I. Introduction

S ection 111 (b)(1)(B) of the Clean Air Act ( CAA ) mandates that the EPA review and, if appropriate, revise the existing new sour ce performance standards (NSPS) at least every 8 years. The kraft pulp mills NSPS (40 CFR part 60, subpart BB) were promulgated in 197 8 and reviewed in 1986. The NSPS regulate emissions of particulate matter (PM) from new, modified,

and reconstructed recov ery furnaces, smelt dissolving tanks (SDTs) , and lime kilns at kraft pulp mills. The NSPS also regulate emissions of total reduce sulfur (TRS) compounds from new, modified, and reconstructed digesters, brown stock washers, multiple

- effect evaporators,

cond ensate strippers, recovery furnaces, SDTs , and lime kilns at kraft pulp mills. On December 6, 2011, the Center for Biological Diversity, Greenpeace, and the Port Townsend Airwatchers filed a complaint (Clean Air Act citizen suit) against the EPA to review the NSPS for kraft pulp

mills . The EPA has entered into a consent decree with the petitioners, specifying proposal of the NSPS review by May 15, 2013 and promulgation by March 14, 2014. See docket number EPA

The purpose of this memorandum is to present the results of a review of the air permits for existing kraft pulp mills. These permits were obtained through state regulatory agencies as well

as p rovided by the pulp and paper industry in response to a 20 1 1 Information Collection Request (ICR) survey

. This analysis is part of the EPA ’s effort to review the NSPS for kraft pulp mills in accordance with section 111(b)(1)(B) of the CAA.

I I

. General Approach to Tabulating and Reviewing Air Permits

Permits a nd permit limits were collected from the pulp and paper industry in 2011 in response

to a CAA section 114 ICR. The three

- part survey was distributed by the EPA in February 2011 and requested 2 0 0 9 b a s e y e a r information needed to perform various regulatory reviews,

includin g the review of the subpart BB NSPS. The ICR requested that permit limits for each emission unit be provided by populating the survey spreadsheet

, or by providing a copy of the air operating permit

. Permits that were not provided in response to the ICR wer e collected via state contacts and state websites. A list of state websites is provided in Table A

- 1 of Appendix A.2 

### The general approach for processing the permit data was to extract the data from the ICR responses and the permits into “ tabulation spreads heets. ” Separate tabulation spreadsheets were developed for each source (recovery furnace, SDT, and lime kiln ) to include emission limits for each pollutant (opacity, PM, and TRS)

. Emission limits for TRS were also extracted for non

condens a ble gas ( NCG ) sources (digesters, evaporators, and brown stock washers), as well as for condensate stripper systems. Facilities were identified by RTI facility code and emission units were identified by emission unit ID. A combined facility and emission unit ID was assi gned to each permit limit, with the format of RTI facility code followed by emission unit ID with a period as a separator for the two values ( e.g., 100.037A)

. After tabulation, a representative emission limit was determined for each pollutant and each emis sion unit. Incinerat o r operating and monitoring parameters were also collected from permits, as appropriate.

Permit limits extracted from the survey spreadsheets and the state permit ting website s were converted to consistent units for comparison to the c urrent NSPS emission limits. State

- based mass limits were not requested to be reported in the spreadsheets and were not extracted from the permits unless the mass

- based limit was the only limit reported for a pollutant. If a facility provided responses to the permit spreadsheet tab in the ICR, and the limit in the permit was higher than that specified in the ICR by the facility, the ICR limit was used as the representative limit, not what was written in the permit provided. In some cases, facilities identif ied that a limit was equivalent to a standard, but provided limits that were not equivalent. The representative

limit for these units was assumed to be the limit in the standard that the facility identified as equivalent. A few facilities provided new limi ts in their ICR responses that were pending permit approval and were lower than the limits in the permit provided. The pending limits were used as the representative limit.

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for pulp and paper combustion sources ( 40 CFR part 63, s ubpart MM) establishes PM limits (as a surrogate for metal HAPs) for each affected source or emission unit ( i.e. , recovery furnaces, SDTs , and lime kilns). The NESHAP a lso provides an alternative approach for com pliance , referred to as the PM bubble compliance alternative (§63.862(a)(ii)), which allows facilities to establish limits for the individual process units (recovery furnaces, SDTs, and lime kilns), as long as the combined limit for these units is no highe r than the sum of the promulgated limits for the units

. Information regarding the participation of facilities in the PM bubble compliance alternative was also collected, as participating units may have permitted limits lower than the standard if emissions

were used as a credit, or higher than the standard if emissions were used as a debit

.

