A. Site-Specific Alternative Standard
II. Amendments to Subpart MM
https://www.federalregister.gov/d/03-3702 https://www.federalregister.gov/d/03-3702
The EPA is taking direct final action on amendments to the national emission standards for hazardous air pollutants (NESHAP) for chemical recovery combustion sources at kraft, soda, sulfite, and stand-alone semichemical pulp mills, which were issued on January 12, 2001 under section 112 of the Clean Air Act (CAA). The amendments clarify and consolidate the monitoring and testing requirements and add a site-specific alternative standard for one pulp mill. We are issuing these amendments as a direct final rule, without prior proposal, because we view the revisions as noncontroversial and anticipate no significant adverse comments. However, in the Proposed Rules section of this Federal Register, we are publishing a separate document that will serve as the proposal to amend the national emission standards for chemical recovery combustion sources at kraft, soda, sulfite, and stand-alone semichemical pulp mills if significant adverse comments are filed.

This table is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be regulated by this action. To determine whether your facility is regulated by this action, you should carefully examine the applicability criteria in § 63.860 of the national emission standards. If you have questions regarding the applicability of this action to a particular entity, consult the person listed in the preceding FOR FURTHER INFORMATION CONTACT section of this document.
Docket. The EPA has established an official public docket for this action under Docket ID No. OAR-2002-0045. The official public docket is the collection of materials that is available for public viewing at the EPA Docket Center (Air Docket), EPA West, Room B-108, 1301 Constitution Avenue, NW, Washington, DC 2004. The Docket Center is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal holidays. The telephone number for the Reading Room is (202) 566-1744, and the telephone number for the Air Docket is (202) 566-1742.
Direct Final Rule. We are publishing the direct final rule without prior proposal because we view the amendments as noncontroversial and do not anticipate significant adverse comments. We anticipate no significant adverse comments because EPA received no adverse comments when we published similar amendments during 2001. Furthermore, with respect to the amendment regarding an individual sulfite pulp mill located in Cosmopolis, Washington, EPA has already received favorable comments on the amendment from the State of Washington. The EPA received one adverse comment during the CAA section 113(g) comment period on the draft settlement agreement between EPA and Weyerhaeuser Paper Company, which described the amendment at issue, which comment is being addressed directly in this notice (although this response does not bar further comment). However, in the Proposed Rules section of this Federal Register, we are publishing a separate document that will serve as the proposal to amend the national emission standards for chemical recovery combustion sources at kraft, soda, sulfite, and stand-alone semichemical pulp mills if significant adverse comments are filed.
If we receive any significant adverse comments on one or more distinct amendments, we will publish a timely withdrawal in the Federal Register informing the public which provisions will become effective and which provisions are being withdrawn due to adverse comment. We will address all public comments in a subsequent final rule, should the Agency determine to issue one. Any of the distinct amendments in today's rule for which we do not receive significant adverse comment will become effective on the date set out above. We will not institute a second comment period on the direct final rule. Any parties interested in commenting must do so at this time.
Worldwide Web (WWW). In addition to being available in the docket, an electronic copy of today's document will also be available on the WWW through EPA's Technology Transfer Network (TTN). Following the Administrator's signature, a copy of this action will be posted on the TTN's policy and guidance page for newly proposed or promulgated rules at http://www.epa.gov/​ttn/​oarpg. The TTN provides information and technology exchange in various areas of air pollution control. If more information regarding the TTN is needed, call the TTN HELP line at (919) 541-5384.
Judicial Review. Under section 307(b)(1) of the CAA, judicial review of the direct final rule is available only by filing a petition for review in the U.S. Court of Appeals for the District of Columbia Circuit by April 21, 2003. Under section 307(d)(7)(B) of the CAA, only an objection to the direct final rule which was raised with reasonable specificity during the period for public comment can be raised during judicial review. Moreover, under section 307(b)(2) of the CAA, the requirements established by the direct final rule may not be challenged separately in any civil or criminal proceedings brought by EPA to enforce these requirements.
