Analysis of point source emissions in the Texas-Mexico border region
Pollutant emissions in the Texas-Mexico border were investigated using an emission database that covers 25 Texas counties and the states of Coahuila, Chihuahua, Nuevo Leon and Tamaulipas in Mexico. Major emissions are from energy generation, mainly from two coal-fired facilities in Coahuila, which also generate most of carbon dioxide. Texas exhibits a larger concentration of sources; around ...

EMEP/EEA air pollutant emission inventory guidebook — 2009
The EMEP/EEA Air Pollutant Emission Inventory Guidebook (formerly referred to as the EMEP CORINAIR Guidebook) provides guidance on estimating emissions from both anthropogenic and natural emission sources. It is designed to facilitate reporting of emission inventories by countries to the UNECE LRTAP Convention and the EU NEC Directive. The Guidebook is prepared by the UNECE/EMEP Task Force on ...

Development and first tests of a data assimilation algorithm in a Lagrangian puff atmospheric dispersion model
The development of a Data Assimilation algorithm based on variational approach that allows estimation of source emission rate in Lagrangian particle/puff Atmospheric Dispersion Models for non-stationary (wind and source) conditions is presented. The one-dimensional tests including constant and variable in time source emission rate and wind velocity showed that methodology can be extended to take ...

Comparative sensitivity study for operational short range atmospheric dispersion models
Eight atmospheric dispersion models are compared in a sensitivity study in which the responses towards variations in model input parameters are evaluated. For a single source the values of eight practical model input parameters are varied. The model response is evaluated by examining the maximum value of the 98th percentile of the hourly averaged concentration values. The results are represented ...

Air–quality impact of PM10 emission in urban centres
This paper calculates a detailed inventory of PM10 emissions in the urban area of Mendoza, Argentina, and evaluates the impact of such emissions by using the CALPUFF dispersion program. It includes direct and indirect emissions from mobile sources; emissions from industrial sources and fugitive emissions from unpaved road and dust production from bare land. The main results show the relevance of ...

Modeling Tip: Using Hourly Emission File Editor in BREEZE AERMOD
BREEZE AERMOD includes numerous time-saving tools to help with setting up a modeling run. One of these tools is the Hourly Emission File Editor. This modeling tip explains how to use that tool to easily use refined hourly emission rate data in your AERMOD runs. AERMOD offers many options for capturing the variability of emission rates and other source parameters. Emission rates can be varied by ...

How to compile a greenhouse gas emissions registry
With the federal government debating the best way to reduce greenhouse gas emissions on a national scale, policymakers must also address the need to collect the emissions data necessary to ensure the success of US climate change policies. The first step in reducing emissions is to measure them. Without accurate and complete data on the sources of emissions and the amount they emit, the success of ...

Determinating the influence of different PM 10 sources on air quality in Ljubljana basin with CALPUFF dispersion model
Ljubljana has an unfavourable geographical location in the basin, almost entirely surrounded by high hills. Winds in the basin are often weak and situations with temperature inversion are very frequent, therefore, many PM 10 daily limit value exceedances were observed in 2011. The Directive 2008/50/EC (EU, 2008) requires member states to adjust or provide new air quality plans in order to ...

Enterprise Carbon Accounting: The quest for unprecedented transparency
Enterprise carbon accounting (ECA) is an essential requirement for companies and will likely become necessary due to government legislation. No longer is it permissible for a company to look within its borders, but it must look at its overall environmental responsibilities and accurately gauge and measure carbon production and emission caused by its very existence. Financial data must be directly ...

PSD Applicability- Routine Maintenance and Emissions Change Issues
Introduction This document details how the U.S. EPA (EPA) implemented key aspects of PSD permit applicability from the 1930s to the present and how the regulated community's interpretation of EPA's regulations, policy, and guidance evolved over the same time period. The focus is on the definition and use of the routine maintenance, repair and replacement exclusion and on various aspects of the ...

Modelling emission, concentration and deposition of sodium for Poland
The aim of this paper was to calculate natural and anthropogenic emission of Na+ and to estimate, with the FRAME model, annual air concentration and deposition of Na+ for the domain covering Poland. Calculations of natural emissions included marine emission and wind blown dust from land. Anthropogenic emission was calculated for both point and area sources. Emission maps were used in fine ...

SEC’s Proposal has Implications for Climate-related Disclosures for ESG: Real Time Data?
On March 21, 2022, the Securities and Exchange Commission (“SEC”) released proposed rules on climate disclosures for publicly traded companies entitled “The Enhancement and Standardization of Climate-Related Disclosures for Investors.” This sets the stage to require more companies to collect and validate their greenhouse gas (GHG) emissions data. The SEC has cautioned ...

Federal GHG reporting rule proposed
On March 10, 2009, EPA proposed federal greenhouse gas (GHG) reporting requirements as authorized by the FY08 Omnibus Appropriations Act (H.R. 2794; Public Law 110-161), signed Dec. 26, 2007. EPA developed the rule to collect comprehensive GHG emissions data that can be used to inform EPA and government agencies for future policy decisions. EPA’s rulemaking approach used screening criteria ...

An Expert System for Source-Term Analysis and Accidental Release Modeling
Title III of the Clean Air Act Amendments (CAAA) of 1990 requires establishing regulations to prevent the accidental release and to minimize the consequence of any such release of chemicals listed under 40 CFR Part 68. There is a need for a systematic approach for applying mathematical models to estimate the impact from the large number of potential release scenarios associated with these ...

Modeling emissions from offshore drilling
To regulate drilling activities proposed by oil and gas companies in the oil-rich Gulf of Mexico (GOM), governing agencies require the submittal and approval of certain plan documents before drilling activities can be initiated. For drilling activities in the Western GOM, these plans typically consist of one of the following: EP, or Exploration Plan – required to conduct exploratory ...
