Following that action, the Administrator received petition[s] for reconsideration as well as identified some issues that warrant further opportunity fo r public comment. In response to the petition[s], the EPA is reconsidering and requesting comment on several provisions of the final new source performance standards and emission guidelines for commercial and industrial solid waste incineration units.*** E.O. 12866 and 13563 Review

- Hazardous Secondary Materials rule. Originally promulgated on March 21, 2011, the Non - Hazardous Secondary Materials rule provides the standards and procedures for i dentifying whether Non
- Hazardous Secondary Materials are solid waste under the Resource Conservation and Recovery Act when used as fuels or ingredients in combustion units. The purpose of these proposed amendments is to clarify several provisions in order to implement the Non
- Hazardous Secondary Materials rule as the Agency originally intended. **DATES:** Comments must be received on or before [ INSERT THE DATE 60 DAYS AFTER THE DATE OF PUBLICATION OF THE PROPOSED RULE IN THE FEDERAL REGISTER ].

– Do Not Cite, Quote, or Release During Review *** Page 17 of 382 On December 1, 2000, the EPA promulgated NSPS and EG for CISWI units (60 FR 75338), hereinafter referred to as the 2000 CISWI rule. On January 30, 2001, the Sierra Club filed a petition for review in the Court challenging the EPA’s final CISWI rule. On August 17, 2001, the EPA g ranted a Request for Reconsideration, pursuant to CAA section 307(d)(7)(B), submitted on behalf of the National Wildlife Federation and the Louisiana Environmental Action Network, related to the definition of commercial and industrial solid waste incinerat ion unit and commercial or industrial waste in the EPA’s CISWI rulemaking. In granting the petition for reconsideration, the EPA agreed to undertake further notice and comment proceedings related to these definitions. On September 6, 2001, the Court entere d an order granting the EPA’s motion for a voluntary remand of the CISWI rule, without vacatur. The EPA request ed a voluntary remand of the final CISWI rule to address concerns related to the EPA’s procedures for establishing MACT floors for CISWI units in light of the Court’s decision in Cement Kiln Recycling Coalition v. EPA , 255 F.3d 855 (DC Cir. 2001)(Cement Kiln ). Neither the EPA’s granting of the petition for reconsideration, nor the Court’s order granting a voluntary remand, stayed, vacated or otherwise influenced the effectiveness of the 2000*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 18 of 382 CISWI rule. Therefore, the remand order had no impact on the impleme ntation of the 2000 CISWI rule. On February 17, 2004, the EPA published a proposed rule (CISWI Definitions Rule) soliciting comments on the definitions of “solid waste,” “commercial and industrial waste,” and “commercial and industrial solid waste inciner ation unit”. On September 22, 2005, the EPA published in the Federal Register the final rule reflecting our decisions with respect to the CISWI Definitions Rule. The rule was challenged and, on June 8, 2007, the Court vacated and remanded the CISWI Definit ions Rule. In vacating the rule, the Court found that CAA section 129 unambiguously includes among the incineration units subject to its standards, any facility that combusts any solid waste material, subject to four statutory exceptions. While the Court

vacated the CISWI Definitions Rule, the 2000 CISWI rule remains in effect. On March 21, 2011, the EPA promulgated revised NSPS and EG for CISWI units (76 FR 15704). That action constitutes the EPA’s response to the voluntary remand of the 2000 CISWI rule and to the 2007 vacatur and remand of the CISWI Definitions Rule. In addition, the EPA addressed the 5
- year technology review that is required under CAA section 129(a)(5). Following that action, the Administrator received petition[s] for reconsideration as well*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 19 of 382 as identified some issues that warrant further opportunity for public comment. In response to the petition[s], the EPA is reconsidering and requesting comment on several provisions of the final new source performance standards and emission guidelines for commercial and industrial solid waste incineration units. 2. How is the definition of solid waste addressed in the final CISWI rule? The RCRA definition of solid waste is integral in defining the CISWI source category. The EPA defines the NHSM that are solid waste under RCRA in the final “Identification of Non
Hazardous Secondary Materials That Are Solid Waste” Rulemaking. In an action parallel to the March 21, 2011, final CISWI rule, the EPA promulgated a final rule that identifies the standards and procedures for identifying whether NHSM are or are not solid waste when used as fuels or ingredients in combustion units. That action, here inafter referred to as the “2011 NHSM final rule,” is relevant to the final CISWI rule because some ERUs and waste -burning kilns combust, in their combustion units, secondary materials that are solid waste under the 2011 NHSM final rule. Commercial and industrial units that combust solid waste are subject to standards issued pursuant to CAA section 129, rather than to standards issued pursuant to CAA section 112*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 20 of 382 that would otherwise be applicable to such units (e.g., boilers, process heaters and cement kiln s). 3. What is the relationship between this rule and other combustion rules? These amendments address the combustion of solid waste materials (as defined by the Administrator under RCRA in the concurrent Non - hazardous Solid Waste Definition Rulemaking) in combustion units at commercial and industrial facilities. If an owner or operator of a CISWI unit permanently ceases combusting solid waste, the affected unit would no longer be subject to this regulation under CAA section 129. Section 112 rules of the CAA, applicable to boilers and process heaters at major sources and boilers at area sources, would apply to subject boilers and process heaters that do not combust solid waste. Boilers and process heaters that combust solid waste are subject to CISWI as ERUs . EPA has also finalized revised CAA section 112 NESHAP from the Portland Cement Manufacturing Industry (75 FR 21136, September 9, 2010). Cement kilns combusting solid waste are waste -burning kilns subject to CISWI, not the otherwise applicable NESHAP. B.

– Do Not Cite, Quote, or Release During Review *** Page 21 of 382 their petitions for reconsideration and the issues identified by the EPA in the March 21, 2011, notice of reconside ration. These provisions are: 1) revision of the subcategory of ERUs; 2) establishment of limitations on fuel switching provisions; 3) revision of the definition of cyclonic burn barrels; 4) establishment of the procedures for providing an affirmative defe nse for malfunction events; 5) revisions to the carbon monoxide monitoring requirements; 6) establishment of a full
load stack test requirement for CO coupled with continuous oxygen monitoring for CISWI units; and 7) establishment of a definition of “homogeneous waste” in the CISWI rule. The EPA is also proposing certain revisions, which are: 1) revised emission limits for the waste
-burning kiln and ERU subcategories to reflect updated inventories and additional data, 2) the removal of continuous CO monitor ing with CO CEMS requirements, 3) the removal of oxygen correction requirements for CO emission limits for ERUs during periods of startup and shutdown, and 4) the replacement of continuous PM monitoring for ERUs greater than 250 MMBtu/hr design heat input capacity with continuous parameter monitoring system requirements. The EPA is taking comment on those revisions .

Energy Recovery Units In the final rule, we established separate subcategories based on the types of fuels and wastes ERUs were designed to burn. Energy Recover Units (i.e., units that would be boilers and process heaters but that they combust solid waste) designed to burn gaseous fuels and liquids that are solid waste were included in one primary subcategory, and the other primary subcategory was for units designed to burn solid fuels or predominantly non
- coal solid materials. The soli d fuel ERU subcategory was further divided into separate subcategories for*** E.O. 12866 and 13563 Review

Petitioners have contended that they did not have adequate opportunity to comment on the ERU subcategories presented in the final rule. Some have suggested that all nine emission limits should be divided between coal and biomass ERUs, instead of only having different limits for CO, NOx and SO 2 . We are granting reconsideration of our subcategorization approach for ERUs and are also proposing to divide emission limits for PM, Cd, Pb and D/F between coal and biomass units. The generation of PM is affected by the combustor design and operation. Therefore, design differences between biomass and coal ERU units have an impact on the generation of PM. We also are separating Cd and Pb with PM primarily due to the observation that these metals typically precipitate onto PM and are controlled along with PM. Finally, while D/F formation depends to some extent on the amount of chlorine available in the combustion gases, it is also affected by the amount of time the chlorine and hydrocarbon materials remain within a particular temperature range. The time gases remain in this range is a function of the combustor design, therefore, we have proposed separate limits for D/F as*** E.O. 12866 and 13563 Review

We are taking comment on the proposed revisions to the subcategorization of ERUs, including whether we should also subcategorize for HCl and Hg. Since issuing the final CISWI rule, we have received data and information in both petitions and data submittals that indicated our inventory of ERUs used to develop the final rule standards required some adjustments to more accurately reflect the definition of solid waste in the 2011 NHSM final rule. Based on the new data, we removed five units from the final rule inventory that we determined to be non
-waste burning units, and we added three units to our inventory that we determined combust solid waste. We also received emissions data for the newly added units and re
- analyzed the performance of ERUs in the solid
biomass and solid
- coal ERU subcategories. The emi ssion limits in today’s proposal reflect the new inventory and emission data received; however, we have used the same methodology as in the final rule for establishing emission limits. We are not taking comment on this methodology. b. Waste
-burning Kilns The EPA has performed an analysis of the materials being combusted in the entire inventory of Portland cement kilns in light of the final NHSM rule (See memorandum “Revised Floors without Kilns that Would have been CISWI Kilns Had the Solid*** E.O. 12866 and 13563 Review

- calculated the MACT floor emission limi ts for the waste
-burning kilns subcategory based on the new inventory and additional data. We determined that in the case of CO emissions, it is appropriate to subcategorize by kiln type. In this case we are subcategorizing into two kiln types, long kilns (which include both dry and wet process kilns) and kilns that have preheaters (with or without precalciners. A review of the available data for CO emissions for CISWI kilns indicates that there are significant differences between CO emissions for these two types of kilns. The CO emissions from the three long kilns were all below 100 ppmv. CO emissions from the three preheater kilns were all above 300 ppmv. We note that the CO emission factors for long kilns are at least a factor of 5 less than those for pr eheater or preheater precalciner kilns. We attribute this difference to the presence of the preheater, which results in a different temperature profile than exists in the cold end section of a long kiln. As with the new ERU standards, we have used the same methodology to establish today’s proposed emission limits as we*** E.O. 12866 and 13563 Review

Establishment of Limitations on Fuel Switching Provisions The final rule included provisions to address the situation where CISWI units cease combusting solid waste, and where existing commercial and industrial facilities start combusting solid waste. Units that cease combusting solid waste remain subject to CISW I for at least 6 months after solid waste is added to the combustion chamber. After 6 months, sources must either comply with any applicable section 112 standards or, if they intend to combust solid waste in the unit in the future,*** E.O. 12866 and 13563 Review

- to - non - waste fuel switch consistent with new procedures in the final rule. Units that begin combusting sol id waste are considered affected sources under CISWI EG, and must comply as expeditiously as possible as required by the state or federal CISWI 111(d)/129 plan revision, whichever is applicable. The EPA acknowledges that sources may stop and start combust ing solid waste in their combustion units, and that regulatory procedures are necessary to guide sources through the changes in applicability that may result due to a switch in combustion materials. The provisions in the final rule account for the fact tha t facilities may start and stop combusting solid waste and ensure that any resulting changes in applicability between section 129 and section 112 rules do not occur with so much frequency that sources are unable to demonstrate continuing compliance with the applicable standards. To ensure that frequent switching does not impede our ability to determine continuous compliance and create undue permitting and testing burdens, sources remain subject to CISWI for a minimum of 6 months. The definition of CISWI uni t has been revised to clarify that a CISWI unit includes a distinct operating unit of any*** E.O. 12866 and 13563 Review

-month period. We believe this change will reduce administrative and compliance cost s to both the source and the regulatory agencies. For example, sources will not have to re - establish initial compliance with CISWI or revise their operating permit to reflect a switch out of and back into the CISWI regulations. Instead, facilities that combust solid waste would continue to be subject to the CISWI regulations for the 6 month period after waste is added to the combustion unit. For example, if a source burns waste on January 1, they would be subject to CISWI through June 30. If during that 6 month period they burned waste again, for example on March 1, the 6 month window would now be until September 30. The regulations also allow facilities to remain subject to CISWI beyond 6 months after cessation of solid waste combustion, at their own discre tion, if the source determines that continued compliance with CISWI is appropriate because the source intends to combust solid waste in the future. Source owners or operators may, alternatively, choose a date at least 6 months after ceasing solid waste combustion on which they would no longer be subject to CISWI, and would instead be subject to any applicable section 112 standards. This date is called the effective date of the waste - to - fuel switch.*** E.O. 12866 and 13563 Review

- to - non waste fuel, or non
- waste fuel
- to - waste switch, and that date becomes the date on which all of the newly applicable requirements apply. When a source begins combusting solid waste, the effective date of the non
- waste fuel
- to -waste switch must be the same as the actual date the unit begins combusting solid waste because by statute any source that combusts any solid waste is a solid waste incineration unit subject to standards under CAA section 129. See section 129(g)(1) (defining “solid waste incineration unit”). For sources that cease burning solid waste, the effective date for the waste
- to - fuel switch is a date that is at least 6 months after the last date on which solid waste is added to the combu stion unit. This allows sources that cease combusting solid waste to comply with an applicable NESHAP or opt to remain subject to CISWI at the discretion of the owner or operator. We allow the owner or operator of a CISWI unit the option of remaining subje ct to CISWI to account for sources that may want to retain the ability to burn waste intermittently without having to periodically switch between the section 112 and section 129 regulatory programs. If a source wishes to end applicability of CISWI to its unit, the source must submit an advance notification of the effective date, established as*** E.O. 12866 and 13563 Review

- to - non - waste fuel switch provisions in the final rule include requirements to conduc t performance testing that will assure compliance with all applicable standards. Specifically, performance tests must be conducted within 60 days of the date on which the unit begins combusting solid waste. In addition, the owner or operator must collect and report any PM CEMS and/or PM parametric monitoring data for those monitors that are operated at the same time as the performance test to determine whether the existing calibrations and/or correlations are still applicable. After the testing is completed , and it is demonstrated that the source is operating in compliance with the applicable standards, the owner or operator should adjust any PM CEMS calibration and any correlation for PM to correspond to the performance test results and data. The new provisions also require advance notification of the effective date of the waste

Notification must be submitted to both the EPA Regional Office and the delegated state or local agency. To ensure that frequent switching does not impede our abi lity to determine continuous compliance, sources may not switch between applicable section 129 and section 112 standards without completing the initial performance test. Therefore, sources that wish to start burning solid waste before they have demonstrate d compliance with their existing section 112 standard must complete the performance test for the 112 rule before switching to solid waste combustion. If a source switches back to a non
- waste fuel or non
- waste material for which a performance test was condu cted within the 6 months preceding the effective date of the switch, and if there are no changed conditions that would affect emissions, the source need not retest that source until 6 months from the effective date of the switch. If a source is subject to any emission limits for which compliance is determined on an annual average or other averaging period that is for a period of time greater than the period in which the source will be combusting the fuel or non
waste material, the source must comply with the emission limit averaged over the shorter time period in which the fuel or*** E.O. 12866 and 13563 Review

r olling average limit, and opts to start combusting solid waste and become subject to CISWI after combusting the fuel under the Boiler NESHAP for only 9 months, the source must demonstrate compliance with the Hg limit based on a 9 month rolling average inst ead of the annual average. The EPA believes this is necessary to assure that switching to solid waste combustion does not compromise our ability to determine compliance with standards under section 112. The rules do not allow for compliance extensions ass ociated with changes to the fuels or materials that are combusted. After the first substantive compliance date (e.g., the effective date of the state program or 5 years after publication of the final CISWI rule for incineration units), sources must be in
c ompliance with the standard that is applicable to the source based on the type of unit and the fuels or materials that are combusted. An existing source will not be considered a new source solely due to a combustion material switch. Assuming new source app licability is not triggered, existing sources that change fuels or materials are considered existing sources and, as such, they must be in compliance on the date they begin*** E.O. 12866 and 13563 Review

For all sources that commence combustion of so lid waste, the CISWI requirements become applicable on the date that the fuel switch occurs. While we believe the final rule reflects reasonable approaches consistent with the requirements of the CAA, we believe reconsideration and an additional opportuni ty for public review and comment are appropriate. Therefore, we are seeking comment on the fuel switching provisions included in the final CISWI rule, particularly on whether the provisions should include further clarification on the timeline and regulator y requirements of a fuel switch. Additionally, we are soliciting comment on an alternative time period for switching frequency (e.g., 12 months). 3. Definitions of Cyclonic Burn Barrels, Burn
- off Ovens, Soil Treatment Units, Laboratory Analysis Units, and Space Heaters from CISWI Subcategories The EPA included in the final rule definitions for units that differentiated such units from the four subcategories for which the Agency finalized standards on March 21, 2011. The definitions were not proposed and the EPA is proposing those definitions in this notice to provide the public an opportunity to comment on them. We discuss each definition below.*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 38 of 382 In the proposed CISWI rule, the EPA included cyclonic burn barrels within the definition for incinerators. Based on the information received during the comment period, the EPA determined that cyclonic burn barrels and traditional incinerators should be separate subcategories. See 40 CFR 60.2265 and 60.2875 (defining “cyclonic burn barrel” to mean a combustion device for waste materials that is attached to a 55 gallon, openhead drum. The device consists of a lid, which fits onto and encloses the drum, and a blower that forces combustion air into the drum in a cyclonic manner to enhance the mixing of waste material and air. A cyclonic burn barrel is not an incinerator, waste
-burning kiln, an ERU or a small, remote incinerator under subparts CCCC or DDDD.) In addition, information we have obtained since proposal indicates that there may be many more cyclonic burn barrels than those we have identified, and we have almost no emission data on which to set emissions standards for cyclonic burn barrels. We also received information that it is difficult, if not impossible, to test cyclonic burn barrels for the CAA section 129 po llutants using available test methods. For these reasons, we concluded in the final rules that cyclonic burn barrels were not incinerators and that we could not establish standards for such units at the time we issued the final rules. We further*** E.O. 12866 and 13563 Review

We have not received any new emission data for cyclonic burn barrels; therefore, we are not proposing to establish standards such units in this notice. We solicit comment concerning our decisions in regard to cyclonic burn barrels and the definition as set forth in the final rule. We estimated in the proposed CISWI rule tha t there were approximately 36 burn
- off ovens and we proposed standards for the subcategory based on an incomplete emission data set. We received many comments during the comment period that indicated that there may be 15,000 more units in the burn
- off oven subcategory than we had identified, and the comments also indicated that the subcategory for which we established one set of standards in fact has many different types of units that should not be regulated under one standard. Based on the comments, the la ck of data, and our determination that we did not need to regulate burn
- off ovens to comply with our CAA section 112(c)(6) obligation, we did not finalize standards for burn
- off ovens. We revised the definition of burn

-burning kilns subcategory. Commenters indicated that soil treatment units are not kilns and also that the Agency had significantly underestimated the number of such units currently in operation. Based on the comments and our determinati on that we did not need such units to comply with our CAA section 112(c)(6) obligation, we did not finalize standards for soil treatment units. We included a definition for soil treatment unit in the final rule to distinguish such units from the units for which we established standards. We have not received additional data since issuing the final standards that would allow us to adequately characterize the soil treatment unit subcategory and we are not proposing standards for such units in this reconsiderat ion notice.

