is especially great.” The commenter stated that in an y event, EPA’s claims about the alleged burden of compliance are entirely conclusory and could be applied equally to any major or area source category; therefore, the comme nter claims that EPA has not justified why this source c ategory should be exempt from title V permitting as opposed to any other category. Response : The commenter appears to take issue with the

formulation of the second factor of the four-factor balancing test. Specifically, the commenter states that EPA must determine that title V compliance is “unnecessarily burdensome” and not a “significant b urden,” as expressed in the second factor of the four-facto r balancing test. As we have stated before, we found the burden place d on the prepared feed manufacturing area source cate gory in complying with title V requirements is unnecessaril y burdensome when we applied the four-factor balancin g test.DRAFT –

DO NOTE CITE OR QUOTE 118 December 1, 2009 We did not re-open EPA’s interpretation of the term “unnecessarily burdensome” in this rule. As explain ed above, we maintain that the Agency’s interpretation of the term “unnecessarily burdensome,” as set forth in th e Exemption Rule and reiterated in the proposal to th is rule,

is reasonable. In applying the four-factor test, we properly analy zed the second factor, i.e., will title V permitting im pose a significant burden on the area source, and will tha t burden be aggravated by any difficulty that the source may have in obtaining assistance from the permitting agency. Se e 70 FR 75324. EPA found that the sources would have a sig nificant burden because we estimated that the average cost o f obtaining and complying with a title V permit in ge neral was $65,700 per source for a 5-year permit period. 74 FR 36988. In addition, EPA found that most of the sou rces affected by this rule are small businesses. Small

businesses often lack the technical resources to co mply with the permitting requirements and the financial resources needed to hire the necessary staff or out side consultants. EPA found that not only is the individ ual cost of permitting significant for this source category (i.e., $65,700) but also that the cost to this source cate gory with approximately 1,800 sources as a whole is sign ificant.DRAFT –

DO NOTE CITE OR QUOTE 119 December 1, 2009 Furthermore, given the number of affected sources i n this source category (i.e., approximately 1,800), it wou ld likely be difficult for them to obtain assistance f rom the permitting authorities. These specific factors for the affected sources alone justify that EPA has properl y exempted the source category from title V. However , as discussed in the proposal and above, EPA analyzed a ll of the four factors in making its determination that t hese sources should be exempt from title V permitting requirements; and we found that the totality of the se factors weighs heavily in favor of the exemption.

Comment : According to one commenter, EPA argued that compliance with title V would not yield any gains i n compliance with underlying requirements in the rele vant NESHAP (74 FR 36988). The commenter stated that EPA ’s conclusory claim could be made equally with respect to any major or area source category. According to the co mmenter, the Agency provides no specific reasons to believe that the additional informational, monitoring, reporting, certification, and enforcement requirements that ex ist in title V, but not in this NESHAP, would not provide additional compliance benefits. The commenter also stated that the only basis for EPA’s claim is, apparently, its beliefs that those additional requirements never co nferDRAFT –

DO NOTE CITE OR QUOTE 120 December 1, 2009 additional compliance benefits. According to the co mmenter, by advancing such argument, EPA merely seeks to ele vate its own policy judgment over Congress’ decisions reflec ted in the CAA’s text and legislative history. Response : The commenter takes out of context certain statements in the proposed rule concerning the fact ors used in the balancing test to determine if imposition of title V permit requirements is unnecessarily burdensome for the prepared feeds manufacturing area source category. The

commenter also mischaracterizes the first of the fo urfactor balancing test with regard to determining wh ether imposition of title V would result in significant improvements in compliance. In addition, the commen ter mischaracterizes the analysis in the third factor o f the balancing test which instructs EPA to take into acc ount any gains in compliance that would result from the impo sition of the title V requirements. First, EPA nowhere states, nor does it believe, tha t title V never confers additional compliance benefit s as the commenter asserts. While EPA recognizes that requir ing a title V permit offers additional compliance options , the statute provides that EPA must assess whether compl iance with title V would be unnecessarily burdensome to t he specific area sources at issue. For the source cate goryDRAFT –

