Subject: Revisions to Wisconsin's Ozone State Implementation Plan

Dear Ms. Hedman:

The Wisconsin Department ofNatural Resources (WDNR) submitted a State Implementation Plan (SIP) revision on

November 16,2011 regarding changes to cbs. NR 400,419,421,422,423,439, and 484, Wis. Adm. Code. The

revised rules ensure that reasonably available control technology (RACT) for volatile organic compounds (VaC) is

required in Wisconsin's moderate ozone nonattainment counties consistent with applicable U.S. EPA Control

Techniques Guideline (CTG) documents. As correctly noted by u.S. EPA Region V staff, some ofthe rules

submitted reference sections of ch. NR 440, Standards ofPerfonnance for New Stationary Sources, Wis. Adm. Code.

As such, the purpose ofthis letter is to fonnally request inclusion ofthe referenced sections (NR 440.675, 440~ 686,

and 440.705, Wis. Adm. Code) into Wisconsin's Ozone SIP.

The WDNR has the legal authority under Wisconsin law to adopt and implement these requested SIP revisions.

Section 285.11 (6), Wis. Stats., authorizes the WDNR to develop and revise the SIP for prevention, abatement, and

control of air pollution. The WDNR conducted a public hearing on ch. NR 440, Wis. Adm. Code, on November 21,

2006. A copy ofthe public hearing notice is included as an attachment.

In accordance with the April 6, 2011 McCabe Memo, one paper-copy ofthe SIP revision documents are enclosed. In

addition, an electronic copy ofthese documents is provided as well on an enclosed CD. Ifyou have any questions

regarding this submittal, please feel free to call Joseph Hoch at 608-267-7543 or Ralph Patterson at 608-267-7546.

NOTICE OF PUBLIC HEARING

AM-OS-06

NOTICE IS HEREBY GIVEN that pursuant to SSe 227.11(2)(a), 285.11(1) and 285.27(1)(a), Stats.,

interpreting s. 285.11(1), Stats., the Department of Natural Resources will hold a public hearing on revisions

to ch., NR 440, Wis. Adm. Code, relating to incorporation of revisions and additions to the federal New

Source Performance Standards. Under section 111 of the Clean Air Act, the U.S. Environmental Protection

Agency is required to promulgate regulations establishing standards of performance of new stationary

sources (NSPS). These standards are contained in 40 CFR Part 60. The Department is required, under s.

285.27(1 )(a), Stats., to incorporate these standards into rule, and does so in ch. NR 440. Periodically it is

necessary to amend ch. NR 440 to address changes the EPA makes to existing NSPS and to incorporate

standards promulgated by EPA for new source categories. These proposed reVisions address changes

made by the EPA between July 1994 and April 2005 to general reqUirements which apply to all source

categories, and to the specific standards for 60 individual source categories. Requirements relating to

mercury emission from certain electric steam generating units which EPA promulgated on May 18, 2005

and subsequently amended are not proposed here. Those requirements will be addressed separately in

Natural Resources Board Order No. AM-32-05. Standards for 5 source categories not currently included in

ch. NR 440 are also being proposed.

NOTICE'IS HEREBY FURTHER GIVEN that pursuant to s. 227.114, Stats., it is not anticipated

that the proposed rule will have a substantial economic impact on small businesses. The proposed rules

are substantively identical to rules already in effect at the federal level. Any small businesses currently

subject to the federal reqUirements will not be impacted by incorporation of these requirements into the

Wisconsin Administrative Code. The Department's Small Business RegUlatory Coordinator may be

contacted at SmatlBusiness@dnr.state.wLus or by calling (608) 266-1959.

NOTICE IS HEREBY FURTHER GIVEN that the Department has made a preliminary

determination that this action does not involve significant adverse environmental effects and does not

need an environmental analysis under ch. NR 150, Wis. Adm. Code. However, based on the comments

received, the Department may prepare an environmental analysis before proceeding with the proposal.

This environmental review document would summarize the Department's consideration of the impacts of

the proposal and reasonable alternatives.

NOTICE IS HEREBY FURTHER GIVEN that the hearing will be held on:

November 21, 2006

Tuesday

Room G09, GEF #2 Building, 101 South Webster Street, Madison

at 1:00 p.m.