C. Regulatory Flexibility Act (RFA) as Amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. et seq.
The EPA promulgated national emission standards for hazardous air pollutants for chemical recovery combustion sources at kraft, soda, sulfite, and stand-alone semichemical pulp mills on January 12, 2001 (66 FR 3180). The final rule (40 CFR part 63, subpart MM) includes standards for hazardous air pollutants (HAP), as well as monitoring, performance testing, recordkeeping, and reporting requirements. The EPA established a site-specific potential compliance date under subpart MM for Georgia-Pacific Corporation's stand-alone semichemical pulp mill in Big Island, Virginia (66 FR 16400, March 26, 2001). The EPA published technical corrections to subpart MM on July 19, 2001 (66 FR 37591), which corrected the compliance date and oxygen correction equations and clarified the performance testing requirements to account for all applicable test methods and sources. Today's action includes amendments to clarify and consolidate the monitoring and testing requirements and adds a site-specific alternative standard for HAP metals for Weyerhaeuser Paper Company's sulfite pulp mill in Cosmopolis, Washington. Start Printed Page 7708
The NESHAP for chemical recovery combustion sources at kraft, soda, sulfite, and stand-alone semichemical pulp mills includes a HAP metals standard for existing sulfite combustion units, using particulate matter (PM) emissions as a surrogate for HAP metals emissions. The final rule requires existing sulfite combustion units to reduce HAP metals emissions, measured as PM, to a level less than or equal to 0.040 grains per dry standard cubic foot (gr/dscf), corrected to 8 percent oxygen (§ 63.862(a)(2)).
Following promulgation of the rule, Weyerhaeuser Paper Company requested that EPA issue a site-specific alternative standard under subpart MM for Weyerhaeuser's Cosmopolis, Washington sulfite pulp mill. The alternative standard would allow Weyerhaeuser to reduce HAP metals emissions from an onsite emission source called a hog fuel dryer in lieu of complying with the HAP metals standard for existing sulfite combustion units. The hog fuel dryer at the Cosmopolis mill is used to dry solid fuel, such as bark, prior to combustion of the fuel in an onsite boiler. The hog fuel dryer is not regulated under a NESHAP and appears to be unique. Compliance with the alternative standard will result in greater annual HAP metals emissions reductions, lower annual energy utilization, and lower compliance costs at the Cosmopolis mill than would have been achieved through compliance with the HAP metals standard for sulfite combustion units.
Weyerhaeuser's Cosmopolis, Washington mill is a magnesium-based sulfite mill with three chemical recovery furnaces. These three recovery furnaces are subject to the HAP metals standard in subpart MM for existing sulfite combustion units. The emissions from each recovery furnace are first routed through a multiclone to recover magnesium oxide (particulate) and then through a cooling tower followed by absorption towers to recover sulfur dioxide. Following the absorption towers, the emissions from the three recovery furnaces are combined and treated in an educted venturi scrubber before being emitted to the atmosphere through a common stack.
The recovery furnaces are subject to a Washington State permit PM limit of 0.1 gr/dscf. The applicable NESHAP limit of 0.040 gr/dscf, corrected to 8 percent oxygen, is more stringent and would supersede the State limit. The hog fuel dryer is also subject to a State permit PM limit of 0.1 gr/dscf. However, the hog fuel dryer is not subject to any NESHAP. The hog fuel dryer is equipped with cyclones to reduce PM emissions. The alternative standard probably cannot be achieved without installation of a fabric filter, and Weyerhaeuser intends to replace the existing cyclones on the hog fuel dryer with a fabric filter after promulgation of the site-specific alternative standard.
Environmentally beneficial practices at the Cosmopolis mill include the use of oxygen delignification and elemental chlorine-free and oxygen bleaching. The load on the recovery furnaces has increased as a result of oxygen delignification and a decision by the mill to burn sludge from onsite wastewater treatment in the recovery furnaces. Although the mill recovers energy from burning the biosolids, this practice has resulted in an increase in PM emissions from the recovery furnaces. However, the mill is still able to consistently meet its State permit PM limit.
