Under the authority vested in the Secretary of the Department of Natural Resources and Environmental Control (“Department” or “DNREC”) the following findings, reasons and conclusions are entered as an Order of the Secretary in the above-referenced rulemaking proceeding.

Background and Procedural History

This Order considers proposed regulation amendments to 7 DE Admin. Code 1124, Control of Volatile Organic Compound Emissions: Section 2.0, “Definitions”; Section 12.0, “Surface Coating of Plastic Parts”; Section 19.0, “Coating of Metal Furniture”; Section 20.0, “Coating of Large Appliances”; and Section 22.0, “Coating of Miscellaneous Metal Parts. The purpose of these proposed amendments is to conform to new Control Techniques Guidelines (CTG) issued by the U.S. Environmental Protection Agency (EPA).

The Department’s Air Quality Management (AQM) Section of the Division of Air and Waste Management (DAWM) commenced the regulatory development process with Start Action Notice 2009-10 through 2009-13. The Department published the proposed regulatory amendments in the December 1, 2009 Delaware Register of Regulations and held a public hearing on January 5, 2010. The Department’s presiding hearing officer, Lisa A. Vest, prepared a Hearing Officer’s Report dated February 26, 2010 (Report). The Report recommends certain findings and the adoption of the proposed Amendments as attached to the Report as Appendix A.

Findings and Discussion

I find that the proposed Amendments are well-supported by the record developed by the Department, and adopt the Report to the extent it is consistent with this Order. The Department’s experts in AQM developed the record and drafted the proposed Amendments. The Department received public comments, as noted in the Report, and considered and responded to all timely and relevant public comments in making its determination.

I find that the Department’s experts in the AQM Section of the DAWM fully developed the record to support adoption of these Amendments. With the adoption of these regulatory amendments, Delaware will have the Department’s regulations conform to EPA’s regulations, as required by the Clean Air Act.

In conclusion, the following findings and conclusions are entered:

1.) The Department has jurisdiction under its statutory authority to issue an Order adopting these proposed Amendments as final;

2.) The Department provided adequate public notice of the proposed Amendments, and provided the public with an adequate opportunity to comment on the proposed Amendments, including at a public hearing;

3.) The Department held a public hearing on January 5, 2010 on the proposed Amendments in order to consider public comments before making any final decision, and fully considered and responded to all timely and relevant comments received from the regulated community concerning this matter;

4.) The Department’s Hearing Officer’s Report, including its recommended record and the recommended Amendments as set forth in Appendix A, are adopted to provide additional reasons and findings for this Order;

5.) The recommended Amendments do not reflect any substantive changes from the proposed regulation Amendments as published in the December 1, 2009, Delaware Register of Regulations;

6.) The recommended Amendments should be adopted as final regulation Amendments because (1) Delaware will be enabled to conform to new CTG as issued by the EPA; (2) the Department’s revisions to 7 DE Admin. Code 1124 will reduce the VOC contents of currently regulated coatings, regulate additional coating categories, require the use of coating application equipment that provides for high transfer efficiency, and require that clean-up solvent emissions be included in regulatory applicability determinations; and (3) the regulation amendments are well supported by documents in the record; and that

7.) The Department shall submit this Order approving the final regulation to the Delaware Register of Regulations for publication in its next available issue, and provide such other notice as the law and regulation require and the Department determines is appropriate.
