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…
If a facility that is subject to the risk management program regulations in 40 CFR Part 68 is sold to another owner, is the facility required to make a correction or a full update of its risk management plan (RMP)? If there are no changes in the covered operations at…
How does a new Preparer get access to a Risk Management Plan (RMP) via RMP*eSubmit? First, the person must register with CDX. To register with CDX, go to https://cdx.epa.gov/ and complete the registration process for a Risk Management Plan “Preparer”. Once set up as a “Preparer”, the Certifying Official needs…
Hourly emissions data files are available from the Clean Air Markets Division of EPA, collected as part of 40 CFR Part 75. The download location has changed in February, 2023. The new location is https://campd.epa.gov/data/bulk-data-files. Once on this new site, use the menu (at the left) and the Keyword search…
The raw data and summaries that are still available (dating back to 1990) can be obtained from the web page https://www.epa.gov/air-emissions-inventories/pollutant-emissions-summary-files-earlier-neis. Starting with 2001 data, a more limited selection of summary files are available.
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.
The various parts of PM in the NEI are related as follows. PM10-FIL > PM25-FIL because PM10-FIL includes PM25-FIL PM25-PRI = PM25-FIL + PM-CON This equation only applies at the process level. Because some sources only can report PM2.5 (due to test method differences), this equation does not apply to…
Primary PM2.5 estimates are speciated into the five PM species in the NEI: elemental (black) carbon (EC), organic carbon (OC), nitrate (NO3), sulfate (SO4), and the remainder of PM25-PRI (PMFINE). Diesel engine PM25-PRI and PM10 emissions are also labeled as DIESEL-PM25 and DIESEL-PM10 for mobile source diesel engines. For all…
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…
Pursuant to 40 CFR Part 68, Subpart G, the owner or operator of a stationary source subject to the risk management program regulations in Part 68 must develop and submit a risk management plan (RMP). Does the owner or operator have to maintain a written copy of the RMP on…
If a facility is sold to a new owner, does it keep its' original RMP Facility ID number? Yes. The facility will keep the ID number assigned by EPA.
If a facility deregisters, then reregisters, should the facility use the original RMP Facility ID or will it be assigned a new ID? The facility should use the original ID assigned by EPA.
A covered facility deregisters its RMP because it no longer has more than a threshold quantity of a regulated substance in a covered process. If the facility becomes subject to the CAA §112(r) risk management program regulations at a later date and submits a new RMP, should the facility submit…
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…
