Statutory Authority: 7 Delaware Code, Chapter 60; (7 Del.C., Ch. 60)
7 DE Admin. Code 1120
FINAL
Secretary’s Order No.: 2012-A-0040
Date of Issuance: November 9, 2012
Effective Date of the Amendment: December 11, 2012
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 the proposed regulatory amendments to 7 DE Admin. Code 1120, New Source Performance Standards, to repeal of Section 29, “Standards of Performance for Hospital/Medical/Infectious Waste Incinerators”.
On September 15, 1997, the EPA adopted a New Source Performance Standard and Emission Guideline at 40 CFR Part 60, Subparts Ec and Ce, which were applicable to both new and existing hospital, medical, and infectious waste incinerator (HMIWI) units, respectively. At the same time, the EPA published a related emissions guideline to assist the States in developing their “Section 129 Plan” for existing sources under 40 CFR Part 60 Ce. EPA’s September 15, 1997 promulgation called for Delaware to submit its “Section 129 Plan” within one year.
Over the next twelve months, the Department determined that there were three HMIWI units in Delaware: The DuPont Experimental Station in Wilmington; Kent General Hospital in Dover; and Nanticoke Memorial Hospital in Seaford. DNREC then drafted its proposed Section 29 of Regulation 1120, as well as its “Section 129 Plan”, and conducted both a public workshop and public hearing regarding this matter. As required under the Clean Air Act, Delaware subsequently adopted Section 29, “Standards of Performance for Hospital/Medical/Infectious Waste Incinerators” into Regulation 1120 on September 1, 1998. Accordingly, the Department submitted its “Section 129 Plan” to the EPA, and EPA approved Delaware’s plan on April 14, 2000.
In 2007, the EPA completed its review for its aforementioned hospital, medical and infectious waste incinerator regulation, and determined that revisions to the same were warranted. In October of 2009, the EPA revised the New Source Performance Standard applicable to newly-built sources and published a revised emissions guideline for existing sources to assist the States in revising their “Section 129 Plan”. Once again, EPA’s revision to its emissions guideline called for Delaware to submit its revised “Section 129 Plan” within one year.
Upon the Department’s review of its “Section 129 Plan”, DNREC found that the three existing sources referenced above had since shut down and dismantled their incinerators, and that no newly-built hospital, medical or infectious waste incinerators had been installed. Thus, it was unnecessary to revise Delaware’s “Section 129 Plan”. On June 17, 2010, the Department submitted a request to EPA Region 3 to have Delaware’s “Section 129 Plan” withdrawn, and on November 30, 2010, the EPA formally withdrew Delaware’s plan.
Delaware is now proposing to repeal Section 29 of Regulation 1120, as its inherent regulatory requirements are currently outdated, and its continuance is no longer justified, due to the fact that there is no hospital, medical or infectious waste incinerator in Delaware that are subject to it. Should a facility wish to construct a new HMIWI unit in the future, such installation would be regulated under the amended 40 CFR Part 60, Subpart Ec, which EPA formally adopted on October 6, 2009.
The Department’s Division of Air Quality commenced the regulatory development process with Start Action Notice 2012-10. The Department published the proposed regulatory amendment in the August 1, 2012 Delaware Register of Regulation and held a public hearing on August 22, 2012. The Department’s presiding hearing officer, Lisa A. Vest, prepared a Hearing Officer’s Report dated October 9, 2012 (Report). The Report recommends certain findings and the adoption of the proposed Amendment as attached to the Report as Appendix A.
Findings and Discussion
I find that the proposed Amendment is well-supported by the record developed by the Department, and adopt the Report to the extent it is consistent with this Order. The Department’s experts developed the record and drafted the proposed Amendment. As noted in the aforementioned Hearing Officer’s Report, no members of the public attended the aforementioned hearing on August 22, 2012, nor were any comments received from the public by the Department, either at the time of the hearing or prior to the record formally closing in this matter on September 6, 2012.