DO NOTE CITE OR QUOTE 121 December 1, 2009 subject to this rulemaking, EPA concluded that requ iring title V permits would be unnecessarily burdensome. Second, the commenter mischaracterizes the first factor by asserting that EPA must demonstrate that title V will provide no additional compliance benefits. The first

factor calls for a consideration of “whether title V would result in significant improvements to the complianc e requirements, including monitoring, recordkeeping, and reporting, that are proposed for an area source cat egory.” Thus, contrary to the commenter’s assertion, the in quiry

under the first factor is not whether title V will provide any compliance benefit, but rather whether it will provide significant improvements in compliance requirements

. The monitoring, recordkeeping and reporting requirements in the rule are sufficient to assure compliance with the requirements of this rule, cons istent with the goal of title V permitting. For example, i n the Initial Notification, the source must include infor mation about the facility and its operations. The source m ust also certify how it is complying and that it has complie d with the required management practices and associated recordkeeping requirements. The source must furthe r certify that it has installed controls, if necessar y to meet the final standards and that it is monitoring theDRAFT –

DO NOTE CITE OR QUOTE 122 December 1, 2009 controls, as required by the final rule and keeping all necessary records regarding the inspections of the controls and any corrective actions taken as a result of see ing changes in the operation of the control equipment. See

section 63.11624 in the final rule. The source must also keep records and conduct inspections to document th at it is complying with the management practices finalized i n this

rule. See section 63.11624 in the final rule. The s ource must monitor and demonstrate cyclone performance ef ficiency and, if applicable, must begin corrective action an d record the specifics about the corrective action upon seei ng any deviation in the pressure drop or fan amperage in t he control equipment. The source must also submit devi ation reports to the permitting agency in the annual repo rt if there has been a deviation in the requirements of t he rule.

See section 63.11624 in the final rule. EPA believe s that these requirements in the rule itself provide suffi cient basis to assure compliance with the final emission standards, and does not believe that the title V requirements, if applicable to these sources, would offer significant improvements in the compliance of the s ources with the rule. Third, the commenter incorrectly characterizes our statements in the proposed rule concerning our appl icationDRAFT –

DO NOTE CITE OR QUOTE 123 December 1, 2009 of the third factor. Under the third factor, EPA ev aluates “whether the costs of title V permitting for the ar ea source category would be justified, taking into consideration any potential gains in compliance lik ely to occur for such sources.” Contrary to what the comme nter alleges, EPA did not state in the proposed rule tha t compliance with title V would not yield any gains i n compliance with the underlying requirements in the relevant NESHAP, nor does factor three require such a determ ination. Instead, consistent with the third factor, we consi dered whether the costs of title V are justified in light of any potential gains in compliance. In other words, EPA must view the costs of title V permitting requirements, considering any improvement in compliance above wha t the rule requires. EPA reviewed the area source categor y at issue and determined that the vast majority of the approximately 1,800 sources that would be subject t o the rule currently do not have a title V permit. As sta ted in the proposal, EPA estimated that the average cost o f obtaining and complying with a title V permit was $ 65,700 per source for a 5-year permit period, including fe es. See Information Collection Request for Part 70 Operatin g Permit Regulations, 72 FR 32290, June 12, 2007, EPA ICR Nu mber 1587.07. Based on this information, EPA determined thatDRAFT –

DO NOTE CITE OR QUOTE 124 December 1, 2009 there is a significant cost burden to the industry to require title V permitting for all the sources subj ect to the rule. In addition, in analyzing factor one, EPA found that imposition of the title V requirements offers no significant improvements in compliance. In consider ing the third factor, we stated in part that, “Because the costs of compliance with title V are so high, and the potent ial for gains in compliance is low, title V permitting is n ot justified for this source category. Accordingly, t he third factor supports the proposed title V exemptions for this area source category.” See 74 FR 36988. Most import antly, EPA considered all four factors in the balancing te st in determining whether title V was unnecessarily burde nsome on the prepared feeds manufacturing area source catego ry. EPA found it reasonable after considering all four fact ors to exempt this source category from the permitting requirements in title V. Because the commenter’s statements do not demonstrate a flaw in EPA’s appli cation of the four-factor balancing test to the specific f acts of the source category at issue here, the comments pro vide no basis for the Agency to reconsider its proposal to exempt this area source category from title V.

