CITIZEN PARTICIPATION IN THE REGULATORY PROCESS Delaware citizens and other interested parties may participate in the process by which administrative regulations are adopted, amended or repealed, and may initiate the process by which the validity and applicability of regulations is determined. Under 29 Del.C. §10115 whenever an agency proposes to formulate, adopt, amend or repeal a regulation, it shall file notice and full text of such proposals, together with copies of the existing regulation being adopted, amended or repealed, with the Registrar for publication in the Register of Regulations pursuant to §1134 of this title. The notice shall describe the nature of the proceedings including a brief synopsis of the subject, substance, issues, possible terms of the agency action, a reference to the legal authority of the agency to act, and reference to any other regulations that may be impacted or affected by the proposal, and shall state the manner in which persons may present their views; if in writing, of the place to which and the final date by which such views may be submitted; or if at a public hearing, the date, time and place of the hearing. If a public hearing is to be held, such public hearing shall not be scheduled less than 20 days following publication of notice of the proposal in the Register of Regulations. If a public hearing will be held on the proposal, notice of the time, date, place and a summary of the nature of the proposal shall also be published in at least 2 Delaware newspapers of general circulation. The notice shall also be mailed to all persons who have made timely written requests of the agency for advance notice of its regulation-making proceedings. The opportunity for public comment shall be held open for a minimum of 30 days after the proposal is published in the Register of Regulations. At the conclusion of all hearings and after receipt, within the time allowed, of all written materials, upon all the testimonial and written evidence and information submitted, together with summaries of the evidence and information by subordinates, the agency shall determine whether a regulation should be adopted, amended or repealed and shall issue its conclusion in an order which shall include: (1) A brief summary of the evidence and information submitted; (2) A brief summary of its findings of fact with respect to the evidence and information, except where a rule of procedure is being adopted or amended; (3) A decision to adopt, amend or repeal a regulation or to take no action and the decision shall be supported by its findings on the evidence and information received; (4) The exact text and citation of such regulation adopted, amended or repealed; (5) The effective date of the order; (6) Any other findings or conclusions required by the law under which the agency has authority to act; and (7) The signature of at least a quorum of the agency members. The effective date of an order which adopts, amends or repeals a regulation shall be not less than 10 days from the date the order adopting, amending or repealing a regulation has been published in its final form in the Register of Regulations, unless such adoption, amendment or repeal qualifies as an emergency under §10119. Any person aggrieved by and claiming the unlawfulness of any regulation may bring an action in the Court for declaratory relief. No action of an agency with respect to the making or consideration of a proposed adoption, amendment or repeal of a regulation shall be subject to review until final agency action on the proposal has been taken. When any regulation is the subject of an enforcement action in the Court, the lawfulness of such regulation may be reviewed by the Court as a defense in the action. Except as provided in the preceding section, no judicial review of a regulation is available unless a complaint therefor is filed in the Court within 30 days of the day the agency order with respect to the regulation was published in the Register of Regulations.

Ch.60) Secretary’s Order No. 2005-A-0017 Date of Issuance: March 8, 2005 Effective Date: March 8, 2005 Under the authority vested in the Secretary of the Department of Natural Resources and Environmental Control under 29 Del. C. §§8001 et seq., the following findings and conclusions are entered as an Order of the Secretary: 1.Based on the record developed, as reviewed in the Hearing Officer’s Report (“Report”), dated March 7, 2005, and appended hereto and incorporated herein, I find and conclude that the record supports approval in final form of the proposed “Amendments to Delaware Phase II Attainment Demonstration: Mid-Course Review on Progress Toward Attainment of the 1 hour Ozone National Ambient Air Quality Standard” (hereinafter “MCR”). The proposed MCR was prepared by the Department’s Air Quality Management (“AQM”) Section within the Division of Air and Waste Management. 2.The record supports the Department’s approval of the proposed MCR as the final MCR. The MCR demonstrates that Delaware’s measures to control VOC and NOx emissions have been adequate to meet the federal one- hour ozone standard. In addition, when supplemented by additional control measures to go into effect in 2005 and by those to be developed and implemented in the future years, Delaware should be able to meet the more stringent 8-hour standard by 2010, particularly if the federal government or other states also take steps to reduce the ozone and precursors that are produced in other states and then transported by the wind into Delaware. 3.The MCR approved by this Order shows that New Castle and Kent Counties will reduce VOC and/or NOx emissions by the required 42% target amount based upon the existing control measures and those to be implemented in 2005. 4.In order to meet the current 2010 standards, the MCR shows that Delaware will need 1) additional state control measures to be implemented before 2010, and 2) federal regulation to control ozone and ozone precursor transported into Delaware. 5.The draft MCR, as published in the November 2004 Delaware Register of Regulations, should be adopted as the Department’s final action, and be published as a Notice in the Delaware Register of Regulations in the next available issue. 6.The Department provided adequate notice of the public hearing in a manner required by the applicable law and regulations. 7.The Department has an adequate record for its decision, and no further public hearing is appropriate or necessary.

