2014 Oil and Gas Emissions Inventories
Contents [hide]
Introduction
This page contains links to all of the WAQS emissions data for oil and gas sources in the Intermountain West. The inventory data will be used for WAQS 2014 (base year) modeling.Inventories
The inventories are a mix of permitted (point) and survey-based (non-point) annual emissions. Descriptions of the files and file formats are provided below.Inventory Summaries
The table below includes links to spreadsheets of the base year (2014) WAQS emissions inventories for selected oil and gas development basins. Brief descriptions of the inventory data are supplemented by additional details of these data in each spreadsheet.Inventories cover 2014 annual time period. Pollutants included in the inventories are NOx, VOC, CO, SO2, and PM10.
Table 1. WAQS 2014 Oil and Gas Emission Inventory Spreadsheets
| Basin | 2014 | Future Year | Description |
|---|---|---|---|
| Big Horn | xls | Nonpoint source emissions were directly provided by Wyoming Department of Environmental Quality (WYDEQ) for all Wyoming counties and emissions for Carbon County, Montana were obtained from 2014 National Emission Inventory (NEI) Final v1. Similarly, the point source emissions were obtained from WYDEQ for Wyoming Counties and 2014 NEI Final v1 for Carbon County, Montana. | |
| Central_Montana_Uplift | xls | Nonpoint source emissions were obtained from 2014 National Emission Inventory (NEI) Final v1 for Montana counties within the basin. Similarly, the point source emissions were also obtained from 2014 NEI Final v1. | |
| Denver-Julesberg | xls | Colorado nonpoint source emissions were obtained from the Colorado Department of Public Health and Environment (CDPHE) submittals to the 2014 National Emission Inventory (NEI) Final v1. Point source emissions were form CDPHE point source data files. | |
| Green River | xls | Nonpoint source emissions were directly provided by Wyoming Department of Environmental Quality (WYDEQ) for all Wyoming counties and obtained from 2014 National Emission Inventory (NEI) Final v1 submitted by Colorado Department of Public Health and Environment (CDPHE) for Colorado counties. Similarly, the point source emissions were obtained from WYDEQ for Wyoming Counties and data provided by CDPHE for Colorado counties. For this study, Green River Basin captures emissions from all counties with the Central Western Overthrust Basin and Green River Basin. | |
| Paradox | xls | Nonpoint source county-wide emissions were obtained from 2014 National Emission Inventory (NEI) Final v1 for Colorado and Utah. For the nonpoint source emissions, tribal and non-tribal emissions were distributed using the appropriate activity. The distribution factor for each county for tribal and non-tribal land is based on the fraction of 2014 activities that occurred on tribal and non-tribal land respectively in each county. Activity data were obtained from the IHS database for the calendar year 2014. Each source category was assigned the activity category surrogate to which it was most closely associated. For example, drill rig activity would be most closely associated with and therefore assigned to new spuds. The point source emissions were obtained from 2014 NEI Final v1 for counties within Utah and point source emissions for counties within Colorado were obtained from the Colorado Department of Public Health and Environment (CDPHE). | |
| Permian | xls | NOx, VOC, CO, SO2, PM10, CO2, CH4, N2O | This spreadsheet contains the oil and gas sources emission inventory for the area and temporal period as listed above. The scope of work is limited to generate emissions from Permian Basin for counties within the New Mexico State. Using oil and gas activity data from the IHS database for calendar year 2014 and input factors from "San Juan and Permian Basin Inputs Factors Report", nonpoint source county and SCC-level bottom-up emissions were estimated. Nonpoint source emissions were assigned, tribal, private/state or federal mineral designation by disaggregating county and SCC-level emissions by the fraction of oil and gas activity surrogate occurring on each mineral designation. Oil and gas activity data were obtained from the IHS database for calendar year 2014. Each source category was assigned the oil and gas activity surrogate to which its emissions are most closely associated. For example, drill rig emissions are most closely associated with and therefore assigned based on spud activity. Major and Minor point source emissions were obtained from New Mexico Environmental Department (NMED). Point source emissions mineral designation were provided by Bureau of Land Management (BLM) for each point source. It should be noted that for point sources were SCC information was not provided, emissions from all greenhouse gas (GHG) pollutants i.e. CO2, CH4 and N2O were not estimated. |
