organized as follows: 

I. Background 

II. Request for AMEL 

III. AMEL for the Rohm and Haas Chemicals 

LLC facility 

IV. Request for Comments 

I. Background 

Rohm and Haas is requesting an 

AMEL for the Standards of Performance 

for Volatile Organic Liquid Storage 

Vessels, 40 CFR part 60, subpart Kb (40 

CFR 60.112b), that would apply to a 

proposed new vinyl acetate bulk storage 

tank to be used at its chemical plant in 

Kankakee, Illinois. In this Federal 

Register document, the EPA is soliciting 

comment on all aspects of this AMEL 

request, including the corresponding 

operating conditions that would 

demonstrate that the requested AMEL 

would achieve a reduction in emissions 

of volatile organic compounds (VOC) at 

least equivalent to the reduction in 

emissions required by the new source 

performance standards (NSPS) at 40 

CFR 60.112b. The AMEL request states 

that a new storage tank will be installed 

at the site to replace the existing vinyl 

acetate monomer (VAM) (CAS 108–05– 

4) tank (TK–72). Such tank functions as 

a buffer for the facility’s manufacturing 

needs between bulk deliveries of VAM. 

The facility receives VAM 

predominantly by railcar, but 

occasionally some VAM is supplied via 

tank truck. Due to the facility’s demand 

for VAM, the tank experiences a 

significant number of turnovers per 

year. 

Because the new storage tank will be 

used to store VAM, a volatile organic 

liquid as defined at 40 CFR 60.111b, it 

is subject to NSPS subpart Kb. Rohm 

and Haas is submitting this AMEL 

request because the proposed tank 

design does not contain either an 

external or internal floating roof or a 

closed vent system and control device 

that are specified by 40 CFR 60.112b; 

rather, it is designed to reduce 

emissions through vapor balancing and 

pressure containment. Rohm and Haas 

states that breathing losses will not 

occur from the proposed new tank 

because there are no vents and the tank 

can withstand pressures up to 9 pounds 

per square inch gauge (psig) before 

activation of a pressure relief device 

(PRD). Rohm and Haas further states 

that the proposed system will control 

emissions from working losses by 

complying with the requirements 

associated with the use of a vapor 

balancing system in the National 

Emission Standards for Organic 

Hazardous Air Pollutants (NESHAP) 

from the Synthetic Organic Chemical 

Manufacturing Industry for Process 

Vents, Storage Vessels, Transfer 

Operations, and Wastewater, 40 CFR 

part 63, subpart G.1

The VOC standards at 40 CFR 60.112b 

were established as work practice 

standards pursuant to CAA section 

111(h)(1). For standards established 

according to that provision, CAA 

section 111(h)(3) allows the EPA to

2As explained in the preamble to the proposed 

NSPS subpart Kb, equivalence ‘‘could be 

demonstrated by a number of methods including: 

(1) An actual emissions test that uses a full size or 

scale-model storage vessel that accurately collects 

and measures all VOC emissions from the storage 

vessel, or (2) an engineering evaluation as approved 

by the Administrator.’’ (Emphasis added). 49 FR 

29698, 29706 (July 23, 1984). 

permit the use of an AMEL by a source 

if, after notice and opportunity for 

public hearing, it is established to the 

Administrator’s satisfaction that such 

AMEL will achieve emissions 

reductions at least equivalent to the 

reductions required under the 

applicable CAA section 111(h)(1) 

standards. NSPS subpart Kb also 

includes specific regulatory provisions 

(i.e., 40 CFR 114b) allowing sources to 

request an AMEL for the VOC standards 

at 40 CFR 112b. 

Rohm and Haas included in its AMEL 

application information to demonstrate 

that the proposed bulk storage tank, 

through its vapor balancing system and 

pressure containment design, will 

achieve a reduction in emissions at least 

equivalent to the reduction in emissions 

achieved by the VOC standards at 40 

CFR 60.112b. Rohm and Haas’s AMEL 

request was submitted on June 17, 2020. 

