**RIN 2060**  **- AO60**  **New Source Performance Standards (NSPS) Review** 

**Under CAA section 111(b ) (**  **1 ) (** **B )**  **AGENCY:** Environmental Protection Agency (EPA) **ACTION:** Advanced Notice of Proposed Rulemaking **SUMMARY:** The purpose of this advanced notice of p roposed

rulemaking (ANPRM) is to request public comment on a proposed approach the EPA has developed to carry out the statutorily required periodic evaluation of the new s ource performance standards (NSPS) p rogram. Consistent with Executive Order 13563, “Improving Regulation and Regulatory Review,” issued on January 18, 2011 , this proposed approach will provide a streamlined process to ensure that public and private resources are focused on the rules that provide the greatest public health protection and are most likely to warrant revision to include current technology and eliminate obsolete or unnecessary requirements . By demonstrating the continued efficacy of the standards, the

agency will be able to fulfill its statutory requirement to review, and , if necessary , revise NSPS at a minimum ofPage 2 of 42

every 8 years . This ANPRM is part of the EPA’s effort to meet these statutory obligations . The agency is seeking comment on the overall approach to managing the NSPS program, in particular the criteria used to determine that

no review is needed for a subset of NSPS. **DATES:** Comments must be received on or before **[insert date 30 days after publication**  **in the FEDERAL REGISTER]** . **ADDRESSES:** The EPA has established a docket for this action under Docket ID No. EPA

The TTN provides information about various areas of air pollution control . Following signatu re, an electronic version of this document will be posted at www.epa.gov/ttn/oarpg under “Recent Additions.” The EPA has also created a technical support document (TSD) that provides supporting data and information for this ANPRM . The TSD will also be avai lable in the docket and on the TTN at www.epa.gov/ttn/oarpg under “Recent Additions.” **II. Background**  **Information** A . What is the NSPS program? Clean Air Act ( CAA ) s ection 111 requires the EPA Administrator to list categories of stationary sources if

s uch sources cause or contribute significantly to air pollution which may reasonably be anticipated to endanger public health or welfare . The EPA must then issue NSPS for such source categories. NSPS reflect the degree of emission limitation achievable through the application of the “best system of emission reduction” which the EPA determines hasPage 7 of 42

been adequately demonstrated . The EPA may consider certain costs and non

- air quality health and environmental impact s and energy requirements when establishing NSPS. Fo r a NAAQS pollutant or a Hazardous Air Pollutant (one listed under 112) , only new or modified or reconstructed stationary

sources are regulated . For other regulated pollutants , section 111(d) also requires states to set standards for existing sources. Under s ection 111(b), the EPA has the authority to define the source categories, determine the pollutants for which standards should be developed, identify the facilities within each source category to be covered, and set the emission level of the standards . Air pollutants currently regulated through various CAA section 111(b) standards include particulate matter (PM,PM2.5 ,PM10 ), nitrogen oxides (NOx ), carbon monoxide (CO), lead (Pb), volatile organic compounds (VOC), sulfur dioxide (SO 2 ), sulfuric a cid mist, fluorides, hydrogen sulfide, reduced sulfur compounds, total reduced sulfur, and landfill gas. CAA s ection 111(b ) ( 1 ) ( B ) generally requires the EPA to “at least every 8 years review and, if appropriate, revise ” NSPS . While conducting a review of existing NSPS, the EPA has also promulgated emission limits for pollutants not currently regulated for that source category and addedPage 8 of 42

additional affected facilities where appropriate . See, e.g., 75FR54970 (Sept. 9, 2010) 1 , 73FR35883 (June 24, 20 09) 2

. In addition, s ection 111 (b)(1)(B) also states that the EPA need not conduct this review if the EPA determines that reviewing an NSPS “is not appropriate in light of readily available information on the efficacy of such standard.” In setting or revising NSPS, CAA s ection 111(a)(1) provides that NSPS are to “reflect the degree of emission limitation achievable through the application of the best system of emission reduction which (taking into account the cost of achieving such reduction and any non - air quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.” The format of NSPS can vary from source category to source category (and even from facility type to facility type within an NSPS) including a numerical emission limit, a design standard, an equipment standard, or a work practice standard . In determining the best system

