Summary and Recommendations

Proposed amendments to Rules 15A NCAC 02D .0902, Applicability; 15A NCAC 02D .0903 Recordkeeping: Reporting: Monitoring; 15A NCAC 02D .0909, Compliance Schedules for Sources in Nonattainment Areas; 15A NCAC 02 D .0951 RACT For Sources of Volatile Organic Compounds; 15A NCAC 02D .0961, Offset Lithographi c Printing and Letterpress Printing; 15A NCAC 02D .0962, Industrial Cl eaning Solvents; and 15A NCAC 02Q .0102 Activities Exempted From Permit Requirements.

BACKGROUND AND SUMMARY
In comments on North Carolina’s redesignation demonstration and maintenance plan for the North Carolina portion of the Charlotte-Gaston ia-Rock Hill, NC-SC 199 7 8-hour Ozone National Ambient Air Quality Standard (NAAQS) Nonattainme nt Area, USEPA identified the need for an adjustment of applicability of the state’s Reasonably Available Control Technology (RACT) rules. Section 182(b)(2) of the Clean Air Act (CAA) requires RACT for all sources addressed by Control Technique Guidelines (CTGs) in areas classified moderate and above. The current RACT rules’ applicability is structured such that the RACT requirement for sources in CTG categories applies to major sources. For a mode rate nonattainment area major sources are those with emissions of 100 tons of volatile organic compounds or more per year.
Applicability changes are proposed to address the issue identified by EPA, and when the changes are adopted it is expected that EPA will appr ove the re-designation request and maintenance plan. Once the area has been re-designated, the ru le changes would apply only under the scenario that the area later violates the 1997 8-hour ozone standard and, based on technical analysis, if implementation of the rules would assist in bringing the area back into attainment as part of required contingency measures.
A public hearing was held by the North Caroli na Department of Environment and Natural Resources, Division of Air Qu ality on January 15, 2013 to ta ke public comments on proposed amendments to the Volatile Organic Com pound RACT rules in 15A NCAC 02D Section .0900 to revise applicability requirements to comply with Section 182(b)(2) of the Clean Air Act; to revise associated compliance schedules; to prov ide flexibility to comply via category specific rules or site specific alternativ es; and to amend printing related and industrial solvent cleaning RACT rules in response to requests for language cl arifications and flexibil ities consistent with underlying USEPA Control Technique Guidelines. Mr. Benne C. Hutson of the Environmental Management Commission (EMC) was appointed and acted as the hear ing officer for this hearing.
15A NCAC 02D .0902, Applicability, is proposed for amendments: (1) to extend RACT requirements to apply to all sour ces addressed by CTGs in the Charlotte-Gastonia nonattainment area and also to clarify the provisi on that certain rules continue to apply stat ewide; (2) to define the range of applicable facilities in accordance with Section 182(b)(2) of the Clean Air Act and allow for transition of the requirements to contingency measures upon re-designation of the area

consistent with EPA procedures; (3 ) to address the contingency plan in the event that a violation of the 1997 ozone standard occurs and specify measures required by the Clean Air Act (CAA) under that scenario; (4) to provide some flexibility for alterna tive compliance options that is specified by the amendment to th e rule .0961(b); and (5) to clarif y the exemption of laboratories that emit less than 800 pounds of VOC per month from provisions of the Section.
15A NCAC 02D .0903, Recordkeeping: Reporting: Monitoring, is proposed for amendments to reflect incorporation of the monthly reco rdkeeping alternative provided in 02D .0961 for consistency with the CTG and in response to industry representative’s comments.
15A NCAC 02D .0909, Compliance Schedules fo r Sources in Nonattainment Areas, is proposed for amendments: (1) to define the status of the nonattainment area in accordance with the current 8-Hour Ozone classifications for th e 1997 standard; (2) to delete as unnecessary provisions that duplicate CTG recommendations on VOC content limits already incorporated into the rule; (3) to allow two years period for compliance achievement if low solvent coating technology is to be used; (4) to establish a schedu le for the newly affected facilities to comply with the RACT requirements via use of solv ent coating technology or via add on control.
15A NCAC 02D .0951, RACT for Sources of Volatile Organic Compounds, is proposed for amendments to give affected facilities a choice whether to apply the RACT requirements defined in .0900 Section rules or choose RACT requirement s demonstrated to the Director and EPA to advance attainment.
15A NCAC 02D .0961, Offset Lithographic Pr inting and Letterpress Printing, is proposed for amendments to comply w ith RACT requirements for VOC emissions from heatset inks, fountain solutions, and cleaning ma terials used in offset lithographic printing operations and for VOC emissions from heatset inks us ed in letterpress printing operations.
15A NCAC 02D .0962, Industrial Cleaning Solvents, is proposed for amendments to exempt cleaning solvent emissions from RACT applicabili ty for resin, coating, ink, and adhesive mixing, molding, and application equipm ent cleaning of coating, ink, and adhesive manufacturing.
15A NCAC 02Q .0102, Activities Exempt ed from Permit Requirements, is proposed for amendment to update a cross reference.

PUBLIC COMMENTS AND RESPONSES THERETO

Comment: Mr. David Darling, P.E., Seni or Director, Environmental Affairs, American Coatings Association (ACA), expresses ACA’s support fo r the proposed amendments to 15A NCAC 02D .0962,Industrial Cleaning Solvents, since these am endments will allow effective cleaning of process equipment at coatings, ink, and adhesive manufacturing operation s. He also indicates that these amendments are consistent with the EPA Industrial Solven t Cleaning CTG (and the Bay Area Air Quality Management District rules on which the EPA Industrial Solvent Cleaning CTG was based.)

### I-3

Response: The proposed amendments to 02D . 0962 are based on understanding that cleaning coating, ink and adhesive manuf acturing equipment is very important since incomplete cleaning of process equipment and tanks can cause cro ss contamination of manu factured product and negatively impact product quality and could resu lt in an off specifica tion product that would need to be disposed of. No change to the propos ed rule is required in response to this comment.

Comment: Mr. Jeff Stoudt, President, The Printing Indus try of the Carolinas (PICA), notes that Paragraph 15A NCAC 02D .0961(f) is not consistent with the CTG in that it sets the limit for add-on controls based on VOC emissions and th e CTG was very specific in setting the limit based on ink oil emissions from the ink. Mr. Stoudt requests th at NCDAQ consider a clarification in Subparagraph NCAC 02D .0961(f) and (f)(1) to specify materials used as the basis for an enforceable limitation to keep i ndividual heatset press below 25 tons per year potential to emit volatile organi c compounds threshold. This clar ification can be achieved by deleting “volatile organic compound” and replaci ng it with “petroleum ink oil” to make it consistent with the CTG as the CTG specified that the 25 tons per year limit is based on petroleum ink oil and not the generic volatile compound.
Response: The EPA noted on page 14 of the CTG, “We also recommend applying the above recommended levels of control to individual heatset web lette rpress printing presses with potential to emit from the dryer, prior to controls, of at least 25 tpy of VOC (petroleum ink oil)

. We recommend providing printers with the option of using an enforceable limitation on potential emissions to keep an individual heatset press be low this 25 tpy potential to emit threshold. This equates to using inks and coatings which contain less than 31.25 tpy VOC (petroleum ink oil) because of the 20 percent ink oil retention” where “the above recommended levels of control” means, “the recommended level of control for VO C emissions from heatset dryers is 90 percent control efficiency for a control device whose first installation date was prior to the effective date of a State RACT rule issued after the date of this CTG. The recommended level of control for VOC emissions from heatset dryers is 95 percent control efficiency for a control device whose first installation date was on or after the effective date of a State RACT rule issued after the date of this CTG,” as described in the Offset and Lithographic Printing CTG, on page 13.
For consistency with the CTG recommendations , the language of Paragraph 15A NCAC 02D .0961(f)(1) is revised as follows: “...use an enforceable limitation on potential emi ssions to keep individua l heatset press below 25 tons per year potential to emit volatile organic compounds (petroleum ink oil) threshold, which can be achieved by using inks and coatings that contain less than 31.25 to ns per year volatile organic compound (petroleum ink oil) where 20 percent retention f actor of petroleum ink oil applies, or by using other methods established by permit conditions”.

Comment: Mr. Jeff Stoudt, President, The Printing Indus try of the Carolina s (PICA), indicates that PICA requests that NCDAQ de lete the phrase “for web offset lithographic printing or letter press printing operations” in S ubparagraph (f)(2) as it is redundant with Subparagraph (f) which also contains the same statement.
Response: The language of Subparagraph (f)(2) is revised as requested by PICA.

### I-4

Comment: Mr. Jeff Stoudt, President, The Printing I ndustry of the Carolinas (PICA), requests that NCDAQ revise the effective date of July 1, 2010 contained in 02D .0961 subparagraphs (f)(2)(A) and (f)(2)(B) to reflect the final date of this ru lemaking as the previous rulemaking was not approved by EPA so there is no concern regarding backsliding.
Response: The date delineating the level of applicab le control requirements in Subparagraphs (f)(2)(A) and (f)(2)(B) has been clarified for facilities with potent ial to emit less than 100 tons of VOC per year and reflects the anticipated eff ective date of the rule amendments, May 1, 2013, consistent with the recommendations in the CTG regarding timing of these requirements.

Comment: Mr. Jeff Stoudt, President, The Printing I ndustry of the Carolinas (PICA), requests that NCDAQ revise the provisions " 

### No more than 110 gallons per year of cleaning materials that do not meet the requirements of Subparagraph (1) or (2) of this Paragraph shall be used during any twelve consecutive months " contained in Paragraph 15A NCAC 02D .0961 (k) in such a way that it would have a (3) placed in front of it so that it is clear th at it is Subparagraph 15A NCAC 02D .0961(k)(3).
Response: For clarity , the rule text has been revised by placing a (3) in front of the third provision.

Comment: Mr. Jeff Stoudt, President, Th e Printing Industry of the Ca rolinas (PICA), noted that the proposed rule 15A NCAC 02D .0961 does not provide a material use altern ative for facilities to determine applicability. Mr. Stoudt proposed that a ne w Subparagraph 15A NCAC 02D .0961(n) be added to lay out requirements for a faci lity to make a determin ation that it is not subject to this rule.
Response: In order to provide sources maximum flex ibility to address their site specific configuration and product usage needs on a case by case basis, North Carolina air quality rules typically do not impose prescriptive emissions calculation procedur es and requirements on sources below applicability thresholds. The rule s contain the EPA recomm ended 15 lb/day actual emissions of VOC before consideration of contro ls, and an equivalent level of 3 tons per 12- month rolling period was proposed to be adde d for the applicability criterion to provide additional flexibility to use monthly VOC us age records for applicability and compliance purposes and thus reduce recordkeeping burden. DAQ regional and central office permitting staff can assist with calculating emissions for applicab ility determinations. Additionally, the affected facility or the industry representative may cont act the DENR Environmental Assistance Center to receive free, non-regulatory technical assistan ce and guidance through regulatory, permitting and compliance processes as well as help in reducing overall enviro nmental impacts. The Center serves as an additional point of contact for our customers and serves as a liaison between the customer and regulatory agencies to help improve customer satisfaction. The suggested Paragraph (n) was not included in the proposed rule amendments and is not proposed to be added to the final amendments.