The NESHAP for pulping and papermaking ( 40 CFR part 63, subpart S) establishes a HAP reduction limit for digesters, evaporators, brown stock washers, and condensate str ippers. If the permits did not reference the NSPS TRS requirements for these sources, but did reference incineration requirements from subpart S, incineration was noted in the tabulation spreadsheets as the method used to treat TRS. The NESHAP also provide s an alternative approach for compliance, referred to as the clean condensate alternative (CCA). The CCA allows mills to meet the HVLC emission requirements by reducing the HAP emissions elsewhere, usually process water. This approach allows mills to contr ol HAP emissions by reducing the amount of HAPs that are volatilized from selected process equipment instead of using combustion devices3 

### to control HVLC system vent streams. In a classic example, HAP condensates in paper machine process water are removed. By reducing the HAP concentration in process water, the amounts of volatilized HAPs are also reduced. For more information on CCA, see the memo titled Summary of Clean Condensate Alternative Technology Review in docket number EPA

The fo llowing sections discuss specific steps used to analyze the permit data for the separate

standards.

A. Permit Review: Opacity

Opacity limits were tabulated from the ICR responses and the state permitting websites and

were analyzed . In many cases, multip le opacity limits were listed for a source. These limits were

combined in the tabulation spreadsheet as the representative limit for the unit. For example, a recovery furnace with two separate opacity limits ( in two separate columns of the spreadsheet )

suc h as the following: permit limit 1 ) 25 percent (1

- hour average)

, and permit limit 2 ) 35 percent (6

- min average)

, were combined into one column as the representative limit 25 percent (1

- hour average) and 35 percent (6

- min average). When multiple limits with the same averaging time

were listed for an emission unit, the representative limit was assumed to be the most stringent of the limits. For example, if a recovery furnace had two separate opacity limits (in two separate

columns of the spreadsheet ) listed a s 40 percent (6

- min average) and 35 percent (6

- min average),

it was assumed that the limit that the unit must meet at all times is 35 percent (6

- min average). Representative limits were assigned to all units for comparison purposes.

Averaging times fo r the opacity limits were not always specified in the permit or in the ICR responses. For units where opacity limits were expected ( e.g., a recovery furnace with an electrostatic precipitator [ ESP ] ), the averaging time for the representative limit was assu med to be the same as the averaging time specified in the NSPS (6

- min averages). For units where opacity limits were not expected ( e.g., a smelt dissolving tank with a scrubber), the averaging

time was not assumed

, and the representative limit did not indi cate an averaging period.

B. Permit Review: Particulate Matter

Particulate matter limits were tabulated from the ICR responses and the state permitting

websites and were analyzed . These limits were specified as PM, PM

- filterable, total PM, and

PM/PM10. Limits for PM and PM

- filterable were considered to be the same, as PM

- filterable is generally referred to as PM (both represent particles that are emitted directly by a source as a solid or liquid at stack conditions and can be captured on the filter of a stack test train)

, and these

emis sions are determined using EPA M ethod 5. Total PM is determined using a combination of

Method 5 and Method 202

, and represents both filterable PM and condensable PM emissions. Condensable PM is material that is in vapor pha se at stack conditions, but condenses and/or reacts upon cooling and dilution in the ambient air to form solid or liquid PM immediately after discharge. The final category, PM/PM10, is measured using EPA M ethod 201 or 201A

, and

determines the PM emissions that have an aerodynamic diameter of equal to or less than 10 micrometers. This test method cannot be performed on wet stacks such as wet scrubber stacks ; therefore

, PM/PM10 limits were only expected for units that use ESPs as their air pollution4 

### control d evice (APCD)

. Because the pulp and paper standards specify filterable PM limits, it is believed that PM/PM10 limits are permit annotations based on state implementation plans for the PM10 National Ambient Air Quality Standards (NAAQS). The PM/PM10 limits a re interpreted as filterable PM limits for comparison to the standard, but are indicated separately in the analyses

in this memo. Representative limits were determined for the emission units in this source category and were categorized as “PM”, “total PM”, and “PM/PM10” in the tabulation spreadsheet.

Averaging times for the PM limits were not always specified in the permit or in the ICR responses. It was assumed that the averaging time was 3

- hours (the length of three runs in a single stack test used for compliance), unless otherwise specified. Based on the ICR responses, no pulp and paper recovery furnaces, SDTs, or lime kilns operate PM continuous emission monitoring systems (CEMS).

C. Permit Review: T otal Reduced Sulfur

Total reduced sulfur limits we re tabulated from the ICR responses and the state permitting

websites and were analyzed . Total reduce d sulfur represents four compounds

-- hydrogen sulfide (H 2 

### S) , methyl mercaptan, dimethyl sulfide, and dimethyl disulfide

-- and is measured and

monitored using EPA M ethod 16 (or alternatively, 16A, 16B, or 16C) and TRS CEMS

, respectively . Method 16 specifies that TRS concentration should be calculated based on H 2 

### S; therefore, we assumed that all permit limits are “as H 2 

### S” unless otherwise specified. Representati ve limits were determined for the emission units in this source category , and were

adde d to the tabulation spreadsheet

.

II I

. Summary of Permit Findings

A. Recovery Furnace Permits

Permits for all 151 of the recovery furnaces in the U.S. were compiled from the ICR responses and the permits from the state websites. Units and corresponding emission limits can be found in

Table B

- 1 in Appendix B.

