Onsite sewage system regulation along the Great Lakes and the US EPA Homeowner Awareness model
No full textAccording to the United States Environmental Protection Agency (US EPA), a significant percentage of residential onsite sewage systems (OSSs) are failing at any given time. The US EPA has therefore issued a set of recommended guidelines for OSS regulatory programs aimed at reducing overall failure rates. We conducted a survey of OSS regulatory program administrators with jurisdictions bordering a Great Lake. Our goal was to determine their programs\u27 capacities to meet the US EPA\u27s recommendalions. We found that although some local programs meet the US EPA\u27s recommendations, most do not. In this article, we present our findings and conclusions for one of the US EPA\u27s models, the baseline Homeowner Awareness model. Most areas do not have recommended requirements that systems be inspected when properties transfer between owners. A majority do not track changes in ownership within the computerized databases they use to record information about systems. Although most provide at least one-time information to homeowners regarding proper OSS maintenance, most do not contact them periodically with reminders of needed maintenance. We include recommendations for resolving some of the issues that our research identified

Link to download instructions
This S3 bucket contains CMAQ-ready emissions, initial, and boundary conditions input files suitable for running a simulation using the CRACMM2 chemical mechanism.
Model-ready emissions inputs using CRACMM2 speciation and files linking representative day emissions to specific calendar days are located under
2022_12US1/emis/cracmmv2_20241031/ and 2022_12US1/emis/emis_dates/
Boundary conditions files are located under 2022_12US1/icbc/CMAQv54_2022_108NHEMI_STAGE_CRACCM2_FROM_CB6R5M/
An initial conditions file for December 22, 2021 is located under 2022_12US1/icbc/
Meteorology Inputs
The meteorology used in processing these emissions and suitable for running CMAQv5.5 can be found at https://registry.opendata.aws/epa-2022-modeling-platform/
Emissions Inputs
2022 CRACMMv2 2022v1 (2022hc) emissions (labeled '2022r1') largely follow the 2022 modeling platform inventory methods used to generate the data available from this AWS S3 bucket except for CRACMMv2 speciation (Skipper et al., 2024). Mobile emissions have been further updated to follow Murphy et al. 2023.
In addition, and new to CRACMM2, CRACMM2 changes how emissions inventories of primary organic aerosol (POA) are allocated to model species of different volatility and functionality. In CRACMM2, POA emissions are assigned to CRACMM species in S2S-Tool+SMOKE and present in the CMAQ-ready files with CRACMM names. The POA inventory is aligned with species of saturation concentrations of 100 µg/m3 and below as described by Pye et al. (2025). DESID should not be used to apply POA volatility profiles to emissions as they have already been applied upstream.
However, in the case of the residential wood combustion files included in this dataset, an additional adjustment (not available at the time of CRACMM2 nor when these emissions were created) is recommended at runtime in DESID. See the “Scale Fire ROC Emissions to account for organic compound volatility” section in the CMAQv5.5 CMAQ_Control_DESID_cracmm2_2022r1.nml namelist file for further details. These files are located under the scripts directory.
Boundary and Initial Conditions Inputs for 12US1 CMAQ CRACMM2 Simulation
Hourly values from a simulation over the Northern Hemisphere performed with a modified version of CMAQv5.4 using the CB6R5M_AE7_AQ mechanism updated to include aerosol nitrate photolysis as described in Sarwar et al. (2024). Mapping of CB6R5M_AE7_AQ to CRACMM2 mechanism species was performed using this file provided in the CMAQ github code repository. The following is a list of input files and science options used in these hemispheric CMAQ simulations.
No bi-directional NH3 air-surface exchange
STAGE module for dry deposition
Online windblown dust module turned on
Chemical mechanism: cb6r5m updated to include aerosol nitrate photolysis as described in Sarwar et al. (2024)
Aerosol module: aero7
Domain: Northern Hemisphere using a 108 km grid size and Polar Stereographic projection assuming a spherical earth with radius 6370.0 km.
Vertical Resolution: 44 layers from the surface to 50 mb
Meteorological fields: WRF4.4.1
Emissions: 2019 HTAP v3.0 anthropogenic emissions + GEIA lightning NO + CAMS biogenic VOC + CAMS soil NO.
Initial conditions for December 22, 2021 and hourly boundary conditions for the December 22 – 31, 2021 spin-up period were generated from a 36 km simulation over North America performed with CMAQv5.4 using the CB6R5_AE7_AQ mechanism. Mapping of CB6R5_AE7_AQ to CRACMM2 mechanism species was performed using the same approach as described above for CB6R5M_AE7_AQ but removing the species specific to detailed marine chemistry.
Additional required inputs for CMAQ
In addition to these meteorology, emissions, initial, and boundary conditions files, users will also need certain other mechanism and time independent input files to perform a 2022 12US1 simulation of CMAQv5.5 using CRACMM2. The following files are included with this 2022 data repository:
GRIDDESC grid description file for the 12US1 domain
12US1 grid mask file for US states (can be used with DESID or ISAM)
Gridded normalized biogenic emission factors for running with inline BEISv4
EPIC files needed when running with bi-directionaly NH3 air-surface exchange
Lighting NO files based on lightning data from WWLLN
Land surface files needed for running with inline biogenics from MEGAN
Ocean files (needed for sea spray emissions)
Scripts and control files
Example run script and CMAQ Control DESID file for running CMAQv5.5 with these 2022 input files.

File Format
The 2022 model inputs are stored as uncompressed netcdf formatted files using I/O API data structures. Information on the model projection and grid structure is contained in the header information of the netcdf files. The netcdf files can be opened and manipulated using I/O API utilities (e.g. M3XTRACT, M3WNDW) or other software programs that can read and write netcdf formatted files (e.g. Fortran, R, Python).
CRACMM2 emissions are compatible with the CRACMM1 mechanism

2014 version 7.1 NEI Emissions Modeling Platform
No full textIntroduction
This 2014 modeling platform includes all criteria air pollutants and precursors (CAPs), two groups of hazardous air pollutants (HAPs) and diesel particulate matter. The first group of HAPs are those explicitly used by the chemical mechanism in the Community Multiscale Air Quality (CMAQ) model for ozone/particulate matter (PM): chlorine (Cl), hydrogen chloride (HCl), benzene, acetaldehyde, formaldehyde, methanol, naphthalene. The second group consists of 51 HAPs or HAP groups (such as polycyclic aromatic hydrocarbon groups) added to CMAQ for the purposes of air quality modeling for the 2014 National Air Toxics Assessment (NATA). The latter five HAPs in the first group are also abbreviated as NBAFM in subsequent sections of the document. A list of all HAPs and diesel species in this modeling platform is in Appendix A. This platform is called the “2014 NATA-Based Platform, version 7.1” (2014v7.1) because it is a HAP-CAP used primarily for NATA. Here, “version 7.1” denotes an evolution from the earlier versions of the 2014-based platform. Version 7.0 supported the initial modeling for NATA. A version subsequent to that supported a CAP application of the 2014 NEI. Both platforms were the starting point for a number of the ancillary (non-emissions) data files for version 7.1.
The 2014v7.1 platform was used to support the 2014 NATA, the focus of which is multipollutant modeling of HAPs and CAPs using CMAQ version 5.2 multipollutant. The CMAQ modeling domain includes the lower 48 states and parts of Canada and Mexico. The 2014 NATA also utilizes the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD), which is an air dispersion modeling system, for all NEI HAPs (about 130 more than covered by CMAQ) across all 50 states, Puerto Rico and the Virgin Islands. Emissions preparation for AERMOD is discussed elsewhere.