The EPA concluded based on those comments that samples used in laboratory analysis units have a purpose separate from the disposal of material. Furthermore, we believe based on the information available that the material that is combusted in such units is likely not a solid waste as that term is defined in the 2011 NHSM final rule. For these reasons and because we determined we do not need such units to comply with our CAA 112(c)(6) obligation, we included in the final rule a definition of laboratory analy sis unit that distinguishes such units from the units for which we established standards. We have not received any information since issuing the final rule on the emissions from laboratory analysis units or the nature of the material combusted in such unit s that causes us to revise the conclusions reached in the final rule. We solicit comment concerning our decisions in regard to laboratory analysis units and our definition as set forth in the final rule. The EPA did not consider space heaters in the propos ed rule. The Agency received comments inquiring whether such units were subject to the proposed standards if they combusted solid waste.

As with the other units discussed in this section, the EPA does not have to regul ate space heaters to comply with the CAA 112(c)(6) obligation. We have not received any emissions information on space heaters since issuing the final CISWI standards; therefore, we are not proposing to regulate such units in the reconsideration notice. We have, however, identified typographical errors included in the definition of space heater contained in the final CISWI standards and we are proposing a definition that corrects those typographical errors: “Space heater means a usually portable appliance f or heating a relatively small area. A space heater is not an incinerator, waste -burning kiln, an energy recovery unit or a small, remote incinerator under this subpart.” We solicit comment our decisions in regard to space heaters and our revised definition set forth above. 4. Providing an affirmative defense for malfunction events The EPA recognizes that even equipment that is properly designed and maintained can sometimes fail and that such failure can sometimes cause an exceedance of the relevant emission standard.

The EPA therefore added to the final rule an affirmative defense to civil penalties for exceedances of emission limits that are caused by malfunctions. See 40 CFR 60.2265 and 60.2875 (defining “affirmative defense” to mean, in the context of an enforcement proce eding, a response or defense put forward by a defendant, regarding which the defendant has the burden of proof, and the merits of which are independently and objectively evaluated in a judicial or administrative proceeding.). We also added other regulatory provisions to specify the elements that are necessary to establish this affirmative defense; the source must prove by a preponderance of the evidence that it has met all of the elements set forth in 60.2120 and 60.2685. See 40 CFR 22.24. The criteria ensu re that the affirmative defense is available only where the event that causes an exceedance of the emission limit meets the narrow definition of malfunction in 40 CFR 60.2 (sudden, infrequent, not reasonable preventable and not caused by poor maintenance and/or careless operation). For example, to successfully assert the affirmative defense, the source must prove by a preponderance of the evidence that excess emissions “[w]ere caused by a sudden, infrequent, and*** E.O. 12866 and 13563 Review

For example, the source must prove by a preponderance of the evidence that “[r]epairs were made as expeditiously as possible when the applicable emission limitations were being exceeded....” and that “[a]ll possible steps wer e taken to minimize the impact of the excess emissions on ambient air quality, the environment and human health...” In any judicial or administrative proceeding, the Administrator may challenge the assertion of the affirmative defense and, if the responden t has not met its burden of proving all of the requirements in the affirmative defense, appropriate penalties may be assessed in accordance with section 113 of the CAA. See also 40 CFR 22.77. While we believe the final rule reflects reasonable approaches consistent with the requirements of the CAA, we believe reconsideration and additional opportunity for public review and comment should be obtained.

Revisions to the CO Monitoring Requirements In the March 21, 2011, notice of reconsideration, the EPA initiated reconsideration of the requirements to continuously monitor for CO. Petitioners have identified computational issues for correcting CO concen tration measurements to 7 percent oxygen for periods when the oxygen content of the flue gas approaches the ambient air oxygen content. The equation for the 7 percent oxygen correction is X ppm CO*(20.9

– 7)/(20.9

- %O2 of flue gas stream). As seen by this equation, as the flue gas stream oxygen content gets closer to 20.9, the value of X is multiplied by an ever increasing factor. For example, when the stack gas oxygen content is 4 percent, the factor is 0.82. If the stack gas oxygen content is 20 percent, the factor increases to 15.4. Therefore, a flue gas CO concentration reading of 100 ppm would be corrected to 82 ppm for a stack gas at 4 percent oxygen content, but would become a 1,540 ppm corrected concentration for a stack gas at 20 percent oxygen con tent. In the extreme, at a 20.8 percent stack gas concentration (i.e., approximating ambient air oxygen content), the same 100 ppm measurement would be corrected to 13,700 ppm. Petitioners have noted that oxygen contents relatively close to ambient air are often maintained during combustion unit startup and shutdown in order to safely operate the combustion*** E.O. 12866 and 13563 Review

Therefore, CO readings during these periods would be multiplied by an uncharacteristically high correction factor, and the resulting corrected CO concentrations are artificially inflated due to the 7 percent oxygen correction. Petitioners and commenters argue and presented data that show these artificially inflated data points drive the 30
- day rolling average values for the unit beyond the emission limit. Petitioners have suggested various approaches to remedy this situation, with one being to simply waive the 7 percent oxygen correction requirement during unit startup and shutdowns. In other words, the CEMS data as reported at stack gas concentratio n would be included in the rolling average calculations for periods when the combustion unit is either being started up or shutdown. During all other operating periods, the CEMS data are corrected to a 7 percent oxygen concentration prior to calculating the rolling average. We received data for one unit in one subcategory (coal ERUs) that indicates startups usually occur over a 4 hour period, and shutdowns occur over a 1hour period. Therefore, we are proposing provisions for calculating the 30
- day CO rollin g average that allow the uncorrected CEMS reading to be used during the first 4 hours of operation from a cold start and the 1 hour of operation following the last waste material being fed*** E.O. 12866 and 13563 Review

Sour ces must indicate in the CEMS data records which CEMS data are obtained during the 4 hour startup and 1 hour shutdown period. Additionally, in order to be consistent with similar requirements for non
- waste fuel
- fired boilers and process heaters, we are proposing to remove continuous CO monitoring requirements for new and existing ERU units, instead making CO monitoring with CEMS a compliance alternative and, for larger units, requiring annual CO stack tests and continuous oxygen monitoring instead. We have also removed the continuous CO monitoring requirements for new CISWI units in the other subcategories, but allow them to demonstrate compliance using CO CEMS if they so choose. The 7 percent oxygen correction waiver during startup and shutdowns discussed above would apply to any CISWI sources that elect to demonstrate compliance with the CO limits with a CO CEMS instead of performing stack tests. We are requesting comment on these proposed revisions to the final rule CO monitoring requirements. 6. Establis hing a Full

While this requirement pertains primarily to requirements contained within the major source boiler NESHAP, there are similar requirements in the final CISWI rule for exis ting units. Specifically, existing ERUs with a design heat input capacity over 100 MMBtu/hr must demonstrate continuous compliance with the CO emission limits with an annual CO stack test and monitoring the oxygen content of the flue gas using a continuous oxygen monitoring system. As discussed earlier, we have removed the CO CEMS requirements for existing units, instead allowing the option for sources to use CO CEMS to demonstrate compliance with the standards. We are also requesting comment on whether al lowing the option to use CO CEMS instead of oxygen monitoring is of potential use to affected sources and implementing agencies, and also whether the oxygen monitoring requirements coupled with an annual CO stack provides an appropriate parameter to ensure optimized combustion short of direct CO measurements. Petitioners have also commented that the final rule continuous oxygen monitoring requirements would preclude the use of existing oxygen monitoring systems that may already be installed on these units t o help manage combustor operation.*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 49 of 382 Petitioners have claimed that, by requiring the system meet Performance Specification 3 requirements, it is unlikely that existing oxygen monitors are located in a position that would enable their use for compliance demon stration. As a result, sources would need to install and operate an additional oxygen monitoring system. Petitioners contend that this additional system would be an added expense and would be located too far downstream of the combustion chamber to provide accurate data regarding combustion characteristics so would be of no use to combustor operation. We are therefore proposing revisions to the continuous oxygen monitoring provisions in today’s action that would afford the ability for existing sources to use their current oxygen analyzer and oxygen trim systems to demonstrate continuous compliance. We are requesting comment on the practicality of the proposed provisions, and whether alternative monitoring approaches are available that would ensure that the ox ygen monitoring system is sited and operated to give accurate readings while minimizing the need for potentially duplicative monitoring systems. 7. Establishing a Definition of “Homogeneous Waste”*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 50 of 382 The EPA included in the final CISWI rule a definition of h omogenous waste and a process for evaluating claims that a particular waste stream is homogenous. Homogeneous wastes are stable, consistent in formulation, have known fuel properties, have a defined origin, have predictable chemical and physical attributes , and result in consistent combustion characteristics and have a consistent emissions profile. Qualifying small power production and cogeneration facilities requesting an exemption from CISWI on the basis that they burn homogeneous waste may be asked to demonstrate, using defined test methods acceptable to the EPA, that the physical and chemical characteristics of the waste are consistent throughout such that the emission profile of any sample of waste combusted is similar or identical to any other sample. Mixtures of different types of wastes are generally not homogeneous, unless the mixtures are from materials that are each individually determined to be homogeneous, are from known origin, are mixed in constant proportion, and are conditioned or processed, such as could occur in the gasification of the wastes. MSW can never be homogeneous because it does not have a defined origin. Likewise, refuse derived fuel cannot be homogeneous because it is derived from MSW. Refuse derived fuel is also specifically excl uded from the qualifying small power*** E.O. 12866 and 13563 Review

-by
case basis. The EPA added provisions to the CISWI final rule that require source owners or operators seeking the exemption to submit a request for a homogeneous waste fuel determination to the EPA, and that they support their request with information describing the materials to be combusted and why they believe the waste is homogeneous. The final rule also indicated that the determination of what constitutes a homogeneous waste is not delegable to the state or local agencies. We are proposing the definition of homogeneous waste and the provisions for making homogenous waste determinations to provide the public an opportunity to comment on the provision. 8. Incorporating Fuel Variability into Emission Limit Calculations The proposed and final CISWI rule emission limits were calculated based primarily on emissions test data. Commenters urged the EPA to incorporate fuel variability into the emission limit calculations as was done in the boiler NESHAP. Petitioners have since claimed that the EPA did not adequately address*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 52 of 382 comments regarding this issue. In today’s proposal, we are providing further clarification on our response to this issue. In the preamble to the final CISWI rule, we explained the methodology used to establi sh the final emission limits, which relied almost exclusively on direct measurements. Commercial and Industrial Solid Waste Incineration units by definition are burning wastes, usually in combination with various non
- waste fuels, and often with a variety o f different waste streams. As a result, fuel variability data would only account for a variability found in a fraction of the materials being input into the unit. We have, in fact, considered total material feed variability in establishing limits for Hg fo r waste -burning kilns (76 FR 15727). To enable this analysis, we had to rely on data available from sources that provided materials analysis for all materials being fed into Portland cement kilns over a 30
- day span. We did not, and do not still, have such data available for other pollutants and other types of CISWI units. Therefore, we are not proposing the use of fuel variability in our emission limit methodology, except as noted above. We are requesting comments and supporting data that would allow us to consider an approach similar to the waste
-burning kiln Hg limits for other pollutants and subcategories .*** E.O. 12866 and 13563 Review

- detect Methodology Using Three Times the Detection Level Several petitioners have argued that the D/F emission limits a re based primarily on emissions data that are below detection levels and have suggested that these data not be included in emissions calculations, or at a minimum, establish a minimum emission limit value that is quantifiable by most laboratories available to analyze this data. We proposed and, in the final rule, used a methodology that sets the emission limit at a level that is at least three times the detection limit of the emission tests of the best performing units used in the MACT floor emission limit calculations. We have, however, reviewed the D/F data in more detail to ensure that all data are correctly identified as either non
- detection or detection level limited, where some of the fractions may be non
- detection, but not all of them. While our findi ngs found the most data were accurately identified, there were a few average values that were reclassified as “detection level limited.” However, these corresponding run data were correctly identified and were included in the three times the detection limi t methodology. Therefore, no D/F emission limits were impacted due to this review.*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 54 of 382 In addition, the EPA conducted a review of sampling volumes and detection levels across various emission testing ICR efforts on various combustion sources (See memorandum “ Updated data and procedure for handling below detection level data in analyzing various pollutant emissions databases for MACT and RTR emissions limits” in the CISWI docket). As a result of this analysis, we have determined recommended values for three times the RDL (3xRDL) that may be used as a minimum emission limit value that can be accurately measured by most laboratories. These recommended values were then compared with calculated emission limits and, if the calculated limit is less than the recommende d 3xRDL, the 3xRDL value is selected as the limit. This premise for this approach is the same as described in the final rule, but using a broader data set to establish the 3xRDL value. We have not changed the methodology of the emission limit calculation o r tabulation of the three times the detection limit value that was used in the final CISWI rule. Therefore, we are not accepting comment on the emission limit calculation methodology. One petitioner has suggested that D/F emission limits should not be les s than 0.3 ng/dscm. We are requesting comment and data on whether 0.3 ng/dscm or the recommended 3xRDL values for each test method are sufficient to reflect quantifiable*** E.O. 12866 and 13563 Review

sources. 10. Providing an Option for Sources to Use Emissions Averaging to Demonstrate Compliance Several petitioners contend that the EPA did not adequately address comments on the issue of allowing sources with multiple CISWI units at a facility to use emissions averaging to demonstrate compliance, similar to the provisions provided in the major source boiler NESHAP. The boiler MACT allows emissions averaging across subcategories within an affected facility. The applicability of CISWI is such that each unit is an affected facility, if it otherwise meets the applicability of the rule. We cannot allow emissions averaging across affected facilities because we establish MACT on an affected facility basis and it would be impossible to justify MACT when averaged across affected facilities. 11. Definitions a. Establishing a Definition of Foundry Sand Thermal Reclamation Unit Following publication of the final rule and the NHSM rule, we were made aware of a certain class of unit that had not previously been considered a CISWI unit, but could potentially*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 56 of 382 be considered a type of CISWI once the NHSM rule came into effect. These units are called TSR units, and are a component of a foundry’s “sand loop.” We have concluded that these units are parts reclamation units as defined in the 2000 CISWI rule. We defined parts reclamation units as “unit[s] that burn coatings off parts (e.g., tools, equipment) so that the parts can be reconditioned and reused.” In the 2011 CISWI rule, par ts reclamation units are a subcategory of burn
- off ovens. Thermal reclamation units that recover foundry sands serve the same purpose as other parts reclamation units that recover metal parts. Specifically, foundry sand units recover parts (i.e., sand) by removing coatings (e.g., binders and resins) from the foundry molds. Thus, TSR units are part reclamation units that remove coatings that are on foundry sand, which allows re
- use of the sand. As with other burn
- off ovens, TSR parts reclamation units conserve natural resources (i.e., virgin sand) and minimize the use of landfill capacity for foundry sand. As with other burn
- off ovens, we do not currently have emissions data for TSR units and regulation of such units is not required to comply with the Agency’ s CAA 112(c)(6) obligation. For these reasons, we are not proposing standards for TSR units are this time.*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 57 of 382 We are soliciting comment on the proposed definition of TSR units. b. Removing the Definition of Contained Gaseous Material The EPA did not propose to remove the definition of contained gaseous material in the proposed CISWI standards. In the final CISWI rule preamble (76 FR 15708), we removed definitions that define or clarify what constitutes a solid waste from the standards to minimize confusion i n light of the definition of solid waste in the final NHSM rule. The definition of “contained gaseous material” was one of the definitions that was removed from the 2000 CISWI standards.
Several petitioners asked for confirmation that the Agency had not changed its historical interpretation of what gases could be considered to be solid waste (i.e., a “contained gas”). These petitioners also requested that the EPA reconsider the removal of the definition of "contained gaseous material" in the CISWI rule, s ince the same definition appears in subparts EEEE and FFFF of part 60 (§60.2977 and §60.3078) and subpart III of part 62 (§62.14840). The Agency did not intend to create ambiguity by removing the definition of "contained gaseous material" from the CISWI ru le. Accordingly, the proposed CISWI reconsideration rule includes the same definition of "contained*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 58 of 382 gaseous material" that was removed from the final CISWI rule. This definition is consistent with the definition in the subparts cited above. Moreover, our p roposal to add the definition of "contained gaseous material" to the proposed CISWI reconsideration rule is consistent with the position in other sections of this preamble that address the NHSM rule where we make clear that the Agency is not changing any o f its previous positions with regard to contained gas. The EPA is soliciting comment on the need to retain the definition of contained gaseous material. c. Revising Definition of Chemical Recovery Unit Following publication of the final rule and the NHSM rule, we received additional information about a handful of combustion units that had previously not been regulated as CISWI sources, but could potentially be considered a type of CISWI unit once the 2011 NHSM final rule came into effect. However, these un its do not adequately fit into any of the four subcategories of units in the final CISWI standards. The units that have been identified are SARUs that may be burning sulfur
-bearing compounds which are classified as non
- hazardous waste at facilities that ar e non - RCRA part B permitted SARUs. Stakeholders have identified four such facilities, and have contended that response to comments and preamble language in*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 59 of 382 both the 2011 NHSM final rule and the final CISWI rule are confusing and inadequately address their particular questions on applicability of CISWI to these units. The stakeholders ask specifically which subcategory should apply to these units, noting that none of the four subcategory definitions expressly includes SARUs in their definitions. Furthermore, stakeholders note that the EPA has included a definition of chemical recovery unit in the final rule that more properly addresses SARUs as well as other types of chemical recovery unit. To address this issue and clarify applicability for chemical recover y units more generally, we are revising the definition of chemical recovery unit to clarify that chemical recovery units are not incinerators, waste
-burning kilns, ERUs or small, remote incinerators under subparts CCCC or DDDD. 12. Allowances for Using Fee d Stream Analysis or Other Supplemental Information to Demonstrate Compliance The final rule specifies emissions testing, continuous emissions monitoring, and control device parameter monitoring to ensure continuing compliance with the emission standards. Some petitioners have requested responses to comments on providing provisions that would allow use of feed stream analysis and other supplemental information instead of the monitoring requirements specified. As an example, petitioners have asked if*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 60 of 382
a sourc e could use a material analysis to show that only minimal amounts of a pollutant compound enter the combustion unit. That data, along with data on the flue gas flow rate information could be used by sources to calculate a maximum possible pollutant concent ration. The petitioners further argue that the source could then demonstrate that the maximum potential concentration is less than the applicable emission limit, and the source would not have to perform an emissions test for that pollutant. We have not proposed any such provisions in today’s rule, and believe that direct measurement of emissions is the most comprehensive and accurate method to ascertain compliance with the final standards. Furthermore, CAA section 129(c) states that the EPA “shall... promulga te regulations requiring the owner or operator of each solid waste incineration unit

