Re: New Source Performance Standards for Nitric Acid Plants

Dear Bill: 

On behalf of The Fertilizer Institute (“TFI”), we want to thank you and others at the U.S. 

Environmental Protection Agency (“EPA” or “Agency”) for meeting with us on March 15, 2012, 

to discuss the Agency’s proposed rule entitled New Source Performance Standards for Nitric 

Acid Plants,

1

 appearing at 76 Fed. Reg. 63878 (Oct. 14, 2011). As you are aware, TFI submitted 

comments on this rulemaking and TFI and its members have a substantial interest in EPA’s 

development of the final rule.2

 During our meeting, EPA requested four items from TFI and its 

members: (1) a definition of extended absorption; (2) any additional continuous emissions 

monitoring system (“CEMS”) data that TFI members may possess for nitric acid plants 

(“NAPs”); (3) a discussion of nonselective catalytic reduction (“NSCR”); and, (4) any support 

for the subcategorization of NAPs in the final New Source Performance Standards for Nitric 

Acid Plants based on prior EPA rulemakings. TFI responds to EPA’s requests below.3

I. Definition of Extended Absorption

As EPA is aware, the production of nitric acid is basically a three step process. First, anhydrous 

ammonia is oxidized over a catalyst (typically platinum-rhodium gauze) to product nitrous oxide

(EPA-HQ-OAR-2010-0750-0120).

 We also request that EPA place this letter in the rulemaking docket.

and water. Second, the nitrous oxide formed from the first step is cooled in a cooler/condenser 

apparatus, where it is reacted with oxygen to form nitrogen dioxide and dinitrogen tetroxide. 

Third, the nitrogen dioxide and dinitrogen tetroxide are absorbed in water to form nitric acid and 

NOx. This absorption takes place in a stainless steel absorption tower containing numerous 

bubble cap or sieve trays. The number of trays vary according to the design pressure, acid 

strength, gas composition, and operating temperature. 

“Extended” absorption reduces NOx emissions by increasing the absorption efficiency in the 

production process. Extended absorption typically means a single large tower or the addition of 

a second absorption tower in series with the first absorption tower. As noted by EPA, although 

extended absorption (either through a larger absorption tower or a second absorption tower) 

results in more NOx being recovered to produce nitric acid (approximately 1 to 1.5 percent more 

nitric acid), the principal purpose of the extended absorption tower is to reduce NOx emission 

levels (typically 100 ppm).4 Consistent with this recognition, EPA identifies extended 

absorption as a pollution control technique for NOx.

5

The gas off the extended absorption unit is sent to a series of heat exchangers and, from there, 

typically to a NOx pollution control device. The “larger” the extended absorption unit, the more 

NOx reduction up-stream of the pollution control device and, consequently, the lower the NOx

concentration entering the pollution control device. 

As noted in TFI’s comments on the Nitric Acid NSPS Proposal, the El Dorado Nitrogen and PCS 

Geismar Train 5 extended absorption units are larger than typical in the industry, which means 

that the outlet NOx concentrations from their extended absorption units to the pollution control 

devices are lower than typical.6 This results in lower NOx concentrations exiting the SCR 

pollution control device on each NAP.7

II. Additional CEMS Data

EPA asked TFI if its members with CEMS on their NAPs would be willing to share the CEMS 

data with the Agency. In the time period allotted TFI by EPA to provide such data to the 

 

4

 See EPA, Alternative Control Techniques Document – Nitric and Adipic Acid Manufacturing Plants at 5-2 

(Dec. 1991) (hereinafter “Alternative Control”). 5

 Id. at 5-1–5-6. 6

 For example, the El Dorado Nitrogen selective catalytic reduction (“SCR”) device has an inlet NOx

concentration of about 300 to 800 ppm NOx, which is not typical, particularly for older NAPs which have an inlet 

concentration in the range of 1,500 to 2,000 ppm NOx. See TFI Comments at 11. EPA recognized that the size of 

the extended absorption tower is a factor relevant to the NOx concentration exiting the tower. See Alternative 

Control at 5-5 (stating that the factors leading to reduced NOx concentrations exiting an extended absorption tower 

include the residence time in the tower – that is, the larger the tower, the longer the residence time and, as a result, 

the lower the exiting NOx concentration). 7

 In addition, these test plants have unique capabilities that allow either the SCR device to remain on during 

startup and shutdown (El Dorado Nitrogen, due to an unlimited steam supply) or the SCR to obtain optimum 

operating temperature sooner (PCS Geismar Train 5, due to a steam heater upstream of the SCR that is used during 

startup). See TFI Comments at 11.