The sulfite recovery furnaces at the Cosmopolis mill are tested monthly for PM. Based on the monthly data collected during the past 12 years, the mill cannot consistently meet EPA's NESHAP standard for HAP metals from existing sulfite recovery furnaces (0.040 gr/dscf at 8 percent oxygen, measured as PM) without a significant investment in a new emission control device. Because the exhaust gas volume from the hog fuel dryer is much smaller than the exhaust gas volume from the recovery furnaces, Weyerhaeuser determined that it would be much less costly for the Cosmopolis mill to install more efficient controls to reduce HAP metals emissions from the hog fuel dryer than from the recovery furnaces. Weyerhaeuser estimates that the capital cost of controlling the emissions from the recovery furnaces would be approximately $4 million (based on installation of a wet electrostatic precipitator) versus approximately $1.3 million to control emissions from the hog fuel dryer (based on installation of a fabric filter). The operating cost of the fabric filter for control of hog fuel dryer emissions would be about the same as the operating costs of the existing mechanical cyclone, which the fabric filter would replace. Weyerhaeuser also estimates that the operating costs of the wet electrostatic precipitator for control of recovery furnace emissions would be approximately $60,000 per year.
Weyerhaeuser conducted HAP emission tests to determine and compare the quantity of HAP metals emitted from the recovery furnaces (combined stack) versus the hog fuel dryer under current operating conditions. The recovery furnaces and hog fuel dryer were tested for the following 11 HAP metals: antimony, arsenic, beryllium, cadmium, chromium, cobalt, mercury, manganese, nickel, lead, and selenium. Based on the results of the emission tests, the sulfite recovery furnaces collectively emit approximately 212 pounds per year (lb/yr) of HAP metals, and the hog fuel dryer emits approximately 441 lb/yr. (See Docket ID No. OAR-2002-0045.) Both the recovery furnaces and hog fuel dryer emit very similar types of HAP metals. For both emission sources, the top four HAP metals emitted were manganese, lead, chromium, and nickel, accounting for 98.5 percent of the recovery furnace HAP metals emissions and 98.9 percent of the hog fuel dryer HAP metals emissions. Manganese was the predominant HAP metal emitted from both sources. The recovery furnaces emitted 0.025 pounds per hour (lb/hr) of manganese, accounting for 86 percent of the recovery furnace HAP metals emissions. The hog fuel dryer emitted 0.10 lb/hr of manganese, accounting for 97 percent of the hog fuel dryer HAP metals emissions. (See Docket ID No. OAR-2002-0045.) None of these metals are added to the mill's manufacturing process but are naturally occurring metals present in the wood chips and hog fuel processed at the mill.
Compliance with EPA's HAP metals standard for existing sulfite combustion units would reduce HAP metals emissions from the recovery furnaces by about 30 percent using PM as a surrogate for HAP metals. Assuming the same emissions reductions are achieved for HAP metals as for PM, compliance with the HAP metals standard for existing sulfite combustion units would reduce HAP metals emissions from the recovery furnaces by approximately 64 lb/yr. As an alternative to controlling HAP metals emissions from the recovery furnace, Weyerhaeuser proposes that the hog fuel dryer at their Cosmopolis, Washington mill meet a PM emission limit of 10.0 lb/hr (with PM serving as a surrogate for HAP metals emissions), which is equivalent to a PM emissions concentration of 0.030 gr/dscf. The hog fuel dryer's current PM emissions concentration is 0.081 gr/dscf. Weyerhaeuser's proposed PM emission limit for the hog fuel dryer would require that the mill reduce PM emissions from the hog fuel dryer by approximately 63 percent. Assuming the same emissions reductions are achieved for HAP metals as for PM, the total HAP metals emission reduction for the alternative standard would be approximately 278 lb/yr, which is more than four times the HAP metals Start Printed Page 7709emissions reductions that would be achieved through compliance with the HAP metals standard for existing sulfite combustion units.