– (1) To monitor emissions from the unit at the point at which such emissions are emitted into the ambient air... and at such other points as necessary to protect public hea lth and the environment.” The EPA is thus constrained by the statute in our ability to implement the commenter’s proposed monitoring approach. 13. Providing Percent Reduction Alternative Standards The final rule contains numeric emission limits for all ni ne pollutants listed in CAA section 129(a)(4)(requiring*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 61 of 382 numerical emissions limits for the 9 identified pollutants). The proposed and final rules describe at length the methodology used to establish these emission limits. However, petitioners and commenter s suggested that the EPA should also establish alternative percent reduction standards to the numeric emission limits. Petitioners allege that we did not adequately address this comment in the preamble to our final rule or supporting documents. Therefore, we are providing our response to this issue in today’s proposal. The CISWI database does not include percent removal data except in very limited instances. These data were seldom provided voluntarily, and were not required by the EPA during the emission te st ICR. This is due to the increased cost of performing pre
- and post
- emission control device emissions tests to determine the removal efficiency of the control device. Source operators will typically not choose to perform extra testing at additional cost voluntarily, and the EPA went to great lengths to minimize burden on sources during the testing ICR. As a result, we do not have percent reduction data for the best performing CISWI sources, and cannot develop a percent reduction alternative standard that reflects the best sources’ performance.*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 62 of 382 Additionally, there are arguments that percent reduction standards are not legally permissible (See 74 FR 21149). As discussed in the Portland cement NESHAP proposal preamble, the Brick MACT opinion states “that bes t performers are those emitting the least HAP.” It further discusses how a percent reduction standard downplays the role of pollutant inputs on emissions, thereby allowing more pollutants to be emitted provided a given level of removal efficiency. Finally, we do not specify the control devices necessary to meet the numeric limits as in some other rules. Sources may evaluate their source emissions and determine the appropriate control strategy or devices needed to comply with the emission limits. Per cent reduction standards are more appropriately applied when there is a specified control device that potential emission streams must be routed through, such as a flare. In these cases, a percent reduction alternative provides a design and performance metr ic for the required type of control device. This is not the case with CISWI since the rule does not specify a control device for all sources. Due to the reasons discussed above, we have not proposed any percent reduction alternative standards. 14. Providi ng Parametric Monitoring Provisions for Additional Control Device Types*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 63 of 382 The final rules added monitoring parameters for sources that use wet scrubbers, ESPs, activated carbon sorbent injection, or SCR. However, one petitioner has claimed that we did not adequately address comments on this issue in the final rule preamble or supporting documents. Therefore, we are responding that we have included such provisions that commenters requested. The control devices with monitoring provisions expressly identified in the rules should encompass most types of control devices that we would anticipate the various types of CISWI units to use to meet the emission limits. In the case that there is another type of control that is not addressed, we have provided provisions for sources to petition for specific operating limits for the control device to be established during a performance test. These provisions also allow specific operating limits to be established for CISWI units without any air pollution control devices, such a s material balance operating limits to demonstrate continuous compliance. However, we recognize that dry sorbent injection for acid gas control may be one additional type of control that affected sources may use, and are requesting comment on whether we sh ould specify monitoring provisions for this type of control and recommendations on which parameters should be specified. Lastly, we also request comment on whether there are any additional*** E.O. 12866 and 13563 Review

Revisions to the Continuous Monitoring Provisions for Large ERUs In today’s rule, we are proposing some revisions to the monitoring requirements for ERUs with a design heat input capacity greater than 250 MMBtu/hr. In the final rul es, these units were required to monitor continuously for PM using a PM CEMS ; however , recent EPA experience with the utility boiler source category has led the EPA to allow PM CEMS as an alternative, rather than a requirement. The PM CEMS technology may n ot be sufficient to certify accurate monitor performance in the PM concentration range of the CISWI ERU limits. Therefore, we are requiring continuous parameter monitoring systems for these units similar to those being required for major industrial boilers and utility boilers. Likewise, to be consistent with these other rules, we have revised all operating parameter averaging for ERU units to be on a 30
- day rolling average. Due to the relatively long operational campaigns of ERUs, the longer averaging time will allow operators sufficient flexibility for operational and control device adjustments should they be needed for short term fuel or waste characteristics variability. The EPA has determined the 30
- day rolling average reporting basis is*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 65 of 382 appropriate for this rule. The operating limits established through performance testing in this rule represent short term process and control operating conditions representative of compliance. Concerns of variability outside the operators control such as fuel content, sea sonal factors, load cycling, and infrequent hours of needed operation prompted us to look at longer averaging periods on which to base operating compliance determination. We are aware from studies of emissions over long averaging periods (See memorandums “ Changing Averaging Time as an Incentive” and “Assessment of Using Single Point Stack Test Data to Derive 30
- Day Rolling Average Emissions Limits” in the CISWI docket) that long term (e.g., 30
- day) average emissions for a operating in compliance will have a variability of about half of that represented by the results of short term testing. Given that short term tests are representative of distinct points along a continuum of that inherent operational variability, we believe it appropriate to provide a means for the source operator to account for that variability by applying a long term average for establishing compliance. We expect more problematic control system variability (e.g., ESP transformer failure or scrubber Venturi fan failure) to result in deviatio ns from a 30
- day average relative to compliance almost as much as for a shorter term average.*** E.O. 12866 and 13563 Review

The EPA plans to reset the compliance dates of the rule when the final reconsideration is published. The EPA is proposing to set the compliance date for existing sources in the incinerator, ERU, and waste
-burning kiln subcategories 5 years after the date of publication of the final reconsideration rule or 3 years after the state plan is approved, whichever happens earlier. This date is being proposed in order to provide facilities sufficient time to install controls or to make other compliance
- related decisions. For new sources in the incinerator, ERU, and waste -burning kiln subcategories, the EPA is proposing to change the compliance date to 6 months after the date of publication of the final reconsideration rule. Since there were no major changes to the emission standards from final rule for the small remo te incinerator subcategory, the EPA is soliciting comment on the need to extend the compliance date for this subcategory. Particularly, the EPA is requesting additional data that supports the need to revise the emission standards for the small remote incin erator subcategory. The EPA determined that it is appropriate to extend the compliance dates for the incinerator, ERU, and waste
-burning*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 67 of 382 kiln subcategories for several reasons. First, proposed changes to the emission limits for these subcategories will have a significant impact on the compliance strategies that are selected by the affected sources. For instance, the proposed changes in emission limits for existing ERU, and waste
-burning kiln subcategories may require different control strategies selections than the emission limits finalized in March 2011. Second, when the EPA announced the reconsideration and issued the stay of the effective date, a signal was sent to industry and to the states responsible for implementing the EG that requirements may change significantly. The resulting uncertainty has limited the ability of affected sources to begin making appropriate selections of control technologies and other compliance decisions. Even if significant changes were not being proposed, an extended complianc e date would likely be necessary to provide enough time for facilities to achieve compliance. Additionally, not extending the compliance date may be problematic for states and implementing agencies since the increments of progress for rule compliance are keyed off of the approval date of the revised state plan. Without a final rule in place, states and implementing agencies will be unable to adequately update and implement a state plan. For all of the reasons discussed above, the EPA has determined that it is*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 68 of 382 necessary to extend the compliance date for existing sources in the ERU and waste
-burning kiln subcategories based on the date that the reconsideration of the final rule is completed. Finally, the EPA has received comments that the availability of contr ol equipment and vendors to install control equipment for CISWI units is in question due to the large number of units requiring controls in conjunction with the parallel rulemaking for industrial boilers and electric generating units that will require cont rols from many of the same vendors. While the EPA believes that the maximum time allotted under section 129 provides enough time for CISWI units to achieve compliance, the EPA recognizes that maintaining the compliance dates from the final rule would essen tially provide less than 2 years for states to implement a revised state plan and for increments of progress to be scheduled. Because the stringency of the final standards will not be determined until the reconsideration is final, sources will not be able to begin planning a compliance strategy and states will be uncertain on an appropriate schedule for increments of progress, which includes submittal of a final control plan. The EPA is requesting comment on the proposed changes to the compliance dates. D. Technical Corrections and Clarifications*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 69 of 382 In today’s rule, we are also proposing some changes to the final rule to correct minor typographical errors and clarify portions. This section of the preamble summarizes these corrections and clarifications. 1. Providing a Definition of Municipal Solid Waste We are including the definition of “municipal solid waste” in the CISWI rule definitions. This definition is the same definition used in the CAA section 129 standards for MWC units. We believe that including thi s definition will further clarify applicability for MWC owners who question whether CISWI or MWC rules are applicable to their solid waste combustion unit. 2. Energy Recovery Units Designed to Burn Non
- coal Solid Materials We are amending the definition o f “Energy recovery unit designed to burn biomass (Biomass)” to clarify that this definition applies to all ERUs designed to burn non
- coal solid materials. While we believe biomass to be the majority of such materials, we wanted to more broadly define this source category to clarify applicability for ERUs that are burning less than 10 percent coal on a heat input basis. We are also amending recordkeeping requirements for ERU units to require records of fuel inputs to ensure that the units are meeting the app licability for coal or non
- coal ERUs.*** E.O. 12866 and 13563 Review

 Final rule §60.2165, a new paragraph break is needed for (n) (4);
 Final rule §60.2265, a new paragraph break is needed for the definition of “Solid waste incineration unit;”
 Amendatory instruction #50, paragraph (b) was not added but was amended; and
 Footnote "a" for Table 9 to Subpart DDDD does not have the sentence al lowing facilities to meet either the Total or TEQ for the D/F standard. It is included in all other tables (for new and existing sources). E. Environmental, Energy and Economic Impacts 1. What are the Primary Air Impacts? We have estimated the potential emissions reductions from existing sources that may be achieved through implementation of the emission limits. However, we realize that some CISWI owners and operators are likely to determine that alternatives to waste incineration are viable, such as furthe r waste segregation or sending the waste to a landfill or MWC, if available. In fact, sources operating incinerators, where energy recovery is not a goal, may find it cost
- effective to discontinue use of their CISWI unit altogether. Therefore, we have estimated emissions reductions attributable to existing sources complying with the limits, as well as those reductions that would occur if the facilities with incinerators and small, remote incinerators*** E.O. 12866 and 13563 Review

For units combusting wastes for energy production, such as ERUs and waste -burning kilns, the decision to combust or not to combust waste will depend on several factors. One factor is the cost to replace the energy prov ided by the waste material with a traditional fuel, such as natural gas. Another factor would be whether the owner or operator is purchasing the waste or obtaining it at no cost from other generators, or if they are generating the waste on
- site and will have to dispose of the materials in another fashion, such as landfills. Lastly, these units would have to compare the control requirements needed to meet the CISWI emission limits with those needed if they stop burning solid waste and are then subject to a NESHAP instead. As mentioned before, we have attempted to align the monitoring requirements for similar non
-waste -burning sources as closely as possible in an effort to make them consistent and to help sources make the cross
- walk between waste and non
- waste regulatory requirements as simple as possible. The emissions reductions that would be achieved under this proposed rule using the definition of solid waste under RCRA and the proposed CISWI emission limits are presented in Table 4 of this preamble.*** E.O. 12866 and 13563 Review

Our experience with regulations for MWC, HMIWI and, in fact, CISWI, has shown that negative growth in the source category historically occurs upon implementation of CAA section 129 standards. Since CISWI rules were promulgated in 2000 and have been in effect for existing sources since 2005, many existing units have closed. At promulgation in 2000, the EPA estimated 122 units in the CISWI population. In comparison, the incinerator subcategory in this*** E.O. 12866 and 13563 Review

The EPA is not aware of any construction of new units since 2000, so we do not believe there are any units that are currently subject to the 2000 CISWI N SPS. The revised CISWI rule is more stringent, so we expect this trend to continue. However, the EPA does recognize that some facilities may opt to replace aging incinerator units with new units where it is cost
- effective or alternative disposal options ar e not feasible, as may be the case with some incinerators, or in very remote locations. We estimate that there could be one new incineration unit within the next 5 years following this proposal, and possibly five new small remote incinerators within that t ime. In these cases, we have developed model CISWI unit emissions reduction estimates for these subcategories using the current existing unit baseline, based on average emission concentration values and sizes from our current inventory and the new source p roposed emission limits. Table 5 of this preamble presents the model plant emissions reductions that would be expected for new sources. **Table 5. Emissions Reductions on a Model Plant Basis**

derived fuel from which the metal has been removed is not considered solid waste under the definition of solid waste. Consequently, new cement kiln owners will assess their regula tory requirements under CISWI for burning whole tires or tire

Our research suggests that metal removal is routinely practiced and that several state waste tire management programs are already in place, and would most likely be a viable option for new kiln owners so that they would not be subject to the CISWI regulations. Indeed, we expect that all*** E.O. 12866 and 13563 Review

-burning solely due to whole tires will, by the compliance date for the CISWI standards, find a way to obtain their tires through an approved tire mana gement plan. Likewise, new sources could engineer their process to minimize waste generation in the first place, or to separate wastes so that the materials sent to a combustion unit would not meet the definition of solid waste to begin with. For waste tha t is generated, our cost analyses have found that alternative waste disposal is generally available and less expensive. 2. What are the Water and Solid Waste Impacts? In our analysis, we have selected the lowest cost alternative (i.e., compliance or altern ative disposal) for each facility. We anticipate affected sources will need to apply additional controls to meet the emission limits. These controls may use water, such as wet scrubbers, which would need to be treated. We estimate an annual requirement of 90 billion gallons per year of additional water would be required as a result of operating additional controls or increased sorbent use. Likewise, the addition of PM controls or improvements to controls already in place will increase the amount of particul ate collected that will require disposal. Furthermore, ACI may be used by some sources, which will result in additional*** E.O. 12866 and 13563 Review

The annual amounts of solid waste that would require disposal are anticipated to be approximately 22,549 tpy from PM capture and 9,820 tpy from ACI. Perhaps the largest impact on solid waste would come from owners and operators who decide to discontinue the use of their CISWI unit and instead send waste to the landfill or MWC for disposal. Based on tipping fe es and availability, we would expect most, if not all, of this diverted waste to be sent to a local landfill. As we discuss above, it may be that a good portion of the incinerators would determine that alternative disposal is a better choice than complianc e with the standards. We estimate that approximately 110,417 tpy of waste would be diverted to a landfill. For new CISWI units, we estimate an annual requirement of 9,102 million gallons per year of additional water would be required as a result of operat ing additional controls. The annual amounts of solid waste that would require disposal are anticipated to be approximately 7,275 tpy from PM capture and 8,173 tpy from ACI. 3. What are the Energy Impacts? The energy impacts associated with meeting the emis sion limits would consist primarily of additional electricity needs to run added or improved air pollution control devices. For*** E.O. 12866 and 13563 Review

In our analysis, we have selected the lowest cost alternative (i.e., compliance or alternative disposal) for each facility. By our estimate, we anticipate that an additional 242,283 MW
- hours pe r year would be required for the additional and improved control devices. As discussed earlier, there could be instances where owners and operators of ERUs and waste -burning kilns decide to cease burning waste materials. In these cases, the energy provided by the burning of waste would need to be replaced with a traditional fuel, such as natural gas. Assuming an estimate that 50 percent of the energy input to ERUs and kilns are from waste materials, an estimate of the energy that would be replaced with a tr aditional fuel if all existing units stopped burning waste materials, is approximately 56 TBtu/yr. For new CISWI units, we anticipate that 511 MW
- hours per year would be required for additional and improved control devices. Since we do not anticipate any new energy recovery or waste -burning kiln units to be constructed, there would be no additional estimate for energy that would be replaced with a traditional fuel.*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 78 of 382 4. What are the Secondary Air Impacts? For CISWI units adding controls to meet the emission limits, we anticipate minor secondary air impacts. The combustion of fuel needed to generate additional electricity and to operate RTO controls would yield slight increases in emissions, including NOx , CO, PM and SO 2 and an increase in CO 2 emissions. Since NOx and SO 2 are covered by capped emissions trading programs, and methodological limitations prevent us from quantifying the change in CO and PM, we do not estimate an increase in secondary air impacts for this rule from additional electricity demand. We believe it likely that the incinerators may elect to discontinue the use of their CISWI unit and send the waste to the landfill or other disposal means. As we discussed in the solid waste impacts above, this could result in approximately 110,417 tpy of waste going to landfills. By using the EPA’s Landfill Gas Estimation Model, we estimate that, over the 20
- year expected life of a CISWI unit, the resulting methane generated by a landfill receiving the waste would be about 96,300 tons. If this landfill gas were combusted in a flare, assuming typical flare emission factors and landfill gas chlorine, Hg, and sulfur concentrations, the following emissions*** E.O. 12866 and 13563 Review