Comment: Ms. Marcia Y. Kinter, Vice Presiden t-Government & Business Information, Specialty Graphic Imaging Association (SGIA) , noted that Appendix C, Summary of NAICS Codes for nonattainment faciliti es in the Industrial Cleaning Solvent CTG, does not identify

### I-5

digital printing facilities (NAICS 323115) as mee ting the applicability requirements. Further, Ms. Kinter indicated the Bay Ar ea Air Quality Management Distri ct in its recently adopted revisions to their graphic arts rule, Regulation 8, Rule 20, exempt ed digital printing operations and presses from all VOC control requirements, including those asso ciated with cleaning solvents. Ms. Kinter also indi cated that the US EPA did not consider the impact of CTG for Industrial Cleaning Solvents on new and emerging industry se ctors and it did not address emerging industry sectors. Finally, Ms. Ki nter added that following these CTG recommendations, the NC rules did not include digital printing in thei r air pollution control standards. Nevertheless, the Bay Area Air Quality Management Di strict in its recently adopted revisions to their graphic arts rule, Regulation 8, Rule 20, exempt ed digital printing operations and presses from all VOC control requirements, including those asso ciated with cleaning solvents.
Due to above mentioned facts, SGIA respectfu lly requests that the DAQ amend its definition of Graphic Arts operations as found in 15 NCAC 02Q .0803 to include both screen printing and digital imaging operations as follows, "Graphic arts operation" means the a pplication of inks to form words, designs, or pictures to a substrate, usually by a series of application rolls each with only partial coverage and usually us ing letterpress, offset lithography, screen printing, digital imaging technologies, rotogravure, or flexograp hic process”, and on the basis of the fact that graphic arts operations are alrea dy exempted from the permit require ments in the current rule 2Q .0102, Ms. Kinter also recommends that digital operations be ex empted from state’s proposed regulations for cleaning solvents as part of th e amended "Graphic arts operation" definition.
Response: EPA did not consider or address emerging industry sectors, such as digital printing, in development of its CTG for Industrial Cleaning Solvents. As a result, such sectors are not subject to the requirements of the CTG. The NC rules did not include digital printing in the air pollution control standards either. 

### The Rule 02Q .0803, Coating, Solvent Cl eaning, Graphic Arts Operations, where “graphic arts operations” is defined is not a part of this amendm ents package and cannot be amended for clarity with this rulemaking process. However, the definition of “graphic arts operations” can be considered for amendment to address SGIA’s concern through a separate rulemaking action in the future.

Comment: Mr. R. Scott Davis, Ch ief Air Planning Branch, USEPA, Region 4, noted that USEPA, Region 4 completed its review of the prehearing submittal and offers no comments at this time.
Response: No changes to the rules are require d as a response to this comment.

SUMMARY OF COMMENTS AND RESPONSES
15A NCAC 02D .0961, Offset Lithographi c Printing and Lett erpress Printing Comments Response Concerns are expressed that Subparagraph 15A NCAC 02D .0961 (f) is not consistent with the CTG in that it sets the limit for add-on controls based on VOC emissions and the CTG was very The language of paragraph 15A NCAC 02D .0961(f)(1) is revised as recommended in the CTG to clarify VOC emissions are based on petroleum ink oil.

specific in setting the limit based on ink oil emissions from the ink. Request is made that NCDAQ delete the phrase “for web offset lithogra phic printing or letter press printing operations” in subparagraph (f)(2) as it is redundant with subparagraph (f) which also contains the same language. The language of subparagraph (f)(2) is revised as requested.

Request is made that the effective date of July 1, 2010 in the Subparagraphs (f)(2)(A) and (f)(2)(B) be revised to reflect the final date of this rulemaking as the previous rulemaking was not approved by EPA so there is no concern regarding backsliding. The date delineating level of applicable control requirements in Subparagraphs (f)(2)(A) and (f)(2)(B) has been clarified for facilities with potential to emit less than 100 tons of VOC per year to reflect the anticipated effective date of these amendments, May 1, 2013.
Revise the provisions of Paragraph 15A NCAC 02D .0961(k) in such a way that it would have three subparagraphs instead of two. Paragraph 15A NCAC 02D .0961(k) is revised by numbering the third provision as subparagraph (3). Concerns are expressed that the proposed rule 15A NCAC 02D .0961 does not provide a material use alternative fo r facilities to determine applicability and anew Subparagraph 15A NCAC 02D .0961(n) is proposed to lay out requirements for a facility to make a determination that it is not subject to this rule. To allow maximum flexibility for sources, prescriptive requirements for calculating emissions to determine applicability are typically not imposed in NC air rules. Suggested language is not included. No change.

15A NCAC 02D .0962, Industrial Cleaning Solvents Comments Response Support is expressed for proposed amendments to 15A NCAC 02D .0962, Industrial Cleaning Solvents, since these amendments will allow effective cleaning of process equipment at coatings, ink, and adhesive manufacturing operations. These amendments are consistent with the EPA Industrial Solvent Cleaning Control Technique Guideline (CTG) (and the Bay Area Air Quality Management District rules on which the EPA Industrial Solvent Cleaning CTG was based). The proposed amendments to15A NCAC 02D .0962 are based on understanding that cleaning coating, ink and adhe sive manufacturing equipment is very important since incomplete cleaning of process equipment and tanks can cause cross contamination of manufactured product, negatively impacting product quality and resulting in an off specification product that would need to be disposed of. No change to the rule.
15A NCAC 02Q .0102 Activities Exempted From Permit Requirements Request to amend current definition of graphic arts operations found in 15A NCAC 02Q .0803 to include screen printing and digital imaging operations to qualify them as a graphic arts operation exempt from permit requirements under rule 02Q .0102. Change to 15A NCAC 02Q .0803 definition needs to be considered through separate rulemaking as 02Q .0803 is not part of current proposed rulemaking action.

### I-7

CONCLUSION
Four persons commented for the hearing re cord on the proposed amendments during the comment period.
One commenter expressed support for the proposed amendments to15A NCAC 02D .0962, Industrial Cleaning Solvents, since these amendm ents will allow effective cleaning of process equipment at coatings, ink, and adhesive ma nufacturing operations. These amendments are consistent with the CTG and underlying state rules on which it was based.

The second commenter focused on the Rule 15A NCAC 02D .0961, Offset L ithographic Printing and Letterpress Printing. A few minor text clarifi cations to Paragraphs (f ) and (k) were made. A clarification regarding affected equipment date wa s made to reflect the anticipated effective date of these rule changes. The commenter also proposed a new Subparagraph 15A NCAC 02D .0961(n) to lay out requirements for a facility to make a determinati on that it is not subject to this rule. In order to provide sources maximum flexibili ty to address their site specific configuration and product usage needs, North Carolina air quality rules typically do not impose prescriptive emissions calculation procedures and requirements on sources to determine if they are below applicability thresholds. As a result, the suggest ed language is not included in the final rule. DAQ regional and central office permitting staff, as well as DENR’s free, non-regulatory Environmental Assistance Center staff, can assist affected sour ces with calculating emissions for applicability determinations on a case by case basis.
The third commenter requests that the current definition of graphi c arts operations found in 15A NCAC 02Q.0803 be amended to include both screen printing and digital imaging operations to exempt these operations from permit requirement s under rule 15A NCAC 02Q .0102 as activities already exempted because of category. Because Rule 02Q .0803 is not part of this rulemaking package, the requested amendment of the defin ition cannot be made at this time; however, the definition could be considered for amendm ent through a separate rulemaking action.

The fourth commenter offers no comments at this time.

HEARING OFFICERS’ RECOMMENDATION
The Hearing Officer recommends that the proposed amendments as presented in Chapter II of this hearing report be adopted by the Environmental Management Commission.

- hour Ozone National Ambient Air Quality Standard (NAAQS) Nonattainment Area. USEPA identified the need for adjustment of applicability of the state’s Reasonably Available Control Technology (RACT) rules to meet the requirements of Section 182(b)(2) of the Clean Air Act which requires RACT for all sources addressed by Control Technique Guidelines (CTGs) in nonattainment areas classified moderate and above. The current RACT rules’ applicability is structured such that the RACT requirement for sources in CTG categories applies to major sources with 100 tons of volatile organic compounds or more per year. Amendments to printing related and industrial solvent cleaning RACT rules are in response to industry associations’ requests for language clarifications and flexibilities consistent with the CTGs on which they are based. 15A NCAC 02D .0902 - Applicability, to reflect applicability to all sources in a CTG category in order to meet the Clean Air Act requirement and thus facilitate the redesignation process and include provisions allowing for the shift of requirements to contingency measures upon redesignation of the area consistent with EPA procedures. 15A NCAC 02D .0909 - Compliance Schedules For Sources In Ozone Nonattainment And Maintenance Areas, to update the compliance schedule corresponding to the adjustment in applicability. 15A NCAC 02D .0951 - RACT For Sources of Volatile Organic Compounds, to provide flexibility to comply via the category specific rules in the Section or through approved site specific alternative determinations. 15A NCAC 02D .0961 - Offset Lithographic Printing and Letterpress Printing, in response to industry associations’ comments and requests for language clarification and flexibilities consistent with the CTGs on which it is based including an equivalent rolling, consecutive 12 month applicability threshold consistent with the CTG to provide some relief from a recordkeeping standpoint, clarifying language, and addition of some specificity with respect to recordkeeping. 15A NCAC 18A 02D .0962 - Industrial Cleaning Solvents, in

### 1 Hearing Officer's Suggested Hearing Comments

INTRODUCTION

[Hearing officer]: Good evening ladies and gentlemen. My name is Benne Hutson. I am a member of the North Carolina Environmental Management Commission. My role as hearing officer is to listen to all relevant comment on these proceedings and report them to the full commission. Sitting with me
is Ms. Joelle Burleson. Sh e is with the North Carolina Division of Air Quality, Planning Section.

Some of the staff from the Division of Air Quality are here to assist. Ms. Burleson, please introduce the staff present.

[Ms. Burleson] (Introduces staff)

[Hearing officer]:

This evening we are conducting three public hearings. During Hearing 1, we will take comments concerning amendments to several volatile organic compound (VOC) reasonably available control technology (RACT) rules. During Hearing 2, we will take comment on amendments to two rules that are part of the North Carolina's New Source Review (NSR) permit program. During Hearing 3, we will take comment on an amendment to the Division of Air Quality’s permit exemption rule. Fiscal notes have been written for all of the rule amendments presented in the hearings tonight and were approved and certified by the Office of State Budget and Management. Th ese hearings will be held according to the North Carolina Administrative Procedures Act. The public notice for these hearings has been advertised in the North Carolina Register and five newspapers in the state. Copies of the notice have been sent to those on the official DAQ mailing list. I will enter the public notice, the proposed amendments and the fiscal notes into the hearing record without reading them at this time.

### 2

It would be helpful if any person desiring to comment also submit a written statement for inclusion into the hearing record. Once called to speak, please come to the podium and state your name clearly, identify the rule or rules you are commenting on, and whom you represent.

[Hearing 1 ]:

I will now open the first hearing and take relevant comments on amendments to North Carolina volatile organic compound rules in Section .900 of Chapter 2D.

These proposed amendments respond to Environmental Protection Agency (EPA) comments on
North Carolina’s re -designation demonstration and maintenance plan for the Charlotte-GastoniaRock Hill, NC 8- hour Ozone Nonattainment Area. In their comments on North Carolina’s submittal, EPA identified the need for an adjustment of applicability of the state’s reasonably available control technology (RACT) rules. Section 182(b) (2) of the Clean Air Act (CAA) requires RACT for all sources addressed by Control Technique Guidelines (CTGs) issued by
EPA in areas classified as moderate nonattainment for ozone. North Carolina’s current RACT rule, 15A NCAC 02D .0902, applies only to facilities that have the potential to emit (PTE) greater than or equal to 100 tons of volatile organic compounds (VOC) per year located in the Charlotte-Gastonia-Rock Hill, NC 8-hour Moderate Ozone Nonattainment Area. The proposed amendments bring North Carolina into compliance with federal law by extending this applicability to all VOC sources covered by any CTG in the nonattainment area. The amendments also reduce daily recordkeeping burden for printing operations and exempt cleaning operations of coating, ink, and adhesive manufacturing from VOC content limits in response to
feedback from the industries.