1EPA promulgated emission limits for nitrogen oxides and sulfur dioxide to the NSPS for Portland Cement plants which had previously only regulated particulate matter emissions. 2 In this rulemaki ng, EPA extended the coverage of the NSPS program to include additional affected facilities (e.g., delayed coking units) at a petroleum refinery.Page 9 of 42

of emission reduction , we typically conduct a review that identifies what emission reduction systems exist and how much they reduce air pollution in practice . This allows the EPA to identify potential emission limits . We evaluate each system in conjunction with cost of achieving such reduction and any non

- air quality health and environmental impact and energy requirements . The resultant standard is usually a numerical emissions limit, expressed as a performance level (i.e. , a rate -based standard or percent control ) . Although such standards are based on the effectiveness of one or more specific air pollution control systems , s ection 111 (b ) ( 5) provides that the EPA may not prescribe a particular technology that must be used to comply with a NSPS , except in instances where the Administrator determines it is not feasible to prescribe or enforce a standard of performance, as defined in section 111(h) . Upon promulgation, NSPS become national standards to which all new, modified, or reconstructed sources must comply. B . What is the status of the NSPS program? Since December 23, 1971, the Administrator has promulgated over 7 0 NSPS . These standards can be found in the Code of Federal Regulations (CFR) at 40 CFR part 60 . A list of all NSPS promulgated under the authority of CAA 111(b ) ( 1 ) ( B) is provided in Table 1, which includes thePage 10 of 42

promulgation date of the original standards and information on the most recent activity . Not all Federal Register actions indicate a review of the standard. In many cases the most recent action includes only minor amendments. For example, on October 17, 2000 , EPA made final minor amendments to numerous NSPS to include miscellaneous editorial changes and technical corrections to stationary testing and monitoring rules . See 65FR61768 through 65FR61792. Seventeen standards have been promulgated or revised within the last 8 years. In addition to those standards that are current within their review cycle, there are also multiple standards in different phases of the review process, including some standards that are in various stages of the litigation process. **Table 1**  **: List of**  **CAA §111(b ) (**  **1 ) (** **B) NSPS**  **3 NSPS**  **Subpart Date of**  **Promulgation (FR Citation)**  **Date of Most Recent Action**  **(FR Citation) 4**

C . What is the purpose of this notice? The purpose of this ANPRM is to request public comment

on a strategy for focusing reviews of the NSPS so as to maximize the public health and welfare benefits while ensuring that the resources of stakeholders, state and local agencies, and the federal government are used most efficiently and effectively . As part of this strategy, we are proposing criteria that would be use d to assess whether review of a particular NSPS is necessary during the review cycle . A listing of any NSPS for which we recommend not

8 Subpart K was superseded by subpart Ka and, thus, will not be reviewed or revised as all subpart K units that modify or reconstruct would be subject to subpart Ka.Page 18 of 42

revi ewing the standard based on these criteria (after considering comments to this notice) will be published in the Federal Register for public comment . Subsequent to this notice, all NSPS for which no review is warranted will be addressed with detailed technical information in a rulemaking proposal which will provide a further opportunity for public comment. If , after review of the public comments , EPA determines there is sufficient evidence that a full review of a standard is warranted, EPA would withdraw its no review conclusion for that standard . Otherwise by having demonstrated the continued effectiveness of an NSPS, the

agency will have fulfill ed its statutory obligations under 111(b) with respect to the 8

- year review requirement for that standard. In addition to fulfilling the mandate in CAA section 111(b)(1)(B), this process is also responsive to Executive Order 13563, “Improving Regulation and Regulatory Review,” issued on January 18, 2011, which directs each federal agency to “periodically review its existing significant regulations to determine whether any such regulations should be modified, streamlined, expanded, or repealed so as to make the agency's regulatory program more effective or less burdensome in achieving the regulatory objectives.”Page 19 of 42

