Toxics Release Inventory Data. The Toxics Release Inventory (TRI) is a publicly available EPA database that contains information on toxic chemical releases and waste management activities reported annually by facilities in certain industries as well as federal facilities. The data contained in this dataset is TRI's Current Data, which is updated several times per year to reflect the latest report revisions and withdrawals that are received from TRI facilities. The Current Data differs from TRI's National Analysis data, which is a static dataset that is generally released in December of each year, and TRI Preliminary Data, which is released soon after the July 1st reporting deadline (see http://www.epa.gov/tri/tridata/preliminarydataset/index.html). More information about the TRI Reporting Cycle can be found at http://www.epa.gov/tri/triprogram/bussinesscycle/busprocess.html

This dataset consists of the non confidential identities of chemical substances submitted under the Toxic Substances Control Act (TSCA). TSCA was enacted to ensure that chemicals manufactured, imported, processed, or distributed in commerce, or used or disposed of in the United States do not pose any unreasonable risks to human health or the environment. EPA adds chemical substances to the TSCA Inventory following EPA's receipt of a Notice of Commencement (NOC) signaling the manufacturer's intent to produce a chemical substance that EPA has previously reviewed and approved. Since EPA published the final TSCA Inventory Reporting Rule on December 23, 1977, the TSCA Inventory has grown to include the identities of over 83,000 chemical substances.

Materials Discarded in the U.S. Municipal Waste Stream, 1960 to 2009 (in tons)

The U.S. Environmental Protection Agency (EPA) has collected and reported data on the generation and disposal of waste in the United States for more than 30 years. We use this information to measure the success of waste reduction and recycling programs across the country. Our trash, or municipal solid waste (MSW), is made up of the things we commonly use and then throw away. These materials include items such as packaging, food scraps, grass clippings, sofas, computers, tires, and refrigerators. MSW does not include industrial, hazardĀous, or construction waste.
The data on Materials Discarded in the Municipal Waste Stream, 1960 to 2009, provides estimated data in thousands of tons discarded after recycling and compost recovery for the years 1960, 1970, 1980, 1990, 2000, 2005, 2007, 2008, and 2009. In this data set, discards include combustion with energy recovery. This data table does not include construction & demolition debris, industrial process wastes, or certain other wastes. The "Other" category includes electrolytes in batteries and fluff pulp, feces, and urine in disposable diapers. Details may not add to totals due to rounding.

Grand Traverse Overall Supply Air Monitoring
Grand Traverse Overall Supply Air Monitoring
Environment

EPA is conducting soil remediation: contaminated soils are being excavated and hauled offsite to an approved landfill. During soil excavation and backfill activities, we will collect air samples each day to monitor the ambient air for volatile organic compounds (VOCs). At the end of each day, the four summa canisters that have been taking readings will be sent to a lab for analysis. We are measuring approximately 30 different VOCs using the standard lab method TO-15. Results will be compared to the Michigan ambient air standards.
Acronyms:
AA: Ambient Air
EA: Excavation Area
PN: Perimeter North
PNW: Perimeter Northwest
PS: Perimeter South
PSW: Perimeter Southwest
ppb: Parts per billion
RPD: Relative Percent Difference
RL: Reporting Limit
MDL: Method Detection Limit
Qualifier definitions:
*: Recovery or RPD exceeds control limits
B: Compound was found in the blank and sample.
J: Result is less than the RL but greater than or equal to the MDL and the concentration is an approximate value.
U: Indicates the analyte was analyzed for but not detected.

Toxics Release Inventory Chemicals by Groupings

Geography and Environment
tri, toxics release inventory, chemicals, core set, ...
The Toxics Release Inventory (TRI) makes available information for more than 600 toxic chemicals that are being used, manufactured, treated, transported, or released into the environment since 1987. EPA makes changes (additions, deletions, or changes in definition) to the TRI chemical list. As a result, the TRI list of reportable toxic chemicals can vary from year to year. EPA created groupings such as the core chemical lists (of 1988, 1991, 1995, 1998, 2000, and 2001) to facilitate year-to-year comparison based on a consistent set of reporting requirements and assure that changes in TRI release or other waste management amounts do not reflect the addition, deletion, or change in definition of reportable chemicals.
EPA also created groupings of specific chemicals of interest by categories such as Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Hazardous Air Pollutants (HAPs), Metals, Newly Added TRI Chemicals in 1995, Occupational Safety and Health Administration (OSHA, Carcinogens), Persistent Bioaccumulative and Toxic (PBT) Chemicals, and Priority Chemicals.
