Samples of precipitation such as rain, snow or sleet are collected at more than 25 stations across the U.S. Samples are collected using specially designed precipitation collection devices which funnel the precipitation into a bucket for transfer to a shipping container. EPA’s National Analytical Radiation Environmental Laboratory (NAREL) receives the…
As part of the hazard assessment, owners and operators of Program 2 and Program 3 covered processes must identify and analyze alternative release scenarios (40 CFR §68.28). What criteria should be used when selecting an alternative release scenario? The owner or operator of a stationary source subject to the risk…
The EPA’s RadNet monitoring network is designed to track fluctuations in airborne radioactive particles. RadNet does not track non-ionizing radiation that comes from power lines, transmitters, or cell phone networks like 5G.
EPA reports RadNet laboratory results in conventional units, as shown below with their international equivalents: Medium Conventional unit International SI unit Air Filter Curie (Ci) per cubic meter (m3) Becquerel (Bq) per cubic meter (m3) Precipitation and drinking water Curie (Ci) per liter (L) Becquerel (Bq) per liter (L) Results…
When selecting the worst-case release scenario for Program 2 and 3 processes as required by 40 CFR §68.25, a stationary source owner or operator must analyze the release scenario that results in the greatest distance to an endpoint. Does the "greatest distance to an endpoint" refer to the greatest total…
For the purpose of the offsite consequence analyses required under 40 CFR Part 68, Subpart B, there are several instances in which data gathered at a local meteorological station may be used to establish the modeling parameters of wind speed, atmospheric stability, temperature, and humidity for the stationary source. How…
For the worst-case and alternative release scenarios of an underground storage tank, should I consider any impact on groundwater, drinking water, or soil? No. As part of the worst-case and alternative release scenarios, you need to define the offsite impacts to the environment (40 CFR §68.33) by listing the environmental…
For the purpose of analyzing the worst-case release scenario required as part of the hazard assessment at 40 CFR Part 68, Subpart B, the worst-case release quantity is identified as the greatest amount held in a single vessel or pipe, taking into account administrative controls that limit the maximum quantity…

The owner or operator of a stationary source covered by the risk management program regulations must conduct a worst-case release scenario analysis as part of the required hazard assessment (40 CFR §68.25). The worst-case release is defined as the release of the largest quantity of a regulated substance from a…
I am trying to complete my worst case release scenario for the Risk Management Plan under §68.25. I understand that I am required to use a wind speed of 1.5 m/s and F atmospheric stability class as specified in §68.22(b), unless I can prove that at no time over the…
The EPA operates 140 radiation air monitors across the United States as part of its RadNet nationwide monitoring system. RadNet air monitors measure gamma radiation emitted from airborne radioactive particles as they collect on the monitor’s air filter. Near-real-time data are continually reviewed by computer, and if the results show…
It is very common for natural background radiation levels to change during precipitation events such as rain, sleet or snow. While there are many more factors that affect radiation levels than just precipitation, radon and radon decay products, which occur naturally may be captured in the precipitation and brought to…
More than 60 drinking water sampling locations reported results in the United States in 2018 as part of the RadNet monitoring network. Drinking water samples are typically collected four times a year from taps and are sent to the EPA’s National Analytical Radiation Environmental Laboratory (NAREL) for analysis. Each of…