After reviewing the test reports and other documentation provided by Weyerhaeuser, we agree with Weyerhaeuser's request to include an alternative standard in subpart MM because the alternative achieves greater emissions reductions of the same HAP metals and does so by controlling a source otherwise unregulated under subpart MM or any other NESHAP. The emission test reports and other documents related to the alternative standard are provided in the project docket. (See Docket ID No. OAR-2002-0045.)
The EPA received one adverse comment on the proposed settlement agreement. The commenter maintained that once EPA learned that there was an unregulated emission point at the Cosmopolis mill, the Agency had no choice but to develop a maximum achievable control technology (MACT) standard for that emission point in addition to the MACT standard for all other emission points. The commenter further suggested that the unregulated emission point would be subject to case-by-case MACT (under section 112(j) of the Act).
The EPA appreciates this thoughtful comment, but does not agree with it. First, although the commenter's approach is permissible, it is not compelled. The EPA typically develops MACT standards for a series of aggregated plant operations, not for individual emission points, in keeping with the requirement in section 112(d)(2) to develop emission standards applicable to new or existing “sources”. A “source” can include an entire facility. See sections 112(a)(3) and 111(a)(3). In this case, EPA has determined that MACT for the aggregated unit operations involved in black liquor recovery (the source category subject to this rule) is a given amount of HAP emissions. Indeed, the standard for HAP metals in the existing rule (the HAP also emitted by the hog fuel dryer) is expressed as an aggregated limit (along with an alternative standard expressing the standard on an emission point by emission point basis). See section 63.862(a)(1)(ii)(A). In this rule, EPA is providing an alternative means of complying with that MACT limit (a means which, as explained above, results in more HAP reduction than otherwise provided for in the rule). The EPA notes further that it has pursued this same approach to compliance in a number of Project XL applications. See, e.g. 66 FR 34119, 34120 (June 27, 2001) (final rule) and 66 FR 16637, 16640 (March 27, 2001) (proposed rule).
The commenter's further point regarding use of 112(j) to develop case-by-case MACT for the single emission point also is not compelled (and probably is not permissible). Once EPA promulgates a valid MACT standard for a source category, the Agency has fulfilled its statutory obligation and no case-by-case limitation may issue.
Finally, even if one were to accept the commenter's argument that MACT must be developed on an emission point by emission point basis, a standard for a hog fuel dryer would likely be some type of beyond-the-floor, given the absence of this emission point at other facilities and absence of controls at the one facility operating this type of unit. The EPA thus would be compelled to consider the cost, non-air quality environmental and health impacts and energy requirements of a standard (as required by section 112(d)(2)), and would not be obligated to promulgate a standard based upon consideration of those factors. Thus, even under the commenter's approach, it would not follow that a standard would result.
The NESHAP for chemical recovery combustion sources at kraft, soda, sulfite, and stand-alone semichemical pulp mills includes standards, as well as monitoring, performance testing, recordkeeping, and reporting requirements. Technical corrections to subpart MM were published by EPA on July 19, 2001, correcting the compliance date and oxygen concentration equations and clarifying the performance testing requirements to account for all applicable test methods and sources. After these technical corrections were published, it became evident that additional technical corrections were needed to provide further clarification of the monitoring and testing requirements. Today's action includes those technical corrections, which are described previously in this preamble.
Today's action includes amendments to clarify and consolidate the monitoring and testing requirements and adds a site-specific alternative standard for Weyerhaeuser Paper Company's sulfite pulp mill in Cosmopolis, Washington.