Comment : According to one commenter, “[t]he agency does not identify any aspect of any of the underlyi ngDRAFT –

DO NOTE CITE OR QUOTE 125 December 1, 2009 NESHAP showing that with respect to these specific NESHAP — unlike all the other major and area source NESHAP i t has issued without title V exemptions — title V complia nce is unnecessary.” Instead, according to the commenter, EPA merely pointed to existing state requirements and t he potential for actions by states and EPA that are ge nerally applicable to all categories (along with some small business and voluntary programs). The commenter sai d that, absent a showing by EPA that distinguishes the sour ces it proposes to exempt from other sources, however, the Agency’s argument boils down to the claim that it g enerally views title V requirements as unnecessary. The comm enter stated that, while this may be EPA’s view, it was n ot Congress’ view when Congress enacted title V, and a general view that title V is unnecessary does not suffice t o show that title V compliance is unnecessarily burdensome

. Response : The commenter again takes issue with the Agency’s test for determining whether title V is unnecessarily burdensome, as developed in the Exemp tion Rule. Our interpretation of the term “unnecessarily burdensome” is not the subject of this rulemaking. In any event, as explained above, we believe the Agency’s interpretation of the term “unnecessarily burdensom e” is a

reasonable one. To the extent the commenter asserts thatDRAFT –

DO NOTE CITE OR QUOTE 126 December 1, 2009 our application of the fourth factor is flawed, we disagree. The fourth factor involves a determinatio n as to whether there are implementation and enforcement pr ograms in place that are sufficient to assure compliance w ith the rule without relying on the title V permits. In dis cussing the fourth factor in the proposal, EPA states that prior to delegating implementation and enforcement to a stat e, EPA must ensure that the state has programs in place to enforce the rule. EPA believes that these programs will be sufficient to assure compliance with the rule. EPA also retains authority to enforce this NESHAP anytime un der CAA sections 112, 113 and 114. EPA also noted other fac tors in the proposal that together are sufficient to assure compliance with this area source. The commenter argues that EPA cannot exempt this ar ea source category from title V permitting requirement s because “[t]he agency does not identify any aspect of any of the underlying NESHAP showing that with respect to these specific NESHAP — unlike all the other major and ar ea source NESHAP it has issued without title V exempti ons — title V compliance is unnecessary” (emphasis added) . As an initial matter, EPA cannot exempt major sources fro m title V permitting. 42 U.S.C. 502(a). As for area sources , the standard that the commenter proposes – that EPA mus t showDRAFT –

DO NOTE CITE OR QUOTE 127 December 1, 2009 that “title V compliance is unnecessary” - is not consistent with the standard the Agency established in the Exemption Rule and applied in the proposed rule in determining if title V requirements are unnecessari ly burdensome for the source category at issue. Furthermore, we disagree that the basis for excludi ng the area source prepared feeds manufacturing catego ry from title V requirements is generally applicable to any source category. As explained in the proposal preamble and above, we balanced the four factors considering the facts and circumstances of the source category at issue in th is rule. For example, in assessing whether the costs of requ iring the sources to obtain a title V permit was burdenso me, we concluded that because the vast majority of the sou rces did not have a title V permit, the costs imposed on the source category were significant compared to the additiona l compliance benefits offered by the title V permitti ng

process.

Comment : One commenter stated that the legislative history of the CAA shows that Congress did not inte nd EPA to exempt source categories from compliance with ti tle V unless doing so would not adversely affect public h ealth, welfare, or the environment. See 74 Fed. Reg.36988. Nonetheless, according to the commenter, EPA does n ot makeDRAFT –

DO NOTE CITE OR QUOTE 128 December 1, 2009 any showing that its exemption would not have adver se impacts on health, welfare and the environment. The commenter stated that, instead, EPA offered only th e conclusory assertion that “the level of control wou ld remain the same” whether title V permits are requir ed or not 74 Fed. Reg. 36988-89. The commenter continued by stating that EPA relied entirely on the conclusory arguments advanced elsewhere in its proposal that compliance with title V would not yield additional compliance with the underlying NESHAP. The commente r stated that those arguments are wrong for the reasons give n above, and therefore EPA’s claims about public health, wel fare and the environment are wrong too. The commenter also s tated that Congress enacted title V for a reason: to assu re compliance with all applicable requirements and to empower citizens to get information and enforce the CAA. Th e commenter said that those benefits — of which EPA’s proposed rule deprives the public — would improve compliance with the underlying standards and thus h ave benefits for public health, welfare and the environ ment. According to the commenter, EPA has not demonstrate d that these benefits are unnecessary with respect to any specific source category, but again simply rests on its own apparent belief that they are never necessary. The commenterDRAFT –

