AN ACT TO AMEND TITLE 11 OF THE DELAWARE CODE RELATING TO OFFENSES INVOLVING PUBLIC INDECENCY.

Under current Delaware law, a minor cannot be guilty of the crime of prostitution under § 1342 of Title 11. This Act removes references to minors engaging in prostitution and being prostituted in favor of using the term "exploited" or “exploitation”, which is defined to mean acts by a minor that would constitute prostitution under § 1342(a) of Title 11 if that minor were 18 years old or older. This change is twofold. (1) It creates a separate term to refer to the exploitation of a minor since minors cannot be guilty of prostitution and prostitution is not otherwise defined outside of the offense in § 1342(a) of Title 11, which excludes minors; and (2) Recognizes a growing trend nationally and internationally to remove language that misleadingly implies that children are able to consent to, and participate in, prostitution. The Interagency Working Group on Sexual Exploitation of Children, comprised of representatives from the United Nations, INTERPOL, and organizations working to end the sexual exploitation of children, published a manual containing terminology guidelines for the protection of children from sexual exploitation and sexual abuse. While there is no single recommended term, attempts should be made to avoid stigmatizing a child and suggesting that the child had culpability in any acts undertaken. Sections 8 through 11 of this Act update internal references elsewhere in the Code to account for the addition of subsection designations in §§ 1352 and 1353. Sections 12 through 13 of this Act add the definition of “illicit massage establishment” from House Bill 409 and update it to account for the change in terminology that this Act makes. This addition of and update to the definition of “illicit massage establishment” only occurs if House Bill No. 409 is enacted. This Act also makes technical corrections to conform existing law to the standards of the Delaware Legislative Drafting Manual.

AN ACT TO AMEND TITLE 3 OF THE DELAWARE CODE RELATING TO THE DELAWARE FARM TO COMMUNITY PROGRAM.

This Act codifies the Delaware Farm and Food Council’s Farm to Community Program as a state-led initiative called the Delaware Farm to Community Program. The Farm to Community Program launched in 2023 under the United States Department of Agriculture’s (USDA) Local Food Purchase Assistance Cooperative Agreement (LFPA). In 2 ½ growing seasons, the Farm to Community Program has effectively expanded the purchasing power of community outlets to procure local food products from local farmers and distribute the food products to individuals in need or facing food insecurity in Delaware’s urban and rural communities. Through this model, currently, 31 local farmers supply more than 100 varieties of fruits, vegetables, meats, and dairy products to 9 community outlets that serve 105 food distribution sites. The USDA canceled LFPA funding in 2025. Codifying the Farm to Community Program ensures continuity, strengthens Delaware’s food system infrastructure, increases availability of fresh and healthy seasonal foods, and increases the economic viability of local farmers, particularly small and medium-scale farmers.

AN ACT PROPOSING AN AMENDMENT TO ARTICLE V OF THE DELAWARE CONSTITUTION RELATING TO ELECTIONS AND VOTING.

This Act is the first leg of a constitutional amendment that would require that only natural persons be allowed to vote in any election in this State, and forbid corporations and other artificial entities from voting in such elections. This Act requires a greater than majority vote for passage because § 1 of Article XVI of the Delaware Constitution requires the affirmative vote of two-thirds of the members elected to each house of the General Assembly to amend the Delaware Constitution. In addition, as the first leg of a constitutional amendment, the next General Assembly must pass an act concurring with this Act for it to become part of the Delaware Constitution.

AN ACT TO AMEND THE LAWS OF DELAWARE RELATING TO PUBLIC EDUCATION FUNDING.

