HB 407 Delaware House · 153rd General Assembly (2025-2026)

AN ACT TO AMEND TITLES 7 AND 30 OF THE DELAWARE CODE RELATING TO THE DELAWARE HAZARDOUS SUBSTANCES CLEANUP ACT AND THE REALTY TRANSFER TAX.

Summary
House Substitute No. 1 for House Bill No. 407, like the original, does all of the following: clarifies the ability of the Department of Natural Resources and Environmental Control (DNREC) to respond to emergent situations, expands the jurisdiction from which DNREC may file to recover costs, and makes certain changes to amounts deposited into the Hazardous Substance Cleanup Act Fund. Section 1 provides definitions for “Abate,” “Emergency,” and “Removal Action.” Section 2 clarifies the ability of the Secretary or their authorized employees or agents to determine if an emergency exists and take immediate action to abate the emergency without obtaining public comment. Section 3 allows the Department to authorize removal actions to address releases without first obtaining public comment, and to incorporate the removal action into any proposed plan of remedial action by DNREC. Section 4 expands the jurisdiction of the courts which DNREC may bring enforcement actions and recover costs. Section 5 increases the civil penalty for each fraudulent act from up to $10,000 to $40,000. Section 6 extends the end date from January 1, 2029, to January 1, 2037, for monies to be deposited into the Hazardous Substance Cleanup Act Fund (the “Fund.”) Section 7 provides the effective date of this legislation. This Substitute differs from the original House Bill No. 407 in that it removes references to the realty transfer tax.

HA 1 to HS 1 for HB 407 Bill Text · 10 edits
MAJOR
HB 407 transitions from a minor House Amendment (deleting redundant lines) to a full House Substitute that substantially rewrites the Delaware Hazardous Substances Cleanup Act provisions. The substitute adds new definitions, expands DNREC's emergency response and enforcement authority, increases fraud penalties fourfold, extends the petroleum gross receipts tax funding the cleanup fund through 2037, and requires one-third of fund deposits to support a Brownfields Development Program after 2026.
DEFINITION

New definitions added for 'Abate,' 'Emergency,' and 'Removal Action' in Section 9103 of Title 7.

ENFORCEMENT

Emergency entry provision restructured to require both that an emergency exists AND that the operator is unwilling or unable to act, before DNREC can enter without a court order.

New subsection 9107(h) allows the Secretary to authorize a removal action without first obtaining public comment, provided it is incorporated into any proposed plan of remedial action.

Enforcement actions under Section 9109 can now be brought in 'a court of competent jurisdiction' rather than only Superior Court, broadening where DNREC can file to recover costs and natural resource damages.

Civil penalty for fraud in settlement agreements or certification applications increased from up to $10,000 to up to $40,000 per fraudulent act.

REQUIREMENT

Consent decrees under Section 9107(b) must now be filed with either Superior Court or Court of Chancery (previously only Superior Court), and the Secretary must allow at least 20 days for public comment before entry.

FISCAL

Section 9109(e) now explicitly includes attorney's fees and employee time as recoverable remedial costs.

The end date for the additional petroleum gross receipts tax funding the Hazardous Substance Cleanup Fund is extended from January 1, 2029 to January 1, 2037.

New requirement that for taxable periods beginning after December 31, 2026 through December 31, 2036, one-third of moneys deposited into the Fund must be dedicated to implementing the Brownfields Development Program.

SCOPE

References to the realty transfer tax are removed from the bill (they were present in the original House Bill).
