Introduction

The WAQS 2011b modeling platform includes a future projection year for estimating the impacts of future emissions on air quality in the Intermountain West. Emissions projections are only available for the anthropogenic emissions sectors; the natural emissions sectors, including fires, are held constant at the 2011 levels.

Although the projection year for the WAQS 2011b modeling platform is identified as 2025, some of the inventory sectors are projected to other years. This page summarizes the years and data providers of the WAQS 2011b platform future emissions.

2011b Inventory Data

Descriptions of the processing sector abbreviations are available on the WAQS 2011b Base Year Emissions wiki.

3SAQS Phase II Oil and Gas Emissions

WAQS Processing Sectors: arog, ptog

Year(s): 2015, 2020

Data Provider: Ramboll Environ

The majority of the oil and gas basins covered by the 3SAQS Phase II inventory are projected from the year 2011 to 2020. The Williston and Great Plains Basin inventories are projected from 2011 to 2015. These data were developed for the 3SAQS and WAQS by Ramboll Environ.

In December 2015, the Denver-Julesburg Basin projection year inventory was adjusted to reflect recent updates to the activity and control data available from CDPHE. These adjustments lead a net decrease in the 2020 emissions for sources in this D-J Basin, with particularly large decreases in VOC emissions relative to the 3SAQS Phase II projections. Additional details on the D-J Basin adjustments will be available soon.

Other U.S. Anthropogenic Emissions

WAQS Processing Sectors: c1c2rail, c3marine, fdust, nonpt, ft, lv, rwc, nonroad, onroad, usarog, usptog, ptcem, ptncem, ptseca

Year(s): 2025

Data Provider: US EPA

The rest of the anthropogenic emissions for the WAQS 2011b platform are projected to the year 2025, including oil and gas emissions for the basins outside of the 3SAQS Phase II inventory. These data were taken directly from the EPA 2011v2 modeling platform.

Canada Anthropogenic Emissions

WAQS Processing Sectors: canar, canmb, nuspt

Year(s): 2010

Data Provider: US EPA/Environment Canada

The Canadian inventories are held constant at 2010 levels.

Mexico Anthropogenic Emissions

WAQS Processing Sectors: mexar, mexmb, nuspt

Year(s): 2025

Data Provider: US EPA/SEMARNAT/ERG, Inc.

The Mexico inventories are projected from 2008 to 2025 and are based on the latest Mexico NEI developed by SEMARNAT and revised by ERG, Inc.

Natural Emissions

WAQS Processing Sectors: biogenic, wbd, seasalt, lightning, fires

Year(s): 2011

Data Provider: Ramboll Environ and Air Sciences (Fires)

The natural emissions are estimated with 2011 meteorology and 2010 or earlier landuse/landcover data. These emissions are held constant at 2011 levels.

Ancillary Data

Most of the ancillary emissions data (gridding, temporal, chemical speciation) for the WAQS 2011b modeling came from the 2011a modeling platform.