1. Recovery Furnace Opacity

The NSPS currently requires recovery furnaces that were constructed, reconstruct ed, or

modified after 1976 to meet a 35 percent opacity limit with a 6 percent monitoring allowance that allows the unit to exceed the standard for 6 percent of the 6

- minute averages in a quarter

, without constituting a violation

. This standard was based o n the use of an ESP with a continuous opacity monitoring system (COMS). C u r r e n t l y
, f our recovery furnaces were permitted to use a combination of an ESP and a scrubber to control air emissions, and are thought to have a COMS

between the ESP and the scrubber. Two addit ional furnaces were only permitted to have a scrubber, and are thought to meet the NESHAP limit based on parametric monitoring or a

Method 9 stack test. Permits for m any furnaces (59) specified an opacity limit of 35 percent, but

were silent on the monitor ing allowance ( e.g., referred to the federal rule for details)

, and permits

for 8 units specified the 35 percent opacity limit with the 6 percent monitoring allowance

.5 

### Permits for s even additional units specified a 35 percent opacity limit with several var iations of the monitoring allowance. Overall, it appears that permitted limits for 7 4 recovery furnaces

match the 35 percent opacity limit in the NSPS.

The subpart MM NESHAP requires that new sources meet a 20 percent opacity limit. Similar to the NSPS, t he NESHAP for new sources has a 6 percent monitoring allowance that allows the recovery furnace to exceed the standard for 6 percent of the 6

- minute averages in a quarter.

Permits for m any units (37) specified an opacity limit of 20 percent, but were silen t on the monitoring allowance

. Permits for t hree units specified a 20 percent opacity limit with varying monitoring allowance s . One permit specified that the recovery furnace could exceed 20 percent

for one 6

- minute average per hour, and another permit spe cified the same, with the additional

restraint that the furnace could not exceed 30 percent opaci ty during that period . One furnace had a more stringent monitoring allowance of 2 percent per quarter and 1 percent per year. Overall, it appears that permitte d limits for 40 recovery furnaces match the 20 percent opacity limit of the

new source NESHAP.

Additionally, the subpart MM NESHAP requires that existing sources meet a 35 percent opacity limit based on 6

- minute averages (violation level) and a 20 p ercent opacity limit based

on 10 consecutive 6

- minute averages (corrective action level) . Similar to the NSPS and the new

source NESHAP , the NESHAP for existing sources has a 6 percent monitoring allowance that

allows the unit to exceed the standard for 6 percent of the 6

- minute averages in a quarter. Permits

for e ight units specified an opacity limit of 20 percent for 10 consecutive 6

- minute averages and a 35 percent 6

- minute average, with no monitoring allowance specified. Permits for s ix units specified an opacity limit with the monitoring allowance, not to exceed 40 percent. One

additional permit specified the same limit with the monitoring allowance. Similarly, permits for three units specified a 20 percent opacity limit based on a 1

- hour average and a 35 percent opacity limit based on 6

- minute averages. Overall, it appears that permitted limits for 1 8 recovery furnaces match the 35 percent (with 20 percent corrective action) opacity limit of the existing source NESHAP.

The NESHAP for industrial, commercial, and institutional major source boilers (also known as boiler MACT) requires that boilers meet a 20 percent opacity limit based on 6

- minute averages, and units are allowed to exceed the 20 percent opacity limit for one 6

- minute average per hour, not to exceed 27 percent. Permits for eight recovery furnaces specified a separate limit for periods when the furnace is burning fuel oil, most similar to the boiler MACT. Permits for

t wo units specified the subpart MM NESHAP existing source limit for per iods when black liquor

is burned and the boiler MACT limit for when fuel oil is burned. Permits for t wo units specified a 35 percent opacity limit for periods of burning black liquor and the boiler MACT limit for periods of burning fuel oil

, and permits fo r three additional units specified a 35 percent opacity limit for periods of burning black liquor and a 20 percent opacity limit for periods of burning fuel oil, without the allowance to ex ceed up to 27 percent

. One permit specified a 35 percent opacity li mit for burning black liquor, with the ability to exceed up to 40 percent for periods of startup and shutdown for up to 15 minutes (not to exceed two startup and shutdown events in a

24

- hour period) and a 20 percent opacity limit for periods of burning fue l oil. Overall, eight recovery furnaces had separate permitted limits for burning black liquor and burning fuel oil.6 

### Nine recovery furnaces had permitted opacity limits that were different from , but no less stringent than, the federal regulations. One uni t was permitted to meet a 30 percent opacity limit

based on 6

- minute averages. One unit was permitted to meet a 60 percent 1

- minute average, a 35 percent 6

- minute average, and a 20 percent average based on 10 consecutive 6

- minute averages

, with the ability to exceed 20 percent for no more than 3 minutes per hour. One unit had a 20 percent opacity limit based on 3

- minute averages, not to exceed 35 percent

. Two units had a separate opacity limit for periods of startup and cleaning. These units had a 20 percen t opacity

limit based on 6

- minute averages for periods of normal operation and an 80 percent (6

- minute) limit for startup and cleaning periods, not to exceed more than 6 minutes in any ho ur. Two units were permitted to meet 20 percent opacity (6

- minute ave rage) and up to 35 percent during startup and shutdown, not to exceed 4 hours per event. One unit had a 25 percent hourly opacity limit and a 35 percent 6

- minute average, and one unit had a 30 percent 6

- minute average not to

exceed for more than one 6

- minu te average in a 3

- hour period.

