We are carrying out the examination work in line with the requirements of the DNV GL Environmental Passport-Operation a programme aimed at providing a complete certified operational emission inventory
, which addresses all of the emissions covered in MARPOL , explains Dr JE[micro]rg Lampe, Senior Project Engineer for Risk & Safety and Systems Engineering at DNV GL.
Navarro's work includes hazardous waste management and operating permit compliance; groundwater treatment projects, sampling and analyses; wastewater discharge plan oversight; air permit and emission inventory
requirements; drinking water system compliance; petroleum tank system management; National Environmental Policy Act project evaluations; and recycling, waste minimization and pollution prevention.
Quantitative methods for dealing with uncertainty in emission estimates involve the characterization of uncertainty in emission factors and/or activity data, and propagation of uncertainty to a total emission inventory
The Harvard-Nanjing study constructs a "bottom-up" emission inventory
that is specific to China's energy and technology mix and combines the results of Chinese field studies of CO2 emissions from diverse combustion processes with a plant-by-plant data set for power generation, independent research on transportation and rural biomass use, and provincial-level energy statistics for the remaining sectors.
In a report released on Monday, the oil and gas industry groups suggest the figures for methane emissions contained in the EPA's 2010 emission inventory
for natural gas drilling and hydraulic fracturing are inaccurate and inflated.
Navarro's work includes hazardous waste management and operating permit compliance; management of the large-scale groundwater monitoring program; environmental clean-up projects and field investigations; air permit and emission inventory
requirements; drinking water system compliance; petroleum tank system management; National Environmental Policy Act project evaluations and recycling, waste minimization and pollution prevention.
The Community Multiscale Air Quality (CMAQ) model was applied to an emission inventory
to estimate the baseline concentrations and the marginal concentration change associated with hypothetical control strategies for multiple sectors in the YRD.
The Emission Inventory
includes direct GHGs as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), F gases with GHG precursors as nitrous oxides (NOx), non-methane volatile organic compounds (NMVOCs) and carbon monoxide (CO) emissions.
Business owners will develop a greenhouse gas emission inventory
and action plan, she said.
The Daily News said the event included sessions on air pollution and public health; point and non-point source air pollution control; and air monitoring, modeling and emission inventory
The AP-42 value is expressed as a range, from 1-37 pptp, and state regulators required that the maximum of the range be used in the emission inventory
Indeed, notes Steve Bromberg of EPA, assembling an emission inventory
"is still really more of an art than a science.
