LANDMARK MONTANA PACT REQUIRES EPA STUDY FOR DELISTED WATERS

EPA and Montana environmentalists have signed a landmark agreement requiring the agency for the first time to ensure that waters a state removes from its impaired waters list have been properly assessed and are no longer impaired.

Environmentalists around the country have long argued that many states avoid the resource-intensive process of developing pollutant caps -- called total maximum daily loads (TMDLs) -- for impaired waters by simply removing them from their impaired waters lists without demonstrating that the removals are warranted.

DEFENSE DEPT. READIES STUDIES SHOWING RANGE OF PERCHLORATE SOURCES

The Defense Department is preparing to start funding a series of studies aimed at identifying the growing range of non-military sources of perchlorate, which could help limit the military's cleanup liability of the ubiquitous contaminant but might also lead to the need for additional treatment of wastewater from a host of industrial processes.

Some researchers are also working to distinguish between manmade and naturally occurring forms of the widespread groundwater contaminant, and to understand how the chemical forms under natural conditions.

EPA DEADLINE PROMPTS STATE FEARS OVER NUTRIENT WATER QUALITY CRITERIA

With EPA facing a looming deadline, state water officials are concerned that EPA may step in and promulgate nutrient water quality criteria for states that may lead to overly stringent water quality standards.

However, an EPA official says agency officials are generally "feeling pretty good about where states are" in developing their own nutrient criteria, although the source warns that some states "have done nothing" to develop their own criteria.

Remining refers to additional mining that occurs at abandoned mines or previously mined sites.

EPA PLAN FOR SETTING SELENIUM PERMIT LIMITS COULD BE MODEL FOR MERCURY

EPA is proposing a controversial mathematical formula to calculate permit limits for a new fish tissue-based water quality criterion for selenium that may foreshadow how the agency will develop similar permit limits for its mercury fish tissue standard.

EPA officials say the plan for developing selenium permit limits could draw fire from industry officials opposed to agency efforts to develop a similar plan for mercury.