Similar to existing units, we anticipate minor secondary air impacts for new CISWI units adding controls as discussed above. 5. What are the Cost and Economic Impacts? We have estimated compliance costs for all existing units to add the necessar y controls and monitoring equipment, and to implement the inspections, recordkeeping and reporting requirements to comply with the proposed CISWI standards. We have also analyzed the costs of alternative disposal for the subcategories that may have alterna tive options to burning waste, specifically for the incinerators and the small, remote incinerators that may have an alternative to incineration. In our analysis, we have selected the lowest cost alternative (i.e., compliance or alternative disposal) for e ach facility. Based on this analysis, we anticipate an overall total capital investment of $859 million with an associated total annual cost of $270 million ($2008). Under the rule, the EPA’s economic model suggests the average national market
- level variab les (prices, production
levels, consumption, international trade) will not change significantly (e.g., are less than 0.02 percent).*** E.O. 12866 and 13563 Review

The EPA’s analysis found the tests were below 3 percent for five of the nine small entities included in the screening analysis. In addition to estimating this rule’s social costs and benefits, the EPA has estimated the employment impacts of the final rule. We expect that the rule’s direct impact on employment will be small. We have not quantified the rule’s indirect or induced impacts. For further explanation and discussion of our analysis, see Chapter 4 of the RIA. For new CISWI units, we have estimated compliance costs for units coming online in the next 5 years. This analysis is based on the assumption that one new incinerator will come online over 5 years and one new small, remote incinerator will come online each year over the next 5 years. Additionally, it was assumed that each model unit will add the necessary controls, monitoring equipment, inspections, recordkeeping, and reporting requirements to comply with NSPS limits. Based on our analysis, we anticipate an overall total capital investment of $8.4 million over 5 years with an associated total annual cost (for 2015) of $2.6 million. 6. What are the Benefits?*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 81 of 382 We estimate the monetized benefits of this regulatory action to be $330 million to $800 million (2008$), 3 percent di scount rate) in the implementation year (2015). The monetized benefits of the regulatory action at a 7 percent discount rate are $300 million to $720 million (2008$). These estimates reflect energy disbenefits valued at $3.8 million. Using alternate relati onships between PM2.5 and premature mortality supplied by experts, higher and lower benefits estimates are plausible, but most of the expert
-based estimates fall between these two estimates. 1 A summary of the monetized benefits estimates at discount rates of 3 percent and 7 percent is in Table 6 of this preamble. **Table 6. Summary of the Monetized Benefits Estimates For the CISWI NSPS and EG in 2015 (Millions of 2008$)**  **a,b**

Benefits from reducing HAP are not included. These estimates do not include the energy disbenefits valued at $3.8 million, but the rounded totals do not change. CO2
- related di sbenefits were calculated using the social cost of carbon, which is discussed further in the RIA. b The estimates in this table reflect the estimates in the RIA. Due to last minute changes to the March 2011 final CISWI rule, we were unable to incorporate the final engineering costs and emission reductions into the RIA, which would decrease the costs by approximately 22 percent and increase the monetized benefits by approximately 4 percent from those shown here. These benefits estimates represent the total monetized human health benefits for populations exposed to less PM2.5 in 2015 from controls installed to reduce air pollutants in order to meet these standards. These estimates are calculated as the sum of the monetized value of avoided premature mortalit y and morbidity associated with reducing a ton of PM2.5 and PM2.5 precursor emissions. To estimate human health benefits derived from reducing PM2.5 and PM2.5 precursor emissions, we used the general approach and methodology laid out in Fann, Fulcher, and Hubbell (2009). 2 To generate the benefit
-per - ton estimates, we used a model to convert emissions of direct PM2.5 and PM2.5 precursors into changes in ambient PM2.5 levels and another model to estimate

-per - ton estimates. These models assume that all fine particles, regardless of their chemical composition, are equally potent in causing premature mortality because there is no clear scientific evidence that would support the development of differential effects estimates by particle type. Directly emitted PM2.5 , SO 2 and NOx are the primar y precursors affected by this rule. Even though we assume that all fine particles have equivalent health effects, the benefit
-per - ton estimates vary between precursors because each ton of precursor reduced has a different propensity to form PM2.5 . For example, SO 2 has a lower benefit
-per - ton estimate than direct PM2.5 because it does not directly transform into
PM2.5 , and because sulfate particles formed from SO 2 emissions can transport many miles, including over areas with low populations. Direct PM2.5 emi ssions convert directly into ambient PM2.5 , thus, to the extent that emissions occur in population areas, exposures to direct PM2.5 will tend to be higher, and monetized health benefits will be higher than for SO 2 emissions.*** E.O. 12866 and 13563 Review

Experts have advised the EPA to consider a variety of assumptions, including estimates based on both empirical (epidemiological) studies and judgments elicited from scientific experts, to characterize the uncertainty in the relationship between PM2.5 concentrations and premature mortality. For this rule, we cite two key empirical studies, the American Cancer Society cohort study 3 an d the extended Six Cities cohort study. 4 In the RIA for this rule, which is available in the docket, we also include benefits estimates derived from expert judgments and other assumptions. The EPA strives to use the best available science to support our be nefits analyses. We recognize that interpretation of the science regarding air pollution and health is dynamic and evolving. After reviewing the scientific literature and recent scientific advice, we have determined that the no
- threshold model is the most appropriate model for assessing the mortality benefits associated with reducing PM2.5 exposure. Consistent with this recent advice, we are replacing the previous threshold

While a LML assessment provides some insight into the level of uncertainty in the estimated PM mortality benefits, the EPA does not view the LML as a threshold and continues to quantify PM
- related mortality impacts using a full range of modeled air quality concentrations. Most of the estimated PM
- related benefits in this rule would accrue to populations exposed to higher levels of PM2.5. Using the Pope, et al., (2002) study, 85 percent of the population is exposed at or above the LML of 7.5 μg/m3 . Using the Laden, et al., (2006) study, 40 percent of the population is exposed above the LML of 10 μg/m3 . It is important to emphasize that we have high confidence in PM2.5 - related effects down to the lowest LML of the major cohort studies. This fact is important, because as we estimate PM
- related mortality among populations exposed to levels of PM2.5 that are successively lower, our confidence in the results diminishes. However, our analysis shows that the great majority of the impacts occur at higher exposures . This analysis does not include the type of detailed uncertainty assessment found in the 2006 PM2.5 NAAQS RIA because we lack the necessary air quality input and monitoring data to run the benefits model.

The 2006 PM2.5 NAAQS benefits analysis 5 provides an indication of the sensitivity of our results to various assumptions.

The benefits from reducing HAP have not been monetized in this analysis, including reducing 25,000 tons of CO, 470 tons of HCl, 4.1 tons of Pb, 0.95 tons of Cd, 260 poun ds of Hg and 92 grams of total D/F each year. Although we do not have sufficient information or modeling available to provide monetized estimates for this rulemaking, we include a qualitative assessment of the health effects of these air pollutants in the RIA for this rule, which is available in the docket.

Section 129(g)(6) provides that the term “solid waste” is to be established by the EPA under RCRA (42 U.S.C. 7429). Section 2002(a)(1) of RCRA authorizes the Agency to promulgate regulations as are necessary to carry out its functions under the Act.

These fuels are not secondary materials or solid wastes unless discarded. Clean biomass is biomass that does not contain contaminants at concentrations not normally associated with virgin biomass materials.” In accordance with the above traditional fuels definition, clean construction and demolition wood could be combusted as a traditional fuel if it does not contain contaminants at concentrations not normally associate d with virgin wood. However, the final NHSM rule also addressed construction and demolition wood that may contain contaminated material (76 FR 15485). Additionally, construction and demolition wood that has been processed (e.g., sort ed) to remove contaminants ( such as lead
-painted wood, treated wood containing contaminants such as arsenic and chromium, metals and other no n - wood materials), and is size

as a non - waste fuel. S uch construction and demolition wood may contain de minimis amounts of contaminants and other materials provided it meets the legitimacy criter ia for co ntaminant levels (76 FR 154586) . See section II.D.1 for more information regarding the revised definition of “clean cellulosic biomass.” b. Contaminants The 2011 NHSM final rule defined “contaminants” as meaning “any constituent in non
- hazardous s econdary materials that will result in emissions of the air pollutants identified in Clean Air Act section 112(b) or the nine pollutants listed under Clean Air Act section 129(a)(4) when such non
- hazardous secondary materials are burned as a fuel or used a s an ingredient, including those constituents that could generate products of incomplete combustion” (codified in 40 CFR 241.2). The EPA is proposing to revise the definition of “contaminants” to clarify what will be considered contaminants for the purpos es of the legitimacy criteria. Specifically, several pollutants listed in CAA sections 112(b) and 129(a)(4) form during combustion, so elemental precursors to those pollutants that are found in the NHSM prior to combustion are being added to the revised co ntaminant definition in place of the pollutants themselves. In addition, those pollutants from*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 95 of 382 CAA section 112(b) and 129(a)(4) lists that we do not expect to find in any NHSM are also specifically excluded from the definition of contaminants (see discussi on in section II. D.1.b). We do not expect this change to affect any of the decisions previously made on whether NHSMs are solid wastes when burned as fuels. We are also proposing to revise this definition to clarify that, for the purpose of meeting the c ontaminant legitimacy criterion, contaminant levels found in the NHSM prior to being fed into combustion units, should be evaluated rather than emissions from those units. Specifically, there appears to be confusion within the regulated community that in determining whether or not a NHSM meets the “contaminant legitimacy criterion,” emissions from the combustion unit are to be considered in making such an evaluation. Both in today’s proposal and in the 2011 NHSM final rule preamble and regulatory text, it was clear that the NHSM itself was to be evaluated and not the emissions from the combustion unit. This approach is more appropriate, since the question is whether or not a NHSM is being burned for discard, and elevated contaminant levels in the NHSM could be indicative of burning for discard. Thus, the EPA is clearing up any inadvertent ambiguity in the regulation itself. The rationale for this approach can be found in the*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 96 of 382 rulemaking record for the final rule. 8 EPA is not proposing any revisions to that app roach, but is simply clarifying the regulatory text to better reflect the Agency’s intention. Thus, the Agency is proposing to revise the definition of “contaminants” as follows: “Contaminants means all pollutants listed in Clean Air Act sections 112(b) an d 129(a)(4), with modifications outlined in this definition to reflect constituents found in non
- hazardous secondary materials prior to combustion. The definition includes the following elemental contaminants that commonly form Clean Air Act section 112(b) and 129(a)(4) pollutants: antimony, arsenic, beryllium, cadmium, chlorine, chromium, cobalt, fluorine, lead, manganese, mercury, nickel, nitrogen, selenium, and sulfur. The definition does not include the following Clean Air Act section 112(b) and 129(a)( 4) pollutants that are either unlikely to be found in non
- hazardous secondary materials prior to combustion or are adequately measured by other parts of this definition: hydrogen chloride (HCl), chlorine gas (Cl2), hydrogen fluoride (HF), nitrogen oxides ( NOx ), sulfur dioxide (SO 2 ), fine mineral fibers, particulate matter, coke oven emissions, diazomethane, white phosphorus, titanium tetrachloride, m

Established Tire Collection Programs The EPA is proposing to revise the definition of “established tire collection progr ams” to clarify that off
specification tires (including factory scrap tires) are not discarded when combusted, in the same way as tires that are removed from vehicles. The 2011 NHSM final rule defined “established tire collection program” as meaning “a comprehensive collection system that ensures scrap tires are not discarded and are handled as valuable commodities in accordance with section 241.3(b)(2)(i) from the point of removal from the vehicle through arrival at the combustion facility” (codified in 4 0 CFR 241.2). However, that definition did not account for “factory scrap” or “off
- specification” tires that are contractually arranged to be collected, managed, and transported between a tire manufacturer (including retailers or other parties involved in the distribution and sale of new tires) and a combustor, which is analogous to how scrap tires removed from vehicles are managed.*** E.O. 12866 and 13563 Review

Contaminant Legitimacy Criterion for NHSM Used as Fuels The 2011 NHSM final rule codified three self
- implementing legitimacy criteria that NHSM must meet in order to be considered a non - waste fuel when burned in a combustion unit (40 CFR 241.3(d)(1)(i)
- (iii)). One of these criteria focused on comparing levels of contaminants contained in the NHSM to levels of those constituents found in traditional fuels. Specifically, the contaminan t legitimacy criterion for fuels was finalized as follows: “The non
- hazardous secondary material must contain contaminants at levels comparable in concentration to or lower than those in traditional fuels which the combustion unit is designed to burn. Such comparison is to be based on a direct comparison of the contaminant levels in the non
- hazardous secondary material to the traditional fuel itself.” 40 CFR 241.3(d)(1)(iii). The existing language provides flexibility for*** E.O. 12866 and 13563 Review

- group of contaminants basis in determining what constituents to compare. The phrase “traditional fuels which the combustion unit is designed to burn” also provides the flexibility to choose among multiple fuel options. I ndustry groups have expressed concern that the regulatory language does not clearly reflect the EPA’s intent 9 . The EPA agrees that the regulatory language can be revised to better reflect the EPA’s intent in implementing the con taminant legitimacy criterion. Therefore, the Agency is proposing to revise this criterion to read, “The non
- hazardous secondary material must contain contaminants or groups of contaminants at levels comparable in concentration to or lower than those in t raditional fuel(s) which the combustion unit is designed to burn. In determining which traditional fuel(s) a unit is designed to burn, persons can choose a traditional fuel that can be or is burned in the particular type of boiler, whether or not the combu stion unit is permitted to burn that traditional fuel. In comparing contaminants between traditional fuel(s) and a non
hazardous secondary material, persons can use ranges of

Such comparisons are to be based on a direct comparison of the contaminant levels in both the non
- hazardous secondary material and traditional fuel(s) prior to combustion.” We are taki ng comment on how this revised contaminant legitimacy criterion would apply to specific fuels. For more information regarding the proposed revisions to the contaminant legitimacy criterion for NHSM used as fuels, see section II.D.2 of today’s proposed rule . 1. Categorical Non
-Waste Determinations for Specific NHSM Used as Fuels The EPA is proposing to identify several NHSMs as not being solid waste when burned as a fuel in a combustion unit where the Agency has sufficient information to determine that discard is not occurring when these materials are being used as fuels. Specific ally, the Agency recognizes that certain NHSMs may not meet the legitimacy criteria, especially the “contaminant legitimacy criterion,” in all instances, but the material would still generally be considered a non
- waste fuel. While we do not agree it is app ropriate for the regulated community to make these judgments as part of the self
- implementing aspects of the NHSM final rule, it is appropriate that the Agency do so, by*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 101 of 382 balancing the legitimacy criteria and such other relevant factors that the Administrat or may identify, in determining that a NHSM is not a solid waste when used as a fuel in a combustion unit. Thus, in today’s proposed rule, we are identifying the following specific materials as non
- waste fuels: (1) scrap tires that have not been discarded and are managed under the oversight of established tire collection programs, including tires removed from vehicles and off
- specification tires, and (2) resinated wood. Thus, persons who burn these NHSMs as a fuel would not need to evaluate them using the s elf
- implementing legitimacy criteria when burned. In addition, the Agency recognizes that there may be other NHSMs that should also be considered non
- waste fuels, based on a balancing of the legitimacy criteria with other relevant factors. Therefore, we a re proposing to create a petition process that would provide the regulated community an opportunity to submit a rulemaking petition to the EPA for a determination that a particular NHSM that should not be considered solid waste when burned as a fuel in a c ombustion unit. This process could be used when a facility does not believe that the self
- implementing legitimacy criteria yields a clear result or does not accurately reflect whether the material is being discarded. A brief discussion of the specific NHSMs*** E.O. 12866 and 13563 Review

See section II.D.3 and 4 of today’s proposed rule for a detailed discussion of these topics. a. Scrap tires In the 2011 NHSM final rule, the EPA determined that scrap tires removed from vehicles and managed pursuant to established tire collection programs would not be co nsidered a solid waste. This determination was codified in §241.3(b)(2)(i). This determination was made after the EPA analyzed scrap tires removed from vehicles and managed pursuant to established tire collection programs and concluded that (1) these mater ials would meet the legitimacy criteria for fuels, and (2) these materials were not discarded when transferred off
- site from the generating facility 10
. Since promulgation of the 2011 NHSM final rule, the EPA has received information that tire manufacturer s, including downstream distribution channels, may produce tires that are not suitable for use on vehicles, but like the tires removed from vehicles, are usable as legitimate fuels. They are, for all

- specification tires (including factory scrap tires) that are contractually arranged to be col lected, managed, and transported between a tire manufacturer, which would include retailers and other parties involved in the distribution and sale of new tires and a combustor. We note that tires coming from vehicles that are part of an established tire
c ollection program would be a non
-waste fuel under the 2011 NHSM final rule. The EPA is not reopening this determination in today's proposed rule. For clarity, the Agency is proposing to add scrap tires that are not discarded and are managed under the overs ight of established tire collection programs, including tires removed from vehicles and off
- specification tires, to the categorical list of non
- waste fuels (see 40 CFR 241.4(a)). For more on this determination and the off
- specification tires from tire
manu facturers or downstream distribution channels, see section II.D.3 of today’s proposed rule. b. Resinated Wood The 2011 NHSM final rule determined that resinated wood is not a solid waste when used as a fuel regardless of whether it*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 104 of 382 remained within the con trol of the generator (see 40 CFR 241.3(b)(2)(ii)). This determination was made after the EPA analyzed resinated wood and concluded that (1) resinated wood generally would meet the legitimacy criteria for fuels, and (2) resinated wood was not discarded whe n transferred off
- site from the generating facility 11 . Today’s action proposes to revise part 241 to state affirmatively that resinated wood, when used as a fuel, is not being burned for discard and is not a solid waste. We are proposing to codify this dete rmination based on our belief that the use of resinated wood as fuel represents an integral component to the wood manufacturing process and, as such, resinated wood is not being discarded, and therefore not solid waste, when burned as fuel. For more on thi s proposed revision, see section II.D.3 of today’s proposed rule. c. Rulemaking Petition Process for Other Non
-Waste Determinations Under today’s rule, the Agency is proposing to create a rulemaking petition process that would provide persons an opportuni ty to submit a rulemaking petition to the Administrator, seeking a categorical determination for additional NHSMs to be listed in section 241.4(a) as non
- waste fuels. The process for submitting a rulemaking petition to the