Under the requirements of sections 182(b)(1) and 182(d) of the Clean Air Act Amendments of 1990 (CAAA) regarding the 1-hour ozone NAAQS, Delaware has implemented and committed to implement a comprehensive list of control measures to reduce emissions of volatile organic compounds (VOC) and oxides of nitrogen (NOx) in its two severe nonattainment counties, i.e., Kent and New Castle Counties. Those measures include federal and state rules and controls that cover a large variety of emission sources, including point, area, on-road mobile and off-road mobile sources. This document show that (1) Delaware’s control measures have produced significant and consistent VOC and NOx emission reductions since 1990, (2) as a result of those emission reductions, the ambient air quality regarding ozone has been significantly improved toward attainment of the 1-hour ozone standard in 2005, and (3) therefore, Delaware’s current control framework is adequate and no additional controls will be needed before EPA revokes the 1-hour ozone standard in June of 2005. However, it must be noted that ozone and ozone precursor transport continues to negatively impact Delaware’s air quality, and that EPA should cause such transport to be mitigated prior to Delaware’s 8-hour ozone attainment date of 2010. 1.0Introduction 1.1Background Under the Clean Air Act Amendments of 1990 (CAAA), Kent and New Castle Counties in Delaware are classified as severe nonattainment areas with respect to the 1-hour National Ambient Air Quality Standard (NAAQS) for ground-level ozone (Reference 1). The CAAA requires Delaware to submit to the U.S. Environmental Protection Agency (EPA) a State Implementation Plan (SIP) revision to demonstrate that the 1-hour ozone standard will be attained by 2005 in these two counties with necessary and adequate control measures to reduce emissions of volatile organic compounds (VOC) and oxides of nitrogen (NOx). That SIP revision, entitled “Delaware Phase II Attainment Demonstration for Philadelphia-Wilmington-Trenton Ozone Nonattainment Area,” was originally submitted to EPA in May 1998, and amended in October 1998, January 2000, December 2000, October 2001, and June 2003 (Reference 2). In order to settle a complaint filed by six environmental groups in U.S. District Court, EPA required, as a condition of approval of the Phase II Attainment Demonstration SIP of each state in the Philadelphia- Wilmington-Trenton non-attainment area, that a mid-course review (MCR) be conducted to evaluate the progress being made toward attainment of the 1-hour ozone standard (Reference 3). The results of the MCR were required to be submitted to EPA by December 31, 2003, and would be used to determine if any additional controls would be necessary to ensure the attainment by 2005. Pursuant to this EPA requirement, Delaware committed in its January 2000 SIP revision to perform an MCR by December 31, 2003. This MCR requirement was also imposed on other states with severe non-attainment areas with respect to the 1-hour ozone standard. Following the above, an order of the U.S. Court of Appeals for D.C. Circuit delayed the implementation of EPA’s NOx Transport SIP Call from 2003 to 2004. The NOx Transport SIP Call is a significant part of the overall 1-hour ozone attainment strategy. In response to this court order, EPA allowed states to revise the MCR due date to a date after May 31, 2004. The later MCR date is believed to better serve the MCR purpose (i.e., to enable states to evaluate the adequacy of their attainment strategy, and to facilitate initiation of additional control measures if necessary). Many states affected by the NOx SIP Call emission reductions, including those in the Ozone Transport Region (OTR), have revised their commitment to conduct and submit the MCR on a schedule later than May 31, 2004 (Reference 4). In its June 2003 amendments to the Phase II Attainment demonstration SIP revision, Delaware also changed its original MCR completion date from December 31, 2003 to December 31, 2004. This document fulfills Delaware’s commitments in its January 2002 and June 2003 amendments to the Phase II Attainment Demonstration SIP revision to conduct a MCR by December 31, 2004. 