For Rohm and Haas’s AMEL request, 

including any supporting materials 

Rohm and Haas submitted, see Docket 

ID No. EPA–HQ–OAR–2020–0599. 

II. Request for AMEL 

Pursuant to 40 CFR 60.114b, Rohm 

and Haas is seeking an AMEL for the 

VOC standards set forth at 40 CFR 

60.112b for a proposed bulk storage tank 

to be used at its chemical plant in 

Kankakee, Illinois. Rohm and Haas’s 

application includes an engineering 

evaluation to support its request, as 

required by 40 CFR 60.114b(c).2 We, 

therefore, deem this AMEL application 

by Rohm and Haas to be complete. 

Rohm and Haas submitted this AMEL 

request because the proposed tank 

design does not contain either an 

external or internal floating roof or a 

closed vent system and control device 

that are specified by 40 CFR 60.112b. 

Rohm and Haas is proposing an 

alternative tank design that will 

eliminate breathing losses by storing 

material in a pressure tank and control 

working losses using vapor balancing. 

The information provided by Rohm 

and Haas states that the proposed new 

tank is an American Petroleum Institute 

(API)–620, 160,000 gallon 

(approximately 600 cubic meter) fixedroof storage tank used for the storage of 

VAM. An API–620 specification tank is 

designed to contain pressures up to 15 

psig. According to Rohm and Haas, 

breathing losses will not occur because 

there are no vents, and the tank can 

withstand pressures up to 9 psig before 

activation of a PRD. Rohm and Haas’s 

engineering evaluation indicates the 

tank is not expected to exceed these 

pressures. The published vapor pressure 

of VAM is 1.72 pounds per square inch 

(psi) (89.1 millimeters of mercury) at 68 

degrees Fahrenheit (°F); however, the 

EPA defines the maximum true vapor 

pressure (MTVP) as the vapor pressure 

of a specific material at the maximum 

average monthly temperature, which is 

74.7 °F and occurs during the month of 

July in the Kankakee locale. At the 

specified maximum temperature, using 

the Antoine equation and appropriate 

coefficients, the MTVP of vinyl acetate 

was estimated to be 2.09 psi, which is 

well below the 9 psig rupture disk and 

PRD settings for the proposed tank. 

Therefore, PRDs will be designed to 

open only in emergency instances (i.e., 

external fire or uncontrolled 

polymerization). 

The PRDs will consist of two pressure 

relief assemblies. The primary assembly 

will include in series a rupture disk, a 

pressure indicator, and a pressure relief 

valve (PRV). The rupture disk and PRV 

will both be set at 9 psig. The purpose 

of this assembly is to provide early 

controlled remediation in case of fire/ 

polymerization/over-pressurization. 

Because the PRV is downstream of the 

rupture disk, the design will allow the 

assembly to return to its closed position 

once the pressure release event ends. 

The secondary pressure relief assembly 

will consist of a rupture disk set at 13 

psig, followed by a pressure indicator. 

This assembly is designed to contain 

extreme fire/polymerization in the event 

the first assembly is unable to do so. In 

such event, the rupture disk will vent to 

protect against vessel rupture. 

To demonstrate that the PRV does not 

open, the tank vapor space pressure and 

the space between the rupture disk and 

PRV will be continuously monitored for 

pressure and recorded. If a release 

occurs, a new rupture disk will be 

installed, and the corresponding PRV 

will be reseated properly. This PRV will 

be checked quarterly to ensure the PRV 

is seated properly using EPA Method 21 

following 40 CFR 63.119(g)(5)(i), part of 

the vapor balancing provisions in 

NESHAP subpart G (40 CFR 63.119(g)). 

In the event that a PRV opens, this 

would qualify as an excess emission 

event and must be reported on the 

semiannual compliance report. If 

designed and operated as described 

above, there will not be any emission 

events, therefore, this alternative is 

equivalent with the standard. 