Parties can prese nt information including data demonstrating that manure is not discarded either through the existing non
- waste petition process or the proposed categorical determination process. 4. Additional Request for Comment As discussed elsewhere in this preamble, the Agency requests additional information regarding pulp and paper sludge in order for the Agency to determine whether a categorical determination that pulp and paper sludge is a non
- waste, when used as fuel, is appropriate. Information that would be part icularly helpful includes: (1) documentation of how the use of pulp and paper sludges that are used as a fuel are integrated into the industrial production process and the steps taken industry
- wide to ensure that this NHSM is consistently used as a legitimate fuel and is not discarded, including when transferred to a different person for use as a fuel; (2) documentation on the amount of pulp and paper sludges burned as a fuel (whether within the control of the generator or outside the control of the generat or), and what determines which pulp and paper sludges*** E.O. 12866 and 13563 Review

Clarification Letters Issued After Promulgation of the NHSM Final Rule After promulgation of the 2011 NHSM final rule, a number of questions were raised regarding certain issues, including whether the EPA was changing its position regarding “contained gaseous materials” and whether they are solid wastes when burned in combustion units. While there was no regulatory text or discussion in the preamble to the final NHSM rule, the Agency*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 107 of 382 did respond to several comments that were submitted to the EPA during the comment period. Specifically, its response to the fourth comment in part 3b. I3 of the document entitled, “Responses to Comments Document for the Identification of Non
Hazardous Secondary Materials that are Solid Waste (February 2011),” 12 created concerns among the regulated community that the Agency had changed a long
- standing inte rpretation of what constitutes a “contained gaseous material” for purposes of defining the term solid waste under RCRA. In a letter sent to the American Forest and Paper Association, the EPA clarified that it was not changing its previous interpretations and that such interpretations still were the Agency’s position. 13 Specifically, as we state in the letter, “EPA was responding to a comment requesting that we include in the NHSM final rule a definition of ‘contained gaseous material.’ The Agency does not believe that including such a definition in the rule is necessary. However, our response seems to have caused confusion about whether the Agency was changing its prior interpretations regarding the burning of gaseous materials, for example in fume inciner ators, and whether or not such burning is considered to be treatment of a solid

We clarify here that the Agency’s previous statements and interpretations remain effective. Thus, burning of gaseous material, such as in fume incinerators (as well as other combustion units, including air pollution control devices that may combust gaseous material) does not involve treatment or other management of a solid waste (as defined in RCRA sectio n 1004(27).” Thus, we are stating again in the preamble to today’s proposed rule that we are not changing any of our previous interpretations as it relates to whether “contained gaseous material” is a solid waste. In addition to this letter, the Agency h as also issued a number of other letters in which we clarify how the 2011 NHSM final rule addresses certain materials or activities. For example, the EPA has issued clarification letters covering the following materials and issues: (1) July 21, 2011, lette r to Pamela F. Faggert, Dominion Resources Services, regarding materials that are used in recirculation/reinjection processes and CBO units; (2) August 5, 2011, letter to Sue Briggum, Waste Management, regarding landfill gas; (3) August 5, 2011, letter to Tracey Norberg, Rubber Manufacturers Association, regarding off

-Waste Petitions The 2011 NHSM final rule established a non
- waste determinat ion process that provides persons with an administrative petition process for receiving a formal determination from the EPA Regional Administrator that a NHSM that is used as a fuel, and which is not managed within the control of the generator, can be cons idered a non
- waste fuel provided they are able to demonstrate that such material has not been discarded and is indistinguishable in all relevant aspects from a fuel product. (40 CFR 241.3(c)). As discussed in the March 21, 2011 final rule (76 FR 15471), EPA has not arbitrarily determined that secondary materials transferred between companies are wastes. Instead, EPA examined a number of specific recycled materials, both within the control of the generator and transferred to a third party for recycling and decided that materials are to be considered solid wastes except in certain instances described in 40 CFR 241.3(b). These determinations were based on the record available to EPA. In order to better reflect the evidentiary*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 110 of 382 record, EPA is proposing to amend the language of 40 CFR 241.3(a) to state that except for materials described in 241.3(b), and newly proposed section 241.4, combusted non
hazardous secondary materials are “presumed” to be solid wastes. This petition process provides an opportunity under 40 CFR 241.3(c) for companies to show that their materials are not wastes. The petition process is essential because NHSMs are recycled and managed in many different ways and the Agency may lack the specific details in certain cases to know whether or not such NHSMs are o r are not waste (76 FR 15472). We believe that the petition process provides an important assurance to the community on waste status and relevant standards and also provides an opportunity to demonstrate that the part icular NHSM was not dis carded. The Agency solicits comment on the petition process as it relates this approach, and on whether or not the regulatory text should also be changed to address this situation as it relates to the petition process where such NHSM has not in fact been discarded. In evaluating whether to grant or deny the petition, the ultimate question that EPA will need to answer is whether or no t the NHSM has been discarded. If the applicant is able to demonstrate that such NHSM has not been discarded, including meetin g the legitimacy criteria, it is likely that the Agency*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 111 of 382 will grant the petition. Under the existing regulations, until EPA acts on such petition, the NHSM is considered to be a solid waste. However, we would note that if the NHSM has not been discarded, EPA’s grant of the petition would apply as of the date that the petitio n was submitted to the Agency. The Agency solicits comment on whether or not the regulatory text should also be changed to address this situation where such NHSM has not in fact been disc arded . Since promulgation of the 2011 NHSM final rule, concerns have been raised that the information required for a non
-waste determination petition would be extensive and the timeframe for issuance of the decision lengthy. The Agency wishes to clarify that we do not intend that the application required or the petition process itself to be burdensome or time and resource intensive for the applicant. As noted in the March 2011 final rule, the applicant must demonstrate that the NHSM that is to be burned as a fuel has not been discarded, is a legitimate product fuel (per § 241.3(d)(1)), considering the five criteria identified in § 241.3(c) (1) (i)
- (v): (1) Whether market par ticipants treat the non
- hazardous secondary material as a product rather than as a solid waste;*** E.O. 12866 and 13563 Review

hazardous secondary material is comparable to commercial fuels; 14 (3) Whether the non
- hazardous sec ondary material will be used in a reasonable time frame given the state of the market; (4) Whether the constituents in the non
- hazardous secondary material are released to the air, water or land from the point of generation to the point just prior to combustion of the secondary material at levels comparable to what would otherwise be released from traditional fuels; and (5) Other relevant factors. 15 Overall, applicants, in many cases can utilize existing information already in hand (e.g., laboratory an alysis data or process knowledge) rather than develop additional information specifically for the non
- waste determination petition. In addition, as noted in the previous footnote, there may already be a contractual or other written agreement between the generator of the NHSM and the combustion facility that burns

14 As discussed elsewhere in today’s proposal, EPA is clarifying that in making comparisons between the NHSM and the traditional fuel, the owner or operator can consider individual constituents or grouping of constituents. See section II.D.2 of this preamble for further discussion. 15 The Agency included this criterion to allow the applicant to make additional arguments that such NHSMs are a non - waste fuel. For example, if there is a contractual or other written agreement between the generator of the NHSM and the facility that combusts the NHSM that lays out how this material is to be handled or used as a fuel that may indicate how the material would meet the legitimacy criteria, this would be a relevant factor that EPA would consider in determining whether such NHSM is a non
- waste fuel.*** E.O. 12866 and 13563 Review

-waste fuel. As noted elsewhere in this preamble, EPA has collected contaminant data for various traditional fuels, which are available for use in meeting the contaminant legitimacy criterion as needed, to the extent that the applicant wants to utilize these data. 16 Potential applicants can include the generator of the NHSM, the facility that combusts the NHSM, an interested third party or a state agency (see FR 15530). Applications can also be submitted for a single combustor or a class of combustors, provided such combustion units are within the jurisdiction of the Regional Administrator. Useful information could also include a description of the nature of the relationship between the generator and the combustor, as well as a description of how the NHSM will be managed as it is transported off
- site and after it arrives at the combustor. We believe this type of information should be readily available to potential applicants.

16 EPA’s contaminant data are provided at the website for the NHSM rule at www.epa.gov/epawaste/nonhaz/define/index.htm However, as we have noted elsewhere, the applicant can rely on other data that they may have or become aware of.*** E.O. 12866 and 13563 Review

Rather, the Regional Administrator will evaluate the petition and issue a draft notice tentatively granting or denying the petition. Notification of the decisi on will be provided by local newspaper or radio. Public comment will be accepted for thirty days and a public hearing held upon request. A final decision will be issued after consideration of the comments as expeditiously as possible. In summary, we do not envision that the information submitted in a petition for a non
-waste determination would be more than is required for making a self
- determination that a NHSM is a non
- waste when burned within the control of the generator. However, because there ar e nearly 200,000 boilers and incinerators that can be used to burn such NHSMs, the EPA believes it is important that the Agency have the information necessary to ensure that the legitimacy criteria are met and that materials are not being discarded . The Agency requests comment on whether any other changes could be made to the non
waste determination petition process to streamline the process, while at the same time provide EPA with the opportunity to ensure that such NHSMs are not being discarded. For example, because the public has had the opportunity to comment on the*** E.O. 12866 and 13563 Review

- waste fuel, we are seeking comment on whether the Agency should further streamline the process by not seeking publi c comment on each individual petition. **D. Rationale for the Proposed Revisions to the Part 241 Requirements**  As noted above, the intent of this proposal is to identify certain specific aspects of the rule which EPA is reconsidering and on which it is so liciting public comment. The Agency is not reopening the entire rule for reconsideration and will not respond to comments directed toward rule provisions that are not specifically identified in this proposal. Thus, the Agency is not providing additional di scussion of the background or rationale for the NHSM rule in general. For a detailed discussion of the NHSM final rule, see 76 FR 15532

However, there was some confusion as to whether the definition included these materials. For example, questions arose whether the EPA would consider o rchard trees, vines and hulls, to be within the definition of clean cellulosic biomass (and, therefore, a traditional fuel) if the biomass material was not specifically listed within the regulatory definition. Consequently, we are proposing to revise the definition of “clean cellulosic biomass” in two ways: (1) to clarify that the list of biomass materials are examples within the definition and is not intended to be an exhaustive list, and (2) to provide a more comprehensive list of clean cellulosic biomass to guide the regulated community. Specifically, we are proposing to make the following revisions and additions to the definition: (1) explicitly acknowledge that the list of biomass materials is not exclusive by adding the phrase, “including, but not limited to”; (2) revise the category “forest
- derived biomass” to include*** E.O. 12866 and 13563 Review

- derived biomass; (4) add the category of “urban wood” and provide examples, i ncluding tree trimmings, stumps, and related forest
- derived biomass from urban settings (note that “urban wood” is limited to forest
- derived biomass from urban settings and does not include construction and demolition materials. Certain construction and demolition materials are included as a separate type of biomass within the definition of “clean cellulosic biomass”); (5) add more examples of types of crop residues (vines, orchard trees, hulls, seeds spent grains, cotton byproducts, corn and peanut product ion residues, rice milling and grain elevator operation residues); and (6) revise the category of “other biomass crops used specifically for energy production” to read as “other biomass crops used specifically for the production of cellulosic biofuels” and include “byproducts of ethanol natural fermentation processes” as an example of this type of biomass. These proposed revisions and additional examples more clearly recognize and describe the various categories of biomass materials that we consider to be within the definition of “clean cellulosic biomass” and, therefore, within the definition of traditional fuels. We believe that these additional examples*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 118 of 382 clearly meet the definition of clean cellulosic biomass, in that they will not contain contaminants a t concentrations not normally associated with virgin biomass materials. In fact, many of the examples being added in today’s proposal are themselves virgin materials (e.g., tree trimmings, stumps, orchard trees, etc.). We believe that providing these addit ional examples within the definition of clean cellulosic biomass is consistent with the intent of the 2011 NHSM final rule. Further, we believe that such revisions make it more clear that the types of biomass materials the Agency would consider to be withi n the definition of clean cellulosic biomass (and a traditional fuel) are not limited to those explicitly listed in the definition, as we believe that it would be impractical if not impossible to capture all types of biomass materials that can be used as fuels within this single definition. Thus, in today’s proposed rule, the EPA is proposing to revise the definition of “clean cellulosic biomass” as follows:

“ Clean cellulosic biomass means those residuals that are akin to traditional cellulosic biomass, in cluding, but not limited to: agricultural and forest
- derived biomass (e.g., green wood, forest thinnings, clean and unadulterated bark, sawdust, trim, tree harvesting residuals from logging and sawmill materials, hogged fuel, wood pellets, untreated wood p allets); urban wood*** E.O. 12866 and 13563 Review

These fuels are not secondary materials or solid wastes un less discarded. Clean biomass is biomass that does not contain contaminants at concentrations not normally associated with virgin biomass materials.” b. Contaminants In today’s action, we are proposing a number of changes to the definition of “contaminant s” in an effort to clarify what constituents are subject to the contaminant legitimacy criterion. The proposed definition is as follows: “ Contaminants means all pollutants listed in Clean Air Act sections 112(b) and 129(a)(4), with modifications outlined i n this definition to reflect constituents found in non
- hazardous secondary materials*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 120 of 382 prior to combustion. The definition includes the following elemental contaminants that commonly form Clean Air Act section 112(b) and 129(a)(4) pollutants: antimony, arsen ic, beryllium, cadmium, chlorine, chromium, cobalt, fluorine, lead, manganese, mercury, nickel, nitrogen, selenium, and sulfur. The definition does not include the following Clean Air Act section 112(b) and 129(a)(4) pollutants that are either unlikely to be found in
non - hazardous secondary materials prior to combustion or are adequately measured by other parts of this definition: hydrogen chloride (HCl), chlorine gas (Cl 2 ), hydrogen fluoride (HF), nitrogen oxides (NOx ), sulfur dioxide (SO 2 ), fine mineral fibers, particulate matter, coke oven emissions, diazomethane, white phosphorus, titanium tetrachloride, m
- cresol, o
- cresol, p
cresol, m
- xylene, o
- xylene, and p
- xylene. ” Before discussing these changes, we first want to note that the 2011 NHSM final rule and today’s proposed rule identify the same three ways a chemical can be labeled a contaminant. First, it may be one of the 187 HAP currently listed in CAA section 112(b); second, it may be one of the nine pollutants listed under CAA section 129(a)(4) ; and third, it may be one of a handful of chemicals whose combustion will result in the formation of listed CAA section 112(b) and section 129(a)(4) pollutants (e.g., sulfur that will result in SO 2 ). Today’s*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 121 of 382 proposed definition provides clarification by l isting the constituents that belong to the third group. 17 Specifically, several pollutants listed in CAA section 112(b) and section 129(a)(4) form during combustion, so elemental precursors to those pollutants that are found in the NHSM prior to combustion are being added to the contaminant definition in place of the pollutants themselves. For example, when present in a NHSM undergoing combustion, chlorine readily forms HCl, fluorine readily forms HF, nitrogen readily forms NOx , and sulfur readily forms SO 2 . Because forms of these four elements found in materials prior to combustion are not directly identified as CAA air pollutants, yet the forms they take due to combustion are directly identified as CAA air pollutants, we believe it would be less confusing t o include these elements in the “contaminants” definition. Also, we are proposing to exclude from the definition of contaminants those pollutants in the CAA sections 112(b) and 129(a)(4) lists that we do not expect to find in any NHSM. Specifically:

 H ydrogen chloride, Cl 2 , HF, NOx , and SO 2 are identified as CAA list pollutants that are excluded from the definition

17 Eleven metal elements directly identified in CAA section 112(b) are listed in the definition to provide the regulated community with a complete list of elements that are considered “contaminants” under the rule.*** E.O. 12866 and 13563 Review

 Fine mineral fibers are excluded because they are releases from the manufacturing and processing (not combustion) of
non - combustible rock, glass, or slag into mineral fibers;

 Particulate matter and coke oven emissions are excluded b ecause they are products of combustion unlikely to exist in NHSM prior to combustion;

 Cresol isomers m
- cresol, o
- cresol and p
- cresol are excluded because the listed pollutant cresols/cresylic acid includes these three isomers;

 Xylene isomers m
- xylene, o - xylene and p
- xylene are excluded because the listed pollutant xylenes includes these three isomers; and

 Diazomethane, white phosphorus and titanium tetrachloride are excluded because their high reactivity makes their presence in NHSMs very unlikely. I n addition, two phrases present in the 2011 NHSM final rule “contaminants” definition are not present in today’s

18 Carbon monoxide (CO) is unlikely to be fo und in solid or liquid NHSMs, and EPA expects that combustors can use process knowledge to justify not testing for CO in these cases. CO remains in the contaminants definition, however, because no clear surrogate exists to replace it

—neither the 2011 NHSM final rule nor today’s proposed rule considers the elements carbon and oxygen to be contaminants.*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 123 of 382 proposed definition. First, the phrase concerning constituents “that will result in emissions of air pollutants” has been removed since the regulated community appears to be confused that in determining whether or not a NHSM meets the “contaminant legitimacy criterion,” emissions from the combustion unit were to be considered in making the evaluation. The EPA disagrees and directs readers to the language in sections 241.3(d)(1)(iii) and 241.3(d)(2)(iv), which clearly states that the contaminant comparisons are based on the presence of contaminants in the NHSM that enters the combustion unit. Second, the phrase “including those constituents that could generate products of incomplete combustion,” also referred to as PICs, has been removed because it is duplicative and potentially misleading. Specifically, this phrase has been removed because all PICs that the Agency considers air pollutants

—includi ng dioxins, dibenzofurans, PCBs, and PAHs

—are already listed in CAA sections 112(b) or 129(a)(4) and are thus included in the “contaminants” definition. More importantly, it is potentially misleading because PIC formation depends heavily on combustion conditions, such as air/fuel ratio and mixing. These conditions are controlled to limit emissions, and neither these conditions nor emissions are the subject of this rule. The NHSM itself, and what it contains prior to combustion, is the subject of this*** E.O. 12866 and 13563 Review

