FOR IMMEDIATE RELEASE

(Kansas City, Kan., March 13, 2012) - The U.S. Environmental Protection Agency is announcing the addition of the Compass Plaza Well TCE Site to the federal Superfund National Priorities List (NPL). An NPL listing notifies the public that EPA believes a site requires further study and cleanup under EPA's Superfund program.

The Compass Plaza Well TCE Site consists of contaminated ground water that has impacted domestic and irrigation wells. The site includes a small cluster of wells in Greene County near Compass Plaza, a commercial area of Rogersville, Mo. In 2010, following routine public drinking water monitoring by the Missouri Department of Natural Resources (MDNR), trichloroethylene (TCE) was detected in the Compass Plaza strip mall drinking water well and at two nearby public wells. Municipal wells belonging to the City of Rogersville are not contaminated with TCE.

TCE is used in industrial solvents and degreasers as well as household products such as correction fluids, paints, paint removers, adhesives, rug cleaners, metal cleaners and spot removers.

People can be exposed to TCE by breathing contaminated air at home or in the workplace; by drinking, swimming or showering in contaminated water; or through contact with contaminated soil. Industrial emissions of TCE stem mostly from metal degreasing plants and steel pipe and tube manufacturing.

The addition of the Compass Plaza Well TCE Site to the NPL makes the site eligible for federal funds to comprehensively investigate and address site contamination. These funds also guarantee the public an opportunity to fully participate in cleanup decisions.

EPA will work to identify companies or people, potentially responsible parties (PRPs), responsible for the contamination at the site, and require them to conduct or pay for the cleanup. If no viable PRPs are found, EPA will investigate the full extent of the contamination before starting significant cleanup at the site.

EPA Issues New Construction Stormwater General Permit

News release from EPA:


FOR IMMEDIATE RELEASE

EPA Issues Permit for Stormwater Discharges from Construction Sites
New permit includes more protections for waterways, shaped by important public and stakeholder feedback

WASHINGTON – The U.S. Environmental Protection Agency (EPA) is issuing a new permit, in accordance with the Clean Water Act, that will provide streamlined permitting to thousands of construction operators, while protecting our nation’s waterways from discharges of polluted stormwater from construction sites. Stormwater discharges from construction sites can contain harmful pollutants, such as nutrients, that contaminate waters, increase drinking water treatment costs, and damage aquatic ecosystems. The new permit was shaped by important input from the public and stakeholders to ensure that it provides important protections for waterways, while also providing flexibility to operators.

The 2012 construction general permit (CGP) is required under the Clean Water Act and replaces the existing 2008 CGP, which expired on February 15, 2012. The new permit includes a number of enhanced protections for surface waters, including provisions to protect impaired and sensitive waters. Under the Clean Water Act, national pollutant discharge elimination system (NPDES) permits are typically issued for a five-year period, after which time EPA generally issues revised permits based on updated information and requirements, as is the case with today’s announcement. NPDES permits control water pollution by including limits on the amount of pollutants that can be discharged into waterways by specific sources. The permit also provides new flexibilities for operators. For example, it allows for emergency projects (e.g., restoration following a flood or other natural disaster) to begin immediately without permit authorization from EPA, while still retaining full authority for EPA to ensure that the project proceeds in an environmentally responsible manner once it has commenced. The permit also enables operators of already permitted projects flexibility where compliance with a new permit requirement is economically impracticable.  

The 2012 CGP updates include steps intended to limit erosion, minimize pollution sources, provide natural buffers or their equivalent around surface waters, and further restrict discharges to areas impaired by previous pollution discharge.

Many of the permit requirements implement new effluent limitations guidelines and new source performance standards for the construction and development industry that became effective on February 1, 2010, which include pollution control techniques to decrease erosion and sediment pollution.

The permit will be effective in areas where EPA is the permitting authority: Idaho, Massachusetts, New Hampshire, New Mexico, Washington, D.C., and most U.S. territories and in Indian country lands.

EPA invited the public to comment on the draft permit. The agency also had a webcast to introduce owners and operators of construction sites, members of the public, and State or Tribal permitting authorities to the new requirements of the proposed CGP.

EPA & TDSHS Warn Against Eating Contaminated Fish

News release from EPA Region 6:

Thursday, February 2, 2012

EPA and TDSHS Warn Against Consumption of Contaminated Fish

(DALLAS – February 2, 2012) During the week of February 6-12, 2012, representatives from the Environmental Protection Agency (EPA) and the Texas Department of State Health Services (TDSHS) will be in the area of South Alamo, Texas, to speak with residents about the contamination in the Donna Reservoir and Canal. This effort is being made to provide local residents with information about the health risks of consuming fish taken from the Donna Reservoir and Canal. The possession of contaminated fish taken from the reservoir is prohibited by the TDSHS.