The EPA’s proposed approach will allow this process to be made more efficient, so that both public and private

re sources can be focused where it makes the most sense. This strategy will reduce the resource burden to the government and stakeholders by eliminating the need for costly and time consuming reviews of certain standards , which are not expected to result in any environmental benefits. By determining which NSPS are not in need of review, the agency can then focus its resources on the remaining NSPS that are in need of revision (or at least a closer review to determine if revision is needed) . This notice is seeking comment on this proposed process and on the appropriateness of the proposed criteria for making a finding that a current NSPS does not need revi ew , and the application of those criteria in this evaluation of the NSPS program . Additionally, this notice is seeking comment on pertinent factors for the prioritization of NSPS to be reviewed , and potentially revised . **I I**  **I. Developing an NSPS Evaluation Strategy**  A . What are the goals of an evaluation strategy for the NSPS program? The primary goal of the NSPS strategy is to assist the

agency in fulfilling our statutory obligations in a streamlined process that ensures both public and privatePage 20 of 42

resources are focused on the rules that provide the greatest improvement in air quality, hea lth and welfare benefits and are most likely to warrant revi ew and revision to include current technology and eliminate obsolete or unnecessary requirements . At the same time, this focus on NSPS where greatest emission reductions can be achieved promotes better use of resources for industry, government agencies, environmental organizations, and all other stakeholders and participants in the regulatory review process. Additionally, in some instances, sources remain well controlled through other CAA programs, such as the national emission standards for hazardous air pollutants (NESHAP), that have provided similar, if not more stringent, regulations than what would be required through the revision of existing NSPS or implementation of new NSPS . We are also aware that, in some instances, an evaluation of NSPS may show the current requirements of the standard continue to meet the statutory requirements, and

no review is required. To optimize the air quality, health and welfare benefits of the NSPS program, the EPA is proposing to prioritize NSPS reviews such that those NSPS likely to bring about greater benefits to public health and welfare through air quality improvements, including environmentalPage 21 of 42

justice considerations, are revi ewed first . This prioritization is being done with consideration of multiple pollutants and processes, and synchronization of regulatory efforts as the primary driver, allowing the EPA to seek opportunities for increased air quality, health and welfare benefits, and greater administrative efficiency. B . Which NSPS do not need revi ew ? 1 . What is the EPA’s authority in determining whether to revi ew NSPS? As described previously, CAA section 111(b ) ( 1 ) ( B) requires the agency to review and, if appropriate, revise NSPS “at least every 8 years ”. Section 111(b ) ( 1 ) ( B) also gives the EPA authority to determine that reviewing an NSPS “is not appropriate in light of readily available information on the efficacy of such standard.” In most instances , the EPA has met the requirement of this section solely through formal review and revision (when deemed appropriate) of standards . We note that the majority of NSPS will be reviewed and considered for revision , as there are likely potential process improvements and technology advances that would alter the best system of emission reduction . In addition, a regular evaluation gives the EPA and the public the opportunity to consider whether requirements of aPage 22 of 42

particular NSPS are outmoded or no longer necessary . However, there are some NSPS where currently available information indicates that there are no potential gains to public health and welfare from a revi ew of the NSPS . When the continued efficacy of a standard is demonstrated, the

agency believes that u sing its authority to not devote resources to a rulemaking in these cases should also be considered as an option . All NSPS, including those that we determined do not need revi ew , will be subject to continual evaluation cycles, at least every 8 years . This notice presents three independent criteria that the agency believes can be used to demonstrate that review of NSPS would not provide emission reductions and associated air quality, health and welfare benefits. 2 . What are the criteria we believe are appropriate for determining the continued efficacy of NSPS ? We have identif ied three criteria that we have determined are appropriate to determine that revi ew of existing NSPS would not result in any health and welfare benefit s , and , thus , should not be revi ewed in the current review cycle . For this programmatic evaluation, we believe that in most cases NSPS that meet any one of these criteria do not need to be revi ewed . However, s everal possible conditions exist where a review might be appropriate, evenPage 23 of 42

if one or more of the criteria described above are met . For instance, i f there are emissions units not addressed by the existing NSPS, or if there has been stakeholder interest (e.g., environmental justice concerns) in updating an NSPS , then additional deliberat ion would be necessary before a decision not to review NSPS could be made . The first criterion focuses on the existence of updated or new control technology , which is used to inform a decision on the potential improvement in air quality or health and welfare benefits . We address the criterion with the following questions: Have there been advances in control technologies, process operations, design or efficiency improvements, or other factors that would lead to selection of a more stringent best system of emission reduction ? Are there available control s for pollutants or emission sources that were previously uncontrolled? If available information on control technology indicate s that revi ew of the standard would not result in more stringent emission limits or no greater level of control, and would not p rovide improvements in air quality and health and welfare benefit s, such standard would be listed as a potential candidate for no revi ew . There are certain source categories for which the information available from national databases (e.g., thePage 24 of 42