Established Tire Collection Programs Under the 2011 NHSM final rule, whole scrap tires (that are removed from vehicles) had to be managed unde r an “established tire collection program” in addition to meeting other criteria in order to be considered a non
-waste fuel. The 2011 NHSM final rule defined “established tire collection program” as meaning “a comprehensive collection system that ensures s crap tires are not discarded and are handled as valuable commodities in accordance with section 241.3(b)(2)(i) from the point of removal from the vehicle through arrival at the combustion facility” (codified in 40 CFR 241.2). However, this definition doe s not directly account for “factory scrap” tires or “off
- specification” tires that are contractually arranged to be collected, managed and transported between a tire manufacturer (including retailers and other parties involved in the distribution and sale of new tires) and a combustor

—a fact pattern the Agency views as being within the intent of the regulatory definition of “established tire collection program” because the tires are not discarded. Thus, the Agency is proposing to define “established tire c ollection program” to mean “a comprehensive collection system or*** E.O. 12866 and 13563 Review

specification” tires in the 2011 NHSM final rule since information or comments were not provided to the EPA during the rulemaking process and thus, the Agency was not aware of the issue. The Agency did not receive comments about factory scrap or off
- specification tires on the ANPRM or the proposed rule. Following promulgation of the 2011 NHSM final rule, the EPA learned that off
- specification tires (including factory scrap tires), which include whole tires and tire components that do not meet manufacturer specifications, are colle cted at tire manufacturing facilities or manufacturer’s downstream distribution channels

—retailers and other parties involved in the distribution and sale of new tires. As noted in the revised definition, we interpret the term “tire manufacturers” broadly to include retailers and other parties that are involved in the distribution and sale of new tires, as we believe that these parties also manage tires as valuable commodities, such that*** E.O. 12866 and 13563 Review

If at any point in the process, a tire component or whole tire is not suitable for use as a vehicle tire, it is separated from the other tire components (or whole tires) and is stored in a protected environment in order to accumulate a sufficient quantity for shipment. The management of these tires is tightly controlled. Proprietary information could be collected by competitors by analyzing the factory scrap tire components, particularly from the uncured components (not yet vulcanized through heat and pressure), so the tires are stored in a safe manner, in part, to prevent theft. 19 Thus, we believe that factory scrap and off
- specification tires are handled in the same protective manner as those that qualified to be managed under the oversight of establ ished tire collection programs as described in the 2011 NHSM final rule. The tire manufacturers, as well as the manufacturers’ downstream distribution channels, that are included in the definition of “established tire collection programs” (1) have contra ctual arrangements with combustors, typically cement kilns (due to the high heating value and beneficial contribution to the cement production), to take and use their tires as fuels; or

As discussed in the 2011 NHSM final rule, the intent of the requirement for “removal from the vehicle” was to distinguish these tires from those that were previo usly abandoned, and thus discarded. The changes to the definition in this proposed rule align the codified definition of established tire collection programs with the intent of the definition. We also note that we are proposing to delete the reference to s ection 241.3(b)(2)(i) that was included in the previous definition of established tire collection programs, since the citation is no longer accurate based on other revisions being proposed today (e.g., see the discussion regarding scrap tires managed pursu ant to established tire collection programs in section II.D.3). Refer to the 2011 NHSM final rule for more background and information regarding the characterization of “established tire collection programs.” 20 2. Revisions to the Contaminant Legitimacy Cr iterion for NHSM Used as Fuels Several changes are being proposed in today’s rule to the contaminant legitimacy criterion for NHSM used as fuel.

First, today’s proposal replaces “contaminants” with the phrase “contaminants or groups of contaminants” to clarify that the regulatory definition allows groups of contaminants to be evaluated, where appropriate, in determining whether a NHSM meets the contaminant legitimacy criterion. Second, today’s proposal codifies language from the preamble of the 2011 NHSM final rule stating that the “designed to burn” concept includes traditional fuels that can be burned or are burned in a particular unit, whether or not the unit is permitted to burn that traditional fuel. In addition, the proposed regulations include text confirming that contaminant comparisons may use ranges from national surveys of traditional fuel data. Neither the 2011 NHSM final rule nor today’s proposed rule requires persons to compare contaminants in their NHSM to contaminants in the specific traditional fuel source they burn (or would otherwise burn). As an example, persons who would otherwise burn coal may use any
as -burned coal available in coal markets in making a comparison between the contaminan ts in their NHSM and the contaminants in coal

The first issue is that contami nant legitimacy criterion determinations do not require testing contaminant levels, in either the NHSM or an appropriate traditional fuel. Persons can use expert or process knowledge to justify decisions to rule out certain constituents. The second issue i s that persons may use data from a group of similar traditional fuels for contaminant comparisons, provided the unit could burn each traditional fuel. This idea grows from the “designed to burn” concept explained in the 2011 NHSM final rule and codified in today’s proposal, as it allows a person with a unit that can or does burn similar traditional fuels (e.g., anthracite, lignite, bituminous, and sub
-bituminous coal) to group those traditional fuels when making contaminant comparisons. See section II.D.2.b for more discussion of this rationale. a. What are the contaminants? While persons may satisfy the contaminant legitimacy criterion on a contaminant

Volatility, the presence of specific elements, and compound struc ture are three such properties. One approach to grouping contaminants, as shown in Tables 1 and 2 below, could include TOX, nitrogenated compounds, VOC, SVOC, D/F, PCB, PAH, and radionuclides. Persons may consider other groupings that they can show are technically reasonable. Grouping of contaminants is a standard practice often employed by the Agency as it develops regulations. In fact, the monitoring standards included in the CAA sections 112 and 129 regulations also utilize the grouping concept and they apply to the same combustion units impacted by the NHSM rule (i.e., industrial, commercial and institutional boilers and process heaters and CISWI units). For example,

 Volatile hydrocarbons and semi
- volatile hydrocarbons can both be expected to result from incomplete combusti on; therefore, the emission standards promulgated under the CAA regulations are grouped into one category: CO. 21

 Halogenated organics are expected to contribute to emissions of dioxin and acid gases (HCl and HF); therefore,

 Nitrogenated compounds are expected to contribute to emissions of NOx ; therefore, the emission standards promulgated under the CAA are grouped into one category: NOx . 23
A look at Tables 7 and 8 below also reveals that a number of the seemingly “individual” pollutants listed in sections 112 and 129 of the CAA are actually classes of structurally
- related compounds (e.g., PCBs, POM, D/F, cyanide compounds, cresols, glycol ethers, radionuclides , xylenes, antimony compounds, arsenic compounds, beryllium compounds, Cd compounds, etc.). If persons choose to group contaminants, analytical methods for the NHSM and traditional fuel should account for the same list of compounds to the extent possible . Persons may be able to exclude some members of a particular contaminant group from testing based on process knowledge, but methods for testing the group as a whole should generally account for all other members of the contaminant group. Some data sourc es may define contaminant groups more broadly than this rule, thus resulting in a definition for a

Such data sources may be all that is available in the literature in some cases, but they may still be appropriate. Total VOC and total SVOC analyses offer an instructive example because, depending on the test used and the material analyzed, such analyses may include concentrations of methane, acetone, or other compounds not co nsidered contaminants under the NHSM final rule. Several solutions exist to make the results meaningful, however. One approach would be to specifically subtract compounds like methane that are not considered contaminants under the rule and are expected to boost a total group count in traditional fuels. Another approach would be to measure each applicable compound individually and add the totals. The tables presented below would separate the list of potential contaminants into the 15 elements listed in today’s proposed definition of “contaminants” and the 163 compounds or groups of compounds inferred from that definition by their inclusion on the CAA sections 112 or 129 lists.

What does “designed to burn” mean? To meet the contaminant legitimacy criterion, persons must compare contaminants in the NHSM they wish to burn to contaminants in the traditional fuel the unit is “designed to burn.” 40 Today’s proposal codifies that data for any traditional fuel the unit can burn or does burn may be used for these comparisons, whether or not the unit’s air permit lists the traditional fuel. The reason such comparisons to traditional fuel(s) are conducted is to assist in making a determination of whether or not the NHSM is being discarded, which makes differentiating between “can burn” and “does burn” irrelevant. Please note that for a unit to be able to burn a traditional fuel, it needs an appropriate feed mechanism (e.g., a way to load solid fuel of a particular size into the unit).

“ Traditional fuels means materials that are produced as fuels and are unused products that have not been discarded and the refore, are not solid wastes, including: (1) fuels that have been historically managed as valuable fuel products rather than being managed as waste materials, including fossil fuels (e.g., coal, oil and natural gas), their derivatives (e.g., petroleum coke , bituminous coke, coal tar oil, refinery gas, synthetic fuel, heavy recycle, asphalts, blast furnace gas, recovered gaseous butane, and coke oven gas) and cellulosic biomass (virgin wood); and (2) alternative fuels developed from virgin materials that can now be used as fuel products, including used oil which meets the specifications outlined in 40 CFR 279.11, currently mined coal refuse that previously had not been usable as coal, and clean cellulosic biomass.

In other words, if a facility burns biomass in its combustion unit, but that same combustion unit could also burn coal, the facility could compare its secondary material to either traditional fuel.

The EPA lacks sufficient contaminan t data, however, to assist those wishing to compare NHSM to these traditional fuels. In addition, other units currently exist that burn only NHSMs. Both situations raise the question of what traditional fuel(s) to use for contaminant comparisons. In additi on to being able to burn derivative fuels, alternative fuels, or NHSM, most combustion units can also burn other traditional fuel(s). In such cases, it is appropriate to make the comparison to one of the traditional fuel categories discussed above: either coal or wood for solids or oil for liquids. For example, if a combustion unit only burns a solid form of NHSM, the combustor could compare contaminants in the NHSM against either coal or wood in order to demonstrate compliance with the contaminant legitima cy criterion, provided the combustion unit is designed to burn such solid forms of fuel. c.

Examples of acceptable NHSM data could include both laboratory test results from a specific generator or combustor and i ndustry

Given data for a particular traditional fuel, it makes intuitive sense to base the traditional fuel comparison value on the upper end of its statistical range.

It would not be appropriate to compare an average NHSM contaminant valu e to the high end of a traditional fuel range, as the existence of an average implies multiple data points from which a more suitable statistic (e.g., range or standard deviation) could have been calculated. If each NHSM comparison value is comparable to or lower than its corresponding traditional fuel value, the material would be considered to meet the contaminant legitimacy criterion. An initial assessment would not generally need to be repeated, provided the facility continues to operate in the same
manner and use the same type of NHSMs as when the original assessment was made. We would finally note that despite presenting several approaches for calculating NHSM comparison values, such as the upper end of a statistical range or a calculation involving the mean and standard deviation, today’s preamble discussion does not preclude other reasonable methodologies.

Such additional factors may in clude, but are not limited to, whether the NHSM’s use as a fuel has been integrally tied to the industrial production process and the extent to which the NHSM is functionally the same as the comparable traditional fuel. We note that a balancing approach t o considering the legitimacy criteria along with other relevant factors is not included in the standards and procedures for making individual

The information and rationale that the Agency is relying upon to propose the section 241.4 categorical determinations for certain secondary materials is discussed below. a. Scrap Tires In the 2011 NHSM final rule, the EPA determined that scrap tires removed from vehicles and managed pursuant to established tire collection programs would not be considered a solid waste, provided they meet the legitimacy criteria in §241.3(d)(1). The 2011 NHSM final rule preamble also concluded that, as a category, scrap tir es managed pursuant to established tire collection programs would meet the legitimacy criteria for NHSMs used as fuels. Questions have arisen, however, as to whether persons must still demonstrate for each facility that this material meets the legitimacy c riteria. To clarify this point, we are proposing to codify a categorical determination in today’s rule to designate scrap tires that have not been discarded and are managed under the oversight of established tire collection programs (as defined in 241.2), including tires removed from vehicles and off
- specification tires, are not solid wastes when used as fuels in combustion units. Thus, persons who generate and/or burn such scrap tires would not need to make an*** E.O. 12866 and 13563 Review

non - waste fuels. As discussed in section II.D.1 of today’s action, the term “established tire collection program” is proposed to encompass off
- specification tires (including factory scrap tires) that are contractually arranged to be collec ted, managed and transported between a tire manufacturer, including retailers or other parties involved in the distribution and sale of new tires, and a combustor. Thus, under the proposal, “established tire collection program” means “a comprehensive colle ction system or contractual arrangement that ensures scrap tires are not discarded and are handled as valuable commodities through arrival at the combustion facility.” The established tire collection programs ensure the tires are not discarded. The rationa le for the related edits to the definition of established tire collection programs are described in the section II.D.1. As discussed in the 2011 NHSM final rule, s crap tires from vehicles meet the legitimacy criteria (§241.3(d)(1)) for being handled as a valuable commodity, for having meaningful heating value, and for comparable contaminants. 50 Specifically, scrap tires are considered to be handled as a valuable commodity when they are collected under established tire collection programs.

In fact, the heating value of scrap tires is higher than typical coal values and other solid fue ls. 51 In developing the 2011 NHSM final rule, the EPA analyzed contaminant concentrations in scrap tires and determined that contaminant levels were comparable to or lower than levels in traditional fuels; therefore, scrap tires are considered to meet the l egitimacy criterion for comparable contaminants. 52 The term “scrap tire” is a general term for tires and can include, for example, whole tires, chipped tires, off

Resinated Wood 53 The EPA is proposing to designate resinated wood as not being a solid waste when used as a fuel. This determination was previously codified under §241.3 (b)(2)(ii) of the NHSM final rule, provided the resinated wood met the legitimacy criteria in §241.3(d)(1). However, based on the available information, as well as how this material is handled and used in the process, resinated wood is not being discarded when used as a fue l, and thus, should not be considered a solid waste when burned as a fuel.As discussed in the 2011 NHSM final rule, wood product plants have been designed to specifically utilize these residuals that the wood manufacturing process creates and would not b e able to operate as designed without this material. For example, sander dust injector systems have been specifically developed to accommodate the unique combustion requirements of

—thus, the cost of these residual materials relative to the cost of using other fuels would be a major consideratio n. 55 Overall, in composite panel manufacturing, plants typically reuse 58 percent of these residual materials in the process and 35 percent is burned for energy recovery. 56 Resinated wood is highly valued within the wood products industry for its high fuel value relative to other wood fuels generated and burned at these facilities for energy recovery. Many facilities rely on mixing of these low moisture content wood materials with higher moisture materials. Resinated wood residuals are routinely transferred between either intra

For direct fired dryers alone, the cost to switch from sander dust to natural gas r anged from $350,000 to $1.4 million a year, again depending on dryer size and gas prices. These costs do not include the re

- site is used and handled in the same manner that resinated wood residuals are used when generated on
site. In general, the motivation to use the resinated wood as a fuel, even with the slightly higher formaldehyde levels, predominates over the motivation to dispose of the formaldehyde. See American Petroleum Institute v. EPA , 216 F.3d 50, 58 (DC Cir. 2000) (in declaring reclaimed oily wastewater to be a waste, the EPA failed to explain why the discard motivation predominated the recycling motivation). Indeed, discard of the formaldehyde is a very distant second to the fuel product use of the resinated wood. The heating value range presented (8,500

– 9,000 Btu/lb) indicates that resinated wood residuals have heating values significantly greater than the 5, 000 Btu/lb level described in the preamble to the 2011 NHSM final rule for presuming compliance with the meaningful heating value legitimacy criterion (codified at §241.3(d)(1)(ii)) . Resinated wood residuals also are managed as a valuable commodity since these residuals are managed as a primary fuel for wood products manufacturers.

In addition, new national rules, as mandated by the CARB Composite Wood ATCM, per new Public Law No. 111

- waste determination for resinated wood that is used as fuel. We are propo sing to codify this determination, balancing the legitimacy criteria and other relevant factors based on the fact that resinated wood residuals that are used as fuels represents an integral component to the wood manufacturing process and, as such, resinate d wood residuals are not being discarded when burned as fuels. That is, the purpose of burning these wood residuals (including the resins that they contain, which themselves contribute to the heating value of the material) is not to destroy or discard them , as they are clearly considered and managed as a valuable commodity to the manufacturing process.

57 Information received from the wood manufacturing industry indicates that formaldehyde levels will be reduced to less than 100 ppm in resinated wood based o n the new CARB rules. These data are provided in the docket for today’s proposed rule.*** E.O. 12866 and 13563 Review

We also note the prevalence of wood product plants that have been designed specifically to utilize these residuals for their fuel value; in fact, many (if not most) wood products plants would not be able to operate as designed without the use of these materials as fuel. Thus, resinated wood residuals are not being discarded when used as fuel and, therefore, we are proposing to specifically identify them as a non

The section 260.20 standards reflect normal, informal rulemaking procedures under the APA and thus serve as an appropriat e model for the NHSM petitions under this section. In the context of a rulemaking petition under section 241.4(b), any person would be able to petition the Administrator for a regulatory amendment to identify and request that additional NHSMs be included on the list of materials in section 241.4(a) that are not solid wastes when used as a fuel in a combustion unit.

