7 Del. Admin. Code § 1117-7.0

Current through Register Vol. 28, No. 7, January 1, 2025

Section 1117-7.0 - Emission Statement

7.1 Emission Statement requirements apply to all stationary sources located in an ozone nonattainment area that emit nitrogen oxides (NO_x) or volatile organic compounds (VOCs) to the atmosphere. The Department may, with EPA approval, waive the Emission Statement requirements for classes or categories of stationary sources with facility-wide actual emissions of less than 25 tons/year of NO_x or VOCs if the class or category is included in the Base Year and Periodic Ozone SIP Emission Inventories, and the actual emissions were calculated using EPA-approved emission factors or other methods acceptable to the EPA. Emission Statement requirements also apply to all stationary sources located in ozone attainment areas that emit or have the potential to emit 50 tons/year or more of NO_x or VOCs.

7.2 An Emission Statement shall contain data elements addressing source identification information, operating data, actual emissions data, control equipment information and process rate information. Each Emission Statement shall include a certification of the data to ensure that the information contained in the statement is accurate to the best knowledge of the individual certifying the statement. The individual certifying the statement shall be an official of the facility who will take legal responsibility for the Emission Statement's accuracy.

7.2.1 The source identification information provided by the source to the Department shall as a minimum include:

7.2.1.1 Full name;

7.2.1.2 Physical location;

7.2.1.3 Mailing address of the facility.

7.2.2 The minimum operating data provided by the source to the Department shall include:

7.2.2.1 Percentage annual throughput (percentage of annual activity);

7.2.2.2 Hours per day on both the normal operating schedule and during peak ozone season of June 1 through August 31 (if different from the normal operating schedule);

7.2.2.3 Days per week on both the normal operating schedule and during peak ozone season of June 1 through August 31 (if different from the normal operating schedule)

7.2.2.4 Weeks per year on both the normal operating schedule and during peak ozone season of June 1 through August 31 (if different from the normal operating schedule);

7.2.2.5 Start time on both the normal operating schedule and during the peak ozone season from June 1 through August 31;

7.2.2.6 End time on both the normal operating schedule and during the peak ozone season from June 1 through August 31.

7.2.3 The minimum emissions information provided by the source to the Department shall include:

7.2.3.1 Actual volatile organic compound or nitrogen oxide emissions at the process level, in tons per year for an annual emission rate and pounds per day during the peak ozone season from June 1 to August 31 (estimated or measured).

7.2.3.2 Emissions method code for estimated or measured emissions. Valid emissions estimation and measurement method codes and units codes are presented in Table 7-1 and Table 7-2 of this regulation.

7.2.3.3 Units code to identify the units (tons per year or pounds per day) for the units measured or estimated, are presented in Table 7-3 of this regulation.

7.2.3.4 Calendar year for the emissions.

7.2.4 The minimum control equipment information provided by the source to the Department shall include:

7.2.4.1 Current primary and secondary control equipment identification codes. Valid control equipment identification codes are presented in Table 7-4 of this regulation;

7.2.4.2 Current control equipment efficiencies (%);

7.2.4.3 Capture efficiency (%).

7.2.5 The minimum process rate data provided by the source to the Department shall include:

7.2.5.1 Annual fuel/process rate (annual throughput if not a combustion process). For a combustion process, the annual fuel usage must be in units corresponding to the specific Source Classification Code (SCC) for each fuel (e.g., tons for coal, million cubic feet (MMCF) for natural gas). For a noncombustion process, the annual throughput must be given in units of measure corresponding to the specific SCC for the process (e.g., tons of solvent in coating used for metal furniture painting).

7.2.5.2 Peak ozone season daily process rate.

7.2.5.3 Design capacity.

7.2.5.4 Fuel use data (i.e., heat content).

7.2.5.5 Tank data (i.e., vapor pressure, vapor mole weight, diameter, height, age, loading type, color, roof and seal type).

7.2.5.6 Solvent usage data (i.e., solvent purchased and solvent recovered).

7.3 Annual emissions statements are due on April 30 for the preceding calendar year beginning with April 30, 1993 for calendar year 1992. The Department may require more frequent submittal, if the Department determines that either:

7.3.1 A more frequent submission is required by the Environmental Protection Agency; or

7.3.2 Analysis of the data on a more frequent basis is necessary to implement the requirements of 7 Del.C., Chapter 60.