National Emissions Inventory), publicly available data, the EPA’s interaction with stakeholders from industries, environmental organizations, s tate, local, and Tribal governments on other rulemakings provides a strong technical basis to assess the availabi lity and economic feasibility of employing new control technologies, or design or efficiency improvements that could result in a revised best system of emission reduction determination . As an example , information developed under the CAA section 112 air tox ics program provides a significant amount of information on control technologies and pollution control measures for stationary sources . We specifically request comment on this criterion and the level of certainty required in making a finding that no

review is needed based upon an evaluation of readily available information that indicates no greater level of control would be expected at the conclusion of an evaluation under this criterion . The second criterion considers whether we anticipate any new, modified, or reconstructed sources within a source category, which would trigger applicability under the NSPS in question over the next 8 years . The predicted growth rate of an industry is used as an indicator of satisfying this criterion to the extent that no new, modified, orPage 25 of 42

reconstructed sources are anticipated over the next 8 years. It is possible to have a predicted negative growth rate, and still trigger NSPS applicability through modification or construction of new sources at a rate less than the closure rate of existing facilities . Some of the source categories covered by the NSPS represent very mature industries for which there is currently no growth, and this trend has existed for numerous years . For example, industries that rely on metal and mineral raw materials have tended to move out of the country to be closer to the sources of the raw materials . Copper mines in the U.S. have closed while new mines have opened in South America where there is greater access to raw materials . In other industries there have historically been multiple processes used to make some products, but cost, efficiency , and other forces have reduced the variety of processes in use . The result of these trends may be that NSPS address emission sources which are no longer in use , technology is outdated, and which likely will not be used in the future . Some other source categories include industries whose primary product has been superseded by a substitute product which serves the same purpose , but is produced using an entirely different process ( e.g., optical storage media as a substitute for magnetic tape ) and as a result there are noPage 26 of 42

expected new facilities or modifications of existing facilities. If this criterion were met, the rule would remain in effect for the remainder of the review cycle in the event that source s no longer in operation were to begin operation again . The agency is requesting comment on the appropriateness of this second criterion . Specifically, we request comment on the level of certainty require d in making a finding that no revi ew is needed based on the expectation that no new sources are to be constructed, reconstructed or modified in the source category within the current 8 year review cycle. The third criterion that may support a finding that revi ew is not necessary is the existence of other regulatory programs that are applicable to the same pollutants (either directly or as surrogates) and emission sources as the NSPS, such that a revi sion of the NSPS would result in best system of emission reduction requirements that are no more stringent than another applicable CAA requirement . When evaluating a standard by this criterion, we will also ensure that no inconsistencies or conflicts exist with these other rules. The intent of this criterion is to avoid revi ewing NSPS to adopt more stringent emission limitations that are already being achieved by anotherPage 27 of 42

regulation, and, thus , providing no or limited actual additional health and welfare benefit while redirecting resources from revision of standards where there are potential significant emission decreases . For example, the air toxics program implemented under CAA section 112(d) includes standards for major sources of toxic air pollutants based on Maximum Achievable Control Technology ( MACT ) . Although the CAA section 112(d) program regulates air toxics, rules under the program sometimes regulate the air toxics through the use of surrogates , such

as criteria pollutants ( PM and VOC ) . Section 112 establishes a minimum baseline or “MACT floor ” for standards , which, for existing sources in categories or subcategories with 30 or more sources, is based on the average emission limitation achieved by the best performing 12 percent of existing sources . For new sources, the standards for a source cat egory or subcategory cannot be less stringent than the emission control that is achieved in practice by the best controlled similar sources, as determined by the Administrator ( CAA section 112(d)(3)). The MACT floors form the least stringent regulatory opt ion the EPA may consider in the determination of MACT standards under section 112(d) for a source category. The EPA mustPage 28 of 42

