Critical Validation Checks for Subpart TT

Certain validation checks which are considered critical errors must be corrected before you can successfully generate your submission package or upload your XML-based submission. These checks are presented to the reporter when they attempt to generate or regenerate their submission or after they attempt to upload an XML-based submission. These checks are signified with a stop sign in your validation report.   The table below provides a list of critical errors.   Additional technical information that may assist XML uploaders is also available at XML Upload Critical Errors.  If you feel that you have triggered one of these checks in error, or if there’s a reason why your report should be submitted despite the check being triggered, you may submit a request to the e-GGRT Help Desk at GHGReporting@epa.gov.

TT0281-3TTData CompletenessThe value for Equation TT-6 (methane generation, adjusted for oxidation) from the landfill in the reporting year has not been reported. You must enter a value that is greater than zero. You must correct the current value before continuing.
TT0282TTScreen ErrorIf methane is monitored monthly, the number of months substitute data was used to determine the annual average CH4 concentration of landfill gas collected for destruction. This value should be reported as a number of months in the reporting year, and should be within the range of 0 to 12 (months). The value you provided is outside that range. You must correct the current value before continuing.
TT0283-1TTScreen ErrorThe value for the modeled methane generation calculated using Equation TT-1. You must enter a value that is greater than zero. You must correct this before continuing.

TT0284-2TTData CompletenessThe value for Equation TT-1 (modeled methane generation) from the landfill in the reporting year has not been reported. This data element is required.
TT0285TTScreen ErrorQuantity of waste-in-place at the start of the reporting year from design drawings or engineering estimates. The value must be greater than or equal to zero. You must correct the current value before continuing.
TT0286TTData CompletenessQuantity of waste-in-place at the start of the reporting year from design drawings or engineering estimates. Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0288TTData CompletenessAre waste-in-place quantity data known? Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0290TTData CompletenessQuantity of waste-in-place at the start of the reporting year. Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0292TTData CompletenessLandfill design capacity. Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0294TTData CompletenessCumulative quantity of waste placed in the landfill for the years for which disposal quantities are available from company records or from Equation TT-3 of this subpart. Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0296TTScreen ErrorThe year prior to the year when waste disposal data are first available (YrData). The value must be greater than or equal to zero. You must correct the current value before continuing.
TT0297TTData CompletenessThe year prior to the year when waste disposal data are first available (YrData). Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0299TTData CompletenessDo you know the year when the landfill opened? Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0301TTScreen ErrorThe year that the landfill first received waste from company records or 1960 (whichever is more recent). Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams and because you have indicated that you know the year when the landfill opened, this data element is required.
TT0302TTData CompletenessThe year that the landfill first received waste from company records or 1960 (whichever is more recent). This data element should not be reported since you have not indicated that Equation TT-4a (Method #3 on the Waste Stream Information page) was used to calculate waste disposal quantities for the waste stream(s) disposed in your landfill.
TT0304TTScreen ErrorThe number of years, from YrOpen to YrLast in Equation TT-4b, for which annual waste disposal quantities are available from company records or the number of years used to calculate Equation TT-3. The value must be greater than or equal to zero. You must correct the current value before continuing.
TT0305TTData CompletenessThe number of years, from YrOpen to YrLast in Equation TT-4b, for which annual waste disposal quantities are available from company records or the number of years used to calculate Equation TT-3. Because you have indicated that you used Equation TT-4b (Method #4 on the Waste Stream Information page) to estimate historic waste quantities for one or more waste streams, this data element is required.
TT0307TTScreen ErrorQuantity of waste-in-place at the start of the reporting year. The value must be greater than or equal to zero. You must correct the current value before continuing.
TT0308TTScreen ErrorLandfill design capacity. The value must be greater than or equal to zero. You must correct the current value before continuing.
TT0309TTScreen ErrorCumulative quantity of waste placed in the landfill for the years for which disposal quantities are available from company records or from Equation TT-3 of this subpart. The value must be greater than or equal to zero. You must correct the current value before continuing.