I find that the Department’s experts in the Division of Air Quality fully developed the record to support adoption of these Amendments. Promulgation of the aforementioned proposed amendment to 7 DE Admin. Code 1120 will repeal Section 29, as its inherent regulatory requirements are currently outdated, and its continuance is no longer justified, due to the fact that there is no hospital, medical or infectious waste incinerator in Delaware subject to it. Should a facility wish to construct a new HMIWI unit in the future, such installation would be regulated under the amended 40 CFR Part 60, Subpart Ec, which EPA formally adopted on October 6, 2009.
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 Amendment, and provided the public with an adequate opportunity to comment on the proposed Amendment, including at a public hearing;
3.) The Department held a public hearing on the proposed Amendment on August 22, 2012;
4.) The Department’s Hearing Officer’s Report, including its recommended record and the recommended Amendment as set forth in Appendix A, are adopted to provide additional reasons and findings for this Order;
5.) The recommended Amendment does not reflect any change from the proposed regulation Amendment as published in the August 1, 2012, Delaware Register of Regulations;
6.) Promulgation of the aforementioned proposed amendment to 7 DE Admin. Code 1120 will repeal Section 29, as its inherent regulatory requirements are currently outdated, and its continuance is no longer justified, due to the fact that there is no hospital, medical or infectious waste incinerator in Delaware subject to it. Should a facility wish to construct a new HMIWI unit in the future, such installation would be regulated under the amended 40 CFR Part 60, Subpart Ec, which EPA formally adopted on October 6, 2009; and
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.

Additional procedures for location of continuous monitoring systems contained in the applicable Performance Specifications of this regulation shall be used.
1.3.10 Owners or operators of all continuous monitoring systems for measuring opacity shall reduce all data to 15-second averages. Consecutive 15-second averages, each less than the applicable standard may be recorded cumulatively. The 15-second averages in excess of the applicable standard shall be recorded for the time of occurrence. Any such averages in excess of the applicable standard shall be reported to the Department as excess emissions.
1.3.11 For systems other than opacity, one-hour averages shall be computed from four or more data points, equally spaced over each one-hour period. Data recorded during periods of system breakdown, repairs, calibration checks, and zero and span adjustments shall not be included in the data averages computed under 1.0 of this regulation. An arithmetic or integrated average of all data may be used. The data output of all continuous monitoring systems may be recorded in reduced or nonreduced form (e.g., ppm pollutant and percent O2 or lb/million BTU of pollutant). All excess emissions shall be converted into units of standard using the applicable conversion procedures specified in applicable provisions of this regulation. After conversion into units of the standard, the data may be rounded to the same number of significant digits used in applicable provisions of this regulation to specify the applicable standard (e.g., rounded to the nearest 1% opacity).
1.3.12 Upon written application by an owner or operator, the Secretary may approve alternatives to any monitoring procedures or requirements of 1.0 of this regulation including, but not limited to the following:
1.3.12.1 Alternative monitoring requirements when installation of continuous monitoring system or monitoring devices specified by 1.0 of this regulation would not provide accurate measurements due to liquid water or other substances interfering with the effluent gases.
1.3.12.2 Alternative monitoring requirements when the applicable source is infrequently operated.
1.3.12.3 Alternative monitoring requirements to accommodate continuous monitoring systems that require additional measurements to correct for stack moisture conditions.
1.3.12.4 Alternative locations for installing continuous monitoring systems or monitoring devices when the owner or operator can demonstrate that installation at alternative locations will enable accurate and representative measurements.
1.3.12.5 Alternative methods of converting pollutant concentration measurements to units of the standards.
1.3.12.6 Alternative procedures for performing daily checks of zero and span drift that do not involve use of span gases or test cells.
1.3.12.7 Alternative to the A.S.T.M. test methods or sampling procedures specified by any provision of this regulation.
1.3.12.8 Alternative continuous monitoring systems that do not meet the design or performance requirements in Performance Specification 1, but adequately demonstrate a definite and consistent relationship between its measurements and the measurements of opacity by a system complying with the requirements in Performance Specification 1. The Secretary may require that such demonstration be performed by each applicable source.