Interestingly

, two units had opacity limits that were less stringent than all of the federal regulations ( i.e., subpart MM NESHAP, NSPS, and boiler MACT). One of these units had an opacity limit of 40 percent based on 6

- minute averages without a monitoring allowance specified

. Th is is the Louisiana state limit, and t his unit complies with subpart MM through a monitoring alternative ( § 60.84(e)(13) ) by measur ing ESP total power every 15 minutes and

meet ing the minimum requi rements on an hourly basis. One unit had a permitted opacity limit of 40 percent with a monitoring allowance. This unit wa s allowed to exceed the 40 percent for one

6

- minute period per hour, not to exceed 4 per 24

- hour period, up to 90 percent opacity. Thi s is

the North Caro lina opacity limit. Subpart MM wa s applicable to this unit and mentioned in the permit, but opacity values were not explicitly stated.

Table 1 below summarizes the representative opacity limits for recovery furnaces and the

number of un its subject to each limit, as discussed above.7

### 2. Recovery Furnace Particulate Matter

The NSPS an d the subpart MM NESHAP for existing sources require units to meet a filterable

PM limit of 0.044 grain s per dry standard cubic foot ( gr/dscf ) . The PM bubble in the subpart

MM NESHAP allows facilities to determine facility

- specific PM emission limit s for th eir existing recovery furnaces, SDTs, and lime kilns, the sum of which must be no higher than the

combination of the promulgated PM limits for these emission unit s . The facility can trade

emissions amongst these units to derive this sum . The NSPS does not have this provision ; therefore, units that are subject to the NSPS must meet the NSPS limits. All of the recovery

furnaces

, except for three

, were permitted for the NSPS limit or lower; these three units were not subject to the NSPS and were located at faci lities that participate in the PM bubble compliance

alternative.

The subpart MM NESHAP also requires that new and reconstructed units meet a filterable PM limit of 0.015 gr/dscf. Three furnaces were permitted to meet the new source limit, one as a

filtera ble PM limit and two as a PM10 limit. O ne of these furnaces wa s not a new unit (modified in 2005), but ha d a more stringent limit because it wa s a credit source for the facility’s PM

bubble compliance alternative.

Forty

- one units were permitted to meet PM limits between 0.02 gr/dscf and 0.03 gr/dscf, and

12 of these units are located at facilities that utilize the PM bubble compliance alternative. Two

units were permitted for an annual average of 0.02 gr/dscf, but were required to meet a 3

- hour average of 0.044 gr/dscf for stack tests. It is thought that compliance with the annual average is based on parametric monitoring. Two units had filterable PM limits of 0.021 gr/dscf, but were also required to meet separate total PM limits (0.0238 and 0.0298 gr/dscf)

. Two units were permitted for 0.027 gr/dscf on an hourly basis and both have an additional annual PM limit (0. 0 2 gr/dscf and 0. 0 21 gr/dscf). One unit ha d a filterable PM limit of 0.027 gr/dscf and an additional total PM limit of 0.034 gr/dscf. One unit wa s also permitted for 0.029 gr/dscf on an annual basis

. Thirty units were permitted to meet PM limits between 0.03 gr/dscf and 0.043 gr/dscf, and 18 of

these units are located at facilities that utilize the PM bubble compliance alternative. Two units

ha d se parate PM and PM10 limit s
, and two units ha d limits specified based on a 1

- hour average

.

The remaining 7 4 units were permitted to meet the NSPS and existing source NESHAP limit of 0.044 gr/dscf

. The permit for o ne unit specifie d a limit based on a 1

- hour average. One permit specifie d a daily average as determined by an opacity correlation. One permit specifie d a 3

- hour average and had an additional 1

- hour average requirement of 0.05 gr/dscf. Finally, one unit wa s permitted to m e e t 0.044 gr/dscf based on a daily average and also ha d a separate 3

- hour average

limit of 0.033 gr/dscf

. For this unit, it is believed that compliance with the daily average is based on parametric monitoring and compliance with the 3

- hour average is based on a stack test.

Table 2 below summarizes the representative PM limits for recovery furnaces and the number of units subject to each limit, as described above. Total PM and PM/PM10 limits are distinguished with asterisks (** and *, respectively) in this table and in Table B

- 1 in the appendix

. Filterable PM limits do not include an asterisk.9

### 3. Recovery Furnace Total Reduced Sulfur

The NSPS require that DCE and NDCE recovery furnaces constructed, reconstructed, or

modified after 1976 limit t heir TRS emissions to 5 parts per million ( ppm ) . The regulation requires continuous TRS monitoring with a 12

- hour averaging period for reporting

, and also

contains a 1 percent monitor ing allowance that allows 1 percent of the 12

- hour averages in a

quarter to exceed the 5 ppm limit. The monitoring allowance was not included in the representative limit unless it varied from the current allowance of 1 percent. The TRS emission guideline limits of 20 ppm for DCE furnaces and 5 ppm for NDCE furnaces have general ly been adopted for recovery furnaces that have not triggered NSPS to date. Of the 151 recovery furnaces, 101 were permitted to meet a limit similar to the NSPS

, and 9 3 of the se units were permitted exactly as the NSPS reads (5 ppm based on 12

- hour average ).