Rule 15A NCAC 02D .0902, Applicability, is proposed for amendment to bring North Carolina into compliance with federal law by extending RACT applicability to all volatile organi c VOC sources located in the nonattainment area and covered by any CTGs. Rule 15A NCAC 02D .0903 Recordkeeping: Reporting: Monitoring, is proposed for amendment to reflect incorporation of the monthly recordkeeping alternative for consistency with the CTG provided in Rule 15A NCAC 02D .0961 in response to indust ry representatives’ comments . Rule 15A NCAC 02D .0909, Compliance Schedules for Sources in Nonattainment Areas, is proposed for

### 3

amendment to clarify compliance schedules for the newly affected facilities. Rule 15A NCAC 02D .0951 RACT for Sources of Volatile Organic Compounds, is proposed for amendment to give affected facilities a choice whether to apply the RACT requirements defined in Section .0900 rules or choose RACT requirements demonstrated to the Director to advance attainment. Rule 15A NCAC 02D .0961, Offset Lithographic Printing and Letterpress Printing, is proposed for amendment to comply with RACT requirements for VOC emissions from heatset inks, fountain solutions, and cleaning materials used in offset lithographic printing operations and for VOC emissions from heatset inks used in letterpress printing operations. Rule 15A NCAC 02D .0962, Industrial Cleaning Solvents, is proposed for amendment to exempt RACT cleaning solvent emission limits applicability for resin, coating, ink, and adhesive mixing, molding, and application equipment cleaning of coating, ink, and adhesive manufacturing. Rule 15A NCAC 02Q .0102 Activities Exempted From Permit Requirements, is proposed for amendment to update a cross reference.

[Hearing 2]:

I will now open the second hearing and take relevant comments on amendments to Rules 15A NCAC 02D .0530, Prevention of Significant Deterioration and 15A NCAC 02D .0531, Sources in Nonattainment Areas, to revise North Carolina’s nitrogen oxides (NO x 

### ) significance level from 140 tons per year to 40 tons per year. Rule 15A NCAC 02D .0530 is also proposed for amendment to update the federal cross-reference in the prevention of significant deterioration rule to reflect the current federal increments for fine particulate matter promulgated on October 20, 2010 in the Federal Register (75 FR 64864).

The EMC amended the prevention of significant deterioration and nonattainment new source review permitting rules in 2010 to establish the significance level for NO x 

### for PM 2.5 

### in North Carolina at 140 tons per year. As part of its rule review of North Carolina’s state implementation plan (SIP), the United States Environmental Protection Agency (USEPA) has determined that,
while the federal rule allows for a demonstration that NO x 

### is not a significant precursor to
formation of PM 2.5 

### , there is not an allowance for states to establish an alternate significance level. As a result, the state significance level must be revised to reflect the federal 40 tons per year significance level.

In 2010, the USEPA added PM 2.5 

### increments under the program. An increment is the maximum allowable increase in ambient pollutant concentration. Federal increments were established for 24-hour and annual averaging periods in Class I, Class II and Class III areas. Adoption of these federal increments is required in order for the USEPA to approve North Carolina’s SIP. The current date of incorporation in the state rule needs to be updated to reflect the current PM 2.5

### 6

The Division of Air Quality identified the need for clarification regarding the interaction of the air toxics rule specific exemptions with the more broadly applicable rule regarding sources that are exempt from the general requirement to obtain a permit. Rule 02Q .0102 specifies which activities are exempt from the requirement to obtain an air quality permit. Rule 02Q .0702 specifies activities which are exempt from the requirement to obtain a permit to emit toxic air pollutants (TAP) and not required to be included in TAP demonstrations. The EMC has previously determined through rulemaking that many of the activities currently exempt from the general requirement to obtain a permit under 02Q .0102(c) should also be exempt from air toxics demonstration and permitting requirements as identified in 02Q .0702(a)(1) through (a)(24). Existing language in 02Q .0102(b)(7) needs to be clarified to reflect this interaction relative to smaller sources such that small sources not be required to be included in an air toxics demonstration or permit retain the exemption from having to obtain an air quality permit.

RE: Volatile Organic Compound Reasonably Available Control Technology (RACT) Rules in 15A NCAC 02D Section .0900 (Specifically .0962 Industrial Cleaning Solvents); ACA Comments

Dear Ms. Burleson:
The American Coatings Association (ACA) 1 

### supports the proposed amendments to15A NCAC 02D .0962 (Industrial Cleaning Solvents), since these amendments will allow effective cleaning of process equipment at coatings, ink, and adhesive manufacturing operations. Further, these amendments are consistent with the EPA Industrial Solvent Cleaning Control Technique Guideline (CTG) (and the Bay Area Air Quality Management District rules on which the EPA Industrial Solvent Cleaning CTG was based on). Cleaning coating, ink and adhesive manufacturing equipment is very important since incomplete cleaning of process equipment and tanks can cause cross contamination of manufactured product and negatively impact product quality and could result in an off specification product that would need to be disposed of.
In advance, thank you for your consideration of our comments. Please do not hesitate to contact me if you have any questions.

Sincerel y,

David Darling, P.E. Senior Director, Environmental Affairs American Coatings Association ** Sent via email **

### February 1, 2013

Ms. Joelle Burleson Division of Air Quality 1641 Mail Service Center Raleigh, North Carolina 27699-1641
Dear Ms. Burleson,
The Specialty Graphic Imaging Association (SGIA), representing the interests of facilities engaged in the use of screen printing and wide format digital imaging and their associated supplier base, submits the following comments to the revisions contained in NAC 02D.0962, Industrial Cleaning Solvents and 15A NCAC 02Q .0102, Activities Exempted from Permit Requirements.
Our comments regarding revisions to the Industrial Cleaning Solvent proposal are minimal. We request that under Section (c) that you also exempt cleaning operations associated with digital printing operations. Appendix C, Summary of NAICS Codes for nonattainment facilities, estimated to meet the applicability criteria recommended in this CTG, specifically lists commercial printing activitie s; the CTG does not identify digital printing, 323115, as meeting the applicability requirements.
When the US EPA CTG for Industrial Cleaning Solvents was first drafted, the Agency did not consider the impact of this document on new and emerging industry sectors. And, when finally released in 2006, the Agency did not address emerging industry sectors. The state rules referenced in the CTG did not include digital technologies, and since 2006, we have seen the inclusion of digital technologies in both solvent cleaning as well as graphic arts air pollution control standards. Specifically, the Bay Area Air Quality Management District in its recently adopted revisions to their graphic arts rule, Regulation 8, Rule 20, exempted digital printing operations and presses from all VOC control requirements, including those associated with cleaning solvents. So that this burgeoning technology is not crippled, SGIA recommends that digital operations be exempted from state’s proposed regulations for cleaning solvent s. The US EPA understood during the development of the final CTG that not all industry sectors were adequately represented during the development of the 1994 document. Further, in the CTG, the US EPA states that “the recommendations contained in this CTG are based on data and information currently available to EPA. These general recommendations may not apply to a particular situation based upon the circumstances of a specific source.” The data and information used by the US EPA was collected in 1994 and only addressed the nine specific industry sectors the proposal lists in Section (b).

### Adoption of this exemption would align North Carolina with other air pollution control districts

that have undertaken adoption of CTG, most notably Illinois and Connecticut.
15A NCAC 02Q .0102, Activities Exempted from Permit Requirements, references Graphic Arts operations as an exempt activity. SGIA respectfully requests that the Department amend its definition of Graphic Arts operations as found in 15 NCAC 02Q.080 to include both screen printing and digital imaging operations as follows:
"Graphic arts operation" means the application of inks to form words, designs, or pictures to a substrate, usually by a series of application rolls each with only partial coverage and usually using letterpress, offset lithography, screen printing, digital imaging technologies, rotogravure, or flexographic process.” (Emphasis added)
By revising this definition, the Department is truly covering all graphic arts operations in the state and offering these facilities the same permitting flexibility enjoyed by other printing processes. Thank you for the opportunity to comment on these important rulemakings. If you have any questions regarding these comments or if you would like to further discuss, please do not hesitate to contact me directly.

Sincerely,

Marcia Y. Kinter Vice President-Government & Business Information Specialty Graphic Imaging Association 703-359-1313 marcik@sgia.org

Impact Summary: State government: No Local government: No Substantial impact: No Federal government: No
Authority: G.S. 143-215.3(a)(1); 143-215.107(a)(5);

Necessity: These amendments are necessary to meet EPA requirements for re -designation of the

Charlotte-Gastonia-Rock Hill Area for attainment of the 1997 8-hour ozone standard and to receive EPA approval for the State Implementation Plan (SIP).



### I. EXECUTIVE SUMMARY
These proposed rule amendments respond to Environmental Protection Agency (EPA) comments on North Carolina’s re -designation demonstration and maintenance plan for the Charlotte-GastoniaRock Hill, NC 8-hour Ozone Nonattainment Area. In their comments on North Carolina’s submittal , EPA identified the need for an adjustment of applicability of the state’s reasonably available control technology (RACT) rules. Section 182(b)(2) of the Clean Air Act (CAA) requires RACT for all sources addressed by Control Technique Guidelines (CTGs) issued by EPA in areas classified as moderate nonattainment for ozone. North Carolina’s current RACT rule, 02D .0902, applies only to facilities that have the potential to emit (PTE) greater than or equal to 100 tons of volatile organic compounds (VOC) per year located in the Charlotte-Gastonia-Rock Hill, NC 8-hour Moderate Ozone Nonattainment Area. The proposed amendments bring North Carolina into compliance with federal law by extending this applicability to all VOC sources covered by any CTG in the nonattainment area.

### OSBM Certified 11- 05 -2012 2

This proposal also amends rule 02D .0909 to clarify compliance schedules for the newly affected facilities, makes conforming changes to 02D .0951, and a corresponding update to related language in 02Q .0102

. Amendments to 02D .0962, which addresses RACT for industrial solvent cleaning, are included, in response to industry comments. These amendments provide compliance alternatives for coatings, inks, adhesives, and resins manufacturers that are consistent with the underlying solvent cleaning CTG recommendations. Amendments to 02D .0961, and corresponding update to Rule .0903, that address RACT for lithographic and letterpress printing are included to clarify existing language and add an equivalent alternative applicability threshold consistent with the CTG.

The Division of Air Quality anticipates EPA will approve the re -designation request and maintenance plan once the proposed applicability change has been made. Upon approval of the maintenance plan and re -designation request, EPA will publish a notice in the Federal Register designating the area as having achieved attainment with the 1997 ozone standard. In extreme circumstances, failure to adopt these rules could lead to more federal regulation and, eventually, potential sanctions on highway transportation funding.

The Clean Air Act requires facilities that are already in compliance with RACT shall continue to comply with the RACT requirements even after the area becomes attainment. For the most likely scenario, the division estimates that this rule change will have no direct impacts on affected parties

. If , as expected, re -designation occurs prior to the compliance date of the amendments, then t he proposed rule changes will apply only under the contingency plan and would become applicable only if: (1) the area later fails to meet the 1997 standard and (2) implementation of the proposed amendments would assist in bringing the area back into attainment as part of the contingency plan. This important administrative correction fixes the SIP inadequacy and would generate no direct costs and some indirect benefits

. Based on current knowledge of the federal approval procedures, this is the most probable outcome

.

T he impacts estimated in this analysis were developed for a worst-case scenario that is detailed in the risk analysis section. Although such impacts could be substantial, they are highly unlikely and not expected to occur

. Under the worst-case scenario, DAQ estima te s private industry would incur annual costs of up to $9. 7 million, and cost-savings of $18.4 million. Combined annual impacts amount to net cost-savings of up to $8.8 million (with potential costs and benefits attributed to different entities)

. There are no impacts on the expenditure of state funds. The North Carolina Division of Air Quality would not experience new costs associated with these proposed rule changes. Local governments operate three coating and adhesive facilities and these may incur costs up to $39,000 annually. The federal government operates one coating and adhesive facility that may incur costs up to $3,600 annually to comply with the new regulations. The general public may benefit from cleaner air, and workers in facilities that use VOC materials may be exposed to fewer toxics if solvent switching is the compliance mechanism of choice. These benefits are not quantified because they are not expected to occur under the most likely scenario

. All of the estimates in the risk analysis were made using worst-case scenario assumptions that: (1) all VOC emissions from affected facilities are coming only from sources of VOC emissions covered by control techniques guidelines (CTG), (2) all affected facilities are currently not meeting RACT

### OSBM Certified 11- 05 -2012 3

requirements, (3) EPA does not re-designate the area to attainment status prior to the compliancedate, and (4) there is a violation of the 1997 ozone standard. In reality, even if EPA does not redesignate the area or if there is a future violation of the 1997 ozone standard, DAQ expects compliance costs to be much lower because many facilities may already be meeting RACT requirements or not have emissions covered by CTG. In addition, the current section .0900 provides a couple of simple, low-cost options for facilities that would need to achieve compliance with these new RACT requirements.
The anticipated effective date of these amendments is May 1, 2013.



