Division of Air and Waste Management

Statutory Authority: 7 Delaware Code, Chapter 60; (7 Del.C., Ch. 60)

7 DE Admin. Code 1124

PROPOSED

PUBLIC NOTICE

1124 Control of Volatile Organic Compound Emissions, Section 11

1. Title of the Regulation:

Amendments to Regulation 1124 Control of Volatile Organic Compounds, Section 11.0 Mobile Equipment Repair and Refinishing”.

2. Brief Synopsis of the Subject, Substance and Issues:

The Department proposes to revise Section 11.0 of 7 DE Admin. Code to require lower volatile organic compound (VOC) content of the coatings and cleaning solvents used in the refinishing of mobile equipment, primarily automobiles, in order to lower VOC emissions, a precursor to the formation of ground-level ozone. The Ozone Transport Commissions (OTC), as an aid to member states in this effort, developed a model rule for mobile equipment refinishing based upon a California rule. Almost all OTC states plan to adopt some form of this model rule. We anticipate a VOC emission reduction of about 300 tons per year.

3. Possible Terms of the Agency Action:

None.

4. Statutory Basis or Legal Authority to Act:

7 Delaware Code, Chapter 60.

5. Other Regulations that May be Affected by the Proposal:

None.

6. Notice of Public Comment:

There will be a hearing on these proposed amendments on Thursday, June 10, 2010 beginning at 6pm in the Richardson & Robbins Auditorium. Interested parties may submit comments in writing to Ronald Amirikian, Air Quality Management Section, 156 South State Street, Dover, DE 19901 and/or statements and testimony may be presented either orally or in writing at the public hearing.
