DATE:	 December 12,2010 

I. Background: 

A public hearing was held on Wednesday, June 2, 2010, at 6:00 p.m. at the 

Department of Natural Resources and Environmental Control ("DNREC", 

"Department"), 89 Kings Highway, Dover, Delaware to receive comment on proposed 

amendments to 7 DE Admin. Code 1124, Control of Volatile Organic Compound 

Emissions: Section 8.0, "Handling, Storage, and Disposal of Volatile Organic 

Compounds"; Section 13.0, "Automobile and Light-Duty Truck Coating Operations"; 

Section 16.0, "Paper Coating"; Section 23.0, "Coating of Flat Wood Paneling"; Section 

37.0, "Graphic Art Systems"; and Section 45.0, "Industrial Cleaning Solvents". The 

purpose of these proposed amendments is to conform to new Control Techniques 

Guidelines (CTG) issued by the U.S. Environmental Protection Agency (EPA). 

•
 
It should be noted that this regulatory promulgation initially included additional 

proposed amendments to be made to 7 DE Admin. Code 1124, at Section 47.0, "Offset 

Lithographic Printing". The Department has, at this time, formally withdrawn the 

proposed amendments to Section 47.0, as substantive changes to the same were 

necessitated as a result of the public comment received by the Department in this matter. 

The Department will be addressing its revised proposed amendments to Section 47.0 of 7 

DE Admin. Code 1124 in a separate regulatory promulgation in the immediate future. 

Section 182(b)(2) of the Clean Air Act (CAA) requires all ozone non-attainment 

areas, including Delaware, to update relevant regulations for Reasonably Available 

Control Technology (RACn controls for emission sources covered in EPA's CTG, and 

to submit the regulations to EPA as State Implementation Plain (SIP) revisions. The 

aforementioned six sections of 7 DE Admin. Code 1124, as addressed within these 

proposed regulation amendments, were originally developed in the early 1990's based on 

EPA's CTGs. From September 2006 to September 2008, the EPA updated relevant 

CTGs to reflect technology developments or to expand Volatile Organic Compound 

("VOC") emission controls. The aforementioned proposed revisions reflect DNREC's 

incorporation ofthe recent CTG information into existing Delaware Regulation 1124. 

The following is a brief summary of the revisions to each of the affected sections 

of existing Delaware Regulation 1124: 

Section 8.0: Handling. Storage and Disposal ofVOC: 

For this section, the proposed revision adds a new VOC content limit applicable 

for cleaning solvents generally used in facilities regulated under Regulation 1124, adds a 

new definition section. and updates the existing work practice standards according to the 

2
 
new CTGs. The revision to Section 8.0 is based primarily on the Industrial Cleaning 

Solvents CTG, however, it does include several work practice recommendations 

collectively from other new EPA CTGs that have triggered the revisions of other sections 

being addressed at this time as well. 

Section 13.0: Automobile and Light-Duty Truck Coating Operations: 

The current Section 13.0 sets up VOC limits in coating materials used in new 

automobile and light-duty truck coating operations. This revision has more stringent 

VOC limits for these coating operations to reflect eTG recommendations. 

Section 16.0: Paper Coating: 

The current Section 16.0 has a VOC emission control standard for paper coating 

units. This revision expands the regulated scope from paper coating until only to "paper, 

. film and foil coating units". 

Section 23.0: Coating of Flat Wood Paneling: 

The current Section 23 has three (3) different VOC control standards for coating 

processes of three (3) different flat wood paneling products: printed interior panels, 

natural finish panels, and Class II finish panels. This revision adds tileboard panels and 

exterior sidings to the related scope, and has a uniform and more stringent standard for all 

five (5) paneling products. 

Section 37.0: Graphic Arts Systems: 

The current Section 37.0 applies to packaging printing presses. This revision adds 

provisions for a special group of packaging printing presses, to wit: flexible packaging 

printing presses, and establishes efficiency requirements for control systems to be 

installed On the flexible packaging printing presses. 

3 
Section 45.0: Industrial Cleaning Solvents: 

The current Section 45.0 has application standards for industrial use of organic 

cleaning solvents. 1bis revision clarifies that the requirements of Section 45.0 are 

triggered based on a limit of"VOC emissions" rather than "solvent used". 

It should be noted that no members of the public attended the hearing on June 2, 

2010, nor was any public comment received with regard to the above-referenced six (6) 

sections of 7 DE Admin. Code 1124. Proper notice of the hearing was provided as 

required by law. 

II. Summary of Hearing Record: 

At the time of the hearing on June 2, 2010, Gene Pettingill of the Department's 

Division of Air Quality Management (AQM) offered the Department's seven (7) exhibits 

pertaining to these proposed amendments, and this Hearing Officer entered them into the 

formal hearing record developed in this matter. Included within those Departmental 

exhibits were copies of the Start Action Notices for this promulgation, copies of the legal 

notices regarding the holding of this public hearing on June 2, 20 I0, a copy of the 

Control Techniques Guidelines (CTG) from the EPA which triggered the revisions 

addressed within this promulgation, copies of related reference rules upon which the 

Department relied in the drafting ofthese proposed amendments, and copies ofthe actual 

proposed amendments to the aforementioned sections 7 DE Admin. Code 1124. 

Also contained within the Department's exhibits were copies of the two public 

comments received with respect to the proposed amendments on Section 47.0 of existing 

Regulation 1124. As noted above, changes to Section 47.0 were originally proposed and 

included by the Department in this promulgation; however, the same were subsequently 

4
 
withdrawn by the Department, and will be addressed in a separate, future promulgation. 

No other comments were received by the Department concerning this malter. 

For the Secretary's review, and in order for the Secretary to gain a thorough 

understanding of this proposed promulgation, copies of the above-referenced proposed 

amendments are attached hereto as Appendix "A", and the same are expressly 

incorporated into this Hearing Officer's Report. 

rt should be noted that the Department adhered to all appropriate Delaware 

statutes and the regulatory development process in this malter, and that the Department 

has met the required public notice obligations regarding these proposed amendments. It 

should also be noted that the Department has reviewed this proposed amendment in the 

light of the Regulatory Flexibility Act, and believes the same to be lawful, feasible and 

desirable, and that the recommendations as proposed should be applicable to all Delaware 

citizens equally. 

Ill. Conclusions and Recommendations: 

Based on the record developed in this malter, I conclude that the Department has 

provided appropriate reasoning regarding the need for these proposed amendments to 7 

DE Admin. Code 1124, Control of Volatile Organic Compound Emissions: Section 8.0, 

"Handling, Storage, and Disposal of Volatile Organic Compounds"; Section 13 .0, 

"Automobile and Light-Duty Truck Coating Operations"; Section 16.0, "Paper Coating"; 

Section 23.0, "Coating of Flat Wood Paneling"; Section 37.0, "Graphic Art Systems"; 

and Section 45.0, "Industrial Cleaning Solvents". I also recommend the adoption of the 

proposed regulatory amendments, based upon the reasoning provided by AQM. 

5
 
Accordingly, I recommend promulgation ofthese proposed amendments in the customary 

manner provided by law.