No PRD on the storage tank, railcar, or 

tank truck is expected to open during 

loading or as a result of diurnal 

temperature changes (breathing losses). 

During filling of the tank, any displaced 

vapors will be collected and routed 

through the vapor balancing line. There 

are no PRDs associated with the vapor 

balancing line itself, and the PRDs on 

the railcar are set at 165 psig and tank 

trucks are set between 25 to 50 psig to 

prevent an opening of a PRD while the 

vessel is being unloaded. 

The tank will also be equipped with 

a vacuum relief system that will be used 

when VAM is transferred to the process 

area, and both the vacuum relief system 

and a vapor balance system will be used 

when VAM is added to the tank. The 

vacuum relief system only serves to 

allow ambient air into the tank’s head 

space to equalize pressure decreases as 

material is removed. The vapor balance 

system operation collects and contains 

vapors discharged during tank filling 

operations. 

In its request, Rohm and Haas states 

that the proposed tank would comply 

with the vapor balancing requirements 

in NESHAP subpart G, 40 CFR 63.119(g) 

to confirm proper vapor balancing. 

The facility unloads VAM from tank 

trucks or railcars, which are connected 

to the tank system’s vapor balance 

system. The Kankakee facility’s bulk 

unloading Standard Operating 

Procedure requires that each U.S. 

Department of Transportation (DOT)- 

specification tank truck or railcar 

containing vinyl acetate be inspected to 

verify that its DOT qualification 

inspections and tests are current. VAM 

will be unloaded only from tank trucks 

or railcars which are connected to the 

tank system’s vapor balance system. 

The site will require that railcars and 

tank trucks that deliver VAM will be 

reloaded or cleaned only at facilities 

which utilize the control techniques 

specified at 40 CFR 63.119(g)(6)(i) or (ii) 

of NESHAP subpart G. The site will 

mandate that each railcar or tank truck 

is connected to a closed-vent system 

with a control device that reduces inlet 

emissions of HAP by 95 percent by 

weight or greater. 

The Kankakee facility will request, 

maintain, and submit to the 

Administrator a written certification 

from the VAM supplier that each 

supplier’s current reloading or cleaning 

facility meets the above requirements. If 

the supplier(s) of the VAM changes in 

the future, the Kankakee facility will 

obtain a written certification that the 

new supplier(s) meet these 

requirements. 

Rohm and Haas believes that this 

tank, as designed and operated, will 


jbell on DSKJLSW7X2PROD with NOTICES
8622 Federal Register / Vol. 86, No. 24 / Monday, February 8, 2021 / Notices 

result in a reduction in emissions 

equivalent to or better than the amount 

achieved by the VOC standards set forth 

in 40 CFR 60.112b of NSPS subpart Kb. 

Rohm and Haas, therefore, asks that the 

EPA approve this AMEL request. 

III. AMEL for the Rohm and Haas 

Chemicals LLC Facility 

Based upon our review of the AMEL 

request, we believe that, by complying 

with the operating conditions specified 

below, the proposed new tank at Dow’s 

Rohm and Haas Chemicals LLC facility 

will achieve emission reductions at least 

equivalent to reduction in emissions 

required by NSPS subpart Kb, 40 CFR 

60.112b. We are seeking the public’s 

input on this request. Specifically, the 

EPA seeks the public’s input on the 

conditions specified in this document in 

the following paragraphs. 

(1) No PRD on the storage tank, or on 

the railcar or tank truck, shall open 

during loading or as a result of diurnal 

temperature changes (breathing losses). 

(2) Both PRDs on the storage tank 

must be set to release at no less than 9 

psig at all times. Any release from a PRD 

as indicated by pressure reading greater 

than 9 psig is an excess emissions event. 

To demonstrate that the PRD does not 

open, the tank vapor space pressure and 

the space between the rupture disk and 

PRD will be continuously monitored for 

pressure and recorded. If a release 

occurs, the tank must follow 40 CFR 

63.165(d)(2). 