DO NOTE CITE OR QUOTE 129 December 1, 2009 concluded that, for the reasons given above, the at tempt to substitute EPA’s judgment for Congress’ is unlawful and arbitrary. Response : Congress gave the Administrator the authority to exempt area sources from compliance wi th title V if, in his or her discretion, the Administrator “ finds that compliance with [title V] is impracticable, infeasible, or unnecessarily burdensome.” See CAA s ection 502(a). EPA has interpreted one of the three justif ications for exempting area sources, “unnecessarily burdenso me”, as requiring consideration of the four factors discuss ed above. EPA applied these four factors to the area s ource category subject to this rule and concluded that re quiring title V for this area source category would be unnecessarily burdensome. In addition to determinin g that title V would be unnecessarily burdensome on the pr epared feed manufacturing area source category, EPA also considered whether exempting the area source catego ry would adversely affect public health, welfare or the envi ronment. As explained in the proposal preamble, we concluded that exempting the area source category at issue in this rule would not adversely affect public health, welfare o r the

environment because the level of control would be t he same even if title V applied. We further explained in th eDRAFT –

DO NOTE CITE OR QUOTE 130 December 1, 2009 proposal preamble that the title V permit program d oes not generally impose new substantive air quality contro l requirements on sources, but instead requires that certain procedural measures be followed, particularly with respect to determining compliance with applicable requireme nts. The commenter has not provided any information that exe mption of this area source category from title V will adve rsely affect public health, welfare or the environment. VI. Impacts of the Final Standards We project that the baseline PM emissions from the estimated 1,800 facilities in the prepared feeds so urce category are approximately 11,000 tons/yr, with approximatley 11,000 tons/yr of PM 2.5 , 195 tons/yr of manganese and just over 8 tons/yr of chromium. We believe that management practices are already being impleme nted throughout the industry. Therefore, we do not expe ct any additional reductions in chromium compound, mangane se compound, or general PM emissions from these measur es. We estimate that the requirement to install cyclones o n the pelleting processes at the facilities with average daily feed production levels exceeding 50 tpd will result in emission reductions of around 1,100 tons/yr of PM, 100 tons/yr of PM 2.5 , and approximately 20 tons/yr of manganese and chromium emissions. While cyclones d o removeDRAFT –

DO NOTE CITE OR QUOTE 131 December 1, 2009 PM from the air stream, these solids are typically recycled back to the process. Therefore, we do not anticipa te any significant indirect or secondary air impacts of th is rule as proposed. In addition, we do not expect any non -air health, environmental, or energy impacts. As noted above, we believe all prepared feed manufacturing facilities already implement the prop osed management practices. Therefore, there will be no

additional costs for these measures. We estimate t hat the nationwide capital costs for the installation of cy clones on the pelleting cooling operations at the large fa cilities will be around $2.5 million. The associated annual costs are estimated to be just over $3 million/year. Many of the plants in this analysis have fewer tha n 500 employees, which is the threshold to be conside red “small” by the Small Business Administration. It i s currently estimated that under 2 percent of the fac ilities (26 facilities) in the category would potentially n eed to install new cyclones under the proposed regulatory alternative. The potential impact on the industry as a percentage of the value of shipments is small. Und er the proposed regulatory alternative, the largest potent ial impact is estimated as 0.96 percent of shipments fo r a subset of firms with an overall impact of 0.94 perc ent ofDRAFT –

DO NOTE CITE OR QUOTE 132 December 1, 2009 shipments for the industry as a whole. As a result , this action is not expected to have a significant impact on a substantial number of small entities or the economy as a whole, regardless of whether or not the firms in th e industry are able to pass along any increases in th eir

costs to the consumers. VII. Statutory and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and R eview This action is a “significant regulatory action” u nder the terms of Executive Order 12866 (58 FR 51735, Oc tober 4, 1993) because it may raise novel legal or policy is sues and is, therefore, subject to review under the Executiv e Order.

