New Standard Practice For Developing Lists of Invasive Plant Species

ASTM has announced that it has begun an initiative to create a standard that 1) describes the criteria and procedures by which to develop an invasive plant list for a defined region and 2) will be useful as the foundation for creating lists of invasive plants to support building codes and related applications. Model building codes and rating systems that aim to improve the environmental performance of buildings and their sites increasingly incorporate clauses to address the ecological damage related to invasive plants in landscaping.

ASTM believes a standard is needed to provide government agencies as well as environmental, academic, and horticultural organizations a common approach to determining what plants are invasive to a specified area. Existing State and Federal noxious weed lists have generally not kept pace with the latest science in the field, and many focus predominantly on agricultural, rather than ecological, impacts. Few local governments have yet to develop their own lists. With definitions dependent on the existence of local, State, and Federal lists, ASTM has concluded that the invasive plant requirements in green building codes will have little effect.

Keokuk, Iowa Receives Grant To Address Combined Sewer Overflows

EPA Region 7 has awarded $291,000 to the City of Keokuk, Iowa, for improvements to its sewer system. The project is expected to be completed by the fall of 2014. The purpose of the project is to construct new sanitary and storm sewer systems, which will eliminate four sewer overflows. The new sewer will provide adequate capacity for both current and anticipated future flows. A long-term strategy has been developed to eliminate six combined sewer overflows in Keokuk that drain either into the Mississippi River or Soap Creek.

Keokuk is one of 10 Iowa cities that have combined sewer systems. These systems typically use one pipe that combines sanitary sewer and storm sewer to the wastewater treatment plants during normal rainfall. However, during rainfall, this system sometimes overflows into nearby streams. and private partners.

Update To Great Lakes Restoration Initiative Action Plan 2015-2019

The Great Lakes Interagency Task Force has scheduled meetings for the public to provide input to a planned update of the Great Lakes Restoration Initiative Action Plan. The updated Action Plan would direct Great Lakes restoration for fiscal years 2015-2019. The public may comment directly to the federal agencies and to the Great Lakes Advisory Board (GLAB), a panel of experts established to provide recommendations to the federal agencies.

Comments may be given at any of the following scheduled meetings:
•May 21-22 - Great Lakes Advisory Board Inaugural Meeting & Public Comment to GLAB
 •May 23 - Webinar
•May 28 - Buffalo, New York.
•May 30 - Milwaukee, Wisconsin.
•June 3 - Webinar
•June 5 - Cleveland, Ohio.

In February 2010, the Task Force released the GLRI Action Plan for FY2010-2014. The Action Plan identified goals, objectives, measurable ecological targets, and specific actions to help rehabilitate the Great Lakes. The Action Plan targets investments to reduce toxic contamination, rehabilitate fish and wildlife habitat, improve nearshore health, reduce nutrients and other land-based pollution, prevent invasive species, and promote accountability, education, and collaboration.

PADEP List of Impaired Waters Approved For 2012

The U.S. Environmental Protection Agency has approved Pennsylvania’s 2012 final list of impaired waters. The list is part of a bi-annual monitoring and assessment report characterizing the condition of Pennsylvania’s surface waters. The 2012 list submitted by the Pennsylvania Department of Environmental Protection (PADEP) contains 7,009 impaired waters, of which 263 are newly listed including portions of Buffalo Creek and Plum Creek in the Upper Juniata watershed. The list also includes more than 650 stream miles within the Susquehanna River Basin that were added or updated in the 2012 list. The new list removes 39 water bodies that were on the previous list including over 96 miles in the Upper Susquehanna-Lackawanna basin and 27 miles of the Lehigh River.