Agency, we have received 2010–2011 monitoring data from Agrium U.S. Inc. (“Agrium”) for its 

West Sacramento NAP, which are included as Enclosures A and B. We will forward any 

additional data we receive from members to EPA upon receipt. 

The Agrium West Sacramento NAP was originally constructed in 1982 and has NSCR for NOx

pollution abatement. This NAP was one of EPA’s test plants in the Nitric Acid NSPS Proposal.

8

 

The West Sacramento NAP does not have extended absorption. In the Nitric Acid NSPS 

Proposal, EPA concluded that the NOx 99th percentile, 30-day rolling average for this NAP is 

1.29 lb/ton.9

 

Using the recent Agrium data, and EPA’s methodology for the Nitric Acid NSPS Proposal, we 

calculated a 99th percentile, 30-day rolling average for this NAP of 1.53 lb/ton NOx. This result, 

based on more recent CEMS data, is higher than EPA’s reported 1.29 lb/ton for this NAP. In 

addition, the Agrium NAP, as is the case with the majority of TFI members’ NAPs, utilizes a 

single span NOx monitor, which peaks at 500 ppm. Because startup and shutdown events at 

NAPs result in NOx emissions in the range of 2,000–5,000 ppm, the 99th percentile, 30-day 

rolling average would be higher if the NOx emissions during startup and shutdown were 

monitored using a dual span monitor.10 

The Agrium West Sacramento NAP data further confirm that an existing NAP with NSCR will 

not be able to meet the proposed 0.5 lb/ton NOx standard. Further, the lack of a dual span 

monitor for this NAP undercuts EPA’s Nitric Acid NSPS Proposal because, under the proposal, 

NAPs are required to measure emissions at all times (including startup and shutdown), and such 

emissions are factored into compliance. Because EPA’s assumption capped startup and 

shutdown emissions at 500 ppm (due to the limitations of CEMS as calibrated under Subpart G), 

EPA’s proposed NSPS does not accurately account for actual startup and shutdown emissions. 

III. NSCR Discussion

The NSCR process involves the non-selective catalytic reduction of NOx to nitrogen using a 

catalyst. As the process is non-selective, the oxygen in the tail gas needs to be combusted before 

the NOx reduction can take place. This results in a substantial generation of heat in the process, 

which is then recovered. NAPs utilizing NSCR technology are integrated so that optimum 

utilization of heat generated in the process is achieved. The heat is recovered through steam 

generation, tail gas reheating, water heating, etc., utilizing a number of heat exchangers within 

the process battery limits. In addition to the NOx reduction, the NSCR process offers several 

advantages: 

 The exothermic reaction heat generated during the NSCR process is typically used for 

driving the air compressor (through a tail gas expander). Approximately 70-90% of the

horsepower requirement of the air compressor is met in this manner. The air compressor 

is the single largest power consumer in the process. Alternate technologies may need 

supplemental power to be provided through an electric motor or steam turbine. 

 Additional heat recovery from tail gas is possible through the use of boiler/economizer 

systems. Optimum steam recovery is critical for the site steam balance and, if not 

optimized, may need to be supplemented through generation of steam from auxiliary 

boilers. 

 The reaction taking place in the nitric acid process is highly exothermic, and part of the 

heat generated is utilized for preheating the tail gas to the minimum temperature needed 

for reaction in the NSCR process. An alternate process may require significant changes 

to the heat train, resulting in higher capital costs. 

 A significant amount of N2O generated upstream is destroyed during the reduction 

process (typically in the 70-80% range). 

