and 7 DE Admin. Code 1114 (Visible Emissions)
(pursuant to E.O. 36 DNREC Regulatory Review)
Date of Issuance: October 14, 2013
Effective Date of the Amendment: November 11, 2013
1101 Definitions and Administrative Principles
Under the authority vested in the Secretary of the Department of Natural Resources and Environmental Control ("Department" or "DNREC") the following findings, reasons and conclusions are entered as an Order of the Secretary in the above-referenced rulemaking proceeding.
Background and Procedural History
This Order considers proposed regulations to amend 7 DE Admin. Code 1101 (Definitions and Administrative Principles); 7 DE Admin. Code 1104 (Particulate Emissions from Fuel Burning Equipment); and 7 DE Admin. Code 1114 (Visible Emissions), as a result of the Department's exhaustive review of its existing regulations, pursuant to Governor Markell's Executive Order No. 36 (hereinafter referred to as "E.O. 36"). In June of 2012, Governor Markell issued E.O. 36, which directed all state agencies, including DNREC, to perform a focused review of their existing, older regulations, identify and remove regulatory hurdles, and modernize and streamline any regulations that may be outdated or unnecessarily burdensome, while maintaining the state's commitment to improving public health and environmental performance.
Among the considerations of the Department's aforementioned focused review of its existing regulations under E.O. 36 was to ensure that the same continued to serve the original purpose for which they were adopted, and to provide for improvements. To that end, three sections of Delaware's existing air regulations were identified as needing revision at this time:
(1) 7 DE Admin. Code 1101, Definitions and Administrative Principles:
In 2008, Delaware's air regulations were recoded and established in 7 DE Admin. Code 1100. The regulatory language in 1101 was inadvertently not updated, and continues to reference the prior "Regulations Governing the Control of Air Pollution". The outdated references could lead citizens and industry searching for documents that no longer exist, or potentially to an incorrect regulatory interpretation. Thus, revisions to this existing air regulation are being proposed to correct the outdated references.
(2) 7 DE Admin. Code 1104, Particulate Emissions from Fuel Burning Equipment:
Revisions are being proposed by the Department to this existing air regulation to clarify that the exemptions found in Sections 1.2 and 1.4 of this regulation are for the capacity of the unit, and not the operating rate. The revised regulation will, once promulgated, be submitted to the U.S. Environmental Protection Agency ("EPA") as a revision to Delaware's State Implementation Plan ("SIP").
(3) 7 DE Admin. Code 1114, Visible Emissions:
Revisions are being proposed by the Department to this existing air regulation to delete the alternate opacity standard in Section 2.3. This alternate standard was established for a petroleum refinery unit prior to the installation of modern pollution control equipment in 2006. The installation of the pre-scrubber on the catalytic cracking unit in 2006 makes this alternate opacity standard obsolete, and the unit is now subject to compliance with the general 20 percent opacity limit in Section 2.1. This is a burdensome requirement to administer and track, and is no longer either relevant or necessary. The revised regulation will, once promulgated, be submitted to the EPA as a revision to Delaware's State Implementation Plan ("SIP").
The Department's Division of Air Quality commenced the regulatory development process with Start Action Notices 2013-13(E.O.36), 2013-15(E.O.36), and 2013-16(E.O.36), respectively. The Department published its initial proposed regulation Amendments in the July 1, 2013 Delaware Register of Regulations, and held a public hearing on August 1, 2013.
The proposed Amendments were thoroughly vetted by the Department at the aforementioned public hearing on August 1, 2013. Pursuant to Delaware law, the record remained open for fifteen (15) additional days subsequent to the date of the public hearing, for the purpose of receiving additional public comment. No public comment was received by the Department from the public at any time during the course of this proposed promulgation. It should also be noted that all proper notification and noticing requirements concerning this proposed promulgation were met by the Department. Proper notice of the hearing was provided as required by law.
The Department's presiding hearing officer, Lisa A. Vest, prepared a Hearing Officer's Report dated September 28, 2013 (Report). The Report recommends certain findings and the adoption of the proposed Amendments as attached to the Report as Appendix A.
Findings and Discussion
I find that the proposed Amendments are well-supported by the record developed by the Department, and I adopt the Report to the extent it is consistent with this Order. The Department's experts developed the record and drafted the proposed Amendments. As previously noted, no public comment was received by the Department from the public at any time during the course of this proposed promulgation.
I find that the Department's experts in the Division of Air Quality fully developed the record to support adoption of these Amendments. The adoption of this Order will enable Delaware to update its existing, older air regulations by bringing the regulatory standards up-to-date with current federal requirements and provide additional clarity to both the regulated community and the public at large with respect to these issues. Moreover, the revisions to 7 DE Admin. Code 1104 and 7 DE Admin. Code 1114 will also be submitted to the EPA as a revision to update Delaware's State Implementation Plan.
In conclusion, the following findings and conclusions are entered:
1.) The Department has jurisdiction under its statutory authority to issue an Order adopting these proposed Amendments as final;
2.) The Department provided adequate public notice of the proposed Amendments, and provided the public with an adequate opportunity to comment on the initial proposed Amendments, including at the public hearing held on August 1, 2013;
3.) The Department held a public hearing on August 1, 2013 in order to consider public comment before making any final decision;
4.) The Department's Hearing Officer's Report, including its recommended record and the recommended Amendments as set forth in Appendix A, are adopted to provide additional reasons and findings for this Order;
5.) The adoption of this Order will enable Delaware to update its existing, older regulations by bringing the regulatory standards up-to-date with current federal requirements and provide additional clarity to both the regulated community and the public at large with respect to these issues. Moreover, the revisions to 7 DE Admin. Code 1104 and 7 DE Admin. Code 1114 will also be submitted to the EPA as a revision to update Delaware's State Implementation Plan;
6.) The recommended Amendments should be adopted as final regulation Amendments because Delaware will be able to (1) update its existing, older air regulations (as well as its SIP), and provide additional clarity and understanding to Delaware citizens with regard to these matters; (2) further the purpose of Governor Markell's initiatives as set forth in Executive Order No. 36, to wit: strengthen Delaware's economy by modernizing and streamlining regulations that may be outdated or unnecessarily burdensome, while maintaining the state's commitment to improving public health and environmental performance; and, lastly, because (3) the amendments are well supported by documents in the record;
7.) The Department shall submit this Order approving the final regulation 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.