### II. BACKGROUND AND PURPOSE
These amendments would revise the applicability of the volatile organic compound (VOC) reasonably available control technology (RACT) rules to meet all Clean Air Act and EPA requirements for re -designation of the Charlotte-Gastonia-Rock Hill Area for attainment of the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) to finalize NC SIP (State Implementation Plan) approval by EPA.

On November 15, 2011, EPA determined that the Charlotte-Gastonia-Rock Hill, NC, 8-hour Moderate Ozone Nonattainment Area had attained the 1997 8-hour ozone standard. This determination(known as a Clean Data Determination) was based upon complete, quality-assured, qualitycontrolled, and certified ambient air monitoring data from 2008

– 2010. This determination means the division could request that EPA change its designation from nonattainment to attainment, making the area a maintenance area. The state must amend the current rules to extend applicability of the RACT rules to facilities in Control Technique Guideline (CTG) categories with less than 100 tons per year of VOC emissions in order to receive EPA approval of the re -designation

. A “nonattainment” classification means that air quality in a particular region does not meet (or “attain”) a federal air quality standard. Under the Clean Air Act, the EPA sets limits on how much pollution can be in the air. These pollution limits are called National Ambient Air Quality Standards (NAAQS). There are NAAQS for six common air pollutants including ground-level ozone (O 3 

### ).

Ground level ozone, which we breathe, can harm our health. Even relatively low levels of ozone can cause health effects. People with lung disease, children, older adults, and people who are active outdoors may be particularly sensitive to ozone.

The Clean Air Act requires EPA to review its standards based on scientific evidence every five years to ensure they still effectively protect human health and the environment. When an area’s monitored air pollution exceeds the NAAQS , EPA designates it as a nonattainment area. This designation is determined by a formula that uses the number of times the standard is exceeded each year. The formula includes three years of data to ensu re that an area isn’t designated as nonattainment because of one unusual year.

When an area is designated as a nonattainment area for ground-level ozone, the state is required to develop a SIP and submit it to EPA. A SIP is a plan for restoring air quality and bringing the area back into attainment status as quickly as possible. The SIP must define what actions will be taken to control air pollution, how these actions will lead to attainment, and project when air quality will meet the relevant standards. EPA then evaluates the SIP for approval.

### OSBM Certified 11- 05 -2012 4

If a state doesn't complete a SIP to improve air quality, the EPA may impose a federal plan (Federal Implementation Plan, or FIP). A federal plan may require solutions that are not the best to fit a particular area.
Nonattainment areas that don't clean up their air pollution could receive cuts in federal transportation funding if new highway projects could add to the air pollution problem. EPA could also withhold all or part of the grant funds it provides to the state to support air quality monitoring, planning, and control programs. The Division cannot estimate the probability that EPA would impose such sanctions, but the Division recognizes that such a situation could have significant financial consequences for the state if it were to occur.

Once monitoring data show air quality has improved, the state can request that EPA re -designate an area from nonattainment to attainment, making it a maintenance area

. A maintenance area is an area that has been re -designated to attainment for a NAAQS. EPA can only approve this request if the following conditions are met: (1) air quality monitoring data shows the area meets the standard; (2) reductions in the area’s emissions are permanent and enforceable; (3) the SIP developed for the area meets the requirements of the federal Clean Air Act and is fully approved by EPA; (4) EPA fully approves a 10-year maintenance plan for the area; and (5) the area meets requirements of the Clean Air Act for infrastructure SIPs and nonattainment areas.

North Carolina has already met most of the requirements for EPA approval. Nevertheless, the EPA noted that in order to receive SIP approval DAQ must amend the RACT rule applicability requirements to cover facilities that have PTE VOC emissions of less than 100 tons per year. This rulemaking is being undertaken to meet the CAA requirement and ensure approval of the st ate’s SIP.
The following section outlines the proposed changes to the existing RACT rules that are necessary to receive SIP approval from the EPA. Unless otherwise noted, none of the proposed rule changes would apply under the scenario that DAQ believes is the most likely (i.e. EPA re-designates the Charlotte-Gastonia nonattainment area to a maintenance area). The impacts associated with these proposed rule changes would only occur under either of the following highly unlikely scenarios: 1) the EPA does not re-designate the area as a maintenance area or 2) the maintenance area fails at some future date and the DAQ director chooses to implement the proposed changes as part of a contingency plan to re-attain maintenance-area status. The impacts under these unlikely scenarios are outlined in detail in the risk analysis section of this fiscal note (Section VI).

There are five proposed changes to Rule 15A NCAC 02D.0902 Applicability for Sources in Nonattainment Areas:

1. The first set of changes in Paragraph (f ) will extend RACT to apply to all sources addressed by CTGs in the Charlotte-Gastonia nonattainment area and clarify the provision that certain rules continue to apply statewide. A statement added to the end of Paragraph (f) clarifies the applicable RACT requirements and referenc es the rules for achieving compliance.
In Paragraph (g) “subject to this Section before the re -designation to attainment” is replaced with “subject to Paragraph ( f) of this Rule that achieved compliance in accordance with Rule .0909 of this Section” and “Facilities with the potential to emit less than 100 tons

### OSBM Certified 11- 05 -2012 5 of volatile organic compounds per year for which the compliance date in Rule .0909 of this Section has not passed before re -designation of the area to attainment for the 1997 o zo ne standard shall comply in accordance with Paragraph (h) of the Rule” in Paragraph (g) is added to define the range of applicable facilities in accordance with Section 182(b)(2) of the Clean Air Act and allow for transition of the requirements to contingency measures upon re -designation of the area consistent with EPA procedures.

2. This proposal would remove outdated language in Paragraph (h) to address a past potential scenario under which the area might have been bumped to a higher classification with a lower applicability threshold. Replacement language will address the contingency plan in the event that a violation of the 1997 ozone standard occurs. The phrase “If EPA reclassifies the nonattainment area as serious for ozone under Section 182 of the federal Clean Air Act, the rules in this Section shall apply to facilities in Cabarrus, Gaston, Lincoln, Mecklenburg, Rowan, and Union Counties and Davidson and Coddle Creek townships in Iredell County with the potential to emit at least 50 tons of volatile organic compounds per year. Within 60 days of the reclassification...” and the phrase “shall notice the applicability of these Rules to these facilities in the North Carolina Register and... ” are replaced with “ If a violation of the 1997 ambient air quality standard for ozone occurs in the maintenance area, the Director shall initiate technical analysis to determine the control measures needed to attain and maintain the 1997 8-hour ambient air quality standard for ozone. By the following May 1, the Director shall implement the specific stationary source control measures contained in this Section that are required as part of the control strategy necessary to bring the area into compliance and to maintain compliance with the 1997 8- hour ambient air quality standard for ozone. The Director shall implement the rules in this Section identified as being necessary by the analysis by notice in the North Carolina Register. The notice shall identify the rules that are to be implemented and shall identify whether the rules implemented are to apply in the areas listed in Paragraph (f) of this Rule. At least one week before the scheduled publication date of the North Carolina Register containing the Director 's notice implementing rules in this Section,” in Paragraph (h) to specify measures required by the CAA in case a violation of the 1997 ambient air quality standard for ozone would occur.

3. The third group of the proposed changes makes several minor clarifications by adding the phrase “to facilities located” in Paragraph (e) and the word “located” in Paragraph (f).

4. The p hrase “day unless specified otherwise in this Section” was added to Paragraph (b). This update was requested by Printing Industries of America. This amendment provides some flexibility for alternative compliance options that is specified by the amendment to the rule .0961.

5. Finally, adding the phrase “ unless provisions specified in Paragraph (d)(1) of this Rule are applied” in Paragra ph (c) clarifies interaction of Paragraphs (c) and the exceptions in Paragraph (d) that exempt laboratories that emit less than 800 pounds of VOC per month from provisions of the Section.
The Rule 15A NCAC 02D .0903(a)(2), was updated by adding the phra se “unless otherwise specified in the Section” t o reflect incorporation of the monthly recordkeeping alternative provided in 02D .0961 in response to industry representatives ’ comments and for consistency with the CTG.

### OSBM Certified 11- 05 -2012 6

There are also five changes to Rule 15A NCAC 02D .0909, Compliance Schedules for Sources in Nonattainment Areas:

1. First, a change would add the word “Moderate” in Paragraph (d), (f) and (g) and delet e the phrase “and Charlotte ozone nonattainment area” in Paragraphs (f) and (g) to define th e status of the nonattainment area in accordance with the current 8-Hour Ozone Classifications for the 1997 standard.

2. Subparagraphs (i) and (ii) in Paragraphs (c)(2)(B) and (d)(2)(B) are deleted as unnecessary because rules in Section .0900 that were amended in 2010 have already incorporated EPA CTG recommendations on VOC content limits.

3. Paragraph (c)(2)(C) is amended to allow two years for achieving compliance if low solvent coating technology is to be used.

4. Paragraph (d)(1)(C) and (D) are modified to reflect the compliance schedule for the newly affected facilities establishing a compliance date of May 1, 2015 for compliance via use of solvent coating technology and May 1, 2016 for compliance via control devices

. (These dates are expected to provide EPA sufficient amount of time to approve the redesignation and avoid subjecting these facilities to RACT prior to these occurring.)

5. Finally, these proposed rule changes also make several minor clarifications to avoid ambiguity and confusion.
In addition, the amendment to Paragraph 2D .0902(h) clarifies that compliance with necessary contingency requirements will be initiated only after a violation of the 1997 ambient air quality standard for ozone occurs and the measures are determined to be necessary as part of the control strategy to bring the area into compliance and maintain compliance with the 1997 ozone standard.

Amendments to Rule 15A NCAC 02D .0951, RACT for Sources of Volatile Organic Compounds, give affected facilities covered by CTG recommended RACT rules of the Section .0900 a choice whether to apply the RACT requirements defined in .0900 Section rules or choose RACT requirements demonstrated to the Director to advance attainment.
The current Rule 15A NCAC 02D .0961, Offset Lithographic Printing and Letterpress Printing, offers control options to comply with RACT requirements for VOC emissions from heatset inks, fountain solutions, and cleaning materials used in offset lithographic printing operations and for VOC emissions from heatset inks used in letterpress printing operations. The division is proposing changes to reduce daily recordkeeping burden based on feedback from the industry

. Following the original adoption of the rule in 2010, the Printing Industry of America, a trade group, commented and requested several clarifications of the rule language. The proposed amendments are made in response to these comments and include clarification of definitions of “offset lithography”, “sheet

- fed printing” and “web printing”. The phrase, “listed in rules .0101, .0902 of this Section and in Paragraph (a)(1) through (10) of this rule shall apply” is added to Paragraph (a) to indicate that some definitions that apply to this rule can be found in rules .0101 and .0901. Wording in Paragraphs (b), (c), (d), (e), (f), (g), (h), (i), and (l) were updated. There are no impacts from these

### OSBM Certified 11- 05 -2012 7

changes to the affected parties other than to eliminate confusion, misunderstanding, and typographical errors.
In addition to the language update in Paragraph (b), the new Subparagraph (b)(2) was added to address the Printing Industries of America ’s concerns regarding economic and technical feasibility of compliance period frequency established on a daily basis. The association noted in its comments that the cost of developing a daily recordkeeping system to meet the requirements of the current rule is financially impracticable for printing operations. Monthly recordkeeping requirements decreases cost to the printing facility by ten-fold when compared to monthly recordkeeping.