1.3.12.9 Alternative monitoring requirements when the effluent from a single applicable source or the combined effluent from two or more applicable sources are released to the atmosphere through more than one point.
1.4 Performance Tests
1.4.1 Within 60 days after achieving the maximum production rate at which the applicable source will be operated, but not later than 180 days after initial startup of such facility and at such other times as may be required by the Secretary, the person responsible for such source shall conduct performance test or tests and furnish the Secretary a written report of the results of such performance test or tests. The Department may conduct or contract for the conduct of a performance test whenever it concludes that such test is necessary to determine compliance.
1.4.2 Performance tests shall be conducted and data reduced in accordance with the test methods and procedures contained in each applicable provision unless the Secretary (1) specifies or approves, in specific cases, the use of a reference method with minor changes in methodology, (2) approves the use of an equivalent method, (3) approves the use of an alternative method the results of which he has determined to be adequate for indicating whether a specific source is in compliance, or (4) waives the requirement for performance tests because the owner or operator of a source has demonstrated by other means to the Secretary's satisfaction that the applicable source is in compliance with the standard.
1.4.3 Performance tests shall be conducted on representative performance of the applicable source. The Secretary may specify additional operating conditions to be tested. The person responsible for the applicable source shall make available to the Department a record of those operating parameters, which the Secretary determines appropriate to establish representative performance of the source. Operations during period of startup, shutdown, and malfunction shall not constitute representative conditions of performance tests unless otherwise specified in the applicable standard. The person responsible for an applicable source shall provide the Secretary 30 days prior notice of the performance test to afford the Secretary the opportunity to have an observer present.
1.4.4 The person responsible for an applicable source shall provide or cause to be provided, performance testing facilities as follows:
1.4.4.1 Sampling ports adequate for test methods applicable to such facility.
1.4.4.2 Safe sampling platform or platforms.
1.4.4.3 Safe access to sampling platform or platforms.
1.4.4.4 Utilities for sampling and testing equipment.
1.4.5 Each performance test shall consist of three separate runs using the applicable test method. Each run shall be conducted for the time and under the conditions specified in the applicable standards. For the purpose of determining compliance, the arithmetic mean of results of the three runs shall apply.
1.5 Compliance with Standard and Maintenance Requirements
1.5.1 Compliance with standards in the regulation, other than opacity standards, shall be determined only by performance test established by 1.4 of this regulation.
1.5.2 Compliance with standards in this regulation shall be determined by Reference Methods 1 through 12 and 15 through 25 set forth in Appendix A, 40 CFR Part 60, revised July 1, 1982, which are hereby adopted by reference. Where the person responsible for the applicable source can provide evidence acceptable to the Secretary that the presence of uncombined water is the only reason for failure to meet the opacity standard such failure shall not be a violation of the standard.
1.5.3 Compliance with opacity standards in this regulation shall be determined by conducting observations at consecutive 15-second intervals for a period of not less than one hour except that the observations may be discontinued whenever a violation of the applicable standard is recorded. The results of continuous monitoring by transmissometer which indicate that the opacity at the time visual observations were made was not in excess of the standard are probative but not conclusive evidence of the actual opacity of an emission, provided that the source shall meet the burden of proving that the instrument used meets, at the time of the alleged violation, Performance Specification 1, has been properly maintained and calibrated and that the resulting data have not been tampered with in any way.
The additional procedures, qualifications and testing to be used for visually determining the opacity of emissions shall be those specified in Section 2 and 3 (except for Section 2.5 and the second sentence of Section 2.4) of Reference Method 9 set forth in Appendix A, 40 CFR Part 60, revised July 1, 1982, which are hereby adopted by reference.
1.5.4 The opacity standards set forth in this regulation shall apply at all times including periods of startup and shutdown unless the emissions during startup and shutdown are governed by an operation permit.
1.5.5 At all times, including periods of startup, shutdown, and malfunction, owners and operators shall, to the extent practicable, maintain and operate any applicable source including associated air pollution control equipment in a manner consistent with good air pollution control practice for minimizing emissions. Determination of whether acceptable operating and maintenance procedures are being used will be based on information available to the Secretary which may include, but is not limited to, monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the source.