1.2 Responsibilities The agency with direct responsibility for preparing and submitting this document is Delaware Department of Natural Resources and Environmental Control (DNREC), Division of Air and Waste Management (DAWM), Air Quality Management Section (AQM), under the direction of Ali Mirzakhalili, Program Administrator. The working responsibility for Delaware’s air quality management planning falls within the Planning and Community Protection (PCP) Branch of AQM Section, under the management of Raymond H. Malenfant, Program Manager and Ronald A. Amirikian, Planning Supervisor. Frank F. Gao, Environmental Engineer in the Airshed Evaluation and Planning Program in the PCP Branch, is the project leader and principal author of this document. Questions or comments regarding this document should be addressed to F. Gao, (302)323-4542, AQM, 715 Grantham Lane, New Castle, DE 19720, or be e-mailed to Frank.Gao@state.de.us. 2.0Emission Reduction Requirements and Control Strategies 2.1 Rate-of-Progress Requirements In order for the severe nonattainment areas (NAA) to attain the 1-hour ozone standard by 2005, Sections 182(b)(1) and 182(d) set forth the following specific rate-or- progress emission reduction requirements: (1) to achieve by 1996 an actual VOC emission reduction of at least 15% of its 1990 VOC emission level, and (2) to achieve an additional 3% per year VOC and/or NOx emission reductions from the 1990 emission levels between 1997 and 2005. Delaware developed its 1990 Base Year Emission Inventory in May 1994, and approved by EPA in March 1996 (Reference 5). This 1990 base year emission inventory is used as the basis for Delaware to develop its rate-of- progress plans and control strategies toward attainment of the 1-hour ozone standard in 2005. A summary of VOC and NOx emissions from all anthropogenic sources in Kent and New Castle Counties in the 1990 Base Year Inventory is presented in Table 1. Table 1. Summary of VOC and NOx Emissions (in TPD) in 1990 Base Year Inventory* *Data obtained from Delaware 1990 Base Year Emission Inventory (Reference 5). To meet the rate-of-progress emission reduction requirements, Delaware has developed the following four rate-of-progress plans (RPP) for its two severe nonattainment counties (i.e., Kent and New Castle Counties): the 1996 RPP, the 1999 RPP, the 2002 RPP and the 2005 RPP. The 1996 RPP specifies Delaware’s control strategies to achieve the required 15% VOC emission reduction. The 1999 RPP, the 2002 RPP and the 2005 RPP describe Delaware’s emission control strategies to achieve an additional 9% VOC and/or NOx reductions in the 3-year periods of 1997-1999, 2000-2002, and 2003-2005, respectively. By meeting the rate-of-progress emission reduction requirements, these RPPs set forth VOC and/or NOx emission targets for 1996, 1999, 2002, and 2005, which are defined as rate-of-progress milestone years. A summary of VOC and /or NOx emission targets for individual milestone years are presented in Table 2. Details of how to estimate emission reductions and emission targets can be found in References 6, 7, 8, 9, 10, and 11. Table 2. Delaware VOC and/or NOx Emission Targets for Individual Milestone Years. *NOx reduction was not required for the 1996 milestone year. As mentioned above, from 1990 base year to 2005 attainment year, Delaware is required to achieve a total of 42% emission reduction from the 1990 base year level, in which 15% reduction must be obtained from VOC emissions between 1990 and 1996. To achieve this 42% emission reduction goal by 2005, Delaware has implemented and/or proposed numerous control measures. These control measures include federal mandatory rules and Delaware state regulations being promulgated prior to the peak ozone season of 2005. These rules and regulations cover a large variety of VOC and NOx emission sources in all anthropogenic source sectors in Kent and New Castle Counties. A list of the control measures, along with their implementation dates, is given in Table 3. Detailed descriptions of individual rules and regulations can be found in Delaware 2005 RPP (Reference 10), and Delaware Regulations Governing Control of Air Pollution (Reference 12). Table 3. Control Measures for VOC and NOx Emissions in 2005 RPP. 2.2 Attainment Demonstration Requirements on Emission Reductions As mentioned earlier, Delaware submitted to EPA its original Phase II Attainment Demonstration SIP revision for the Delaware part of the Philadelphia-Wilmington- Trenton Ozone Nonattainment Area in 1998, and amended it several times thereafter. In this Phase II Attainment Demonstration SIP revision, Delaware uses results from comprehensive photochemical models, which incorporate all emission control measures in Table 3, to demonstrate Delaware’s