also determine whether to control emissions ‘‘beyond

- the

floor,’’ after considering the costs, non

- air quality health and environmental impacts, and energy requirements of such more stringent control ( CAA section 112(d ) ( 2 )). MACT for new sources is the most stringent level of control identified under CAA s ection 112(d ). Therefore, where the EPA regulated air toxics through regulation of criteria pollutants as surrogates for the toxic pollutant(s), it would be expected in most cases that the level of the MACT standard would reflect a level that would meet or exceed the best system of emission reduction when the same pollutants are covered . Therefore, where the MACT and NSPS have comparable applicability ( e.g., covers the same emission sources and effectively controls the same pollutants) , the MACT would in many cases accomplish emissions reductions that would be equivalent to or greater than those achieved by a revised NSPS . In such cases, even if new facilities are constructed, the MACT would serve to achieve the level of control that would otherwise be achieved through updating the NSPS through the review pro cess . Under CAA section 112(d ) ( 6), the MACT standards are also subject to technology reviews every 8 years .Page 29 of 42 Another potential consideration for applying this criterion is the potential interaction with other CAA programs such as Best Available Control Te chnology (BACT) requirements for New Source Review (NSR ) . The CAA and corresponding implementing regulations require that a permitting authority conduct a BACT analysis on a case

-by

case basis, and the permitting authority must evaluate the amount of emiss ions reductions that each available emissions

- reducing technology or technique would achieve, as well as the energy, environmental, economic and other costs associated with each technology or technique. Based on this assessment, the permitting authority must establish a numeric emissions limitation that reflects the maximum degree of reduction achievable for each pollutant subject to BACT through the application of the selected technology or technique. BACT requirements must be at least as stringent as the best system of emission reduction set by the NSPS. The agency is requesting comment on the appropriateness of this third criterion . Although we are taking the position that this criterion is sufficient to make a finding that no review is needed, we solicit comment on whether interaction with other CAA requirements would make source categories meeting this criterion morePage 30 of 42

appropriate for a streamlined revi ew that incorporates the level of control achieved by the MACT into the NSPS, rather than a no revi ew determination . We also solicit comment on how interaction with the CAA ’s NSR programs (including the BACT, offset and netting regulations) should be accounted for in developing and implementing this criterion . In addition to the three detailed criteri a, s everal possible conditions exist where a review might be appropriate, even if one or more of the criteria described above are met . For instance, i f there are emissions units not addressed by the existing NSPS, or if there has been stakeholder interest (e.g., environmental justice concerns ) in updating an NSPS , then additional deliberat ion would be necessary before a decision not to review NSPS could be made . In addition, if there are pollutants that are not currently regul ated by an NSPS, but which the agency believes should be, we would likely take the opportunity to review the existing standards to see if they should be updated at the same time. If the NSPS is outdated , or could be made less burdensome without lessening the public health protection it provides , or conflicts with another applicable requirement, review might well be appropriate . These conditions have been considered in addition to a standard’s ability to meet one or more of the threePage 31 of 42

criteria as the agency developed the NSPS evaluation . In instances where one of the above conditions indicated the need for further consideration, those NSPS would be recommended to undergo a traditional review, with subsequent potential revision. In addition to taking comment on the general approach described in this notice, we also request comment on the following: (1) are the three criteria appropriate for determining whether NSPS should be revi ewed, (2) are there additional criteria that should be used to make a finding that NSPS remains efficacious and , therefore , revi ew of the standard is not needed , and (3) are there different criteria that should be used. In judging the appropriateness of criteria, commenters should also consider Executive Order 13563, which calls for periodic review of regulations “to make the agency's regulatory program more effective or less burdensome in achieving the regulatory objectives.” 3. How many NSPS are potential ly not in need of revi ew ? Of the NSPS requiring periodic review, the majority of NSPS would be subject to review and potential revision, and would not meet the criteria for establishing no revi ew as defined in this document . However, using the criteria outlined in this notice, the agency has identified aPage 32 of 42

limited number of NSPS as potential candidates to not undergo revi ew . These NSPS are listed in Table 2 along with the applicable criteria. **Table 2: NSPS potentially meeting cr iteria to not be**  **revi ew** **ed based on CAA 111(b ) (**  **1 ) (** **B) authority**

We are requesting comment on the list of NSPS provided in Table 2 as potentially not in need of revi ew . Specifically, we are soliciting comment on the appropriateness of NSPS not undergo ing revi ew based on the criteria indicated in Table 2 . We are also soliciting comment on any additional NSP S that should be considered as potentially not in need of revi ew based on the criteriaPage 34 of 42

provided in this document. For example, the following three NSPS may meet the third criteri on that revision of the NSPS would result in best system of emission reduction requirements that are no more stringent than another applicable CAA requirement (i.e., NESHAP) . However , a more detailed assessment would be necessary to ensure that the emission points covered by the other regulatory programs

are comparable to those covered by the NSPS :

 Large Appliances Surface Coating, Subpart SS

 Flexible Vinyl/Urethane Coating and Printing, Subpart FFF

 Surface Coating of Plastic Parts for Business Machines, Subpart TTT EPA is soliciting comments as to the extent to which the NESHAP sufficiently covers the above NSPS categories.