F our units (all NDCEs) were permitted for a TRS value more stringent than t he current NSPS

. Two of these units ha d a TRS limit of 3 ppm; one unit was based on a 3

- hour average

, and one

unit wa s based on a 12

- hour average. Two units ha d a TRS limit of 4 ppm; the TRS limit for one unit wa s based on a 12

- hour average

, and the TRS limit for the other unit wa s based on a 24

- hour average and was not allowed to exceed 8 ppm for more than 60 minutes per day. Two units were permitted at 5 ppm based on 12

- hour av erages and had additional requirements. One of these

unit s ha d a 4.3 ppm limit ba sed on a 24

- hour average, but was also required to meet the NSPS limit of 5 ppm based on 12

- hour averages, as well as a 10 ppm 2

- hour average limit. The other

unit wa s permitt ed to meet the 5 ppm 12

- hour average, but also ha d a separate 4 ppm H 2 

### S limit.

Three units showed compliance with 5 ppm using a 1

- hour average

, and three units showed compliance with the limit using a 24

- hour average.

There were 38 units permitted for TR S limits between (and includin g) 10 ppm and 20 ppm.

One unit wa s permitted to meet a 10 ppm TRS limit and a 4 ppm H 2 

### S limit. This unit wa s an NDCE not subject to the NSPS. Four DCEs not subject to the NSPS were permitted to meet 10 ppm based on a 24

- hour a verage. One NDCE not subject to the NSPS wa s permitted to meet a 15 ppm limit based on a 12

- hour average , and another unit wa s permitted to meet 15 ppm based on

a 24

- hour average . O ne DCE not subject to the NSPS wa s permitted to meet a 15 ppm limit

based o n a 24

- hour average with no more than 60 1

- minute spikes above 40 ppm in a 24

- hour period. Seven units ( four NDCE and three DCE) were permitted to meet a 17.5 ppm limit based

on 12

- hour averages

, and one of these units (a DCE subject to the NSPS) had a yea rly TRS limit

of 11.5 ppm. One additional DCE was required to meet a 17.5 ppm limit, but based on a 24

- hour

average. Seventeen units (including five NDCEs) were required to meet a 20 ppm TRS limit

based on a 12

- hour average. Three of these units ha d additi onal requirements including a 4.5 ppm limit based on a 12

- month rolling average for one unit and a 50 ppm 1

- hour limit for two

units. Five units (including one N DCE) were required to meet a 20 ppm limit based on a 24

- hour averaging period.

Two units were required to meet a 35 ppm limit based on a 12

- hour average, and five units (including one NDCE) were required to meet a 40 ppm limit based on a 12

### B. Smelt Dissolving Tank Permits

Permits for a total of 160 of 164 SDTs in the U.S. were compiled from the ICR responses and the permit s from the state websites. Units and corresponding emission limits can be found in

Table C

- 1 in Appendix C.

1. SDT Opacity

Because SDTs use wet scrubbers to remove PM, continuous opacity monitoring is not appropriate due to moisture in the stack gas whi ch interferes with opacity readings. Neither the NSPS nor the subpart MM NESHAP require opacity monitoring for SDTs ; however

, 99 units had opacity limits in their permits. The opacity limits found in the permits ranged from 5 percent to 40 percent and had various monitoring frequencies. It is thought that these requirements are12 

### overarching state

- specific requirements broadly applicable to various industrial sources and are likely met using parametr ic monitoring or EPA Method 9 opacity testing. No opacity li mits were required for 60 SDTs

, consistent with the NSPS and subpart MM NESHAP.

The majority of the SDTs with an opacity limit had a numerical limit of 20 percent (73 out of 99 units). Of these units, 24 were required to meet a 20 percent opacity based on a 6

- minute average. Twelve additional units had a monitoring allowance specified, with some containing an upper opacity limit resulting in a violation if exceeded. The permit of o ne unit specifie d a measurement once per shift

, and one unit specifie d an op acity test (assumed to be Metho d 9). Thirty additional units did not specify the frequency of the monitoring and only had a numerical limit of 20 percent.

Of the remaining 26 units, 2 units had an opacity limit lower than 20 percent . These two units

had a limit based on 6

- minute averages

, with numerical values of 5 percent and 10 percent. Two units specif ied a 30 percent limit based on a 6

- minute average

, and five units specif ied a 35 percent limit with no averaging time specified. Eighteen units had a num erical limit of 40 percent opacity. Table 4 below summarizes the representative opacity limits for SDTs and the number of units subject to each, as discussed above.