The contention of the printing association regarding higher recordkeeping costs is supported by the following facts:
(1) An accurate determination of process emissions on daily basis requires development and maintenance of extremely detailed daily records. The variety, combinations and consumption rate of inks alone would make this a costly and burdensome task. A typical facility can easily use 20 different inks during a day. However, a particular container of ink opened may take several days, weeks, or months to be completely consumed. (2) Separate records for material consumption will have to be developed for each material used on each press. In the situations where a production run may involve more than one day, the press would have to be stopped at the end of each day and all of the input materials such as the ink, fountain solution, cleaning solution, coating, and other miscellaneous chemicals that were consumed would have to be measured in some fashion. (3) The ink consumption rates are better gauged over a longer averaging period because consumption based on purchasing can be correlated with measured values.
Paragraph (f) was updated to clarify a threshold for emission limitations of a single web offset lithographic printing press dryer or letterpress printing heatset press. The provisions of the old Paragraph (h) were moved to the Paragraph (f) to locate in one paragraph for clarity the threshold for add-on control and add-on control provisions. Wording in Paragraph (f) was revised to eliminate confusion and the provisions of Paragraph (i) in the current version were moved to new Subparagraph (f)(2)(C), in response to industry ’s comments, to reflect specific VOC outlet concentrations consistent with EPA ’s CTG recommendations.
Paragraphs (g) and (i) in the current version were deleted and all testing requirements were moved to the new Paragraphs (h ) and (i) to locate all testing requirements in one place. The new Paragra ph s (h) and (i) define the usage of approved test methods in accordance with CTG recommendations. The cost of testing is the same for all test methods; consequently, th is change wouldn’t impose new costs

. Paragraph (j) was updated to clarify compliance demonstration with RACT applicability. The rest of Paragraph (j) was changed to provide the appropriate emission/retention factors and capture efficiencies. Since the applicability threshold is being lowered, the appropriate emission/retention factors and capture efficiencies will give many small er printers an easy way to determine applicability. Per industry comments some small printers do not know how to calculate VOC emissions, but they do know how much material they purchase and use

. The paragraph gives these sources the ability to calculate their emissions more readily. The material-use factors have been approved by EPA and are consistent with the 1998 Potential to Emit (PTE) Guidance for

### OSBM Certified 11- 05 -2012 8

Specific Source Categories and its accompanying technical support document.
The language in Paragraph (k) was updated in response to industry ’s request to clarify conditions when VOC content or vapor pressure limits apply to cleaning materials used for cleaning a press, press parts, or to remove dried ink from areas around the press.
Finally, the new Paragraph (l) was updated to address the industry recommendation of providing some specificity regarding recordkeeping and monitoring requirements while retaining facility flexibility to address site-specific considerations through the permitting process.

Proposed amendments to Rule 15A NCAC 02D .0962, Industrial Cleaning Solvents, exempt cleaning solvent emissions from RACT applicability by changing 0.42 pounds per gallon of VOC content in cleaning material, as recommended for RACT applicability, to 1.67 pounds of VOC per gallon per EPA recommendations. These provisions apply only to resin, coating, ink, and adhesive mixing, molding, and application equipment cleaning of coating, ink, and adhesive manufacturing as a category with specific exemptions under Bay Area Rules 8-4 116 and 8-4-117 on which the CTG was based.

The Rule 15A NCAC 02D .0962 defines measures for controlling emissions of VOC from the use, storage, and disposal of industrial cleaning solvents. These measures include work practice standards, limitations on VOC content of the cleaning materials, and an optional alternative limit on composite vapor pressure of the cleaning materials. They also allow facilities to include the use of add- on controls with an overall emission reduction of at least 85 percent by mass.

In comments on the existing rule, industry representatives recommended exempting coating, ink, and adhesive manufacturing from VOC content limits established in .0962 since 0.42 pounds per gallon of VOC content is not feasible for industrial solvent used for cleaning coatings, ink, adhesive and resin manufacturing equipment.

Coatings- and ink-manufacturing facilities have instituted pollution-prevention programs where they clean and rinse process equipment with recycled/reclaimed solvents. They use the solvent until it is dirty and either reclaim the solvent onsite or send it offsite for reclamation. The reclaim ed solvent is then used again for cleaning and rinsing process equipment. Reusing solvents is cost effective and minimizes the generation and disposal of hazardous wastes. The 50 g/l (same as the 0.42 lb/gal) limit would force manufacturers to dispose of all existing solvents and purchase compliant solvent at considerable cost. These costs impacts are considered especially problematic by the industry representatives given the recent economic downturn.

Cleaning manufacturing equipment is very important since incomplete cleaning of process equipment and tanks can cause cross-contamination of manufactured products, negatively impact product quality, and could result in an off-specification product. Chemistries also vary considerably from batch to batch of product and are very difficult to clean unless effective cleaning solvents are used. The 50 g/l cleaning solvent limit essentially only leaves two compliance options: exempt solvents or force the use of caustic cleaning systems.

While low-VOC solvents are not effective for cleaning equipment used to manufacture current coating formulations, these solvents are even less effective at cleaning newer low-VOC products now coming into the market. This is especially true for industrial-maintenance coatings that are high in solids, involve two components and/or have exotic chemistries.

### OSBM Certified 11- 05 -2012 9

The proposed amendments exclude solvent cleaning operations of specific equipment in the inks, coatings, and resins manufacturing sector from the 0.42 pounds per gallon of VOC limit, as long as cleaning is conducted using one or more compliance options, including an alternative solvent content limit of 1.67 pounds of VOC per gallon, use of a control device, use of solvents with content greater than 1.67 pounds/gallon limited to 60 gallons per month, and work practices for solvent cleaning in this sector. These options are consistent with those associated with the Bay Area rules on which the CTG recommendations are based.
Finally, Rule 15A NCAC 02Q .0102, Activities Exempted from Permit Requirements. Paragraph (b)(5) of the Rule 02Q .0102 is revised to update a cross reference.

III. COSTS IMPACTS BY AFFECTED PARTIES For the most likely scenario, the division estimates that these amendments will have no direct impacts on affected parties. If, as expected, re-designation occurs prior to the compliance date of the amendments, then the proposed rule changes will apply only under the contingency plan and would become applicable only if: (1) the area later fails to meet the 1997 standard and (2) implementation of the proposed amendments would assist in bringing the area back into attainment as part of the contingency plan. This important administrative correction fixes the SIP inadequacy and would generate no direct costs; the only impacts under the most likely scenario would be the impacts associated with the EPA’s re -designation. Based on current knowledge of the federal approval procedures EPA re-designation is the most probable outcome

.

IV. BENEFITS.
The primary benefit of this set of amendments is to meet the Clean Air Act requirements and to obtain approval of the VOC RACT state implementation plan by EPA. Without the applicability amendments, EPA would not be able to approve the re -designation and maintenance plan for the Charlotte-Gastonia-Rock Hill 1997 ozone nonattainment area and requirements for moderate nonattainment areas such as nonattainment new source review would continue to apply even though monitoring data show compliance with the 1997 8-hour ozone standard. The EPA approval can mitigate the consequences of a SIP deficiency including possible disapproval and, lacking correction within required timeframes, implementation of a federal program. If not eventually corrected, potential sanctions on highway transportation funding could be imposed by EPA.

In the unlikely event that the area is not re -designated or the requirements are determined to be necessary in response to a future violation as a contingency measure, the proposed rule changes may potentially decrease VOC emissions from printing, solvent coating, and cleaning operations, and because many VOCs also are air toxics, the proposed amendments may decrease the emissions of air toxics. An added potential co-benefit of lower VOC emissions from the implementation of the CTGs and work practice standards includes less exposure to hazardous air pollutants to those working at such facilities.

V. CONSIDERATION OF ALTERNATIVES
Several alternative approaches to address the applicability issue were explored and considered in development of the proposed rule changes.

### OSBM Certified 11- 05 -2012 10

Alternative 1

–

Retain the Status Quo Retaining the current rule as is would result in EPA not being able to approve the RACT state implementation plan and a disapproval of that portion of the SIP. The state would have 18 months to address the SIP deficiency and EPA would have to approve the correction within 24 months from the disapproval. At 24 months EPA would be required to implement a federal program. If a deficiency occurred and was not corrected and approved within the timeframes, the federal government could impose sanctions on highway transportation funding until the state corrects the SIP deficiency

. As a result EPA would not be able to approve the re -designation request and maintenance plan for the North Carolina area of the Charlotte-Gastonia-Rock Hill nonattainment area despite the fact that monitoring results show compliance with the 1997 8-hour ozone standard. The area would continue to be considered moderate nonattainment for the 1997 8-hour ozone standard and associated requirements, such as nonattainment new source review, would continue to apply until such time as the requirements could be met.
Alternative 2- Include applicability to less than 100 tpy VOC facilities only in contingency measures Given that the area already has a Clean Data Determination relative to the 1997 8-hour ozone standard and the fact that North Carolina, like other states in the southeastern United States, has an abundance of biogenic VOC emissions and is in a nitrogen oxides (NOx)-limited environment with respect to ozone formation, staff explored the possibility of including applicability of the RACT requirements for less than 100 tpy sources only in the contingency measures provisions. Based on further review of the CAA, EPA re -designation procedures, and discussions with EPA staff, this approach would not be consistent with the requirements of the Clean Air Act. As a result EPA would not be able to approve the RACT SIP and the re -designation request. Therefore this approach was ruled out since it would not successfully address the applicability issue identified by EPA.

VI . RISK ANALYSIS This analysis concludes that there are no direct costs and likely indirect benefits due to the proposed amendments under the most likely circumstances. In an effort to identify all possible outcomes, worst-case scenario cost estimates were also developed for this analysis

. Even though the possibility of such outcome is unlikely, these impacts are discussed below in this section. The Division of Air Quality does not anticipate any costs or cost-savings to occur as a result of this rulemaking

.
Under the wor st -case scenario, DAQ estimates private industry would incur annual costs of up to $9. 7 million, and cost-savings of $18.4 million. Combined annual impacts amount to net cost-savings of up to $8.8 million (with potential costs and benefits attributed to different entities)

. There are no impacts on the expenditure of state funds. The North Carolina Division of Air Quality would not experience new costs associated with these proposed rule changes. Local governments operate three coating and adhesive facilities and these may incur costs up to $39,000 annually. The federal government operates one coating and adhesive facility that may incur costs up to $3,600 annually to comply with the new regulations.
These cost estimations were made for the worst-case scenario assuming that: (1) all VOC emissions from affected facilities are coming only from sources of VOC emissions covered by control techniques guidelines (CTG); and (2) all affected facilities are currently not meeting RACT requirements. The federal, state, and local costs are part of the aggregated impact. The North Carolina Division of Air Quality would not experience new costs or benefits associated with these proposed rule changes under the worst-case scenario

.

### OSBM Certified 11- 05 -2012 11

If (1) the maintenance area later fails to meet the 1997 standard and (2) the Division of Air Quality Director implements the proposed amendments as part of the contingency plan to bring the area back into attainment, there would be potential impacts. This scenario is highly unlikely because the air monitoring data collected during the last three years has consistently shown compliance with the 1997 air quality standard for ozone. The Division doesn’t expect any changes in ozone formation related to the changes in volatile organic compounds emissions that would affect attainment status.

In addition North Carolina, like most areas in the southeastern United States, is in what is known as a “NO x 

### (nitrogen oxides)- limited” environment with respect to the formation of ground -level ozone. Oz one is formed through the photochemical reaction of VOCs, NO x 

### and sunlight in the atmosphere. North Carolina has a large amount of biogenic VOCs emitted from trees and other living sources. Industrial and government facilities are smaller sources of VOC emissions compared to biogenic sources. The amount of NO x 

### available in the atmosphere is far less than needed to react with the abundance of VOC in the atmosphere and, as a result, is the limiting factor in how much ozone forms. As such, the director would be unlikely to invoke the proposed amendments as part of the contingency plan because they would have little impact on ozone reduction

. These estimates were developed to demonstrate a worst-case scenario. In reality, the expected cost to regulated entities is zero.
The proposed amendments to Rules 15A NCAC 02D .0902, Applicability, 15A NCAC 02D .0909, Compliance Schedules for Sources in Nonattainment Areas, Rule 15A NCAC 02D .0951, RACT for Sources of Volatile Organic Compounds and Rule 15A NCAC 02Q .0102, Activities Exempted from Permit Requirements, have the potential to affect five entities: regulated private facilities, facilities operated by local governments, a federal facility, the regulatory programs that oversee this area and the general public. Th e worst-case scenario costs and benefits are presented below, organized by entity.
We adjusted EPA values from 2005 to current dollars by using the producer price index for inflating values since these chemicals are inputs to industrial processes.