NOTICE IS HEREBY FURTHER GIVEN that pursuant to the Americans with Disabilities Act,

reasonable accommodations, including the provision of information material in an alternative format, will

be provided for qualified individuals with disabilities upon request. Please call Robert Eckdale at (608)

266-2856 or bye-mail at Robert.Eckdale@dnr.state.wLus with specific information on your request at

equipment for mixing, filtering, blending and storage of the

spinning solutions.

(q) “Synthetic fiber” means any fiber composed partially or

entirely of materials made by chemical synthesis or made partially or entirely from chemically−modified naturally−occurring

materials.

(r) “Viscose process” means the fiber forming process where

cellulose and concentrated caustic soda are reacted to form soda

or alkali cellulose. This reacts with carbon disulfide to form sodium cellulose xanthate which is then dissolved in a solution of

caustic soda. The solution is spun into an acid coagulating bath

after ripening. This precipitates the cellulose in the form of a regenerated cellulose filament.

(3) STANDARD FOR VOLATILE ORGANIC COMPOUNDS. On and

after the date on which the initial performance test required to be

conducted by s. NR 440.08 is completed, no owner or operator

subject to the provisions of this section may cause the discharge

into the atmosphere from any affected facility that produces

acrylic fibers VOC emissions that exceed 10 kg/Mg (20 lb/ton)

solvent feed to the spinning solution preparation system or precipitation bath. VOC emissions from affected facilities that produce both acrylic and nonacrylic fiber types may not exceed 10

kg/Mg (20 lb/ton) solvent feed. VOC emissions from affected

facilities that produce only nonacrylic fiber types may not

exceed 17 kg/Mg (34 lb/ton) solvent feed. Compliance with the

emission limitations is determined on a 6−month rolling average

basis as described in sub. (4).

(4) PERFORMANCE TEST AND COMPLIANCE PROVISIONS. (a)

Section NR 440.08 (6) does not apply to the performance test

procedures required by this section.

(b) Each owner or operator of an affected facility shall determine compliance with the applicable standard in sub. (3) by

determining and recording monthly the VOC emissions per unit

mass solvent feed from each affected facility for the current and

preceding 5 consecutive calendar months and using these values

to calculate the 6−month average emissions. Each calculation is

considered a performance test. The owner or operator of an affected facility shall use the following procedure to determine

VOC emissions for each calendar month:

1. Install, calibrate, maintain, and operate monitoring devices that continuously measure and permanently record for

each calendar month the amount of makeup solvent and solvent

feed. These values shall be used in calculating VOC emissions

according to subd. 2. All monitoring devices, meters and peripheral equipment shall be calibrated and any error recorded. Total

compounded error of the flow measuring and recording devices

may not exceed 1% accuracy over the operating range. As an alternative to measuring solvent feed the owner or operator may:

a. Measure the amount of recovered solvent returned to the

solvent feed storage tanks and use the following equation to determine the amount of solvent feed:

Solvent Feed = Makeup Solvent + Recovered Solvent +

Change in the Amount of Solvent Contained in the Solvent Feed

Holding Tank.

b. Measure and record the amount of polymer introduced

into the affected facility and the solvent−to−polymer ratio of the

spinning solutions and use the following equation to determine

the amount of solvent feed:

Solvent Feed 

n

i1

(Polymer Used)i  (Solvent–to–Polymer Ratio)i

where subscript “i” denotes each particular spinning solution used during the test period; values of “i” vary from one to

the total number of spinning solutions, “n,” used during the calendar month.

2. VOC emissions shall be determined each calendar month

by use of the following equations:

I−N− where DSMM

S

M E W PV

W

= W =

K

DSS S PV

W =

W

SE

S

I −I I =

where all values are for the calendar month only and where:

E is the VOC emissions in kg/Mg (lb/ton) solvent

SV is the measured or calculated volume of solvent feed in

liters (gallons)

SW is the weight of solvent feed in Mg (ton)

MV is the measured volume of makeup solvent in liters (gallons)

MW is the weight of makeup in kg (lb)

N is the allowance for nongaseous losses, 13 kg/Mg (26 lb/

ton) solvent feed to the spinning solution preparation system and

precipitation bath. This value shall be used in all cases unless an

owner or operator demonstrates to the satisfaction of the department that greater nongaseous losses occur at the affected facility.