### 2. Smelt Dissolving Tank Particulate Matter

The NSPS currently requires SDTs t hat were constructed, reconstructed, or modified after

197 6 to meet a PM limit of 0.2 pound per ton of black liquor solids ( lb/ton BLS ) . The subpart MM NESHAP requires existing SDTs to meet the same PM limit. Of the 160 unit s for which permits were reviewe d, 117 were permitted to meet 0.2 lb./ton BLS . The majority demonstrated compliance based on filterable PM (86 units)

, and several were indicated as PM10 (30). Since the PM10 method is not appropriate for wet stacks, it is believed that these limits are

de monstrated using Method 5, and are labeled as PM10 due to state implementation plans for the NAAQS. One unit was permitted to meet a 0.2 lb/ton BLS 3

- hour average and a 0.3 lb/ton BLS hourly average ( e.g. each hourly test run)

.

The PM bubble in the subpa rt MM NESHAP allows facilities to determine facility

- specific

PM emission limit s for their existing recovery furnaces, SDTs, and lime kilns, the sum of which must be no higher than the combination of the promulgated PM limits for these emission unit s

. The facility can trade emissions amongst these units to derive this sum . The NSPS does not have this provision, therefore, units that are subject to the NSPS must meet the NSPS limits. All of the

SDTs for which permits were available except for 14 were permitt ed for the NSPS limit or lower; these units were not subject to the NSPS and were located at facilities that utilize the PM bubble complia nce alternative

.

The subpart MM NESHAP also requires that new and reconstructed SDTs associated with

new and reconstr ucted recovery furnaces meet a filterable PM limit of 0.12 lb/ton BLS. A total

of 19 units were permitted to meet this limit, 2 of which were units that were not characterized as new, and ha d lower limits because they were credits for the PM bubble complia nce alternative at their facility. Three units were required to meet the limit based on a 1

- hour average. Eight units were permitted to meet the limit based on filterable PM

, and the remaining eight units were permitted to meet the limit based on PM10 test s. It is assumed that these units must meet the

limit based on a 3

- hour stack test

, even though it was not specified. Ten units were permitted to meet PM limits (both filterable and PM10) between 0.12 and 0.2 lb/ton BLS, and three of these

unit s were locat ed at facilities that utilize the PM bubble compliance alternative. Table 5 summarizes the representative PM limits for SDTs and the number of units subject to each limit,

as discussed above.14

### 3. Smelt Dissolving Tank T otal R educed S ulfur

The original NSPS (promulgated in 1978 ) required SDTs to meet a TRS limit of 0.0168 lb/ton BLS. Emission guidelines were also p ublished in 1979 with a limit of 0.0168 lb/ton BLS for existing SDTs. Current permits for 3 4 SDTs contain a limit of 0.0168 lb/ton BLS . A review of the NSPS in 1986 revealed that units could not always meet 0.0168 lb/ton BLS even if they were using best demonstrated technology. As a result, the 1986 NSPS review revised the limit to
0.033 lb/ton BLS. Today, approximately half of SDTs (82 units) are permitted to m eet 0.033

lb/ton BLS

.15 

### Twenty units were permitted between limits of 0.0168 and 0.033 lb/ton BLS , with the majority (15) permitted at 0.032 lb/ton BLS. Five units were permitted to meet li mits higher than the NSPS limit and range between 0.0336 lb/ton BLS and 0.066 lb/ton BLS. Twelve units ha d no apparent TRS limit specified in their permit

, and seven units ha d a site

- specific concentration or a mass limit specified. Table 6 summarizes the representative TRS limits for SDTs and the number of units subject to each limit.

### C . Lime Kiln Permits

Permits for a total of 130 of the 131 lime kilns in the U.S. were compiled from the ICR

respo nses and the permits from the state websites. Units and corresponding emissio n limits can

be found in Table D

- 1 in Appendix D

.

1. Lime Kiln Opacity

The NSPS does not currently require opacity monitoring for lime kilns because scrubbers

were the best demo nstrated technology during promulgation and during the 1986 review. Opacity monitoring for scrubber stacks is not appropriate because the stack gas contains

moisture

, which interfere s with the opacity readings . The subpart MM NESHAP

, however, requires opac ity monitoring on units equipped with ESPs. Of the 130 permits reviewed, 38 lime16 

### kilns with ESPs were identified

, i ncluding ESP

- scrubber combination controls . Under the NESHAP, the ESP

- controlled lime kiln opacity limit is 20 percent based on 6

- minute avera ges. Similar to the monitoring allowance for recovery furnaces, lime kilns with ESPs are allowed to exceed 20 percent opacity for 6 percent of the 6

- minute averages in a quarter without being

considered in violation

.

The majority of the lime kilns (10 2 o f 130) were permitted to meet an opacity limit, regardless of APCD, and 76 of these units were permitted to meet a 20 percent limit. Twenty

s even of these units utilize d ESPs as their APCD, 11 utilized a SCBR/ESP combination, and t he

remainder (38) utiliz e d scrubbers. It is thought that the units with opacity limits that do not utilize an ESP show compliance through a visual opacity test (EPA Method 9) or through parametric monitoring. Twelve units specified an upper limit on the times during which the

monitoring allowance was used, ranging from 27 percent to 87 percent.