1.6 Circumvention. No owner or operator subject to the provisions of 1.0 of this regulation shall build, erect, install, or use any article, machine, equipment or process, the use of which conceals an emission, which would otherwise constitute a violation of an applicable standard. Such concealment includes, but is not limited to, the use of gaseous dilutants to achieve compliance with an opacity standard or with a standard, which is based on the concentration of a pollutant in the gases discharged to the atmosphere.
1.7 General Control Device Requirements. The provisions of Subpart A - General Provisions, Subsection 60.18 of Part 60, Title 40 of the Code of Federal Regulations, July 1, 1986 are hereby adopted by reference with the following changes:
1.7.1 The words "Act" and "Subpart A" are replaced by the words 7 DE Admin. Code 1101, DEFINITIONS AND ADMINISTRATIVE PRINCIPLES of the State of Delaware Regulations Governing the Control of Air Pollution."

9.16 Compliance Provisions
9.16.1 Compliance with the particulate matter emission limitation under 9.12.1.1 of this regulation constitutes compliance with the percent reduction requirements for particulate matter under 9.12.1.2 and 9.12.1.3 of this regulation.
9.16.2 Compliance with the nitrogen oxides emission limitation under 9.14.1 of this regulation constitutes compliance with the percent reduction requirements under 9.14 of this regulation.
9.16.3 The particulate matter emission standards under 9.12 of this regulation and the nitrogen oxides emission standards under 9.14 of this regulation apply at all times except during periods of startup, shutdown, or malfunction. The sulfur dioxide emission standards under 9.13 of this regulation apply at all times except during periods of startup, shutdown, or when both emergency conditions exist and the procedures under 9.16.4 of this regulation are implemented.
9.16.4 During emergency conditions in the principal company, an affected facility with a malfunctioning flue gas desulfurization system may be operated pursuant to a variance, issued under the provisions of 7 Del.C., Ch 60, §6011 or §6012, which requires that sulfur dioxide emissions be minimized by at least the following actions:
9.16.4.1 Operating all operable flue gas desulfurization system modules, and bringing back into operation any malfunctioned module as soon as repairs are completed.
9.16.4.2 Bypassing flue gases around only those flue gas desulfurization system modules that have been taken out of operation because they were incapable of any sulfur dioxide emission reduction or which would have suffered significant physical damage if they had remained in operation, and
9.16.4.3 Designing, constructing, and operating a spare flue gas desulfurization system module for an affected facility larger than 365 MW (1,250 million BTU/hr) heat input (approximately 125 MW electrical output capacity). The Secretary may at his discretion require the owner or operator within 60 days of notification to demonstrate spare module capability. To demonstrate this capability, the owner or operator must demonstrate compliance with the appropriate requirements under 9.13.1, 9.13.2, 9.13.4 and 9.13.7 of this regulation for any period of operation lasting from 24 hours to 30 days when:
9.16.4.3.1 Any one flue gas desulfurization module is not operated.
9.16.4.3.2 The affected facility is operating at the maximum heat input rate,
9.16.4.3.3 The fuel fired during the 24-hour to 30-day period is representative of the type and average sulfur content of fuel used over a typical 30-day period, and
9.16.4.3.4 The owner or operator has given the Secretary at least 30 days notice of the date and period of time over which the demonstration will be performed.
9.16.5 After the initial performance test required under 1.4 of this regulation, compliance with the sulfur dioxide emission limitations and percentage reduction requirements under 9.13 of this regulation and the nitrogen oxides emission limitations under 9.14 of this regulation is based on the average emission rate for 30 successive boiler operating days. A separate performance test is completed at the end of each boiler operating day after the initial performance test, and a new 30 day average emission rate for both sulfur dioxide and nitrogen oxides and a new percent reduction for sulfur dioxide are calculated to show compliance with the standards in 9.0 of this regulation.
