Under the authority vested in the Secretary of the Department of Natural Resources and Environmental Control ("Department" or "DNREC") pursuant to 7 Del.C. §§6006, 6010, the following findings of fact based on the record, reasons and conclusions are entered as an Order of the Secretary in the above-referenced regulatory proceeding.
This Order relates to proposed regulation Amendments to 7 DE Admin. Code 1375: Delaware Regulations Governing Hazardous Substance Cleanup. The Department's Division of Waste and Hazardous Substances, Site Investigation and Restoration Section, commenced the regulatory development process with Start Action Notice 2013-29 dated November 8, 2013. The Department published its initial proposed regulation Amendments in the April 1, 2015 Delaware Register of Regulations. The Department then held a public hearing on April 29, 2015. Consistent with 29 Del.C. §10118(a), the public hearing record remained open for public comment through May 14, 2015.
Based on the record developed by the Department's experts and established by the Hearing Officer's Report, I find that the proposed regulatory Amendments to 7 DE Admin. Code 1375: Delaware Regulations Governing Hazardous Substance Cleanup are well-supported. Therefore, the recommendations of the Hearing Officer are hereby adopted, and I direct that the proposed regulatory Amendments be promulgated as final.
1. The Department has the statutory basis and legal authority to act with regard to the proposed Amendments to 7 DE Admin. Code 1375: Delaware Regulations Governing Hazardous Substance Cleanup, pursuant to 7 Delaware Code, Chapter 91;
2. The Department has jurisdiction under its statutory authority, pursuant to 7 Del.C. Ch. 60, to issue an Order adopting these proposed regulatory amendments as final;
6. The Department has reviewed these proposed regulatory Amendments in the light of the Regulatory Flexibility Act, consistent with 29 Del.C. Ch. 104, and believes the same to be lawful, feasible and desirable, and that the recommendations as proposed should be applicable to all Delaware citizens equally;
7. The Department's proposed regulatory Amendments, as published in the April 1, 2015 Delaware Register of Regulations, and as set forth in Appendix "A" as noted above, are adequately supported, are not arbitrary or capricious, and are consistent with the applicable laws and regulations. Consequently, they are approved as final regulatory amendments, which shall go into effect ten days after their publication in the next available issue of the Delaware Register of Regulations; and
8. The Department shall submit this Order approving as final the proposed Amendments to 7 DE Admin. Code 1375: Delaware Regulations Governing Hazardous Substance Cleanup 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.