As described above, the alternative standard will allow the mill to reduce emissions from an onsite hog fuel dryer in lieu of complying with the standard for HAP metals for existing sulfite combustion units specified in § 63.862(a)(2). The alternative standard will limit HAP metals emissions from the hog fuel dryer by limiting PM emissions to a level less than or equal to 10.0 lb/hr. Weyerhaeuser will install a fabric filter on the hog fuel dryer to achieve compliance with the alternative standard and must continuously monitor the performance of the fabric filter using a bag leak detection system with an audible alarm system. Weyerhaeuser must perform an initial compliance test using the test methods specified in the NESHAP to demonstrate that the PM emissions from the hog fuel dryer meet the alternative standard. Weyerhaeuser also must develop and implement a written startup, shutdown, and malfunction plan that contains specific procedures to be followed for operating and maintaining the hog fuel dryer and fabric filter during periods of startup, shutdown, and malfunction, and a program of corrective action if the hog fuel dryer or fabric filter malfunctions. Weyerhaeuser must take corrective action as specified in its startup, shutdown, and malfunction plan whenever the bag leak detection alarm sounds. The Cosmopolis mill will be in violation of the alternative standard if corrective action is not initiated within 1 hour of a bag leak detection alarm, corrective action is not completed in accordance with the startup, shutdown, and malfunction plan, or the alarm is engaged for more than 5 percent of the total operating time during a 6-month block reporting period.
The EPA is granting Weyerhaeuser's request for an alternative standard for its Cosmopolis, Washington sulfite mill because compliance with the alternative standard will result in a greater reduction in HAP metals emissions than would be achieved through compliance with the HAP metals standard for existing sulfite combustion units, and at a lower cost to the mill. The HAP metals emissions reductions will be at least four times greater under the alternative standard, and energy utilization will be lower.
The changes to subpart MM resulting from inclusion of amendments to clarify the monitoring and testing requirements and addition of a site-specific alternative standard for Weyerhaeuser's Cosmopolis, Washington mill are described in Table 1 of this preamble. Start Printed Page 7710

§ 63.867(a)(3) Add a notification of compliance status requirement for the bag leak detection system for the hog fuel dryer at Weyerhaeuser Paper Company's Cosmopolis, Washington mill.
Under Executive Order 12866 (58 FR 5173, October 4, 1993), EPA must determine whether the regulatory action is “significant” and, therefore, subject to Office of Management and Budget (OMB) review and the requirements of the Executive Order. The Executive Order defines “significant regulatory action” as one that is likely to result in standards that may:
The information collection requirements in the final rule were submitted to and approved by OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and assigned OMB control number 2060-0377. An Information Collection Request (ICR) document was prepared by EPA (ICR No. 1805.03) and a copy may be obtained from Susan Auby by mail at Office of Environmental Information, Collection Strategies Division (MD-2822T), 1200 Pennsylvania Avenue, NW, Washington DC 20460, by e-mail at auby.susan@epa.gov, or by calling (202) 566-1672. A copy may also be downloaded from the internet at http://www.epa.gov/​icr.
Today's action makes clarifying changes to the final rule and imposes no new information collection requirements on the industry. Because there is no additional burden on the industry as a result of this direct final rule, the ICR has not been revised.
For purposes of assessing the impacts of today's final rule on small entities, small entity is defined as: (1) A small business that has fewer than 750 employees for NAICS codes 32211, 32212, and 32213 (pulp, paper, and paperboard mills); (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.
After considering the economic impacts of today's final rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. In determining whether a rule has a significant economic impact on a substantial number of small entities, the impact of concern is any significant adverse economic impact on small entities, since the primary purpose of the regulatory flexibility analyses is to identify and address regulatory alternatives which minimize any significant economic impact of the proposed rule on small entities (5 U.S.C. 603-604). Thus, an agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, or otherwise has a positive effect on the small entities subject to the rule. The amendments in today's rule make improvements to the emission standards, primarily by clarifying issues in the areas of testing and monitoring and add a new compliance option. We have, therefore, concluded that today's final rule will have no adverse impacts on any small entities and may relieve burden in some cases. Start Printed Page 7712
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of the UMRA, the EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with “Federal mandates” that may result in expenditures to State, local, and tribal governments, in the aggregate, or to the private sector, of $100 million or more in any 1 year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires the EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective, or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows the EPA to adopt an alternative other than the least costly, most cost-effective, or least burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before the EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, it must have developed under section 203 of the UMRA a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements.