In this case, the greater value may be substituted in the equation.

SP is the fraction of measured volume that is actual solvent

(excludes water)

D is the density of the solvent in kg/liter (lb/gallon)

K is a conversion factor, 1000 kg/Mg (2,000 lb/ton)

I is the allowance for solvent inventory variation or changes

in the amount of solvent contained in the affected facility, kg/Mg

(lb/ton) solvent feed (may be positive or negative)

IS is the amount of solvent contained in the affected facility

at the beginning of test period, as determined by the owner or

operator, in kg (lb)

IE is the amount of solvent contained in the affected facility

at the close of the test period, as determined by the owner or operator, in kg (lb)

(5) REPORTING REQUIREMENTS. (a) The owner or operator of

an affected facility shall submit a written report to the department

of the following:

1. The results of the initial performance test; and

2. The results of subsequent performance tests that indicate

that VOC emissions exceed the standards in sub. (3). These reports shall be submitted quarterly at 3−month intervals after the

initial performance test. If no exceedances occur during a particular quarter, a report stating this shall be submitted to the department semiannually.

(b) Solvent−spun synthetic fiber producing facilities exempted from these standards in sub. (1) (a) (those producing less

than 500 Mg (551 tons) annually) shall report to the department

within 30 days whenever extruded fiber for the preceding 12 calendar months exceeds 500 Mg (551 tons).

molar composition determination prescribed in subds. 3. and 4.

shall be, except for the situations outlined in subd. 2., prior to the

inlet of any control device, prior to any post−reactor dilution of

the stream with air and prior to any post−reactor introduction of

halogenated compounds into the vent stream. No transverse site

selection method is needed for vents smaller than 10 centimeters

(4 inches) in diameter.

2. If any gas stream other than the air oxidation vent stream

from the affected facility is normally conducted through the final

recovery device:

(g) Each owner or operator of an affected facility seeking to

comply with sub. (1) (c) 4. or (3) (c) shall recalculate the TRE

index value for that affected facility whenever process changes

are made. Examples of process changes include changes in production capacity, feedstock type or catalyst type or whenever

there is replacement, removal or addition of recovery equipment. The TRE index value shall be recalculated based on test

data or on best engineering estimates of the effects of the change

to the recovery system.

1. Where the recalculated TRE index value is less than or

equal to 1.0, the owner or operator shall notify the department

within one week of the recalculation and shall conduct a performance test according to the methods and procedures required by

this subsection in order to determine compliance with sub. (3)

(a). Performance tests shall be conducted as soon as possible after the process change but no later than 180 days from the time

of the process change.

2. Where the initial TRE index value is greater than 8.0 and

the recalculated TRE index value is less than or equal to 8.0 but

greater than 1.0, the owner or operator shall conduct a performance test in accordance with s. NR 440.08 and this subsection

and shall comply with subs. (4) and (6) and this subsection. Performance tests shall be conducted as soon as possible after the

process change but no later than 180 days from the time of the

process change.

NR 440.71 Magnetic tape coating facilities.

(1) APPLICABILITY AND DESIGNATION OF AFFECTED FACILITY. (a)

The affected facilities to which the provisions of this section apply are:

1. Each coating operation; and

2. Each piece of coating mix preparation equipment.

(b) Any new coating operation that utilizes less than 38 m3

of solvent or any modified or reconstructed coating operation

that utilizes less than 370 m3 of solvent for the manufacture of

magnetic tape per calendar year is subject only to the requirements of subs. (5) (a) and (8) (b) and(c). If the amount of solvent

utilized for the manufacture of magnetic tape equals or exceeds

these amounts in any calendar year, the facility is subject to sub.

(3) and all other paragraphs of this section. Once a facility has become subject to sub. (3) and all other paragraphs of this section,

it shall remain subject to those requirements regardless of

changes in annual solvent utilization.

(c) This section applies to any affected facility for which construction, modification or reconstruction begins after January

22, 1986.

(2) DEFINITIONS, SYMBOLS AND CROSS REFERENCE TABLES.

(a) All terms used in this section that are not defined as follows

have the meaning given to them in s. NR 440.02.