The current versions of the rules 02D .0902, .0903, .0909, .0951, .0961, .0962, and 02Q .0102 serve as the baseline for these proposed amendments. Under this version all facilities with potential to emit less than 100 tpy of VOC emissions located in the Charlotte-Gastonia-Rock Hill 1997 8-hour ozone area are not subject to RACT requirements and are subject to work practice requirements under Rule 02D .0958 rule. The current versions of the rules 02D .0902, .0909, .0951, and 02Q .0102 also include some obsolete language relative to 1-hour ozone NAAQS requirements that has become outdated due to revocation of that standard and is no longer enforceable.

Private Industry The newly regulated community under the proposed rules includes the owners or operators of approximately 150 facilities with potential to emit 100 tpy or less of VOC emissions located in the Charlotte-Gastonia- Rock Hill ozone area and covered by CTG documents. However, this list doesn’t include the cleaning solvent emissions from cleaning of resin, coating, ink, and adhesive mixing, molding, and application equipment of coating, ink, and adhesive manufacturing. Exempting cleaning solvent emissions is consistent with EPA recommendations to exclude facilities with cleaning operations that are subject to specific rules and exemptions under Bay Area Rule 8-4-117

### OSBM Certified 11- 05 -2012 12

from RACT applicability. 1 

### The cost savings associated with excluding these facilities is estimated separately. The Division of Air Quality estimates that more than 95 percent of the affected businesses are small businesses, or facilities with 500 or fewer employees. This estimation was made using the database presented at www.referenceusagov.com

. The proposed changes to the Rule .0902 will make facilities with the potential to emit VOC emissions less than 100 tpy located in the 8-hour Charlotte-Gastonia-Rock Hill ozone area subject to the RACT requirements for sources in categories covered by CTGs. These requirements are established in rules .0909, .0918, .0919, .0922, .0923-.0924, .0930, .0931, .0935, .0937, .0943, .0944, .0947-.0949, .0951, .0952, .0959, .0961-.0968.
These rules have established requirements for achieving RACT by offering two alternatives: either by using materials with VOC content that is low enough to achieve the limits during application, or by reducing the amount of VOC emitted through the use of add- on controls. EPA noted in the CTGs’ recommendations that pollution prevention, including product substitution/reformulation, is the most prevalent control technique being used by facilities subject to RACT requirements. Add-on control systems are available to these facilities, but EPA estimated during the development of the 2002 National Emission Standards for Hazardous Air Pollutants (NESHAP), that only a few facilities would install add-on control devices as a result of the standard. The capital cost and annual operation cost of add-on control devices usually make them less desirable than other compliance options for reducing VOC emissions from spray-coating operations. 2



### Rule 02D .0902 also includes provisions that allow the requirements to be shifted to contingency measures upon re -designation of the area to attainment status.
The proposed changes to the Rule 02D .0909 will update language to better reflect the 1997 nonattainment area consistent with updates to the applicability rule and establish a compliance schedule for the newly affected sources.
The amendments to Rule 15A NCAC 02D .0951, RACT for Sources of Volatile Organic Compounds give affected facilities covered by CTG recommended RACT rules of Section .0900 a choice whether to apply the RACT requirements defined in .0900 Section rules or choose RACT requirements demonstrated to the Director to advance attainment.

Th e proposed change to the Rule 02Q .0102 corrects a cross-reference and has no effect on cost estimation.
This cost analysis is based on EPA’s control techniques guidelines (CTGs) published between 2006 and 2008. EPA noted that to develop these recommendations, it conducted a model plant analysis, in which it evaluated hazardous air pollutant (HAP) emissions associated with different kinds of coating processes, the emission reduction capabilities of various control options, and the costs of such controls. The model plants were developed to represent a range of sizes and emissions. EPA figures were reported using 2005 dollars. In this analysis, all EPA figures have been inflated into 2012 dollars using the Producer Price Index produced by the Bureau of Labor Statistics for total manufacturing industries. This index inflated original 2005 figures by 38.3 percent.

1 Control Techniques Guidelines for Industrial Cleaning Solvents , EPA-453/R- 06 -001, 2006/09 2 ( Control Techniques Guidelines for Large Appliance Coatings ). EPA 453/R- 07 -004, 2007/09

### OSBM Certified 11- 05 -2012 13

The following assumptions were used to develop an algorithm of cost estimation for the facilities that could be affected by these changes in the event that the area is not re -designated prior to the proposed compliance date:

1. All VOC emissions of affected facilities are only from sources covered by control techniques guidelines (CTG).

2. DAQ assumes that the overwhelming majority of the affected facilities are most likely to choose the low-VOC materials alternative to implement the levels of control required by these rule changes. This assumption was made for two reasons. First, EPA’s final rule “Approval and Promulgation of Implementation Plans and Designations of Areas for Air Quality Planning Purposes; Charlotte- Gastonia-Rock Hill, NC and SC; Determination of Attainment of the 1997 8- Hour Ozone Standard” published in 40 CFR Part 52 on November 15, 2011, 3 

### indicates that the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) has been achieved without add-on control installation. Secondly, according to EPA calculations, the cost of low-VOC content material is not significantly greater than the cost of materials with higher-VOC contents. Thirdly, the use of add-on controls to reduce emissions from typical application processes is a more costly alternative.

3. Due to the fact that the current rules do not require any VOC reductions from the newly affected facilities, DAQ makes an assumption, consistent with EPA assumptions regarding VOC emissions reductions, that the facilities have to reduce VOC emissions by 81 percent to comply with the RACT requirements. 4



### 4. DAQ made a logical assumption that the facilities located in Mecklenburg County, for which DAQ was unable to obtain relevant data, use the same VOC content material for similar production units as the facilities located in Mooresville Region (from which DAQ was able to obtain relevant data)

. Emission reductions are calculated separately for each type of operations: (1) industrial cleaning solvents; (2) coating and adhesive units; (3) lithographic printing and letterpress printing units; and (4) flexible printing units in accordance with EPA recommendations. All costs are calculated as the difference between cost of compliance with current rule requirements and a projected cost of compliance with the RACT requirements. Current rules require these facilities to maintain certain working standards to minimize VOC emissions. However, there are no limits required to maintain certain VOC content in material or VOC emissions for the newly affected facilities.


### Cost estimation for the facilities with the Industrial Cleaning Solvents. The number of facilities with industrial cleaning solvents affected by these amendments is calculated below by using EPA data published in Control Techniques Guidelines for Industrial Cleaning Solvents, Appendix D. 5

3 Approval and Promulgation of Implementation Plans and Designations of Areas for Air Quality Planning Purposes; Charlotte- Gastonia-Rock Hill, NC and SC; Determination of Attainment of the 1997 8-Hour Ozone Standard 4 Memo from William T.

### OSBM Certified 11- 05 -2012 14

According to this data, there are 154 facilities located in the 8-hour Charlotte-Gastonia-Rock Hill ozone area having a total 13,242 ton/yr baseline level of VOC emissions from solvent utilization during cleaning operations. This number includes 15 facilities that have potential to emit 100 tons or more VOC emissions per year (total actual 2010 emissions of 1,148 ton/yr), which already have been in compliance with the RACT requirements since 2010 when the compliance with these requirements became effective for such facilities. Thus, only 139 facilities with a total of 12,094 tons/yr of VOC emissions from solvent utilization during cleaning operations would need to comply with RACT requirements under the proposed rules. These facilities are the subject of these cost estimations.
In accordance with EPA methodology, DAQ did not include in this analysis cleaning solvent emissions from CAA Section 183(e) sources; cleaning solvent emissions from research and development facilities; emissions from manufacturing and assembly of electrical and electronic components; and emissions from activities that are covered by provisions of other rules. EPA also excluded sources that were exempted under the Bay Area rules in its CTG calculations. Thus, the cost savings associated with proposed amendments regarding industrial solvent cleaning of adhesive mixing, molding, and application equipment for coating, ink, and adhesive manufacturing are estimated separately in this assessment.

To estimate the cost of compliance for the facilities with the industrial cleaning solvents, DAQ used EPA’s assumption that eight p ercent of all industrial cleaning VOC emissions come from a “degreasing” or cold solvent cleaning/stripping classification and the remaining 92 percent comes from other solvent cleaning operations.
Industry association representatives estimated that facilities currently use solvents with an average VOC concentration of 500 grams/liter (4 .2 lb s/gal) for industrial cleaning operations. The RACT requirements limit VOC concentration to 50 grams of VOC per liter (0.42 lbs/gal) of cleaning material. However, based on comments from industry representatives, the 50 g/l limit is not feasible for industrial solvent used for cleaning coatings, ink, adhesive and resin manufacturing equipment. The proposed amendments exclude these operations from the 0.42 lb/gal limit in Rule .0962 for consistency with EPA recommendations in the C ontrol Techniques Guidelines for industrial cleaning solvents (page 9). 6 

### The associated cost savings is calculated separately (below) in this assessment.

For other sources DAQ estimated baseline emissions and emission reductions from parts cleaners and other solvent cleaning operations by using EPA ’s figures presented in the Control Techniques Guidelines for Industrial Cleaning Solvents

. 7



### Parts Cleaners The total VOC Emissions from Parts Cleaners used by the facilities with less than 100 tpy potential VOC emissions located in the 8-hour Charlotte-Gastonia-Rock Hill ozone area are equal to eight percent 8 

### of all VOC emissions from cleaning operations of all solvent cleaning facilities located in the 8-hour Charlotte-Gastonia-Rock Hill ozone area:
12,094 tons/yr x 8% =968 tons/yr

8 , 9 Control Techniques Guidelines for Industrial Cleaning Solvents ,

### OSBM Certified 11- 05 -2012 15

VOC emissions from 139 (facilities) x 8% = 11 (part cleaning facilities)
In accordance with data provided by the American Coating Association (ACA,) the average VOC concentration (density) of the solvents used by these facilities is 500 g/liter. After the replacement of the organic solvent that these facilities are currently using with a cleaning solution that has 50 g/liter VOC content (concentration) the VOC emissions would be as follows:
968 tons/yr * (50 g/liter/500 g/liter) = 96.8 tons/yr

The actual emission reduction from switching to low-content VOC material is:
968 tons/yr

–

96.8 tons/yr = 871.2 tons/yr

Using the EPA assumption 9 

### that reduction of each ton of VOC emissions costs on average $2,301, the cost of switching to low VOC content solvents for parts cleaners is:
$2,301/ton reduced * 871.2 tons/yr = $2.0 million

Other Solvent Cleaning Operations Other solvent cleaning operations is the method of cleaning a surface by physically rubbing it with a material such as a rag, paper, sponge or a cotton swab moistened with a solvent. The total VOC emissions from other solvent cleaning operations used by these facilities are equal to 100% - 8% = 92% of all VOC emissions from cleaning operations:
12,094 tons/yr x 92% =11,126.5 tons/yr

In accordance with the industry information, the average VOC concentration (density) of the solvents used by these facilities is 500 g/liter. If the facilities replace the organic solvent that they are currently using with a cleaning solution that has 50 g/liter VOC content (concentration), the controlled emissions would be as follows:
11,126.5 tons/yr * (50 g/liter/500 g/liter) = 1,112.6 tons/yr

The actual emission reduction from switching to low content VOC material is:
11,126.5 tons/yr

–

1,112.6 tons/yr = 10,014 tons/yr

Using the same EPA assumption as above that a reduction of one ton of VOC emissions saves companies using other solvent cleaning operations -$1,832.5, the cost savings of switching to low VOC content solvents for industrial cleaning operations is:
-$1,832.5/ton reduced * 10,014 tons/yr = - $18.4 million (savings)

This is the maximum amount of cost reduction (benefits) associated with the proposed rule changes, which assume that none of the regulated parties have already made the switch to reduce costs. The actual cost reduction in this scenario is likely to be lower (probably much lower). These savings are

### OSBM Certified 11- 05 -2012 16

derived from the significantly lower cost of recycling material with low VOC content material as opposed to high-VOC materials.