(3) Each of the PRDs and components 

of the vapor collection system on the 

tank must be monitored on a quarterly 

basis, using EPA Method 21. An 

instrument reading of 500 parts per 

million by volume or greater is an 

excess emissions event. 

(4) VAM must be transferred from 

either railcars or truck trailers via 

welded steel piping into the new bulk 

storage tank. The tank must be equipped 

with a welded steel vapor balance line 

that returns displaced vinyl acetate 

vapors from the headspace within the 

tank to the railcar or tank truck during 

tank filling operations. The vapor 

balance line must be hard piped from 

the tank, crossing a pipe bridge, before 

terminating at the off-loading station. 

The tank vapor balance line must not 

contain any PRDs or release points. 

Displaced vapors must be transferred to 

a vapor return fitting on the offloading 

bulk vehicle through a hose from the 

offloading station. Both the transfer 

hoses and the vapor balance return line 

must incorporate dry-disconnect fittings 

to prevent vapor discharge to the 

atmosphere when the line is not 

connected. Tank trucks and railcars 

must have a current certification in 

accordance with the DOT pressure test 

requirements of 49 CFR part 180 for 

tank trucks and 49 CFR 173.31 for 

railcars. Railcars, tank trucks, or barges 

that deliver VAM to a storage tank must 

be reloaded or cleaned at a facility that 

utilizes the control techniques specified 

in paragraph (4)(a) or (b). 

(a) The railcar, tank truck, or barge 

must be connected to a closed-vent 

system with a control device that 

reduces inlet emissions of VAM by 95 

percent by weight or greater. 

(b) A vapor balancing system 

designed and operated to collect organic 

VAM vapor displaced from the tank 

truck or railcar during reloading must be 

used to route the collected HAP vapor 

to the storage tank from which the 

liquid being transferred originated. 

(5) Rohm and Haas must submit to the 

Administrator a written certification 

that the reloading or cleaning facility 

meets the requirements of paragraph 4; 

and the requirements for closed vent 

system and control device specified at 

40 CFR 63.119 through 63.123. The 

notification and reporting requirements 

at 40 CFR 63.122 do not apply to the 

owner or operator of the offsite cleaning 

or reloading facility. 

(6) Recordkeeping requirements. 

(a) The facility must keep a record of 

the equipment to be used and the 

procedures to be followed when 

reloading the railcar, tank truck, or 

barge and displacing vapors to the 

storage tank from which the liquid 

originates, as well as a record of all 

components of the PRDs, including 

PRVs and rupture disks. 

(b) Records must be kept as long as 

the storage vessel is in operation. 

(7) Reporting requirements. The 

facility must submit excess emissions 

and monitoring systems performance 

reports to the Administrator 

semiannually. All reports must be 

postmarked by the 30th day following 

the end of each 6-month period. Written 

reports of excess emissions must 

include the following information: 

(a) The date and time of 

commencement and completion of each 

time period of excess emissions. The 

process operating time during the 

reporting period. 

(b) The date and time identifying each 

period during which the continuous 

monitoring system was inoperative 

except for zero and span checks and the 

nature of the system repairs or 

adjustments. 

(c) The report must include a list of 

the affected sources or equipment, an 

estimate of the volume of VAM emitted, 

and a description of the method used to 

estimate the emissions. 

(d) When the continuous pressure 

monitoring systems have not been 

inoperative, repaired, or adjusted, such 

information shall be stated in the report. 

IV. Request for Comments 

We solicit comments on all aspects of 

Rohm and Haas’s requests for approval 

of an AMEL for these new requirements 

to be used to comply with the 

applicable standards. We specifically 

seek comment regarding whether or not 

the operating requirements listed in 

section III above will achieve emission 

reductions at least equivalent to 

emissions being controlled by 

complying with the applicable 

requirements in the 40 CFR part 60, 

subpart Kb, Standards of Performance 

for Volatile Organic Liquid Storage 

Vessels requirements in 40 CFR 

60.112b.