By listing thes e NHSMs categorically, persons would not have to make individual determinations as to whether or not these NHSMs are solid wastes. In addition, the Agency is also proposing that in considering whether or not to list a NHSM as a
non - waste fuel, that the Age ncy can balance the legitimacy criteria, and such other relevant factors that the Administrator may identify. Such additional factors may include, but are not limited to, whether the NHSM’s use as a fuel has been integrally tied to the industrial productio n process and the extent to which the NHSM when used as a fuel is consistent with that of fuel product. With regard to pulp and paper sludges, the 2011 NHSM final rule specifically concluded the following “The final rule will retain the proposed approach

In this section, we discuss the informat ion we currently have on these sludges, and the additional information that the Agency needs before we could categorically list these materials in section 241.4(a) as a non
waste fuel. If such information is provided to the EPA, and after balancing the leg itimacy criteria with other relevant factors that the EPA believes that these sludges are not solid wastes when combusted, the EPA is prepared to add pulp and paper sludges to the list of non
-waste fuels in section 241.4(a). Pulp and paper mill sludges, b oth primary and secondary, are produced from the wastewater treatment of process effluents. In the pulping and papermaking process, maximizing wood fiber recovery is essential in making the process efficient and cost
effective. However, there are fibers th at end up being too short (fines) that can be detrimental to paper quality and that inhibit the papermaking capacity of the paper machine. Mills thoroughly clean and screen the wood fibers to retain the suitable fibers and remove the excess fines. These fi nes end up in the wastewater stream and, eventually, in the sludge. Therefore, these sludges, which are approximately 90
- 95 percent biomass on a dry weight basis, are essentially no different than the biomass

The EPA compared the contaminant concentrations in pulp and paper sludges to levels found in coal and untreated wood, since both these traditional fuels can be burned in pulp and paper mills. As we discussed in the preamble to the final NHSM rule, chlorine levels from one set of pulp and paper sludge samples submitted in the public comments had an arithmetic mean of 465 ppm, a median of 318 ppm, a maximum level among mill means of 2,399 ppm, and a maximum among individual analyses of 4,800 ppm (all on a dry weight basis). Other samples had chlorine concentrations of between 1 ,050
- 4,800 ppm (dry basis). When comparing information on pulp and paper sludge to the information that we have compiled on coal, we found that chlorine levels in coal are reported to be as high as 7,400 ppm, and that average chlorine values for bituminous and sub
bituminous coal are 1,200 ppm and 140 ppm, respectively. Thus, the average chlorine levels reported in most pulp and paper sludge are likely to be comparable with average chlorine levels found in bituminous coal. We also determined that the chlori ne levels in pulp and paper sludge would be comparable to untreated*** E.O. 12866 and 13563 Review

conc entration of 16,550 ppm. However, since this was the only sample with such a high concentration of chlorine, we did not think that it was representative of pulp and paper sludges generally. Since promulgation of the 2011 NHSM final rule, EPA has received a dditional contaminant data regarding these pulp and paper sludges from the forest products industry, which demonstrate even more clearly that this one sample is anomalous. Regarding chlorine levels in particular, the forest products industry provided data for 93 samples of pulp and paper sludges. This data set shows the mean value for chlorine to be 361 ppm, with a standard deviation of 661 ppm, and a 90 percent confidence interval at 1,217 ppm. We also determined that the levels of metals were lower in pulp and paper sludges than in both untreated wood and coal. Such data further support the conclusions outlined in the final NHSM rule that, based on

Contaminant data have also been reorganized to better reflect revisions to the definition of “contaminants” and the contaminant legitimacy criterion in today’s proposed NHSM rule.

While pulp and paper sludges can have a heating value below 5,000 Btu/lb, pulp and paper mills typically improve the heating value through dewatering. Data from the Boiler/CISWI database established for those rules indicate that Btu/lb values exce eded 5,000 Btu/lb for pulp and paper sludge measured on a dry weight basis. Thus, we believe that pulp and paper sludges meet the meaningful heating value legitimacy criterion when dewatered. Also, since pulp and paper sludges are handled promptly (i.e.,

To the extent industry and other commenters believe that these pulp and paper sludges should be categorically listed in section 241.4(a), they will need to provide the Agency with appropriate information, as discussed later in this section. In such instances, the Agency can list a NHSM as a non

Coal Refuse Coal refuse is generated when coal is mined, and is comprised of no n - combustible rock with some attached carbon material that is not easily separated due to its small size. The EPA‘s Coal Refuse Materials Characterization Paper indicates that there are 18 coal refuse plants (Fossil Fuel Electric Power Generation

After reaffirming that EPA has determined that currently
generated coal refuse is an alternative fuel, EPA addressed coal refuse from legacy piles. While noting that coal refuse from legacy piles “...has clearly been discarded and is a solid waste unless sufficiently processed into a new legitimate fuel product,” EPA also states that it has determined that such refuse is processed no differently than currently generated coal refuse, and therefore meets EPA‘s requ irements for processing under 40 CFR 241.2. The EPA goes on to declare that post
processed coal refuse from legacy piles meets the first two criteria for treatment as a non
-waste fuel when combusted: materials are managed in the same manner, and would have similar heating values, as currently generated coal refuse, which is a traditional fuel. The EPA then addresses the third criterion

—whether the material contains contaminants at levels comparable to or lower than traditional fuels. The EPA affirms that b ecause currently

- generated coal refuse, EPA expects that post
-processed coal refuse from legacy piles satisfies EPA‘s contaminant legitimacy criterion. Thus, post
-processed coal refuse from legacy piles are not being discarded when used as fuel and, ther efore, we are taking comment on specifically identifying them as a non
- waste fuel in §241.4. **F. Effect of This Proposed Rule on Other Programs**  1. Clean Air Act During the 2011 NHSM final rulemaking, the EPA assessed the effects of that final rule on othe r programs. See 76 FR 15545
- 15546. The reconsideration proposals for the CISWI and boiler rules are consistent with the proposed revisions. These proposed NHSM revisions resulted in only minimal changes to the inventories for CISWI and boilers. 2. Subtitl e C Hazardous Waste Program/Definition of Solid Waste Rule The result of this rule will have no effect on the RCRA subtitle C hazardous waste program because it does not address hazardous waste. The RCRA subtitle C hazardous waste federal program has a lo ng regulatory history in defining “solid waste”*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 169 of 382 for purposes of the hazardous waste regulations. However, the 40 CFR 261.2 definition of solid waste explicitly applies only to wastes that also are hazardous for purposes of the subtitle C regulations (see 4 0 CFR 261.1(b)(1)). Section 129 of the CAA also specifically excludes subtitle C combustion units from coverage under that section. Section 7003 of the RCRA gives the EPA the authority to compel actions to abate conditions that may present an “imminent and substantial endangerment” involving both solid and hazardous wastes. The EPA uses this authority on a case
-by
- case basis. The Agen cy can determine in a specific factual context whether a NHSM causes an imminent and substantial endangerment to human health and the environment. Also, RCRA sections 3007 and 3008 establish the EPA’s inspection and federal enforcement authority to address violations of the subtitle C hazardous waste regulations. Nothing in this rule shall impact the EPA’s ability to act pursuant to RCRA sections 3007, 3008 and 7003. The rule also does not limit or otherwise affect the EPA's ability to pursue potentially re sponsible persons under section 107 of CERCLA for releases or threatened releases of hazardous substances. **G.

– Do Not Cite, Quote, or Release During Review *** Page 170 of 382 This proposal does not change the relationship to state programs as described in the 2011 NHSM final rule. Refer to section IX of the 2011 NHSM final rule (76 FR 15546) for the discussion on state authority including: “Applicability of State Solid Waste Definitions and Beneficial Use Determinations” and “Clarifications on the Relationship to State Programs.” The Agency, however, would like to reiterate a few points. Section 129 of the CAA states that the term “solid waste” shall have the meaning “established by the Administrator pursuant to [RCRA].” Consequently, the EPA issued the final NHSM rul e to provide a definition of “solid waste” under RCRA in order to determine which NHSMs would be subject to the emissions standards under sections 112 and 129 of the CAA. In short, if a NHSM is not a “solid waste” under RCRA, and is burned in a combustion unit, then the combustion unit that burns the material would be subject to the applicable CAA section 112 requirements. On the other hand, if the NHSM is considered a “solid waste,” then the combustion unit that burns the material would be subject to the applicable CAA 129 requirements, even if energy or material recovery also occurs. The part 241 waste determination only applies to those NHSMs that are combusted and does not address other uses.*** E.O. 12866 and 13563 Review

State Adoption of the Rulemaking No federal approval procedures for state adoption of today's proposed rule are included in this rulemaking action under RCRA subtitle D. Although the EPA does promulgate criteria for solid waste landfills and approves state MSW landfill p ermitting programs, RCRA does not provide the EPA with authority to approve state programs beyond MSW landfill permitting programs. While states are not required to adopt regulations promulgated under RCRA subtitle D, some states incorporate federal regula tions by reference or have specific state statutory requirements that their state program can be no more stringent than the federal regulations. In those cases, the EPA anticipates that, if required by state law, the changes being proposed today, if finali zed, will be incorporated (or possibly adopted by authorized state air programs) consistent with the state’s laws and administrative procedures. **H.

Paperwork Reduction Act This proposed rule does not impose any new information collection burden. However, OMB has previously approved the information collection requirements contained in the existing CISWI and NHSM 62 regulations (40 CFR part 60, subparts CCCC and DDDD, and 40 CFR part 241) under the provisions of the PRA, 44 U.S.C. 3501, et seq ., and has been assigned EPA ICR number 2384.03 for subpart CCCC, 40 CFR part 60, EPA ICR number 2385.03 for subpart DDDD, 40 CFR part 60, and EPA ICR number 2382.03 for 4 0 CFR part 241. This action is believed to result in no changes to the information collection requirements of the final NHSM rule and will have no impact on the information collection estimate of project cost and hour burden made and approved by OMB. Due to changes in the CISWI inventory and monitoring requirements of the CISWI rule, the information collection estimate of project cost and hour burden have been revised. Therefore, only the CISWI ICR has been revised. The OMB control numbers for the EPA’s re gulations in 40 CFR are listed in 40 CFR part 9. C. Regulatory Flexibility Act

Small entities include small businesses, small organizations and small governmental jurisdictions. For purposes of asses sing the impacts of the rule on small entities, small entity is defined as: (1) A small business as defined by the SBA’s regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or s pecial district with a population of less than 50,000; or (3) a small organization that is any not

After considering the economic impacts of this proposed rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. This proposed rule will not impose any new requirements on any entities because it does not impose any additional regulato ry requirements relative to those specified in the March 2011 final CISWI and NHSM rules.

We continue to be interested in the potential impacts of the proposed rule on small entities and welcome comments on issues related to such impacts. D.

It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132.

However, any indirect NHSM impacts that may occur as a result of the CISWI action are expected to be negligible due to the very limited focus of the CISWI part or this rule. Thus, Executive Order 13175 does not apply to this action. The EPA specifically solicits additional comment on this proposed action from tribal officials. G. Executive Order 13045: Protection of Chi ldren from Environmental Health Risks and Safety Risks The EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying to those regulatory actions that concern health or safety risks, such that the analysis required under section 5

-burning kiln subcategories to modify existing air pollution control devices (e.g., increase the horsepower of thei r wet scrubbers) or install and operate new control devices, resulting in approximately 242,283 MW
- hours per year of additional electricity being used. Given the negligible change in energy consumption expected to result from this rule, the EPA does not e xpect any significant price increase for any energy type. The cost of energy distribution should not be affected by this rule at all since the rule would not affect energy distribution facilities. We also expect that any impacts on the import of foreign en ergy supplies, or any other adverse outcomes that may occur with regards to energy supplies, would not be significant. We, therefore, conclude that if there were to be any adverse energy effects associated with this rule, they would be minimal. I. Nationa l Technology Transfer and Advancement Act Section 12(d) of the NTTAA of 1995, Public Law No. 104
- 113, 12(d) (15 U.S.C. 272 note) directs the EPA to use VCS in its regulatory activities, unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials*** E.O. 12866 and 13563 Review

– Do Not Cite, Quote, or Release During Review *** Page 179 of 382 specifications, test methods, sampling procedures, and business practices) that are developed or adopted by VCS bodies. The NTTAA directs the EPA to provide Congress, thro ugh OMB, explanations when the agency decides not use available and applicable VCS. This proposed rulemaking does not involve any revisions to the technical standards or test methods required in the final CISWI rule. Therefore, the EPA did not reconsider the use of any VCS for this proposal. J. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and Low
- Income Populations Executive Order 12898 (59 FR 7629, February 16, 1994) establishes federal executive policy on EJ. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make EJ part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental eff ects of their programs, policies and activities on minority populations and low
- income populations in the United States. The EPA has determined that this proposed rule will not have disproportionately high and adverse human health or environmental effects on minority or low
- income populations*** E.O. 12866 and 13563 Review

– Draft

– Do Not Cite, Quote, or Release During Review *** Page 180 of 382 because it increases the level of environmental protection for all affected populations without having any disproportionately high and adverse human health or environmental effects on any population, including any mino rity or low
- income population. The amendments do not relax the control measures on sources regulated by the CISWI rule, and, therefore, will not cause emissions increases from these sources. The March 2011 final CISWI rule will reduce emissions of all the listed HAP emitted from this source. Furthermore, the targeted revisions proposed in the NHSM section of this rule are designed to improve the management of these materials, thereby helping to further ensure against any disproportionately high and adverse human health or environmental effects on minority or low

a claim for civil penalties for exceedances of such standards that are caused by malfunction, as defined at 40 CFR 60.2. Appropriate penalties may be assessed, however, if you fail to meet your burden of proving all of the requirement s in the affirmative defense. The affirmative defense shall not be available for claims for injunctive relief. (a) To establish the affirmative defense in any action to enforce such a limit, you must timely meet the notification requirements in paragraph ( b) of this section, and must prove by a preponderance of evidence that: (1) The excess emissions: (i) Were caused by a sudden, infrequent, and unavoidable failure of air pollution control and monitoring equipment, process equipment, or a process to operat e in a normal or usual manner; and (ii) Could not have been prevented through careful planning, proper design or better operation and maintenance practices; and (iii) Did not stem from any activity or event that could have been foreseen and avoided, or planned for; and (iv) Were not part of a recurring pattern indicative of inadequate design, operation, or maintenance; and (2) Repairs were made as expeditiously as possible when the applicable emission limitations were being exceeded. Off
- shiftPage 196 of 382

and overtime labor were used, to the extent practicable to make these repairs; and (3) The frequency, amount and duration of the excess emissions (including any bypass) were minimized to the maximum extent practicable during periods of such emissions; and (4) If the ex cess emissions resulted from a bypass of control equipment or a process, then the bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; and (5) All possible steps were taken to minimize the impact of the excess emissio ns on ambient air quality, the environment and human health; and (6) All emissions and/or parameter monitoring and systems, as well as control systems, were kept in operation if at all possible, consistent with safety and good air pollution control practic es; and (7) All of the actions in response to the excess emissions were documented by properly signed, contemporaneous operating logs; and (8) At all times, the facility was operated in a manner consistent with good practices for minimizing emissions; and (9) A written root cause analysis has been prepared, the purpose of which is to determine, correct, and eliminate the primary causes of the malfunction and the excess emissionsPage 197 of 382

resulting from the malfunction event at issue. The analysis shall also specify, using best monitoring methods and engineering judgment, the amount of excess emissions that were the result of the malfunction. (b) Notification. The owner or operator of the facility experiencing an exceedance of its emission limit(s) during a malfuncti on shall notify the Administrator by telephone or facsimile (FAX) transmission as soon as possible, but no later than two business days after the initial occurrence of the malfunction, if it wishes to avail itself of an affirmative defense to civil penalti es for that malfunction. The owner or operator seeking to assert an affirmative defense shall also submit a written report to the Administrator within 45 days of the initial occurrence of the exceedance of the standard in §60.2105 to demonstrate, with all necessary supporting documentation, that it has met the requirements set forth in paragraph (a) of this section. The owner or operator may seek an extension of this deadline for up to 30 additional days by submitting a written request to the Administrator before the expiration of the 45 day period. Until a request for an extension has been approved by the Administrator, the owner or operator is subject to the requirement to submit such report within 45 days of the initial occurrence of the exceedance. 16.

Opacity means the degree to which emissions reduce the transmission of light and obscure the view of an obje ct in the background. Operating day means a 24
- hour period between 12:00 midnight and the following midnight during which any amount of solid waste is combusted at any time in the CISWI unit. Oxygen analyzer system means all equipment required to determine the oxygen content of a gas stream and used to monitor oxygen in the boiler flue gas or firebox. This definition includes oxygen trim systems. The source owner or operator is responsible to install, calibrate, maintain, and operate the oxygen analyzer sys tem in accordance with the manufacturer’s recommendations. Oxygen trim system means a system of monitors that is used to maintain excess air at the desired level in a combustion device. A typical system consists of a flue gas oxygen and/or carbon monoxide monitor that automatically provides a feedback signal to the combustion air controller.

* * * * *Page 259 of 382

Performance evaluation means the conduct of relative accuracy testing, calibration error testing, and other measurements used in validating the continuous mo nitoring system data. Performance test means the collection of data resulting from the execution of a test method (usually three emission test runs) used to demonstrate compliance with a relevant emission standard as specified in the performance test secti on of the relevant standard. Process change means a significant permit revision, but only with respect to those pollutant
- specific emission units for which the proposed permit revision is applicable, including but not limited to a change in the air polluti on control devices used to comply with the emission limits for the affected CISWI unit (e.g., change in the sorbent used for activated carbon injection).

* * * * * Raw mill means a ball and tube mill, vertical roller mill or other size reduction equipment, that is not part of an in
line kiln/raw mill, used to grind feed to the appropriate size. Moisture may be added or removed from the feed during the grinding operation. If the raw mill is used to remove moisture from feed materials, it is also, by definition, a raw materialPage 260 of 382

dryer. The raw mill also includes the air separator associated with the raw mill.

* * * * * Small, remote incinerator means an incinerator that combusts solid waste (as that term is defined by the Administrator in 40 CFR part 241) and combusts 3 tons per day or less solid waste and is more than 25 miles driving distance to the nearest municipal solid waste landfill. Soil treatment unit means a unit that thermally treats petroleum contaminated soils for the sole purpose of site remediation. A soil treatment unit may be direct
- fired or indirect fired. A soil treatment unit is not an incinerator, waste -burning kiln, an energy recovery unit or a small, remote i ncinerator under this subpart. Solid waste incineration unit means a distinct operating unit of any facility which combusts any solid waste (as that term is defined by the Administrator in 40 CFR part 241) material from commercial or industrial establishments or the general public (including single and multiple residences, hotels and motels). Such term does not include incinerators or other units required to have a permit under section 3005 of the Solid Waste Disposal Act. The term "solid waste incineratio n unit" does not include: (A) materials recovery facilities (including primary or secondary smelters) which combust waste for thePage 261 of 382

primary purpose of recovering metals; (B) qualifying small power production facilities, as defined in section 3(17)(C) of the Federal Power Act (16 U.S.C. 769(17)(C)), or qualifying cogeneration facilities, as defined in section 3(18)(B) of the Federal Power Act (16 U.S.C. 796(18)(B)), which burn homogeneous waste (such as units which burn tires or used oil, but not including refuse - derived fuel) for the production of electric energy or in the case of qualifying cogeneration facilities which burn homogeneous waste for the production of electric energy and steam or forms of useful energy (such as heat) which are used for industrial , commercial, heating or cooling purposes; or (C) air curtain incinerators provided that such incinerators only burn wood wastes, yard wastes, and clean lumber and that such air curtain incinerators comply with opacity limitations to be established by the Administrator by rule. Space heater means a usually portable appliance for heating a relatively small area. A space heater is not an incinerator, waste -burning kiln, an energy recovery unit or a small, remote incinerator under this subpart.

