Annual DelawareToxics Release Inventory (TRI) report shows decreases in emissions to air, water and land

DOVER (Dec. 8, 2014) – The 2013 Toxics Release Inventory (TRI) data and annual report from Delaware’s industrial facilities shows a significant decrease in onsite releases as compared to the state’s 2012 TRI report, good news for Delaware’s environment and for improving public health. Total onsite releases are down 22 percent, with releases to water down 24 percent, releases to air down 10 percent, and releases to land down 50 percent. These reductions show a continued downward trend over the last 15 years, when the reporting requirements were expanded in 1998 to include a larger list of reporting facilities.

The reporting of nitrate compounds released to water again had a major impact on overall onsite releases, accounting for 71 percent (2.8 million pounds) of the total onsite releases. But even nitrate compounds accounted for far less released amounts than in previous years – down by approximately 900,000 pounds compared to 2012. The major changes impacting these reductions are covered below in the Delaware TRI summary and can be found in greater detail throughout the TRI report, which is available on the DNREC website.

“I’m encouraged by the continuing downward trend in onsite releases reported under TRI for the 2013 data year,” said DNREC Secretary David Small. “I’m also confident we can continue this trend even as our economy continues to grow and as industrial productivity moves forward.” 

This year, the TRI report has been expanded to include facility profiles for each 2013 reporting facility. The profiles provide contact information and an overview of each facility, with TRI information presented in several charts and graphical formats. The profiles will provide the public with easier access to TRI information for specific facilities in their communities. 

“The TRI report is a powerful tool,” Secretary Small said. “Not only does it provide a comprehensive indicator of impacts to our air land and water, it can help industry and agencies like ours identify opportunities for enhancing pollution prevention efforts that can produce environmental benefits and economic savings.”

Please refer to the fact sheet below for background on TRI and a summary of the 2013 TRI data. The full TRI 2013 report, facility profiles, and data are available at:

Delaware Toxics Release Inventory
2013 Data and Report 

What is TRI?
The Toxics Release Inventory, or TRI, is a publicly available data set containing information reported annually since 1987 for toxic chemicals manufactured, processed, or otherwise used by certain facilities in Delaware and throughout the United States.  TRI was established in 1986 under Title III, Section 313, of the Federal Superfund Amendments and Reauthorization Act (SARA 313) to provide information to the public about the presence and release of toxic chemicals in their communities. Title III is also known as the Emergency Planning and Community Right-to-Know Act (EPCRA). 

Who must report?
Facilities that are required to the government under TRI must meet the following criteria:

1)    The facility must be covered under the North American Industry Classification System (NAICS) or be a federal facility. Primarily these NAICS codes include manufacturing facilities, oil and coal fired electric facilities, and bulk petroleum terminals.

2)    The facility must have 10 or more full time employees.

3)    The facility must manufacture or process over 25,000 pounds or otherwise use over 10,000 pounds of a TRI chemical. The list of reportable TRI chemicals includes of 593 individual chemicals and 30 chemical categories. Certain chemicals, such as persistent bio-accumulative toxins (PBTs), have lower reporting thresholds. 

What is reported?
Facilities submit reports to Delaware’s Department of Natural Resources and Environmental Control (DNREC) and to the U.S. Environmental Protection Agency (EPA) on the waste management activities for the covered TRI chemicals. These activities include:

1)    Direct releases onsite to the environment. These releases are to air, water, and land.

2)    Waste managed onsite, which includes recycling, treatment, and energy recovery.

3)    Waste managed offsite, which includes recycling, treatment, energy recovery, or disposal.

Data from Delaware facilities is compiled by DNREC and the results are summarized in an annual report. A national analysis of the TRI data is provided by EPA’s annual report. It is noteworthy that TRI only requires reporting of releases and waste management activities, but not amounts used. The control of those releases is achieved separately through a variety of DNREC and EPA permits, laws and regulations. 

Delaware 2013 TRI Results Summary
For 2013, 61 facilities submitted reports for 89 different chemicals. Approximately 4.0 million pounds were reported as being released on-site, a decrease of 1.1 million pounds or 22% compared to 2012. Of this amount, approximately 2.9 million pounds were released to water, while 1.0 million pounds were released to air and approximately 150,000 pounds were released to land.   

TRI Onsite Releases

·         To water: Total on-site releases to water decreased by approximately 900,000 pounds (24%) compared to 2012. 

o   Largest Reductions: Reductions in releases to water were primarily due reductions of nitrate compounds releases reported by Delaware City Refinery and Perdue Georgetown, down 700,000 pounds and 200,000 pounds respectively compared to 2012. 

o   Nitrate compounds were also reported as the largest release to water at 2.85 million pounds, with 2.63 million pounds (92%) released by the Delaware City Refinery and 219,000 (8%) released by Perdue Georgetown. 

·         To air: Onsite releases to air were down approximately 100,000 pounds (10%) compared to 2012. 

o   Reductions in releases to air were reported by several companies, with the largest decrease being reported by the Indian River Generating Station of hydrochloric acid, down 55,000 pounds compared to 2012. 

o   Sulfuric acid was reported as the largest release to air at 278,000 pounds, with the majority being released by the Delaware City Refinery. 

·         To land: Onsite releases to land decreased by 155,000 pounds (10%) compared to 2012. 

o   This reduction was primarily due to reductions reported by Indian River Generating Station for releases of barium compounds to land, which are down 90,000 pounds compared to 2012. 

o   Barium compounds were also the largest reported release to land, with 100,000 pounds reported by Indian River Generating Station. 

Offsite Transfers

·         Waste transferred offsite decreased by 1.8 million pounds (12%) compared to 2012.  Reductions in offsite recycling, offsite energy recovery, and offsite disposal offset increases in off-site treatment and waste sent to publicly owned treatment works (POTWs). 

·         Largest change: The largest reduction reported was for offsite disposal of manganese compounds reported by Dupont Edge Moor, down 817,000 pounds compared to 2012. 

·         Largest chemical amount reported: Lead compounds were the largest reported chemical amount transferred offsite recycling at 4.5 million pounds, with 3.1 million pounds reported by the Johnson Controls Battery Plant, 1.3 million pounds reported by the Johnson Controls Distribution plant, and 100,000 pounds reported by Evraz Claymont Steel.  

Onsite Management

·         Waste managed onsite increased by 1.0 million pounds (0.3%) compared to 2012. Reductions in onsite energy recovery and onsite treatment were offset by an increase in onsite recycling.

·         Largest changes: Multiple facilities reported increases and decreases of over a million pounds for onsite management compared to 2012. The largest reduction reported was for onsite treatment of hydrochloric acid by the DuPont Edge Moor plant, with a reduction of 5 million pounds compared to 2012. The largest increase was for the onsite treatment of hydrogen sulfide by the Delaware City Refinery, up approximately 7 million pounds compared to 2012. 

·         Largest chemical amount reported: Hydrogen sulfide was also the largest reported chemical amount managed onsite, with 336 million pounds being treated onsite, with the majority being reported by the Delaware City Refinery.