1. “Base film” means the substrate that is coated to produce

magnetic tape.

2. “Capture system” means any device or combination of

devices that contains or collects an airborne pollutant and directs

it into a duct.

3. “Coating applicator” means any apparatus used to apply

a coating to a continuous base film.

4. “Coating mix preparation equipment” means all mills,

mixers, holding tanks, polishing tanks and other equipment used

in the preparation of the magnetic coating formulation but does

not include those mills that do not emit VOC because they are

closed, sealed and operated under pressure.

5. “Coating operation” means any coating applicator, flashoff area and drying oven located between a base film unwind station and a base film rewind station that coat a continuous base

film to produce magnetic tape.

6. “Common emission control device” means a control device controlling emissions from the coating operation as well as

from another emission source within the plant.

7. “Concurrent” means construction of a control device is

commenced or completed within the period beginning 6 months

prior to the date construction of affected coating mix preparation

equipment commences and ending 2 years after the date construction of affected coating mix preparation equipment is completed.

8. “Control device” means any apparatus that reduces the

quantity of a pollutant emitted to the air.

9. “Cover” means, with respect to coating mix preparation

equipment, a device that lies over the equipment opening to prevent VOC from escaping and that meets the requirements found

in sub. (3) (e) 1. to 5.

10. “Drying oven” means a chamber in which heat is used

to bake, cure, polymerize or dry a surface coating.

11. “Equivalent diameter” means 4 times the area of an

opening divided by its perimeter.

12. “Flashoff area” means the portion of a coating operation

between the coating applicator and the drying oven where solvent begins to evaporate from the coated base film.

13. “Magnetic tape” means any flexible substrate that is covered on one or both sides with a coating containing magnetic particles and that is used for audio or video recording or information

storage.

14. “Natural draft opening” means any opening in a room,

building or total enclosure that remains open during operation of

the facility and that is not connected to a duct in which a fan is

installed. The rate and direction of the natural draft across such

an opening is a consequence of the difference in pressures on either side of the wall containing the opening.

15. “Nominal 1−month period” means a calendar month or,

if established prior to the performance test, a similar monthly

time period, for example, 30−day month or accounting month.

16. “Temporary enclosure” means a total enclosure that is

constructed for the sole purpose of measuring the fugitive emissions from an affected facility. A temporary enclosure shall be

constructed and ventilated, through stacks suitable for testing, so

that it has minimal impact on the performance of the permanent

capture system. A temporary enclosure will be assumed to

achieve total capture of fugitive VOC emissions if it conforms

to the requirements found in sub. (4) (b) 5. a. and if all natural

draft openings are at least 4 duct or hood equivalent diameters

away from each exhaust duct or hood. Alternatively, the owner

or operator may apply to the administrator for approval of a temporary enclosure on a case−by−case basis.

17. “Total enclosure” means a structure that is constructed

around a source of emissions so that all VOC emissions are collected and exhausted through a stack or duct. With a total enclosure, there will be no fugitive emissions, only stack emissions.

The only openings in a total enclosure are forced makeup air and

exhaust ducts and any natural draft openings such as those that

allow raw materials to enter and exit the enclosure for processing. All access doors or windows are closed during routine operation of the enclosed source. Brief, occasional openings of

such doors or windows to accommodate process equipment adjustments are acceptable, but, if such openings are routine or if

an access door remains open during the entire operation, the access door shall be considered a natural draft opening. The average inward face velocity across the natural draft openings of the

enclosure shall be calculated including the area of such access

doors. The drying oven itself may be part of the total enclosure.

A permanent enclosure that meets the requirements found in sub.

(4) (b) 5. a. is assumed to be a total enclosure. The owner or operator of a permanent enclosure that does not meet the requirements may apply to the department for approval of the enclosure

as a total enclosure on a case−by−case basis. Such approval shall

be granted upon a demonstration to the satisfaction of the department that all VOC emissions are contained and vented to the

control device.

18. “Utilize” refers to the use of solvent that is delivered to

coating mix preparation equipment for the purpose of formulating coatings to be applied on an affected coating operation and

any other solvent, for example, dilution solvent, that is added at

any point in the manufacturing process.

20. “Volatile organic compounds” or ‘VOC‘ means any organic compounds that participate in atmospheric photochemical
