Toxicity Database ToxRedDB Released To Public

U.S. Environmental Protection Agency (EPA) has announced that it is releasing a database, called ToxRefDB, which allows scientists and the interested public to search and download thousands of toxicity testing results on hundreds of chemicals. ToxRefDB incorporates over 30 years of testing results.

ToxRefDB provides detailed chemical toxicity data in an accessible format. It is a part of ACToR (Aggregated Computational Toxicology Resource), an online data warehouse that collects data from about 500 public sources on tens of thousands of environmentally relevant chemicals, including several hundred in ToxRefDB. Users can query a specific chemical and find all available public hazard, exposure, and risk-assessment data, as well as previously unpublished studies related to cancer, reproductive, and developmental toxicity.

ToxRefDB also connects to an EPA chemical screening tool called ToxCast. ToxRefDB contains toxicity information that forms the basis for pesticide risk assessments when combined with other sources of information, such as those on exposure and metabolism.

Energy Star Qualified Building - New EPA Guidelines

The U.S. Environmental Protection Agency (EPA) has announced new, more rigorous guidelines for new homes that earn the Energy Star label. Compared to the current Energy Star guidelines, the new requirements will make qualified new homes at least 20 percent more efficient than homes built to the 2009 International Energy Conservation Code (IECC). These guidelines will go into effect in January 2011, although some builders may choose to adopt the new requirements earlier.

Key elements of the new guidelines for Energy Star qualified homes include:

• A Complete Thermal Enclosure System: Comprehensive air sealing, properly insulated assemblies and high-performance windows enhance comfort, improve durability and reduce utility bills.
• Quality Installed Complete Heating and Cooling Systems: High-efficiency heating and cooling systems engineered to deliver more comfort, moisture control and quiet operation, and equipped with fresh-air ventilation to improve air quality.
• A Complete Water Management System: Because Energy Star homes offer a tightly-sealed and insulated building envelope, a comprehensive package of flashing, moisture barriers, and heavy-duty membrane details is critical to help keep water from roofs, walls, and foundations for improved durability and indoor air quality.
• Efficient Lighting and Appliances: Look for Energy Star qualified lighting, appliances and fans helping to further reduce monthly utility bills and provide high-quality performance.
• Third-Party Verification: Energy Star qualified homes require verification by independent Home Energy Raters who conduct a comprehensive series of detailed inspections and use specialized diagnostic equipment to test system performance.

EPA Hazardous Substance - Hazardous Waste List - Removal of Saccharin

EPA has proposed amending its regulations under the Resource Conservation and Recovery Act (RCRA) to remove saccharin and its salts from the lists of hazardous constituents and commercial chemical products which are hazardous wastes when discarded or intended to be discarded. EPA also proposed amending the regulations under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to remove saccharin and its salts from the list of hazardous substances.

This proposed rule responds to a petition submitted to EPA by the Calorie Control Council (CCC), to remove saccharin and its salts from RCRA and CERCLA. EPA proposed granting the petition based on a review of the evaluations conducted by key public health agencies concerning the carcinogenic and other potential toxicological effects of saccharin and its salts, as well as EPA’s own assessment of the waste generation and management information for saccharin and its salts, which demonstrate that saccharin and its salts do not meet the criteria in the hazardous waste regulations for remaining on EPA’s lists of hazardous constituents, hazardous wastes, and hazardous substances.

The public comment period will be open for 60 days after the proposal is published in the Federal Register.