Twenty

- six units were permitted to meet an opacity limit greater than 20 percent. Two of

these units used ESPs with state permitted limits of 40 percent and 25 percent. The remaining

units utilized scrubbers

, and it is thought that the opacity limits for these units are general state requirements broadly applicable for industrial equipment for which compliance is demonstrated through parametric monitoring or through visual opacity testing ( i .e., there is no continuous opacity monitoring)

. Table 7 below summarizes the representative opacity limits for lime kilns and the number of units subject to each limit, as discussed above.17

### 2. Lime Kiln Particulate Matter

The NSPS currently requires lime kilns burning gas to meet a 0.066 gr/dscf filterable PM limit, and kilns burning liquid fuel oil to meet a 0.13 gr/dscf filterable PM limit. The subpa rt MM NESHAP requires existing kilns, regardless of fuel type, to meet a limit of 0.064 gr/dscf, and new kilns to meet 0.01 gr/dscf. The PM bubble in the subpart MM NESHAP allows facilities to determine facility

- specific PM emission limit s for their existi ng recovery furnaces, SDTs, and lime kilns, the sum of which must be no higher than the combination of the promulgated PM

limits for these emission unit s . The facility can trade emissions amongst these units to derive this

sum . The NSPS does not have this provision; therefore

, units that are subject to the NSPS must

meet the NSPS limits. All of the lime kilns for which permits were available except for five were permitted for the NSPS limit or lower. These units were not subject to the NSPS

, and four were

l ocated at facilities that utilize the PM bubble compliance alternative. The remaining unit specified a 24

- hour average PM limit of 0.2 gr/dscf. It is assumed that compliance for this unit is demonstrated using parametric monitoring on a daily basis.

Even though the subpart MM NESHAP removed the distinction between kiln fuel types, 18 kilns were permitted with separate limits for periods of gas

- fired and liquid fuel

- fired burning. The gas

- fired kiln limits ranged from 0.035 gr/dscf to 0.067 gr/dscf, with se ven units permitted

to meet 0.064 gr/dscf while burning gas and 0.13 gr/dscf while burning fuel oil (a combination of the NESHAP and the NSPS limits). Four units were permitted to be more stringent than both standards, while maintaining different limits fo r gas

- and liquid fuel

- fired periods, and two of these units were located at facilities participating in the PM bubble compliance alternative. One unit had a less stringent limit for periods of burning fuel oil (0.2 gr/dscf)

, and six units had a less

strin gent limit for periods of burning gas. These six units were subject to the PM bubble.

A total of 17 units were permitted below 0.064 gr/dscf with no fuel distinctions. Two units were permitted to meet the new source NESHAP limit of 0.01 gr/dscf

. The remai ning 15 units had permitted values between 0.0125 and 0.056 gr/dscf, with three located at facilities that utilize the PM bubble compliance alternative.

Over half of the kiln s (72) were permitted to meet the NESHAP limit of 0.064 gr/dscf

, and 8

were p ermitted to meet the liquid fuel

- fired NSPS limit of 0.13 gr/dscf. The remaining 10 units were permitted between 0.065 and 0.12 gr/dscf, with 9 being located at facilities that participate in the PM bubble compliance alternative. Table 8 summarizes the rep resentative PM limits for lime kilns and the number of units subject to each limit, as discussed above.19

### 3. Lime Kiln T otal Reduced Sulfur

The NSPS requires that lime kilns constructed, reconstructed, or modified after 1 976 limit their TRS emissions to 8 ppm. The regulation requires continuous TRS monitoring with a 12

- hour averaging period for reporting. Of the 130 lime kilns for which permits were available , 57 were permitted to meet 8 ppm. Three of these units also had a 2

- hour maximum limit of 80 ppm.

F our kilns were permitted at a more stringent limit. Two of these units were required to meet a 5 ppm limit, two were required to meet a 7 ppm limit (all based on 12

- hour averages)

. O ne kiln was required to meet a 7.5 ppm limit based on a 24

- hour average with a 10 ppm hourly average

limit

.

The emission guidelines require existing lime kilns to limit their TRS emissions to 20 ppm. There were 50 units permitted to meet this limit. Six of these units demonstrate compliance o n a 24

- hour basis, and five additional units must not exceed 80 ppm for more than 2 hours. One unit

has a 12

- hour 20 ppm limit as well as a 50 ppm 1

- hour limit. State regulations in three states (Georgia, Ohio, and Arkansas) specify higher TRS limits of 40 ppm and 50 ppm, and 12 units were permitted to meet these limits. Five units had no apparent TRS limits in their permits, and

one unit had a mass

- based limit (tons per year) instead of concentration. Table 9 summarizes the representative TRS limits for li me kilns and the number of units subject to each limit, as

discussed above.