This Act recognizes that the Public Education Funding Committee’s (PEFC) recommended hybrid model formula to determine public education funding is good public policy and that implementation of the hybrid model should not be delayed any longer than absolutely necessary. As such, this Act provides authority for the Department of Education (Department) to begin making the changes to systems that are necessary to implement the hybrid model for Fiscal Year 2028. This Act also encourages that, in collaboration with the PEFC, the Department incorporate elements of the hybrid model in the development of the Governor’s Recommended Budget for Fiscal Year 2028 for consideration by the 154th General Assembly. However, during this transition, a school district or charter school should not receive a state appropriation for Fiscal Year 2028 that is lower than the amount that school received in Fiscal Year 2027. The PEFC was established under Senate Concurrent Resolution No. 201 (152nd General Assembly) on June 27, 2024, and then re-established under House Concurrent Resolution No. 2 (153rd General Assembly) on January 21, 2025, to conduct a comprehensive review of public education funding for all students and populations served by school districts and charter schools (public schools) and develop a roadmap of recommendations to implement improvements to the public education funding system. The PEFC’s recommends adopting a new public education funding framework, known as the “hybrid model”, that combines the current, resource-based funding formula with a student-based, weighted funding model. The hybrid model will improve equity in public school funding and facilitate gains in student achievement by increasing flexibility in how public schools may use appropriated money. The PEFC recommendations include accountability measures as an important balance to the increased flexibility and that the equalization formula must be modernized.

AN ACT TO AMEND TITLE 14 OF THE DELAWARE CODE RELATING TO THE PUBLIC EDUCATION FUNDING COMMISSION.

Under Senate Concurrent Resolution No. 201 (152nd General Assembly) and House Concurrent Resolution No. 2 (153rd General Assembly), the Public Education Funding Commission (Commission) has studied how to improve Delaware's public education funding policies so that public school funding is equitable and appropriated in a manner that allows public schools, including both school districts and charter schools, to not only spend all money that is appropriated but to do so in a manner that best meets the needs of the students in each school. This Act implements the Commission’s recommendation that the Public Education Funding Commission be established as a permanent body. As set forth in Senate Bill No. 302 (153rd General Assembly), the Commission recommended that the General Assembly enact what is known as the hybrid formula. The hybrid formula combines elements of the current funding calculations with a weighted needs-based approach that provides additional funding for students who receive career and technical education or special education services, who are multilingual learners, and who live in low-income households. Codified, the Commission will have a crucial role in implementing and maintaining the benefits of the hybrid model by continually reviewing the hybrid model, including the amounts of the required weights, if school spending of state appropriations complies with the applicable requirements, and making recommendations for improvements. The continual review of public education funding by the Commission will allow adjustments to be made on a gradual and incremental basis as needed.

AN ACT TO AMEND TITLE 16 OF THE DELAWARE CODE RELATING TO PFAS IN FIREFIGHTING FOAM AND EQUIPMENT.

This Act prohibits the sale of class B firefighting foam that contains intentionally added PFAS chemicals starting January 1, 2028. An exception is provided for a bulk petroleum facility, provided that the bulk petroleum facility applies to DNREC for a 5-year exemption. The exemption period may be extended for additional 2-year periods, up to a total of 13 years. If an exempt bulk petroleum facility uses foam containing PFAS chemicals, they must notify DNREC. Under this Act, a manufacturer must notify its customers in the State regarding the prohibition of firefighting foam containing PFAS chemicals by January 1, 2027. By March 1, 2028, the manufacturer must recall or reimburse purchasers, unless the purchaser is exempt as a bulk petroleum facility. The recall must include the safe transport and storage of PFAS-containing firefighting foam until the Department identifies a safe disposal technology. A manufacturer in violation of this Act is subject to a $5,000 civil penalty for a first offense and a $10,000 for a second, or subsequent offense. Finally, this Act requires that firefighting personal protective equipment (PPE) that contains PFAS chemicals be sold with a written notice that states that the PPE contains PFAS chemicals. The manufacturer or seller of the PPE must retain the written notice on file for at least 3 years from the date of transaction. Failure to provide written notice of PFAS chemicals in PPE will subject the manufacturer or seller to a civil penalty of $100 per occurrence. House Substitute 1 to HB 356 differs from HB 356 in the following ways: (1) It replaces the term “terminal” with the broader term “bulk petroleum facility” which clarifies those facilities that may apply for an exemption under this Act. (2) Clarifies the definition of PFAS or polyfluoroalkyl substances. (3) Extends the exemption period for bulk petroleum facilities from 1 to 5 years. (4) Provides additional 2-year extensions to the 5-year exemption period, so long as the total exemption period does not exceed 13 years. (5) Permits a bulk petroleum facility to use PFAS-containing firefighting foam to aid another facility. (6) Removes the requirement that DNREC assist state agencies and local governments in identifying and obtaining class B firefighting foam that does not contain PFAS chemicals.