4 . What are examples of how the no revi ew criteria would be applied to NSPS categories? Evaluation of NSPS categories for which no revi ew is recommended may be influenced by comments received regarding the criteria as discussed in this document . However, we present as examples three NSPS categories that meet one or more of the criteria for which we believe , based on a preliminary evaluation, review of the standardsPage 35 of 42

is not necessary . These three categories are described below, along with a brief description of the reasons for their selection. A more detailed description of these three examples, including the rationale for recommending no revi ew , is provided in the TSD . All NSPS for which no revi ew is recommended, including the three examples presented in this ANPRM, will be presented , with detailed technical supporting documentation, in a proposal following this notice and will have further and full opportunity for public comment.

a. Primary Zinc Smelters NSPS example Primary Zinc Smelters is a source category for which currently available information indicates that there is no need at this time for revi ew of the NSPS (40 CFR 60 s ubpart Q) . Following an evaluation of the currently available technologies (i.e., double

- absorption on sulfuric acid plant ), we believe that a revised standard would not result in a more stringent level of control because no new control technologies, or design or efficiency imp rovements exist that would result in more stringent requirements 9

. We do not

9The criterion that no new control technology exists that would result in a more stringent requirements can be met when there is no new technology in exist ence at all or when there is no new technology that provides more effectivePage 36 of 42

find the current requirements of the rule to be outmoded or unnecessarily burdensome. We also do not expect any applicability of the standard over the next 8 years as no

new , modi fied , or reconstructed facilities subject to the NSPS are expected , due to changes in the types of processes typically used (i.e., there have been no new facilities since 1974, and only one facility remains in operation) . Furthermore , this category meets the criterion presented in this document that another CAA requirement would apply to any new , modified , or reconstructed facility with provisions that are effectively as stringent as what would likely be considered the best system of emission reduction under NSPS revi ew . Specifically, in complying with the NESHAP ( 40 CFR Part 63, Subpart GGGGGG ), the source must use control technologies that provide equal or more stringent SO 2 , PM, and opacity requirements than would result from revisions to the NSPS for both roaster and sinter processes . The agency believes that the Primary Zinc Smelters NSPS (subpart Q) meets all three of the criteria to not review a standard as described in this document . Therefore, the current standard would remain in effect until the next review cycle . controls. In the case of Primary Zinc smelters both conditions are met.Page 37 of 42

b. Magnetic Tape Production Operations NSPS example The second example of an NSPS category for which currently available information indicates that there is no need at this time for revi ew of the NSPS is Magnetic Tape Production Operations (40 CFR 60 subpart SSS), consisting of coating and mixing operation s at affected facilities . The agency concluded this because th is industry has been in continual decline for over 20 years . As a result, there is no growth anticipated in the industry over the next 8 years, and there are no anticipated new sources, reconstructions , or modifications that would trigger NSPS applicability . Consumer preferences and technology have changed such that the primary product of this i ndustry has been superseded by a substitute product (s) which serves the same purpose , but is produced using an entirely different process ( i.e. , optical storage media ) . On this basis, we believe that there would be no emission reductions and associated air quality and health and welfare benefits in revi ewing the best system of emission reduction for the magnetic tape production operations NSPS category . The new process for manufacturing optical storage media (e.g. , compact disks) is assessed under the NESHAP for Surface Coating of Plastic Parts and Products (40 CFR 6 3 subpart PPPP ) . Therefore, the current rule would remain in effectPage 38 of 42

for the remainder of the review cycle . In subsequent NSPS reviews, the EPA would consider whether rescinding the rule permanently is an appropriate action in accordance with E.O. 13563 . c . Graphic Arts Industry/ Publication Rotogravure Printing NSPS example The third example of an NSPS category for which currently available information indicates that there is no need at this time for revi ew of the applicable NSPS is Graphic Arts Industry/ Publication Rotogravure Printing (40 CFR 60 subpart QQ) . In accordance with criteri on 3, the NESHAP (40 CFR subpart KK) for Printing and Publishing is significantly more stringent than the NSPS under subpart QQ . The NESHAP recently went through the EPA’s Risk and Technology Review (RTR) process and no additional technology standards were adopted pursuant to CAA section 112(d ) ( 6) . Only two new facilities have been built in the past 15 years since the NESHAP was promulgated in 1996 . Both of these facilities placed their presses in permanent total enclosures using carbon absorbers’ to achieve very ef ficient solvent recovery . As part of the EPA’s RTR, it was determined that no new advancements in practices, processes or control technologies beyond those in place at the two new facilities were identified . The BACT levelPage 39 of 42