The final report includes a change in the designation for a nearly 100-mile section of the main stem of the Susquehanna River from “unimpaired” for aquatic life and recreational uses, to having insufficient water quality data to make an impairment determination. That change from the draft to the final report reflects comments submitted to PADEP from EPA and others, as well as ongoing efforts to identify the cause of health impacts to the Susquehanna’s smallmouth bass population. PADEP initiated a special study of the fish health problem in 2012 and is continuing its data collection efforts in 2013 to further assess water quality in the Susquehanna River and its major tributaries, and identify the cause(s) for the decline in smallmouth bass. While these steps are underway, the Chesapeake Bay TMDL and accompanying Pennsylvania Watershed Implementation Plans require action to reduce nitrogen, phosphorus and sediment pollution within the Susquehanna watershed.

Final 2012 Iowa Impaired Waters Listing Approved By USEPA

In an April 24, 2013 decision letter, US EPA has approved Iowa’s 2012 list of impaired waters requiring Total Maximum Daily Load (TMDL) calculations. The Iowa Department Natural Resources (IDNR) submitted its impaired waters list to EPA on April 1, 2013, for review and approval as required by the Clean Water Act.

In its decision, EPA approved the removal of 73 water bodies and the addition of 78 water bodies to the Iowa list of impaired waters. The action brings the total number of impaired waters on the state’s list to 479.

As background, a water body is placed on the impaired waters list when monitoring finds that pollutant levels prevent the lake, river, or stream from attaining its beneficial uses. A water body can be removed from the list if it meets its beneficial uses or if a pollution reduction plan (TMDL) for a water body is approved by EPA. Beneficial uses in Iowa include human recreation, water supply, and maintaining healthy aquatic life.

General Permit For Small Dredging Operations Issued By EPA Region 10

US EPA Region 10 has issued a new federal water discharge permit operate small dredge operations in Idaho. Mining for gold using small suction dredges is a popular activity in Idaho with hundreds of dredges in use, especially during the summer. Small-scale suction dredge miners ( defined as using intake nozzles of five inches in diameter or less and engines rated at 15 horsepower or less) will need to apply for coverage under the new Clean Water Act general permit. Larger suction dredges are not covered by this general permit and need to be authorized under a separate individual permit.

To legally operate small suction dredges in Idaho, miners must apply to EPA to be covered by the EPA General Permit, as well as check with the Idaho Department of Water Resources or other state or federal authority for any additional permits that may be required.

The EPA General Permit also contains:

• Special conditions
• Required best practices for dredging equipment operations
• Areas that are open to small suction dredge mining
• Monitoring and reporting requirements

If an operator does not meet the eligibility requirements to be covered under the general permit, they can apply for an individual permit from EPA.

Federal Water Quality Standards Withdrawn For New Jersey, Puerto Rico and San Francisco Bay

EPA is taking final action to amend the federal regulations to withdraw certain human health and aquatic life water quality criteria applicable to waters of New Jersey, Puerto Rico, and California's San Francisco Bay. In 1992, EPA promulgated the National Toxics Rule or NTR to establish numeric water quality criteria for 12 states and two Territories, including New Jersey, Puerto Rico and parts of California. On May 18, 2000, EPA then promulgated a final rule known as the California Toxics Rule or CTR in order to establish numeric water quality criteria for priority toxic pollutants for the State of California that were not previously in the NTR.

These two states and one territory have now adopted, and EPA has approved, water quality criteria for certain pollutants included in the NTR. Because California, New Jersey, and Puerto Rico now have water quality standards that meet the requirements of the Clean Water Act, EPA has determined that the federally promulgated criteria are no longer needed for these pollutants. Therefore EPA is proposing to amend the federal regulations to withdraw those certain criteria applicable to California, New Jersey, and Puerto Rico. The withdrawal of the federally promulgated criteria will enable New Jersey, Puerto Rico, and California to implement their EPA-approved water quality criteria. This final rule is effective on June 3, 2013.

The water quality criteria subject to this action address both freshwater and marine standards and cover a wide range of priority pollutants, including metals, volatile organic chemicals, PAHs, PCBs, pesticides and others EPA has proposed to withdraw only one federal water quality criteria for California - the saltwater aquatic life cyanide criteria for San Francisco Bay. Other criteria for cyanide for waters in California that are currently part of the NTR or CTR will remain unchanged in the federal regulations