In accordance with the ACA information, application of low-VOC content material for industrial cleaning will increase the material (acetone) usage by approximately 5 tons/yr. The cost of low-VOC content(acetone) material is $500 per ton ( in 2005 dollars) adjusted to $692 (in 2012 dollars). The final savings are:
5 tons * $692 * 139 facilities = $ 48 1,000 per year
This estimation is used for the worst case scenario summary. For industrial cleaning solvents, DAQ estimates that the private sector would incur annual costs of up to $2.5 million, [$0.5 million (acetone usage) + $2.0 million (part cleaners)] and cost-savings of $18.4 million. Combined annual impacts amount to net cost-savings of up to $15.9 million. However, these potential costs and benefits woul d not be evenly distributed, with some facilities incurring net costs and others obtaining net benefits.
These savings are supported by EPA’s study published by the Bay Area AQMD to estimate the cost of compliance for the measures recommended in this CTG. According to these estimates, EPA believes that affected sources may either incur minimal additional costs or realize a savings on a case- by -case basis, depending primarily on facts such as how much they currently spend to operate high-VOC content solvent-based parts cleaners, and the cost of organic solvent disposal. The Bay Area AQMD studies indicate that there is a cost savings associated with replacing high-VOC cleaning materials with low-VOC, water-based cleaning materials.
The DAQ industrial-cleaning estimates were adjusted and reduced from estimations that EPA provided in the CTG

. DAQ used 500 g/liter as the current average VOC concentration (density) of the solvents as provided by ACA for the inks, coatings, adhesives, and resins manufacturing sector, whereas EPA used 900g/liter as the worst case scenario in its example.DAQ is using real data provided by the industry.

Industry representatives identified a concern with the assumption that there would be a similar cost savings resulting from application of the solvent cleaning requirements for the inks-, coatings-, adhesives-, and resins- manufacturing sector related to mitigating factors at potentially affected facilities (discussed in more detail below).

Cleaning of Resin, Coating, Ink, and Adhesive Mixing, Molding, and Application Equipment in Coating, Ink, and Adhesive Manufacturing

Sources that were exempt from the cleaning-solvent requirements under the Bay Area rules, which served as the basis for the cleaning-solvent CTG, were not included in the CTG cost calculations. The current North Carolina rule did not make a distinction regarding applicability of the cleaning-solvent limit to the resin, coating, ink and adhesive manufacturing category. The proposed amendments to 02D .0962 incorporate the underlying exclusion from the 0.42 lb/gal limit for this subset of sources and associated compliance alternatives based on the Bay Area rules.
To estimate the potential cost reduction associated with excluding cleaning-solvent emissions from cleaning of resin, coating, ink, and adhesive mixing, molding, and application equipment in coating,

### OSBM Certified 11- 05 -2012 17

ink, and adhesive manufacturing from the general 0.42 pounds per gallon of VOC content cleaning material limit and establish the 1.67 pounds VOC per gallon limit and other compliance alternatives, DAQ is using cost estimates provided by industry representatives in this analysis.

DAQ initially identified five potentially affected sources in the nonattainment area counties in this sector. Further review determined that: one facility has closed; one facility has moved to South Carolina; one facility has less than five tons per year emissions and already uses acetone which is not considered a VOC relative to ozone formation; one facility produces water-based products; and the remaining facility is outside the boundary of the portion of Iredell county that is part of the NAA and thus is not subject. Given that one of the two remaining facilities in the resins-, inks-, coatings-, and adhesives-manufacturing sector in the current nonattainment area already uses acetone and the other produces water based products, it appears that the cost savings described would not be realized at this time.

Cost estimation for the facilities with the coating, adhesive and printing units. DAQ estimated the number of facilities affected by the amendments to rule .0902 by analyzing data provided by Mooresville Regional Office (MRO) and Mecklenburg County Air Quality local program. MRO regulates 77 facilities with total VOC emissions of 636 tons/year and Mecklenburg County has 73 facilities with total actual VOC emissions of 636 tons/year. These facilities were selected from both databases by cross-referencing the following criteria: (1) facilities with VOC emissions more than 15 lbs/day (2.74 ton/year) and the potential to emit less than 100 tons/year; (2) facilities with the units covered by the CTG.
These facilities are divided in two categories: (1) printing facilities and (2) coating and adhesive facilities, in accordance with EPA recommendations.

Total VOC Emissions from the Affected Facilities Located in Mooresville Region and Mecklenburg County

Among printing facilities there are twenty one (21) offset lithographic and letterpress printing units and one (1) flexible package printing unit. Among coating and adhesive facilities there are 128 units with different types of coatings and adhesive applications. Accordingly, there is necessarily some uncertainty in material estimation in any prediction of costs and emission impacts associated with the fact that the CTG recommendations are based on multiple EPA assumptions.

Cost estimation for lithographic printing and letterpress printing units DAQ has chosen to adopt the CTG approach to estimate cost of compliance with the RACT requirements for the offset lithographic printing and letterpress printing units. These recommendations are based on EPA model plant analysis in which it evaluated VOC emissions associated with different kinds of printing processes, the VOC emission reduction capabilities of

### OSBM Certified 11- 05 -2012 18

various control options, and the costs of such controls. The model plants were developed to represent a range of sizes and emissions.

Because of the similarities between offset lithographic printing and letterpress printing, in terms of the nature of the processes at issue, the sources of VOC emissions and available control approaches, EPA made an assumption that the cost-effectiveness for control of VOC from heatset inks and control of VOC from cleaning materials apply equally to the letterpress printing industry. Finally, EPA came up with four different numbers for total annual cost of control per facility for four different types of model plan ts

. 10



### To estimate cost of compliance with the RACT requirements for printing facilities located in the 8- hour Charlotte-Gastonia-Rock Hill ozone area, DAQ averaged the costs of four different types of EPA’s model plants , which equaled $248,525 per facility.

There are 21 offset lithographic printing and letterpress printing units and one facility with three flexible printing units in the ozone area.

DAQ calculated the cost for 21 lithographic printing and letterpress printing facilities located in the 1997 8-hour Charlotte-Gastonia-Rock Hill ozone area as:
21 facilities * $248,525= $5.2 million

The baseline is the current rule, which requires daily recordkeeping for all printing facilities to assure compliance with the 15 lbs-per-day limit. Currently, no printing facilities must comply with current recordkeeping rules, as none have a potential to emit more than 100 tons of VOCs per year. The proposed amendments to 02D .0961 would allow an equivalent level of three tons per 12 -consecutive month rolling period

. The change allows printing facilities to avoid unnecessary daily recordkeeping costs. In the worst-case event (if EPA fails to re-designate the area as a maintenance area), under the existing rule, all printing facilities would have to maintain dail y records to assure 15 lbs-per-day limit.

Printing Industries of America illustrated the financial impracticability for printing operations by estimating the average cost of implementing a daily recordkeeping system to meet the requirements of the current rule. The estimated average costs are associated with daily recordkeeping for an operation with three sheetfed offset lithographic presses. The example is for a 6-color 40 inch, 4-color 26 inch, and a 2-color 20 inch press, which are common in commercial printing operation. The full cost, based on 2008 data, includes wages, equipment, and all overhead with the assumption that the presses are running at an 85-percent utilization rate, which is the theoretical maximum utilization rate. Most facilities will use a 70 percent utilization rate for their budgeting.

Average of 1 hour of lost production time per day for each press:
Press 001 (6-color) - $505.00/hour Press 002 (4-color) - $264.00/hour Press 003 (2-color) - $ 77.00 /hour

- 002 2006/09

### OSBM Certified 11- 05 -2012 19

Total: $846.00/hour

Average total baseline monthly cost associated with daily recordkeeping:
$ 846 (Total Per Day Lost Production and Press Operator Costs) x 20 (Average Work Days Per Month) $16,920 (Average Total Monthly Cost)

The baseline cost is zero because there are no facilities that are currently subject to the daily recordkeeping requirements in the current rules.

Under the proposed monthly recordkeeping rule, affected facilities would bear these costs on a once-per-month basis, leading to a total cost of:
$846 (monthly recordkeeping costs) x 21 (number of the affected facilities) x 12 (months) = $213,000

Compared to an alternative baseline of daily recordkeeping for printing facilities, the annual savings of switching the average facility from daily to monthly recordkeeping are estimated to be:
$4.3 million -$213,000 = $4.1 million (savings relative to a n alternative baseline of daily recordkeeping for all affected printing facilities)

Relative to the current

baseline for lithographic printing and letterpress printing facilities, the proposed rules would impose $5.4 million in additional costs ($5.2 million for RACT compliance costs plus $0.2 million for monthly recordkeeping).

Cost estimation for flexible printing units Due to insufficient information about flexible printing units in the database, DAQ has chosen to adopt the EPA-recommended algorithm to estimate the cost for the flexible package printing units. The cost is for a fixed-bed catalytic oxidizer with 95-percent destruction efficiency, which is the equipment likely to be used to control emissions to comply with the RACT requirements at a typical or average facility with individual presses for flexographic printing. EPA estimated the total capital investment (TCI) for the fixed-bed catalytic oxidizer as $471,603 per press. 11 

### The database indicated that only one facility with three flexible printing units is affected by these amendments. TCI for three presses is:
$471,603 * 3 = $1.4 million (one-time capital investment)

The annualized capital recovery factor of 0.10979 was based on 7 percent interest rate and 15 years of useful life. The annualized capital cost is:
$1.4 million * 0.10979 = $155,000
Finally, EPA estimated the total annual operating cost (TAC) for the high-end scenario as $131,385 for each press per year and for the low-end scenario as $121,704 for each press per year. In accordance with EPA recommendations, the low end scenario is chosen for the solvent use rate of

11 Control Techniques Guidelines for Flexible Package Printing EPA- 453/R

- 06 -003 2006/09

### OSBM Certified 11- 05 -2012 20

25 ton/yr and the high end is is chosen for the solvent use rate of 100 ton/yr

. Consequently, the high end TAC cost for the three presses is:
$131,385 * 3 = $394,000 per year

The low end TAC for the three presses is:
$121,704 * 3 = $365,000 per year

The total annual cost is: $365,000 + $155,000 = $520,000 low end, end $394,000 + $155,000 = $549,000 high end
The high estimate of $549,000 is used for the worst case scenario summary.

Cost estimation for coating and adhesive units This cost estimation is based on data provided by the MRO. It includes information on VOC content in material that the coating and adhesive facilities use to comply with the current air quality regulations. DAQ made an assumption that the facilities located in Mecklenburg County use the same VOC content material for similar production units as the facilities located in MRO

. To calculate the emission reduction, DAQ estimated the average VOC concentration limits required to comply with RACT requirements by interpolating VOC concentrations limits established for the RACT compliance and the current VOC concentrations by interpolating the data presented by MRO and Mecklenburg County. The reduction is calculated in accordance with EPA recommendations 12

. 

### The results are presented in the Table below.

VOC Concentration Limits Reduction Required to Comply with the RACT Requirements Units Current concentration of VOC RACT requirements Reduction Coating 0.17 lb/gal 0. 0 7 lb/gal 574 tons/yr

The emission level required to comply with RACT is calculated as the ratio between projected VOC concentrations needed to comply with the RACT requirements and current VOC concentrations multiplied by the current emission level from coating and adhesive units:
978 tons/yr 13 

### * 0.07 lb/gal / 0.17 lb/gal = 402 tons/yr

Emission reduction is calculated as the difference between the current (table on page 15) and required emission level:
978 tons/yr

–

402 tons/yr = 574 tons/yr

EPA estimated that the cost effectiveness to comply with RACT requirements for coating and adhesive units is in the range between 0 and $3,596 per ton of reduction depending on coating operations. DAQ analyzed data provided by the MRO and Mecklenburg County. It included information about specific types of coating operations for each facility. EPA cost effectiveness data was then applied to each affected facility with specific coating operation. The results indicat ed that most likely the affected facilities with coating and adhesive units have the range between $553 and $2,213.

