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…
The quality of the indoor air can either impede or assist a school in meeting its core mission -- educating students. Failure to prevent or quickly resolve problems can: Increase the potential for short-term and long-term health problems like asthma, the number one cause of student absenteeism Increase absenteeism of…
The National Academy of Sciences (NAS) published its latest analysis of health research on radon, the Biological Effects of Ionizing Radiation (BEIR VI) Report in 1999 (see www.epa.gov/radon/health-risk-radon#beir). This is the most comprehensive review effort to date. The Committee was charged with: reviewing all current miner and residential data, as…
There is no debate about radon being a lung carcinogen in humans. All major national and international organizations that have examined the health risks of radon agree that it is a lung carcinogen. The scientific community continues to conduct research to refine our understanding of the precise number of deaths…
EPA has a number of resources available: Building Air Quality: A Guide for Building Owners and Facility Managers - Appendix C - Moisture, Mold and Mildew Read the publication "Mold Remediation in Schools and Commercial Buildings Read the publication, "A Brief Guide to Mold, Moisture, and Your Home" Una Breve…
With regard to thresholds in mixtures, how is reporting under Sections 311 and 312 handled if a facility has a number of different mixtures on-site and each is under 10,000 pounds but the mixtures contains an aggregated quantity of an extremely hazardous substance (EHS) that exceeds its reporting threshold? If…
If a facility purchases more than 10,000 pounds of a hazardous chemical for which OSHA requires an MSDS in a calendar year but never actually receives or stores more than the 10,000 pound threshold at one time, must the facility report under EPCRA Sections 311 and 312? The MSDS and…
The definition of "facility" for EPCRA Sections 311 and 312 does not include "motor vehicles, rolling stock and aircraft." Do hazardous chemicals present in cars, trucks, forklifts and other vehicles need to be considered for Sections 311 and 312 reporting as present in the "facility?" Hazardous chemicals present in vehicles…
Do you apply the whole weight of an acid mixture towards the threshold under EPCRA Sections 311 and 312 or just the percentage of acid stated on the material safety data sheet (MSDS)? Aqueous acids are considered mixtures under EPCRA Sections 311 and 312. The acid itself is the hazardous…
Why does EPA recommend submitting a list rather than Material Safety Data Sheets (MSDS) to meet the requirements of Section 311? Lists will minimize the paperwork burden for state and local governments and local fire departments. In addition, the list can be used as an index to inventory forms required…
A facility storing hazardous chemicals on site permanently ceases operations and notifies the State Emergency Response Commission (SERC). Since the facility will no longer be in operation on March 1 of the following year, must the owner/operator of the closed facility submit a Tier I or Tier II hazardous chemical…
Some substantial harm facilities may meet the criteria for a significant and substantial harm facility. After you have prepared and submitted your FRP, the RA may determine that your facility has the potential, not just for substantial harm, but for significant and substantial harm. If the RA makes that determination…
What determines whether a "Regulatory Synonym" is listed for a substance in Table 302.4 of 40 CFR 302.4? In general, no entry is made in the "Regulatory Synonym" column of 40 CFR 302.4, Table 302.4 for a substance if only one chemical name is used to identify that substance under…
Can the "de minimis" concept used in determining the threshold planning quantities in mixtures be applied in the determination of the reportable quantity for emergency release notification? No. The "de minimis" quantity was set in place for threshold planning quantities simply to make the calculation of the total amount of…