capability of attaining the 1-hour ozone standard in 2005. In December 1999, however, EPA decided that VOC and NOx emission reductions from all control measures being contained in all involved states’ 2005 RPPs would not be enough to guarantee the entire Philadelphia- Wilmington-Trenton Ozone Nonattainment Area to attain the 1-hour ozone standard in 2005, and therefore the states in this entire nonattainment area must implement additional emission controls to offset the emission reduction shortfalls (Reference 13). To meet EPA’s requirements regarding the emission reduction shortfalls, Delaware, along with other states in the Ozone Transport Region (OTR), developed some new or more stringent controls or rules to achieve additional VOC and NOx emission reductions. Delaware submitted to EPA in October 2001 its amendments to the Phase II Attainment Demonstration SIP revision, which specified those promulgated rules to achieve these additional emission reductions (Reference 13). A summary of these rules is presented in Table 4. Table 4. Additional Controls and Rules to Address Emission Reduction Shortfalls. 3.0Demonstration of Adequate Progress toward Attainment 3.1 Emission Trends from 1990 to 2002 Under Section 182(a) of the CAAA, Delaware is required to compile comprehensive periodic emission inventories of ozone precursors for 1993, 1996, 1999, 2002 and 2005. These periodic emission inventories cover all sources included in Delaware’s 1990 Base Year Emission Inventory and serve to monitor the overall effectiveness of control measures specified in individual rate-of-progress plans as described in the previous section. Delaware submitted to EPA its 1993 periodic emission inventory (PEI) in January 1998, its 1996 EPI in November 1999, its 1999 PEI in June 2002, and its 2002 PEI in June 2004. For the purpose of demonstrating emission trends, a summary of VOC and NOx emissions (in the unit of TPD) in the 1993 PEI, 1996 PEI, 1999 PEI and 2002 PEI is presented in Table 5. Table 5. Summary of Delaware 1993, 1996, 1999 and 2002 Emission Inventories. Comparison of the emission targets in Table 2 and the PEI emissions in Table 5 indicates that (1) VOC emissions in Delaware’s two nonattainment counties are well below the targets since 1996, and in 2002 the PEI VOC emission is 23.42 TPD below the target, (2) NOx emission is below the 1999 target (the first year when the NOx target is required), but exceeds the 2002 target by 1.37 TPD. It should be pointed out that this over-target NOx emission of 1.37 TPD is equivalent to a VOC emission of 1.15 TPD, as explained in Delaware’s 2002 Milestone Compliance Demonstration document (Reference 14). In other words, the overall or net emission in 2002, if expressed as a VOC equivalent emission, is still 22.27 TPD (i.e., 23.42 – 1.15 = 22.27) below the required target. Therefore, it can be concluded that, with all controls and rules in Delaware’s RPPs being implemented, the overall VOC and NOx emission trend from 1990 to 2002 in Delaware’s NAA is dramatically decreasing and well below the milestone year emission targets required by CAAA. At the present time (i.e., when this MCR document is being developed), a comparison of the 2005 actual emissions with the 2005 RPP emission targets is not possible because the 2005 emission inventory is not available. However, Delaware believes that with additional controls and rules being implemented in the 2003-2005 period, such as the Federal NOx Transport SIP Call and those specified in Delaware’s Phase II Shortfalls SIP, the decreasing VOC/ NOx emission trends in Delaware will continue and be well below the 2005 emission targets under the 1-hour ozone standard. 3.2 Monitored Ambient Ozone Data under the 1-Hour Standard As pointed out in the previous subsection, the overall VOC and NOx emissions in Delaware’s NAA has been continuously decreasing since 1990 due to timely implementation of effective control measures over a large variety of emission sources. As a result, the ambient air quality in Delaware regarding ozone has been continuously improved since 1996, the first rate-of-progress milestone year. The improvement in ozone ambient air quality in Delaware’s NAA can be demonstrated by changes in the number of exceedances of the 1-hour ozone standard. A summary of the monitored exceedances since 1997 is presented in Table 6 (the 1996 data were missed). Table 6 indicates that, by the attainment definition of the CAAA, Kent County has been in attainment