* * * * * Waste -burning kiln means a kiln that is heated, in whole or in part, by combusting solid waste (as that term is defined by the Administrator in 40 CFR part 241). A waste -burning kiln doesPage 262 of 382

not include a kiln that is feeding non
- hazardous secondary ingredients ex clusively into the cold end of the kiln. Wet scrubber means an add
- on air pollution control device that uses an aqueous or alkaline scrubbing liquor to collect particulate matter (including nonvaporous metals and condensed organics) and/or to absorb and n eutralize acid gases.

(5) A discussion identifying the frequency and methods for recalibrating the instruments you will use for monitoring these parameters. (b) [Reserved] 59. Section 60.2685 is revised to read as follows: §60.2685 Affirmative Defense for Exceedance of an Emission Limit During Malfunction In response to an action to enforce the standards set forth in paragraph §60.2670 you may assert an affirmative defense to a claim for civil penalties for exceedances of such standards that are caused by malfunction , as defined at §60.2. Appropriate penalties may be assessed, however, if you fail to meet your burden of proving all of the requirements in the affirmative defense. The affirmative defense shall not be available for claims for injunctive relief.Page 294 of 382

(a) To es tablish the affirmative defense in any action to enforce such a limit, you must timely meet the notification requirements in paragraph (b) of this section, and must prove by a preponderance of evidence that: (1) The excess emissions: (i) Were caused by a sudden, infrequent, and unavoidable failure of air pollution control and monitoring equipment, process equipment, or a process to operate in a normal or usual manner; and (ii) Could not have been prevented through careful planning, proper design or better operation and maintenance practices; and (iii) Did not stem from any activity or event that could have been foreseen and avoided, or planned for; and (iv) Were not part of a recurring pattern indicative of inadequate design, operation, or maintenance; and (2) Repairs were made as expeditiously as possible when the applicable emission limitations were being exceeded. Off
- shift and overtime labor were used, to the extent practicable to make these repairs; and (3) The frequency, amount and duration of the exc ess emissions (including any bypass) were minimized to the maximum extent practicable during periods of such emissions; andPage 295 of 382

(4) If the excess emissions resulted from a bypass of control equipment or a process, then the bypass was unavoidable to prevent los s of life, personal injury, or severe property damage; and (5) All possible steps were taken to minimize the impact of the excess emissions on ambient air quality, the environment and human health; and (6) All emissions and/or parameter monitoring and syst ems, as well as control systems, were kept in operation if at all possible, consistent with safety and good air pollution control practices; (7) All of the actions in response to the excess emissions were documented by properly signed, contemporaneous oper ating logs; and (8) At all times, the facility was operated in a manner consistent with good practices for minimizing emissions; and (9) A written root cause analysis has been prepared, the purpose of which is to determine, correct, and eliminate the prima ry causes of the malfunction and the excess emissions resulting from the malfunction event at issue. The analysis shall also specify, using best monitoring methods and engineering judgment, the amount of excess emissions that were the result of the malfunc tion.Page 296 of 382

(b) Notification . The owner or operator of the facility experiencing an exceedance of its emission limit(s) during a malfunction shall notify the Administrator by telephone or facsimile (FAX) transmission as soon as possible, but no later than two bu siness days after the initial occurrence of the malfunction, if it wishes to avail itself of an affirmative defense to civil penalties for that malfunction. The owner or operator seeking to assert an affirmative defense shall also submit a written report t o the Administrator within 45 days of the initial occurrence of the exceedance of the standard in §60.2670 to demonstrate, with all necessary supporting documentation, that it has met the requirements set forth in paragraph (a) of this section. The owner o r operator may seek an extension of this deadline for up to 30 additional days by submitting a written request to the Administrator before the expiration of the 45 day period. Until a request for an extension has been approved by the Administrator, the own er or operator is subject to the requirement to submit such report within 45 days of the initial occurrence of the exceedances. 60.

Section 60.2710 is revised to read as follows: §60.2710 How do I demonstrate continuous compliance with the amended emission limitations and the operating limits? (a) Compliance with standards. (1) The emission standards and operating requirements set forth in this subpart apply at all times. (2) If you cease combusting solid waste you may opt to remain subject to the provisions of this subpart. Consistent with the definition of CISWI unit, you are subject to the requirements of this subpart at least 6 months following the last date of solid waste combustion. S olid waste combustion is ceased when solid waste is not in the combustion chamber (i.e., the solid waste feed to the combustor has been cut off for a period of time not less than the solid waste residence time). (3) If you cease combusting solid waste you must be in compliance with any newly applicable standards on the effectivePage 301 of 382

date of the waste
- to - fuel switch. The effective date of the waste - to - fuel switch is a date selected by you, that must be at least 6 months from the date that you ceased combusting s olid waste, consistent with § 60.2710(a)(2). Your source must remain in compliance with this subpart until the effective date of the waste - to - fuel switch. (4) If you own or operate an existing commercial or industrial combustion unit that combusted a fuel o r non - waste material, and you commence or recommence combustion of solid waste, you are subject to the provisions of this subpart as of the first day you introduce or reintroduce solid waste to the combustion chamber, and this date constitutes the effective date of the fuel
- to - waste switch. You must complete all initial compliance demonstrations for any section 112 standards that are applicable to your facility before you commence or recommence combustion of solid waste. You must provide 30 days prior notic e of the effective date of the waste
- to - fuel switch. The notification must identify: (i) The name of the owner or operator of the CISWI unit, the location of the source, the emissions unit(s) that will cease burning solid waste, and the date of the notice; (ii) The currently applicable subcategory under this subpart, and any 40 CFR part 63 subpart and subcategory that will be applicable after you cease combusting solid waste;Page 302 of 382

(iii) The fuel(s), non
- waste material(s) and solid waste(s) the CISWI unit is curr ently combusting and has combusted over the past 6 months, and the fuel(s) or non
-waste materials the unit will commence combusting; (iv) The date on which you became subject to the currently applicable emission limits; (v) The date upon which you will cea se combusting solid waste, and the date (if different) that you intend for any new requirements to become applicable (i.e., the effective date of the waste
- to - fuel switch), consistent with (2) and (3)) above. (5) All air pollution control equipment necessa ry for compliance with any newly applicable emissions limits which apply as a result of the cessation or commencement or recommencement of combusting solid waste must be installed and operational as of the effective date of the waste
- to - fuel, or fuel
- to - wa ste switch. (6) All monitoring systems necessary for compliance with any newly applicable monitoring requirements which apply as a result of the cessation or commencement or recommencement of combusting solid waste must be installed and operational as of the effective date of the waste
- to - fuel, or fuel
- to -waste switch. All calibration and drift checks must be performed as of the effective date of the waste
- to - fuel, or fuel
- to -waste switch. Relative accuracy tests must be performed as of thePage 303 of 382

performance test deadline for PM CEMS. Relative accuracy testing for other CEMS need not be repeated if that testing was previously performed consistent with section 112 monitoring requirements or monitoring requirements under this subpart. (b) You must conduct an annual performance test for the pollutants listed in table 2 of this subpart or tables 6 through 9 of this subpart and opacity for each CISWI unit as required under §60.2690. The annual performance test must be conducted using the test methods listed in table 2 of this subpart or tables 6 through 9 of this subpart and the procedures in §60.2690. Opacity must be measured using EPA Reference Method 9 at 40 CFR part 60. Annual performance tests are not required if you use CEMS or continuous opacity monitoring systems to determine compliance. (c) You must continuously monitor the operating parameters specified in §60.2675 or established under §60.2680 and as specified in §60.2735.

* * * * * Performance evaluation means the conduct of relative accuracy testing, calibration error testing, and other measurements used in validating the continuous monitoring system data. Performance test means the collection of data resulting from the execution of a test method (usually three emission test runs) used to demonstrate compliance with a relevant emission standard as specified in the performance test section of the relevant standard. Process change means a significant permit revision, but only with respect to those pollutant
- specific emission units for which the proposed permit revision is applicab le, including but not limited to a change in the air pollution control devices used to comply with the emission limits for the affected CISWI unit (e.g., change in the sorbent used for activated carbon injection).Page 358 of 382

* * * * * Raw mill means a ball and tube mill, vertical roller mill or other size reduction equipment, that is not part of an in
line kiln/raw mill, used to grind feed to the appropriate size. Moisture may be added or removed from the feed during the grinding operation. If the raw mill is used to remove moisture from feed materials, it is also, by definition, a raw material dryer. The raw mill also includes the air separator associated with the raw mill.

* * * * * Small, remote incinerator means an incinerator that combusts solid waste (as that term is defined by the Administrator in 40 CFR part 241) and combusts 3 tons per day or less solid waste and is more than 25 miles driving distance to the nearest municipal solid waste landfill. Soil treatment unit means a unit that thermally treats petroleum

– contaminated soils for the sole purpose of site remediation. A soil treatment unit may be direct
- fired or indirect fired. A soil treatment unit is not an incinerator, waste -burning kiln, an energy recovery unit or a small, remote incinerator under this subpart. Solid waste incineration unit means a distinct operating unit of any facility which combusts any solid (as that term is defined by the Administrator in 40 CFR part 241) waste materialPage 359 of 382

from commercial or industrial establishments or the general public (including single and multiple residences, hotels and motels). Such term does not include incinerators or other units required to have a permit under section 3005 of the Solid Waste Disposal Act. The term "solid waste incineration unit" does not inc lude (A) materials recovery facilities (including primary or secondary smelters) which combust waste for the primary purpose of recovering metals, (B) qualifying small power production facilities, as defined in section 3(17)(C) of the Federal Power Act (16 U.S.C. 769(17)(C)), or qualifying cogeneration facilities, as defined in section 3(18)(B) of the Federal Power Act (16 U.S.C. 796(18)(B)), which burn homogeneous waste (such as units which burn tires or used oil, but not including refuse
derived fuel) for the production of electric energy or in the case of qualifying cogeneration facilities which burn homogeneous waste for the production of electric energy and steam or forms of useful energy (such as heat) which are used for industrial, commercial, heating or cooling purposes, or (C) air curtain incinerators provided that such incinerators only burn wood wastes, yard wastes and clean lumber and that such air curtain incinerators comply with opacity limitations to be established by the Administrator by rule. Space heater means a usually portable appliance for heating a relatively small area. A space heater is not an incinerator,Page 360 of 382

waste -burning kiln, an energy recovery unit or a small, remote incinerator under this subpart.

* * * * * Waste -burning kiln means a kiln that is heated, in whole or in part, by combusting solid waste (as that term is defined by the Administrator in 40 CFR part 241). A waste -burning kiln does not include a kiln that is feeding non
- hazardous secondary ingredients exclusively into the col d end of the kiln. Wet scrubber means an add
- on air pollution control device that uses an aqueous or alkaline scrubbing liquor to collect particulate matter (including nonvaporous metals and condensed organics) and/or to absorb and neutralize acid gases.

c. Revising the definition of “established tire collection programs.” **§241.2 Definitions.**

* * * * * Clean cellulosic bioma ss means those residuals that are akin to traditional cellulosic biomass, including, but not limited to: agricultural and forest
- derived biomass (e.g., green wood, forest thinnings, clean and unadulterated bark, sawdust, trim, tree harvesting residuals from logging and sawmill materials, hogged fuel, wood pellets, untreated wood pallets);Page 377 of 382

urban wood (e.g., tree trimmings, stumps, and related forest
derived biomass from urban settings ); corn stover and other biomass crops used specifically for the production of cellulosic biofuels (e.g., energy cane, other fast growing grasses, byproducts of ethanol natural fermentation processes); bagasse and other crop residues (e.g., peanut shells, vines, orchard trees, hulls, seeds, spent grains, cotton byproducts, corn and peanut production residues, rice milling and grain elevator operation residues); wood collected from forest fire clearance activities, trees and clean wood found in disaster debris, clean biomass from land clearing operations, and clean construction and demolition wood. These fuels are not secondary materials or solid wastes unless discarded. Clean biomass is biomass that does not contain contaminants at concentrations not normally associated with virgin biomass materials.

* * * * * Contaminants means al l pollutants listed in Clean Air Act sections 112(b) and 129(a)(4), with modifications outlined in this definition to reflect constituents found in non
- hazardous secondary materials prior to combustion. The definition includes the following elemental contaminants that commonly form Clean Air Act section 112(b) and 129(a)(4) pollutants: antimony, arsenic, beryllium, cadmium, chlorine, chromium, cobalt, fluorine, lead, manganese, mercury, nickel, nitrogen, selenium,Page 378 of 382

and sulfur. The definition does not include the following Clean Air Act section 112(b) and 129(a)(4) pollutants that are either unlikely to be found in non
- hazardous secondary materials prior to combustion or are adequately measured by other parts of this definition: hydrogen chloride (HCl), chlori ne gas (Cl 2 ), hydrogen fluoride (HF), nitrogen oxides (NO x ), sulfur dioxide (SO 2 ) , fine mineral fibers, particulate matter, coke oven emissions, diazomethane, white phosphorus, titanium tetrachloride, mcresol, o
- cresol, p
- cresol, m
- xylene, o
- xylene, and p
- xylene .
* * * * * Established tire collection program means a comprehensive collection system or contractual arrangement that ensures scrap tires are not discarded and are handled as valuable commodi ties through arrival at the combustion facility .
* * * * * **SUBPART B -**  **- Identification of Non**  **- Hazardous Secondary**  **Materials that are Solid Wastes When Used as Fuels or Ingredients in Combustion Units**  90. Amend 241.3 as follows:
a. Revise paragraph (a) , b. Revise paragraphs (b)(2) (i) and (b)(2) (i i ),
c. Revise paragraph (d)(1)(iii).Page 379 of 382

§241.3 Standards and Procedures for Identification of Non
Hazardous Secondary Materials that are Solid Wastes When Used as Fuels or Ingredients in Combustion Units. (a) Except as provided in paragraph (b) of this section or in 241.4(a) of this subpart, non
- hazardous secondary materials that are combusted are presumed to be solid wastes, unless a petition is submitted to, and a determination granted by, the Regional Administrator pursuant to paragraph (c) of this section. The criteria to be addressed in the petition, as well as the process for making the non
-waste determination, are specified in paragraph (c) of this section. (b) * * * (2) * * * (i) [Reserved] (i i ) [Reserved]

* * * * * (d) * * * (1) * * * (iii) The non
- hazardous secondary material must contain contaminants or groups of contaminants at levels comparable in concentration to or lower than those in traditional fuel(s) which the combustion unit is designed to burn. In determining which traditional fuel(s) a unit is designed to burn, persons can choose a traditional fuel that can be or is burned in thePage 380 of 382

particular type of boiler, whether or not the combustion unit is permitted to burn that traditiona l fuel. In comparing contaminants between traditional fuel(s) and a non
- hazardous secondary material, persons can use ranges of traditional fuel contaminant levels compiled from national surveys, as well as contaminant level data from the specific traditio nal fuel being replaced. Such comparisons are to be based on a direct comparison of the contaminant levels in both the non
- hazardous secondary material and traditional fuel(s) prior to combustion.

* * * * * 91. Add § 241.4 to read as follows: §241.4 Non
-Wa ste Determinations for Specific Non
- Hazardous Secondary Materials When Used as a Fuel. (a) The following non
- hazardous secondary materials are not solid wastes when used as a fuel in a combustion unit: (1) Scrap tires that are not discarded and are managed under the oversight of established tire collection programs, including tires removed from vehicles and off
- specification tires. (2) Resinated wood. (b) Any person may submit a rulemaking petition to the Administrator to identify additional non
- hazardous secondary materials to be listed in paragraph (a) of this section.Page 381 of 382

Contents and procedures for submittal of the petitions include the following: (1) Each petition must be submitted to the Administrator by certified mail and must include: (i) The petitione r's name and address; (ii) A statement of the petitioner's interest in the proposed action; (iii) A description of the proposed action, including (where appropriate) suggested regulatory language; and (iv) A statement of the need and justification for the proposed action, including any supporting tests, studies, or other information. Where the non
- hazardous secondary material does not meet the legitimacy criteria, the applicant must explain why such non
- hazardous secondary material should be considered a no n - waste fuel, balancing the legitimacy criteria with other relevant factors. (2) The Administrator will make a tentative decision to grant or deny a petition and will publish notice of such tentative decision, either in the form of an advanced notice of proposed rulemaking, a proposed rule, or a tentative determination to deny the petition, in the Federal Register for written public comment. (3) Upon the written request of any interested person, the Administrator may, at its discretion, hold an informal publicPage 382 of 382

hearing to consider oral comments on the tentative decision. A person requesting a hearing must state the issues to be raised and explain why written comments would not suffice to communicate the person's views. The Administrator may in any case deci de on its own motion to hold an informal public hearing. (4) After evaluating all public comments the Administrator will make a final decision by publishing in the Federal Register a regulatory amendment or a denial of the petition. (5) The Administrator w ill grant or deny a petition based on the weight of evidence showing the following: (i) The non
- hazardous secondary material has not been discarded in the first instance and is legitimately used as a fuel in a combustion unit, or if discarded, has been suf ficiently processed into a material that is legitimately used as a fuel. (ii) Where any one of the legitimacy criteria in section 241.3(d)(1) is not met, that the use of the non
- hazardous secondary material is integrally tied to the industrial production process, that the non
- hazardous secondary material is functionally the same as the comparable traditional fuel, or other relevant factors as appropriate.