control at the two new fa cilities is representative of current industry practice and is state of the art technology, and a revised best system of emission reduction for the solvent recovery practice listed in the NSPS would not be more stringent . Under criteri on 2, there has been almost no growth in the industry in the past decade . The number of publication rotogravure printing facilities has declined from 27 to under 20 in the last 10 years . Only two facilities have been built in the last 15 years . No new facilities are anticipated during the next 8 year review cycle . Therefore, we do not expect applicability of the NSPS in the foreseeable future . Therefore, we believe no additional emission reductions would be achieved from a revision to the current standard . Thus the agency believes that the Publication Rotogravure Printing NSPS (subpart QQ) meets the criteria to not revi ew as described in this document . Detailed evaluations of the Primary Zinc Smelters source category , the Magnetic Tape Production Operations source category , and the Graphic Arts Industry/ Publication Rotogravure Printing source category can be found in the TSD . Following comment on this notice, more detailed analyses will be completed for other NSPS that meet one orPage 40 of 42

more of the crite ria listed in this document . The EPA is seeking comment on the appropriateness of the application of the proposed criteria as shown in these three examples . We are also seeking comment on any additional independent criteria that could be used in making a determination to not revi ew NSPS. C . NSPS Potentially in Need of Revi ew After identifying those NSPS that do not currently need revi ew , the focus of the NSPS strategy will be on reviewing, and potentially revising, those remaining standards as required by the statute. This will be done through prioritization of NSPS based on multi

-pollutant and sector -based 10 approache s . The benefit s of multi

-pollutant and sector

-based analyses and approaches include the ability to identify optimal s trategies that consider feasibility, costs, and benefits across multiple pollutant types

– criteria, toxics , and others . We intend to prioritize NSPS in need of a review based on a number of different criteria. Possible prioritization criteria would include the types and magnitude of

10A s ector -based approach is based on integrated assessments that consider multiple pollutants in a comprehensive and coordinated manner to manage emissions and CAA requirements. ( National Emission Standards for Hazardous Air Pollutants from the Portland Cement Manufacturing Industry and Standards of Performance for Portland Cement Plants; August, 2010.)Page 41 of 42

emissions, population exposure, trends in industry growth, advances in control measures and technologies , level and accuracy of monitoring required by the existing standards, expected NSPS applicability, ability to synchronize NS PS review with other CAA requirements ( e.g., RTR under CAA sections 112(f) and 112(d ) ( 6)), and availability of relevant information . **IV. Request for Comment and Next Steps** As described throughout this notice, the EPA is soliciting comments to develop an evaluation plan for the NSPS program . We also encourage readers to submit other comments and supporting data that could help us further improve NSPS review strategies . T o ensure a well balanced response and develop the best possible product, we encourage the submittal of both comments offering suggestions and changes and those supporting the strategies included in this ANPRM . **V. Statutory and Executive Order Reviews** Under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993), this is a “significant regulatory action” because we expected this action to raise novel legal or policy issues . Accordingly, the EPA submitted this action to the Office of ManagementPage 42 of 42 New Source Performance Standards (NSPS) Review Under CAA S ection 111(b ) (1 ) (B) and Budget (OMB) for review under Executive Order 12866 and 13563 (76 FR 3821, January 21, 2011) and any changes made in response to OMB recommendations will be documented in the docket for this action . Because this action does not propose or impose any requirements, and instead seeks comments and suggestions for the agency to consider in possibly developing a subsequent proposed rule, the various statutes and Executive Orders that normally apply to rulemakings do not apply in this case . Should the EPA subsequently determine to pursue a rulemaking, the EPA will address the statutes and Executive Orders as applicable to that rulemaking. **List of Subjects in 40 CFR Part 60** Environmental protection, Air pollution control, Intergovernmental relations, Reporting and recordkeeping requirements.