The cost of emission reduction for the affected facilities with coating and adhesive units (including facilities with local and federal funds) is between:
574 tons/yr * $553 =$317,000 low end, and 574 tons/yr * $2,213 = $1.3 million high end

The high estimate of $1 .3 million is used for the worst case scenario summary.

All estimations are made in accordance with Control Techniques Guidelines for Industrial Cleaning Solvents 14 

### recommendations.

Actual costs could be lower. The current section .0900 provides a couple of simple, low-cost options for facilities that would need to achieve compliance with these new RACT requirements. For instance, if a facility owner or operator can demonstrate that an alternative operational or equipment control is superior to the required control, they may petition the director to allow the use of alternative controls for VOC emissions reduction. This option may be useful for facilities with flexibility to switch to an alternative operational schedule or to change production levels. For example, a facility may choose to change its operational schedule to avoid daily VOC emissions above 15 lb/day, or it may change production to lower VOC emissions.

Alternative controls for RACT also can be an option for facilities that demonstrate compliance with the rules in Section .0900 would be technologically or economically infeasible. Such facilities may petition the Director to allow the use of alternative operational or equipment controls for the reduction of volatile organic compound emissions. This option may be especially attractive to facilities with high total capital investments (TCI). EPA guidance 15 

### indicates that a facility may choose an alternative, less expensive than add-on control method for RACT compliance.

Local Government Of the 128 total coating and adhesives facilities, DAQ identified three facilities operated by local governments. The cost of compliance with the RACT requirements for these facilities is calculated separately in accordance with the state budget manual.

Taken together, the three facilities operated by local funds have the potential to emit 29.9 tons of VOC per year (27,125 kg/yr). The cost of emission reduction is calculated using the same algorithm as the private facilities with coating and adhesive units.

Local government facilities:

14 Control Techniques Guidelines for Miscellaneous Metal and Plastic Parts Coatings 15 Guidance Document for Correcting Common VOC & Other Rule

### OSBM Certified 11- 05 -2012 22

29.84 tons/yr * 0.07lb/gal/0.17lb/gal = 12.29 tons/yr 29.84 tons/yr -12.29 tons/yr = 17.6 tons/yr 17.6 tons/yr * $553 = $9,7 00 low end, and 17.6 tons/yr * $2,213= $39,000 high end
The high estimate of $39,000 is used for the worst case scenario summary.

Federal Government DAQ identified one coating and adhesives facility operated by a federal entity. The federal facility has potential to emit 2.8 tons of VOC per year. The cost of emission reduction is calculated using the

sa me algorithm as the private facilities with coating and adhesive units.

Federal government facility:
2.8 tons/yr * 0.07 lb/gal/0.17 lb/gal = 1.15 tons/yr 2.8 tons/yr - 1.15 tons/yr = 1.65 tons/yr
1.65 tons/yr * $553 = $9 00 low end and 1.65 tons/yr * $2,213 = $3,700 high end
The high estimate of $3,700 is used for the worst case scenario summary.

North Carolina Division of Air Quality and Mecklenburg County Air Quality Program In accordance with Rule 15A NCAC 02Q .0203, Permit and Application Fees, no additional permit application fees will be required for the affected facilities after these amendments become effective. While staff would have to spend some time to incorporate appropriate permit conditions, since all these facilities are already permitted and are subject to compliance inspections, changes in permit writing procedures or facility inspection schedule caused by these amendments are insignificant. No additional DAQ staff would be anticipated, nor would existing staff be expected to undertake any significant additional activities

. Consequently, DAQ and Mecklenburg County Air Quality Program cost/savings for implementing these amendments are negligible.

General Public The primary benefit of this set of amendments under the expected scenario is to meet the requirements of the CAA and ensure approval of the VOC RACT State Implementation Plan (SIP) by EPA. The EPA approval can mitigate the consequences of a SIP deficiency including possible disapproval and, lacking correction within required timeframes, implementation of a federal program, and if not eventually corrected, potential sanctions on highway transportation funding. In addition, without the amendments, EPA would not be able to approve the re -designation and maintenance plan for the Charlotte-Gastonia-Rock Hill 1997 nonattainment area, and requirements for moderate nonattainment areas such as nonattainment new source review would continue to apply even though monitoring data show compliance with the 1997 8-hour ozone standard.

These VOC RACT requirements are unlikely to have a substantial impact on atmospheric ozone concentrations because in North Carolina most VOC emissions come from biogenic sources and the state, like much of the southeast, is in a NOx-limited environment with respect to ozone formation

. However, although not their direct purpose, the proposed rule changes (if implemented under one

### OSBM Certified 11- 05 -2012 23

of the unexpected scenarios) may provide secondary benefits for manufacturing workers who may be exposed to fewer or less toxic chemicals depending on what is currently used if solvent switching is the chosen compliance mechanism. Air toxics are a group of chemical air contaminants, defined by EPA, that have been associated with wide-ranging and significant adverse health effects, including cancer and other serious health effects such as reproductive effects or birth defects, or adverse environmental effects.

The reduction of toxics in manufacturing facilities or in production practices that reduce or eliminate the use and emissions of toxic materials into the environment is generally preferable to add-on controls. As a possible secondary benefit, these proposed rule changes may lessen potential worker exposure to hazardous air pollutants in printing, solvent coatings and cleaning operations.

Summary of Costs and Benefits Under Unlikely Scenario
If (1) the maintenance area later fails to meet the 1997 standard and (2) the Division of Air Quality Director implements the proposed amendments as part of the contingency plan to bring the area back into attainment, there would be potential impacts. Under the worst-case scenario, DAQ estimates private industry would incur annual costs of up to $9. 7 million, and cost-savings of up to $18.4 million. Combined annual impacts amount to net cost-savings of up to $8.8 million (with potential costs and benefits attributed to different entities), and up to $28 million when aggregated

. There are no impacts on the expenditure of State funds. The North Carolina Division of Air Quality would not experience new costs associated with these proposed rule changes. Local governments operate three coating and adhesive facilities and these may incur costs up to $39,000. The federal government operates one coating and adhesive facility that may incur costs up to $3,600 to comply with the new regulations.
These cost estimations were made for the worst-case scenario assuming that: (1) all VOC emissions from affected facilities are coming only from sources of VOC emissions covered by control techniques guidelines (CTG); and (2) all affected facilities are currently not meeting RACT requirements. The annual impacts to state, local and federal government, and the private sector, are summarized in the following table.

To the extent that facilities have already reduced the VOC content of the solvents and coatings they use and have already achieved levels in the CTGs, then no additional reductions would be needed and the costs and benefits estimated in this assessment wou ld be much higher than would actually be realized, resulting in an overestimate of the impact.

The general public may benefit from cleaner air, and workers in facilities that use VOC materials may be exposed to fewer toxics if solvent switching is the compliance mechanism of choice. These benefits are not quantified because they are not expected to occur under the most likely scenario

. Sources of Uncertainty in Estimates The estimation of the emission reductions associated with the selected control strategies described above is subject to important limitations and uncertainties. There are several sources of uncertainty that may affect the results of this analysis.

Due to DAQ lacking a comprehensive database on the facilities that use the industrial cleaning solvents for cleaning operations, DAQ estimated the cost of RACT compliance for the facilities with industrial cleaning solvents by using the number of affected facilities and the current level of VOC emissions from these facilities estimated by EPA and obtained from Control Techniques Guidelines for Industrial Cleaning Solvents

. 16 

### EPA noted that this information was determined by first assigning the VOC emissions from solvent cleaning operations at each facility from 2002 National Emissions Inventory (NEI) database to one of two general groups: parts cleaners, or other solvent cleaning operations. The parts cleaner subgroup included emissions from all source classification codes (SCCs) with a “degreasing” or cold solvent cleaning/stripping classification.

The EPA estimation that DAQ used for the cost estimations is based on compliance with the RACT requirements that are recommended by Alternative Control Techniques (ACT) Document issued in February 1994. EPA simply established the baseline as a VOC emission levels which meet RACT requirements recommended by the ACT Document issued in February 1994 and calculated the

16 Control Techniques Guidelines for Industrial Cleaning Solvents EPA-453/R- 06 -001, 2006/09

### OSBM Certified 11- 05 -2012 25

emission reduction as a difference between RACT requirements recommended by the ACT issued in 1994 and the CTG issued in 2006. While using this difference for the cost reduction calculation, DAQ found that the 500 g/liter average VOC concentration (density) of the solvents for the year 2012 provided by American Coating Association is more reliable number than the 900 g/liter figure used by EPA in its example cost estimation as the worst-case scenario in 2006 when CTG was issued. DAQ is using the data provided by the industry.

The second source of uncertainty is completeness of information on VOC units and VOC concentrations that affected facilities are using obtained from MRO and Mecklenburg County Air Quality local program. In this situation, DAQ made several assumptions described above based on staff members’ best judgment and engineering experience to quantify the impacts in these areas. There is also uncertainty regarding what share of facilities that could save money by using low-VOC content materials have already converted to the lower-cost materials. If a significant number of those facilities ha ve made the transition, then the potential cost savings would be substantially lower.
As a general matter, DAQ selected the best-available information from available databases and EPA’s CTGs and has set up what it believes is the most reasonable framework for analyzing the cost, potential emission changes, and other impacts of regulatory controls.

VII. CONCLUSION.
The DAQ is required, under provisions of CAA Section 172(c)(1), to submit a SIP that will lead to attainment of the NAAQS for ozone. Section 182(b)(2) of the CAA also provides that North Carolina must revise its ozone SIP to include RACT for each category of VOC sources covered by any CTG document issued after November 15, 1990, and prior to the date of attainment.
The proposed rule amendments are needed in order for the state’s SIP to meet the requirements of the CAA and receive approval from EPA. North Carolina’s current RACT rule, 02D .0902, applies only to facilities that have the potential to emit (PTE) greater than or equal to 100 tons of volatile organic compounds (VOC) per year located in the Charlotte-Gastonia-Rock Hill, NC 8-hour Moderate Ozone Nonattainment Area. The proposed amendments bring North Carolina into compliance with federal law by extending this applicability to all VOC sources covered by any CTG in the nonattainment area. This proposal also amends rule 02D .0909 to clarify compliance schedules for the newly affected facilities, makes conforming changes to 02D .0951, and a corresponding update to related language in 02Q .0102. In response to comments from industry associations on the existing rules, the amendments to 02D .0903, .0961, and .0962 clarify language and provide compliance alternatives consistent with the CTGs.

The Division of Air Quality anticipates no direct costs to result from this rulemaking. In extreme circumstances, failure to adopt these rules could lead to more federal regulation and, eventually, potential sanctions on highway transportation funding.

The proposed rules would not result in any immediate costs for regulated facilities. The amendments do not require additional permitting or inspection of additional facilities and consequently, they would have no economic impact on NCDAQ and Mecklenburg County (Land Use and Environmental Services Agency). There are no economic impacts related to permitting for NC Department of Transportation projects.

### OSBM Certified 11- 05 -2012 26

If (1) the maintenance area later fails to meet the 1997 standard and (2) the Division of Air Quality Director implements the proposed amendments as part of the contingency plan to bring the area back into attainment, there would be potential impacts. This scenario is highly unlikely because the current state of the science regarding atmospheric formation of ground level ozone indicates implementing these rules would do little to improve ozone levels.

Under the worst-case scenario, DAQ estimates private industry would incur annual costs of up to $9. 7 million, and cost-savings of $18.4 million. Combined annual impacts amount to net cost-savings of up to $8.8 million (with potential costs and benefits attributed to different entities), and up to $28 million when aggregated

. There are no impacts on the expenditure of State funds. The North Carolina Division of Air Quality would not experience new costs associated with these proposed rule changes. There would be no additional permitting or inspection activity and consequently, this scenario would have no economic impact on NCDAQ and Mecklenburg County (Land Use and Environmental Services Agency). Local governments operate three coating and adhesive facilities and these may incur costs up to $39,000. The federal government operates one coating and adhesive facility that may incur costs up to $3,600 to comply with the new regulations.