9.16.6 For the initial performance test required under 1.4 of this regulation, compliance with the sulfur dioxide emission limitations and percent reduction requirements under 9.13.1 of this regulation and the nitrogen oxides emission limitation under 9.14.1 of this regulation is based on the average emission rates for sulfur dioxide, nitrogen oxides, and percent reduction for sulfur dioxide for the first 30 successive boiler operating days. The initial performance test is the only test in which at least 30 days prior notice is required unless otherwise specified by the Secretary. The initial performance test is to be scheduled so that the first boiler operating day of the 30 successive boiler operating days is completed within 60 days after achieving the maximum production rate at which the affected facility will be operated, but not later than 180 days after initial startup of the facility.
9.16.7 Compliance is determined by calculating the arithmetic average of all hourly emission rates for SO2 and NOx for the 30 successive boiler operating days, except for data obtained during startup, shutdown, malfunction (NOx only), or emergency conditions (SO2 only). Compliance with the percentage reduction requirement for SO2 is determined based on the average inlet and average outlet SO2 emission rates for the 30 successive boiler operating days.
9.16.8 If an owner or operator has not obtained the minimum quantity of emission data as required under 9.17 of this regulation, compliance of the affected facility with the emission requirements under 9.13 and 9.14 of this regulation for the day on which the 30-day period ends may be determined by the Secretary by following the applicable procedures in sections 6.0 and 7.0 of Reference Method 19.
9.17 Emission monitoring
9.17.1 The owner or operator of an affected facility shall install, calibrate, maintain, and operate a continuous monitoring system, and record the output of the system, for measuring the opacity of emissions discharged to the atmosphere, except where gaseous fuel is the only fuel combusted. If opacity interference due to water droplets exists in the stack (for example, from the use of an FGD system), the opacity is monitored upstream of the interference (at the inlet to the FGD system). If opacity interference is experienced at all locations (both at the inlet and outlet of the sulfur dioxide control system), alternate parameters indicative of the particulate matter control system's performance are monitored (subject to the approval of the Secretary).
9.17.2 The owner or operator of an affected facility shall install, calibrate, maintain, and operate a continuous monitoring system, and record the output of the system, for measuring sulfur dioxide emissions, except where natural gas is the only fuel combusted, as follows:
9.17.2.1 Sulfur dioxide emissions are monitored at both the inlet and outlet of the sulfur dioxide control device.

9.17.2.3 An "as fired" fuel monitoring system (upstream of coal pulverizers) meeting the requirements of Method 19 may be used to determine potential sulfur dioxide emissions in place of a continuous sulfur dioxide emissions monitor at the inlet to the sulfur dioxide control device as required under 9.17.2.1 of this regulation.
9.17.3 The owner or operator of an affected facility shall install, calibrate, maintain, and operate a continuous monitoring system, and record the output of the system, for measuring nitrogen oxides emissions discharged to the atmosphere.
9.17.4 The owner or operator of an affected facility shall install, calibrate, maintain, and operate a continuous monitoring system, and record the output of the system, for measuring the oxygen or carbon dioxide content of the flue gases at each location where sulfur dioxide or nitrogen oxides emissions are monitored.
9.17.5 The continuous monitoring systems under 9.17.2, 9.17.3 and 9.17.4 of this regulation are operated and data recorded during all periods of operation of the affected facility including periods of startup, shutdown, malfunction or emergency conditions, except for continuous monitoring system breakdowns, repairs, calibration checks, and zero and span adjustments.
9.17.6 When emission data are not obtained because of continuous monitoring system breakdowns, repairs, calibration checks and zero and span adjustments, emission data will be obtained by using other monitoring systems as approved by the Secretary of the reference methods as described in 9.17.8 of this regulation to provide emission data for a minimum of 18 hours in at least 22 out of 30 successive boiler operating days.
9.17.7 The one-hour averages required under 1.3.11 of this regulation are expressed in ng/J (lbs/million BTU) heat input and used to calculate the average emission rates under 9.16 of this regulation. The one-hour averages are calculated using the data points required under 1.3.11 of this regulation.

9.17.8.2 For Method 6, the minimum sampling time is 20 minutes and the minimum sampling volume is 0.02 dscm (0.71 dscf) for each sample. Samples are taken at approximately 60–minute intervals. Each sample represents a one-hour average.
