The hearing will address amendments to 7 DE Admin. Code 1130 to remove the emergency affirmative defense provisions and references.

7 DE Admin. Code 1130 is based on Title 40 of the Code of Federal Regulations (CFR) Part 70, which outlines requirements for state operating permit programs.  Subsection 6.7 of 1130 includes guidance on claiming affirmative defenses for emission exceedances for emergencies.

On July 21, 2023, the Environmental Protection Agency issued a final rule (88 FR 47029), which removed all emergency affirmative defense provisions for state and federal operating permit programs in 40 CFR Part 70.6(g) and 71.6(g).

To maintain consistency with the current federal requirements, the Division is proposing to remove the affirmative defense provisions from 7 DE Admin. Code 1130.

Additional amendments correct a typographical error (7 DE Admin. Code 1130, Section 8.0 of Appendix A “Insignificant Activities”). This correction is not substantive and does not change the intent or purpose of the regulation.

The proposed amendments may be inspected online starting April 1, 2024 at, or in-person, by appointment only, by contacting Taylor Englert by phone at 302-323-4542 or by email at

The Department will accept public comment through May 10, 2024. Comments will be accepted in written form via email to, using the online form at, or by U.S. mail to the address on this page.