During our meeting, we discussed NAPs with NSCR and how these NAPs would have difficulty 

meeting the proposed 0.50 lb/ton NOx standard, based on a 30-day rolling average.11 Indeed, 

EPA expressed uncertainty in the Nitric Acid NSPS Proposal preamble about whether the 

proposed standard would be achievable for these NAPs,12 a fundamental requirement for setting 

a NSPS.13 Based on this uncertainly, TFI advocated in its comments that EPA set a separate 

NOx emission limit for existing NSCR-controlled NAPs that undergo a modification or 

reconstruction.14

There are several advantages inherent with NSCR-controlled NAPs that may no longer be 

present if the installation of SCR is required for a modified/reconstructed NSCR-controlled NAP 

to meet the proposed standard. NSCR is built into, and is an integral part of, the operation of the 

NAP, particularly in terms of heat balance and energy generation for other parts of the NAP. As 

such, NAPs with an NSCR must keep temperatures elevated in order to create the reductive 

environment within the unit that eliminates both NOx and N2O. In order to ensure that 

temperatures and pressures are adequate for this reductive environment, the NSCR is placed 

upstream of the tail gas expander. These expanders will malfunction above the temperatures 

they are designed to handle, and because NSCR reactions are extremely exothermic, any 

increased NOx destruction and associated temperature increases related thereto could cripple the 

expander and, thus, the entire NAP. Attempting to switch to alternate technologies, or the 

 

11 The proposed standard is based on the identification of SCR as the best demonstrated technology. 76 Fed.

is uncertain. . . . These data are presented to show that NSCR may be able to achieve the proposed emission limit.”). 13 Section 111 of the Clean Air Act (“CAA”) requires that a NSPS “reflect[] the degree of emission 

limitations achievable . . .”, not the degree of emission limitations that may be achievable. 42 U.S.C. § 7411(a)(1). 14 See TFI Comments at 23.

insertion of additional abatement technologies, can have a significant impact on capital cost as a 

result of modifications/addition to the heat trains.15 Other NAPs do not face these conditions, 

limitations, or the inability to modify their operations, or their attendant impact on emissions.16 

In addition, there may be footprint issues associated with the installation of SCR at an existing 

NSCR-controlled NAP. 

IV. Precedent for Subcategorization of the Nitric Acid Source Category

In our comments, TFI advocated for subcategorization of NAPs, particularly: (1) a NOx standard 

for new NAPs; (2) a NOx standard for existing NAPs without NSCR that undergo a modification 

or reconstruction; and, (3) a NOx standard for existing NAPs with NSCR that undergo a 

modification or reconstruction. Based on our review of CAA § 111, relevant case law, other 

EPA NSPS, as well as certain National Emission Standards for Hazardous Air Pollutants, we 

believe that ample precedent exists for such an approach. 

CAA § 111 directs EPA to set NSPS for categories of stationary sources.17 In doing so, it 

requires EPA to weigh the cost, energy requirements, environmental impacts, and any nonair 

quality health impacts related to such standards.18 It also authorizes EPA to “distinguish among 

classes, types, and sizes within categories of new sources for the purpose of establishing such 

standards.”19 EPA has long interpreted its authority under Section 111 to permit it to set nonuniform NSPS for facilities within a source category; that is, to set different NSPS for 

subcategories of facilities within a source category.20 The Sierra Club v. Costle case is 

instructive.21

In 1979, EPA promulgated sulfur dioxide (“SO2”) and particulate matter NSPS for coal-fired 

electric power plants. The SO2 standard was variable in that it limited emissions to 1.2 lbs/MBtu 

and no less than a 90% reduction of potential uncontrolled SO2 emissions, except when 

emissions were below 0.60 lbs./Mbtu after instituting control measures. When emissions were 

below 0.60 lbs./MBtu, a plant was only required to reduce potential uncontrolled emissions by 

no less than 70%.22 The variable standard was created, among other reasons, to account for the 

 

15 The capital costs associated with modifications to the heat train for a modified NSCR-controlled NAP have 

not been examined by EPA. 