. NCG Source Permits

Non

- condensable gas source permits for 97 kraft pulp mills were reviewed and tabulated to
determine which regulatory option each mill uses to comply with the NSPS limit for TRS from condensate strippers, digesters, evaporators, and brown stock washers. The NSPS requires that any gases from these systems that contain more than 5 ppm, corrected to 10 percent oxygen be treated using one of the foll owing methods:

1. C ombust gases in a lime kiln subject to subpart BB; or

2. Combust gases in a recovery furnace subject to BB; or

3. Combust gases in an incinerator or other device and are subjected to a minimum temperature of 1200 ° F for at least 0.5 second; or

4. D e monstrate to the Administrator that combustion of gases from brown stock washer systems is technologically or economically unfeasible; or

5. Control gases by a means other than combustion (with a limit of 5 ppm, uncorrected for oxygen content).

Condensate strippers were located at 56 of the 97 kraft pulp mills for which we have permit data, and all of the stripper off

- gases (SOGs) were treated by combustion. The majority of the

mill s (33) were permitted to treat SOGs using a standalone incinerator or a boi ler. Other mills (14) were permitted to treat SOGs by combustion in a lime kiln or a recovery furnace subject to subpart BB. These facilities were permitted to use either a lime kiln or a recovery furnace as the main control device, with the other unit as the backup control device. Two additional strippers were permitted a t 5 ppm based on combustion control ( assumed t o be either a recovery furnace

or boiler ) . Six strippers were permitted to use a thermal oxidizer for treatment, and one

additional stripper was permitted to route SOGs to a methanol rectifier system

, followed by

combustion at 1450 ° F for 0.15 seconds.

Digester systems at all of the facilities were permitted to treat gases using incineration. The majority of the systems (56) were permitted to treat the gases using a standalone incinerator or a

boiler. Other digester s (32) were permitted to treat the gases by combustion in a lime kiln or a recovery furnace

, and 5 additional units were permitted at 5 ppm or 8 ppm based on combustion

control i n a recovery furnace or a lime kiln, respectively. Four units were permitted to use a

thermal oxidizer for treatment.

Similar to digester systems, a ll of the evaporator systems were permitted for incineration

control

. The majority of the systems (57) were permitted to treat gases using a standalone incinerator or boiler. Other units (31) were permitted to treat the gases by combustion in a lime kiln or a recovery furnace, and 4 additional units were permitted at 5 ppm or 8 ppm based on

combustion control i n a recovery furnace or a lime kiln, respectively. Four units were permitted

to use a thermal oxidizer for treatment

, and one additional unit was permitted to route SOGs to a methanol rectifier system followed by combustion at 1450 ° F for 0.15 seconds.

Many brown stock washer systems (at 36 facilities) achieve compliance with subpart S through the C C A or were exempt from the NSPS because of the diffusion washer exemption.

Three facilities used controls other than combustion to reduce the TRS emissions to below 522 

### ppm, but the majority (58) were permitted to treat gases through combustion, either by a recovery furnace or lime kiln (18), or by an incinerator or boiler ( 40 ).

A summary of the TRS limits found in permits for condensate strippers, digeste r s, evaporators, and brown stock washers is provided in Table E

- 1 of Appendix E.

. Incinerator Control Device Permits

Kraft mills use incineration control devices ( e.g, thermal oxidizers) as primary or backup

controls to (1) oxidize malodorous TRS emis sions from NCG sources to SO 2 

### under the NSPS (or state limits derived from the emission guidelines)

, and (2) destroy organic HAP emissions under the subpart S NEHSAP. Because they target different pollutants, the subpart BB NSPS and subpart S NESHAP each s pecify a different minimum temperature and retention time for

incineration control devices. Subpart BB specifies a minimum temperature of 1200 o 

### F for TRS control, while subpart S specifies a higher temperature of 1600 o 

### F for HAP control. Neither rule prescri bes a specific averaging time or recording frequency for temperature, though subpart BB specifies excess emissions periods in excess of 5 minutes when the minimum temperature is not

ach i e ved. (Retention time is an incinerator design value that is not monit ored.) The NCG source permits involving incineration controls were reviewed for information on retention times, minimum temperature limits (including any site

- specific temperature limits), temperature recording frequency, and temperature averaging times. T he incinerator parameters for 23 incinerators (at 20 facilities) were tabulated

. It was observed that many of the permits did not indicate a temperature averaging time. Varying averaging times from 5 minutes to 24 hours were indicated for those with permit s that specified them. Of these units, five were permitted based on

3

- hour averages, two were permitted based on 5

- minute averages, one was permitted based on a

24

- hour average, and one was permitted based on a 1

- hour average. The majority (16 units)

recor ded temperature continuously and reported the time during which the incineration temperature was below the minimum temperature based on 5

- minute intervals. Additionally,

three units recorded temperature once per shift, and two units recorded temperature ev ery 15

minutes. Because the temperature requirement for subpart S is 1600 o 

### F and facilities can demonstrate compliance at a lower temperature, many site

- specific minimum temperatures were determined for the incinerators, ranging from 1200 ° F to 1500 ° F. Table F

- 1 in Appendix F shows a summary of the reviewed incinerator permits.A
