7 Del. Admin. Code § 1117-1.0
"Actual emission" means the actual rate of emissions of a pollutant from an emissions unit for the calendar year or seasonal period. Actual emission estimates must include upsets and downtime to parallel the documentation of these events in the emission inventory and must follow an acceptable emission estimation method.
"AIRS" means Aerometric Information Retrieval System (AIRS). EPA's mainframe database of state air emissions data.
"Annual fuel/process rate" means the actual or estimated annual fuel, process or solid waste operating rate. The AIRS facility subsystem source classification code table prescribes the units to be used with each source classification code (SCC).
"Base year" means the year of enactment of the Clean Air Act Amendments, calendar year 1990. Serves as the baseline year for ozone State Implementation Plan (SIP) emission inventories and attainment strategies.
"Capture efficiency" means the weight per unit time of a pollutant entering a capture system and delivered to a control device, divided by the weight per unit time of the total pollutant generated by a source of the pollutant, expressed as a percentage. The capture efficiency reflects how much of the pollutant is captured and routed to the control device. It should not be confused with the control efficiency, which is a reflection of how well the control device controls emissions.
"Certifying individual" means the individual responsible for the completion and certification of the Emission Statement (e.g., officer of the company) and who will take legal responsibility for the Emission Statement's accuracy.
"Control efficiency" means the weight per unit time of a pollutant entering the control device minus the weight per unit time of a pollutant leaving the control device, divided by the weight per unit time of the pollutant entering the control device, expressed as a percentage. The control efficiency reported for Emission Statements and SIP emission inventories should be the measured efficiency, adjusted to an annual average by reflecting any reduction in efficiency due to control equipment downtime and maintenance degradation occurring after the date of measurement. If the measured control efficiency is unavailable, the design efficiency, reduced by 10%, may be used. The downtime and maintenance degradation adjustments are then made to this figure. However, it should be clearly indicated that the design efficiency, and not the measured efficiency, is being reported.
"Control equipment identification code" means the AIRS code that defines the equipment (such as an incinerator or carbon absorber) used to reduce, by destruction or removal, the amount of air pollutant or pollutants in an air stream prior to discharge to the ambient air. Table 7-4 of this regulation describes the acceptable equipment codes for Emission Statements and SIP emission inventories.
"Estimated emissions method code" means a one digit code that identifies the estimation technique used in the calculation of estimated emissions. Table 7-1 of this regulation describes the acceptable emissions method codes for Emission Statements and SIP emission inventories.
"Estimated emissions units" means a two digit code that identifies the units associated with an estimated emissions value. Table 7-3 of this regulation gives the acceptable estimated emissions units for Emission Statements and SIP emission inventories.
"Measured emissions method code" means a one digit code that identifies the test method used to ascertain measured emissions. Table 7-2 of this regulation describes the acceptable measured emissions method codes for Emission Statements and SIP emission inventories.
"Measured emissions units" means a two digit code that identifies the units associated with a measured emissions value. Table 7-3 of this regulation gives the acceptable measured emissions units for Emission Statements and SIP emission inventories.
"Peak ozone season" means that period of the year when conditions for photochemical ozone formation are most favorable. It is characterized by sustained periods of direct sunlight (i.e., long days, small cloud cover) and warm temperatures. For Delaware, the peak ozone season is defined as the period from June 1 through August 31.
"Percentage annual throughput" means an estimate of the quarterly percentage of the annual throughput. For boilers, process heaters or similar combustion equipment the percent throughput for each quarter would be a percentage based on the total fuel burned for the entire reporting year. For a process or non-combustion activity the percent throughput for each quarter would be a percent based on the production, consumption or other throughput units of measure. The sum of the four percentages must equal 100%. For Emission Statements and SIP emission inventories the quarters are defined by EPA as follows:
"Periodic ozone SIP emission inventory" means an inventory of all emissions to the atmosphere of VOC's, NOx, and CO from all categories of emission sources. A periodic ozone SIP inventory must be completed at least every three years after the base year (1990).
"Point" means a physical emission point or activity within a facility that results in pollutant emissions.
"Potential to emit" means the capability of a source to emit any air pollutant at maximum design capacity, except as constrained by federally-enforceable conditions that include the effect of installed air pollution control equipment, restrictions on the hours of operation, and the type or amount of material burned, stored, or processed. Potential to emit is used for major source determinations under New Source Review (NSR).
"Source classification code (SCC)" means an eight digit code used by EPA to identify a process, activity, or segments of a process or activity creating emissions at a point.
"Segment" means components of a process or activity at a point, used in the computation of emissions. Each segment must have an associated SCC. For example, in a combustion process that can burn alternate fuels, each specific fuel is considered a segment, and each has a unique SCC.