Th e recordkeeping and reporting requirements in the Gen eral Provisions are mandatory pursuant to section 114 of the CAA (42 U.S.C 7414). All information other than emissi ons data submitted to EPA pursuant to the information collec tion requirements for which a claim of confidentiality i s made is safeguarded according to CAA section 114(c) and the Agency’s implementing regulations at 40 CFR part 2, subpart

B. This NESHAP requires Prepared Feeds Manufacturing area sources to submit an Initial Notification and a Notification of Compliance Status according to the requirements in 40 CFR 63.9 of the General Provisio ns (subpart A). The annual burden for this informatio n collection averaged over the first three years of t his ICR is estimated to be a total of 27,000 labor hours pe r year at a cost of $1.7 million or approximately $980 per facility. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of informa tion unless it displays a currently valid OMB control nu mber.

DO NOTE CITE OR QUOTE 134 December 1, 2009 The Regulatory Flexibility Act generally requir es an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requi rements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule would not have a significant economic impact on a substantial number of

small entities. Small entities include small busin esses, small not-for-profit enterprises, and small governm ental jurisdictions. For the purposes of assessing the impacts of th is rule on small entities, small entity is defined as: (1) A small

small entities. We have determined that small entit y compliance costs, as assessed by the facilities' co st-tosales ratio, are expected to be less than 0.004 per cent for

the estimated 26 facilities that would not initiall y be in compliance. Although this final rule contains requ irements for new area sources, we are not aware of any new a rea sources being constructed now or planned in the nex t three years, and consequently, we did not estimate any im pacts

for new sources. Although this final rule will not have a significa nt economic impact on a substantial number of small en tities, EPA nonetheless has tried to reduce such impact. T he standards represent practices and controls that are common throughout the prepared feeds manufacturing industr y. The standards also require only the essential recordkee ping and reporting needed to demonstrate and verify complian ce. These standards were developed in consultation with small business representatives on the state and national level and the trade associations that represent small bus inesses.

The nationwide annualized cost of this rule for aff ected industrial sources is around $3 million/yr. Thus, this rule would not be subject to the requirements of se ctions 202 and 205 of the Unfunded Mandates Reform Act (UM RA). This final rule would also not be subject to the requirements of section 203 of UMRA because it cont ains no regulatory requirements that might significantly or uniquely affect small governments. The rule would not apply to such governments and would impose no oblig ations upon them.

E. Executive Order 13132: Federalism This action does not have federalism implications. It

will not have substantial direct effects on the Sta tes, on the relationship between the national government an d the States, or on the distribution of power and responsibilities among the various levels of govern ment, as specified in Executive Order 13132

. This rule does not impose any requirements on State and local governme nts. Thus, Executive Order 13132 does not apply to this final

rule.

G. Executive Order 13045: Protection of Children fr om Environmental Health and Safety Risks EPA interprets Executive Order 13045 (62 FR 198 85, April 23, 1997) as applying to those regulatory act ions that concern health or safety risks, such that the analysis required under section 5-501 of the Order has the p otential to influence the regulation. This action is not su bject to EO 13045 because it is based solely on technology performance. H.

Voluntary consensus standard s are technical standards (e.g., materials specifications , test methods, sampling procedures, and business practice s) that are developed or adopted by voluntary consensus sta ndards bodies. NTTAA directs EPA to provide Congress, thr ough OMB, explanations when the Agency decides not to us e available and applicable voluntary consensus standa rds. The rulemaking involves technical standards. Therefore, the Agency conducted a search to identif y potentially applicable voluntary consensus standard s. However, we identified no such standards, and none were brought to our attention in comments. Therefore, EP A has

J. Executive Order 12898: Federal Actions to Addres s Environmental Justice in Minority Populations and L owIncome Populations Executive Order 12898 (59 FR 7629, February 16, 1994) establishes federal executive policy on environment al justice. Its main provision directs federal agencie s, to the greatest extent practicable and permitted by la w, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.

EPA has determined that this final rule would not have disproportionately high and adverse human health or environmental effects on minority or low-income pop ulations because it increases the level of environmental pro tection for all affected populations without having any disproportionately high and adverse human health or environmental effects on any population, including any minority or low-income population.
