KABAM Version 1.0 User's Guide and Technical Documentation - Appendix A - Description of Bioaccumulation Model
The purpose of this model is to estimate chemical concentrations (CB) and BCF and BAF values for aquatic ecosystems. KABAM is a simulation model used to predict pesticide concentrations in aquatic regions for use in exposure assessments.

KABAM Version 1.0 User's Guide and Technical Documentation - Appendix E - Selection of Bird Species of Concern and Corresponding Biological Parameters
Bird species of concern were identified to define default parameters (body weight and diet composition) to represent birds in KABAM. KABAM is a simulation model used to predict pesticide concentrations in aquatic regions for use in exposure assessments.

Why isn’t there an outdoor air monitor in my county?
EPA and its partners in State, local, and tribal air monitoring programs work closely to design and implement ambient air monitoring networks to meet multiple monitoring objectives including: providing air pollution data to the general public in a timely manner; supporting compliance with the National Ambient Air Quality Standards (NAAQS)…

T-HERPS Version 1.0 User's Guide for Risk to Amphibians and Reptiles from Pesticides
T-HERPS estimates dietary exposure and risk to terrestrial-phase amphibians and reptiles from pesticide use. Currently approved for assessing exposure and risk to the California red-legged frog and terrestrial-phase herptiles with similar dietary behavior

KABAM Version 1.0 User's Guide and Technical Documentation - Appendix C - Explanation of Default Values Representing Biotic Characteristics of Aquatic Ecosystem, Including Food Web Structure
Information relevant to KABAM and explanations of default parameters used to define the 7 trophic levels. KABAM is a simulation model used to predict pesticide concentrations in aquatic regions for use in exposure assessments.

Does the ‘exclude exceptional events’ option exclude only EPA regionally-concurred exceptional events or all flagged events?
Choosing the “Exclude exceptional events data” option excludes all flagged exceptional events, regardless of concurrence. Longer answer – States can flag data that may have been influenced by an exceptional event (e.g. high winds, wildfire). As a user of AirData, you can choose to exclude these flagged data. This option…

What does the POC number refer to?
POC is the Parameter Occurrence Code and is used to uniquely identify a monitor if there is more than one device measuring the same pollutant at a site. The POC number assignment is somewhat arbitrary and varies between sites that are maintained by different state and local agencies. POC designation…
-
Can I include my monitor in the EPA’s monitoring network?
The monitors that make up our monitoring network follow stringent siting and quality assurance criteria and are maintained by state and local agencies. You can read about the monitoring network requirements in 40 CFR part 58. Some states are also beginning to supplement their monitoring network with low-cost sensors; however…
-
Who decides where monitors get placed?
States typically decide where monitors are placed based on areas of relatively high population and/or areas believed to have relatively higher pollutant concentrations. Each state is responsible for developing its own monitoring plan, which is then reviewed and revised every five years. Follow this link for guidance on state and…
-
Why do you use the highest summary statistic (AQI/concentration) among all monitors in an area to represent that area (as opposed to using an average)?
For convenience, we customarily use county and CBSA area definitions for aggregating spatially. And we do typically use the highest daily AQI value among all monitors in each area to represent that area. This practice is consistent with the national ambient air quality standards which strive to ensure that all…
-
Do you provide rankings of cities or states based on air quality?
We do not rank cities or states by air quality, but you can use the AirCompare website to compare air quality among counties in the U.S. based on factors that have been shown to increase risk from air pollution. Return to Frequent Questions about AirData
-
Do you provide outdoor air monitoring data aggregated at the state level?
We don't aggregate concentration data at a state level, primarily because it can, and does, vary widely across any given state. That's why you see monitor-level, county-level, and CBSA-level aggregates on the website. Return to Frequent Questions about AirData
-
Are monthly aggregates available for outdoor air monitoring data?
No, we provide daily and annual summary files. Return to Frequent Questions about AirData
-
When will outdoor air monitoring data for the entire year be available?
EPA regulations give reporting organizations (states, tribes, and local agencies) 90 days following the end of a calendar quarter to submit their data to EPA's Air Quality System (AQS). For Q4 data, reporting organizations have until the end of Q1 (March 31) in the next year to submit to AQS…