The EPA has determined that the direct final rule does not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in aggregate, or the private sector in any 1 year, nor does the direct final rule significantly or uniquely impact small governments, because it contains no requirements that apply to such governments or impose obligations upon them. Thus, the requirements of the UMRA do not apply to the direct final rule.
Executive Order 13175 (65 FR 67249, November 6, 2000) requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” The final rule does not have tribal implications, as specified in Executive Order 13175, because tribal governments do not own or operate any sources subject to the amendments. Thus, Executive Order 13175 does not apply to the direct final rule.
The EPA interprets Executive Order 13045 as applying only to regulatory actions that are based on health or safety risks, such that the analysis required under section 5-501 of the Executive Order has the potential to influence the regulation. The direct final rule is not subject to Executive Order 13045, because it is based on technology performance and not on health or safety risks.
Section 12(d) of the NTTAA (Pub. L. 104-113; 15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory and procurement activities, unless to do so would be inconsistent with applicable law or otherwise impractical. One voluntary consensus standard, ANSI/ASME PTC 19.10-1981—Part 10 (“Flue and Exhaust Gas Analysis”), has been identified as an acceptable alternative to EPA Method 3B for the purposes of this action. The voluntary consensus standard ANSI/ASME PTC 19.10-1981—Part 10 is cited in today's action for its manual method for measuring the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas. This part of ANSI/ASME PTC 19.10-1981—Part 10 is an acceptable alternative to EPA Method 3B. The EPA is not proposing/adopting any other voluntary consensus standards in this action.
The Congressional Review Act (5 U.S.C. 801 et seq.), as added by SBREFA of 1996, generally provides that, before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. The EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. The direct final rule is not a “major rule” as defined by 5 U.S.C. 804(2). The direct final rule will become effective on May 19, 2003, unless significant adverse comments are received by March 20, 2003.

In calculating the operating time fraction, if inspection of the fabric filter demonstrates that no corrective action is required, no alarm time is counted; if corrective action is required, each alarm is counted as a minimum of 1 hour; if corrective action is not initiated within 1 hour, the alarm time is counted as the actual amount of time taken to initiate corrective action.
(vi) For an affected source or process unit equipped with an ESP, wet scrubber, RTO, or fabric filter and monitoring alternative operating parameters established in paragraph (e)(13) of this section, when six or more 3-hour average values within any 6-month reporting period are outside the range of parameter values established in paragraph (j) of this section; and
(vii) For an affected source or process unit equipped with an alternative air pollution control system and monitoring operating parameters approved by the Administrator as established in paragraph (e)(14) of this section, when six or more 3-hour average values within any 6-month reporting period are outside the range of parameter values established in paragraph (j) of this section.

HD-14), Method 5 or 29 in appendix A of 40 CFR part 60 must be used, except that Method 17 in appendix A of 40 CFR part 60 may be used in lieu of Method 5 or Method 29 if a constant value of 0.009 g/dscm (0.004 gr/dscf) is added to the results of Method 17, and the stack temperature is no greater than 205 °C (400 °F). For Methods 5, 29, and 17, the sampling time and sample volume for each run must be at least 60 minutes and 0.90 dscm (31.8 dscf), and water must be used as the cleanup solvent instead of acetone in the sample recovery procedure.
(2) For sources complying with § 63.862(a) or (b), the PM concentration must be corrected to the appropriate oxygen concentration using Equation 7 of this section as follows:
Ccorr = The measured concentration corrected for oxygen, g/dscm (gr/dscf);

(ii) For purposes of determining stack gas velocity and volumetric flow rate, Method 2, 2A, 2C, 2D, 2F, or 2G in appendix A of 40 CFR part 60 must be used;
(iii) For purposes of conducting gas analysis, Method 3, 3A, or 3B in appendix A of 40 CFR part 60 must be used. The voluntary consensus standard ANSI/ASME PTC 19.10-1981—Part 10 (incorporated by reference—see § 63.14) may be used as an alternative to using Method 3B; and
(iv) For purposes of determining moisture content of stack gas, Method 4 in appendix A of 40 CFR part 60 must be used.
