FAQ Adirondacks

What are the chemistry trends?

Is pH significantly improved?

Are the fish returning?

Does that have an effect on loons or osprey in the Park?

Is the whole park recovering the same way or is there a regional/geographic limit to the response?

State Acid Deposition Control Act of 1984Specific mandates to reduce sulfur dioxide and nitrogen oxide emissions. NY Times Headline “State’s New Law is First in Nation to Curb Acid Rain” • Designate receptor areas in NYS which are sensitive to acid

deposition;• Establish an Environmental Threshold Value for wet sulfate

deposition at each (Adirondacks, Catskills, Hudson Highlands) sensitive receptor area (20 kg/ha/yr);

• Formulate a preliminary final control target and an interim control target for fuel sulfur limitations;

• Develop a sulfur dioxide emissions control program to meet needed sulfur deposition reductions in sensitive receptor areas.

1990 Clean Air Act Amendments – Title IV (Acid Rain)

• The development of a comprehensive national acid rain program.

• Requires removal of 12.5 million tons of SO2 and NOx from utility sector.

• Creates an allowance program for existing and new units.• Establishes continuous emission monitoring program.• Establishes an absolute cap that can be emitted after 2000. • Offers sources several ways to comply.Major point: All good things have their genesis in State Environmental Quality Programs.

Data & Division of Water• All waters of the state are classified to

represent their best uses.• NY water quality standards protect

these best uses.• Monitoring data is needed to evaluate

water conditions.• When a waterbody does not support its

best uses, it is listed on the CWA Section 303(d) list.

• NYS must develop a total maximum daily load (TMDL) or other strategy to restore the waterbody.

21

“Official” Success• Designated “forever wild” in

NYS Constitution.• TMDL for Acid Impaired

Lakes in the Adirondack Park numeric water quality target is appropriate endpoint (ANC >11 ueq/L; Brooktrout Lake = 12.3 ueq/L) & evidence of successful reproduction!

Degradation and recovery of soils and forests(two Adirondack Park sentinel species)

SUGAR MAPLE Acid rain depletes soil base cations. Health = available calcium in the soil. Low levels = stress = Asian longhorn beetle, forest tent caterpillar, others.

RED SPRUCEHigh elevation species. Double whammy. Exposed to extra acid load from cloud water. In these naturally low nutrient soils acid rain chemically forces dissolved aluminum into the soil water. Toxic to trees (just like to fish). Very rapid, highly visible decline in the mid-60s, signature species across the northeast forest. Years of forest transect research. Now recovering.

FAQ Adirondacks (good, simple questions; answers not so simple)What are the chemistry trends? S decline all lakes, N declining in over half, seasonal peaks diminishing.Is pH significantly improved? Yes, but seasonal peaks still a concern.Are the fish returning? Yes, but slowly, selected places.Does that have an effect on loons or osprey in the Park? When fish recover and toxic mercury declines, loons are better fed, more focused(on raising their young).Is the whole park recovering the same or is there a regional/geographic limit to the response? The entire park is experiencing significantly less acid deposition. Responses vary because sensitivities vary, e.g. high elevation, small streams, thin till lakes; biota vary and time lags occur because species take a while to come back.