9.17.8.3 For Method 7, samples are taken at approximately 30-minute intervals. The arithmetic average of these two consecutive samples represent a one-hour average.
9.17.8.4 For Method 3, the oxygen or carbon dioxide sample is to be taken for each hour when continuous SO2 and NOx data are taken or when Methods 6 and 7 are required. Each sample shall be taken for a minimum of 30 minutes in each hour using the integrated bag method specified in Method 3. Each sample represents a one-hour average.
9.17.8.5 For each one-hour average, the emissions expressed in ng/J (lb/million BTU) heat input are determined and used as needed to achieve the minimum data requirements of 9.17.6 of this regulation.

9.18 Compliance determination procedures and methods.
9.18.1 The following procedures and reference methods are used to determine compliance with the standards for particulate matter under 9.12 of this regulation.
9.18.1.1 Method 3 is used for gas analysis when applying Method 5 or Method 17.
9.18.1.2 Method 5 is used for determining particulate matter emissions and associated moisture content. Method 17 may be used for stack gas temperatures less than 160oC (320oF).
9.18.1.3 For Methods 5 or 17, Method 1 is used to select the sampling site and the number of traverse sampling points. The sampling time for each run is at least 120 minutes and the minimum sampling volume is 1.7 dscm (60 dscf) except that smaller sampling times or volumes, when necessitated by process variables or other factors, may be approved by the Secretary.
9.18.1.4 For Method 5, the probe and filter holder heating system in the sampling train is set to provide a gas temperature no greater than 160oC (320oF).
9.18.1.5 For determination of particulate emissions, the oxygen or carbon dioxide sample is obtained simultaneously with each run of Methods 5 or 17 by traversing the duct at the same sampling locations. Method 1 is used for selection of the number of traverse points except that no more than 12 sample points are required.
9.18.1.6 For each run using Methods 5 or 17, the emission rate expressed in ng/J input is determined using the oxygen or carbon dioxide measurements and particulate matter measurements obtained under 9.18 of this regulation, the dry basis Fc factor and the dry basis emission rate calculation procedure contained in Method 19.
9.18.1.7 Prior to the Secretary's issuance of a particulate matter reference method that does not experience sulfuric acid mist interference problems, particulate matter emissions may be sampled prior to a wet flue gas desulfurization system.
9.18.2 The following procedures and methods are used to determine compliance with the sulfur dioxide standards under 9.13 of this regulation.

9.18.2.1.1 Fuel Pretreatment (%Rf):
Determine the present reduction achieved by any fuel pretreatment using the procedures in Method 19. Calculate the average percent reduction for fuel pretreatment on a quarterly basis using fuel analysis data. The determination of % Rf to calculate the percent of potential combustion concentration emitted to the atmosphere is optional. For purposes of determining compliance with any percent reduction requirements under 9.13 of this regulation, any reduction in potential SO2 emissions resulting from the following processes may be credited:
9.18.2.1.1.1 Fuel pretreatment (physical coal cleaning, hydrodesulfurization of fuel, oil, etc.);
9.18.2.1.1.2 Coal pulverizers; and
9.18.2.1.1.3 Bottom and flyash interactions.
9.18.2.1.2 Sulfur Dioxide Control System (%Rg):
Determine the percent sulfur dioxide reduction achieved by any sulfur dioxide control system using emissions rates measured before and after the control system, following the procedures in Method 19; or, a combination of an "as fired" fuel monitor and emission rates measured after the control system, following the procedures in Method 19. When the "as fired" fuel monitor is used, the percent reduction is calculated using the average emission rate from the sulfur dioxide control device and the average SO2 input rate from the "as fired" fuel analysis for 30 successive boiler operating days.
9.18.2.1.3 Overall percent reduction (%Ro):
Determine the overall percent reduction using the results obtained in 9.18.2.1.1 and 9.18.2.1.2 of this regulation following the procedures in Method 19. Results are calculated for each 30-day period using the quarterly average percent sulfur reduction determined for fuel pretreatment from the previous quarter and the sulfur dioxide reduction achieved by a sulfur dioxide control system for each 30-day period in the current quarter.
