The agency will take comments on the proposal for 60 days after its publication. Environmental groups believe that the proposal favors the plan to increase industry profits.

The article reports that the United States Environmental Protection Agency is seeking to clarify the regulatory issue of whether transfers of water require federal clean water permits. This issue has been at the heart of recent court cases. The agency proposed a rule on June 1 stating that transfers from one body of water to another are not subject to National Pollutant Discharge Elimination System permits. Comments on the agency's proposal are due in mid-July, but officials also are keeping an eye on a federal court in Florida, where a key water transfer case is pending.

The article reports that the Environmental Protection Agency (EPA) has proposed a new test to determine when powerplant emissions levels would trigger Nuclear Science Reference (NSR) mandates, such as installing advanced pollution-control systems. Industry welcomed EPA's action but environmental groups criticized it. EPA is offering three options for figuring emissions after a generating unit is modified. EPA says it's aiming for tests that will be applied nationwide. Kim Mastalio, president of Black & Veatch's strategic sales and marketing division, says EPA's proposal would give powerplant managers some clarity about NSR ramifications when they modify boilers or make other improvements.

This article reports that decades of liquid effluent from the Teck-Cominco smelter in British Columbia contributed most of the zinc, lead, cadmium and other trace elements polluting Franklin D.

U.S. Environmental Protection Agency (EPA) asserts it has regulatory authority. Teck-Cominco says it will pay for clean up of pollution it caused, but not under the auspices of EPA or any other U.S. agency.

The article focuses on the U.S. Environmental Protection Agency (EPA), which has agreed to move on North Carolina's request that powerplants in 13 states be required to cut emissions. A settlement reached on February 17 between EPA, North Carolina and the Southern Environmental Law Center compels the agency to decide by August 1 whether coal-fired plants in upwind states are significantly contributing to North Carolina's air quality problems. The settlement, which was filed in U.S. District Court in Raleigh, also requires the agency to determine what actions must be taken to reduce emissions from the plants. The settlement was reached after North Carolina Attorney General Roy Cooper filed a lawsuit to compel EPA to act on a petition filed last March under the Clean Air Act. The petition asked EPA to force coal-fired plants in states as distant as Illinois and Michigan to reduce emissions of nitrogen oxides and sulfur dioxide.

The proposal of altering the plan for curbing powerplant emissions of mercury by the U.S. Environmental Protection Agency (EPA), issued last December, has two options. An emissions-trading program in 2018 to cut mercury by 70%, or requiring "maximum achievable control technology" to trim emissions by 14 tons by 2007. The plan faces growing opposition in the U.S. Congress, from state officials and even from part of the electric power industry. EPA Administrator Michael Leavitt defended the proposal at an April 1, 2004 Senate clean air subcommittee hearing. Leavitt maintains EPA is not seeking "a rollback" of mercury controls because, to date, there has been no such rule. Whatever plan EPA adopts will mean work for the construction industry, says Bob McIlvaine, president of the McIlvaine Co.
