Idaho watersheds, USTs in Maine, mercury in Iowa, dioxin in
Michigan, stormwater in North Carolina, and air quality standards in Wyoming
and New Mexico are some of the topics covered in this month's state regulatory
Idaho - Proposed Water Quality Management Plans
The Idaho DEQ has proposed plans to manage
phosphorus in the Weiser River Watershed. Excess phosphorus leads to
eutrophication or over-fertilization of water bodies, which can cause the death
of aquatic life. The plans are based on a recent study of the physical,
chemical and biological conditions of water bodies in the watershed. The
department's goal is to control phosphorus in the Snake River-Hells Canyon, of
which the Weiser River is a tributary.
Iowa - Mercury Found in Fish
The Iowa DNR has confirmed the presence of
mercury in tissue samples from bass and walleye collected in Pool 12 of the
Mississippi River that exceeds consumption advisory levels. Other advisories
have been issued for mercury in the Cedar River from Floyd County north to the
Minnesota border, in the Upper Iowa River from the lower dam in eastern
Winneshiek County upstream 24 miles and in the Volga River, including the
Little Volga and the North Branch Volga River from the town of Volga upstream
in Clayton County. For more information, visit www.iowadnr.gov/fish/index.html

Maine - State Proposes Changes to UST Installer Rules
The Maine DEP has proposed to amend rules 2007-P282 through
P285 that govern underground storage tank (UST) installers. These proposals
would: 1) eliminate certification processes for underground gasoline tank
removers and Class 3 underground tank installers; 2) consolidate the
certification of underground tank installers into a single class; and 3) alter
requirements for apprenticeship of applicants for certification as underground
oil storage tank installers.
Michigan - River Contaminated with Dioxin
Federal EPA officials ordered the state to begin
emergency cleanup activities in the Saginaw River after samples turned up
dioxin levels up to 1.6 million parts per trillion, compared to cleanup
standards of 1,000 parts per trillion. Hot spots of dioxin contamination have
been recorded from Dow Chemical Co.'s Midland plant to the Saginaw Bay since
1978 but never at such high levels. State health officials have issued warnings
not to eat fish from the river.
New Mexico - BACT for Mercury at New Power Plants
The state's Air Quality Bureau has initiated
work on a rule to minimize mercury emissions from new coal-fired power plants.
The new rule will implement House Bill 318, a product of the 2007 legislative
session. The bill provides statutory authority (under the Air Quality Control
Act, NMSA 1978, Section 74-2-5(C)(4)) for the Environmental Improvement Board
to issue a rule requiring that new coal-fired power plants control the greater
of what is achievable with Best Available Control Technology (BACT), or 90
percent of the mercury from the input fuel.
North Carolina - New Coastal Stormwater Rules
The state's Division of Water Quality has held
public hearings to gather comments on proposed changes to stormwater rules that
protect sensitive coastal waters. The division recommended amending the state coastal
stormwater requirements after a study concluded that current rules were not
providing effective protection for aquatic resources, including shellfish
harvesting and recreation.
Wyoming - Revising Air Quality Standards
The Wyoming DEQ's Air Quality Division has
submitted a proposal to the Environmental Quality Council to revise the state's
air quality standards and regulations. Changes affect Chapter 3,
"General Emission Standards," Chapter 5, "National Emission
Standards," Chapter 11, "National Acid Rain Program" and Chapter
14, "Emission Trading Program Regulations." Most of the changes to
Chapters 3, 5, and 11 are updates to the annual effort to adopt by reference
from the Code of Federal Regulations.