9.18.2.1.4 Percent emitted (% PCC):
Calculate the percent of potential combustion concentration emitted to the atmosphere using the following equation:
% PCC = 100 – % Ro (9-6)
9.18.2.2 Determine the sulfur dioxide emission rates following the procedures in Method 19.
9.18.3 The procedures and methods outlined in Method 19 are used in conjunction with the 30-day nitrogen-oxides emission data collected under 9.17 of this regulation to determine compliance with the applicable nitrogen oxides standard under 9.14 of this regulation.
9.18.4 Electric utility combined cycle gas turbines are performance tested for particulate matter, sulfur dioxide, and nitrogen oxides using the procedures of Method 19. The sulfur dioxide and nitrogen oxides emission rates from the gas turbine used in Method 19 calculations are determined when the gas turbine is performance tested under subpart GG, 40 CFR, Part 60. The potential uncontrolled particulate matter emission rate from a gas turbine is defined as 17 ng/J (0.04 lb/million BTU) heat input.

The landfill may calculate design capacity in either megagrams or cubic meters for comparison with the exemption values. Any density conversions shall be documented and submitted with the report. For purposes of 7 DE Admin Code 1130, Title V State Operating Permit Program, a landfill with a design capacity less than 2.5 million megagrams or 2.5 million cubic meters does not require an operating permit under 7 DE Admin Code 1130, provided it is not a major source as defined in 7 DE Admin Code 1130. Submittal of the initial design capacity report shall fulfill the requirements of this subpart except as provided for in paragraphs (a)(1) and (a)(2) of this section.”
28.5 Section 60.752(b) shall be replaced with the following language: “Each owner or operator of an MSW landfill having a design capacity equal to or greater than 2.5 million megagrams or 2.5 million cubic meters, shall either comply with paragraph (b)(2) of this section or calculate an NMOC emission rate for the landfill using the procedures specified in Section 60.754. The NMOC emission rate shall be recalculated annually, except as provided in Section 60.757(b)(1)(ii) of this subpart. The owner or operator of an MSW landfill subject to this subpart with a design capacity greater than or equal to 2.5 million megagrams or 2.5 million cubic meters is subject to 7 DE Admin Code 1130. When a landfill is closed, and either never needed control or meets the conditions for control system removal specified in Section 60.752(b)(2)(v) of this subpart, a 7 DE Admin Code 1130 operating permit is no longer required.”
28.6 Section 60.752(b)(2)(ii) shall be replaced with the following language: “Install a collection and control system within 18 months of the submittal of the design plan under paragraph (b)(2)(i) of this section for municipal solid waste landfills that commenced construction, reconstruction, or modification on or after May 30, 1991, and as expeditiously as practicable but not later than September 30, 1998 for all other subject municipal solid waste landfills, that effectively captures the gas generated within the landfill.”
28.7 Section 60.753(g) shall be replaced with the following language: “If monitoring demonstrates that the operational requirement in paragraphs (b), (c), or (d) of this section are not met, corrective action shall be taken as specified in Section 60.755(a)(3) through (5) or Section 60.755(c) of this subpart. If corrective actions are taken as specified in Section 60.755, the monitored exceedance is not a violation of the operational requirements in this section.”
28.8 Delete Section 60.754(c).
28.9 Add new Section 60.757(a)(1)(iv) as follows: “For a subject municipal solid waste landfill not constructed, reconstructed, or modified on or after May 30, 1991, the initial design capacity report shall be submitted the earlier of the date specified in a State construction or operating permit, if applicable, or within 90 days from the effective date of this regulation.”
28.10 Section 60.757(b)(1)(i) shall be replaced with the following language: “The initial NMOC emission rate report shall be submitted with the initial design capacity report required in paragraph (a) of this section. Subsequent NMOC emission rate reports shall be submitted annually thereafter, except as provided for in paragraphs (b)(1)(ii) and (b)(3) of this section.”