The principal pollutants in the reservoir are polychlorinated biphenyls (PCBs). PCBs are a group of synthetic organic chemicals that can cause a number of different harmful effects in humans. The primary risk to human health from PCBs is from suspended sediment in the water and the consumption of contaminated fish. Effects of consumption of contaminated fish may include nausea, vomiting, abdominal pain, skin rashes, acne, and cancer. 

The Donna Reservoir and Canal is an EPA Superfund site located in Hidalgo County in southern Texas just north of the Rio Grande. The site includes the Donna Reservoir, the Donna Main Canal, the West and East Main Canals which extend north from the reservoir, and a series of interconnecting canals.

Oak Ridge Lays Out Big Plans for 2012

From the U.S. Department of Energy's Office of Environmental Management, EM Update, Vol. 4, Issue 1, January 2012


Oak Ridge Lays Out Big Plans for 2012

OAK RIDGE, Tenn. – Last year, Oak Ridge’s Environmental Management (EM) program logged one of its most successful years due to sound project management and achievements in American Recovery and Reinvestment Act work.
Oak Ridge plans to maintain that momentum in 2012, and the year is off to a great start. EM employees are making considerable progress on Oak Ridge’s largest projects, specifically the K-25 Demolition Project and Uranium-233 Disposition Project
“Our employees laid an excellent foundation last year through the Recovery Act and cooperation with our newly selected prime contractor, URS | CH2M Oak Ridge,” said Sue Cange, acting assistant manager for EM in Oak Ridge. “Those efforts have set the stage for an ambitious year, allowing us to make substantial gains in our work to meet requirements with regulators, protection of the environment, and furthering DOE’s other missions onsite.”

Oak Ridge K-25
Employees at Oak Ridge are accelerating work at K-25’s East Wing. Sixty percent of the remaining structure is expected to be down by the end of the September. 

Currently, Oak Ridge’s EM program has a list of 40 active projects with a wide range of scopes and complexity. At the East Tennessee Technology Park (ETTP), employees are removing K-25’s East Wing more rapidly than anticipated, with 26 percent of the 796,000-square-foot structure down and 60 percent planned for demolition by the end of September. Built as part of World War II’s Manhattan Project, K-25 housed the world’s first gaseous diffusion plant for enriching uranium.
EM is making progress finalizing the K-25 site’s historic preservation plans, which have been under negotiation since 2006. A final agreement is expected this spring.
Also at ETTP, pre-demolition work is scheduled to begin shortly in Building K-27. The eventual removal of this highly contaminated, 383,000-square-foot former gaseous diffusion facility will substantially eliminate risks and free millions of dollars in security and maintenance costs for cleanup elsewhere.
At the Oak Ridge National Laboratory (ORNL), employees removed the 4,000-gallon Tank W-1A this month. The tank, located in ORNL’s central campus, was the greatest source of groundwater contamination at the site. From 1951 until 1986, the tank collected and stored liquid waste from radiochemical separations and high-radiation facilities at ORNL, until significant levels of soil and groundwater contamination were traced to the vessel. Currently, employees are removing the surrounding contaminated soils. The project is expected to be complete this summer in accordance with the Tennessee Department of Environment and Conservation (TDEC) and the U.S. Environmental Protection Agency’s (EPA) milestone.

Tank W-1A, a 4,000-gallon contaminated tank buried in Oak Ridge National Laboratory’s central campus, was removed from the site in January.

Also at ORNL, Oak Ridge’s EM program is advancing the Uranium-233 Disposition Project. In late December, the first shipment of inventory from Building 3019 was sent offsite, marking the beginning of the end for the world’s oldest operating nuclear facility. The first phase of shipments is expected to be complete during the next six to nine months.
 At the Y-12 National Security Complex (Y-12), workers continue performing the second round of Recovery Act projects made possible through savings from previous Recovery Act projects. This second round of projects is directed toward mercury mitigation. For example, EM workers are developing an absorption unit to capture and treat mercury-tainted water from a location that is one of the main contributing factors of mercury entering the Upper East Fork Poplar Creek.  
EM is making headway on its National Priorities List (NPL) Site Boundary Delineation Project, which is in the final stages of characterizing 16,000 acres within the Oak Ridge Reservation. When complete, the uncontaminated areas will be removed from the existing NPL. The list, maintained by the EPA, contains sites with known or threatened releases of hazardous substances, pollutants, or contaminants.
Once areas are removed from the list, they can be approved for a greater range of new development and reuse activities. Most water and soil samples have been analyzed and validated, with the final two samples scheduled for completion this month. The overall project remains on schedule to meet a Sept. 30 milestone with TDEC and the EPA.