16 See TFI Comments at 12–13. 17 42 U.S.C. § 7411(b)(1)(A)–(B). 

18 Id. § 7411(a)(1). 

19 Id. § 7411(b)(2). Like CAA § 111, Section 112, which requires EPA to set standards for the emission of 

hazardous air pollutants from stationary sources, also allows EPA to distinguish among classes, types, and sizes of 

sources within categories. 42 U.S.C. § 7412(d)(1); see also id. § 7429(a)(1)–(2) (directing EPA to categorize and set 

NSPS for each category of solid waste incineration units and authorizing EPA to distinguish among classes, types, 

and sizes of units within each category). 20 Sierra Club v. Costle, 657 F.2d 298, 318–319 (D.C. Cir. 1981); see also Lignite Energy Council v. EPA, 

198 F.3d 930, 933 (D.C. Cir. 1999) (noting that in 1979 EPA subcategorized utility boilers based on boiler type and 

fuel type and set a range of NSPS for NOx). 21 657 F.2d 298 (D.C. Cir. 1981).

varying amounts of sulfur in coal used as fuel for these plants across the country, as well as 

differences in emission controls (i.e., wet and dry scrubbing).23 

Sierra Club challenged the variable NSPS, asserting that EPA did not have the authority under 

Section 111 to create a non-uniform standard within a source category. The court rejected this 

argument, holding that CAA § 111 provides “on its face that EPA does not have to set a uniform 

percentage reduction requirement for an entire category of emission sources.”24 The fact that 

Congress required EPA to consider and balance costs, environmental, and energy factors when 

setting an NSPS means that Congress “surely could not have meant to bind [EPA] to issuance of 

a uniform standard.”25 

More recently, EPA explained its authority and discretion to subcategorize within a source 

category under Section 111 in a mercury NSPS for electric utility steam generating units.26 In 

that rule, EPA established five subcategories of boilers based on coal rank and process type.27 In 

doing so, EPA explained that under Section 111 it “* * * has the discretion to ‘distinguish among 

classes, types, and sizes within categories of new sources * * *’ in establishing standards when 

differences between given types of sources within a category lead to corresponding differences in 

the nature of emissions and the technical feasibility of applying emission control techniques.”28 

Thus, for example, in addition to categorizing utility boilers based on coal rank (or fuel input) 

and process type, it has also subcategorized source categories based on facilities’ capacities.29 

EPA’s 2005 mercury NSPS for boilers was vacated by the D.C. Circuit in connection with 

another rulemaking for reasons wholly unrelated to subcategorization.30 Nevertheless, in 

February 2012, EPA further expounded upon its authority to subcategorize under CAA § 111, as 

well as CAA § 112, and consistent with its prior subcategorizations, stated that subcategorization 

is appropriate when the differences among the sources lead to a difference in the nature of 

emissions and the feasibility of applying a control technique.31 In this recent rule, EPA 

determined that continuing to subcategorize utility boilers based on coal rank and process type 

was appropriate.

EPA to promulgate non-uniform standards within a source category is not inconsistent with the remainder of the

In sum, ample authority and precedent exists for EPA to subcategorize NAPs within that source 

category, and to provide non-uniform NSPS for the subcategories. Further, as set forth in TFI’s 

comments, and as discussed in the March 15, 2012, meeting, TFI believes that subcategorization 

of the NAP source category is appropriate given the great variability in conditions at NAPs, 

which, in turn, substantially impacts the technical feasibility of applying emission control 

techniques to meet a uniform standard (particularly when that standard is based on test plants 

that are not representative of the industry).32 

Unlike the test plants discussed in the Nitric Acid NSPS Proposal, many NAPs used NSCR as an 

emission control unit. In Section III of this letter, we described the nature of NSCR and why it is 

an integral part of the NAP, and its operation, particularly in terms of heat balance and energy 

generation for other parts of the NAP. Other NAPs do not face these conditions, limitations, or 

the inability to modify their operations, or their attendant impacts on emissions.33 Existing, nonNSCR NAPs also face similar technical issues related to meeting a uniform standard due to 

design capacity/size, extended absorption use and size, and the lack of multiple emissions 

controls and/or design capabilities that eliminate inefficient operations (such as startup, shut 

down, and maintenance periods), unlike EPA’s test plants.34 

Given the foregoing, TFI continues to recommend that EPA establish NOx standards for three 

subcategories of NAPs: (1) a NOx standard for new NAPs; (2) a NOx standard for existing NAPs 

without NSCR that undergo a modification or reconstruction; and, (3) a NOx standard for 

existing NAPs with NSCR that undergo a modification or reconstruction