of the 1-hour ozone standard since 2002. For New Castle County, there has been only one extra exceedance that keeps it in the nonattainment status since 2002. Table 6. Delaware NAA’s 1-Hour Ozone Standard Exceedances after 1996. * The 1996 data were missed. The improvement in ozone air quality can be also seen from the design value data. A summary of the 1-hour ozone design values for the two nonattainment counties after 1996 is present in Table 7. The design values are based on the ambient ozone concentrations monitored in the 1996-2004 period. These monitored data indicate that the 1-hour ozone design value in Kent County has been below the 1-hour ozone standard in the past three 3-year periods. The 1-hour ozone design value in New Castle County has been slightly above the 1-hour ozone standard, but below the truncation margin (i.e., 0.124 ppm), in the past two 3-year periods. According to CAAA’s attainment/nonattainment designation standards and procedures, both Kent and New Castle Counties could be currently given an attainment status. Table 7. Delaware NAA’s 1-Hour Ozone Design Values (ppm). * The 1996 data were missed. In summary, the ambient ozone data in Table 6 and 7 have shown that Delaware’s NAA has maintained a consistent and adequate progress toward attainment of the 1- hour ozone standard in 2005. With some upcoming controls and rules, especially the Federal NOx SIP Call, it can be reasonably assumed that this adequate progress will continue into 2005 toward the attainment goal of the 1-hour ozone standard. However, it should noted that while Delaware is on track to attain compliance with the 1-hour ozone standard, and that Delaware is now moving forward with additional reductions to meet the 8-hour ozone standard, significant negative impact from upwind states will prevent Delaware from attainment of the 8-hour ozone standard by 2010. The EPA must mitigate this impact prior to Delaware’s 2010 8- hour ozone attainment date. 3.3 Monitored Ambient Ozone Data under the 8-Hour Standard In April 2004, all three Delaware counties were designated as moderate nonattainment areas under the 8- hour ozone standard (Reference 15). In its final rule for implementing the 8-hour ozone standard, EPA indicates that states can use the mid-course-reviews to ensure that progress is being made consistent with needs for the 8-hour NAAQS (Reference 16). To this end, a summary of the 8-hour ozone design values for Delaware’s three counties is presented in Table 8. Table 8. Delaware NAA’s 8-Hour Ozone Design Values (ppm). From Table 8, it can bee seen that the 8-hour ozone design values in all three counties exhibit a clear decreasing trend toward attaining the 8-hour standard. This trend is in fact in parallel to the 1-hour ozone design value trend exhibited in Table 7. This fact indicates that the control measures being implemented under the 1-hour ozone standard, and being reviewed in this document (Table 3 and Table 4), have already initiated a progress that is consistent with the needs toward attaining the 8-hour ozone standard. 3.4 Summary and Concluding Remarks 3.4.1Since 1996, Delaware has implemented numerous control measures over a large variety of VOC and NOx emission sources to meet the CAAA requirements for attaining the 1-hour ozone standard. Those control measures have led to consistent and significant VOC and NOx emission reductions. 3.4.2Since 1996, as a result of the above emission reductions, Delaware’s ambient air quality regarding the 1-hour ozone standard has been continuously improved, and the progress toward attaining the 1-hour ozone standard appears to be adequate. 3.4.3The control measures under the 1-hour ozone standard have ensured a beginning of adequate progress toward attaining of the 8-hour ozone standard. However, to maintain this progress and ensure attainment of the 8-hour ozone standard, additional control measures are needed in Delaware, and the EPA must cause both the ozone and ozone precursor transport into Delaware, to be mitigated from upwind states before the attainment year of 2010. 3.4.4The analyses in this document shows that Delaware’s control framework, including control measures being implemented and those promulgated but not yet in effect, is adequate under the CAAA requirements toward attaining the 1-hour ozone standard, and provide an adequate basis for the transition to planning for attainment of the 8- hour ozone standard. 4.0References 1.Federal Clean Air Act, 42 U.S.C.A.