(c) The owner or operator of each affected source or process unit complying with the gaseous organic HAP standard in § 63.862(c)(1) must demonstrate compliance according to the provisions in paragraphs (c)(1) and (2) of this section.
(1) The owner or operator complying through the use of an NDCE recovery furnace equipped with a dry ESP system is not required to conduct any performance testing to demonstrate compliance with the gaseous organic HAP standard.
(2) The owner or operator complying without using an NDCE recovery furnace equipped with a dry ESP system must use Method 308 in appendix A of this part, as well as the methods listed in paragraphs (b)(5)(i) through (iv) of this section. The sampling time and sample volume for each Method 308 run must be at least 60 minutes and 0.014 dscm (0.50 dscf), respectively.
(i) The emission rate from any new NDCE recovery furnace must be determined using Equation 9 of this section as follows:
ERNDCE = Methanol emission rate from the NDCE recovery furnace, kg/Mg (lb/ton) of black liquor solids fired;
MRmeas = Measured methanol mass emission rate from the NDCE recovery furnace, kg/hr (lb/hr); and
BLS = Average black liquor solids firing rate of the NDCE recovery furnace, megagrams per hour (Mg/hr) (tons per hour (ton/hr)) determined using process data measured during the performance test.
(ii) The emission rate from any new DCE recovery furnace system must be determined using Equation 10 of this section as follows:
ERDCE = Methanol emission rate from each DCE recovery furnace system, kg/Mg (lb/ton) of black liquor solids fired;
MRmeas,RF = Average measured methanol mass emission rate from each DCE recovery furnace, kg/hr (lb/hr);
MRmeas,BLO = Average measured methanol mass emission rate from the black liquor oxidation system, kg/hr (lb/hr);
BLSRF = Average black liquor solids firing rate for each DCE recovery furnace, Mg/hr (ton/hr) determined using process data measured during the performance test; and
BLSBLO = The average mass rate of black liquor solids treated in the black liquor oxidation system, Mg/hr (ton/hr) determined using process data measured during the performance test.

(d) The owner or operator seeking to determine compliance with the gaseous organic HAP standards in § 63.862(c)(2) for semichemical combustion units must use Method 25A in appendix A of 40 CFR part 60, as well as the methods listed in paragraphs (b)(5)(i) through (iv) of this section. The sampling time for each Method 25A run must be at least 60 minutes. The calibration gas for each Method 25A run must be propane.
(1) The emission rate from any new or existing semichemical combustion unit must be determined using Equation 11 of this section as follows:
ERSCCU = THC emission rate reported as carbon from each semichemical combustion unit, kg/Mg (lb/ton) of black liquor solids fired;
THCmeas = Measured THC mass emission rate reported as carbon, kg/hr (lb/hr); and
BLS = Average black liquor solids firing rate, Mg/hr (ton/hr); determined using process data measured during the performance test.
8. Section 63.866 is amended by:
d. Adding paragraph (c)(7).
(c) In addition to the general records required by § 63.10(b)(2), the owner or operator must maintain records of the information in paragraphs (c)(1) through (7) of this section:
(1) Records of black liquor solids firing rates in units of Mg/d or ton/d for all recovery furnaces and semichemical combustion units;
(2) Records of CaO production rates in units of Mg/d or ton/d for all lime kilns;
(7) For the bag leak detection system on the hog fuel dryer fabric filter at Weyerhaeuser Paper Company's Cosmopolis, Washington facility (Emission Unit no. HD-14), records of each alarm, the time of the alarm, the time corrective action was initiated and completed, and a brief description of the cause of the alarm and the corrective action taken.
9. Section 63.867 is amended by adding paragraph (a)(3) to read as follows:
(3) In addition to the requirements in subpart A of this part, the owner or operator of the hog fuel dryer at Weyerhaeuser Paper Company's Cosmopolis, Washington facility (Emission Unit no. HD-14) must include analysis and supporting documentation demonstrating conformance with EPA guidance and specifications for bag leak detection systems in § 63.864(a)(7) in the Notification of Compliance Status.
